Published: January 2018

The biocompatibility of hydroxyapatite (HA), a lab-made bioglass (BGCaMIX) with high crystallization temperature and different HA/BGCaMIX composites, produced by Spark Plasma Sintering (SPS), was tested with respect to murine osteocytes both by direct and indirect tests, in order to also investigate possible cytotoxic effects of the samples’ extracts. Previous investigations demonstrated that the samples’ bioactivity, evaluated in a simulated body fluid solution (SBF), increased with the increasing amount of BGCaMIX in the sample itself. Although none of the samples were cytotoxic, the findings of the biological evaluation did not confirm those arising from the SBF assay. In particular, the results of direct tests did not show an enhanced “biological performance” of materials with higher glass content. This finding may be due to the high release of ions and particulate from the glass phase. On the contrary, the performance of the BGCaMIX alone is better for the indirect tests, based on filtered samples’ extracts. This work further demonstrates that, when considering bioglasses and HA/bioglass composites, the results of the SBF assays should be interpreted with great care, making sure that the results arising from direct contact tests are integrated with those arising fromthe indirect ones.
Borderline positive antineutrophil cytoplasmic antibodies (ANCA)-PR3/MPO detection in a large cohort tertiary center: lessons learnt from a real-life experience
Authors: Watad Abdulla , Bragazzi Nicola L. , Sharif Kassem , Gilburd Boris , Yavne Yarden , McGonagle Dennis , Amital Howard , Shoenfeld Yehuda
Published: January 2018

Background:

Enzyme-linked immunosorbent assay (ELISA) and indirect immunofluorescence (IIF) are the best strategies for antineutrophil cytoplasmic antibodies (ANCA) detection. In a minority of subjects, ELISA-based ANCA testing may result in a borderline positive titre. Therefore, we assessed the clinical significance of such a result.

Methods:

This is a retrospective study, which included all subjects screened for ANCA subtypes (myeloperoxidase (MPO) or proteinase-3 (PR3)) with subsequent identification of borderline positive results, as determined by ELISA and retested using IIF. The demographic, clinical and laboratory data of subjects with borderline positive ANCA test results were extracted from their medical records.

Results:

A total of 14,555 PR3/MPO-ANCA tests were performed with ELISA during the study period (2006–2016). Of the 14,555 PR3-ANCA antibody tests that were performed, 94 were borderline positive (titre 0.9–1.1), and of 14,555 MPO-ANCA antibody tests, 43 were borderline positive (titre 0.9–1.1). The male-to-female ratio was 1:1.08 and the mean age was 50.95±21.79 years. Four MPO-ANCA (9.30%) and 11 PR3-ANCA (11.70%) antibody borderline samples resulted positive on IIF testing. Subjects with borderline positive MPO-ANCA were found to have a poorer outcome in terms of renal failure and the requirement of dialysis.

Conclusions:

Subjects with borderline positive MPO-ANCA and positive p-ANCA (IIF) seem to have a less favorable outcome. Physicians should be aware of these findings and possibly perform a closer follow-up and routine screening for these subjects.
English and Chinese children’s motion event similarity judgments
Authors: Ji Yinglin , Hohenstein Jill
Published: January 2018

This study explores the relationship between language and thought in similarity judgments by testing how monolingual children who speak languages with partial typological differences in motion description (English and Chinese) respond to visual motion event stimuli. Participants were either Chinese- or English-speaking, 3-year-olds, 8-year-olds and adults (32 in each group) who judged the similarity between caused motion scenes in a match-to-sample task. The results suggest, first of all, that the two younger groups of 3-year-olds are predominantly path-oriented, irrespective of language, as evidenced by their significantly longer fixation on path-match videos rather than manner-match videos in a preferential looking scheme. Using categorical measurement of overt choices, older children and adults also showed a shared tendency of being more path-oriented. However, the analysis using continuous measurement of reaction time revealed significant variations in spatial cognition that can be related to linguistic differences: English speakers tended to be more manner-oriented while Chinese speakers were equally manner- and path-oriented. On the whole, our findings indicate a likelihood that children’s non-linguistic thought is similar prior to internalising the lexicalisation pattern of motion events in their native languages, but shows divergences after such habitual use, thus suggesting that the pattern of non-linguistic thought may be linked, among other things, to linguistic structure.
Disaster Risk Analysis Part 1: The Importance of Including Rare Events
Authors: Etkin David A. , Mamuji Aaida A. , Clarke Lee
Published: January 2018

Rare events or worst-case scenarios are often excluded from disaster risk analysis. Their inclusion can be very challenging, both from methodological and data availability perspectives. We argue that despite these challenges, not including worst-case scenarios in disaster risk analysis seriously underestimates total risk. It is well known that disaster data sets generally have fat tails. In this paper we analyze data for a number of disaster types in order to empirically examine the relative importance of the few most damaging events. The data show consistent fat-tail trends, which suggests that rare events are important to include in a disaster risk analysis given their percentage contributions to cumulative damage. An example of biased risk estimation is demonstrated by a case study of risk analysis of tanker spills off the western coast of Canada. Incorporating worst-case scenarios into disaster risk analysis both reduces the likelihood of developing fantasy planning documents, and has numerous benefits as evidenced by applications of foresight analysis in the public sector. A separate paper "Disaster Risk Analysis Part 2" explores how disaster risk analyses are operationalized in governmental emergency management organizations, and finds evidence of a systemic underestimation of risk.
On finding a cavity in a thermoelastic body using a single displacement measurement over a finite time interval on the surface of the body
Authors: Ikehata Masaru
Published: January 2018

A mathematical formulation of an estimation problem of a cavity inside a three-dimensional thermoelastic body by
using time domain data is considered.
The governing equation of the problem is given by a system of equations in the linear theory of thermoelasticity
which is a coupled system of the elastic wave and heat equations.
A new version of the enclosure method in the time domain which is originally developed for the classical wave equation is established.
For a comparison, the results in the decoupled case are also given.
Ultrasonographic assessment of pubertal breast development in obese children: compliance with the clinic
Authors: Yüce Özge , Sevinç Derya
Published: January 2018

Background:

The aim of the study was to determine the compliance with the clinical and ultrasonographic staging of pubertal breast development in obese children.

Methods:

Fifty-two obese children with Tanner stage 2 and stage 3 breast development accompanied by at least one pubertal clinical finding were included in the study. The staging of breast development was also performed according to the ultrasonographic morphostructural appearance. The subjects were then divided into subgroups according to their clinical and ultrasonographic breast stages. The stages given by both methods were compared for consistency with the hormonal values and other radiological (uterus long diameter, ovary sizes) findings.

Results:

The correlation between the clinical and ultrasonographic staging of pubertal breast development was determined to be weak (r=0.19). Estradiol levels, uterus long diameter and ovary sizes were significantly increased when the ultrasonographic stage increased among the subjects with clinically similar breast development stage. However, no statistical difference was determined in these parameters among the subjects with ultrasonographically similar but clinically different breast development.

Conclusions:

It was shown that the ultrasonographic staging of breast development could provide more accurate and objective data due to the possible mistakes caused in the breast development staging of obese children by their adipose tissue.

Comparison of univariate and multivariate data analysis models for uranium quantification in Trombay historical nuclear waste glass
Authors: Singh Manjeet , Mishra Raman Kumar , Kumar Amar , Kaushik Chetan Parkash , Jaison P.G. , Sarkar Arnab
Published: January 2018

Laser induced breakdown spectroscopy recently has been investigated for analysis of nuclear waste glass for uranium quantification. The initial obtained accuracy and precision was ~15%. In this paper, we have compared the analytical merit of the univariative and multivariative PLSR regression models for the determination of U in barium borosilicate simulated waste glass containing significant amount of U. The analytical merit of a Czerny-Turner spectrograph with high spectral resolution and Echelle spectrograph with broadband spectrum recording capacity were compared using spectra simultaneously record from the same plasma. For univariative calibration the superiority of Czerny-Turner spectrograph over the Echelle has been demonstrated here. Multivariative chemometric PLSR model was found to drastically improve the results. It was also observed that selection of spectral window for analysis significantly affects the analytical merit of multivariative analysis. Echelle though shows relatively inferior analytical merit, but by applying Analytical spectral dependant PLSR in Echelle spectra, a much higher degree of improvement was observed. Using ASD-PLSR and Czerny-Turner spectrograph generated spectra an accuracy and precision of 2–2.5% was achieved in this study.
Preliminary studies on monitoring fouling layers on a charged electrode using Electrical Impedance Spectroscopy
Authors: Anseth Ronnie , Skeie Nils-Olav , Waskaas Magne
Published: January 2018

The objective of the study described in this paper was to examine
whether fouling on an electrode surface can be monitored through
impedance measurements using a modified Electrochemical Impedance
Spectroscopy technique. The attempt was to evaluate a measurement
system that could monitor fouling, within an electrochemical cell, by
using EIS to find one single frequency to measure the impedance
magnitude. An electrical potential difference was applied to the
electrochemical cell to generate an electrical field to accelerate the
deposition layer growth on one electrode. Experimental results show
that the magnitude of the electrochemical cell impedance was in the
range of 110 Ω over the duration of the experiment, which
lasted one week. A measurable change in the impedance magnitude was
detected when a deposition layer, caused by fouling, was present on
one of the electrodes. The measurement frequency was selected
specifically for the purpose to increase the deposition layer
influence on the measured impedance magnitude, which was achieved by
selecting a frequency that kept the capacitive reactance as low as
possible. Results indicate that a measurement system, using one
frequency, is capable of monitoring the deposition layer by measuring
the magnitude of the electrochemical cell impedance.
Crystal structures and Hirshfeld surface analyses of halogen substituted azine derivatives, 1,4-bis(halophenyl)-2,3-diazabuta-1,3-dienes
Authors: de L Correira Nathasha R. , Noguiera Thais C.M. , Pinheiro Alessandra C. , de Souza Marcus V.N. , Gomes Ligia R. , Low John N. , Wardell James L. , Wardell Solange M.S.V.
Published: January 2018

The crystal structures and Hirshfeld surface analyses are reported, from data collected at 100 K, of six 1,4-bis(X,Y-phenyl)-2,3-diazabuta-1,3-dienes (1–6), namely (1: X, Y=H, 4-Cl; 2: X, Y=3,4-Cl2; 3: X, Y=2,4-Cl2; 4: X, Y=H, 2-Br, H; 5: X, Y=H, 3-Br; 6: X, Y=H, 4-Br. The six halogen derivatives crystallise in the monoclinic group P21/c. In each case, the asymmetric unit is one half of the molecule, with the molecules lying across inversion centres, midway between the N–N bonds, with the central C–C=N–N=C–C fragments having all transoid conformations. Each of the six molecules deviates a little from overall planarity. The π···π stacking interactions are the most important intermolecular interactions in each of the six compounds. In the cases of 3 and 4, the π···π stacks are augmented by additional C–X···π (X=Cl or Br) interactions, while in 4, the π···π stacks are linked by weak Br···Br interactions, and in 3, weak Cl···Cl contacts are considered to be also involved in cementing the supra molecular arrangements. The short separations of the layers within the stacks and the extent of the overlaps of the π systems point to significant strengths of the π···π interactions. Comparisons with published structures of related chloro and fluoro compounds indicated similar results: related iodo derivatives, IC6H4CH=N–N=CHC6H4I do not possess as strong π···π interactions. The Hirshfeld analysis indicated further intermolecular contacts which fell outside the normal PLATON cutoff values.

Annotated checklist of the dragonflies (Insecta: Odonata) of the Kaliningrad region, North-Western Russia
Authors: Shapoval N. A. , Shapoval A. P.
Published: January 2018

Unlike adjacent territories (Poland, Lithuania, Latvia), the Kaliningrad region have been poorly studied by far with respect to dragonflies. The first comprehensive surveys on Odonata were made more than 100 years ago, at the beginning of 20th century by La Baume (1908) and especially by Le Roi (1911) and included 50 species. In the following years, no significant publications which particularly address faunistic and taxonomic studies related to the Kaliningrad region were published. Here we present the first modern, most complete checklist of the dragonflies of the Kaliningrad region with notes on the species composition, abundance, and periods of local flight and seasonal migrations. The current checklist is based on data collected by the authors on the Courish Spit (Kaliningrad region, Russia) in 2007-2016. In total, 278 955 specimens belonging to 57 species were recorded. Additional 7 species are included in the list based on the literature data. Thus, the number of species known for the territory of the Kaliningrad region has risen to 64.

Published: January 2018

As a result of exposure to plants of various factors associated with anthropogenesis, a huge amount of pollen grains with altered morphological structures and biochemical properties is produced, which affects its fertility and the normal functioning of phytocoenoses. In the present work, using the example of Pinus sylvestris L. growing on the territory of the city of Barnaul as a model object, the possibility of using the quantitative and qualitative characteristics of pollen of plants depending on the state of the bioindication of the state of the environment (primarily atmospheric air) is substantiated. The data used for the analysis were obtained during the six seasons of flowering of Pinus sylvestris (May–June 2010–2015) in six permanent and nine additional observation points in the city of Barnaul located in the territory with a tense and critical ecological state of the landscapes. An analysis of the quality of the pollen was carried out by selecting it directly from the anthers during the active dusting period. As a control, pollen samples collected in the countryside of the Barnaul pine forest belt, which is an isolated and remote vegetation site relative to the industrial zone of Barnaul and large motor roads, were used. As a result of the research, it was found that the points with the highest pollen sterility and teratomorphic grain areas in the zone of very unfavorable ecological situation, which correspond to the areas of the greatest air pollution. More negative impact is shown in the territories located in an accessible proximity to motorways and parking lots. The proportion of sterile and teratomorphic pollen grains at such points is much higher than the reference values, which indicates a large share of the negative impact of emissions of mobile sources of atmospheric air pollution (vehicles) on the change in the morphological, biological and physical characteristics of Scotch pine pollen. Thus, palynoindication analysis can be one of the methods of bioindication of the state of the environment (primarily atmospheric air), as the most accessible and effective method of research and monitoring.

Crystallization of antibiotics and other biologically active substances from water solutions represents an important stage of their biotechnological production. The process is based on a sharp reduction of a target compound solubility caused by either temperature decrease, or supersaturation of a solution. A preconditioning of a solution, i.e., its evaporation with a simultaneous temperature decrease seems to be an optimal technical solution, especially advantageous for the treatment of thermolabile substances. This paper describes the technology and equipment for the pre-crystallization treatment of solutions of various substances produced by the biotechnological and chemical industries. The proposed preconditioning technology includes ultrasonic dispersion of a solution and formation of an aerosol with a large integral evaporation surface followed by condensation. Comparing to common tubular evaporators used in various industrial processes, this technology provides about equal productivity and, at the same time, lower energy consumption, since it does not require the heating and the further cooling of a solution needed to evaporate and condensate the solvent, respectively, that prevents undesirable effect of high temperature on thermolabile compounds. In addition, the technology prevents the damage of thermolabile compounds, improves the efficiency of the further crystallization process due to the ultrasound-stimulated formation of crystallizing nuclei, and provides a solvent distillate suitable for the further re-use. The designed device for preconditioning has been successfully tested using culture broth of Streptomyces sp. containing a feed antibiotic virginiamycin; such treatment with the further crystallization in standard crystallizers has resulted in the efficient formation of equal-sized antibiotic crystals.
Characterization of minerals content in olive cake and bakery wastes: application in animal nutrition and bio-fuel production
Authors: Al-Rabadi Ghaid
Published: January 2018

Olive cake and bakery wastes are considered as important feed ingredients that are incorporated at different levels in animal diets and can be used in bio-fuel production. Major nutrients of both feed ingredients have been characterized in the literature; however, minerals concentration and extent of variation have been overlooked. The importances of characterization of minerals content and extent of variation between different sources have a significant applications in feed industry and bio-fuel production produced from biomass pyrolysis reactions. The purpose of this study was to investigate minerals composition (Ca, Mg, K, Na, P and S) in olive cake and bakery wastes produced in Jordan and to discuss the results in relation to the average and the extent of variation with tabulated values mostly used in literature. Olive cake and bakery waste samples (twelve samples each) were collected from different olive mills and bakeries distributed in Jordan. Among all analyzed bakery wastes samples, Na had the highest average concentration (0.36%) and ranged from 0.02 to 0.67%, whereas, Mg had the lowest concentration (0.03%) and ranged from 0.01 to 0.05 %. Among all analyzed minerals in bakery wastes, Ca, K and S had the lowest CV% (16.62%, 16.57%, and 16.28%, respectively), whereas, Na had the highest CV% (69.51%). Among all analyzed olive cake samples, this study showed that K had the highest average concentration (0.75%) and ranged from 0.46 to 1.98 %, whereas, Na had the lowest concentration (0.02%) and ranged from 0.01 to 0.03 %. Among all analyzed minerals in olive cake samples, Ca had the lowest CV % (17.48%), whereas, K had the highest CV% (53.41%). It can be concluded from this study that the existed variation in minerals concentrations within the investigated by-products is necessary to recommend minerals supplementation strategies and have applied consequences on optimization bio-fuel production process.

Information on the ecology of the "phage-bacterial host" system is given. The interaction of cultures of lactococci from the collection of the Siberian Research Institute of Cheese with associations of phages was investigated. Infection of sensitive cells with bacteriophage led to cell lysis, which was manifested by negative colonies on the lawn of a lactococcal culture. Characteristics of the biological properties of bacteriophages in the composition of phage associations are given (lytic activity, spectrum of lytic activity, specificity of action). Differentiation of species lysotypes of bacteriophages of mesophilic lactococci, selected at a single cheese enterprise in the Altai Territory was noted. The index of the lytic activity of the investigated phage associations ranged from 0.19 (sample of Lactococcus lactis subsp. Lactis biovar diacetylactis) to 0.24 (sample of Lactococcus lactis subsp. Lactis) from studied strains. The value of the lyotype updated coefficient for the entire array of data varied from 0.25 to 1.00. It is concluded that the specificity of cheese biotechnology together with the evolutionary and genetic determinants of the microworld predetermine a constant high risk of cell phagolysis of starter cultures. Experimental studies confirmed the need to consider the phagocyte of lactic acid bacteria in biotechnology.

Эколого-биологическая характеристика Lactobacillus acidophilus
Authors: Irkitova A. N. , Matsyura A. V.
Published: January 2018

Lactobacillus acidophilus - homofermentative lactobacillus, specializing in living in the gastrointestinal and urogenital tracts of mammals and birds. It accompanies a person from birth and throughout his life, providing a whole range of useful services, the main one of which is active participation in the body's defense system against the harmful action of undesirable microorganisms (preventing the growth of pathogenic bacteria and restraining populations of opportunistic microbes at a safe level) . It is this property of the acidophilus rod that explains its wide practical use in various probiotic products and preparations of dietary, medical and agricultural purposes.
Although the acidophilus rod is known and purposefully used for a long time, it still ha the great potential for the research. The use of gene-molecular approaches has made it possible to clarify the systematic position of L. acidophilus in the family of lactobacilli and to identify a group of closely related species, often indistinguishable by traditional physiological and biochemical identification methods. Today, the efforts of researchers are focused on elucidating the molecular mechanisms by which antagonistically active strains of L. acidophilus carry out a bactericidal and bacteriolytic effect on harmful microbes. Disclosure of these mechanisms will not only allow more efficient selection and use of strains of L. acidophilus, but also create a new class of antibiotics that are more effective and have less side effects than existing ones.
This review is devoted to the description of the probiotic microorganism Lactobacillus acidophilus. In the article the biological and ecological properties of the acidophilus rod are described in detail, examples of practical use of this microorganism in various branches of the national economy are given.

We conducted a retrospective study of EchoCG from 33 males who had the myocardial infarction. Patients with a diagnosis of "neurocirculatory dystonia" (30 people) entered the control group. We studied the size of the left ventricle, the left atrium, the right ventricle, their relationship to each other, the mass of the myocardium and the mass index of the myocardium of the left ventricle. The study of the morphological structures of the heart revealed a change in the size of the left ventricle, the left atrium and the right ventricle in patients who had an acute myocardial infarction, manifested by an increase in the end-diastolic and end-systolic dimensions of the left ventricle, the left atrium, and the right ventricle. In 2/3 of the patients who had an acute myocardial infarction, the normal geometry of the left ventricle was observed. Around one-quarter of the patients had a concentric remodeling (24%), an eccentric hypertrophy of the left ventricle was the least common (15%). The heart of patients who had an acute myocardial infarction demonstrates a lower functionality being compared to the subjects in the control group. In these groups, the maximum value of the DAC / DDR ratio is observed, the ejection fraction is reduced. To a greater extent, the onset of acute myocardial infarction was determined by the size and mass of the left ventricular myocardium. Important meaning had also the body weight, BMI, surface area of the body, the size of the left atrium, and the right ventricle.

Each species besides of having the unique morphological pattern also has an unique ecologo-climatic niche and geographical range. The study of ecologico-climatic and geographic divergence can make significant contribution to understanding of the species genesis and its volume. The purpose of this paper was to compare the ecologo-climatic niches of the closely related species Stipa sareptana and S. krylovii in order to reveal their identity. The research allowed specifying the areas of both species. Using GIS methods and based on the points of presence and six independent bioclimatic characters, their potential ranges – areas where the climatic conditions are favorable for growth – were identified and ecologo-climatic niches revealed. It was established that the most important factors determining the distribution of S. krylovii and S. sareptana are the mean annual temperature and seasonality of precipitation. Other factors play a subordinate role. The comparison of ecological niches, generated by MaxEnt, showed their differences at a statistically significant level.

In this paper, we use Serebyakov's life-form classification to analyze the biomorphological structure of flora growing in Relic Oaks State Reserve (Trans-Baikal Territory). The reserve is located on the territory of Eastern Siberia that belongs to the Pacific Basin. In accordance with the established biogeographical division, this territory is at the boundary between two large floral regions of the Holarctic: Circumboreal and East Asian. It is notable for its phytodiversity and classified as a region with the dominating taiga, taiga-forest-steppe, and forest-steppe plant communities. The biomorphological analysis has shown the predominance of herbaceous plants over xylophytes in the flora of the reserve. Plants with fully or partially lignified shoots account for 11.8% and herbaceous plants, for 88.2% of the total number of flora species in the reserve. Shrubs are the dominating xylophytes on the territory of the reserve and dry-land polycarpous plants are the prevailing herbs. The Relic Oaks Reserve location at the boundary between the forest-steppe and steppe zones causes the predominance of short-rooted, long-rooted, and taproot herbaceous plants.

In order to evaluate the effects of irrigation disruption and Barvar-2 phosphate biofertilizer at different stages of growth on Agronomic Characteristics of Sesame, An experiment was conducted as split plot based on randomized complete block design with three replications in Salmas city, northwest of Iran, during spring of 2016. The main plot was Barvar-2 phosphate biofertilizer at two levels (control or non-biofertilizer and Barvar-2 phosphate biofertilizer) and irrigation disruption as the sub-factor in five levels including control or not irrigation disruption, irrigation disruption at 10 leaf stage, irrigation disruption at flowering stage, irrigation disruption at capsule formation stage, irrigation disruption at grain filling stage was considered. Results indicated that effect of Barvar-2 phosphate biofertilizer on Number of branches per plant, number of capsules per plant, number of seeds per capsule, seed oil percent and seed yield has been significant. The maximum seed yield at 1726.03 kg.ha-1 was observed in Barvar-2 phosphate biofertilizer. Effect of irrigation disruption on Plant height, number of branches per plant, number of capsules per plant, seed number per capsule, seed oil percent and seed yield has been significant. The highest seed yield (1985 kg.ha-1) was observed in control or non irrigation disruption treatment, which did not show significant difference with irrigation disruption treatment at 10 leaf stage. In order to save water irrigation disruption can be recommended at this stage of growth, especially in low water areas. The minimum seed yield was observed at 1214 kg.ha-1 in irrigation disruption treatment at flowering stage.

The development of industrial areas in villages can have many positive socio-economic effects. Results of studies indicate an improvement in the living conditions of villagers after the establishment of industrial areas in villages. Establishment of industrial estates in different provinces of the country has been followed by numerous environmental, economic, social, and physical effects on the region, especially the rural community. Thus, the present study seeks to do a case study concerning the effects of Binaloud Industrial Estate on the sustainability of rural settlements in Ahmadabad district of Mashhad city while considering the place and importance of industrial estates in rural areas. This research is an applied study in terms of purpose, whose results can be used in planning. For measuring the effects of industrial estates, three economic, social and environmental dimensions have been taken into account, which have been evaluated by multiple questions in the questionnaire. Thus, of 58 villages existing in Ahmadabad district of Mashhad city where Binaloud Industrial Estate has been located (research statistical population), 42 villages were selected. To determine the number of sample villages, demographic factor (villages with more than 100 inhabitants) was used. Then, considering the factor of distance dimension and access to Binaloud Industrial Estate, 10 villages were selected out of 42 villages and were used as the population of the research sample. Based on Cochran formula, unlimited population size is used to determine the sample size. Accordingly, the sample size was obtained to be 279. The sample size of each village has been calculated with regard to the proportion of the size of households in each village. In order to compare the average of respondents’ opinions regarding the effect of industrial estates on the sustainability of rural settlements, comparison of the average of this variable (including three economic, social and environmental dimensions) was done with the aid of t-test with number 3 (medium), whose results indicated that p-value divided by 2 of this test is lower than 0.05 and t-statistic is positive (16.732). Hence, it can be concluded that the creation of industrial estates is effective in the sustainability of rural settlements; that is, the research hypothesis is approved with 95% confidence. Ultimately, the impact of the industrial estate on the studied villages is greater in the social and economic dimensions, and in the environmental dimension, the industrial estate has had a significant impact on only 3 villages (Avareshk, Seidabad and Fakhr Davoud).

The studied area is located in southwest of Shahrab village near Ardestan city. This zone is part of Uremia- Dokhtar magmatic belt. Outcrops composed of rhyolite and rhyodacite dome-shaped volcanic complexes are scattered in the studied area; some of which are exploited as ornamental stone. The main rhyolite minerals include quartz, plagioclase and alkali feldspar. Minor minerals include Apatite, Sphene and opaque minerals and of the secondary minerals in these rocks Christie, Chlorite, Epidote and calcite could be mentioned. Calcite exists in rocks in form of filler of micro-fissures. The ignimbrite presence in this group of rocks in form of xenolith is one of the features of this rock group. The main primary texture in rhyolite and rhyodacite is porphyritic and the secondary texture includes pull-apart, snow flake and spherulitic textures. Geochemical evidences indicate that these rocks are sub-alkaline, Calc-alkaline compositions with high potassium and meta-alumina. These rocks have negative EU anomaly that is the feature of acidic igneous rocks. The studied rocks show high enrichment of LREE and LILE elements. The primary magmas constituting these rocks have mantel origin raised under extreme compressional conditions on continental crust in a tectonic environment of volcanic arc. It seems that these rocks are formed in connection with continuance of volcanic activities associated with subduction of Neolithic oceanic plate beneath continental plate of Iran.

One of the main limiting factors in crop production in different regions of Iran is water deficit stress. Mycorrhiza and vermicompost fertilizer may be help plants to uptake more water. Therefore, a greenhouse experiment was carried out in factorial design that was carried out to evaluate the effect of Mycorrhiza, vermicompost fertilizer and water deficit stress on some physiological traits of sweet basil (Ocimum basilicum L.). Factors included Mycorrhiza (inoculation and non-inoculation), Vermicompost fertilizer (0, 30, 50, and 70 percentage of pod volume), and water deficit stress factor included irrigating up to 60% of F.C as water deficit stress treatment, up to 75% of F.C as mild water deficit stress treatment and up to 90% of F.C as well irrigated treatment. The results showed that sugars and proline increased with increasing water deficit stress, while higher vermicompost consumption decreased the severity of the increase. Merging vermicompost, and mycorrhiza, had a synergistic effect on the catalase enzyme and chlorophyl a+b. Significant negative and positive relationships were found between shoot dry weight and proline with water deficit stress. In addition, basil plant physiological responses to drought stress showed that this stress-sensitive plants, tried to adjust to stress, through osmotic adjustment and increasing antioxidant activity. The results totally showed that merging mycorrhizal inoculation and vermicompost mitigate the effects of drought stress in Basil.

Published: January 2018

In the recent century, the excessive and unplanned growth of urbanism and inattention to the proper and correct selection of locations for roadside uses, especially roadside services, have led to the appearance of problems such as lack of spaces for service centers, inappropriate access, and other problems. The strategic location of the city of Zahedan among other cities of Sistan and Baluchistan Province and its connection to the national corridors requires development and growth of transportation industry and improvement of its performance. Some of the utmost important centers that have to be established for this purpose on the roadsides in the required quantities are roadside service and welfare centers. Therefore, in order to maintain and promote the security of the roads in the country, the establishment of such centers requires studies, evaluations and eventually, determination of appropriate and secure locations. In this study, considering the necessity of establishing service and welfare centers on the Zahedan to Khash Road, first, the existing centers were evaluated from the perspectives of passengers, then, by the use of site selection systems, some locations were determined in the high traffic parts of this road. The research methodology in this study is descriptive-analytical which is used in order to analyze the collected data. The research findings show that according to the passengers, the conditions of roadside services on the Zahedan to Khash Road and the existing infrastructures are weak. However, they are satisfied with social and security-related factors. The passengers also stated that these roadside service centers have created job opportunities in the region. They also have been effective in providing security of the roads.

The study of suspended solids in the West Siberian rivers is of great importance from the point of view of biogeochemistry, since in the rivers there are the formation and transformation of abrasion products of banks and bottom, suspended and dissolved organic matter and solid river flow, which are carried out from the land to the Kara Sea and further to the North Arctic Ocean. Studies of river suspension are necessary to understand the processes of modern sedimentation, as well as for the ecological assessment of the water area state. Mechanisms of sedimentation are largely associated with the processes of physical and biological weathering, generation, transformation and transport of suspended matter from the catchment to floodplain landscapes. In this regard, the role of studying the connection of the qualitative composition of river suspended matter with landscape parameters (level of the catchment area swappiness, nature of the soil cover, composition of soil-forming rocks, presence (absence) of permafrost, etc. is high. For example, the river of the north-taiga subzone, the catchment area of which is heavily swamped, and the river of the tundra zone with a slightly swampy watershed are represented. The influence of flood waters on the concentration of some elements in rivers with contrasting watersheds is considered. The contribution of groundwater and the effect of soil solutions on the overall migration flow are estimated.
