AbstractHuman endeavours span a wide spectrum of activities which includes solving fascinating problems in the realms of engineering, arts, sciences, medical sciences, social sciences, economics and environment. To solve these problems, classical mathematics methods are insufficient. The real-world problems involve many uncertainties making them difficult to solve by classical means. The researchers world over have established new mathematical theories such as fuzzy set theory and rough set theory in order to model the uncertainties that appear in various fields mentioned above. In the recent days, soft set theory has been developed which offers a novel way of solving real world issues as the issue of setting the membership function does not arise. This comes handy in solving numerous problems and many advancements are being made now-a-days. Jun introduced hybrid structure utilizing the ideas of a fuzzy set and a soft set. It is to be noted that hybrid structures are a speculation of soft set and fuzzy set. In the present work, the notion of hybrid ideals of a near-ring is introduced. Significant work has been carried out to investigate a portion of their significant properties. These notions are characterized and their relations are established furthermore. For a hybrid left (resp., right) ideal, different left (resp., right) ideal structures of near-rings are constructed. Efforts have been undertaken to display the relations between the hybrid product and hybrid intersection. Finally, results based on homomorphic hybrid preimage of a hybrid left (resp., right) ideals are proved.

AbstractWe reviewed retrospectively the clinical and surgical data from 9 children with postoperative chylothorax secondary to cardiac surgery for congenital heart disease seen over a 3 year period. Mean age was 26 months and 6 patients were female. The procedures performed were 2 Blalock-Taussig shunts, 6 Bidirectional Glenn anastomoses and 1 modified Fontan procedure. Diagnosis of chylothorax was made by classical means. The overall incidence of chylothorax was 0.8%, with the relative incidences being 2.5% for Blalock-Taussig, 2.7% for Fontan, and 11.7% for the Glenn procedures. All patients were initially treated conservatively with chest tube drainage and hypercaloric diet suplemented with medium chain triglycerides. Parenteral nutrition was needed in 2 patients, one because of sepsis and the other because of progressive malnourishment. High output fistulas and long periods of drainage were noted after cavo-pulmonary procedures. Up to 12% weight loss was observed in 6 patients, one patient was successfully treated of pneumonia and another died ofPseudomonas aeruginosasepsis. Two patients required chemical pleurodesis because of unabated drainage, with the others being successfully treated conservatively. Chylothorax is a common complication after bidirectional Glenn procedures, and is associated with considerable morbidity and mortality. Earlier operative intervention may be required in these patients. Pleurodesis is a simple, safe, and effective procedure to stop chylous flow.

Goat Farming

Organic farming, as an ecologically acceptable production method based on natural processes and the use of organic and natural materials, is becoming increasingly popular in Serbia. In addition to “organic”, this type of production is also commonly called “ecological” or “biological”. The objectives of organic agriculture are to maintain and increase fertility of the land, suppress land erosion, conserve biodiversity, protect natural resources from pollution and produce foods of high nutritional value. In organizing organic livestock production, priority is given to native (indigenous) breeds adapted to local growing conditions and resistant to diseases. Organic production, which is an integral part of the sustainable agriculture system, does not permit the use of protective and nutraceuticals of synthetic chemical origin and synthetic drugs, growth regulators, hormones and GMOs. Despite the common, classical means of goat farming, in recent years there has been increasing interest to change typical farming methods to introduce “Bio” systems, i.e. biologically clean farming methods. Such production methods result in products free of the chemicals that are common in numerous substances used in common production methods. Animal welfare is always a high priority in organic production. Primarily, animals should be provided with conditions for growth and development that are in compliance with their genetic potential. This implies respecting their physiological and ecological needs, and ensuring conditions to express their natural functions and behaviour. In order to start and later organize such production, certain conditions must be met. The appropriate, accredited institutions are responsible for ensuring that the required conditions are met and that production is in line with the principles of biological production. Holdings meeting the requirements of biological production receive the appropriate certificate. Today organic production in the EU is regulated by the EEC Directive 2092/91, and its amendments.

The diffraction by a conducting wedge of a transient electromagnetic disturbance in the form of a plane wave discontinuity having arbitrary polarization and direction of propagation is reduced to a pair of two-dimensional scalar problems. The solution to one of these is identical with that previously obtained for the analogous acoustical problem, while the second is attacked in a similar manner, using a Tschplygin transformation to reduce the boundary value problem to one in potential theory, which is then solved by classical means.

Classical Means

Specific fractionation of immunologically competent cells derived from normal or immune animals was achieved by filtration through antigen-coated bead columns. This selective retention of the relevant reactive cells could be shown to produce a cell population, which after passage through the column would behave like a suspension rendered immunologically tolerant by "classical" means. The immunologically specific elimination of potential antibody-forming capacity of the filtered cells could be shown to affect the IgM and the IgG system to a similar extent. Analysis of the binding characteristics of the membrane antibodies responsible for this selective retention indicate striking similarities to those of the humoral antibodies produced against the antigen. Thus, the surface receptor could distinguish isolated haptenic groups on a "foreign" carrier background and the receptor of the hapten-reactive cells in the present system (high-rate antibody-forming cells against NIP) failed to combine with carrier specific determinants in analogy with the binding behavior of the serum anti-hapten antibodies. The binding of anti-hapten reactive cells to bead-attached haptens could be specifically inhibited by the presence of free hapten in the columnar fluid during cellular filtration. The results strongly suggest that the potential humoral antibody-forming cell has preformed receptors on its outer surface with binding characteristics, indicating similarity, if not identity, to those of the eventual product of the cell, the humoral antibody.

Quantum sensing exploits the possibility of manipulating single quantum objects and of measuring external physical quantities with unprecedented accuracy. It offers new functionalities that cannot be obtained with classical means. Quantum sensors can be based on atomic vapours, cold atoms, dopants in solid-state materials, etc. In the latter category, the nitrogen vacancy centre in diamond has received particular attention in recent years due to its very attractive characteristics.

Fermionic linear optics is a limited form of quantum computation which is known to be efficiently simulable on a classical computer. We revisit and extend this result by enlarging the set of available computational gates: in addition to unitaries and measurements, we allow dissipative evolution governed by a Markovian master equation with linear Lindblad operators. We show that this more general form of fermionic computation is also simulable efficiently by classical means. Given a system of $N$~fermionic modes, our algorithm simulates any such gate in time $O(N^3)$ while a single-mode measurement is simulated in time $O(N^2)$. The steady state of the Lindblad equation can be computed in time $O(N^3)$.
