A fully implicit non-standard finite difference scheme for one dimensional Burgers' equation

In this paper we have studied a numerical approximation to the solution of the nonlinear Burgers' equation. The presented scheme is obtained by using the Non-Standard Finite Difference Method (NSFD). The use of NSFD method and its approximations play an important role for the formation of stable numerical methods. The main advantage of the scheme is that the algorithm is very simple and very easy to implement.
Comparative Analysis of the Physicochemical Characteristics, Phytochemical Components and Fatty Acid Profile of Avocado Pear (Persea Americana L) Pulp and Seed Oil

The physiochemical properties, phytochemical content, and fatty acid profile of Avocado pear (Persea americana) pulp and seeds oils were investigated. The pulp oil was extracted using the hot water flotation method while the seed oil was extracted by the soxhlet extraction method. Extracted oils were analyzed. The pulp oil was emerald green while the seed oil was brownish red in colour. Pulp oil has significantly higher blue (27B) on Lovibond scale. The oil yield, smoke point and flash point of the pulp oil were 28.26%, 171.00 °C and 201.67 °C respectively. Which were higher than 13.64%, 100.00 and 130.66 °C seen in the seed oil. Iodine value, FFA, peroxide value and saponification value of the pulp oil were respectively 50.70 g/100 g, 0.53%, 1.10 mEq/kg and 218.66 mgKOH/g while those of the seed oil were 40.68 g/100 g, 2.85%, 2.16 mEq/kg and 198.31 mgKOH/g respectively. Saponins, alkaloid, phenol, tannin, and oxalate content of the seed oil were significantly higher than those of the pulp oil, with respective values of 12.23, 1.06, 5.06, 3.05 and 10.07 mg/100 g. Flavonoid was however higher in the pulp oil, at 6.20 mg/100 g. avocado pulp oil contained 43.23% oleic acid, 19.78% linoleic acid. It contains only 35.31% total saturated fatty acids. The seed oil was shown to contain 55% palmitic acid, as the predominant saturated fatty acid and contained a total of 69% saturated fatty acids. It is recommended that avocado seed oil be refined before use for culinary purposes.
Development of a Sharp-Cut Cyclone for Ambient Aerosol Monitoring Applications

Aerosol samplers for ambient PM2.5 are required to possess a steep aerodynamic particle size selection curve, i.e., a 'sharp cut' at 2.5 mu m aerodynamic diameter. For long-term and continuous PM monitors the selector system also requires low maintenance and the ability to operate at high loadings. While a sharp cut is easier to achieve with an impactor-based selector, the other require ments are more easily met with a cyclone. Four alternative PM2.5 selectors were tested against these criteria: two were pre-existing commercial designs and two were novel cyclone prototypes. The main aim of the work was to assess the characteristics of the selectors when clean and under various loading conditions. The aerodynamic size-selection characteristics of the PM2.5 selectors were tested before and after loading with dust, under both laboratory and field conditions. Aerosol penetration measurements were made using an Aerodynamic Particle Sizer. Many repeat tests were performed on two specimens of the Well Impactor Ninety-Six (WINS), two specimens of a novel Sharp-Cut Cyclone (SCC), one member of the GK cyclone family (GK4.39), and one University Research Glass ware (URG) cyclone. Four loadings of the WINS and SCC were made in the laboratory using a narrow-fraction alumina dust. The penetration curves were measured after each loading. Five cumulative outdoor loadings were made by setting up four PM2.5 samplers, two with the WINS and two with the SCC, in a suburban garden during the summer months. The penetration curves were mea sured at weekly intervals after sampling times ranging from 96 to 132 h. Three further cumulative loadings were tested in a similar experiment in a city-center underground car park. When clean, all three PM2.5 size selectors were shown to have 50%penetration (D50) values close to 2.5 mu m, although the penetration curve shape differs for the three selector designs. Under loading the D50 value for both the WINS and SCC fell, with the decrease being largest for the WINS. With high loadings the SCC D50 fell to 2.35 mu m and the WINS D50 fell to 2.15 mu m. The WINS deviation was large enough to potentially lead to under sampling of PM2.5. The SCC cyclone was seen to provide a sharp cut for ambient air sampling applications that is less affected than the WINS by loading. Additionally, the SCC is a dry system whereas the WINS uses an oiled substrate. While the WINS cut point is unlikely to shift to an unacceptable degree during 24 or 96 h sampling periods, it would perform less well than the SCC over extended sampling periods.
Cross-Cultural Issues and Human Resources Management in BRIC Countries

The BRICS market is a significant economic block, accounting for over 40% of the world population and over 20% of global GDP. International companies are eager to do business. Cross-cultural issues, however, can be barriers in human resource management (HRM) and slow the process to achieve credibility among local employees, particularly if Western approach is adopted among local employees. This study focuses on exploring cross-cultural problems in emerging markets, such as Brazil, Russia, India, and China, or infamously known as BRIC, using Hofstede 's expertise to recognise local values that influence HRM periscope and recommend HRM approaches that can be taken to meet local employee standards. From the study, multinational companies are recommended to use the RBV strategy to achieve competitive advantage and local integration. By highlighting the descriptive analysis of the systematic literature approach and using web tool research, a critical assessment of findings shows that each BRIC country has its specific culture and challenge embedded in local culture. Therefore, fully understanding local values are very useful in coping with contrasts and spot opportunities.
The Possible Therapeutic Effect of Mesenchymal Stem Cells and their Exosomes on Experimentally Induced Diabetic Retinopathy in Rats: Histological and Immunohistochemical Study

Background: Diabetic retinopathy (DR) is one of the most common microvascular complication of diabetes that affects the retina and causes acquired blindness among working-age people. Stem cell therapy and exosomes have become promising therapeutic strategies for DR with the development of modern medical technology in the field of cell therapy. Objective: To evaluate the possible potential therapeutic effect of bone marrow derived Mesenchymal stem cells (BMMSCs) and their exosomes (BMMSCs-exosomes) on induced diabetic retinopathy in rats. Materials and Methods: Ten young rats were used to prepare mesenchymal stem cells (MSCs). Sixty-four adult male albino rats were divided into six groups. Group I (Control group). Group II (affected group): Rats received single intraperitoneal injection of STZ (60 mg/kg body weight), freshly dissolved in citrate buffer. Group III: DR treated with BMMSCs. Group IV: DR treated with BMMSCs-exosomes. Group V: DR treated with BMMSCs and MSCs-exosomes. Group VI (recovery group). Retinal specimens were taken and processed for histological and immunohistochemical examination. Results: Group II and VI displayed decreased retinal thickness, obvious disorganization of the outer segment of photoreceptors, together with cytoplasmic vacuolations in the cells of the inner nuclear and ganglionic layers. Furthermore, there was a significant increase (P < 0.05) in VEGF and vimentin immunoexpression. Groups III and IV showed improvement of some histological microscopic changes described in group II. While, group V displayed histological architecture and ultrastructure near to control group. Conclusion: MSCs and exosomes can treat diabetic retinopathy. However, better results can be obtained when exosomes were given with MSCs. Received: 13 October 2019, Accepted: 03 November 2019
Microbiota of Fresh and Canned Green Table Olives and Antibiotic Resistance of Foodborne Pathogens

Olives are the main part of the healthy, largely vegetarian, Mediterranean diet known to have aquintessential role in prolonging lifespan. All parts of the olive plant leaves, roots, flowers and fruits are rich in beneficial bacteria. Often, during olive processing and storage foodborne bacteria grow and spoil the product. The aim of this study was dual to investigate the microbiota in fresh and canned green table olives, and to test foodborne bacteria isolated from olives for their antibiotic resistance. The presence of pathogens as clostridia, Staphylococci, fecal enterococci, yeasts, Candida spp. and Escherichia coli and coliforms was assessed using selective, differential and chromogenic media. Randomly picked colonies were further subcultured and tested for antibiotic resistance towards 17 antibiotics and six antifungals. Our results showed that fresh olives contained total number of microorganisms (CFU) 3x102, fecal enterococci 2.4x104, Candida – 1.5x102 CFU/g and total number of yeasts and molds 2.3x103. Staphylococci, clostridia and E. coli and coliforms were not detected in fresh olives. In contrast, no bacteria, yeasts and molds, Candida, Staphylococci, clostridia and E. coli and coliforms were observed in canned green olives. Two isolates from fresh olives were further analyzed. They were identified as Enterococcus faecium and Candida krusei. The antibiotic resistance analysis demonstrated resistance of E. faecium 3391 to nine out of 17 antibiotics, including Linezolid, an antibiotic used for treatment of severe infections. C. krusei 3389 showed resistance to two out of six antifungals – to Itraconazole and Fluconazole, belonging to the class of triazole compounds.
EFFECT OF LONG-TERM MINIMUM TILLAGE PRACTICES ON SOME PHYSICAL PROPERTIES OF A CHERNOZEMIC CLAY LOAM

This study was conducted to compare the long-term (20 yr) effects of conventional tillage, minimum tillage and no-till on various soil-water related properties within the tilled layer (0–30 and 30–60 mm) and immediately below the tilled layer (90–120 mm) under a spring cereal-summerfallow rotation cropping system. Parameters measured included saturated hydraulic conductivity, saturation percentage, plant-available water-holding capacity, large pore porosity, bulk density, and infiltration rate of the soil. Tillage treatment effects on these soil properties in each of the four sampling periods were not significantly different. The confidence interval test showed some temporal changes in these soil physical properties, of which hydraulic conductivity was the most affected. In the summerfallow field, regardless of the previous cereal crops, the steady infiltration rate was significantly lower in the soil under conventional tillage than with that under no-till. The results indicate that the surface soil struc.

The mean IgG (6.3±5.1) of patients with ectopic pregnancy was found to be significantly higher than mean IgG (2.8±1.1) for normal pregnant patients (P-value 0.01) and IgM mean (4.5±2.4) of patients with ectopic pregnancy was significantly higher than mean IgM (1.6±1.2) for normal pregnant patients with P-value 0.01. In conclusion, infection of Chlamydia Trachomatis has a significant relationship with the development of ectopic pregnancy therefor screening and treatment of Chlamydia infection may reduce ectopic pregnancy rate with low cost
Plant diversity and community analysis of Gesha and Sayilem Forest in Kaffa Zone, southwestern Ethiopia

Addi A, Soromessa T, Bareke T. 2020. Plant diversity and community analysis of Gesha and Sayilem Forest in Kaffa Zone, southwestern Ethiopia. Biodiversitas 21: 2878-2888. The study was conducted at Gesha and Sayilem districts of the Kaffa Zone with the objective of identifying the floristic compositions, plant community types, and associated environmental factors of the forest. Stratified random sampling technique was used. A total of 90 plots were used to collect vegetation data. The plant community classification was performed using agglomerative Hierarchical cluster analysis Ward’s linkage method was applied in R-software. Species diversity and evenness were evaluated using the Shannon diversity and evenness indices respectively. The study revealed that the study area composed of 300 species that belong to 239 genera in 96 families. Asteraceae was the most abundant family followed by Fabaceae, Acanthaceae, Poaceae, Rubiaceae, and Euphorbiaceae accounting 37%, 15%, 14%, 13%, 12%, and 9% respectively. Five plant community types were identified and these were Ilex mitis-Syzygium guineense, Pouteria adolfi-friedericii-Schefflera abyssinica, Millettia ferruginea-Sapium ellipticum, Arundinaria alpina and Schefflera volkensii-Masea-lanceolata community types. Among the community types, Pouteria adolfi-friedericii-Syzygium guineense community was the most diverse whereas Arundinaria alpina community was the least diverse community. Canonical Correspondence of vegetation data analysis indicated that altitude, disturbance, slope, phosphorus, and the electrical conductivity were the environmental factors that significantly influence the plant communities. The high dependency of local communities on the forest resources is affecting the plant biodiversity. Thus, conservation of the forest through the introduction of sustainable forest management interventions including participatory forest management seems an appropriate action.
Investigating the anti-acne potential of endophytic bacterial extracts isolated from Mangifera casturi in indigenous South Borneo, Indonesia

Endophytic bacteria are beneficial microorganisms living in the tissues system of various parts of a plant, including fruits, leaves, twigs, and roots. The bacteria are stated as forming colonies without causing any damage to the plant. Thus, this study aimed at isolating endophytic bacterial from the leaves, barks, and fruits of Kasturi plant (Mangifera casturi), screening its endophytic bacteria, determining the potential of those endophytic bacteria, identifying 16S rRNA and analyzing potential growth of the bacteria. The isolated endophytic bacteria appeared to show potential activity against pathogenic bacteria Propionibacterium acnes with disc-diffusion methods. Besides, the observations on bacterial activities showed isolate L2, S2 and F4 isolated from leaves, bark and fruits, respectively, as the most potent producers of antibacterial compounds. Technically, those activities were indicated by the formation of clear zones. Molecular identification was investigated by applying PCR amplification on 16S rRNA gene. Furthermore, the isolate L2 was identified as Enterobacter cloacae with 99% sequence similarities; however, isolates S2 and F4 were identified as Escherichia coli. Therefore, these findings suggested that the identified strains would contribute to any further searches for new sources of anti-acne substances. *Corresponding author: E-mail: sogandi@uta45jakarta.ac. id
Accounting for Climate Change Implications of Deforestation: The case of Forest Reserves in Osun State, Nigeria

Deforestation has exacerbated the greenhouse gas emission and the consequent impact on climate change. Development efforts in the last five decades, has led to increased degradation of the environment. Forests play a crucial role in ameliorating the impact of greenhouse gases emitted by industries and households. This study examined the prevalence of deforestation, as an indication of environmental service base loss, and identified the nature of climate change impacts occurring in Osun State forests. Contingent Valuation Model (CVM) using the Willingness to Pay (WTP) was adopted to assess the climate change dimensions of deforestation and provide values for accounting purposes. Survey of stakeholders around the forest reserves in Osun State, Nigeria was undertaken. Data gathered and analysed showed that over 18,000 hectares of original forest reserves were deforested with a prevalence of 38.3%, growing at about 4.76%. There was significant difference in respondents’ average WTP for carbon balance (N3,682.74) and greenhouse gases reduction (N3,573.68) at p < 0.05. It was concluded that deforestation is prevalent in the forest reserves of Osun state, Nigeria. The impacts of deforestation measured through CVM provides basis for modelling climate change implications for accounting purposes. It was recommended that tree planting should be accelerated while the activities of those who convert wood to charcoal should be discouraged. Conscious effort to boost carbon sequestration should be encouraged through expansion of forests.
University of Groningen F-18-FDG PET/CT Scans Can Identify Sub-Groups of NSCLC Patients with High Glucose Uptake in the Majority of Their Tumor Lesions

Background: Reprogrammed glucose metabolism is a hallmark of cancer making it an attractive therapeutic target, especially in cancers with high glucose uptake such as non-small cell lung cancer (NSCLC). Tools to select patients with high glucose uptake in the majority of tumor lesions are essential in the development of anti-cancer drugs targeting glucose metabolism. Type 2 diabetes mellitus (T2DM) patients may have tumors highly dependent on glucose uptake. Surprisingly, this has not been systematically studied. Therefore, we aimed to determine which patient and tumor characteristics, including concurrent T2DM, are related to high glucose uptake in the majority of tumor lesions in NSCLC patients as measured by 2-deoxy-2-[fluorine-18]fluoro-D-glucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) scans. Methods: Routine primary diagnostic 18F-FDG PET/CT scans of consecutive NSCLC patients were included. Mean standardized uptake value (SUVmean) of 18F-FDG was determined for all evaluable tumor lesions and corrected for serum glucose levels according to the European Association of Nuclear Medicine Research Ltd guidelines. Patient characteristics potentially determining degree of tumor lesion glucose uptake in the majority of tumor lesions per patient were investigated. Results: The cohort consisted of 102 patients, 28 with T2DM and 74 without T2DM. The median SUVmean per patient ranged from 0.8 to 35.2 (median 4.2). T2DM patients had higher median glucose uptake in individual tumor lesions and per patient compared to non-diabetic NSCLC patients (SUVmean 4.3 vs 2.8, P < 0.001 and SUVmean 5.4 vs 3.7, P = 0.009, respectively). However, in multivariable analysis, high tumor lesion glucose uptake was only independently determined by number of tumor lesions ≥1 mL per patient (odds ratio 0.8, 95% confidence interval 0.7-0.9). Conclusions: 18F-FDG PET/CT scans can identify sub-groups of NSCLC patients with high glucose uptake in the majority of their tumor lesions. T2DM patients had higher tumor lesion glucose uptake than non-diabetic patients. However, this was not independent of other factors such as the histological subtype and number of tumor lesions per patient.
