The Dynamics of Communication Networking on Small and Medium Enterprises Growth in Entrepreneurial Economies: (Evidence from Nigeria)

This study is designed to investigate the survival strategies for small and medium enterprises in Africa with particular reference to Nigeria. A total of 90 SME’s were randomly selected from business industrial cluster in Lagos (South West) Nigeria and used for the study. Secondary data were used for data collection. Analysis was conducted via descriptive statistics; frequency tables were used for summarizing the data. The Statistical Package for Social Sciences (SPSS) version 2.0 was used, being relatively recent and advance version of SPSS, a multivariate regression model was used to measure the variables of communication networking models on SME’s growth. The result reveals that the variables of communication networking models (knowledge spillover, technological innovation, and interactions within clusters) have significant positive influence on SME’s growth. Both regression and correlation results indicated communication network model variables had positive influence on SME’s growth. Knowledge spillover was the most significant with correlation relationship of 43.3% combined strategies to influence the profitability and growth of SME’s. The study recommended that SME’s owners should explore the dynamic changes occasioned by communication networking models in other to improve on information linkages behaviour, and networking characterization that can improve SME’s existence in the business ecosystem.
Dynamic Model Analysis of Three Phase Induction Motor Using Matlab/Simulink

This paper reproduce the dynamic model of three phase induction motor derived from detailed mathematical equation in MATLAB/Simulink and study the transient performance as well as steady state response of machine including the constant moment of inertia and load torque for the external system. Dynamics generalized approach [1] of digital computer simulation of three phase induction machine is universally applicable method to propose for simulating a dynamic behavior of a large, non linear, time varying physical system. The model can account for unbalanced on both sides of the air gap provided the structure of winding remains unaltered. The simulation in the three-phase Induction motor is with variations in moment of inertia [2]. Transient performance of any electrical machine is greatly affected by sudden changes in its supply system operating speed, shaft load including any variation of moment of inertia due to gear arrangement application. Rotor reference frame is used for the simulation study of this machine. MALTLAB/ Simulink based model is adopted to compare a transient performance of induction machine including main flux saturation with and without the moment of inertia. Simulated results have been compared and verified with experimental results on a test machine setup. During the development of dynamic models of induction motors, most of the researchers neglected the effect of magnetic saturation and assumed inductances to be constant [2]. The computer simulation for these various modes of operation is conveniently obtained from the equations which describe the symmetrical induction machine in an arbitrary reference frame.
Study of salivary gland neoplasms in pediatric age group in a tertiary care centre for head and neck diseases

Introduction: Salivary gland tumors are very rare in children and adolescents. We reported here 11 cases of paediatric salivary gland tumors in a study conducted from July 2015 to June 2017 at Government ENT Hospital, Koti, Hyderabad, Telangana, a tertiary care center. Objective: The aim of this study was to analyze clinical and histopathological features of salivary gland tumours in paediatric age group (children and adolescents). Materials and methods: A total of 11 cases of salivary gland tumors encountered in paediatric age group (0-18 years) were studied and analyzed for age, gender, site predilection and for histopathological types. Results: Parotid and submandibular glands were the main site of tumor occurrence (8/11 in parotid gland, 2/11 in submandibular gland and 1/11 arising in minor salivary glands of hard palate). 4 cases were benign tumors (pleomorphic adenoma) and 7 were malignant tumors (constituted by 6 cases of low grade mucoepidermoid carcinomas and a single case of adenoid cystic carcinoma). Majority of the cases were above 10 years of age with an average of 12.3 years with female preponderence. Conclusion: Present study showed that salivary gland tumors in paediatric age group are very rare and with majority of cases being Mucoepidermoid carcinoma with female preponderance seen in parotid gland. Other glands involved were submandibular salivary glands and minor salivary glands of hard palate. Pleomorphic adenoma was the most common benign tumor and Mucoepidermoid carcinoma was the most common malignant tumor, all of low grade type. One case of adenoid cystic carcinoma was noted in a 15 year old female. N. Sreemani Kumari, Seema Afroze, Madhavi Parigi.

Treatment Outcomes of Patients with Primary Mediastinal Diffuse Large B-CellLymphoma: A Single-Center Experience

Background: Primary mediastinal B-cell lymphoma (PMBCL) is a distinct clinicopathologic entity from diffuse large B-cell lymphoma. The optimal first-line therapy for PMBCL is subject of ongoing debate with no accepted standard of care. Patients and Methods: We searched retrospectively for adult patients with newly diagnosed PMBCL treated at our department between 2002 and 2014. Clinical, management and follow-up data were collected. Staging and response assessment of patients included PET and/or CT scan. Results: Twenty-nine patients with PMBCL (17 female and 12 male) were included. The median age at diagnosis was 36 years (18-79 years). Eighteen (62.1%) and 20 (69%) patients had limited-stage and bulky disease, respectively. All patients were treated with rituximab-based combination chemotherapy; 21 patients underwent consolidation radiotherapy. Seven patients (24.1%) were transplanted (six in first remission and the remaining in second remission). At the end of frontline therapy, 28 patients had responded (27 complete response and 1 partial response) and one patient showed progressive disease. Febrile neutropenia was the most frequent acute adverse event and three patients developed late toxicity. The median follow-up was 51,5 months. The 5-year overall progression-free survival was 83.8%. Four patients died, half of which died within the first year after diagnosis. Conclusion: Our study shows favorable prognosis of patients with PMBCL treated with rituximab-based chemotherapy and consolidation radiotherapy or autologous stem-cell transplant. While consolidation therapy continues to be commonly used, its role has become increasingly controversial.
Lipid Profile In Ghanaian Women With Gestational Diabetes Mellitus

Lipid profile has been a useful tool for the efficient screening and management of patients with diabetes mellitus. Lipid profile changes associated with gestational diabetes mellitus (GDM) are well documented in other parts of the world but not in Ghana. The role of plasma lipids in the pathogenesis of GDM in Ghanaian women was investigated. Ante-natal patients were selected as a case control study including 100 patients with GDM (cases) and 100 pregnant women without GDM (control). Mean values (GDMs vs controls in mmol/L) of TG (2.29± 0.07 vs 1.75±0.08, p<0.001), TCHOL (7.26±0.16 vs 5.85±1.65, p<0.001), LDL (4.71 ± 0.17 vs 3.83±0.16 p<0.001), and VLDL (1.12±0.03 vs 0.80±0.04 p<0.001), respectively were significantly higher in GDMs than the controls. Mean HDL for the GDMs was significantly lower in GDMs compared to controls (1 .2±0.07 vs 1.46±0.08 p=0.023). Mean cortisol concentration for GDMs (509±12.02ng/ml) was significantly higher than controls (402.70±13.12ng/ml) (p<0.05). Also, mean progesterone was significantly higher in GDMs (46.41±2.75ng/ml) than controls (33.06±1.66ng/ml) (p<0.05). These study showed that generally, lipid parameters [LDL, total cholesterol, VLDL) were significantly higher in GDMs compared with controls. However, HDL was significantly higher in controls compared with GDM.
Growth, yield and nutrient status of wheat plants as affected by potassium and iron foliar application in sandy soil

This study was carried out to determine the effects of potassium and different levels of iron foliar applications on growth, yield and nutrient statusof wheat plant grown in sandy soil. Two field experiments were conducted during two successive winter seasons of 2012/2013 and 2013/2014 in Research and Production Station, National Research Centre, Al-Nubaria District, Al Behaira Governorate, Egypt. The experimental design was split-plot in randomized complete block design with three replicates. This experiment includes six treatments in three replicates which were control (without K and Fe), foliar spraying with K (10000 ppm), Fe (500& 1000 ppm), K (10000 ppm) + Fe (500 ppm) and foliar spray with K (10000 ppm) + Fe(1000 ppm). The evidences provided by this experiment indicated that either potassium or iron applications lonely or combined had significant effects on growth , yield and nutrient concentration of wheat leaves, straw and grains and the highest record obtained by low level of Fe alone or combined with K.
Phenotypic and Gene-technological Methods for the Identification of Clinically Isolated Streptococcus pneumoniae from Egyptian Children

Streptococcus pneumoniae is an important human pathogen that causes both serious invasive infections, such as septicemia, meningitis and pneumonia, as well as mild upper respiratory infections. The purpose of the study was to identify the Streptococcus pneumoniae using the conventional phenotypic methods and the PCR assay; especially, to evaluate their usefulness in the identification of the suspected pneumococcal isolates lacking one or more of their typical phenotypic characteristics. A total of 123 nasopharyngeal specimens obtained from children under five years of age, with acute upper respiratory tract infection were subcultured and identified by conventional and gene-technological methods. Forty-one isolates were identified as Streptococcus pneumoniae. Approximately (7.31%) were found to be atypical optochin-resistant, while, (4.87%) were bile insoluble. A 209-bp fragment indicative the pneumolysin (ply) gene was obtained from all typical and atypical isolates. The bile solubility test is more specific than the optochin test for identification of Streptococcus pneumoniae. Genetic test (PCR) for ply could be used to evaluate any isolates giving questionable results by any of the other phenotypic methods.

PSYCHOLOGICAL CONTRACT VIOLATION AND AFFECTIVE COMMITMENT: THE MEDIATING EFFECT OF CYNICISM AND THE MODERATING EFFECT OF EMPLOYEES’ EXPECTATIONS

This research is building on the previous research by examining both the mediating effect of cynicism and the moderating effect of employees’ expectations on the psychological contract violations–affective commitment relationship among academic staff in private universities in Egypt. A sample of 395 academic members responded to a four-part questionnaire measuring research variables (psychological contract violation, affective commitment, cynicism, and employees’ expectations). Cynicism was found to partially mediate the violation – affective commitment relationship. Further, employees’ expectations were found to moderate the violation – cynicism relationship. These results were discussed in light of extant literature. Research limitations and implications were reported
Microvascular density in WHO-based histological grading of meningioma

IntroductionStudies about the difference of microvascular density in each grade of meningioma showed conflicting results. Moreover, in Indonesia, there was no study that determine this association. ObjectiveTo determine the difference of MVD in WHO-based histologicalgrading of meningioma. MethodsThis analytical study was conducted on 33 intracranial meningiomas subjects undergoing surgery at RSUP H. Adam Malik in January 2015-June 2016. The meningioma paraffin block specimens were immunohistochemically processed using the antibody monoclonal PECAM-1 mouse reagent to assess CD31 in the quantification of MVD. The grade of meningioma was determined by WHO classification. Data were collected and analyzed with SPSS 19. Results-In 33 paraffin blocks, mostly most meningioma were grade 1 (87.9%), followed by grade 2 (9.1%) and grade 3 (3%). Mean of MVD in grade 1 meningioma was 16.30 ± 9.65 while in grade 2 and 3 meningioma was 14.20 ± 5.11. Using Mann Whitney, this study showed that there was no difference of microvascular density between grade 1 and grade 2/3 of intracranial meningioma (p=0.869). Conclusion-There was no difference of microvascular density in each histological grade of meningioma. Further research with larger samples and various markers is needed.
ANTHELMINTIC EFFECT OF Solanum lycocarpum IN MICE INFECTED WITH Aspiculuris

This approach intends to add new data on the helminthes parasites of laboratory mice. It has been investigated the anthelmintic activity of Solanum lycocarpum (Solanaceae) extracts against Aspiculuris tetraptera in mice naturally infected. According to the analysis of the results it was observed and an extremely significant difference between TM and C (from 5.64 ± 3.33 to 1.56 ± 3.16). It was published that medicinal plants which were reported as useful in the treatment of diabetes the S. lycocarpum was the sixth most frequently mentioned. According to the results obtained in the present study, we can speculate that the anthelmintic effect of Solanum lycocarpum was noticed due to the concentration of steroidal alkaloid oligoglycosides and short-chain fatty acids.

Fermentation of Apple Pomace Using Mixed Microbial Culture to Organic Acids

The potential of apple pomace (AP) as carbon source for microbial production of biochemicals, via the carboxylate platform, was investigated. The physical and chemical properties of AP were characterized before fermentation by FTIR spectroscopy, TGA, XRD, and compositional (lipids, carbohydrate, lignin and ash) analyses. AP was fermented using a mixed microbial culture (MMC) from wastewater treatment activated sludge. Organic loading (35, 55 and 75 g L-1), temperature (27, 35 and 40°C), gelatinization of feedstock, and a fermentation time of 13 days were examined. The maximum yield of lactic acid was 0.81 g L-1 after 6 days at 35°C and 75 g L-1 feed concentration. However, no significant effect of gelatinization of AP was found to improve fermentation yields. AP fermentation also generated methanol (9.57 g L-1), citric acid (16.8 g L-1), and oxalic acid (24.8 g L-1) with minor amounts of ethanol (0.54 g L-1) and acetic acid (3.42 g L-1). The results of characterization of physical properties, chemical composition and fermentation characteristics of AP waste as source material indicated that AP can be used as potential fermentation substrate using MMC for the synthesis of biochemical products.
Tolerance of two pomegranates cultivars (Punica granatum L.) to salinity stress under hydroponic culture conditions

A hydroponic culture experiment was carried out during two successive seasons (2013/2014 and 2014/2015) on two pomegranates cvs (Wounderful and Manfalouty) to study the effect of salinity on growth and leaf chemical composition of pomegranate seedlings. The plants were two years old at the start of the experiment. The experiment was conducted under controlled conditions in greenhouse, with temperature fixed at 25 ± 3C°, relative humidity between 75 – 85% and 14 hours light exposure. The Wounderful cultivar exhibited higher tolerance to high salinity as compared to Manfalouty cultivar. higher values of shoot length, chlorophyll contents and growth ratio at high salinity concentrations (1500 and 1750 ppm) were recorded for Wounderful cultivar as compared to Manfalouty cultivar. The chemical analysis of mature leaves of the two pomegranate cultivars indicated that Wounderful CV showed significantly higher ratio of N, K, Mg, Fe and Zn than Manfalouty CV. On the other hand, the Manfalouty CV exhibited higher levels of P and Mn contents as compared to Wounderful CV. No significant differences were observed between the two cultivars in Ca and B contents. In the two tested cultivars, Fe, Zn and Mn contents were decreased significantly as a result of increasing the salinity of nutrient solution from 500 ppm to 1750 ppm. This decrement was more pronounced for iron. On the other hand, leaf contents of phosphors and boron were found to be markedly higher in the plants grown under high salinity level (1500 and 1750 ppm NaCl) than those grown in low salinity level (500 ppm NaCl). Generally, pomegranates Wounderfoul CV was found to be tolerant to high salinity than Manfalouty CV. Therefore, cultivation of Wounderfoul CV in newly reclaimed soils of high salinity is highly recommended to avoid the harmful effect of salinity

Understanding The Role of Memorable Tourism Experiences in Loyalty at Giant Panda Conservation Centre, Zoo Negara Malaysia

Memorable tourism experiences (MTEs) have recently emerged to become an important study for tourism destinations to compete in this rapid growing marketplace. Unlike visitors’ loyalty, it has always been a vital objective of service providers. Positive MTEs have been hypothesized for being able to develop future behavioral intentions in the visitors such as revisiting a destination. There is currently still lack of studies regarding the relationship between these two dimensions especially at Giant Panda Conservation Centre (GPCC) in Zoo Negara Malaysia which was established in year 2014. GPCC is the enclosure of the two giant pandas loaned to Malaysia by China to mark the 40 Anniversary Diplomatic Relationship between the two countries. For GPCC, loyal visitors and also new visitors are crucial as the giant pandas will be here for 10 years. Therefore, this research examines whether MTEs can affect a visitor’s loyalty at GPCC in Zoo Negara. A quantitative method was used with a sample of 217 visitors and multiple regression analysis was carried out. The results showed that MTEs have a significant relationship with visitors loyalty. In a nutshell, it is essential for GPCC’s management to increase positive visitors’ MTEs in order to increase the number of loyal visitors who will revisit GPCC and provide positive Word of Mouth to their family and friends so that they will help to attract more new visitors.
Socio-personal and Economic Analysis of Apiculture Enterprise in Hadauoti Region of Rajasthan

This study was undertaken with the objective to study the socio-personal profile of the successful beekeepers and the economic analysis of stationary and migratory apiculture in the Hadauti region of Rajasthan. The average size of migratory apiary units was found to be 192 hives and in case of stationary apiary units on an average there were 78 hives. The analysis of the socio-personal characteristics of the respondents revealed that the majority of the successful bee-keepers were in young age group, farming as major occupation along with bee keeping, high level of extension contact and maximum bee keepers were from other backward category background. The results depicted that the majority of bee keepers were from farming background and they took beekeeping as subsidairy occupation. However, unemployed youth were engaged with migratory apiculture and they adopt bee keeping as their main occupation. The five year average of honey production from migratory apiary units was 40.97 kg/ hive, where as it was only 28.33 kg/ hive for stationary apiary units. The cost-benefit of both migratory and stationary apiary units was found to be 2.61 and 4.00 in the year 2014-15 respectively. Overall, five year average, cost benefit ratio was workout 2.34 for stationary and 3.36 for migratory bee keeping entreprise during the year 2011-2015. It was evident from the results that the net return of bee keepers increased with the increase in the number of colonies.
