In detecting deception using Decision Tree and SVM across different cues
Authors: Owolafe O. , Ayeni A.O.
Published: May 2022

Past and present researches in deception detection make use of questioning to ascertain the truth and deceit in the response of the interviewee. In such questioning method, either the verbal or nonverbal cues are closely monitored and analysed to arrive at a decision. Since no single verbal or nonverbal cue is able to reliably detect deception the research proposes to use both the verbal and nonverbal cues to detect deception. Therefore, this research aims to develop a Support Vector Machine and Decision Tree Model to classify the extracted verbal, nonverbal and VerbNon features as deceptive or truthful. The verbal cues capture the speech of the suspect while the nonverbal cues capture the facial expressions of the suspect. The Praat (a tool for speech analysis) was used in extracting all the verbal cues while the nonverbal features were extracted using the Active Shape Model (ASM). The work was implemented in 2015a MatLab. The analysis of the result shows that Decision Tree performs better than SVM in the classification with a percentage score of 93.5% for Nonverbal cues as against that of SVM having percentage score of 91.9%. For verbal and VerbNon cues, Decision Tree recorded 89.9% and 97.6% accuracy while SVM recorded 89.2% and 97.1% accuracy.

This work presents the effect of orientation angles and boundary conditions on the pure bending coefficient of thin rectangular laminated composite plates using Euler-Bernoulli equilibrium equation. The total potential energy function was applied assuming that the thin rectangular laminated composite plate was subjected to only pure bending effect, through this means, the Euler-Bernoulli governing equation of equilibrium was obtained. The governing Equation obtained was minimized to obtain Equation for obtaining the pure bending coefficient of thin rectangular laminated composite plate. Different orientation angles of laminas and boundary conditions were considered to know their effect on pure bending coefficient. Some of the plate boundary condition considered were SSSS, CCCC SSCC and SCSC. The orientation angles considered were 0000, 00900, 000000, 0090000, 00000000, and 0090090000. The aspect ratio considered ranges from 1-2 for elastic modular ratio E1/E2 = 25; G12/E2 = 0.5; V12 = 0.25. For any laminated composite plate considered, the orthotropic plate has the same pure bending coefficients but the value increases with increase in the aspect ratio. When other orientations were considered, the change in orientation angles produces change in the pure bending coefficient which increases with increase in aspect ratio. The maximum pure bending coefficient was obtained when SSSS thin rectangular laminated composite Plate was considered for two laminas with orientation 00900 as 0.0174 while the minimum pure bending coefficient was obtained when CCCC thin laminate composite plate was considered for orthotropic plate as 0.00153.
Effects of supplemental bee pollen on performance, meat quality, serum constituents and immunity system in growing quails
Authors: Sevim Behlül
Published: May 2022

This study focused on the effects of adding various levels of bee pollen to diets for Japanese quail (Coturnix coturnix Japonica). The response variables that were examined included their performance, carcass characteristics, meat colour, immune system, and some serum constituents. A total of 160 one-day-old quail chicks were used. These chicks were randomly assigned to four treatments, each consisting of 40 chicks. These groups were further divided into four replicates of ten birds. The treatments consisted of diets to which 0.0, 2.5, 5.0, and 10 g/kg bee pollen were added. The feeding period lasted 42 days. The performance and serum biochemistry of the growing quails were not affected by the addition of bee pollen to the diet. The addition of 5 g/kg bee pollen increased the follicle weight and the L* value of the breast, and decreased the a* value of the thigh. It also improved the serum immunoglobulin A (IgA) content. Thus, the addition of 5 g/kg bee pollen to the diet of growing quails was effective in improving follicle development, meat quality and immune system.

Published: May 2022

The Culicidae family has two of the most important disease vector genus: Aedes spp. and Culex spp. Both of these are involved in the transmission of arboviruses. Here, we provide novel data for the geographical distribution of 2,383 specimens in the Culicidae family. We also report the percentage of houses infested with these vectors, and Shannon and Simpson diversity indices in three municipalities located in Cauca, Colombia. This dataset is relevant for research on vector-borne diseases because Aedes spp. can transmit arboviruses such as dengue, Zika and chikungunya, and Culex spp. is a well-known vector of West Nile virus and Venezuelan equine encephalitis.

Le principe de la légalité criminelle dans l’africanisation de la justice pénale internationale
Authors: FOTSING TAKAM Serges Roméo
Published: May 2022

Les désaccords entre une partie de l’Afrique et la Cour pénale internationale concernant la politique criminelle afro-centriste de cette dernière ont contribué à la mise en place, par l’Union africaine, des instruments d’adaptation africaine de la justice pénale internationale. Cette adaptation autrement appelée « africanisation » nécessite de tenir compte des principes fondamentaux de la matière pénale. Au rang desdits principes figure la légalité criminelle. La présente réflexion a justement pour objet la prise en compte de cette dernière par l’Organisation panafricaine. Elle interroge la manière dont le principe de la légalité criminelle est intégré dans le processus actuel de régionalisation africaine de la justice pénale internationale. Dans ce sillage, elle met en exergue la relativité d’une telle intégration. En effet, une analyse de la question révèle une prise en compte aussi bien consistante qu’insuffisante du principe. Dès lors, il s’avère urgent de combler les insuffisances décelées, car l’efficacité de la répression régionale africaine des crimes internationaux commis sur le continent noir en dépend. C’est, semble-t-il, l’un des enjeux de la régulation pénale contemporaine des rapports sociaux en Afrique.
Le droit pénal dans le système africain de protection des droits humains
Authors: MBOUMEGNE DZESSEU Serges Frédéric
Published: May 2022

La législation africaine, en amont et en aval du système africain de protection des droits de l’homme, a, à travers le cadre juridique relatif à la Cour et à la Commission africaines, donné compétence incidente pour se prononcer sur des questions de droit pénal dans le contentieux international des droits de l’homme. Les infractions à la loi pénale de procédure et la loi pénale de fond abondent dans la jurisprudence de la Cour africaine des droits de l’homme et des peuples. Ce dernier prépare ainsi le passage à la future Cour africaine de justice, des droits de l’homme et des peuples dont les compétences sont étendues aux crimes internationaux relevant du droit international pénal. Cette contribution a eu le mérite de mettre en exergue les germes réels du droit pénal de forme et de fond dans les décisions de la Cour et de la Commission africaines. Elle montre qu’il s’agissait des prémisses vers une future Cour africaine de justice, des droits de l’homme et des peuples comportant une section du droit international pénal dont le but est d’asseoir la compétence pénale de la juridiction régionale dans un dynamisme structurel avec l’apparition d’un Procureur poursuivant.
La détermination du nouveau régime des contraventions par voie réglementaire : une délégation ou une délégalisation de la compétence?
Authors: CHAKOUNTÉ NJAMEN Stella
Published: May 2022

Les comportements contraventionnels ont-ils été qualifiés et sanctionnés par décret n° 2016/319 du 12 juillet 2016 en vertu d’une compétence qui est propre à l’autorité réglementaire ou qui lui a été consentie par l’autorité législative? La question n’est pas nouvelle. Mais la réforme du Code pénal camerounais opérée le 12 juillet 2016 lui donne, plus que par le passé, un retentissement nouveau. La Constitution du Cameroun (préambule et articles 26, 27), la jurisprudence et la doctrine (les pessimistes et les optimistes) n’étaient pas unanimes sur la question. Désormais, trois détails de la réforme ne peuvent plus être ignorés, notamment les dispositions des articles 1 (c), 17 et 362 de la nouvelle loi n° 2016/007 portant Code pénal dont le titre 4 du livre 2 précise que les dispositions des articles 362 à 370 définissant les contraventions sont fixées par voie réglementaire. Menée à l’aide de l’exégèse, de la dogmatique, de la casuistique et de la méthode comparative, l’analyse révèle que la délégalisation est limitée au régime d’incrimination des contraventions. Seul le régime des sanctions reste attribué au Parlement qui est libre de le déléguer. Cette délégation est par ailleurs nécessaire, car la sanction est le corollaire de l’incrimination.
Application of UIC 421 procedure to Freight Trains fitted with a Distribute Power System
Authors:   University of Rome ", Cantone Luciano ,   Tor Vergata",   , ITALY
Published: May 2022

Within the Innovative Programme 5 (IP5) of Shift 2 Rail (S2R) initiative (“Moving European Railway Forward”), The Open Call Project, Marathon2Operation (M2O), has cooperated with the FR8RAIL II Project to demonstrate the feasibility of freight trains equipped with Distributed Power System (DPS), using wireless communication to control the Traction Units (TUs). At this aim, the TrainDy software has been used as computational tool for Longitudinal Train Dynamics (LTD) and the Leaflet UIC 421 was applied as methodology in order to compare simulation results. The TrainDy software is considered the state-of-the-art tool for LTD computation by major European Railway Undertakings and the Leaflet UIC 421 provides a statistical methodology to accept new or modified operational scenarios for freight trains, which are beyond current regulations in terms of hauled mass and/or train length. The basic idea of UIC 421 is the “relative approach”, even if it does not discard the “absolute approach”. In short, the “relative approach” considers a train acceptable for regular operation if the risk level of the train is lower than the risk level of trains already in service; “the absolute approach” considers a train acceptable for regular operation if in-train forces are lower than (reliably) computed or measured admissible in-train forces. Since the cooperation among M2O and FR8RAIL II was based on the “relative approach”, only this approach will be discussed in this paper. The computation of in-train forces is crucial for new train consists to avoid derailment or disruption.

The paper shows the application of the relative approach in a particular way: the same trains (randomly generated) are simulated with and without the DPS system, considering different train operations and assuming communication among the TUs successful or not. In this way, the effects on in-train forces of DPS and wireless communication are immediately emphasized.

This paper reports the comparison between experimental measurements and TrainDy simulations and a series of analyses performed to compare the LTD of reference train against DPS train on level track, but also on up/down hill. The interesting conclusion that comes from this study is that the comparison among the reference and DPS trains does not depend on the track gradient, but rather on the train operations. Of course, the track gradient, especially when it is as steep as the one considered in this analysis, has a considerable effect on in-train forces as well as the exact train configuration (i.e., the wagon order within the train).

This paper could be used as guideline for similar analyses about in-train forces of new types of trainsets, e.g., implementing a new technology as radio DPS.
Topology Optimisation of an Automotive Disc Brake Rotor to Improve Thermal Performance and Minimise Weight.
Authors:   University of Leeds, UNITED KINGDOM, Oshinibosi Ahmed , Barton David , Brooks Peter , Gilkeson Carl
Published: May 2022

Weight reduction has become a major topic in the automotive industry due to the environmental impacts of carbon emissions. When considering the thermal performance of disc brake rotors, it is increasingly important to optimise their design in a weight-efficient manner. With the advent of electric vehicles, which are heavy due to battery requirements, there is even more impetus to reduce total vehicle mass which can extend driving range. Furthermore, the brake disc constitutes part of the vehicle’s unsprung mass, so minimising brake rotor weight helps to improve ride comfort and reduce damage to the road surface. Considering thermal performance, the temperature rise produced by friction at the sliding interface leads to thermo-elastic deformation within the disc. Consequently, this can change the distribution of contact pressure and cause thermal localisation such as hot-banding and hot-spotting. The phenomenon is called thermo-elastic instability, and if severe, this can cause judder, as well as decrease the fatigue life of the disc. This paper introduces topology optimisation in the development of a ventilated brake disc used on a high performance passenger vehicle with the aim of improving thermal performance, while minimising mass. A baseline ground structure is formulated to enable new conceptual vane geometries for both improved thermal performance and lower disc mass to be derived. This approach allows novel disc designs not previously considered to evolve. Although possibly more difficult to manufacture than the conventional disc, the potential performance benefits of this more radical optimisation strategy are clearly demonstrated. Furthermore, CFD analysis is utilised to predict the air flow through the conceptual vane designs produced from the topology optimisation process. This allows for estimation of convective heat transfer coefficient for the novel design concepts and enables detailed flow patterns within the vane geometries to be predicted.
Braking Curves in Railway Shunting and Implications for the Development of Sensor Systems for Autonomous Shunting
Authors:   FH Aachen University of Applied Sciences, GERMANY, Blumenschein Matthias ,   FH Aachen, GERMANY, Pfaff Raphael , Babilon Katharina
Published: May 2022

Shunting operations differ largely from train operation on the mainline in both train protection and braking. While for mainline operations, braking of all axles in a train set is mandatory under most circumstances and unbraked wagons and axles are an exception, common shunting regulations allow for up to 40 unbraked axles depending on the locomotive mass and track gradient. On the other hand, train protection in shunting operation is mostly achieved on an on sight basis, which means that no technical devices ensure the freedom of movement. It is rather common to discuss automatic train operation (ATO) these days, however most discussions focus on the mainline portion of freight rail. In mainline operation however, the movement authority is ensured by signalling, so no long range scanning equipment, such as cameras, radar and LiDAR is strictly required to ensure safety of operation. Also, based on the braking behaviour of the train in question, a rather precise velocity recommendation is provided, either by static signals (brake tables, signage) or by continuous communication (e.g. LZB, ETCS). The opposite holds true for shunting: in most cases, a movement authority is not given or ensured by technical means, rather the observation of the shunting area by the driver and potential assistants check whether the intended track is free and safe. At the same time, the braking behaviour of the shunting groups is not precisely known and predicted by the driver based on instinct and experience. For this reason, to assist and eventually replace the aging workforce of shunting drivers and shunting assistants, a perception system is considered more demanding since it cannot rely on ATP infrastructure as in the mainline case. In this paper, the special brake setup for shunting mode is analysed and braking curves for numerous cases, ranging from an individual locomotive using direct brake only to a train consist with the maximum number of unbraked axles, are simulated. The simulation software takes into account the train setup, braked weight and brake mode as well as variations in the loading state and the friction and adhesion parameters. The corresponding braking distances are inspected and put into relation to common track geometries and use cases in shunting areas. Further, the visibility requirements from the respective European regulations are reviewed based on these use cases. The requirement set made up of track geometries, visibility and the respective braking curves provides the input for the generation of a set of requirements for the development of a perception system for shunting operation. Example data from current tests of a candidate sensor system will be shown.

Published: May 2022

This study investigates the combination of finite difference method (FDM) and the stabilized Lanczos method to solve various partial differential equation (PDE) problems. This combination is wrapped in the algorithms called hybrid FDMRMEIEMLA and hybrid FDM-RLMinRes. FDM is the discretization method which converts the PDEs into algebraic formula, whereas both RMEIEMLA and RLMinRes are known as the stabilized Lanczos methods in solving largescale problems of SLEs. Their hybrids enable us to find the solutions of PDE problems accurately. There are at least three types of PDEs solved in this study, namely Helmholtz, wave, and heat equations. The convergence rate of our methods computed using the residual norms || b - Axk ||. Numerical results showed that our proposed methods performed well in solving the various PDEs with small residual norms.

Published: May 2022

This article is devoted to the construction and study of the exponential stability of an explicit upwind difference scheme for a mixed problem for the linear system of the Saint Venant equation. For the numerical solution of the mixed problem for the linear system of the Saint Venant equation, an explicit upwind difference scheme is constructed. For a numerical solution, a discrete Lyapunov function is constructed and an a priori estimate for it is obtained. On the basis of the discrete Lyapunov function, the exponential stability of the numerical solution of the initial-boundary-value difference problem of the mixed problem for the linear system of the Saint Venantequation is proved. A theorem on the exponential stability of the numerical solution of the initial-boundary-value difference problem is proved. The behavior of the discrete Lyapunov function is numerically investigated depending on the algebraic condition of exponential stability of the numerical solution of the mixed problem. The results of the theorem on the exponential stability of the numerical solution are confirmed by a specific example of an open channel flow problem.

Using the third party for cartel facilitation is not a rare situation and represents a logical trial of cartel participants to hide their illicit activities. But the case of unilateral initiative and related action of a third party undertaken in implementation of that initiative resulting in creating a cartel(like situation) on clients’ market in order to achieve its own legally unallowable objectives is rather unique but in today’s market existent phenomenon. This situation is a factual ground in two cases resolved by Court of European Union namely: Eturas and VM Remonts. In the latter the Court said that Article 101(1) TFEU must be interpreted as meaning that a user of services cannot be a priory responsible for anticompetitive activities of service provider. To be held liable for a concerted practice on account of the acts of an independent service provider supplying it with services one of the following conditions has to be met: – the service provider was in fact acting under the direction or control of the undertaking concerned, or – that undertaking was aware of the anti-competitive objectives pursued by its competitors and the service provider and intended to contribute to them by its own conduct, or – that undertaking could reasonably have foreseen the anti-competitive acts of its competitors and the service provider and was prepared to accept the risk which they entailed.

Legislation adoption is a complex process which brings together assorted actors, each with its own array of attributes, strategies and motives. Legislators rely on the web created for a diverse array of functions, from information diffusion to coalition building. Given its heterogeneous nature, legislative cosponsorship networks have gradually become a focus point in the study of collaborative activity in political settings. The article looks into the history of how social network analysis has been adopted in the study of cosponsorship patterns, at the most used methodologies, explanatory variables and applications within this subfield. It looks at the multiple studies that are dealing with the variables facilitating voluntary cooperation, how they may vary in performance given different national contexts, and how personal interests and institutional constraints (or incentives) intertwine. The last chapter deals with research developed using lessons learned from studying legislative networks. Keywords: social network analysis; cosponsorship networks; legislative networks; centrality measures; explanatory variables; data gathering. ●●●●● Procesul de adoptare a unei legi este unul complex, care reunește o serie de actori, fiecare cu propria sa gamă de atribute, strategii și motive.

Complex organ-sparing treatment for muscle-invasive bladder cancer
Authors: Sakalo A.V. , Gatserelia Z.V. , Sakalo V.S.
Published: May 2022

Background. Bladder cancer ranks 9th in prevalence among malignancies and 2nd among malignant tumors of the human urogenital system. Cysttetomy significantly reduces the quality of life and contributes to the emergence of postoperative complications that can lead to the patient’s death during the first year after the surgery. Along with organ removal in the cases of muscle-invasive bladder cancer (MIBC), organ-sparing operations can be performed on the bladder, which can be an effective alternative to radical cystectomy. Purpose – of the study was to conduct the analysis of the benefits and the oncological results of MIBC treatment using multimodal organ-sparing therapy in comparison with radical cystectomy with ileocystoneoplasty. Materials and Methods. Depending on the treatment method, the patients were divided into 3 groups. The first group included 36 (48,6%) patients who underwent radical cystectomy with ileocystoneoplasty; in the 2nd group there were 22 (29,7%) patients after TUR of bladder tumor with adjuvant chemotherapy; in the 3rd group – 16 (21,6%) patients after TUR of bladder tumor with adjuvant chemoradiation therapy. The patients were selected according to generally recommended criteria for bladder preservation. Overall survival rate, as well as cancer-specific and recurrence-free survival rate was assessed by the Kaplan–Meier method. The median age of the patients in the 1st group was 67 years (in the range from 51 to 76 years old), in the 2nd group – 72 (in the range from 53 to 78 years old), in the 3rd group – 74 (in the range from 62 to 81 years old). Results. The findings show that cancer outcomes are unlikely to differ between the three groups over a five-year follow-up period, but given the significantly better quality of life in MIBC organ-sparing treatment groups, the usage of trimodality therapy for MIBC in selected patients is justified. Up to 19% of patients with MIBC may become potential candidates for organ-sparing treatment (TURB). Adequate local control of the tumor can not be achieved with monotherapy alone (TUR, chemo and/or radiation therapy), but the combination of these methods provides adequate local cancer control. The patients who received complex therapy in presented studies showed fair cancerspecific and overall survival rate. Conclusions. The study proved that bi- and trimodality organ-sparing treatment allows commensurable values of overall, cancer-specific and recurrence-free survival rate to be achieved in comparison with radical cystectomy for selected patients with non-metastatic MIBC. Taking into account the better quality of life, complex organ-sparing therapy – TURD with chemo- and/or radiation therapy, can be considered as an alternative to radical cystectomy in the cases of MIBC.

Background: Non-adherence to antiretroviral therapy (ART) by pregnant women living with HIV/AIDS is a problem that has been reported to have adverse effects on the mother and the unborn child and this is a major public health issue in high- and low-income nations. Virological and clinical success depends critically on elevated adherence to ART, without which maternal disease can develop, with its attendant increase in the risk of vertical mother-to-child transmission. The level of non-adherence to ART is high in many communities in Nigeria. This study assesses the level of ART adherence and identifies factors that influence nonadherence among pregnant women living with HIV/AIDS.

Stress Assessment by the Hemogram Method - Circulating Cells Complicating Reliance on Heterophil/Lymphocyte (H/L) Ratio
Authors: Cotter Paul F
Published: May 2022

The subject is a reexamination of the utility of the heterophil/lymphocyte ratio as a stress measure. The data are obtained from blood films of non-experimental chickens at 3 weeks of age and housed in isolator units. Standard differential counts of 2 x 200 cells indicated total white blood counts (TWBC) were in the range of 30-200(K) with an average of ~100(K); normal to leukemoid reaction levels (N= 23 samples). The H/L average of ~ 0.5 was typical of a non-stress hemogram. However, many atypical cells were identified including small lymphocytes with irregular cell membranes (zeiosis) reactive lymphocytes, resting (small) or activated NK (natural killer lymphocytes) unusual heterophils of three types: classic (HC), typical (HT), variant (HV), and early stages of the granulocyte series. Aggregates of atypical cells (reactive clusters) were also common. Atypia were present in blood samples at all TWBC and H/L levels. These hematological conditions suggest that estimates of stress status solely reliant on H/L data may not convey an accurate blood picture. It is necessary to integrate the calculated H/L with the TWBC and the occurrence of atypical cells to more accurately determine homeostasis.
Depression and Psycho-Social Well Being in emerging adulthood
Authors: Daru Dr Etta Roland , Kaur Dr Kirandeep , Neh Dr Neba Vernat
Published: May 2022

Introduction Depression is defined as a state of feeling sad, severe hopelessness and dejection: a serious medical condition in which a person feels very sad, hopeless, and unimportant and often is unable to live in a normal way. Depression imposes itself not only on adults but it takes its toll on children and adolescents as well. Normally, parents want their children to be happy. Despite their best to provide and protect them, children still encounter disappointments, frustrations, or real heartbreak. The current study is an attempt to investigate depression and possible risk factors in adolescents in relation to psycho-social well-being in adolescents. Methodology A cross sectional survey research design was adopted in order to address the problem of depressive symptoms, risk factors and psychosocial well-being of adolescents in secondary schools. A total of 400 male and female emerging adults served as subjects in the study. Questionnaire was used to collect quantitative data. While qualitative data was collected with the use of focus group discussion and interview to buttress quantitative data collected with questionnaire. Chi- square was used to analyze the quantitative data and a thematic content assessment was used to analyze qualitative data. Results The results revealed that depression is negatively correlated with various dimensions of psycho-social well being and there exist a significant difference among male and female adolescents in context of depression. Again, findings reveal that the psychosocial well-being of adolescents is significantly affected by anxiety symptom. Equally it was retained that loneliness, low self-esteem and aggression has a significant negative effect on adolescents psychosocial well-being. It is thus, recommended that it will necessary to utilize the results of this study to implement programs or courses in psychology that will inform people about the early signs of adolescent risk factors and symptoms of depression. Implication This implies that a good proportion of adolescents in secondary schools are seen to portray some symptoms and risk factors for depression which has negatively affected their well-being both socially and psychologically. It is hope that this study will be helpful in highlighting the undesirable nature of depression among adolescents.

Background: Protamine neutralises heparin after separation from cardiopulmonary bypass. This study aimed to evaluate the effects of lidocaine on protamine induced pulmonary vascular constriction in paediatric cardiothoracic surgery. Methods: This was a single-centre, prospective, double-blind and randomised study conducted among eighty pediatric patients with acyanotic congenital cardiac disease, scheduled for elective on-pump cardiac surgery under general anaesthesia. In the study, the participants were divided into four groups: Group NPHL- nonpulmonary hypertension with lidocaine preconditioning, group NPHS- nonpulmonary hypertension with normal saline (as placebo), group PHL- pulmonary hypertension with lidocaine preconditioning, and group PHS- pulmonary hypertension with normal saline (as placebo). Results: Pulmonary vasoconstriction occurred in 11.25% of cases after protamine administration. Both the NPHS and PHS groups exhibited an increase in mean airway pressure (Paw), Respiratory index (RI), alveolar-arterial oxygen difference (A-aDO2), pulmonary artery pressure (PAP) and decreased dynamic pulmonary compliance (Cydn) and oxygen index (OI) after protamine administration. However, these changes were not observed in the NPHL and PHL groups with lidocaine preconditioning. Plasma levels of TXB2 in the NPHS and PHS groups were higher than the NPHL and PHL groups, but 6-keto-PGF1 alpha levels were lower in the NPHS and PHS groups than in the NPHL and PHL groups. Conclusion: In congenital heart disease, repair without cardiopulmonary bypass is not possible in most cases. Prior to reversing heparin with protamine, preconditioning lidocaine reverses protamine-induced pulmonary vasoconstriction and improves lung function.

This study aims to analyze the physicochemical properties of fat blends between palm kernel olein and stearin in different ratios. Furthermore, it determines the fat blends, which have more than 50 % lauric acid at the sn-2 position. The liquefied RBDPKOo (refined bleached deodorized palm kernel olein) and RBDPKOs (refined bleached deodorized palm kernel stearin) were mixed in proportions of 100:0; 80:20; 60:40; 40:60; 20:80; and 0:100 (w/w), and homogenized at 70 °C for 15 min. Also, the samples analyzed were fatty acid composition, triglyceride profile and physicochemical properties. The results showed the blending of RBDPKOo with RBDPKOs resulted in a change in melting point, iodine value, and behavior. Increased RBDPKOs resulted to a higher melting point, and a lower iodine value of fat blends. A blending with higher RBDPKOs (more than 60 %) resulted in a sharp endothermic peak. Meanwhile, blending of RBDPKOo with RBDPKOs significantly changes the fatty acid composition and triglycerides profiles. The RBDPKOs in the fat blends increased the trilaurin, and the composition as well as the amount of lauric acid at the position of sn-2. In addition, the 2 fat blends obtained with more than 50 % lauric acid at the position of sn-2 were RBDPKOo: RBDPKOs ratios of 40:60 and 20:80, respectively.

RİSK ALMA VE RİSKTEN KAÇINMA DAVRANIŞINA GENETİK YAKLAŞIM
Authors: Güngör Sezen
Published: May 2022

Finans biliminde ve yatırım dünyasında risk, finansal yatırımlarla ilgili bir tehdidin meydana gelme olasılığı ve devamında ise bu olasılığın muhtemel etkilerini içerir. Tanımdan da anlaşılacağı üzere şimdiye kadar literatür riske reaktif olarak yaklaşmıştır. Ayrıca geçmiş literatür incelendiğinde genellikle risk tanımlanırken riskli olay gerçekleştikten sonraki etkiler dikkate alınmıştır. Ancak risk alma davranışı, içinde çok farklı bilim dallarının konusu olan etkiler taşıyan bir kavram olduğu için proaktif bir yaklaşımla ele alınmayı hak etmektedir. Finans piyasalarında yatırımcıların üstlendikleri riskin proaktif olarak ele alınması, yatırımcının risk kabul sınırlarını ve bu sınırların hangi faktörlerce belirlendiğini göstermesi açısından önemlidir. Bu çalışma, yatırımcıların risk alma davranışlarının genetikle birlikte ele alınmasının gerekliliğini ortaya koymaktadır. Literatür incelemesinin yapıldığı bu çalışmada kantitatif genetik yöntemler ve moleküler genetik yöntemlerin kullanıldığı çalışmalar ayrıntılı şekilde incelenmiştir. Bu incelemelerle eğitim cinsiyet, yaş gibi temel demografik faktörlerin dışında kişilik, duygu durum bozuklukları, yakın çevrenin davranışları gibi psikolojik ve sosyolojik pek çok faktörden etkilenebilen risk alma davranışını hem doğrudan hem de psikolojik faktörleri etkileyerek dolaylı olarak etkileyebilen genetik faktörlerin varlığı ortaya konmuştur.
Dos conhecimentos à regulação metacognitiva

Apoiando-se no modelo de monitoramento e controle da cognição que envolve o termo metacognição, este trabalho tem como objetivo apresentar uma abordagem metacognitiva para formação de professores/as de química, apresentando e discutindo como professores/as modificam, ampliam e enriquecem seus conhecimentos metacognitivos sobre os casos investigativos a partir de um processo de regulação metacognitiva. Usando da metodologia de pesquisa-ação, foi proposto um curso de formação voluntária em que participaram seis professores/as. Os dados foram obtidos a partir da gravação de dois encontros, que foi transcrita na íntegra para a análise. Os resultados apontam que os conhecimentos metacognitivos são em sua maioria do tipo declarativo em comparação aos componentes procedimental e condicional, que foram ampliados e modificados no decorrer da regulação metacognitiva. Essa abordagem possibilitou identificar o ciclo cognitivo e afetivo dos/as professores/as, o que contribui para a tomada de consciência sobre os próprios conhecimentos, primeiramente, e avança em direção à regulação metacognitiva.

Este manuscrito teve como objetivo, ao analisar as respostas de um grupo de docentes de Matemática do Paraná participantes de uma oficina do Programa de Formação em Matemática Olímpica, identificar as crenças e concepções a respeito dos saberes e das disciplinas escolares, da escola e da educação escolar; do que é ser professor de Matemática da Educação Básica; do papel desempenhado pela Matemática escolar na formação dos estudantes na sociedade contemporânea. Metodologicamente utilizou-se a Análise Textual Discursiva para analisar as questões abertas e a Estatística Descritiva para as questões em escala de Likert. Teoricamente, fundamentou-se em estudos sobre a noção de disciplina escolar como modelos disciplinar e didático, teorias do currículo e formação de professores. Dentre as conclusões destacam-se que as concepções docentes se aproximam mais de uma tendência teórica crítica para as disciplinas escolares e escola e de uma caixa de ferramentas para a Matemática escolar.

Introdução: As espécies invasoras são aquelas que ocupam novos territórios fora de suas áreas de distribuição natural. As áreas protegidas são prioritárias para a conservação da biodiversidade e a presença de espécies invasoras nestes locais ameaça a sobrevivência de espécies nativas, podendo ocasionar extinções locais e desequilíbrios ecossistêmicos. O Brasil tem sido invadido por diversas espécies de moscas da família Drosophilidae, como Drosophila malerkotliana, Zaprionus indianus e Drosophila nasuta. Esta última é uma espécie nativa da Ásia e um dos drosofilídeos invasores mais recentes do Brasil. Objetivo: Avaliar a preferência ambiental da mosca invasora D. nasuta entre uma área protegida e uma área urbana no domínio da Floresta Atlântica. Material e métodos: Drosofilídeos foram coletados no Jardim Botânico do Recife (área protegida) e no Instituto de Tecnologia de Pernambuco (área antropizada), ambos locais situados na cidade de Recife, Pernambuco, afastados por aproximadamente sete quilômetros. Foram realizadas duas amostragens no período seco (janeiro/fevereiro de 2021) e duas no período chuvoso (maio/junho de 2021) em cada área. Para captura dos drosofilídeos foram utilizadas sete armadilhas por amostragem, as quais foram confeccionadas com garrafas plásticas e iscas de banana e penduradas aleatoriamente a 1,5 metros do solo e distanciadas por 40 metros umas das outras, permanecendo nos locais por três dias consecutivos. Resultados: Foram capturados 36.235 drosofilídeos nas duas áreas investigadas. Drosophila nasuta foi a quarta espécie mais abundante (8.27%), sendo superada apenas pelas invasoras D. malerkotliana (52,81%), Scaptodrosophila latifasciaeiformis (15,54%) e Z. indianus (11,61%). Drosophila nasuta foi mais abundante na área protegida (1.936 indivíduos) em relação a área urbana (1.062 indivíduos). Este padrão difere do apresentado pelas demais espécies invasoras, as quais foram mais abundantes na área urbana. Conclusão: Verificamos maior abundância de D. nasuta no ambiente protegido. As áreas protegidas são prioritárias para a conservação da biodiversidade e a preferência de D. nasuta por estes territórios pode ameaçar a sobrevivência de espécies de drosofilídeos nativos.
