Aging is a post-harvest storage process to improve rice's quality and functional properties. Rice that has been through the aging process, especially in color, has different sensory properties from fresh rice. It also affects flavor, viscosity, hardness, cohesiveness, adhesiveness, and micro-content after cooking. Such changes are due to enzymatic and non-enzymatic reactions, microorganism presence, and interactions between molecules and the environment. The aging process involves natural aging and artificial aging. Natural aging is the time required for rice post-harvest storage for about 3-4 months. Meanwhile, artificial aging has shorter storage times, also called accelerated aging. It affects rice's chemical, physical, and sensory characteristics that change during aging.

A healthy atmosphere leads to a healthy and happy environment. Now a day's population is increasing more rapidly due to which waste amount is also increasing day by day. Management of Waste is the main problem now a day's. A well-monitored system is crucial to make the environmental pollution-free with the latest technology internet of things (IoT) based smart management system. This can even reduce the monitoring time. This system would be helpful even in reducing garbage production by using IoT based system negligence for regular checking of a dustbin. It is even possible a dustbin might get filled early and need attention instead of an extended checking routine period. That is why this system is much better than the current existing system. However, unfortunately, it has been difficult for many countries to implement these solutions due to financial and many other problems. That is why we focused on developing IoT based smart management system for developing countries such as Pakistan. This system includes proper collection and recycling of waste into new useful products and energy resources by using minimum resources. This IoT-based smart management system includes Wireless Sensor Network, Nodemcu while the Microcontroller communicates the sensor system.

Seafarer's job is mostly long durational, contact base, and tiring in nature that is correlated with their stress. We are exploring the level of stress among the Asian sea-farers with the associated personal and professional factors in the COVID-19 pandemic using an online-based cross-sectional survey (n=95). The 5-Likert scale used in the stress scale and a combination of all the stressors construct the stress score where simple linear regression analysis and Pearson correlation have applied. Most of the sea-farers are young aged (46.3%), married (58.9%), and ranked as deck officer (55.8%). Only 28.4% of seafarers have more than ten years of experience. Stress level among them is comparatively high (µ, SD; 75.13, 16.192) and pertains among 77% seamen. We also found that the age of the seafarers is positively correlated with the sea-going experience and stress score while negatively related to the port call frequency and extension of the contract. We also found a statistically negative correlation of sea-going experiences and extension of the contract. Regression analysis explains stress level 20.1% through the effect of pandemic and sea-farers age at p<0.05. Therefore, more concentration on the sea-farers stress has suggested during critical conditions like pandemics

The photocatalytic activity of titania from nanotubes (TiNT) to eliminate phenol was investigated. Titania nanotubes were prepared using a hydrothermal method, followed by an acid washing process and calcination at various temperatures. The as-prepared titania nanotubes were then characterized using various methods: field emission scanning electron microscopy (FE-SEM), X–ray diffraction (XRD), UV–vis Diffuse Reflectance Spectroscopy (DRS) and Brunauer-Emmett-Teller (BET) analysis. The experimental results showed that the calcination temperature strongly influenced several TiNT properties that determine the phenol photodegradation activity of TiNT. As the calcination temperature increased, the nanotube morphology became more rigid and defective and even became damaged when the temperature was excessively high. The crystallinity and crystal size of TiNT increased however, the surface area decreased as the calcination temperature increased. Interestingly, the TiNT band gap was independent of the calcination process. The TiNT sample calcined at 700 °C showed the best performance for phenol photodegradation achieving 54% of phenol elimination due to its high level of titania anatase while maintaining the nanotube structure. At a higher calcination temperature (800 °C), the photocatalytic activity of TiNT was very low due to the formation of the rutile phase and the absence of the nanotube structure.

Powder metallurgy technique was used to develop carbon fiber reinforced aluminium composites. By enhancing the wettability between CF and Al matrix through surface coating with a thin layer of nano Cu by the electroless plating technique. Two series of samples are prepared from 0,5,10,15 wt% CF/Al composites. For comparison, one of them was prepared from uncoated sample CF and the other group from Cu-coated ones. Both groups are fabricated by a uniaxial hot-pressing technique under 700 MPa and 500℃. The effects of reinforcement weight fraction and reinforcement coating on microstructure, density, electrical resistivity, thermal conductivity and coefficient of thermal expansion were studied. The results revealed that the density and CTE were decreased while both electrical and thermal conductivities were improved by increasing CF percent. Harmful AL4C3 was absent in all produced composites and no intermediate compounds were detected in coated composites. The Cu coating process was an effective way to improve the interfacial structure. The values of electrical and thermal conductivities of coated composites were higher than those of the uncoated composites, and CTE was reduced to 11.98 k^ (-1) at 15 wt.% Cu-coated CF/Al composite, which is suitable for semiconductor in electronic packaging applications...

Recent development and increase in locally manufactured product demands access to anthropometric data for better design usability of products. Therefore, local designers and manufacturers must have an available database to design ergonomically appropriate product for consumers. Estimation of various body measurements is important for designing work not only in the industrial but also in-service sectors. The purpose of this study was to explore the value of various anthropometric measurements for predicting stature. The anthropometric measurements used are Buttock Height, Elbow Wrist Height Standing, Shoulder Height, Upper Arm Length, Lower Arm Length, Eye Height Standing, Full Leg Length, Lower Leg Length, Buttock Knee Length and Eye Height Sitting. This study is an attempt to develop a model that will predict the anthropometric measurements of the young men between age 18 to 30 in the province of Khyber Pakhtunkhwa, Pakistan. This study is important as there is very little literature available for designing work in various medium and small industries located throughout the province, and it will certainly benefit the socio-economic scenario. Multiple regression modeling was used in the prediction of stature based on ten independent variables. In this study it was observed that there is a strong correlation between the stature and other body dimensions, and models can be developed to predict various anthropometric measurements.

LTE supports different transmission modes such as: Single Input Single Output (SISO), Transmission diversity (TxD) and Multiple Input Multiple Output (MIMO). TxD aims at improving the signal strength at the receiver by using two or more transmit antennas while MIMO techniques are used to increase the throughput according to the number of antennas used. Coordinated Multipoint (CoMP) techniques reduce interference and improve signal strength. Homogeneous networks consist entirely of macrocells while heterogeneous networks (HetNets) have both macrocells and femtocells. HetNets are used to meet increased mobile traffic demands by providing low power nodes closer to the user equipment. This paper reviews popular transmission modes and investigates their performance in both homogeneous and heterogenous CoMP networks. Simulation of the different transmission modes is carried out and results show that CLSM is the best transmission mode to use in in homogeneous networks, and that CLSM and OLSM perform equally well in HetNets, Additionally, HetNets were found to provide significant throughput gains over homogeneous networks.

Fractional Frequency Re-use (FFR) is a popular technique for controlling inter-cell interference in OFDMA cellular networks. FFR involves dividing each cell into inner and outer layers, with different frequency re-use ratios for each layer. Important design parameters in FFR are the signal-to-interference-plus-noise ratio (SINR) threshold, Γ_th, and the frequency allocation ratio, β_FR. In conventional FFR schemes, Γ_th and β_FR are fixed and do not vary with cell conditions. A dynamic FFR scheme is developed where the optimal SINR threshold is determined using Otsu’s method, a digital image processing technique. The optimal SINR threshold is calculated based on periodic SINR values in the cells, and β_FR then set proportionately to the number of users in each layer. The designed system is evaluated through system-level simulations is found to outperform conventional FFR in terms of both throughput and fairness.

Different fractional frequency reuse (FFR) schemes have been proposed in literature, with the most common being the two-layer scheme. In this scheme, the cell is divided into an inner region and an outer region. Different frequency sub-bands are used in each region, with the inner region typically having a reuse-1 scheme and the outer region a reuse-3 scheme. This has been shown to be effective in reducing inter-cell interference and subsequently improving reception for the cell edge users. This paper investigates the effect of using different schedulers in the inner and outer regions of a two-layer FFR scheme. The schedulers chosen for evaluation are the proportional fair scheduler and the round robin scheduler. Different scheduler combinations are investigated for various values of β_FR to evaluate performance trends. Metrics considered for evaluation are the mean, peak and edge throughput, as well as fairness. Simulation results clearly show that the proportional fair scheduler outperforms the round robin scheduler in both throughput and fairness. We also conclude that optimal FFR performance can only be obtained by trading between throughput (spectral efficiency) and fairness, regardless of any scheduler combination considered.

The requisite of trust in cloud is well justified because of architecture of the technology but the ever increasing data leakage cases have turned it into necessity. Cloud services are delivered from data centers to cloud consumers through cloud providers. It is required to evaluate the trust level of Cloud Providers as they are one of the key elements in the cloud services deliver aspect. The consumers need to evaluate the trust level of provider before enrolling for cloud services but they are not much aware about the procedure and evaluation facets. The main objective of this paper is to support the consumers in evaluating the trust level of the provider. As it seems that complete IT industry is regulated through standards & Certifications, so it is used as main criteria of trust evaluation. An OTF (Overall Trust Factor) is calculated on the basis of customer’s preferred components and certifications attainment status of provider is assessed in respect to these components for trust evaluation.

The present study aimed to measure the prevalence of psychological problems among Saudi female students in late adolescence; specifically, the problems were anxiety, phobias, rage outbursts, isolation. The research sample consisted of (140) female students. The results of the study showed there was prevalence of psychological problems among Saudi female students which was reported at an average level except anxiety. In addition, the major variations were correlated with anxiety, rage outbursts in favor of the variable of the working mother, whereas there were no significant differences correlated with phobias, and isolation. All these problems, therefore, are due to Saudi female students in late adolescence because of the various status of working and non-working mothers. Additionally, there were not any statistically significant differences for those psychological problems among Saudi female students within the late adolescence. Furthermore, for those psychological problems among Saudi female students in the late adolescence, there were no statistically significant differences that can be attributed to the various educational level of the mother whether pre-university level, university level, or above.

The present paper deals with laser induced longitudinal wave through the shock driver. Flat glass coated with thin metal is considered as shock driver. Three different thickness of metal is used as boundary of shock driver. This boundary is very important for producing efficient shock wave for many bio-engineering applications. In low irradiation laser intensity, the absorbed laser energy is converted to the thermal energy and consequently, local thermal expansion occur near the impact point. This paper shows that the significant temperature rise generates the longitudinal wave with very high amplitude in order of 107 inside the shock driver due to the thermo-elastic phenomena. It was found that lowest nano-meter thickness of metal can generate high amplitude longitudinal wave. The rise time comes from the lowest nano-meter thickness of metal is very shorter than others. The longitudinal wave response, from the lowest thickness of metal, is found very promptly, in the order of about 20 ps. From this phenomenon it can be understand that the longitudinal wave which comes from lowest boundary of shock driver can transfers momentum to generate effective shock wave.

The Current research presents a numerical study of the Non-Newtonian fluid flow through forward – backward step tapered channel in two dimensions. The Galerkin finite element scheme with the least square residuals is adopted for the discretization of the differentials comprising the continuity and brinkman transport momentum equation in cartesian coordinates. The flow attributes of shear thinning fluid for index 0.90 and 0.95 and shear thickening fluid for index 1.1 and 1.2 through tapered step channel is the centre of attention in the recent work. The numerical result at Re = 1000 for fluid index n = 0.90 shows formation of vortex behind tapered step that covers around 40% of the downstream while on the other hand fluid with n = 0.95 occupies 50% region of the computational field. The flow behavior of shear thickening fluids is significantly different since the rate of generation of eddies is much higher than the shear thinning fluids. The fluid with index 1.1 and 1.2, both produces massive recirculation zone which grabs the whole solution domain of the problem and it brings higher vortex intensity when fluid inertia hits its peak. The gradual enhancement in the size of eddies for all the four cases are presented through streamline patterns at various fluid inertia (1 < Re < 1000) for better visualization of flow characteristics. Also, the graphs of vortex length and vortex intensity are provided as the function of Reynolds number to monitor the drastic changes in under considered quantities. The employment of Least Square Galerkin Finite Element Method (LSGFEM) for the numerical solution of present study is found to be in good agreement with available data in literature.

Web-based social networking services (SNS) allow people to connect across political and geographic boundaries who share interests and activities. Online social network services (SNSs) as Twitter have recently been highlighted as a means of understanding the implicit interest of users from the abundance of online information. This research aims at tracking Twitter users' interests, which has become a matter of concern for all, from the government of a nation to the businesspersons from politicians to celebrities. Existing approaches for understanding user intentions and interests mainly focus on finding the interest depending on the tweets and whom they follow. The level of interest of the user does not necessarily depend on who they are following and what they tweet each time. This may result in inaccuracy in predicting the interest of users. This research outlines the topics of interest derivation by tracking the Twitter micro-blogging considering other degrees (such as time, activeness of the user) that affect Twitter user's interest. It also provides a framework to set the interest rate and rank the user using the proposed architecture. Experimental results reveal that the topics of interest deduced by the proposed method outperforms those topics inferred by models (Labeled LDA) on tweets. This research certainly speculates the user's interest in Twitter correctly; more studies are needed to speculate the user's interest providing the Twitter user's geographical impact.

The use of polystyrene beads in concrete applications has been limited due to its perceived low strength properties. Most of the conclusions in this regard were drawn from studies conducted using trial mix method. Obtaining a reliable mix ratio from this method is relatively more expensive, detailed and time consuming due to the large number of trial mixes required to obtaining a reliable result. On the other hand, several studies have shown that optimization of strength properties of concrete to suit different needs using mathematical models is more reliable and economical. While some optimization models have successfully predicted the various strength properties of polystyrene concrete, only very few studies or none have applied this technique in predicting the tensile strength of polystyrene concrete. The tensile strength test is an important test that determines the vulnerability of concrete to tensile cracking due to the weight of the structural load. Water, sand, coarse aggregates, expanded polystyrene beads, and ordinary Portland cement are the materials used for this study. All the materials were batched according to their weight, except for polystyrene and coarse aggregates which were batched in volume after mixing them together. The polystyrene partial replacement level was considered at 12% of the coarse aggregate volume. The model equation adopted for this study was based on Scheffe’s {4, 2} simplex lattice design for both Pseudo component and component proportional models. The actual model was developed from the 28th-day test result. The Mathlab and Minitab 16 software was used in this study to generate the actual mix ratios based on the model result. The results obtained showed that both Pseudo component and component proportional models both produced an average split tensile strength of about 5.10N/mm2. This implied that the results of this study produced a split tensile strength result that varied between 18% - 19% of its compressive strength result. This showed that the materials and the mix ratios optimized in this study are suitable as building blocks for residential low rising buildings and as partition slaps for high rising buildings. The lightweight property makes it highly suitable for large scale application in high rising structures as internal partition slaps only.

Universities in most countries of the world seek to obtain accreditation, whether "institutional or programmatic” at national and international levels, as this impacts not only In increasing graduate's skills but also in strengthening university's competition in local and global markets. This is achieved through the educational programs and institutions quality, which are achieved by following standards set by specialized bodies called "accreditation bodies" which are considered governmental or non-governmental oversight and mandatory bodies working to develop evaluation standards and conduct evaluations and visits to the institution or program to assess if they meet these standards or not, It is entitled to grant formal accreditation and sometimes a license to operate after the successful completion of the application of the standards, These standards differ from one body to another according to the different founders and their goals. Among international interior design programs accreditation bodies: Council for Interior Design Accreditation CIDA, the Middle States Commission for Higher Education MSCHE, the National Association of Schools of Art and Design (NASAD), and others…, They accredit interior design programs in various places around the world, help in enhancing profession by coordinating educational and professional standards that play an important role in influencing an interior designer attitude Whether technically, artistically, culturally, historically or practically. Interior design graduate attitude differs from a university to another according to different accreditation body standards for each program. Therefore each body has a specific vision and thinking, so the multiplicity of interior design program accreditation bodies and their spread in different places in the world may disseminate different cultures or may affect on graduate’s attitude; it may correspond to the environment he lives or differs with it in some conditions such as "social, traditional, technological, environmental and human " conditions. Hence, the research problem is confined to the difference occurs between interior design graduates (future designers) as a result of adherence to the standards of program accreditation from different institutions around the world and the difference in visions between those bodies and the extent of their impact on the designers attributes in local environments, so, Is it necessary for the accreditation body to be "national" to emphasize features that an interior designer must possess or reliance on international accreditation body in accrediting local programs that may achieve competence in the scientific and technological capabilities of local programs graduates?. The research aims to identify the discrepancy in the attitude of the graduate in both programs that are accredited by national and international bodies and to monitor the standards of national and international accreditation bodies to know the scientific, technological, cultural, artistic, and professional controls that interior designer must possess, Research methodology is based on the descriptive, analytical and survey approach.

Food has a high level of moisture so that it is damaged easily. Preservation is an effort to improve a food's shelf life. Salting has been one of the oldest known food preservation. The simple process usually leads to this preservation by the community naturally. It can be done conventionally and naturally. Salting preservation is by reducing the level of water so that bacteria cannot grow up and develop. The osmotic properties of high salt can break down the microbial cell membrane, and its hygroscopic properties can interfere with proteolytic enzyme activity and dissociated Cl ions. Salting is not a single curing process, so other treatments such as desiccation or boiling are usually followed. Salt also plays a vital role in developing specific tastes, textures, and aromas. The salting process is divided into a wet-dry and wet-dry combination, and a curing process is also carried out. The NaCl salt is in the form of a crystal or solution. In the curing process, nitrate and nitrite salts are used. This paper is intended to review the salt mechanism for the application of food preservation. It is widely used in food products such as salted cod, kimchi, sauerkraut, beef, milk, and cheese. In certain foods, the lactic acid bacteria fermentation phase begins with salt added. The effects on food are flavor, water-holding capacity, protein characteristics, and lipid oxidation.

Pruning is the cutting of young branches and growing on the main trunk of the tree. This activity aims to increase the free height of branches and reduce the main branches of the trunk. Pruning branches or twigs that are not needed makes the nutrition of the tree more concentrated for tree growth (main trunk and canopy or fruit). The pruning process requires cutting tools. One of the cutting tools that can be used is a saw. To make the pruning process easier, a saw can be applied from the ground or without climbing trees. Therefore it is necessary to design telescopic saws that can be used to prune. The design of a telescopic saw includes a saw blade, a saw blade, a connector for the saw frame, a telescopic rod, and a connector between the handles. The results showed that the telescopic saws from the design can be used to trim the palm fronds and teak branches properly. The dimensions are 645 cm long and 15 cm wide. The cutting rate of teak tree branches is 43.47 mm2/s on the tree and 77.89 mm2/s on the ground. The rate of cutting of oil palm fronds is 160.18 mm2/s in trees and 226.26 mm2/s in the ground. Cutting rates on the ground are faster than on trees. The rate of cutting of oil palm fronds is faster than teak branches. The effectiveness of cutting 59.14% teak branches and palm fronds 74.24%.

This study analyzes the effect of education level and socio-economic characteristics on household poverty status in the Riau Islands Province. By utilizing the Multinomial logit model, this study analyses the factor that influences household poverty incidence. The poverty levels are divided into three categories: poor households, near-poor households, and non-poor households, based on the definition of the Indonesian Central Bureau of Statistics poverty lines using the expenditure approach. Using the Indonesia National Economic and Social Survey (Susenas) 2018 data, the findings show that the probability of being poor in the Riau Islands Province is influenced mainly by the household head's education, household size, and employment status. Aside from providing training to household heads who do not have primary education through a vocational training center, the government should also increase the number of vocational high schools and adjust the curriculum to the industrial/labor market needs.

Higher education institutions are currently facing a competitive environment such as the increase in employers’ demand and the challenges from Industry 4.0. Due to this situation, the industry and society are expecting graduates to have extensive knowledge with critical thinking skills and good personality. Therefore, higher education institutions must ensure that students overcome the challenges in this competitive environment. In order to achieve this, student performance needs to be analysed systematically by identifying the students’ deficiencies and advantages. This paper focused on the student performance analysis per year by using fuzzy logic evaluation methods. Fuzzy logic was developed with selected attributes of student assessment performance by using MATLAB software. In this method, students’ characteristics through assessment (knowledge, problem-solving skill, etc.) were the weighting factors for evaluating students’ academic performance and their personality development. Then, an expert system using fuzzy logic based on the Mamdani technique was designed and tested on real students’ mark sample. The results of the fuzzy expert system and conventional method were later compared. Based on the results, the reasons behind the deficiencies of students were identified, whether they were weak in academic or in personality development. This result could assist higher education institutions in determining the appropriate lectures, activities, and assessment for students, and also improve the human capital needs by the industry.

Albeit there are many frameworks for assessing organizations’ readiness to protect critical infrastructure from cyber threats, in the context of their application to specific organizations, such as the military, it requires significant adjustments or formulating more straightforward frameworks. The purpose of this study is to examine the effectiveness of the application of Sixware cybersecurity (SWCS) framework developed for sub-organizations in the Ministry of Defense and the Indonesian military. We used mix-method-convergent by analyzing interview data with three organizational unit leaders and distributing questionnaires to three organizational units with 70 respondents in the Indonesian Ministry of Defense. We found that the SWCS framework was practical and had good portability. Another finding is that applying the SWCS framework is more suitable for assessing cyber defense readiness in uniform organizations or communities in the field of IT and network management or cybersecurity operations. These findings also encourage further research to prove whether the SWCS framework is also appropriate for respondents in different organizations or non-IT communities.

With the increasing population of Semarang City, the need for potable water increases every year. To ensure the availability of sufficient potable water for the people of Semarang, a water distribution system in West Semarang is being built that uses water from the Jatibarang Reservoir. The current plan is to use a pump system to deliver potable water to people from the Water Treatment Plant (WTP). Previously, this flow is also used for Micro Hydro Power Plant which generates electricity of 0.9 MW. Actually, from the Jatibarang Reservoir it can be flowed directly to the Water Treatment Plant (WTP) using a gravity system. This gravity flow system can save costs related to pump water to Water Treatment Plant (WTP), but with this gravity system it is not streamed to the Micro Hydro Power Plant so that it does not generate electricity. From these two alternatives, the pump system has higher head loss than the gravity system. The head loss of pump system is 44.87 m while the gravity system is only 11.97 m. In addition to head loss, the economic feasibility is also analyzed until 2039 (for 20 years) and the results show that both are still feasible to build.With the pump system having a Payback Period (PP) value of 5 years, the Return of Investment (ROI) value of this project is 192.18% (> 100%), and the Internal Rate of Return (IRR) value is 30.98% that this IRR value is greater than the current average interest rate of 10 well-known banks in Indonesia, which is 9.594%. In addition, the value of the Benefit-Cost Ratio (BCR) and the Profitability Index (PI) has a value of more than 1, namely 2.922 and 3.216. In addition, the Net Present Value (NPV) value is positive, which is IDR 737,758,404,913.88. The project is not feasible if there is a decrease in the value of income by 69 % from the original value of the benefit from electricity and water service or a change in the effective interest rate to 20%. With the gravity system, it has a Payback period (PP) of 3 years. The Return of Investment (ROI) value of this project is 380.47% > 100%, the Internal Rate of Return (IRR) value is 47.81%, which is also greater than the current average interest rate of 10 well-known banks in Indonesia. Indonesia, amounting to 9.594%. In addition, the value of the Benefit-Cost Ratio (BCR) and Profitability Index (PI) also has a value of more than 1, namely 4.805 and 4.998.
