The widespread use of Internet of Things (IoT) has effect in a growing number of hardware devices that can be controlled and monitored using a variety of applications. It affects the amount of data that must be collected to be analyzed and processed according to user requirement. The greater the data collected results in requirement of storage media that has access management and scalability that are effective and efficient. The data collected in cloud-based infrastructure namely Openstack. Implementation in this research by involving two physical device of server as main infrastructure that located in network of Faculty of Computer Science, Brawijaya University Malang which used as controller node and compute node. Controller can adapt to the use of various dashboard and provide a good access management service for users to request and create instances in Openstack. The resulting data center shows good performance based on scalability, access, and performance of data transmission from IoT sensors. The test is done gradually by adding requirement of compute nodes up to 24 VCPU, 48 GB of RAM, and 235 GB of HD storage in registered instances. Access at the data center can be done either from faculty internal network (private) and faculty external network (public) with access time under 100 ms.

Background

Hip joint loading in persons with hip osteoarthritis (OA) is not well studied, and its associations with symptoms and lesions are unknown.

Objectives

To determine whether hip joint loading differs between people with and without radiographic hip OA, and to identify its associations with patients' symptoms and cartilage morphology.

Methods

Forty-eight patients (28 male; mean ± SD age, 56.0 ± 12.2 years) with hip OA and 95 controls (40 male; age, 43.2 ± 13.6 years) participated in this cross-sectional analysis. Pelvic radiographs, questionnaires, magnetic resonance imaging (MRI), and gait analysis were conducted. The Hip disability and Osteoarthritis Outcome Score (HOOS) was used to assess symptoms. Cartilage morphology was graded on MRI scans using the Scoring Hip Osteoarthritis with Magnetic Resonance Imaging (SHOMRI) system. Biomechanical variables included peak external hip joint moment (Newton meters per kilogram) and moment impulses (Newton meters times milliseconds per kilogram) in all planes. Generalized estimating equations were used to compare the biomechanical characteristics between groups. In the patients with OA, associations of moment impulses with HOOS and SHOMRI scores were assessed with partial correlations.

Results

The OA group exhibited higher peak external hip flexion and adduction moments (P<.001) and higher hip flexion, adduction, and external rotation moment impulses (P = .001–.039). Increased hip flexion moment impulses were correlated with worse HOOS subscale scores (r = −0.361 to −0.424, P<.05) and worse femoral SHOMRI grades (ρ = 0.256–0.315, P<.05). Increased hip external rotation moment impulses were correlated with worse femoral SHOMRI grades (ρ = 0.283–0.372, P<.05).

Conclusion

Persons with hip OA exhibited abnormally high hip joint loads during walking, and high loads were associated with worse self-reported symptoms and cartilage morphology. J Orthop Sports Phys Ther 2019;49(12):917–924. Epub 14 Oct 2019. doi:10.2519/jospt.2019.8945
Concussion in Combination With Whiplash-Associated Disorder May Be Missed in Primary Care: Key Recommendations for Assessment and Management
Authors: Rebbeck Trudy , Evans Kerrie , Elliott James M.
Published: October 2019

Synopsis

Whiplash and concussion may have similar presenting symptoms, biomechanical mechanisms, and neurophysiological sequelae, but neither enjoys a gold standard diagnostic test. Guidelines for whiplash and concussion are developed and implemented separately. This disparate process may contribute to misdiagnosis, delay appropriate primary care management, and impair patient outcomes. In our clinical commentary, we present 3 cases where signs and symptoms consistent with whiplash were identified in primary care. Symptoms in all cases included neck pain, headache, dizziness, and concentration deficits, raising suspicion of coexisting postconcussion syndrome. All cases were referred for specialist physical therapy. Characteristics consistent with poor recovery in both whiplash and postconcussion syndrome were confirmed, and multidisciplinary management, drawing from both whiplash and concussion guidelines, was implemented. All patients reported improvement in activities of daily living after tailored management addressing both neck and head injury–related factors, suggesting that these conditions were not mutually exclusive. Self-reported outcomes included reductions in neck disability and postconcussion symptoms of between 20% and 40%. It may be appropriate for whiplash and concussion guidelines to be amalgamated, enhanced, and mutually recognized on a patient-by-patient basis. Primary health care professionals might consider minimum screening to identify postconcussion syndrome in patients following motor vehicle collision by administering questionnaires and assessing cranial nerve function, balance, and cognition. Management should then incorporate principles from both whiplash and concussion guidelines and harmonize with available imaging guidelines for suspected spine and head trauma.

Öncelikli hedefi olarak uluslararası barış ve güvenliği korumak üzere kurulan Birleşmiş Milletler (BM), kuvvet kullanma sorumluluğunu taşıması nedeni ile küresel siyasette önemli bir rol oynamaktadır. Daha özelde ise bu önemli sorumluluğu yerine getirmede belirleyici organ olan Güvenlik Konseyi öne çıkmaktadır. Bu önemli yetki Güvenlik Konseyi’nin üyelik kompozisyonunu ve dolayısıyla karar alma mekanizmasını merkezi bir konuma taşımaktadır. Ancak uluslararası alanda meydana gelen değişikliklerin etkisi ve Güvenlik Konseyi’nin sorumluluğunu kullanma biçiminden kaynaklanan sorunlar nedeni ile konsey üzerindeki reform baskıları 1990’lı yıllardan itibaren artarak devam etmektedir. Fakat Vestfalyan sistemin kısıtlarının ve devletlerin güç ilişkilerinin etkisi ile reform çalışmaları başarılı olmamaktadır. Bu nedenle kesin ve köklü reformlar üzerinde yoğunlaşmak yerine, sistemsel realitenin farkında olunarak aşamalı değişikliklerle, hukuki düzenlemelere zemin oluşturacak teamüllerin oluşturulmaya çalışılması yararlı olacaktır.

Forest harvesting is a logging activity, distribution of trunks, skidding, loading and transportation. This activity involves a lot of heavy equipment that results in soil compaction and reduced vegetation cover. This condition causes changes in soil fertility conditions. This study aims to determine changes in soil fertility that occur due to forest exploitation activities. Namely by observing the physical and chemical properties of the soil in the area of the former skid trail, ex-TPn, former TPk, former logging areas. The research method used for data retrieval is the survey method with porposive sampling, while the data obtained is analyzed using descriptive analysis. Based on the results of the analysis of the physical and chemical properties of the soil, it shows that the former TPN area is the area with the lowest soil fertility value. Former logging areas have the best quality of soil fertility compared to other areas; such as former skid trails, former TPk and former Tpn areas even though they are still included in the low fertility classification, with organic matter in the former logged area of 2.24%. The organic matter content is only 0.8% with clay texture.Keyword: harvesting, forest, forest land, soil fertility
Towards Theoretical Spectroscopy with Error Bars: Systematic Quantification of the Structural Sensitivity of Calculated Spectra
Authors: Bergmann Tobias G. , Welzel Michael O. , Jacob Christoph R.
Published: October 2019

Molecular spectra calculated with quantum-chemical methods are subject to a number of uncertainties (e.g., errors introduced by the computational methodology) that hamper the direct comparison of experiment and computation. Judging these uncertainties is crucial for drawing reliable conclusions from the interplay of experimental and theoretical spectroscopy, but largely relies on subjective judgment. Here, we explore the application of methods from uncertainty quantification to theoretical spectroscopy, with the ultimate goal of providing systematic error bars for calculated spectra. As a first target, we consider distortions of the underlying molecular structure as one important source of uncertainty. We show that by performing a principal component analysis, the most influential collective distortions can be identified, which allows for the construction of surrogate models that are amenable to a statistical analysis of the propagation of uncertainties in the molecular structure to uncertainties in the calculated spectrum. This is applied to the calculation of X-ray emission spectra of iron carbonyl complexes, of the electronic excitation spectrum of a coumarin dye, and of the infrared spectrum of alanine. We show that with our approach it becomes possible to obtain error bars for calculated spectra that account for uncertainties in the molecular structure. This is an important first step towards systematically quantifying other relevant sources of uncertainty in theoretical spectroscopy.
Clustering-Triggered Efficient Room Temperature Phosphorescence from Nonconventional Luminophores

Published: October 2019

Pure organic room temperature phosphorescence (RTP) and luminescence from nonconventional luminophores have gained increasing attention. However, it remains challenging to achieve efficient RTP from unorthodox luminophores, on account of the unsophisticated understanding of the emission mechanism. Here we propose a strategy to realize efficient RTP in nonconventional luminophores through incorporation of lone pairs together with clustering and effective electronic interactions. The former promotes spin-orbit coupling and boost the consequent intersystem crossing, whereas the latter narrows energy gaps and stabilizes the triplets, thus synergistically affording remarkable RTP. Experimental and theoretical results of urea and its derivatives verify the design rationale. Remarkably, RTP from thiourea solids with unprecedentedly high efficiency of up to 24.5% is obtained. Further control experiments testify the crucial role of through-space delocalization on the emission. These results would spur the future fabrication of nonconventional phosphors, and moreover should advance understanding of the underlying emission mechanism.
A Note on the Relevance of Semilattice Relevance Logic
Authors: Weiss Yale
Published: October 2019

A propositional logic has the variable sharing property if φ →ψ is a theorem only if φ and ψ share some propositional variable(s). In this note, I prove that positive semilattice relevance logic (R+u) and its extension with an involution negation (R¬u) have the variable sharing property (as these systems are not subsystems of R, these results are not automatically entailed by the fact that R satisfies the variable sharing property). Typical proofs of the variable sharing property rely on ad hoc, if clever, matrices. However, in this note, I exploit the properties of rather more intuitive arithmetical structures to establish the variable sharing property for the systems discussed.

Цель. Изучить возможность уменьшения неблагоприятных эффектов реперфузии на отдаленные органы и системы при острой ишемии конечности.

Материалы и методы. В исследование, проведенное в Институте общей и неотложной хирургии имени В. Т. Зайцева, включены 37 пациентов, оперированных в период с 2016 по 2019 г. по поводу тяжелой острой ишемии вследствие острой проксимальной окклюзии артерий нижней конечности. В 1-й группе (сравнительной) 23 пациентам проводили стандартное лечение. У 14 пациентов 2-й группы (основной) во время восстановления кровотока применяли предложенную методику модифицированной управляемой реперфузии в комбинации с малопоточным гемодиализом в первые 12 ч реперфузионного периода. Изучали динамику концентрации интерлейкинов (IL-1β, IL-6, IL-8, IL-10) и фактора некроза опухоли альфа (TNF-α) в течение 48 ч после операции в периферической венозной крови. Также в раннем послеоперационном периоде оценивали уровни миоглобина, общей креатинфосфокиназы, креатинина и калия.

Результаты. В раннем реперфузионном периоде наблюдали повышение концентрации провоспалительных цитокинов в сыворотке крови, особенно IL-6 и IL-8. Применение предложенного метода управляемой реперфузии позволило в течение первых 2 сут снизить концентрацию IL-6 на 51 - 67%, а концентрацию IL-8 – на треть. Также при применении предложенной методики существенно снижались как пиковые, так и средние показатели уровней миоглобина и общей креатинфосфокиназы в сыворотке периферической крови. Клинически отмечено уменьшение тяжести почечной дисфункции и количества неблагоприятных сердечно-легочных событий.

Выводы. Применение разработанного метода управляемой реперфузии приводит к уменьшению воспалительного ответа и системного влияния продуктов ишемического метаболизма и рабдомиолиза в раннем послеоперационном периоде у пациентов с тяжелой ишемией нижних конечностей.

PUBLIC SECTOR REFORMS AND CONTEMPORARY REFORM CHALLENGES TO SUSTAINABLE DEVELOPMENT IN AFRICA / Public Sector Reforms And Contemporary Reform Challenges To Sustainable Development In Africa
Authors: AGWANDA Billy
Published: October 2019

Since the 1980s, African countries have been undertaking reforms in the public sector to establish effective and efficient public sector management and capacity. This is founded on the need to thrust Africa into sustainable growth through improved public management structures and good governance. These initiatives fall under global drive on sustainable development spearheaded by national governments and international organizations to achieve national and millennium development goals and, address challenges such as poverty, high unemployment rates and quality access to public services and goods. This paper examines the evolution of the African public sector reforms and the challenges that have hindered African states in their attempt to restructure the public sector. It argues that there is need for comprehensive adoption and implementation of organizational mechanisms such as privatization, contractual performance and decentralization as restorative measures in improving public service delivery through enhanced accountability and integrity in the public sector.

Published: October 2019

The purpose of this study is to compare and contrast ways in which two prospective secondary teachers notice mathematics in classrooms when many sources for information compete for attention. Specifically, this research demonstrates how multiple centers of focus of two prospective teachers who set similar learning objectives emerged and how they were systematically organized and eventually transformed by social interaction, material resources, and normed practices throughout the course of preparing, implementing, and reflecting on their own lessons. Teachers’ mathematical noticing were influenced not only by features of mathematical tasks and the nature of mathematical activities but also by ways they interact socially with their students. We finalize our study by discussing implication for the further research and teacher education.

Critical assessment of paradigms in the study of decision making on sport
Authors: Caurel Amaya Castillo , Sánchez José Ignacio Ruiz
Published: October 2019

In this critical assessment of the decision-making process in sport some ideas are clarified around an issue addressed in recent times. To this end, different perspectives are addressed: cognitive paradigm and ecological paradigm with the intention of referring, from a critical point of view, both to their convergences and to their theoretical divergences. A critical assessment is made on their object of study, the theories on which they are based, as well as the fundamental indicators and concepts they handle, based on the study conducted by García, Araujo, Carvalho & Del Villar (2011). Bear in mind that both constitute ways of understanding and explaining the decision process to improve sports performance. Finally, the need to recognize the athlete's behavior as a complex system is exposed, where adaptation with time deficit is of vital importance. It is urged to overcome the vision of each approach in terms of finding convergent points, in an attempt to maximize the best of both perspectives.

One of the environmental issues to be addressed, particularly in the field of refrigeration and air conditioning, is the destruction of the ozone layer and the effects of global warming due to the use of environmentally inefficient refrigerants. In the field of Refrigeration and Air Conditioning, refrigerant as a cooling medium, plays an important role, and until now there is still the use of refrigerant materials that are not environmentally friendly, generally synthetic refrigerant. One alternative refrigerant replacement against the synthetic refrigerant is hydrocarbon refrigerant (HC). On the other hand, several ways can improve the performance of refrigeration system by lowering the temperature of liquid line using liquid to suction heat exchanger. In this study, a numerical simulation was conducted to examine the effect of using liquid to suction heat exchanger on the performance of a unitary air-conditioning system using hydrocarbon refrigerant as a coolant fluid. The results are, liquid to suction heat exchanger increase refrigeration effect by raising heat exchanger effectivity, the highest increase is about 7%. But the use of LSHX also rises up the compression work by increasing heat exchanger effectivity by 19%. So the Coefficient of performance (COP) and relative capacity index decrease by 5%. Decreasing performance is higher in the unit that operates at higher temperatures.

A produtividade da cultura do milho depende da qualidade de semeadura que, por sua vez, está relacionada a fatores edafoclimáticos e operacionais. O objetivo do trabalho foi avaliar o desempenho de uma semeadora-adubadora durante a semeadura do milho de segunda safra (Zea mays L.), em sistema plantio direto. Utilizou-se o delineamento inteiramente casualizado em arranjo de parcelas subdivididas, com três repetições, onde os tratamentos foram dois sulcadores do solo (disco duplo e haste sulcadora), duas profundidades de corte do solo (60 e 80 mm) e três velocidades de semeadura (5,9; 7,2 e 8,6 km h-1). A haste sulcadora, trabalhando na profundidade de corte de 80 mm, proporciona maior porcentagem de germinação a campo e população de plantas, bem como maior profundidade de deposição de sementes. O aumento da velocidade de 7,2 para 8,6 km h-1 reduz o número de sementes por metro, a germinação a campo, o índice de velocidade de emergência e a população de plântulas, independentemente do sulcador usado. Em Latossolo Vermelho distroférrico com baixo teor de água, sob plantio direto, a porosidade do solo e a distância entre sementes não foram afetadas pela alteração do sulcador, da profundidade de corte do solo ou da velocidade de semeadura.

Visto que um dos maiores entraves na produção de organismos aquáticos são os altos custos com alimentação que podem chegar a 50% dos custos totais de produção, dietas elaboradas com ingredientes alternativos como os fungos podem auxiliar na redução de custos de fabricação e ajudar ainda mais a viabilidade dos cultivos. Diante disto, o objetivo do presente trabalho foi avaliar diferentes níveis de biomassa seca de Aspergillus niger (micélio) (0, 2, 4 e 8%) em rações para alevinos de tilápia do Nilo (Oreochromis niloticus) com peso médio de 1,72 ± 0,16 g. O experimento teve uma duração de 42 dias e foi avaliado o desempenho zootécnico, índices organo-somáticos e composição de carcaça. Em relação aos parâmetros zootécnicos não houve efeito significativo para peso final e consumo de ração. Já a conversão alimentar, ganho em peso e taxa de crescimento específico apresentaram diferenças e os melhores níveis de inclusão de biomassa seca de A. niger apontados pela regressão para esses parâmetros foram 3,75, 4,24 e 4,25%, respectivamente. Para os índices organo-somáticos como rendimento de carcaça, índice digestivo somático, quociente intestinal e índice esplenosomático não houve efeito significativo (p>0,05). No entanto pôde ser observado efeito quadrático para índice hepatossomático e índice de gordura visceral em que o melhor nível de inclusão, de acordo com a análise de regressão foram de 5 e 4,75% respectivamente. Os parâmetros de composição de carcaça não apresentaram efeito significativo. De acordo com os dados obtidos, recomenda-se um nível de inclusão de 4% de biomassa seca de A. niger em rações extrusadas para tilápia do Nilo.

Published: October 2019

A logística reversa de embalagens vazias de agrotóxicos no Brasil, possui uma taxa de retorno de 94%, o maior índice mundial. Para que a logística seja eficiente é necessário que as rotas percorridas estejam otimizadas a fim de evitar gastos desnecessários que possam prejudicar o sistema. Neste trabalho é apresentada a aplicação de duas metodologias clássicas de roteirização: Clarke & Wright e Gillett & Miller. Estas metodologias foram utilizadas com a finalidade de encontrar as rotas mais eficientes na logística reversa de embalagens vazias de agrotóxicos. As rotas são responsáveis por ligarem os quinze postos de estudo a uma única central de recebimento, todas no estado de São Paulo. A exploração do tema se deu sob forma de experimento numérico e obteve como resposta uma diferença de 4,9% entre a distância total percorrida por meio das metodologias, sendo que a solução ótima foi obtida pela metodologia de Clarke & Wright.

Os motores a diesel, presentes nas máquinas e equipamentos utilizados no meio agrícola, apresentam-se como principais fontes de emissão de ruído, devido ao processo de combustão. A exposição excessiva a esse agente físico pode provocar danos à saúde dos operadores e reduzir seu desempenho produtivo. Como o biodiesel tem sido inserido gradativamente na matriz energética, objetivou-se avaliar as possíveis alterações na emissão de ruído de motor estacionário a diesel utilizando misturas de diesel/ biodiesel (B25 e B40), sendo estas compostas por blendas de biodiesel de soja e mamona (S100M0, S75M25, S50M50, S25M75 e S0M100), em diferentes rotações (3500, 2900, 2200 e 1500 rpm). Também foi considerado o raio de afastamento da fonte de emissão sonora e a posição em relação ao motor. Os dados foram tratados por meio da análise de variância, teste de Tukey e análise espacial. O uso das blendas de biodiesel de soja e mamona em misturas contendo até 40% de biodiesel no diesel é viável quanto à emissão de ruído, uma vez que as médias não diferem entre si, independente do raio de afastamento, da posição e da rotação, com resultados similares àquele obtido com o diesel B7. A pressão sonora é captada com menor magnitude, conforme o aumento do raio de afastamento, bem como com a redução da rotação. Adicionalmente, verificou-se maior emissão de ruído para a posição esquerda devido à presença do escapamento e necessidade de utilização de proteção auricular em até 3 m de distância do motor.

Authors: Trevisan Alessandra
Published: October 2019

Between ca. 1885 and 1927, Gabriele d’Annunzio and Matilde Serao became friends and contributed to journals in Rome and Naples; they met authors in Europe (especially in France), exchanged opinions about their works and also about their private life. She has been a vibrant constant on Vate’s experience: she gave him advices and protected his affair with Eleonora Duse, who was also Matilde’s friend. Serao’s collection of letters, kept by Fondazione Il Vittoriale degli Italiani in Gardone Riviera, explains some contours of a crucial friendship.
