Lebensdauer des räuberischen Marienkäfers Serangium parcesetosum Sicard (Col., Coccinellidae) mit natürlicher und künstlicher Nahrung

The little known ladybird, Serangium parcesetosum SICARD (Col., Coccinellidae) seems to be an important predator of whiteflies. It has found attacking Bemisia tabaci (GENN.) (Hom., Aleyrodidae) (KAPADIA & PURI 1992), Aleurolobus barodensis MASK (PATEL et al. 1996), Aleurothrixus floccosus MASKELL (ABBOUD & AHMAD 1998), Bemisia argentifolii BELLOWS and PERRING (LEGASPI et al. 2001) as well as Dialeurodes citri (ASHMEAD) (YIGIT et al. 2003). However, in Germany the laboratory studies demonstrated that S. parcesetosum is a promising predator of B. tabaci (AL-ZYOUD & SENGONCA 2004; SENGONCA et al. 2004; AL-ZYOUD et al. 2005a, b; SENGONCA et al. 2005). One of the important features for a successful predator is to live for a long period on the prey species and also not feed on the plant in the prey absence. Long longevity accomplished by voraciously feeding of S. parcesetosum adults resulted in a successful control of B. argentifolii (ELLIS et al. 2001). To use this predator successfully in controlling the whiteflies, especially B. tabaci and Trialeurodes vaporariorum WESTWOOD (Hom., Aleyrodidae), it was important to investigate its natural and artificial nutritional sources. However, such knowledge of S. parcesetosum is still insufficient or completely lacking in the literature. Therefore, the present work was directed to study the longevity of S. parcesetosum on natural nutritional sources such as B. tabaci and T. vaporariorum as well as on certain artificial nutritional sources at two different temperatures in the laboratory.Der in der Literatur nur wenig bekannte Marienkäfer Serangium parcesetosum SICARD (Col., Coccinellidae) scheint, ein spezialisierter Prädator der Weißen Fliegen zu sein. Untersuchungen über die Lebensdauer eines Prädators sind eine der wichtigsten Parameter für seine erfolgreiche Verwendung in der biologischen Bekämpfung. Solche Informationen über S. parcesetosum sind bisher in der Literatur allerdings nur unzulänglich bekannt bzw. fehlen vollständig. Folglich war das Ziel dieser Arbeit, bei zwei unterschiedlichen Temperaturen im Labor zu untersuchen, wie lang S. parcesetosum mit Bemisia tabaci (GENN.) bzw. Trialeurodes vaporariorum WESTWOOD (Hom., Aleyrodidae) als Beute sowie mit bestimmten künstlichen Nahrungen überleben kann. Die Ergebnisse zeigten, dass beide Geschlechter von S. parcesetosum auf Baumwolle mit B. tabaci als Beute, mit Ausnahme der Männchen bei 30°C, signifikant länger mit allen anderen Nahrungen lebten. Bei beiden Temperaturen war die Lebensdauer der Weibchen, mit allen untersuchten Nahrungen, signifikant länger als die der Männchen. Sie schwankte bei beiden Geschlechtern von durchschnittlich 94,3 (♂♂) bis 175,4 (♀♀) Tagen bei 18°C bzw. 50,3 (♂♂) bis 92,4 (♀♀) Tage bei 30°C mit den getesteten Nahrungen. Die adulten Weibchen und Männchen von S. parcesetosum konnten für eine beträchtliche Zeit mit künstlichen Nahrungen überleben. Bei beiden Temperaturen war die durchschnittliche Überlebensdauer beider Geschlechter bei einem Angebot von 10%iger Honig-Emulsion als Nahrung signifikant länger als nur mit Baumwollblättern bzw. ohne ein Angebot an Nahrung

Antidote Stocking at Hospitals in North Palestine

Objective: The purpose of this study was to determine the availability and adequacy of antidote stocking at hospitals in north Palestine based on published guidelines for antidote stocking. Methodology: This study is a cross sectional survey of all hospitals at north Palestine (n=11) using a questionnaire which was completed by the director of the pharmacy department at each hospital. The questionnaire was divided into 2 parts. The first part contained a list of 25 antidotes while the second part contained a list of 12 antidotes. This classification is based on the guideline proposed by the British Association for Emergency Medicine (BAEM). The net antidote stock results were compared with the American guidelines as well. Result: The overall availability of each antidote in the first list varied widely from zero for glucagon to 100% for atropine. The number antidotes of the first list that were stocked in the 11 hospitals ranged from 5 to 12 antidotes but none of the hospitals stocked all the 25 antidotes. Additionally, availability of antidotes in the second list varied widely from zero for polyethylene glycol to 100% for dobutamine. The number of antidotes stocked ranged from 5 to 9 but none of the hospitals stocked all the 12 antidotes. Discussion and Conclusion: hospitals in north Palestine do not have adequate stock of antidotes. Raising awareness of the importance of antidotes by education, regular review of antidote storage, distribution plans, and appropriate legislation might provide solutions. Coordination between Palestinian hospitals and the PCDIC at An-Najah National University is also important

The effect of individual factors on the medication error

Medication error is a major issue in healthcare industry and significant efforts have been taken in recent years to comprehend factors that influence errors in medication.Therefore, the present study aims to examine individual factors that contribute to medication errors as perceived by nurses. 255 registered nurses working in different Jordanian public hospitals have been chosen as samples to collect the study data from. They were asked to complete a questionnaire to assess the perceived individual factors, specifically, on nursing mathematical calculation skills and training as well as knowledge on medication treatment as factors contributing to medication errors. The current study found that the nurses’ mathematical calculation skills, training and their knowledge on medication treatment have significant relationship with medication error.This was proven as the study framework is able to explain 45.6% of the total variance.Consequently, it is recommended that healthcare authorities and hospitals in Jordan should focus on nursing knowledge in medication treatment and the nurses’ ability to perform drug calculation in order to improve the medication system in Jordan

Human error in medication administration process

Context: Medication administration errors is continuous problem in hospitals and occur too frequently, error is unavoidable human action, since medication treatment is a risky procedure that deal with human live therefore error in this process can lead to dangerous consequences on patient well-being, traditionally nurses were blamed for those errors and considered as malpractice action since medication treatment is manly performed by nurses. Objectives: The current study examines the conditions that influence medication error in the perspective systemic approach.Methods: reviewing medication error contributing conditions topic is outlined, exploiting different perspective of how error occurs in medication process.Results and conclusion: the present study concluded that system approach permit a comprehensive set of contributing conditions underlying medication error to be recognize and addressed, rather than just adopt individual centered approach, Future studies should examine underlying conditions, in the perception of work practice environment conditions, team work conditions, task related conditions and individual conditions

Over exploitation of groundwater in the centre of Amman Zarqa Basin-Jordan: evaluation of well data and GRACE satellite observations

Jordan faces a sincere water crisis. Groundwater is the major water resource in Jordan and most of the ground water systems are already exploited beyond their estimated safe yield. The Amman Zarqa Basin is one of the most important groundwater systems in Jordan, which supplies the three largest cities in Jordan with drinking and irrigation water. Based on new data the groundwater drawdown in the Amman Zarqa Basin is studied. This basin is the most used drainage area in Jordan. Groundwater drawdown in eight central representative monitoring wells is outlined. Based on almost continuous data for the last 15 years (2000–2015) an average drawdown for the whole basin in the order of 1.1 m·a−1 is calculated. This result is in accordance with results of previous studies in other areas in Jordan and shows that, until now, no sustainable water management is applied. Groundwater management in such a basin presents a challenge for water managers and experts. The applicability of satellite data for estimating large-scale groundwater over exploitation, such as gravity products of the Gravity Recovery and Climate Experiment (GRACE) mission, along with supplementary data, is discussed. Although the size of the basin is below the minimum resolution of GRACE, the data generally support the measured drawdown

The Arab world's contribution to solid waste literature: a bibliometric analysis

BACKGROUND: Environmental and health-related effects of solid waste material are considered worldwide problems. The aim of this study was to assess the volume and impact of Arab scientific output published in journals indexed in the Science Citation Index (SCI) on solid waste. METHODS: We included all the documents within the SCI whose topic was solid waste from all previous years up to 31 December 2012. In this bibliometric analysis we sought to evaluate research that originated from Arab countries in the field of solid waste, as well as its relative growth rate, collaborative measures, productivity at the institutional level, and the most prolific journals. RESULTS: A total of 382 (2.35 % of the overall global research output in the field of solid waste) documents were retrieved from the Arab countries. The annual number of documents published in the past three decades (1982–2012) indicated that research productivity demonstrated a noticeable rise during the last decade. The highest number of articles associated with solid waste was that of Egypt (22.8 %), followed by Tunisia (19.6), and Jordan (13.4 %). the total number of citations over the analysed years at the date of data collection was 4,097, with an average of 10.7 citations per document. The h-index of the citing articles was 31. Environmental science was the most researched topic, represented by 175 (45.8 %) articles. Waste Management was the top active journal. The study recognized 139 (36.4 %) documents from collaborations with 25 non-Arab countries. Arab authors mainly collaborated with countries in Europe (22.5 %), especially France, followed by countries in the Americas (9.4 %), especially the USA. The most productive institution was the American University of Beirut, Lebanon, with 6.3 % of total publications. CONCLUSIONS: Despite the expected increase in solid waste production from Arab world, research activity about solid waste is still low. Governments must invest more in solid waste research to avoid future unexpected problems. Finally, since solid waste is a multidisciplinary science, research teams in engineering, health, toxicology, environment, geology and others must be formulated to produce research in solid waste from different scientific aspects

Bronchial asthma and chronic obstructive pulmonary disease: research activity in Arab countries

BACKGROUND: Chronic respiratory diseases, like bronchial asthma and chronic obstructive pulmonary disease (COPD), are a worldwide health problem. Quantitative and qualitative assessment of asthma and COPD-related research from Arab countries has not been explored and there are few internationally published reports on such field. The main objectives of this study were to analyze research output originating from Arab countries in the field of bronchial asthma and COPD. METHODS: Original scientific articles or reviews published from the 22 Arab countries were screened using specific words pertaining to asthma and COPD using Scopus database and search engine. Research productivity was evaluated based on: (a) total and trends of contribution of each Arab country to asthma and COPD research and (b) journals in which researchers from Arab countries published their research. RESULTS: The total number of original research and review articles published globally about bronchial asthma and COPD was 163,964. The leading country in bronchial asthma and COPD research was United States of America (38,632; 23.56%). Worldwide, Turkey ranked 19th while Israel and Iran ranked 25th and 29th respectively. Among Arab countries, Egypt and Kingdom of Saudi Arabia came on positions 39th and 43rd, respectively. A total of 1,304 documents about bronchial asthma and COPD were published from Arab countries which represents 0.8% of the global research output. Research in bronchial asthma was almost double that in COPD. Research from Arab countries was low and showed a significant increase after 2000. Approximately 12% of research activity in asthma and COPD from Arab countries was published in Saudi Medical Journal, Annals of Saudi Medicine, Eastern Mediterranean Health Journal and Tunisie Medicale. Kingdom of Saudi Arabia, with a total publication of 353 (27.07%) ranked first among the Arab countries while University of Kuwait was the most productive institution with a total of 123 (9.43%) documents. CONCLUSIONS: The present data showed relatively low research productivity about bronchial asthma and COPD in Arab countries. Research output can be improved by investing more in international and national collaborative research projects in the field of asthma and COPD

Intensification of toxic chlorophenolic compounds degradation over efficient microwave-dried silica-doped tetragonal zirconia nanocatalysts

The work aims to evaluate the efficient microwave (MW) drying method of silica-doped tetragonal zirconia nanocatalysts (SZN-M) for intensification of the degradation of toxic chlorophenolic compounds. The catalyst dried under a conventional oven (SZN-O) was also conducted for comparison. The MW drying time was reduced six times and three times less energy was used than the conventional oven drying. The catalysts were characterized by Fourier-transform infrared, X-ray diffraction, electron spin resonance, nitrogen adsorption-desorption analyses, zeta potential, ultraviolet–visible diffuse reflectance spectroscopy and photoluminescence analyses. Compared with SZN-O, the SZN-M possessed a higher number of Si-O-Zr bonds that led to a greater amount of oxygen vacancies, metal defect sites, larger pore size as well as surface area, and hence displayed excellent performance toward the degradation of toxic 2-chlorophenol, 2-CP (92%), while only 67% for the former. The SZN-M achieved to reduce the total organic carbon and biological oxygen demand up to 88% and 89%, respectively, while for SZN-O, the reduction was up to 82% and 84%. The catalysts still remained active after five cycles and are highly capable of degrading various chlorophenolic compounds that could be very beneficial for the wastewater treatment

Osteoporosis is a neglected health priority in Arab World: a comparative bibliometric analysis

Osteoporosis is an important health problem with serious consequences. Evaluation of osteoporosis scientific output from Arab countries has not been explored and there are few internationally published reports on research activity about osteoporosis. The main objectives of this study were to analyze the research output originating from Arab countries and 3 Middle Eastern non-Arab countries, particularly Israel, Turkey and Iran in the field of osteoporosis. Original scientific articles or reviews published from the 21 Arab countries, Israel, Turkey and Iran about “osteoporosis” were screened using the ISI Web of Science database. The time frame for the result was up to year 2012. The total number of original and review research articles published globally about osteoporosis was 43,571. The leading country in osteoporosis research was United States of America (14,734; 33.82%). Worldwide, Turkey ranked 16th while Israel and Iran ranked 24th and 31st respectively. Among Arab countries, Egypt and Kingdom of Saudi Arabia came on positions 41 and 45 respectively. A total of 426 documents about “osteoporosis” were published from Arab countries which represents 0.98% of the global research output. Research about osteoporosis from Arab countries was very low until 2002 and then increased steadily. The total number of citations for osteoporosis documents from the Arab world was 5551 with an average citation of 13.03 per document and an h- index of 35. Thirty (7.04%) documents published from Arab countries about osteoporosis were published in Saudi Medical Journal. Egypt, with a total publication of 117 (27.47%) ranked first among the Arab countries in research about osteoporosis while American University in Beirut was the most productive institution with a total of 47 (11.03%) documents. Compared with other non-Arab countries in the Middle East, the research productivity from the Arab countries was lesser than that from Turkey and Israel but higher than that from Iran. The present data showed low research productivity in osteoporosis field in Arab countries. Research output can be improved by investing in more international and national collaborative research projects in the field of osteoporosis
