Assessing the synergistic potential of Sentinel-2 spectral reflectance bands and derived vegetation indices for detecting and mapping invasive alien plant species

Grassland biomes are valuable socio-economic and ecological resources. However, the invasion of grasslands by alien plant species has emerged as one of the biggest threats to their sustainability, management and conservation. Timely, cost-effective and accurate determination of invasive alien plant spatial distribution is paramount for mitigating the adverse effects of alien plants on natural grasslands. Whereas literature on use of optical bands for invasive alien plants detection and mapping is abound, there is paucity in literature on the integration of Vegetation Indices (VIs) and optical reflectance bands in invasive species mapping. Specifically, there is need to test the efficacy of improved and freely available sensors like Sentinel-2 in understanding landscape invasion. Hence, this study sought to assess the efficacy of Sentinel-2’s optical bands and VIs for improving the mapping of American Bramble (Rubus cuneifolius) within a grassland biome. Variable Importance in the Projection (VIP) was used to identify the most influential reflectance bands and VIs, which were then fused at a feature level to determine Bramble spatial distribution. To determine the optimal season for Bramble mapping, seasonal classification accuracies were executed in Support Vector Machine (SVM) learning algorithm and accuracies for Spring, Summer, Autumn and Winter seasons compared. Results show that although the highest overall accuracy was achieved using only optical bands, fused imagery increased overall classification accuracies during spring and autumn i.e. 70% to 73% and 63% to 65%, respectively. However, the fused imagery failed to improve on the benchmark of optical imagery during summer and winter. Findings from this study underline the efficacy of complementing VIs and optical bands in determining the distribution of invasive species within grasslands at specific seasons. Furthermore, this study advocates for the adoption and fusion of freely available new generation satellite imagery such as Sentinel-2 as a cost effective option in landscape mapping.
Comparing Masticatory Efficiency of Mandibular Bar-Supported Overdentures with Different Loading Protocols

Purpose: The study aimed to compare progression of masticatory efficiency associated with mandibular bar-supported overdentures either retained by immediately or delayed loaded two implants.Material and Methods: A total 12 completely edentulous patients with persistent complaints from their complete mandibular dentures were chosen. Each participant received two dental implants of (3.8 mm x 12 mm) bilaterally using computer-guided flapless surgery. The participants were grouped according to the bar attachment design into two equal groups. Group SB: six participants received mandibular overdenture supported by immediately loaded two implants connected with prefabricated SFI-Bar system. Group CB: six participants received mandibular overdentures supported by delayed loaded two implants splinted with conventional cast Co-Cr bar attachment. Glucose extraction method was performed to objectively measure the masticatory efficiency for each patient at different time points including; including; one week after implant-bar connections connections (T0), six months after implant-bar connections (T6), and 12 months after implant-bar connections (T12). Results: There were statistically significant difference of masticatory efficiency between the (SB) and, (CB) (P=.004 and P=.001 respectively). Starting from T0, the findings showed highly statistical significance (P=0.000) in improving the masticatory efficiency at (T6) and (T12) respectively. Conclusion Regardless the limitations of this clinical study, it can be conclude that restoring edentulous patient with mandibular overdenture assisted with bar improves the masticatory efficiency with a noticeable statistical improvement of masticatory efficiency for immediate versus delayed loading protocol.

CD63 EXPRESSION ON BASOPHILS IN PATIENTS WITH ALLERGY TO BETA-LACTAM ANTIBIOTICS BRENDA LEECYOUS FACULTY OF SCIENCE UNIVERSITY OF MALAYA

Immediate-type hypersensitivity reactions to beta-lactam antibiotics are an increasing clinical issue. However, diagnosis is challenging with little information from current available in vivo and in vitro tests. The gold standard test for diagnosis of drug allergy is the risky drug provocation test performed under close clinical supervision. In the current study, we aimed to study the expression of CD63 marker on basophil cells in patients with beta-lactam allergy, thus identify if this test can be useful in preventing misdiagnosis in these patients. We recruited 25 patients with suggestive clinical characteristics of allergy to beta-lactam antibiotics and 25 healthy controls. Skin Prick Test (SPT) using a panel of beta-lactam allergens consists of Penicilloyl-polylysineMinor Determinant Mix (PPL-MDM), Amoxicillin and Clavulanic Acid were carried out in 24 patients. CD63 expression was determined by employing Basophil Activation Test (BAT) using Penicillin G, Penicillin V, Penicilloyl-polylysine (PPL), Minor Determinant Mix (MDM), Ampicillin and Amoxicillin, along with specific IgE quantification by Fluorescence Enzyme Immunoassay (FEIA) using Penicillin G, Penicillin V, Ampicillin and Amoxicillin in all participants. Of 24 patients, one patient was SPT-positive to Amoxicillin and in-house Ampicillin preparation. Two patients were BAT-positive and four patients were FEIA-positive. One patient showed consistent result in BAT and SPT while another patient showed consistent result in BAT and FEIA. We observed fair agreement between BAT and FEIA (Cohen Kappa Index=0.25). Although the agreement between CD63 expression in BAT and FEIA is fair, their diagnostic values are complementary. Despite good specificity, both tests U ive rsi ty of Ma lay a

Information Security Management in Cloud Computing: a case study

Organizations are quickly adopting cloud computing in their daily operations. As a result, spending’s on cloud security solutions are increasing in conjunction with security threats redirecting to the cloud. Information security is a constant race against evolving security threats and it also needs to advance in order to accommodate the cloud computing adaptation. The aim of this thesis is to investigate the topics and issues that are related to information security management in cloud computing environments. Related information security management issues include risk management, security technology selection, security investment decision-making, employees’ security policy compliance, security policy development, and security training. By interviewing three different types of actors (normal employees, IT security specialists, and security managers) in a large ICToriented company, this study attempts to get different viewpoints related with the introduced issues and provide suggestions on how to improve information security management in cloud computing environments. This study contributes to the community by attempting to give a holistic perspective on information security management in the specific setting of cloud computing. Results of the research illustrate how investment decisions directly affect all other covered topics that in turn have an effect on one another, forming effective information security.
Total Phenolic, Flavonoid Contents, and Antioxidant Activities of Fruit, Seed, and Bark Extracts of Zanthoxylum armatum DC

Natural antioxidants present in several medicinal plants are responsible for inhibiting the harmful effects of oxidative stress. These plants contain polyphenols and flavonoids that act as free radical scavengers and reduce oxidative stress and may be an alternative remedy to cure various harmful human diseases. This study aims to quantify the total phenolic and flavonoid contents (TPC and TFC) and antioxidant properties of methanol extracts of fruits, seeds, and bark of an important medicinal and aromatic plant, Zanthoxylum armatum collected from wild and cultivated populations in Nepal. TPC was determined by Folin–Ciocalteu colorimetric method using gallic acid as standard, and various concentrations of the extract solutions were measured at 760 nm. TFC was calculated by aluminum chloride colorimetric assay. Quercetin was used as standard, and the absorbance was measured at 510 nm. The antioxidant potential of the different extracts was estimated by DPPH free radical scavenging assay, and the absorbance was measured at 517 nm. The highest TPC value was 226.3 ± 1.14 mg GAE/g in wild fruits, and the lowest was 137.72 ± 4.21 mg GAE/g in cultivated seeds. Similarly, the highest TFC value was 135.17 ± 2.02 mg QE/g in cultivated fruits, and the lowest was 76.58 ± 4.18 mg QE/g in cultivated seeds. The extracts showed variable antioxidant properties. The fruits exhibited excellent antioxidant properties with IC50 values of 40.62 μg/mL and 45.62 μg/mL for cultivated and wild fruits, respectively. Similarly, the IC50 values of the bark were 63.39 μg/mL and 67.82 μg/mL, respectively, for cultivated and wild samples. And the least antioxidant capacity was shown by the seeds extract with IC50 values of 86.75 μg/mL and 94.49 μg/mL for wild and cultivated seeds, respectively. The IC50 value of the standard ascorbic acid was 36.22 μg/mL. Different extracts of Z. armatum contain considerable amount of phenols and flavonoids, including antioxidant properties, suggesting the potential use of this species in pharmacy and phytotherapy as a source of natural antioxidants.
A study on the effect of atorvastatin on the pharmacokinetic and antidepressant activity of fluoxetine

Background: Polypharmacy is of wide concern in drug interaction. It is the leading cause of adverse drug reaction, and consequently, increasing the possibility of hospitalization and escalating the cost of care. The incidence of coexisting depression and hyperlipidemia in patients is generally managed by providing numerous drugs for a longer period of time. Aims and Objectives: This study was conducted to observe the effect of atorvastatin on pharmacokinetic parameters of fluoxetine in healthy albino rabbits and to find possible interactions of atorvastatin on the antidepressant activity of fluoxetine using animal screening test. Materials and Methods: Two drugs: Fluoxetine and atorvastatin used concurrently were selected. Healthy male albino rabbits were used to determine the effect of atorvastatin on fluoxetine addressing its pharmacokinetic parameters, whereas rats and mice were used to assess the antidepressant activity of fluoxetine. Two animal models were used to determine its antidepressant activity. Forced swim test (FST) and tail suspension test (TST) were employed in exploring antidepressant activity. High-performance liquid chromatography was used to estimate fluoxetine concentration. Results: The concentration of serum fluoxetine showed slight increment after the atorvastatin treatment for 7 days at 2nd, 4th, 8th, 16th, and 24th h. The pharmacokinetic parameters: Area under the curve, area under first-order moment curve, t1/2, and Cmax of fluoxetine varied after atorvastatin treatment for 1 week in healthy albino rabbits. â€˜â€™Furthermore, atorvastatin treatment for a week revealed a reduction in immobility time in rats and mice as shown by the FST and TST respectively. Conclusion: The results revealed the possibility of drug-drug interaction between fluoxetine and atorvastatin.
Converting hotels web site visitors into buyers: how online hotel web assurance seals services decrease consumers’ concerns and increase online booking intentions

Purpose: Despite the increasing utilization of webpages for the purposes of information seeking, customers’ concerns have become a crucial impediment for online shopping. Our study mainly examines the influence of the effectiveness of web assurance seals services (WASS) and customers’ concerns on customer's willingness to book hotels through perceived website trust and perceived value. Design/methodology/approach: A questionnaire was administrated to measure the study variables. Using PLS-SEM approach to analyses the data collected from 860 users of online hotel websites. Findings: The results indicate that WASS influence positively on perceived website trust and negatively on consumers’ concerns. As well as, perceived value and trust play a mediating role in the link between WASS and consumers’ concerns and their intentions. Finally, perceived website trust and perceived value have greater effect on intention to book hotel for low-habit consumers. Research limitations/implications: Our study ignored the cross-culture issue as it concentrates on the customers from developing countries, so further research may need to compare between two or more than two samples from different societies that could give a significant insights. Second, our study stress on the Web assurance seal services (WASS) to predict customers booking intentions that indicates significant results, so further research may need to examine the role of online reviews as a predictor of customers purchase decision as well. Originality/value: To the best knowledge of authors, this is the first empirical research that investigates examines the influence of the effectiveness of web assurance seals services (WASS) and consumers’ concerns on consumers’ intentions through perceived value and trust. This research also investigates the moderating role of habit in the link between perceived website, perceived value and consumers’ intentions.

EFFECT OF FEEDING HELIANTHUS TUBEROSUS (JERUSALEM ARTICHOKE) ON RATIONS NUTRITIVE VALUE AND SOME BLOOD PARAMETERS OF OSSIMI RAMS

The present study was carried out at farm and laboratory of Animal Production Department- Faculty of Agriculture, Fayoum University, Egypt. Helianthus tuberosus in Ossimi rams rations were evaluated through digestibility, feeding values and some blood parameters. Ossimi rams weighed 45±5 kg in average were used to evaluate the rations supplemented by Helianthus tuberosus. The tested rations were D1 (control) composed of 60% concentrate mixture (CM) + 40% wheat straw (WS); D2, 52.5% CM + 7.5% Helianthus tuberosus (HT) +40% (WS); D3, 45% CM +15% HT +40% WS and D4, 30% CM +30% HT +40% WS. The results revealed that Ossimi rams fed rations of D2 and D3 showed higher significantly values (P<0.05) of most digestibility coefficients and feeding values compared with control ration. While, insignificant differences were found between D1 and D4 regarding digestibilities and feeding values. The obtained results of some blood parameters showed the same trend of rations digestibilities. Adding Helianthus tuberosus in the rations of D2 and D3 (7.5 and 15% HT) of Ossimi rams improved nutrients digestibility and feeding values and some blood parameters.
The State of Occupational Health and Safety Management Frameworks (OHSMF) and Occupational Injuries and Accidents in the Ghanaian Oil and Gas Industry: Assessing the Mediating Role of Safety Knowledge

Background. The study examines the mediation effect of safety knowledge in causal the relationship between Occupational Health and Safety Management Frameworks (OHSMF) and occupational injuries and workplace accidents in the Ghanaian Oil and Gas Industry. The study explores different dimensions of occupational health and safety management systems, workplace accidents, and occupational injuries. The study adopted a cross-sectional survey design. A total of 699 respondents through a convenience and purposive sampling technique were selected in three government-owned oil and gas organizations for the study. Correlation, multiple regression analysis, and bootstrapping methods were used for data analysis. The findings of both the regression and correlation analysis indicated that there is a moderately strong negative and significant relationship between Occupational Health and Safety Management Frameworks (OHSMF) and workplace accidents and occupational injuries. Safety knowledge significantly mediates the causal relationship between OHSMF and workplace accidents and injuries. Safety training was found to be a significant predictor of safety knowledge, work-related injuries, and workplace accidents. The negative relationship between OHSMF and workplace accidents and injuries shows that the existing OHSMF are either ineffective or lack the acceptable safety standards to control hazard exposures in the industry. Management must invest in frequent safety training and orientations to improve safety knowledge among workers. The study further recommends government and industry players to extend serious attention towards the promotion and improvement of occupational health and safety management systems in Ghana.
Comparative Effect of Monoculture and Polyculture in Two Species of Clariidae: Heterobranchus longifilis and Clarias gariepinus in Post Fingerlings Growth

In order to improve the production of Clariidae, a study on the type of cultivation of Heterobranchus longifilis and Clarias gariepinus in post fingerlings growth phase was carried out in tanks. It took place from March to May 2018 at the IRAD fish station in Koupa-Matapi (LN: 5o 21 ‘to 5o 58’ and LE: 10o 17 ‘to 11o 02’) west region Cameroon. For this fact 180 fry therefore 90 Heterobranchus longifilis and 90 Clarias gariepinus with an average weight 3.55 ± 0.68 g; 8.46 ± 0.41cm of total length and 7.37 ± 0.30 cm of standard length were used. The 180 fry were divided into three treatments of 60 individuals (T1 treatment: Clarias gariepinus, T2 treatment Heterobranchus longifilis and T3 treatment: Clarias gariepinus + Heterobranchus longifilis). Each treatment was repeated twice. The fish were fed twice per day at a rate of 10% of the ichthyobiomass readjusted each month after control fishing with a feed at 42% crude protein. From the results of this trial, it appears that unlike the higher mortality rates (11.66 ± 2.36%) recorded in monoculture Clarias gariepinus, the highest cannibalism rates were obtained in monoculture of Heterobranchus longifilis (13.33 ± 4.71%). The survival rate was not influenced by the type of culture. Nevertheless, the highest rate (94.44 ± 0.00%) was observed in Heterobranchus longifilis in polyculture. The highest growth values were recorded for C. gariepinus in polyculture and the weakest for H. longifilis in polyculture. For linear growth, the highest values were recorded in C. gariepinus in monoculture. In order to reduce the rate of cannibalism and mortalities in Clarias gariepinus and Heterobranchus longifilis in post fingerlings growth phase, it is preferable to combine these two species.

Suicide trends and characteristics in Brazil

Brazil is the largest and most populous country in South America (in 2002 the population was approximately 175 million). Although life expectancy in Brazil has increased, suicide and other forms of injury-related mortality, such as homicide and accident, have increased as a proportion of overall mortality (Oswaldo Cruz Foundation, 1984; Brazil Ministry of Health, 2001). The suicide rate in Brazil (3.0–4.0 per 100 000 inhabitants) is not considered high in global terms (World Health Organization, 1999). Nevertheless, it has followed the world tendency towards growth: during 1980–2000, the suicide rate in Brazil increased by 21%. Elderly people present the highest suicide rates in absolute numbers, but the alarming finding in the Brazilian data is that the youth population is increasingly dying by suicide (Mello-Santos et al, 2005). This statistic partially confirms a forecast by Diekstra & Guilbinat (1993) that the number of deaths by suicide would dramatically increase over the next decades, mainly in developing countries, including Latin America. In these regions, socio-economic factors (such as an increase in divorce and unemployment and a decrease in religiosity) increase the risk of self-harm. We discuss the reasons for the low suicide rate in Brazil and highlight the socio-economic factors affecting its increase among the youth population in particular.
