In a manufacturing environment where a robotic arm is programmed to follow a specified trajectory such as in welding, painting, and soldering, it is often the case that the arm reaches a singular configuration, where the program is stopped, the arm is switched to a new configuration, and the motion is continued. This difficulty has been a long standing problem. This paper presents a mathematica...

Over 3.2 million children worldwide are infected with HIV, but only 24% of these children receive antiretroviral therapy (ART). ART adherence among children is a crucial part of managing human-immunodeficiency virus (HIV) infection and extending the life and health of infected children. Important causes of poor adherence are formulation- and regimen-specific properties, including poor palatabil...

Genomic imprinting is an epigenetic phenomenon causing parent-of-origin specific differential expression of maternally and paternally inherited alleles. While many imprinted genes have been identified in plants, the functional roles of most of them are unknown. In this study, we systematically examine the functional requirement of paternally expressed imprinted genes (PEGs) during seed developm...

The goal of the PRIN2005 “EAH conservation KM system” research project, funded by Italian Ministry of Research, is to establish an advanced integrated approach to conservation of Earthen Architecture Heritage (EAH) that support main design and planning of conservation actions, reducing the technical risk through suitable and compatible measures. Knowledge Management for supporting EAH conservat...

Objective:Privatization is considered as one of the most important components of new public management with its pros and cons. However, privatization has been accepted and implemented as a policy in the whole political and economic system of Iran, but the barriers and dysfunctions of privatization policy implementation has reduced its effectiveness and efficiency in solving the problems of the ...

Although the oral route of drug administration is the most acceptable way of self-medication with a high degree of patient compliance, the intestinal absorption of many drugs is severely hampered by different biological barriers. These barriers comprise of biochemical and physical components. The biochemical barrier includes enzymatic degradation in the gastrointestinal lumen, brush border and ...
