THE DEVELOPMENT AND MANUFACTURE OF POLYMERIC ENDOPROSTHETIC MESHES FOR THE SURGERY OF SOFT TISSUES
Authors: Zhukovsky Valery , Rovinskaya Ludmila , Vinokurova Tatiana , Zhukovskaya Irina 
Published: December 2023

Abstract
‘Esfil’ endoprosthetic meshes made of polypropylene monofilaments, ‘Eslan’made of lavsan multifilaments and ‘Ftorex’ made of lavsan multifilaments with waterproofing fluoropolymer coating have been developed and manufactured for the plasty of soft supporting tissues after tumour resection and herniotomies, by damage to the abdominal wall and the diaphragm and in other surgical procedures. ‘Esfil’ polypropylene endoprostheses are biologically inert and resist the action of tissue fluids. The hydrophoby and solidity of the threads prevent the meshes from becoming infected. Prompt spreading of the fibroblasts along the filaments promotes the reparation of soft tissues. The ‘Eslan’ meshes are substantially softer and can be used when so-called ‘gentle’ implants are required. However, the capillarity of lavsan filaments may cause wound infections. The ‘Ftorex’ prostheses do not suffer from this disadvantage, due to impregnation of the pores between multifilaments with fluoropolymer. At the same time, the manipulation properties of the prostheses remain stable and their biocompatibility and bioresistance increase. Physico-mechanical, medical, biological and clinical tests allowed us to determine the optimal knitting structures of the endoprostheses we developed.

Abstract
A feasible possibility exists of generating longitudinal loads in the form of tension pulses during the processing and use of visco-elastic linear textile products. The propagation of such pulses can be accompanied by hitherto unexamined phenomena different from those occurring over the time of static loading; among other such, the phenomenon of potential destruction can appear. The genera5on and propagation of tension pulses in a linear textile object fastened between two insuperable barriers are discussed in this work. The investigation's results allow us to state that during the time of tension pulse propagation, the selection of the tension pulse (which is only one of the longitudinal loads acting on a linear textile product) is fully justified. The destruction of thread can be accompanied with tension pulse propagation, but in contrast to other typical longitudinal loads, this destruction can differ along the whole length of the pulse. Under conditions of repeated one-directional pulse stimulation, and considering the attenuation of this forcing, a linear aniso-destruction of the tread can appear as the result of its destruction. In the case when only one insuperable barrier exists, two different zones of potential destruction of the linear textile product will occur, whereas three different zones are observed with two barriers.

Published: December 2023

Abstract
Polymeric optical fibre (POF) is used for simple light guide and illumination applications. The polymer optical fibre materials can be utilised in flexible lighting elements which can be combined with textile structures. The POF woven fabrics are introduced as a flexible alternative to lighting elements. Various light-emitting woven fabric and light emission theories has been discussed. Simple polymethyl- metacrylate PMMA and polycarbonate PC fibres have been produced experimentally through single-screw and conical extrusion. The fibre is integrated in woven structures by means of handloom, narrow fabric weaving and Jacquard technology. The manufacturing technology suitable for lightemitting textile applications and its opportunities in textile integration is discussed.
VORTEX SPUN YARN VS. AIR-JET SPUN YARN
Authors: Basal Guldemet , Oxenham William 
Published: December 2023

Abstract
Vortex spinning can be viewed as a refinement of jet spinning, or a natural development in fasciated yarn technology. As in all other fasciated yarns, the structure of vortex yarn consists of a core of parallel fibres held together by wrapper fibres. This has been revealed by examining an untwisted vortex yarn sample under the Scanning Electron Microscope. Subsequently, the physical properties of vortex and air-jet yarns produced from different polyester cotton blends were compared. Results indicated that vortex yarns have tenacity advantages over air jet yarns, particularly at high cotton contents.
EXPERIMENTAL DETERMINATION OF THE TENSILE FORCE IN EMBROIDERY THREADS KNITTING
Authors: Hadzhidobrev Peter , Charalambus Andreas 
Published: December 2023

Abstract
In this work, a method for indirectly determining the tensile force in yarn of twisted units is propounded on a tensile force-elongation diagram. The elongation occurs in the change of the screw line step of the twisted units. The screw-line step is calculated after multiple measurements of short-length areas in the work zone of the knitting needles. The measuring is possible for knitting in producing conditions and in real time.

STUDY OF EFFECT OF SPINNING PROCESS VARIABLES ON THE PACKING DENSITY OF RING, ROTOR AND AIR-JET YARNS USING THE TAGUCHI METHOD
Authors: Kumar Akshay , Ishtiaque S. M. , Salhotra K. R. 
Published: December 2023

Abstract
The effect of lap hank, card draft, draft/doublings and drafts at speed frame, ring frame, rotor and air-jet on packing density parameters were analysed using the Taguchi method. The trends of change in packing density with process variables are opposite to those of the yarn diameter and helix angle of the ring, rotor and air-jet yarns studied. The packing density is found to be the highest in air-jet yarn and the lowest in rotor yarn. An increase in draft in the air-jet and a decrease in the rotor spinner increases the packing density of the respective yarns.
INVESTIGATION INTO THE PERIODICITY OF MASS VARIATION OF YARN AND ITS EFFECT ON FABRIC APPEARANCE
Authors: Addisu Ferede , Abdul Hameed Peer Mohamed 
Published: December 2023

Abstract
The appearance of a fabric can be greatly affected if the yarn has a sufficiently pronounced periodic component. The severity of the periodic fault can only be estimated if its intensity is quantified. Even though a spectrogram is more reliable than other tools at determining periodicity, it gives only the resolved mass variation, which may not be present in the final yarn when different faults are superimposed. The relative index of irregularity of yarn is considered as a measure of the intensity of a periodic fault of a spun yarn. By correlating the above index with the relative unlevelness indices of finished fabrics knitted from yarn samples produced at different levels of roller eccentricity, we have established the threshold value of the relative index of irregularity of yarn which produces worse appearance values in the fabric.

Published: December 2023

Abstract
This work is mainly focused on the characterization of physical, low-stress mechanical and surface properties (such as bending rigidity, shear rigidity and air permeability) of plasma coated wool fabrics. A thin film was deposited on fabric samples by means of plasma polymerization of hexamethyldisiloxane (HMDSO) and differences between such plasma-treated and untreated fabrics were evaluated, analysing possible influences of operating conditions (particularly discharge power and deposition time) on the trends of the studied properties.
TEXTILE COMPOSITE MATERIALS FOR SMALL INTESTINE REPLACEMENT

Published: December 2023

Abstract
Down to the present day there are no sufficient techniques for a small intestine replacement, mostly because of the high standards for such implants. An indication for the need of novel operation techniques is the small patient survival rate of just 80 % for isolated small intestine transplantation and 62 % for combined liver-small intestine transplantation. The five year survival rates of the patients are merely 42 %. In order to overcome these limitations the authors are developing a partly resorbable textile-foam-composite for small intestine replacement The novel implant consists of a non resorbable textile PVDF mesh which is foamed with a micro porous, resorbable, and drug loaded polymer. The resorbable polymer serves on the one hand as initial sealing, therefore no intestine substance and bacteria can leak out into surrounding tissue, on the other hand it needs to be micro porous in order to ensure cell ingrowth. For the macro porous textile mesh warp knitting technology is used. The warp knitted tubular structure remains inside the body as a long term implant and provides mechanical support to ingrowing cells. In order to evaluate biomechanical properties of the warp knitted tubular PVDF meshes to compare them to the mechanical characteristics of small intestine tissue, tensile tests were conducted. Results of tensile tests on warp knitted structures with three different loop densities of 8, 12, and 16 loops per cm were compared to tensile tests on native small intestine tissue probes. The recorded curves of small intestine and warp knitted structures showed similar characteristics. The two characteristic Young Modules as well as the curve progression of the warp knitted structure with 12 loops per cm showed good accordance to the values of the native small intestine. Morphological analysis of the textile structures by digital image processing showed adequate pore size and porosity of the textile mesh.

EFFECT OF THREAD STRUCTURE ON TENSION PEAKS DURING LOCK STITCH SEWING
Authors: Rengasamy R. S. , Wesley D. Samuel 
Published: December 2023

Abstract
A dynamic sewing tension study was carried out with a tension probe on sewing threads with different structures, physical and tensile characteristics in a single needle lock stitch sewing machine. The needle thread recorded four major tension peaks corresponding to events occurring during sewing; bobbin thread withdrawal, stitch tightening, needle piercing the fabric and tightening of the needle thread around the shuttle, among which stitch tightening caused the maximum tension for all threads. Polyester filament and spun polyester threads exhibited the highest and lowest tightening tension, respectively. Multiple regression analysis showed that pre-tension and elastic modulus show positive influences while tex, bending, rigidity and compressibility of threads show negative effects on tension peaks during tightening and needle piercing. Sewing speed shows a positive impact only on the tension peak due to needle piercing. Pre-tension showed a prominent influence on tension peaks on all threads while the number of fabric layers failed to show any effect.
Evidences and therapeutic advantages of donanemab in the treatment of early Alzheimer’s disease
Authors: Shukla Ajay Kumar , Misra Saurav 
Published: December 2023

Abstract
The humanised monoclonal antibody donanemab is being developed to treat early onset Alzheimer’s disease (AD). This drug targets N-truncated pyroglutamate amyloid-peptide at position 3 (N3pG), a modified form of deposited amyloid-peptide. The symptoms of Alzheimer’s disease include gradual memory loss and other cognitive impairments. This disease is characterized by amyloid plaques, which are formed as a result of an accumulation of amyloid-(A-β) peptides. Despite granting donanemab breakthrough therapy designation in June 2021, the FDA rejected donanemab’s accelerated approval application in January 2023, due to inadequate safety data. According to the baseline amyloid level, the time to achieve plaque clearance (amyloid plaque level <24.1 centiloids) varied. Patients with higher baseline levels were more likely to achieve amyloid clearance. The safety of the drug was demonstrated by amyloid-related imaging abnormalities (ARIA), which ranged from 26.1 to 30.5 % in the studies. Clinical trial results have shown that donanemab delays cognitive and functional deterioration in patients with mild to moderate AD. However, it is not yet known whether donenameb offers therapeutic benefits that can change and improve the clinical condition of AD patients. To achieve significant clinical benefits in AD patients with cognitive impairment, further studies may be needed to investigate the interaction between A-β plaque reduction and toxic tau levels.

Published: December 2023

Las ciudades inteligentes y sostenibles se perfilan como la respuesta a los desafíos actuales de las áreas urbanas y, en consecuencia, como la senda hacia la mejora de la calidad de vida de sus habitantes. No obstante, el desarrollo de estas urbes no es uniforme, sino que se moldea según las particularidades de cada territorio, donde la gestión pública desempeña un papel fundamental en la configuración del desarrollo inteligente de cada comunidad. En este trabajo, presentamos los resultados de un estudio de caso aplicado a Heredia, Costa Rica, con el propósito de identificar las características del modelo de gestión pública de la ciudad y determinar su impacto en el desarrollo inteligente de su territorio. El enfoque teórico y metodológico se sitúa en el contexto de la Nueva Gestión Pública y los modelos de gobernanza de la era digital y la gobernanza pública inteligente. Mediante el análisis minucioso de los planes de desarrollo a largo plazo del gobierno local y la aplicación de un Índice de Ciudades Inteligentes y Sostenibles, se identificó la estrecha interconexión entre el estado actual de Heredia como una ciudad inteligente y la manera en que se administra el gobierno local. Entre los principales descubrimientos, destaca la influencia directa que ejerce la gestión pública del gobierno local de Heredia en el desarrollo de su ciudad inteligente, ya que, las áreas en las que no se implementan acciones adecuadas se presentan como desafíos para el progreso de la ciudad inteligente, lo que nos lleva a concluir que su modelo de gestión ha sido un factor determinante en su desarrollo inteligente. Asimismo, se identifican dos modelos diferentes de gestión pública dentro del contexto de Heredia, los cuales impactan de manera significativa en la evolución de la ciudad hacia la inteligencia urbana.

Published: December 2023

O processo de envelhecimento é gradual, natural e atinge o indivíduo de maneira diversa a depender das relações construídas ao longo do tempo, das práticas corporais e do estilo de vida. A população idosa tem aumentado consideravelmente e junto a ela cresce também o risco de quedas decorrente da perda funcional que ocorre no organismo durante este processo que pode se apresentar de maneira mais ou menos limitadora a depender de vários fatores de risco como as doenças crônicas degenerativas ou fatores de proteção como o exercício físico. Diante disso, o objetivo da pesquisa em tela foi verificar a relação entre a funcionalidade e a ocorrência de quedas no idoso observando qual é a relação direta da capacidade funcional do indivíduo e o histórico de quedas. Esse estudo foi realizado a partir de uma pesquisa bibliográfica narrativa da literatura nas bases de dados SciELO (Scientific Electronic Library Online) e Google Acadêmico a partir das palavras-chaves: idoso, capacidade funcional e queda. Os estudos examinados permitiram concluir que existe uma correlação positiva direta entre a capacidade funcional comprometida e o risco de queda, ou seja, quanto mais dependente em relação a funcionalidade cotidiana maior o risco de cair.

Innovation as a Tool to Improve Public Service Delivery: South African Government Perspective
Authors: Thusi Xolani , Mahlatse Ragolane , Matyana Mandisi 
Published: December 2023

AbstractSouth African citizens are still facing problems of poor service provision in the local, provincial, and national governments after 28 years of democracy. The standard of public service provision and implementation in South Africa is deteriorating. It is important to note that due to the country's high level of unemployment, the majority of South African citizens rely on government service provision. Because of the government's inability to reach every citizen with efficient and effective service provision, South Africa has the highest level of inequality and a huge gap between the rich and the poor, making efficient service provision a solution to bridge the gap and inequality. This article proposed that the government must develop techniques to boost innovation in the public sector to prioritize service delivery in the country, as there are many challenges surrounding the South African public sector. Qualitative approach was adopted in this research, through the review of recent secondary sources to address the objectives of this study.Keywords: Citizens, Government, Innovation, Service Provision.

Published: December 2023

This study aims to explore the impact of an anti-corruption education course on the perception of anomie among 358 undergraduate students from two public universities. The study adopted a mixed-methods research design. The experimental group received a six-week anti-corruption education course comprising video-based modules while the control group received no intervention. Participants' perceptions of anomie were assessed using pre- and post-test surveys. Additionally, semi-structured interviews were conducted with a subset of participants from the experimental group. Two-way repeated measures analysis of variance and interview transcript thematic analysis were both used to analyse the data. The results demonstrated a significantly greater decline in anomie over time in the experimental group compared to the control group. Thematic analysis of the interview data provided further insight into participants’ understanding of the negative consequences associated with corrupt practices. The results demonstrate that the anti-corruption intervention is helpful in reducing students' unethical attitudes and strengthening their commitment to moral conduct. Participants in the course provided positive reviews. Additionally, they shared that their viewpoints on different facets of corruption had undergone some changes. The results of this study have practical implications for both researchers and practitioners in the field of anti-corruption education.

Authors: Baisarinova Aigerim , Toleubekova Rymshash 
Published: December 2023

Understanding factors affecting student academic and life outcomes may be critical for social work programs and educational institutions. Therefore, this study aims to explore the relationships between resilience, technostress and reflective capacity among social work students. A cross-sectional non-experimental research design was used. One hundred and sixty-three social work students completed an online survey measuring technostress level, reflective capacity and psychological resilience. Data were analyzed using Pearson’s to estimate linear correlations, confirmatory factor analysis to ensure model fit and structural equation modeling with covariates to reveal the relationships between the measured constructs. The results indicated that resilience had a direct and negative effect on technostress, a positive and direct effect on reflective capacity and a negative indirect effect on technostress through reflective capacity. This means that social work students with higher levels of resilience had lower levels of technostress related to technology use were more likely to engage in reflective practices and had lower levels of technostress due to improved reflective capacity. These findings emphasize the significance of resilience and reflective practices in mitigating the negative effects of technology use among social work students. However, researchers should be cautious about generalizing findings due to the sample’s limitations and future investigations should consider longitudinal data from diverse populations.

Published: December 2023

Abstract
Soil erosion is a severe problem posing a number of adverse effects on the environment. It is a prominent hazard damaging the fertile agricultural land. Therefore, in this study, a spatio-temporal assessment of soil erosion was carried out in the Swat River Basin, Pakistan by employing the Revised Universal Soil Loss Equation (RUSLE). The parameters of the RUSLE model are rainfall erosivity, soil erodibility, slope length and steepness, land management and support practice. These factors were developed from monthly mean rainfall data obtained from the Regional Metrology Department Peshawar, FAO soil database, land use data prepared from Landsat-5 and 8 satellite imageries, topographic data obtained from the ALOS PALSAR Digital Elevation Model (DEM). The analysis discovered that 13% of the study area experienced severe erosion. Results of the spatial distribution and vulnerability to erosion within the Swat River Basin have been categorized into different zones such as very low (59.7%), low (19.5%), moderate (5.37%), high (6.86%), and very high (5.96%). These results accentuate the necessity for mitigation measures in the study area to mitigate the loss of valuable topsoil. This research possesses the potential to offer valuable insights into decision-making and planning to reduce the risk of erosion.
