In this research, for the first time, valorization of soursop seeds, a poorly studied biomass, was investigated to simultaneously produce oil and proteins within biorefinery approach. A new mild protein extraction method (Pressurized Water Extraction, PWE) developed optimized via response surface methodology compared with conventional alkaline extraction. Furthermore, impact de-oiling technique...
در اکثر کارهای صورت گرفته در زمینه روغنکاری برای حل معادلات حاکم بر جریان (معادلات ناویر-استوکس) از فرض re<<1 استفاده می گردد، که در آن ها ترم اینرسی در مقایسه با لزجت صرفنظر می شود. در بسیاری از موارد، خصوصا در یاتاقان هایی که با سرعت های بالا سروکار دارند. فرض مذکور فرض دستی نخواهد بود. در این پایان نامه، معادلات ناویر-استوکس برای یک یاتاقان لغزنده با در نظر گرفتن هر دو ترم اینرسی و لزجت حل ش...
Ulcerative colitis (UC) is an inflammatory disease affecting the mucosa in colon. Despite significant progress and expansion of therapeutic armamentarium for UC, there are currently no curative medications available some cases require colectomy. In this communication, we report case a 38 years old male patients with five-year history UC who had involvement entire colon was medically refractory....
Walnut (Juglans regia L.) press-cake is a residue of oil processing from which the phenolic compounds were extracted using ethanol 60 % by batch and semi-continuous operations, or ultrasound-assisted maceration in case de-oiled cake, with particular attention to variables time solid-solvent ratio. For extraction, conditions maximizing total yield (TPC) radical scavenging activity evaluated 2,2-...
: The Southern African Foundation for the Conservation of Coastal Birds facility near Cape Town, South Africa, receives ∼900 African Penguins ( Spheniscus demersus) for rehabilitation every year. Data were analyzed from 3,657 adult African Penguins over a 12-yr period (2002-13), and multivariate logistic regression analysis was used to evaluate whether individual history and clinical parameter...
Dramatic Shifts in Benthic Microbial Eukaryote Communities following the Deepwater Horizon Oil Spill
Benthic habitats harbour a significant (yet unexplored) diversity of microscopic eukaryote taxa, including metazoan phyla, protists, algae and fungi. These groups are thought to underpin ecosystem functioning across diverse marine environments. Coastal marine habitats in the Gulf of Mexico experienced visible, heavy impacts following the Deepwater Horizon oil spill in 2010, yet our scant knowle...
Oil pollution is in the forefront ofpublic attention because of the recent series of oil spills from tankers such as the Argo Merchant. Oil spillage frequently destroys the marine flora and fauna; the most striking single effect is the oiling of large numbers of marine birds. For example, as many as 30,000 birds died after the grounding of the Torrey Canyon at Seven Stones Reef, Great Britain i...
among the all parameters affecting the performance of a downhole de-oiling hydrocyclone, the investigation of internal flow field deserves more attempts especially in the petroleum industry. in this study, the effects of inlet flow rate, inlet oil volume fraction, and oil droplet diameter on the separation efficiency and pressure drop ratio have been investigated along the hydrocyclone body. al...
In this article we consider what we have learned from the Exxon Valdez oil spill (EVOS) in terms of when bioremediation should be considered and what it can accomplish. We present data on the state of oiling of Prince William Sound shorelines 18 years after the spill, including the concentration and composition of subsurface oil residues (SSOR) sampled by systematic shoreline surveys conducted ...
The lesser degree of acid-fastness of lepra bacilli as compared with tubercle bacilli appears in a disagreeable manner in the difficulty of demonstrating the organisms of leprosy in paraffinized tissues (1). Faraco (2) showed that by ordinary methods of demonstrating acid-fast organisms the lepra bacilli are often not acid-fast, are not differentiated and may be stained by the counterstain. He ...
