Abstract

ABSTRACT In this study, the attachment and resilience levels of 60‐ to 72‐month‐old Turkish girls and boys were examined in terms of certain demographic characteristics, and the predictive role of attachment on resilience was investigated while controlling for these characteristics. The study was structured as a descriptive study within the scope of quantitative research methods of the survey model. Participants consisted of 361 children and 73 teachers. We collected the data for the study administering the Incomplete Stories with Doll Family Scale to each child for approximately 20 min by the researcher and having teachers complete the Preschool Period Resilience Scale. Independent samples t‐tests, one‐way analysis of variance (ANOVA) and multiple regression analysis were applied. In the study, the least observed attachment style in children was negative, followed by secure, with avoidance the most prevalent. While the child's gender, parental education level and socio‐economic status explained 14% of resilience, it was determined that the attachment variable explained 57.9% of the variance in resilience when common independent variables were controlled. The results of the study highlight the significance of the impact of attachment styles on the resilience of young children. [ABSTRACT FROM AUTHOR]

Abstract

We have investigated real graviton emission in the ADD and RS model of extra dimensions through the photoproduction process pp-> p gamma p-> pGqX at the LHC. We have considered all contributions from the subprocesses gamma q -> G q, where q=u,d,c,s,b,anti-u,anti-d, anti-c, anti-s, anti-b quark. The constraints on model parameters of the ADD and RS model of extra dimensions have been calculated. During numerical calculations we have taken account of 3, 4, 5 and 6 large extra dimensional scenarios. The constraints on RS model parameters have been calculated by considering G -> gamma gamma, e^- e^+, mu^- mu^+ decay channels of the graviton., Comment: 27 pages, 12 figures; final version to appear in PRD

Abstract

We have examined TeV scale effects of extra spatial dimensions through the processes gamma q-> gamma q where q=u,d,c,s,b, anti-u, anti-d, anti-c, anti-s, anti-b. These processes have been treated in a photon-proton collision via the main reaction pp-> p gamma p-> p gamma qX at the LHC. We have employed equivalent photon approximation for incoming photon beams and performed statistical analysis for various forward detector acceptances., Comment: 17 pages, 5 figures

Abstract

We consider solutions of the $2\times 2$ matrix Hamiltonian of physical systems within the context of the asymptotic iteration method. Our technique is based on transformation of the associated Hamiltonian in the form of the first order coupled differential equations. We construct a general matrix Hamiltonian which includes a wide class of physical models. The systematic study presented here reproduces a number of earlier results in a natural way as well as leading to new findings. Possible generalizations of the method are also suggested., Comment: 13 pages, 5 figures.

Abstract

Vaccine hesitancy is considered a major barrier to achieving herd immunity against COVID-19. While multiple alternative and synergistic approaches including heterologous vaccination, booster doses, and antiviral drugs have been developed, equitable vaccine uptake remains the foremost strategy to manage pandemic. Although none of the currently approved vaccines are live-attenuated, several reports of disease flares, waning protection, and acute-onset syndromes have emerged as short-term adverse events after vaccination. Hence, scientific literature falls short when discussing potential long-term effects in vulnerable cohorts. The COVAD-2 survey follows on from the baseline COVAD-1 survey with the aim to collect patient-reported data on the long-term safety and tolerability of COVID-19 vaccines in immune modulation. The e-survey has been extensively pilot-tested and validated with translations into multiple languages. Anticipated results will help improve vaccination efforts and reduce the imminent risks of COVID-19 infection, especially in understudied vulnerable groups.

Abstract

Background Surgery is the primary treatment that can offer potential cure for gastric cancer, but is associated with significant risks. Identifying optimal surgical approaches should be based on comparing outcomes from well designed trials. Currently, trials report different outcomes, making synthesis of evidence difficult. To address this, the aim of this study was to develop a core outcome set (COS)—a standardized group of outcomes important to key international stakeholders—that should be reported by future trials in this field. Methods Stage 1 of the study involved identifying potentially important outcomes from previous trials and a series of patient interviews. Stage 2 involved patients and healthcare professionals prioritizing outcomes using a multilanguage international Delphi survey that informed an international consensus meeting at which the COS was finalized. Results Some 498 outcomes were identified from previously reported trials and patient interviews, and rationalized into 56 items presented in the Delphi survey. A total of 952 patients, surgeons, and nurses enrolled in round 1 of the survey, and 662 (70 per cent) completed round 2. Following the consensus meeting, eight outcomes were included in the COS: disease-free survival, disease-specific survival, surgery-related death, recurrence, completeness of tumour removal, overall quality of life, nutritional effects, and ‘serious’ adverse events. Conclusion A COS for surgical trials in gastric cancer has been developed with international patients and healthcare professionals. This is a minimum set of outcomes that is recommended to be used in all future trials in this field to improve trial design and synthesis of evidence.

Abstract

Laminated composites with ceramic front layers and metallic or composite backing layers have gained attractiveness as 11,lightweight armours, as they exhibit the same ballistic performance with lower area] densities as compared to steels. Drop-weight testing (DWT) has potential for evaluating the low velocity impact behaviour or materials. This testing gives significant ideas and information about failure mechanisms and behaviour of materials under low velocity impact. In this study, DWT of alumina/aluminum laminated composites was done in order to investigate the effects of lamination type, density with respect to area and mechanical property of backing material on the low velocity ballistic performance of these composites. The experimental results showed that the laminated composite with ceramic front layer and aged-aluminum alloy as backing layer was the most effective among different investigated specimens against low velocity impact loads.

Abstract

Laminated composites, containing a ceramic front layer and a metal backing layer, provide better ballistic protection against ballistic threats compared to armor steels. This study presents the influence of the mechanical properties of the backing plate and the areal density on the ballistic performance of the laminated composite. For this aim, three different heat treatments were applied to the steel specimens to get different hardness levels of 40, 50 and 60 HRC. Therefore, three composite specimen groups were prepared according to the mechanical properties of the steel plate. In addition to that each composite specimen group with five different thicknesses was prepared to get five areal densities. After that, the ballistic experiments were carried out against 7.62 mm armor piercing (AP) projectiles in a ballistic laboratory. Composite targets were subjected to a single shot for every specimen and all tests were repeated five times. Experimental results pointed out that, when the hardness of the 4340 steel was increased, the ballistic performance of the composites was decreased. © METAL 2008., 106M211

Abstract

The potential of silicon carbide reinforced Functionally Gradient Material (FGM) to be used as armor material was investigated under the impact of armor piercing projectile. For this purpose, the SiC-Aluminum Alloy (AA) 7075 functionally graded composite at different thicknesses was produced from the metallic and ceramic powders via powder metallurgy method. Before the ballistic testing, the precipitation hardening behavior of the samples was determined. And also, the microstructural characterizations of the samples were done with the aid of microscopy techniques. Next, the FGM samples were tested using armor piercing projectile to analyze their impact behavior. In the produced samples, some pore formation was detected. The ballistic experiments showed that the investigated FGMs (up to a thickness of 25 mm) did not withstand the impact of the projectile. At the tested samples, some major cracks and plug formation were detected at macrolevel while there were some microcracks, deformed and elongated grains in the regions near to the deformation zone of the samples.

Abstract

Laminated composite armors provide significant advantages to the defense systems when considering both the mobility and energy consumption. Among them, alumina faced laminated composite systems have been considered as strong candidates due to their relatively low cost and availability. In this study, the ballistic response of alumina/4340 steel laminated composites was investigated under the impact of 7.62 mm armor piercing (AP) projectiles. The influence of the mechanical properties of the steel backing layer and the areal density on the ballistic performance of these composites was examined. Experimental results showed that the best ballistic protection was found for the composites having the steel backing layer of 40 or 50 HRC (Hardness Rockwell C)., TUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [106M211], This work was supported by the Research Fund of TUBITAK, Project # 106M211.

Abstract

Dual phase steels have the potential to reduce the weight of structural components because of the improved mechanical properties obtained from the two phases: soft ferrite and hard martensite. In this study, the ballistic performance of a low carbon and low alloy steel was investigated in intercritically annealed conditions. To do this, intercritical heat treatments at three different temperatures were applied to the steel samples separately to get three groups of samples having various martensite volume fractions. The full annealing treatment was also performed on a fourth steel group sample for comparison with the dual phase samples. The ballistic testing was carried out using a 7.62 mm armor piercing (AP) projectile. The experimental results pointed out that the ballistic resistance of the dual phase steel increased by increasing martensite content. In addition, deformed shear bands and/or highly distorted microstructures were observed in all samples irrespective of heat treatment after the ballistic testing. Furthermore, there was a remarkable increase in the micro and macro hardness of the investigated steel samples due to the ballistic induced strain. (C) 2009 Elsevier B.V.

Abstract

Ballistic performance of engineering materials should be known in selection of the most suitable armor material to protect civilian or military system with the lowest possible weight against various threats. In this study, the ballistic impact characterization of high-strength steels, namely AISI 4340 and DIN 100Cr6, was investigated using 7.62-mm armor piercing (AP) projectiles by considering four hardness levels and five areal densities. The main aim was to examine the effect of hardness and areal density on the ballistic behavior of these steels. Hence, four different heat-treatment schedules were applied to these steels to get different mechanical properties. After ballistic testing, macro and micro examinations of the specimens were carried out to clarify their failure mechanisms. According to the results, the AISI 4340 steel having a hardness of 50 HRC showed the best ballistic performance among the investigated materials., Research Fund of TUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [106M211], This work was supported by the Research Fund of TUBITAK, Project # 106M211.

Abstract

Laminated composites have great potential in producing lightweight armors. This study presents the experimental study of the low velocity ballistic behavior of Al(2)O(3)/Al2O24 (alumina/aluminum) laminated composites against 7.62 x 51 mm armor piercing (AP) projectiles. The effects of mechanical properties of backing material and laminating type as well as the adhesive type on the ballistic performance of the composite armor were investigated. Furthermore, an inspection of the fracture surfaces was carried out to analyze deformation mode by using a scanning electron microscope (SEM). The test results showed that utilization of alumina as a front layer and Al2O24-T6 as a backing layer in the composites with an alumina/aluminum thickness ratio in the range of 1-3 maintained the highest ballistic performance. Moreover, composites bonded with polyurethane exhibited more resistance to spalling of ceramic tiles than those bonded with epoxy, even though adhesive type had no appreciable effect on the ballistic performance of the composites.

Abstract

In this study, the functionally graded materials (FGMs) bearing three layers were produced via hot pressing to investigate their ballistic performances against 7.62 mm armor piercing (AP) projectile. In the FGM samples, the bottom layer was considered as unreinforced AA7075 alloy, whereas the middle and top layers were made of the AA7075 composite layers having various proportions of B4C particles. Prior to the ballistic testing, the hardness change in the layers with respect to aging time at different temperatures was determined. And then, the ballistic testing of the samples was performed at a ballistic laboratory using 7.62 mm AP projectile. In the ballistic testing, five separate specimens for each FGM group having fixed composition and thickness were used. The experimental results showed that the ballistic impact resistance of the investigated FGMs increased with increasing boron carbide content and the thickness in the layers. Moreover, there were no separations observed between the layers in the failed samples., This work was supported by the Research Fund of TUBITAK, Project # 110M034.

Abstract

Steels have been widely used as armour materials in defence applications, but they have the disadvantage of a relatively high density. Hence, they are not suitable for lightweight armour production. On the other hand, laminated composites have important potential on the reducing armour weight compared to steels for the same ballistic protection. This study presents the ballistic performance of steel against 7.62 mm armour piercing projectiles. High strength low alloy steel (50CrV4) was chosen as steel armour for ballistic testing. Three areal density values were kept constant to compare ballistic performance of steel armour specimens with alumina/aluminum laminated composite specimens. In addition, in steel samples, the effect of hardness on the ballistic performance was examined. Furthermore, failure mechanisms were investigated after ballistic testing. According to the experimental results, laminated composites maintained 26% weight saving compared to steel. (c) 2006 Elsevier Ltd. All rights reserved.
