Avaliação do Caráter das Praças de Umuarama – PR
Authors: Cardoso Carolina , Miranda Yara Campos , Angelis Bruno Luiz Domingos De
Published: December 2017

Os espaços livres estão enraizados na urbanização das cidades brasileiras desde o período colonial. O planejamento e o projeto de novas cidades impulsiona a criação de espaços livres, como no caso do município de Umuarama – Paraná. A cidade, fundada no ano de 1955, possui um sistema viário radial, fundamentado no conceito de Cidade-Jardim, que utiliza malhas ortogonais e diagonais no traçado das vias. Este plano possibilitou a implantação de diversas praças, que fazem parte da história da cidade por estarem presentes desde a sua fundação, ainda que seja recente. O objetivo deste artigo é analisar os espaços livres da cidade de Umuarama – PR. Para isto, foi realizado um estudo de caso nas praças Santos Dumont, Arthur Thomas e Miguel Rossafa, localizadas em região central e previstas no projeto original da cidade. O método utilizado nesta pesquisa compreende a análise do caráter de praças históricas, proposto por Yamaki (2008). O método propõe dez critérios de análise que envolve a avaliação tanto da estrutura da praça, quanto da sua história. A síntese da análise é apresentada em forma de um gráfico radar. Os resultados mostram que a falta de significação histórica não prejudica a percepção geral do espaço livre.

Forecasting Farm-gate Catfish Prices in Uganda Using Sarima Model
Authors: Bukenya James Obadiah
Published: December 2017

Stabilization of prices of essential agricultural commodities continues to remain an area of major concern for policy makers; given that price instability affects both producers and consumers, and has macroeconomic implications. This paper examines farm-gate price behavior in the African catfish markets in Uganda, and develops a forecasting model that adjusts for the seasonal fluctuations in the price series. The analysis utilizes monthly catfish real price series for the period January 2006 to December 2013. The model provides good in-sample and out-of-sample forecasts for the eight-year time period. The out-sample predictions based on SARIMA (1, 1, 1) (0, 1, 1)12 model suggest that the stochastic seasonal fluctuations depicted in the price series are successfully modeled, and that catfish real prices follow an upward trend. The findings can assist policy makers and major stakeholders to gain insight into more appropriate economic and sectorial policies that can lead to the development of reliable market information systems and up-to-date data on catfish supply, demand and stocks.

One may introduce a concept of Hawking irreversibility as the point where temperature has risen so much that the global warming consequences threaten the survival of mankind. The recent news out of China that its CO2s are increasing again makes this term highly policy relevant. Moreover, the methane emissions have started to augment, which also calls up Hawking irreversibility. The drive behind these dire developments is the endless zest for affluence and wealth, fueled by ever larger energy consumption. Asian miracle economies should take this warming seriously and srart the implementatuion os COP21 Treaty.
No Longer Junior Colleges: Integrating Institutional Diversity in Graduate Higher Education Programs
Authors: L Lebron Jennifer , Lester Jaime
Published: December 2017

Aim/Purpose: This article argues that given the isomorphic pressures on both community colleges and four-year institutions, historic divisions between community college leadership programs and general higher education programs are no longer serving the needs of new scholars and practitioners in the field. Graduate programs of higher education should integrate an understanding of community colleges and institutional diversity in meaningful ways throughout a graduate curriculum now focused on four-year institutions.

Background: Community colleges and four-year institutions are engaging in isomorphic change which is weakening traditional boundaries between these sectors to create a more integrated system of higher education.

Methodology: Using a framework of institutional isomorphism, this article reviews recent literature on changes within community colleges and four-year institutions and provides recommendations for infusing this isomorphism into graduate higher education programs.

Contribution: By infusing an understanding of institutional diversity into all graduate course-work, educators can prepare future scholars and practitioners for a changing higher education landscape and expand beyond reductive representations of the higher education field.

Published: December 2017

Two unicellular green microalgae, were isolated from Amani Shah Nallah (Jaipur, India) that receives discharge of dyeing industries. Preliminary morphological characterization using light microscopy showed ovoid, fusiform shape of cells with single to two celled coenobia in a culture suspension. Transmission electron microscopy (TEM) analyses depict abundant chloroplast located at the periphery of the cell, a pyrenoid as well as nucleus is visible in the centre. A well developed cell wall with many layers is also evident in TEM. Phylogenetic position and genetic variabilty among the isolated microalgal strains were investigated by 18S rDNA sequence analysis. The results suggest that the isolated microalgae belongs to family chlorophyceae and corresponds to genus Scenedesmus and genus Acutodesmus. Growth profile of both microalgal strains showed a typical sigmoid curve with specific growth rate of µmax, 0.839 day-1 and 0.654 day-1 for Scenedesmus sp. and Acutodesmus obliquus, respectively. The strains were allotted with MCC numbers by IARI, New Delhi as MCC26 for Scenedesmus sp.  and MCC33 for Acutodesmus obliquus.Int. J. Appl. Sci. Biotechnol. Vol 5(4): 415-422

Brucellosis; a zoonotic disease which is caused by Brucella sp. viz; abortus, melitensis, ovis, canis, suis, in Nepal is regarded as one of the occupational and public health hazards for veterinarians, animal attendants, dairy man, slaughter-house workers, butchers and meat sellers. This study aimed to determine the prevalence of brucellosis in pigs of Bhaktapur, Kavre and Banke districts of Nepal. Serum samples of 231 pigs were collected purposively of which, 78 samples were from Bhaktapur, 85 from Kavre and 68 from Banke districts. Blood samples were collected from the jugular vein of the pigs and were centrifuged to separate the serum from the blood. The separated serum samples were stored at -20°C in the NARC lab till the test was done. Out of 231 samples, 3.90% (9/231) of samples were found to have sero-positivity towards brucellosis by using indirect ELISA test through ID Vet iELISA kit 2016. Fisher exact test was used to find association between variables. There was no significant differences (p>0.05) on sex-wise prevalence. This study shows a potential threat to the public health sector of the country along with the degradable impacts on animal health including the economy of farmers. Thus, timely implementation of appropriate preventive and control strategies should be adopted to eradicate the disease.Int. J. Appl. Sci. Biotechnol. Vol 5(4): 466-469

Authors: Jahan Nafisa , Rahman KBM Abdur , Nadiruzzaman -
Published: December 2017

Introduction: Osteoporosis or low bone mass is one of the systemic effects of the chronic obstructive pulmonary disease (COPD). Fracture may occur as a complication of low bone mass in these patients that increases the morbidity. There is lack of awareness about the decreased bone mass in these patients.  There is significant need to screen those patients who are at risk, so that early diagnosis can be made and preventive and or therapeutic measures can be taken to avoid the consequences of osteoporosis. Dual energy X-ray absorptiometry (DEXA) is the current gold standard for the diagnosis of osteoporosis or low bone mass.    Objective: To evaluate the bone mineral density of the chronic obstructive pulmonary disease patients with dual energy X-ray absorptiometry and compare with the controls (non-COPD patients).    Method: In the period of January 2010 to December 2010 a total number of 100 subjects were included in the study. Among them fifty patients were with chronic obstructive pulmonary disease and fifty apparently healthy persons without chronic lung diseases taken as comparison group controls.  Bone mineral density (BMD) of lower lumber spine (L1-L4) and left femoral neck were measured by Lunar DPX pro (GE) scanner. Low BMD was defined according to World Health Organization (WHO) criteria based on T score of patients and were compared with the controls.    Results: BMD was significantly low in COPD patients than in control group. At femoral neck, low BMD was found among 84% of patients with COPD and 36% of controls without COPD. At lumber spine low BMD was found among 86% of patients with COPD and 60% of patients without COPD.    Conclusion: This study suggests that bone mineral density is low in chronic obstructive pulmonary disease.Bangladesh J.

An Agent-based Simulation of a QoS-oriented Supply Chain
Authors: Gumzej Roman , Rosi Bojan
Published: December 2017

With adaptive customer-orientation the efficiency of supply chain management is improved substantially. By the introduction of service quality-based decision-making into supply chain management the quality of service (QoS) within supply chains is expected to improve autonomously and continuously up- and downstream. In the paper the main characteristics of quality of service oriented supply chain management are outlined. The quality of service criterion, introduced into the adaptive supply chain model, provides market regulators and managements with the needed information and feedback to their increasingly informed decisions. By an experiment comprising several typical scenarios on our agent-based simulation model it was possible to empirically verify the expected impact of quality of service-based reasoning on generic adaptive supply chains.

Published: December 2017

Voltage‐gated sodium channels are crucial for electro‐signalling in living systems. Analysis of the molecular mechanism requires both fine electrophysiological evaluation and high‐resolution channel structures. Here, we optimized a dual expression system of NavAb, which is a well‐established standard of prokaryotic voltage‐gated sodium channels, for E. coli and insect cells using a single plasmid vector to analyse high‐resolution protein structures and measure large ionic currents. Using this expression system, we evaluated the voltage dependence and determined the crystal structures of NavAb wild‐type and two mutants, E32Q and N49K, whose voltage dependence were positively shifted and essential interactions were lost in voltage sensor domain. The structural and functional comparison elucidated the molecular mechanisms of the voltage dependence of prokaryotic voltage‐gated sodium channels.

Activation of KLF4 expression by small activating RNA promotes migration and invasion in colorectal epithelial cells
Authors: Zhou Qinqin , Fan Dejun , Huang Kejun , Chen Xiuting , Chen Yufeng , Mai Qingyun
Published: December 2017

RNA activation mediated by small double‐stranded RNAs targeting promoter sequence named small activating RNAs (saRNAs) is one of the mechanisms for gene activation. Artificial regulation of gene expression through RNA activation does not affect the alteration of the genomic DNA sequences or exogenous plasmid DNA, therefore it is a relative manageable approach for gene perturbation. KLF4 is a member of zinc‐finger transcription factors and its functions in colorectal cells are still controversial. In order to elucidate the functions of KLF4, we synthesized saRNAs that target the promoter regions of KLF4 and transfected into varied colorectal epithelial cell lines. We found the KLF4 gene expression is specifically increased in the human normal epithelial cell NCM460 and colorectal epithelial cancer cell Caco‐2 and HCT116, but not in other human colorectal epithelial cell lines. In addition, we observed that saRNAs induced overexpression of KLF4 could promote cell migration/invasion in NCM460 and HCT116 cell lines. This effect is mediated partly by inducing EMT and facilitating nuclear translocation of β‐catenin.
A Metal–Organic Framework Supported Nonprecious Metal Photocatalyst for Visible‐Light‐Driven Wastewater Treatment
Authors: Tilgner Dominic , Friedrich Martin , Verch Andreas , de Jonge Niels , Kempe Rhett
Published: December 2017

The utilization of abundantly available elements in key technologies is a promising way to save precious and rare metals. Iron and titanium offer the highest abundance of all transition metals in the earth's crust and their application in catalytic processes is preferable regarding sustainable material development. The photocatalytic decontamination of wastewater using visible‐light‐responsive materials is of high interest due to the demand for clean water and the increasing accumulation of harmful organic compounds resulting from medical or industrial waste. Herein, we report a novel photocatalyst based on the generation of crystalline Fe2O3 and TiO2 on size‐optimized colloidal metal–organic framework crystallites. The reusable photocatalyst permits the efficient oxidative degradation of pharmaceutical compounds and toxic dyes under visible‐light illumination and without the requirement of additives or noble metals. We observed a higher photocatalytic activity for our Fe2O3/TiO2@MIL‐101 material than for commercially available Fe2O3, TiO2, and TiO2 (P25).

Published: December 2017

A highly efficient, single‐step, metal‐free synthetic approach to the synthesis of coumarin‐3‐carboxamides has been developed. The protocol employs tert‐butyl peroxybenzoate as a radical initiator to achieve the regioselective carboxamidation of coumarins at C‐3 in good‐to‐moderate yields. The established reaction protocol offers a wide substrate scope as it allows the use of both formamides as well as aldehydes as coupling partners with excellent regioselectivity. Furthermore, mechanistic investigations illustrate that the reaction proceeds by a free‐radical pathway.

A NiMo‐ceria‐zirconia catalyst was developed for an inert‐substrate‐supported tubular single cell running on isooctane fuel. The tubular single cell consisted of an inert porous yttira‐stabilized zirconia (YSZ) supporter, Ni‐Ce0.8Sm0.2O1.9 (Ni‐SDC) anode, YSZ/SDC bilayer electrolyte and La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) cathode. The NiMo‐ceria‐zirconia catalyst was packed in the tubular channel of the single cell as a reforming unit. With application of the catalyst in the tubular cell, the mixture of isooctane and air can be efficiently reformed to simple syngas (a mixture of hydrogen and carbon monoxide) at 750 °C. Compared to electrochemical performance of the single cell without the catalyst, applying the catalyst increased maximum power density of the single cell from 240 to 306 mW cm−2, and the single cell exhibited significantly improved stability during the 18 h performance test. The results suggest the feasibility of applying the NiMo‐ceria‐zirconia catalyst for operating the tubular single cell using isooctane fuel.

Words are very important to share ideas, but less is known regarding the way the message is communicated in the leadership process. The present study explored how nonverbal delivery factors might impact leaders’ charisma, followers’ mood, and followers’ performance. The research specifically focused on how immediacy and dominance impacted the relationship between leaders’ delivery styles and followers’ mood, perceptions of charismatic leadership, and performance. Results showed that immediate and dominant leadership behaviors were critical in eliciting positive mood and reducing negative mood in followers. In the absence of immediate and dominance behaviors in leaders, followers’ negative mood increased and positive mood decreased. Moreover, the dominant and immediate displays also led to higher perceptions of charismatic leadership. Crucially, only simple or mixed dominant delivery styles led to an enhancement in the performance of followers. The mediating role of followers’ positive mood on the relationship between leaders’ delivery styles and followers’ performance was also examined. More importantly, positive mood explained the link between leaders’ delivery styles and performance. Theoretical and practical implications of the role of delivery styles in the leadership process were discussed.

Numerical effects on vertical wave propagation in deep‐atmosphere models
Authors: Griffin D. J. , Thuburn J.
Published: December 2017

Ray‐tracing techniques have been used to investigate numerical effects on the propagation of acoustic and gravity waves in a non‐hydrostatic dynamical core discretized using an Arakawa C‐grid horizontal staggering of variables and a Charney–Phillips vertical staggering of variables with a semi‐implicit timestepping scheme. The space discretization places limits on resolvable wavenumbers, and redirects the group velocity and the propagation of wave energy towards the vertical. The time discretization slows the wave propagation while maintaining the group velocity direction. Wave amplitudes grow exponentially with height due to the decrease in the background density, which can cause instabilities in whole‐atmosphere models. Although molecular viscosity effectively damps the exponential growth of waves above about 150 km, additional numerical damping might be needed to prevent instabilities in the lowermost thermosphere. These results are relevant to the Met Office Unified Model, and provide insight into how the stability of the model may be improved as the model's upper boundary is raised into the thermosphere.

Published: December 2017

A new three‐dimensional Cd(II)‐organic framework [Cd(H2BDDA)]n based on fluorescent ligand, 4,4’‐([2, 2’‐bipyridine]‐6,6’‐diylbis(oxy) diphthalic acid(H4BDDA), has been successfully achieved. The obtained [Cd(H2BDDA)]n contained both fluorescent ligands and cadmium ions, thus showing multi‐responsive photoluminescence sensing properties. It can be used to detect Fe3+ with a sensitivity of 2.69 ppm in aqueous solution. For the fluorescence responses of [Cd(H2BDDA)]n dispersed in water solution with gradually increased p‐nitroaniline(p‐NA) and N‐methyl‐4‐nitroaniline (N−M‐4‐NA) concentrations, photoluminescence quenching can be detected even at a very low concentration of 0.68 ppm for p‐NA and 0.80 ppm for N−M‐4‐NA, which indicated that [Cd(H2BDDA)]n has an extremely high sensitivity to p‐NA and N−M‐4‐NA. To our best knowledge, [Cd(H2BDDA)]n is the first example of Cd(II) MOF based on the fluorescent ligand H4BDDA, which can be used for the detection of Fe3+ ions and NACs, especially for p‐NA and N−M‐4‐NA.
One‐step Preparation of Monodisperse Multifunctional Macroporous Particles through a Spontaneous Physical Process

Published: December 2017

Macroporous particles that combine the property features of spherical structures and porous materials are expected to find use over micro‐ and macroscopic length scales from miniaturized systems such as cell imaging, drug and gene delivery to industrial applications. However, the capacity for de novo design of such materials is still limited. Here, a spontaneous process to fabricate monodisperse multifunctional macroporous particles (MMMPs) by high internal phase emulsion templating is reported. An interesting physical phenomenon involving self‐emulsification and synergistic effects between nanoparticles and amphiphilic diblock copolymers is observed in this process. These MMMPs, featured with tailor‐made pore structures, pH responsiveness, and magnetic response, could be used as stimuli‐responsive carriers for multiple functional molecules with a high loading and releasing efficiency. This new understanding regarding the underlying phenomena that control self‐emulsification behavior and synergistic action in emulsion systems provides a unique outlook and a novel approach to the design of potentially multifunctional porous materials for controllable release and delivery processes.

Objective:

To determine profiles of serum ubiquitin carboxy-terminal hydrolase L1 and phosphorylated neurofilament heavy-chain, examine whether erythropoietin administration reduce their concentrations, and whether biomarkers discriminate between erythropoietin and placebo treatment groups.

Design:

Single-center, prospective observational study.

Setting:

A sub-study of the erythropoietin-traumatic brain injury clinical trial, conducted at the Alfred Hospital, Melbourne, Australia.

Patients:

Forty-four patients with moderate-to-severe traumatic brain injury.

Interventions:

Epoetin alfa 40,000 IU or 1 mL sodium chloride 0.9 as subcutaneous injection within 24 hours of traumatic brain injury.

Measurements and Main Results:

Ubiquitin carboxy-terminal hydrolase L1, phosphorylated neurofilament heavy-chain, and erythropoietin concentrations were measured in serum by enzyme-linked immunosorbent assay from D0 (within 24 hr of injury, prior to erythropoietin/vehicle administration) to D5. Biomarker concentrations were compared between injury severities, diffuse versus focal traumatic brain injury and erythropoietin or placebo treatment groups. Ubiquitin carboxy-terminal hydrolase L1 peaked at 146.0 ng/mL on D0, significantly decreased to 84.30 ng/mL on D1, and declined thereafter. Phosphorylated neurofilament heavy-chain levels were lowest at D0 and peaked on D5 at 157.9 ng/mL. D0 ubiquitin carboxy-terminal hydrolase L1 concentrations were higher in diffuse traumatic brain injury. Peak phosphorylated neurofilament heavy-chain levels on D3 and D4 correlated with Glasgow Outcome Score–Extended, predicting poor outcome. Erythropoietin did not reduce concentrations of ubiquitin carboxy-terminal hydrolase L1 or phosphorylated neurofilament heavy-chain.

Conclusions:

Serum ubiquitin carboxy-terminal hydrolase L1 and phosphorylated neurofilament heavy-chain increase after traumatic brain injury reflecting early neuronal and progressive axonal injury. Consistent with lack of improved outcome in traumatic brain injury patients treated with erythropoietin, biomarker concentrations and profiles were not affected by erythropoietin. Pharmacokinetics of erythropoietin suggest that the dose given was possibly too low to exert neuroprotection.

Published: December 2017

Background:

Vascularized composite allotransplantation is constrained by complications associated with standard immunosuppressive strategies. Vascularized thymus and bone marrow have been shown to promote prolonged graft survival in composite organ and soft-tissue vascularized composite allotransplantation models. We report development of a nonhuman primate vascularized thymosternal composite tissue transplant model as a platform to address donor-specific immune tolerance induction strategies.

Methods:

Vascularized thymosternal allograft (skin, muscle, thymus, sternal bone) was transplanted between MHC-mismatched rhesus monkeys (feasibility studies) and baboons (long-term survival studies), with end-to-side anastomoses of the donor aorta and SVC to the recipient common femoral vessels. A male allograft was transplanted to a female’s lower abdominal wall, and clinically applicable immunosuppression was given. Skin biopsies and immunological assays were completed at regular intervals, and chimerism was quantified using polymerase chain reaction specific for baboon Y chromosome.

Results:

Four allo- and 2 xenotransplants were performed, demonstrating consistent technical feasibility. In 1 baboon thymosternal allograft recipient treated with anti-CD40–based immunosuppression, loss of peripheral blood microchimerism after day 5 was observed and anticipated graft rejection at 13 days. In the second allograft, when cutaneous erythema and ecchymosis with allograft swelling was treated with anti-thymocyte globulin starting on day 6, microchimerism persisted until immunosuppression was reduced after the first month, and the allograft survived to 87 days, 1 month after cessation of immunosuppression treatment.

Conclusions:

We established both allo- and xeno- composite vascularized thymosternal transplant preclinical models, which will be useful to investigate the role of primarily vascularized donor bone marrow and thymus.
