The influence of mobility and travel distance on access to BC care is multifaceted and should consider the complex interplay of geographic barriers, sociodemographic factors, health system issues, and policy-related challenges. Further research is needed to comprehensively understand the variables impacting access to health services, particularly in LATAM countries, where the challenges women face during treatment remain understudied.

Agriculture is of paramount importance industry which spreads the most and reaches close connection to other industries. Within decades, China has been known as a country with a population of billions and being in high demand for agricultural products. Apart from the above reasons, the geographical position of China is also a great cause for Viet Nam to focus on China’s export market towards selling agricultural products.

Zannichellia L. (Potamogetonaceae) is a widespread aquatic genus that is distributed in temperate and subtropical aquatic ecosystems worldwide. Because the biogeographical location of Iran includes mountain ranges and deserts that may cause different habitat types, it was assumed that these Zannichellia populations would be stronger differentiated than observed in Zannichellia from temperate regions. The present study aimed to test whether Z. palustris would demonstrate high levels of genetic differentiation over long distances and across mountain ranges.

A cross-sectional study was conducted with a total of 5,076 households, with one 15-and-over member in each household selected randomly to answer the questionnaire. Coordinate data of households and tobacco outlets was collected. Smoking status was the main dependent variable. Distance from household to nearest tobacco outlet, and number of tobacco outlets in different radius were calculated using ArcGIS 10.4.1.

Sequence similarity networks are useful for classifying and characterizing biologically important proteins. Threshold-based approaches to similarity network construction using exact distance measures are prohibitively slow to compute and rely on the difficult task of selecting an appropriate threshold, while similarity networks based on approximate distance calculations compromise useful structural information.

In this context Mahalanobis D2 statistic is an effective tool in quantifying the degree of divergence at genetic level and also provides quantitative measure of association between geographic and genetic diversity based on generalized distance (Mahalanobis, 1936). The present study was carried out to ascertain the nature and magnitude of genetic divergence among 52rosellegenotypes.

Over the years, agriculture across the world has been compromised by a succession of devastating epidemics caused by evolving viruses that spilled over from reservoir species or by new variants of classic viruses that acquired new virulence factors or changed their epidemiological patterns. Population genetics can be used as a powerful tool for identification of disease dynamics over population across large-scale geographic regions. Knowledge of life-history and origin of pathogen can greatly benefit from emergence and expansion of spatial genetics.

This article introduces a virtual private network (VPN) system deployed in a 70m2 operator station and greenhouse at Vietnam National University of Agriculture. The VPN system was not limited by geographical distance and allowed for remote monitoring of environmental parameters, viz. light (10- 16000lux), soil moisture (20-100%), temperature (20-60oC), and ambient humidity (30-90%) with tolerances of ± 5% of the set/measured values.

This paper aims to assess the performance of China’s banks by their geographical distribution of loans and deposits, with the application of Generalized Estimating Equation (GEE) method’s multiple linear regression. We chose one of the four largest banks, Agriculture Bank of China, with data from 1990 to 2008 as the sample bank. We identified that branches’ performances in the Yangtze River Delta ranked first and were followed by the Pearl River Delta.

Evaluation of 19 diverse genotypes of cucumber was carried out in a randomized block design for studying genetic divergence. Presence of wide genetic diversity, among the 19 genotypes studied was confirmed by using the powerful tool of Mahalanobis D2 statistic. Based on the interactions in genetic distances 19 genotypes of cucumber got grouped into five separate clusters inferring that the genetic divergence between them was quite plentiful. The mode of distribution of genotypes into various clusters, from different ecogeographical regions viz.

The final coverage and associated performance of an SFN is a joint result of the properties of all transmitters in the SFN. Due to the large number of parameters involved in the process, finding the right configuration is quite complex. The purpose of the paper is to find optimal SFN network configurations for DVB-T2. Offering more options of system parameters than its predecessor DVB-T, DVB-T2 allows large SFN networks. However, self-interference in SFNs gives rise to restrictions on the maximum inter-transmitter distance and the network size.

An experiment was undertaken by utilizing forty finger millet genotypes for eleven yield and yield contributing characters to assess genetic divergence. The analysis of variance has shown that there was significant variation among the genotypes in all the traits. The multivariate analysis carried out using Mahalanobis D2-statistics, indicated wider genetic diversity in the genotypes of finger millet.

Ten SSR markers were used to characterize 22 taro cultivars from North East India. The study revealed that the SSR primers like uq201- 302, Ce1 B03 and Ce1 C06 with PIC=0.82, 0.76 and 0.76 respectively were found to be the most informative markers which can be used for future molecular works on taro. The Jaccard’s similarity coefficient analysis ranging from 0.103 to 0.89 presented high level of genetic distance as no true duplicates were detected. The dendrogram constructed categorized the cultivars into two main clusters I and II.

Brinjal production is threatened by bacterial wilt caused by Ralstonia solanacearum in the developing world. Evaluation in search of best performing genotypes against bacterial wilt disease and incorporating their genes in commercial cultivars is an effective attempt to the problem. Studies on genetic variability and heritability, along with degree of association between the various characters and direct effects of yield contributing characters on total yield, is of paramount significance in framing an appropriate breeding strategy.

Genetic diversity in 13 parental upland cotton genotypes for 13 yield and yield attributing traits was studied using Mahalanobis D2 statistic. The parental hirsutum genotypes grouped in 5 clusters based on the traits investigated. The pattern of grouping of parental genotypes revealed the presence of considerable diversity in the genetic material. The inter cluster distance was greater than intra cluster distance, revealing considerable amount of genetic diversity among parental genotypes investigated.
