Abstract:

The motivation of this work is formed by the biological behavior of a receptor cell (sensory system). It is modeled as a spring-mass-damper oscillator with a spatial disturbance signal acting on the frame and an inner active element that generates a force acting on the mass. Both the system parameters and the excitation signal are supposed to be unknown. The goal is to achieve a predefined movement of the mass, such as tracking a set point trajectory or stabilization. Thus, a controller is required to act on the system using the control force as input in such a way that the desired behavior is

Abstract:

Jumping mechanisms constitute an important means of resolution in applications such as crossing uneven terrain and space exploration. However, the traditional design mainly uses engineering design thinking, but seldom studies the structural characteristics of organisms themselves and lacks biomimetic research basis, which leads to the difference between jumping mechanism and biological structure and its jumping ability. On the other hand, it lacks in-depth study on biological jumping mechanism from the view of engineering. Weevil has excellent jumping performance, and its key jumper structure

Siam Weed was introduced to Nigeria in 1937, through the importation of timber species from Sri Lanka. It is now a serious weed of both arable and plantation crops in the country. Efforts to control it through manual, mechanical, chemical and biological means have met with little success. At present, the weed seems uncontrollable and suggestion is made that the new research focus should be on its possible industrial and pharmaceutical uses.

Recent advances in designing metamaterials have demonstrated that global mechanical properties of disordered spring networks can be tuned by selectively modifying only a small subset of bonds. Here, using a computationally efficient approach, we extend this idea to tune more general properties of networks. With nearly complete success, we are able to produce a strain between any two target nodes in a network in response to an applied source strain on any other pair of nodes by removing only ∼1% of the bonds. We are also able to control multiple pairs of target nodes, each with a different indi

Abstract:

Bioluminescence is a common feature in the permanent darkness of the deep-sea. In fishes, light is emitted by organs containing either photogenic cells (intrinsic photophores), which are under direct nervous control, or symbiotic luminous bacteria (symbiotic photophores), whose light is controlled by secondary means such as mechanical occlusion or physiological suppression. The intrinsic photophores of the lantern shark Etmopterus spinax were recently shown as an exception to this rule since they appear to be under hormonal control. Here, we show that hormones operate what amounts to a unique

Eggplant (Solanum melongena Linnaeus) is one of the most economically important vegetable of tropics having hot-wet climate. The key pest, eggplant fruit and shoot borer, Leucinodes orbonalis Guenee found to be most destructive and first ranked threat especially in South Asia, hence become hot issue for research in this region. It inflicts sizeable damage up to 80 percent in terms of fruit and content of vitamin-C. This situation refrained the farmers growing eggplant, hence relevant literature were gleaned and overviews regarding biology and management of borer with supportive facts and figur

This issue contains selected papers from the International IEEE Conference on Computational Cybernetics that took place in August 2003 in Hungary at the site of lake Balaton. Computational Cybernetics is the synergetic integration of Cybernetics and Computational Intelligence techniques. Cybernetics was defined by Wiener as "the science of control and communication, in the animal and the machine". The word "cybernetics" itself stems from the Greek "kybernetes" that means pilot or governor. Thus, the science of computational Cybernetics is especially concerned with the comparative study of auto

AbstractLiquid–liquid phase separation (LLPS) of biopolymers has recently been shown to play a central role in the formation of membraneless organelles with a multitude of biological functions1–3. The interplay between LLPS and macromolecular condensation is part of continuing studies4,5. Synthetic supramolecular polymers are the non-covalent equivalent of macromolecules but they are not reported to undergo LLPS yet. Here we show that continuously growing fibrils, obtained from supramolecular polymerizations of synthetic components, are responsible for phase separation into highly anisotropic

Abstract:

The purpose of this study was to highlight a method of making equipment for the investigation of low frequency bioimpedance. A constant current with an average value of I = 100 µA is injected into the human body via means of current injection electrodes, and the biological signal is taken from the electrodes of electric potential charged with the biopotentials generated by the human body. The resulting voltage, ΔU is processed by the electronic conditioning system.

Nowadays, talking about aesthetic restorations means talking about metal-free ceramics. The changes and contributions in this field in recent years have been so important and revolutionary that there are currently a multitude of ceramic systems. All of them seek a balance between aesthetic, biological, mechanical and functional factors. However, there are considerable differences between them. Therefore, to select the most appropriate ceramic in each case, it is necessary to know the main characteristics of these materials and their manufacturing techniques.

Abstract:

Cotton is one the major Kharif cash crop of India and is also known as ‘White Gold’ or ‘King of fibres’. Being a rainy season, long duration, wide spaced and slow growing crop at initial stage, it is highly sensitive to weed competition. The critical period of crop-weed competition is 15 to 60 days after sowing and during this period the crop suffers from heavy losses in seed cotton yield. Weeds are the major constraints that reduce the crop yields since they compete for the nutrients, moisture, light and space. The losses caused by weeds in cotton ranges from 50 to 85 percent depending upon t

Abstract:

The last five decades of molecular and systems biology research have provided unprecedented insights into the molecular and genetic basis of many cellular processes. Despite these insights, however, it is arguable that there is still only limited predictive understanding of cell behaviours. In particular, the basis of heterogeneity in single-cell behaviour and the initiation of many different metabolic, transcriptional or mechanical responses to environmental stimuli remain largely unexplained. To go beyond the status quo , the understanding of cell behaviours emerging from molecular genetics

Abstract:

Soybean (Glycine max L.) being a rainy season crop, faces severe infestation of kharif weeds. Since the crop suppresses weeds due to its dense canopy at later stages of growth, the control of weeds has received very little attention. Weeds offer severe competition to crops during the early stage of growth. The critical crop weed competition period in soybean varies from 15–45 days after sowing (DAS) depending upon location and prevailing environmental conditions. Weeds cause a 26–84% reduction in the yield depending upon the types and intensity of weeds, besides impairing the quality of the pr

However, very little understanding exists of the biological and functional effects that enzymes have on cells during the process of releasing the native cells from a given tissue. One specific reason for this is that no technology has existed as a nonenzymatic control to compare baseline biology and function for a given processed tissue.

A key aspect in cover crop management is termination before the cash crop is planted. The aim of this study was to assess the effects of termination methods on ground-dwelling arthropods.

Two different crop systems were investigated for two growing seasons; cauliflower was grown in autumn after the termination of a mixture of cowpea, pearl millet, and radish, and tomato was cropped in spring and summer after the termination of a mixture of barley and

Mechanical failure of machine parts, structures, and microelectronic components has a strong negative impact on the safety, security, and productivity of our people. Prevention of these failures is a principal focus of solid mechanics, which uses analysis, experiment, and computation to provide the understanding necessary for failure reduction through improved design, fabrication, and inspection. Experimental mechanics plays a critical role in this effort since it provides the data base for the calculations and the means for testing the validity of proposed theoretical models of failure.
