Australian Wheat

A simple and accurate test for determining the granularity of wheat wholemeal is described. Ten grams of wheat are ground, sieved for five minutes and the amount passing through the sieve is expressed as a percentage of the original sample and recorded as the particle size index. Particle size index is shown to be a varietal character that divides Australian varieties into two distinct groups. As all typical hard varieties fall into one of these groups and all typical soft varieties into the other group, particle size index is suggested as the most satisfactory criterion for designating these categories. Variations in protein level and moisture content do influence the particle size index, without in any way invalidating the test. The effect of changes in these environmental factors, on particle size index, varies from variety to variety both in degree and direction.

Pen studies were conducted with cattle in which the digestibility, rate of fermentation, site of digestion and grain loss in faeces were measured in diets comprising 4.8 kg of one or other of four cereal grains together with 2.4 kg of pasture hay. The cereals were Avon oats, Swan oats, Olympic wheat and Emblem wheat with natural weights of 48.3, 60.5, 81.3 and 78.8 kg hl-1 and particle size index 24, 35, 31 and 14, respectively. The apparent in vivo digestibility of Avon and Swan oats of 71.9 and 74.6 did not differ significantly (P > 0.05). However, there was significantly less grain cracked during initial mastication (12.5 vs. 19.2 per cent and a lower percentage of grain voided in faeces (4.3 vs. 9.3) for Avon compared with Swan oats (P < 0.05). The in vivo digestibility of wheat grain was significantly higher for Olympic than for Emblem (77.5 vs. 72.6 per cent) ;these performances were accompanied by lower percentages of grain cracked during initial mastication (17.0 vs. 22.3) and less whole grain DM voided in faeces (14.6 vs. 18.4 per cent) for Olympic compared with Emblem (P < 0.05). The major difference in the digestion of oat and wheat varieties was that rumination accounted for a high proportion of the breakdown of oat grain whereas the wheat varieties were digested by rumen fermentation with only a small proportion of grains broken down by rumination. The breakdown of whole grain in rumination was important for all rations. For the light oats, heavy oats, soft wheat and hard wheat, rumination accounted for 66 per cent, 44 per cent, 27 per cent and 17 per cent of the total breakdown respectively.

Aim. The aim of this work is to study the nucleotide sequences variability of two genes encoding wheat dehydrins. One of them belong to K-2 group, the other refers to K-3 type (respectively, TaDHN18 and TaDHN19.3 according to the classification of Wang et al.). These loci sre interesting due to their's genes participation in protection of plants from the various adverse abioti ecffects. Methods. Polymorphism of two genes encoding dehydrins was investigated using 6 wheat varieties as examples, among which were spring and winter varieties with different cold resistance, using PCR-based cloning, sequencing, and data processing softwares. Results. An analysis of the obtained nucleotide and hypothetical protein sequences alignment showed that the locus under study in the genomes of different wheat varieties, both spring and winter, is characterized by a high identity degree. Conclusions. The high conservatism of two loci encoding K-2 and K-3 dehydrins was demonstrated. Keywords: wheat, dehydrins, polymorphism.

Size Index

The maximum desirable grain hardness is related to protein level and to the end product. Three methods of measuring the hardness of wheat are considered, and their dependence on other grain characteristics is shown to vary according to cultivar. Particle size index provides the best estimate of starch damage, and pearling resistance the best discrimination between cultivars. The pattern of site and seasonal effects shown by one hardness test is different from that shown by another.

Multichannel ABR recordings for 30 otoneurologic patients were reviewed independently by three audiologists to assess interjudge consistency in determining absolute latencies and overall interpretation of ABR results. Four months later, the tracings were reviewed a second time to evaluate intrajudge consistency in interpretation of ABR waveforms. Interjudge agreement in marking latencies for waves I, III, and V within 0.2 ms was on the order of 90% or better. Intrajudge consistency was slightly higher. Only rarely did inter- or intrajudge differences in latency measurements exceed 0.3 ms. Agreement in overall interpretation of ABR results as "normal" or "abnormal" was unanimous for 90% of the patients. Across pairs of judges, the agreement for "normal" and "abnormal" classification of the ABR tracings was 97%. Intrajudge consistency for "normal" and "abnormal" categorization of the ABR results was 100% for one judge, 97% for the other two judges.

Broad Understanding

The paper considers a point of view, based on the conception of the broad understanding of taxons. According to this point of view, rhyncholites of the subgenus Dentatobeccus and Microbeccus are accepted to be synonymous with the genus Rhynchoteuthis, and subgenus Romanovichella is considered to be synonymous with the genus Palaeoteuthis. The criteria, exercising influence on the different approaches to the classification of rhyncholites, have been analyzed (such as age and individual variability, sexual dimorphism, pathological and teratological features, degree of disintegration of material), underestimation of which can lead to inaccuracy. Divestment of the subgenuses Dentatobeccus, Microbeccus and Romanovichella, possessing very bright morphological characteristics, to have an independent status and denomination to their synonyms, has been noted to be unjustified. An artificial system (any suggested variant) with all its minuses is a single probable system for rhyncholites. The main criteria, minimizing its negative sides and proving the separation of the new taxon, is an available mass-scale material. The narrow understanding of the genus, used in sensible limits, has been underlined to simplify the problem of the passing the view about the genus to the other investigators and recognition of rhyncholites for the practical tasks.

Fenugreek Seed

Experiment to identify ambient grinding conditions and energy consumed was conducted for fenugreek. Fenugreek seeds at three moisture content (5.1%, 11.5% and 17.3%, d.b.) were ground using a micro pulverizer hammer mill with different grinding screen openings (0.5, 1.0 and 1.5 mm) and feed rate (8, 16 and 24 kg h-1) at 3000 rpm. Physical properties of fenugreek seeds were also determined. Specific energy consumptions were found to decrease from 204.67 to 23.09 kJ kg-1 for increasing levels of feed rate and grinder screen openings. On the other hand specific energy consumption increased with increasing moisture content. The highest specific energy consumption was recorded for 17.3% moisture content and 8 kg h-1 feed rate with 0.5 mm screen opening. Average particle size decreased from 1.06 to 0.39 mm with increase of moisture content and grinder screen opening. It has been observed that the average particle size was minimum at 0.5 mm screen opening and 8 kg h-1 feed rate at lower moisture content. Bond’s work index and Kick’s constant were found to increase from 8.97 to 950.92 kWh kg-1 and 0.932 to 78.851 kWh kg-1 with the increase of moisture content, feed rate and grinder screen opening, respectively. Size reduction ratio and grinding effectiveness of fenugreek seed were found to decrease from 4.11 to 1.61 and 0.0118 to 0.0018 with the increase of moisture content, feed rate and grinder screen opening, respectively. The loose and compact bulk densities varied from 219.2 to 719.4 kg m-3 and 137.3 to 736.2 kg m-3, respectively.

Functional autonomic disorders occupy a significant part in the practice of neurologists and professionals of other specialties as well. However, there is no generally accepted classification of such disorders. In this paper the authors tried to show that functional autonomic pathology corresponds to the concept of somatoform disorders combining syndromes manifested by visceral, borderline psychopathological, neurological symptoms that do not have an organic basis. The relevance of the problem of somatoform disorders is that on the one hand many health professionals are not familiar enough with manifestations of borderline neuropsychiatric disorders, often forming functional autonomic disorders, and on the other hand they overestimate somatoform symptoms that are similar to somatic diseases.
