Modified Method

A modified typical meteorological year (TMY) method is proposed for generating TMY from practical measured weather data. A total of eleven weather indices and novel assigned weighting factors are applied in the processing of forming the TMY database. TMYs of 35 cities in China are generated based on the latest and accurate measured weather data (dry bulb temperature, relative humidity, wind velocity, atmospheric pressure, and daily global solar radiation) in the period of 1994–2010. The TMY data and typical solar radiation data are also investigated and analyzed in this paper, which are important in the utilizations of solar energy systems.

In TD-LTE (Time Division-Long Term Evolution) system, Resource Element Group (REG) is the unit of de-resource mapping for Physical Downlink Control Channel (PDCCH), due to the reference signal should be considered, which lead to the large calculation. To solve this problem, a modified method is proposed in this paper to reduce the cycles of de-resource mapping. Calculation and simulation reveal that this scheme can reduce the calculation significantly. At the same time, the feasibility and effectiveness of this modified method have been verified.

The article discusses a method for diagnosing nitrogen nutrition of spring barley (Hordeum vulgare L.) in different phases of the growing season using a photometric device (N-tester) Yara. The studies were carried out in the conditions of the Moscow region (Russia) on the Mikhailovsky spring barley variety on sod-podzolic medium loamy soils with a high and medium content of phosphorus and potassium and a low content of humus (1.9). The agrometeorological conditions of the growing season of spring barley were characterized by sharp fluctuations in air temperature and the amount of precipitation over decades of the month and in comparison with average long-term observations. Abundant and prolonged precipitation during the grain ripening phase led to lodging in most of the experiments, which affected the yield. To diagnose crops, a model experiment was laid with the introduction of increasing doses of nitrogen fertilizers into pre-sowing cultivation with a step of 30, at which the dose of nitrogen ranged from 30 to 150 kg/ha. Diagnostics was carried out in three phases of vegetation: tube emergence ((Z42), earing (Z55), milk ripeness of grain (Z73) with the Yara N-tester and with the help of stem diagnostics according to the modified method of V. Zerling. The results of photometric diagnostics in the stemming phase (Z42) have a strong correlation with the yield of spring barley grain and with the results of stem diagnostics (R = 0.85). Wherein, the N-tester readings in the earing phase (Z55) and milk ripeness of grain (Z73) with yield R = 0.23 and R = 0.17, respectively, have a weak correlation. This is possibly due to lodging of crops and a change in yield, not as a result of poor plant nutrition, but with difficult mechanized harvesting.

The Impact

Collections of common potato maintained in the field genebanks suffer significant losses due to the impact of extreme environmental factors, diseases and pests. The solution of the problem of safe long-term preservation of common potato accessions is to create doublet in vitro and cryo-collections. Cryogenic collections are stored at ultra-low temperatures in cryobanks. Several methods of potato cryoconservation are known, of which the droplet vitrification method developed by B. Panis with colleagues in 2005 is the most widely used in genebanks. This paper provides a detailed description of the modified method of droplet vitrification, which is used for cryopreservation of apexes (shoot tips) of potato in vitro plants at the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR). The method modified at VIR includes the main steps of the original droplet-vitrification method developed by B. Panis and colleagues: 1) preparation of plant material, 2) isolation of shoot tips, 3) treatment of explants with cryoprotector solutions, 4) freezing/immersion in liquid nitrogen, 5) thawing, 6) post-cryogenic recovery and evaluation of viability and regeneration capacity. The modifications of stages 1, 2 and 6 proposed at VIR lead to a significant reduction in the duration of cryopreservation experiments in comparison with the original method of B. Panis. This paper presents the results of cryopreservation of modern potato cultivars and South American landraces which were obtained using the method of droplet vitrification as modified at VIR. The majority (76.7 %) of the studied accessions of cultivated potato were characterized by high rates of postcryogenic recovery (40–95 %) and 23.3 % of the samples had the values of postcryogenic regeneration from 20 to 39 %, which corresponds to the minimal permissible values for long-term storage in a cryobank. Currently the modified droplet-vitrification method is used for further expanding of the VIR potato cryocollection.

Filling Problem

In order to improve the accuracy of numerical simulation for injection molding process, a modified method for outlet condition was introduced. As the feedstock is regarded as incompressible fluid, the filling ratio should be a linear one with respect to time. But there remains a persistent trouble in previous researches that the linearity is not respected when the filling front approaches near the outlet boundary. The problem is caused by lack of adequate treatment on the outlet boundary. To remedy this defect, the present paper deals with the modeling and realization of suitable condition on outlet boundary for solution of the whole filling process. A simple straight channel mold was taken as an example to prove the proposed simulation method. The result shows that this modified method can suppress the distortion phenomenon and can be valid to realize the correct simulation for the filling of incompressible viscous flow at the ending stage. This long-term filling problem was finally solved.

The maintenance and production of reliable pure cultures with desirable quality is a key operation and the first significant stage in the success of fungal identification. This study assessed spawn preservation and lyophilization (freeze drying) of cultures, for a long time. The sampling was done during the years 2008-2010. Samples were processed in fungal research laboratory of First Fungal Culture Bank of Pakistan (FCBP), Institute of Agricultural Sciences, University of the Punjab, Lahore, Pakistan. Lyophilization has been used to stabilize living cells and fungal isolates, to dehydrate vast range of materials, including foodstuffs, pharmaceuticals, biotechnology products, vaccines, and diagnostic and biological materials, to improve the storage and the quality of DNA after extraction. Long-term maintenance of Penicillium species is essential for detailed studies. Fifty Penicillium species were isolated from different sources by direct and dilution method, and then preserved by spawn and lyophilization technique. Fungal isolates were purified and identified based on their morphology. The viability and purity of the fungal species by fungal spawn and lyophilized material (fungal spawn and fungal mat) were monitored immediately after storage at 1, 2 and 3 months at 4 oC. Each fungal isolate was considered viable if the rate of growth present was the same as that of the original culture and if the morphology of the colony matched the fungal identification documented for each species. All lyophilized Penicillium species were found viable at 1-3 months of storage recovered each time from both type of lyophilized material, fungal spawn and fungal mat and showed the initial colony characteristics and growth rates. Neither stabilizer nor skimmed milk was used in fungal material to protect it from sticking with the walls of the container. Modified method of Penicillium spawn preservation by lyoplilization has been found cost effective in contrast to liquid nitrogen preservation. It was concluded that lyophilization is simple, inexpensive, reliable and effective method for the long term preservation of Penicillium isolates.

Long Term Preservation

SummaryUrokinase (UK), a fibrinolytic enzyme activator purified from human material was immobilized on nylon using different procedures. One was a modified method of immobilization of antigen or antibody initially carried out by Edelman and others in 1971 (Procedure I). The other was our newly devised method (Procedure II) (Sugitachi et al. 1976).Major specificities of the immobilized UK are as follows:1. The UK revealed properties of a plasminogen activator and the optimum pH of the immobilized UK was between 7.2 and 7.4, these values being in good parallel with that of soluble UK. The immobilized UK maintained a stable fibrinolytic activity after long-term preservation and heat-treatment.2. As the fibrinolytic activity of immobilized UK was found to be inhibited by the antiplasmin in human plasma, an antiplasmin inhibitor was immobilized on the nylon together with the UK.The antiplasmin activity was to some extent prevented using this procedure.3. Nylon tubes immobilized with UK and antiplasmin inhibitor were used for thrombotic coagulation studies carried out according to the method of Chandler. Thrombus formation time (TFT) of UK-immobilized tubes was 30 min, while that of the non-treated tubes was no longer than 10 min.
