Abstract
The Navier–Stokes equations and the energy equation are used to investigate a fluid flow between two stretching rectangular surfaces subjected to a temperature difference that affects the dynamic viscosity and thermal conductivity of the fluid. The wall stretching process enhances the momentum boundary layer thickness which slows the axial motion of the fluid away from the flow boundaries. When the stretching parameter γ is equal to 1, that is the case corresponding to symmetric stretching, the minimum of the axial velocity is located at the midplane of the channel y = 0.5 if the viscosity variational parameter α equals 0. This minimum moves towards the region 0.5 < y < 1 for α > 0, but migrates towards the region 0 < y < 0.5 for α < 0. Moreover, in the case of symmetric stretching corresponding to γ = 1, the growth in Reynolds number Re tends to increase the axial velocity around the middle of the channel for α ≥ 0 in the attempt to counteract the effects of enhancing the momentum boundary layer thickness leading to the flattening of axial velocity profiles for Re ≥ 100. While the conductivity variational parameter β does not influence enough the fluid dynamics and heat transfer, the Reynolds number Re and the Péclet number Pé can increase or decrease the temperature distribution inside the channel depending on the sign of the parameter α. Practical applications related to the present study include lubrification, food manufacturing, paint industries, extrusion processes in plastic and metal industries.

The Surfaces of Interiority: What Do Women Dream about in European Socialist Cinemas of the 1960s?
Authors: Paranyuk Viktoria 
Published: July 2024

This audiovisual essay investigates cinematic interiority by engaging more than a dozen European socialist films that center on female characters whose behavior in one way or another doesn't conform to societal norms. Since inner activity can never be fully legible, expressions of interiority have a transgressive quality in a society that prized the collective above the individual and prescribed transparency as a key aspect of a film aesthetic. The moments of such cinematic nonconformity can be understood as zones of defiance, which we are able to access, in addition to narrative and other linguistic tools, through cinema's affective affordances. Thus, the video suggests that cinema is uniquely suited to represent inner life through its ability to evoke aural and visual textures and appeal to the senses.

Green coconut water is rich in nutrients and widely consumed in the world. However, the consumption of coconut water out of good practices for food production treat consumer health. The aim of this work was to evaluate the microbiological quality of coconut water sold by vendors street in Sobral - CE. Samples of fresh coconut water were collected bimonthly from four different points (named A, B, C and D) during 12 months (n=24). Samples were characterized by quantification of total coliform (TC), thermotolerant coliform (TTC) and mesophilic aerobic bacteria (MAB). The Most Probable Number (MPN) and Pour Plate techniques were applied to quantification of TC and TTC, and mesophilic aerobic bacteria (MAB), respectively. All samples presented contamination by TC, TTC and MAB. TC-MPN ranged from 4.97x104 MPN/mL to 1.18x105 MPN/mL, and TTC-MPN ranged from 8.39x102 MPN/mL to 1.28x103 to MPN/mL. Samples C and D presented contamination by Escherichia coli. The number of MAB ranged from 3.12x104 CFU/mL to 6.73x104 CFU/mL. TTC number are above of the permitted values according to National Health Surveillance Agency (ANVISA), being considered as unsuitable for human consumption. Then, it is necessary to adopt preventive measures and good hygiene practices in coconut water commercialization for improvement of the microbiological quality of the product and prevent risks to consumers health.

Published: July 2024

Background: Acute nasopharyngitis is often treated with hypertonic saline that can be combined with additional compounds, such as lysozyme. The aim of this study was to compare efficacy and safety of hypertonic saline solution with or without lysozyme in the treatment of acute nasopharyngitis.
Methods: Non-interventional, prospective, multicentre, observational, parallel study was conducted on adult subjects with symptoms of acute nasopharyngitis. Subjects were divided into hypertonic saline or lysozyme group (receiving slightly hypertonic nasal spray with addition of lysozyme). Time until the patency of both nasal passages was measured after the first application of therapy. The congestion severity was assessed by using a visual analogue scale before the therapy application, after 30 minutes, and after seven days. Adverse reactions were monitored and evaluated.
Results: The total number of included subjects was 252 (60 in the hypertonic saline group and 192 in the lysozyme group). In both groups, a significantly better assessment of the severity of the nasal passages’ obstruction was recorded after 30 minutes and seven days from therapy start (for all compared time intervals p<0.001). The lysozyme group had a significantly lower nasal congestion score compared to hypertonic saline 30 minutes after therapy (p<0.001) and seven days from the therapy start (p=0.001). In the hypertonic saline group, a significantly shorter time was observed to establish the patency of the nasal passages after the first therapy application (p<0.001). All adverse events were mild.
Conclusions: Addition of lysozyme to slightly hypertonic nasal spray brings added value in the pharmacotherapy of acute nasopharyngitis.

Background: Objectives of the study were to assess the age group affected, common presentation, extent of disease of mucormycosis and treatment modalities in post covid patients.
Methods: All covid positive patients or recently recovered from covid with features of mucormycosis endoscopically and radiologically were included in this study. All patients that came in the outpatient department were screened using nasal endoscope and CT scans were performed. Patient’s clinical findings and endoscopic findings were correlated with the scans during the pandemic and decision to operate the cases was taken. It was a team approach by otorhinolaryngologist, ophthalmologist, endocrinologist, intensivist and nephrologist. Patients were followed up to 1 year.
Results: 65 patients that suggested of mucormycosis clinically, endoscopically, and radiologically were studied. It included 50 (76.9%) males and 15 (23.1%) females and histologically after operating, mucor was present in 44 cases (67.6) and 9 (13.8%) were aspergillosis.
Conclusions: Post-COVID mucormycosis was reported after the second COVID wave in India especially after steroid therapies in diabetic patients. Thus, a timely, aggressive, team approach using Modified Denkers or open maxillectomy along with proper intravenous antifungals is the key to survival in such patients.

Published: July 2024

A facelift, also known as a rhytidectomy, is a surgical procedure that improves visible signs of aging in the face and neck, such as sagging caused by relaxation of the skin, deepening of the fold lines between the nose and corner of the mouth, fat that has disappeared or fallen, the development of jowls in the cheeks and jaw, loose skin, and excess fat of the neck that can appear as a double chin or "turkey neck." A number of factors can cause the face to lose its youthful contours, including thinning skin, fat loss, gravity, sun damage, smoking, heredity, and stress. Brow lifts and eyelid surgeries are additional operations that can be used in conjunction with a facelift to revitalize aging eyes. It may be suggested to use fillers or fat transfer to replace the lost fatty volume. Skincare procedures including lasers, dermabrasions, and peels could be recommended to enhance the skin's texture and quality. In the century since it was first introduced, the facelift procedure has seen a significant change. Numerous safe, reliable, and efficient surgical techniques have been developed because to the information gathered by earlier surgeons. There is currently disagreement in the literature regarding the most effective strategy. This indicates that, in the hands of an experienced surgeon, several available surgical options are comparable. Many proponents of the various popular approaches have developed strong cases to back up their positions. The lack of consensus emphasizes how crucial it is to constantly innovating in order to meet patient expectations, enhance longevity, and achieve good surgical outcomes. Similarly, further examination of current methods via carefully planned research is essential for the final creation of a "gold standard." One can observe a similar level of progress in facelift development over the next century, with a focus on the use of new technology and a tendency in that direction. This review article focuses on face lift technique and associated problems experienced medical professional.

Published: July 2024

Introduction: Non-alcoholic fatty liver disease (NAFLD) is a major global health problem, in which liver fat exceeds 5% of the liver weight, without secondary causes of fat accumulation or excessive alcohol consumption. Resistin plays a key role in energy homeostasis, insulin resistance, inflammation, and metabolic disorders. This study aimed to investigate the relationship between resistin (RETN) level and NAFLD.
Methods: In this cross-sectional study, 80 patients with NAFLD and 80 healthy individuals as controls were evaluated. Biochemical variables, liver enzymes, insulin, and resistin were measured. Data were analyzed using SPSS version 16 software.
Results: The variables of cholesterol, insulin, triglyceride, HDL, body mass index, age, and liver enzymes were significantly different between the two groups of patients with NAFLD and healthy individuals (p<0.05). In patients, resistin was associated with triglyceride (r=0.243, p=0.045). No association was found between resistin level and NAFLD grades (p≥0.05).
Conclusion: The results of this study indicate that there is a relationship between resistin and NAFLD. There is no association between resistin level and the degree of NAFLD.

Suppression of an invasive pine by a native shrub following a megafire
Authors: Escobedo Víctor Manuel , Gómez Persy , Molina-Montenegro Marco A. 
Published: July 2024

Abstract

Seedling density of the Chilean wineberry Aristotelia chilensis negatively correlates with the seedlings’ abundance of an invasive pine Pinus radiata, particularly in post-fire areas. This pattern emerged following a megafire in Chile’s Coastal Maulino Forest, a biodiversity hotspot facing increasing fire threats. This pattern, coupled with a high proportion of plots lacking pine seedlings, suggests that A. chilensis may play a role in limiting P. radiata invasion. The negative relationship was strongest in areas with moderate fire severity, likely reflecting differences in shade tolerance. A. chilensis, a light-demanding species with some degree of shade tolerance, can persist in partially shaded environments. In contrast, P. radiata, a more strictly light-demanding species, struggles to establish under significant shade. In high-severity fires, however, we found no significant relationship between these species, likely due to detrimental effects on both species, including potential microbiome dependence for A. chilensis. As A. chilensis shows successful establishment at low fire severity, enhancing its post-fire recruitment, particularly in moderately burned areas, could be a valuable strategy for mitigating P. radiata invasion and restoring fire-affected Mediterranean ecosystems.
Assessing the relationship between river water pollution and the LULC composition of a basin in the Isthmus of Tehuantepec in Oaxaca, Mexico
Authors: Tapia-Silva Felipe-Omar , García-Hernández José 
Published: July 2024

Abstract

Water pollution originating from land use and land cover (LULC) can disrupt river ecosystems, posing a threat to public health, safety, and socioeconomic sustainability. Although the interactions between terrestrial and aquatic systems have been investigated for decades, the scale at which land use practices, whether in the entire basin or separately in parts, significantly impact water quality still needs to be determined. In this research, we used multitemporal data (field measurements, Sentinel 2 images, and elevation data) to investigate how the LULC composition in the catchment area (CA) of each water pollution measurement station located in the river course of the Los Perros Basin affects water pollution indicators (WPIs). We examined whether the CAs form a sequential runoff aggregation system for certain pollutants from the highest to the lowest part of the basin. Our research applied statistical (correlation, time series analysis, and canonical correspondence analysis) and geo-visual analyses to identify relationships at the CA level between satellite-based LULC composition and WPI concentrations. We observed that pollutants such as nitrogen, phosphorus, total coliforms, and water temperature form a sequential runoff aggregation system from the highest to the lowest part of the basin. We concluded that the observed decrease in natural cover and increase in built-up and agricultural cover in the upper CAs of the study basin between the study period (2016 to 2020) are related to elevated WPI values for TSS and FC, which exceeded the allowed limits on all AC and measured dates.

Abstract

Lophopetalum wightianum is a tropical or subtropical forests tree that has an aesthetic value as an ornamental plant, used for timber production and source of essential oils. Because of rapid agricultural and urban development, deforestation, climate change and indiscriminate collection, this important tree species have been included into red list of threatened species. The current study corroborates the earliest and first report on in-vitro micropropagation of L. wightianum aimed to develop a robust and reproducible protocol for mass propagation and conservation of this endangered plant species. Throughout the experiment, about 80% survivality of nodal segments, emergence and proliferation of microshoots and their subsequent multiplication was confirmed on MS medium fortified with BAP 2.0 mg/L and Kinetin 1.0 mg/L. In vitro rooting of L. wightianum shows recalcitrance and 40% rooting proficiency was achieved on 1/4 strength MS medium supplemented with low conc. of auxins (3.0 mg/L IBA and 0.5 mg/L IAA) for a prolong period of culture (03 months) where reduced concentration (2%) of sucrose showed a remarkable impact on root initiation. On the contrary, ex-vitro rooting trial yielded 55% of rooting competency with 72 hours of transient dipping of shoots on MS media supplemented with 50 mg/L IBA. Remarkably, 93% of in-vitro rooted plants survived during the acclimatization phase at open field condition. Plants survived from ex-vitro trial showed vivid growth and development after six months at field condition. The current findings provide greater insights for future research and conservation strategy of L. wightianum.
