This study investigated the effect of human resource management practice on employee’s productivity in selected deposit money banks in Nigeria. The data for this study was sourced through the use of structured question distributed to the selected deposit money banks in Yola Metropolis. A total of 193 questionnaires were distributed but 166 were successfully retrieved and analyzed. The study employed descriptive statistics, multiple regression technique in estimating the effects of human resource management practice on employee productivity in the selected organization, correlation coefficient was also used to test the extent to which human resource management relate to employee productivity. The study revealed that human resource planning (HRP), recruitment and selection (RS), staff training and development (TRD) and performance appraisal (PA) were positively affecting employee productivity in the selected deposit money banks in Nigeria and were rightly signed, implying that they were consistent with the theoretical expectation of this study. The F-statistics 5.242014, which measured the joint significance of the parameter estimates, was found statistically significant at 5 per cent level as indicated by the corresponding probability value of 0.025272. This implies that all the variables of the model were jointly and statistically significant in affecting employee productivity in the selected deposit money banks in Nigeria. Finally, this result revealed that human resource management practice was positively and significantly affecting employee productivity in the selected deposit money banks in Nigeria.

The leaves of most plants contain two highly differentiated cell types in the epidermis guard cells, which constitute stomata, and trichomes. These cells, the spacing of which is the primary focus are usually separated from each other by pavement cells. Our understanding of the response of angiosperm stomata to environmental parameters remains imprecise because we know little about the mechanisms of stomata control modules. This research was carried out in the old Botanical Garden of the Agriculture University, Faisalabad from January 2019 to June 2019 to examine morphological studies of selected dicots plants leaves with biological active compounds for treatment of cancer using the compound light microscope also to predict algometric relationships between morphologically stomata traits in relation to gaseous exchange in leaf and required allocation of epidermal area to stomata. Epidermal cells varied from round, square to hexagonal with distinctive anticlinal cell wall and sunken stomata distributed on adaxial and abaxial were observed. Stomata are present in the upper and lower surface of the leaves helpful as adaptation for plants during photosynthesis process and stress condition to maintain the water usage.

Increased development in the industrial and transportation sectors today significantly increases the use of lubricants. This means that a significant amount of lubrication is needed to meet consumption needs in the industrial and transportation sectors. Palm Fatty Acid Destillate (PFAD) has a high enough potential to be used as a raw material for making oleochemical products, one of which is solid lubricant. This is caused by the composition of fatty acids contained in PFAD not much different from the composition of fatty acids found in palm oil. This study aims to determine the formulation of solid lubricants (grease) from PFAD and mixture metal soap (Al-Ca) as thickener which has characteristics close to SNI solid lubricants and know the quality of solid lubricants produced. The method used in the manufacture of solid grease (grease) consists of two stages. The first stage is the process of making mixed metal soap (Al-Ca) by mixing PFAD and Al(OH)3 - Ca(OH)2 and analyzing the mixed metal soap. The second stage is the manufacture of solid lubricants (grease) from mixed metal soap (Al-Ca) and PFAD as well as analyzing the resulting product. Based on the research that has been done, the optimum solid lubricant obtained according to SNI standards is in the composition of A1: B1, A1 is the ratio of Al (OH)3 : Ca(OH)2 = 90% : 10% and B1 is the ratio of metal soap: PFAD = 10 % : 90%, so the density is 0.95 gr / ml and the penetration value is 194 (250C), the melting point is 970C and NLGI 4.

The progress of the trade sector is related to the economic field so rapidly. It is accompanied by the development of science and technology, therefore the development of the economy will be more focused on the industrial sector. For this reason, Indonesia, which is one of the countries involved in world trade, needs to address industrial progress, especially related to the Industrial Design that is owned to provide legal protection against the Innovations (Novelty) produced. The method in this research is a normative/doctrinal study. The approach taken is through a legislative approach using materials as research sources that will be sought to be processed and subsequently will be analyzed to find answers of problem discussed. Based on the Research Results it could be stated that the registration Criteria of Industrial Design was to be registered with the new element criteria and as the first registers of the Industrial include a novelty element which must not be the same as the Industrial Design that has been disclosed previous. The right of industrial design legal protection would be coming up where there was an industrial design registration by the designer or owner of the design right, legal protection granted to the industrial design right is granted for a period of 10 years from the date of receipt (application) and cannot be extended again.

Introduction: Medically Assisted procreation (MAP) does not guarantee the outcome of an attempt to conceive. Our goal was to study the factors that can predict the occurrence of pregnancy in stimulated women in our center. Methodology: This was a cross-sectional and retrospective study carried out from August 1, 2016 to January 31, 2018 at the YGESHRTH, comparing two groups of women under the age of 40 years, who had undergone ovarian stimulation during MAP. The first group (group I) consisted of women who had conceived following stimulation during MAP, and group II consisted of those who never conceived. Sampling was consecutive and exhaustive. Discontinuous variables were compared using the Khi-2 test and continuous variables using Student's t-test. A P-value of <0.05 was considered statistically significant. Results: Of the 263 women recruited for the study, 69 (26.2%) had a positive pregnancy test confirmed both by blood samples and ultrasound. The average age of the patients was 33 ± 4.4 years. A significant association was found between the age group of 25-30 years (p = 0.043), a height range of 1.70 - 1.80m (p = 0.001), the transfer of 03 embryos (p = 0.027), the ease of transfer of the embryos (p = 0.030) and the occurrence of pregnancy.

Every student has different learning style and if the method of information delivered conforms to their learning habits, they learn better. To get best out of a student, facilitator needs to understand the student’s learning modalities and ‘tailor instruction’ in such a way that students appreciate and follow it to learning. In this regard a study was designed to analyze the learning style distribution among 1st year MBBS students. A cross sectional questionnaire based study was conducted among 1st year MBBS students (n=152) using validated VARK questionnaire (version 7.8).The questionnaire consists of 16 questions with 4 options, each of which corresponds to a particular sensory modality preference (visual, aural, read/write and kinesthetic). The responses in the questionnaires were assessed according to the keys provided in VARK guide. Demographic details were collected. Preferred learning styles were expressed as frequency and percentage. The response rate was 86.18% (131 students out of 152). Of these 71 (54.2%) were female and 60 (48.8%) were males. All the students preferred more than one sensory modality with 98% quad modal (n=129, M/F=59/70) and near 1% each in tri modal (n=1, M/F=1/0) and bimodal (n=1, M/F=0/1) learning preference. Knowing student’s preferred learning modes; one can focus on developing strategies that are tailored for individuals. All the students in the present study showed multimodal learning styles which points towards the fact that they prefer information to arrive in a variety of modes. Lectures being the major proportion of teaching learning process in 1st MBBS curriculum, one need to adopt active learning strategies and process during lectures which will cater to the needs of all types of learners.

A left ventricular aneurysm (LVA) is a localized dyskinetic area of infarcted myocardium that bulges in systole and diastole. It is a well studied structural complication seen post myocardial infarction although decreasing in incidence due to major improvements in reperfusion therapy. Persistent ST elevation is the most widely reported electrocardiographic manifestation of left ventricular aneurysms. LVA may be evident on chest x-ray, as observed in this case. Diagnosis is non invasively confirmed using echocardiography. Complications of LVA include congestive heart failure, ventricular arrhythmias and rupture that can lead to sudden cardiac death. Surgical treatment is usually effective and followed by a marked improvement in function but is burdened with a heavy post operative mortality. We report the case of a 55-year-old man, with a history of myocardial infarction presenting with a large left ventricular aneurysm.

Background and objectives: Carcinoma prostate is becoming an increasingly significant international health problem. Perineural tumour growth is associated with adverse prognostic features and a poor outcome; hence is a necessary component in histopathological reporting of malignancy. For accurate detection of perineural cancer spread, immunohistochemistry (IHC) with S100 was performed along with haematoxylin and eosin (H&E) stain. This study attempts to correlate the clinic-pathological prognostic factors with PNI, in a regional scenario. Methods: A retrospective study was conducted at a tertiary care hospital over a period of one year. Specimens were trurcut biopsy, TURP chips and prostatectomy specimen, sent in 10% formalin. Paraffin embedded blocks was stained with H&E and representative sections with S100. Relationship of tumor with nerve was established and graded accordingly as: Category 0: nerves without immediate tumor-cell-contact. All nerves being fully surrounded by tumor (classical perineural invasion) were categorized group 3. Two further categories discriminated between nerves that were touched either by carcinoma cells below 50% of the circumference (category 1) or above 50% as category 2. Results: Out of 30 cases of prostatic adenocarcinoma, majority of specimens were needle biopsies (47%). The age of presentation were 55-84years with mean age being 68.93 years. Pretreatment and posttreatment PSA levels were assessed. Most common presentation was bladder outlet obstruction (57%) and treatment given was radical Prostatectomy (44%). Perineural invasion (PNI) was seen in 66.7% of cases and correlated positively with Gleason’s score, pT categories, %PSA. Perineural spread noted in 73.3% cases and negatively correlated with Grade group.

Aim: The aim of this study is to compare the Solubility of Endosequence root repair material fast set putty and Mineral Trioxide Aggregate Angelus (MTA-Angelus). Methods and Material: Solubility was determined by preparing stainless steel ring molds which were filled with cements corresponding to two groups (n = 5). Samples were transferred to bottles containing 10 ml of distilled water and stored at 37°C for 1, 7, and 21 days. Solubility was measured as the difference between the initial weight and the weight at the end of each storage period. Results were analyzed using Mann Whitney U test and Wilcoxon signed rank sum test. Results: The results showed weight loss with time for both materials. The solubility of ERRM and MTA on 21 days was more compared to its solubility after 1 and 7 days. Conclusions: There was no significant difference in solubility between endosequence root repair material and mineral trioxide aggregate.

How to respond to pleural thickening on a chest X-ray or CT? Benign pathology or potentially serious subclinical cancer? The differential diagnosis is wide. Only the pathological examination can decide.

Objective: The purpose of this study was to determine the current trends in usage, handling and dispensation of endodontic files by the dental practitioners of Karachi. Methodology: In this cross sectional study, two hundred and seventy survey performas were distributed to the dental teaching institutes and private dental clinics of Karachi. Survey participants were questioned about the preferred type of endodontic therapy, file system, method of dispensation of files, method of disinfection or sterilization of used files, criteria to discard used endodontic files and the preferred method of removal of debris from used files. SPSS version 21 was used for the calculation of frequency and percentage for statistical analysis. Results: Total two hundred and seventy survey forms were distributed out of which 200 were received with total response rate of 70.07%. 45.5% of dental practitioners perform manual root canal where as 19.5% prefer rotary endodontics. 82.25% respondents preferred to use Protaper files for rotary endodontics. 69.5% of the participants dipped the files in hydrogen peroxide while 20% kept their files in sodium hypochlorite while performing endodontic therapy. Autoclaving of the used files was found to be most common method amongst 87.5% of the participants and 80% of the respondents discard the files on first sign of deformation. 53% of the respondents dipped files in hydrogen peroxide to remove debris after usage.
