A practical transportation problem for finding the “departure” time at “all source nodes” in order to arrive at “some destination nodes” at specified time for both FIFO (i.e., First In First Out) and Non-FIFO “Dynamic ” Networks is considered in this study. Although shortest path (SP) for dynamic networks have been studied/documented by various researchers, contributions from this present work consists of a sparse matrix storage scheme for efficiently storing large scale sparse network’s connectivity, a concept of Time Delay Factor (TDF) combining with a “general piece- wise linear function” to describe the link cost as a function of time for Non-FIFO links’ costs, and Backward Dijkstra SP Algorithm with simple heuristic rules for rejecting unwanted solutions during the backward search algorithm. Both small-scale (academic) networks as well as large- scale (real-life) networks are investigated in this work to explain and validate the proposed dynamic algorithms. Numerical results obtained from this research work have indicated that the newly proposed dynamic algorithm is reliable, and efficient. Based on the numerical results, the calculated departure time at the source node(s), for a given/specified arrival time at the destination node(s), can be non-unique, for some Non-FIFO networks’ connectivity.

Purpose: vietnam rice has long been a product of international stature. In the commodity export of vietnam, rice always plays as key agricultural commodities, with contributions billions of dollars each year in total export value. It not only contributes to the overall growth of the economy, but also gradually affirms vietnam’s position on the international rice market. According to General Statistics Office, in 2012, vietnam produced 43.7 million tonnes of rice and exported record 8.047 million tonnes of rice, contributing to the total export value of $3.689 million. However, it has not still been commensurate with the value and potential of rice from vietnam. In addition, the fact is that in recent years, although export rice increased sharply, bringing many records for vietnam, it had lower prices than other rice exporting countries (Thailand, India, Pakistan). So what is the cause and solution to enhance competitiveness and promote export of rice products in viet Nam? In the increasingly complex international context, besides socio-economic development, security and national defense, food security has become a matter of international concern. The article first discusses the competitiveness, the value of rice exports and the need to improve competitiveness and export value of rice in the Mekong Delta. Then, there are some solutions proposed to improve the competitiveness and export of rice in the Mekong Delta in the coming time.

“Industry 4.0” term is devoted to the fourth industrial revolution. Over time and by developing different technologies, this term is coming with the new paradigm and technologies, which help to connect the machines, products, and methods as an interconnected system. This paper aims to introduce an analysis and a reflection around the concepts industry 4.0 and their impacts in the actual industrial world. The effects of this digitalization will be investigated on supply chain systems, decision-making processes, and business models. The classic supply chain is evolving into a Network Supply System (NSS) that is an interconnected supply chain with more focus on product and customer expectations. The global value chain process tends to be product-oriented. Smart data make the decisions more dynamic, flexible, and precise. Therefore, every industrial sector has to be adapted to this digital transformation in all aspects. However, the environmental aspects, global warming, and human healthcare issues are the challenge facing industries and human life, which can be like a brake to make efforts to improve digital life and machine technicity. This paper tries to produce a critical analysis of the concept “industry 4.0 revolution” based on different guidelines to show that it is an evolution of the industry coming through the development of several technologies.

Hormonal therapies may play a role in the treatment of bipolar disorder. Preliminary evidence suggests that: 1) tamoxifen has anti-manic properties;2) hormone replacement therapy represents a good augmentation strategy in treatment-resistant peri-menopausal depression;and 3) certain oral contraceptives could prevent menstrual exacerbations of affective symptoms. Potential neurobiological mechanisms of the anti-manic effects of tamoxifen include the inhibition of protein kinase C in addition its anti-estrogenic effects. Estrogen is a serotonergic and adrenergic agonist as well as an agent promoting neurogenesis in the hippocampus through glutamatergic synaptic formation, which may be the basis of its antidepressant activity. Progesterone appears to decrease serotonergic and adrenergic tone and activity, while increasing GABAA receptor activation through its active metabolite allopregnanolone, which may be the basis of its anxiolytic, sedative, and potentially anti-manic properties. Although there is consistency between the evidence for clinical efficacy and neurobiological mechanisms of hormonal treatments, the current state of knowledge relies on studies with several methodological limitations. On the other hand, benefits of hormonal treatment include protection from osteoporosis and several gynecological cancers, as well as safe contraception in a population at-risk for unplanned pregnancy. Nonetheless, hormonal treatments should be reserved for treatment-resistant bipolar depression or mania, or when contra-indications to other psychotropic medications are present. Institution of regular monitoring for medical complications and drug-drug interactions are essential to minimize risks and maximize benefits.

This paper has been done on study kinematic problem of Persian joint in a general way. In this study, instead of using simulation analysis method as in the previous researches, the 3D rotation matrix method is applied to present the relationship of angular velocities of input shaft and output shaft. The result shows that when the angle between intersecting shafts changes from 0 to 135°, the angular velocity is maintained constant. This new result completely matches with analysis from kinematic simulation of this mechanism. The obtained result is an important base to solve dynamic problem in order to develop the applicability of this joint in reality.
