Treatment Comparisons

The growth of pastured calves, as affected by supplementary grain feeding, moderate and high prepasture planes of nutrition, and age on going to pasture (56, 112, or 168 days), was compared with growth of calves on a standard barn feeding regime. Seventy-two Holstein heifer calves were involved with treatment comparisons based on gains in body weight, withers height, heart girth, and barrel circumference.Over-all gains of pastured calves were not affected by either prepasture plane of nutrition or age to pasture and were similar to gains of barn-fed controls. Calves fed supplemental grain (crushed oats) showed no increase m growth rate. This was attributed to a lower intake of forage by the supplemented animals and the relatively high quality of the forage as indicated by chemical composition and digestibility.Seasonal growth patterns of pastured calves showed a depression during the initial period on pasture. However, this was overcome by greater gains than barn-fed controls during the later pasture periods.

Hatchery and culture technology of Humpback grouper has been developed. However,  sometimes it is still found constraint in sedd production and caused instability of production due to failure by many factors. Breeding program become necessary to provide seed with high quality and good genetic variation. Quantitative characteristic selection is one of breeding program to improve productivity in grouper aquaculture. The aim of this research was to produce good phenotyphic and genotypic quality of Humpback grouper candidate broodstock. Selection of Humpback grouper F1 and F3 was done based on quantitative characteristic (body length and weight) and genotyphic characteristic by using ramdom amplified polymorphism DNA (RAPD) method.  The results of conventional selection were found candidate broodstock of Humpback grouper F1 and F3 with body weight range from 170-210 g and 160-170 g consecutively.  Heterozygosity values of Humpback grouper analized by RAPD of F1 and F3 were 0.7940 and 0.7749 consecutively and it was not significantly different. This value emphasis that population of this F3 Humpback grouper was still good to grow for broodstock. Keywords: genetic variation, humpback grouper, F1, F3.

The Impact

The long lifecycle, also known as durability and the permanence / invariability in the quality of papers and cardbords for graphic art, are today the basic requirements, imposed by printed art in terms of high quality parameters. These two factors are a manifestation, depending on different internal chemical-composition properties of the paper consistency and external influences of the ambience. Longevity and permanence are perceived as a function of aging and are actually observed at a later point in time. It is important to clarify that they are terms with different contents where „durability” is perceived as the ability of the paper or cardboard to resist the impact of wear during use, and the „permanence” is the possibility of product to remain chemically and physically stable for a long period of time.

We determined seasonal changes in body mass and composition of arctic caribou (Rangifer tarandus granti) in relation to age and reproductive status. Chemical composition was determined for 37 caribou calves from the Central Arctic Herd ranging from 1 to 134 days of age and for 15 adult females collected from the same herd in October, May, and July. Body composition of 5 fetuses from the Central Arctic Herd, 13 calves from the Porcupine Herd, and 10 captive male reindeer (R. t. tarandus) was determined for comparison. Between October 1989 and May 1990, body fat and protein of adult females declined by maxima of 45 and 29%, respectively; an additional 32% of fat was lost between May and July. Mobilization of large amounts of fat and protein suggests winter undernutrition. Chemical composition and growth patterns of calves did not differ between the herds. The growth rate of Central Arctic Herd calves was high during the first 28 d post partum (402 g/d), but both growth rate and fatness declined between 4 and 6 weeks of age (to 306 and −18.3 g/d, respectively), perhaps in response to insect harassment. Birth masses of males and females did not differ, but by autumn, male calves were 9.1 kg heavier than females. Chemical components (water, fat, protein, ash) were highly correlated with body mass, ingesta-free body mass, and carcass mass. Percentages of fat and water were inversely related, but the intercept decreased with age. Marked seasonal hypertrophy of liver and kidneys was noted in caribou, suggesting the presence of mobilizable protein reserves. Seasonal changes in organ masses may also reflect variations in metabolic activity and nutrient intake.

The objectives of this research were to find out the optimum dose and frequency of feeding regime to ensure the maximum growth of carp-seeds, Cyprinus carpio, reared in the backyard pond with recirculation system. The experiment was carried out in 2x3 factorial experimental design and the experimental units were designed in randomized block.  Two factors were tested in this experiment; the first factor, dose of feeding, had three levels, 3%, 4% and 5% of the total body weight per day; and the second factor had 2 levels, 2 and 3 times per day.   Hence there were 6 treatments were applied, and each treatment was triplicated.   Each repetition represented group of fish with different weight.  There were 18 experimental units, and each experimental unit was composed of 8 tested fish, therefore there were 144 tested fish, which were weighed at the beginning of the experiment and then every week during the 6 weeks period of the experiment.  The weight data were converted into FCR, absolute, relative and daily growth rate, and were statistically analyzed using JMP statistic-program (SAS-institute).             The results showed the absolute growth of fish at dose of 3% was significantly lower than that of fish at the dose of 4% and 5%, which was not significantly different.   The relative and daily growth rate was not significantly affected by the different dose of feeding regime.  There was no significant difference in FCR, absolute, relative and daily growth rate between fish fed 2 and 3 times per day.  The best FCR, 1,46, was performed by fish fed 3% of the body weight per day, and this value was significantly different with that of the fish fed 4% or 5%.   The results of this experiment suggest that, carp reared in backyard pond with recirculation system should be fed twice a day, with a dose of 3% of the body weight each day.

This paper presents the results of the analysis of the quality of basalts, their heat treatment and studies of changes in the chemical composition of basalts, which leads to a change in the external color of partially processed basalt raw materials (hereinafter referred to as semi-finished product). The results of a study of purified basalt from slime, impurities and hydroxides, changes in the chemical composition of basalt rock are presented. The prospects of heat treatment of a semi-finished product and obtaining multi-colored products from mineral raw materials is shown. It was found that the optimal firing temperature of the semi-finished product, the possible options for changing the external color and the criterion points of the thermal effect at which the basalt semi-finished product changes the external shade. These statements are of great scientific and practical interest in the fact that during the heat treatment of a semifinished product, basalt easily overheats and gradually acquires a different color, which occurs to a liquids temperature and allows the future to plan to obtain high-quality multi-colored products from basalts, for example, products for design.

Paulownia is a fast-growing woody tree, native to the forests of China. It belongs to the family Scrophulariaceae and is mainly used as a source of wood for furniture and musical instruments. Due to its fast-growing nature and high-quality of wood, there has been growing interest in cultivation and research of Paulownia in Nepal. Growth comparison was performed by measuring shoot length in in vitro condition. Among two species of Paulownia - Paulownia tomentosa (Thunb.) Steud and Paulownia fortuneii (Seem.) Hemsl., the growth rate of P. tomentosa was found to be 0.355 cm/week while that of P. fortuneii was found to be 0.637 cm/week in in-vitro conditions in MS medium supplemented with 0.1 mg/l NAA and 1mg/l BAP. Optimization of rooting methods was also performed, in which, sand rooting was found to be easier and more effective than in-vitro rooting. Dipping the plantlets in 1 mg/l of NAA was found to produce longer and denser roots than lower or higher concentrations during sand rooting.

Concrete Elements

As part of a new harbor development, a new offshore breakwater will be constructed, for which the use of coastal protection plain precast concrete elements (AccropodesTM II) is required. The applicable exposure class is S1 (ACI 318). Over 4'000 elements have been produced. The owner required guarantees on the sulfate resistance of the elements before accepting them for usage in the project. For this, a revision of the documentation available was conducted, complemented by a thorough field investigation, measuring the coefficient of air-permeability kT (Swiss Standard SIA 262/1) of preselected elements (damaged during transportation) and elements representing the 28 weeks of production. The site NDTs confirmed a high quality of the majority of elements that were judged fit for the purpose. However, the NDTs confirmed the questionable quality of those cast during the initial period, requiring further evaluation before acceptance.The paper presents the results of: water aggressiveness, cement chemistry, strength quality control and air-permeability kT, and the criterion used to assess sulfate resistance of the elements.
