Abstract A study of antifungal properties of violacein-forming strain Janthinobacterium sp. B-3515 as well as its secondary metabolite, violacein, against Alternaria brassicicola F-1864 is presented. Regardless of the presence of bacteria, mycelium growth in the first two days proceeded at the same rate. The effect of the bacterial strain was manifested after the third day of incubation. In general, during co-culture, the bacterial strain statistically significantly reduced the average growth of the mycelium of the mould fungus by 10%. The average growth of A. brassicicola F-1864 was decreased in the presence of an aqueous solution of violacein in the nutrient medium (1%, 3%, and 5%). The pigment in 5% concentration had the greatest effect, as the difference between the average growth of the control group and the experimental group was 18%. The mycostatic activity of bacteria of genus Janthinobacterium and violacein against mould fungus Alternaria brassicicola F-1864 was shown for the first time.

Studies were carried out on cattle gobies in one of the farms of the Ivanovo region from May to October. We selected two groups of agelmint animals of 15 heads 11.5–12 months of age. Both groups of animals were grazed on lowland (flood) pastures. The first (control) group of gobies did not receive anthelmintics during the pasture season. Animals of the second (experimental) group were dewormed three times with fenbendazole at a dose of 20 mg / kg in the DV, individually, twice. In the gobies of the control group, for the first time, helminth eggs in the faeces were found in July. During this period, eggs were found to be strangulated, trichocephalic, and moniesia. In August and September, the infection of animals with helminths gradually increased. In October, all the livestock of calves was invaded by nematodes, cestodes, and trematodes. In the animals of the experimental group, by the end of July, moderate invasion by strongylats, trichocephalus and moniesia was registered, so they were subjected to double deworming with fenbendazole. In August, they were free from helminths, and in September, fasciola eggs, nematodes from the strongylata and trichocephalata and moniesia suborders were found in their feces. In September, the animals again dewormed with fenbendazole twice. In October, only trichocephalus eggs were found in the calves' feces. In calves that underwent chemoprophylaxis during the pasture season, average daily gains increased by 53.9 g. (9.47%). In order to reduce losses from helminth infections, young cattle should be dewormed three times while grazing them on lowland, flowing pastures. The first time – in July, the second time – in late August, the third – in September.

Abstract Background This study was done to observe the incidence of Osteo-line on the femur neck and to explore the clinical application of Osteo-line in osteotomy. Methods Eighty-nine adult femur specimens were selected to observe the incidence of Osteo-line on the femur neck. From August 2015 to January 2019, a total of 278 patients who completed unilateral hip arthroplasty at the Third Hospital of Hebei Medical University were retrospectively included. Patients who accepted osteotomy via Osteo-line on the femur neck were defined as the experimental group (n = 139), and patients who accepted osteotomy via traditional method (The femoral distance 1.5 cm above the trochanter was retained for osteotomy by visual inspection.) were defined as the control group (n = 139). According to the postoperative pelvic X-ray, Photoshop was used to evaluate the leg length discrepancy (LLD) by the CFR-T-LT method. Results Among the 89 specimens, the incidence of anterior Osteo-line was 75.28%, and the incidence of posterior Osteo-line was 100%. According to the clinical application results, the incidence of anterior Osteo-line on the femur neck was 80%, and the incidence of posterior Osteo-line was 100%. The Osteo-line was clearer than those on the femoral specimens. Twenty-six cases had LLD greater than 1 cm (9.29%), including 2 cases in the experimental group and 24 cases in the control group. The average postoperative LLD in the experimental group (0.19 ± 0.38 mm) was significantly shorter than in the control group (0.54 ± 0.51 mm)(P = 0.005). Conclusion The incidence of Osteo-line on the femur neck was high, and patients who accepted osteotomy via Osteo-line on the femur neck can achieve shorter postoperative LLD than the control group.

Objectives: In this paper, the effects of tobacco on aerobic exercise ability and physical fitness recovery of college students were studied. Methods: University group sports intervention form: traditional characteristic project (basketball) + Taiji soft ball (R&D intervention project). Exercise time: 3 times/week; Activity duration: 30min; Activity intensity: the heart rate is controlled at 120-140 beats/min. All the college students in the experimental group are students who have never smoked, and the college students in the control group are students who have smoked for more than two years. The other conditions are the same. Results: The exercise time and endurance of experimental groups I and II were significantly lower than those of the control group, and the cardiopulmonary function was significantly lower than that of the control group. The indexes of experimental group II changed significantly compared with experimental group I, and the difference was statistically significant. Conclusion: Cigarette smoke can significantly reduce the aerobic exercise ability and anti fatigue ability. The longer the smoking time, the more serious the adverse effects. Therefore, tobacco smoke and nicotine will damage college students’ aerobic exercise ability and have a negative impact on the recovery of physical fitness after exercise.

The aim of the study is to increase the productive qualities of broiler chickens by including ultrafine silicon oxide into main diet. During the experiment, the biological effect of ultrafine silicon oxide on broiler chickens was estab-lished. Use of ultrafine SiO2 particles for poultry feeding contributed to an increase in the number of red blood cells and content of total protein and albumins. By the end of the experiment, the number of red blood cells in birds in-creased by 17.43% (P≤0.001) – in the blood of birds of the first experimental group, 16.51% (P≤0.01) – the second one, 20.80% (P≤0.001) – the third experimental and 21.71% (P≤0.001) – the fourth experimental group, compared with the indicator of the control group. The amount of total protein in blood serum of chickens of the first and the second experimental groups increased by 1.36-1.39 %, in the third and fourth ones there was a significant (P≤0.05) increase by 5.45 and 3.05%, respectively. The blood glucose content of chickens in the experimental groups is higher by 8.04-23.65% compared to this indicator with ones in the control group. During the experiment feed con-sumption per 1 kg gain of live weight decreased: in the first experimental group by 3.00 % in the second by – 0.50 %, the third – 6.00 % the fourth– by 4.50 %, compared to this with the control group. The chicken’s vibrancy of the first the experimental group was higher by 4.77 %, the second – by 6.20 %, the third – by 19.25 % and the fourth– by 11.59% than in the control one. Consequently, when converting the feed energy into the body energy of a broiler chicken, the energy conversion coefficient of the experimental group of poultry is higher than that of the control one by 7.16-21.76 %. Thus, the most optimal dose for further research was determined.

The paper describes the process and outcomes of an action research project with the aim of determining whether focusing classroom input on voiced and unvoiced consonant sounds has a positive effect on their production. Statistics were derived from English-speaking respondents listening to native Arabic speaking participants from an experimental group, who had received input on the difference between these sounds, and practiced their production, as well as to speakers from a control group who had received neither input nor practice. The rates of intelligibility were compared, with the conclusion being that the provision of limited input on this pronunciation issue does not, generally speaking, result in the ability to produce the sounds with greater clarity.
