This study was designed to assess oral health knowledge, attitudes and practices among secondary schools students in Sana'a city, Yemen. A cross-sectional questionnaire-based study was conducted on (1000) of secondary school students, (500) male students and (500) female students with an age ranged from 16-19 years. A selfadministered structured questionnaire consisting of 24 questions on socio-demographic data, oral health knowledge, attitudes and practices was distributed and collected data was subjected to statistical analysis. The mean knowledge scores for the secondary school students was 72.27 with a statistically significant difference between males and females (P = 0.001). Nearly 75.5% of them reported that regular visits to the dentist are necessary. In contrast, nearly (60.3%) of them visited the dentist when they felt pain and toothache was the most leading reason provided for visiting the dentist (62.1%). Moreover, nearly 42.9% of them reported that fear of needles and drilling was the major reason for their fearing of visiting the dentist. The use of toothbrush and paste was the most oral hygiene method used (78.6%). About 44.6% of them brushed their teeth once per day and 36.8% of them spent one minute for brushing their teeth. Nearly 44.3% of them reported that the time of tooth brushing was before going to bed only. Finally, most of them (74.1%) reported that their parents advised them about the importance of oral hygiene without their watching and did not supervise them. It showed that the students had good oral health knowledge. However, their oral health knowledge, attitudes and practices were bitter in female students than male students.

The aim of the present investigation was to develop controlled release tablet of Abacavir sulphate using. Azadirachta indica (Neem gum) and comparison with official guar gum (BP). Additionally, physiochemical properties of the gum were evaluated. Totally five batches abacavir containing extended release tablets were designed using neem gum / guargum characterized for preliminary trial. Best formulation was selected for optimization by 22 central composite design. In this Input variable were Neem gum/Guargum (X1) and Microcrystalline cellulose (X2). The output variables were Hardness (Y1) friability (Y2) swelling index (Y3) and in vitro release (Y4). The optimized formulations were subjected for inviro-invivo correlation. The study results revealed optimized batch A2 showed hardness of 5.8 kg / cm2, friability 0.63 %, swelling index 84.3% and in vitro release of 90% over the period of 12 h.

Also the in virtro in vivo correlation coefficient obtain from point –point analysis of optimized tablets was 0.98. The optimized tablets exhibit super case 11 mechanism.

Nigerian economy is a multi-sector economy with agricultural and manufacturing sectors as the prime sectors. This study focused on the effect of commercial bank credits on the output of agricultural and manufacturing sectors in Nigeria. It spanned for the period of 31years (1986-2016) and made use of secondary data extracted from the Central Bank of Nigeria Statistical (CBN) Bulletin for various years. The study adopted ex-post facto research design and employed the Autoregressive Distributed Lag (ARDL) bound test and Ordinary least squares multiple regression analysis considering necessary diagnostic tests such as unit root test, test of normality, heteroskedasticity test, and cointegration test. The findings revealed that commercial bank credits have significant positive effect on the productivity of agricultural and manufacturing sectors in Nigeria. The implication of the findings is that more credits to agriculture and manufacturing sectors in Nigeria will increase output in the respective sectors. Hence, the researcher recommended among others more lending to agricultural and manufacturing sectors so as to boost productivity of these sectors.

The paper investigates the impact of the contribution of road infrastructure expenditure on economic growth of Benin Republic using Jarque-Berra, White test, Breusch-Godfrey, Cusum and Cusum of squares techniques for the period (1985-2015). Overall the results reveal that gross domestic product, gross capital formation, labor productivity and road infrastructure expenditure play an important role in economic growth in the Benin Republic. More importantly, the study finds that road infrastructure expenditure in the Benin Republic has a significant positive contribution to economic growth in the long run than the short run. It is the same result with the gross capital formation. The labor production has a significant positive contribution to economic growth in long run. On the basis of these results analysis, it is strongly suggested to formulate certain recommendations in the field of economic policy that improves the road infrastructure expenditure as well as gross capital formation for sustainable economic growth in the Benin Republic. A new model has been proposed to the General Directorate of Public Works in effectively monitoring the level of road infrastructure expenditure in terms of growth and poverty reduction objectives

The Qur‟an contains the Divine revelations of Allah (The exalted) to mankind. It is the message from Allah to man and therefore of utmost importance to us. Therefore, some special knowledge of the circumstances that surround the Glorious Qur‟an is also necessary for fuller understanding of its meaning and implications. This paper, therefore, studies one of the important science of the Qur‟an (that is Miraculousness of the Qur‟an) comparatively from the views of two prominent Islamic scholars, such as; Shaykh „Abd Allah bn Foduye who was born in the year 1179A.H/1766-7.C.E and (d. 1829 C.E), and Bediuzzaman Sa‟id Nursi who was born in 1877 C.E in the small village of Nurs in the province of Bitlis in eastern Anatolia of the old Ottoman Empire (modern day Turkey) and (d. 1960 C.E), who had a good numerous of things in common and differ with Shaykh Abd Allah in some explanations especially in „Ijaz al-Qur‟an (Miraculousness of the Qur‟an).This paper attempts to discuss definition of the „Ijaz al-Qur‟an, the views of Bediuzzaman Said Nursi and Shaykh Abd Allah bn Foduye on „Ijaz al-Qur‟an. The paper also explains where these two prominent Islamic sages are compatible and incompatible concerning their thoughts on the Miraculousness of the Qur‟an. This paper also explicit the two great scholars have expresses this aspect of „Ijaz alQur‟an (Miraculousness of the Qur‟an) in details. The whole idea of selecting these renowned scholars, despite the difference in the time of their existence and place of activities, is for a number of reasons. Firstly, to show the efforts of the two scholars in reviving the religion of Islam in their respective domains and times and vindicating its truth despite the challenges they encountered from those who were against the teachings of Islam. Secondly, is to show the people of these two continents that there are great scholars who worked vigorously about Qur‟an and to benefit from their knowledge and good character. Looking at the nature and scope of this research, analytical method was employed by studying and analyzing the works of the two scholars.

The spatial patterns of urban land use at both the macro and the micro levels are a central issue in global change studies. The land use/land cover (LU/LC) changes are real important to have proper provision and use of natural resources and their management. Land is becoming a scarce resource due to immense agricultural and demographic pressure. Hence, information on land use /land cover and possibilities for their optimal function is essential for the selection, preparation and implementation of land use schemes meet the increasing needs for basic human needs and welfare It was done by using the data SOI Toposheets, Landsat TM, (1991), Landsat ETM+ (2001), LISS-III (2011) and LISS –IV (2016) and with the aid of using Remote Sensing and Geographical information Techniqnies. The supervised classification method is used to classify the land use and land cover of the study area. The major findings of change detection analysis revealed that the maximum change in the land use and land cover from 1981 to 2016 has been seen in the instance of the built-up area, which has varied from 2.89% to 40.36%. The major expansion of the built-up area is mainly along the highways and the outskirts.

This complete-enumeration, before-and-after type of study (without controls), was conducted in April 2018 on 53 First-year MBBS students (24 females: 45.28% and 29 males: 54.72%) at a medical college in Kalwa, Thane, Maharashtra, India. After explaining the purpose of the study to the prospective participants, written informed consent was obtained. Those who did not give written informed consent or those who were absent during either pre- or post-test were excluded. The pre-test, conducted after traditional didactic lectures on respiratory system, comprised 15 questions (2 marks each; total 30 marks). The post-test was conducted after case-based learning, using a questionnaire that was identical to that of the pre-test. The outcome studied was the difference in cognitive domain scores after attending traditional didactic lectures (by a pre-test) and after case-based learning (by a post-test). The difference between the mean pre-test score (14.11 +/- 5.12; 95% CI: 7.13 - 15.49) and post-test score (25.92 +/- 4.63; 95% CI: 24.68 - 27.17) was highly significant (Z=12.455; p<0.0001). In the pre-test, the first quartile score of female students was on par with the third quartile score of their male counterparts while the third quartile score of female students was on par with the maximum score obtained by males. The pre-test result also exhibited higher variability in scores obtained by male students. In the post-test, the overall scores of male students improved and the maximum score and third quartile were identical for students of both genders. In the pre-test, the gender differences in mean scores were statistically significant for 5 out of 15 questions, while the mean scores in the post-test did not exhibit significant gender differences. Extension of this study to other topics in the First-year MBBS course may enable formulation of suitable teaching-learning techniques.

This study examined stress and stress management amongst undergraduates of Nnamdi Azikiwe University (Unizik), Awka, Nigeria. The person – environment fit theory was adopted as the theoretical framework. Cluster and simple sampling techniques were used for this research work, while the sample size used was 200. Data was collected via questionnaire and in-depth interview. Questionnaire data from the field was analyzed using the statistical package for social sciences (SPSS). The study revealed that there is no relationship between sex of a student and their awareness and knowledge of stress management techniques. Also there was no relationship between the academic level of students and their acceptance that stress influences academic performance in various ways. The researcher recommended that the school management should add stress management skills as part of the school curriculum, inform students in advance of the difficulties they might face and encourage them to develop their own strategies to achieve personal goals during the orientation week for new students. It was also recommended that close lecturer - student relationships be cultivated so that students can approach lecturers on personal issues to improve their academic performance. The paper concluded that when students are exposed to knowledge and skills relevant to stress management, they will effectively cope with school related stress, graduate with good grades and in turn, be in a position to contribute positively to national growth.

Awareness of poor visual acuity that can be treated easily and effectively in the student groups can add positively for their quality of life and quality of their study. A descriptive cross-sectional study done among students aged 14–19 years in secondary schools in Sulaimani city from six secondary schools both male and female are enrolled. To determine the prevalence and pattern of refractive errors in this students group and determine the prevalence of different types of refractive errors which include (Myopia, Hypermetropia & Astigmatism). The total of 848 students aged 14–19 years, were examined. Examination included visual acuity testing by E chart, and refraction was done for those having visual acuity less than 6/6. The refractive errors of the students' eyes were measured using streak self -luminous Retinoscopy and non-Cycloplegic auto-refraction. Out of 848 students, 737 (86.9%) were emmetropic (normal visual acuity) and 111 (13.1%) were ametropic. Of those 111 students, Myopia with myopic astigmatism was the commonest types: 41(36.9%), and 52(46.8%) students respectively. Hypermetropia found in 14(12.6%) students. Anisometropia was found in seven (6.3%) students, represents (0.8%) of the sample. Amblyopia was found in 11(10%) students, of overall sample (1.3%) had Amblyopia. Only one had bilateral Amblyopia. Bilateral vision correction to 6/6 was found in 81(73%) students, (9.6%) of the study sample, Six (5.4%) students (0.7%) had unilateral correction to 6/6, Nine (8.1%) students (1.1%) had bilateral correction to 6/9, and 15(13.50%) students, overall represents (1.8%) of them, their vision was correctable to less than 6/12. Those having glasses earlier were 35(31.50%) students represent (4.1%) of the sample while 76(68.50%) student need glasses. Prevalence of refractive errors was 13.1% of the sample. Simple myopia was the most prevalent refractive errors that corrected to 6/6, While. Amblyopia was more common in hypermetropic. Anisometropia was the least common of the sample.

The proliferation of small arms and light weapons is and has remained one of the major security challenges Nigeria, Africa and the World at large is currently facing. The thrust of this paper is on the impact of uncontrolled proliferation, stockpiling, trafficking, availability and usage of these arms on Nigeria‟s national security as it is believed to fuel alarming levels of armed crime, communal conflict, political instability, social unrest as well as making all the geo-political zones of the country to be flooded with small arms. The paper further argues that the inability of the Nigerian government and its law enforcement agencies to check the menace has led to a major challenge of security, as it was revealed that previous and current efforts at tackling the issue has not yielded much efforts as only a few number of seizures of illegal arms has been made hence the proliferation continues to sustain and exacerbates armed conflicts within the country. The study is anchored on the realist and failed state theories using secondary data, literature evidence, descriptive and historical methodology. Findings reveal that the impact of small arms and light weapons on the society is too grave and devastating to be treated with kid‟s glove as it leads to massive loss of lives and properties, erodes social capital, facilitate corruption and climate of impunity. The paper recommends that the government must rise up to the challenges of tackling the menace with all seriousness and commitment.

The gastroretentive drug delivery system is site-specific and allows the drug to remain in the stomach for a prolonged period of time so that it can be released in a controlled manner in the gastrointestinal tract. The purpose of the research work is to formulate and optimize the gastro retensive film (GRF) containing Propranolol hydrochloride in order to prolong the release time and improve the bioavailability. Five basic gastroretensive films were developed by solvent casting method for preliminary trial . The best formulation was subjected for two factor two level design approach. Independent variables selected were concentrations of Eudragit S 100 (X1) and Eudrajit RL 100 (X2) and dependent variables were Folding Endurance (Y1) Tensile strength (Y2) Elongation at break (Y3) and in vitro drug release (Y4). The results of the study indicate optimized formulation (P2) exhibit folding endurance 114, tensile strength 1.3 kg mm2, Elongation at break 22% and in vitro release 46.5 % for 12h. The in vitro release data were well fit into Higuchi and Korsmeyer-Peppas model and followed non-Fickian diffusion mechanism. The gastro retensive formulations can be used in diseases where an extended release of propranolol is required.

Poverty is a very complex problem, which is not only limited to economic issues but also related to issues in other fields. State policy (government) is needed in helping solve the problem related to poverty especially in the field of law that is by providing legal protection through the provision of legal aid to the citizens. It is an attempt to fulfill and at the same time be the implementation of a legal state that recognizes and protects and guarantees citizens' human rights on the need for access to justice and equality before the law and fair trial. Islamic values not only regulate the things that are private but also public policies and also constitutional so that the jurists make Islamic law as one of the primary references in establishing positive law in realizing the certainty of law and justice one of them through the fulfillment of the right to legal aid that is part of the legal system of the Pancasila Legal State. Judging from the perspective of dignified justice, the provision of legal aid to the underprivileged is one manifestation of humanizing humanity, that is the manifestation of respect for one's dignity and dignity. The policy of legal aid should be oriented to the legal philosophy of human beings. That is, the law, including the arrangement of legal aid for justice seekers who can not afford, must serve human beings.

Amrutharistam is a vital Ayurvedic formulation used for all kind of fever and rheumatic fever, which is prepared by fermenting the decoction of Tinospora cordifolia containing berberine as one of the active ingredient. Preliminary analysis indicated the presence of berberine being the largest concentration. The HPLC carried out in Lichrospher 100, RP-8e (250*4.6*5) column, mobile phase consisting of phosphate buffer and acetonitrile (70: 30). The determining wavelength was confirmed as 343nm. Five marketed formulations of Amrutharistam A-I, A-II, A-III, A-IV and A-V showed berberine concentration to be 9.63µg/ml, 10.10µg/ml, 10.20µg/ml, 9.64µg/ml and 10µg/ml respectively. The result showed the peak area response is linear within the concentration range of 10-50µg/ml with a correlation coefficient of 0.9998. Recovery studies 50%, 100% and 150% were conducted by standard addition method and found to be 99.804%. The developed and validated method can be effectively applied to the quantitative determination of berberine in Amrutharistam.

The aim of the study was to establish the attitude of students to learning Biology, to examine the academic performance of students in Biology and to compare the attitude of male and female students towards class size. This study investigated the attitude of students to class size and learning Biology. It established the effect of class size on students’ academic performance in Biology in Senior Secondary Schools in Gombi Educational Zone, Adamawa State. The study adopted survey design Three research questions and three hypotheses were postulated. The target population for the study comprised 17, 523 senior public secondary school students in Gombi Educational Zone, Adamawa State, and a sample size of 400 was selected by stratified sampling technique. The research instrument titled “Attitude of Students’ to Class Size and Learning of Biology Questionnaire (ASCSLBQ)” was adapted from Omwirhiren & Faith, 2016. The instrument comprised of 46 items divided into 3 sections. The face and content validity of the instrument was established by two experts in Counselling Psychology and Test and Measurement in the Department of Science Education, Adamawa State University, Mubi. Test-retest method was used to carry out the reliability test and the reliability coefficient was 0.82. The data collected were analyzed using descriptive and inferential statistics which included percentages, mean, Standard Deviation, and Analysis of Variance (ANOVA). The findings revealed that classes are very rowdy because students are too many, making students not hearing the teacher well during lessons, students love Biology as a subject, because they feel at ease in Biology class, feels good when they solve Biology questions, and are willing to spend more time reading Biology books. There is no significant difference between male and female students attitude towards class size. There is significant difference between the male and female students’ attitude towards the learning of Biology; and there is significant difference between male and female students’ academic performance. Biology is a general subject offered by all senior secondary school students, but the classes allocated to them are too small, as a result the classes are overcrowded. Even though the students have keen interest in Biology, they cannot perform practical very well because the teachers cannot give individual attention to the large numbers of students, others cannot even hear him well during lessons because there are no public address systems. This factor could adversely affect students’ academic performance in Biology. Based on this finding it was recommended that number of students in a class should be streamlined to at most 40 students. In addition, government should provide materials for teaching and learning Biology.
