This paper aimed at investigating the relationship between oil price and some macroeconomic indicators of Saudi Arabia. The co-integration test and VECM were applied to achieve the paper objective. The time series data from (1970-2016) were used. The data was tested for stationarity, and then the co-integration test and VECM were estimated. The results reveal that there is a long run relationship between oil prices and real GDP with weak short run interactions. The result showed that rising of oil prices are negatively correlated with real GDP in the long run. Rising of oil prices may lead to a lower demand for oil in the long run, which will negatively affect government revenue and real GDP growth. The short run results suggest a positive relation between oil prices and real GDP. Rising demand in the short run will increase returns from oil export for the exporting countries. The oil price shocks have significant impact on real GDP in Saudi Arabia. This means the economy of Saudi Arabia will become highly volatile if depends on oil revenue as a major source of income. Diversifying sources of income is highly required in this case.

In this study, changes in some enzymatic activities in different tuber parts of "Florido" and "Bètè-bètè" cultivars belonging to Dioscorea alata species were investigated during post-harvest storage. Indeed, the studied enzymatic activities were those of acid phosphatase and pNP-glycosidases (α-glucosidase, α-fucosidase, α- galactosidase, β-glucosidase and β-galactosidase, α-mannosidase) and polysaccharidases (amylase, cellulase and inulinase). The results showed that the different tuber parts of both cultivars contained acid phosphatase and α-mannosidase activities. Besides, "Bètè-bètè" cultivar also possessed α-galactosidase. As for the polysaccharidases activities, the different parts of both cultivars had amylase and cellulase activities. Otherwise, the detected acid phosphatase, α-mannosidase and α- galactosidase activities in yam tuber part decreased with the storage time while the amylase and cellulase activities increased with the storage time. The enzymatic activities were found to be high in the distal tuber part for both cultivars. This work revealed that both cultivars didn’t contain α-glucosidase, α-fucosidase, α-galactosidase, β-glucosidase, β-galactosidase and inulinase activities. Our results could constitute an attractive biochemistry in the understanding of yams physiology during post-harvest storage.

This work is achieved within the framework of research into didactic of chemistry. It highlights the impact of the teaching of chemistry, as it is currently practiced over the performance of the students at the university in DR Congo. Two Congolese universities were chosen: the "Université Pédagogique Nationale" (UPN) and the "Université de Kinshasa" (UNIKIN). The teaching-learning approach is considered as an experimental method with three independent variables namely modeling, the conceptualization and the theorization. The observations made one the process of teaching-training show that the student is not in the center of the process. The results of the test which followed these observations show that both modeling and the theorization are the most influential factors on the process of teaching-training in the two universities, while the conceptualization is an influential Factor only at UPN. The success frequencies are of 59.7% at UPN and 63.9 % at UNIKIN for students of the both universities, who are able to identify the symbolic level while responding the test. It is however a representing level of concepts, the one of creation of lower taxonomic level concepts of Bloom. Students then succeed more when recognition and understanding questions are given to them. The students’ success frequencies that are able to identify the macroscopic and microscopic while answering questions are of 5.6 % at UPN and 11.3 % at UNIKIN. It can be concluded that the macroscopic, microscopic and symbolic levels of knowledge in Chemistry are not reached by the UPN’s and UNIKIN’s students while learning notions of molecular mechanics. The teaching of molecular mechanics notions as applied nowadays at the higher education level does not facilitate the learning and the deep understanding in Chemistry.

Pregnancy is characterized by a great number of metabolic physiological changes. The present study was designed to assess the levels of fasting blood sugar (FBS), hemoglobin (Hb), proteinuria, systolic blood pressure (SBP) and diastolic blood pressure (DBP) in pregnant women in Nnewi, Anambra State, Nigeria. A total of 100 participants aged between 18 and 36 (22.5±3.5) years were randomly recruited for the study. The participants were grouped as follows: 50 pregnant women and 50 non pregnant women. Thereafter, 5mls each of blood samples were collected from the participants into fluoride oxalate and EDTA containers for the determination of fasting blood sugar and hemoglobin levels respectively using standard method. Urine samples were also collected for urinalysis while the SBP and DBP of the subjects was measured using sphygmomanometer. The result showed that the mean FBS level was significantly lower in pregnant women compared to the control group (p<0.05), while proteinuria, SBP, and DBP were significantly higher in pregnant women than in control (p<0.05) respectively. However, the mean Hb level were similar between both groups (p>0.05). Also, FBS level was significantly lower while proteinuria, SBP and DBP were significantly higher in pregnant women with 6months of pregnancy than those with 5months of pregnancy respectively (p<0.05). Therefore, the implication of this finding is that the pregnant women had neither gestational diabetes mellitus nor anemia rather preeclampsia was predominant among the study population.

Comparative evaluation of wettability of 3 different root canal sealers on dentin. 30 dentin blocks were prepared from single rooted maxillary anterior teeth. After storage and adequate cleaning protocol, they were surface treated with 17% EDTA (Glyde File Prep, Dentsply Maillefer, Ballaigues, Switzerland) Prime Dental Products) for 5 minutes. Following this, they were divided into 3 groups (n=10) for: Group I: AH Plus, Group II: Endo Sequence BC Sealer, Group III: MTA Fillapex. Controlled volume of each sealer was placed onto the dentin blocks using a customized wire loop. The contact angle in each case was measured using Dataphysics OCA Easydrop software on a dynamic contact angle analyzer for 1 minute. Readings will be analysed with suitable statistical tests. The contact angle values for AH Plus sealer were significantly lower when compared to the other two sealer groups. The wettability of AH Plus sealer on the root surface dentin was found to be better than Endosequence BC Sealer and Endoseal MTA.

A cross-sectional study of gastrointestinal helminthes parasites of equine was conducted for 6 months from November 2013 to April 2014 in and around Gondar, to determine the prevalence and associated risk factors of helminthes parasites of equines. A total of 384 faecal samples (donkeys (n=238), horses and (n=146) were collected from randomly selected equine for coproscopical examination and 40 pooled samples for recovery of parasitic larvae were collected and processed in Gonder University Veterinary Parasitological Laboratory. The overall prevalence of gastrointestinal helminthes parasite was 97.4% (374/384) out of which, 28.12% were mixed infections, with the prevalence rate of 97.9% and 96.6% in donkey, and horse, respectively. Coprological examination revealed the existence of five species and four genera of helminthes parasite namely, Strongylus species 47.13 %, Cyathostomes 22.65% Trichostrongylus axei 8.07 %, Triodonthophorus species 6.77%, Parascaris equorum5.2 %, Oxyuris equi 3.12 %, Strongyloides westeri 1.56 %, Anoplocephala species 1.04 % and Gastrodiscus species 1.82 %. No significant variations(P>0.05) in prevalence of helminth parasites were noticed in relation to species, age, body condition score and sex groups of equine, except in case of Parascaris equorum in which prevalence was observed to significantly decrease and increase with age, respectively (P<0.05). The average egg per gram of faeces in this study was 114.7 with a range of 100 to 5,500. The copro-culture study revealed that Strongylus vulgaris, Strongylus edentates and Cyathostomes were the major helminths larvae identified in the area during the study period. Generally parasitism and poly parasitism were the common finding of this work. Equine diseases in general, parasitism in particular, should be given attention in the region where equines are practically participating in all agricultural activities, from tillage to harvest.

The purpose of this study was to examine the contributions of physical facilities on effective management of public secondary schools in Uriri Sub-county, Migori County, Kenya. The research question was; How does thephysical facilitiescontribute to the management of public secondary schoolsin Uriri Sub-County, Migori County, Kenya? The study employed survey design. The study population included all head teachers, all PA chairpersons and all BOM members in the 18 public secondary schools. Purposive sampling was employed in the study. The sample therefore comprised of 18 principals, 18 PA chairpersons and 64 BOM members. Data was collected by use of questionnaires and interview guide. Four of the schools outside the study area was used in piloting the study to act as pre-test to the instruments of data collection to ensure their reliability. Face validity of the instruments was determined by three experts in the department of Educational Leadership and Policy Studies, Rongo University Collegeand the impressions on the instruments improved based on the supervisors‟ advice before using them for data collection. Quantitative data was analyzed by use of descriptive statistics in form of frequency counts, percentages. Statistical Package for Social Science (SPSS) software was used for data analysis. Findings revealed that there was a problem in cooperation among the members caused by lack of team work and financial knowledge which was 51 (85.0%). It was recommended that the BOM members should be involved in regular financial training and budgeting.

This study was designed to investigate the levels of blood glucose and hemoglobin among malaria infected students in Nnamdi Azikiwe University, Nnewi, Anambra State, Southeast Nigeria. A total of 100 participants (75 malaria infected and 25 control subjects) aged between 18 and 30 years were randomly recruited for the study. Thereafter, 5mls of blood sample each was collected from the subjects and dispensed in unit quantity into fluoride oxalate and EDTA bottles respectively for the determination of malaria parasites, hemoglobin (Hb) and fasting blood glucose levels respectively using standard laboratory methods. The results revealed no significant difference in the mean fasting blood glucose level (p>0.05), but there was a significant decrease in the mean hemoglobin level in malaria infected students than in control (p=0.000) respectively. Also, there was no significant difference in the mean values of fasting blood glucose level obtained between students with heavy malaria infection and those with moderate malaria parasitemia (p>0.05), while the mean hemoglobin level observed in the students with heavy malaria parasitemia was significantly lower compared with students with moderate malaria parasitemia (p=0.000). The implication of this finding is that malaria infection depletes the hemoglobin level in infected persons, thus predisposing them to the risk of anaemia

This study sought to establish the influence of participation in games on academic achievement across gender in secondary schools in Rongo Sub-County. The study adopted descriptive survey and correlation designs. The study population included 50 head teachers, 50 games teachers and 2000 Form Four students. The sample size was as follows: 350 form four students participating in games, 175 boys and target population. 175 girls which was 33% of the Face validity of the instruments was determined by three experts in the department from Rongo University. Test-retest method was used to establish the reliability of the instruments which was found to be 0.89 An independent t-test was performed to compare the academic achievement of girls and boys participating in games. The study found out that there was no significant difference in academic achievement among girls and boys participating in games (t 348) =0.752, p=0.453) moreover, the differences in academic achievement is however independent of the sex of the students. Girls who participate in games are likely to achieve just as much as boys who participate in games. The study concluded that Secondary schools need not discriminate on gender while participating in any games programs. The study recommended that all students should be encouraged to participate in games irrespective of their gender. The researcher paid keen attention to research ethical issues and got the informed consent of the respondents and guarded against plagiarism and ensured confidentiality.

An important milestone in the history of blood transfusion was the discovery of the ABO blood groups by Karl Landsteiner, followed by discovery of Rh (D) antigen. Landsteiner’s achievements lead to several discoveries in the field of immunohaematology. The ABO blood group is useful in selecting the appropriately matched blood group during blood transfusion, organ transplantation, finding out association of blood groups and diseases etc. ABO blood group system classifies blood groups of people into four different types namely A, B, O and AB. The need for the study of frequency distribution of blood group is multipurpose. This study was done to know the frequency distribution of blood groups among first year medical students. This study was conducted on 100 medical students in the Department of Physiology at CAIMS medical college in Karimnagar Telangana state. The blood samples were collected by finger prick method. ABO blood grouping and Rhesus factors (Rh) typing determined by glass slide method. Out of total 100 medical students who volunteered, 30 were males and 70 females. In our study, the most frequently occurring blood group was O ( 42%) followed by B group (29%), A group 17% ) and AB group(12% ) . 81% students were Rh positive whereas only 19% were Rh negative. This study may enable us to contact individuals belonging to a particular blood group at times of medical emergencies when blood transfusion is required.

The current wave of unrest among secondary schools students in Kenya is an indication of a serious problem in schools related to juvenile delinquency behaviours. For over two decades, this has been undermining the adolescents’ achievement and development. In this regard, juvenile delinquent behaviours have far reaching consequences; hence the present study sought to explore into the relationship between students’ indulgence in various delinquency behaviours and their academic achievement in Mumias sub-county, Kakemega County, Kenya. Specific objective for the study was to determine the elements of delinquent behaviours among secondary students. The study adopts Jessor's Problem Behaviour Theory (PBT) and ex post facto research design to explain the various study variables. The target population of this study was 54 secondary school deputy principals, 54 guidance and counselling teachers, 218 class teachers, 7548 form two and three students. The sample of the study consisted of 47 secondary school deputy principals, 47 guidance and counselling teachers, 139 class teachers and 365 form two and three students. Data was collected using questionnaire, observation schedules, interview schedules and document analysis.

This paper argues that in 2007, the Chinese A-share market held a significant change in its entire progressing process. The interest rate shock in late May 2001 may be a noteworthy event causing the trend change. The paper aims to test for the trend change in real estate stock prices. Two leading listed real estate stocks were employed. Monthly series spanned the period from 1998M012014M12. Unit root, break-date and cointegration tests were conducted. Both the Perron test (in a mixed IO Model C) and the Zivot-Andrews test (Model C) were performed. A long-run memory of real estate share markets was suggested. Breakpoints occurred in March 2007. Long-run equilibrium did not exist between the stock prices. Real estate shares responded fast and independently to the interest rate shock in 2007. The interest rate shock may result in a trend change in real estate stock prices

This study aims to improve student motivation and learning outcomes by utilizing the Traditional Gorontalo Bilu-bilulu game in learning Social Sciences (IPS). This research was conducted in the fifth grade of Gorontalo State University Laboratory Elementary School and was motivated by the condition of students who showed less student learning motivation and many learning outcomes were below the Minimum Completion Criteria (KKM) because teachers often used the lecture method which tended to be monotonous and not used the game traditionsoanal Gorontalo Bilu-bilulu. This study uses Classroom Action Research methods with stages of planning, implementation, observation, analysis and reflection. The assessment used in this study is a test technique to determine student learning outcomes, assessment of student learning motivation through questionnaires and observation sheets to determine the activities of teachers and students during the learning process. The results of the study indicate an increase in the assessment of student motivation and learning outcomes. In the assessment of student learning outcomes cycle I completeness 45% with an average value of 74.50 while in cycle II completeness reached 80% with an average value of 83. This shows that the use of traditional Gorontalo Bilu-bilulu games can increase motivation and learning outcomes students in social studies learning.

Implementation of PCPNDT Act strictly in past few years has created terror in mind of doctors who are operating imaging technology and infertility clinics. The terror is mainly due to criminal liability under the Act and adverse media publicity. Many doctors had to face criminal charges for trivial things like non-putting of Apron or nameplate, size of display board, clerical errors in filling of form etc. The punishment is serious in the form of imprisonment and penalty further leading to cancellation of medical practitioner licence. Indian Radiological and Imaging Association (IRIA) has taken up the issue seriously and taking the issue to various courts to avoid unnecessary harassment of doctors. Various judgements have come and depicts the stern view of the Courts. The most effective precautionary measures are to maintain records scrupulously, fill the Form-F as provided in the Act, accurately and correctly, submit and maintain the records to the appropriate authority within the stipulated time. Although there is no gap between the intent of the legislature and stand of doctors. Both are in favour of stopping female foeticide and avoiding sex discrimination. Doctors need that PCPNDT Act should serve the intent of stopping sex determination but not as a harassment tool with authorities which is taking away doctor’s self-respect and giving nightmares
