Streszczenie:

The synthesis of nanoparticles using plant extracts has received great attentions during the last two decades. That is plausibly due to its simple, rapid, toxic-free, and efficient reactions. In this study, a unique green method for preparing silver nanoparticles (Ag NPs) using the extract of Qat (or Khat) leaves is reported. The method is cheap, easy and has a potential for mass production of nanoparticles. Qat is a fast growing plant used mostly as stimulant in Yemen and South African countries and contains dozens of phytochemicals in its leaves. These chemicals are extracted from Qat leaves

Khat (Catha edulis (Vahl) Forssk.) is a herb from the Celastraceae family (also known as qat, gaad, or miraa). The leaves and stems are used medicinally and for recreational purposes. The communities that grow khat have identified different varieties based on perceived appearance and quality. This study aimed to evaluate the cytotoxicity of khat varieties grown in the Meru and Embu Counties of Kenya. Field studies were undertaken in the markets and farms in Meru and Embu Counties of Kenya to document and purchase local khat varieties. Dried khat was extracted with a 1:1 v/v MeOH: CH2Cl2 solven

Pain of the tempro-mandibular joint (TMJ) has a direct bearing to missing teeth and excessive physical activity. Consumption of qat requires chewing on the leaves to extract their juice for long hours. A 65-year-old male Yemeni patient, a Qat chewer, reported to the university dental hospital at King Khalid University complaining of pain in left temporomandibular joint with missing mandibular anterior teeth. A multidisciplinary approach for the overall treatment of the patient was decided. Initial treatment was the relief of patient’s pain with the help of a night guard. This was followed by a

Abstract Eosinophil chemotactic activity associated with protein extracts of Taenia taeniaeformis metacestodes was investigated.

When this material was precipitated with ammonium sulfate, activity was present in the 40 to 80% precipitate. Upon rechromatography on QAE cellulose equilibrated in a low ionic strength buffer, eosinophil chemotactic activity was retained by the gel and eluted after application of the NaCl gradient.

Outdoor collector tests are inherently performed under variable weather conditions. Whereas ISO 9806 sets strong restrictions for the conditions of usable data sets for the steady-state collector test SST, EN12975 allows more variable ambient conditions for the quasi-dynamic collector test QDT. This results in shorter collector test times, but could have drawbacks for the uncertainties including the reproducibility of the test results, i.e. the parameters of the collector model. As the weather conditions are never the same within several tests, outdoor collector tests are not repeatable only r

Recently, attention-based Visual Question Answering (VQA) has achieved great success by utilizing question to selectively target different visual areas that are related to the answer. Existing visual attention models are generally planar, i.e., different channels of the last conv-layer feature map of an image share the same weight. This conflicts with the attention mechanism because CNN features are naturally spatial and channel-wise. Also, visual attention models are usually conducted on pixel-level, which may cause region discontinuous problem. In this paper we propose a Cubic Visual Attenti

Each year The Australian Centre for Philanthropy and Nonprofit Studies (ACPNS) at QUT analyses statistics on donations to Deductible Gift Recipients (DGRs), made by Australian individual taxpayers and claimed as deductions in their income tax returns. The information presented below is based on the amount and type of tax-deductible donations made to DGRs and claimed by Australian taxpayers for the period 1 July 2022 to 30 June 2023 extracted from the Australian Taxation Office's (ATO) publication Taxation Statistics 2022–23
