Clinico-spirometrical correlation of newly detected COPD patients with known tobacco smoking exposure or biomass smoke exposure presenting to a teaching institution in Vadodara, Gujarat

ABSTRACT Introduction: Chronic respiratory symptoms (dyspnoea, coughing, sputum production) associated with abnormalities of the airways (bronchitis, bronchiolitis) and/or alveoli (emphysema) that result in persistent, frequently progressive airflow obstruction are the hallmarks of COPD, a diverse lung illness. The current investigation aimed to establish a clinical profile of patients with recently diagnosed COPD who present to a healthcare facility in Vadodara. Materials and Methods: The Department of Respiratory Medicine conducted an observational cross-section study on individuals with recently discovered COPD. The study comprised records of 50 participants, from September 2022 to January 2024. Along with the spirometry results, pertinent clinical data were gathered. Results: The study’s patient population presented with an average age of 61.52 years. The fact that every patient in the research was over 40 years old suggests that COPD is becoming more common in people over 40. There was a male majority among the 50 patients, with 40 (80%) male and 10 (20%) female. Most common age group was smokers accounted for 80% of the total cases, suggesting that their incidence of COPD is greater. Average FEV1 at presentation was 41 L/min for 50 patients. Among 50 patients, 6% falls under mild, 28% under moderate, 42% under severe, and 24% under very severe according to GOLD grading and severity of airflow obstruction. Conclusion: Despite the fact that tobacco smoke is thought to be the main cause of COPD. Indoor and outdoor air pollution are major issues in many nations, including India. One of the main risk factors for COPD is smoke from activities such as burning wood or biomass fuels in addition to work exposure. The ageing of the global population and ongoing exposure to COPD risk factors are expected to contribute to a rise in the prevalence and burden of COPD in the ensuing decades. The fact that most newly diagnosed patients in this research were older and more symptomatic and that most identified individuals had moderate to severe COPD, indicates the importance of spirometry programs in primary care for the early detection of COPD. Our findings suggest that a new campaign requiring patients to undergo spirometry and routine follow-up may be able to identify a sizable proportion of patients with undiagnosed COPD and perhaps improve their quality of life.

Selected aspects of the impact of energy wood harvesting on the forest environment

Abstract Global demand for energy, including renewable energy, continues to rise. As a result, the proportion of woody biomass used for energy purposes is also increasing. The article focuses on a literature review of selected natural consequences of forest biomass utilisation for the forest environment. The impacts of harvesting forest biomass for energy purposes consider three harvesting systems: conventional harvesting (CH), whole-tree harvesting (WTH) and whole-tree harvesting with stump removal (WTH + S). The results of the literature review show that harvesting for energy affects the forest environment, including soil productivity, forest water and biodiversity. The impacts are mostly negative and largely depend on the harvesting system. This literature review shows that the more intensive the timber harvesting system (WTH, WTH + S) is, the greater the impact on the natural environment. Of all systems, conventional timber harvesting (CH) has the best impact on the natural environment.

Assessment of timber and fuel wood harvesting practices and distribution pattern in CFUGs of Khotang District, Nepal

Proper harvesting of forest products is necessary for sustainable forest management, playing a pivotal role in minimizing damage and waste while ensuring the sustainability of forest resources. Sustainable community forest management greatly depends on the harvesting and fair distribution of various forest products (FP). The study's goals were to ascertain the methods, instruments, and strategies utilized in the harvesting process, forest products distribution pattern, and the common issues surrounding the distribution and harvesting of FP in Imo and Ashoje Community Forest (CF) located in Khotang District, Nepal. Operational Plan (OP), focus groups, key informant interviews, household surveys, and minute books were used for data collection. 25% of all households were chosen at random from each of the two CF. The study revealed that traditional methods and tools such as sickles, bill hooks, axes, and saws, were commonly used in the past; however, there has been a shift towards modern tools in recent years. Deviations were observed in forest products harvesting and distribution from that of OP in practice. Fuel wood were equally distributed, timbers were allocated based on priority and circular basis ensuring user satisfaction. The slope was the major constraint for harvesting, as most of the marked trees were not cut because of difficulty in extraction. To improve sustainable forest management, it is recommended that advanced tools and training be provided to users, with regular monitoring by forest officials to ensure adherence to best practices. These measures will help enhance user responsibility and ensure sustainable harvesting operations.

ETNOBOTÁNICA DE ÁRBOLES ÚTILES EN SISTEMAS AGROFORESTALES DE LA SIERRA DE ZONGOLICA, VERACRUZ, MÉXICO

<p><strong>Background:</strong> traditional ecological knowledge generated by different human groups is manifested in the various forms of appropriation of nature, particularly by intervening in the growth processes of plant species to take advantage of them and maintain them in the long term. The sierra of Zongolica is one of the most important indigenous areas in Mexico, where the use of forest resources is part of their livelihoods. There is evidence that in this region trees are used as raw material for furniture, construction, food, charcoal and firewood. <strong>Objective:</strong> to learn about the diversity, main uses and importance of multipurpose trees within agroforestry systems in the Sierra de Zongolica, Veracruz. <strong>Methodology:</strong> 74 semi-structured interviews and direct observations were conducted on the land of the interviewees and analyzed using a mixed approach, through a social network analysis to determine the main uses of the trees. <strong>Results:</strong> A total of 79 species of useful trees were recorded, belonging to 41 taxonomic families, of which the Fabaceae family was the most abundant with 4 species recorded. Sixty-two genera were found, of which the most abundant was the <em>Quercus </em>genus. Ninety-five percent of the informants were men around 50 years of age, demonstrating that they are the ones in charge of the productive activities and that they are the ones with the knowledge about the use and management of the trees. The household is made up of an average of 4 people, which makes it difficult to work in the fields due to the scarcity of family labor, which could jeopardize productive activities because people outside the family must be employed to use and manage the trees. <strong>Implications:</strong> since wood energy, construction, medicinal and food uses are of vital importance in this work, sustainable management practices should be implemented, such as selective harvesting, replanting and local tree management, so that firewood collection and trade benefit both rural areas and the environment. <strong>Conclusions:</strong> about 79 useful tree species were identified in Zongolica's agroforestry systems, demonstrating the diversity of natural resources in the region. These species are fundamental to the local economy and environmental conservation, providing firewood, food, medicines and construction materials for local communities. It is crucial to value and protect these forest resources to ensure their continuity and contribute to the sustainability of agroforestry systems in Zongolica.</p>

Assessment of Fuel Wood Consumption and Its Effect on Forest Depletion in Dry Deciduous Forest of Haliyal Taluk, Uttar Kannada District, India

Forest plays a significant role in extending wood and non-wood resources around the world, Forests provide ecosystem services, such as timber, food, fuel, fodder, non-wood products and shelter, which are essential for human well-being. However the increasing demand and pressure on forest resources majorly like fuel wood lead to degradation of forests. Hence it is important to assess the fuel wood consumption pattern and its impact on the forest for sustainable management of resources. In the present study, Haliyal taluk was selected, the area which is under rapid urbanization, surrounded by dry deciduous forest and the people living in that area depend on forest for fuel wood consumption. The study examined fuel wood collection among different farmer categories: large, medium, small, and landless. Results from the semi structured questioner survey revealed that medium farmers collected the most fuel wood. The total fuel wood consumption in Haliyal taluk was 5232.2 tonnes, with an average household consumption of 2.60 quintals of fuel wood per year. Major preferred tree species for fuel wood were Xylia xylocarpa, Terminalia tomentosa and Lagerstroemia lanceolata, which are valued for their high energy content, favourable burning characteristics and availability. For estimation of forest degradation Randomized Block Design was used and the study classified the forest vegetation into four crown density classes: Very Dense Forest (T1), Moderately Dense Forest (T2), Open Forest (T3), and Scrub (T4). Data was collected from 20 plots (20 x 20 m each) across these classes to measure forest depletion. The results showed that statistically significant differences in degradation levels, with the highest depletion (31.56 m³/ha) in very dense forests followed by moderate depletion (6.75 m³/ha) in moderately dense forests and the lowest (2.4 m³/ha) in scrub forests. This pattern reflects greater anthropogenic pressures and higher fuel wood availability in more dense forest types.

The effects of microwave and microwave + infrared drying treatments of Pinus brutia and Picea orientalis on water absorption and physical properties

The goal of this study was to find a way to shorten wood drying time by using microwave and combined infrared + microwave drying methods and to analyze color and gloss changes. Wood samples prepared in three groups with dimensions of 20×20×30 mm were used in moisture tests and 75×5×150 mm were used in color change and gloss measurements, obtained from Red pine (Pinus brutia) and Eastern spruce (Picea orientalis) woods. The samples were oven dried, dried by microwave, or dried by infrared + microwave drying method. The wood samples all reached the target moisture. Their weight and volume were calculated in accordance with the principles of TS ISO 13061-1. Color change values were determined before and after drying with a portable color reader (Konica Minolta CR-10) device, and gloss measurements were taken with the Gardner brand gloss meter. By microwave drying for 15 min, 4% moisture content was reached in the wood samples, so both time and energy were saved. The moisture content values decreased compared to the whole drying methods. Most color change was observed in the drying methods using infrared for both red pine and eastern spruce.

Automated LPG Monitoring and Rebooking System using IoT- A Review

LPG (Liquified Petroleum Gas) has become an essential requirement in daily life, as many people rely on it for cooking, fueling vehicles, and more LPG offers a portable, clean, and efficient alternative to traditional fossil fuels, making it especially valuable for rural and urban areas in India. By replacing wood, coal, and other traditional fuels, LPG enhances health, air quality, and overall comfort. To simplify the LPG rebooking process for domestic and commercial use, various applications have been developed. This study presents a brief overview of existing research on LPG monitoring systems and proposes a method for automatic rebooking by monitoring LPG consumption in real-time and triggering an automatic refill request when the gas level reaches a predefined threshold. The system also provides users with notifications and updates about the status of the LPG, further enhancing convenience and reliability.

Experimental Assessment of Energy Potentials from Tea Wastes as a Source of Energy: A Case of Itona Tea Factory in Tanzania

Tea processing is an energy-intensive process. However, high agricultural productivity and subsequently the growth of the green revolution have been made possible only by a large amount of energy inputs, especially those from fossil fuels, wood fuels, and electricity. With recent price rise and scarcity of these fuels there has been a trend towards use of alternative energy sources such as waste (agricultural waste) to energy that could solve both energy and environment issues. Moreover, these energy resources have not been able to provide an economically viable solution for agricultural applications so long as they seem to contain amount of energy which can be source of energy to be used in various factories in rural areas through gasification process. A gasifier is normally fuel specific system and it is tailored around a fuel rather than the other way round. Hence, this paper presents an experimental assessment of energy potentials from tea wastes available at Itonaa Tea Factory for tea drying processes as important data for agricultural wastes. The experimental measurement of energy potential from tea wastes was done using bomb calorimeter, muffle furnace and energy balances to determine calorific value moisture content and energy potentials of tea waste respectively. The findings indicate that the combined energy potential of factory and garden tea waste was found to be 2.78x10<sup>8</sup>kWh, and corresponding electrical energy was estimated to be 2.78x10<sup>7</sup>kWh which is enough for tea drying process in tea manufacturing plant. The total energy used in the production of tea was discovered to be equal 3.5 - 7.5 kWh/kg of made tea. Thus, total energy consumption (4.5 kWh/kg of made tea) for processing of 9.6 x 10<sup>6</sup> kg of tea from 4.5 x 10<sup>3</sup> hectares of tea plantation in Mufindi for the period of 2021-2022 was 4.32x10<sup>7</sup> kWh. Thus, with the proper utilization of energy conversion technology of tea waste, part of the energy requirement in processing of tea could be met reducing environmental challenges associated with both wood fuel burning and tea waste disposal.

Thermal Characteristics of Malaysian Khaya Senegalensis Wood Fuel Pellets: Densification-Induced Changes at Different Feedstock Moisture Levels

This study investigates the thermal behaviour of Malaysian Khaya senegalensis wood energy pellets, examining the effects of densification at different feedstock moisture levels. Densified wood pellets are promising renewable energy sources, but the impact of densification on thermal characteristics, considering various moisture contents, is underexplored. The main objective is to quantify the thermal characteristics, which involved proximate analysis such as energy pellets’ ash content, fixed carbon, volatile matter, and calorific value. In this research, Malaysian Khaya senegalensis wood was converted into pellets through a densification process, spanning from of 4-20% feedstock moisture levels. The manufactured pellets were then subjected to various tests to characterize the thermal properties. Results reveal compelling insights on the relationships between densification, moisture content, and thermal properties. Densification significantly influenced thermal attributes, with effects tied to initial moisture content. Varying moisture levels led to distinct thermal responses, reflecting interactions between densification-induced changes in moisture and thermal responses. In this study, the best moisture content for ash content was found to be 16%, with 3.24% ash content, 16% moisture content with volatile matter of 85.24%, fixed carbon of 12% from 20% moisture content, and 16% moisture content with calorific value of 19.65 MJ/kg. These findings aid Khaya senegalensis wood pellet densification optimization for improved thermal performance. Understanding densification's impact on thermal behaviour under varying moisture conditions enhances pellet efficiency as sustainable energy sources. This research contributes to biomass pellet knowledge for renewable energy applications, advancing efficient and eco-friendly energy solutions.

Household Fuelwood Consumption and Its Implication for Carbon Dioxide Emission

This review paper aims to gather informative data on the impact of climate extremes on the physical environment, public health, and the livelihoods of people in Ethiopia. The primary sources of data for this review were peer-reviewed journal articles obtained from electronic databases such as PubMed, Central, Scopus, and Web of Science. Globally, the vast majority of households in developing countries depend on wood energy for their daily energy needs. Such consumption trends are expected to remain a common feature of traditional wood energy production and consumption, at least in the short- to medium-terms. This situation increases the demand for firewood and charcoal from the forest. The process of harvesting standing trees for charcoal and fire wood leads to forest degradation. Although woody biomass has the function of energy consumption, and as a source of income for rural villagers and urban poor dwellers practicing agriculture, wood energy generally has low priority in national policies of developing countries. However, unsustainable management and negative environmental consequences in humid and dry forests is derived from the use of fuel wood energy. Still now there is an unsystematic assessment of the economic contribution and environmental consequences of wood energy use, so its significance and consequences have been minimized. This deforestation and forest degradation contributes 1–2.4 Gt CO2e of greenhouse gases, which is 2–7% of global anthropogenic emissions, with global greenhouse gas emissions mostly CO2.

Assessment and selection of a micro-hybrid renewable energy system for sustainable energy generation in rural areas of Zambia

This research focuses on the implementation of micro-hybrid renewable energy systems (MHRES) in rural Zambia, where a large part of the population lacks adequate electrical infrastructure. Using a multi-criterion decision-making approach (MCDM), specifically the Technique for Preference Order by Similarity to an Ideal Solution (TOPSIS) with an entropy-weighted method, this research aims to identify an optimal MHRES solution to replace dependence on wood and fossil fuels. Analysis is carried out in 14 scenarios, taking into account technical, economic, social, and environmental criteria. The results show that a biogas-solar photovoltaic integrated with Energy System Power Safe Storage Battery Systems 190 (SBS 190) is the most visible option, demonstrating a relative proximity of 0.98556. In contrast, a diesel generator-solar PV system is the least favorable, with a relative proximity of 0.02576. Validation of the results through a convergent distance assessment (CODAS), an evaluation based on the distance from the average solution (EDAS), and the weighted aggregate sum of the product assessment (WASPAS) confirm its robustness. The proposed MHRES solution is designed to meet the energy needs of rural communities using local biomass and solar resources, free of obstacles by high buildings and structures. This research highlights the potential of MHRES to meet energy needs and promote sustainable development in developing countries, providing valuable insights for policymakers and energy stakeholders.

Fibre morphological characteristics, chemical composition and fuel properties of paulownia COTEVISA-2 wood

AbstractThe aim of this study was to determine the elemental composition and the fibre morphological characteristics, chemical and fuel properties of wood from paulownia COTEVISA-2 clone growing on a plantation near Granada, Spain. The research was carried out on five boards representing five 5-year-old trees, taken from a height of approximately 2–3 m. Morphologically, COTEVISA-2 wood has fibres with mean length 0.923 mm, diameter 0.029 mm, lumen width 0.026 mm, and cell wall thickness 0.0015 mm. The slenderness ratio ranged between 19.27 and 64.31, the Runkel ratio between 0.060 and 0.4259, the rigidity index between 2.83 and 19.94, Mühsteph’s index between 0.1099 and 0.5082, and the flexibility coefficient between 0.701 and 0.943. Significant differences between trees were found for the values of morphological characteristics of fibres and the derived indices, apart from the solids index. Mean values of chemical properties obtained from two parallel determinations for each sample showed that the wood contains on average 48.15% cellulose, 27.48% lignin, 7.38% pentosans and substances soluble in cold water (2.38%), hot water (3.87%), ethanol (5.51%) and 1% NaOH (19.64%). The elemental composition of paulownia COTEVISA-2 wood is as follows: C – 49.06%, H – 6.19%, N – 0.43%, S – 0.021%, Cl – 0.05%. The wood contained 0.4% ash. The heat of combustion of paulownia COTEVISA-2 wood is 18.58 MJ/kg, and the calorific value is 17.18 MJ/kg. The results suggest that paulownia COTEVISA-2 is a promising wood for energy and paper production.

Food offerings and firewood: Integrated archaeobotanical analyses of seed/fruit and wood charcoal remains from a Hellenistic-Roman Cemetery on Tinos Island, Cyclades

Archaeobotanical studies have already been widely and successfully used in Greece for the Neolithic to Iron Age periods, yet they were mostly omitted in Classical archaeology. This was justified by the existence of ancient texts, that provide information on plant use in Antiquity. However, not every aspect of life and plant use is described in ancient texts, and additionally, research of past vegetation relies solely on the studies of plant remains. A rescue excavation of a Hellenistic-Roman cemetery with pyres and graves on Tinos Island in the Cyclades provided not only charred seeds/fruits and leaves, but also large amounts of charcoal. The material enabled the study of food offerings / grave goods of plant origin, as well as the choice and availability of fuel wood for cremations. The olive (Olea europaea) seems to have been an important food crop on the island, as it was found in high quantities, accompanied by barley (Hordeum vulgare) and other cereals (Cerealia), as well as cereal products (ACO = amorphous charred objects), figs (Ficus carica) and grapes (Vitis vinifera). Fuel wood for the cremations was mainly based on evergreen oak (Quercus sect. Ilex) and olive wood (Olea europaea), the latter probably deriving from prunings produced in olive groves. Other macroremains, such as a leaf of kermes oak (Quercus coccifera), myrtle charcoal (Myrtus communis) and heather leaves (Erica manipuliflora) point to fuel harvest in Phrygana shrubland, which is the main vegetation form found on the island today.

Eco-Efficiency of Pellet Production from Dedicated Poplar Plantations

Biomass, due to its neutrality in terms of greenhouse gas emissions into the atmosphere during its life cycle, is considered an interesting renewable source for energy production as an alternative to the use of more polluting fossil fuels. Among the different wood fuels, pellets are convenient for use in dedicated stoves, and pellet heating systems have a high energy efficiency. The aim of this work was to estimate the economic and global warming potential (GWP100a) generated along the thermal energy supply chain of wood pellets, starting from the production of raw biomass from dedicated poplar cultivations and ending with the use of pellets in stoves by the end-user to produce thermal energy and ash. The Eco-Efficiency Indicator (EEI) was used to link the economic and environmental performance for eight proposed scenarios, obtained by combining different levels of mechanisation for poplar harvesting and wood biomass management before arrival at the pellet plant. For the thermal energy produced by the poplar wood pellet, the GWP100a ranged from 1.5 × 10−2 to 2.1 × 10−2 kg CO2−eq MJ−1 for three-year-old plantations and from 1.9 × 10−2 to 2.4 × 10−2 kg CO2−eq MJ−1, for six-year-old plantations. In terms of eco-efficiency of the baseline scenario (EEIb), the most favourable scenarios remain those linked to the use of biomass from three-year-old poplar plantations, with EEIb values ranging from 0.31 to 0.60 € kgCO2−eq−1, compared to from 0.29 to 0.36 € kgCO2−eq−1 for pellets obtained from biomass produced from six-year-old poplar plantations. In terms of the Global Eco-Efficiency Indicator (EEIg), which also takes into account the positive effect on the reduction of greenhouse gases due to the storage of carbon in the soil by the plantations and the reduction of emissions from avoided fossil fuels, the most favourable scenarios remain those linked to the use of biomass from three-year-old poplar plantations, with EEIg values that vary in the range of 0.60 ÷ 1.04 € kgCO2−eq−1, compared to 0.55 ÷ 0.62 € kg CO2−eq−1 for thermal energy obtained using biomass from six-year-old poplar plantations.

Characterization of hygrothermal, gas pressure and stress characteristics for poplar wood during unilateral surface densification

Unilateral surface compression in wood presents notable benefits, including reduced wood volume loss and energy consumption, rendering a highly promising and extensive utilization. However, shortcomings in compressed wood arise due to unclear gas pressure, temperature, and moisture content distribution within the wood during hot pressing. In this paper, the temperature and pressure distribution were analyzed utilizing an optical fiber temperature and pressure measurement system within the wood during hot pressing. Moreover, the moisture content, stress and strain in each layer at the end of hot pressing were discussed extensively. The results showed that the wood surface layer (SL) and subsurface layer (SSL) maximum temperature values were similar even with different layer thicknesses. Under sealing conditions, SL and SSL temperatures were generally 6 ℃ to 7 ℃ higher compared to unsealing conditions. The gas pressure maximum value exhibited an opposite order, gradually transferring to the core layer (CL) and declining as the processing time extended. During compression treatment, moisture migrated from the hot end to the cold within the wood. The moisture content displayed significant differences between the middle and end parts of the wood under unsealed conditions, with the disparity becoming more pronounced further away from the hot end. The transition region of the compressed wood served as a stress concentration area, experiencing the highest levels of stress. The dense region followed with the second highest stress levels, while the un-densified region exhibited the least amount of stress. Under the same process parameters, the thickness had little influence on the distribution of dense layers.

Postharvest evaluations of soil erosion, ground cover, and best management practice implementation on integrated biomass and conventional clearcut harvest sites

As demand for wood energy rises, it’s vital to understand the environmental impact of various harvest types, considering different best management practices (BMPs) and site conditions, for sustainable forest management. This study provides a comparative analysis of postharvest site characteristics between biomass and conventional harvest sites located in the Coastal Plain region of the southeastern US. A total of 30 recently harvest sites (15 each for biomass and conventional) were selected from the Coastal regions of Alabama, Georgia, and Florida. Erosion rates were estimated using the USLE-Forest method and ground cover was assessed as a percentage of the area covered by bare soil, litter, light slash, heavy slash, and piles. BMP implementation (%) was based on state-specific BMP surveys. The findings show that stream management zones (SMZs) and harvest areas were less prone to soil erosion, while forest roads, skid trails, and stream crossings were more prone to erosion, regardless of the harvest type. Conventional harvest sites had an overall weighted average erosion rate of 0.35 Mg/ha/year, with an average BMP implementation of 92.70 %, while biomass harvest sites had an overall weighted average erosion rate of 0.22 Mg/ha/year, with an average BMP implementation rate of 97.91 %. Average erosion rate (Mg/ha/year) from the harvest area (biomass=0.11, conventional=0.06) and SMZs (biomass=0.05, conventional=0.02) were not significantly different (p>0.05). Conversely, average erosion rate from roads (biomass=4.17, conventional=6.44), skid trails (biomass=2.15, conventional=3.73), decks (biomass=0.39, conventional=0.72), and stream crossings (biomass=1.53, conventional=5.31) were significantly higher in conventional harvest sites (p<0.05). BMP implementation rates for roads (biomass=98.09 %, conventional=93.71 %), stream crossings (biomass=95 %, conventional=71 %), and timber harvest (biomass=96.44 %, conventional=93.33 %) were significantly higher in biomass harvest sites, while waste management BMP (biomass=89.91 %, conventional=100 %) was significantly higher in conventional harvest sites. Regarding ground cover, conventional harvest sites had significantly larger areas covered by light slash, heavy slash, and piles than biomass harvest sites, while biomass harvest sites had significantly larger areas covered by green growth. Our research shows a significant negative correlation between overall BMP implementation and erosion rates (r=-0.67, p=0.0002), as well as site size (r=-0.38 p=0.0400), indicating that larger sites tend to have lower BMP implementation and increased erosion risk. In conclusion, biomass harvest sites in our study did not yield higher erosion rates in comparison to conventional harvest sites, provided that the current BMP recommendations were implemented properly and in adequate amounts. This study emphasizes the importance of site-specific management strategies to mitigate erosion in all harvest sites, irrespective of harvest type used.
