Authors: Surumi B. , Jayakumaran Nair A. , Rajalakshmi R. , Prabha Kumari C.
Published: November 2022

Obesity is a global health problem manifested due to various adipose tissue dysfunctions. Insights on adipogenesis and adipocyte development may unravel new strategies for the treatment of obesity and related metabolic diseases. Adipogenesis is controlled by many transcription factors and epigenetic regulators; PPARγ and C/EBPα are master adipogenic transcription factors. A clear understanding of transcriptional regulation mechanism of adipogenesis seems crucial. Expanding facts and knowledge demonstrated that long non-coding RNAs (lncRNAs), a category of non-protein coding RNAs of size greater than 200 nucleotides are identified as potential regulators in obesity-related biological processes through diverse mechanisms. Nuclear enriched abundant transcript 1 (NEAT1), a nuclear lncRNA interacts with nuclear domains that controls sequestration of paraspeckle proteins. NEAT 1 has evolved as a vital regulator involved in different cellular processes, developmental processes and physiological responses along with disease development and progression. In this mini review, the potential role and the basic mechanisms of lncRNA NEAT1 in adipogenesis are discussed. Clear understanding of the recent advances of lncRNAs is emphasized that will recommend the future application of lncRNAs in the treatment of obesity.

Published: November 2022

Mining operations produce large amounts of waste effluent that contain compounds of varying toxicity that leach into aquatic bodies. We investigated the effects of water samples from a gold mining area on oxidative stress biomarkers in Helisoma duryi. Water was collected from four sites in the mining area: site 1, Mtshabezi water from a river 3 km from the mine and sites 2, 3 and 4 (underground water, waste effluent, process water) at the mine. The water samples were analysed for cyanide and heavy metals. Snails in groups of 30 were exposed to one liter volumes of water from sites 1- 4 and the control for up to 14 days. Cyanide levels in the 0.1 – 0.5 mg/L range were observed in water sampled from sites 1- 4. Cadmium, chromium, copper, lead and zinc were observed in all water samples from the mining area. Superoxide dismutase and catalase activities were enhanced in snails exposed to samples from the mining area. Increased concentrations of malondialdehyde, which indicates oxidative stress were observed in snails exposed to water from sites 1-4, suggesting that mining operations directly or indirectly release pollutants that include oxidative stressors which affect the wellbeing of aquatic organisms.

The metal complexes containing Cu(II), Co(II) and Ni(II) metal ions were synthesised in the molar ratio of 1:2 [M:L] and azo Schiff base ligand as a primary ligand. The synthesized metal complexes were confirmed by the different analytical and spectroscopic techniques like UV-Visible, FT-IR, NMR, LC-MS and P-XRD techniques. The binding interaction of synthesized metal chelates with CT-DNA has been investigated by absorption spectra, viscosity measurements and thermal denaturation techniques. The mode of binding of the metal complexes with calf-thymus DNA has been explored. The metal complexes [Cu(II), Co(II) and Ni(II)] intercalated between the base pairs of the CT-DNA tightly with intrinsic binding constant (Kb) in Tris - HCl buffer containing 50 mMNaCl buffer. The DNA cleavage activities of the complexes were clearly assayed by using pUC-18 DNA which was monitored by the gel electrophoresis method. The antibacterial activity was carried out by a well-diffusion method against gram-positive bacteria S. aureus and gram-negative bacteria Shigella. Amylase inhibitory activity of pooled fractions was carried out according to the standard method with minor modification (antidiabetic activity). The in silico molecular docking was achieved with the DNA binding receptor PDB ID: 1E3Y taken from RCSB Protein Data Bank (www.rcsb.org/pdb). The receptor structre was prepared before use in docking study using protein preparation module of HEX 8.2 modelling package.

Authors: Shakila S. , Venkatraman B.R.
Published: November 2022

The microwave-assisted green fabrication of tin dioxide (SnO2), iron (Fe)-doped tin dioxide (SFO), nickel (Ni)-doped tin dioxide (SNO) and cobalt (Co)-doped tin dioxide (SCO) nanoparticles (NPs) was illustrated employing Psidium guajava leaf extract (PGLE). The fabricated NPs were characterized by X-ray powder diffraction (XRD), Field emission scanning electron microscopy (FESEM), X-ray photoelectron spectroscopy (XPS), Energy-dispersive X-ray spectroscopy (EDAX) and Photoluminescence (PL) spectroscopy. XRD patterns of fabricated SnO2, SFO, SNO and SCO NPs show a rutile structure. FESEM study suggests that the fabricated NPs are spherical structure. The XPS scan validated the oxidation states of O (1s), Sn (3d), Fe (2p), Ni (2p) and Co (2p). In PL investigations, transition metals (Fe, Ni and Co)-doped SnO2 NPs enhance PL intensity compared with pure SnO2 NPs. PL spectroscopy shows that transition metals (Fe, Ni and Co)-doped SnO2 NPs enhance the PL intensity compared with pure SnO2 NPs. Employing Williamson-Hall (W-H) equations and W-H plotting method, the physical parameters of strain and stress are computed.

Authors: Iqbal Kashifa , Dutta Venkatesh
Published: November 2022

Rivers are facing seasonal as well as long-term changes in their hydro-ecological regime in response to multiple stressors that have affected water quality as well as flow volumes. Ramganga is an important tributary of the Ganga River that provides freshwater to the people of Uttar Pradesh and Uttarakhand. In recent years, industrial discharges, agricultural and municipal wastes and wastewater releases have severely polluted the river throughout its stretch. The contamination index (CI) values at Moradabad in the pre-monsoon, monsoon and post-monsoon seasons were 0.78, 0.86, 0.76-not contaminated, at Bareilly 1.68, 1.65, 1.22-slightly contaminated, at Dabri 2.32, 2.34, 1.76-slightly contaminated while the pollution index (PI) values at Moradabad were 1.76, 2.23, 1.43-slightly contaminated, at Bareilly 4.29, 4.49, 3.95-severely contaminated and at Dabri 13.06, 12.21, 9.49- severely contaminated. The pollutants responsible for high pollution are NH3+, PO4-3, SO4-2, NO2-+NO3- which primarily come from agricultural run-off as the farmers use phosphate, ammonium and sulphate fertilizers and pesticides. The land use type along the banks of the Ramganga in Bareilly and Dabri is primarily dominated by agricultural lands. Hence, the increased CI and PI values at Bareilly and Dabri clearly indicate high agricultural pollution.

Published: November 2022

The increasing availability of drug-resistant Plasmodium falciparum infections is putting a strain on the accessibility of potent, safe and cost-effective anti-malarial treatments, necessitating the development of new anti-malarial drug. Malaria deaths were estimated to be around 409000 in 2019. The present study sets to identify novel antimalarial compounds and the virtual screening study reveals that the designed compounds bind more effectively to Plasmodium falciparum chloroquine resistance transporter (PfCRT) and Plasmodium falciparum Multidrug Resistant1 (PfMDR1) than the known inhibitors. Marvin JS was used to design the chemical structure of the molecules and the molecular docking of 75 designed molecules with PfCRT and PfMDR1 was performed to study the interaction between the small molecule and the proteins. The top docked scoring compounds with the respective proteins were subjected to molecular dynamic simulation to study their interaction stability. The ADME/T (absorption, distribution, metabolism and excretion/toxicity) properties of those molecules were also studied and the majority of the properties was found to be within acceptable ranges. After experimental validation to confirm the findings, the screened molecules could be used as potential anti-malarial drugs.

Published: November 2022

Controlled release drug carriers have gained significant interest in recent years due to their potential to produce greater therapeutic success. To address this need, the study presents the fabrication of sodium alginate/poly(vinylpyrrolidone-co-vinyl acetate) microbeads intercalated with montmorillonite (MMT) clay and silver nanoparticles for the controlled release of levofloxacin by a simple ionotropic gelation technique. The prepared beads were characterized using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (X-RD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) etc. The antibacterial activities of the synthesized microbeads were tested against Escherichia coli and Bacillus cereus by the agar disc diffusion method. The developed microbeads could significantly inhibit bacterial development. In vitro release studies and swelling studies were carried out at pH 7.4 simulated intestinal fluid and pH 1.2 simulated gastric fluid at 25 oC and 37 oC. The MMT-containing microbeads showed higher encapsulation efficiency and controlled drug release than other formulations. The results obtained from the swelling and in vitro release studies revealed that pH had influenced the drug release of developed microbeads and that they are suitable for intestinal drug delivery. The in vitro release kinetics was assessed by fitting the release data into the Korsmeyer- Peppas equation and finding that the release mechanism follows the Fickian diffusion process.

Authors: Kaur Gursharan , Dhanya M.S.
Published: November 2022

The present study explores the possibility of using waste cotton fabrics (WCF) as a potential feedstock for the production of glucose by dilute acid pre-treatment and evaluation of the effect of temperature on glucose recovery. The WCF at 1% (w/v) solid loading was pre-treated with five different concentrations of dilute sulfuric acid from 1 to 5% (v/v) at 100°C for 30 and 60 minutes. The glucose production from WCF increased with the increase in temperature, time and concentrations of dilute sulphuric acid pre-treatment. The rate of increase in cellulose hydrolysis of WCF with the temperature over time was higher for pre-treatment with concentrations of 1-3% dilute sulfuric acid than 4 and 5%. The temperature of 100°C improved recovery rate of glucose from 60 min hydrolysis of WCF with 1,2,3,4 and 5% dilute acid concentrations by 2.93 folds, 2.21 folds, 1.63 folds, 1.91 folds and 1.73 folds respectively. The structural changes of WCF by dilute acid pre-treatments were confirmed by Scanning Electron Microscope (SEM) analysis.

Published: November 2022

The current study is focused on the conversion of 2- chlorosalicylaldehyde into its oxime which was then converted into 5-chloro-2-hydroxy-benzonitrile 1, a key starting material for the present synthetic work. The nitrile 1 on reaction with chloroacetone/phenacyl bromide/4-chlorophenacyl bromide in anhydrous acetone and potassium carbonate gave 2-acyl-3- amino-5-chlorobenzofuran (2a-c). Acetylation of compounds 2a-c furnishes 2-acyl-3acetamido-5- chlorobenzofuran (3a-c). Compounds 3a-c on further treatment with hydrazine hydrate undergo ring closure producing 3-amino-8- chloro-2, 4-dimethyl-3, 4-dihydro [1] benzofuran [3, 2- d] pyrimidin-4-ol (4a-c). The synthesised compounds were characterised by spectral and analytical data and screened for antibacterial and antifungal activity.
Tuning the competition between photoisomerization and photothermy in biomimetic cyclocurcumin analogues

Published: November 2022

We report the synthesis and photophysical characterization of biomimetic D-A-D’ cyclocurcumin derivatives, which can potentially be used in light activated chemotherapy. Particularly we highlight that both the donor (D) and acceptor (A) groups significantly influence the photophysical response of the chromophore inducing strong bathochromic shift with D/A strength increase and notable fluorescence quantum yield enhancement with donor strength increase. More important, the nature of the acceptor group (oxo or malonitrile) dramatically modifies the outcome in non-radiative deactivation channels. Indeed, while compounds functionalized with an oxo-moiety undergo ethylenic E→Z photoisomerization, the one bearing a malonitrile group leads exclusively to other non-adiabatic internal conversion channels which much favor photothermal conversion as no isomerization of the ethylenic double bond being observed. The tuning of the photophysical properties and the alteration of isomerization vs. photothermal conversion is rationalized through the analysis of the potential energy surfaces along the most relevant degrees of freedom and shows a competitive pathway over malonitrile rotation. Our results offer novel perspective in oxygen-independent light activated chemotherapy and in the control of photochemical processes in biomimetic chromophores.

The electrochemical production of hydrogen arises as one of the most important strategies to mitigate the problems caused by the pollution and the strong dependence on fossil fuel-derived sources of energy. Thus, improvements in the overall electrolysis process can contribute with this task. One of the problems that has been confronted for decades is the sluggishness of the electro-oxidation of water by preparing a myriad of materials with limited success. Therefore, instead of keeping on looking for materials to be applied for this reaction, one possibility is to change the water for another cheap substance, easier to be oxidized. In this context, biomass-derived resources, like several alcohols and polyols, emerge as suitable candidates to be oxidized in the anodes of electrolyzers. This way, it is possible to concomitantly obtain high purity hydrogen at the cathode and value-added biomass derivatives at the anode. Herein, to avoid/decrease the use of noble metals, we prepare Ag/C catalyst and modify the Ag surface by different quantities of Pt. The catalyst containing only 0.5% of Pt reached half the electro-oxidation peak current of Pt/C. Besides, considering the current normalized by Pt mass, this material is around 80 times more active than Pt/C. Apart from the electrochemical results, we irradiated our materials with white light and observed an increased activity for the electro-oxidation of glycerol, showing the presence of a plasmonic effect. FTIR in situ and HPLC online showed that all the catalysts produced glycerate, lactate, glycolate and formate and that the selectivity do not change with the irradiation of light. The most important difference between the materials was that while Pt/C produce carbonate, this specie was not detected for Pt-Ag/C. Finally, the materials were also tested for the electro-oxidation of ethanol, showing that they are promising for the electro-oxidation of several alcohols/polyols. Therefore, this study paves the way for future optimization of Ag/C catalyst modified on its surface with different more active materials that must be afterward tested in real devices like, for instance, anion exchange membrane electrolyzers.
Comprehensive COSMO-RS Exploration of Highly CO2 Selective Hydrogen-bonding Binary Absorbents even under Humid Conditions
Authors: Watabe Shiori , Kuroki Nahoko , Mori Hirotoshi
Published: November 2022

Improving the carbon capture efficiency with reducing the cost is mandatory for popularizing carbon capture, utilization, and storage (CCUS). Considering the objectives of green chemistry and engineering, here we show a theoretical exploration of the CO2-absorbing capacity of a set of 1,527,030 deep eutectic solvents (DESs). Comprehensive statistical thermodynamic calculations followed the previous experiments that DESs, including choline chloride, would have better CO2-absorbing capacity than those composed of non-ionic hydrogen bonding species in the case that choline chloride is used as a hydrogen-bonding acceptor. Quantitative evaluation of hydrogen-bonding interaction also indicated that the CO2-absorbing capacity would increase further when choline chloride is used as a hydrogen- bonding donor.

Fe-N-C catalysts, the most promising platinum group metal (PGM)-free oxygen-reduction catalysts, often simultaneously contain pyrrolic N- (S1) and pyridinic N (S2) -coordinated FeN4 sites. These two types of active sites show significantly different intrinsic activity and stability. S1 sites are more active but less stable compared to S2 sites. Designing a Fe-N-C catalyst, which exclusively contains active S1 sites with enhanced intrinsic stability, is highly desirable to break the activity-stability trade-off. Herein, we report a Fe-N-C model catalyst that solely comprises S1 sites prepared by adding H2 in the pyrolysis atmosphere (i.e., 10% H2/Ar). A membrane electrode assembly (MEA) with the Fe-N-C cathode demonstrated compelling activity and generated a current density of 50.8 mA cm−2 at 0.9 ViR-free (H2-O2) and 211 mA cm−2 at 0.8 V (H2-air), which have significantly exceeded the U.S. DOE 2025 targets. The highly active Fe-N-C catalyst also demonstrated improved stability during life tests and accelerated stability tests (ASTs). The knowledge obtained from experimental and theoretical results elucidates that the FeN4 site formation process can be controlled by thermal activation atmospheres, which is essential to breaking activity-stability trade-off and design viable Fe-N-C catalysts with adequate activity and stability for proton exchange membrane fuel cells.

Needles in the ritual of cattle-breeding magic of the Volyn inhabitants
Authors: Pozhodzhuk Dmytro
Published: November 2022

Purpose: based on field ethnographic materials collected by the author, to describe the cattle-breeding rites associated with the use of needles (“strain milk on needles”, “cook a strainer with needles”) on the historical and ethnographic territory of Volyn, and to find out their regional peculiarity.

Research methodology is based on the comparative historical and descriptive methods, principles of historicism and objectivity. The main material for this study was collected by the author during the field historical and ethnographic expeditions on the territory of Volyn using the pre-compiled thematic program questionnaire.

Scientific novelty. For the first time, one of the important fragments of the spiritual culture of Volyn inhabitants has been substantially described in detail. The rite of “straining milk on needles” was considered in some professional scientific studies that deal with the traditional folk culture of the Slavs, so far in passing. Moreover, even sporadic mentions of it usually do not apply to Volyn as a historical and ethnographic region of Ukraine. The new archival sources put into scientific circulation will promote further study of demonological, calendar-household and cattle-breeding features of the folk culture of Ukrainians.

Conclusions. A needle is the main object in the cattle-breeding magic of Volyn inhabitants, it helps not only to recognize a witch but to get rid of her harmful influence on cattle and milk. The rite of “straining milk on needles” (to cook a strainer with needles) was practiced on the territory of historical ethnographic Volyn everywhere. However, it was marked by a variety of options, which are more a consequence of the personification of respondents than a reflection of local specificity. The action with needles was rarely dedicated to one of the holidays of the folklore calendar; it was mostly an occasional phenomenon. The needle was in the past and is still the main object (sporadically, a sickle and a knife were also used), owing to which the Ukrainians of historical and ethnographic Volyn not only recognized the witch, but also made her vulnerable. The rite with needles, fire and a strainer gave the possibility to get rid of the harmful influence of the witch under some favourable circumstances. This process was quite painful for her, people believed that after the rite of staining milk on needles the witch should be burned and stabbed inside. Moreover, the witch (as an extremely unwanted guest) had every chance to feel the wrath of the man of the house - the owner of the injured cow and to suffer physically.

Countries all over the world are experiencing the devastating havoc of climate change. Drastic efforts directed at integrating climate change education into the school curriculum in South African Secondary schools have been unsuccessful due to a lack of training support for teachers teaching Climate Change Education in secondary schools. The purpose of this paper was to explore the role of teacher capacitation programs in assisting Geography teacher to integrate climate change education in their lessons. Shulman’s Model of Pedagogical Reasoning served as theoretical lenses for the study. Five secondary schools out of twenty which participated in the five days’ training program conducted by one higher education institution were purposefully selected. Data for the study was generated through one-on-one semi-structured interviews conducted with five participating Geography teachers in the selected schools according to the geographical location and close proximity to the training provider. It emerged from the data that teachers were lacking content and pedagogical knowledge on Climate Change Education and this capacitation program assisted in bridging that gap. The study concludes that training programs were according to selected Geography teachers’ views responsible for the improved pedagogical practices in the classroom. It is therefore recommended that teacher professional development programs on Climate Change Education for Geography teachers be organized on a continuous basis.

La potencia de lo grotesco: carnaval, muerte y renovación en Com o coração saindo pela boca, de Jonathas de Andrade
Authors: Cardella Sebastián Nicolás
Published: November 2022

En la 59ª Bienal de Venecia, el artista brasileño Jonathas de Andrade exhibió la imagen de un cuerpo despedazado partiendo de toda una serie de expresiones típicas del lenguaje familiar y popular brasileño que, justamente, aluden a diferentes partes corporales. Por tanto, en este trabajo nos proponemos analizar esta exposición, considerando que la misma reproduce una concepción grotesco-carnavalesca del mundo y del cuerpo.  De esta manera, el artículo demuestra el modo en que la obra de De Andrade puede ser abordada desde esta perspectiva, así como la forma en que la misma porta una indudable potencia político-disruptiva en tanto promueve, por su propia lógica grotesco-carnavalesca, la degradación y relativización de las normas, códigos, identidades y formas de corporalidad hegemónicas, abriendo con ello la posibilidad para su reforma, cambio y renovación.

This study was conducted to investigate effects of different levels of ammonium nitrate (33% N) dose (0, 50 and 100 g m-2) on morphological and quality traits of 3 different commonly cultivated turfgrass species (Lolium perenne ‘TOPGUN’, Festuca rubra ‘SERGEİ’ and Poa pratensis ‘AVALANCHE’) which are widely preferred in grass mixtures prepared for green areas in Çanakkale (Turkey). Fertilization treatments had positive effects on morphological parameters, except for germination power and germination rate parameters. In terms of landscape related aesthetic quality and growth percentage, 50 g m-2 and fertilization was found to be more suitable for Lolium perenne, while 100 g m-2 fertilization provided better performance for Festuca rubra. The 50 and 100 g m-2 fertilization rates yielded similar results for Poa pratensis in terms of general grass quality. It was observed that 50 g m-2 ammonium nitrate had a positive effect on root area and volume compared to other applications. In this application (50 g m-2 ammonium nitrate), the positive features of the root (high root area and volume) are the features that can prevent the grass plant from breaking off from the soil.

The financial system can be considered as a system that ensures the formation of investment and savings decisions and efficiently transfers savings to appropriate areas in the economy. Financial development, in its most general definition,
can be defined as the qualitative and quantitative improvement of financial intermediation services and a positive process in system efficiency. The development of the financial system in an economy creates positive effects on
economic factors. Due to this importance, especially in recent years, the literature on the subject has made great progress and studies have intensively performed modern methods such as time series and panel econometrics. In this
context, postgraduate theses that can be scanned in the YÖK database written on financial development and financial deepening have been tried to be examined with the bibliometric analysis. Bibliometric methods are developing day
by day thanks to the growing body of knowledge in the research field. By the help of these methods, trends in the research field can be determined. In this regard, 75 postgraduate theses in the database on 9/12/2021 were evaluated
within the scope of the analysis. Although the subject in general has started to attract attention since the mid-2000s, the bumber of theses follow a fluctuating course over the years. It can be concluded that the theses mostly
consist of master theses and mainly with econometric models.

Bu çalışmanın genel amacı; işletmelerde çalışanlarında var olabilecek duygusal ahrazlık (aleksitimi) ile, örgütsel dedikodu ilişkisi ve etkileşiminin olup olmadığını tespit etmeye yöneliktir. Yöntem: Bu çalışmada duygusal ahrazlık
(aleksitimi) ile örgütsel dedikodu değişkenleri arasında ilişki ve etkileşim olup olmadığı tespit edilmeye çalışılmıştır. Duygusal ahrazlık (aleksitimi) ve alt boyutları ile örgütsel dedikodu değişkenleri ve alt boyutları arasındaki
ilişki ve etkileşim ayrı ayrı ele alınmıştır. Araştırma çerçevesinde kurgulanan modelde ilişkisel ve etkileşimsel model şeklinde desenlenmiştir. Araştırma kapsamında incelenen örneklem grubu, İzmir Kemalpaşa Organize Sanayi Bölgesinde
faaliyet gösteren işletmelerde üst ve alt pozisyonlarda çalışan toplam 411 kişiden oluşturmaktadır. Araştırma çerçevesinde veri elde edebilmek için Bagby vd. (1994) tarafından geliştirilen, Türkçeye ise Güleç vd (2009) tarafından
çevrilen ve 20 soru ile üç ayrı alt boyuttan oluşan Toronto alaksitimi ölçeği ile birlikte Han ve Dağlı (2018) tarafından geliştirilen 24 soru önermesinden ve üç alt boyuttan oluşan örgütsel dedikodu ölçeği kullanılmıştır. Elde
edilmiş olan verilerin istatistiki analizleri için SPSS 21.0 veri analiz programı kullanılmıştır. Bulgular: Elde edilen bulgulara göre duygusal ahrazlık ve alt boyutları ile örgütsel dedikodu ve alt boyutları arasında (r=,388;
ile r=,503 aralığında p<0,00) düşük ve orta düzeyde pozitif yönlü anlamlı bir ilişki olduğunu tespit edilmiştir. Değişkenler arası etkileşim analizi sonucunda ise, duygusal ahrazlık algılamalarının, örgütse dedikodu algılamalarını
[(β=,975), (p<0.05)] (R2:,951; p: ,000) pozitif yönde etkilediği sonucuna ulaşılmıştır. Tartışma: Örgütlerde çalışanların duygusal ahrazlık sorununun örgütsel dedikodu üzerinde etkisinin olup olmadığının tespit edilmeye çalışıldığı
bu çalışmada, duygusal ahrazlık sorunu yaşayan çalışanların, örgütsel dedikodu eğilimindeki algılamaları etkileyebildiği, duygusal ahrazlık ile örgütsel dedikodu olgusu arasında ilişki kurulabileceğini söylemek mümkündür.

In the context of conservation, the government of Timor-Leste and its partners work together to implement an agroforestry program to address the problem of forest loss which continues to be graded every year. This study aimed to estimate the level of plant species diversity and the potential benefits of agroforestry for the Batara Village community. Data collection was carried out on agroforestry land owned by farmers in Batara Village from December 2021 to January 2022 and data collection using the single plot method and census method, namely 10m x 10m seedlings, 40m x 40m sapling, 60m x 60m pole and 113,14m x 113,14m tree. Data for plant diversity can be analyzed using the margalef index, shannon wiener, and evenness, and the potential benefits of agroforestry using descriptive analysis. Based on the results of research on the diversity of plant species in agroforestry land in Batara village, 33 species of seedling and understorey, sapling level 19 species, pole level 17 species, and tree level 15 species and overall found 42 species of plants with 25 families and the results of descriptive analysis of respondents' interviews show that agroforestry can contribute from an economic point of view by 54.28%, from an ecological perspective to 32.95%, from a social perspective to 24.18% and from a cultural perspective to 6.1%.

Peatland fire that occurred in 2018 are located in Kubu Raya Regency, West Kalimantan. The fire was claimed to cause the changes leading to peatland damage. The initial study based on samples collected in fire period reported that there were some changes of chemical properties leading to peatland damage. The study aimed to evaluate the  effect  of  land  fires on changes  in  some  soil  chemical  properties  after  two  years of  fires. Soil samples of fired and unfired peatland were subjected to soil analyses. Soil analyses covered soil pH, organic carbon (C), phosphorus (P), calcium (Ca), magnesium (Mg), potassium (K), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), and bulk density (BD). The results showed that after two years of peatland fires did not affect the changes of peat soil pH, organic C, P, Ca, Mg, K, Cu, Zn, Mn and BD. One plot of fired peatland  showed that the weight of frond and leaf area of oil palm grown on it was not statistically different from those of unfired peatland. The results suggested some chemical properties return to previous equilibrium due to high buffering capacity of peat soil.

Anemia is a nutritional problem that is often found throughout the world which does not only occur in developing countries but also in developed countries. Low iron intake often occurs in people who consume less diverse foods, such as protein. Iron deficiency anemia is more common in young women than young men because young women experience menstruation every month and are still in their infancy, so they need more iron intake. This activity was carried out at the Nurul Hakim Islamic Boarding School, Kediri District, West Lombok Regency in September with a target of 64 female students. This activity was carried out with the aim of increasing students' understanding of anemia. This community service activity was carried out by socializing using the lecture method, interactive discussions and filling out pretest and posttest questionnaires to see a comparison of the participants' understanding levels. The results of the service show that the understanding of the students of the Nurul Hakim Islamic boarding school towards the anemia material that has been announced has increased by 7% from the percentage of the initial pretest score of 56% and posttest of 63%.
