Operators applied to polynomial structures on the semi-tangent bundle
No full text<p>Investigating the Tachibana and Vishnevskii operators used on X-vv and (c) X in accordance with the almost paracontact structure in the semi-tangent bundle t(M) is the primary goal of this work. Additionally, in the almost paracontact structure, these relationships will be examined for some special vector fields. Studying the Lie derivatives of the almost paracontact structure and almost contact structure on the semi-tangent bundle t(M) with regard to X-vv and X-HH is the secondary goal of this paper.</p>
The Effect of a Psychoeducation-Based Intervention Administered to Pregnant Women with Traumatic Childbirth Perceptions on Maternal Bonding, Breastfeeding, and Postpartum Depression Levels
No full text<p>This study aimed to evaluate the effects of a psychoeducation-based intervention delivered during the prenatal period to pregnant women with a traumatic perception of childbirth on their traumatic childbirth perception, maternal bonding, breastfeeding, and postpartum depression. This randomized controlled experimental study was conducted between April 2023 and May 2024 at the antenatal outpatient clinic of the Obstetrics and Gynecology Department of a metropolitan training and research hospital. The research sample consisted of 80 pregnant women (40 intervention group and 40 control group). Data were collected using an Introductory Information Form, the Traumatic Childbirth Perception Scale (TCPS), Mother-to-Infant Bonding Scale (MIBS), Breastfeeding Self-Efficacy Scale–Short Form (BSES-SF) and Edinburgh Postnatal Depression Scale (EPDS). Participants in the intervention group attended five 50-minute group psychoeducation sessions held at one-week intervals. Following the psychoeducation program, the intervention group demonstrated a statistically significant decrease in their TCPS scores at both the second and final evaluations (p< 0.01). The total MIBS scores of the intervention group were significantly lower than those of the control group (p< 0.01), indicating stronger bonding. The total BSES-SF scores of the intervention group were significantly higher than those of the control group (p< 0.01). Moreover, the total EPDS scores were significantly lower in the intervention group than in the control group (p< 0.05). The psychoeducation-based intervention administered to pregnant women with traumatic childbirth perceptions was found to reduce the perception of traumatic childbirth, strengthen maternal–infant bonding, increase breastfeeding self-efficacy, and lower the risk of postpartum depression.</p>
Instrument-Assisted Soft Tissue Mobilization and Percussion Massage Therapy in Cervical Disc Herniation: A Randomized Controlled Study
No full text<p>Cervical disc herniation (CDH) is a prevalent musculoskeletal condition marked by chronic neck pain, impaired proprioception, kinesiophobia, and functional limitations, often requiring multimodal conservative management. Myofascial interventions, particularly Instrument-Assisted Soft Tissue Mobilization (IASTM) and Vibration Therapy (VT), have emerged as supportive approaches within conservative physiotherapy programs. This randomized controlled trial aimed to evaluate the comparative effectiveness of two emerging myofascial interventions (IASTM and VT) on pain, disability, fear of movement, and proprioceptive function in individuals with CDH. In this double-blinded randomized controlled trial, 57 individuals diagnosed with CDH were randomly assigned to three groups (n = 19): Conventional Therapy (CT), CT combined with VT, and CT combined with IASTM. Interventions were administered over a 3-week period. Primary outcomes included pain (Visual Analog Scale) and neck disability (Neck Disability Index); secondary outcomes were kinesiophobia (Tampa Scale for Kinesiophobia) and JPS (Laser Pointer Assisted Test). All groups demonstrated significant within-group improvements across all outcome measures (p < 0.001). Compared to the CT group, the VT and IASTM groups exhibited significantly greater improvements in pain, kinesiophobia, and JPS parameters (p < 0.001). No statistically significant differences were found between the VT and IASTM groups. IASTM and VT provide additional clinical benefits over conventional therapy alone in the management of CDH, particularly in reducing pain and kinesiophobia and enhancing proprioceptive function. Both interventions may be effectively integrated into conservative rehabilitation protocols targeting sensorimotor dysfunction in CDH.</p>
Football, diaspora, and Turkish Cypriot identity in London
No full text<p>This study aims to understand and explain the impact of football on both diaspora formation and the construction/reproduction of ethno-national identities, focusing on constructionist practices in this process. In this context, an ethnographic field study was conducted for six months in an amateur football league established by Turkish Cypriots in London, England. The theoretical framework is modelled on the concept of diaspora proposed by Rogers Brubaker. The study shows that it is possible for a dispersed population to come together in diaspora through football. However, the process is not spontaneous but takes place through the active role of core members. Secondly, the paper provides evidence that football-centred practices of ethno-national identity construction are actively reproduced in a diaspora-specific context through 'core members'.</p>
Functionalized Polyisobutylene and Polyisobutylene-Based Block Copolymers by Mechanistic Transformation from Cationic to Radical Process
No full text<p>The strategy for the preparation of polyisobutylene-based block copolymers via mechanistic transformation from cationic to radical polymerization is reported. This strategy involves the synthesis of 2-bromo-2-methylpropanoyl-terminated difunctional polyisobutylene macroinitiator (BiBB-PIB-BiBB) via consecutive cationic polymerization, in situ preparation of hydroxyl-terminated polyisobutylene and its acylation by 2-bromo-2-methylpropanoyl bromide. The Mn2(CO)10-triggered photo-induced radical polymerization of styrene in bulk using this macroinitiator leads to the formation of multiblock copolymer, while predominantly triblock copolymer is generated during the polymerization of methyl methacrylate. The possibility to functionalize the polyisobutylene by pyrene via photo-induced radical addition of 1-bromomethyl pyrene in the presence of Mn2(CO)10 is also demonstrated in this work.</p>
<p>This study reports a new method for polyisobutylene (PIB)-based block copolymers. It utilizes a difunctional PIB macroinitiator prepared via cationic polymerization and acylation. Photo-induced radical polymerization of macroinitiator with Mn2(CO)10 forms multiblock copolymers with styrene and triblocks with methyl methacrylate. Additionally, this work demonstrates the efficient functionalization of PIB with pyrene moieties via photoinitiated radical addition. image</p>
Effect of abiotic stresses on primary / secondary metabolites and resveratrol in cv. Cabernet-Sauvignon
No full text<p>The research was located at latitude 41° 01’ 11.15” N and longitude 27°<br>
40’ 18.00” E, at an altitude of 60 m above sea level, with 15-year-old<br>
Cabernet-Sauvignon/110R vines over two years. The vineyard has a<br>
planting distance of 2.6×0.9 m, and the vines are trellised to double<br>
cordon Royat. In the vineyard, 4 abiotic stress applications (Shock Action,<br>
Leaf Injury, UV-C) including the Control were applied twice a day<br>
(morning and evening) for 5 days during 3 different phenological stages<br>
(Veraison, Veraison-Harvest, and Harvest). The Leaf Injury was<br>
performed once by striking the leaves with a rod. The Shock Action was<br>
carried out using a plastic hammer, and the UV-C was applied twice a<br>
day for 1 minute. As a result, it was determined that the abiotic stress<br>
did not cause significant differences in primary metabolites such as Total<br>
Soluble Solids (23.69°Brix) and Total Acidity (7.32 g L-1) but had an<br>
increasing effect on secondary metabolites (total tannin, anthocyanin,<br>
TPC, resveratrol). Additionally, it was found that they had an enhancing<br>
effect on the TPI. In terms of resveratrol, the effects of UV-C (0.35 mg kg-<br>
1) and Leaf Injury (0.27 mg kg-1) were noted to be higher than the other<br>
two (Shock Action and Control).</p>
The effect of hot forging on the thermal and mechanical properties of spark plasma sintered SiC-TiB2-B4C Composites with CeO2 Addition
No full text<p>Sintering of SiC-TiB2-B4C composite was carried out by SPS at 1900 degrees C and hot forging was applied at 2050 degrees C to improve mechanical and thermal properties. A fully dense ceramic, with density of 3.08 g/cm3 was obtained after SPS and the properties of the composite improved after hot forging. During SPS sintering, TiB2 and graphite phases were in-situ formed consuming all TiC. Very strong orientation of graphite, coarsening of grain size and reduction in both liquid phase and porosities were observed after hot forging. While fracture toughness increased without compromising hardness and flexural strength, the thermal conductivity was doubled depending on the orientation of the in-situ formed graphite after hot forging. The hardness, fracture toughness, thermal conductivity, elastic modulus and density of the sintered and hot forged composites were measured as 32.2-32.8 GPa, 4.0-4.4 MPa.m1/2, 27.8-58.1 W m-1 K-1, 280-315 GPa and 3.12-3.08 g/cm3 respectively.</p>
Yargı ve Emniyet Mensupları Bağlamında Kadına Yönelik Şiddet
No full text<p>Kadına yönelik şiddet, toplumsal cinsiyet eşitsizliğinin bir sonucu olarak tarihsel süreç içerisinde kendini göstermektedir. Ekonomik İşbirliği ve Kalkınma Örgütü’nün (OECD) şiddet<br>
verilerine göre, Türkiye hem OECD hem de G20 ülkeleri arasında kadına yönelik şiddetin<br>
en fazla görüldüğü ülkedir. Bu bağlamda, araştırmanın amacı Türkiye’de yargı ve emniyet<br>
mensuplarının bakış açısı ile kadına yönelik şiddet olgusunu sosyolojik açıdan incelemektir.<br>
Bu çerçevede, Gaziantep’te görev yapan beş hâkim, beş savcı, beş avukat ve beş polis olmak<br>
üzere toplam 20 yargı ve emniyet mensubu ile nitel araştırma yöntemi kullanılarak görüşmeler yapılmıştır. Araştırmanın temel problemleri; Türk Ceza Kanunu’nda yer alan yasaların<br>
kadına yönelik şiddeti önlemede yeterli olup olmadığı, kadına yönelik şiddette problemlerin<br>
neler olduğu ve kadına yönelik şiddeti önlemede ne gibi çözüm önerilerinin bulunduğudur.<br>
Araştırmanın teorik yapısı, Pierre Bourdieu’nun sembolik şiddet kavramına dayanmaktadır.<br>
Araştırma bulguları, yasaların uluslararası kaynaklı olması nedeniyle yasalarla ilgili herhangi<br>
bir sorun bulunmadığını işaret etmektedir. Bununla birlikte, bu araştırma kadına yönelik şiddet konusunda kadınların mevcut bakış açılarını değiştirmelerinin gerekliliğini vurgulaması<br>
açısından önemlidir.</p>
Sound Source Directivity Estimation in Spherical Fourier Domain from Sparse Measurements
No full text<p>Real sound sources have unique directional properties unlike simple idealised sources such as monopoles. Measur-</p>
<p>ing the directivity patterns of sound sources typically involves measuring sound power using pressure microphones</p>
<p>on a spherical grid surrounding the source. This approach is not very practical and is costly due to hardware</p>
<p>requirements. This paper proposes a reduced-complexity source directivity measurement approach. The spherical</p>
<p>harmonic decomposition of the sound field at a small number of measurement points around the source is first</p>
<p>obtained. Both pressure and its higher-order spatial derivatives are then calculated to estimate source directivity that</p>
<p>best matches a fixed-order model. The proposed approach is validated to assess its utility using eight second-order</p>
<p>measurements around a loudspeaker. The estimated directivity functions closely matched the manufacturer data,</p>
<p>particularly at low and mid-frequency bands.</p>
Türkiye'deki İç Göçlerin Kırsal Alanla Devam Eden Bağları Üzerine Bir Değerlendirme
No full text<p>Bu çalışmada Türkiye’deki iç göç hareketliliği ve kır ve kent alanları arasındaki bağlar incelenmektedir. Türkiye Cumhuriyeti tarihinde göç hareketliliği ülkenin nüfus yapısı ve şehirlerinin temelini oluşturmuştur. Özellikle 1950’lerden itibaren kırdan kente iç göç, büyük şehirlerin sosyoekonomik ve demografik yapısını şekillendirmiştir. İç göçle birlikte kırsal alanlarla çok yönlü kültürel ve ekonomik bağlar sürdürülmüştür. Günümüzde ise hareketlilik kentten kente ve büyük kentlerin çeperlerine doğru yaygınlaşmaktadır. Kırsal alan tamamen terk edilmeyip, yeni kırsallıklar ortaya çıkarken, kentlerin olumsuz koşulları ve artan refah seviyesiyle ikincil ve çoklu mekân tercihleri artmıştır. Çalışma, bu hareketlilikleri geriye göç literatüründen istifade ederek ve güncel verilerle inceleyerek kırsal alanla kurulan bağlardaki değişimleri irdelemektedir. Mekânlar arası hareketlilikler göstermektedir ki, güncel ve dinamik nüfus hareketliliklerini takip edebilmek için Adrese Dayalı Nüfus Kayıt Sistemi gibi mevcut sistemlerin hareketli nüfusu tam olarak ölçmede yetersiz kaldığı görülmektedir. GSM sinyalleri, bankacılık hareketleri ve internet konum verileri gibi yeni teknolojilerin, hukuki düzenlemelerle birlikte, bu hareketliliği daha doğru ölçebileceği muhtemeldir. Özellikle deprem gibi kriz anlarında ikamet verilerinin yetersiz kaldığı ve böylelikle müdahale süreçlerinde aksamaların yaşandığı bir gerçektir. Toplumsal refah artışı ve yaşam kalitesindeki belirli yükselişin, alternatif mekân arayışlarını tetiklediği ve hareketliliğin dinamik ölçümünün dengeli nüfus politikaları için elzem olduğu ifade edilmelidir.</p>
