Published: June 2023

The sea height level along Libyan coasts is considered one of the environmental pressures that lives in soil vegetation characteristics. Therefore, two experiments were conducted (laboratory - pots) to find out the effect of irrigation with seawater at the concentration (10%, 20%, 40%, 60%) on germination of seeds and seedlings of Bauhinia variegate trees with an age of 6 months, and treated using pre-soaking in gibberellin acid ( GA3) 500ppm for 24 hours. The results showed that the exposure of seeds and seedlings of B.variegate trees to salinity led in two experiments to a significant decrease in percentage germination, an increase in means germination time, moreover, a decreased seedlings lengths, number of leaves/plant, shoot and root lengths, fresh and dry weight of seedlings compared with a control. The results also showed that the seeds and seedlings of B.variegate trees were able to germinate in different concentrations of seawater, except for 60% concentration which caused in death of seeds and seedlings, while pre-soaking treatment of seeds with gibberellin acid was not successful to overcome the salt stress, although slightly improved some studied traits. The results concluded that the possible seeds and seedlings agriculture of B.variegate trees in coastal locations in which seawater concentration did not exceed 40%, existed to be used in reforestation of degraded lands.

Authors: Oleiwi Maryam Qays , Sulaiman Mohd Khairul Azhar Mat , Mohamed Mohd Farid
Published: June 2023

Recently, passive cooling strategies have gained more attention as an alternate method of cooling and ventilating indoor areas as part of a push toward more sustainable architecture. Passive cooling relies on free and sustainable energy sources such as the sun and wind to provide the necessary cooling, ventilation, and lighting for buildings to provide a comfortable indoor environment, therefore, the electrical energy that required for mechanical cooling can be reduced. The studies showed that these solutions have the potential to save good amount of building's cooling energy annually -about 23.6%-, depending on building type, construction materials, windows’ area and other specifications. In spite of that, the specifications need to be implemented and well-designed in an integrated system. This paper aims to review and discuss the possible passive cooling strategies that can be implemented in the hot-humid climate as a step towards decreasing energy consumption. A review of the literature has been done by searching for the appropriate keywords. It was found that many studies have highlighted the significance of using several types of passive cooling strategies for enhancing thermal comfort inside the buildings in the hot-humid climate, while some other strategies are not recommended. Protecting the buildings from direct solar radiation and applying natural ventilation to the buildings are the most effective passive cooling strategies that can be used in the hot-humid climate. The study recommended to review the appropriateness of several types of passive cooling strategies in different types of climates to highlight the most appropriate passive cooling strategies for each type of climate.
Keywords: Passive cooling, Natural ventilation, Green building, Thermal comfort, Building sustainability.

The paper presents the incorporating method of FeIIICl-tetraphenylporphyrin (FeClTPP) into the poly-N-vinylpyrrolidone (PVP) polymeric matrix. The resulting FeClTPP-PVP complex was diluted to final concentrations of 10, 20, 40, 60, 80 and 100 mmol and deposited on the inner surfaces of glass vessels. These vessels were used to simulate the surfaces of objects of veterinary and sanitary control that require periodic disinfection. The antibacterial activity of indicated concentrations of FeClTPP-PVP against antibiotic-resistant gram-negative and gram-positive microorganisms – Escherichia coli (strain 1257) and Staphylococcus aureus (strain 209-P) was demonstrated. As these microorganisms are also representatives of the most frequently encountered contaminants, we have studied the prepared bacterial suspensions from daily cultures of E. coli and S. aureus in dilutions from 108 to 104 CFU/mL. After that, the artificial contamination of the inner surfaces of the test objects was carried out. Antibacterial activity was determined by the degree of inhibition and was recorded visually and spectrophotometrically (OD600 nm ). The inhibitory effect on the growth of E. coli and S. aureus was directly proportional to the concentration of FeClTPP-PVP and inversely proportional to the degree of microorganism’s dilution. The greatest effect (about 87% reduction in bacterial growth) was achieved by the influence of FeClTPP-PVP maximum concentration.

The article presents the results of veterinary and sanitary examination of meat of broiler chickens 42 days old when using a four-component sorbent (shungite, zeolite, lignin and glucan) in feed with experimental mixed mycotoxicosis (T-2 toxin, aflatoxin B1, DON, zearalenone, fumonisin B1). It was found that in the study of chicken carcasses of group 4 (daily intake of mycotoxins without the use of sorbent), there were small deviations from the norm, leading to a reduction in shelf life, in the form of a decrease in muscle consistency, an increase in meat moisture and the appearance of a slightly sour smell. Microscopy of smear prints taken from different muscle layers of broilers of this group showed the presence of single coccoid and rod-shaped microorganisms in the deep and surface layers of muscle tissue. At the same time, the pH of meat in the group of chickens treated with mycotoxins was 6.5, while in the other groups it ranged from 6.0 to 6.1. The reaction to peroxidase of poultry meat samples of chickens treated with mycotoxins was negative, the reaction with copper sulfate was positive; when setting the formative reaction, the extract was cloudy and contained fine flakes. The introduction of the sorbent into the mycotoxin-contaminated diet helped to improve the indicators of veterinary and sanitary analysis of chicken meat to the level of control.

Residual amounts of antibacterial drugs found in fish products and aquaculture can cause significant harm to the consumer, causing allergies and various diseases, so there is a need to develop and validate modern methods that allow not only qualitatively, but quantitatively determine the residual amounts of various antibiotics and antibacterial substances. During the validation of the Randox® Biochip bioluminescent method, we obtained experimental data that showed the promise of this method for detecting residual amounts of antimicrobial substances of various groups in fish and aquatic products. The use of Randox technology significantly reduces the time of analysis of the samples under study, allowing you to simultaneously analyze about 50 samples within one working day. Using the immunomicrochip method, the optimal parameters for sample preparation were determined. The use of the Antimicrobial Array I Ultra panel for the determination of residual amounts of sulfonamides showed the possibility of its use for the simultaneous determination of 20 drugs and sulfonamides. The use of the Antimicrobial Array II Plus panel made it possible to determine the residual amounts of 35 antibacterial drugs simultaneously from the groups of tetracyclines, thiamphenicols, quinolones, streptomycin, etc. The use of the Antimicrobial Array III panel made it possible to identify residual amounts of several groups of antibacterial drugs simultaneously in one shrimp sample.

The article presents the technique of paracentesis of the anterior chamber of the eye with simultaneous intra-chamber administration of 0,5% pilocarpine solution, to identify the dynamics of intraocular pressure reduction, as well as to determine the effectiveness of this procedure both immediately after its execution and in the long term; based on the analysis of the data obtained, to determine complications. The study included 37 animals (39 eyes): 24 dogs and 13 cats with glaucoma, which, according to the anamnesis, developed no more than 10 days. without any prior hypotensive treatment. All animals underwent paracentesis without the use of general anesthesia or sedation. The procedure was performed under 6x magnification using frontal illumination, with a 27G needle for 9 hours for the right eye and for 3 hours for the left eye. The puncture was carried out on the periphery of the cornea at a distance of 1 mm from the limb. The volume of aspirated intraocular fluid was no more than 2 drops. Then a 0,5 % solution of pilocarpine was injected into the anterior chamber through the opening of the paracentesis. The volume of the injected solution did not exceed 0,3 ml. After paracentesis and pilocarpine administration, dexamethasone solution was subconjunctively instilled in combination with gentamicin and novocaine. Then hypotensive therapy was prescribed from a combination of eye drops. The study shows that the method with simultaneous intra-chamber injection of 0,5 % pilocarpine solution is effective in dogs and cats without any pronounced side effects. These results allow us to suggest anterior chamber paracentesis as a procedure for emergency reduction of intraocular pressure, especially in acute attacks of glaucoma in dogs and cats.

The article presents the morphological and functional characteristics of the powerful knee extensor in the noble spotted deer. The research was carried out at the Department of Anatomy and Histology of Animals named after Professor A. F. Klimov of the Moscow State Academy of Veterinary Medicine and Biotechnology – MBA named after K. I. Scriabin. The objects of research were mature noble spotted deer (n=5). Topical features of anatomical formations on the pelvic (nameless) and femoral bones were revealed – the site of the lateral head of the quadriceps femoris muscle on the large trochanter of the femur; «the lateral site for fixing the rectus quadriceps femoris muscle », «the crest of the rectus femoris muscle» on the ilium. When studying the architectonics of the quadriceps femoral muscle, the points of attachment of its heads, the orientation of the bundles of its muscle fibers, it can be argued that the muscle, being multi–articular, is able to perform extension and abduction of the knee joint, and its straight head – flexion and supination of the hip joint. Equipped with lateral and medial tendons, the intermediate head, with a significant degree of probability, implements the positional stability of the kneecap on the femoral block. When analyzing the phases of the static-locomotor act, it was found that when the fulcrum changes, the function of the muscle changes, which may be due to the organ and biomechanical specificity of topographically coupled joints. The revealed anatomical features of the quadriceps femoral muscle are the reference in assessing the structural and functional state of the knee joint in the noble spotted deer and diagnosing its pathologies associated with impaired functioning of its ligamentous-muscular system.

The rabbits of the experimental group were grown using the drug «Nitamin» (the animals received «Nitamin» with water for drinking, from 60 days of age for four days and from 74 days of age for four days at the rate of 1 ml / 1 liter of water), the control group did not receive the drug. The results of the studies showed that the meat of rabbits treated with «Nitamin» with dri nking water, in terms of the total number of essential and non-essential amino acids, prevailed by 2,3 and 0,7 %, respectively, in comparison with the meat of rabbits of the control group. The mass fraction of protein in the meat of experimental rabbits significantly increased by 2,5 %, while the mass fraction of fat decreased by 1,8 % compared with the samples of the control group. The amount of iron in the meat of rabbits of the experimental group significantly increased by 83,33 % compared to the control group. The obtained data on the use of the drug «Nitamin » in rabbit breeding indicate an increase in the nutritional value of the resulting product while maintaining the dietary properties of rabbit meat.

However, the experience of her work has shown that modern technology has violated to a certain extent the relationship of the body of pigs with the environment with traditional conditions of keeping and feeding. But recently, the latest technical developments in the provision of methods for keeping pigs of different technological groups, methods and means of ventilation of premises, which have a significant impact on the level of metabolic processes and productivity of animals, have been rapidly introduced in pig breeding. This is especially true for such a vulnerable technological group as weaned piglets, during the growing period of which there are a number of critical life threats. Therefore, the only effective way is to optimize the technological parts of keeping pigs under the conditions of industrial pork production technology. The two-phase technology is characterized by the fact that, after weaning from sows, piglets are grown in nests, in the same pens where they were born, up to 90–120 days of age. Until they have a mass of 30–40 kg. And only then the animals are transferred to fattening. When growing according to the accepted technological scheme, young animals change only two production premises, therefore such a system of animal fattening is called two-phase. It reduces the stress on the animals, both due to the minimum movement of young animals, and because there is no struggle for leadership in newly formed groups of piglets. The criterion for evaluating various production technologies is the correspondence of physiological needs and genetic characteristics of farm animals to artificial environmental conditions. The article considers the influence of different terms of combining nests in the suckling period on individual productivity indicators, as well as on the ethological and hematological indicators of piglets. The expediency of combining three nests of piglets at the age of 21 days for subsequent rearing by one group has been proved. Although this method of combining nests predetermines a certain physiological stress in the animal organism, as evidenced by hematological parameters, however, it does not go beyond the normal range and no stress state is observed.

Specialists conducted local molecular and genetic studies of working individuals of honeybees in apiaries of the northern forest-steppe zone, covering the area of the Bashkir population of the Central Russian subspecies of honeybees, during which some reserves of Apis mellifera mellifera were identified. However, there are no detailed studies on the dynamics of the morphotypic and phenotypic structure and taxonomic assessment of drones in this territory. The material for this work is based on field studies conducted in the Askin, Baltachevsky, Burayevsky, Kaltasinsky, Karaidelsky, Krasnokamsky, Mishkinsky, Nurimanovsky, Tatyshlinsky and Yanaulsky districts of the northern forest-steppe zone of the Republic of Bashkortostan in 2017–2020. The object of research was the drones of honeybees. In total, more than 17 thousand copies of drones were collected and processed. The paper uses the method of F. Ruttner on the assessment of morphotypes. The studies were carried out on dry samples of bees. To determine the color of the hairs on the abdomen, the color scale of Prf. Goetze was used. As a result of the study of the phenotypes of honeybee drones, based on the analysis of morphotypes and color of the hairs on the abdomen, the distribution of three phenotypes was established (O-dark cuticle (brown – coffee), Is – a wide saddle – shaped stripe (black-smoky), 2R-two yellow rings on the cuticle (brown-coffee)) on apiaries of the northern forest-steppe zone, forming the Bashkir population of the Central Russian subspecies. It was revealed that all morphotypes were characterized by the presence of hair color corresponding to the standard of the Central Russian subspecies. The phenotypic diversity of bees living in the studied apiaries is determined, first of all, by the complex influence of the anthropogenic factor. At the same time, the timely implementation of breeding programs for the conservation and breeding of native bees, a certain geographical isolation of the northern forest-steppe zone, the isolation of apiaries will preserve the subpopulation structure of bees in this territory.

The article presents the results of a study on the effect of inhaled anesthetics on the state of the animal body during orthopedic surgical interventions to identify possible intra- and postoperative complications associated with anesthetic care. The studies were carried out on a group of clinically ill dogs with joint pathologies selected by the method of analogues without regard to gender and age. According to the results of the conducted studies, it was revealed that when using Isoflurane, unlike Sevoflurane, there is a significant decrease in blood pressure; an increase in the frequency of cardiac contractions; nephrotoxic and hepatotoxic effects, however, these indicators have a negligible effect on the general condition of the animal. The priority of choosing an anesthetic was not revealed in our study, since all the studied groups of animals underwent anesthesia well during surgical interventions.

One of the main tasks in dairy cattle breeding is the prevention and elimination of infertility and barrenness of the breeding stock. The causes and forms of infertility are very diverse, their ratio in different farms and regions of the country varies. An analysis of the results of obstetric and gynecological medical examinations of the breeding stock in the Altai Territory for 2019–2021 showed that with a decrease in the number of tested animals by 13,62 %, the number of detected patients remains at the same level and averages 14,48 %. When processing the data presented from all regions of the region over the past three years, natural and economic zones were identified, where diseases of the reproductive organs in animals reached more than 20 %. Thus, in the Kulunda zone, the number of animals with diseases of the reproductive organs increased from 24,02 to 29,04 %, in the Ob zone from 19,16 to 32,18 %. The problems of diseases of the reproductive organs in female cattle, according to our data and the analysis of official statistics, indicate the relevance and timely development of measures to prevent them and eliminate infertility in the Altai Territory.

Subarachnoid diverticula are extensions of the subarachnoid space filled with cerebrospinal fluid. They can cause spinal cord compression and neurological deficits of varying severity in dogs. At the same time, subarachnoid diverticula can be the only cause of neurological deficit, or they can occur with previous or concomitant pathologies. The first report of a subarachnoid diverticulum in a dog, then called a leptomeningeal cyst, was published in 1968 in E. D. Gage et al. As of November 2020, a total of 324 cases have been described in 39 English publications alone. But despite this, subarachnoid diverticula are still considered to be a fairly rare and little-studied pathology. This study is devoted to the main aspects of the diagnosis of subarachnoid diverticula in dogs and their surgical treatment (the use of decompression techniques). The article also discusses the role of magnetic resonance imaging in the final diagnosis and the importance of spinal cord decompression in the surgical treatment of subarachnoid diverticula in dogs.
