O objetivo deste estudo foi avaliar a distribuição das sí­ndromes de polinização e dispersão entre borda e interior e entre os estratos verticais de um fragmento de cerrado sentido restrito, Ribeirão Cascalheira, Mato Grosso, Brasil. Foram estabelecidas cinco transecções de 100 x 4m, paralelas e distantes 100m entre si, onde foram medidos a altura e distância da borda de todos os indiví­duos com diâmetro   altura do solo ââ?°¥ 5cm, considerando borda (primeiros 50m) e interior (últimos 50m) do fragmento. Os indiví­duos foram classificados quanto   posição vertical que ocupam (estratos inferior, intermediário e superior) e quanto  s sí­ndromes de polinização e dispersão. Entre as 69 espécies amostradas, as sí­ndromes de polinização e dispersão mais frequentes foram melitofilia e zoocoria, respectivamente. Ambas foram predominantes tanto na borda como no interior. Em geral, mais de 50% dos indiví­duos localizados na borda e no interior e nos estratos inferior, médio e superior do fragmento tinham sí­ndromes de polinização realizada por abelhas e dispersão por animais. A semelhança entre as sí­ndromes de polinização e dispersão entre borda e interior se deve   elevada similaridade florí­stica entre estes ambientes. A predominância das sí­ndromes de polinização e dispersão realizadas por animais ressalta a importância de corredores ecológicos interligando e consequentemente mantendo a biodiversidade dos fragmentos.

Published: March 2021

Na década de 1970 a região leste do Distrito Federal (DF) foi ocupada por grandes cultivos  agrí­colas, restando hoje poucos remanescentes com vegetação nativa. Em um trecho de reserva, com cerca  de 85 ha de cerrado sentido restrito naquela região (15í°45ââ?¬â?¢13ââ?¬Â - 15í°45ââ?¬â?¢30ââ?¬ÂS; 47í°33ââ?¬â?¢55ââ?¬Â - 47í°32ââ?¬â?¢60ââ?¬ÂW),  contí­gua   áreas agrí­colas, foram feitas coletas florí­sticas esporádicas entre 2009 e 2011. Em 2010 foi  realizado um levantamento fitossociológico do estrato arbóreo, alocando-se aleatoriamente 10 parcelas de  20 m x 50 m. Foram amostrados todos os indiví­duos com diâmetro, medido a 30 cm do solo, ââ?°¥ 5 cm. No  inventário florí­stico foram encontradas 251 espécies, distribuí­das em 157 gêneros e 59 famí­lias, das quais  Fabaceae, Asteraceae e Malpighiaceae foram as mais ricas. Arbustos predominaram, seguidos por árvores,  subarbustos, ervas, trepadeiras e  emiparasitas. Na fitossociologia foram amostradas 72 espécies, 53 gêneros  e 33 famí­lias. Fabaceae e Vochysiaceae foram as mais ricas. A densidade de plantas vivas foi de 1.584 ind./ha, com área basal de 13,96 mí²/ha. Excluindo-se o grupo das árvores mortas (o maior VI), as 12 espécies mais  importantes representaram 50,8% da comunidade, destacando-se Qualea parviflora e Q. grandiflora. Apesar  da alta riqueza a diversidade foi baixa (Hââ?¬â?¢ = 3,18; Jââ?¬â?¢ = 0,74), quando comparada a outras áreas de mesma  fisionomia no DF. Embora antropizada e imersa numa matriz agrí­cola, a reserva estudada ainda mantém  elementos florí­sticos comuns a outras áreas mais preservadas, e conserva espécies cujas populações já foram  extintas em outras localidades do DF e entorno.

O objetivo do estudo foi descrever a florí­stica, estrutura e a diversidade da mata de galeria da ESEC-AE e verificar se nestas matas existe maior diversidade beta da flora arbórea entre: (i) as bacias hidrográficas dos Rios Tocantins e Paraná ou (ii) trechos inundáveis e não inundáveis. Foram alocadas parcelas contí­guas de 100mí² em transecções de 10 metros de largura, perpendiculares a linha principal de  drenagem do terreno. Nas parcelas, todos os indiví­duos lenhosos com circunferência a altura do peito superior a 15,7 cm tiveram o tronco mensurado e a altura vertical estimada. Em cada bacia hidrográfica foram alocadas  24 parcelas, totalizando 48 parcelas ou 0,48 ha de amostra. O método de classificação por TWINSPAN foi utilizado para verificar a diversidade beta dentro da comunidade. Na amostra foram encontradas 118 espéciesarbóreas distribuí­das em 90 gêneros e 47 famí­lias botânicas. Foi estimada densidade de 2317 ind.ha-1, área basal de 33,15 mí².ha-1 e diversidade de 3,99 nats.ind-1. O método de classificação indicou que a comunidade  possui maior variação florí­stica e estrutural (diversidade beta) em função da presença de inundação que em relação   bacia hidrográfica na qual ocorre.

O objetivo foi testar a hipótese de que a variação espacial na cobertura do dossel está relacionada com a composição florí­stica e estrutura do estrato herbáceo-arbustivo de uma floresta estacional semidecidual na transição Cerrado-Amazônia. Foram mostradas 120 parcelas de 2 x 2 m, contabilizados os indiví­duos e estimada a cobertura do dossel, em cada parcela. Foram encontradas 40 espécies, 24 gêneros e 18 famí­lias. Olyra ciliatifolia destacou-se pela elevada densidade relativa (DR= 50,3%). A cobertura do dossel apresentou-se homogênea. Foi encontrada baixa diversidade de espécies (Hââ?¬â?¢= 1,92 e Ds = 0,26) e equabilidade (Jââ?¬â?¢= 0,52), confirmando o que se espera para áreas com dossel homogêneo e baixa luminosidade. Não foi confirmada a hipótese de que a  variação espacial na cobertura de dossel está relacionada com a composição florí­stica e a estrutura do estrato herbáceo. Entretanto, a homogeneidade do dossel pode estar favorecendo a densidade de algumas espécies tolerantes ao sombreamento.

Os aspectos ecológicos a respeito da avifauna no médio e baixo Rio São Bartolomeu se deram através da coleta de dados em 16 pontos, dos quais oito correspondem a ambientes florestais (FL) e oito a ambientes abertos de Cerrado (CS). Os trabalhos de campo resultaram em 96 horas, com 196 espécies distribuí­das em 51 famí­lias, sendo Tyrannidae (30) a mais representativa. Cinco espécies são endêmicas do Cerrado, 11 são tí­picas da Mata Atlântica e duas tí­picas da Floresta Amazônica. A guilda trófica mais representativa foi Insetí­voros (37%). Os ambientes florestais apresentaram maior riqueza de espécies (78) e maior diversidade (H'=4,274; EP=0,981). O ndice de Similaridade ficou abaixo dos 50%, sugerindo uma distribuição mais equilibrada das populações de aves ao longo do Rio São Bartolomeu e uma alta diversidade regional. Os resultados evidenciaram que a grande maioria das espécies (87,7%) explora, de alguma forma, os recursos oferecidos pelos ambientes florestais.

A vegetação arbórea de cerradão (Cd) e cerrado sentido restrito (Cr) foi estudada no Parque Ecológico dos Pequizeiros, DF. Foram alocadas vinte parcelas de 20 x 50 m (dez para cada área), onde todos os indiví­duos lenhosos com DAS30cm ââ?°¥ 5 cm foram amostrados. A densidade total observada no Cd foi de 1.495 ind.ha-1 distribuí­dos em 103 espécies, enquanto no Cr foi de 1.152 ind.ha-1 distribuí­dos em 96 espécies. O í­ndice de diversidade de Shannon (Hââ?¬â?¢) para Cd foi de 3,67 e 3,59 no Cr. A área basal na fitofisionomia florestal foi de 26,28 m2.ha-1e 18,78 m2.ha-1 na formação savânica estudada. Estes valores refletem elevada riqueza e área basal para ambas as áreas. A análise de similaridade evidenciou que as fitofisionomias possuem flora complementar e indicou que a composição florí­stica dos cerradões é resultado da colonização de espécies de fitofisionomias savânicas e florestais adjacentes, assim como por espécies generalistas.

Published: March 2021

Vatairea macrocarpa (Benth) Ducke (Fabaceae - Faboideae) é uma espécie arbórea tí­pica do cerrado latu sensu. Sua floração é bianual e ocorre entre os meses de junho a agosto e a frutificação entre os meses de setembro e outubro. As flores são andromonóicas tí­picas da subfamí­lia Faboideae. A antese é diurna e apresentam néctar como principal recurso floral. As flores foram visitadas por 17 espécies de abelhas, seis espécies de borboletas, quatro espécies de vespideae, por duas espécies de beija-flor e por uma espécie de passeriforme. As visitas iniciam logo ao amanhecer e perduram por todo o dia. Em função do seu comportamento intrafloral, por sua abundância e frequência, as abelhas do gênero Centris e Xylocopa são os polinizadores efetivos de V. macrocarpa, as demais abelhas se comportaram como pilhadoras de recursos florais. V. macrocarpa é auto-incompatí­vel, pois não produziu frutos em experimentos de autopolinização manual e de apomixia.

Hubble parameter in f(R)-gravity
Authors: Zhdanov V. , Stashko O.
Published: March 2021

In view of the famous problem with the “Hubble constant tension” there is a number of approaches to modify the cosmological equations and correspondingly modify Hubble parameter H(z) in order to to relieve the tension between the “early” and “late” Hubble constants. f(R)– gravity is one of such possible modifications. We discuss how to choose the Lagrangian in the f(R)– gravity on account of observational data within the homogeneous isotropic cosmology. The equation is obtained that enable us to derive f(R) for given Hubble parameter H(z). This yields a second order differential equation with corresponding degrees of freedom. If H(z) corresponds to that obtained from usual Friedmann equations, this equation yields a condition for f(R) to mimic the observable quantities of the standard ΛCDM with the above-mentioned freedom. To reduce this freedom on needs additional considerations, which involve the other observable quantities, such as those which appear in considerations of cosmological perturbations on the isotropic and homogeneous background. Also, we consider the reverse problem to find for given f(R). This is fulfilled within an approximation in case of small deviation of f(R) from the General Relativity value.
Mathematical problems associated with errors in estimating distances to galaxies
Authors: Parnovsky S.
Published: March 2021

I generate many mock samples for applying the Monte Carlo method in order to estimate the bias of the Hubble constant because of the use of estimates of distances to galaxies determined from statistical dependences. I add errors to the original sample generated according to the Hubble law. In doing so, I use two possible options for generating errors in distance, having a constant relative error. Both are practical, but there are some math problems with them. I discuss their effect on the properties of the mock sample. The application of the standard least squares method is discussed and shown that it leads to an underestimation of the slope in the Hubble law. A formula is derived for calculating this slope using the maximum likelihood method and it is shown that it is applicable only for one of the variants of the sample noising. All estimates were obtained theoretically, without using the results of mock samples processing, which are described in a separate paper.

In countries like India and China where the population density is very high and the number of vehicles on road keep on increasing every year it presents us with a problem that is monitoring this entire situation and preventing rash driving and accidents and even if they take place there should be immediate action taken to prevent it from happening again and making the roads a safer environment for everyone. To solve this problem, utilized sensors present in the Smartphone specifically the accelerometer sensor to detect the changes in parameters, for this an app was created. The app will read the sensor data that are embedded in the Smartphone and stores the sensors data in the database, The main reason of using the Smartphone is that implementation will be very easy and cost effective as the hardware is already available with everyone and the cost of implementation will be lower when compared to producing an exclusive hardware for this purpose only. The theoretical threshold values for accelerometer sensor data to calculate sudden breaking, sudden acceleration, harsh cornering with the respective axis is used to determine the initial situation. Feeding this data in MATLAB was we use an algorithm developed for this very purpose of analyzing this data.
ANALYSIS OF HEAT TRANSFER MECHANISMS IN THE SOLIDIFICATION OF PCM WITH DIFFERENT PASSIVE ENHANCEMENT TECHNIQUES FOR FREE COOLING APPLICATIONS

Published: March 2021

The continuous increase in the level of green-house gas emissions and the depletion of fossil fuels are identified as the major driving forces behind efforts to effectively utilize different sources of renewable energy.  Free cooling concept is gaining importance in building cooling applications.  The medium which is used to store energy is Phase Change Material.  Among the phase change materials available commercial PCM is of great use.  The only drawback with the PCM is its thermal conductivity is very low.  Various heat-transfer enhancement techniques between the phase change material (PCM) and the heat transfer fluid (HTF) were tried by researchers.  Passive enhancement techniques are very simple and gives good heat transfer enhancement which decreases the solidification time and increases the solidification rate.  In the present work two types of passive enhancement techniques like increasing the roughness of the heat transfer surface and dimples over the heat transfer surface were tried and it has been observed that the dimpled surface will provide better results compared to rough surface over normal surface. Overall there is decrease in solidification time of 37 min. and increase in solidification rate of 19.37% with dimpled surface over normal surface.

Published: March 2021

With the rapid development of digital communication, the demand for spectral resources is increasing and the building of cognitive radios is the right solution for that. Cognitive radio networks are designed to utilize the licensed spectrum when it is not used by the primary licensed users. We are going to propose a method for effective data transmission and streaming in cognitive radio networks. By that we can achieve energy efficiency, less power consumption and much more transmitted information. In this paper, we are going to employ the OFDM method of spectrum sensing and proposed to use Cognitive Radio MAC protocol. Further our main technique is to divide the data packets into different sizes for transmission. The simulation results reveal that there is a better improvement in the detection of idle channel in the cognitive radio network and the delay is reduced with high quality transmission.
Dynamic and Analysis of A Geo-Polymer Concrete Structure
Authors: Et. al. P.Suresh Chandra,
Published: March 2021

The standard portland cement (OPC) was traditionally used as the binding agent in concrete. However it is also important to find alternative emissions-free concrete binding agents to reduce environmental damage caused by cement manufacturing. Geopolymers, also known as inorganic polymers, use byproducts like fly ash rather than cement. Recent studies have shown that geopolymer concrete based on fly ash has enough properties for use. As the geopolymer strength mechanism is different from the OPC binder, an appropriate constituent model for geopolymer concrete must be obtained in order to predict the load-deflection behavior and strength of geopolymer concrete structural components. A number of problems faced with today's cement industry are addressed by geopolymer binders. These binders have similar or better engineering qualities in comparison with cement and can use many types of waste materials.

This project describes the seismic analysis of buildings with high-rise structures, the model of residential G+10 buildings with traditional concrete and geopolymer concrete properties is modelled and analysis is carried out using the response spectra method considering the position of the building in zone III, this analysis would generate the effect of higher vibration modes and real force distribution in elastic range. Test results include maximum story shifts, maximum story drifts, story shears and story stiffness, and an efficient lateral load resistance system, helping to establish whether geo-polymer concrete can be used in high-rise building construction as dynamic loads are included in the high-rise structures

Data Membership Identification using Bloom Filter in Cloud Storage for Effective Resource Allocation
Authors: Et. al. Niraja Jain,
Published: March 2021

Cloud computing has recently been the buzz word that had changed the entire software industry with its PaaS, IaaS and SaaS architecture model. The legacy systems operational in the organizations across different industries have been using the database that had an overhead in terms of cost of data storage, runtime operation and frequent data maintenance. Cloud database concept had challenged the existing storage and operational norms of data. In the distributed environment, resources used in the cloud databases need to identify whether the requested data belongs to the data nodes of a cluster. With databases began to be ubiquitous, the data storage needed to satisfy heterogeneous data structures rather the unstructured data storage support is looked for. The Use of Bloom's filter for data membership identification is the novel approach and can effectively improve the resource organization strategy on cloud. Dynamic resource organization can further improve the query efficiency as well. The concern raised during this is the data privacy which can also be ascertain by maintaining the data access authority levels. Bloom filter uses less memory space against the large dataset to store it's information. A Bloom filter is proposed to be used to determine whether an element is part of a reference set.

Authors: Et. al. Jayashri Patil,
Published: March 2021

The Agriculture plant diseases are responsible for farmer economic losses. These diseases affect on plant root, fruit, leaf, and stem. Detection of disease at early stages helps the farmer to improve productivity. In the traditional system agriculture experts and experienced farmer can recognize the plant diseases at the lower accuracy which causes losses to farmers. Currently several researchers are proposing soft computing and expert systems to recognize plant diseases.  Plant disease identification by visual way is less accurate because some diseases do not have any visible symptoms or some of the diseases appear too late at the time of harvesting. The modern technology in agriculture sector can substantially improve the agriculture production & sustainability. This paper provides a review for fruit disease detection techniques for pomegranate plants. This study includes preprocessing, segmentation, feature extraction and classification techniques for pomegranate fruit diseases detection systems. This paper also states the comparison and limitations of existing fruit disease detection techniques.

HDL Implementation of Scalable Architecture for Packet Classification using Field Split Bit Vector Algorithm
Authors: Et. al. Sandeep Kakde,
Published: March 2021

The categorization of incoming packets can be considered as a classification based on the fields of the different headers, such as the source-Internet protocol, the target-Internet protocol, the source-port, destination-port and protocol fields. It requires that each packet is compared with rules and each packet is forwarded to the highest priority matching rule. Packet classification performance also depends on the rule sets. The required storage depends generally on the number of rules and the size of the method. In this paper, we described a Modular Field Split Bit-Vector (FSBV) algorithm, with which the Field Programmable Gate Array (FPGA) classification of packets is performed using Xilinx ISE13.1 software, with a few predefined rules. From the results obtained through EDA tools, it can be concluded that the proposed technique is memory-efficient and latency aware.

Authors: Et. al. G. Srinivas Reddy,
Published: March 2021

As the usage of internet and web applications emerges faster, security and privacy of the data is the most challenging issue which we are facing, leading to the possibility of being easily damaged. Various conventional techniques are used for privacy preservation like condensation, randomization and tree structure etc., the limitations of the existing approaches are, they are not able to maintain proper balance between the data utility and privacy and it may have the problem with privacy violations. This paper presents an Additive Rotation Perturbation approach for Privacy Preserving Data Mining (PPDM). In this proposed work, various dataset from UCI Machine Learning Repository was collected and it is protected with a New Additive Rotational Perturbation Technique under Privacy Preserving Data Mining. Experimental result shows that the proposed algorithm’s strength is high for all the datasets and it is estimated using the DoV (Difference of Variance) method.

The objects of bioindication of the ecological state were 3 channels of the Volga Delta, located both directly in Astrakhan and in the Astrakhan region. The aim of the work was to conduct a comparative bioelectronic diagnosis of the ecological state of the selected channels with different local anthropogenic loads, both by type and size, based on assessments of the functional state (health) of the bivalve mollusks Anodonta anatina living in them, estimated on the basis of an analysis of their cardiorhythm, measured using an original fiber-optic bioelectronic system. It was found that shellfish selected from different water areas, after 1hour functional load, restore the original heart rate for different times, but in the range from 117 to 166 minutes, which is typical for shellfish living in significantly polluted reservoirs of the same ecological status - "Bad". This characteristic of the water areas completely coincides with the characteristic of the ecological state of the channels of the Volga River Delta specified in the State Report "On the state and on Environmental Protection of the Russian Federation in 2017". The authors proposed and justified the possibility of using the water area of the Gandurino River as a conditional reference for the Volga Delta region. In this case, according to the value of the environmental quality coefficient EQR, the channels of the Urban Branch and the Small Channel can be attributed to the regional environmental status - "Good".
John Steinbeck’in Gazeteciliğine Bugünden Bakmak
Authors: GÜZEL Mehmet

Bu çalışma, dünya çapında romancılığıyla tanınan John Steinbeck’in (1902-1968) daha az bilinen
gazeteci kimliğini ele almaktadır. Steinbeck, Büyük Buhran dönemi romanları başta olmak üzere
kendisini üne kavuşturan eserlerini vermeden önce yıllarca çeşitli gazetelerde muhabirlik yapmış, edebi
yeteneğiyle gazetecilik pratiğini birleştirerek nitelikli eserler vermiş edebi röportaj türünün önde gelen
temsilcilerindendir. İhmal edilmiş konulardan ve detaylardan yola çıkarak özgün hikayeler anlatmayı

In an increasingly competitive environment, brands need to retain existing customers and attract
potential customers. Brands that employ various promotional activities to develop brand loyalty use
different strategies. Especially with the developments in technology and the increase in social media
use, mobile applications have become tools for these promotional activities. From this point of view,
this study aims to examine the importance of mobile applications in creating customer loyalty. For this
purpose, the Starbucks brand, one of the leading coffee chains in the world, was selected. A qualitative
research method, semi-structured interviews, was conducted with 20 participants. While selecting the
participants, customers who fit the definition of “loyal customer” in the literature were chosen. The
question form consisted of two parts. In the first part, information about the participants’ demographic
characteristics was collected, and in the second part, questions related to the purpose of this research
were asked. The findings of the research were examined under the following themes namely; loyalty
drivers of the customers, usage of mobile applications and customer loyalty, and impact of the mobile
application on customer loyalty. Loyalty drivers of the customers were examined under three main
themes as service-related choices, location of the stores, quality and taste. Besides, under the “Servicerelated
choices” theme, internal environment and store atmosphere, and self-service sub-themes were
discussed. As a result, it was revealed that service related choices, quality-taste, and location of the
stores are the drivers that effect customer loyalty. The mobile applications were not used frequently by the consumers yet, and it was not found as a strong indicator of customer loyalty.

Published: March 2021

one of the main problems of music pedagogy was and still is the problem of mastering performing skills by instrumentalist students. This problem is particularly important when students master the modern repertoire, which differs from the classical one by the presence of new techniques and technical difficulties. The purpose of the work is to consider new playing techniques and technical difficulties in works for wind instruments of the twentieth century in the context of pedagogy and education. The results of the study: the modern repertoire, with rare exceptions, is mastered by performing musicians in music and pedagogical universities, and the entire previous period of study is devoted to playing works of baroque, classical and romantic musical styles. University teachers have to deal with students who are not prepared for the perception, understanding, or performance of music of the twentieth century. The novelty of the work consists in methodological recommendations for solving the existing problem.

psychological research is devoted to the study of the nature of the relationship between the indicators of empathy and the level of stress resistance of the personality of a social worker. For the first time, a comparative analysis of test data of respondents by age criterion is presented. Today the profession of a social worker is one of the most widespread in the world and in Russia. As social problems grow in society and the level and quality of life of the population decreases, the number of socially vulnerable categories of the population increases, the profession of a social worker will remain in demand for a long time. The study revealed the danger of the development of emotional burnout and professional deformations of social workers with the aggravation of the sanitary and epidemiological situation with COVID-19. As a result, age-related conditionality in indicators of stress tolerance and empathy among representatives of the “social worker” profession was proved.

Published: March 2021

in the second half of the twentieth century, when the avant-garde proposed truly revolutionary principles for organizing the sound environment, not only the treasures of ancient Russian church music were rediscovered, but also the interest in Russian spiritual culture as a whole, including musical folklore, significantly increased. Russian society at the end of the century was engulfed in disbelief, disappointment, fatigue. Hence there are images of the “decaying” world, the end of the world. The apocalyptic situation manifested itself not only in the fire of civil wars, but also in the feeling of disharmony of people with themselves and with others. As a result, domestic culture began to return to the fold of universal human values, eternal problems and traditional ideas about peace and good. This article considers the basic principles of the implementation of musical folklore in the vocal and instrumental works of domestic avant-garde composers of the second half of the twentieth century. It is noted that neo-folklorism, which arose in domestic music in the 1980–1990s in connection with the idea of national revival, through the semantics of rite, cult archaic, means of folk musical language, strengthened the Russian roots of domestic culture and strengthened the national philosophical heritage embedded in folk music.
