the conversion process of heavy hydrocarbons to the valuable products such as gasoline is an important operation in the oil refineries.one important process is the “fluidized catalytic cracking” (fcc).feed injection in fcc process has an important role in the selectivity and properties of the products.performance of the feed injection system is dependent on the atomizers.the size and contributi...

Studying of climatic elements  are one of the most important factors   influencing on agricultural crops  production and developing of agriculture activities in every region that led to increasing production . by studying of agro climatology  can be determined potential facilities in different areas  and used optimum of  facilities . this research was established  by determining  temperature po...

UNR Sim is a decimal based Von Neumann architecture computing device simulator. Chronologically precedent simulators did not include factors we considered necessary or desirable, each in and of itself. Actualized by these inadvertent omissions, we decided to integrate all the desirable behaviors instantiated in these simulators while either neutralizing or negating their undesirable aspects. Th...

Articles in which nonparametric data envelopment analysis (DEA) is applied to estimate the efficiency based on a network structure usually consider desirable intermediary parts that are first stage’s outputs be used as second inputs. In many real-life situations, parameters include and undesirable outputs. This issue has drawn much attention from DEA researchers recent years. The main motivatio...

Background: Hemorrhagic events are amongst the major adverse effects of injectable anticoagulants such as heparin and enoxaparin. This necessitates close monitoring of their use for clinically relevant drug-drug interactions. Aim: To study the rate of hemorrhagic events, the anatomical site, and the severity of the hemorrhage in patients receiving heparin or enoxaparin in combination with clop...

In this paper, we examine the welfare properties of strategic fragmentation under production subsidies. We first consider a case in which a production subsidy rate is given exogenously. We show that, under the fixed subsidy policy, firms choose fragmentation despite the domestic production being socially desirable. Next, we examine a situation in which the government chooses a production subsid...

Patient safety assessment in anaesthesia increasingly relies on the monitoring of frequent but merely undesirable events, like hypotension. We report on the design and implementation of such a monitoring system, where 8032 patients were included over a three years period. Thirty two 'Significant Anaesthetic Events' were defined and their occurrence was routinely collected for each patient. A to...

BACKGROUND Insights into the effects of energy balance-related parenting practices on children's diet and activity behavior at an early age is warranted to determine which practices should be recommended and to whom. The purpose of this study was to examine child and parent background correlates of energy balance-related parenting practices at age 5, as well as the associations of these practic...
