Pipe failure in a rising main pipeline of a pumping station in a sensitive tourist area raised the need for a comprehensive water hammer analysis to find the causes and address protection measures. Being a low head pumping station, only a check valve has been installed to protect the system from water hammer effects. Calculations and computer modelling confirmed that immediately after an uncontrolled pump stop or power failure, the negative pressure wave starts propagating along the pipeline from the pumping station to the discharge manhole. The minimum pressure envelope intersects the rising main (pipeline), creating a vacuum on the pipeline in almost its full length. Without water hammer protection measures, the vacuum on the pipeline would be one of the main causes of the pipe failure. This study confirmed the need for water hammer analysis and consideration of protection measures even in rising mains of low head pumping stations to eliminate the consequences of such phenomenon.

Next to food, shelter is one of the three essential human needs and the second most significant survival of human. It is the most complex of the three essential man’s needs since majority of human activities are accommodates by shelter. Housing demand is associated with increasing rate of urbanization in most cities of the world including Nigeria, which has become a common feature of contemporary societies. This study seeks to review the source of finance and issues related to financing the property development in Nigeria. To achieved the above aim, the objectives were drowned as; To identify the source of finance for property development in Nigeria. To explore the problem associated with property development in the study area. The study adopted a secondary source of data collection as methodology, where various journals/articles were reviewed. Real estate development finance sources can either be internal or external. When the fund was generated internally in the form of estate income is known as internal source, while the mortgage source can be categorized as external. Real estate development in Nigeria has been faced a variety of difficulties. These issues can be two-faced both the commercial banks as well as real estate developers which make it difficult in funding real estate. These problems make real estate lending risky, as it is vulnerable to capital loss and projected interest income, and therefore not attractive to commercial banks, thus restricting the development of the real estate. The FMBN (Federal Mortgage Bank) should focus solely to the wholesale functions as its designated to, and operate in the secondary mortgage sector through providing PMIs, housing finance, and construction companies/associations in the country with mortgage banking services. This would be achieved by acquiring mortgage loan blocks already issued via the main housing finance firm/mortgage institution at the primary sector.

AConcrete-filled steel tube (CFST) structure has been widely used in civil engineering structures as it offers numerous structural benefits.The (CFST) columns’ behavior has been investigated intensively against axial and lateral impact loading. However, there is a lack of knowledge on the response of (CFST) columns when filled with different types of concrete. Therefore, to close this gap, experimental and numerical studies were carried out to investigate the performance of CFST members filled with four different types of concrete under the effect of lateral impact load. The concrete types were normal concrete, steel fiber concrete, and propylene fiber concrete all with average cubic strength of Fcu=45 N/mm2, except the last one was high strength concrete with Fcu=70 N/mm2. In high-loaded members, the available standard tubes’ sizes available in domestic market will not cover the required design size, hence emerged the need to fabricate the required size of pipe by welding. Consequently, the effect of using seam weld pipe instead of seamless pipe on the response of (CFST) under impact load was investigated in this study. Accordingly, eight specimens were tested divided into two groups, four specimens for each. The first group is fabricated from a seam weld pipe and the other group from seamless pipe. The parameters studied were types of concrete and steel pipe.The failure mode and local damages of the specimens were thoroughly investigated. A finite element analysis (FEA) model was then performed to simulate the behavior of (CFST) members against lateral impact loading and validated with the corresponding experimental results. Wide range analyses of the (CFST) columns response against lateral impact loading were then carried out using the validated FE models to examine the deformation and the energy dissipation of each concrete type. The main findings are as follows: (1) The seam weld specimens have an almost equivalent lateral impact resistance as seamless CFST counterparts. (2) The lowest value for the total impact energy and maximum dynamic displacement were recorded for the specimens filled with polypropylene concrete specimens. While the maximum recovery energy was observed for the same specimens. (3) Nearly the same value for the total impact energy and maximum dynamic displacement were recorded for the specimens filled with ordinary concrete and high strength concrete.

Muhammadiyah 4 Vocational School Jakarta is one of the vocational high schools in Jakarta that has implemented and run a scholarship program annually. Determining these scholarships' awarding will naturally experience many difficulties because of the large number of students who potentially receive scholarships and the absence of criteria so that assessment is still subjective. Therefore, Muhammadiyah 4 Jakarta Vocational School requires a decision support system that can compare scholarship applicants' value to facilitate the decision-making process to get accurate scholarship recipients. This decision support system uses the Analytical Hierarchy Process (AHP) method to compare each criterion's value that will produce criteria weighting and the Profile Matching method to determine the final value of scholarship recipients at SMK Muhammadiyah 4 Jakarta. This decision support system is a report of decision results containing the awardees who have been ranked based on the highest to lowest scores. The decision support system for determining scholarship recipients was made using MySQL as a database and PHP Framework as a system creation tool.

Many complex systems in this world have been modeled and analyzed as complex networks. In this research paper, we have modeled specific dataset of MUEJ journal as two-mode network to find its structural properties. Our finding suggests that, this network is evolving with few prominent nodes which are playing the role of connector in this network. This trend can be the reason of highly clustered and more robust behavior in terms of specific nodes in the network.

Chemical Oxygen Demand (COD) is referring to the total amount of oxygen used for a chemical oxidation of organic compounds in a water sample. COD stands as an important tool for water safety and water quality standard. Fast-scan cyclic voltammetry (FSCV) has been reported as a simple and a rapid method for electrochemical measurements, particularly for neurotransmitter compounds in brain and in biological systems. The explicit characteristics of FSCV comes from the ability to measure small volumes of the analyte by adapting carbon-fiber microelectrode as a working electrode at a scan rate of milliseconds. In this research project, FSCV has shown promising results as an alternative method that correlates with the traditional measurementsof COD. Traditionally, COD was more often estimated using oxidizing agents and toxic chemical reagents that have a serious impact on our environment. Unlike traditional oxidation methods, FSCV has been utilized as a powerful an electrochemical tool that allows for measuring COD of Iceberg lettuce washing water samples in a few minutes, without using any oxidizing or toxic reagents. In addition, FSCV measurements showed a high recovery percentage for all washing water samples of the two batches, low organic materials, and high organic materials. Thus, FSCV provides a fast and reliable platform to measure all chemically oxidizable organic compounds in lettuce washing water samples that is directly related to COD, butas an environmentally friendly model based on the oxidation potential.

This Tuned Mass Damper (TMD) is used to improve the structural safety and occupants comfort under wind and earthquake excitation. Pendulum Tuned mass Damper (PTMD), which consists of a moving mass (mt) attached to the main structure using pendulum producing stiffness (k) and viscous dampers (c), is a well-known device used frequently to minimize vibration in the structure. This paper proposes a new model of passive control device, multiple connected pendulum tuned mass damper (MCPTMD), to mitigate the response of structures under various dynamic loads. The MCPTMD consists of multiple pendulum tuned mass dampers connected together in series, which distribute the total mass to separated masses. A numerical model for linear analysis of single degree of freedom system with MCPTMD is derived and verified. The response of the proposed system to sinusoidal loads, which can simulate wind effect, is investigated through the effect of several parameters such as the pendulum length, the excitation frequency ratio, damping, and mass ratio. The response of the structure to earthquakes is also investigated. The result demonstrated that, MCPTMDs has reduced the response of structure to dynamic loads similar to single PTMD with additional merits. The reduction of the total pendulum length, which overcomes the required huge length in case of flexible structures, the existence of more than optimum pendulum length, dividing the mass into smaller pieces, and the interaction to more modes of vibration, are the most important among such merits.

Strengthening and retrofitting existing structures to ensure a long service life has always been a matter of concern that has to be studied every period of time to innovate and produce new beneficial materials that could yield the optimum capacity for the strengthened structural element. FRP has emerged and succeeded in fulfilling that role whether by attaching the FRP outside the structure as externally bonded FRP or by placing them inside the structure itself as near surface mounted. The paper deals with the application of Fiber Reinforced Polymer (FRP) laminates as flexural and shear strengthening materials for bridges, the overall objective of this project is to strengthen two bridges using CFRP (Carbon Fiber Reinforced Polymers); the first bridge is strengthened using Externally Bonded Technique EBR and the second bridge using Near Surface Mounted NSM. The design of the strengthening elements is done based on the Euro code; the paper offers a manual for using the code to strengthen structural elements whether by grooving rods or externally applying them at the needed area. After designing the two bridges, the results showed that they only needed to be flexure strengthened but they did not need to be shear strengthened as the bridges are capable to hold the coming shear loads without being strengthened. The two bridges are strengthened according to the Euro code and the results showed that the strengthening factor of the first bridge is 1,4 and for the second bridge is approximately 2.

Durian is a fruit that Indonesian people demand, but environmental problems arise when the durian season comes due to unutilized durian skin wastes. This research harnesses the waste of durian skin which is then processed into a formulation of gel as an antifungal. The aim of this study is to prove that this gel formulation can inhibit the growth activity of Candida albicans and Trichophyton mentagrophytes. The maceration method was used for extraction processes with 70% of ethanol solvents. Extraction results were then made of gel formulations and separated into several concentrations, formulations 1 (15%), formulation 2 (20%), formulation 3 (25%), as well as base gel as a negative control and gel containing ketoconazole 2% as a positive control. Results show that the gel of durian skin extracts provided a weak inhibition zone at the highest concentration of 25% with an average 5.70 mm ± 0.27 for Candida albicans and did not give any inhibition zone on all gel formulations for Trichophyton mentagrophytes. Preparations of gel formulations were evaluated physically including organoleptic observation resulting F1 in brown, F2 in dark brown and F3 in blackish brown. Homogeneity tests show that all formulations were homogeneous, marked by no appearance of coarse grains. The pH value of all formulations in accordance with the cosmetic standard was about 4.5–6.5. The standard viscosity value of all formulations was between 2000–4000 cps. The stability test of gel preparations shows no changes in the form of low temperature storage (4º C), room temperature and high temperature (40 º C). Thereby, it can be inferred that the durian skin extract can be made in a gel preparation. This Gel has a weak antibacterial activity against Candida albicans and has no antibacterial activity against Trichophyton mentagrophytes.

Cognitive schemas determine the nature of a person’s attitude to himself, to people around him and to the whole world. The emotional sphere of a person and his typical behavioural patterns are formed under the influence of core beliefs. Most cognitive schemas are formed in childhood and adolescence. Therefore, a fundamental study of this phenomenon is required. The aim of the study was a theoretical analysis and empirical research of maladaptive beliefs and cognitive schemas of adolescents with visual impairments. The methods of empirical research were the Dusseldorf Illustrated Schema Questionnaire for Children (Loose, Meyer &Pietrowsky), the Individual Typological Questionnaire (L. Sobchik), the Anxiety Scale (A. Beck) and the Depression Scale (A. Beck). The study sample included two groups of respondents: adolescents with visual impairments and their peers who do not have such impairments. This allowed us to compare the results and establish how the functional defect of the analyser determines the appearance of certain cognitive schemas. The obtained results indicate that knowing which cognitive schemas are typical for a teenager, allows us to predict with a high degree of probability that he has a tendency to increased sensitivity, emotional instability, anxiety or depressive manifestations. In addition, there are described recommendations for psychologists on working with the adolescent`s core beliefs.

The collapse of civil engineering constructions has resulted in injuries, loss of lives, and investments which have been largely attributed to the quality of concrete ingredients used. The need to achieve certain properties suitable for a particular construction and the need to reduce cost in construction projects and achieve optimal results cannot be overemphasized. The study is based on the effect of packing density on the compressive strength of high-strength concrete with the application of metakaolin and conplast SP430 superplasticizer. To achieve this, five different combinations of coarse and fine aggregates for different packing densities were considered, with four different percentages of replacement of cement with Metakaolin (0%, 5%, 10%, and 15%). Therefore, based on the results obtained, it can be clearly stated that the packing density of concrete ingredients should be considered to improve the compressive strength and slump value of high-strength concrete.

When a structural element deteriorates, it becomes liable to the current load and the additional loads that it must be subjected to in the future. Since the columns are the most important structural element, the strengthening of columns, relative to other members is of prime importance. Reinforced concrete jackets are one of the most common techniques used to strengthening columns. In this method, the axial strength, bending strength, and column stiffness are increased. Transferring the load from the original column to the concrete jacket depends on the friction between the column and the jacket. The larger surface area between the column and the jacket, the greater the friction value, thus increasing the axial capacity of the strengthened column. In the case of non-symmetric concrete jacket, such as the Edge and corner columns (three sides jacket and two sides jacket), the surface area between the column and jacket decreases, and thus the friction decreases, and the jacket efficiency decreases. The aim of this research is to study the effect of increasing the number of floors strengthened with non-symmetric concrete jacket on the efficiency of the column after strengthened. The calculations based on the Indian Standard Code IS 15988 (2013) to determine the behavior of concrete jacket. Several columns were modeled using ANSYS software. The analysis results indicate that the use of two-story concrete jacket increases the axial capacity of the column more than the use of one floor concrete jacket. Also, from the comparison of the results, it found that the mathematical design using the equations in the Indian code does not consider the number of strengthen story or the friction between the concrete jacket and the original column.
