this paper reviews recent strategies used for increasing specific yield and productivity in high cell density cultures. high cell density cultures offer an efficient means for the economical production of recombinant proteins. however, there are still some challenges associated with high cell density cultivation (hcdc) techniques. a variety of strategies in several aspects including host design...

At the last deglaciation Earth’s largest biome, mammoth-steppe, vanished. Without knowledge of the productivity of this ecosystem, the evolution of man and the glacialeinterglacial dynamics of carbon storage in Earth’s main carbon reservoirs cannot be fully understood. Analyzes of fossils 14C dates and reconstruction of mammoth steppe climatic envelope indicated that changing climate wasn’t a r...

In the high performance computing domain, the speed of execution of a program has typically been the primary performance metric. But productivity is also of concern to high performance computing developers. In this paper we will discuss the problems of defining and measuring productivity for these machines and we develop a model of productivity that includes both a performance component and a c...

This study examined the effect of urbanization on agricultural production in Abia State. Specifically, it categorized the land tenancy status of the farmers, analyzed the effect of urbanization on agricultural productivity and identified the constraints to agricultural productivity. Multistage random sampling technique was used to select the respondents. Primary data collected using structured ...

Applications that are structured around some notion of a " stream " are increasingly prevalent to common computing practices, and there is evidence that streaming media applications already consume a substantial fraction of the computation cycles on consumer machines [6]. Furthermore, stream processing—of voice and video data—is central to a plethora of embedded systems, including hand-held com...

We present the ins and outs of the purely functional, data parallel programming language SaC (Single Assignment C). SaC defines stateand side-effect-free semantics on top of a syntax resembling that of imperative languages like C/C++/C# or Java: functional programming with curly brackets. In contrast to other functional languages data aggregation in SaC is not based on lists and trees, but puts...

Abstract O ur basic aim in this paper concerns the question that if overusing the Information Technology by service and manufacturing firms can increase the total productivity resulting from this kind of technology regarding the Iran's economic structure and conditions. For this purpose, we primarily evaluate the productivity resulting from the rate of firms' use of IT for...

One of the outcomes of DARPA’s HPCS program has been the creation of three new high productivity languages: Chapel, Fortress, and X10. While these languages have introduced improvements in language expressiveness and programmer productivity, several technical challenges still remain in delivering high performance with these languages. In the absence of optimization, the high-level language cons...

Installation of new pipelines is predicted to grow at a rapid rate over the next twenty years, due in part to the increase use worldwide of combined cycle power generation plant using natural gas a fuel. The need to construct large diameter pipelines over long distances has led to an increased demand to improve the productivity of pipeline girth welding. Many novel techniques have been tried in...
