Authors: Dridi S. , Mechria A. , Msaddek M.
Published: May 2019

Three aliphatic ligands are synthesized and fully characterized by IR, 1H and 13C NMR spectroscopy. These ligands react with a zerovalent compound Pd(dba)2 in the presence of methallyloxytris(dimethylamino)phosphonium hexafluorophosphate salt [C4H7OP(NMe2)3]+PF6– as an allylating agent for the synthesis of cationic η3-methallylpalladium complexes to give three cationic mononuclear η3-methallylpalladium complexes in high yields. These formed complexes are characterized by IR, 1H NMR and 13C NMR spectroscopy. One of them is characte­rized by X-ray diffraction. A DFT-optimized structure is also discussed.

Актуальність. Незважаючи на значні напрацювання, детальне вивчення біологічних, соціальних та поведінкових аспектів і значення рухової активності для психічного здоров’я людини, відкритими для розгляду й дискусії залишаються питання розуміння механізмів впливу фізичної активності на психічне здоров’я дітей та підлітків. Мета статті – оцінити вплив занять кросфітом на психічний стан і показники якості життя осіб підліткового віку. Методи. У дослідженні взяли участь 14 осіб віком 14–16 років. Тренування з кросфіту тривалістю 1 год відбувалися тричі на тиждень упродовж двох місяців. До складу тренувань входили багатофункціональні комплексні вправи переважно силової спрямованості, які учасники виконували в аеробному режимі в зоні високої інтенсивності, тривалістю не більше ніж 20 хв. Для оцінювання якості життя застосовували анкету PedsQL™ (Generic Core, український варіант для респондентів віком 13–18 років). Уявлення учасників про самого себе («Я»-концепція) вивчали за оцінкою фізичного «Я», настрою, спортивної й академічної компетентностей. Залежні між собою непараметричні вибірки порівнювали за допомогою Z-критерію Вілкоксона. Результати. Після участі у 8-тижневій програмі спостерігали зростання (p<0,01) рівня фізичної підготовленості за результатами виконання комплексів вправ. Середні значення всіх показників «Я»-концепції зростали після участі в про- грамі. Позитивну динаміку спостерігали для показників «Настрій» (р=0,09), «Спортивна компетентність» (р=0,09), «Академічна компетентність» (р=0,10). По завершенню програми показники якості життя зросли на 4–10 балів та перевищували значення 75 балів. Зміни спостерігали щодо показників шкал «Фізичне функціонування» (на 10 %, p=0,1), «Емоційне функціонування» (на 14 %, p=0,09) і «Функціонування в школі» (на 15%, p=0,03). Висновки. Одночасно зі збільшенням рівня фізичної підготовленості, 8-тижневі тренування з кросфіту сприяли зростанню впевненості в собі, поліпшенню настрою. В учасників програми спостерігали зростання показників якості життя на 10–15 %.

Primeiro registro fóssil de Alligatoridae do Mato Grosso do Sul e o valor sistemático das rosáceas em Caimaninae
Authors: Geroto Caio Fabricio Cezar , De Oliveira Alessandro Marques , Janolla Thais Agrella
Published: May 2019

No estado do Mato Grosso do Sul, fósseis de vertebrados Pleistocênicos ou Holocênicos são encontrados majoritariamente em grutas calcárias da Serra da Bodoquena. Além disso, na maioria das vezes os fósseis pertencem à mamíferos de grande porte, como por exemplo preguiças gigantes, tatus, gliptodontes, proboscídeos e grandes carnívoros. No entanto, as ocorrências de outros vertebrados fósseis são raras. Diante do exposto, este trabalho teve por objetivos realizar a primeira descrição de fósseis de Crocodylia provenientes do rio Formoso, próximo à foz com o rio Miranda, no município de Bonito-MS. Em adição, alguns comentários sobre sistemática foram realizados. Os elementos fósseis são dois osteodermos. Embora as características morfológicas dos osteodermos fósseis não permitam a identificação de sua posição precisa (dorsais ou caudais), os resultados das análises comparativas por meio da morfometria linear são sugestivos para identificação de provável Melanosuchus cf. niger, além de um espécime indeterminado de Eusuchia. Uma hipótese plausível seria considerar um possível caso de gigantismo em Caiman latirostris Daudin, 1802, cuja espécie ainda está presente na região. Portanto, os registros apresentados aqui ajudam a compor um quadro sobre a estrutura das comunidades de vertebrados durante o Quaternário Tardio de Mato Grosso do Sul.

Analysis Of Risk Factors Oxidative Stress In Obesity Women
Authors: Hidayati Alpha Olivia , Hardani Ernawati
Published: May 2019

Obesity is a condition of imbalance in the number of calories entered by the number of calories where the excess is heaped up as body fat. Obesity followed by an increase in fat metabolism will cause Reactive Oxygen Species (ROS) production to increase. This condition causes oxidative stress. Indicators of oxidative stress can be observed from plasma levels of Malondialdehyde (MDA). This study aims to determine the risk factors for oxidative stress in obese women.

The results of this study indicate that high fat intake (> 60 g / day) is at risk of increasing MDA-P levels twice. Low fiber consumption (<30 gr / day) gives the risk of an increase in MDA-P levels of 2.09 times. Poor physical activity is a risk factor for MDA-P increase of 1.15 times. High cholesterol (> 200mg / l) and LDL (> 130 mg / l) and low HDL (≤45mg / dl) levels are at risk of increasing MDA-P levels by 1.02 times (cholesterol), 1.13 (LDL) ) and 1.12 (HDL).

Based on this study it can be concluded that high fat intake, low fiber intake, low physical activity, high cholesterol and HDL levels and low HDL levels are risk factors for oxidative stress.

Jatibaru Raya Road Closure: Jakarta Governor's Incremental Policy in Managing the Tanah Abang Market Area
Authors: Permadi Angga Sukmara Christian , Wardani Sri Budi Eko
Published: May 2019

The policy of closing Jatibaru Raya Road on December 22, 2017, has caused new problems because the road closure has caused public losses. The public policy applied by Governor Anies indicated that he had a strong political contract with the community and one of the powerful figures in Tanah Abang so that the policy benefited the people of Tanah Abang who had been disciplined during the previous governor's term. These issues are very relevant to be studied using qualitative methods with a grounded approach to obtain material and in-depth information. Regarding the road closure policy, the existing policy is seen as a step in the realization of Anies campaign promises to establish 200,000 MSMEs at the time of the DKI Jakarta Pilkada in 2017. The public policy for road closure is basically an incremental policy because there are not many policy programs that have been running and was designed during the previous governor's term. The implementation of this policy has made Governor Anies considered maladministration by the Ombudsman, thus giving rise to recommendations for the position of Anies as governor.

Authors: Dhungana Bharat Ram
Published: May 2019

The paper examines the impact of micro-finance on business creation in Nepal through paired sample t-test, chi-square test and Wilcoxon signed rank test. The research is based on primary data collected through structured questionnaires. The survey includes 500 micro-finance clients from four districts of western development region who have been involved in micro-finance programme for last five years. There is a positive association between loan size and its application. The clients who have taken small size of loans, they have mostly spent their loans on domestic purposes and found poor application of loans in micro-business whereas big loan size clients have greater application of loans in productive sectors. The study concludes that micro-business and enterprises creation of people have been significantly improved after involvement in micro-finance programme. Micro finance institutions should give equal priority for non-financial services such as financial literacy and provision of entrepreneurship skills through government and non-government organizations that ultimately helps to utilize micro-credit into productive sectors.
Cyril Shelford, Gasoline, and the Politics of Free Enterprise in Postwar British Columbia
Authors: Penfold Steve
Published: May 2019

This article examines the politics of gasoline prices in British Columbia during the 1960s. It focuses on the “one-price” campaign of Cyril Shelford, a Social Credit member of the legislative assembly from the Omenica riding in the north. In 1963, Shelford forced Premier W.A.C. Bennett to appoint the Royal Commission on Gasoline Price Structure headed by Justice Charles Morrow. Over its sixty-seven days of hearings, the commission became a debate between two different, but overlapping, conceptions of free enterprise, a popular version built on fairness and opportunity for small producers and a more abstract and ostensibly depoliticized market idea preferred by the oil companies. While Shelford’s campaign attracted allies in the interior and the north, his goal of one wholesale price for gasoline faced considerable obstacles. The politics of knowledge at the commission hearings favoured the oil companies, while equal gasoline prices ultimately did not seem to fit the broader developmental politics of the Bennett government. Still, Shelford’s campaign and the Morrow commission point to the importance of oil politics outside producing areas like Alberta and to the social meaning of energy prices during the postwar boom.

Several efforts are underway to commemorate the fiftieth anniversary of the decriminalization of homosexuality in Canada. The problem is that homosexuality was not decriminalized in 1969. This is a myth. The reform added an exception clause to the crimes of buggery and gross indecency that allowed queer sex in private between only two adults. This merely recognized the obvious; the state could not access the bedrooms of the nation using these provisions. At the same time, police forces across the country mobilized to charge queer people not only with gross indecency but also with other sections of the Criminal Code untouched by the omnibus bill, including indecent acts, vagrancy, and the bawdy-house law. When viewed from the perspective of queers and their interactions with the justice system, 1969 was a turning point, but not towards a more progressive society. Instead, it facilitated the recriminalization of homosexuality in Canada.

Abstract: Most policies in the area of mental health recommend the promotion of evidence-based practices. The strengths-based approach is recognized as a practice that can contribute to the recovery of people with severe mental disorders. However, several studies have raised numerous implementation challenges that limit its scope. An evaluation of the implementation process was conducted with stakeholders who received training on the strengths-based approach. The results indicate that training is not sufficient and that institutional commitment is required to ensure the quality of the implementation process.
Secure Data Handling: An Essential Competence for Evaluators
Authors: Czechowski Konrad , Sylvestre John , Moreau Katherine
Published: May 2019

Abstract: Since it is paramount that the rights and welfare of evaluation participants and stakeholders be respected, we argue that the abilities and knowledge necessary to appropriately safeguard data ought to be considered an essential competence for evaluators. Building from past contributions, and in consultation with research ethics and data security experts from our home institution, recommended practices in the collection, handling, and storage of evaluation data were identified. A three-dimensional framework for secure data handling was developed, considering type of information handled, harm posed by a potential confidentiality breach, and corresponding steps to securing confidential information.

Published: May 2019

Abstract: The purpose of this study was to examine the perceptions of the Outcome Questionnaire (OQ) following its implementation in a university-based psychological services training centre. Participants were doctoral-level student clinicians (n = 49), clinical supervisors (n = 17), and clients (n = 24). Data was collected through surveys, semi-structured interviews, and focus groups. Findings indicated that the majority of clinicians used the OQ to monitor outcomes and the majority of stakeholders perceived it as useful. However, the extent to which the information provided by the OQ was being used was variable. Lessons learned for implementation of performance measurement systems within mental health services are discussed.

OBJECTIVE

Indocyanine green videoangiography (ICGVA) has been used in many neurosurgical operations, including vascular and brain tumor fields. In this study, the authors applied ICGVA to intracranial meningioma surgery and evaluated it usefulness with attention to collateral venous flow.

METHODS

Forty-two patients with intracranial meningioma who underwent ICGVA during microsurgical resection were retrospectively analyzed. For ICGVA, the ICG was injected intravenously at the standard dose of 12.5 mg before and/or after tumor resection. Intravascular fluorescence from blood vessels was imaged through a microscope with a special filter and infrared excitation light to illuminate the operating field. The authors assessed the benefits of ICGVA and analyzed its findings with preoperative radiological findings on MRI.

RESULTS

ICGVA allowed real-time assessment of the patency and flow direction in very small peritumoral vessels in all cases. A safe dural incision could also be done based on information from ICGVA. The collateral venous channel due to venous obstruction of tumoral compression was found in 10 cases, and venous flow restoration after tumor resection was observed promptly after tumor resection in 4 cases. Peritumoral brain edema (PTBE) was observed on preoperative T2-weighted MRI in 19 patients. The presence of collateral venous circulation or flow restoration was significantly related to PTBE formation in multivariate analysis (p = 0.001; HR 0.027, 95% CI 0.003–0.242).

CONCLUSIONS

ICGVA, an excellent method for monitoring blood flow during meningioma resection, provides valuable information as to the presence of venous collaterals and flow restoration. Furthermore, the fact that the presence of venous collaterals was found to be associated with PTBE may directly support the venous theory as the pathogenesis of PTBE formation.
Toponymics of the сultural landscape of Yakutia: textualization issues
Authors: Lavrenova O. A. , Filippova V. V.
Published: May 2019

The article considers the problem of textualization of the toponymic space of Yakutia on the basis of the analysis of the field material collected with the support of the Russian Science Foundation (project no. 15-18-20047). It has revealed that the consideration of the cultural landscape of Yakutia as text associated with the secondary meaning of toponymy. The main distinguishing feature of toponymics of Yakutia is the predominance of geological, geomorphological, natural semantics in the local toponymy. Toponyms of Yakutia associated with permafrost have no analogues and were included in Russian geographical terminology. As part of the cultural landscape, toponymics represents one of its semantic layers. The cultural and semiotic approaches are used to identify the features and patterns of the toponymic text existence in the study area.
Universal thermal climate index in Russia
Authors: Vinogradova V. V.
Published: May 2019

The paper uses the universal thermal climate index (UTCI) to estimate the bioclimate in Russia, initiated by the Commission of the International society of Biometeorology. The UTCI index can be described as equivalent environment temperature (°C), which provides the same physiological impact on humans as the actual environment. Assessment of bioclimatic conditions is shown for the territory of Russia in the period of modern climate change (2001–2015). Cold stress conditions (from low to extreme) were observed in the almost all territory of Russia for about 8–11 months a year. During the rest of the year, the conditions are neutral or comfortable. The period of extreme and very high cold stress is reduced during the modern climate warming (compared to the period 1961–1990), especially in the Arctic, in the European part of Russia, in Western and Eastern Siberia. At the same time, the period with neutral and comfortable thermal conditions increases.

The results of biostratigraphic analysis of bottom sediments of the Karas’e, Utinoe, Krugloe lakes as well as loose sediments of accumulative plains at the mouths of the Tumannaya and Poima rivers in the south of the Far East are presented. Natural conditions were recovered and periodicity of vegetation changes in the foothills of the East Manchurian Mountains and in the coastal plains of the Peter the Great Bay in the Middle and Late Holocene were reconstructed by the complex of data. The synchronicity of both the development of vegetation formations and changes of sedimentation conditions with global climatic variations were revealed. The first, Middle Holocene stage proceeded in the conditions of general planetary increase of average annual temperatures, accompanied by flooding of lowland plains of the coast of the Sea of Japan by sea waters. The distribution and species diversity of broad-leaved plants in spurs of the East Manchurian Mountains increased. In the Holocene Optimum, the polydominant forests with richer composition of species than that of the present time were formed and vegetation on the foothill accumulative plains was represented with sedge and mixed meadows. The second, Late Holocene stage was characterized by a decrease in average annual temperatures and series of climatic changes. Its beginning was marked by the cooling, during which the coastal lowlands were freed from sea waters. Climate deterioration caused expansion of dark coniferous and small-leaved plants in the East Manchurian Mountains, as well as reduction of polydominant forests. On the foothills near the coast of the Peter the Great Bay sedge meadows were developed, sometimes there were thickets of shrubby birch (Betula sect. Nanae) and sphagnum swamps. At the end of the Late Holocene the warming occurred again. On the slopes of the East Manchurian Mountains, the vegetation formations with the dominance of Mongolian oak (Quercus mongolica Fisch. ex Ledeb.) and dentate oak (Quercus dentataThunb.), needle fir (Abies holophylla Maxim.), Korean pine (Pinus koraiensis Siеbold et Zucc.) and with the presence of birches began to dominate. The dissemination of pine (Pinus densiflora Siebold et Zucc.), elm (Ulmus sp.), hornbeam (Carpinus cordata Blume) and maple (Acer sp.) has increased. On the foothill lowlands the sedge-reed meadows with different grass dominated.
The Flexural Motions of a Floating Ice Sheet Induced by Moving Vehicles
Authors: Eyre D.
Published: May 2019

An extensive series of tests has been conducted on a Roating ice sheet on a deep, fresh-water lake. A variety of vehicles were driven a long an instrumented test track at a wide range of speeds, producing several characteristic patterns of ice and water response that have been recorded and analysed in detail. Tests were repeated at different stages of ice growth to accommodate changes in physical conditions. The use of a vibration transducer and a new type of deflectometer has permilled the study of many primary and secondary effects. As vehicle speed is increased, the ice and water pass through four characteristic modes of response, culminating in a wave effect at the higher speeds. It has been shown that the ice and water waves travel consistently at the speed of the vehicle. This factor has been used to modify a simple ice-wave theory, which then predicts a linear variation of wave frequency with vehicle speed that can be expressed in a universal form for deep -water conditions. The experimental measurements of frequency confirm this universal variation. The observed secondary effects include air-coupled Rexural oscillations, hydrodynamic Auctuations and systematic variations in ice fracture intensity with vehicle speed. This last effect leads to the proposition of a new criterion of vehicle safety.
Short-Term Forecasting of Water Run-Off From Snow and Ice
Authors: Colbeck S. C.
Published: May 2019

Accurate forecasting of water run-off from snow covers and glaciers is increasingly important because of the increasing competition for scarce water resources. The trend toward conceptual computerized models of hydrologic system, require extensive knowledge of the physical aspects of those systems. Unlike river and stream network>, the hydrological characteristics of snow coven and glaciers are highly variable with time and cannot be easily defined. After reviewing the physical aspects of water flow through snow covers and glaciers, it is concluded that snow covers and glaciers are predictable hydrological systems once the melt metamorphism of the snow is complete and the englacial conduits have been established. However, much additional information about snow and ice masses must be generated before general forecasting techniques can be established for all situations.
Snow Accretion on Electric Wires and its Prevention
Authors: Wakahama Gorow , Kuroiwa Daisuke , Gotō Kazuo
Published: May 2019

This paper presents a study on the accretion of wet snowflakes transported by a strong cyclone on electric wires by means of wind-tunnel experiments and field observations with the aim of successfully preventing them from accreting on and causing damage to power lines and high-voltage power-transmission towers in snowy areas in such countries as Japan, Canada, and the U.S.A. Although extensive studies have been made on snow accretion in Japan since the 1930's by many workers, their studies have been restricted to the coastal regions of central Honshu facing the Sea of japan, which are typified by heavy wet snowfalls of the monsoon type in a weak wind of less than 3 m/s at a temperature between –1° and +1.5+C continuing throughout the day. However, it has long been known that a cyclone characterized by a strong wind exceeding 10 m/s that carries heavier and wetter snowflakes can cause snow accretion on electric wires to grow to 20–30 cm in diameter. Because its detailed accretion processes and mechanism had not been clarified, studies have been made on the growth processes of snow accretion, the adhesive stress of snow to a wire, the structure and texture of the accreted snow, coefficients of collision and collection of snow on the wire, and trajectories of individual snow particles impinging on or passing by a wire at various wind speeds. It has been confirmed that wet snow can accrete on wires at any wind speed between 0 and 20 m/s. Moreover, new techniques have been developed to prevent wet snow from accreting on wires, and these have proved to be effective in situ for any type of snow accretion in Hokkaido.
