Toward food sovereignty and self-sufficiency in Latin America and the Caribbean: opportunities for agricultural complementarity
Authors: Cango Pedro , Ramos-Martín Jesús , Falconí Fander
Published: February 2022

Abstract Food self-sufficiency is a relevant political issue in many countries, developed and developing, particularly to satisfy the internal nutritional needs of the population and face situations in which the prices of basic products are unstable or when a country faces an external shock. Improving resilience involves strengthening local rural communities to meet demand with domestic production. The member countries of Latin America and the Caribbean (LCN) produce enough food to sustain their population and to be one of the world's largest food exporters. From the theoretical discussion and using data from FAO, the research shows that there is a potential to improve food sovereignty and to define food and agricultural policies through agricultural complementarity among the LCN countries. Diverting part of the current trade with third parties to intraregional trade, for products in which the region has a comparative advantage, would mean that LCN countries could save up to 2.7 billion dollars per year, that is, 6.8% of total imports of food in 2018, avoiding the outflow of foreign currency and promoting greater economic integration between countries.

Published: February 2022

ABSTRACT Objective: determining the multidimensional factors associated with the severity of chronic back pain is essential to design appropriate interventions. The objective of this study was to assess the physical and emotional factors associated with the severity of chronic back pain in adults. Method: a descriptive, analytical and cross-sectional study, carried out between November 2017 and December 2018 in Family Health Strategies, with 198 adults with chronic back pain. Pain severity, assessed by the Brief Pain Inventory, was considered the outcome variable; and the pain interference in daily activities (Brief Pain Inventory), physical disability (Roland Morris Disability Questionnaire), quality of life (World Health Organization Quality of Life-Brief) and pain threshold (digital algometer) variables were considered explanatory. A Multivariate Multiple Linear Regression analysis, using the stepwise method with 5% significance, was preformed to establish an explanatory model of pain severity. Results: the mean age was 48.03 years old (standard deviation: 12.41). Most of the participants were women, married and worked. The variables that had a significant and joint impact on pain severity were pain interference in daily activities (parameter: 0.196; p-value<0.001) and in mood (parameter: 0.054; p-value=0.039) and physical domain of quality of life (parameter: -0.032; p-value<0.001). Conclusion: physical factors (pain interference in daily activities and physical domain of quality of life) and emotional factors (pain interference in mood) play an important role in the severity of chronic back pain, which reinforces its multidimensional character.

Wild and trapped: a history of Colombian zoos and its revelations of animal fortunes and State entanglements, 1930s-1990s
Authors: Leal Claudia
Published: February 2022

Abstract This article presents the first history of Colombian zoos and one of the few contributions to the history of these institutions in Latin America. It proposes that in this region’s zoos native animals tended to predominate, signaling the increasing transformation of forests and other native ecosystems into croplands and pasturelands, as well as the growing distance between people and natural environments. Colombian zoos additionally underscore the limitations of the State in its period of most rapid expansion. They reveal how private interests overshadowed the State by providing public amenities, but also how they offered unconventional solutions to certain hurdles of State formation.

In situ chemical remediation using the jet grouting technique: a field test
Authors: Freitag Peter , Reichenauer Thomas G
Published: February 2022

Jet grouting is a technique for delivering oxidising or reducing reagents directly into source zones in heavily contaminated industrial sites. The advantage is a forced mixing of the contaminant and reagent, eliminating various risks posed by an inhomogeneous, layered subsoil. The feasibility of this approach was demonstrated at a former chemical laundry in Zwölfaxing, near Vienna, Austria. After two extensive investigations, two remediation campaigns were conducted with extensive monitoring and sampling in between to study the effects of locally set measures on the overall site. Samples taken from core drillings and liner samples as well as membrane interface probes (MIPs) were examined and compared with data obtained from concentration measurements at observation wells. This contribution demonstrates the effectiveness of jet grouting and presents a novel approach using MIP sounding for assessing remediation success. This sounding technique enables investigating a zone of highly contaminated subsoil before and after the treatment, with measurements directly showing the dechlorination success.

Heat shock protein response during fixed intensity and self-paced exercise in the heat in young, healthy women on oral contraceptives compared with young healthy men
Authors: Onus Katrina , Cannon Jack , Marino Francesco
Published: February 2022

Background: Heat shock proteins respond to a variety of physiological and environmental stresses, including heat stress, ischemia and endotoxic shock. Hormonal changes during the female menstrual cycle can have a thermogenic effect on body temperature. The monophasic oral contraceptive (OC) pill provides low doses of progesterone and oestrogen over the course of the normal menstrual phase. There is little evidence regarding the combined effects of OC on exercise performance and heat stress with respect to heat shock protein response.
Objectives: This study aimed to determine the response of heat shock proteins (Hsp72) during fixed-intensity and self-paced exercise in the heat in young, healthy women on oral contraceptives compared with young healthy men.
Methods: Sixteen physically active men and women performed 30 min fixed-intensity cycling at 50% of maximum workload, followed by 30 min of a self-paced time trial (TT) interspersed by 30 s maximal sprint at 9, 19 and 29 min respectively. Trials were undertaken in cool (20°C; 48±3% relative humidity (RH)) and warm (32°C; 66±2% RH) ambient conditions. Core (Tc) and skin temperature, heart rate (HR) and subjective responses were measured before, during and post exercise.
Results: The distance, mean and peak power output, mean and peak speed during the self-paced time trial showed no difference between the ambient temperatures for men and women. Hsp72 in females was higher than males at all sample points at both 20°C and 32°C, except for pre-exercise at 20°C (p< 0.04). Women also attained a higher Tc than men at the end of the TT in the heat (38.5°C v 37.9°C for women and men, respectively; p<0.03), higher mean HR and perceived exertion.
Conclusion: This study indicates that females who use oral contraceptives (OC) had higher levels of Hsp72 than males when tested under the same environmental conditions.

Bu çalışmada DARPA SUBOFF su altı aracının manevra benzetimlerinde kullanılacak hidrodinamik katsayılarının hesaplanmasında izlenecek yöntem statik sürükleme (İng. static drift) test benzetimleri ile belirlenmiştir. Su altı araçlarının manevralarının belirlenmesinde kullanılan hidrodinamik katsayıların sayısal olarak yeterli doğrulukta elde edilmesi, çözümlemelerde kullanılan çözüm ağı ve türbülans modelleri ile ilişkilidir. Çalışmada ticari yazılım olan ANSYS Workbench yazılımı kullanılmıştır. Uygun çözüm ağı büyüklüğünün belirlenmesi Richardson Extrapolation metoduna dayalı Grid Convergence Index (GCI) yöntemi ile yapılmıştır. Bu yöntemle Spalart Almaras türbülans modeli kullanılarak üç farklı çözüm ağı büyüklüğü ile elde edilen sonuçların etrafındaki ayrıklaştırma hata bandı tahmin edilmiştir. Bunun yanısıra bu çözümler 14 milyon Reynolds sayısında 0 ila 18 derece yana kayma açılarında yapılan testlerin sonuçları ile karşılaştırılmıştır. Eleman sayısındaki artış ile çözümleme sonuçlarının deneysel veriye yaklaştığı gözlenmiştir. Uygun çözüm ağı seçiminin ardından Realizable k-ε ve SST k-ω modelleri ile analizler tekrarlanarak türbülans modeli opsiyonları incelenmiştir. Çalışmanın sonucunda, 18 derece yana kayma açısına kadar bir-denklemli Spalart Almaras türbülas modelinin pratik uygulamalar için uygun olduğu değerlendirilmiştir. Yüksek kayma açılarının ele alınması gereken durumlarda iki-denklemli SST k-ω türbülans modelinin kullanımının tekrar değerlendirilmesi tavsiye edilmektedir.

Published: February 2022

Bu çalışmada ayrık ve birleşik çamur çürütme sistemleri için pazaryeri atıklarının (meyve ve sebze atıkları) çoklu çürütme/stabilizasyon performansı ve stabilize çamur kalitesi araştırılmıştır. Çalışma, laboratuvar ölçekli biyoreaktörlerde üç farklı arıtma çamuru fraksiyonu (primer (PÇ), sekonder (SÇ) ve karışık çamur (KÇ)) için sırasıyla 1,65, 0,40 ve 1,0 kg UKM/m3.gün organik yükleme hızlarında (OYH), 20 gün hidrolik bekleme süresinde (HBS) ve 35°C sıcaklıkta yarı-sürekli olarak yürütülmüştür. Meyve atığı (MA), sebze atığı (SA) veya meyve+sebze atıkları (MSA) farklı ayrışma özelliklerine sahip arıtma çamurlarının (PÇ, SÇ ve KÇ) yanında farklı bileşim ve oranlarda beslenerek MSA ilavesinin etkisi değerlendirilmiştir. Artan OYH seviyelerinde maksimum spesifik metan üretimi (SMÜ) eldesine göre MA ve SA ilavesi için optimum OYH’ları sırasıyla 0,84 ve 0,33-0,44 g UKM/L.gün ve ağırlıkça ilave oranları PÇ, SÇ ve KÇ için sırasıyla % 51, 209 ve 84 olarak elde edilmiştir. SMÜ’de PÇ, SÇ ve KÇ için sırasıyla %12, 25-55 ve 0 ile günlük metan üretiminde %50-75, 250-300 ve 44-66 artış elde edilmiştir. SMÜ’deki artış anaerobik ayrışabilirliğin arttığını gösterirken bu artışın özellikle ayrık çürütme sisteminde ve özellikle dirençli yapılardan oluşan SÇ için elde edilebileceğini göstermiştir. MA’nın artan yüklemesinde SMÜ’de azalma ile reaktör ve stabilize çamur UKM seviyesinde birikim oluşurken, SA’nın artan OYH’nda toksisite gerçekleşmiş ve PÇ çoklu çürütmesinde metanojen aktivitesi üzerinde hasar oluşmuştur. SA, MA’ya kıyasla daha yüksek metana dönüşüm ile daha yüksek ayrışabilirlik özelliği göstermiştir. MA ayrışması pH’ya asitlenme yönünde etki etmiştir. Elde edilen sonuçlar mevcut kentsel AAT’lerinde hem ayrık hem de birleşik çamur çürütme sistemlerinde çoklu besiyeri olarak MA ve SA ilavesinde düşük yükleme hızlarında metan eldesine olumlu yönde etki göstereceğini ortaya koymuştur. SA ve MA ilavesi stabilize çamurların susuzlaşma kabiliyetini düşürmüş, diğer yandan özellikle besin kısıtlılığı ile düşük biyokütle seviyesinde işleyen SÇ çürütmesinde ayrışabilirliği ve biyokütleyi artırma yönünde fayda sağlayarak tarımsal uygulamalara uygun stabilize çamur üretmiştir.

Published: February 2022

A protocol for the metabarcoding of DNA samples using nanopore technology, for the purposes of biomonitoring, biodiversity assessment, DNA-based diet analysis, or other related applications. The protocol is being used in our laboratory for detecting aquatic invasive bivalve species and for measuring biodiversity of fish and other vertebrates from water eDNA samples, as well as for species identification of scats. The key steps are a first PCR to amplify metabarcoding fragments, a 2nd PCR to add indexes (barcodes) to allow pooling of multiple samples, and the preparation of the pool for sequencing on a MinION sequencer. The protocol is adapted from PCR barcoding (96) amplicons (SQK-LSK109) by Nanopore.
Acoustic mechanism and characteristics of corrosion bubble rupture
Authors: Feng Qiu , Yongzhong Bai , Dingrong Qu , Wenwu Chen
Published: February 2022

Bubble rupture is one of the main acoustic emission (AE) sources for corrosion detection and the study of its acoustic characteristics is of great significance for corrosion identification. However, the stress state affects the form of bubble rupture, causing different acoustic characteristics.
In this paper, the acoustic signal characteristics of two forms of bubble rupture and drag phenomena are investigated and the process of bubble rupture both near to and away from the metal surface is studied, mainly through theoretical calculation, numerical simulation and experimentation.
A theoretical model of bubble rupture is established according to the volume of fluid (VOF) method. The finite element method is used to solve the plate displacement at the interface. Stress pulse theory is applied to calculate the AE signal amplitude of the bubble rupture. AE source characteristic
parameters of the bubble rupture are then proposed. The experimental results demonstrate that the two forms of characteristics of the AE signals from corrosion bubble rupture are consistent with theoretical calculation and simulation results.

Authors:   Faculty of Engineering and Technology, Quy Nhon University, Quy Nhon City, Binh Dinh, Vietnam, Khoa Ngo Minh , Tung Doan Duc , Dai Le Van
Published: February 2022

This paper presents an architecture of the Doubly-Fed Induction Generator based on Wind Energy Conversion System (DFIG-WECS) to study with the Low Voltage Ride Through (LVRT) capability. The proposed architecture consists of three main parts namely the wind turbine, electric generator, control systems. The wind turbine and gearbox are modeled by a servo motor driven by using an inverter system. The electric generator uses the Wound Rotor Induction Generator (WRIG). The control system composes of the rotor-side converter (RSC) and the grid-side converter (GSC). The integration of the digital signal processor (DSP) with the Simulink/Matlab software of the vector control scheme is implemented to control both RSC and GSC. Besides, to protect the overcurrent of the generator’s rotor and overvoltage of the DC-link, the crowbar and chopper circuits and the logical scheme between the crowbar and the RSC are also proposed. To approve the control algorithms implemented in DSP as hardware in the loops, the proposed 0.8kW DFIG-WESC system has been performed under the experimental environment considering LVRT requirement in German grid code.
A Scalable Secure Routing Protocol for Managed-Open Mobile Ad-Hoc Networks
Authors:   Information Technology and Computer Engineering Faculty, Palestine Polytechnic University, Hebron, Palestine, Qabajeh Liana Khamis
Published: February 2022

Mobile Ad-hoc networks are getting progressively more popular. In such networks, nodes are continuously moving, hence, seeking an efficient route from a particular source to projected destination is a vital issue. Moreover, choosing a secure route is a tough area to deal with since adversaries may include themselves within these routes unless a strict secure procedure is implemented along with routing protocols. In managed-open environment, such as that formed by peers at a conference, using already established infrastructure as a starting point for assuring security is likely. Thus, this research proposes a novel paradigm of routing protocol named S-Octopus. Through tackling with area as sectors and utilizing restricted directional flooding, S-Octopus tries to achieve improved scalability. Moreover, S-Octopus seeks to increase robustness and alleviate single point of failure and compromise problem via picking up numerous sector certificate authorities. A qualitative comparison among S-Octopus and some other secure Ad-hoc routing models is presented in this paper.

Published: February 2022

This paper presents an Internet of Thing (IoT)-based instrumentation development using vibration sensor, force sensor, and Blynk app to obtain the reaction time, kick impact force, and flexibility index based on visual stimulants. Besides the Blynk app, vibration, and force sensors, other main components of the prototype are the Arduino NodeMCU microcontroller, and three LEDs (yellow, red, and green). The developed prototype was able to record the reaction time, kick impact force, and flexibility index. These outputs could be viewed not only on the Organic Light Emitting Diode (OLED) display but also on the smartphone via the Blynk app interface. To evaluate the performance of the developed prototype, four male Silat athletes weighing between 61kg to 80kg were recruited for this experiment. They were requested to undergo a Simple Reaction Time (SRT) task which requires them to perform three trials of the front kick. From the SRT findings, it can be deduced that 75% of the participants reacted faster towards green LED with the fastest reaction time recorded was 1485.2±126.7ms compared to yellow and red LEDs. In the future, the design of the hardware in terms of circuitry and hardware casing will be improved for a better prototype presentation. Secondly, a big sample size of subjects and different branches of combat sports will be recruited to assist in further analysis. Furthermore, the sound stimuli will be included in future studies. Lastly, further research should be conducted to assess the effect of colored stimuli on the reaction time of the athletes.

Published: February 2022

Distributed Generation (DG) is commonly used to reduce active power losses on a distribution network. The optimal location and size of DG will result in minimum active power losses and voltage profile improvement. This research proposes Novel Voltage Sensitivity Index (NVSI) and Stability Index (SI) methods to determine the optimal location and analytical expression to find optimal size and location of DG in Makassar distribution system, Feeder Kima, 76 buses to minimize active power losses and to improve voltage profile. Therefore, DG interconnection has a significant effect on improving the quality of the distribution network. The results show that the sensitivity method does not lead to the best placement DG in reducing active power losses. However, it is an analytical expression, which is very effective in determining optimal location and size of DG to reduce active power losses and to improve voltage profile in Makassar distribution system, Feeder Kima, 76 buses. The most optimal location for DG placement is on Bus 73 (Mega Sakti Pyramid), with a DG size of 0.8515MW. These combinations reduce 45.77% active power losses and increase 1.7336% voltage profile.

Published: February 2022

The implementation of an energy efficiency intervention in the students’ residence of the university campus may lead to a reduction in the energy consumed and electricity cost. The study focused on retrofitting a 1000 L, 12 kW boiler, with a 4.0 kW Air Source Heat Pump (ASHP) unit. A data acquisition system was built and deployed, to monitor the baseline performance of the electric boiler and the actual performance of the installed ASHP water heater (which was used to retrofit the electric boiler during the assessment period). The results show an annual electrical energy saving of 34805.94 kWh and load factor reduction of 0.124 due to the replacement of the electric boiler with the ASHP unit. The payback period of the ASHP system was 1.7 years, using the method of net present value of money. Wilcoxon rank sum test was employed to compare both the daily volume of water and energy consumed by the electric boiler and the ASHP water heater to test if their difference was of any significance. We concluded that, there exists a significant difference in the average daily energy consumed by the boiler and the ASHP water heater in both summer and winter season with the utilization of the Wilcoxon rank sum test. We could conclude that, a rollout of the ASHP units to retrofit the existing electric boiler in the students’ residence in the University campus is economically viable and calls for such an intervention is imperative.

Scleredema — Rare skin manifestation in diabetic
Authors: Nimbolkar Janardan , Thacker Hemant , Gandhi Bhavesh
Published: February 2022

Scleredema is a connective tissue disorder of unknown etiology.

A 44 years diabetic, obese female patient, admitted with edema feet, erythematous, indurated hyper pigmentation with ascending progression to trunk which rapidly transformed to painless dark pigmented blister and hard non-pitting edema of anterior abdominal wall. In a week time. She was managed with broad spectrum antibiotics, was aggressively diuresed along with albumin infusion. Her skin biopsy was done which revealed scleredema. She had poor LV function due to volume overload or cardiomyopathy. After initial improvement on 14 day, she suddenly developed fulminant septicemia. Within hours, she displayed multi organ dysfunction and the heart and kidney which were already delicately balanced, decompensated. There was intractable arrhythmias and severe LV dysfunction, renal failure and ischemic hepatitis following severe hypotension.

Scleredema in diabetic subjects, can be an ominous sign for producing fulminant multiorgan dysfunction and can present as cardiomyopathy, myocarditis, liver dysfunction etc., and these patients are more prone to infections or may be vice versa. Scleredema can be considered as a marker of fulminant illness in immunocompromised individuals. There is a need for treatment protocols or research into this a rather enigmatic but rare illness.

This work describes the patterns of changes in activity of gamma-glutamyltransferase (GGT) in tissues of various liver lobes (caudate, mastoid, right outer, left outer, left inner, and square) of gray giant rabbits at different phases of postnatal ontogenesis. The enzyme activity was determined by spectrophotometric method in the scientific laboratory of Chuvash State Agrarian University. It was revealed that rabbits are born with different enzyme activities in the studied liver lobes, and the intensity of age-related changes of GGT activity in the studied rabbits’ periods of life in the tissues of liver lobes is diverse, which is connected with change of vegetable feed composition and with unequal need for enzyme participation in metabolic processes in the body tissues during the studied early postnatal period. The most intense changes in enzyme activity with age of rabbits occur at colostrum-milk phase in the square lobe; as for the first phase of milk nutrition - in the right and left outer lobes; the third phase of milk nutrition - in the left inner and in the square lobes; in the second phase of transitional nutrition - in the left inner lobe. Stabilization of GGT activity does not happen by the age of two months.

It is possible to reduce the degree of systemic complications arising in response to spinal cord injury by providing timely medical care. Positive therapeutic effect of intrathecal administration of hyaluron gels is known for such injuries. In turn, these medications can be used as carriers of other medical substances. The aim of the research is to study hemodynamics in hind limbs in case of traumatic spinal cord injury using an anti-adhesion gel which contains Na-carboxymethyl cellulose. Rats’ spinal cord injury at the level of the thoracic section of the spine was simulated and a hyaluronic-containing anti-adhesion absorbable gel was injected into the injury area. Hemodynamics and temperature response of pelvic limb tissues were studied. Heart rate dynamics and general body temperature were assessed. The quantitative data were compared with the physiological norm. The animals were observed for 90 days. No heart rhythm disturbances were noted. During the experiment, hyperthermy of central genesis was recorded, which was characterized by an increase of the total body temperature to a maximum of 37.11 ± 0.6 ° C (p = 0.004) and local temperature - up to 34.48 ± 2.24 ° C (p = 0.002). The phenomena of vasodilatation of the arteries were observed, which were more pronounced after 60 days of the experiment. Further on, the visco-elastic properties of the vessels improved. Difficulties in venous outflow in the created conditions were not found. According to available literature data, when modeling a spinal cord injury without application of antiadhesion hyaluronic medications, vascular disorders are more explicit. Conclusion. The application of a hyaluronic anti-adhesion gel for traumatic spinal cord injury can reduce the intensity of emerging pathological conditions.

The submitted article presents materials on assessment of Simmental breed lines, used in farms of different breeding qualities, as well as on relationship between milk yield of cows for individual lactations and life-long productivity. It was found that milk yield correlation is the most explicit between the average parameters for three lactations and the average lifetime productivity in breeding herds (agricultural production co-operative “Combine” and experimental production farm “Tsentralnoye”). In the studied herds, the relationship between milk yield and milk fat content varies greatly in size and direction in many lines (from r = - 0.25 to + 0.17). The relationship between mothers and daughters is insignificantly expressed in terms of milk yield in all lines. The variability of milk yield of daughters is characterized by lower rates in comparison with mothers in three lines - Floriana 374, Brazil 141, Krepysh 50. Low “mother - daughter” correlation in milk yield and homogeneity of daughters in milk yield indicates a significant influence of daughters of prepotent bulls on milk yield. The highest heritability of milk yield was established in Zipper 085 line (h2 = 0.44 - 0.66), which reveals a large genotypic diversity of animals in these lines.

The aim of the research is to study the effect of “Phytocomplex S. coronata” supplement on clinical and biochemical status of calves, blood morphology and productivity of dairy cows. The content of ecdysteroids in the additive was determined by highly-efficient liquid chromatography. The experiments were organized in Kirov region. One control and three experimental groups of calves at the age of 1.5 months were selected. Each group included 10 heads. Phytocomplex S. coronata was mixed with water and given to calves for 30 days: group 1 - 10 g, group 2 - 20 g, group 3 - 30 g / calf. Phytocomplex S.coronata was given in the experiment on lactating cows once a day for 60 days: group 1 - 50 g, group 2 - 100 g and group 3 - 150 g / head. Animals in the control were kept on the farm ration without additives. Blood tests of calves (total protein, albumin, ALT, urea, total cholesterol, sublimate test, reserve alkalinity) and cows (erythrocytes, leukocytes, hemoglobin) were carried out at the beginning and at the end of the experiments. It was found that the concentration of ecdysteroids is 500 mg / kg in Phytocomplex S. coronata. The amount of total protein in the blood of calves from the experimental groups increased to 65.7 ± 4.2 - 68.0 ± 2.5 g / l (P <0.05), albumin to 31.5 ± 1.2 - 33.2 ± 1.2 g / l (P <0.05). By the end of the experiment, the average daily milk yield of cows in the experimental groups exceeded the result in the control by 3.7%, milk fat by 0.3%, protein by 0.6%. (P <0.05). By the end of the experiment, the number of erythrocytes and hemoglobin in the blood of cows of the experimental groups significantly (P <0.05) exceeded these parameters at the beginning of the experiment, while in the control there were no significant changes (P> 0.05).

Recently, many works devoted to the study of animal welfare have appeared in Russia. This topic has long been of great scientific interest in foreign countries. Problems related to the welfare of animals lead to a decrease of their productive longevity, an increase of morbidity, impaired reproductive abilities and quality deterioration of the obtained products. Particular attention should be paid to the study of animal welfare on agricultural farms and complexes where the most severe exploitation of animals takes place. Based on this, studies were carried out on the level of animal welfare on a farm of Penza region, engaged in pork production and processing. The object of the study was a crossbred rearing stock. Well-being was assessed based on the EC Welfare Quality assessment protocol for pigs algorithm. This algorithm was developed at Waginengen University and Research Center in the Netherlands. The essence of the methodology is to assign points to the criteria and principles of animal welfare. In the course of the research, an integral assessment of the level of animal welfare on the farm was carried out, a complex score was calculated and a “welfare category” was assigned. It was established that the animals on the farm are provided with a sufficient amount of balanced food and water, are kept in rooms with an appropriate microclimate, there is a place in the crates for rest and movement, there is also demonstration of species-typical behavior and social communication. The results obtained with the help of the EU Welfare Quality algorithm also identified vulnerable aspects in animal housing that affect the welfare.

The article considers the results of rapeseed drying, which was carried out by convective method on mine, mounted, bunker, as well as recirculation dryers designed for grain drying. Impulse IR drying allowed to intensify the process while preserving the seed quality. Combined method of IR-drying is more effective, in particular, in a fluidized layer at low intensity of the IR-flow, when irradiation is combined with air heating, including oscillation, alternating the supply of heated and outside air in case of continuous IR-irradiation. The duration of IR-drying is calculated for both constant and oscillating heat supplies. The modes of combined IR-drying are experimentally defined. The object of the study was the technological process of drying of rape seeds in a fluidized layer with intensive mixing of the material. The total power of the IR flow and convectively heated heat-transfer agent did not exceed the limiting seed temperature. The calculation of the combined drying duration was carried out similarly to convective drying, and the effect of IR radiation was estimated by the equivalent temperature of the drying agent. A range of experiments was carried out with the IR flow impact on damped rapeseeds when blowing with external and heated air with formation of a fluidized layer. The thickness of the rapeseed layer was changed from 0.05 m to 0.1 m, the speed of the drying agent was 0.65 m / s. The power of the IR lamp varied from 400 W / m2 to 900 W / m2. Seed germination was determined before and after the experiments. The combined IR-drying duration of rape seeds in a fluidized layer was calculated. Well-known calculation expressions for convective drying were used, which included the heat transfer coefficient, moisture removal, specific heat of moisture evaporation, the temperature difference between the drying agent and the mean of the material, as well as the proportion of heat that was used for moisture evaporation, but with an equivalent temperature of the drying agent. The duration of IR drying was calculated in the same way as for convective drying, taking into account the equivalent temperature of the drying agent. It was established that a rational mode of rapeseed IR-drying requires the power of the IR-flow of 0.65 kW / m2, with a variable 5-minute blowing of a rapeseed layer with a height of 0.1 m heated by 25 ° C and outside air with a temperature of 15 ... 20 ° C.
