To appreciate ‘clean’ energy applications of the dual-fuel internal combustion engine (D-FICE) with pilot Diesel fuel, to aid public policy formulation in terms of present and future benefits to the modern transportation, stationary power, and promotion of oil and gas “green- drilling”, the brief to an engine research team was to investigate the feasible advantages of dual-fuel compression-ignition engines, guided by the following concerns: (i) Sustainable fuel and engine power delivery? (ii) The requirements for fuel flexibility? (iii) Low exhausts emissions and environmental pollution? (iv) Achieving low specific fuel consumption and economy, for maximum power? (v) The comparative advantages over the conventional Diesel engines? (vi) Thermo-economic modeling and analysis for the optimal blend as basis for a benefit/cost evaluation? Planned in two stages for reduced cost and fast turnaround of results - initial preliminary stage with basic simple models, and advanced stage with more detailed, complex modeling. The paper describes a simplified MATLAB based computational experiment predictive model for the thermodynamic, combustion and engine performance analysis of dual-fuel compression-ignition engine studies operating on the theoretical limited-pressure cycle with several alternative fuel-blends. Environmental implications for extreme temperature moderation are considered by finite-time thermodynamic modeling for maximum power, with predictions for pollutants’ formation and control by reaction rates kinetics analysis of systematic reduced plausible coupled chemistry models through the NCN reaction pathway for the gas-phase reactions classes of interest. Controllable variables for engine-out pollutants emissions reduction and in particular NOx elimination are identified. Verifications and Validations (V&V) through Performance Comparisons were made using a clinical approach in selection of Stroke/Bore ratios greater-than and equal-to one (≥1), low-to-high engine speeds, and medium to high power requirements from data of existing dual-fuel engines and convertible real diesel engines applied in different industry sectors. The results obtained show that dual-fuel engines operating on limited-pressure cycle have economical and environmental advantages in terms of engine efficiency, and fuel consumption; with the engine emissions results showing promise of operating within the desired United Nations’ guide for slow climate change, with reduced carbon dioxide (CO2).

This study was carried out to assess the level of susceptibility or resistance of sibling species of Anopheles gambiae complex from Auyo in Jigawa state between 2013 and 2014 to three classes of insecticides approved by World Health Organization (WHO) for vector control. A. gambiae larvae collected from ecologically contrasting breeding sites were reared to adults in the laboratory. Adults from the F1 progeny were assayed for resistance using the WHO adult insecticide susceptibility bioassay protocol. The mosquitoes were exposed to DDT, Permethrin and Bendiocarb belonging to 3 classes of insecticides approved by WHOPES for malaria vector control. The individual sibling species were identified molecularly and the molecular resistance mechanisms characterized by SINE and kdr PCR methods respectively. The An. gambiae populations tested were highly resistant to DDT and permethrin insecticides but less resistant to bendiocarb. Analysis of the genetic composition of the vector population revealed preponderance of An. coluzzii (> 77%). L1014F and L1014S kdr mutations correlated to insecticide resistance phenotype expression. This study indicates differential distribution of the resistant genotype of Anopheles malaria vector between ecologically different habitats in the area. The information could be useful in decision and planning making for vector control programs in the region.

This paper is focused to analyze the proposed methods for in-situ measurements of electromagnetic fields transmitted by LTE base stations. One of the methods is based on measurements of physical broadcast channel (PBCH) using basic spectrum analyzer, whereas the other method is based on measurements of the reference signal (RS) using a decoder. Both alternatives are proposed to be used for extrapolation to the maximum electromagnetic field exposure level at full base station traffic load. The analysis is conducted with respect to instrument requirements, accuracy and time requirements. Different instrument settings of the spectrum analyzer and their impact on the measurement results is analyzed and discussed. Measurements using the spectrum analyzer method overestimate the electric field strength compared with the LTE decoder method in  70 % of all measurement cases in this work. All spectrum analyzer based measurements conducted in the main beam of an antenna at distances of less than 100 m were within ± 20% compared with the decoder results. Measurement results obtained in a reflective environment show that both methods are affected by fading, but significant deviations between the two methods indicate that the spectrum analyzer method is more sensitive to frequency selective fading.

Healthcare industry generates large amounts of complex data about patients, hospital resources, disease management, electronic patient records, and medical devices among others. The availability of these huge amounts of medical data creates a need for powerful mining tools to support health care professionals in diagnosis, treatment and management of HIV/AIDS. Several data mining techniques have been used in management of different data sets. Data mining techniques have been categorized into regression algorithms, segmentation algorithms, association algorithms, sequence analysis algorithms and classification algorithms. In the medical field, there has not been a specific study that has incorporated two or more data mining algorithms hence limiting decision making levels by medical practitioners. This study identified the extent to which K-means algorithm cluster patient characteristics; it has also evaluated the extent to which random forest algorithm can classify the data for informed decision making as well as design a framework to support medical decision making in the treatment of HIV/AIDS related diseases in Kenya. The paper further used random forest classification algorithm to compute proximities between pairs of cases that can be used in clustering, locating outliers or (by scaling) to give interesting views of the data.

Conservation of energy is the biggest need of the hour for developing countries. Smart windows with electrochromic characteristics can be one of the solutions for power shortfall. In this study ionic liquid [BMIM][Br] is successfully synthesized by the reflux method. Ionogels comprising of ionic liquid and polymers (Polyaniline and Polypyrrol) were electrochemically deposited by galvanostatic methods. These films are structurally characterized by XRD and SEM. Concentration of monomer and ionic liquid was changed in order to study the effect on electrochemical and electrochromic properties. The electrochromic character was analyzed by optical studies and colour change was evident at different potentials. To further investigate the electron transport properties, electrical conductivity studies were carried out. In a nutshell different parameters are studied with respect to concentration and temperature, so that best material could be obtained showing high optical contrast and stability. Taking these studies in account an effective electrochromic device can be fabricated.

The Dairy starter culture is referred to carefully selection of desirable microorganisms. Those are intentionally added to milk during conversion into cheese, dahi, yoghurt, and other fermented dairy products to bring about specific changes in the appearance, body and texture, flavor and desired organoleptic characteristics of the final product. The quality of milk itself has an important bearing on the growth of starter organisms. The mastitis milk has abnormal in composition and such milk with high salt concentration does not support the growth of starter culture that leads to production of poor quality of fermented dairy products with week body.. The presence of certain neutralizing substances performed in milk has found to interfere with growth of starters. There was a definite lag in the growth of the starter organisms as well as acid development when neutralizers were added to raw milk samples. This may be due to the bacteriostatic effect of added neutralizers. But discrepancy was seen to the greatest extent in the case of neutralized, mastitis and highly advanced lactation milks and to a lesser degree on the early lactation milk obtained on the 4th and 5th days.

One in six children aged 5 to 14 years old which is about 16 percent of all children in this age group is involved in child labor in developing countries. In the least developed countries, 30 percent of all children are engaged in child labor. In Kenya, the Central Bureau of Statistics reports that 1.9 million children aged 5-17 years are working for pay or family gain. In recognition of the adverse effects of child labour and abuse, international and national efforts have been made to control it. Nevertheless child labour persists as several surveys conducted in Kenya indicate. This paper therefore sought to understand the emerging trends and challenges facing the girl child in urban domestic service in Eldoret town. The paper adopted exploratory research design for an in-depth and holistic understanding of the child labour dynamics. A sample of 253 girls working in the domestic service was used. Purposive as well as convenience sampling were utilized for selecting study participants. Data for the study was collected using un-structured questionnaire, in-depth interviews and observation techniques. A qualitative method was used to analyze data through thematic approach. The paper found that apart from friends, relatives and self being responsible for girl-child entry into domestic child labour, bureaus have been established as an emerging trend where employers get children to work for them. In addition, too much work, misunderstanding between employer and employees; very little pay; delayed payment; working for long hours; and verbal, physical and sexual violence were the major problems and hardships that girl-child workers go through while providing domestic services to their bosses. The study recommends the need for provision of economic opportunities to young girls; promotion of girl child education and sensitisation of parents and guardians on the risks of child labour in domestic service.

The collection of fog water is a simple and sustainable technology to get hold of fresh water for various purposes. In areas where a substantial amount of fog can be obtained, it is feasible to set up a stainless steel as well as black double layer plastic mesh structure for fog water harvesting. The mesh structure is directly exposed to the weather and the fog containing air is pushed through the active mesh surface by the wind. Afterward fog droplets are deposited on the active mesh area which combines to form superior droplets and run down into a gutter to storage by gravity. Fog water harvesting rates show a discrepancy from site to site. The scope of this experimental work is to review fog collection at SCOE, Pune campus and to examine factors of success. This study is to synthesize the understanding of fog water harvesting in the institutional era and to analyze its benefits and boundaries for future development. The rate of fog water harvesting depends on the science of fog physics, chemistry and its starring role in the hydrological cycle. This technology runs on zero energy and zeroes pollution level with cost of the benefit. The collected or treated clear water mainly could be used for different purposes as per requirement. For further development, this technology public as well as government participation is needed.

This article attempts to analyze the changing attributes and role of the Traditional Institution within the framework of new political dispensation in Cameroon since 1990. The Institution came under immense pressure from politicians. The advent of multiparty politics placed the chiefs who were at the apex of the institution in the difficult position: whether they should be partisan, non partisan or stay neutral in an election, the image and importance of the institution as the epitome of the customs and tradition of the people was undermined. The study made use of secondary and primary sources for the collection of data. Concerning the secondary sources, use was made of an extensive literature that offered some general and specific information about the study. After critical analyses of archival data and interviews, tangible evidence emerged as to the fact that Manyu inhabitants at the time be they indigenes or non-indigenes were affected either positively or negatively by the involvement of Manyu chiefs in party politics. To ensure an easy understanding of the study, we adopted a conventional analytical pattern. We used both the chronological and topical approaches. These approaches aimed at chronologically illustrating the evolution of chiefs’ involvement in politics and thematically examining the changes that the division noticed during the period under study. Our findings reveal two central issues: Firstly; the fundamental human rights of subjects was tempered with. Secondly, they lost respect before their subjects, given that some of their subjects doubted their legitimacy as divine rulers or true leaders. This article also argues that despite this, the institution still remains a very important instrument in local governance and nation building in Cameroon. The article ends with a perspective view for a better interplay between traditional institution and the state for the benefit of the division’s development.

The Qur'an is a Muslim holy book using Arabic with the dialect of the Quraish tribe. Textually, the composition or sequence in verses of the Qur'an contains musicality which when combined with the musicality of poetry or Arabic syi'ir (rhyme), both have suitability, especially in conformity with 5 (five) elements of poetry, namely: Sentence, Rhythm, Poems, Imagination, and Deliberate. The opinion of the scholars and the Arabic experts on the existence of poetic aspects in the language of the Qur'an has occurred in contradictory form, some agree and some are not. For those who agree, thought one form of the beauty of the Qur'anic language is a match between the musicality contained in the composition of the verses of the Qur'an with the musicals of the traditional Arab syi'ir (syi'ir multazam), especially in terms of rhythm And his poem. Meanwhile, for the scholars who refuse, they argue, the Qur'an is a divine word, while the syi'ir and the poems are human words, all types or genres of literature are the creation of shamans, imaginers, and fanciers.

Alcoholic abuse remains to be the most common cause of liver cirrhosis with significant morbidity and mortality worldwide. Herbal supplements are being used to prevent damage in excessive alcohol intake and including hepatitis from other causes as hepatoprotective agents. Fig tree is currently being utilized in studies as a potential candidate for hepatoprotection but with limited success. This study determined the hepatoprotective effect of crude aqueous leaf extract of fig tree, Ficus benjamina, on ethanol-induced hepatotoxicity in mice. In this study, fifteen Balb/c mice were assigned to negative control, positive control and treatment groups which received distilled water, Silymarin, and F. benjamina crude aqueous leaf extract respectively on day 0 to day 14. Ethanol-induced hepatotoxicity was done on day 7 to day 14 using ethanol given by oral gavage. Assessment of liver function and histology was done with the use of alanine aminotransferase (ALT) assay and histopathological study respectively. Results showed significant reduction of ALT levels in the treatment (52.40 U/L) and the positive control groups (42.58 U/L) as compared with the negative control group with a mean of 196.88 U/L (P<0.05). The difference between the positive and treatment groups was not significant (P>0.05). The degree of hepatic injury was significantly severe in the negative control group than with the treatment and positive control groups (P<0.05). On the other hand, the degree of hepatic injury showed no significant difference between the positive and treatment groups (P>0.05). Thus, the crude aqueous leaf extract of F. benjamina has hepatoprotective property on ethanol-induced hepatotoxicity in mice, similar to Silymarin. F. benjamina, as an ornamental plant, may be a source of phytochemical with potential pharmaceutical and functional activities.

This paper is a review of the social conflicts of indigenous peoples, especially in North Maluku. The purpose of this review is to find out some factors causing indigenous peoples' social conflicts in North Maluku and to produce alternative solutions as a policy to develop indigenous people's livelihoods. The review resulted in several factors causing social conflicts of indigenous peoples such as; the unclear boundary between the two parties, the customary violations by the forest businessmen, the injustice of the law enforcement officers in solving the problems, the destruction of the indigenous people and the forest community narrow forest, the lack positive contribution of forest management so far to indigenous peoples and forest communities, companies do not involve indigenous peoples and/or forest communities in forest exploitation, destruction of customary buildings as places of worship, deforestation, timber exploitation, while timber by indigenous peoples is sacred wood or abstinence to be felled. Alternative solutions are required by local government such as; policy on legal recognition of indigenous peoples, indigenous peoples' empowerment, implementation of indigenous peoples' aspirations, indigenous peoples' economic development based on local wisdom, and dispute resolution of indigenous peoples through special courts of a holistic nature.

Lake area in Mahakam river basin, which covers 89 719 ha had not only the fuction as a direct life support, but also has a variety of ecological functions such as flood control, prevention of erosion, pollution, and biodiversity of fish control. Lake area will also be difficult to rectify the condition if contaminated, and it took years for recovery. When present, the lake area in Mahakam river basin has experienced degradation bad neighborhood. There are variousefforts made by the Central Government, East Kalimantan province, regency. Kukar and West Kutai regency in the management of thelake, but its still a partial / sector that is less well targeted and unsustainable, due to lack of understanding of weak challenge of integrated lake management strategies. For the purposes of asynergistic co-management and sustainable these weaknessesshould be eliminated, and replaced by management based onmutual understanding, respect, and cooperate with the roadmapagreed upon, namely collaborative management plan. Collaborative management of the lake region requires a long process and the involvement of all stakeholders. Therefore,mapping the area of the lake, the preparation of the managementdirection of the lake, the lake area of spatial development,increased understanding and participation of all stakeholders should continue to be pursued.

The adsorbent power of montmorillonite clay treated with saponins extracted from kernels of Balanites aegyptiaca was evaluated using the terpenes compounds content in the essential oil of Ocimun gratissimun. The properties of formulations based on O. gratissimum essential oil and montmorillonite clay were modified after treatment of clay with saponins. Sabinene, linalool, terpinen-4-ol, α-gurjunene, neo-allo-ocimene, β-caryophyllene, sabinol and β-pinene terpenic compounds contained in essential oil were chosen to follow their adsorption. The kinetics adsorption of essential oil from a solution onto the adsorbents (treated clay and untreated clay) was explored experimentally. Non-linear form of pseudo-second-order model showed a better fit with good correlation coefficient. Intraparticle diffusion model were also used. Non-linear form of Langmuir isotherm model was applied and the data correlated well and the maximum adsorption capacity was found to be 1.07 mol.g-1 with regards to sabinol. Adsorption capacity of montmorillonite clay treated with saponins is greater than that of the untreated clay. The most adsorbed compounds are the oxygenated terpenic compounds. Treatment of clay with saponins increases the persistence of the insecticidal activity of essential oil adsorbed on montmorillonite clay. The mortality of Callosobruchus subinnotatus decreased from 96% to 70% and from 96% to 13.12% for O. gratissimun essential oil adsorbed on saponins-clay and O. gratissimun adsorbed on untreated clay after 42 days respectively. These results can be used in the production of bioinsecticides.

In the following paper I wish to investigate the status of women and their socio-economic conditions during the second civil war. As it was common during that period of time, the war was transferred to the womb of women, and sectarian conflicts during that time and even later usually involved “mudding” the blood of future generations of one sect. Therefore, I wish to examine whether this was the case in Lebanon. In order to do so, I will divide my paper into five sections. The first section of the paper will discuss the socio-economic background of the working class families of different sects in Lebanon. The second section of the paper will investigate the other means that were used during the war to weaken the Other, i.e. the focus will be directed at unarmed forms of violence. The third part of the paper will discuss the effects of the war, and more specifically it will focus on how women perceived, experienced, and the extent to which they were affected by the war. The fourth section will attempt to draw a comparative analysis in which the situation of women in Syria, Lebanon and Palestine, have been affected similarly during different conflicts at different locations and periods. The last part of the paper will attempt to draw some conclusions about the eruption of the war and whether its consequences still cause distress to Lebanese women today.

The importance of proper Water Resource Management with greater emphasis on ensuring sustainability, quality, accountability and community participation has become imminent as water resources increasingly become scarce (Harvey et al, 2007). Water resources management in Tanzania is governed under the National Water Policy of 2002 and Water Resources Management Act No.11 of year 2009. Other related legislations include Environmental Management Act No. 20 of year 2004, Forest Policy and Forest Act No. 14 of year 2002 and Water Supply Act No.12 of year 2009 among others. However the mechanisms, processes, and institutions through which all stakeholders articulate their priorities, exercise their legal rights, meet their obligations and mediate their differences is still missing. This study employed descriptive exploratory research design. Data collection was done by the use of both structured and semi structured interview to respondents who were both purpose and simple randomly selected, observation and focus group discussion. Review of reports from Districts and Basin offices and internet to access relevant secondary information was done. Results show that WUAs, LGAs and WSSAs lack relevant understanding, capacities, management and law enforcement as result water management generally remains non participatory, inefficient and expensive and increased water user conflicts in Kisangata and Ilonga WUAs of Mkondoa sub catchment, Morogoro region. The study propose participatory approaches best practices on water resource management at local level for embracement of Community- Based Water Resource Management as the only option of managing sub catchment water resources and reduce water related conflicts among water users. Awareness creation on policy and establishment of alternative economic activities like horticulture, bee keeping and poultry is significant to give relief to land.

The study aimed to determine the effect of heavy metal pollution on 7-ethoxyresorufin-O-diethylase (EROD) enzyme activity in carp (Cyprinus carpio) and tilapia (Oreochromis niloticus). The samples were taken by purposive random sampling technique. The treatment site was the downstream part of the Kaligarang River, Semarang, Indonesia, which contaminated byheavy metals (concentration of Cd 0.007 ppm, Pb 0.010 ppm, and Hg 0.0006 ppm). A clean reference site in Nyatnyono Village, Ungaran was used as the control site with the heavy metal content of 0 ppm. The EROD activities in carp and tilapia were significantly decreased after Cd, Pb, and Hg exposure. The results showed that the average value of liver EROD activity in carp fish control group amounted to 1.77 ± 0.23µmol/min/mg protein and the treatment group was 0.49 ± 0.24µmol/min/mg protein. Whereas in control group of tilapia fish, EROD activity was equal to 2.08 ± 0.47µmol/min/mg protein and the treatment group was 0.49 ± 0.40µmol/min/mg protein. The results demonstrated that metallothionein was a specific heavy metals biomarker, whereas EROD activity ishighly sensitive to extremely low concentrations of theselected pollutants.In conclusion, the use of multiple biomarkers is recommended to monitor the heavy metal pollutants in the river environment.

This study aimed to analyze the bank rating in terms of differences the financial performance between the Regional Development Banks and Non-Foreign Exchange Commercial Banks. It is consist of capital adequacy, asset quality, profitability, Return On Asset (ROA), Return on Equity (ROE) Net Interest Margin (NIM) and Liquidity (Loan to Deposit Ratio). The fulfillment of capital adequacy and asset quality of the bank groups did not differed significantly, while in terms of profitability and liquidity there are significant differences. The earning difference is more likely due to the Regional Development Bank's sources of funds for the implementation of the Local Government Cash Holder function as the Provincial Government and District / City. The difference of liquidity are showed by the performance of Regional Development Banks and the Non-Foreign Exchange Commercial Banks in lending/financing, whereas the two groups of banks on average are still relatively low in lending.

The title of the research was Frame and Blame: An Analysis of How Local Newspapers Framed the Conflict Between Conventional and Technological Application-Based Transportation Service in Medan. Waspada Daily Newspaper as local newspapers more frequently put a human face on the issue, while national papers more frequently framed it a moral wrong. The objective of the research was to find out how the newspaper constructs the news about this conflict and how it explains the conflict as part of its social responsibility in its news product. The research used qualitative method with paradigm constructivism which considers the subject, Waspada Daily News, as the central factor in the communicative activity and social relationsand as the function of control toward social facts which occur in society (the conflict between motor pedicab drivers and go-jek riders). Framing analysis is a descriptive textual analysis of media used to find out how news is understood and framed by media. The research used Gamson and Modegliani framing model analysis, based on constructivism approach in order to find out the representation of media. The theory of Berger and Luckman Reality Construction was used to explain social reality constructed through the process of externalization, objectivity, and internalization. The result of the research showed that 1) Waspada Daily Newspaper prioritized the conflict because the conflict was the effect of the lack of income of motor pedicab driver, and also because there was no regulation on the transportation/operation of Go-Jek online, 2) Waspada Daily News exposed the conflict in the front page in four days consecutively which indicated that there were attention and seriousness of moral evaluations.

Communication strategy on family planning campaign is the interpretation on knowledge, attitude and practice theory (KAP theory) that commonly used in many health campaign programs in developing countries and advance countries in the world. This theory can also be applied for other programs such as agriculture, family planning, commercial, and society capacity building. The aims of this research are to described and analyzed communication strategy on family planning campaign by the field officer for family planning campaign, and also to find out all factors that can be the obstacle on family planning program in Sumatera Utara province, especially in Langkat District. The long term goal of this research is to find out the best method that can be done by the government in order to get people’s support. It can only be achieved if the program are transparant, clearly stated and on the perfect target. The population of the research are the field officer for family planning campaign (10 person) and also the citizen of Langkat District (10 person plus their husband/wife). All informants were being selected by purposive sampling technique. Observation, interview and Focus Group Discussion were also being held in order to get best result. Several results were shown: It showed that the better productive age couples receive information about family planning, the use of contraception (especially using injection and implant methods) among productive age couples is increasing. Biggest problem in Langkat District is that many of the family planning acceptors using short therm contraception method such as pill, condom and injection rather than long term contraception method such as IUD, implant or vasectomy/tubectomy. BKKBN (National Family Planning Coordinating Body) in Langkat District still need to improve many aspects on doing communication strategy on family planning campaign by the field officer for family planning campaign, especially in the low income productive age couples where the birth rate number is still high. Another thing they should do is to raising the number of supply for the contraception products such as pills and IUD.

Security is a major concern for everyone, be it individuals or organizations. As the nature of information systems is becoming distributed, securing them is becoming difficult as well. New applications are developed by researchers and developers to counter security issues but as soon as the application is released new attacks are formed to bypass the application. Kerberos is an authentication protocol which helps in to verify and validate a user to a server. As it is a widely used protocol minimizing or preventing the password attack is important. In this research we have analyzed the Kerberos protocol and suggested some ideas which can be considered while updating Kerberos to prevent the password attack. In the proposed solution we are suggesting to use password and biometric technique while registering on the network to enjoy the services and a combination of cryptography and steganography technique while communicating back to the user.

Effect of heat treatment on different properties of Titanium dioxide(TiO2) nanocrystal is being reported. Nanocrystalline TiO2 was synthesized via chemical precipitation methods using TiCl3 as starting material with two types of precipitants: NaOH and NH4OH. The effect of calcination temperatures (300,500 and 900˚C) on the crystalline structure, phase formation and morphology of synthesized TiO2 were investigated by Xray diffraction (XRD) and Scanning electron microscope (SEM). For precipitation method using TiCl3 + NaOH, the structure and phase determination using XRD analysis were confirmed the small crystallite size in the range of 11nm to 31nm with rutile phase. In the case of TiCl3 + NH4OH, phase transformation from anatase to rutile was clearly observed at annealing temperature of 900˚C. The SEM range revealed that almost of the nanocrystals are in spherical shape and effect of heat treatment on particle size was observed. According to the results, pH does not influence the TiO2 morphology but the agglomeration becomes higher when the temperature calcination is increased.

The essence of restorative justice in the settlement of household violence is very important as bridge for peace of the parties, to restoring good relations between the perpetrator and victim, both the direct and indirect victim (the family of victim). The type of research is socio-legal research with the normative law method (doctrinal research). The results shows that the implementation of restorative justice of adjudication on household violence cases can be applied, although there is no legal arrangement. The judge may apply in its judgment based on the fact that the judge cannot refuse a case because of a law that does not exist or it is unclear. Judges are required to explore the values that live within society to discover the law. It can be concluded that restorative justice has been acknowledged by its existence in the adjudication as the purpose of punishment. Similar perceptions are required for law enforcers concern the concept of restorative justice as the purpose of punishment.

A new study in Kenya has spatially quantified the paradigm shift in the current and future malaria vectors ecology by use of BIOCLIM True or False model with IPCC HADCM3 projected future climate under A2a scenario. The study was designed to correlate the effect of climate change as an explanatory variable, among other factors, on malaria vectors distribution in Kenya. There has been reported malaria cases in new Counties that were never malaria endemic zones, thus the study seeks to research on ecological changes that can be as a result of changing environmental factors to support malaria vectors to thrive in new areas. Predictive modeling was done to investigate the spatial-temporal vector distribution under different IPCC future climate projections. The period from 1950 – 2000 was treated as the current climate scenario to explain where malaria vectors are existing as per vector spatial presence data and the prediction of the ecological niches where the vectors would also be found to thrive. Ecological Niche Modeling demonstrated significant alteration in suitability of malaria vector habitats in Kenya from the current ecological zones by the years 2020, 2050 and 2080. Most of the current malaria ecological niches were found to remain suitable while others turned out to be unsuitable after projection although new malaria hotspots were found to emerge. Prediction by the year 2050 demonstrated an alarming expansion of suitable malaria ecologies. By 2080 the predictions showed that the suitable ecologies will start to revert similar to the earlier suitability as in the current climate. Therefore, climate change in Kenya will adversely affect the environment at an alarming rate by 2050, but beyond that there will be a level of stabilization, where further change will trigger reversal to the past climate. This change in unsuitable to suitable malaria habitats can negatively affect the national effort to fight malaria under the ongoing towards zero campaign if strategic planning overlooks the possible effect of climate change among other factors on future dynamics of malaria distribution in Kenya.
