OBJECTIVE To evaluate the efficiency of resources allocation and sustainability of the use of netupitant+palonosetron (NEPA) for chemotherapy-induced nausea and vomiting (CINV) prophylaxis assuming the Italian National Health Service (NHS) perspective. A published Markov model was adapted to assess the incremental cost-utility ratio of NEPA compared with aprepitant (APR) + palonosetron (PALO), ...

Retinoids exhibit chemotherapeutic and chemopreventive activities, possibly due to their ability to modulate cell growth, differentiation, and apoptosis. These effects are thought to be mediated by nuclear retinoic acid (RA) receptors (RARs) and retinoid X receptors, each of which includes three subtypes (alpha, beta, and gamma) that act as transcription factors. To determine whether RARs play ...

Scientific high-end computing (HEC) has become an important tool for scientists world-wide to understand problems, such as in nuclear fusion, human genomics and nanotechnology. Every year, new HEC systems emerge on the market with better performance and higher scale. With only very few exceptions, the overall availability of recently installed systems has been lower in comparison to the same de...

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...

به منظور مطالعه و شناسایی ماکروبنتوزهای پایین دست رودخانه زاینده رود، رسوبات مسافتی حدود 160 کیلومتر، از باغ پرندگان تا شهر ورزنه، مورد بررسی قرار گرفت. از این رو، هشت ایستگاه با توجه به نوع بستر انتخاب گردید و نمونه های رسوب به مدت یک سال (1382-1383) توسط نمونه بردار سوربر، اکمن و لوله پولیکا، در هر فصل دو بار نمونه برداری گردید. نمونه ها پس از جداسازی و شمارش، تا حد جنس و در برخی موارد گونه، ...

سیل یکی از پدیده‏های پیچیده و مخرب طبیعی است که هرساله خسارت‌های سنگینی به وجود می‌آورد. از این‏رو، برای اجرای برنامه‏های کنترل سیلاب در بالادست حوضه‏های بزرگ باید چگونگی تأثیر آنها را بر سیلاب حوضه ارزیابی کرد. در تحقیق حاضر به اولویت‏بندی زیرحوضه‏‏ها از نظر سیل‏خیزی در حوضۀ آبخیز چنارسوخته با مساحت 036/141 کیلومترمربع با استفاده از نرم‏افزار HEC-HMS پرداخته ‏شده است. در تحقیق پیش رو پس از تهی...

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...
