The aim of this study is to investigate the differential impacts of business, government and higher education sectors’ research and development expenditures (R&D) on innovation in OECD countries. Although the business sector has the largest share of the R&D sector due to its profit motive, there are also some efforts made by public and higher education sectors. On the other hand, for decades, the literature of economics is in doubt about the efficiency of the public sector. The study deals with the issue by making a panel data analysis covering 18 OECD countries over the 1981-2016 period and aims to examine the separated effects of these sectoral R&D expenditures on innovation performance. Since most of the existing literature mostly focused on the R&D-GDP relationship, the present study aims to contribute to a relatively untouched point. To obtain robust findings, recent econometric tests and estimators have been used. The previous studies in the existing literature ignored the possibility of cross-sectional dependence problem within the country samples. Ignoring this problem may yield biased and inconsistent results. The present study considers the existence of cross-sectional dependence between selected countries and checks the robustness of each test and estimator via recent econometric techniques. The findings reveal firstly that there is a cointegrating relationship between the number of domestic patents (innovation) and the other three R&D indicators. Secondly, the longrun estimation results imply that increases in the R&D expenditures made by business sector significantly raise innovation while there is no statistically significant evidence on the impact of R&D expenditures made by the government and higher education sectors. The findings reveal that the R&D efforts made by the government and higher education sectors cannot turn into innovation and do not contribute to the knowledge spillover mechanism.

In course of calculation of heat-exchange equipment, major parameters at which heat-exchanging process between heat-carriers runs with possible lesser losses of operational part of heat are defined by methods of thermo-dynamic. In comparison to developed methods of equilibrium processes of actuating mediums heat-exchange calculation, non-equilibrium is at stage of improvement. The research, allowing the defining minimum of entropy production and, accordingly, minimum of exergy losses in non-equilibrium processes of actuating media heat-exchange, is performed. Results of researches are valid both to externally non-equilibrium processes and polytropic. There is defined a dependency of the thermodynamic system entropy growth from the relation of the upper and lower boundary temperatures, independently from the operating media flow process in the heat-exchangers. There is shown that in certain degree of irreversibility the numerical value of which is determined technologically and structurally, there are the relations of thermodynamic parameters for which the operation media heat exchange entropy growth reaches of the minimum numerical value. As confirmation of analysis results example is presented, in which, on several variants, is shown course of entropy production of thermo-dynamic system through minimum that corresponds to the performed research. The carried analysis can find its application both in engineering works and analytical investigations. Bibl. 8, Fig. 1, Tab. 1.

THE MECHANISM OF RAISING AND QUANTIFICATION OF SPECIFIC HEAT FLUX AT BOILING OF NANOFLUIDS IN FREE CONVECTION CONDITIONS
Authors: Moraru V.N.
Published: April 2019

The results of our work and a number of foreign studies indicate that the sharp increase in the heat transfer parameters (specific heat flux q and heat transfer coefficient _) at the boiling of nanofluids as compared to the base liquid (water) is due not only and not so much to the increase of the thermal conductivity of the nanofluids, but an intensification of the boiling process caused by a change in the state of the heating surface, its topological and chemical properties (porosity, roughness, wettability). The latter leads to a change in the internal characteristics of the boiling process and the average temperature of the superheated liquid layer. This circumstance makes it possible, on the basis of physical models of the liquids boiling and taking into account the parameters of the surface state (temperature, pressure) and properties of the coolant (the density and heat capacity of the liquid, the specific heat of vaporization and the heat capacity of the vapor), and also the internal characteristics of the boiling of liquids, to calculate the value of specific heat flux q. In this paper, the difference in the mechanisms of heat transfer during the boiling of single-phase (water) and two-phase nanofluids has been studied and a quantitative estimate of the q values for the boiling of the nanofluid is carried out based on the internal characteristics of the boiling process. The satisfactory agreement of the calculated values with the experimental data is a confirmation that the key factor in the growth of the heat transfer intensity at the boiling of nanofluids is indeed a change in the nature and microrelief of the heating surface.

Published: April 2019

Detail investigation of equilibrium chemical reactions in WO3–H2O system using computer program FacktSage with the aim to establish influence of temperature and quantity of water on formation of compounds of H2WO4 and WO2(OH)2 as well as concomitant them compounds, evaporation products, decomposition and dissociation, that are contained in the program data base were carried out. Calculations in the temperature range from 100 to 3000 °С were carried out. The amount moles of water added to 1 mole of WO3 was varied from 0 to 27. It is found that the obtained data by the melting and evaporation temperatures of single-phase WO3 are in good agreement with the reference data and provide additionally detailed information on the composition of the gas phase. It was shown that under heating of 1 mole single-phase WO3 up to 3000 °С the predominant oxide that exist in gaseous phase is (WO3)2. Reactions of it formation from other oxides ((WO3)3 and (WO3)4) were proposed. It was established that compound H2WO4 is stable and it is decomposed on WO3 and H2O under 121 °C. Tungsten Oxide Hydrate WO2(OH)2 first appears under 400 °С and exists up to 3000 °С. Increasing quantity of Н2О in system leads to decreasing transition temperature of WO3 into both liquid and gaseous phases. It was established that adding to 1 mole WO3 26 mole H2O maximum amount (0,9044–0,9171 mole) WO2(OH)2 under temperatures 1400–1600 °С can be obtained, wherein the melting stage of WO3 is omitted. Obtained data also allowed to state that that from 121 till 400 °С WO3–Н2O the section in the О–W–H ternary system is partially quasi-binary because under these temperatures in the system only WO3 and Н2O are present. Under higher temperatures WO3–Н2O section becomes not quasi-binary since in the reaction products WO3 with Н2O except WO3 and Н2O, there are significant amounts of WO2(OH)2, (WO3)2, (WO3)3, (WO3)4 and a small amount of atoms and other compounds.

قياس وتحليل أثر عجز الموازنة العامة على الدين الخارجي في العراق في أطار التكامل المشترك للمدة (1990 ـ 2016)
Authors: علوان غفران حاتم , طالب ريام علي
Published: April 2019

لقد اصبح مفهوم العجز في الموازنة العامة ظاهرة اقتصادية مزمنة تعاني منها معظم دول العالم سواء أكانت دول متقدمة ام دول نامية , وعلى الرغم من اختلاف رؤى المدارس الاقتصادية من فكرة قبول او رفض العجز في الموازنة العامة الا ان الرأي الذي ساد هو ضرورة حكم دور الدولة من خلال تقليل الانفاق العام الذي ادى الى عجوزات مستمرة في الموازنة العامة ترتب عليها زيادة في الاقتراض الحكومي , وزيادة في الضرائب على الدخل والثروة , مما اضعف الحافز على الاستثمار الخاص , وكذلك اسهم في زيادة الركود التضخمي , واصبح من واجب الدولة تغطية النقص من مصادر التمويل المحلي التي اصبحت من الصعب ان توازي الزيادات المتواصلة في الانفاق العام , فغدت مشكلة التمويل من ابرز المشكلات التي توجهها الدول النامية ولاسيما العراق , مما اجبرها على الاتجاه الى القروض الخارجية التي غالبا ما تكون مشروطة بشروط سياسية واقتصادية معقدة .

  ومن هنا ركز البحث على قياس اثر عجز الموازنة العامة على الدين الخارجي  وتحليلة في اطار التكامل المشترك خلال المدة (1990ـ 2016) , ونتيجة للظروف غير الطبيعية التي مر بها العراق خلال مدة الدراسة فقد أتسمت الموازنة بالعجز نتيجة الزيادة المستمرة في الانفاق العام وترتب عليها زيادة في الدين الخارجي كمصدر من مصادر تمويل هذا العجز , وفي اطار تقدير هذه العلاقة فقد توصلت الباحثة الى وجود علاقة توازنيه طويلة الاجل بين العجز في الموازنة العامة والدين الخارجي .

A Dynamic Ice-structure Interaction Model for Prediction of Ice-induced Vibration
Authors: Wu Tianyu , Qiu Wenliang
Published: April 2019

Sea ice crashing against offshore structures can cause strong ice-induced vibration and have a major impact on offshore structural safety and serviceability. This paper describes a numerical method for the prediction of ice-induced vibration when a vertical offshore structure is subjected to the impact of sea ice. In this approach, negative damping theory and fracture length theory are combined and, along with ice strength-stress rate curve and ice failure length, are coupled to model the internal fluctuating nature of ice load. Considering the elastic deformation of ice and the effect of non-simultaneous crushing failure of local contact between ice and structures, the present ice-induced vibration model is established, and the general features of the interaction process are captured. To verify its efficacy, the presented simulation methodology is subjected to a model test and two full-scale measurements based on referenced studies. Example calculations show good agreement with the results of the model test and full-scale measurements, which directly indicates the validity of the proposed simulation method. In addition, the numerical simulation method can be used in connection with FE programs to perform ice-induced vibration analysis of offshore structures.

Published: April 2019

A atividade leiteira no Rio Grande do Sul está relacionada à agricultura familiar. Esse artigo é baseado em estudo qualitativo que objetiva desenhar as variáveis para o desenvolvimento de sistemas de produção de leite de base ecológica no município de Santa Maria/RS. Foram estudadas sete propriedades produtoras de leite em sistema de Pastoreio Rotativo Voisin (PRV). A experiência trata de um processo de extensão rural diferenciado. As categorias de análise são: PRV, manejo de agroecossistemas, manejo agroecológico de solos, bem-estar animal, relação ser humano-natureza e reprodução social. Os principais avanços percebidos foram o aumento da renda, sistemas sustentáveis de produção e diminuição da penosidade do trabalho. A transição agroecológica dos sistemas de produção de leite de Santa Maria demonstra duas questões centrais: 1) Os referenciais que compõem o sistema agroecológico; 2) A importância de uma extensão rural capaz de realizar uma ruptura e a libertação dos agricultores dos sistemas de produção convencionais, bem como de estabelecer processos contínuos em vez de uma ação fragmentada e pontual.
