Impact of Government Initiatives on Total Factor Productivity of Pigeon Pea Cultivation in India
Authors: Monga Sarang , Rana Rajesh K. , Pandit Arun
Published: April 2021

Background: India is the largest producer as well as consumer of pulses in the world due to higher relance of their people on vegetarian sources of proteins, however, we have been dependent on import of pulses for meeting our demand for pulses over several decades. As a strategy to be self-reliant in pulses production two important initiatives were taken by the government of India viz. implementation of Accelerated Pulses Production Program (A3P) and inclusion of pulses in the National Food Security Mission (NFSM-Pulses) during 2010-11. Pigeon pea has tremendous medicinal and pharmacological properties and uses in addition to the good quality source of proteins. Significant improvement observed in production and productivity of pigeon pea after the A3P and NFSM-Pulses was questioned for its Total Factor Productivity (TFP) growth. Methods: This study was designed to assess impact of A3P and NFSM-Pulses on TFP of Pigeon pea in major Indian producing states. TFP was estimated with the help of Malmquist Productivity Index (MPI) using Data Envelopment Analysis Program (DEAP) version-2.1 in five states of India viz., Gujarat, Karnataka, MP, Maharashtra and UP which contribute more than three-fourth pigeon pea production in India. Result: TFP change in period-II (after A3P and NFSM-Pulses) was invariably higher than the TFP change in period-I (before the initiatives) in all the studied states. It indicates that these government initiatives contributed to the enhancement of production and productivity of pigeon pea with the support of better technology adoption rather than just led by higher use of inputs.

Published: April 2021

For the description of spatial distribution of passenger traffic in transport network a correspondence matrix is usually used. The elements of the matrix are the volumes of passenger traffic between each pair of network vertices. The elements of the matrix can be calculated with the use of mathematical apparatus based on the transport gravity model. The correspondence matrix gained by the above mentioned method depends on network structure, model parameters and initial data on the number of incoming and departing passengers for each network vertex. Moreover, the dependence has significantly non-linear character and can’t be presented in explicit form. This complicates the research of common properties of correspondence matrix and forecasting its change at modification of transport network, shift in transport behaviour of passengers (it affects the gravity model parameters) and at random fluctuations of number of incoming and departing passengers for network vertices. At the investigation of the mentioned dependence scientists use various approaches on the basis of both analytical apparatus and approximate methods. The paper presents classic simulation modeling for the analysis of the correspondence matrix and the volume of passenger traffic for the linear transport network calculated on its basis. The use of the proposed approach allowed determining that at random distribution of volumes of incoming and departing passengers the passenger traffic is also a random value distributed according to the normal law. Moreover, the authors gained the dependence between the passenger traffic and the parameter of gravity model connected with the average trip length. Besides, the authors studied the dependence of passenger traffic from the network scale.

Published: April 2021

The paper considers a task of a correspondence matrix recovery for transport with a fixed number of routes according to the statistical data on incoming and departing passenger traffic. A classic gravity model was generalized for several modes of transport that resulted in combination of a correspondence matrix calculation and a calculation of passenger traffic splitting by different modes of transport. The authors propose an approach to determine the correspondence matrix for several modes of transport on the basis of synthetic gravity model with exponential-power gravity function. The approach described is realized on a specific example of analysis of public transport in Ekaterinburg. With the use of numerical methods the authors have solved a task of multidimensional optimization and found optimal values of parameters for gravity function. The paper also presents that the exponential-power gravity function is the most suitable for the model.

Development strategy of railway transport envisages operation of heavy-load trains on the following directions: Kuzbass — Far East (7100 tons), Kuzbass — South, Kuzbass — Centre, Kuzbass — North-West (9000 tons). But the existing rolling stock used for coal transportation doesn’t allow making up trains with the set weight on standard length of receivingand- departure tracks in direction of Far East. That is why the designers and manufacturers of open-box cars got a task to realize a design weight-bearing capacity in the unit of the rolling stock. The task has been solved by the increase of internal dimensions of open-box car body in existing limits by changing bodies design.

Published: April 2021

The paper is devoted to modeling of nonstationary field of a passenger car wheel at braking. The calculation is based on formulation of thermal conductivity equation for the wheel tread as a curved rod with the application of linear approximation of thermal field. At formulation of thermal conductivity equation it is necessary to consider a balance of heat in small volume of tread with the consideration for thermal flow from braking shoe, thermal emission to the environment and thermal conductivity in circular direction. The authors have set for the initial equation of thermal conductivity a functional and have formulated conditions of stationarity that leads after integration to the system of the first order differential equations of time. The authors have applied the Euler method at integration. The developed method has been realized in the C++ program. With the use of this application the authors have conducted a research of the thermal field of the passenger car wheel. The method can be used at designing of new rolling stock and for the analysis of reasons of flaws appearance on the surface of car wheels.

Applying a process approach to optimizing the operation of individual elements of JSC «Russian Railways» will increase the efficiency of the railway industry. We used this method to optimize the operation of the Eastern polygon, which includes four Railways. Process, organizational and functional models are built in the BM automated control system, which is developed on the basis of the ARIS software. The construction process of the Eastern polygon is made in the following order: organizational model of the Eastern site is built; association of the submission of the structures to each other is determined; the organizational model of work of the directorates and services is built, accompanied by models of their functions. The organizational and functional features of the centers for organizing the work of railway stations (DCS), which are engaged in organizing the work of stations that are subordinate to them, are considered. The next step is to build station processes, without which it is impossible to show a complete level-by-level formation of a complex process model for the organization and functioning of the polygon. The optimization is based on a low-level process that affects the overall performance if the technology is applied at all stations in the landfill where the train is attended. For a detailed study and construction of a lower-level model, the Karymskaya station of the Trans-Baikal railway is considered, the stable functioning of which is very important for the efficiency of the entire Eastern polygon. Models of the technology of technical and commercial inspection of transit trains at the station are based on the standard rules for these types of work in force in JSC «Russian Railways». Duplicate operations are identified and measures aimed at optimizing the process model of the lower level - the operation of the station with transit trains are proposed to eliminate them.

The purpose of the article is to develop the basics of managing the interaction of transport universities and enterprises to improve the efficiency of the industry as a result of improving the quality of graduates, and therefore its personnel in general. The article analyzes the features of the organization of relations between a branch university, which differs from a broad-profile classical university, and employers. Modeling of relations between the corporation structural divisions and educational institutions providing educational services is carried out. The mathematical apparatus for describing relationships is selected, indicators of resource satisfaction are proposed, and the resulting one is satisfaction with interaction. To assess the satisfaction of the parties with the results of interaction of relations, a model of resource exchange is proposed. Its use will allow us to get to the quantitative characteristics of the achieved relations. The introduction of the concept of «resource satisfaction» and interaction in its separate areas will help to identify reserves that can be used as a basis for optimizing relationships. The purpose of such modeling is to expand the directions and contacts of universities and industry enterprises, employees' participation in innovation, and improve the quality of university graduates that meets the needs of the industry. In this article, the author is limited to considering the interaction of the «industry University - Russian Railways divisions». In recent years, the university has developed links with many transport organizations that have specific market interaction.

To achieve comfortable operating conditions, the car is equipped with air conditioning. The most common air conditioning devices in transport are air conditioners made on the basis of steam compression refrigerating machines. However, due to the introduction of virtually silent compressors of various capacities on the market, it became possible to return to the use of the simplest and cheapest method of air conditioning – using air-cooled machines. Their use will reduce overall equipment costs, make operation much easier, and increase the reliability of the equipment. The use of sorption refrigerating machines should be considered the most promising, since this will reduce fuel costs by using the energy emitted by the car along with hot exhaust gases.

In the paper, within the scope of the development of tourism, one of its narrower segments is perceived: the health care of the tourist population. The research work has been done in Istria, one of the most outstanding tourist destinations, where scientists and experts have been working intensively on the tourism development forecast up to 2010. In addition to healthy food, clean sea and environment, a tourist has to have certainty that in case of illness he/she will get a service corresponding to the world standards. The concourse of tourism and health care gives answers to the question what should be done to achieve a harmony in the development of both activities, and in this way the general progress of the Croatian State. For the requirements of this paper adaptation possibilities of the health system to the new situation have been researched on the basis of perception of the institutional condition of the health care activity, staff and material supply and equipment for the work in new conditions. In the first part the population health condition is researched on the basis of relevant indicators such as morbidity and mortality of the inhabitants, movement of the number of born and deceased, volume and structure of sick leaves and the like. In the second part an analysis is made and the health care development degree stated for Istria as the tourist resource. On the basis of the entire research work it could be concluded that the health care of Istria has at its disposal staff potential and capital objects that enable a fast adaptation in harmony with the development of tourism.

Background: Real-world data on the molecular epidemiology of EGFR resistance mutations at or after progression with first- or second-generation EGFR-TKIs in patients with advanced NSCLC are lacking. Methods: This ongoing observational study was carried out by 23 hospital-based physicians in Greece. The decision to perform Cobas® EGFR Mutation Test v2 in tissue and/or plasma at disease progression was made before enrollment. For patients with negative/inconclusive T790M plasma-based results, tissue re-biopsy could be performed. Results: Ninety-six (96) eligible patients were consecutively enrolled (median age: 67.8 years) between July-2017 and September-2019. Of the patients, 98% were tested upon progression using plasma and 2% using tissue/cytology biopsy. The T790M mutation was detected in 16.0% of liquid biopsies. Tissue re-biopsy was performed in 22.8% of patients with a T790M-negative plasma result. In total, the T790M positivity rate was 21.9%, not differing between patients on first- or second-generation EGFR-TKI. Higher (≥2) ECOG performance status and longer (≥10 months) time to disease progression following EGFR-TKI treatment initiation were associated with T790M positivity. Conclusions: Results from plasma/tissue-cytology samples in a real-world setting, yielded a T790M positivity rate lower than previous reports. Fewer than one in four patients with negative plasma-based testing underwent tissue re-biopsy, indicating the challenges in routine care settings.

Esse artigo teve como objetivo realizar um levantamento histórico dos componentes curriculares da área de OL da Faculdade de Odontologia de Ribeirão Preto da Universidade de São Paulo (FORP-USP) e analisar o desenvolvimento de suas ementas disciplinares. Foi realizada uma pesquisa documental com abordagem descritiva e qualitativa dos dados da estrutura curricular do curso de graduação da referida instituição entre os anos de 1962 e 2019. Assim, a coleta das informações deu-se utilizando livros e sítios eletrônicos que continham as ementas disciplinares. A disciplina de OL esteve presente no ensino da FORP-USP desde que se tem registro (1962), quando era denominada “Odontologia Legal, Legislação e Ética Profissional”. A área manteve-se vigente, apesar das modificações que culminaram na criação e extinção de determinadas disciplinas. A Odontologia Legal é fundamental na orientação das condutas éticas e legais da profissão e, dessa forma, esteve presente no curso de graduação da FORP-USP desde os primórdios da instituição, e vem sendo trabalhada e desenvolvida com o passar dos anos. Conclui-se que foi possível determinar a trajetória, cronologia e arranjo das alterações das disciplinas relacionadas com a área de Odontologia Legal da FORP-USP a partir de 1962, o que permitiu observar a evolução da área, sobretudo no que diz respeito às metodologias e conteúdos, bem como a diversificação de material bibliográfico utilizado no ensino.

Introdução: Para atender aos aspectos éticos e legais da prática odontológica, faz-se necessário o ensino de conteúdos da área de Odontologia Legal (OL) nos cursos de graduação em Odontologia. As instituições de ensino superior (IES) têm papel fundamental, na condição de fornecedoras das ferramentas e conhecimentos necessários para a atuação responsável do futuro profissional. Objetivo: Verificar se os cursos de Odontologia de faculdades reconhecidas pelo Ministério da Educação na região sudeste brasileira apresentam a disciplina de OL em sua grade curricular e avaliar características curriculares da disciplina. Material e Método: Estudo transversal de base documental, na qual foram analisadas as matrizes curriculares dos cursos de Odontologia das IES localizadas na região sudeste brasileira e que disponibilizavam acesso às grades curriculares via ferramentas on-line. Resultados: Das 176 faculdades, 144 foram incluídas, sendo 125 (86,8%) IES privadas e 19 (13,2%) públicas. A disciplina está presente nas matrizes curriculares de 79,1% das IES. Sobre as características curriculares, majoritariamente a disciplina é ofertada como obrigatória (99%). Em relação à metodologia de ensino empregada, a disciplina é predominantemente teórica (95%). Poucas instituições (5%) ofertam disciplinas teórico-práticas, sendo que IES públicas ofertam mais que IES privadas (p=0,0158). A carga horária média da disciplina é de 50,05h, abaixo da carga horária mínima de 60h recomendada pela Associação Brasileira de Ética e Odontologia Legal. Conclusão: Os resultados deste estudo possibilitaram estabelecer um panorama da inserção da OL nos planos curriculares das IES da região sudeste do Brasil, demonstrando que quando ofertada a disciplina é predominantemente obrigatória e teórica.

A system was proposed to scan dental models to record three-dimensional features seen in the anterior teeth to create a database of dental profiles. Dental casts were randomly selected to create indentations in cowhide leather. Reid Bite Reader was used to measure the bite forces generated by Reynolds Controlled Bite Force Generator to make the teeth impressions. Using the Immersion MicroScribe® 3D, information from the 53 bitemark depressions and 62 sets of dental casts were transferred to an Excel Spreadsheet. Software was developed to perform the 3D comparison using metric and pattern analysis. Statistic analysis showed 100% success when comparing both arches together of the dental casts with the bitemarks or other dental casts.

Problem of estimation of variated frequency of components of polyharmonic signals has been arose. Three-dimensional time-frequency representation of signals is usually used to resolve this problem. But simple and reliable method of instantaneous frequency tracking is needed. Frequency tracking method based on estimation of shifts of peaks of spectrogram has been proposed in this paper. It is assumed that shift of spectral peaks of components of signal is proportional to variation of fundamental frequency. Logarithmic scaling of time-frequency representation is used to make spectral peaks equidistant. Temporal dependence of shift of spectral maximums is obtained using correlation of windowed spectrum at the first frame and spectrum of signal in the current window. Then obtained track is translated in linear scale. Proposed method does not estimate values of instantaneous frequency or central frequency of signal component but estimates its variation. Advantage of the method is that it can estimate frequency track even if range of frequency variation and its central value are known roughly or unknown at all. Multiple components do not interfere to estimate fundamental frequency variation. Reduction of bandwidth is recommended to increase accuracy of frequency track estimation, but analysis of time-frequency representation containing a few components is also possible. Dependency of performance of analysis of synthetic signals using the method on various signal to noise ratios under different conditions was estimated. Applicability of the method for vibrational diagnosing of rotary equipment was checked out using spectral interference method.
Climate vulnerability scenario of the agri-fishery communities in the Bicol River Basin, Philippines

This paper investigated the vulnerability of the agriculture sector and rural agriculture livelihoods in the Bicol River Basin (BRB) of the Philippines to projected changes in climate. The geographical characteristics of the BRB feature eight major sub-basins or watersheds consisting of Libmanan-Pulantuna, Ragay Hills, Thiris, Naga-Yabo, Pawili River, Waras-Lalo, Naporog, and Quinali. The study applied the combination of the participatory tools and the Climate Risk Vulnerability Assessment (CRVA) framework to gather information on local climate vulnerabilities and contexts. Briefly, the CRVA employed geospatial modeling and utilized a number of indicators that are presumed to affect vulnerability including exposure, sensitivity, and adaptive capacity which were aggregated to provide an index of vulnerability. This enabled us to identify areas of exposure and vulnerability and pointed areas of greatest need for strengthened adaptive capacity and risk management. Our findings revealed that vulnerability in the BRB was perceived to be relatively prevalent and that typhoons, flooding, and drought were identified to contribute significant impacts to the rural livelihood. Furthermore, our findings in the CRVA suggested significant regional differences in vulnerability in the BRB. Majority of the towns in the north and central portions of the BRB will largely experience increased vulnerability, particularly, in the Thiris sub-basin including some parts of Ragay Hills, Waras-Lalo, and the northwestern Libmanan-Pulantuna sub-basins. On the contrary, the entire Quinali region on the south revealed to have the lowest vulnerability index. The clear policy implication of these accounts will be on how to mobilize developmental thrusts in both areas of disaster risk reduction and climate change adaptation at the sub-national level to reinforce local-based climate priority setting in adaptation interventions and policies.
