A Case of Waldenström’s Macroglobulinemia Complained of Anorexia
No full textIt has been reported that an 82-year-old man had complained of “anorexia with wasting away (weight loss of 35 pounds) over the past six months”. The cause was unknown, and his appetite dropped to only liquid milk and soy milk every day. On further examination, his CA-199 (a tumor marker) was in the normal range, but the serum IgM level was found to be 4 times higher than normal, and lymphoplasmacytic cells in his bone marrow were 2 times higher than normal. His myeloid differentiation factor (MYD88) was detected to be positive in gene mutations, confirming a diagnosis of “Waldenström’s macroglobulinemia” (WM) complicated with “Bing-Neel syndrome” (BNS); as a result, the anorexia was attributed to it, and the symptomatic treatment with Traditional Chinese Medicine (TCM) was proposed to improve his condition

Snowfall Shift and Precipitation Variability over Sikkim Himalaya Attributed to Elevation-Dependent Warming
No full textSikkim Himalaya hosts critical water resources such as glacial, rain, and snow-fed springs and lakes. Climate change is adversely affecting these resources in various ways, and elevation-dependent warming is prominent among them. This study is a discussion of the elevation-dependent warming (EDW), snowfall shift, and precipitation variability over Sikkim Himalaya using a high-resolution ERA5-land dataset. Furthermore, the findings show that the Sikkim Himalaya region is experiencing a warming trend from south to north. The majority of the Sikkim Himalayan region shows a declining trend in snowfall. A positive advancement in snowfall trend (at a rate of 1 mm per decade) has been noticed above 4500 meters. The S/P ratio indicates a shift in snowfall patterns, moving from lower elevations to much higher regions. This suggests that snowfall has also transitioned from Lachung and Lachen (3600 m) to higher elevated areas. Moreover, the seasonal shifting of snowfall in the recent decade is seen from January-March (JFM) to February-April (FMA). Subsequently, the preceding 21 years are being marked by a significant spatiotemporal change in temperature, precipitation, and snowfall. The potent negative correlation coefficient between temperature and snowfall (–0.9), temperature and S/P ratio (–0.5) suggested the changing nature of snowfall from solid to liquid, which further resulted in increased lower elevation precipitation. The entire Sikkim region is transitioning from a cold-dry to a warm-wet weather pattern. In the climate change scenario, a drop in the S/P ratio with altitude will continue to explain the rise in temperature over mountainous regions
Understanding the Challenges of Implementing Green Roofs in Multi-Family Apartment Buildings: A Case Study in Khulna
No full textGreen roofs are widely recognized for their multifaceted benefits to the environment, economy, and society, constituting the fundamental pillars of sustainability. These roofs contribute to the enhancement of bio-physical diversity, provision of food resources, regulation of temperature and rainfall-runoff patterns, creation of wildlife habitats, and augmentation of aesthetic and recreational value. While Bangladesh, with its favourable climatic conditions and rapid urbanization, possesses immense potential for harnessing the advantages of green roofs, their adoption remains limited in both research and practical applications within the country. Addressing this research gap, the present study aims to investigate the barriers impeding the implementation of green roofs in existing or new multi-family apartment buildings, focusing specifically on the city of Khulna. Through a combination of case studies and a comprehensive questionnaire survey administered to diverse stakeholders including apartment dwellers/owners, architects, developers, and government officials with varying levels of expertise, this research sheds light on the obstacles hindering Green Roof Implementation (GRI). The identified barriers encompass a lack of governmental policies, inadequate technological advancements, inaccurate estimation of economic benefits, and individual resistance. In light of the perspectives of various GRI stakeholders, strategic proposals encompassing policy, technical, economic, and social dimensions are presented to surmount these barriers. The outcomes of this study contribute to the dissemination of knowledge pertaining to the impediments to GRI implementation, thereby inspiring further research endeavours and enabling decision-makers to formulate robust policies facilitating the widespread adoption of green roofs
Examining the Effectiveness of Virtual Training under the Kirkpatrick Model: A Post-COVID Study
No full textTeaching and training through online tools were used by most Higher Education Institute (HEIs) worldwide during COVID-19 to cater to the needs of students who stay far away from educational institutions. After the pandemic, the virtual model of education and training became a trend. The students and teachers are also more used to this trend which is giving more opportunities to both learners and instructors. One of the notable benefits of virtual teaching and learning platform is that it provides a flexible environment to gain knowledge, skills, and attitude simultaneously along with formal off-line education. From the earlier studies it is found that the majority of studies have focused on traditional, offline training methods and only a few studies have focused on virtual training. Therefore, the present study examined the effectiveness of virtual training using the Kirkpatrick model. For this purpose, a research instrument based on the Kirkpatrick model was constructed and distributed among the UG and PG students in Mangalore City. A total of 143 responses were collected, of which 132 were completed responses and all of them were considered for analysis. Descriptive statistics and one sample t-test are employed to analyse and interpret the data. The findings revealed that virtual training is more effective compared to traditional and offline training methods. Henceforth, the training and education provided through virtual platforms made significant contributions to the employability of youngsters
Problems and opportunities for biometeorological assessment of conditions cold season
No full textThe article is devoted to a discussion of the possibilities of biometeorological assessment of the severity of weather conditions during the cold season. The relevance of the study is ensured not only by the fact that residents of a number of states, whose total number is more than 27 million people, live in these extreme climatic conditions, but also by the need to improve biometeorological approaches to assessing the impact of these conditions on the body and health of the population. This study examined biometeorological characteristics that illustrate a measure of cold stress. These include the Siple wind-chill index; Bodman winter severity index; Arnoldi weather hardness coefficient; Mountain wind chill index; weather hardness coefficient according to I.M. Osokin. The results of a comparison of winter severity assessments based on the values of the calculated Siple and Bodman indices made it possible to establish that the Bodman index is more acceptable when assessing mildly severe winters. The most adequate for assessing the "severity" of the cold period against the background of a decrease in air temperature and an increase in wind speed is the Siple index. The need to provide the countries of the world with high-quality hydrometeorological and biometeorological forecast information is justified and relevant. In this regard, these studies are very promising
Matrix-Material Fabrication Technique and Thermogravimetric Analysis of Banana Fiber Reinforced Polypropylene Composites
No full textFrom the environmental consideration, it would be very interesting to use natural fibers such as banana, jute or coir as reinforcement materials instead of artificial fibers or any kind of synthetic materials. Natural fibers have many advantages over synthetic ones. Polypropylene banana fiber composites (PPBC) are prepared using untreated and alkalitreated banana fibers at 10-25% by weight of the fiber loading. The thermal properties of polypropylene natural fiber composites are very important for technological uses. Thermogravimetric measurements show that the incorporation of banana fiber into PP enhances the thermal stability of composites containing treated fibers, in comparison with untreated fibers. A composite of biodegradable polypropylene (PP) reinforced with short banana natural fibers was prepared by melt blending followed by a hot press molding system. The thermal properties of matrix materials were studied using thermogravimetric analyzers TGA units. It is observed that the introduction of short banana fibers slightly improved the thermo oxidative stability of PP-banana composites. Physical and chemical changes occurred through dehydration, phase transition, molecular orientation, crystallinity disruption, oxidation and decomposition, and incorporation of several functional groups. Systematic investigations of the thermal behavior of polymers in gas, vacuum or inert atmosphere give the knowledge of how change takes place in polymers. To understand such changes thermogravimetric analysis (TGA) and thermal analysis (TG) were performed. It is observed reinforcement of short banana fiber leads to little improvement in the thermooxidative stability of PPBC. Due to the enhancement of thermo-mechanical properties, such composites may be used as building materials namely roof materials, selling materials and many other engineering applications
The Problems and Measures for Small Tourism Town Development in China: A Case Study of Wan Town
No full textWith the rapid development of tourism and urbanization in China, small tourism towns gradually grow toward prosperity. This paper takes Wan Town as an example to analyze the problem and countermeasures concerning the development of small tourism towns in China. There are a series of issues in the process of development of Wan Town, which includes uncoordinated architectural style, inaccurate market positioning, repeated cultural themes, and vulnerable linkage of the industrial chain. Based on the factor analysis, these development issues were classified into three categories: confusing architectural style, repetitive cultural theme, and weak linkage of industrial chain. To achieve the goal of sustainable development of small tourism towns, some countermeasures must be taken which include promoting the development of small tourism towns with the new rural revitalization, strengthening services improvement in small tourism towns, gathering industrial elements related to the tourism industry, and increasing tourism cultural connotation
Case Study of Coastal Fog Events in Senegal Using LIDAR Ceilometer
No full textThis study aims to examine the atmospheric conditions characterising fog phenomena on the Senegalese coast focusing on two specific instances that occurred on April 3 and April 30, 2023. These events were detected by the LIDAR Ceilometer installed at LPAOSF/ESP/UCAD and confirmed on the METARs of the meteorological stations at Dakar and Diass airports. The LIDAR's backscatter signal showed that the fog of April 3 started around midnight with a vertical extension at 100 m altitude and dissipated around 10 a.m. The April 30 event characterized by a good vertical extension from the surface up to 300 m above sea level, was triggered just after 2 a.m. and lasted around 3 hours. The results showed that a decrease in temperature, accompanied by an increase in humidity and light wind, is favorable for the triggering and persistence of fog. Sea Level Pressure (SLP) anomaly fields show two distinct configurations. The April 3 event was characterized by a zonal dipole of SLP anomalies between the Sahara and the northern Senegalese coast, while the April 30 event was characterized by a meridional dipole between the Sahara and the Gulf of Guinea area as far as the equatorial Atlantic. A weakening of the pressure around the study area was observed in both cases, allowing moisture advection to favor the onset of fog. The hovmoller diagrams of relative humidity and wind show that a good vertical extension of humidity associated with a westerly wind in the lower layers plays an important role in the formation and persistence of fog. The presence of dry air associated with a weak easterly wind in the middle layers could explain the low vertical extension of the fog on April 3. A strong wind in the lower layers would be responsible for the premature dissipation of the April 30 fog
