Rumen-fistulated cattle were fed fresh alfalfa herbage daily during two growing seasons. Samples of rumen fluid were collected daily prior to feeding and the frothiness of the rumen fluid was assessed. Concentrations of soluble protein nitrogen in the rumen fluid were higher in animals that subsequently bloated than in those that did not (P < 0.01). There was no relation between soluble protein nitrogen and the occurrence of foam in the rumen prior to feeding. The concentrations of Na and K in the rumen fluid were negatively correlated. Bloat was associated with a low concentration of Na and a high concentration of K (P < 0.01). Concentrations of Ca and Mg were lower than those of the two monovalent ions but were also positively associated with bloat (P < 0.01). The high concentration of chlorophyll associated with a predisposition to bloat may be the result of a colloidal aggregation of chloroplast particles stabilized by cations.

Chlorophyll levels in rumen contents from the dorsal and ventral sac were examined before alfalfa ingestion to determine the relationship of chloroplast particles to the onset of pasture bloat in cattle. Chlorophyll concentrations were significantly higher in cattle that subsequently bloated than in those that did not. The higher levels were observed in both the liquid and solid phases of rumen contents from cattle predisposed to bloat but the liquid phase showed a greater increase. Chlorophyll levels were uniformly distributed in the rumen with little or no difference between samples obtained from the ventral and dorsal sacs. In agreement with previous results, animals predisposed to bloat showed higher rates of gas production and greater buoyancy of particulate matter in prefeeding rumen fluid. The results suggest that chloroplast particles in the rumen have a slower rate of clearance in bloating animals than in nonbloating ones. Key words: Bloat, alfalfa, cattle, rumen, chlorophyll, chloroplast particles

Rumen-fistulated cattle were fed fresh alfalfa herbage daily during three growing seasons. Two hours after feeding the incidence of bloat and of ruminal frothiness was recorded and samples of feed and rumen fluid were collected for analyses of chlorophyll and soluble protein. These constituents were examined in relation to the bloat-causing potential of the alfalfa and in relation to the occurrence of froth in rumen contents. Chlorophyll in rumen fluid was higher on days when the alfalfa caused bloat, compared to days when bloat did not occur (P < 0.01). Chlorophyll was also higher in frothy rumen fluid than in normal rumen fluid (P < 0.01). Soluble protein concentrations in rumen fluid were adequate to stabilize foams in vitro but did not show any daily changes related to the frothiness of rumen contents. The soluble proteins could be involved in froth formation but another factor, perhaps a component of the chloroplast membranes, appears to be responsible for the immediate onset of frothiness. Key words: Chlorophyll, protein, cattle, alfalfa, bloat, rumen

Dynamic and thermodynamic characteristics of gasoline vapor adsorption at 0.3 mol/mol on different activated carbons (ACs) were investigated. The adsorption capacities of AC1 and AC3 were 0.295 g/g and 0.189 g/g at 20 oC, and 0.284 g/g and 0.165 g/g at 30 °C, respectively. Bed temperature rise was up to 50°C to 60°C in the adsorption of gasoline vapor at 0.3 mol/mol.The heat effect formula for high concentration vapor adsorption was deduced to evaluate the relationship of the adsorption capacity of the activated carbons, the mole fraction of the inlet gasoline vapor, the recovery efficiency of the gasoline vapor with the temperature rise.

Abstract. The aim of this work is to investigate the relationship between indicators of cicatricial digestion and linearity of cows. Methods. The research was carried out in the breeding enterprises of the Sverdlovsk region on the livestock of Ural-type cows. Cicatricial fluid was collected with an oropharyngeal rubber probe, and a wooden yaw was also used. Cicatricial content was assessed at the Chelyabinsk Interregional Veterinary Laboratory. The pH value was determined by the electrometric method, VFA – in the Markgam apparatus, ammonia – by the microdiffusion method. Ciliates – in Goryaev’s chamber and under a microscope, bacteria – under a microscope with the addition of sodium chloride solution. Statistical data processing was carried out in the Microsoft Office Excel 2010 program. Results. In terms of the number of ciliates and bacteria in the rumen fluid, the Montwick Chieftain cows, characterized by high productive qualities, had an advantage. In terms of pH and VFA, the Vis Back Ideal line was the best. There were no significant differences between the groups in terms of the amount of ammonia in the rumen. The best animals from the point of view of influence on cicatricial metabolism were the animals of the Vis Back Ideal and Montwick Chieftain lineage. Scientific novelty. Studies have shown that linearity is associated with cicatricial digestion in cows. The relationship of bull lines with indicators of cicatricial metabolism of cows has been determined for the first time. The food in the rumen is digested due to the action of bacteria, ciliates, and fungi. An environment has been created in the rumen for the active development of microflora. Bacteria are able to synthesize amino acids and vitamins. The proventriculus can contain up to 50 species of ciliates.

The aim of this study was to improve understanding of (1) the effect of genotypic and environmental factors on pre-anthesis development and leaf appearance traits of barley and wheat; (2) the relationship of these factors with grain yield, and (3) the differences between these two crops across different environments/sowing dates. Therefore, trials with six two-row winter barley and six winter wheat cultivars were carried out in two successive growing seasons on four sowing dates. Our study showed that the observed traits varied between species, cultivars and sowing dates. In both growing seasons, biomass at anthesis and grain yield declined almost linearly by delaying the sowing date. There was no clear advantage in grain yield of wheat over barley under conditions of later sowing dates. Generally, barley produced more leaf and had shorter phyllochron than wheat. Both wheat and barley showed a similar relationship between grain yield and different pre-anthesis traits.

The incidence of common blight, halo blight and brown spot on French beans was surveyed in the Bairnsdale-Lindenow and Orbost areas in East Gippsland during the 1975-76 and 1976-77 growing seasons. Common blight and halo blight were severe only during late January to March, and occurred largely on mature crops. Common blight was the more severe disease in the Orbost area whereas halo blight was more severe in the Bairnsdale-Lindenow area. Brown spot occurred throughout the season on crops of all ages in both areas but was more severe in the Bairnsdale-Lindenow area. The relationship of weather to the incidence of bacterial blights in the two areas is discussed. It is inferred that losses due to common blight and halo blight could be considerably minimized by timing the planting of crops to harvest them by mid-February.

Embroidery is the craft of decorating fabric or other materials using a needle to apply thread or yarn. Embroidery may also incorporate other materials such as pearls, beads, quills, and sequins. In modern days, embroidery is usually seen on caps, hats, coats, blankets, dress shirts, denim, dresses, stockings, and golf shirts. Embroidery is available with a wide variety of thread or yarn color. Embroidery can be classified according to what degree the design takes into account the nature of the base material and by the relationship of stitch placement to the fabric. The main categories are free or surface embroidery, counted embroidery, and needlepoint or canvas work. Embroidery was an important art in the Medieval Islamic world and in Azerbaijan, too. The article dedicated to the medieval embroidery of Azerbaijan. It was given some information about this part of weaving craft. Key words: weaving, embroidery, textile, archaeology, ethnography
