An extensive review conducted before this study, showed data limitation is the main constrain for multiple regression approach. Thus, new technique has been innovated through bit wear distribution over drilled interval depends on formation fingerprint. Field geological, drilling and logging data collected from three wells located in Blue Nile basin subjected to considerable concentrated analysis. Drilling rate predicted as a function of optimum weight on bit and rotation per minute using Bourgoyne and Young model. The Unknown Bourgoyne and Young coefficients have been determined. Correlations of multiple regressions using Statistica-12.5 software predict acceptable values of nine unknown coefficients. Hypothesis test of predicted coefficients showed over 95% confidence interval which simulated saving in time of drilling by 25%. Out comes was verified through Payzone drilling simulator via simulating actual field observations and re-simulate predicted ROP values. Results revealed the proficiency of predicted drilling rate values. The rate of penetration general equation constructed for each formation; then graphs produced for each formation individually depends on bit type and operational conditions.The methodology and out comes presented in this paper enable prediction of optimum penetration rates directly through accurately produced graphs that is during the well planning period for next wells to be drilled in Blue Nile Basin or other similar formations. This research offers new technique via distribution of drill bits dullness over drilled interval to overcome data limitation constrain. Together with qualitative and quantitative analysis of the optimized results that revealed high potentiality of new technique through both operation and economic benefits on drilling.

The conventional double pipe heat exchanger has less heat transfer rate, so to overcome this problem, this paper focuses on establishing the Triple Tube Heat Exchanger (TTHE) is modified constructive version of double concentric tube heat exchanger by adding an intermediate tube for hot fluid. In this paper the experimental data obtained during the test in a double and triple concentric tube heat exchangers are very much impressive. However, U valve also fitted and were analyzed and the experiment results conforms the effectiveness of the triple tube heat exchanger.

The association diabetes and pregnancy is a common gestational situation that constitutes a real public health in Morocco. The gestational diabetes is defined by the World Health Organization (WHO) as glycemic tolerance disorder that begins or is diagnosed for the for the first time during pregnancy and may cause maternal and/or fetal complications. Our work’s goal is to analyse the epidemiological profile of the diabetic women studied, to follow the course of pregnancy and childbirth and to assess the maternal and fetal morbidity. We present a descriptive retrospective study conducted at the obstetrical gynecology department of high-risk pregnancy within the hospital of maternity SOUISSI in RABAT, MOROCCO, involving 19 pregnant and diabetics women over 326 women consulted. The study lasted 12 months, from January 2019 to December 2019. Data was collected by using medical records. In our series, the prevalence of gestational diabetes is 5,8 %. 8 women have pre-existing diabetes (42,2%) and only 3 have scheduled their pregnancy (15,7%). 11 women have gestational diabetes (57,9%). All our patients were followed and had a controlled glycemic index. This study revealed a large number of maternal complications dominated by urinary tract infections, which represents 31 %, followed by hypoglycemia with a 10,5%, preeclampsia and cetoacidosis in 5% each. For fetal complications, we had 53% cases of macrosomia, 23% of respiratory distress, 18.6% of prematurity, 2,32% of congenital complications. Our results are consistent with most of the series in the literature. These pregnancies remain with more risks than under normal glucose tolerance. Nevertheless, the prognosis of these pregnancies can be improved by early and multidisciplinary management to achieve a glycemic balance avoiding maternal-fetal complications.

The relationship between crude oil prices and stock market indices has always been discordant. The article examines the performance of stock market with the help of different financial ratios used in oil and natural gas sector. Seventeen distinct companies involved in S&P BSE index are taken for our study. Initially 39 financial ratios are taken for analysis and a normality test was conducted on all these explanatory variables to find whether these variables are normal or not? A logistic regression was constructed with help of the selected nine financial ratios as independent variables for determining the performance of S&P BSE index as dependent variable. The classification result showed that, about 75.3 % accurate result for prediction ‘GOOD’ as well as ‘NOT GOOD’ performance of stock. Hosmer-Lemeshow test is applied to find out the overall model evaluation. The study also showed that logistic regression can be used by investors, fund’s managers, investment companies and researchers for academic interest as well as policy implications.

Pulmonary sequestration is a rare congenital malformation that receives its blood supply from a systemic artery. We report a case of pulmonary sequestration initially diagnosed as a hydatid cyst of the lung, surgical findings revealed an abscessed collection related to a pulmonary sequestration of the left lower lobe. Pulmonary sequestration remains a diagnostic and therapeutic challenge.

The study was an examination of the Amnesty Programme proclaimed for militant in the Niger-Delta by the President Umaru Musa Yar’Adua’s administration in 2009, within the context of the role of the Nigerian State in the management and resolution of the conflicts. This was against the backdrop of the protracted conflicts that engulfed the region. At the peak of the conflicts, there were frequent attacks and vandalizations of oil and gas pipelines and installations, of and the rampant abductions of expatriates by militant groups spread over five hundred camps in the creeks of the Niger-Delta. The total population for the area studied was 31, 224,577. Major findings of the study revealed that the Amnesty Programmeproclaimed for militants in the Niger-Delta was to stop the carnage perpetrated by the militants and usher in peace, progress and development in the region. This no doubt entrenched durable peace in the Nigeria-Delta Region of Nigeria.Thus the paper clearly elucidates on the importance of the amnesty programme as a very vital instrument of sustainable peacebuilding, and emphasizes o the need for holistic reforms that address despoliation,pauperization and colossal underdevelopment of Niger Delta region, which were the raison d’etre for the crisis. The paper further made some laudable recommendations towards an all- inclusive amnesty programme which will usher in sustainable peace, security, infrastructure, high human capital and enduring sustainable development to the region.

This paper tries to view monetary policy and national economy. Economic growth is simple defined as a positive quantitative increase in the country output of goods and services (Onwukwe 2003). Produced in a country within a specified period of time. Monetary policy is of importance to every developing nation. Every economy strives to achieve sustainable economic growth and development-explained in terms of positive sustainable increase in Gross Domestic Product (GDP) using the OLS Regression Analysis It was observed that the money supply (m2) contributed positively to the growth of the economy while nominal exchange rate and inflation have a negative impact on GDP which implies that inflation is a constrain to Exchange rate being negative implies that high rate of depression of naira is affecting production capacity especially as most production inputs are being imported and as such the paper recommends amongst others that a Persistent rise in general price level of goods and services must be controlled by the government in order to fight against inflation. This will boost the growth of the economy.

The school environment is one of the most important factor, in promoting learning at every stage of school life. If the environment is conducive, learning accelerates with time and age, that is true for CWSN too. School environment for ‘Children with special need’ consist of infrastructural design of the school, physical resources available at school, the academic resource available at classrooms and school, the behaviour of peers, seniors, school staff and teachers. It has been found that infrastructural facility like pathways, boundary wall, classrooms, toilets, drinking water improves CWSN enrolment as well as attendance. Analysis of data also demonstrates that beautification of school, cleanliness, behaviour of peers/teachers/support staff improves students engagement in school and learning. Teaching-learning aid of every kind support CWSN in engaging themselves in learning.

In today’s competitive business world understanding and developing Employee Competencies remains the key to Organisational success. Understanding employee competencies requires a focused approach to study the key competencies possessed by the employees and hence the study was carried out. The purpose of the study is to investigate the level of employee competencies and to analyse the most and least possessed competencies among employees of manufacturing units across the automobile corridor in Chennai, TamilNadu, India. A structured questionnaire was framed and circulated among the respondents to collect the primary data used for research. The respondents were selected through convenient random sampling method. Data collected from 227 respondents were tabled in SPSS and was anlaysed using statistical tools like factor analysis, reliability analysis and Correlation. The study intends to provide a pragmatic view on the level of competency among the employees and provides insights to the administrators, policy makers and practitioners in the field of human resource management for implementing the findings in developing the competency of employees for the development of the individual and the organisation.

This paper presents the effect of Treated Domestic Waste water (TDW) and lime dosage on cube compressive strength of cement mortar prepared with ordinary port land cement and Portland pozzolana cement. The treated domestic waste water was used as replacement to portable water in the proportion of 0,25,50,75 and 100%. From all the replacements, 50% TDW is noticed as effective based on cube compressive strength. This replacement was kept constant and the lime is added to the effective replacement of portable water in the proportion of 0 to 30 with an increment of 5% by weight of water. From the results is found that, for OPC and PPC mortars the optimum dosages were noticed as 20 and 25% respectively. To compute compressive strength results for lime based mixes a regression model was developed and it was verified with experimental results.
