The current research aimed to use non traditional methods to control some stored grain insects. The effects of 180 millitesla (mT) magnetic field (MF) for six different exposure periods (3 min, 30 min, 1 h, 12 h, 24 h and 48 h) on mortality (%) of two stored grain insects, Tribolium casteneum adults and Trogoderma granarium larvae, reduction in F1-progeny (%), seeds germination (%) and seed components (%) after 8 months storage period were studied under laboratory conditions. According to results, the mortality (%) of tested insects increased with increasing of MF time exposure. Trogoderma granarium was more resistant than T. casteneum in which mortality reached 56 and 75%, respectively 14 days after from exposure period. Without any negative effect on seeds germination (%) the MF was very effective in protecting stored wheat from insect infestation up to 8 months compared to non-magnetic seeds which became infested after 3 months of storage. Furthermore, the germination (%) was accelerated by 6 h compared to non-magnetic seeds. The MF level caused a slight increase in the percent of total carbohydrate, crude protein and ash while slightly decrease the percent of moisture, total fats and crude fiber.

The paper describes the impact of two different plant protection products on silkworm ( Bombyx mori L.) development. These products are commonly used in agrotechnical treatments and are officially allowed to use in ecological agriculture. They are also fungicides, which suggests lower negative impact on other groups of organisms. The two used products were Biosept Active Spray (grapefruit extract) and Miedzian 350 SC (copper oxychloride) which were sprayed on mulberry leaves used to feed silkworms from the beginning of the 4th instar. As to measure the level of impact, the mortality of larvae (percentage of dead specimens) and cocoon shell ratio (percentage of shell weight in whole cocoon) were checked. The highest mortality was recorded in the group treated with 0,7% Miedzian solution (92,5%) as well as the lowest shell ratio (12,06) comparing to the control group (mortality 7,5% and shell ratio 17,43). In the Biosept group, no significant mortality was recorded (comparing to the control group) but mean shell ratio showed a significant decrease in the cocoon quality. The study shows that one of the pesticides is highly effective against a non-target organism.

In this paper the new synthesis method for reversible networks is proposed. The method is suitable to generate optimal circuits. The examples will be shown for three variables reversible functions but the method is scalable to larger number of variables. The algorithm could be easily implemented with high speed execution and without big consuming storage software. Section 1 contains general concepts about the reversible functions. In Section 2 there are presented various descriptions of reversible functions. One of them is the description using partitions. In Section 3 there are introduced the cascade of the reversible gates as the target of the synthesis algorithm. In order to achieve this target the definitions of the rest and remain functions will be helpful. Section 4 contains the proposed algorithm. There is introduced a classification of minterms distribution for a given function. To select the successive gates in the cascade the condition of the improvement the minterms distribution must be fulfilled. Section 4 describes the algorithm how to improve the minterms distributions in order to find the optimal cascade. Section 5 shows the one example of this algorithm.

Spleen is highly vascularized organ and bleeding control during partial splenectomy is a big challenge. In this study conventional methods of electrocautery, absorbable suturing and advance methods of topical hemostat Surgicel® were compared to control bleeding during partial splenec- tomy. Twelve healthy dogs (n=4) were divided in A, B and C groups. After partial splenectomy Surgicel®, electrocautery and absorbable horizontal mattress sutures were used to control hemor- rhages in group A, B and C respectively. Bleeding time and loss of blood volume was evaluated during surgery. In addition, blood samples were taken on day 0 pre-surgery and on days 3, 10 and 17 post-surgery to evaluate changes in biochemical parameters after the application of dif- ferent hemostatic techniques. Ultrasonography was also performed at alternative days to check any gross changes in the spleen. Dogs in group A showed minimum bleeding time and loss of blood volume as compared to group B and C. Drop in red blood cells count was compared be- tween group A, B and C showing significant change (p≤0.05) at day 3, 10 and 17, while a sig- nificant decline in hemoglobin was found in group C followed by groups B and A at 3rd and 10th day. There was no difference between platelet counts in various groups. Ultrasonography showed no significant changes in the spleen parenchyma. It was concluded that Surgicel® was an effective material for controlling hemorrhage in veterinary patients.

Objectives: To design and simulate a buck converter and detector circuit which can prognostically indicate the power supply failure. Failure of Aluminium Electrolytic Capacitor (AEC) is considered as the parameter causing the power supply failure. To analyse variation of output ripple voltage due to possible changes in the Equivalent Series Resistance (ESR) and effective capacitance of the capacitor and design a detector to detect the failure of power supply prognostically.
Methods: A DC-DC buck converter in SMPS topology is designed by assuming an input voltage of 12V with 3 volts possible fluctuations and an output voltage of 3.3 volts is desired. Simulation is carried out to measure the variation in output ripple voltage caused due to aging of electrolytic capacitor using TINA by Texas Instruments. A detector is also designed to compare the ripple voltage and a predefined threshold voltage so as to indicate the possible failure of Switched Mode Power Supply (SMPS) well in advance by monitoring the output ripple increase.
Novelty: Having a fault tolerant power supply is very important in safety critical applications. Here by monitoring the output ripple variation, the degradation of AEC is predicted by calculating the ESR and capacitance variation. This simple yet effective prognostic detection will support in the design of fault tolerant power supplies.
Highlight: It is found that, the ripple at the output increases with aging of the electrolytic capacitor, as with time the equivalent capacitance decreases and Equivalent Series Resistance (ESR) of the capacitor increases. The designed detector output is found to prognostically indicate the failure of SMPS.

The article presents a new discretization method of a continuous-time linear model of sensor dynamics. It can be useful to reduce measuring errors related to the inertia of the sensor. For example it is important in the measurement of rapid processes as temperature changes in combustion chambers, or for shortening the time needed to establish the sensor readings in a transition state. There is assumed that sensor dynamics can be approximated by linear differential equation or transfer function. The searched coefficients of equivalent difference equation or discrete transfer function are obtained from Taylor expansion of a sensor output signal and then on the solution of the linear set of equations. The method does not require decomposition of sensor transfer function for zeros and poles and can be applied to the case of transfer function with zeros equal to zero. The method was used to compensate the dynamics of sensor measuring fast signals. The Bode characteristics of a compensator were compared with others derived using classical methods of discretization of linear models. Additionally, signals in time were presented to show the dynamic error before and after compensation.
