Many industrial activities contribute to environmental pollution by causing these problems. Therefore, it is of great importance to develop environmentally friendly production methods, reduce resource consumption and minimize environmental impacts. The yarn dyeing industry is a sector where natural resources are used intensively and environmental pollution problems are seen. Innovations in this sector aim to make production methods more sustainable. In particular, process reduction is an important step in reducing resource consumption and minimizing environmental impacts. This provides an important opportunity to conserve natural resources and produce environmentally friendly products. Therefore, with the increasing demand for ecological products, it is aimed to develop an environmentally friendly, sustainable and environmentally sensitive process in yarn dyeing. With the new process developed within the scope of the project, a dyeing study was carried out using the natural color of raw cotton yarn. The first bath pre-treatment we apply to raw cotton yarn allows us to make homogeneous dyeing. Thus, it was possible to reduce the need for some chemicals and natural resources that are harmful to nature. The new process developed within the scope of the project is gaining importance in the textile industry due to limited natural resources and increasing environmental problems. The aim of the project is to reduce the use of water, energy and chemicals by eliminating the bleaching step used in traditional yarn dyeing processes and to create an environmentally friendly product platform. In this way, with the increasing demand for ecological and sustainable products, customer expectations can be met and the company's environmental impact can be reduced. In addition, this new process, which saves energy and water, offers the opportunity to gain a competitive advantage by providing cost savings in the textile industry. Therefore, the new process developed sets an example for other businesses in the sector, benefiting both the environment and the operation of the company.","PeriodicalId":511802,"journal":{"name":"Advances in Science and Technology","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140366159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, polymer film patches were developed using a mixture design methodology, incorporating polyvinyl alcohol (PVA), polyvinyl pyrrolidone (PVP), glycerol (GLY), and deionized water (DW). To investigate the impact of the mixture on patch viscosity, seventeen different mixtures were designed using extreme vertices and were prepared through a simple casting technique. The special quartic model proved to be the most suitable for explaining the relationship between ingredients and predicting viscosity, as it demonstrated impressive statistical performance with a standard deviation of 296.237, an R-squared value of 99.80%, and a mean absolute percentage error of 4.24%. To validate the accuracy of our viscosity predictions, five mixture ratios were randomly selected from the contour plots, resulting in a mean absolute percentage error of 7.71%. In evaluating viscosity and mixture ratio, PVA demonstrated a significant influence compared to other constituents. Higher levels of PVP correlated with increased viscosity, whereas increased GLY concentration led to decreased viscosity. Additionally, the impact of GLY on viscosity diminishes with higher concentrations of PVP and PVA, aligning with the antagonistic terms PVP*GLY and PVA*GLY. Furthermore, antagonistic behavior was observed for the PVA*DW interactions, while synergistic tendencies were observed for the PVA*PVP interaction.","PeriodicalId":511802,"journal":{"name":"Advances in Science and Technology","volume":" 1051","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140382300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The utilization of synthetic polyvinyl alcohol (PVA) as the base material to construct electrospun nanofibers is often related to the limitation of biological function. Therefore, in this study, elastin (EL), a natural polymer, was incorporated into PVA matrix to overcome the biofunctional limitation. The ideal electrospinning parameters for the fabrication of PVA/EL electrospun nanofibers were investigated by varying the compositions of PVA/EL at 9.9/0.1, 9.5/0.5 and 9.0/1.0 (v/v) and the applied voltages at 18, 20 and 22 kV. With the increasing voltage from 18 to 22 kV, the mean fiber diameter decreased for the PVA and PVA/EL of 9.9/0.1 (v/v) while a fluctuating trend was observed for the 9.5/0.5 and 9.0/1.0 (v/v). The homogenous nanofibers construction with no beads was observed in the PVA/EL 9.5/0.5 (v/v). Both PVA and PVA/EL nanofibrous membranes displayed hydrophilicity with water contact angles below than 90°. In conclusion, the PVA/EL 9.5/0.5 (v/v) fabricated at 20 kV, possessed the ideal fiber morphology and wettability, to be subjected for biomedical applications.","PeriodicalId":511802,"journal":{"name":"Advances in Science and Technology","volume":" 61","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140384456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One such alternative under investigation is the utilization of biodegradable nanofiber membranes, fabricated using an electrospinning method. In this study, polycaprolactone (PCL) was used as the main matrix to form electrospun membranes at different electrospinning parameters with the incorporation of estradiol to address bone regeneration capability. The effects of estradiol incorporation within the PCL membranes while determining the appropriate electrospinning parameters through morphological, chemical functionalities and wettability analyses were investigated. The inclusion of estradiol into the PCL matrix has reduced the nanofiber diameter and improved the wettability properties of the membranes. The alterations of electrospinning voltage and flow rate also impacted on the reduction of fiber diameter and wettability, which highlights the membrane’s potential for further cell attachment and bone regeneration.","PeriodicalId":511802,"journal":{"name":"Advances in Science and Technology","volume":" 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140383664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When a sphere rolls on a plane, the axis of rotation is undefined, and the amount of rotation is unlimited. Therefore, the conventional Euler angular representation for pose estimation produces singular points (gimbal locks), and a continuous pose representation is not possible. In this paper, we propose an algorithm that incorporates micro-quaternions to achieve continuous posture representation, even at singular points.

{"title":"The Development of Artificial Saliva with Oral Wound Healing Property","authors":"S. Thaweboon, Ratchaporn Srichan, Supaporn Mala, B. Thaweboon","doi":"10.4028/p-wc6acn","DOIUrl":"https://doi.org/10.4028/p-wc6acn","url":null,"abstract":"Wound healing is a normal biological mechanism of the body that helps to maintain the integrity of the tissue. In this process, fibroblasts play an important role in supporting wound healing by migrating to the injury site and laying down a new extracellular matrix. Oral wounds heal more rapidly than skin wounds due to the presence of saliva. However, a reduced salivary flow rate or hyposalivation is frequently found in some patients due to their systemic conditions or intake of various medications. In order to control or treat hyposalivation, the use of artificial saliva is recommended for these patients. Various agents were added to artificial saliva to improve its properties. The aim of the present study was to investigate the effect of artificial saliva containing vanillin on the wound healing of human gingival fibroblasts by inducing cell migration in vitro. Human gingival fibroblasts isolated from human gingiva were purchased from Scien Cell Research Laboratories, USA. The migratory ability of fibroblasts was performed on a confluent monolayer by the wound healing scratch assay. Artificial saliva with different concentrations of vanillin (0.12% to 4% w/v) was added and incubated for 24 h. Artificial saliva without vanillin was used as a control. The migration cells were fixed with 25% methanol and 0.2% toluidine blue. In vitro cell migration to the wound area was determined by photographing with an inverted microscope coupled to a digital camera (Nikon D 5100). In the presence of 0.25%, 0.5%, and 1% w/v vanillin-containing artificial saliva, human gingival fibroblasts had a significantly higher potential to migrate into the wound area than a control (p-value <0.05). Data from this study provides the first scientific evidence to demonstrate the benefits of using artificial saliva containing vanillin to maintain healthy gums and accelerate oral wound healing. Rinsing the mouth with this artificial saliva is recommended as the most preferable method for moistening and lubricating the mouth and facilitating the healing of oral wounds in patients with hyposalivation.","PeriodicalId":511802,"journal":{"name":"Advances in Science and Technology","volume":" 817","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140382842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
