Opimization of the main design and operating parameters of the micronization device

The article substantiates the main characteristics of the studied device of micronization in the processing of grain feed by the method of micronization. Here, an experimental micronizer that micronizes feed grain was taken as the object of research. A multi-factor experiment was also conducted to determine the optimal distance of the infrared lamp from the quartz glass and the optimal power of the light flux. The experiments were carried out on an experimental installation equipped with a “Legrand” dimmer, which allowed changing the radiation power of the lamps. For the experiments, a symmetrical Box-Bench plan was selected from a rotatable, composite second tier. The studies were conducted on wheat, barley and velamir.

DESIGN AND IMPLEMENTATION OF ANTI-TANK GUIDED-MISSILE (ATGM) CONTROL SYSTEM USING SEMI-AUTOMATIC COMMAND LINE OF SIGHT (SACLOS) METHOD BASED ON DIGITAL IMAGE PROCESSING

<div><p class="Els-history-head">The Anti-Tank Guided-Missile (ATGM) system has a very important role in the modern battlefield. This system proved its effectiveness in many modern conflicts such as the Syrian Civil War and Nagorno-Karabakh War. The ATGM system has a very simple electronic and mechanism but it has a very high level of accuracy and precision. One of the control methods used in ATGM is SACLOS method. This method tracks missile position by detecting an infrared lamp that is placed on the missile tail. The tracking system sends control signals to the missile as a result of the correction of the missile position when flying. The infrared tracking system in this research was made using a modified OV5647 camera with the addition of a 940 nm narrow bandpass filter. There are 3 cameras with 1x, 8x, and 16x magnifications which are accessed using 3 Raspberry Pi boards. X and y coordinate data of the infrared lamp is sent to the airframe using wireless telemetry. Atmega328 microcontroller process x and y coordinate data into input proportional control. The result of this research is the prototype of an anti-tank missile control system with an infrared tracking instrument capable track a series of 88 infrared LEDs as far as 997.16 meters with a tracking speed of 90.11 FPS. The threshold parameters of image processing using luminance of YUV color space has a range of 240-255. The control parameter Kp=7 is used in wind tunnel testing with airspeed 20 m/s capable of directing airframe motion to the telescope's crosshairs.</p></div>

Analysis of Factors Affecting the Rearing of Early-Weaned Lambs of Dairy Breeds for the Meat Market

Sheep farming makes an important socio-economic contribution to Spain’s rural areas by sustaining farming and employment in less favored regions, but it is a low-profit sector because of high operating and regulatory costs. One possible solution would be to raise for slaughter lambs from dairy sheep that are not required as replacements. However, the early weaning of these lambs and their artificial rearing generally lead to reduced growth rates and high mortalities. In the work presented herein, three housing systems (slat + heating plate, slat + infrared lamp, and deep-litter + infrared lamp) were tested on 763 lambs over an eight-month period in a farm located in Ejea de los Caballeros (Zaragoza, Spain), with a view to reducing mortality during the period of artificial lactation. The effect of the environmental parameters of the lamb housing on the development of the lambs was evaluated by monitoring environmental (temperature, relative humidity, CO2 and NH3) and productive parameters (weight, average daily gain, and deaths). The results suggested that the combination of deep litter with straw bedding and infrared lamp heating would be the most favorable option, as it led to the highest average daily gain and the lowest percentage of deaths. From the study of the relationship of the initial weight with deaths, a prediction curve was obtained, defining the maximum prices to be paid per lamb as a function of their initial weight to guarantee the profitability of the raising process. This may be regarded as a valuable guidance for Spanish sheep farmers, as it can reduce their economic uncertainty.

The effect of infrared lamp therapy on episiotomy wound restorative besides pain relief among post-partum women

Pregnancy and labor are exceptional occasions in women’s lives. Post-delivery is a very decisive period for compassionate woman who had under gone episiotomy which is a throbbing and disquiet procedure during this time. So, the aim of this study was to appraise the effect of infrared lamp therapy on episiotomy wound restorative besides pain relief among post-partum women. Post-partum women who apply infrared lamp therapy on episiotomy display faster wound restorative besides pain relief than those who do not. A non-randomized controlled clinical trial was conducted on 80 post-partum mothers having normal vaginal delivery with episiotomy who were admitted in Maternity ward at the National Medical Institute of Damanhour City. Women were randomly allocated in two groups. Where, every odd number was assigned to control group (receiving only normal routine care) and every even number was assigned to study group (applying infrared lamp therapy and normal routine care). Data were collected through a structured interview schedule, observational checklist for REEDA Scale and self-reported Numerical Pain Rating Scale. Restorative takes place within 4 days and the REEDA total Score was statistically significant. So, the study concluded that, infrared lamp therapy is an appropriate way of management episiotomy wound among women at puerperium. The study recommended that joining infrared therapy as a main part of post-partum instructions for the women for its imperative role in improving quality of life during post-partum period.
