PREDICTORS OF STUDENTS’ ATTITUDE TOWARDS MATHEMATICS IN OBIO- AKPOR LOCAL GOVERNMENT AREA OF RIVERS STATE, NIGERIA

The study investigated predictors of students’ attitude towards mathematics in Obio-Akpor Local Government Area of Rivers State Nigeria. Three research questions and three hypotheses guided the study. The study adopted a correlational design. A sample of 350 senior secondary students was drawn from the population through stratified proportionate random sampling technique. The four instruments used for data collection were Mathematics Self-concept Questionnaire (MSCQ), Mathematics Self-Efficacy Scale (MSES), Teachers Competency Questionnaire (TCQ) and Attitude Towards Mathematics Inventory (ATMI) which were validated by experts in measurement and evaluation. The reliability coefficients of MSCQ, MSES, TCQ and ATMI were 0.75, 0.87, 0.80 and 0.85 respectively which were determined through Cronbach alpha technique for internal consistency of the instruments. Linear regression analysis was used to answer the research question while the t-test associated with the regression analysis was used to test the hypotheses at 0.05 alpha level. The results revealed that mathematics self-concept, mathematics self-efficacy and teachers’ competency significantly predicted students’ attitude towards mathematics. These results and their implications were discussed. Among other things, it was recommended that teachers and counsellors should enlighten the students more on mathematics self-concept and self-efficacy which will guide them in having positive attitude towards mathematics. Also mathematics teachers should continue to practice the use of different approaches and techniques in the teaching of mathematics concepts and principles.
BACTERIAL CONTAMINATION ASSOCIATED WITH THE MOBILE PHONES OF HEALTHCARE WORKERS

Background: Despite improvements in modern diagnosis and therapies, hospital acquired infections remain a leading problem of global health systems. Healthcare workers mobile phones are a reservoir for potential pathogens. Even if the high possibility of being contaminated, mobile phones are rarely clean and are often touched during or after examination of patients and handling of specimens without proper hand washing. Aim: The main objective of the present study was to isolate, identify different types of bacteria and their antibiotic susceptibility pattern from mobile phones of healthcare workers. Materials and Methods: Total 100 swab samples were collected aseptically by rolling over the exposed surfaces of the mobile phones inoculated on the agar plates and incubated aerobically. After incubation, plates were examined for bacterial growth. Bacteria were identified and antibiotic sensitivity was tested as per standard microbiological procedures. Observation and Result: All of the tested mobile phones (100%) were contaminated with either single or mixed bacterial agents. The most prevalent bacterial contaminants were Pseudomonas spp. and Escherichia coli followed by Coagulasenegative staphylococci. On the basis of antibiotic susceptibility test, it has been observed that most of the isolated bacteria became resistant to antibiotics, when compared to other isolates. Conclusion: We found that mobile phones are potential vectors which spread antibiotic resistance among microorganisms. So, full guidelines about restricting the use of mobile phones in clinical environments, hand hygiene, and frequent decontamination of mobile phones are recommended to limit the risk of cross-contamination and healthcare-associated infections.
Design of 8T SRAM using FINFET Technology

: Retrieving the data is the major aspect of concern in CMOS technology. At present lower power consumption is the primary objective. The lower power consumption the SRAM cells will be used in the near future extensively. The existing models do not give stability in reading operation because of which a correct logic decision at the output cannot be made. In this paper SRAM cell is designed using FinFET technology and is compared with existing CMOS 45nm technology, and a new SRAM cell structure is proposed which enhances the read stability and write stability with reduction in noise. The transient analysis is done for both CMOS 45nm and FinFET technology based SRAM cell. This proposed model is designed with 8 transistors where 6 transistors are used for data writing and another two are for data reading. The present design increases the read stability.
Magneto-hydrodynamics (MHD) Bioconvection Nanofluid Slip Flow over a Stretching Sheet with Thermophoresis, Viscous Dissipation and Brownian Motion

The bioconvection Magneto-Hydrodynamics (MHD) flow of nanofluid over a stretching sheet with velocity slip and viscous dissipation is studied. The governing nonlinear partial differential equations of the flow are transformed into a system of coupled nonlinear ordinary differential equations using similarity transformation. These coupled ordinary differential equations are solved using fourth order Runge Kutta-Fehlberg integration method along with shooting technique. Solutions showing the effects of pertinent parameters on the velocity temperature, nanoparticles concentration, skin friction, Nusselt number and microorganism density are illustrated graphically and discussed. It is observed that there is enhancement of the motile microorganism density as thermal slip and Eckert number increase but microorganism density slip parameter have the opposite effect on the microorganism density. It is also found that an increase in Lewis number results in reduction of the volume fraction of nanoparticles and concentration boundary-layer thickness. Brownian motion, Nb and Eckert number, Ec decrease both local Nusselt number and local motile microorganism density but increases local Sherwood number. In addition, as the values of radiation parameter R increase, the thermal boundary layer thickness increases. Finally, thermophoresis parameter, Nt decreases both local Sherwood number, local Nuseselt number and local motile microorganism density. Comparisons of the present result with the previously published results show good agreement.
A review on medicinal plants having Antioxidant potential

Natural antioxidants present in the plants scavenge harmful free radicals from our body. Antioxidants exert their mode of action by suppressing the formation of reactive oxygen species either by inhibition of enzymes or by chelating trace elements. Free radicals are the chemical species that have an unpaired electron and play very important role in human health and beneficial in combating against several diseases like cardiovascular disorders, lung damage, inflammation etc. These can damage cell membranes and other vital cell components, such as genetic material in the cell nucleus, and can inactivate enzymes. Damage to body cells and molecules by oxygen containing free radicals has been implicated in a wide variety of diseases. DPPH is widely used to evaluate the free radical scavenging effect of natural antioxidant. Antioxidants in different parts of plants such as ascorbic acid, vitamin E and phenolic compounds possess the ability to reduce the oxidative damage associated with many diseases including cancer, cardiovascular diseases, cataracts, atherosclerosis, diabetes, arthritis, immune deficiency diseases and ageing.
Effects of Classroom Seating Arrangements on Memory Recall

The study examined the impact of classroom seating arrangements on memory recall and its subsequent implied effect on academic performance. The study sought to find out if there was a significant difference in performance of students who sat towards the front, middle and back positions in the classrooms. The experiment was conducted on sixty (60) Form-Two students of Kwegyir Aggrey Memorial School. Three conditions with 20 subjects were randomly assigned to each condition. The Brown-Petersons Auditory consonant Trigram was used and subjects under each condition were presented with nonsense trigrams to learn and recall either immediately or after performing a mathematical test. A difference in performance in the recall of words of students who sit in front of the class, middle and of students who sit at the back of the classroom was obtained and was realized from the results that seating arrangements have no effects on the performance of students. As against previous findings, no significant difference occurred between performance of students who sat in front, middle or at the back. This indicated that students perform the same irrespective of their seating position in class.
Risk Adjusted Performance Evaluation of Balanced Mutual Fund Schemes in Pakistan

Mutual fund existed since 1964 in Pakistan capital market carrying certain benefits like risk diversification, assured returns and professional management for the retail investors. Growth of this investment mode has not been in the parallel levels in Pakistan as is the case around the world but still mutual funds in Pakistan appeared to be highly competitive financial service industry. This research paper aimed to study the performance of some selected mutual fund schemes in Pakistan based on risk-return relationship and various measures. Five balanced schemes offered by various mutual funds in Pakistan are selected for this study from 2010 to 2013. The analysis has been made on the basis of mean return, beta risk, total risk, Sharpe ratio, Treynor ratio, Jensen Alpha and Fama’s decomposition measure. The empirical results reveal that average returns of selected portfolio are below from market returns, mix trend of risk in selected schemes and overall defensive beta values. In short results indicate underperformance of most of schemes during selected span of study. Keywords: Risk adjusted performance, Balanced mutual fund, Treynor, Sharpe and Jensen’s Alpha measure.

PASSIVITY AND ISS FOR SINGULARLY PERTURBED SYSTEMS WITH EXOGENOUS DISTURBANCE

This paper proposes a composite approach between passivity and ISS for singularly perturbed systems (SPSs) with an exogenous input coupled with slow and fast dynamics. The insight links between passivity and ISS are presented explicitly. We first find a linear matrix inequality (LMI) condition under which the SPSs are strictly passive on an exogenous input for all sufficiently small singular perturbation parameters, and then establish a relationship between passivity and input-to-state stability (ISS) for this SPSs with an exogenous input and the problem of designing a robust control law is addressed for such SPSs with a reference input such that the closed loop SPSs are robust passive and ISS on an exogenous input when the singular perturbation parameter is sufficiently small. To achieve this, a matrix inequality-based criterion is proposed and proved. The criterion is then converted into a LMI feasibility issue for the purpose of implementation, in which the control gain matrix is derived by solving such a LMI.
Molecular Diversity in Castor Germplasm Collection Originated from North-Eastern Hill Province of India

A total of fifty one accessions of castor (Ricinus communis L.) germplasm collected from North-eastern hill region of India were employed for current investigation involving 35 castor EST-SSR marker for polymorphism at genetic level. Seventy six alleles with an average frequency of 2.14 band per primer was generated among which 29 were polymorphic with a polymorphic percentage of 82.8. The number of allele ranged between 3 and 2 based on which PIC value was generated between 0.04 0.73 with an average PIC value of 0.38. The genetic similarity index used for dendrogram, resulted into 3 major and 6 minor clusters with a Dice similarity coefficient ranging from 0.65 to 0.90. Confusion probabilities and limit of discriminating power ranged from 0.021 to 0.623 with a mean of 0.402 and 0.348 to 0.979 with a mean of 0.598 respectively. Highly diversity genotypes can be used for crop improvement programme like tagging of germplasm, identification or elimination of duplicates in the gene stock, establishment of core collections, sorting of populations for genome mapping and in breeding program to obtain more variability in the castor crops.

Enhanced production of protease from Bacillus subtilis AP-CMST W3 and its application in leather processing and silver recovery

In the present study, Bacillus subtilis AP-CMST W3 was isolated from an estuarine environment for the production of protease for various biotechnological applications. The process parameters were optimized to enhance the production of protease by the candidate organism. Protease production was found to be optimum in the presence of 0.5% maltose, 0.5% casein, 0.1% magnesium chloride, 3% sodium chloride, at pH 7.0 and 40 °C. The enzyme was purified by the combination of ammonium sulphate precipitation, dialysis and sephadex G-75 gel filtration chromatography. The molecular weight of the purified enzyme was estimated as 21 kDa. The purified enzyme demonstrated appreciable activity at higher temperature (40 °C) and pH 7.0. The enzyme showed potent activity on various surfactants and detergents. It dehaired goat skin and hydrolyzed the gelatine layer of used “X” ray film. These properties reinforce the possibility of inclusion of protease from B. subtilis AP-CMST W3 in leather processing industry.
Competitiveness and symbiotic effectiveness of Rhizobial inoculants on Field Pea (Pisum Sativum) under field condition

Field pea (Pisum sativum) is widely cultivated in Ethiopia as a source of protein and integrated in crop rotation to improve soil fertility because it fixes nitrogen with rhizobia. However, effectiveness in nitrogen fixation depends upon the selection of symbiotically effective rhizobia to enhance production. Thus, a study was conducted to evaluate the performance of three inoculants (isolates); FBR 11, FBR 15, FBR 23 on growth, nitrogen fixation and yield under field conditions in relation to a commercial rhizobial strain 1018 at Kulumsa Agricultural Research Center during 2015-2016 growing seasons. Inoculation of field pea showed a highly significant (p ≤ 001, p ≤ 0.01 and p ≤ 0.05) effect on all parameters compared to the un-inoculated plants in the field trial. Accordingly, plants inoculated with isolate FBR15 and Strain 1018 showed a significant increase in nodule number 84-112 NN/plant (10 times), NDW 77-94 mg/plant (12 times) against the un-inoculated control plants, and they also showed a 20-25% increase in both parameters in comparison to FBR11 and FBR23 inoculated plants. The treatments with FBR15 and the reference strain 1018 also showed significant difference in grain total nitrogen, N uptake and straw N uptake, and seed protein with 50-100% and 12-20% difference from the un-inoculated control plants and other Rhizobium treatments, respectively. Positive correlations were observed with respect to the number of nodule and shoot dry weight (r=0.49, p<0.05), number of nodule and number of pod (r=0.59, p<0.01), number of nodules and total grain yield (r=0.56, p<0.05), and shoot dry weight and N content (r=0.73, p<0.001). Although the MPN count of rhizobia in the soil at the experimental site was 1.5 × 104 and contained sufficient number of indigenous rhizobia, they were not effective that was indicated by the nodulation and yield parameters of the un-inoculated treatments. The data in general, showed that the rhizobial inoculants, particularly FBR 15 isolate was nutritionally versatile, ecologically competent, and symbiotically effective rhizobia compared to the commercial inoculant (strain 1018) that could be used as commercial inoculants for pea production after it is tested (validated) at different agro-ecological conditions.

India 474005 Author for Correspondence Sushil Sharma Email-sharmasushil07@gmail.com ABSTRACT During present investigation, extracts of various parts of two common weeds i.e. Calotropis procera (Aiton) W.T. Aiton and Ipomoea carnea Jacq. were evaluated for their fungicidal and fungistatic potential. Results showed that among ethanol, chloroform and hexane extracts of leaf and stem of C. procera and I. carnea, the ethanolic extract of C. procera was consistently found most effective than other extracts against the mycelial growth of A. alternata at a concentration of 10mg/ml. The extracts were found highly effective when compared to systemic and contact fungicide used as positive control. At 10mg/ml concentration, highest zone of inhibition was recorded with ethanolic leaf extracts of C. procera. Furthermore, at the same concentration chloroform leaf extract of I. carnea exhibited comparatively less inhibition against the test fungi. The extracts that exhibited good results during in vitro studies were further tested in vivo against fruit rot of tomato.
The Effect of Training of Stress Management on life Quality and Mental Control of Mothers with Autism off Spring

Autism disorder is one of the inclusive growth disorders determined by the stable deterioration of social interactions, relationship delay or distortion and limited-stereotype relational pattern. Due to the high rate of problems among autism children, families and mainly mothers suffer from high psychological stresses. Psychological health of parents can affect from disability of child and usually the pressure on mother is higher than fathers. Some fathers consider the psychological pressures on mothers more dangerous than the child’s disability itself and introduce it as a threat for whole family. Present research is conducted to investigate the stress management education influence on quality of life and control of thoughts among mothers whose children suffer from autism. The study conducted in Bandar Abbas and the semi-experimental test method is used as pre-test post-test between control and intervention groups. The statistical society consisted of 30 mothers whose children suffer from autism and in0available sampling method is used to select the participants. Participants were randomly assigned to two control and experimental groups. Subjects were tested in two pre-test and post-test by to psychological tools named as quality of life scale and Wels and Davis thought control scale. The intervention of stress management is conducted in 10 sessions for 2 hours on experimental group. The control group did not receive any intervention and data were analyzed by SPSS22 in 0.01 significance level. The results of multi variant covariance test indicated that the stress management influence on quality of life is significant (SF=160.36, P=0.01) but the stress management on thoughts control is not significant (SF=19.45, P=0.01). In aspect of physical health (SF=1.45, P=0.01), psychological health SF=7.21, P=0.01), life environment SF=7.18, p=0.01), the stress management was significant. The stress management influence on social relations was not significant (SF=0.77, P=0.38).
EFFECT OF SUBCHRONIC EXPOSURE TO CHROMIUM ON HEMATOLOGICAL AND BIOCHEMICAL PARAMETERS OF MALE ALBINO RAT

Objectives: Exposure to chromium, the transition element found in many compounds of earth’s crust, leads to various health hazards including cancer, dermatitis, damage of liver and kidneys, and reproductive toxicity in both male and female. Toxic effect of chronic exposure to chromium at low environmentally relevant dose is recently recognized and less studied. In the present study, we evaluated the effect of subchronic exposure to low doses of chromium VI (K2Cr2O7) on various hematological and biochemical parameters in male albino rats. Methods: Male albino rats (160±10 g) received 1/25, 1/50, and 1/100 of reported oral LD50 dose of chromium VI (K2Cr2O7) for 90 consecutive days. After treatment, the blood was collected for analysis of various hematological and biochemical parameters. Results: Exposure to chromium VI at 1/25 LD50 dose caused decrease in body weight gain and reduction in the weight of the reproductive organs along with increase in the weight of the liver and kidney. Numbers of red blood cells, white blood cells, platelets, and hemoglobin concentration reduced with increase in clotting time. The total sperm count and motility was also reduced in exposed rats. There was a decrease in plasma protein and albumin concentration, with increase in plasma glucose and cholesterol level. The activity of enzyme alanine aminotransferase and enzyme aspartate aminotransferase was stimulated in treated rats. Conclusion: The results of the present study revealed that chronic low-dose exposure to chromium VI resulted in a toxic effect in experimental male albino rats.
The Implementation of AVO Formulations to the Water Saturated Sandstone and Lithological Reflection in Shallow Gound Water

The aim of this implementation is to predict the expected reflection as the fluid (water) boundary in saturated sandstone. This boundary was be indicated by rising amplitude of the signal reflection boundary versus offset, called Amplitude versus Offset (AVO). The author here presents the opportunity to make implementation of AVO formulations to identify the saturated sandstone. This is as a meaning of identifying the water table in shallow seismic exploration. Theoretically, the water table should produce a clear AVO response, which exactly different from a lithological boundary. There are some stages to show how we can use this phenomenon to identify the water table. Firstly, data collections over the water-table and lithological reflection have been conducted by squenced aquisitions. Secondly, the investigation of amplitude errors by instrumentation and processing had also been done. Finally, the AVO analysis proved that the AVO model able to distinguis different between the water-table and lithological reflection. KEY WORDS; AVO, Shallow reflection, Ground Water, Sandstone
Economic cost of dementia in Australia 2016-2056

The increasing number of people with dementia is placing stress on care and support services provided through both informal care arrangements in the community and formal home care packages and residential aged care facilities. The AIHW (2012) estimated that in 2011, 77.3 percent of males and 65.2 percent of females with dementia lived in the community. The AIHW calculated the number of people with dementia living in the community by subtraction, using information on the overall number estimated to have dementia minus the estimated number of people living in cared accommodation. The number of permanent residents in residential aged care facilities (RACFs) (identified through the ACFI data) was scaled up by 5.7 percent as the 2009 SDAC indicated that this proportion of people with dementia were living in types of cared accommodation other than RACFs.
