Abstract
Electrospinning (ES) is a versatile and diverse technique to fabricate nano and micro fibers that could be utilized as drug delivery systems. The aim of this research was the fabrication and characterization of drug loaded nanofibrous scaffold produced by single-needle ES using poly(Ɛ-caprolactone) (PCL) and poly(ethylene glycol-400) (PEG) and to investigate the potential of this material as a drug delivery system. A model drug, Ibuprofen (IBU), was used. Ibuprofen is a medicine that is a non-steroidal, anti-inflammatory drug (NSAID). Two concentrations of IBU, 5 wt% and 7 wt%, were incorporated for the ES of PCL and PCL/PEG nanofibers. Characterization of nanofibers was done by using Scanning Electron Microscopy (SEM), Differential Scanning Calorimeter (DSC), Thermogravimetric Analysis (TGA), and Water Contact Angle Measurements. The impact of IBU on nanofibers’ properties such as morphology, diameters, hydrophilicity, and tensile strength was investigated. Finally, the drug release kinetics of IBU from nanofibers was analyzed and their percentage release efficiency of IBU (RE%) was determined by UV-vis spectroscopy during 24 h.
A Novel Foam Coating Approach to Produce Abrasive Structures on Textiles
Authors: Kenttä Eija , Kumar Vinay , Andersson Petter , Forsström Ulla 
Published: September 2021

AbstractAbrasive materials are classified as paper, nonwoven, or plastic-based multilayer structures, which are used for different kinds of surface finishing. Currently, the production of abrasive structures on textiles is carried out by spraying a slurry of binder and abrasive particles, e.g., Al2O3or SiC, with subsequent drying and curing of the binder. The drawback of this production method is the poor runnability of the spraying process. Even small variations in the process parameters may lead to an uneven coating. Therefore, a novel coating approach was developed to produce abrasive structures with foam coating on textile substrates. The foam coating method, which is commonly used in the textile industry, has the potential to produce an even coating layer. The runnability and reliability of the foam coating process are good even with high solids. From a workplace safety perspective, another advantage of foam coating is that there are no airborne particles during the coating process. A polyamide woven cloth was foam coated with an aqueous slurry containing abrasive grains (SiC), a water-based UV-curable acrylate binder, and cellulose nanocrystals (CNCs) to adjust the slurry rheology. Stable abrasive-binder foams were generated from the slurries even at high solids of 50% using an anionic foaming agent. The cloth was foam coated and dried, and the resin was cured with a LED-UV lamp on a pilot scale. It was observed that without the addition of CNC the foam did not stay on the surface of the cloth after coating. CNC acts as a rheology modifier and co-binder, which prevent the foam from penetrating deeper into the pores of the cloth. CNC also acted as a dispersing agent: the slurry was effectively stabilized by the CNC to prevent sedimentation of the abrasive grains. An organic solvent-free composition was introduced by combining CNC with a water-based UV-resin.
Planning for Sustainable Developmentof Tourism in the Tatra National Park Buffer Zone Using the MCDA Approach
Authors: Adamczyk Joanna , Wałdykowski Piotr 
Published: September 2021

AbstractThis study aims to develop practice guidelines for the preparation of local regulations promoting sustainable tourism planning for the area located at the entrance to the Tatra National Park, Poland. Included in the study was a set of tourism activities put forward by the local community. These activities were divided into two priorities: sustainable tourist activities (hiking and walking, cycling, horseback riding) and investments that would have an environmental impact (downhill skiing, recreational infrastructure, commerce, catering). The analysis criteria covered the tourist attractiveness of the area and its suitability for a given activity (benefit), as well as requirements concerning the protection of nature, topographical relief, landscape, and traditional land use (cost). These criteria were evaluated using the Analytic Hierarchy Process (AHP) and summarized using the Weighted Linear Combination (WLC). The results showed the high attractiveness of the area for both priorities. However, due to the area's unique nature, investments having an environmental impact must be limited to the vicinity of the existing built-up areas. The use of MCDA supports decision-making at the local scale, significantly enhances the transparency of the results, and facilitates communication with local communities. The comparison with the current local law provisions showed the shortcomings of the methods used to date when preparing planning instruments.

Abstract
Gullies and other forms of erosion have been the greatest environmental problem and catastrophe in most high- and low-income countries. The challenge posed by soil erosion has compromised agricultural productivity, environmental biodiversity and food safety for the world's population. It is important to identify vulnerable areas to soil erosion in each region to initiate remedial measures. This study demonstrates the use of watershed morphometry coupled with weighted sum analysis (WSA) to estimate the soil erosion susceptibility of the Imo River Basin sub-watersheds (SWs) in South-Eastern Nigeria using satellite remote-sensing data and geographic information system (GIS) analysis. To this end, Shuttle Radar Topography Mission (SRTM), a Digital Elevation Model (DEM) with 30 m spatial resolution was used to extract and analyse 18 morphometric parameters including basic, linear, shape and relief. The method of receiver operating characteristics (ROC) curves was used to validate the model's prediction accuracy. This morphometry-based analysis resulted in the SWs being classified into zones of low, medium, high and very high erosion susceptibility. With regard to erosion susceptibility, 41.51% of the basin (2494.68 km2) is in the very high priority zone; while 10.50%, 44.33% and 3.66% of the basin are in the high, medium and low priority zones respectively. Validation of the final erosion susceptibility map showed a prediction accuracy of 81%. The use of satellite imagery and morphometric analysis in this study was cost- and time-effective for identifying areas susceptible to soil erosion.

Digital Influencer e Conteúdo Congruente gera Oportunidade para Presente: Estudo sobre a decisão de compra dos pais
Authors: Galdino da Silva Júnior Omero 
Published: September 2021

O presente artigo objetiva compreender melhor a relação entre a influência digital de usuários e a avaliação dos pares como variáveis favoráveis ao consumo de produtos. Dessa forma, foi estruturada uma pesquisa experimental com foco em analisar de que forma se dá a relação entre esses construtos. A partir de uma amostra não-probabilística por conveniência, usando a técnica snowball (Cozby & Bates, 2012), participaram 89 pais de todos o Brasil nessa pesquisa. O estudo contribui com a literatura ao entender que os digital influencers podem até possuir um apelo positivo para a intenção de compra, mas ainda não se obteve correlação efetiva para a compra efetiva. Contudo, a validação desses usuários tem sido e será cada vez mais crucial para a tomada de decisão dos compradores (Kotler, Kartajaya & Setiawan, 2017).

Ronco do V8 Objeto de Desejo: Estudo de Caso do Automóvel Ford Maverick em Diferentes Gerações sob a Ótica das Cadeias Meio Fim
Authors: Levrini Gabriel , Borba da Silveira Alexandre 
Published: September 2021

No início do ano de 1970, a Ford do Brasil S.A., trouxe um campeão de vendas dos USA, o Ford Maverick. O automovel caiu rapidamente no gosto popular, neste novo segmento de carros médios, passando a ter uma legião de admiradores. Esta pesquisa objetiva, a luz da teoria das cadeias meio-fim, comparar o comportamento e valores de usuários do Maverick de duas diferentes gerações em épocas diferentes: nos anos 70 quando o automóvel foi lançado, cujos principais consumidores eram da geração Baby Boomers e dos filhos de esta geração, a geração X. Para este estudo foi utilizado a técnica de laddering, com entrevistas em profundidade com 47 entrevistados, sendo 20 pertencentes a geração Baby Boomers (indivíduos nascidos entre 1940 e 1960) e os outros 27 entrevistados, nascidos entre 1970 e 1990 que fazem parte da geração X, em que seus depoimentos permitiram acomparação das gerações. Os resultados da análise de conteúdo e da análise utilizando o laddering permitiu o desenvolvimento de mapas hierárquicos dos valores respectivos de cada geração. Estes mapas deram como resultado: a geração Baby Boomers demostrou como valor fundamental para a aquisição do Maverick na época a questão da segurança financeira e motor potente V8 como maior fator motivacional para aquisição deste automóvel. No caso da geração X o estudo indicou como esperado, o valor nostalgia e saudosismo como maior impulsionador para ainda ter este automóvel, seja como colecionador ou hobby. As gerações apresentam como em comum, o valor de nostalgia e saudosismo. Os resultados sugerem novas abordagens para os estudos do comportamento de consumo e marketing geracional.

Purpose: To evaluate the efficiency of glutamine in the prevention & treatment of mucositis in head and neck cancer patients undergoing chemoradiation.
Material and Methods: Forty patients of histologically proven head and neck carcinomas undergoing chemoradiation with Conventional Radiation on telecobalt and concurrent Cisplatin were randomised into 2 groups. The study group received oral glutamine solution 2 hours prior to undergoing radiotherapy on all days of treatment. The severity and duration of mucositis were recorded once every week using WHO and RTOG grading system for all patients undergoing treatment.
Results: Glutamine lead to a delay in the onset of mucositis. The overall incidence of grade mucositis was significantly low in glutamine arm (22% vs 55%, p= 0.006). On weekly assessments, the incidence of grade mucositis in study arm compared to the control was 0 vs 30%, p=0.02 at 4 weeks, 15.8 vs 45%, p= 0.038 at 5 weeks and 22 vs 70%, p=0.001 at 6 weeks. However, there was no statistically significant difference in the incidence of grade 1 and 2 mucositis in both arms.
Conclusion: Use of oral glutamine reduces the incidence and duration of oral mucositis and hence helpful in the prevention and treatment of oral mucositis with good compliance and further result in good locoregional control of the disease.

Published: September 2021

Background: Intensity-modulated radiotherapy (IMRT) for nasopharyngeal carcinoma (NPC) acts on the tumor and affects surrounding organs at risk (OARs). This study aimed to quantify the geometric changes in the parotid gland, the submandibular gland (SMG), and the thyroid, during the course of treatment. Methods: Twenty patients diagnosed with locally advanced NPC were consecutively enrolled, and received definitive chemoradiotherapy in 33 fractions over 6.5 weeks. Each patient underwent planning computed tomography (pCT) followed by six weekly repeat CTs (rCTs) without contrast enhancement. Each rCT was rigidly registered to its pCT. Changes in terms of volume, position, and shape of the OARs were assessed. Differences in left- and right-sided OARs were compared. Results: Radiation doses to the parotid, SMG, and thyroid were 32.12 ± 11.2 Gy (mean ± standard deviation SD), 25.46 ± 8.62 Gy, and 18.89 ± 10.24 Gy, respectively. Volume reductions of 28.6% ± 14.6% (mean ± SD), 26.6% ± 17.1%, and 12.3% ± 11.3% were observed in the parotid, SMG, and thyroid, respectively. Rate of volume loss for the parotid and SMG decreased from 1.6-1.7% per day in the first week to 0.5%-0.6% in the last week. Contrarily, not all thyroid lobes decreased in volume during treatment. The center of mass of the parotid shifted 2.0-2.6 mm medially; for the SMG and thyroid, a 0.1-0.5 mm medial shift was noted. The displacement in the anterior-posterior and cranial-caudal directions was < 0.6 mm. The 3-dimensional vector displacements of the parotid and SMG were 2.2-2.9 mm, and that of thyroid was 4.0-4.3 mm. The overlapping metrics of all three OARs decreased over time, and the shortest perpendicular distance increased from 1.5-1.8 mm in the first week to 2.4-2.5 mm in the last week. The geometric differences between weeks were statistically significant (P<0.05). Conclusions: The volume, position, and shape of the OARs changed significantly during IMRT for NPC. These geometric changes displayed a time association, suggesting the necessity to re-plan treatment for better sparing of these OARs.
