The Colonic Pseudotumoral Form of Crohn’s Disease: About a Case at the Sourô Sanou University Hospital Center in Bobo-Dioulasso

Crohn's disease is a chronic inflammatory bowel disease (IBD) that can affect all segments of the digestive tract. For long time, it is a pathology considered to be uncommon among African blacks. It constitutes a heterogeneous group both in its etiopathogenesis and in its clinical and progressive presentation. The pseudotumoral form remains exceptional. We report a case of this form, observed in a 44-year-old patient. The pseudotumoral form of colonic Crohn's disease was diagnosed based on morphological, histological and progression criteria. This illustrates the need for multiple and repeated biopsies to eliminate malignant tumor, tuberculosis, intestinal parasitosis and other causes of digestive granulomatosis.
Removal of copper(II) from aqueous samples using natural activated hydroxyapatite sorbent produced from camel bones

A simple and low-cost procedure for the removal of copper(II) ions from contaminated aqueous samples is introduced. The method depends on the adsorption of Cu(II) ions onto a natural activated hydroxyapatite (HAP) adsorbent, simply produced by recycling camel bones food waste, then chemically and physically activated. Activated sorbent samples were characterized using FT-IR, XRD, and SEM-EDX, then initially tested for Cu(II) ions adsorption. Four samples were then selected to complete the physicochemical studies including factors affecting the adsorption efficiencies and thermodynamic studies. As a result, one sorbent sample (chemically activated sample #2) that acquired the highest adsorption efficiency among other sorbents was selected to conduct industrial semi-pilot column experiments for the treatment of copper-contaminated well-water samples. This article presents a simple method for the recycling of a major food waste and environmental pollutant in Saudi Arabia to produce an activated adsorbent that had been applied successfully in the treatment of contaminated aqueous samples.
Archive of SID The Application of Unconventional PET Tracers in Nuclear Medicine

The production and application of PET tracers has been a unique step in the progress of nuclear medicine in last two decades. The most important PET tracers include F-18, C-11 and N-13 radioisotopes and many nuclear medicine centers throughout the globe are using them. However some new tracers are under their way to the mass administration, currently being in the clinical trials or preliminary studies. Gallium-66 and 68 tracers such as Ga-DOTANOC and Ga-DOTANIC are currently being used in many neuroendocrine tumor studies in human in Europe and North America, and global application of these tracers remain to the cheaper and easier providence of 68 Ge/
Analysis, Implications, and Challenges of an Evolving Consumer IoT Security Landscape

The Internet of Things (IoT) is a rapidly growing subset of our modern computing architecture, and as such, provides significant new attack surface. The history of IoT has provided a substantial body of topics to look back on: IoT's evolution, products, and major security incidents including the largest botnet ever witnessed. Unique to IoT, its architecture, interaction design, and scale make its many issues distinct from those in the Internet of Computers (IoC). Its perceptions, understandings, and definitions have evolved over time, thus requiring an updated focus from the perspective of security and cyberphysical safety. We take a fresh look at challenges and opportunities in IoT security, the characteristics that uniquely distinguish it from the IoC, and identify security-related questions that they raise. Our aim is to provide an up-to-date view of the IoT security landscape and technical security issues to help guide both existing and especially new researchers looking for challenging open problems that remain largely unaddressed.
The Use of Collaborative Filtering , Content based Filtering and Pearson Correlation Coefficient for Multilevel Recommender System

The main objective of the study is to develop a recommendation system for movies by implementing a combination of three different algorithms: Collaborative Filtering, Content Based Filtering and Pearson Correlation Coefficient. The proposed system is a web-based application that can provide recommended movie titles based on search queries, item attributes, user historical data and user preferences. The study shows that the combination of the three algorithms is effective at n and more efficient. The combination of the implemented algorithms is not limited to providing movie recommendations alone, it can also be modified and applied on different platforms such as an e-commerce, social media, news article websites and other fields.
OO performance optimisations of HPC applications

1. High Performance Computing While many types of computer use are performance limited in one way or another the term High Performance Computing is usually used to refer to large numerical simulations (traditional supercomputing applications) where the performance is limited by the processing abilities of the computer rather than the network or disk. These simulations typically perform intense calculations on large volumes of floating point data. Traditionally the performance of HPC systems is usually measured in flops (floating point operations per second) However trends in computer architectures over recent decades now mean that the performance of this type of code is often more limited by the capabilities of the memory system than the ability of the processors to issue floating point instructions. Historically HPC applications have often been relatively simple software systems (a few 10s of thousands of lines), however the complexity of the codes has been increasing over recent years as more and more complex physical systems are simulated. This trend has been exacerbated by the introduction of compute clusters. Currently the only way of economically achieving the necessary performance for HPC applications is to distribute the applications across multiple processing nodes with independent memory systems. This adds significantly to the complexity of these codes.

Naoko Koike Tsuyoshi Otsuji Akiko Tsumura Katsuaki Miki Yukio Sakai Tetsuya Nishimura Kanji Takahashi 1Department of Ophthalmology, Kansai Medical University Medical Center, Osaka, Japan; 2Department of Ophthalmology, Kansai Medical University, Osaka, Japan Purpose: Intravitreal injection of anti-VEGF drugs has become standard therapy for patients with exudative age-related macular degeneration (AMD). However, some patients do not exhibit sufficient response to the drugs for suppression of choroidal neovascularization activity. We investigated the efficacy of switchback from ranibizumab to aflibercept in patients with AMD who could not achieve further benefit beyond initial therapy of aflibercept injection. Methods: Eleven eyes of eleven patients were included in this study. Two patients were nonresponders, and nine exhibited tachyphylaxis to aflibercept. All patients received three monthly injections of ranibizumab as an initial phase of switching and received aflibercept as a switchback drug. We investigated changes in injection interval, visual acuity, and central retinal thickness. Results: In four patients (36.4%), injection interval was extended. The interval was 6.73 weeks before switch and 9.27 weeks after switchback (P=0.96). LogMAR visual acuity was 0.22 before switch and 0.24 after switchback (P=0.62). Central retinal thickness was 306.8 μm before switch and 256.1 after switchback (P=0.13). In all patients who were nonresponders to aflibercept, injection interval could not be extended. Conclusion: A switchback from ranibizumab to aflibercept may be beneficial in some patients with AMD who exhibit tachyphylaxis to aflibercept.
Collect and Select: Semantic Alignment Metric Learning for Few-Shot Learning

Few-shot learning aims to learn latent patterns from few training examples and has shown promises in practice. However, directly calculating the distances between the query image and support image in existing methods may cause ambiguity because dominant objects can locate anywhere on images. To address this issue, this paper proposes a Semantic Alignment Metric Learning (SAML) method for few-shot learning that aligns the semantically relevant dominant objects through a ``collect-and-select'' strategy. Specifically, we first calculate a relation matrix (RM) to ``collect" the distances of each local region pairs of the $3$D tensor extracted from a query image and the mean tensor of the support images. Then, the attention technique is adapted to ``select" the semantically relevant pairs and put more weights on them. Afterwards, a multi-layer perceptron (MLP) is utilized to map the reweighted RMs to their corresponding similarity scores. Theoretical analysis demonstrates the generalization ability of SAML and gives a theoretical guarantee. Empirical results demonstrate that semantic alignment is achieved. Extensive experiments on benchmark datasets validate the strengths of the proposed approach and demonstrate that SAML significantly outperforms the current state-of-the-art methods.

Rethinking resting eggs decapsulating Repensando o decapsulamento de ovos de resistência

Aim: Temperature and light have been recognized as important factors for ephippia hatching in temperate and tropical freshwater systems. Oddly some authors suggested that decapsulation of resting eggs would be a pro when it comes to ex situ hatching studies, exposing those eggs to a greater amount of light. This study aimed to compare the difference in the hatching rate between resting eggs decapsulated and intact ephippia of Daphnia laevis, a zooplankton that occurs at lakes, in tropical freshwaters (Cladocera). Methods: The ephippia used in this work were collected at the sediment of a reservoir, in Belo Horizonte city (Minas Gerais, Brazil). We set up the laboratory experiment with two distinct groups: intact ephippia and decapsulated resting eggs. For that, we manually decapsulated 120 ephippia and kept 120 others intact (six replicas with 20 ephippia each), then incubated them all with culture water at 22oC (12h photoperiod) for 30 days with daily monitoring. Results: The results showed that decapsulation influenced negatively the hatching success, as the intact ephippia had a hatching rate of 22%, while those decapsulated only had 6%. In addition, Daphnia hatchlings were observed for intact ephippia group up to the twenty-seventh day, while for the decapsulated the last hatching occurred on the tenth day. Decapsulated eggs are subject to high exposure to light and it may jeopardize the embryo development. Conclusions: In this context, we suggest that removing the protective capsule from the eggs needs to be done with caution, since in some species this can damage the resting eggs, which alters the viability and compromise the accuracy of the hatching rates studies.
A model for freight transport chain choice in Europe

This paper describes the structure of the Transtools3 freight transport chain choice model for Europe and the data at the shipment level that were used in estimation, and presents the estimation results and resulting elasticities. It also discusses the structure of the overall freight model and how production-consumption matrices from a trade model are combined with the transport chain choice model in model application. In the estimation of the transport chain choice model on the available disaggregate data sources (the Swedish Commodity Flow Survey 2009 and the French ECHO survey) we tested several options for the specification of transport costs in the model and various nesting structures.
Cerebral schistosomiasis japonica: report of one operated case and fifty clinical cases.

Summary A study of one operated case and fifty clinical cases of the chronic form of cerebral schistosomiasis in the Kofu District of Japan during the period from 1947 to 1954 is presented. More than half of space-occupying lesions found in this District are presumed to be attributable to the chronic form of cerebral schistosomiasis. The neurologic features as well as the physical and laboratory findings in the present series are similar to those previously reported although eosinophilia was noted in the spinal fluid in one–third of the cases studied in this series. Chemotherapy with antimonial drugs is the most suitable form of treatment of cerebral schistosomiasis. The dramatic clinical effect of these drugs as well as on the eosinophilia in the spinal fluid are important corroborative elements in the diagnosis.
Evolutionary algorithms for the engine sound specification of electrical vehicles

Therefore an active influence on the interior sound is desired to provide an intuitional driver feedback and mask driving noise at the same time. However, as the electric drive train acoustically as well as technically differs strongly from drive trains based on combustion, the user acceptance is doubtful if these technologies were connected by using typical combustion engine sounds in electrical vehicles. Yet, it is not clear what these cars should sound like.
MICROFINANCE AS A POVERTY ALLEVIANT: Have we given it too Much Credit? An Analysis of Variance in Welfare Outcomes

Evaluating the effectiveness of initiatives aimed at alleviating poverty is a top priority for research in development economics. One increasingly newsworthy innovation is the concept of “microfinance”– extending small, short-term loans to poor entrepreneurs ordinarily excluded from formal financial institutions. As the logic goes, the “micro” businesses financed through this extension of credit to the poorest will generate income and catalyze growth in developing communities. This paper investigates the microfinance movement with a focus on better understanding the determinates of variance in the welfare outcomes of borrowers. Anecdotal evidence suggests that positive effects might not be universal. I utilize an in-depth survey of participants in a microfinance program based in Bangladesh to determine first what influences welfare outcomes, and second, which specific factors are linked to high variances in welfare outcomes. I find that for this particular population, initial wealth-level significantly predicts wealth growth rate, and that although inequality decreases on average, there is higher variance in the outcomes of those poorest at the baseline.
WORKING PAPER SERIES 15 310 2

A sharp increase in unemployment accompanied by a relatively muted response of inflation during the Great Recession cast further doubts on the validity of the Phillips curve. With the aid of dynamic model averaging (Raftery et al., 2010), this paper aims to highlight that the existence of a systemic relation between real activity and inflation is blurred due to (i) the failure to capture inflationary pressures by means of a single measure of economic activity, and (ii) the existence of a non-linear response of inflation to the driving variable. Based on data for the U.S. and other G7 countries, our results show that the relation between economic activity and inflation is quite sturdy when one allows for more complex assessment of the former. We find that inflation responds to different measures of economic activity across time and space, and no measure of economic activity clearly dominates. The output gap is often outperformed by unemployment-related variables such as the short-term unemployment rate, the unemployment expansion gap, and the unemployment recession gap. Finally, our results confirm a weakening of the inflation–activity relationship (i.e., a flattening of the Phillips curve) in the last decades, which might be attributed to structural changes in the economy and monetary policy, that is robust both across activity measures and across countries.

A Novel IEC 61850-Based Protection Scheme to Maintain the Generator Synchronous Operation During Power System Disturbances

This study proposes an IEC 61850 based protection scheme to maintain the generator synchronous operation and prevent its tripping by the pole slipping protection (Relay 78) during system disturbances while the transmission line distance protection (RTL) is blocked from operation. The scheme has been studied during common system disturbances, namely sudden load applications. This scheme could maintain the synchronous operation of the local generator and enable it to support the system during and after such disturbances; therefore, maintaining the system stability. A real recorded incidence of generator tripping by Relay 78 in the Egyptian grid is investigated and a new scheme to prevent such tripping during system disturbances is introduced. The new scheme takes the advantage of using IEC 61850 communication standard in coordinating the tripping role between Relay 78 and RTL. This scheme can be applied based on the current technologies of protection relays. The scheme is modeled and simulated using MATLAB Software and Xelas IEC 61850 simulator. The simulated system is configured according to the typical parameters of the Egyptian national grid 220 kV. Satisfactory results have proved the scheme effectiveness.
jSTM: JavaScript Software Transactional Memory System

This thesis proposes a JavaScript software transactional memory (jSTM) system only using features of HTML5. As web applications become widely used because of high portability, web applications become more complicated. To increase the processing speed of these applications, HTML5 supports web workers for JavaScript parallelization. However, the web worker is not perfectly suitable for parallelization because web workers do access the same memory address. In this reason, several JavaScript parallelization systems introduce transactional memory systems, but these systems need to install additional components. In contrast, with the jSTM, programmers can parallelize web applications easier than lockbased systems without installing additional components. This thesis implemented the prototype of jSTM system, and analyzed the overhead to improve the system.
Research on the Supporting of Destination Community Residents from the Perspective of Tourism Sharing

Based on the perspective of tourism sharing, this research judges the impact of tourism development for destination from the six dimensions of economy, politics, facilities, environment, culture and idea on the basis of previous studies. Fuzzy set qualitative comparison (fsQCA) method is used to explore how the residents’ perception to the six dimensions affects the local residents’ tourism and rail transport support. The results show that high level economy sharing, high level facility sharing and high level idea sharing make it easier for destination resident to generate high level tourism development support, while low level economy sharing, low level facility sharing, low level cultural sharing and low level ideal sharing are more likely to result in lower level tourism development support from local residents. In terms of rail transit support, high level economy sharing, high level facility sharing, and high level ideal sharing make it easier for local residents to generate high level rail transit support, while low level economy sharing, low level facility sharing, and low level ideal sharing are more likely to result in low level support for rail transit construction. Based on the results, this study discusses the impact of the survey results on the study of destination tourism planning and development.
THE EFFECTS OF THE SOUNDFIELD SYSTEM ON COGNITIVE PERFORMANCE OF ELEMENTARY SCHOOL CHILDREN

The purpose of this study was to analyse the effects of a Sennheiser Soundfield System on cognitive performance of school children within a classroom with average room acoustic conditions. The speech material used for the performance tests was recorded twice in the original classroom, with and without the aid of the soundfield equipment. This material was presented to the children over headphones during a laboratory experiment. This realistic simulation enabled performance data to be investigated under controlled laboratory conditions. The results show noticeable improvements of subjective speech intelligibility and working memory performance with the test material recorded through the Soundfield System. In all three performance tests, significant improvements were shown when the speech material recorded via the Soundfield System was presented. The effect seems to increase with task complexity: Within a phoneme discrimination task, improvements were noted but these were relatively small with regards to the total values obtained. Additionally, the improvement was only found with younger children. However, considerable improvements were found with both age groups for a short-term memory task (identification and storage of heard digits) as well as for a task requiring the execution of complex oral instructions (identification, storage and processing of heard sentences).

Natural treatment systems especially those based on land treatment, remain the only viable choice for wastewater treatment and reuse in small rural communities. In order to develop the appropriate technology required a slow rate (SR) systems were established at Skalani, a small village close to Iracklio, Greece. The SR systems were planted with four plant species eucalyptus, acacia, poplars and reeds to evaluate their effects on wastewater treatment and produced biomass. Systems performance were evaluated by monitoring BOD, COD, TSS, TKN, NH3-N, NO3-N, FC, and TC in soil solution and soil samples taken from the 15, 30 and 60 cm of the soil depth. The SR systems, displayed a good performance as regards COD BOD, TKN, NH3-N and bacteria removal (TC and FC). However, relatively increased values of NO3 were detected in 60 cm. In terms of plant species used, there were no significant differences in treatment efficiency among the four SR systems. Although, significant differences were observed in biomass production with acacia trees producing the greatest amount of biomass followed by reeds, while the lowest one produced by eucalyptous and poplar trees.
Preclinical Safety Evaluation Of Aqueous Bark Extract Of Saraca Asoca Roxb : Acute And Subacute Oral Toxicity

The present study was aimed to investigate the potential toxicity of the aqueous extract of the stem bark of Saraca asoca (SA) in Wistar rats following the OECD guidelines. In acute oral toxicity, female rats received a single dose of 2000 mg/kg of SA and were observed for 14 days. In sub-acute toxicity, doses of 250, 500, 1000 mg/kg/day of SA were administered to rats (males and females) for 28 days. No mortality rate was found in acute toxicity testing but some behavioural changes were recorded in animals. In sub-acute oral toxicity no significant changes in body weight, body temperature, food and water consumption and urine parameters were observed. However, significant alterations in haematological and serum biochemical parameters were noticed in animals receiving higher doses. A significant variation in relative organ weight of liver, spleen and kidney was observed in all test groups of 28 day and 90 day repeated dose oral toxicity testing. Such variation was dose dependent and hence, the present toxicity study indicates that orally administered aqueous bark extract of Saraca asoca may have some toxic effects.
