This paper presents a method to quantitatively assess the impact of ice-affected hydraulics on hydropower operations using widely used HEC-RAS hydraulic model. The model was identify historical periods where downstream river ice growth reduced net head US Army Corps Engineers dam Pend Oreille River in Idaho, USA. create curves projected stage impacts based border and continuous bank-to-bank ice...

The Larsemann Hills range is an ice-free oasis on the Ingrid Christensen Coast of Princess Elizabeth Land, East Antarctica, which includes Bharti Island, Fisher Island, McLeod Island, Broknes Peninsula, Stornes Peninsula, and several other islands, promontories, and nunataks. The Larsemann Hills is an ice-free area of approximately 50 km2, located halfway between the Vestfold Hills a...

Tree rings from three dendrochronologically dated bristlecone pines were analyzed for stable hydrogen isotopic composition. These trees give a continuous time series from 8000 years ago to the present that indicates the presence of a postglacial climate optimum 6800 years ago and a continuous cooling since then. The qualitative agreement between this record and records from other sources, such ...

The aim of this study was to produce the ice cream with potential antidiabetic effects by addition of pistachio peel extract (PPE) (0, 10, 20 and 30% on dry matter basis). The properties of produced ice creams such as physicochemical, rheological, antioxidant, antidiabetic and sensory properties were evaluated. The results indicated that ice creams containing 20 and 30% of PPE provided desired ...

a generalization of the known results in fusion frames and $g$-frames theory to continuous fusion frames which defined by m. h. faroughi and r. ahmadi, is presented in this study. continuous resolution of the identity (cri) is introduced, a new family of cri is constructed, and a number of reconstruction formulas are obtained. also, new results are given on the duality of continuous fusion fram...

introduction: recently, consumers have directed their interest towards low fat products as they associated them with a reduced risk of well-known health problems such as obesity and coronary heart diseases. fat is a multifunctional ingredient in ice cream system. thus, in attempts to provide desirable flavor and physical characteristics of full fat ice cream, manufactures looking for fat replac...

nonpasturized cream is usually contaminated with different types of pathogens, and its use in foodstuffs such as creamy cake and ice-cream is the main cause of contamination of such foodstuffs. the purpose of the analysis was to show the contamination rate of nonpasturized cream and foodstuffs in which such creams are used. studies carried out on 70 samples from 231 distribution centers, from d...

IIce nucleation active (INA) bacteria are common epiphytic inhabitants that cause frost damage in many plants in the near-zero temperatures. Yet, no studies were found in ice nucleation bacteria associated with pistachio trees. In our earlier study some INA strains were identified and reported. These were assigned as Pseudomonas fragi, P. putida, P. moraviensis and<em...

The subjects of heat transfer and cooling system are very important topics in the Internal Combustion Engines (ICE). In modern cooling systems, low weight, small size and high compactness are the critical designing criteria that requires heat transfer enhancement. Boiling phenomenon which is occurred in the water jacket of the ICE is one of the methods to increase heat transfer in the coolant s...

Following the last glacial maximum (LGM), the demise of continental ice sheets induced crustal rebound in tectonically stable regions of North America and Scandinavia that is still ongoing. Unlike the ice sheets, the Alpine ice cap developed in an orogen where the measured uplift is potentially attributed to tectonic shortening, lithospheric delamination and unloading due to deglaciation and er...
