Enzyme constraints

Nitrogen is a major essential yield limiting nutrient in crop production, it serves as a constituent of many plant cell components, such as amino acids and nucleic acids. Hence it is important to improve the productivity as maize is an exhaustive crop. The low productivity of maize during kharif season is attributed to a wide range of constraints including the low nitrogen use efficiency.

In order to improve the accuracy of constraint-based metabolic models, several approaches have been developed which intend to integrate additional biological information. Two of these methods, MOMENT and GECKO, incorporate enzymatic (kcat) parameters and enzyme mass constraints to further constrain the space of feasible metabolic flux distributions.

Legumes are well recognized for their nutritional and health benefits as well as for their impact in the sustainability of agricultural systems. The threatening scenario imposed by climate change highlights the need for concerted research approaches in order to develop crops that are able to cope with environmental stresses, while increasing yield and quality. During the last decade, some physiological components and molecular players underlying abiotic stress responses of a broad range of legume species have been elucidated.

Mixtures of grasslands and perennial woody crops or vineyards represent a major source of potential carbon storage or release. Understanding the spatial variability of soil properties in these ecosystems is important in determining soil constraints related to the management of soil resources.

In the Arab world, men remain twice as likely as women to be users of social media. The barriers to women’s utilization of social media can be divided into two categories: Environmental and Personal. Environmental factors constitute the largest barriers to Arab women’s use of social media, specifically “societal and cultural constraints,” in addition to “access to ICT” and “lack of relevant content for women.” These factors have more to do with the environment in which female social media users operate.

Acomputational approach is used to analyse temporal gene expression in the context of metabolic regulation. It is based on the assumption that cells developed optimal adaptation strategies to changing environmental conditions. Time-dependent enzyme profiles are calculatedwhichoptimize the function of a metabolic pathway under the constraint of limited total enzymeamount.For linearmodel pathways it is shown thatwave-like enzyme profiles are optimal for a rapid substrate turnover.

Investor base: about 70 percent of private bonds were purchased by banks in 2011. Their participation has increased further recently partly because they have faced constraints in expanding consumer loans given increased risk and higher cost in the sector, and therefore have sought alternative higher-yield investment instruments. Liquidity in the secondary market is very limited as many banks tend to hold private bonds until maturity. Retail investors’ participation remains low (see Figure 11). ...

Although there are required evacuation drills, tornado drills, and other drills depending on the area of the country, it has most often been found that there is insufficient communication and collaboration between the first responder community and those in SL/LTC settings. Full evacuations are not often performed due to resource limitations and actual risk to residents in such circumstances.
