Atypical antipsychotics in the treatment of pathological aggression in children and adolescents: literature review and clinical recommendations
Authors: Teixeira Eduardo Henrique , Jacintho Antonio , Celeri Heloisa Valler , Dalgalarrondo Paulo
Published: September 2013

Objective: To review the literature about the use of atypical antipsychotics in the treatment of pathological aggression in children and adolescents. Method: The databases MEDLINE, SciELO, and LILACS were searched for publications in Portuguese or English from 1992 to August 2011 using the following keywords: mental disease, child, adolescent, treatment, atypical antipsychotic, aggressive behavior, aggression, and violent behavior. Results: Sixty-seven studies of good methodological quality and clinical interest and relevance were identified. Studies including children and adolescents were relatively limited, because few atypical antipsychotics have been approved by the Food and Drug Administration (FDA). All the medications included in this review (risperidone, olanzapine, quetiapine, ziprasidone, aripiprazole and clozapine) have some effectiveness in treating aggression in children and adolescents, and choices should be based on clinical indications and side effects. Conclusions: There are few studies about the effectiveness and safety of atypical antipsychotics for the pediatric population, and further randomized controlled studies with larger groups of patients and more diagnostic categories, such as severe conduct disorder and oppositional defiant disorder, should be conducted to confirm the results reported up to date and to evaluate the impact of long-term use.

Authors: Rutz André , Hamdan Amer Cavalheiro , Lamar Melissa
Published: September 2013

Background: Decision-making is a complex, multidimensional cognitive function that requires the choice between two or more options and also the predictive analysis of its consequences. One of the tools most widely used to assess decision-making in neuropsychological research is the Iowa Gambling Task (IGT). Objective: To conduct a systematic review of articles reporting empirical IGT studies based in Brazil. Method: Articles were obtained from multiple journal databases including ISI Web of Knowledge, Scopus, SciELO, LILACS, and Scholar Google. Results: Thirty-six studies were included in this review and divided into four categories according to main subject matter (psychiatry & personality; demographic & cultural variables; medical/clinic; and psychometric properties & test administration standardization). In general, there was a significant growth in research employing IGT (Χ² = 17.6, df = 5, p = 0.0003), but this growth was restricted to a few geographic areas of Brazil. The psychiatry & personality subject matter was the most abundant, accounting for 14 publications (39% of the total sample). Conclusion: Since its first adaptation to Brazilian Portuguese in 2006, a growing interest in decision-making as measured by the IGT can be observed, with psychiatry & personality topics representing a large portion of the scientific inquiry to date. Nevertheless, in order to extend the initial results of Brazilian IGT decision-making research, more studies are necessary - across a more diverse range of topics, including demographic & cultural variables, and psychometric properties & test administration standardization, the areas least studied -, as is the dissemination of the IGT to more regions of the country.

Objective

To examine self-reported mental health status and aggravation level in mothers of children with isolated oral clefts.

Methods

Population-based sample of children (aged 4 to 9 years) with isolated oral clefts was enumerated from births from 1998 through 2003 in Arkansas, Iowa, and New York State. Mothers of 294 children completed the Mental Health Inventory 5-item questionnaire and Aggravation in Parenting Scale. The Mental Health Inventory and Aggravation in Parenting Scale scores, stratified by poor (Mental Health Inventory ≤ 67) and better (Mental Health Inventory > 67) mental health status or high (Aggravation in Parenting Scale ≤ 11), moderate (Aggravation in Parenting Scale = 12 to 15) and low (Aggravation in Parenting Scale = 16) aggravation, were compared by selected maternal and child characteristics. Mean scores for each instrument and proportion of mothers with poor mental health or high aggravation were compared with those reported in the National Survey of American Families.

Results

Mean scores for each instrument and proportion of mothers with poor mental health or high aggravation differed little from published data. Mothers with poor mental health tended to be less educated, to have lower household incomes, and to rate their health and their child's health lower than those in better mental health. Mothers with high aggravation tended to have lower household incomes, to have more children, and to rate their health and their child's health lower than those with moderate or low aggravation.

Conclusions

Mothers of affected children were not more likely to experience poor mental health or high aggravation compared with published data; however, sociodemographic characteristics were associated with maternal psychosocial adaptation. Brief screeners for mental health and parenting administered during routine appointments may facilitate identifying at-risk caregivers.
Clearing effects on plates subjected to blast loads
Authors: Rigby Sam E. , Tyas Andrew , Bennett Terry , Warren James A. , Fay Stephen
Published: September 2013

Empirical prediction methods are often used in the early stages of design to quantify the blast load acting on a structure. While these methods are reasonably accurate for geometrically simple scenarios, they may not be accurate for situations where the target does not form a reflecting surface of effectively infinite lateral extent. In this case, the blast wave will diffract around the target edge, leading to the propagation of a relief wave inwards from the edge of the structure, reducing the late-time development of pressure in a process known as ‘clearing'. This paper presents results from a study undertaken to determine the influence of clearing on the response of simple targets. Experiments were conducted in which deflection–time histories were recorded for target plates subjected to cleared and non-cleared blast loads. These were compared with predictions from explicit dynamic finite-element and single-degree-of-freedom models, in which the blast loading was derived by applying a simple correction to the empirical blast prediction method. The results presented show that neglecting clearing may result in highly conservative predictions of target response and that analyses using loading derived from simple corrections to the ConWep predictions match the experimentally observed results very closely.

The Defence Science and Technology Laboratory sponsored, QinetiQ-led Force Protection Engineering Research Programme has two main strands, applied and underpinning research. The underpinning strand is led by Blastech Ltd. One focus of this research is into the response of geomaterials to threat loading. The programme on locally won fill is split into four main characterisation strands: high-stress (GPa) static pressure–volume; medium-rate pressure–volume (split Hopkinson bar); high-rate (flyer plate) pressure–volume; and unifying modelling research at the University of Sheffield, which has focused on developing a high-quality dataset for locally won fill in low and medium strain rates. With the test apparatus at Sheffield well-controlled tests can be conducted at both high strain rate and pseudo-static rates up to stress levels of 1 GPa. The University of Cambridge has focused on using one-dimensional shock experiments to examine high-rate pressure–volume relationships. Both establishments are examining the effect of moisture content and starting density on emergent rate effects. Blastech Ltd has been undertaking carefully controlled fragment impact experiments, within the dataspace developed by the Universities of Sheffield and Cambridge. The data from experiments are unified by the QinetiQ-led modelling team, to predict material behaviour and to derive a scalable locally won fill model for use in any situation.

Published: September 2013

A growing body of research documents the importance of plant genetic effects on arthropod community structure. However, the mechanisms underlying these effects are often unclear. Additionally, plant genetic effects have largely been quantified in common gardens, thus inflating the estimates of their importance by minimizing levels of natural variation. Using Valeriana edulis, a dioecious plant with genetically based sex determination, we conducted surveys and experiments on wild‐grown individuals to document field patterns of arthropod association between the sexes and the mechanisms underlying these plant genetic effects. Three years of surveys revealed strong and consistent sex‐biased arthropod association in wild‐grown plants: female plants supported 4‐fold, 1.5‐fold, and 4‐fold higher densities of aphids, aphid predators, and aphid‐tending ants, respectively, compared to males. There was mixed evidence that the female bias for aphids was due to higher plant quality, while we found no difference between plant sexes in aphid preference or the top‐down effects of predators and tending ants. Female bias for ants was due to both the greater attractiveness of female plants (direct effect mediated by floral nectar) and an independent, weaker effect of higher aphid abundance on females (density‐mediated indirect effect). Conversely, the female bias for predators was driven solely by the greater attractiveness of female plants. We did not find interaction modification, i.e., ant–aphid and predator–aphid interactions were equivalent between plant sexes. Plant sex explained 0.24%, 2.28%, and 4.42% of the variance in aphids, predators, and ants, respectively, values comparable to but slightly weaker than those previously reported from common‐garden studies. In contrast to the prediction of diminished plant genetic effects with increasing trophic level, we show how weak indirect effects on predators and parasitoids (via herbivores) can be complemented by strong direct effects via common plant traits (floral resources). In summary, we document direct and indirect effects of genetically based sex on a multi‐trophic arthropod community that were expressed in wild‐grown plants across multiple years.
Understanding lichen diversity on the Antarctic Peninsula using parataxonomic units as a surrogate for species richness
Authors: Casanovas Paula , Lynch Heather J. , Fagan William F. , Naveen Ron
Published: September 2013

Expert collection of specimens in the field and further determination of species is the best method for determining species richness. However, the relative paucity of botanists working in Antarctica makes this approach impractical for broad‐scale surveys of Antarctic floral biodiversity. Lichens are the dominant macrophytes of terrestrial Antarctica and, as such, play a fundamental part of the ice‐free terrestrial ecosystem. Many distinct ice‐free terrestrial habitats in the Antarctic are not represented in the current network of Antarctic protected areas. However, it is difficult to identify appropriate areas for conservation because comprehensive data on distributional patterns of Antarctic flora are not available, and existing data for most Antarctic lichen species are not compiled. Consequently, cost‐effective survey methods and surrogates for the prediction of species richness are needed to accelerate assessments of local biodiversity and help select areas for conservation. A combination of a photographic “citizen scientist” approach for the collection of data and the use of parataxonomic unit (PU) richness as a surrogate for species richness, might be a possible solution to effectively collect preliminary information and rapidly build databases on species diversity. We have developed a database and gathered photographic information on lichen occurrences for sites that are frequently visited by tourists. We tested the identification capabilities with a reference data set of Antarctic lichen images from the U.S. National Herbarium. We showed that all species used in this test can be detected and that, for 74% of the images, all classifiers were able to identify the genus of the specimen. Twenty‐nine sites were photographically surveyed by researchers and tourists between 2009/2010 and 2011/2012 in the Antarctic Peninsula region. We estimated PU richness as a proxy for species richness for each of the 29 sites surveyed and provide two examples of potential applications. These surveys provide preliminary information for identifying areas for protection and priorities for future research.

Published: September 2013

Starting up a wastewater treatment plant (WWTP) is one of the most important stages of operation. A new method was used to start Arak activated sludge WWTP up, which took in advantages of the other methods. Primarily just one of the basins was in the lane and wastewater entered the plant part by part. At first 1/30, second week 1/15, third week 1/6, and fourth week 1/3 of total inflow came to the plant. Observing little progress of biomass gain, some sludge from a similar treatment plant was added to the system, as seed. This procedure continued so the MLSS of the system, attained the 1/3 total design MLSS which was design MLSS of one basin. In the next two weeks, by using developed sludge of the self-system the second and third basins came in the lane and inflow increased to 2/3 and total flow, respectively. Finally after two months of beginning the start-up and one month after adding the seed total desired biomass was developed and the plant started to waste sludge. Because of cold weather start-up period took a longer time than expected. But even before developing biomass environment friendly results were achieved. After attaining design MLSS, BOD5 and COD removal from 40% and 60% increased to 90% and TSS removal from 70% reached to 96%. Less loading, less foam forming, no bacteriologic and chemical problems, better process control, using less seed, saving costs in sludge transport and avoiding relevant problems were the main advantages of this method.

Published: September 2013

Struvite precipitation for nutrient recovery from wastewater and sewage sludge has been attracting interest, due to the remarkable fertiliser quality of the product. A method to recover struvite from digested sludge was developed at Stuttgart University, involving first an acidic dissolution of nutrients from digested sludge followed by a precipitation step. The application was first tested in a pilot scale plant and recently upscaled to a semi-industrial size by constructing a recovery plant at a municipal wastewater treatment plant. The study reports on the technical features and the operation of the large-scale plant with a short overview on the pathway leading to the construction, as well as quality of the product.
Advancing indirect potable reuse in California
Authors: Wetterau G. D. , Chalmers R. B. , Liu P. , Pearce W.
Published: September 2013

While indirect potable reuse (IPR) has been used in southern California (USA) since the 1970s, the commissioning of the 265-megalitre-per-day Groundwater Replenishment System (GWRS) in Orange County (California) showed the region's commitment to utilizing reuse as a major source of potable water augmentation. The treatment process used at GWRS has become the benchmark on which California regulations were based and which other IPR facilities are measured against. As the cities of Los Angeles and San Diego move forward with their own IPR programs, they have commissioned pilot-scale and demonstration-scale projects to build on the lessons learned at the GWRS and to aid in developing future projects that are efficient, effective, and publicly supported. This paper will discuss the technical approaches being evaluated in these projects and the lessons learned in the operation of the existing full-scale facilities.

The Use of Shoulder Hemiarthroplasty and Humeral Head Resurfacing: A Review of Current Concepts
Authors: Widnall James C , Dheerendra Sujay K , MacFarlane Robert J , Waseem Mohammad
Published: September 2013

Since Neer’s early work in the 1950s shoulder arthroplasty has evolved as a treatment option for various glenohumeral joint disorders. Both hemiarthroplasty and total shoulder prostheses have associated problems. This has led to further work with regards to potential resurfacing, with the aim of accurately restoring native proximal humeral anatomy while preserving bone stock for later procedures if required. Hemiarthroplasty remains a valuable treatment option in the low demand patient or in the trauma setting. Additional work is required to further define the role of humeral resurfacing, with the potential for it to become the gold standard for younger patients with isolated humeral head arthritis.
An Overview of Shoulder Instability and its Management
Authors: Farrar Nicholas Greville , Malal Joby Jacob George , Fischer Jochen , Waseem Mohammed
Published: September 2013

The assessment and management of patients with instability of the shoulder joint can be challenging, due to the varying ways patients present, the array of different classification systems, the confusing terminology used and the differing potential management strategies. This review article aims to provide a clear explanation of the common concepts in shoulder instability and how they relate to the assessment and management of patients.

There are sections covering the mechanisms of shoulder stability, the clinical assessment of patients and imaging techniques. Beyond that there is a discussion on the common classifications systems used and the typical management options.

Some patients fall into reasonably well defined categories of classification and in these cases, the management plan is relatively easy to define. Unfortunately, other patients can elude simple classification and in these instances their management requires very careful consideration. Further research may help to facilitate a better understanding of management of the patients in this latter group.
The Painful Shoulder: Shoulder Impingement Syndrome
Authors: Khan Yousaf , Nagy Mathias Thomas , Malal Joby , Waseem Mohammad
Published: September 2013

Rotator cuff disorders are considered to be among the most common causes of shoulder pain and disability encountered in both primary and secondary care.

The general pathology of subacromial impingment generally relates to a chronic repetitive process in which the conjoint tendon of the rotator cuff undergoes repetitive compression and micro trauma as it passes under the coracoacromial arch. However acute traumatic injuries may also lead to this condition.

Diagnosis remains a clinical one, however advances in imaging modalities have enabled clinicians to have an increased understanding of the pathological process. Ultrasound scanning appears to be a justifiable and cost effective assessment tool following plain radiographs in the assessment of shoulder impingment, with MRI scans being reserved for more complex cases.

A period of observed conservative management including the use of NSAIDs, physiotherapy with or without the use of subacromial steroid injections is a well-established and accepted practice. However, in young patients or following any traumatic injury to the rotator cuff, surgery should be considered early. If surgery is to be performed this should be done arthroscopically and in the case of complete rotator cuff rupture the tendon should be repaired where possible.

Professor Grammont revolutionised shoulder surgery with his reverse shoulder arthroplasty design. Patients who had poor results from a conventional shoulder replacement because of cuff deficiency can now be treated effectively. Although designed for cuff tear arthropathy, indications continue to evolve and broaden. The initial results look very promising and the implant has gained much popularity over the years. The article provides an extensive literature review of the indications, results and complications for reverse shoulder arthroplasty.
The Private Foundation Minimum Distribution Requirement and Public Policy
Authors: Levine Carolyn B. , Sansing Richard C.
Published: September 2013

This study examines the public policy rationale for the minimum distribution requirement that requires private foundations to spend at least 5 percent of their assets on charitable purposes. The study explicitly models an objective function that the government tries to maximize and a population of heterogeneous contributors that care about both distributions to charity and assets under their control. An increase in the minimum distribution requirement increases the rate of charitable distributions from some foundations, but deters other contributors from forming foundations. The level of the minimum distribution requirement reflects a trade-off between these two effects.
Phase Reactions During Sintering of M3/2 Based Composites with WC Additions
Authors: Madej M.
Published: September 2013

Attempts have been made to describe the influence of WC additions on properties of M3/2 high speed steel (HSS) based composites. The powder compositions used to produce skeletons for further infiltration were M3/2, M3/2+10%WC and M3/2+30%WC. The powders were cold pressed at 800 MPa. The green compacts were subsequently sintered for 60 minutes at 1150°C in vacuum. These as-sintered specimens were used for copper infiltration. A qualitative EDX analysis revealed presence of both MC type vanadium-rich carbides and M6C type tungsten and iron rich carbides. In specimens containing 10 and 30% WC the carbide phase was uniformly distributed within copper-rich regions. The WC monocarbide reacts with the surrounding HSS matrix and forms a carbide grain boundary film. The microstructural observations of the as-sintered specimens was followed by Brinell hardness test and supplemented with dilatometric studies.
Globular Microstructure Formation in X210CrW12 Steel for Semi Solid Processing Using Plastic Deformation or Boron Modification
Authors: Rogal Ł. , Dutkiewicz J.
Published: September 2013

Semi-solid processing (SSP) belongs to advance method of forming metal alloys in the solidus-liquidus range. Such technology requires a fine globular microstructure in a semi-solid range, which can be produced by numerous methods. The present paper focuses on two methods of preparation of a globular microstructure in X210CrW12 tool steel as a possible way of preparation of feedstock for thixoforming: hot plastic deformation (SIMA), and modification with boron. DSC analysis allowed to establish the amount of liquid phase fraction vs temperature. Samples were heated up to the semi-solid temperature range - 1230°C, which corresponds to 17% (SIMA) and 30% (modified) of the liquid fraction. Then they were rapidly cooled. The obtained microstructures of samples were investigated for their suitability for SSP. The microstructure of X210CrW12 steel prepared by SIMA shows a globular microstructure with average grain size 57 μm. The samples after modification with 0.08% (weight pct) boron also feature a globular microstructure with the size of 46 μm. The grains possess an austenitic structure and are surrounded by an eutectic mixture

Published: September 2013

Hardness, microstructure and abrasive wear resistance of cast high-manganese steel (cast Hadfield steel) were compared with the cast steel of the same austenitic matrix but having vanadium carbides uniformly distributed within its entire volume. The chemical composition of the cast steel was chosen in such a way as to produce a composite structure after the alloy solidification. A similar hardness of the matrix was obtained with carbides evenly distributed in it, while abrasive wear resistance doubled its value. Using the investment casting process, working elements of teeth for the excavators and mechanical coal miners were cast.

Authors: Holtzer M. , Żymankowska-Kumon S. , Kubecki M. , Kwaśniewska-Królikowska D.
Published: September 2013

The assessment of harmfulness of two resins applied as a partial substitute of coal dust in moulding sands with bentonite - was performed in the paper. The emission value of compounds from the PAH and BTEX groups was assumed as the main harmfulness criterion. Also mixtures of the Kormix type prepared with additions of these resins were tested. Experiments were carried out in an argon atmosphere in a temperature range: 500-1300°. The obtained emission values of these substances were recalculated for 1% of lustrous carbon content in each carrier. It was assumed in the calculations, that the NW 1 and NW 2 carriers contain approximately 55% of lustrous carbon while the Kormix mixture approximately 15%. The critical temperature of forming compounds of the PAH group for the NW 1 carrier is 900°, while for the NW 2 carrier is 1100° (this is a temperature, at which the emission abruptly increases). In case of formation of compounds from the BTEX group the critical temperature for both lustrous carbon carriers is a temperature of 900°.
Heat Exchange in the System Mould – Riser – Ambient. Part I: Heat Exchange Coefficient from Mould External Surface
Authors: Krajewski P.K. , Zovko-Brodarac Z. , Krajewski W.K.
Published: September 2013

The subject of the paper is heat exchange in the system casting - riser - ambient. The examinations were focused on evaluating temperature dependence of the coefficient of heat exchange from mould external surface (or from riser thermally insulated surface) to ambient. The examinations were carried out for the surface temperatures of 200-800°. On the basis of the performed examinations it was stated that the relationship αext:eff vs. surface temperature can be described by a polynomial of 3rd degree with accuracy of 90-95% and that the αext:eff coefficient significantly depends on the examined material mass density.
Modeling of Self-Induced Vibrations that Occur During the Machining Process of Casting Patterns with the Use of The Fuzzy-Neural Networks Method
Authors: Herberg A.
Published: September 2013

This article outlines a methodology of modeling self-induced vibrations that occur in the course of machining of metal objects, i.e. when shaping casting patterns on CNC machining centers. The modeling process presented here is based on an algorithm that makes use of local model fuzzy-neural networks. The algorithm falls back on the advantages of fuzzy systems with Takagi-Sugeno-Kanga (TSK) consequences and neural networks with auxiliary modules that help optimize and shorten the time needed to identify the best possible network structure.

The modeling of self-induced vibrations allows analyzing how the vibrations come into being. This in turn makes it possible to develop effective ways of eliminating these vibrations and, ultimately, designing a practical control system that would dispose of the vibrations altogether.
Dynamic Behaviour of a Vibrating Jaw Crusher for Disintegration of Hard Materials
Authors: Wolny S.
Published: September 2013

One of the trends in design solutions of crushers ensuring the crushing ratio of about 30 involves the application of the vibratory-impulse action to the material to be crushed. Crushers utilising these effects are referred to as vibratory crushers. During the vibratory crushing the material to be disintegrated is subjected to the action of fast changing shearing forces, which leads to the material being crushed either by applied impulses or by fatigue action, unlike conventional crushers where the structure of the material is damaged by the applied pressure.

A dynamic analysis of the vibrating jaw crusher operation is provided and its potential application to crushing hard materials, such as alloy materials containing iron and slag from metallurgical processes are explored.
Manganese Influence on Chromium Distribution in High-Chromium Cast Irons
Authors: Byelikov S. , Volchok I. , Netrebko V.
Published: September 2013

It is shown that chromium distribution in the metal base of high-chromium cast irons depends on manganese content. According to the X-ray micro-spectral analysis data with the increase of manganese content from 0.72 to 6.49% chromium content decreased in the near-carbide zones. At the same time chromium content in carbides increased. This process obtained particularly strong development inside eutectic colonies of carbides. As a result of it, when total chromium content in the alloy has been 23%, its concentration in the local zones was 12,3%, thus the necessary level of corrosion resistance has not been provided. The minimal chromium content has to amount 23.2%, at 6.49% Mn and 2.2...2.5% C in order to provide corrosion resistance of high-chromium cast irons

Published: September 2013

This paper presents assumptions for a system of automatic cataloging and semantic text documents searching. As an example, a document repository for metals processing technology was used. The system by using ontological model provides the user with a new approach to the exploration of database resources - easier and more intuitive information search. In the current document storage systems, searching is often based only on keywords and descriptions created manually by the system administrator. The use of text mining methods, especially latent semantic indexing, allows automatic clustering of documents with respect to their content. The result of this clustering is integrated with the ontological model, making navigation through documents resources intuitive and does not require the manual creation of directories. Such an approach seems to be particularly useful in a situation where we are dealing with large repositories of unstructured documents from such sources as the Internet. This situation is very typical for cases of searching information and knowledge in the area of metallurgy, for example with regard to innovation and non-traditional suppliers of materials and equipment.
Computer Control the Cooling Process in Permanent Mold Casting of Al-Si Alloy
Authors: Władysiak R.
Published: September 2013

The paper presents the test results of a computerized control system the sequential cooling process of permanent mold with use of water mist in the gravity die casting process.

It describes the process for preparing high-quality casts made of AlSi7Mg alloy that achieves enhanced mechanical properties. A scheme of developed device and drivers for selected methods of sequence cooling for manufacturing of castings made in permanent steel mold was presented here. Also the microstructure and mechanical properties of received aluminium casts were described. It was shown that the use of a computer system to control the water mist cooling point of the mold not only accelerates the cooling of the cast and the gravity die casting cycle shortens, but also it has a positive effect on the microstructure and mechanical properties of castings made of unmodified AlSi7Mg alloy in a raw state.

Published: September 2013

The morphological characteristics at the level of the bifurcation of the common carotid artery were studied on 46 cases, finding that the most frequent, in 52.17% of cases, the common carotid bifurcation appear as the letter “V”, with two possible variations: a wide “V”, in 43.48% of cases and narrow “V” in 8.7% of cases. In 30.43% of cases, the two carotids showed an ascending traject, united for 1-2 cm up to their crossing; in 13,04% of the cases the two arteries were superimposed, the external located anteriorly. In only in two cases on the right side (4.35% of cases and 8.33% of right samples) we found a peculiar aspect of a “U” shaped bifurcation. Regarding the caliber of the external carotid artery, we found that in 43.33% of the cases the external carotid artery had a similar diameter to the internal carotid, also in 43.33% of the external carotid artery have a higher caliber than internal one and the remaining 13.33% of the cases, the external carotid artery had a smaller diameter than the internal one, with all cases on the left (16.67% of left carotid arteries). The caliber of the right external carotid artery was between 4 to 5.6 mm and the one of the left was between 3.6 to 5 mm. When the external carotid was more voluminous than the internal, the differences were 0.5 to 1.2 mm and when the internal carotid was more voluminous than the external, the differences were smaller, 0.2 to 0.8 mm. In relation to the common carotid, the external carotid had a smaller caliber from 0.6 to 1.1 mm. Regarding the external carotid traject, most commonly, from the bifurcation of the common carotid, the external carotid artery showed a vertical trajectory, in 50% of cases; in 40% of cases, the traject was oblique superomedially and in 6.67% of cases the external carotid artery described a curve with the convexity facing laterally, with all cases on the right (11.76% of right carotid arteries); in 3.33% of cases, both on the left (7.69% of the left carotid arteries), the external carotid artery traject described an inverted italic “S”

It is widely known the need for a high quality sedation associated with local regional anesthesia in elderly patients’ surgery. The aim of this study was to compare two sedation regimes: propofol and midazolam, associated to spinal anesthesia with isobaric 0.5% bupivacaine in lower abdominal surgery in elderly patients. After obtaining the informed consent, 60 patients aged between 65 and 82 years old (ASA I-III), scheduled for unilateral hernioplasty , under spinal anesthesia with isobaric bupivacaine 1,5 ml (0.5%), were randomized into two groups of 30 patients each: P group - patients received propofol 3mg/kg/body/hour in the first 10 minutes and then continuous infusion by injection of 1,8 mg/kg/body/hour, and group M-patients who have received midazolam 0,2mg/kg/body/hour in the first 10 minutes and then continuous infusion by injection of 0,15 mg/kg/body/hour. In order to achieve a similar level of sedation we used 0,1% midazolam infusion and 1% propofol. Intraoperative, the following have been monitored: heart rate and breath, mean arterial pressure, hemoglobin oxygen saturation. We have also recorded the sedation score (modified Wilson sedation scale), awakening times, patient satisfaction at 24 hours (satisfaction score according to Iowa University). The average score of sedation for group P was of 3,24 ± 0,23, compared to 2,64 ±0,42 in group M (p = 0.001). Both drugs reduce blood pressure, but not more than 20% of the initial value. There are no significant differences in the satisfaction score of the patient (p = 0,18). There was just one case of respiratory depression in group M with the decrease of SpO2 at 86%.Sedation with propofol associated with local regional anesthesia techniques in elderly patients seems to provide better conditions in terms of sedation score and lack of

respiratory depression compared with the administration of midazolam. Recovery was significantly faster after sedation with propofol. The satisfaction score of the patient was similar in the two groups

To effectively produce clean heat energy from biomass, microwave (mw) pre-processing of its different types - pelletized wood (spruce), herbaceous biomass (reed canary grass) and their mixture (50:50) - was carried out at the 2.45 GHz frequency with different durations of biomass exposure to high-frequency oscillations. To estimate the mw pre-processing effect on the structure, composition and fuel characteristics of biomass, its thermogravimetric (TG), infrared spectroscopy (FTIR) measurements and elemental analysis were made. The pre-processing is shown to enhance the release of moisture and low-calorific volatiles and the partial destruction of biomass constituents (hemicelluloses, cellulose), promoting variations in the elemental composition and heating values of biomass. The field-enhanced variations of biomass characteristics and their influence on its gasification and combustion were studied using an integrated system of a biomass gasifier and a combustor with swirl-enhanced stabilization of the flame reaction zone. The results show that the mw pre-processing of biomass pellets provides a faster weight loss at the gasification, and, therefore, faster ignition and combustion of the activated pellets along with increased output of heat energy at their burnout

The ischemic stroke is one of the most common conditions in our hospitals, representing 50% of revenues of neurology services. A variety of processes is cerebral ischemic myocardial cerebellum. Cerebellar infarction is not a rare disease, representing between 2 to 4% of all cerebrovascular events in clinical and autopsy series, and their ratio is 4-5 times higher than cerebellar hemorrhage. Although it is increasingly documented, it rarely Recognized stills like a phenomenon. Mutism occurs primarily in children and occasionally in adults as a well-recognized complication of posterior fossa surgery. Rarely been reported transient mutism associated with cerebellar infarction as isolated episode
Telomerase and its extracurricular activities

The classical activity of telomerase is to synthesize telomeric repeats and thus maintain telomere length, which in turn ensures chromosome stability and cellular proliferation. However, there is growing evidence that implicates telomerase in many other functions that are independent of TERC being used as its template. Telomerase has an RNA-dependent RNA polymerase (RdRP) activity in the mitochondria. Other than viral RdRPs, it is the only RNA-dependent RNA polymerase that has been identified in mammals. It also plays a role in the Wnt signaling pathway by acting as a transcriptional modulator. Telomerase acts as a reverse transcriptase independent of its core subunit, TERC. Studies indicate that telomerase is also involved in apoptosis and DNA repair.
Production and application of amylases of Rhizopus oryzae and Rhizopus microsporus var. oligosporus from industrial waste in acquisition of glucose

Published: September 2013

Amylases from Rhizopus oryzae and Rhizopus microsporus var. oligosporus were obtained using agro-industrial wastes as substrates in submerged batch cultures. The enzymatic complex was partially characterised for use in the production of glucose syrup. Type II wheat flour proved better than cassava bagasse as sole carbon source for amylase production. The optimum fermentation condition for both microorganisms was 96 hours at 30°C and the amylase thus produced was used for starch hydrolysis. The product of the enzymatic hydrolysis indicated that the enzyme obtained was glucoamylase, only glucose as final product was attained for both microorganisms. R. oligosporus was of greater interest than R. oryzae for amylase production, taking into account enzyme activity, cultivation time, thermal stability and pH range. Glucose syrup was produced using concentrated enzyme and 100 g L−1 starch in a 4 hours reaction at 50°C. The bioprocess studied can contribute to fungus glucoamylase production and application.
Labeling of genetically modified food: Closer to reality in the United States?
Authors: Wohlers Anton E.
Published: September 2013

Within the broader context of several related biotech developments, including the proliferation of GM food in American grocery stories, the recent decision by Whole Foods Market, Inc. to require the labeling of all genetically modified (GM) organism products sold in its stores by 2018, and the development of GM animals for consumption, this essay asks whether the United States is inching towards a policy of mandatory GM food labeling. The analysis highlights aspects of the biotechnology policy debate in the United States and European Union, and traces public opinion as well as grassroots and legislative efforts aimed at GM food labeling. Findings show that activities at the federal level do not suggest any major regulatory changes regarding labeling in the near future; however, a growing number of individual states are considering GM food labeling legislation and political momentum in favor of labeling has picked up in recent years. Voluntary labeling by food companies may also become increasingly common.

Published: September 2013

This article reviews research on the effectiveness of four categories of intervention when implemented in public schools with adolescents and young adults diagnosed with an autism spectrum disorder. The study’s inclusionary criteria include a setting of public schools, participants aged between 12 and 22 years, and the investigation of an antecedent-, consequence-, self-management-, or video-based intervention strategy to influence skills or behaviors in students. A total of 34 studies met these criteria. The procedures of the What Works Clearinghouse Standards for Single-Case Designs and Evidence are used to evaluate whether sufficient high-quality research in using antecedent-, consequence-, self-management-, and video-based strategies exists to consider these evidence-based practices. Intervention effectiveness is estimated using PAND scores and phi coefficients. The results suggest that sufficient research exists to consider antecedent-, video-, and consequence-based interventions evidence-based practices for adolescents and young adults in public schools. The need for more applied research with adolescents and young adults is highlighted.

The issues of professional accountability, faculty member development, and enhancing higher education quality in universities are gaining importance. A strategy that could increase personal control over teaching practices in addition to improving professional development among faculty members is peer review of teaching (PRT). Five themes that are important in determining the feasibility of PRT are (a) benefits of peer review in developing faculty members, (b) barriers to peer review of teaching, (c) gaps in literature, (d) potential problems to teaching practice, and (e) opportunities. Of the 65 studies identified, 34 were selected for further analysis, and drawing on PRT and the SWOT (strength, weakness, opportunity, and threat) framework, 27 studies were selected for content mapping. Textual narrative synthesis was used to further categorize the review findings into the four quadrants of the SWOT framework. This analysis highlights a positive strategy in promoting PRT in higher education.
