Disorders of sexual function seriously disrupt the experience of women followed by periodic but unfortunately they are encor taboo hemodialysis. The aim of our study is to determine the prevalence and find a correlation between clinical and biological parameters on the one hand and sexual disorders observed other. This is a multicenter, descriptive and analytical referred conducted in 63 premenopausal women followed by periodic hemodialysis cross-sectional study. The definition of sexual disorders is primarily based on the subjective assessment of patients. They were selected each time the patient reported that alteration of one or more stages of the sexual response. The mean age of patients was 39.25 ± 15.26 years. Causal nephropathy was 14% of glomerular , vascular 9.5% , 4.7% diabetic , tubulo- intrestitielle 4.7% and indeterminate in 66 % of cases. Sexual problems were present in 69.2 % of cases, in 77% of cases they appeared after the start of hemodialysis . It showed a decreased libido (61.9%) , anorgasmia (38.4%) , vaginismus ( 15%), dyspareunia (30%) , disorders of arousal (53.8 %) , lack of sexual satisfaction (69.2% ), an irregular cycle ( 30%) and secondary amenorrhea (15 %). Only 30 % of patients had previously talked about their troubles : a nephrologist ( 40%), partner ( 20%), friends (20% ) , herbalist (20 %). Twenty percent of these patients were using traditional treatment. A comparative study between the group who had sexual dysfunction (group I) and those who had not ( group II) was performed. No significant difference was found (p> 0.05) Discussion and The sexual problems are common in women hemodialysis. More efforts are needed to better understand their pathogenesis and optimize their care

This study examines staff development as veritable tool for Secondary school effectiveness in Rivers State. The study used a descriptive design. In all, 2 research questions and 2 null hypotheses were posed. The population of the study is 1200 teachers; this consists of 700 teachers drawn from public schools and 500 teachers that were drawn from the private schools. The sample of the study is 480 teachers making 40% of the total population. The collected data were first converted to means and further subjected to Z-test. The means were used to derive answers for the research questions, while the Z-test was used to test the hypotheses of the study at 0.05 level of significance. Findings are that: A significant difference exists between the public and private secondary school teachers of Rivers State in their mean opinion of the type of development programme that are available in Rivers State; there is no significant difference between the opinions of public and private school teachers on the problems of staff development programmes in Rivers State. The recommendations include that government should as a matter of necessity fund development programmes, and teachers should not be reluctant to participate in development programmes.

In this study, an extension of the class of state-dependent model (SDM) for which optimal forecasts may be computed using a recursive examination procedure referred to as the Kalman filter is developed for the analysis of Inflationary rates in Nigeria. The SDM formulation yields a practical means of estimation for the complex time varying dynamical process and provided a generic flexible framework for inflationary rate modelling and inference. A straight forward implementation was achieved in the study by the use of R software package.

The deterioration of the flexible pavements are also due to extreme climatic conditions prevailing in the country in addition to the heavy traffic. The polymer modification of the bitumen can improve the quality of binders and enhance the properties of binders used for the construction of pavements. Ageing of bitumen is one of the principal factors causing the failure of bituminous pavement components due to the prolonged exposure to air and environmental conditions. Ageing are of two types i.e. short term and long term. Short-term ageing occurs when binder is mixed with aggregates in a mixing plant. Long-term ageing occurs after pavement construction and is generally due to environmental exposure and loading. The properties of bitumen mainly depend on the age of bitumen. Therefore there is a need to study the properties of modified bitumen before and after ageing. In this paper the the physical properties of EVA (Ethyl Vinyl Acetate) modified bitumen is discussed, optimum dose is determined and the effect of ageing on the binder prepared using the optimum dose is evaluated.

Corrective Feedback was been extensively debated in the ESL/EFL writing. Both focused and unfocused corrective feedbacks seem to have a positive effect in ESL/EFL writing. The present study examined focused and unfocused corrective feedback for the target form of articles for elementary group as anaphoric reference in written narrative of Iranian EFL learners. 60 participants were selected via the Oxford Placement Test and were assigned to two elementary and advance groups. Then members of each group were randomly divided to subgroups. One subgroup received focused feedback and another half received unfocused feedback. In other words, the focused group received feedback in the form of the correction of articles while the unfocused group received correction of articles error alongside correction of other errors. The participants were given a narrative writing with some pictures and key terms and after reading them, the narrative writing, but not the pictures, was taken away and they were asked to rewrite the narrative in their own words. This task was conducted three times, as a pretest, a post-test and a delayed post-test. This study attempted to examine whether different kinds of corrective feedback does have any effect on learning of articles for elementary level.An in-group paired sampled t-test was calculated between the scores obtained in the pre-test, the post-test, and the delayed post-test.A close examination of the results the data showed that focused corrective feedback was more efficient and significant. The findings are consistent with other studies conducted under similar circumstances.

The application of artificial neural network (ANN) methodology for modeling flood prediction for a large size catchment of the river Jhelum in Jammu and Kashmir (India) is presented. Development of flood prediction models for river Jhelum, flowing through the Srinagar city (J and K ) based on the tail side discharge of upstream tributaries is studied because major inundation caused due to the floods in river Jhelum occurs in the highly populated and largely developing city of Srinagar. The 22 years data records between the years 1990-2012 were used and ANN technique along with conventional regression analysis was employed. The performance was compared based on statically parameters root mean squared error (RMSE), mean square error (MSE), coefficient of determination (R2) and absolute average deviation (AAD) values. NNtp model emerged as the best model with the highest value of R2 compared to other models as 0.93, value of MSE and RMSE being the least as 0.008 and 0.09 respectively. The study proved ANNs to be much better in predicting the flood discharge when judged on all the above parameters. It also showed that transfer function tan-sig performs better than pure-lin in the networks developed for flood prediction. The flood discharge could be thus predicted at least a day before the discharge reaches the station with a high predictability based on the ANN model NNtp.

Water demand in Abeokuta, Nigeria and bacteriological content of public water supplied by the Ogun State Water Corporation, major water supplier in Abeokuta; is assessed in this paper. The water demand of the population was estimated for ten years based on the 2006 National Population Census result, using the geometric projection method. Forty sampling locations were also randomly selected in the city of Abeokuta. Water samples were collected - during the rainy and dry season. The samples were analyzed for total and faecal coliform count using the Most Probable Number method. The presence of Escherichia coli was detected in 39 of a total of 80 samples collected in both seasons. Water demand ranges from 2.01 x 10-7 m3 - 2.48 x 10-7 m3 per year. However, the current volume of water supplied, about 82 million litres per day (2.99 x 10-7 m3 per year), that is when the public utility is in operation is only sufficient to meet the current water demand of the population. The paper argued the need for urgent expansion of the water scheme to adequately meet the present and future water needs of the population and by extension the targets of the Millennium Development Goals by 2015. The paper concludes on the need for periodic monitoring of the state of water from the distribution pipe network from source to the point of use, as well as the water quality parameters that are necessary to ensure the safety of water.

Strangulation is a form of violent asphyxial death and majority of cases are homicidal in nature. This report illustrates an unusual cause of accidental strangulation death of 44 years old female caused due to chunni (a piece of cloth worn around the neck by most Indian women) being caught in moving sugarcane crusher. She was immediately taken to the emergency department of PGIMS Rohtak, where a few hours later she was declared dead, despite all the resuscitation and IVF/drugs. In summary, this case exemplifies the unsuspected inherent danger of wearing long scarf (chunni) while working with machinery.

Cancer is a hyper proliferative disorder marked by metastasis into the vital organs of the body through invasion and angiogenesis. Biodegradable nanoparticles have been used frequently as anti-cancer drug delivery vehicles due to its splendid bioavailability, better encapsulation, and control release with less toxic properties. Various nanoparticulate systems, general synthesis and encapsulation process, control release and improvement of therapeutic value of nano-encapsulated cancer drugs are covered in this review. We have highlighted the impact of biodegradable polymer such as PLGA, PLA, chitosan, gelatin, polycaprolactone and poly-alkyl-cyanoacrylates in the formulation of nanoparticles for encapsulation of cancer drugs. Hence in the current review a detailed studied has been done for the delivering of cancer drugs effectively using biodegradable polymers.

This study assessed the health care services in relation to guardians level of satisfaction with childcare services at the Tamale Central (TCH) and Tamale West hospital (TWH), Ghana. The target populations of this study were guardians of sick children under five who visited the TCH and TWH. A total sample size of 100 respondents was used. 50 participants were each taken from the two Hospitals by using convenience sampling technique. Questionnaires was used for data collection and the data was analyzed using SPSS. A total of 41.2% of the patients were satisfied with the overall service received at the hospital. Guardians who were satisfied with the service significantly had a shorter waiting time than those who were not satisfied. In conclusion, mothers/guardians’ level of satisfaction with childcare are associated with four important dimensions namely; time spent at the hospital, relationship between health worker and parents, affordability of healthcare services and level of confidentiality that exist in the hospital. Long waiting time negatively affected satisfaction. If this is improved upon, it will lead to increased guardian satisfaction regarding the care rendered to their children.
