Human dermatosis caused by vesicating beetle products (Insecta), cantharidin and paederin: An overview
Abstract Three major families in the order Coleoptera have been found to produce vesicant toxins, Meloidae (true blister beetles) and Oedemeridae (false blister beetles) produce cantharidin and Staphylinidae (rove beetles) produce paederin. Some of the most important distribution, biological and ecological aspects of these beetle families had been studied because of their products cause human dermatitis. The detection, biosynthesis and chemistry of both cantharidin and paederin were discussed. The prevalence of Paederus dermatitis (skin blistering inflammation) in the world was reviewed. Also, the diagnostic characterization, clinical symptoms of dermatitis and conjunctivitis, the mode of action and pharmacological properties of each vesicant product, preventive measures and curative treatments of the human dermatitis had been included in the present review

The results showed that performance expectancy, facilitating conditions, Social influence, and Trust has a positive and significant impact on BI to use of Mobile Payment. in contrast, the Effort expectancy has an insignificant impact on BI to use M-payment. This study could provide insights that can be valuable for businesses and developers in designing and promoting mobile payment applications that cater to users' preferences and needs
Organizational Justice and Job Satisfaction Among Nurses
Organizations should enhance justice in the workplace to increase the satisfaction among employees. The purpose of this study was to examine the impact of organizational justice on job satisfaction among nurses. The study cohort was composed of nurses from 2 public hospitals. A stratified sampling technique was employed to ensure better representation of samples from the 2 hospitals. A total of 184 valid questionnaires from 2 public hospitals were analyzed by structural equation modeling. The results showed that the 3 dimensions of organizational justice, namely distributive justice, procedural justice, and interactional justice, have a positive and significant impact on the nurses' job satisfaction. Distributive justice showed a greater impact on job satisfaction than procedural justice and interactional justice. The supervisors and administrators should be provided with information on how improvement in organizational justice leads to job satisfaction and on-the-job facilitation of employee innovation. The results of this study provide a clear image for hospital administrations about the substantial role of justice in the workplace
The Relationship between National Culture and Succession Planning in Malaysian Public Universities
This study investigates the role of national culture in succession planning. Higher education institutions ought to learn from corporate succession planning practices; nevertheless, succession planning principles must be adapted as needed to meet the unique needs of each institution. Studies of the influence of culture on succession planning in higher education institutions have not yet revealed the specific impact of national culture on succession planning. We use Hofstede’s national culture dimensions, which are power distance, collectivism, masculinity, uncertainty avoidance and long-term orientation. Data were gathered from five universities in Malaysia, and were analyzed using structural equation modeling. Our findings show that the national culture of university employees influences succession planning. This study contributes to existing understanding of factors affecting succession planning, points towards further research, helps practitioners by demonstrating the importance of taking national culture into account and indicates the importance of implementing succession planning in public universities in Malaysia
THE EFFECT OF JOB SATISFACTION AND ORGANIZATIONAL COMMITMENT ON NURSES’ PERFORMANCE
The purpose: The purpose of this study was to find the impact of organizational commitment and Job satisfaction on nurses’ job performance.
Methodology: The study conducted at the hospital of Ibn al-Athir and employed a quantitative method by structured questionnaires to collect the data. 200 questionnaires were distributed randomly and only 108 valid surveys likewise; the valid questionnaires have been analyzed by SPSS to exam the impact of organizational commitment and job satisfaction on job performance.
Findings: the results indicated there is a positive and significant impact of Job satisfaction on nurses' performance. However, the three components of organizational commitment, Affective Commitment, Continuance Commitment, and Normative Commitment have a positive and significant impact on nurse's performance. The findings of this research indicate that employees ' job satisfaction and organizational commitment components play a critical role in nurses' performance.
Implications: of this study to enrich the body of literature in the context of Iraq, which is suffering from a lack of studies related to nurses' performance.
Novelty: the study provided useful and valuable recommendations to hospitals to increase nurse performance in the context of Iraq
Gravity observations at Sinai Peninsula and its geophysical and geodetic applications
AbstractSouth Sinai is an interesting region from both tectonic and seismological settings. Tectonically, Sinai Peninsula is strongly dominated by its active boundaries due to its location at the triple junction among the Gulf of Suez rift, the Aqaba–Levant transform fault and the Red Sea Rift. Moreover, reported seismological activities along the three tectonic boundaries indicate its continuous activities.It is thus of great interest to delineate the subsurface geological structure responsible of its tectonic settings and its relation to the seismological activity. Therefore, terrestrial gravity observation has been carried out to figure out the sub-surface structure representing its tectonic settings.On the other hand, the location of Sinai Peninsula between Gulf of Suez, Gulf of Aqepa and Red Sea has made the satellite altimetry data an optimum tool to determine the Gravity sources on the marine regions bounding the Sinai region. Finally, temporal gravity variation of the GRACE satellite mission, launched in 2003 gives the opportunity to monitor its temporal gravity variation on regional scale. Temporal gravity variation from GRACE demonstrates any possible mass redistribution along the pounding tectonic settings and its relation to seismicity.Observed gravity map shows significant gravity anomalies attributed to tectonic and seismicity. Satellite altimetry and gravity data are considered to be a valuable source of data to determine the offshore subsurface structure. Temporal gravity variations from GRACE shows important zones of mass redistribution attributed to its new tectonics and its relation to the seismological activities. Integrating all available data sheds more light on the geodynamic behavior of the selected region and its relation to the seismic activities
Effects of georeferencing effort on mapping monkeypox case distributions and transmission risk
<p>Abstract</p> <p>Background</p> <p>Maps of disease occurrences and GIS-based models of disease transmission risk are increasingly common, and both rely on georeferenced diseases data. Automated methods for georeferencing disease data have been widely studied for developed countries with rich sources of geographic referenced data. However, the transferability of these methods to countries without comparable geographic reference data, particularly when working with historical disease data, has not been as widely studied. Historically, precise geographic information about where individual cases occur has been collected and stored verbally, identifying specific locations using place names. Georeferencing historic data is challenging however, because it is difficult to find appropriate geographic reference data to match the place names to. Here, we assess the degree of care and research invested in converting textual descriptions of disease occurrence locations to numerical grid coordinates (latitude and longitude). Specifically, we develop three datasets from the same, original monkeypox disease occurrence data, with varying levels of care and effort: the first based on an automated web-service, the second improving on the first by reference to additional maps and digital gazetteers, and the third improving still more based on extensive consultation of legacy surveillance records that provided considerable additional information about each case. To illustrate the implications of these seemingly subtle improvements in data quality, we develop ecological niche models and predictive maps of monkeypox transmission risk based on each of the three occurrence data sets.</p> <p>Results</p> <p>We found macrogeographic variations in ecological niche models depending on the type of georeferencing method used. Less-careful georeferencing identified much smaller areas as having potential for monkeypox transmission in the Sahel region, as well as around the rim of the Congo Basin. These results have implications for mapping efforts, as each higher level of georeferencing precision required considerably greater time investment.</p> <p>Conclusions</p> <p>The importance of careful georeferencing cannot be overlooked, despite it being a time- and labor-intensive process. Investment in archival storage of primary disease-occurrence data is merited, and improved digital gazetteers are needed to support public health mapping activities, particularly in developing countries, where maps and geographic information may be sparse.</p

Prospecting for Energy-Rich Renewable Raw Materials: \u3cem\u3eAgave\u3c/em\u3e Leaf Case Study
Plant biomass from different species is heterogeneous, and this diversity in composition can be mined to identify materials of value to fuel and chemical industries. Agave produces high yields of energy-rich biomass, and the sugar-rich stem tissue has traditionally been used to make alcoholic beverages. Here, the compositions of Agave americana and Agave tequilana leaves are determined, particularly in the context of bioethanol production. Agave leaf cell wall polysaccharide content was characterized by linkage analysis, non-cellulosic polysaccharides such as pectins were observed by immuno-microscopy, and leaf juice composition was determined by liquid chromatography. Agave leaves are fruit-like--rich in moisture, soluble sugars and pectin. The dry leaf fiber was composed of crystalline cellulose (47-50% w/w) and non-cellulosic polysaccharides (16-22% w/w), and whole leaves were low in lignin (9-13% w/w). Of the dry mass of whole Agave leaves, 85-95% consisted of soluble sugars, cellulose, non-cellulosic polysaccharides, lignin, acetate, protein and minerals. Juice pressed from the Agave leaves accounted for 69% of the fresh weight and was rich in glucose and fructose. Hydrolysis of the fructan oligosaccharides doubled the amount of fermentable fructose in A. tequilana leaf juice samples and the concentration of fermentable hexose sugars was 41-48 g/L. In agricultural production systems such as the tequila making, Agave leaves are discarded as waste. Theoretically, up to 4000 L/ha/yr of bioethanol could be produced from juice extracted from waste Agave leaves. Using standard Saccharomyces cerevisiae strains to ferment Agave juice, we observed ethanol yields that were 66% of the theoretical yields. These data indicate that Agave could rival currently used bioethanol feedstocks, particularly if the fermentation organisms and conditions were adapted to suit Agave leaf composition
