The efficacy of aqueous and emulsifiable formulations of the fungus Metarhizium anisopliae isolate ICIPE78 was evaluated on the population density of Tetranychus urticae infesting common bean plants under screenhouse and field conditions. Synthetic acaricide abamectin was included as a check. Bean plants were artificially infested with T. urticae and allowed to multiply. Three treatments were applied in the screenhouse and 1 treatment in field trials. Mite density was recorded 2 d before spraying and weekly postspraying. The number of pods per plant, number of seeds per pod, and the dry weight of seeds per plant were recorded only in the screenhouse trials. In both screenhouse and field trials, fungal formulations applied at the concentration of 108 conidia/mL and the aearicide reduced the population density of mites as compared to the controls. There were signif- icant differences in T. urticae population densities between the treatments at the various post-spraying sampling dates. In the screenhouse, the mite densities were near zero from 3-week postspraying in the treated leaves. At 4-week postspraying, there were no more leaves in the untreated control （T1） and in the control water ＋ Silwet-L77 （T2）. Fungal formulations were as effective as abamectin in reducing mite densities in both screenhouse and field experiments. There were significant differences in the production parameters during the 2 screenhouse trials, with fungal and abamectin treatments generally having the highest yield. Results of this study underline the potential of the M. anisopliae isolate ICIPE78 as an alternative to acaricides for T. urticae management.

ZnO is nowadays not only used as an additive for the copper and cement industry， but also in medicine and cosmetic industry as part of the substitute materials of choice for the field of new technologies such as renewable energy. This study aims to investigate the effect of iron concentration on the microstructural and structural properties of ZnO for Electrolysis and Photodetector Applications. The Thin layers of un-doped and doped ZnO with different percentages of Fe （2， 4， and 6 wt.%） were deposited by spin-coating on glass substrates. Sample characterization was done by X-ray diffraction （XRD）， Atomic force microscopy （AFM）， Scanning electron microscopy （SEM）， energy-dispersive X-ray spectroscopy （EDS）， UV-visible absorption spectra and X-ray photoelectron spectroscopy （XPS）. Structural measurements by XRD show that all the layers are polycrystalline with a hexagonal Wurtzite structure. Two new peaks were also discovered after the doping process （400） and （440） belonging to the Fe2O4crystal phase spectrum. Morphological analysis showed that the surface roughness values of ZnO layers ranged between 8 and 45 nm. XPS studies confirmed the presence of Fe in +3 states in ZnO layers. An average transmittance of 90% was measured by UV- in the wavelength range of 200-900 nm. The values of the energy gap （Eg） decreased with an increase in the concentration of Fe. AFM topography results confirmed that ZnO-based thin layers have a relatively uniform surface. The efficiency of these samples has been confirmed for their use in many electrical applications， including photodetectors and electrolysis of contaminated solutions.

Background: Thyroid cancer is a rare disease yet the most common endocrine malignancy in pediatrics. Unlike adult patients, children with thyroid nodules typically don’t complain of pain, soreness, or difficulty swallowing. Additionally, using the recommended therapy for adults to treat paediatrics is not appropriate. There is an unmet need for updated unique guidelines for the management of papillary thyroid carcinoma (PTC) in paediatrics and adolescents. Case Report: A 12-year-old girl had an atypical presentation of metastatic PTC in lymph nodes. She was treated initially with hemi-thyroidectomy, followed by total thyroidectomy. A multidisciplinary team followed her up till successful results were found. Conclusion: Due to the difference in pathophysiology between thyroid tumors in children and adults, a unique approach to PTC management is to be implemented. Further trials are required for a better understanding of risk factors, the likelihood of recurrence, and the long-term side effects of the chosen management plan.

Journal of Modern Power Systems and Clean Energy 2023年第6期11卷 1719-1733页

作者： Seyed Ali Arefifar Md Shahin Alam Abdullah hamadi IEEE Department of Electrical and Computer Engineering Oakland UniversityRochesterUSA Department of Energy and Technology Odessa CollegeOdessaUSA School of Engineering and Technology Western Illinois UniversityMacombUSA

The ever-increasing dependence on electrical power has posed more challenges to power system engineers to deliver secure, stable, and sustained energy to electricity consumers. Due to the increasing occurrence of short-and long-term power interruptions in the power system, the need for a systematic approach to mitigate the negative impacts of such events is further manifested. Self-healing and its control strategies are generally accepted as a solution for this concern. Due to the importance of self-healing subject in power distribution systems, this paper conducts a comprehensive literature review on self-healing from existing published papers. The concept of self-healing is briefly described, and the published papers in this area are categorized based on key factors such as self-healing optimization goals, available control actions, and solution methods. Some proficient techniques adopted for self-healing improvements are also classified to have a better comparison and selection of methods for new investigators. Moreover, future research directions that need to be explored to improve self-healing operations in modern power distribution systems are investigated and described at the end of this paper.

Integrated assessment of biochemical responses in Mediterranean crab (Carcinus maenas) collected from Monastir Bay,Tunisia

引用

Journal of Environmental Sciences 2011年第10期23卷 1714-1720页

作者： Jamel Jebali Sana Ben-Khedher Jihene Ghedira Nawel Kamel hamadi Boussetta Laboratory of Biochemical and Environmental Toxicology Higher Institute of AgricultureChott-Mariem4042-SousseTunisia

The biochemical response of Mediteranean Crab （Carcinus maenas） collected at five stations of Monastir Bay and from Kuriat station as control was studied using a set of complementary biomarkers. The catalase, glutathione S-transferase, lactate dehydrogenase, acetycholinesterase activities; and metallothionein and malonediladehyde levels in gills were evaluated. Results revealed differences among sites in relation to each specific biomarker. Hence, a suite of biomarkers can be used to discriminate sampling sites according to types of pollution, reflecting differing conditions of anthropogenic impact. Based on Integrated Biomarker Response, the highest values and critical biochemical alteration were observed at Khniss and Ksibat in response to urban and industrial discharges and the lowest IBR value was found at reference site. The current study has shown clearly that a biomarker-based index is usefulness tool in the monitoring Tunisian coast using C. maenas as sentinel specie. Further studies in progress to investigate the seasonal variations of IBR levels and its relationship to pollutants concentrations in the sediment, gills and digestive gland of Carcinus maenas from Monastir Bay.

Journal of Environmental Sciences 2009年第10期21卷 1467-1472页

作者： Jihene Ghedira Jamel Jebali Zied Bouraoui Mohamed Banni Lassaad Chouba hamadi Boussetta Laboratory of Biochemical and Environmental Toxicology Higher Institute of Agriculture Chott-Mariem 4042 Sousse Tunisia Chemical Laboratory Higher Institute of Marine Sciences and Technology La Goulette Center 2060 Tunisia

The acute effects of commercial formulation of chlorpyrifos-ethyl （Dursban ） and the secondary treated industrial/urban effluent （STIUE） exposure on acetylcholinesterase （ACHE） and butyrylcholinesterase （BuChE） activities in hepatopancreas and gills of Mediterranean crab Carcinus maenas were investigated. After 2 d of exposure to chlorpyriphos-ethyl, the AChE activity was inhibited in both organs at concentrations of 3.12 and 7.82 μg/L, whereas the BuCHE was inhibited only at higher concentration 7.82 μg/L of commercial preparation Dursban~. The exposure of crabs to Dursban （3.12 μg/L） showed a significant decrement of ACHE activity at 24 and 48 h, whereas the BuChE was inhibited only after 24 h and no inhibition for both enzymes was observed after 72 h. Moreover, a significant repression of AChE activity was observed in both organs of C. maenas exposed to 5% of STIUE. Our experiments indicated that the measurement of AChE activity in gills and hepatopancreas of C. maenas would be useful biomarker of organophosphorous （OP） and of neurotoxic effects of STIUE in Tunisia.

Photosynthesis and growth responses of pea Pisum sativum L. under heavy metals stress

引用

Journal of Environmental Sciences 2009年第11期21卷 1552-1556页

作者： Sabrine Hattab Boutheina Dridi Lassad Chouba Mohamed Ben Kheder hamadi Bousetta Laboratory of Biochemistry and Environmental Toxicology Laboratory of Marine Biology National Institute of Sea Sciences and Technologies Lagoulette Technical Centre of Organic Agriculture

The present work aimed to study the physiological effects of cadmium （Cd） and copper （Cu） in pea （Pisum sativum）. Pea plants were exposed to increasing doses of cadmium chloride （CdCl2） and copper chloride （CuCl2） for 20 d. The examined parameters, namely root and shoot lengths, the concentration of photosynthetic pigments and the rate of photosynthesis were affected by the treatments especially with high metals concentrations. The analysis of heavy metals accumulation shows that leaves significantly accumulate cadmium for all the tested concentrations. However, copper was significantly accumulated only with the highest tested dose. This may explain the higher inhibitory effects of cadmium on photosynthesis and growth in pea plants. These results are valuable for understanding the biological consequences of heavy metals contamination particularly in soils devoted to organic agriculture.
