This study aims to explore the possibility to use rubber particles derived from discarded tire as aggregates for replacing fine and coarse natural aggregates to produce cement concrete towards resource recovery and environmental protection in Vietnam. The experimental results showed that the workability of fresh rubberized concrete was improved when replacing natural fine aggregate (sand) with fine rubber particles (2.5-5 mm) at the replacing proportions of 30-50% by volume, and when replacing natural coarse aggregate (crushed stone) with coarse rubber particles (5-20 mm) at the replacing proportions of 10-30% by volume. With respect to the mechanical properties of hardened rubberized concrete, a larger reduction in the compressive and flexural strengths was generally found when the replacing proportions increased and when coarse aggregate rather than fine aggregate was replaced by rubber particles at all replacing proportions. However, the study results also indicated that using fine rubber particles for replacing fine natural aggregate at the low replacing proportion (up to 10%) might not cause the significant effect on the compressive and flexural strength of rubberized concrete. Contribution/ Originality
This is the first ever study in Vietnam to investigate the potential for using rubber particles derived from discarded tires to replace natural aggregates in producing cement concrete towards resource recovery and environmental protection in Vietnam.
The paper primarily focuses urban material culture and its adverse impact on urban waste management and finally the environmental services. The study results show the increase of personal purchasing capacity, pleasure in aesthetes, upholding the social esteem push people towards material culture at a hyper level. It causes a serious risk of waste management and ecological aspects. Urban governance across the world has to cost a lion portion of its annual budget for waste management and environmental preservation. However, the more wastes (liquid and solid) generates everyday that cannot be managed more than seventy or eighty percent resulting in a severe environmental costs. The paper mainly aims to find out the socio-psychological causes of increasing material culture and its effects on urban governance, waste management and city environments. The study has been conducted in qualitative approach and secondary sources have been used for data collection. Immaterial culture might be a suitable source of pleasure, happiness and social status that have to take as a social movement to minimizing material culture and moreover, socio-politically we have to follow the ideology recycle, reuse and reduce. Contribution/ Originality
The study is one of very few studies which have investigated the adverse impacts of material culture on socio-cultural and ecological services as it also erodes spiritualism, humanism, social harmony and ecology. The paper contributes the first logical analysis of the negative effects of fast fashion producing countries’ (Bangladesh) labor rights and environments.

One of the most important tasks of educationists from preschool centers in Malaysia is to prepare the young child for global readiness. This study involved (N=529) preschool children in Malaysia. The main objective was to gauge the level of global readiness of children aged (5-6 years old) according to several dimensions of global readiness namely (a) diversity and multiculturalism (b) use of ICT (c) communication and multiple language ability (d) problem solving and (e) environmental awareness. Responses to the Global Readiness Scales were recorded and analyzed using One Way ANOVA. The main findings indicated that (a) a generally high level of global readiness in diversity dimension (b) high level of global readiness was found in usage of ICT and problem solving dimension (c) moderate level of global readiness were found on communication and environmental awareness (d) all types of preschool scored high level of global readiness except in Islamic based preschool which scored moderate (e) significance differences were found according to the types of preschools in all dimensions except cause and effect. The findings suggest that (a) there is need to conduct qualitative study on the implementation of global readiness in the preschool centers (b) there is the need to develop global readiness curriculum modules to be integrated effectively in teacher training (c) a cross-cultural comparative study should be conducted across preschools at the regional and international level to gain wider perspective on the implementation of global readiness. Contribution/ Originality
This study is one of the few studies which studied the effect of early childhood education on the global readiness of preschool children in Malaysia. Hopefully this study will create greater awareness among curriculum developers on global readiness as well as enhance teacher’s knowledge and competencies on global readiness.
For characterization of the performance level of top weightlifter the world records (achieved till 31.12.2016.) were used. The relative performance was determined as the ratio of the records and own bodyweight (category weight). It is demonstrated that both in case of male and female lifters the performance and the relative performance depend on the body-mass, however the tendency is opposite. Theoretically the performance is the function of body-mass on the 2/3 power, so it increases with the body-mass, but the relative performance decreases as a function of body-mass on the minus 1/3 power. Evaluating the results in the clean and jerk (C&J) we have to take into account the own bodyweight of the lifters, as well, because the lifters lift during the execution of the C&J attempt the barbell + the own body, standing up from squatting position. So the weigfhtlifter lifts not only the barbell, but also his/her own bodyweight! The results with this correction show rather good agreement with the theoretically determined performance ratios for the different (8+7) weight categories. Contribution/ Originality
This study uses new estimation methodology for analysis of the relative performance of the top weight lifters, taking into account during the lifted the complex system of body+barbell.
This study was carried out to determine the prevalence of pre-hypertension and assess the renal function in pre-hypertensive students in College of Health Sciences, Okofia, Nnewi. A total of 210 (99 males and 111 females) apparently healthy respondents aged 18-28, were recruited for the initial screening. Their blood pressure readings and body mass index (BMI) were obtained, whereas 5mls of blood sample was collected from 18 prehypertensive and 19 normotensive subjects. 5mls of blood was collect from eligible subjects and dispensed in plain containers for estimation of biochemical parameters. Serum creatinine, urea, Na+, K+, and Cl- were analyzed using standard methods. Result showed a prevalence of 11.4% with a higher percentage in males (12.12%) than in female (10.81%). BMI was significantly higher in pre-hypertensive than in normotensive (26.31±4.76 Vs 21.60±2.44;p> 0.05). Systolic (SBP) and diastolic (DBP)(126.67±5.76 Vs 107.68±9.90; 79.56±6.57 Vs 69.52±7.39;p> 0.05) respectively were significantly higher in prehypertensives than in normotensives. Interestingly, there was no significant difference in the value of renal function markers of the prehypertensives when compared to normotensives (p>0.05). However, there was a positive correlation between SBP and serum urea level(r = 0.628; P =0.009). Therefore, the prevalence of prehypertension in this population was low with reference to studies in other populations. Importantly, this preliminary study did show that the renal functions are not compromised. Contribution/ Originality
This study documents the Prevalence of Prehypertension and Assessment of Renal Function among the Prehypertensive Students of the College of Health Sciences, Nnamdi Azikiwe University, Nnewi, Anambra State, Nigeria, a study which is original to the authors as outlined above.

Despite these opportunities there exist several internal and external challenges for the government of Pakistan to implement this multidimensional project. The study is organized to analyze some internal and external challenges for Pakistan that are associated with the implementation of CPEC project. Contribution/ Originality
Advances in technology are classified as one of the external factors that trigger organisational change, even for Higher Education Institutions. The transition to e-learning presents new challenges as expectations and roles of employees and students evolve. The primary objective of this study was to investigate employee perceptions of the Open Distance and e-Learning model at a university in South Africa. The research questions for this study addressed factors that necessitate change and the barriers to change in Higher Education Institutions. The study further investigated the extent to which competences of employees match the strategic objectives for the ODeL business model and also recommended intervention strategies that can be employed to minimise risk and smoothen the change process when ODeL is introduced. A quantitative research methodology was used to arrive at the findings through a survey. The findings revealed that most of the employees acknowledge the need for change. But the ODeL model was not well embraced as the intervention that could solve the discrepancies. This was because results showed that some employees did not have appropriate capabilities to effect the change, the management was not perceived to give them the necessary support, and employees could not see how the ODeL intervention would benefit them. A recommended area for further research would be on how the institution could optimise its resources for a cost-effective ODeL. Contribution/ Originality
The primary contribution of this paper revealed that although open distance and e-learning initiatives are crucial in tertiary institutions, which have to cater for growing numbers of students, without the necessary commitment from management to allay the concerns of employees, transformative change in the form of technological advancement would be exacerbated.
This study appraised government feeding programme on increased school enrollment, attendance, retention and completion among secondary school students in Maiduguri, Borno state, Nigeria. Descriptive survey method was the research design adopted for this study. The target population for this study comprised day public secondary schools in Maiduguri, Borno state, with a total population of nine thousand three hundred and thirty eight (9,338) students. The sample of 934 students was selected using simple and stratified random sampling techniques. A self- developed questionnaire was the instrument of data collection. The response mode for the instrument was a modified four points Likert type scale. Descriptive statistics of frequency counts, and percentage scores was used to answer the research question, while Chi-square test was also used to analyze the hypothesis at 0.05 level of significance. The results showed that the school feeding programme improved the nutritional health status of the students. The findings recommended that Federal Government should assign Ministry of Finance to perform monitoring and evaluation functions, allocate more funds and logistics and give up-to-date records to the state government to make sure the feeding programme achieve an optimal level of the desired objectives. Appraisal tools other than questionnaires should be employed when appraising the students cognitive capabilities in order to ensure effective outcome and reporting. Borno State government Donor agencies, and stakeholders in education should increase funding and make sure the schools have constant supply of food through committed food distribution channels. Individual targeting should be used as a mechanism to motivate enrollment in school or more regular attendance. The target group should be families with children who are not in school or who are frequently absent. Contribution/ Originality

Individual targeting should be used as a mechanism to motivate enrollment in school or more regular attendance. The target group should be families with children who are not in school or who are frequently absent.
In modern day society, cleaner, more sustainable forms of electrical power are needed to keep costs lower and to ensure a healthier environment for future generations. The use of piezoelectric devices installed within a road would enable the capturing of kinetic energy from automobile traffic. This energy can then be converted into electrical energy and can be used to offset some of the power coming from the main grid. Such a source of power can also be used to operate road lighting and signage systems, or it could be injected to the grid at an appropriate Point of Common Coupling (PCC). This paper discusses investigation of energy harvesting from piezoelectric materials when installed in a road. The work includes conversion of kinetic energy to electrical using piezoelectric materials, the energy harvesting method, and experimental research on piezoelectric materials.

Determining the relationship between percentage resection and development of short bowel syndrome is important as it provides information on the expected outcome of the resection carried out which will enable the surgeon to prepare adequately to manage such patients. Ten adult Nigerian indigenous dogs with mean body weight 11.2 kg were used in this study. The animals were premedicated with atropine (0.04mg/kg) and xylazine (1mg/kg) intramuscularly. Anaesthesia was induced with thiopentone sodium (10mg/kg) intravenously. The abdominal cavity was entered through the ventral midline incision. Three animals each were subjected to 50% and 60% small intestinal resection while four animals were subjected to 70% small intestinal resection. The animals subjected to 50% and 60% intestinal resection did not manifest signs of short bowel syndrome. However, the animals subjected to 70% small intestinal resection manifested clinical signs attributable to short bowel syndrome. The animals subjected to 50% and 60% small intestinal resection had remnant small intestinal tract of up to 100cm while dogs that underwent 70% resection had remnant small intestinal bowel length of less than 100 cm. It is therefore, concluded that 70% small intestinal length resection is the minimum that can produce short bowel syndrome in Nigerian dogs and animals with remnant small bowel length of less than 100 cm after undergoing resection will come down with short bowel syndrome. Contribution/ Originality
This study is one of very few studies which have investigated the crown-rump length, total small intestinal length and the percentage small intestinal resection that will result in short bowel syndrome in Nigerian dogs.
Modern power system is a complex network comprising of numerous distributed generators, transmission lines, switchgears, distribution network and variety of loads. However, the quality of the power supplied to the end users is deteriorating as network expand due to inherent system disturbances such as voltage dips, harmonic distortions and phase angle deviations caused mainly due to low voltage network faults. This has resulted to high level of customers’ dissatisfaction and complains. Research has shown that over 60% of system perturbations are caused by natural events such as lightning strikes and system faults. There are various methods power utilities are employing to realize a robust and reliable power transmission system. Such methods include re-conducting of transmission lines, construction of new transmission lines and in recent time installation of Flexible AC transmission system (FACTs) devices. The FACTS are power electronic devices that have ability of controlling the network voltage condition both in steady and transient state of complex power system. The most common power electronic controllers are, Dynamic voltage stabilizer (DVS), Static Synchronous Compensators (STATCOM), shunt compensators and Unified power flow controller (UPFC). The STATCOM devices are the most widely installed power electronic controllers as they provide excellent performance in stabilizing the power system both in steady state and non-steady state (system disturbances) conditions. It is for this reason the author propose installation of STATCOMs to reinforce the Kenya Power national power grid to achieve a robust and resilience system which improves the power quality supplied to the end users. Contribution/ Originality
This study is one of very few studies which have investigated the impact of installing STATCOM devices to enhance the quality of power supplies and improve on power stability/ reliability in Kenya power grid. In recent time, the power grid has experienced several power disturbances in major load centers.
This paper presents a summary of the results of a study on the use of a local admixture Ipomoea asarifolia (‘Ajara’) on the compressive strength and weight of specimens made from both cement stabilized and unstabilized lateritic soils. The effect of Ipomoea asarifolia extractions on the strength characteristic of lateritic blocks was investigated. Three mix proportions of cement: laterite of 0:1, 1:2 and 1:4 using lateritic soils from four different locations from around Ife while using six concentration levels of extracted liquid of Ipomoea asarifolia (0; 20; 40; 60; 80 and 100%) in fresh water as the mixing “water” (fluid). Ipomoea asarifolia specimen was analyzed to determine constituent chemical composition and their effect in reaction with other materials. Sieve analysis of the lateritic of the lateritic soil mix was carried out while a total of 132 – 100 mm cubes size were tested using a 1570 kN Avery-Denison Compression Testing Machine.

The right to good administration is a concept through which there are protected the rights of citizens against the abuse of public authorities and institutions, based on the general principles of European administrative law, such as: objectivity, proportionality and equality, non-discrimination, respect for human rights and fundamental freedoms. Maladministration occurs when a public authority or institution violates the principles of good administration and it does not respect the fundamental rights of citizens. For the achievement of the paper we have used content analysis and descriptive documentary research of the documents relevant to this very current issue and of particular interest to citizens, European institutions, national public authorities and institutions, especially the European Ombudsman Report for 2015 and 2014. In conclusion, the most common instances of maladministration in the European Union refer to transparency issues (transparency of decision making, transparency of lobbying activities), ethics, human rights etc. Contribution/ Originality
This study is one of the few that has analysed, in parallel, the most frequent types of maladministration found in the European Union and in Romania, starting from the definitions given for good administration.
Tanzania has one of the largest populations of domestic ruminants in Africa. Their performance is less than their potential. Health, particularly disease due to gastrointestinal parasites, is a major constraint to improved productivity. Internal parasites also affect the country’s very diverse and huge array of wild ruminants. This review is based on a thorough search of the formal and informal literature pertaining to gastrointestinal parasites of ruminants in Tanzania. The occurrence and geographical distribution of helminth (nematodes, trematodes and cestodes) and protozoan parasites are presented. Cattle, goat and sheep nematodirus (roundworm) infection usually comprises mixed infections of several taxa of which 13 species in nine genera have been recorded. A total of seven species of trematodes (flukes) in six genera have been found. Some six species of cestodes (flatworms) have been recorded, three being in the genus Taenia. The most prevalent species of protozoan parasites, of which seven have been identified in cattle and 18 in sheep and goats, belong to the genus Eimeria: four other species of protozoan parasites are also recorded. A general overview of the epidemiology of gastrointestinal parasites is provided and the main methods of control are discussed. Contribution/ Originality
Domestic ruminants are an important part of the Tanzania economy. They contribute to food security, biodiversity, household income and human welfare. This paper reviews with the aid of 74 published references the status and distribution of the main internal parasites of domestic ruminants in Tanzania.
The objectives of this study were to determine the growth and survival parameters and blood IgG and total protein levels of calves born in the first production year of Brown Swiss and Simmental cows imported from Austria to a newly-established dairy cattle enterprise in Manisa, Turkey. The study material consisted of 62 Brown Swiss and 266 Simmental calves. Calves were separated from their mothers after birth and put into individual sections and subjected to colostrum feeding. At the end of three days, calf grower feed was given. Calves were weaned around 60-days of age unless there was an abnormality with their development. Birth weights, weaning weights on the 65th day, and daily weight gains of calves were 40.31 kg and 41.76 kg, 77.16 kg and 83.9 kg, 0.56 kg and 0.64 kg for Brown Swiss and Simmental breeds respectively. Simmental calves were born heavier and had more weight gain until weaning. We determined that breed and sex affected calves’ growth while delivery method only affected birth weight. Calves with high birth weights caused difficult birth, but this effect disappeared until weaning. Survival rates of calves until weaning were 98.39% for Brown Swiss and 95.49% for Simmental. The survival and mortality rates of Brown Swiss and Simmental calves at weaning were at normal levels, while the calves with difficult birth had losses around 10%. Contribution/ Originality
This study is one of the very few studies which have investigated the performance and adaptation levels of imported breeds in Turkey. It contributes in the existing literature by producing information on the growth, survival, immunity levels and locality adaptations of calves born in Turkey after heifers’ importation.
Growth characteristics of Bifidobaceria pseudocatenulatum G4 in low concentration milk medium were studied. During cultivation process, profiles of cell growth, pH changes, organic acids and sugar profile were monitored. A finding showed that final cell concentration (cfumL-1) obtained in 2 and 4% (w/v) milk concentration was two times lower than in comparative media. However, 6% (w/v) skim milk gave a promising media for B. pseudocatenulatum G4 growth. Organic acids production (acetic, lactic, formic and citric acid) by strains was detected in all milk medium concentrations and similar profile were observed. Except for formic acid which actively produced in 2 and 4% (w/v) milk concentration. The accumulation of formic acids was believed due to carbon limitation. As for sugar profile, co-metabolized galactose and glucose were observed in 2, 4 and 6% (w/v) skim milk concentration. Meanwhile high carbon remains occurred in 8 and 10% (w/v) milk concentrations after cultivation period. Among all concentrations, milk with 6% (w/v) concentration showed better support for cells growth without formic acid presence and low carbon remains at the end of cultivation period.

This study determined the influence of nursing-mothers’ parity and index child factors on adoption of exclusive breastfeeding practice by rural nursing-mothers in Imo State Nigeria. Nigeria has only 13% compliance to exclusive breastfeeding practice, hence the need for this study that employed descriptive survey design to obtain information from 340 nursing mothers from three selected communities in the state. The target population of the study was all the 405 nursing-mothers with children aged twenty-four months and below in the selected communities but 340 nursing-mothers responded. Instruments for data collection were structured questionnaire and Focus Group Discussion (FGD). Reliability of the instrument was established and r = 0.8. Ten nursing mothers from each of the communities participated in FGD. Results of the study revealed that exclusive breastfeeding practice was 13.5% in the target communities. Only parity, place of ante-natal care and place where the child was delivered were statistically significant (P<0.05). The study concluded that parity and type of facility attended for ante and natal care played a role in the adoption of exclusive breastfeeding practice. There is need to strengthen maternity facilities to render effective exclusive breastfeeding promotion, and also to follow up mothers in the community. Contribution/ Originality
This is an original research article. The study contributes to existing literature on exclusive breastfeeding, particularly as it relates to nursing-mother’s parity, facility where she received ante-natal care, where she delivered her child and index child’s factors. These variables received little attention previously and hence, this study fills this gap.
This study aimed at investigating linguistic errors committed by students majoring in Non-English Department in writing English composition. A total of 20 first year students at Economic College IBBI Medan who have taken an English subject course were involved in this study. Their compositions were analyzed for the purpose of scrutinizing linguistic errors they made. In analyzing the data, this study adopted Hubbard (1996) classification of errors including grammatical, syntactic, substance, and lexical errors. The results of data analysis discovered that students committed 352 errors in their compositions with the following frequencies: 82 errors in propositions, 32 errors in tenses, 29 errors in articles, 48 errors in subject verb agreements, 37 errors in word order, 17 errors in capitalization, 21 errors in punctuation, 28 errors in spelling, and 58 errors in word choice. Hence, it is concluded that the most difficult linguistic error that students face is prepositions, while the easiest part of linguistic error that poses difficulty for students is capitalization. Contribution/ Originality
The paper's primary contribution is finding that Indonesian EFL learners tend to face problems in deciding which prepositions to use in writing. The results showed that almost all types of prepositions were misused by students. Thence, it is important for English teachers in Indonesia to put more emphasis on preposition usage.
