"Prostitution in Cairo"
No full textSelling Sex in the City offers a worldwide analysis of prostitution that takes a long historical approach which covers a time period from 1600 to the 2000s. The overviews in this volume examine sex work in more than twenty notorious “sin cities” around the world, ranging from Sydney to Singapore and from Casablanca to Chicago. Situated within a comparative framework of local developments, the book takes up themes such as labour relations, coercion, agency, gender, and living and working conditions. Selling Sex in the City thus reveals how prostitution and societal reactions to the trade have been influenced by colonization, industrialization, urbanization, the rise of nation states, imperialism, and war, as well as by revolutions in politics, transport, and communication.

Mechanistic insights of hepatoprotective effects of curcumin: Therapeutic updates and future prospects
No full textThe liver is the most essential organ of the body performing vital functions. Hepatic disorders affect the physiological and biochemical functions of the body. These disorders include hepatitis B, hepatitis C, alcoholic liver disease (ALD), nonalcoholic fatty liver disease (NAFLD), liver cirrhosis, hepatic failure and hepatocellular carcinoma (HCC). Drugs related hepatotoxicity is one of the major challenges facing by clinicians as it is a leading cause of liver failure. During post-marketing surveillance studies, detection and reporting of drug-induced hepatotoxicity may lead to drug withdrawal or warnings. Several mechanisms are involved in hepatotoxicity such as cell membrane disruption, initiating an immune response, alteration of cellular pathways of drug metabolism, accumulation of reactive oxygen species (ROS), lipid peroxidation and cell death. Curcumin, the active ingredient of turmeric and exhibits therapeutic potential for the treatment of diabetes, cardiovascular disorders and various types of cancers. Curcumin is strong anti-oxidant and anti-inflammatory effects and thus it possesses hepatoprotective properties. Despite its low bioavailability, its hepatoprotective effects have been studied in various protocols of hepatotoxicity including acetaminophen, alcohol, lindane, carbon tetrachloride (CCL 4 ), diethylnitrosamine and heavy metals induced hepatotoxicities. This report reviews the hepatoprotective effects of curcumin with a focus on its mechanistic insights in various hepatotoxic protocols
Comparing paratransit in seven major African cities: An accessibility and network analysis
No full textAccessibility to transit, together with other important system characteristics such as network coverage and frequency, is a crucial driver of modal choice for urban commuting. In turn, commuting is a major driver of energy consumption and of socio-environmental externalities in cities. So far, few quantitative and comparative assessments of paratransit in cities of Africa have been carried out due to data scarcity and the prevalence of informal services. Here we leverage the recent release of General Transit Feed Specification (GTFS) data to produce comparative metrics of accessibility, network, and service quality of paratransit in seven major cities in sub-Saharan Africa (Abidjan, Accra, Addis Ababa, Freetown, Harare, Kampala, Nairobi). Our results allow for a first-order assessment and comparison of different crucial paratransit characteristics in these cities, shedding light on transport inequality and urban segregation dynamics. The analysis and metrics produced can support transport systems planners in major cities of low-income countries. Further research should focus on approaches for overcoming the residual data limitations and expand the quantitative understanding of paratransit
Multi-scale cross-attention transformer encoder for event classification
No full textWe deploy an advanced Machine Learning (ML) environment, leveraging a multi-scale cross-attention encoder for event classification, towards the identification of the gg→H→hh→bb¯bb¯ process at the High Luminosity Large Hadron Collider (HL-LHC), where h is the discovered Standard Model (SM)-like Higgs boson and H a heavier version of it (with mH>2mh). { In the ensuing boosted Higgs regime, the final state consists of two fat jets. Our multi-modal network can extract information from the jet substructure and the kinematics of the final state particles through self-attention transformer layers. The diverse learned information is subsequently integrated to improve classification performance using an additional transformer encoder with cross-attention heads.} We ultimately prove that our approach surpasses in performance current alternative methods used to establish sensitivity to this process, whether solely based on kinematic analysis or else on a combination of this with mainstream ML approaches. {Then, we employ various interpretive methods to evaluate the network results, including attention map analysis and visual representation of Gradient-weighted Class Activation Mapping (Grad-CAM). Finally, we note that the proposed network is generic and can be applied to analyse any process carrying information at different scales.} Our code is publicly available for generic use
Effect of Melia azedarach (Sapindales: Meliaceae) fruit extracts on Citrus Leafminer Phyllocnistis citrella (Lepidoptera: Gracillariidae)
No full textMelia azedarach L. extracts were studied in comparison with selected biorational insecticides against the citrus leafminer Phyllocnistis citrella Stainton under field conditions. Citrus limon (L.) Burm. F. trees were exposed to: Melia extracts of green and mature fruits, Neem oil (30percent a.i.), abamectin (1.8percent a.i.) and control. Two sprays of each treatment (except for Melia mature fruit extract) were executed at 10-d intervals. The live number of the 1st and later (2nd andamp; 3rd) larval instars per leaf were recorded at initial sampling date and at 10-d intervals after each spray application. Results indicated that there were significant differences in the number of live larval instars among treatments. Melia extracts and the two biorationals, neem oil and abamectin, decreased the larvae population significantly to lower numbers than that of the control at 10 days after each spray application. However, the decrease caused by neem oil and abamectin was significantly higher than that of Melia extracts. Thus, these extracts might be considered as potential alternative with other biorational control methods in management of the leafminer. Further research including bioassays is needed to determine the factors responsible for reducing larvae population and whether these Melia extracts can be utilized in future citrus IPM programs as a tool for citrus leafminer management. © 2013 Abou-Fakhr Hammad et al

No full textDue to the character of the original source materials and the nature of batch digitization, quality control issues may be present in this document. Please report any quality issues you encounter to [email protected], referencing the URI of the item.Includes bibliographical references (leaves 38-40).Issued also on microfiche from Lange Micrographics.Two ambient sampling systems were designed and tested for high speed sampling application for a wind speed range of 4.47 m/s to 26.82 m/s. These systems will be used as inlets for sampling of bioaerosol from air. These systems consist of shrouded probes for sampling at higher speeds and omni-directional inlets for low speed ambient sampling. The two systems operate at 780 L/min and 90 L/min. Another system was designed and tested for medium speed ambient sampling. This unit will be used as a reference sampler for speed ranges from zero to 20.12 m/s. This system consists of a Sierra-Andersen SA-246 inlet for sampling at speeds up-to 6.71 m/s (15 mph) and a shrouded probe operating at variable flow rate for sampling in speed range of 6.71 m/s and 20.12 m/s. An aircraft-borne shrouded probe was also tested at wind speeds as high as 50 m/s in an upgraded high speed wind tunnel
Okvir za vzpostavitev in delovanje globalnega logističnega energetskega središča
No full textEnergy is an essential component of our daily lives. Despite the expanded use of new and renewable energy sources, oil and gas remain the primary sources of energy. Recently, oil and gas sources have become more vulnerable due to their limited and uncertain availability, as well as geopolitical issues that threaten the security of their supply chains. As a result, securing energy sources in general and oil and gas in particular at reasonable prices and reliable supplies has become a major global concern. As a result, the establishment and operation of energy hubs along energy transit routes between producing and consuming countries is crucial for the security and sustainability of the energy supply. These energy hubs can facilitate the trade and exchange of energy by offering logistics services such as transportation, storage, processing, and distribution. This means that establishing and operating such energy hubs necessitates some logistics requirements. However, previous studies did not tackle the logistics requirements for establishing and operating energy hubs in a single, comprehensive framework. Accordingly, the purpose of this study is to address the logistics requirements of energy hubs, with a focus on oil and gas, and to develop a comprehensive framework for establishing and operating GLEH through conducting an empirical study on the Egyptian oil and gas industry.
The study was carried out through seven sequential phases. The study conducted a systematic review of the previous literature using the PRISMA flow diagram and visual bibliometric analysis via VOSviewer software to identify the main research gap and develop an integrated theoretical framework for creating and operating a GLEH. The study then adopted mixed research methods to reap the benefits of both qualitative and quantitative methods. The qualitative technique was used to convert the theoretical framework into a practical framework by conducting semi-structured interviews with key stakeholders. The quantitative method was applied to examine the relationships between the variables and validate the study’s hypotheses in the Egyptian context through a survey.
The study set out an applied framework to help establish and operate GLEHs that can improve the security of energy supplies. It also highlighted the key challenges that might face the establishment and operation of GLEHs and suggested strategies to deal with them.
The study would contribute to science by developing a unique and comprehensive framework for establishing and operating GLEHs, considering both theoretical and empirical aspects. At a practical level, the proposed framework can help improve the global energy supply chain and its sustainability, especially for oil and gas. It can also be used as a model by other countries and regions to establish and operate logistics hubs for energy and other sectors. Furthermore, the framework can be used in further research to develop the performance of energy hubs.Energija je bistvena sestavina našega vsakdanjega življenja. Kljub vse večji uporabi novih in obnovljivih virov energije, nafta in plin ostajata primarna vira. V zadnjem času so viri nafte in plina postali ranljivejši zaradi svoje omejene in negotove razpoložljivosti ter geopolitičnih vprašanj, ki ogrožajo varnost njihovih oskrbnih verig. Posledično je zagotavljanje zanesljivih in cenovno ugodnih virov energije postalo globalna problematika. Vzpostavitev in delovanje globalnih logističnih energetskih središč (v nadaljevanju GLEH) vzdolž energetskih tranzitnih poti med državami proizvajalkami in državami porabnicami je ključnega pomena za varnost in trajnost oskrbe z energijo. Energetska središča lahko olajšajo trgovino in izmenjavo energije z zagotavljanjem logističnih storitev, kot so transport, skladiščenje in distribucija. Vzpostavitev in delovanje takih energetskih središč zahteva različne logistične dejavnike. Predhodne raziskave niso obravnavale logističnih zahtev za vzpostavitev in delovanje energetskih središč v celovitem okvirju, zato je namen raziskave obravnavati logistične zahteve energetskih središč s poudarkom na nafti in plinu s ciljem razvoja celovitega okvira za vzpostavitev in delovanje GLEH z izvedbo empirične študije na primeru Egipta.
Raziskava je potekala v sedmih zaporednih fazah. V prvi fazi smo izvedli sistematičen pregled relavantne literature z uporabo diagrama poteka PRISMA in vizualne bibliometrične analize s programsko opremo VOS viewer s ciljem identifikacije glavne raziskovalne vrzeli in razvoja integriranega teoretičnega okvira za vzpostavitev in delovanje GLEH. Sledila je uporaba kvalitativnih in kvantitativnih metod. Kvalitativna metoda je bila uporabljena za pretvorbo teoretičnega okvira v praktični z izvedbo polstrukturiranih intervjujev s ključnimi deležniki. Kvantitativna metoda je bila uporabljena za preučevanje odnosov med spremenljivkami in potrditev hipotez raziskave.
Na podlagi izvedene raziskave je predlagan praktično uporabni okvir kot pomoč pri vzpostavitvi in delovanju GLEH, ki lahko izboljša varnost oskrbe z energijo. Poudarjeni so tudi ključne izzive, s katerimi bi se lahko soočili pri vzpostavitvi in delovanju GLEH, ter predlagal strateške usmeritve za soočenje z njimi.
Doprinos k znanosti predstavlja postavitev edinstvenega in celovitega okvira za vzpostavitev in delovanje GLEH ob upoštevanju tako teoretičnih kot empiričnih vidikov. Na praktični ravni lahko predlagani okvir pomaga izboljšati globalno energetsko oskrbno verigo in njeno trajnost. Predlagani model je uporaben tudi v drugih državah in regijah pri vzpostaviti in delovanju logističnih središč za energetski ali drugi sektor. Poleg tega je okvir mogoče uporabiti v nadaljnjih raziskavah za razvoj učinkovitosti energetskih središč
