SOIL STRENGTH CRITERION WITH ACCOUNT FOR SHEAR RESISTANCE CAUSED BY PARTICLE ENGAGEMENT
Authors: MIRNYY A. Yu.
Published: June 2019

Shear resistance of soil becomes vital in geotechnical design of dams and embankments, and also landslides stabilization. Historically, the Mohr-Coulomb yield criterion was used for such problems solving — it appears to be suitable for the most of fine-grained soils. But in case of gravel soils, it was noticed that they possess so-called "cohesion" although there is no physical mechanism of such behavior. This extra shear resistance of non-friction nature is caused by the particle engagement. The engagement phenomenon was usually studied by hydro engineers, but since deep excavations and heavy structures are becoming common in civil engineering, more precise calculation becomes critical. This issue is dealing with the new yield criterion for gravel soils development. The most common criteria for non-cohesive soils and the parameters they are based on are analyzed. The proposed yield criterion is based on invariant stress parameters and concerns friction, cohesion and engagement between particles. It also takes into account second principal stress by using a non-fixed sliding plane. The parameters of this criterion are physically justified and can be determined by a standard soil test. Although it still needs experimental validation, this new criterion appears to be prospective for the usage in numerical modeling, as it is universal and versatile.
SINKHOLE DEVELOPMENT MODEL. PART 2. INVESTIGATION OF THE STRUCTURE OF SINKHOLES IN NATURE
Authors: NESHCHETKIN O. B. , NESHCHETKIN M. O.
Published: June 2019

The main methods of sinkhole research in nature were: the morphometric method, excavations of sinkholes, cone penetration test (CPT) and drilling in the sinkhole zones, the study of the kinematic and dynamic characteristics of the sinkholes and accompanying effects. The study of morphological features of the sinkhole parameters has allowed to establish, that almost everywhere the appearance of the sinkholes corresponds to the elementary geometric shapes: arched — cylindrical — conical — cupped — saucer-shaped. In the case where the covering deposits are represented by clayey soils, most of the karst sinkholes have an arched or cylindrical shape and conical and cupped forms are typical for sandy soils. Excavations of karst sinkholes have established the arch character of the collapse of soils in the intermediate cavity in the development of a sinkhole on the earth's surface. The CPT of the sinkhole zones revealed specific features of the soil decompaction in the sinkhole, which testify to the collapse of the soils into the intermediate cavity. Drilling operations in the conditions of carbonate and sulphate karst have established that the intermediate cavities develop over the karst cavities. In 2015, the authors were lucky to observe the sequence of the sinkhole development on the earth's surface and to distinguish three stages of the sinkhole formation. The results of karst sinkholes investigations in nature conditions and laboratory modeling of the mechanism of their formation are in good agreement and clearly indicate that the destruction of the cover soils over the karst cavities in the collapse of their roofs begins with the formation of a primary intermediate cavity the surface of which is described by an arch of natural equilibrium. Further, there is a successive collapse of the arch of this primary intermediate cavity and the formation of an intermediate cavity at a lower depth. Thus, the intermediate cavity "moves" to the earth's surface. In the initial stage of formation of a sinkhole on the earth's surface, concentric cracks appear and a small saucer-shaped lowering, the formation of an arch sinkhole occurs in the main stage, in the final stage there is a collapse and displacement of blocks of soil with formation of a depression of a steady state.
THE ECOLOGICAL ROLE OF CLAYS AND CLAY MINERALS
Authors: KOROLEV V. А.
Published: June 2019

The article considers the ecological role played by clays and clay minerals in the ecosystem and the biosphere as a whole. The value of clays and clay minerals in the origin of life on Earth and the formation of RNA are analyzed, due to the periodicity of the microstructure of these minerals, their physicochemical activity and sorption capacity with respect to amino acids, nucleotides, proteins and RNA. The processes of interaction of clay minerals with organic matter are considered, including under conditions of hydrothermal conditions, which have specific features that contribute to the origin of life. In addition, the ecological functions of the lithosphere due to clays and clay minerals were analyzed. It is shown that clays and clay minerals perform the most important ecological resource function, being a valuable mineral resource and mineral, participating in providing biota (including humans) with various mineral and energy resources of minerals, in providing biophilic resources, in providing renewable resources (water, oil and gas), in providing resources of the geological space, etc. Also, the clays perform an important ecological geochemical function, which consists in their participation in the geochemistry processes of the lithosphere and the formation of specific geochemical barriers that perform protective ecological functions on the migration routes of various contaminants. The ecological geodynamic function of clays consists in their influence on the development of endogenous and exogenous geological processes affecting the state and functioning of ecosystems. Finally, the participation of clays in ensuring the geophysical ecological function of the lithosphere consists in their influence on the formation of both natural and man-made geophysical fields in ecological-geological systems. Thus, clays and clay minerals have a great influence on ecological and geological systems, they are involved in the formation of all the most important ecological functions of the lithosphere: resource, geochemical, geodynamic and geophysical. Among them, the most significant is the role of clays and clay minerals in ensuring the resource ecological function of the lithosphere.

Aquifers in carbonate karst rocks are characterized by a known extreme heterogeneity of hydrogeological parameters both in the plan and in the section. This paper presents the results of the study of the distribution of permeability and capacity of the Podolsko-Machkovsky limestone aquifer in the scale of the first meters. On the basis of theoretical developments, supported by many years of field experimental research, it is shown that the main elements of the aquifer structure are thin permeable zones formed as a result of the karstification on the contacts of limestone layers of different lithological composition (bedrocks). The zones do not have measurable thickness and are characterized by individual transmissivities and specific capacities varying at distances of about a meter. The zones are separated by relatively low-permeability layers of unkarsted limestone. The methods of flowmetry in the static and dynamic variants, resistivimetry with details in determining the flow rate are used to identify the thin permeable zones. Layer and zone contacts are performed using electrical logging. Changes in the horizon transmissivity and the specific capacity of the zones in the cluster of 7 wells on an area of about 40 m2 with distances between adjacent wells of 3 m, was determined by cross-wells pumping tests with the recording of pressures and temperatures. All applied methods are modified to solve the presented problems. Even in such an area the neighboring wells show the difference of the aquifer conductivity almost one and a half times. Specific capacities of one thin zone vary by an order of magnitude. The asymmetry of the determined parameters at changing the roles of the experimental and observation wells has been revealed. The results allow us to take a new look at the problem of accuracy of the initial information for hydrogeological modeling — the studied area corresponds to the usual block of the model.
ABOUT THE FUNDAMENTAL ASPECTS OF THE GENETIC APPROACH TO THE STUDY OF SOILS
Authors: TROFIMOV V. Т. , KOROLEV V. A.
Published: June 2019

The fundamental methodological and philosophical aspects of the genetic approach to the study of soil formation, the genesis of the composition, structure, state and properties, as well as the role of the spatial position of soils in the array and the role of anthropogenic impacts on soil massifs, including the formation of improved and degraded soils, are considered. In the genetic approach to the study of soils, which became the methodological basis of soil science, is that the composition, structure, condition and properties of soils are considered as the result of their genesis and subsequent postgenetic transformations at the stage of diagenesis, catagenesis, metamorphism and hypergenesis. The distinction of concepts of “soil genesis”, “genesis of soil composition”, “genesis of soil structure”, “genesis of soil condition” and “genesis of soil properties” is shown. When characterizing these concepts, it is necessary to take into account the syngenetic, epi-syngenetic, syn-epigenetic and epigenetic features of soils. In accordance with this, the composition, structure, condition, and properties of soils may be of four classes according to their origin: syngenetic, epi-syngenetic, syn-epigenetic, or epigenetic. The genetic approach plays a particularly important role in the study of anthropogenically-formed and man-made altered soils, as well as in the construction of new genetic classifications of natural and man-made soils. The genetic approach to the study of soils follows from the Priklonsky-SergeevLomtadze law: the composition, structure, condition and properties of soils are determined by their genesis, the nature of postgenetic processes and the modern spatial (coordinate) position. This fundamental approach should underlie the development of new general classifications of soils, which is especially important now, when work is underway to prepare the new GOST 25100 “Soils. General classification”.

The purpose of the study is to evaluate the degree of information and the population opinion regarding the vaccination process. The paper aims to evaluate both the reasons of decreasing the vaccination degree and the sources of wrong information on this topic to better identify between mistakes and correct knowledge.Vaccines are biological products prepared following specifical tehcniques to improve the body's immunity against particula, given conditions. The lives of millions of children from 188 countries who received different vaccines (diptero-tetanus-pertussis, measles, polio) were saved in the world along the time (WHO, 2017). In Romania, the antidifteric vaccination introduced in 1960 made disappear the disease in 1990. No case of diphtheria has been confirmed so far.Unfortunately, in 2016, the vaccine coverage has fallen below 90% (CNSCBT, 2017) because of either parents' refusal and the failure in attending a family doctor.Therefore, today, the society is facing a serious situation caused by: a) insufficient and erroneous information of parents expressing their opposition to vaccination and b) manipulation of organizations against vaccination.

Published: June 2019

Leadership performances develops closely connected to the institutional behaviour and societal culture given the permanent trends to implement changes to update standards according to existing norms and rigors existing in any company. The styles adopted in managing or leading the activities influences the tasks’ achievement, the future path to take and the way success is understood, accepted, shared and disseminated. Nowadays, companies face compulsory the influences of more cultures, given the temptation of delocalisation, the curiosity of working with immigrants, the advantages provided in different situations of accepting a higher exposure of leader to different sides of performance, different dimensions of market and financial profits, new behaviours in managing the employees. Starting from this idea, the purpose of this study is to identify and enquire into the hidden dimensions of organizational culture and how the leadership style impacts the strategic developing and let effective relations spring out.The research is built on a survey based on designed questioner applied to 550 leaders and employees, members of the operation and Maintenance Company of MAPNA (Q&M) in Iran. Data collected refers to MLQ leadership style and Denison's Organizational Culture Questionnaire, and the responses received were analysed with SPSS and Smart Plus software. The findings reveal that the relationship between the leadership style and the organizational culture are strongly linked to each other. Therefore, those leaders able to change and accept to use a transformational style will assist the company to move forward faster that those who adopt and keep the transactional style as the single one to prove important.

The paper states the necessity to implement a new model of management in the health sector, based on a new concept, of synergetic satisfaction having an institutional relation between patient and medical entity in its centre.The present doctoral research finds its roots in the interdisciplinary approach linked to Health industry and market, as profitable businesses. The purpose encounters the anchor into a new concept, of synergetic satisfaction having the patient in its centre. The measurement centre resides in the societal performances’ rules linked to the real needs of a health status afterthought. Several constituents of the classical healthcare principles receive, exquisitely, shaped clarifications under the state, public and private health of public recognition. As the principles of humanism depict the governments’ obligation to guarantee their citizens fundamental rights to access health services, the international dimension of activities seed new designed health objectives. Hence the research maps a new model sustaining that the health management systems, differently recognized, can assume regular nudgers to better drive the understanding of the reality, close to financial interests and realistic resources. The implementation of the innovative and realistic reform would diminish the national burden, make people embrace the responsibility of active citizenship letting them to get involved in any process that protect the right development of a country and its citizens, far from partisan interests, only for their own future and comfort in life.

Objective – to improve treatment results of patients with ruptured brain aneurysms using follow-up cerebral digital subtraction angiography to avoid de novo or aneurismal regrow.Materials and methods. Analysis of follow-up cerebral digital subtraction angiography and treatment results of two patient (60 and 64-year-old females) with brain anterior communicated artery de novo aneurysm and regrowed aneurysm of an anterior communicated artery after microsurgical clipping.Results. Two patient underwent endovascular treatment of ruptured brain aneurysms after non follow-up cerebral digital subtraction angiography. In first case de novo aneurysm of anterior communicating artery and in second – regrowed aneurys of anterior communicating artery after surgical clipping. Both patients were discharged from the clinic in I and IV modified Rankin scale. Conclusions. Digital subtraction angiography follow-up of intracranial aneurysms treated by endovascular or microsurgical approach is important for the detection and prediction for the risk of bleeding (aneurysm recurrence and de novo aneurysm). There exist no guidelines on the frequency of monitoring and imaging modality to adopt and the monitoring is adapted on a case-by-case basis. Digital subtraction angiography is the gold standard for the evaluation of aneurysmal occlusion after coiling and microsurgical clipping and remains also necessary for evaluating other devices.

Objective — to evaluate the effectiveness of endovascular mechanical recanalization methods in ischemic stroke and the analysis of problem cases.Materials and methods. A retrospective analysis of the results of treatment of 33 patients with acute ischemic stroke due to occlusion of a large vessel was performed. There were 18 (54.5 %) men and 15 (45.5 %) women. Endovascular interventions were performed in all patients to restore cerebral arteries patency using various methods and techniques of mechanical thrombectomy. All patients underwent neuroimaging (CT of the brain and selective cerebral subtraction angiography). A topographical assessment of early CT-changes in ischemic stroke was performed using the ASPECTS scale. The severity of neurological symptoms in the acute period of ischemic stroke was assessed according to the NIHSS score. The severity of the condition – on the NIHSS score. The mTICI scale was used to assess the success of recanalization (reperfusion) after mechanical thrombectomy.Results. Successful recanalization (mTICI 2b-3) with the use of stent retrievers and distal aspiration catheters was achieved in 22 (66.7 %) cases. The total number of intraoperative complications was 12.0 %. Mortality rate – 12.0 %.Conclusions. Endovascular reperfusion methods using stent retrievers and distal aspiration catheters for acute ischemic stroke are effective. Endovascular reperfusion advisable to start with a mechanical thrombus aspiration. When performing endovascular recanalization, the use of stent retrievers in combination with guide balloon catheters only without distal aspiration catheters increases the risk of distal reembolism and embolism of other arterial basins.

A case of treating of 59 years old patient with a multifocal occlusive and stenotic lesion of the main arteries of the head is described. Patients has occlusions of both internal carotid arteries, left external carotid artery, right vertebral artery, severe stenosis in the initial segment of the left subclavian artery and severe stenosis in the ostium of the left vertebral artery, with cognitive impairment and coordination disorders.A single-session stenting of the stenosis in the ostium of left vertebral artery with balloon-expan-dable elution-stent with usage of the modified Szabo anchor technique and stenting of the stenosis in the initial segment of the subclavian artery with a balloon-expandable peripheral stent was performed. Stenoses are eliminated, all cerebral arteries of the vertebrobasilar basin and both carotid basins are supplied by the left vertebral artery.After 50 days, the patient’s neurological status was assessed and a computed tomographic perfusiography of the brain was performed. The cognitive status improved significantly (initially – 23 points on the MoCA scale, after the operation – 27 points), coordination disorders regressed. According to computed tomographic brain perfusion, there are increase in CBF (cerebral blood flow) above normal in all areas except for the area of ​​stroke; an increase in CBV (cerebral blood volume) above normal, which is a reflection of arterioles vasodilation; increase in MTT (mean transit time) in all zones, which is a sign of collateral blood flow. Based on these data, it was concluded that further revascularization operations on the occluded cerebral arterial basins can lead to the hyperperfusion syndrome clinical manifestation. The performed endovascular stage of treatment was effective and sufficient to significantly improve the patient’s neurological and cognitive status and prevent the development of recurrent ischemic stroke.

Published: June 2019

Accidental carotid cannulation using a large-bore catheter is one of the complications of central venous catheter insertion, reported in 1 % of performed procedures. Management of arterial catheterization contains direct manual compression, endovascular treatment, and open surgical repair. Inadvertent arterial cannulation can lead to hemorrhage, pseudoaneurysm, arteriovenous fistula, stroke or death. Mechanical removal of thrombotic material is presently the most effective method of stroke treatment. Rapid and early restoration of blood flow is crucial for the improvement of the neurological condition. This report describes a case of a patient with signs of severe stroke after management of accidental carotid catheterization using balloon tamponade. Aspiration thrombectomy was successfully performed to manage acute ischaemia of the brain.

Mediante encuesta se indagó consumo de camarón y control del asma o rinitis. Se realizaron pruebas de provocación oral con camarón a los individuos sensibilizados a ácaros y camarón sin consumo, o con consumo mayor a seis meses, sin historia de reacción. En un subgrupo se midió la sIgE para camarón, Der p y Lit v 1. Se compararon los pacientes sensibilizados a ácaro y camarón (casos) y los sensibilizados solo a ácaros (controles).Resultados: De 229 pacientes, 48 (21 %) se encontraban sensibilizados a camarón. No hubo diferencia estadísticamente significativa en la ingesta de camarón entre casos (54.2 %) y controles (49.7 %); ocho casos presentaron síntomas al contacto con camarón. No se encontraron diferencias estadísticamente significativas en la sIgE para Der p, Lit v1 y camarón entre casos y controles. Se observó cambio mediano en la magnitud de efecto: 0.45, 0.44 y 0.41, respectivamente.Conclusiones: La sensibilización a camarón en pacientes con asma o rinitis alérgica por ácaros es alta, en 25 % parece ser clínicamente relevante, principalmente en aquellos con asma. La ingesta no es la principal vía de exposición a la tropomiosina; la reactividad cruzada puede explicar la frecuencia de sensibilización.

Allergic rhinitis and nasal polyps had the most serious deterioration according to the fern test (type IV).Conclusions: The fern test is effective for assessing mucus alterations in patients with rhinitis and it could be included as a new parameter in the study of rhinitis as a potential biomarker of the function of damaged epithelial cells.
Analysis of Impacts of Land Use Changes in Kitengela Conservation Area on Migratory Wildlife of Nairobi National Park, Kenya
Authors: Wandaka John K.M. , Francis Kabii M.
Published: June 2019

Nairobi National Park (NNP) in Kenya was established in 1946 to conserve the abundance and diversity of wildlife in the Kitengela-Athi-Kaputei plains, from excessive exploitation. It is currently fenced except on the Kitengela side across the Mbagathi River due to the sub-division of the group ranches, which commenced in the 1980s, limiting access of wildlife to the migratory corridor and dispersal areas. This paper is based on a study conducted to assess the impacts of the resultant land use changes in the Kitengela dispersal area/ migratory corridor on the migratory fauna of NNP, and to identify appropriate mitigation measures. The findings indicated that increased human settlement, led to changes in land uses which resulted into multiple negative impacts on the migratory wildlife of Nairobi National Park, mainly due to loss of dispersal area and blockage of migratory routes, leading to wildlife confinement, decreased wildlife tolerance and increased incidences of human wildlife conflicts. Data analysis indicated decline in migratory wildlife population thus negative effect (F=, 6.066, p<0.05). The findings also indicated that loss of migratory routes/dispersal area and reduced vegetation cover was regarded by 55% of the local community respondents as one of the main consequences of the land use changes resulting from the subdivision of the group ranches leading to decreased wildlife tolerance (β = 0.246) and wildlife confinement (β = 0.371) in NNP (p= 0.021, < 0.05, F= 2.678; R=0.179, R2= 0.032). The paper also discusses the mitigation measures for the longtime sustainability of the park, the dispersal area and migratory corridor, including holistic implementation of the Kitengela-Isinya-Kipeto Local Physical Development Plan, mapping and protection of the vital wildlife areas within the migratory range, including the wildebeest calving area in North Kaputiei.

Muhammad Abduh and Ahmad Mustafa al-Maraghi are teachers and students. As a student of Muhammad Abduh, of course Mustafa al-Maraghi has many similarities. Uniquely, even though the similarities are more prominent, the interpretation of al Maraghi seems more acceptable, considered to be more straightforward, rather than the interpretation produced by Rashid Ridho and his teacher. Regarding the verse above, their interpretation tends to be different. Based on this fact, the authors are interested in examining further how the interpretations of Muhammad Abduh and Mustafa al-Maraghi as modern Mufassir are related to the legal verses in the Qur'an regarding the issue of interfaith marriage. Then the author will do a comparative analysis of their opinions or the results of the methods they use in their interpretation. the author only focuses on the interpretation of interfaith marriage verses in surah al Baqarah 221 and al Maidah 05 according to the interpretation of al-Manar and the interpretation of al-Maraghi. But these two verses are supported by verse 10 of Surat al Mumtahanah.

Muhammad Abduh dan Ahmad Mustafa al-Maraghi adalah seorang guru dan murid. Sebagai seorang murid Muhammad Abduh, tentu saja Mustafa al-Maraghi mempunyai banyak persamaan. Uniknya, meski persamaannya lebih menonjol, namun tafsir al Maraghi tampaknya lebih dapat diterima, dianggap lebih lurus, daripada tafsir yang dihasilkan Rasyid Ridho dan gurunya. Terkait ayat di atas, penafsiran mereka cenderung berbeda. Berdasarkan fakta ini, penulis tertarik untuk  mengkaji lebih jauh bagaimana penafsiran Muhammad Abduh dan Mustafa al-Maraghi selaku Mufassir modern terkait ayat-ayat hukum dalam al-Qur’an terkait masalah pernikahan beda agama. Kemudian penulis akan melakukan analisis komparasi terhadap pendapat mereka atau hasil dari metode yang mereka pakai dalam penafsiran mereka. penulis hanya memfokuskan penelitian terhadap penafsiran tentang ayat-ayat nikah beda agama  dalam surah al Baqarah 221 dan al Maidah 05 menurut tafsir al-Manar dan tafsir al-Maraghi.  Tetapi dua ayat tersebut didukung oleh ayat 10 surat al Mumtahanah.

As metodologias ativas de ensino-aprendizagem são um desafio tanto para o docente quanto para o discente e instituições de ensino. O presente estudo objetivou diagnosticar as condições mais favoráveis ao aprendizado, comparando diferentes métodos de ensino sobre montagem de articulador semiajustável (ASA) para estudantes de terceiro período da Faculdade de Odontologia São José, Rio de Janeiro, Brasil. Participaram deste estudo 140 estudantes divididos em dois grupos, Grupo I: Leitura de artigo e aula expositiva e Grupo II: Peer Instruction (PI).  Foram avaliados o nível de participação nas atividades propostas, a forma como o conhecimento era construído, o número de erros e acertos obtidos nas atividades práticas, além do domínio do assunto abordado e a postura profissional do aluno.  Observou-se que no Grupo I 6 (21,4%) estudantes realizaram correta montagem dos modelos e no Grupo II 26 (29,2%) apresentaram este resultado. Os erros mais prevalentes ocorreram nas fases compensação de cera (Grupo I: 18 - 35,3%; Grupo II: 26 - 29,2%) e registro intermaxilar (12 - 23,5% no Grupo I; 17 - 19,1% no Grupo II). O resultado obtido comprovou que a proposta de ensino PI, empregada no Grupo II, favoreceu o aprendizado, uma vez que houve aumento do número de acertos nas atividades e domínio dos conceitos que envolvem o manuseio e a operação dos equipamentos utilizados.

Published: June 2019

O processo de ensino-aprendizagem vem passando por muitas mudanças ao longo dos anos, um dos motivos é buscar adaptar-se à geração de estudantes das escolas e universidades. Essa adaptação vem ocorrendo também no currículo dos cursos de nível superior, dentre eles, a Odontologia. Uma forma de registrar tais mudanças é a análise do projeto pedagógico dos cursos (PPC) de Odontologia. No PPC existem informações vitais e importantes sobre o objetivo, o curso, disciplinas obrigatórias e optativas, bem como os procedimentos de ensino que os docentes estão utilizando. O objetivo do presente estudo foi verificar os procedimentos de ensino registrados no PPC do curso de Odontologia da Universidade Federal do Espírito Santo (UFES) e comparar com os procedimentos de ensino citados pelos docentes que atuam no ciclo profissionalizante, por meio de entrevista baseada em roteiro. Na pesquisa documental do PPC foram incluídas 50% (15) das disciplinas do ciclo profissionalizante (5º ao 10º período). A seguir, foram entrevistados os docentes destas disciplinas lotados em três departamentos - Clínica Odontológica, Prótese Dentária e Medicina Social – os quais foram selecionados aleatoriamente. O procedimento de ensino mais frequentemente citado pelos docentes foi a aula expositiva (93%), seguido de seminário (40%). No PPC o procedimento de ensino registrado mais frequentemente foi o seminário (91%), seguido da aula expositiva (83%). Outros seis procedimentos de ensino foram citados pelos docentes e registrados no PPC, dentre eles a pesquisa bibliográfica, aprendizado baseado em problema, estudo dirigido, grupo de estudo, discussão e problematização. Existe pouca diversidade nos procedimentos de ensino citados pelos docentes entrevistados e descritos no PPC de Odontologia da UFES. Pode-se concluir que existe alguma dificuldade por parte dos docentes entrevistados para adotar novos procedimentos de ensino.
The Application in the Sensitization of Titania : Zinc Porphyrin-Functionalized Fullerenes as a Visible-Light Active Photocatalyst

Published: June 2019

Zinc porphyrin-functionalized fullerene [C60] derivatives have been synthesized and usedto prepare titania-based composites. The electrochemical properties and HOMO andLUMO levels of the photosensitizers were determined by electrochemical measurements.Raman and IR techniques were used to study chemical groups present on the titaniasurface. Absorption properties of the composites were measured in the solid state bydiffuse reflectance UV-Vis spectra (DRS).
Accuracy and bias in the social perception of envy
Authors: Lange Jens , Hagemeyer Birk , Lösch Thomas , Rentzsch Katrin
Published: June 2019

Research converges on the notion that when people feel envy, they disguise it towards others. This implies that a person’s envy in a given situation cannot be accurately perceived by peers, as envy lacks a specific display that could be used as a perceptual cue. In contrast to this reasoning, research supports that envy contributes to the regulation of status hierarchies. If envy threatens status positions, people should be highly attentive to identify enviers. The combination of the two led us to expect that (a) state envy is difficult to accurately perceive in unacquainted persons and (b) dispositional enviers can be accurately identified by acquaintances. To investigate these hypotheses, we used actor-partner interdependence models to disentangle accuracy and bias in the perception of state and trait envy. In Study 1, 436 unacquainted dyad members competed against each other and rated their own and the partner’s state envy. Perception bias was significantly positive, yet perception accuracy was non-significant. In Study 2, 502 acquainted dyad members rated their own and the partner’s dispositional benign and malicious envy as well as trait authentic and hubristic pride. Accuracy coefficients were positive for dispositional benign and malicious envy and robust when controlling for trait authentic and hubristic pride. Moreover, accuracy for dispositional benign envy increased with the depth of the relationship. We conclude that enviers might be identifiable but only after extended contact and discuss how this contributes to research on the ambiguous experience of being envied.
LEXICAL CATEGORIES: CONCEPT MAPPING INSTRUCTION ON THE EFFECT OF NOUN IDENTIFICATION IN FOREIGN LANGUAGE TEXTS

Concept maps basic training differences were examined in noun identification from written texts, in the context of reading and writing assignments in a foreign language. Sample groups were comprised of 10-year-old Spanish primary students who attend a bilingual school. Both male and female participants were included in the non-randomized experiment. Experimental and control sample groups were accurate in identifying singular and collective nouns, including plural irregular nouns. Although the trained sample group was efficient in detecting and categorising hypernyms and first hyponyms, compared to lower hyponym categories, pupils did not precisely discriminate adjectives within the texts, sometimes confusing them with nouns. In contrast, while the non-trained sample group disclosed precision in circling nouns and discriminating adjectives within the texts, they demonstrated less precision identifying other grammatical categories. The control sample group did not reveal accuracy discriminating verbs, adverbs, and pronouns from nouns when compared to the experimental group. Because of their lack of training, the control group displayed more creativity (charts, mind maps, tree diagrams...) when asked to create concept maps, in comparison to the experimental group. However, the trained group accomplished this activity satisfactorily. The outcome of this study reveals that a three-month trained concept mapping sample group disclose achievement in discriminating specific information from English texts. These conclusions suggest that concept mapping helps students differentiate lexical and grammatical categories from written foreign texts, which will benefit them when synthesizing the information to be learned.

Published: June 2019

Graphene oxide (GO) was modified by two modified porphyrins (THPP and TCPP) to formGO–porphyrin hybrids. Spectroscopic measurements demonstrated the formation of stablesupramolecular aggregates when mixing two components in solution. The Fouriertransform infrared (FTIR) and Raman scattering measurements confirm π-stackingbetween hydrophobic regions of GO nanoflakes and porphyrin molecules. An interesting interplay between modifiers andthe surface of GO leads to a significant change in electronic structure and magneticproperties of the designed hybrid materials. Based on the selection of molecularcounterpart we can affect the behavior of hybrids upon light irradiation in a different manner,which may be useful for the applications in photovoltaics, optoelectronics, and spintronics.
