Towards sustainable charcoal production: Designing an economical brick kiln with enhanced emission control technology

In this research, a brick kiln integrated with pollutant emission control technology was designed and applied in order to produce charcoal from Eucalyptus Globules wood. The batch operation carbonization of wood biomass was undertaken in a 1.25 m3 volume brick kiln. A wet-packed scrubber was designed and constructed by filling gravels in a depth of 40 cm with aggregate sizes of 48–60 mm, 27–33 mm and 16–20 mm from the bottom to the top respectively aiming to treat emission from the charcoal-producing unit. The characteristics of the charcoal produced were determined to be composed of 9% moisture content, 1.5% ash content, 38% charcoal yield and a heating value of 27.53 MJ/kg. On the other hand, the wet scrubber integrated into a brick kiln was found to remove Hydrocarbons, CO2 and CO by 97.8%, 98.5% and 99% respectively, which makes it efficient and practical way of controlling the gasses released during producing of charcoal.

Biodiversity and Structural Analysis of Woody Plant Species of Home Gardens in Basona Worana District, North Shoa Zone of Central Ethiopia.

The purpose of this study was to investigate the biodiversity and structure of woody plants of HGs in the Basona Worana district (BWD). For this, six kebeles and 138 HGs from three agroecologies of BWD were selected using various sampling techniques. The plot size used per HG was 400 m2. Diversity and important value indices (IVIs) were computed. For their structural analysis, the diameter at breast height (DBH) and height were also measured for trees and shrubs fulfilling the standards (diameters at breast height (DBH) ≥2.5 cm and height >2 m). Thus, a total of 42 woody species belonging to 37 genera and 26 families were identified. Fabaceae was the most abundant family, followed by Euphorbiaceae. Trees were the dominant habit. The richness in Kola HGs (33) was higher than Dega (14) and Woinadega (19) HGs, with an overall mean richness of 4.14 per HG of BWD. The Shannon, Simpson, and evenness indices for HGs in the district were 1.05, 0.55, and 0.75, respectively, showing their moderate diversity with even distribution. The Sorenson's similarity of HGs between Dega and Woinadega, Kola and Dega, and Kola and Woinadega were 40%, 28%, and 32%, respectively. The multiple site similarities of woody species among three ecological zones (36%) were still <50%, showing no similarity. The overall DBH and height classes' patterns of the woody species individuals abruptly decreased towards their highest classes. Similar DBH and height classes' patterns of woody species individuals were also observed in Kola and Woinadega agroecologies, indicating their selective tree cutting. The mean values of DBH, height, basal, and crown areas of the woody species in the district were ∼14 cm, ∼6 m, ∼29 m2·ha-1, and 5 m2, respectively. Based on IVI, most of the HGs were dominated by Eucalyptus globules (93.35), followed by Eucalyptus camaldulensis (45.04), Rhamnus prinoides (22.4), and Cupressus lusitanica (22.33). Hence, actions should be taken to promote the diversity and managing of HGs' woody species of BWD.

Energy implications of the mycosphaerella sp. in eucalyptus globules stands

In the last decade, the emergence of leaf disease caused by the fungus Mycosphaerella sp. is jeopardizing the development of some species of the genus Eucalyptus at its juvenile life stage. The development of forest species for energy purposes, namely to generate biomass in shorter periods, must take into account this circumstance at the time of measuring the energy density generated by these species. This paper defines a method which relates the measure of the severity of the disease with the energy lost per Ha. First, it has been characterized from the energy point of view, thus, it has quantified the calorific value of the biomass of Eucalyptus globulus decomposing it in their respective fractions at certain moisture. Then, depending on the degree of severity of the disease, it has been estimated the amount of dry biomass per tree at the age of 27 months and crossing it with the calorific values it has been determined the energy loss per unit of area according to the overall damage index. Finally, a brief economic analysis considering the consequences of this disease in a stand of Eucalyptus globulus for energy production, has been performed.

An Ethnobotanical Survey of Indigenous Knowledge on Medicinal Plants Used by Communities to Treat Various Diseases around Ensaro District, North Shewa Zone of Amhara Regional State, Ethiopia

The study was conducted to investigate and document medicinal plants and associated knowledge on the utilization, management, preparation, and way of administration of the medicinal plant resources in Ensaro district, north Shewa zone, Ethiopia. A total of 100 informants were sampled from four study sites, and questionnaire surveys, semistructured interviews, ranking, and transect walk techniques were employed for data collection in midland, lowland, and highland agroecology and natural forests, riverine forests, and farmlands. Vast sources of the traditional healing knowledge of plant species conveyed from one generation to the next by word of mouth were from a family. A total of 101 medicinal plant species were identified from the study site, which belong to 95 genera and 49 families. These medicinal plants are used to treat about 35 types of human ailments. Families Fabaceae and Poaceae were represented by the highest number of medicinal plant species, followed by the Asteraceae, Lamiaceae, and Euphorbiaceae species. Out of the total medicinal plants’ species, 46.53% were herbs and 33.66% were shrubs. Most of them have medicinal properties in their leaf, root, seed, bark, stem, latex, sap seed, and fruits. Medicine from these plant parts is prepared in fresh, dried, and both fresh and dried states. The highest informant consensus was documented for the plant Ocimum lamiifolium used by 75% of informants for its medicinal value in treating fibril illness. Cucumis ficifolius and Eucalyptus globules are used by 41% and 39% of informants ranking second and third, respectively, for their medicinal value. This study revealed that indigenous knowledge of traditional medicine is still popular among local communities in the study area. The conservation strategy practiced by local people is not enough to tackle the erosion of plant species from their habitats. Thus, the conservation of these plants and the associated knowledge base is very essential.

The efficient activity of plant essential oils for inhibiting Botrytis cinerea and Penicillium expansum: Mechanistic insights into antifungal activity

Botrytis cinerea and Penicillium expansum produce deterioration in fruit quality, causing losses to the food industry. Thus, plant essential oils (EOs) have been proposed as a sustainable alternative for minimizing the application of synthetic fungicides due to their broad-spectrum antifungal properties. This study investigated the efficacy of five EOs in suppressing the growth of B. cinerea and P. expansum and their potential antifungal mechanisms. EOs of Mentha × piperita L., Origanum vulgare L., Thymus vulgaris L., Eucalyptus globules Labill., and Lavandula angustifolia Mill., were screened for both fungi. The results showed that the EO of T. vulgaris and O. vulgare were the most efficient in inhibiting the growth of B. cinerea and P. expansum. The concentration increase of all EO tested increased fungi growth inhibition. Exposure of fungi to EOs of T. vulgaris and O. vulgare increased the pH and the release of constituents absorbing 260 nm and soluble proteins, reflecting membrane permeability alterations. Fluorescence microscopic examination revealed that tested EOs produce structural alteration in cell wall component deposition, decreasing the hypha width. Moreover, propidium iodide and Calcein-AM stains evidenced the loss of membrane integrity and reduced cell viability of fungi treated with EOs. Fungi treated with EOs decreased the mitochondria activity and the respiratory process. Therefore, these EOs are effective antifungal agents against B. cinerea and P. expansum, which is attributed to changes in the cell wall structure, the breakdown of the cell membrane, and the alteration of the mitochondrial activity.

In vitro Study: Determining the Antibacterial Activity of Different Concentrations of Essential Oil against Streptococcus sanguinis Isolated from supragingival Plaque

Several mouth diseases are common health issues, including dental caries and periodontal disease. In the absence of prevention, these conditions result in periodontal pockets. It has been proven that periodontal diseases are associated with supra-gingival plaque bacteria, including Streptococcus sanguinis. To avoid antibiotic side effects and bacteria becoming increasingly resistant, an alternative to antibacterial agents must be developed to ensure no side effects or increased resistance. As a consequence, natural herbs and Ayurveda drugs have become increasingly important. This research aims to investigate the antibacterial activity of Eucalyptus Globules essential oil against Streptococcus sanguinis bacteria. An evaluation of the anti-microbial effects of different concentrations of Eucalyptus Globules oil on Streptococcus sanguinis bacteria was conducted using a well-plate approach was also utilized to compare the effects of Eucalyptus Globules oil on bacterial growth in comparison to 0.2% chlorhexidine mouthwash. It was found that Eucalyptus Globules essential oil was highly antibacterial against Streptococcus sanguinis as the concentration of extract increased, with a highly significant difference (P ≤ 0.01) between all concentrations and chlorhexidine. Thus, this antibacterial activity of Eucalyptus Globules essential oil against Streptococcus sanguinis suggests that it could be used as a natural antibacterial component in treating oral infections.

Eucalyptol induces osteoblast differentiation through ERK phosphorylation in vitro and in vivo.

Eucalyptol (EU) is monoterpene oxide that is the main component of the essential oil extracted from aromatic plants such as Eucalyptus globules. EU has therapeutic effects such as antibacterial, anti-inflammatory and antioxidant in chronic diseases including inflammation disorder, respiratory disease, and diabetic disease. However, the effects of EU on osteoblast differentiation and bone diseases such as osteoporosis have not been studied. The present study investigated the effects of EU on osteoblast differentiation and bone formation. EU induces mRNA and protein expression of osteogenic genes in osteoblast cell line MC3T3-E1 and primary calvarial osteoblasts. EU also promoted alkaline phosphatase (ALP) activity and mineralization. Here, the osteoblast differentiation effect of EU is completely reversed by ERK inhibitor. These results demonstrate that osteoblast differentiation effect of EU is mediated by ERK phosphorylation. The efficacy of EU on bone formation was investigated using surgical bone loss-induced animal models. EU dose-dependently promoted bone regeneration in zebrafish caudal fin rays. In the case of ovariectomized mice, EU increased ERK phosphorylation and ameliorated bone loss of femurs. These results indicate that EU ameliorates bone loss by promoting osteoblast differentiation through ERK phosphorylation. We suggest that EU, plant-derived monoterpenoid, may be useful for preventing bone loss. KEY MESSAGES: Eucalyptol (EU) increases osteoblast differentiation in pre-osteoblasts. EU up-regulates the osteogenic genes expression via ERK phosphorylation. EU promotes bone regeneration in partially amputated zebrafish fin rays. Oral administration of EU improves ovariectomy-induced bone loss and increases ERK phosphorylation.

Effect of eucalyptol on matrix metalloproteinase-9 and its tissue inhibitor in hypertensive rats.

Effects of eucalyptol, a key component of eucalyptus globules, on matrix metalloproteinase-9 (MMP-9) and its tissue inhibitor (TIMP-1), compared with lisinopril, were investigated in a model of hypertension induced by chronic intraperitoneal (IP) injection of low dose nicotine in rats. The hypertensive rats were randomly allocated to 4 groups (n=8): Positive control (PC, untreated), eucalyptol-treated group (1.0 mg/kg, IP), lisinopril-treated group (10 mg/kg, IP), and eucalyptol+lisinopril-treated group. Systolic blood pressure and plasma levels of MMP-9 and TIMP-1 were measured. All treatments decreased the elevated blood pressure and plasma levels of MMP-9 and TIMP-1 most significantly with the combination group which showed non-significant differences from the normal control group. Lisinopril reduced plasma levels of MMP-9 and TIMP-1 more significantly than eucalyptol. In conclusion, eucalyptol significantly decreased the increased plasma levels of MMP-9 and TIMP-1 in nicotine-induced hypertension in rats. Moreover, its combination with lisinopril exerted more significant effects compared to each drug alone. This makes this combination particularly useful in hypertension and related cardiovascular disorders where suppression of MMP-9 and TIMP-1 activities decreases the related complications and improves the overall morbidity and mortality. To our knowledge, the current data are novel, and may open the way for development of a co-delivery system of both drugs which could be beneficial in treatment of hypertension in chronic smokers.

Experimental Investigation on Flexural Strength Enhancement of Eucalyptus based Bamboo Composite Deck Board

The study investigates the effect of the relative height position of specimen and bamboo layering in the preparation of composite flexural material from Eucalyptus Globules and Oxytenanthera abyssinica bamboo for the purpose of floor deck construction. Furthermore, flexural improvement was tested by laminating bamboo beneath eucalyptus, which has a high tensile stress resistance, using unsaturated polyester resin as the bonding medium. The experiment was carried out on specimens taken from the bottom and middle parts of the sample with regard to total height. The results of the tests revealed that single and double-layer bamboo laminated eucalyptus in the bottom part showed an increase in flexural strength by 26.5% and 33.06%, respectively, and that the bottom portion strength had improved due to the addition of bamboo. However, in the case of the middle part specimen, the addition of a bamboo lamination on the Eucalyptus resulted in a (20.31%) increase for single and (−41.79%) decrease for double layer in strength compared to the non-laminated middle part Eucalyptus.

Effect of Land Use Change on Soil Physico-Chemical Properties under Different Land Use System in Arsi Zone, Oromia Region, Ethiopia

The establishment of artificial plantation using Eucalyptus globules in Ethiopia is becoming economically important for improving the livelihoods of small holder farmers. The species are adapted to different soil depths with varied responses to soil physical and chemical properties that have an implication on the proper management of environmentally sensitive areas. However, the sources of variations of soil physical and chemical properties have not been well investigated and documented for most vertisol in Ethiopia. This study was designed to investigate soil physical and chemical properties variations under different land use systems of cropland, grazing land and trees covered area with Eucalyptus globulus plantation at Gusha Temela Kebele, Arsi Zone and Oromia, Ethiopia. A total of 48 composite soil samples with 4 replicates * 3 treatments * 2 sampling plots * 2 at soil depths of 0–10 and 10–20cm were used for laboratory analysis. Some of the soil physical and chemical properties were analyzed and interpreted including soil texture, bulk density), soil moisture content, pH, available phosphorus (available P), soil organic carbon, total nitrogen and carbon to nitrogen ratio (C/N ratio). The results showed that, except in a few cases, all considered soil properties showed significant differences with land use types and soil depths. Soil Bulk density (r=0.0002), soil moisture content (r&lt;0.0001), soil pH (r&lt;0.0001), available phosphorus (0.0002) and soil organic carbon (r&lt;0.0001) were significantly varied with land use types. Textural fractions of sand, silt and clay showed no significant difference with land use types and soil depths. Although not significant, the clay content was slightly higher under grazing land. On the other hand, soil parameters including bulk density, soil moisture content, pH, soil organic carbon and total nitrogen were higher under grazing land than in the rest land use types and significantly varied with respect to soil depths; greater in the lower soil depth except for soil organic carbon and total nitrogen which were higher in the upper soil depth. The textural fraction of clay across all land use types was higher in the lower depth than in the upper surface layer which could be due to the translocation of this fine particle from the upper soil layer to the lower one. Findings of the present study indicated that land use change has more effect on soil chemical than physical parameters that grazing land is more fertile than other land use types. It implies that management practices significantly influence soil chemical properties variations especially the soil organic carbon concentrations for better employment of land management practices through implementation of climate smart agriculture.

Ethnobotanical survey of medicinal plants of bejaia localities from algeria to prevent and treat coronavirus (COVID-19) infection shortened title: phytomedicine to manage COVID-19 pandemic

The propagation of the COVID-19 pandemic in Algeria has pushed the population searching alternative therapies as preventives and treatment selections. The use of medicinal plants is a promising alternative solution to strengthen immunity and chase COVID-19. The aim of this study was to carry out an ethnobotanical survey in the Bejaia department (Algeria) to identify the plants used during the current pandemic. The study was conducted from February to May 2021. The interviews were conducted with 400 informants in order to assemble socio-demographic and floristic features of the respondents and used plants. The data analysis was performed by means of Relative Frequency of Citation (RFC), Family Importance Value (FIV), and Plant Part Value (PPV). 23 medicinal plants belonging to 12 families were adopted by the population of the Bejaia localities to prevent and treat COVID-19 infection. Aloysia citriodora Palau (RFC = 0.248), Mentha spicata L. (RFC = 0.145), Citrus limon (L.) Osbeck (RFC = 0.135), Thymus vulgaris L. (RFC = 0.118), Zingiber officinalis Roscoe (RFC = 0.09), Artemisia herba-alba Asso (RFC = 0.065), and Eucalyptus globules labill (RFC = 0.063) were the most cited species. The leaves of these plants which are used (65%) in the form of infusion (43.6%) are administered orally (95.03%) to treat and relieve certain symptoms of COVID-19. The current survey is the only one in the Bejaia department regarding the exploitation of medicinal herbs in the COVID-19 pandemic. These plants can be used as a platform to manage COVID-19.

A new perspective of aroma face mask on COVID-19 pandemic

In times of the COVID-19 pandemic, wearing face masks is strongly recommended as a public health measure to stop the spread of the Sars Coronavirus. However, there are still people who ignore using this effective protective tool due to the lack of comfortable face masks on the market. Therefore, in the current study, we assessed commercially available face masks namely N95 masks, surgical masks, and cloth masks in order to find out their weakness. In addition, the identification needs of people from a face mask were collected by an online questionnaire. According to the information obtained; we achieved key factors required to design a new type of face mask using the Computer-Aided Design (CAD) and the final design was printed. Moreover, the long-term use of herbs in Iranian Traditional Medicine persuaded us to add a humidifier containing aromatic plants essential oils such as Eucalyptus globules Labill. and Rosa damascene Mill. with scientifically proven health benefits such as pain reliever, relaxing properties and antimicrobial activities. We are expected that these aromas would be an effective way to eliminate the problems of individuals suffering from air pollutants, respiratory disorders, and COVID which leads to encouraging more people to use face masks during pandemics or air pollution.

Therapeutic Efficacy of Garlic (Allium sativum), Turmeric (Curcuma longa) and Eucalyptus (Eucalyptus globules) Extracts in the Treatment of Bovine Endometritis

Background: Endometritis is one of the major causes of subfertility in bovines. The present study was conducted to evaluate the therapeutic efficacy of ethanolic extracts of garlic, turmeric and eucalyptus in the treatment of bovine endometritic as an alternative to antibiotics. Methods: Forty crossbred cows affected with endometritis were equally divided into 4 groups. Group I (control) cows were treated intrauterinely (i.u) with streptopenicillin 2.5 g + 30 ml normal saline for 3 days and group II, III and IV cows were treated (i.u) with 30-40 ml of ethanolic extract of garlic, turmeric and eucalyptus for 3 consecutive days. The animals were inseminated artificially on subsequent estrus after the treatment. Result: Bacterial count in uterine flushing declined significantly after treatment in all the four groups. The percentage of reduction in bacterial count was higher in garlic treated cows than in control and other treatment groups. A significant increase in percentage of PMNs was found after treatment in all the groups. The overall conception rate was 40% in control group, 50% in group II and 30% in group III and IV. It was concluded that ethanolic extract of garlic for the treatment of endometritis resulted in better conception rate and significantly higher percentage reduction of bacterial load than other treatment and control groups.
