Inclusión y diversidad, heterosexualidad y desobediencias sexogenéricas: aportes teórico-político-epistemológicos para repensar el discurso pedagógico de la Educación Sexual Integral (ESI)
Authors: Rojas Alejandro
Published: December 2019

En el discurso pedagógico de la EducaciónSexual Integral (ESI), inclusión y diversidad sexualconfiguran un binomio conceptual relevante. Dado eluso acrítico de esta dupla, el propósito del presentetrabajo es transparentar algunas de sus implicanciaspolítico-epistemológicas a través de las cuales se perpetúanprivilegios y subalternidades. En relación a ello,se ha de plantear un análisis reflexivo basado en elconcepto de heterosexualidad como régimen político deopresión, con la finalidad de proponer el reemplazo deuna pedagogía de la inclusión de la diversidad sexualpor una pedagogía celebratoria de las desobedienciassexo-genéricas.
"Explicar bien, aprender bien". La relación con el saber en las voces de los alumnos
Authors: Cademartori Patricia , Grimaldi Verónica
Published: December 2019

En este artículo compartimos algunos de los análisis que venimos produciendo al interior de nuestro equipo de investigación sobre la relación con el saber matemático escolar de adolescentes que concurren a una escuela pública ubicada en una zona de quintas en la periferia de la ciudad de La Plata, provincia de Buenos Aires.A través de entrevistas en profundidad que realizamos a algunos alumnos, encontramos una riqueza particular ligada a las consideraciones que hacen acerca de su propia trayectoria matemática escolar.El planteo de una mirada historizada, que se fue configurando a lo largo de las entrevistas, nos ha permitido identificar, caracterizar y diferenciar distintos momentos de sus vidas vinculados a diferentes formas de relacionarse con el saber matemático, mediadas por distintos profesores. A diferencia de otros trabajos en los que se analiza la mirada de los alumnos sobre un momento particular, la posibilidad de historizar su relación con el saber ha propiciado la emergencia de nuevos aspectos a ser analizados. Incorporar la perspectiva de los alumnos en nuestro estudio nos permite aproximarnos a la comprensión de ciertas posiciones que parecen adoptar en el aula de Matemática.
La importancia de las relaciones en la práctica profesional docente. Un estudio de casos
Authors: Soto Gabriel Rubén , Villagra Nelson Tomás , Correa Franco Ignacio
Published: December 2019

El conocimiento matemático profesional que los profesores de matemática utilizan en su tarea se basa en las relaciones entre la matemática de la formación y la matemática a enseñar en el aula. Tales relaciones, surgidas en diferentes momentos de la formación, son utilizadas a menudo por los docentes para establecer jerarquías entre los conceptos matemáticos que se enseñan en la escuela. Es importante entonces identificarlas para poder diseñar e implementar dispositivos de formación que permitan a los profesores de matemática, en formación o en ejercicio, profundizar y fortalecer sus saberes profesionales. Presentamos un método de identificación y cuantificación de tales jerarquías, basado en las nociones de centralidad en redes sociales, para explicitar las relaciones entre los conceptos matemáticos que los docentes tienen a disposición para enseñar y compararlas con la matemática de su formación.
DRDO and Expectations of Stakeholders
Authors: Bhushan Gopal , Madhusudan M.
Published: December 2019

DRDO is India’s major credible research and development organization that enables self-reliance and indigenisation of defence technologies and weapon systems to empower India in the emerging geo-political balance. The Organisation has its genesis in a technical inspection agency which over the years have transformed into a highly professional R&D organization with strong design and technology capabilities and skilled entrepreneurship to undertake development of state-of-the-art defence systems. DRDO driven R&D efforts have catalysed the growth of domestic defence and civilian industries in the country as well. The overarching endeavours of DRDO encompassing academia, private industry and Defence PSUs have helped in establishing a self-reliant defence industrial eco-system and collectively all have contributed in the Hon’ble Prime Minister’s vision of “skill development” and “Make-in-India”. Yet, DRDO’s struggle at the national level continues since Armed Forces continue to depend on imports for major acquisitions. Indigenous options have not always established themselves as the preferred options even when they are available. The acceptability of DRDO developed products remains at a low ebb. The question is what more DRDO should do to ensure the acceptability of the users? This study examines the evolution of the DRDO and whether over the years DRDO has done enough or should do more to increase its visibility, acceptability, credibility and respectability? And how DRDO should reposition itself beyond MoD/Armed Forces in the national and international context to fulfill the ambitions of the country to play global roles? This paper also discusses how building the brand “DRDO” may possibly help DRDO.

Authors: Elshenawy Tamer Abd , Seoud Mohamed Aboel , Abdo G. M.
Published: December 2019

In addition to its usage as a top attack ammunition in the battle field against troops, 120 mm mortar bomblethas been recently used in the terror attacks against military shelters and civil constructions. This research studiesthe protection of vehicle and personnel military shelters against mortar fragmentation warhead projectile and it’sdestroying effects. The mortar warhead threat combines both blast load and ballistic fragment penetration effects. Composite structure layers are proposed herein to be integrated with concertina walls to achieve full protection against the mortar projectile destroying effects. The current paper investigates the ability of the proposed layers to stop the mortar’s fragments and to mitigate its blast load. The velocity and the mass distribution of the produced projectile fragments were estimated using Split-X software. Besides, the ability of the proposed protection layers to stop the fragments and mitigate the blast wave was evaluated using AUTODYN hydrocode. A static firing test was then performed to validate the theoretical results and verify the effectiveness of the proposed protection added layers. The current study showed that the proposed composite layers are sufficient to protect the military shelters from the mortar’s destroying ballistic effects.

Published: December 2019

Due to some extraordinary thermo-mechanical properties, silicon carbide is considered one of the best materials used for high temperature applications in defence and aerospace. Polycarbosilane (PCS) has been widely used as SiC precursor. This paper describes the research and development work undertaken to establish the technologies for synthesis and characterisation of PCS, fabrication process and characterisation of Carbon fibre reinforced SiC matrix (C/SiC) composite laminates and shaped articles. The molecular weight and softening point of the PCS was found to be 1400-1800 Mn and 140-150 °C respectively. Flexural stress of the unidirectional (UD) C/SiC composites and bidirectional (2D) C/SiC composites was found to be 400-450 MPa and 300-350 MPa respectively. Tensile stress of the 2D C/SiC composite was found to be around 200 MPa. Coefficient of thermal expansion and thermal diffusivity of the 2D C/SiC composites at RT- 1000 °C were found to be in range of 0.3-2.2×10-6/ °C and 32-6 mm2/s respectively. The fabrication process developed for the UD and 2D C/SiC composites using the indigenous PCS has been also demonstrated to fabricate typical size divergent rocket nozzle and hot structure. Fabrication process of the SiC fibre has also been described in brief.
Genetic Algorithm Optimisation of a TNT Solidification Model
Authors: Susantez Çiğdem , Caldeira Aldélio Bueno
Published: December 2019

The control of the solidification process of energetic materials is important to prevent manufacturing defects in high explosive ammunitions. The present work aims to propose an optimisation procedure to determine the value of the model parameter, avoiding the traditional trial and error approach. In this work, the solidification of TNT has been numerically modelled employing apparent heat capacity method and the model parameter was optimised using genetic algorithm. One dimensional numerical model has been solved in Comsol Multiphysics Modeling Software and the genetic algorithm code was written in Matlab. The Neumann’s analytical solution of the solidification front was used as a reference to build the fitness function, following the inverse problems concepts. The optimum model parameter has been predicted after 20 generations and among 30 candidate solutions for each generation. The numerical solution performed with the optimised model parameter has agreed with the analytical solution, indicating the feasibility of the proposed procedure. The discrepancy was 3.8 per cent when maximum difference between analytical and numerical solutions was observed.

Published: December 2019

Koya city, like any other city in the world, faces a critical environmental problem which is global warming and the increase in the rate of production of gaseous pollutants. This research is involved with the negative effects of private Electrical Power Generators (EPGs) on the environment in Koya City. The environmental pollutants resulted from EPGs were investigated by performing an actual study on land for the number of (EPGs), types, and distribution. Koya city is divided into 18 quarters. The investigation covers a period from 2009 to 2017, included. The production of power was increased due to the increase in the number of generators and supplying hours. The power production in 2009 was 23,850 megawatt (MW) whereas it was 49,635 MW in 2017. The amount of fuel consumed in 2009–2017 was relatively increased from 30,000 to 62,500 barrel/year. The total amount of pollutants was increased by about 108% during the period 2009–2017. The results showed that the most significant increase in pollutants was carbon dioxide (CO2). The annual amount of (CO2) emitted in 2009 was 6588 tons whereas it has increased in 2017–13710 tons. The conclusion of this study was that the highest pollution occurred in the center of Koya City in Nabeel quarter, which represented 22% of the whole pollutants.
Docking Study to Predict the Efficacy of Phosphatidylinositol 3-Kinase α Inhibitors
Authors: Chawsheen Mahmoud A. , Al-Bustany Hazem A.
Published: December 2019

The phosphatidylinositol 3-kinase (PI3K) family comprises lipid kinases that cross-link signals between living cells and their surroundings. PI3Ks are classified into several groups and isoforms with specific characteristics and functions. Genes encoding PI3Ks are mutated in several types of cancer, and their isoforms have varying capacity in promoting cell signaling and cancer progression. Many compounds have been introduced as PI3Kα inhibitors, but not all of them have the same inhibitory effects. For successful PI3K-related biomedical experiments, it is vital to select the most specific and potent compounds with the highest inhibitory effects for targeting this kinase. In this study, we investigate 28 well-recognized PI3Kα inhibitors through predicting their specificity and potency using the docking software AutoDock Vina. Our data showed that PF 05212384 had the highest docking score (−9.2 kcal/mol), and 3-methyladenine had the lowest docking score (−4.8 kcal/mol). Our data also showed different types of interactions and bonds formed between the inhibitors and protein residues. In conclusion, PF 05212384 and AZD 6482 compounds are the best candidates for targeting PI3Kα. In addition to hydrophobic interactions in the PI3Kα binding pocket, the formation of hydrogen bonds between these inhibitors and binding pocket residues was confirmed.
Theoretical Study of the [4+2] Cycloaddition Reaction of Trifluoroethylene with Five-membered Chalcogens Heterocyclic Compounds
Authors: Mohammad-Salim Haydar A. , Abdallah Hassan H.
Published: December 2019

[4+2] cycloaddition reaction has enormous significant in organic chemistry synthesis reactions and yet remains unexplored for the synthesis of fluorine-containing compounds. A density functional theory study of the stereo- and regioselectivity of the [4+2] cycloaddition reaction of trifluoroethylene with furan, thiophene, and selenophene was carried out in the gas phase. The B3LYP functional is used throughout in combination with 6-31G(d) basis set. The analysis of stationary points and the energetic parameters indicates that the reaction mechanism is concerted and confirms that the exo-adducts are thermodynamically and kinetically more favored than endo-adducts. The calculated branching ratio indicates that the exo-adducts have the higher percent yield than endoadducts and the yield of endo-adducts is increased only slightly on proceeding from furan, through thiophene, and onto selenophene. The analysis of the frontier molecular highest occupied molecular orbital (MO) and lowest unoccupied MO orbitals indicates that the exo-adducts are more stable due to their higher energy gab. The reaction energies were compared to the MP2/6-31G(d) and CCSD(T)/6-31G(d) calculations.
Skin Temperature Distribution over Human Head Due to Handheld Mobile Phone Call using Thermal Imaging Camera
Authors: Khaleel Yazen A. , Yahya Salah I. , Ibrahim Rahel Kh.
Published: December 2019

The possible biological hazards due to the mobile phone electromagnetic (EM) field exposure are caused mainly by a temperature rise in tissue. Hence, the calculation of temperature in tissue may be more realistic than the calculation of specific absorption rate (SAR) due to the more direct relationship between temperature and safety. The heat transfer to human tissue due to a phone call is caused by a combined effect of conductive heat transfer caused by the basic non-microwave-related activity of the mobile phone and the absorption of the microwave. This paper investigates the role of heat transfer in living tissue due to thermal conduction. This is achieved using a thermal imaging camera to measure and map the skin temperature distribution over human head due to mobile phone EM emission. Two commercial mobile phone brands, that is, Apple iPhone 7 Plus and Huawei P20 Pro, are used at 1800 MHz cellular connection and approximate radiated power of 0.125 W to measure the skin temperature over human head at both, cheek and tilt position for 6 and 30 min calls. The results show that in spite of the direct proportion between the deposited SAR and temperature increase in human tissues, the heat transfer due to thermal conduction may not directly proportional to the SAR, where other factors may play important roles, for example, mobile phone chassis material, heated battery, antenna location inside the mobile phone, and mobile phone position in close proximity to head.
Education Needs to Support Architecture, Engineering, and Construction Collaboration Using Building Information Modeling
Authors: Rostam Dilan M.
Published: December 2019

Projects in the construction industry involve multidisciplinary collaboration between the disciplines of architecture, engineering, and construction (AEC), and others. Conventionally, the collaboration between these disciplines relied on the recurrent exchange of relevant drawings and documents. Building information modeling (BIM) as a model-based process has given AEC professionals the tools to more efficiently plan, design, construct, and manage buildings and infrastructure. Yet the AEC industry has been reluctant in fully adopting the BIM as a single standard. This study explores and identifies the bottlenecks in adopting BIM as a single product lifecycle standard in the construction industry and advise on educating new engineers to become the generation to use a virtual collaborative working space covering the entire building lifecycle. Two conducted surveys targeting the AEC academia and industry revealed the needs for multilevel cross-disciplinary interactive collaborative BIM process modeling, and skilled workforce to increase the graduates’ marketability and BIM adaptability. It is concluded that the new age collaborative culture requires new generation of AEC players that are enabled to work on a shared virtual product model supported by proactive BIM skills learned through undergraduate programs.

The interest in silicon vapor chambers (SVCs) has increased in the recent years as they have been identified as efficient cooling systems for microelectronics. They present the advantage of higher thermal conductivity and smaller form factor compared to conventional heat spreaders. This work aims to investigate the potential miniaturization of these devices, preliminary to integration on the backside of mobile device chips, located as close as possible to hotspots. While detailed numerical models of vapor chamber operation are developed, an easy modeling with low computational cost is needed for an effective parametric study.  Based on the study of the operating limits, this paper shows the thinning potential of a water filled micropillar for a device operating below 10 W and identify the corresponding vapour core height, and wick thickness.

Authors: Kaur Dr. Kamalpreet
Published: December 2019

The purpose of this study was to determine the pH and electrical conductivity in soil of different villages of   barnala district (Punjab,India ) and their harmful effects on human health. Samples of soil were collected from agricultural fields of four different villages of barnala region such as Rure ke kalan, Gunas, Handiaya and cheema from five different layers(0-10 cm; 10-20 cm; 20-30 cm; 30-40 cm and 40-50 cm depth).There are three industrial sites in barnala district and these four villages are located near to these industial sites. In this study, adverse effect of different industries on fields of these four villages were investigated. Handiaya village has high values of pH and electrical conductivity while Gunas and Cheema villages have lowest value of electrical conductivity and pH respectively. when textile effluent reaches the soil or underground water it causes bad effect on human health such as people may suffer from alkalosis which is due to high pH and can lead to arrhythmia which means irregular heartbeat.

Background and aims: Entamoeba histolytica is an intestinal parasite and a causative agent of amoebiasis which is a common life-threatening parasitic disease. This study was intended to determine the prevalence of E. histolytica and to provide the primary data about its infections among the patients attending Nyanza District Hospital in Rwanda. Methods: Bottles were used to collect 138 stool specimens from patients. All the samples were physically analyzed based on their colors, states, and the presence of blood or mucus. The wet preparation method and zinc sulphate floatation technique were used to concentrate the parasites. Microscopic analysis was done to examine the presence of cysts and trophozoites. Data were statistically analyzed by SPSS using chi-square test and independent t test. Results: The prevalence of E. histolytica was 15.94%. The sex distribution of infections revealed that males (21.54%) were more infected than females (10.95%). The highest prevalence of E. histolytica was found in the age group of 1-19 years old (27.11%) and the lowest prevalence was observed in the age group of 20-39 years old (6.89%). A prevalence of 33.33% was reported among the people who directly drink tap water and 40% of infections among the patients who did not wash their hands before eating and after using latrines. Conclusion: Overall, E. histolytica is still considered as a health burden in Nyanza District Hospital. Therefore, it is vital to control direct exposure to its risk factors for mitigating the occurrence of amoebiasis.

Background and aims: Having a child with attention deficit hyperactivity disorder (ADHD) may have an impact on the quality of life of his/her parents, particularly his/her mother. However, very limited studies have addressed this issue in Iran and the world. Therefore, the aim of this study was to examine the quality of life in the mothers of children with ADHD and its effective factors. Methods: The present descriptive-analytic study was carried out in Tehran from April to September 2016. A total of 110 mothers of ADHD children were enrolled in the study through a convenience sampling method, who referred to psychiatric centers of Tehran University of Medical Sciences. An informed consent form was obtained from all the participants as well. In addition, a researcher-made checklist for demographic characteristics and the 36-item Short Form of Health Survey Questionnaire (SF-36) were utilized for data collection. The collected data were then entered into SPSS 16 statistical software. Finally, descriptive tests (mean and median) and statistical tests including Pearson correlation test, independent t test, and one-way analysis of variance (ANOVA) were used for data analysis. Results: The mean age of participated mothers was 39.5 years and most children were males (76.4%). The mean overall score of the quality of life was 60.6±20.4. Among the eight dimensions of the questionnaire, participants achieved the lowest score regarding the dimension of "the role limitations due to emotional problems" with the mean score of 52.43, while the highest score was observed in terms of "the physical function" dimension with the mean score of 77.30. No significant relationship was observed between any of the demographic characteristics and the mean overall score of the quality of life (P>0.05). Conclusion: In the present study, the quality of life of the mothers was not significantly different from the quality of life of normal mothers. However, the healthcare team should pay more attention regarding some dimensions of the quality of life. Eventually, similar studies are recommended to be conducted due to the lack of sufficient evidence regarding this issue among the mothers of ADHD children.

Background and aims: Toxocariasis caused by the larvae of Toxocara spp. is a zoonotic infection with global distribution that is considered an important health problem in the humans. The soil is regarded as the main source of the transmission of Toxocara infection to susceptible hosts. This study investigated the existence of Toxocara spp. ova in rural and urban public areas of Chaharmahal and Bakhtiari province. Methods: A total of 180 soil samples were randomly collected from 74 public places from urban and rural areas of nine counties of Chaharmahal and Bakhtiari province during May to September, 2017. The samples were examined for Toxocara spp. eggs by the modified sucrose flotation method. Results: The contamination rate of the soil samples with Toxocara spp. ova varied within 0%-18.1% in different counties. Overall, 9 (5%) out of 180 examined soil samples were found positive for Toxocara spp. ova. Of nine investigated districts, Toxocara spp. ova were observed in four counties and the highest rate of soil contamination was found in Farsan county with 18.1%. Finally, the prevalence of Toxocara spp. eggs was more in the rural areas (6.7%) compared to the urban ones (3.3%). Conclusion: This study was the first investigation regarding the contamination of Toxocara spp. eggs in the soil of public places in rural and urban areas of Chaharmahal and Bakhtiari province. According to the results, the rate of soil contamination in this region was lower compared with the other parts of Iran. Therefore, a further study is required to determine factors that may be involved in the distribution of Toxocara spp. in different areas of this province.

López-Segovia, M, Vivo Fernández, I, Herrero Carrasco, R, and Pareja Blanco, F. Preseason injury characteristics in Spanish professional futsal players: the National Futsal League (LFNS) project. J Strength Cond Res 36(1): 232–237, 2022—This study aimed to examine the incidence of injuries and their characteristics among professional Spanish futsal players during the preseason period and to compare injury-related variables in the context of both competition and training. Eleven futsal teams belonging to the First and Second Spanish Division and 161 players participated in the study. Characteristics of injuries, including type, location, cause and time of injury, injury recurrence, and duration of absence, were recorded. A total of 62 injuries were reported; injury rates of 9.9 (95% confidence interval [CI]: 7.0–12.5) injuries/1,000 training hours and 61.1 (95% CI: 25.7–96.5) injuries/1,000 match hours were collected. These data indicate a mean of 5.64 ± 2.66 injuries per team during the preseason period. Of these injuries, 92.1% involved the lower limbs. When data from training and competition were analyzed together, the highest incidence of injuries affected the ankle (21%), followed by the hip/groin and knee (19.4% each). The most common type of injury was muscle rupture/tear/strain (29.0%). During training, the highest percentage of injuries were located in the knee (23.9%), followed by the ankle and hip/groin (21.7% in each case), while during matches, the thigh (35.7%) followed by the ankle (21.4%) was the regions most affected. A significant relationship (p = 0.008) was observed between injury cause (without contact, with other player, with the ball, and others) and injury context (training, match). To conclude, the results of this study suggest the need for injury prevention protocols focuses on the ankle and the knee joints and muscle strain prevention.

Forsyth, JJ and Burt, D. Sex differences in recovery from sprint interval exercise. J Strength Cond Res 36(2): e41–e48, 2022—The purpose of the study was to examine whether there were differences between men and women in energy metabolism after a bout of sprint interval training (SIT). Sixteen men (mean ± SD [95% confidence interval] for age, stature, body mass, and fat-free mass [FFM] of 25.4 ± 5.9 [22.3–28.6] years, 181.3 ± 7.0 [177.6–185.0] cm, 82.7 ± 13.3 [75.6–89.8] kg, and 69.0 ± 10.6 [63.4–74.6] kg FFM, respectively) and 16 eumenorrheic women (26.1 ± 5.5 [23.1–29.8] years, 164.1 ± 8.7 [159.5–168.7] cm, 72.0 ± 15.4 [63.8–80.2] kg, and 51.6 ± 8.5 [47.0–56.1] kg FFM), tested in the mid-luteal phase of their menstrual cycle, completed a SIT protocol, consisting of 4 × 30-seconds Wingate sprints at 0.065% FFM. Respiratory variables were used to estimate energy metabolism after (post-SIT) and 24 hours after the bout of SIT (24 hours post-SIT). Compared with women, men had significantly higher post-SIT mean fat oxidation rates (0.10 g·min−1 and 0.17 g·min−1, respectively, F
(1,30) = 34.82, p < 0.001,

= 0.54), energy expenditure (1.28 ± 0.26 and 1.82 ± 0.40 kcal·min−1, respectively, F
(1,30) = 20.759, p < 0.001,

= 0.41), excess post-exercise oxygen consumption values (1.91 ± 0.60 and 3.02 ± 1.58 L, F
(1,30) = 6.882, p < 0.014,

= 0.19), and lower relative carbohydrate oxidation rates (0.0007 ± 0.0013 and 0.0018 ± 0.0007 g·min−1 per kg FFM, respectively, F
(1,30) = 10.506, p < 0.003,

= 0.26). The higher metabolic values post-SIT for the men compared with the women might be explained by the men having a greater FFM and having exercised at a higher exercise intensity. Practically, these findings could mean that, if prescribing SIT as a strength and conditioning professional, men and women could respond differently in terms of energy expenditure after exercise.

Saeterbakken, AH, Stien, N, Pedersen, H, and Andersen, V. Core muscle activation in three lower extremity exercises with different stability requirements. J Strength Cond Res 36(2): 304–309, 2022—The aim of the study was to compare core muscle surface electromyography (sEMG) during 3-repetition maximum (3RM) and the sEMG amplitude in the turnover from the descending to ascending phase in leg press, free-weight squats, and squats using the Smith machine. Nineteen women with 4.5 (±2.0) years of resistance training were recruited. After one familiarization session, the subjects performed 3RM in randomized order measuring electromyographic activity in the rectus abdominis, external oblique, and erector spinae. The exercises with the lowest stability requirements (leg press) demonstrated 17–59% and 17–42% lower core muscle sEMG amplitude than free weights and the Smith machine, respectively. No statistically significant differences were observed between the Smith machine and free weights. No statistically significant differences in turnover sEMG amplitude in the rectus abdominis between the exercises was observed, but lower sEMG amplitude was observed in external oblique and erector spinae in leg press compared with the other exercises. The 3RM loads in leg press were 54 and 47% greater than squats using the Smith machine and free weights, with 5% greater loads with the Smith machine than with free weights. In conclusion, lower mean and turnover core muscle sEMG amplitude were observed with the leg press but greater 3RM loads compared with squats with the Smith machine and free weights. The authors recommend that resistance-trained individuals use squats to include the core muscles in the kinetic chain, but there is no evidence that greater stability requirements (free weights instead of the Smith machine) will result in greater core muscle sEMG amplitude.

Published: December 2019

Research has demonstrated mentalizing impairment associated with borderline personality disorder (BPD) in adolescents. However, mentalizing performance in adolescents with BPD has never been compared to that of psychiatric control and healthy control adolescents simultaneously. The present study aimed to (a) compare implicit and explicit mentalizing, and hypermentalizing errors in implicit mentalizing, across youth with BPD and psychiatric and healthy controls, and (b) evaluate the association of borderline features with mentalizing deficits over and above internalizing and externalizing. Psychiatric inpatients with BPD (n = 139), inpatient psychiatric controls (n = 310), and healthy adolescents (n = 134) completed two mentalizing tasks, an interview assessing BPD, and measures of psychopathology. Results showed that BPD specificity could be demonstrated only for implicit mentalizing and hypermentalizing. Explicit mentalizing deficits did not differ between BPD and psychiatric control groups. Borderline features had unique associations to implicit mentalizing and hypermentalizing, over and above internalizing and externalizing.

While intrinsic changes in aging hematopoietic stem cells (HSCs) are well characterized, it remains unclear how extrinsic factors affect HSC aging. Here, we demonstrate that cells in the niche—endothelial cells (ECs) and CXCL12‐abundant reticular cells (CARs)—highly express the heme‐degrading enzyme, heme oxygenase 1 (HO‐1), but then decrease its expression with age. HO‐1‐deficient animals (HO‐1−/−) have altered numbers of ECs and CARs that produce less hematopoietic factors. HSCs co‐cultured in vitro with HO‐1−/− mesenchymal stromal cells expand, but have altered kinetic of growth and differentiation of derived colonies. HSCs from young HO‐1−/− animals have reduced quiescence and regenerative potential. Young HO‐1−/− HSCs exhibit features of premature exhaustion on the transcriptional and functional level. HO‐1+/+ HSCs transplanted into HO‐1−/− recipients exhaust their regenerative potential early and do not reconstitute secondary recipients. In turn, transplantation of HO‐1−/− HSCs to the HO‐1+/+ recipients recovers the regenerative potential of HO‐1−/− HSCs and reverses their transcriptional alterations. Thus, HSC‐extrinsic activity of HO‐1 prevents HSCs from premature exhaustion and may restore the function of aged HSCs.
A distinct matrix representation of the planar kinematic chains and isomorphism recognition
Authors: Alam M. S. , Suhaib M.
Published: December 2019

Structural synthesis of kinematic chains has been an indispensable area of the mechanism-design problem. The duplication may occur while developing kinematic chains. Therefore, an isomorphic test is required to eliminate duplication. For this purpose, the numbers of methods are proposed during recent years. However, most of the methods are complex and difficult to understand, and fulfil the only primary condition, but not the secondary conditions for isomorphism detection. In the present work, a new method is introduced to detect isomorphism in planar kinematic chains (KCs) fulfilling both primary and secondary conditions. First, KC’s are topologically transformed into skeleton diagrams, and then skeleton matrices [S] and identification strings [IS] are formulated consequently. In order to detect isomorphism, the IS is considered as an invariant string of a KC which in turn, enables the detection of isomorphism between the KCs. The proposed method accurately recognizes isomorphism up to 12 links KCs with no counter examples found in the literature. Three examples with one degree of freedom having 10 links 12 joints, 10 links 13 joints and 12 links three degree of freedom systems are introduced to reveal the reliability and strength of the proposed method.

Published: December 2019

Fiber metal laminates (FMLs) offer significant improvement over current available materials for structure materials due the excellent mechanical properties. In this work, the dynamical mechanical properties of the carbon fiber/epoxy, glass fiber/epoxy, aluminium 2024-T0, and fiber metal laminates was carried out. The composite materials have been manufactured by hot press machine. Non-destructive testing techniques are being used in the characterization of composite materials. In this work, free vibration analyses by striking an impact hammer at the free end were conducted to determine the dynamic characteristics of the samples. The results show that combination glass fiber/epoxy with aluminium 2024-T0 offer greater natural frequency value compare to carbon fiber/epoxy with aluminium 2024-T0. The laminate thickness of play a dominant role in differences of natural frequency values.
