The aim of the experiments reported here was to increase our understanding of the function of the nasal fluid. It is generally accepted that the nasal fluid assists in the humidification of the inspired air. It also assists in the capture of inspired particles such as pollen, preventing them getting lodged in the lungs. It is also known to contain antibacterial substances which keep the nose, nasopharynx Continue reading →
Cascade control is one of the most popular structures for process control as it is a special architecture for dealing with disturbances. However, the drawbacks of cascade control are obvious that primary controller and secondary controller should be tuned together, which influences each other. In this paper, a new Adaptive Cascade Generalized Predictive Controller (ACGPC) is introduced. ACGPC is a method issued from GPC and the inner and outer controllers of a cascade system are replaced by one cascade generalized predictive controller, where both loops model are updated by Recursive Least Squares method. Compared with existing methods, the new method is simpler and yet more effective. It can be directly integrated into commercially available industrial auto-tuning systems. Some examples are given to illustrate the effectiveness and robustness of the proposed method.

This up-to-date overview will look at the rationale for the recommendation of combination products for multi-symptom relief of common cold and flu. Common cold and flu are defined by their multi-symptom nature with data showing a variety of symptoms reported simultaneously each day over the first six days of illness. Multi-ingredient combination products for multi-symptom relief are formulated to safely, simply, and simultaneously treat multiple symptoms when used as directed. Continue reading →
This special issue on “Malnutrition” will be focusing on the latest development in food and nutrition sciences. Malnutrition, caused by an improper or insufficient diet, includes two aspects of nutritional deficiencies or lack and over nutrition. The WHO has reported hunger and related malnutrition as the greatest threat to the world’s public health. The goal of this special issue is to provide a platform for scientists and academicians all over the world to promote, share, and discuss various new issues and developments in this area of malnutrition.
In this special issue, we invite front-line researchers and authors to submit original research and review articles that explore malnutrition. Continue reading →
Native pastures are the main sources of food for ruminants in Northeast Brazil. Considering that animal feeding represents 70% to 80% of total costs, it is justifiable to maximize the use of pastures. Their correct use allows the conversion of structural carbohydrates into proteins of high biological value at a relatively low cost.
Grasses from Brachiaria genus are the basis of animal production in the tropics, allowing extensive areas for livestock Continue reading →
Today the average oil recovery in the world is less than 40%. This means that 60% of the reserves stays in the formation and can’t be extracted using the existing technologies. Thus, development of new technologies for enhanced oil recovery is a very urgent task.
However, there are more and more concerns about the environmental aspect of oil recovery. The technologies which enable the producers Continue reading →
A significant increase in sports-leisure activity events in recent years presents the opportunity to compete in all age categories. Among the many sport varieties, special attention ought to be paid to amateur sports—recreational sports, particularly in the context of the increasing leisure time among the elderly. Recreational sports activities are free of many distortions and Continue reading →
The good and bad of Internet use such as its effects on depression need to be examined over a period of time. Does the use of social media on the Internet affect depression over time and then in what way?
The obesity is the focus of very important scientific researches due to high incidences of this disease in our society. Understanding the metabolism of adipocytes can help in comprehension of this disease. In this work Sex Difference in Lactate Production by Adipocytes from Lean Humans, we investigated the gender differences in lactate production by adipocytes isolated from lean human visceral adipose tissues. We show that adipocytes isolated from lean women produced as Continue reading →
The gymnosperms are a group of plant which produces seeds. There is no ovary wall outside the ovule, and the seeds of these plants are bare. Gymnosperm and angiosperms make up the group of spermatophyte, and the two differ in flows, seeds and fruits. So far, the conifers, the dicotyledons, and the Gnetophytes are the largest groups of living gymnosperms. As one of the most important categories of plant, gymnosperms have great attraction for researchers.
This special issue aims at providing a platform for scientists and academics all over the world to promote, share, and discuss various new issues and developments in the area of gymnosperms. Potential topics included, but are not limited to: Continue reading →
