biofacies and palaeoecology of the limestone of the jahrum formation in the lar area in the southwest of iran (zagros basin) is addressed in this paper. our detailed analysis of biofacies and palaeoecology shows that the jahrum formation in the studied area were deposited in a carbonate open shelf dominated by heterozoan and, subordinately, photozoan skeletal assemblages. based on analysis of l...

Six-yr-long time series of winds, waves, and water velocity from a cabled coastal observatory in 12 m of water reveal the separate dependence of the cross-shelf velocity profile on cross-shelf and along-shelf winds, waves, and tides. During small waves, cross-shelf wind is the dominant mechanism driving the cross-shelf circulation after tides and tidal residual motions are removed. The along-sh...

In this paper we present a dual approximation scheme for the class constrained shelf bin packing problem. In this problem, we are given bins of capacity 1, and n items of Q different classes, each item e with class ce and size se. The problem is to pack the items into bins, such that two items of different classes packed in a same bin must be in different shelves. Items in a same shelf are pack...

effect of calcium chloride on tomato quality and shelf life of petoearly ch, koral and rio grand tomato cultivars were studied at the agricultural and natural resources research center of west azerbaijan, iran over 2002-2003. a calcium chloride solution in 0,0.5% and 1% concentrations was sprayed on the tomatoes three times. the fruit was harvested at the mature green stage and stored in cold s...

in this research, production possibility and shelf life of frying margarine had analyzed. in order, the test was done in factorial form and totally random method. tested factors were different kinds of margarine (counteractive effect between type of oil in oil phase (canola) and different moisture (16-8-4%) as the first factor and time of keeping margarine as the second factor. in this margarin...

all of the food products are required to be packaged due to hygienic regard, storage, suitable transportation and preservation of quality and vacuum packaging is one of the prevention methods of spoilage. hence in this study, some of the quality factores changes of rutilus frissi kutum fillets storaged in vacuum and air packages were examined during 18 days in ice alike total volatile base-nitr...

Tomato is one of the sensitive fruits to mechanical impacts and physical tensions. The mostmechanical damages arise from handling which results in reducing tomato quality. in this study,impact energy effect has been studied in 3 different levels 0, 0.14 and 0.25 J by a pendulum impactapparatus, on changes of physicochemical properties of tomato, hybrid variety Shiva F1, includingripening factor...

Ice-shelf channels are long curvilinear tracts of thin ice found on Antarctic ice shelves. Many of them originate near the grounding line, but their formation mechanisms remain poorly understood. Here we use ice-penetrating radar data from Roi Baudouin Ice Shelf, East Antarctica, to infer that the morphology of several ice-shelf channels is seeded upstream of the grounding line by large basal o...

A two-dimensional numerical model is used to study the response to upwellingand downwelling-favorable winds on a shelf with a strong pycnocline. During upwelling or downwelling, the pycnocline intersects the surface or bottom, forming a front that moves offshore. The characteristics of the front and of the inner shelf inshore of the front are quite different for upwelling and downwelling. For a...

we examined the effectiveness of intermittent warming (iw), hot water (hw), salicylic acid (sa), and calcium chloride (cacl2) on the postharvest life of pomegranate fruit cv. ‘shishe-kab’ and extending fruit shelf life during cold storage (3°c). fruit were subjected to cycles of 1 d at 17 ± 1°c every 6 d of storage at 3°c under iw conditions. pre-storage treatments were hw (50°c) for 3 min, sa ...
