ENTRE IDENTIDADES E MICRORRESISTÊNCIAS: ONDE ESTÃO AS LÉSBICAS?
Authors: Wermuth Maiquel Ângelo Dezordi , Canciani Pamela
Published: April 2018

A relação com o corpo excede o domínio do particular, já que os sujeitos estão inseridos em contextos socioculturais, transitando em direção ao público, e assumem suas individuações a partir do contato com os outros. Dessa forma, para que haja visibilidade da existência lésbica, verifica-se a necessidade de superação, primeiramente, de padrões imputados pelo sistema patriarcal e, em um segundo momento, de um apagamento social sofrido pelas mulheres lésbicas no decorrer da história. Essa pesquisa se justifica pela urgência de rompimento de estereótipos e estigmas que permeiam a identidade lésbica: ao se (re)conhecer a diferença no meio acadêmico, também é possível vislumbrar uma mudança cultural e social, depois de ultrapassada a invisibilidade imposta a essas mulheres. O método de pesquisa a ser utilizado será o hipotético-dedutivo. A técnica empregada será a pesquisa bibliográfica, a partir de consultas em livros, artigos científicos, revistas, legislações e demais documentos pertinentes.
A BUSCA DO EQUILÍBRIO ENTRE A POSITIVIDADE DO DIREITO E A REALIZAÇÃO DA JUSTIÇA: UMA VISÃO RADBRUCHIANA
Authors: França Mhardoqueu G. Lima
Published: April 2018

Em tempos de pouca crença na lei positivada em razão de decisões judiciais que, às vezes, a contraria, importante se faz lançar luz a uma discussão antiga, mas ainda relevante, que é a harmonia entre segurança jurídica e justiça. Nessa perspectiva, o objetivo desse artigo é traçar meios para equilibrar nos pratos da balança os elementos segurança jurídica e a justiça. Como marco teórico da pesquisa foi utilizado o pensamento do jusfilósofo Gustav Radbruch. A metodologia utilizada foi a jurídico-compreensiva e exploratória, tendo como fonte de pesquisa livros, artigos específicos e jurisprudência. Tudo isso, permitiu alcançar o resultado de que é imprescindível a necessidade de se harmonizar a segurança jurídica e a justiça. E se concluiu que no universo do pensamento radbruchiano a fórmula da injustiça extrema dá o equilíbrio necessário entre os elementos, segurança jurídica e justiça, da ideia de direito de Radbruch, levando em consideração a necessidade do direito positivo, mas com vistas a alcançar a justiça.

Children and consent: the key issues: Part II
Authors: Parkhouse Julia
Published: April 2018

Gaining a valid consent from a patient is an area of law that has developed in recent years. Based on the principle that patients should have autonomy over their own bodies, and provided an adult has the capacity to make a decision, a patient has the right to give or refuse permission to a healthcare professional who may wish to provide care or treatment to them. The issue, however, is complicated when dealing with patients under the age of 18. In the second of two articles, Julia Parkhouse discusses consent to treatment and children under 16 years, and those aged 16 and 17 years, and the complex issue of such children refusing treatment.

Precision Spraying Model Based on Kinect Sensor for Orchard Applications
Authors: Gao Guandong , Xiao Ke , Li Jianping
Published: April 2018

ABSTRACT. This study describes the use of an integrated Kinect video sensor in a spray system to capture color and depth information to improve the efficiency of spraying in an orchard. Equations for calculating the optimal spray distance and pattern based on data collected by the video sensor are proposed, in conjunction with the leaf wall area density, to address the difficulty in estimating the dose of sprayed chemicals. First, to estimate the optimal distance and route, this study designs a spray system using the Kinect integrated video sensor and proposes an equation for calculating the leaf wall distance of fruit trees for spraying. Second, to control the dose of sprayed chemicals by adjusting the nozzle angle and rate of flow, this study proposes the concept of leaf wall area density and analyzes the leaf area shapes of peach, apricot and grapevine, which are fan shaped, round and square, respectively. Finally, the results of the experiment on peach trees, apricot trees and grapevines demonstrated that the intelligent orchard chemical precision spray model established based on the spray distance and the leaf wall area density can adjust the system to the optimal spray distance and dose, which can improve efficiency in spraying chemicals, increasing the economic benefits for fruit farmers. Keywords: Integrated sensor, Kinect, Leaf wall area density, Optimal spray distance.
Quantification of the Extracellular Matrix Molecule Thrombospondin 1 and Its Pericellular Association in the Brain Using a Semiautomated Computerized Approach
Authors: Liu Jessie R. , Modo Michel
Published: April 2018

The structure and functions of the extracellular matrix (ECM), its spatial distribution and pericellular association of ECM molecules remain poorly understood. Colocalization of ECM molecules with cell phenotypes through immunohistochemistry can provide crucial insights into their juxtacrine signaling role as well as their structural relevance to tissue architecture. As manual quantification of images introduces intra- and inter-user bias and is cumbersome for high-throughput approaches, we implemented an automated high-throughput method to quantify the spatial distribution and cellular association of one ECM molecule, thrombospondin 1 (TSP1) with two major cell phenotypes, neurons, and astrocytes. The distribution of TSP1 was homogeneous throughout the striatum and cortex along the anterior–posterior axis. TSP1 occupied 8.85% of the striatum and 7.40% in the cortex. TSP1 also associated with 94.58% and 88.45% of neurons in the striatum and cortex. The association with astrocytes was significantly lower at 47.55% and 28.09%. These findings highlight the key role that TSP1 plays in neuron physiology in a healthy brain, but also highlights key regional difference in astrocytes secreting ECM molecules. The semiautomated approach implemented here will improve the throughput and reliability of measuring the distribution and cellular colocalization of ECM molecules.
Vase life of cut Lilium pumilum inflorescences with salicylic acid
Authors: Santos Mirelle Nayana , Tolentino Márcia Martins , Mapeli Ana Maria
Published: April 2018

The demand for flowers and ornamental plants has significantly increased in recent years. However, in most cases, the production of such species is accompanied by inappropriate postharvest handling, which is responsible for significant losses of marketed flowers. Lilium pumilum, a member of the family Liliaceae, is one of the ornamental species with economic potential as potted or cut flower, which features long stalks containing orange inflorescences with several flower buds and numerous smooth as well as linear leaves. Due the high perishability of this product, appropriate techniques that extend flower longevity should be employed. The present study was developed to evaluate the effect of salicylic acid (SA) on the postharvest preservation of L. pumilum inflorescences. Stalks were kept in maintenance solution with different concentrations of SA (0, 1, 5 and 10 mM) for 0, 6, 12, 18 and 24 h. The L. pumilum flowers had longevity decreased by 57.8 and 63.1% when kept in 5 and 10 mM SA, respectively, compared with control. This effect may be associated with the observed decrease in the percentages of flower opening and chlorophyll content as well as the damping-off of stalks, indicating phytotoxicity. Therefore, the use of 5 and 10 mM SA is inefficient to extend the longevity of L. pumilum.
Contribution méthodologique à l’analyse des mouvements résidentiels intercommunaux wallons par la construction de bassins résidentiels (1994-2014)
Authors: Charlier Julien , Debuisson Marc , Duprez Jean-Paul , Reginster Isabelle
Published: April 2018

Résumé

Cet article présente l’analyse des mouvements résidentiels intercommunaux en Wallonie sur une période de 20 ans, à partir de données exhaustives. Un exercice de synthèse de ces déménagements est proposé avec l’adaptation d’une méthodologie hiérarchique développée par l’INSEE (Institut de statistique français) pour construire des regroupements d’entités spatiales sur base de données de flux migratoires dans la région Sud de la Belgique, la Wallonie. À partir de données reprenant l’ensemble des déménagements (migrations résidentielles) enregistrés entre communes belges (Local Administrative Units (LAU) 2 selon Eurostat) de 1994 à 2014, la méthodologie permet de rassembler les entités en bassins sur base de l’importance des échanges migratoires que les entités entretiennent entre elles. Plusieurs choix méthodologi­ques ont été posés pour proposer un découpage de la Wallonie en 11 «bassins résidentiels». Un bassin résidentiel correspond au territoire théorique dans lequel les individus (et par extension les ménages) à la recherche d’une nouvelle localisation résidentielle ont tendance à migrer pour répondre à leurs aspirations en termes de logement, en tenant compte de leurs réseaux sociaux et/ou professionnels et des contraintes de coûts du logement et des déplacements. Cette approche permet à la fois de synthétiser la matrice origine-destination entre toutes les entités d’un territoire, mais également de mieux comprendre la structuration de celui-ci.

Abstract

This article is about residential migrations between municipalities (Eurostat Local Administrative Units (LAU) 2) in Wallonia, the southern region of Belgium. Based on a hierarchical methodology developed by INSEE (French National Institute of Statistics), residential migrations are synthetized so as to build clusters of municipalities that can be grouped together on the basis of their migration flows in the southern region of Belgium, Wallonia. Using data on all migration flows between municipalities in the period from 1994 to 2014, the methodology allows grouping municipalities based on the migratory exchange rates between them. Several choices have been made that lead to a new spatial division of Wallonia in 11 residential catchment areas. Such an area can be defined as a territory on which a person looking for a new residential location is ready to move as such a move would not interfere with his/her social and/or professional networks and would also respect cost constraints related to housing and commuting. This approach allows synthetising migration flows between all municipalities but also a better understanding of the spatial structure of Wallonia.

Authors: Bouzón Alberto , Acea Benigno , Soler Rafaela , Iglesias Ángela , Santiago Paz , Mosquera Joaquín , Calvo Lourdes , Seoane-Pillado Teresa , García Alejandra
Published: April 2018

Background

The aim, of the study was to estimate the accuracy of magnetic resonance imaging (MRI) in assessing residual disease in breast cancer patients receiving neoadjuvant chemotherapy (NAC) and to identify the clinico-pathological factors that affect the diagnostic accuracy of breast MRI to determine residual tumour size following NAC.

Patients and methods

91 breast cancer patients undergoing NAC (92 breast lesions) were included in the study. Breast MRI was performed at baseline and after completion of NAC. Treatment response was evaluated by MRI and histopathological examination to investigate the ability of MRI to predict tumour response. Residual tumour size was measured on post-treatment MRI and compared with pathology in 89 lesions. Clinicopathological factors were analyzed to compare MRI-pathologic size differences.

Results

The overall sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for diagnosing invasive residual disease by using MRI were 75.00%, 78.57%, 88.89%, 57.89%, and 76.09% respectively. The Pearson’s correlation coefficient (r) between tumour sizes determined by MRI and pathology was r = 0.648 (p < 0.001). The size discrepancy was significantly lower in cancers with initial MRI size ≤ 5 cm (p = 0.050), in cancers with high tumour grade (p < 0.001), and in patients with hormonal receptor-negative cancer (p = 0.033).

Conclusions

MRI is an accurate tool for evaluating tumour response after NAC. The accuracy of MRI in estimating residual tumour size varies with the baseline MRI tumour size, the tumour grade and the hormonal receptor status.
Combined local and systemic bleomycin administration in electrochemotherapy to reduce the number of treatment sessions
Authors: Maglietti Felipe , Tellado Matias , Olaiz Nahuel , Michinski Sebastian , Marshall Guillermo
Published: April 2018

Background

Electrochemotherapy (ECT), a medical treatment widely used in human patients for tumor treatment, increases bleomycin toxicity by 1000 fold in the treated area with an objective response rate of around 80%. Despite its high response rate, there are still 20% of cases in which the patients are not responding. This could be ascribed to the fact that bleomycin, when administered systemically, is not reaching the whole tumor mass properly because of the characteristics of tumor vascularization, in which case local administration could cover areas that are unreachable by systemic administration.

Patients and methods

We propose combined bleomycin administration, both systemic and local, using companion animals as models. We selected 22 canine patients which failed to achieve a complete response after an ECT treatment session. Eleven underwent another standard ECT session (control group), while 11 received a combined local and systemic administration of bleomycin in the second treatment session.

Results

According to the WHO criteria, the response rates in the combined administration group were: complete response (CR) 54% (6), partial response (PR) 36% (4), stable disease (SD) 10% (1). In the control group, these were: CR 0% (0), PR 19% (2), SD 63% (7), progressive disease (PD) 18% (2). In the combined group 91% objective responses (CR+PR) were obtained. In the control group 19% objective responses were obtained. The difference in the response rate between the treatment groups was significant (p < 0.01).

Conclusions

Combined local and systemic bleomycin administration was effective in previously to ECT non responding canine patients. The results indicate that this approach could be useful and effective in specific population of patients and reduce the number of treatment sessions needed to obtain an objective response.

Regulation of Global Transcription in Escherichia coli by Rsd and 6S RNA
Authors: Lal Avantika , Krishna Sandeep , Seshasayee Aswin Sai Narain
Published: April 2018

In Escherichia coli, the sigma factor σ70 directs RNA polymerase to transcribe growth-related genes, while σ38 directs transcription of stress response genes during stationary phase. Two molecules hypothesized to regulate RNA polymerase are the protein Rsd, which binds to σ70, and the non-coding 6S RNA which binds to the RNA polymerase-σ70 holoenzyme. Despite multiple studies, the functions of Rsd and 6S RNA remain controversial. Here we use RNA-Seq in five phases of growth to elucidate their function on a genome-wide scale. We show that Rsd and 6S RNA facilitate σ38 activity throughout bacterial growth, while 6S RNA also regulates widely different genes depending upon growth phase. We discover novel interactions between 6S RNA and Rsd and show widespread expression changes in a strain lacking both regulators. Finally, we present a mathematical model of transcription which highlights the crosstalk between Rsd and 6S RNA as a crucial factor in controlling sigma factor competition and global gene expression.

Straipsnyje siekiama parodyti, kodėl reikia atmesti populiarią fenomenologijos sampratą, pagal kurią fenomenologija yra pirmąja asmens perspektyva paremta refleksija. Straipsnyje argumentuojama, kad tyrinėjimas gali būti įvardijamas kaip fenomenologinis huserliškąja prasme, jeigu ir tik jeigu jis yra paremtas trimis pamatiniais fenomenologiniais principais – epoché, fenomenologine redukcija ir eidetine variacija – suprantant juos kaip nepakeičiamus fenomenologinius principus, sudarančius grynosios fenomenologijos pamatą. Šie trys fenomenologiniai principai yra būtini, bet nepakankami: jie turi būti papildyti faktinės variacijos principu. Straipsnyje pristatoma pozicija, kad faktinės variacijos inkorporavimas į fenomenologinių tyrinėjimų lauką transformuoja grynąją fenomenologiją į dialoginę fenomenologiją.

The studied patterns in the microstructure are spheronization, decarburization and graphitization. The microstructure is revealed from microscope images obtained in the Testing Laboratory Equipment and Materials of the Federal Electricity Commission in Mexico (LAPEM-CFE). The proposed system compared to the human expert, obtained an accuracy of 96.83 % with a shorter analysis time and inspection cost.
Internal volumetric heat generation and heat capacity prediction during a material electromagnetic treatment process using hybrid algorithms
Authors: García-Morantes Edgar , Amaya-Contreras Iván , Correa-Cely Rodrigo
Published: April 2018

This work considers the estimation of internal volumetric heat generation, as well as the heat capacity of a solid spherical sample, heated by a homogeneous, time-varying electromagnetic field. To that end, the numerical strategy solves the corresponding inverse problem. Three functional forms (linear, sinusoidal, and exponential) for the electromagnetic field were considered. White Gaussian noise was incorporated into the theoretical temperature profile (i.e. the solution of the direct problem) to simulate a more realistic situation. Temperature was pretended to be read through four sensors. The inverse problem was solved through three different kinds of approach: using a traditional optimizer, using modern techniques, and using a mixture of both. In the first case, we used a traditional, deterministic Levenberg-Marquardt (LM) algorithm. In the second one, we considered three stochastic algorithms: Spiral Optimization Algorithm (SOA), Vortex Search (VS), and Weighted Attraction Method (WAM). In the final case, we proposed a hybrid between LM and the metaheuristics algorithms. Results show that LM converges to the expected solutions only if the initial conditions (IC) are within a limited range. Oppositely, metaheuristics converge in a wide range of IC but exhibit low accuracy. The hybrid approaches converge and improve the accuracy obtained with the metaheuristics. The difference between expected and obtained values, as well as the RMS errors, are reported and compared for all three methods.

Design and construction of a quantitative model for the management of technology transfer at the Mexican ele-mentary school system
Authors: Alfaro Ponce Mariel , Muñoz Ibañez Crsitopher Antonio , Gayosso Mexia Sonia
Published: April 2018

Nowadays, schools in Mexico have financial autonomy to invest in infrastructure, although they must adjust their spending to national education projects. This represents a challenge, since it is complex to predict the effectiveness that an ICT (Information and Communication Technology) project will have in certain areas of the country that do not even have the necessary infrastructure to start up. To address this problem, it is important to provide schools with a System for Technological Management (STM), that allows them to identify, select, acquire, adopt and assimilate technologies. In this paper, the implementation of a quantitative model applied to a STM is presented. The quantitative model employs parameters of schools, regarding basic infrastructure such as essential services, computer devices, and connectivity, among others. The results of the proposed system are presented, where from the 5 possible points for the correct transfer, only 3.07 are obtained, where the highest is close to 0.88 with the availability of electric energy and the lowest is with the internet connectivity and availability with a 0.36 and 0.39 respectively which can strongly condition the success of the program.

The analysis is based on data collected by means of an online survey conducted in Croatia on a sample of 400 employees of private and public sector organizations. The results presented in the paper show that clarity is rated the highest, while supportability is the lowest-rated ethical virtue in the aforementioned organizations. Ethical culture as a whole is a good predictor of work motivation, with congruence of the management being the most important predictor. An interesting fi nding of this study is also a negative association between sanctionability and work motivation when all other predictors are being held constant. It is thus concluded that the CEV model represents a good measurement tool with a proven construct validity outside its original social and cultural context. The paper closes with suggestions for future research, especially for a possible broadening of the application of the CEV model.

The effect of salinity and NO3: NH4 ratio (0:100, 75: 25, 50:50, and 25:75) in the nutrient solution on growth, yield quality and N metabolism in hydroponically grow canola (Brassica napus L.) was evaluation. Both fresh and dry weights of leaves were significantly lower when a high concentration of either NO3 (100%) or NH4 (75%) was the sole N source in the nutrient solution. In nonsaline condition, increasing of both NH4 and NO3 ratio in the nutrient solution reduced photosynthetic (pn) rate, however in salinity condition the reduction of pn became more pronounced at a higher ratio of NH4 in the nutrient solution. The yield in terms of fresh and dry weight of seed per plant was significantly increased at the 75:25 (NO3: NH4) treatments. Total fat in nonsaline condition was increased with increasing NH4 ratio in the nutrient solution, however in saline condition it was reduced, at high NH4 ratio in the nutrient solution. The increase of tissue N concentration was nearly proportional to the NH4 concentration in the nutrient solution.The activity of nitrate reductase (NR) was increased by increasing NH4 form 0 to 50% and then reduced at a higher ratio of NH4 in the solution. Salinity increased NH4 concentration so that the saline condition had nearly twice high NH4 concentration in the leaves. The increase of NH4 concentration induced by salinity could be parially the reduction of NH4 assimilate because of the shortage of carbohydrate.
Desiccation Stress and the Effect of Humidity in Mosses
Authors: FAJUKE Aina Arinola
Published: April 2018

Mosses show fair degree of structural adaptations to different environmental conditions. The effects caused by desiccation were determined in the shoots of six moss species, collected from various locations of the Obafemi Awolowo University Ile-Ife campus, Osun State, Nigeria. Using 0.1 g of fresh weights, desiccation of moss species over time at 0%, 52%, and 100% relative humidity, were determined by putting the shoots into desiccators and reweighing at intervals of 15 min, 30 min, 1 hr and on the 8th day. It was concluded that the locations of the moss species, and the fact that the cell walls of all the mosses were thick, were regarded as the adaptations which helped these mosses survived desiccation stress.

In order to evaluate the biological effect and interference of crop and weed in canola-faba bean intercropping in comparison with mono culture, an experiment was conducted in randomize completely blocks design with three replication at Ramin Agriculture and Natural Resources, University. In this experiment treatments were different compositions of canola (Brassica napus L. var. haylo) and faba bean (local cultivar). Plant densities (0, 20 and 40 plants per m2) for canola and four levels include (0, 20, 40 and 60 plants per m2) for faba bean in accordance with additive form mixed culture system respectively. Weed dry weight was affected by culture system and different levels of plant densities in mixed culture and there were significant difference 1%. Lowest weed dry weight was obtained in 20-60 and 40-60 plants m-2 canola-bean intercropping. In the intercropping parts only two species was observed while in the sole culture more than three species were exist. Results showed that with increasing in bean diversity, weed dry weight declines. According to our results, it is possible to control weed effectively by using intercropping system, but more studied is required. Diversity of weeds had been clearly affected. Results showed that only Beta and Malva species were existed in intercropping comparing to sole cultures that Brassica, Beta, Rumex and Malva were existed.
MicroRNA Implication in Cancer
Authors: BADIOLA Iker
Published: April 2018

MicroRNAs (miRNA) are a new class of posttranscriptional regulators. These small non-coding RNAs regulate the expression of target mRNA transcripts and are linked to several human disease such as Alzheimer, cancer or heart disease. But it has been the cancer disease which has experimented the major number of studies of miRNA linked to the disease progression. In the last years it has been reported the deregulation pattern of the miRNAs in malignant cells which have disrupted the control of the proliferation, differentiation or apoptosis. The evidence of the presence of specific miRNA deregulated in concrete cancer types has become the miRNAs like possible biomarkers and therapeutic targets. The specific miRNA patterns deregulated in concrete cancer cell types open new opportunities to the diagnosis and therapy.

The deposition of callose and the damage-related symptoms subsequently expressed by infested plants were investigated after feeding on barley leaves by bird cherry-oat aphid (BCA), Rhopalosiphum padi L. Feeding by this aphid does not result in appearance of visible damage to the plants, provided the feeding population is small. Using aniline blue fluorochrome, we confirmed that whilst low feeding density (5 aphids) results in appearance of wound callose in sieve tubes, this only occurs after 14d of feeding, when the feeding population had increased. Continued feeding results in progressively more callose deposition and by 21d, severe damage has been caused. In contrast, feeding by larger populations (50 adult aphids), results in the appearance of wound callose within 72h, in longitudinal and cross veins. We suggest that this wounding response appears to play a role in the appearance of golden yellow streak symptoms reported to occur in leaves where BCA feeding density was high.

Published: April 2018

Quorum sensing signals are referred to as acylated homoserine lactones (AHL) that are mainly found in Gram-negative bacteria. It implies the ability of certain bacteria of producing different AHL molecules. The bacteria Pseudomonas aureofaciens and Xenorhabdus nematophila were cultured in Luria-Bertani (LB10) media and CV026 was used as a reporter strain to detect the presence of AHLs produced by the cultured bacteria. In this study, the reporter strain has revealed the quorum sensing ability of P. aureofaciens and X. nematophila by producing the purple pigment violacein in the supply of external AHLs molecules. Thin layer chromatography (TLC) bioassay having four controls was conducted to detect specific AHL molecule supplied by P. aureofaciens and X. nematophila. The specific AHL molecule was observed to be migrated according to their polarity on the TLC plate.

In the present study, seeds from local cultivar of fennel were germinated on Murashige and Skoog medium (MS) without plant growth regulators. Different types of explants from the growing seedling such as cotyledonal leaves, hypocotyls, epicotyls and roots were cultured on MS medium, contained different concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D) either alone or with kinetin. Differential responses in the essential oil constituents were observed in the induction and development of callus. The major components of essential oils includes estragole, trans-anethole, limonene and fenchone were studied under different conditions to find out the best methods which could be used to reduce the amount of estragole (not favorite for human consumption) and increase the amount of trans-anethole.
Heterozygosity and Fixation Index for ABO Gene in Barak Valley Populations vis-a-vis a Few Exotic Populations
Authors: CHAKRABORTY Supriyo
Published: April 2018

In a genetic study of 26 human populations including 2 major endogamous populations (Hindus and Muslims) of Barak Valley in Assam and 24 exotic populations, observed heterozygosity (Ho), fixation index (F) and Panmictic index (P) for ABO gene were estimated from gene frequency data to reveal the extent of inbreeding that has taken place in each population during evolution. Observed heterozygosity, a measure of genetic variation, ranged from 0.3254 to 0.6086 in these populations. Expected Hardy-Weinberg heterozygosity of ABO gene was estimated as 0.6666 assuming the occurrence of all the three alleles in equal frequency. Fixation index was the highest in the population of Sudan (51.18%) followed by Australia (48.51%) and Iceland (38.28%) indicating the occurrence of high inbreeding and the presence of more homozygosity in these populations during evolution. But the fixation index was the lowest in the population of South China (8.70%) followed by Central Asia (11.82%) and Russia (12.96%). It suggested the occurrence of low inbreeding and hence more outbreeding in these populations resulting in the existence of more heterozygosity (high genetic variation) in these populations. Panmictic index, a measure of outbreeding, is the opposite of fixation index and it varied from 48.82 (Sudan) to 91.30% (South China). The population showing the highest fixation index recorded the lowest panmictic index and vice-versa. In evolutionary context, outbreeding in human populations would be more desirable to reduce the incidence of genetic diseases caused by recessive genes and to enhance heterozygosity for those loci for better adaptation of future generations, possibly at the cost of gradually increasing genetic load in the population.

In order to provide additional information on the effects of elemental deficiency on factors that affect plant production in medicinal plants, a factorial field experiment as randomized complete block design was conducted on Calendula officinalis. Treatments were four phosphorus levels (P2O5) including 0, 40, 80 and 120 Kg ha-1 and four potassium levels (K2O) as 0, 50, 100 and 150 Kg ha-1. Results showed that applied treatments had significant effects on petal carotenoids and the highest amount of ? - carotene obtained at 80 and 150 Kg ha-1 P2O5 and K2O, respectively. Effect of K2O on light interception and light use efficiency was significant and the highest radiation use efficiency achieved by applying 150 Kg ha-1 K2O. The highest yield of grain and dry flowers was recorded in the mixture of 80 and 150 Kg ha-1 P2O5 and K2O, respectively. In conclusion, using of K2O had greater effects on studied traits than P2O5.
