Highlights Cleaning cereal grain after harvest is very important for the quality of the product. Technological progress enables the design of new equipment for cleaning cereal grain. Grain segregation allows selecting the best grain to increase yields. The quality of segregation depends on the technological parameters of the device. Abstract. This article presents the results of laboratory tests of a new rotary cleaning device used for the separation and cleaning of barley grain. This device has the characteristics of a multi-stage screen assisted by an air stream (i.e., pneumo-separation). The prototype was constructed at the University of Life Sciences in Lublin, Poland. The tests were conducted on a test stand, which allowed changes in the operating parameters of the cleaning device and their measurement. The tests included determining the influence of the sieve drum inclination angle (a) on the effectiveness and efficiency of barley grain cleaning. The tests were carried out using two drum rotational speeds: 5 rpm and 75 rpm. The quality of the separation and cleaning of barley grain was evaluated using six cleaning process parameters: plump grain separation coefficient (Spg), fine grain separation coefficient (Sfg), fine impurities separation coefficient (Sfi), chaff separation coefficient (Sch), total coefficient of cleaning effectiveness (E), and plump grain cleaning efficiency (qpg). The results showed significant effects of the sieve drum inclination angle on the efficiency and effectiveness of barley grain cleaning.

Effi Ciency

The modifi ed submersible rotating biofi lter MSRB was developed and patented to improve the effi ciency and quality of treated wastewater from small sett lements in Syria by increasing the mass transfer rate and oxygen transfer rate of the drum-type rotating biofi lter without the need for additional aeration elements. The result of comparing the eff ect of two types of biomass carrier on the oxygen transfer rate OTR shows that the highest value of the OTR when using the fi rst biomass carrier (1) was 409 g/m3·h with a drum fi lling percentage of 60%, a rotation speed of 15 rpm and an immersion depth of 35% While the maximum value when using the second biomass carrier (2) was 518.95 g/m3·h with a drum fi lling percentage of 90%, a rotation speed of 15 rpm and an immersion depth of 15%. It can also be concluded that a change in the shape of the biomass carrier, as well as its density, signifi cantly aff ects the OTR of the biofi lter. In addition, changing the shape of the biomass carrier requires changing other technological parameters, such as the fi lling percentage of the drum, the depth of immersion and the rotation speed.

The aim of the study is the quality improvement of the feed mixture prepared and substantiation of the design and technological parameters of blade mixer batch- operated. The task is to set the functional dependence between the prepared mixtures quality and the empirical ratio of the intensity of mixing, taking into account the blades length in regard to values of the rotation frequency and the length of the blade of the batch-operated mixer, as well as the definition of rational length of the mixer blades. Improving the quality of mixture requires both the adding of all nec-essary nutrients and feed components into the volume of prepared portion of the mixture as stipulated by the recipe for mixture, and smooth distribution of components throughout the volume of ready feed. Smooth distribution of the mixture components is related to the design and operation of the mixer. Blade mixer batch- operated is one of the effective types of existing mixers, mixing the ingredients of feed with good quality. The article presents the result oriented design scheme of the blade mixer. Positive functions of the mixture quality and the empirical coefficient of mixing intensity included in their composition are assessed taking into account the length of the blades, depending on the rotation speed and frequency of the mixer. The graphic results of experimental studies taking into account the influence of the blade length and the speed of the mixer on the quality of the prepared mixture are given. The increase of blade length and rotation speed improves the quality of the mixture. Recommended blade length is 75...80 mm. With frequency of rotation increase and the length of the blades the total value of the empirical coeffi-cient of the intensity of mixing, depending on the effect of the length of the blades decreases at a slower pace. This is typical of the obtained hyperbolic dependence.

This article deals with the results of study of species content and basic peculiarities of beaked mites-Phytoseiidae in plant associations of one of the regional centers of Ukraine. The species composition and distribution of mites-Phytoseiidae (Parasitiformes, Phytoseiidae) in plantations of Brovary town of Kyiv region were determined. Fourteen species of 8 genera of phytoseiid mites were found. Index of their existing and relative biotope connection of each registered species to vegetation types and plant species were computed. The study was conducted according to the results of material treatment on the territory of the mentioned city from 25 species of plants (16 species of hardy-shrub and 9 of herbaceous vegetations). The studies of distribution of plant-living mites-Phytoseiidae were conducted separately for hardy-shrub and herbaceous plants). The collection of faunistic material was executed during the vegetation of periods of 2011 and 2013. Within the city the collection of the material was conducted with hardy-shrub plants and herbaceous type of vegetation along the streets, in parks and squares of Brovary city of Kyiv region, district center, one of the satellite-cities of Kiev, the capital of Ukraine. The study of species complexes characteristics of mites was conducted with usage of data calculated on the basis of frequency index (Is), degree of relative habitat confinedness (F) (Pesenko, 1982) and domination index Paliy-Kovnatski (Di) (Shitikov, 2003). Only on one species of plant (F=1) 6 species of mites-Phytoseiidae were found – T.сotoneastri on blue spruce, T. laurae – on common spruce, T. aceri – on ash-leaved maple, P. incognitus – on dog-rose, P. soleiger – on mulberry-tree, A. caudiglans – on sea-buckthorn. These species can be related to stenoecic. The mentioned species are stenotopic only in relation to the sample of plants from the plant associations of Brovary, as in other regions these species of mites can populate the other species of plants. The rest 8 species, being registered on two or more types of plants, are related to euryoecic. Among them there is a group of 6 species with “positive tendencies to population of plants”, owning the indicators of habitat confinedness 0<F<1: A. andersoni (0,92–0,96), A. rademacheri (0,85–0,96), N. herbarius (0,92–0,96), T. tiliarum (0,66–0,77), A. pirianykae (0,73–0,99), A. clavata (0,82–0,98). The rest species, E. finlandicus и K. aberrans, have the expanded range of indicators in relation to habitat confinedness (-0,71<F<0,55 и -0,16<F<0,88), that specifies on their ability to populate the big quality of species. E. finlandicus has the negative indicator of relative habitat confinedness in relation to the plants of herbaceous morphotype that serves confirmation of the ecological peculiarity of the species detected earlier. The data of relative habitat confinedness of mites to certain species of plants shows availability of stenoecic (T.сotoneastri, T. laurae, T. aceri, P. incognitus, P. soleiger, A. caudiglans) and euryoecic species (A. andersoni, A. rademacheri, N. herbarius, E. finlandicus, K. aberrans, T. tiliarum, A. pirianykae, A. clavata).

In this paper we discuss a model to estimate the power consumption and lifetime (LT) of an OLED display based on its pixel value and the brightness setting of the screen (scbr). This model is used to illustrate the effect of OLED aging on display color characteristics. Model parameters are based on power consumption measurement of a given display for a number of pixel and scbr combinations. OLED LT is often given for the most stressful display operating situation, i.e. white image at maximum scbr, but having the ability to predict the LT for other configurations can be meaningful to estimate the impact and quality of new image processing algorithms. After explaining our model we present a use case to illustrate how we use it to evaluate the impact of an image processing algorithm for brightness adaptation.

The article is about the role of the family in the education and formation of children and, especially, in the life and development of autistic children. It describes the problems their family is facing and the need for counseling to parents with autistic children. The reaction to finding the diagnosis of autism varies from one family to another and may encounter a large variety: from disbelief, anger, guilt, helplessness, devastation, surprise, or even rejection of the child, to understanding and relief when finally the parents have an explanation for their child behaviors. Early intervention is important in psychological sustaining of the parent, as parent involvement in the recovery of the child with autism has a determinant role in his development and in ensuring a high quality of life of the child and the life of the hole family. The response to a child's autism diagnosis varies from one family to another. The family goes through a variety of disbelief, anger, guilt, helplessness, devastation, surprise, or even rejection of the child, to understanding and relief. Early intervention is very important in the psychological support of the parent. Because any change disturbs the family equilibrium. A diagnosis of autism changes not only the life of the diagnosed child, but also the life of family members. All the resources are focused on the need of the child. Although each parent is different, after diagnosing the child with autism, all parents are overwhelmed by confusion, shock and denial. Parents' feelings can be influenced by how their children's situation affects different aspects of life - it has an impact on service, on social life and all their personal life. If we look at the family as a system and when a disturbing factor appears, all parts of the system are affected. The involvement of parents in the recovery of the child with autism has a decisive role in its development and in ensuring a high quality of child's life and family life.
