In this study, resistance mechanism of two wheat genotypes against salt, heavy metal, lime and drought (50%) treatments were investigated in summer Cumhuriyet-75 and winter Selimiye-95. According to results chlorophyll a, b, total chlorophyll and carotenoid level increased in FeCl3, drought and 225 mM NaCl in Cumhuriyet-75 but they were higher at NaCl, FeCl3 and ZnCl2 treatments in Selimiye-95 comparison to control. While H2O2 content rose all stres treatments in both varieties but Malondialdehyde (MDA) decreased in Selimiye with all applications. The amount of proline is lower in Cumhuiyet-75 but higher in Selimiye-95. Total soluble protein was found higher at salt concentartion and drought in both varieties. Ascorbate peroxidase (APX), Süperoxide dismutase (SOD) activity increased in salt and FeCl3 in Selimiye-95 but SOD ativity were higher at salt treatments in Cumhuriyet-75. And also in both varieties APX and Guaiacol peroxidase (GuPX) increased at FeCl3 but Catalase (CAT) were higher in only FeCl3 in Cumhuriyet-75. As a result Selimiye-95 showed tolerance to salt and FeCl3 with high photosynthetic pigment, proline and soluble protein content with lower MDA but it is sensitive to NiCl2 and drought. Whereas Cumhuriyet-75 cultivar is resistan to drought, FeCl3 and 225 mM NaCl depended on pigment, protein content and APX, CAT, GuPX and SOD activities. When all the data are taken into consideration, it was concluded that the responses of the varieties to the treatments changed according to the type and concentration of stress, and Selimiye-95 variety was tolerant compared to Cumhuriyet-75 variety.

A SEGURIDADE SOCIAL NO BRASIL E A EQUIPARAÇÃO ETÁRIA ENTRE OS GÊNEROS PARA A APOSENTAÇÃO: UMA AVALIAÇÃO CRÍTICA DA PROPOSTA DE EMENDA CONSTITUCIONAL 287/2016
Authors: Silva Juvêncio Borges , Barbosa Kelly De Souza
Published: July 2018

O presente artigo tem como objetivo a discussão da Proposta de Emenda Constitucional 287/2016, denominada de PEC da Reforma Previdenciária, no que se refere à equiparação etária entre homens e mulheres para que tenham o direito à aposentadoria. Analisa o sistema de seguridade social e os fundamentos sociais e jurídicos da diferenciação etária entre homens e mulheres para a aposentação. Faz a seguir uma avaliação crítica da Proposta de Emenda Constitucional 287/2016 no que se refere à equiparação de idade entre homens e mulheres para aposentação, referenciando-se pela teoria da justiça como reconhecimento de Nancy Fraser, para concluir que o critério puramente isonômico de idade não é razoável para justificar a equiparação etária de gênero para a aposentação no Brasil, fazendo-se necessário considerações de natureza cultural (justiça como reconhecimento), que apontam para a necessidade de manutenção da diferença de idade para a aposentação entre homens e mulheres, respeitando, assim, as diferenças naturais, sociais e culturais entre os gêneros. A pesquisa orientou-se pela método analítico-dedutivo, lastreado em pesquisa bibliográfica, legal, jurisprudencial e documental.

Authors: Cavalcante Denise Lucena , Pereira Fabrícia Helena Linhares Coelho da Silva , Sousa Thanderson Pereira de
Published: July 2018

O novo regime fiscal trouxe uma limitação para gastos públicos primários no Brasil, abrangendo o financiamento do Sistema Único de Saúde, a partir de 2018. Essa limitação orçamentária não atingiu, por outro lado, as deduções tributárias que findam por fortalecer o setor privado de saúde. Nesse contexto, analisa-se os impactos do novo regime fiscal em face do gasto em saúde. A metodologia utilizada é predominantemente qualitativa, servindo-se de técnicas bibliográfica e documental, contando também com a análise quantitativa dos orçamentos da União Federal. Constata-se que a restituição de valores do Imposto de Renda – IR e os incentivos às instituições filantrópicas com base nos serviços de saúde aperfeiçoam o sistema privado de saúde e funciona como um gasto no que diz respeito à atividade financeira do Estado, embora não sejam restringidos pelo novo regime fiscal. O risco de redução no financiamento da saúde pública, diante da limitação de gastos primários, não seria concebível em um sistema de saúde universal, como o brasileiro, especialmente quando os gastos públicos com o setor privado de saúde representam recursos que seriam importantes para o estímulo ao SUS.

Las redes sociales, como Facebook, son herramientas útiles para el comercio, por lo que la venta ilegal de animales y plantas, siendo el tercer mayor comercio ilegal del mundo, está aprovechando este nuevo mecanismo para la compraventa y distribución ilegal de especies amenazadas, en peligro de extinción o sin procedencia legal, en el estado de Tamaulipas, con una ventaja considerable, la de no poder iniciar un proceso legal in situ. El objetivo del presente estudio fue determinar el uso activo de Facebook como factor criminógeno en la compra y venta de flora y fauna enlistadas en categorías de riesgo o que no hayan sido adquiridas de manera legal y sostenible, de acuerdo a la NOM-059-SEMARNAT-2010, en Tamaulipas, México. Se realizó la búsqueda digital de las páginas de Facebook que se dedican a la venta de especies en la zona sur, centro y norte del estado, durante el periodo de enero a noviembre 2016. Mediante un método mixto de carácter retrospectivo, se analizó la venta ilegal de especies, como parte de la criminodinámica de una conducta antisocial que contraviene el patrimonio colectivo y el bien común. Se encontró que se movieron $ 176 260 del comercio ilegal en esta red en el periodo estudiado: la zona norte con un 96 % de la participación económica, seguida por la zona sur con un 3 %, y por último la zona centro, con el 1 %. La utilización de la perspectiva criminológica permitió establecer la criminodinámica existente en el comercio ilegal de especies, a través de las redes sociales. Este conocimiento puede servir a las autoridades correspondientes para fincar responsabilidades legales a los participantes, así como para impartir educación ambiental y orientación a la población, para no verse involucrado en  delitos  del  fuero  común  y  federal.

Published: July 2018

Mineral deposits (among which non-ferrous metals take a leading place) are situated on the territory of our planet rather unevenly, and often in out-of-the-way places. Nuclear power (particularly, transportable nuclear power plants) provides the new possibilities of power supply, which is very important for deposits' development. This article shares the economic aspects of forecasting in the field of power development (in particular, nuclear power on the basis of transportable nuclear power plants). Economic barriers of development of innovative nuclear technologies are considered on the example of transportable nuclear power plants. At the same time, there are given the ways of elimination of such barrier to development of this technology as methodical absence of investigation of a question of distribution of added cost between producers of innovative equipment and final product. Addition of new analytical tool (“business diagonal”) is offered for a method of definition of economically efficient distribution of added cost (received as a result of introduction of innovative technologies) between participants of production and consumption of atomic energy within the “economic cross” model. There is offered the order of use of method of cash flows discounting at calculations between nuclear market participants. Economic methods, offered in this article, may be used in forecasting of development of other energy technologies and introduction of prospective energy equipment.

Cryogenic heat treatment — a review of the current state
Authors: Amini Kamran , Akhbarizadeh Amin , Javadpour Sirus
Published: July 2018

The deep cryogenic heat treatment is an old and effective heat treatment, performed on steels and cast irons to improve the wear resistance and hardness. This process includes cooling down to the liquid nitrogen temperature, holding the samples at that temperature and heating at the room temperature. The benefits of this process are significant on the ferrous materials, but recently some studies focused on other nonferrous materials. This study attempts to clarify the different behavior of some materials subjected to the deep cryogenic heat treatment, as well as explaining the common theories about the effect of the cryogenic heat treatment on these materials. Results showed that polymers exhibit different behavior regarding to their crystallinity, however the magnesium alloys, titanium alloys and tungsten carbide show a noticeable improvement after the deep cryogenic heat treatment due to their crystal structure.

Considering possible applications and scarceness of literature data, Ag-Bi-In system was investigated in terms of microstructure, mechanical and electrical properties of ternary alloys from an isothermal section at 100oC. Based on the experimentally obtained results hardness and electrical conductivity of all ternary alloys from the ternary Ag-Bi-In system at 100oC were predicted. In addition, the selected isothermal section was further thermodynamically assessed and experimentally studied using scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), X-ray powder diffraction (XRD) analysis and light optical microscopy (LOM). Phase transition temperatures of alloys with overall compositions along vertical sections x(Ag)=0.5 as well as liquidus temperatures were experimentally determined by DTA. The experimentally obtained results were compared with literature data and with the results of thermodynamic calculation of phase equilibria based on CALPHAD method and corrected data for Ag-In binary system. Calculated liquidus projection, invariant equilibria and phase diagram of the Ag-Bi-In ternary system are presented as well.

Published: July 2018

Acacia tortilis (AT) was extracted and characterized by gas chromatography-mass spectrometry (GC-MS). The eco-friendly corrosion inhibitor for aluminum matrix composites was investigated in 1.0 M HCl at 30-60 °C. The concentration of the inhibitor and time were varied in the range of 0 – 10 % v/v and 24-144 h. The inhibition studies were carried out using gravimetric method and potentiodynamic polarization. The surface morphology of the coupons was characterized by SEM/EDS techniques. The GC-MS revealed some elements/compounds (NCS, C-H, N or O). The inhibition efficiency increased with concentration and decreased with increase in temperature. The optimum inhibition efficiency of 89.60% was obtained at concentration of 8% v/v at 30 °C. Potentiodynamic polarization confirmed that the inhibitor acts as mixed types inhibitor. Activation energy (Ea) with inhibitor was higher than without inhibitor and proved to be physisorption. The thermodynamic parameters (standard free energy ΔG°), standard enthalpy (ΔHads) and standard entropy (ΔS) of the adsorption process were calculated. The inhibition mechanism of AT extract on Al-Si-Fe/15%SiC was physical and obeyed Langmuir adsorption isotherm. The protective layer on the composite surface confirmed the potential of the extract as corrosion inhibitor. The results of weight loss were in good agreement with those of electrochemical technique.

Authors: Davari Mohammad , Mansouri Hasan Abadi Mehdi
Published: July 2018

In the present study, the effect of intercritical heat treatment temperature on the tensile properties and work hardening behavior of ferritic-martensitic dual-phase steel have been investigated utilizing tensile test, microhardness measurement and microscopic observation. Plain carbon steel sheet with a thickness of 2 mm was heat treated at 760, 780, 800, 820 and 840 °C intercritical temperatures. The results showed that martensite volume fraction (Vm) increases from 32 to 81%with increasing temperature from 760 to 840 °C. The mechanical properties of samples were examined by tensile and microhardness tests. The results revealed that yield strength was increased linearly with the increase in Vm, but the ultimate strength was increased up to 55% Vm and then decreased afterward. Analyzing the work hardening behavior in term of Hollomon equation showed that in samples with less than 55% Vm, the work hardening took place in one stage and the work hardening exponent increased with increasing Vm. More than one stage was observed in the work hardening behavior when Vm was increased. The results of microhardness test showed that microhardness of the martensite is decreased by increase in heat treatment temperature while the ferrite microhardness is nearly constant for all heat-treated samples.
Reaction mechanism and kinetics of sulfide copper concentrate oxidation at elevated temperatures
Authors: Mitovski Aleksandra , Štrbac Nada , Sokić Miroslav , Kragović Milan , Grekulović Vesna
Published: July 2018

Sulfide copper concentrate from domestic ore deposit (Bor, Serbia) was subjected to oxidation in the air atmosphere due to a better understanding of reaction mechanism and oxidation of various sulfides present in the copper concentrate at elevated temperatures. Results of the initial sample characterization showed that concentrate is chalcopyrite–enargite-tennantite type, with an increased arsenic content. Characterization of the oxidation products showed the presence of sulfates, oxysulfates, and oxides. Based on predominance area diagrams for Me-S-O systems (Me = Cu, Fe, As) combined with thermal analysis results, the reaction mechanism of the oxidation process was proposed. The reactions which occur in the temperature range 25 – 1000 °C indicate that sulfides are unstable in the oxidative conditions. Sulfides from the initial sample decomposed into binary copper and iron sulfides and volatile arsenic oxides at lower temperatures. Further heating led to oxidation of sulfides into iron oxides and copper sulfates and oxysulfates. At higher temperatures sulfates and oxysulfates decomposed into oxides. Kinetic analysis of the oxidation process was done using Ozawa’s method in the non-isothermal conditions. The values for activation energies showed that the reactions are chemically controlled and the temperature is the most influential parameter on the reaction rates.

Published: July 2018

The assessment of Psidium guajava leaf extract as corrosion inhibitor for Al-Si- Mg (SSM-HPDC) alloy in 3.5%wt NaCl solution using the gravimetric based-mass loss and potentiodynamic polarization techniques was investigated. The gravimetric based mass loss test was carried out at different inhibitor concentration, time and temperature ranges of 0.1-0.5%v/v, 1-5 hrs and 30-70oC, respectively, the results revealed that Psidium guajava leaf extract in 3.5%wt NaCl solution-aluminium environment decreased the corrosion rate at various concentrations considered. Inhibition efficiency (IE) as high as 63.17% at 0.5% v/v Psidium guajava leaf extract addition using the gravimetric method was demonstrated in 3.5%wt NaCl solution. The IE of 90.48% was obtained at 0.5%v/v using the potentiodynamic polarization method. The additions of Psidium guajava leaf extract as corrosion inhibitor in the solution indicate higher potential value, IE and polarization resistance with decrease in current density. The two methods used for assessment of the aluminium alloy corrosion behaviour were in agreement and mixed-type corrosion exists which obeyed the Langmuir adsorption isotherm.

Authors: Dehnavi Mehdi , Haddad-Sabzevar Mohsen , Avazkonnadeh-Gharavol Mohamad Hasan
Published: July 2018

The Al-Cu alloys have been widely used in aerospace, automobile, and airplane applications. Generally Al–Ti and Al–Ti–B master alloys are added to the aluminium alloys for grain refinement. The cooling curve analysis (CCA) has been used extensively in metal casting industry to predict microstructure constituents, grain refinement and to calculate the latent heat of solidification. The aim of this study is to investigate the effect of cooling rate and grain refinement on the thermal and thermodynamic characteristics of Al-Cu alloys by cooling curve analysis. To do this, Al-Cu alloys containing 3.7, and 4.8 wt.% Cu were melted and solidified with 0.04, 0.19, 0.42, and 1.08 K/s cooling rates. The temperature of the samples was recorded using a K thermocouple and a data acquisition system connected to a PC. Some samples were Grain refined by Al-5Ti-1B to see the effect of grain refinement on the aforementioned properties. The results show that, in a well refined alloy, nucleation will occur in a shorter time, and a undercooling approximately decreases to zero. The other results show that, with considering the cooling rate being around 0.1 °C/s, the Newtonian method is efficient in calculating the latent heat of solidification.

From Tinkering to Going “Rogue”: How Principals Use Agency When Enacting New Teacher Evaluation Systems
Authors: Donaldson Morgaen L. , Woulfin Sarah
Published: July 2018

Despite major changes to teacher evaluation since 2009, scant research examines how principals enact these policies. Drawing on qualitative interviews with 44 principals in 13 Connecticut districts, we use structure-agency theory to characterize how principals improvised when implementing the state evaluation model. We find that principals’ use of discretion varied across the system’s components, took different forms, and appeared aimed at varied outcomes. Particular forms of discretion supported the system’s goals, while others likely undermined them. Principals tended to use their discretion to further the system’s development aims as opposed to its accountability goals. Our findings have implications for the enactment of teacher evaluation policy, the roles of district administrators, and principals’ work as instructional leaders in an accountability context.

Jacopo Berengario da Carpi was an Italian physician.
He wrote many books on anatomy and surgery. In this study, Jacopo Berengario da Carpi’s books and
his contributions to neuroanatomy was researched. Berengario
described vermiform appendix, arytenoid cartilage, thymus, seminal vesicle,
sphenoid sinus, pineal gland, choroid plexus, tympanic membrane, auditory
ossicles and he explained in detail the cardiac valves, pancreas and kidneys.
Berengario clearly
identified to the differences in the dimension of the chest and pelvis between
males and females. Additionally, he described the vertebral column, spinal
nerves, recurrent laryngeal nerve and ventricles of the brain. He depicted many
anatomical structures with an artistic point of view in his drawings. It is
also seen that, he mentioned on knowledge of previous physicians and made
comments on this knowledge in his books.

Jacopo Berengario
da Carpi should be
appreciated because of his valuable scientific contributions.
Почвенные грибы как компоненты постагрогенных биогеоценозов в тундре
Authors: Ковалева В. А. , Денева С. В. , Панюков А. Н. , Лаптева Е. М.
Published: July 2018

Изучены количественные показатели и качественные характеристики микобиоты в почвахзонального биогеоценоза и разновозрастных постагрогенных экосистем в подзоне южной кустарниковой тундры (Воркутинский район, Республика Коми). Исследования микробной биомассы в почвах свидетельствует о доминировании в ней грибов. Для почвы 14-летней постагрогенной экосистемы характерны более высокие показатели длины и биомассы мицелия в отличие от почв ерниково-ивняковой моховой тундры и почвы 46-летней постагрогенной экосистемы, где на долю спор приходится до 40% всей грибной биомассы. Комплекс микромицетов исследованных почв представлен 34 видами из 11 родов отделов Zygomycota и Ascomycota. Микобиота всех рассмотренных почв характеризуется обилием стерильного мицелия, преобладанием видов рода Penicillium, постоянным присутствием вида Geomyces pannorum. Наибольшим видовым разнообразием отличается близкий к климаксному микоценоз почвы 46-летней постагрогенной экосистемы, что отражает классическую схему постагрогеннойсукцессии почвенных микробоценозов. Отличия в видовом составе растительных сообществ зональной экосистемы и 14-летней постагрогенной экосистемы обусловливают специфичность почвенной микобиоты последней.
Мета-анализ влияния рубки хвойных лесов и последующих сукцессионных изменений на численность почвенных нематод
Authors: Кудрин А. А.
Published: July 2018

Проведен мета-анализ влияния рубки хвойных лесов на численность нематод. Показано,что наиболее ярко эффект сведения древесной растительности в результате промышленной рубки хвойных лесов проявляется на начальных этапах восстановительной сукцессии (0-5 лет) и выражается в значительном сокращении численности нематод в почвах по сравнению с контрольными, ненарушенными, биотопами. На 8-11-й год сукцессионной смены растительности величина эффекта приближается к нулю. Мета-анализ показал, что более выраженное отрицательное влияние на почвенных нематод оказывает удаление порубочных остатков на лесосеках после рубки древостоя. При их сохранении на поверхности почвы численность нематод близка к контрольным участкам. Величина отрицательного эффекта рубки может зависеть и от вида деревьев-эдификаторов. Сокращение численности нематод в почвах послерубочных экосистем более ярко проявляется в сосновых лесах. В ельниках и лесах, основу древостоя которых составляют псевдотсуга и туя, негативный эффект рубки выражен слабее, чем в сосняках, и не отличается между собой.
Istup člana društva s ograničenom odgovornošću
Authors: Brnabić Ratko , Brkić Bojan
Published: July 2018

Istup člana iz društva je pravno sredstvo koje je zakonodavac stavio na raspolaganje članovima društva s ograničenom odgovornošću, a riječ je o dobrovoljnom izlasku iz društva što za posljedicu ima prestanak članstva. Tim sredstvom oni se ne mogu koristiti bez ograničenja. Naime, istupom člana mijenjaju se članski odnosi u društvu, a društvo je članu dužno isplatiti i naknadu za njegov poslovni udio što može utjecati na sposobnost društva za podmirivanje svojih obveza. Stoga se istup može dopustiti samo pod pretpostavkama uređenima Zakonom, u suprotnom bi pravo na istup predstavljalo sredstvo zlouporabe prava. U tom smislu, posebnu pozornost pobuđuje pojam opravdanog razloga za istup člana i njegov sadržaj treba utvrditi i izvan okvira zakonske odredbe koja ga uređuje. Članovi mogu svojim pravima raspolagati i na drugi način pa tako mogu svoje poslovne udjele u društvu prenijeti na treće. U praksi se, međutim, pokazalo da se u društvene ugovore nerijetko unose odredbe o vinkulaciji poslovnih udjela pa je tada potrebno za prijenos dobiti odobrenje društva. Nadalje, kod poduzetničkih ugovora, kod priključenja kao i kod statusnih promjena član ima zakonom uređeno pravo na istup iz društva. Pored prava na istup, manjinski članovi zbog opravdanog razloga imaju pravo tužbom zahtijevati prestanak društva. U radu će biti više riječi o pretpostavkama za istup, postupku istupa kao i njegovim pravnim učincima. Na kraju se donose izvorni zaključci o pravnoj naravi tog instituta.
Granice nehajne odgovornosti za kazneno djelo nesavjesnog liječenja
Authors: Mrčela Marin , Vuletić Igor
Published: July 2018

Kazneno djelo nesavjesnog liječenja ulazi u red medicinskih kaznenih djela stricto sensu. Objekt zaštite kod ovog kaznenog djela jest zdravlje pacijenata koje se štiti od postupaka zdravstvenih radnika koji nisu učinjeni lege artis. Nestručno i nesavjesno postupanje zdravstvenih radnika može imati dalekosežne posljedice, uključujući i smrt. Hrvatska sudska praksa pokazuje da joj takvi predmeti nisu nepoznati. Ipak, hrvatska kaznenopravna literatura je do sada uglavnom zaobilazila ovo vrlo osjetljivo područje, pa je izostala sustavnija rasprava o dometima i granicama kaznene odgovornosti za nesavjesno liječenje. Rješavajući konkretne predmete sudska praksa se može naći u dvojbi oko pitanja pod kojim uvjetima se ponašanje zdravstvenog radnika ima ocijeniti kao nesavjesno, odnosno gdje prestaje odgovornost za nehaj a započinje objektivna odgovornost kod ovog kaznenog djela. Ovaj je rad posvećen upravo toj problematici. Nakon izlaganja općih obilježja ovog kaznenog djela, autori nastoje uspostaviti mjerila za procjenu (ne)postojanja nehajne odgovornosti za nesavjesno liječenje. Svoje teze potom provjeravaju na jednom vrlo složenom predmetu iz novije hrvatske prakse.

In addition, the issue of the organization and jurisdiction of local self-government is treated. The issue of the right to local self-government guaranteed by the Constitution of the Federation of Bosnia and Herzegovina is addressed in this paper. The right of civil servants in the Federation of Bosnia and Herzegovina, the attitude of political structures to professional independence of civil servants and the role and importance that civil servants should have in the processes of exercising civil rights, and the right to local self-government is what the research is focused on. The necessity of harmonization of cantonal legislation on civil service law with federal legislation, and the need to base the civil service law on the principles and standards achieved in the EU is what the paper points out.
(Neke) pravne dvojbe u svezi dopinga
Authors: Kačer Hrvoje , Kačer Blanka
Published: July 2018

Sportsko pravo je još uvijek mlada grana prava, pravna grana u razvitku, što dodatno usložava rješavanje svakog problema koji se pojavi. Pri tome po naravi stvari i rješavanje problema može postati problem odnosno uzrokovati nove probleme. Po mišljenju autora upravo to je slučaj sa borbom protiv dopinga. Doping jest problem koji je prepoznat i protiv kojeg se svjetski sport na svim razinama i jako organizirano i razmjerno uspješno bori, ali ta borba u mnogo čemu znači odstupanje od standarda koji inače vrijede u pravu. Ambicija autora ovog teksta je da se problem dopinga i borbe protiv dopinga što više osvijetli i s pravnog aspekta i da se, što je više moguće, neki pravni problemi preveniraju, a oni već nastali što bolje i što uspješnije riješe. Vrlo konkretno, posebno su analizirana pitanja minimalne pravne edukacije svih čimbenika (uključujući trenere i sportaše) u sportu, individualizacije sankcije i tereta dokaza (uključujući traženi stupanj izvjesnosti glede odgovornosti sportaša).
