Volumetric and Adiabatic Compressibility Behaviour of Aqueous Haemoglobin Solution in Presence of Sugar
Full text linkMeasurements of density, ultrasonic velocity were made for investigating the intermolecular interactions. As D- glucose-Haemoglobin–water systems. These systems were chosen due to their vital role in the life of living organisms for such studies. Using density and ultrasonic velocity data, various derived parameters such as adiabatic compressibility (βs), compressibility lowering (Δβs), relative change in compressibility (Δβs/β0), apparent molal volume (фv), apparent molal adiabatic compressibility (фk), and partial molal volume (фv0), of aqueous Haemoglobin solutions in presence of sugar were obtained for each of the concentrations studied in the temperature range: 303.15-328.15k. Temperature dependence of these data suggests the presence of solute-solute, and solute- solvent interactions as well as on the extent of salvation of the protein molecules in presence of sugar. Therefore, by observing a decrease in the compressibility of the solution and the increase in the apparent molal volume of the protein after the addition of sugar, we can say that the extent of denaturation of protein is reduced and its stabilization was taken place
THE PHILIPPINE MANGO GLOBAL COMPETITIVENESS: A VALUE CHAIN ANALYSIS USING GRAVITY MODEL
No full textThe competitive edge of the Philippines in the global market has been recorded in the trading history. Its contribution to the economy is notable; however trading is limited to fresh mangoes. Likewise, the continuous decrease of area planted to mangoes contributed to its bounded participation in global value chain. Meanwhile, some countries in Southeast Asia emerged in the industry and further threatened the entrance of Philippine mango in the foreign market. This situation will be altered by strengthening the country’s global competitiveness, gross domestic product and implementing policies on remoteness of the country as the result of integrating gravity model using the fixed effect panel regression
Proposed Nonparametric Tests Using Moses Test For Location and Scale Testing
Full text linkThree nonparametric tests are proposed for the simple tree alternative to test for differences in location and/or scale. These tests are combinations of the Fligner-Wolfe test and a modified Moses test. A simulation study is conducted to determine how well the proposed tests maintain their significance levels. Powers are also estimated for the proposed tests under a variety of conditions for three and four populations. Three different types of variable parameters vectors are considered with each vector containing a location and a scale parameter. The first type of parameter vectors considered include different location parameters and equal scale parameters. The second type include different scale parameters and equal location parameters, and the third type include both different location parameters and different scale parameters. Results are given as far as which test does better under certain conditions
Interpretation of the Social Security Principles of the "Beveridge Report"
Full text linkAs a work in the history of social security, the "Beveridge Report" is still very influential. This article introduces the basic principles of the Beveridge Report and analyzes its historical origins to explain its economic Learn the background and social background, and make judgments about its historical limitations

The Specific Characteristics of the Biophysical System Theory
Full text linkBiophysical model can help to see certain phases more clearly and sharply giving way for experimentation. But by all means, the biophysical model is always suitable to correct faults and direct further investigations in the proper way. Another aspect which equally stresses the usefulness of the model on trial: once we keep a solution in hand we get a great number of testing chance through it as well. We can foretell on the basis of the model in what direction a given biological process shall deviate by changing single parameters. There is no sharp limit between compartments and the number of compartments can be increased or diminished by amplification and reduction, respectively. The enlargement and reduction of the compartments depend on the researcher and the compartmentization is confined by Heisenberg’s principle. With the living systems, too, even in the case of very much parameters there exists a critical point, for example the upper limit of the body temperature which goes around 43 oC in the human being. Similarly, there is a critical value for the blood pressure, for the oxygen concentration, etc. These problems belong to the most difficult tasks of the up-to-date science and evenly appear in the most various chapters of the natural sciences. The biogenesis in the univers shows scale behaviour, too: of the cell it is characteristic to be living (it can be cultivated under laboratory conditions), organs built up of cells are living (organ transplantation is possible), organisms built up of organs are also living, according to the most universal law of the biogenesis, life appears on a certain evolutional stage of the universe, in different parts of the space. From the biological point of view the types of interactions are no more so clearly confinable. First of all we can consider the metabolism as a fundamental interaction which realizes the unity of the living organism with its environment. The life under study is disappearing as we proceed from the living whole towards the lifeless constituents. This means that the life does not equal to the sum of its constituents. The more we dissect these living units the farther we get from the biology and finally we reach the superb, eternal and universal physical laws of the lifeless matter
Foreign Economic Relations of Azerbaijan and the Geopolitical Perspectives of Its Development under Modern Conditions
Full text linkThe aim of scientific research is to identify the prospects for foreign economic relations and the continued development of geopolitical interests in the world, increase foreign investment, develop competitive national wealth, uncover the essence and recreate a real picture of foreign economic relations. Considering the growing pace of development of diplomatic and economic relations between the countries of the world, it predetermines the need to create new forms of foreign economic relations of Azerbaijan
Optimal path of a moving service vehicle on network with probabilistic demands
Full text linkIn this paper, I examine twofold problem. The first one is concerned with finding the optimal location of a single facility in a network with demands randomly distributed over the edges. The second problem is about determining the optimal path between two specified nodes of the network of a moving vehicle that continuously interacts with randomly distributed requests for service over the edges. The problems are investigated using different performance measures and probability distributions of the demands
