Published: January 2018

The inhibitory effect of indigenous Pseudomonas strains on Fusarium spp.
isolated from seeds of a new variety of carrot - ?Vizija? and their effects
on seed germination were observed. Pseudomonas spp. strains were applied as
bacterial suspensions (culture, 106 CFU mL-1) and cell-free supernatant (CFSa
-106 and CFSb -108 CFU mL-1) fractions by sowing seeds during 7 (I) and 14
(II) days of incubation. The germination of control ?Vizija? seeds was 19%
after the first and 40% after the second incubation period. Pseudomonas
chlororaphis Q16 strain exhibited statistically significant increases in seed
germination with all applied fractions and incubation periods, showing values
of 43-62% and 55.5-91%, i.e. increments of 24-43% and 15.5-51% compared to
the control, after 7 and 14 days of incubation, respectively. P. chlororaphis
K35 showed lower but significantly different seed germination values (38-67%)
for all variants, except for 7 days old culture. Pseudomonas sp. Ek1 had
weaker seed germination potential, showing statistically significant
increment only for CFSa,b (I) and CFSb (II) fractions. All tested Pseudomonas
strains inhibited the growth of three Fusarium species isolated from ?Vizija?
seeds: F. solani, F. oxysporum and F. subglutinans. Natural infection was
observed in 20% (I) and 54% (II) of ?Vizija? seeds. P. chlororaphis K35 was
the most efficient antifungal strain, reducing seed infection 97.5-100%,
followed by Q16 with 95-100%, showing no statistically significant mutual
difference. Pseudomonas sp. Ek1 showed a weaker antifungal activity and
reduced seed infection by 85-96.75%. The application of P. chlororaphis Q16
and K35 as strains effective in improvement of carrot seed germination and
growth inhibition of the seed pathogens F. solani, F. oxysporum and F.
subglutinans, can be further tested in carrot production for more beneficial
effects.

Authors: Gajic-Umiljendic Jelena , Saric-Krsmanovic Marija , Santric Ljiljana , Radivojevic Ljiljana
Published: January 2018

A laboratory bioassay was conducted to investigate common milkweed response
to sulcotrione. Sulcotrione was applied in concentration series of 0.15-0.90
kg a.i./ha without a surfactant and with Dash? at 1 L/ha. Plants grew for 14
days, upon which period morphological (height and fresh weight) and
physiological parameters (content of carotenoids, chlorophyll a and
chlorophyll b) were measured. Visual crop injury was estimated 7 and 14 days
after treatment. Sulcotrione caused leaf bleaching and reduction in pigments
content in common milkweed leaves and the degree of change depended on
application rates and whether it was applied with or without the surfactant.
Inhibition was slightly higher in plants which were treated with a
combination of herbicide and surfactant. Based on the findings in this study,
common milkweed showed moderate susceptibility to the recommended field rates
of sulcotrione.

Published: January 2018

The effects of copper citrate on defoliation of one year old fruit stocks in
a nursery are presented in this paper. The investigation aimed to evaluate
the defoliation efficacy of copper citrate as a new formulation, compared
with other compounds recommended for that purpose. Field trials were
conducted in the region of Trstenik, a center of nursery production in Serbia
in 2016 and 2017. Two years of investigation showed that copper citrate could
be used as an efficient compound for defoliation in nursery production. A
stronger defoliation effect was observed on plum stocks, compared to apple
stocks. Better results were achieved with the highest concentration of copper
citrate (2%), while the effectiveness decreased with lower concentrations
(0.5%, 1.0% and 1.5%). Defoliation degree on nursery apple stocks after
treatment with 2.0% concentration of copper citrate varied from 80.6% to
95.6%, while it reached 100% on plum stocks.
Connective action as the new pattern of protest activism
Authors: Petrovic Jelisaveta , Petrovic Dalibor
Published: January 2018

The aim of this paper is to examine the organizational background of the
protests ?Against dictatorship? that took place in several Serbian towns, in
the spring of 2017. The absence of the official organizers and the role
social networking sites played in terms of communication, organization and
coordination of the protest events, raises the following question: Could the
protest ?Against dictatorship? be considered as an example of a digitally
enabled ?connective? action? According to the ?connective action? approach
(Bennett & Segerberg, 2012, 2013), in the information society a new
?connective? form of collective action is emerging as a result of
personalization of political action that occurs within new sociotechnological
environment. Connective action is enabled by innovative technological
opportunities for individual participation in collective ventures and
supported by the role that ICTs play as ?stitching? and organizing agents of
collective action. In such circumstances, conventional social movement
organizations and solid collective identities seem to become far less
necessary. The analysis of the data collected in the field (N = 175) and in
the online survey of the experiences and attitudes towards the protest
(N=225), leads to the conclusion that the organizational background of the
protest ?Against dictatorship? is closest to the ideal-type of
?self-organized network?, as one of the two basic models of connective
action. In the concluding part of this paper, the authors argue that the
?connective action? model is adequate for the interpretation of the emergence
of the digitally mediated protests. However, with the transformation of
protests into more solid and stable forms of collective action, this model
loses its explanatory power.
Political participation of the participants in the protests against dictatorship
Authors: Pesic Jelena
Published: January 2018

The aim of this paper is to determine the extent to which participants in the
Protests against Dictatorship were ready to engage in various forms of
collective action over the past three years. In accordance with Pippa Norris?
division of the repertoire of actions on those oriented towards the problems
of citizens and directed towards decision-makers in the political sphere and
repertoires oriented towards the broader social goals, and with corresponding
distinction between the traditional and modern agencies of collective
actions, we tried to test the hypothesis that participants in the Protests
against Dictatorship show a relatively high degree of readiness to engage in
both traditional and contemporary forms of collective engagement. In
addition, we tried to examine the claim that contemporary repertoires of
collective actions will be more strongly represented among the younger
population, as well as the thesis that the level of engagement will be in a
positive relation with the resources that participants in the protest posses
(educational, material, organizational, social, etc.). Finally, we tested the
hypothesis that readiness to participate in civic and political actions is
growing with a degree of trust in the institutions of representative
democracy, but also with an assessment of the importance of a democratic
political order. The hypotheses were tested on empirical data obtained
through a survey of protest participants conducted during April and May 2017.

Authors: Grippaudo Cristina , Cafiero Concetta , D'Apolito Isabella , Ricci Beatrice , Frazier-Bowers Sylvia A.
Published: January 2018

Objective:

To test the hypothesis that mutations in the parathyroid hormone 1 receptor (PTH1R) include effects in both primary and permanent teeth.

Materials and Methods:

DNA was extracted from saliva samples of 29 patients (8 familial and 21 sporadic) who presented with clinical evidence of infraoccluded teeth, and their unaffected relatives (N = 22). Sequencing followed by mutational analysis of the coding regions of PTH1R gene was completed for all individuals (N = 29).

Results:

Eight of 29 cases revealed a heterozygous pathogenic variant in the PTH1R gene; five of eight variants represented distinct mutations based on comparison with the dbSNP, HGMD, and ESP databases. One mutation (c.1765 T>C p.Trp89Arg) was found to segregate within a family (n = 3). In silico analyses for all variants revealed a putative pathogenic effect. A genotype-phenotype correlation was reported as defined by a functional mutation in PTH1R and corresponding effects on one or more posterior teeth only; unilateral or bilateral involvement, infraoccluded primary teeth.

Conclusions:

Novel mutations were reported in the PTH1R gene that included PFE-affected primary molars, thus providing the basis for using a genetic diagnostic tool for early diagnosis leading to proper management.

Published: January 2018

Objective:

To examine the changes in visual attention influenced by facial angles and smile during the evaluation of facial attractiveness.

Materials and Methods:

Thirty-three young adults were asked to rate the overall facial attractiveness (task 1 and 3) or to select the most attractive face (task 2) by looking at multiple panel stimuli consisting of 0°, 15°, 30°, 45°, 60°, and 90° rotated facial photos with or without a smile for three model face photos and a self-photo (self-face). Eye gaze and fixation time (FT) were monitored by the eye-tracking device during the performance. Participants were asked to fill out a subjective questionnaire asking, “Which face was primarily looked at when evaluating facial attractiveness?”

Results:

When rating the overall facial attractiveness (task 1) for model faces, FT was highest for the 0° face and lowest for the 90° face regardless of the smile (P < .01). However, when the most attractive face was to be selected (task 2), the FT of the 0° face decreased, while it significantly increased for the 45° face (P < .001). When facial attractiveness was evaluated with the simplified panels combined with facial angles and smile (task 3), the FT of the 0° smiling face was the highest (P < .01). While most participants reported that they looked mainly at the 0° smiling face when rating facial attractiveness, visual attention was broadly distributed within facial angles.

Conclusions:

Laterally rotated faces and presence of a smile highly influence visual attention during the evaluation of facial esthetics.

Published: January 2018

Dor abdominal aguda é uma das principais queixas pediátricas com vários diagnósticos diferenciais. Paciente de dois anos e oito meses, do sexo feminino, negra, natural de Itapeva, São Paulo. Referia dor abdominal, diarreia e tosse havia 16 dias. Foi internada com hipótese diagnóstica de pneumonia. Durante a internação apresentou tosse, gemência, desconforto respiratório, vômitos, diarreia, distensão abdominal e febre. A má evolução do quadro e a piora da dor abdominal levaram à realização de uma tomografia abdominal que revelou apendicolitos. Foi encaminhada ao serviço de referência, onde houve a suspeita de apendicite aguda e foi realizada intervenção cirúrgica. O diagnóstico conclusivo foi de apendicite aguda purulenta. A paciente evoluiu dentro do esperado e teve alta dez dias após a cirurgia. Numerosos distúrbios podem causar dor abdominal; as causas mais comuns são gastroenterite e apendicite; porém, outros diagnósticos diferenciais devem ser considerados, entre eles pneumonia. No caso relatado, apesar de a paciente estar inicialmente taquidispneica, apresentava dor abdominal intensa e desidratação. Uma boa anamnese é fundamental. As alterações laboratoriais são inespecíficas e ocorrerem nos dois casos. Diante de um quadro de pneumonia com má evolução, é importante pensar na possibilidade de outro diagnóstico, entre eles apendicite, se o quadro vier acompanhado de dor abdominal, devido à sua alta morbimortalidade.

Published: January 2018

This paper deals with a study of the physical and mechanical characteristics of volcanic tuff and ignimbrite from six quarries located at different areas in the western part of Yemen (Manakha, Jahran, Bakhran, Dar Al-Hanash, Abaser and Soraifa). In the region, volcanic tuffs and ignimbrite are locally known by their location names and have been used as solid masonry and cladding stones. All the investigated pyroclastic rocks belong to the Tertiary volcanic. The standard physical and mechanical tests (void ratio, porosity, density, specific gravity, water absorption, uniaxial compressive strength and tensile strength) were carried out on the tuff and ignimbrite samples collected from different parts of the region. Laboratory tests revealed that the void ratio average values range between 0.12 and 0.37, the porosity ranges between 10.57 and 27.12%, the dry density ranges between 1.66 and 2.25 gm/cm3, specific gravity ranges from 1.45 to 1.94, and water absorption ranges from 4.69 to 16.39%. The measured uniaxial compressive strength values range from 24 to 68 MPa, and the tensile strength values range between 4 and 10 MPa. These tuffs and ignimbrites generally are light green, gray, beige, or yellowish in color. With these colors they are favoured for building, coating and decorative stone. This paper concludes that the studied stones have acceptable to good properties as dimension stone. Jahrani and Manakhi tuffs are the best quality, whereas Hanashi ignimbrite is of poorer quality.

Adivinhação, superstição e religião no último século da República (Cícero e Lucrécio)
Authors: Novak Maria da Gloria
Published: January 2018

Confundem-se religião e superstição no último século da República e a religião é poderosa arma nas mãos dos poderosos. O homem se sente fraco e imagina forças sobrenaturais que o protejam, tendência que o estoicismo reforça e o epicurismo combate. Assim, adivinhação e epicurismo são absolutamente incompatíveis. Lucrécio, materialista e coerente, clama contra todas as formas de superstição e contra o comportamento absoluto que dela deriva. Cícero (que tão veementemente critica a adivinhação) defende-a e defende também a religião oficial, porque sabe que só esta pode manter o homem livremente submisso ao Estado.
Ghost Dark Energy Model with Non-linear Interaction
Authors: REVISTAS SISTEMAS , Oliveros Garcia Alexander
Published: January 2018

In this paper we study a dark energy model taking into account a non-linear interaction between the dark energy and dark matter components. The non-linear interaction term, used in this work, is proportional to the square of dark energy density. Considering a FRW type ﬂat universe, we obtain an analytical expression for the Hubble parameter H and from this quantity, the deceleration parameter q and the equation of state parameter w Λ are analyzed. We found that, in this scenario, the accelerated expansion regime of the universe in late times is possible. However, using suitable values for the coupling constant, the square of the speed of sound remains negative, therefore, the model is unstable under small perturbations.

Published: January 2018

Polysaccharides (PS) from wheat cell culture were isolated by liquid-liquid extraction. The molecular mass distribution was determined by gel-permeation chromatography (GPC) using dual detectors for the simultaneous detection. It was supposed that PS sample from wheat cell culture has molecular weight of 1632 Da. The physic-chemical properties of PS such as solubility in different solvents, surface activity, ξ-potential, the pH value, polydispersity (PDI) were determined. The PS sample was soluble in water and insoluble in ethanol, acetone and chloroform. ξ-potential of PS was evaluated in order to determine its charge at different pH value from 3 to 9. As a result, the ξ values for the PS solution were negative throughout the pH range studied, varying from -2.85 mV (pH 3.0) to -21.1 (pH 9). Using tensiometry method, surface tension of the PS at the liquid/air interface was investigated. At 0.05% concentration interfacial tension decreases slowly and reaches an equilibrium value after ~ 8-8.5 hours. The pH was equal to 5.6±0.05. For a PS solution of 0.001% at pH 5.5 PDI was equal to 0.595.

Published: January 2018

Heavy metals uptake, distribution and accumulation processes in plants are very important for their impact on physiological and biochemical processes and, consequently, on plant growth and development. The distribution of heavy metals in plant parts and cell organelles are discussed. There are detoxification mechanisms in cell compartments, like binding with cell wall, with organic acids in vacuoles, complexes with phytochelatins and etc. What proportion of given metal ions would be the in free form, and what – bound with organic molecules; it depends from pH of the environment and chemical properties of element. The stability of metals complexes decreases in the case of deviation pH of environment from neutral: at low pH there is a competition of protons with metal ions for binding sites in molecules, at high pH – by the reason of the competition of hydroxyl groups with ligand.

The problem of obtaining safe foodstuff has remained relevant for a very long time. Long period of soil self-purification and the expensiveness of its artificial treatment forced mankind to look for new ways to solve problems related to soil pollution with heavy metals. The most perspective direction in this field is the identification of plant facilities, characterized by minimal accumulation of heavy metals. The purpose of our research is to identify wheat germplasm, resistant to heavy metals (zinc, cadmium) primarily in Eastern Kazakhstan, and discover donors for selection for metal resistance and perspective wheat forms, intended to implement into production. The research subject is various genotypes of spring wheat from the collection of Eastern Kazakhstan Agricultural Scientific Research Institute. The experiments were held in condition of modeling environmental pollution on 10-day-old sprouts of different wheat genotypes, grown on nutrient mixture, containing CaSO4 0.1mm and Cd ions at a concentration of 40 mg/L (as CdSO4 salt) or Zn at a concentration of 400 mg/L (as salt ZnSO4). Since a direct negative impact of heavy metals on plants is displayed in inhibiting of their growth and development (root and sprout growth weakening), indicators of wheat genotypes growth processes were examined during the experiment and Wilkins coefficient was defined. The study revealed sensitive and metal resistant samples. Studies of membrane permeability for electrolytes interms of environmental pollution by cadmium and zinc, have led to the conclusion that plant resistance can generally be caused by cell membranes’ resistance to the action of the stressor. Membrane permeability for electrolytes in the most resistant wheat variety Altai changed less comparing to a more sensitive variety of spring wheat Erythrospermum-606 during the action of both cadmium and zinc. This fact proves that the overall resistance of plants may be due to stability of cell membrane to the action of the stressor.

Seeds of the spring bread wheat variety Zhenis, registered in Kazakhstan, were irradiated with 100 and 200 Gray doses from a [60Co] γ-ray radiation source. Promising advanced M5 mutant lines were obtained and evaluated for mapping density of vernalization requirement associated dominant VRN-A1 gene and earliness related Esp-A1 candidate genes in 30 spring wheat mutant lines along with parent. Differences among generated mutant lines and parent were observed on frequency of distribution of VRN-A1 gene and Eps-A1 candidate gene alleles. Allelic variation at the VRN-A1 loci was observed in the 8 mutant lines (26.6%), mostly in 100 Gy mutant lines. A dominant (VRN) allele at its loci, which was present and indicated in these lines is sufficient to confer a spring growth habit. As for the candidate gene Esp-A1, eleven 100 Gy M5 mutant and six 200 Gy M5 lines, had Esp-A1 candidate gene allele. The two lines24(2) and 43(4) carrying dominant allele of VRN-A1 had higher thousand kernel weight. Mutant lines carrying allele of Eps-A1 candidate gene found significantly differed from the parent especially in 100 Gy lines (73.3%) in flowering time.

This work presents results on behavioral reactions and sensitivity of molluscs and fish to experimental modelling of accidental oil pollution during the first 72 hours. It is shown that mobile hydrobionts, such as fish attempt to escape the contaminated area during the first 24 hours after the oil spill. Benthic animals – molluscs are more susceptibleto pollution, they almost instantly lose their mobility, become inert and try to escape their shells further on, which serves as an evidence of death throes. Light crude with high content of paraffin was used for the present experiment.

Published: January 2018

Plural society built by the prophet was a reflection of an ideal society that can live together as the result of the application of a persuasive communication. A plural society is a society that is composed of various groups, races, tribes, nations, and others. Their existence should get a proper guidance so that people could possess certain qualities such as loving the good deeds and against the bad deeds and violence as Islam instructs. Universal Islamic values govern relations based on mutual respect, non-coercion, justice, humanity, togetherness, and brotherhood. Islam as a social religion strongly supports the effort to establish the relationship of human dignity as a whole. For that, it seems necessary to have a persuasive communication that can touch the psychological aspects of various societies. This method will be easier to bring about an effective result that is the commitment of each group on faith and humanity with the boundaries of rights and obligations. Such situation can foster motivation and confidence to achieve unity and the welfare of the people, which in turn they can live in tolerance, justice, togetherness, brotherhood, and many others.

Radiasi Benda Hitam dan Efek Fotolistrik Sebagai Konsep Kunci Revolusi Saintifik dalam Perkembangan Teori Kuantum Cahaya
Authors: Sutarno Sutarno , Erwin Erwin , Hayat Muhammad Syaipul
Published: January 2018

Teori fisika klasik telah menghasilkan konsensus bahwa cahaya merupakan gelombang elektromagnetik yang terdistribusi secara malar dalam ruang tiga dimensi. Cahaya merambat transversal dengan laju energi sebanding dengan intensitasnya. Paradigma ini telah menuntun rangkaian aktivitas ilmiah pada sains normal yang menghasilkan berbagai perkembangan ilmu pengetahuan. Teori gelombang elektromagnetik terus berkembang hingga awal abad 19 sebelum akhirnya gagal menjelaskan fakta spektrum radiasi benda hitam dan efek fotolistrik. Teori fisika klasik mengalami krisis. Fase ini mendorong para ilmuwan melakukan berbagai spekulasi teori dan eksperimen guna memperoleh penyelesaian masalah. Muncul pemikiran revolusioner yang diilhami oleh gagasan Planck yang selanjutnya diartikan lebih fisis oleh Einstein membentuk teori kuantum cahaya. Fenomena radiasi benda hitam dan efek fotolistrik dapat dijelaskan secara memuaskan hanya dengan menganggap bahwa cahaya tidak terdistribusi secara malar, melainkan dalam bentuk paket-paket energi yang disebut kuanta (foton). Besar energi foton tidak ditentukan oleh intensitas, melainkan oleh frekuensi cahaya. Fenomena radiasi benda hitam dan efek fotolistrik telah membuka gerbang pergeseran paradigma, dari fisika klasik menuju fisika modern.
