Human-elephant conflict (HEC) threatens the survival of endangered Asian elephants (Elephas maximus). Translocating "problem-elephants" is an important HEC mitigation and elephant conservation strategy across elephant range, with hundreds translocated annually. In the first comprehensive assessment of elephant translocation, we monitored 16 translocations in Sri Lanka with GPS collars. All tran...

The role, effectiveness, and even existence of hospital ethics committees (HECs) are not universally agreed upon. Over the past 20 years, the study of HECs has focused mainly on their structure, scope, and function, making the results more descriptive than anything. In an effort to present study results that could help HECs better serve the needs of their organizations, the authors of this arti...

This paper presents a modeling application of surface runoff using the Hydrologic Modelling System (HEC-HMS). A case study was carried out for the Jianghe watershed, a typical semi-arid and sub-humid geo-climatic region in northern China. Two modeling schemes using different descriptive sub-mechanism models provided by HEC-HMS for runoff volume, direct runoff and routing (channel flow) were inv...

مهمترین پدیده در فرایندهای پوستی زمین جریان آب ها است و رودخانه ها نه تنها در سیمای کلی زمین نقش دارند، بلکه شکل زیستن انسان در کره ی زمین را نیز تعیین می نمایند. تخریب سواحل وتداوم فرسایش کناری هرساله در ایران و سایر نقاط جهان موجب تخریب اراضی مرغوب کشاورزی اطراف رودخانه، تاسیسات ساحلی، پل ها، و امامکن عمومی می گردد. ازسویی اجرای هرگونه عملیات جهت اصلاح مسیر، کنترل فرسایش رودخانه، احداث تاسیسا...

As indicated by Becker and Watts (2001), teaching in economics and finance is still mostly done in a Chalk and Talk passive learning environment. This paper reports on an active, hands-on approach implemented for business students enrolled in an undergraduate course in options and futures at HEC Montréal. The proposed environment adapts and extends the studio approach first developed for Introd...

The complexity of modern scientific software is an important issue that needs to be addressed as part of an effort to revitalize high end computing (HEC). The complexity arises from both the scientific demands and the increasingly complex computers on which the software is run. We believe that HEC software developers need to be able to use a higher level of abstraction to express their computat...

Capillary electrophoresis of lambda double-stranded (ds) DNA (48.5 kbp) in dilute hydroxyethylcellulose (HEC) solutions shows band spreading that cannot be explained by diffusion alone. Dispersion and asymmetry factors of lambda ds-DNA bands were measured as functions of capillary length, HEC concentration and field strength. Band spreading and asymmetry can be explained by a recently developed...

In this study, randomly oriented hydroxyethyl cellulose/polyvinyl alcohol (HEC/PVA) nanofibers were fabricated by electrospinning. The blend solutions of HEC/PVA with different weight ratio of HEC to PVA were prepared using water as solvent to fabricate nanofibers. These nanofibrous scaffolds were coated with bone-like apatite by immersing into 10x simulated body fluid (SBF) for different time ...
