Authors: Ramayya N.
Published: May 2024

Seventy two Compositae belonging to 56 genera representing the thirteen tribes of the family have been investigated in this study, Trichomes are recognised broadly into two categories namely the 'vegetative' and the 'floral' ones. It is the former that have been presently taken up for detailed investigations. In all 35 trichome types are found so far in the family. Of these, 15 have been described by previous workers which the present author has also observed in the species under investigation. Another 13 are the newly established types by the author. The remaining 7 represent types which the author has not come across during the present investigations but are described in the literature.The general features of the trichomes in the family are discussed in the light of the present study. The trichomes are shown to exhibit in all four patterns in their structure which provide important evidence in the phylogeny of the trichomes.

Authors: Joseph J.
Published: May 2024

The study of the flora of Bori Reserve Forests, Hoshangabad District, Madhya Pradah has been undertaken during the years 1960 and 1961. The area stretches between 77Â°45' to 78Â°30' E. long. and 22Â°15' to 22Â°30' N. lat. on the southern slopes ef Satpura range. As a result of three seasonal visits 432 taxa belonging to 317 genera of 92 families could be collected and studied. The flora presents a typical dry deciduous type of vegetation without any change in the main components throughout. Some of the common species of plants in this forest are Anogeissus latifolia, Adina cordifolia, Aegle marmelos, Diospyros melanoxylon, Grewia tiliaefolia, Buchanania lanzan, Helicteres isora, Celastrus paniculata, Baliospermum montanum and Emblica officinalis. The area under study lacks in hydrophytic vegetation as there is hardly any perennial natural water source. Similarly orchids and ferns are also rare.

The Chemical Composition of some Waters from Slacks in Rameswaram Island, Madras State
Authors: Aggarwal K. R. , Mukherjee A. K.
Published: May 2024

Analyses of pH, total dissolved solids, CO,, HCO3, Cl, SO4, Ca, Mg, Na and K are presented for water samples from dune slacks in Rameswaram Island. Comparison of these analyses has been attempted with well waters from the area, sea water and world average fresh water. It is inferred that these slacks are under the influence of sea water but ion-exchange process similar to those in arid alkali soils appear to be responsible for Ca/HCO3 ratios of less than unity and Na/Cl and Mg/Cl ratios greater than those in sea water. Exceptionally high Na2Co3 and NaHCO3, contents in one of the slack waters is explained on the basis of sulphate reduction due to favourable conditions developed locally there.

Observations on the Pollination in Nechamandra alternifolia (Roxb.) Thw.
Authors: Ghosh M. K.
Published: May 2024

While studying the ecology of low lying lands in and around Calcutta, some observations were made on the mechanism of pollination in Nechamandra alternifolia, a common aquatic herb of Hydrocharitaceae. The mode of pollination in this plant indicates that the phenomenon is little influenced by the surface depression formed by tepals of the pistillate flowers. It takes place by the direct contact of the anthers of the floating male flowers on a calm surface of water with die stigmatic lobes of the female flower.

Authors: Bir S. S. , Shukla Prem
Published: May 2024

The paper deals with the taxonomic account of family Athyriaceae from Simla hills. Twenty one species are described and illustrated. The members of Athyrium nigripes group (A. nigripes, A. clarkei and A. setiferum) are characterised by the presence of setae on upper surface along costae and costules and possess non-perisporiate spores. The western Himalayan samples of Cystopteris fragilis possess rugoseverrucose spores in strong contrast to the spiny spores in several European examples. Athyrium mackinnoni is very distinct from A. nigripes under which its specimens have often been described. The Simla samples of Athyrium fimbriatum, in comparison to those from Darjeeling-Sikkim area, are of much smaller size and less divided. Diplazium polypodioides of the area is a polymorphic species and the different forms can hardly be taxonomically separated.

Phytogeographic Considerations on the Flora of Mt. Abu
Authors: Jain S. K
Published: May 2024

The Aravallis intersect the State of Rajasthan in a southwest-northeast direction. Mt. Abu on the Aravallis is the highest point in the wide gap between the Himalayas and the Nilgiris, and thus has phytogeographlc significance. The flora of Mt. Abu has been compared with that of other hilly regions of India, and also with the flora of adjacent regions of the dry zones. It is observed that : i. the flora of Mt. Abu has some representation of mountain element belonging to subtropical and temperate regions of India. This element comprises three groups of plants, namely, (a) those occurring in all or most hilly regions of India, such as in Himalayas, Parasnath, Pachmarhi, Western Ghats, Nilgiris, etc. (26 species); (b) plants found in the Himalayas or moist places of northern India, whose southern limit is the Mt. Abu (19 species); and (c) plants found in the Ghats and hills of Deccan Peninsula and whose northern limit of distribution is Mt. Abu 38 species).ii. there are only a few plants of alpine regions in this flora;iii. large number of plants are of wide general distribution;iv. biotic factors are resulting in increase of xerophytic species on this hill.A study ofthe world distribution of the plants of Mt. Abu shows that:i. out of 469 species, 267 are tropical;ii. 80 species are eastern, southeastern, Asian and Australian;iii, 46 species are African-Arabian; andiv. 22 species are American. The American plants are mostly weeds of cultivation.

Experimental biological studies of novel tetradentate hydrazone Cu(II) complexes for potential applications in medicinal chemistry
Authors: Topkaya Cansu
Published: May 2024

A series of mononuclear Cu(II) complexes were synthesized using a potential tetradentate hydrazone ligand obtained from the reaction between phenylhydrazine groups and 2,5-thiophenedicarboxaldehyde. The structures of ligands and complexes were elucidated through various spectroscopic techniques, confirming their composition. All complexes were found to adopt four-coordinated geometries, indicating the formation of stable structures. Spectroscopic analysis revealed that the hydrazone ligand coordinated with the Cu(II) metal ions as a dibasic tetradentate ligand by utilizing the phenolic oxygen and azomethine nitrogen atoms. The binding affinity of the complexes with calf thymus DNA (CT-DNA) was investigated using absorption and viscosity measurements, demonstrating their interaction through the intercalation mode. The binding studies showed that the Cu(II) complexes exhibited varying degrees of binding affinity, with Cu(L4) demonstrating the highest affinity, followed by Cu(L1), Cu(L2), and Cu(L3). Moreover, the DNA fragmentation properties of the Cu(II) complexes were evaluated, suggesting their potential utilization in pharmaceutical applications. The obtained results highlight the significance of these novel complexes in the field of medicinal chemistry.
Ab initio exploration of modified carbon nanotubes as potential corrosion inhibitors
Authors: Berisha Avni , Hadhlar Rajesh , Dagdag Omar
Published: May 2024

In order to develop novel unexplored potential corrosion inhibitors, covalently modified single-walled carbon nanotubes (SWCNT) via benzoic (–PhCOOH) and aniline (–PhNH2) groups are being investigated as corrosion inhibitors for the first time. Utilizing a comprehensive approach, this study employed density functional theory (DFT), Monte Carlo (MC), and molecular dynamics simulations (MD) to assess the adsorption behavior of modified nanotubes as corrosion inhibitors on the Cu(111) surface within a simulated aqueous HCl corrosion medium. The results provided molecular information on the adsorption capability, geometry adsorption centers, and adsorption energies (Eads) of carbon nanotubes on the surface of Cu(111). The adsorption energy values unveiled robust interactions between SWCNT–PhCOOH and SWCNT–PhNH2 inhibitors and the Cu(111) surface, suggesting a highly effective corrosion protection mechanism. The calculated Eads values exhibited notable ranges, spanning from –260.82 to –308.18 kcal/mol for SWCNT–PhCOOH and –220.92 to –261.01 kcal/mol for SWCNT–PhNH2 with the maximum probability values, representing the most favorable adsorption scenarios, determined to be –292.96 and –229.39 kcal/mol, respectively. A key insight from Monte Carlo simulations underscored the inherent spontaneity of the adsorption process, corroborated by the consistently negative Eads values. These findings collectively underscore the substantial affinity of the inhibitors to the copper surface, contributing to a deeper comprehension of their corrosion inhibition capabilities.

As an emerging technology, smart textiles can bring solutions to many problems, but also create new ones, especially related to their disposal and their impact on the environment. That is why it is important to address this problem at this stage of technological development when smart textiles have not yet pervaded the mass markets. In this article, first, an attempt is made to understand the chronological development of smart textiles: the reasons for a weak breakthrough in the commercial markets throughout the decades, starting from the 1990s until today, but also the emergence of new driving forces that should inevitably lead to a bright future for smart textiles. In addition, we explore the contemporary possibilities for sustainable materials, manufacturing techniques, and end-of-life solutions for developing sustainable smart textiles based on a broad literature review, online sources, and a questionnaire survey among textile experts. Finally, an overview of the latest developments related to the standardization of smart textiles is given. This research was spurred by participation in CONTEXT COST Action (CA17107 - European Network to connect research and innovation efforts on advanced Smart Textiles).

Published: May 2024

In the last decade, the most investigated perovskite materials are the hybrid organic-inorganic perovskites (HOIPs) due to their optoelectronic properties and possible application in the production of photovoltaics. This interest has led to an ongoing search for new HOIP variants, alongside thorough investigations of the properties of existing HOIPs. That is why our research in the field of organic-inorganic perovskites is aimed at the synthesis, characterization, and investigation of the electrochemical properties of dimethylammonium lead iodide (DMAPbI3) using voltammetric studies. A modified synthesis of DMAPbI3, differing slightly from the one described in the literature, was performed by combining stoichiometric amounts of lead iodide (PbI2) and dimethylammonium iodide (DMAI) dissolved in acetonitrile. After conducting controlled evaporation, a yellow crystalline powder of DMAPbI3 was obtained. The identity and purity of the obtained compound were confirmed by powder X-ray diffraction (PXRD), infrared (IR) and Raman spectroscopy, and scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDX). Investigations on the electrochemical properties of DMAPbI3 by cyclic voltammetry were performed with dichloromethane (DCM) and tetrabutylammonium chloride (TBAC) as the electrolyte. A paraffin-impregnated graphite electrode (PIGE) was used as a working electrode, on which the perovskite microparticles were immobilized. The electrochemical activity of DMAPbI3 is recognized through an intense, broad, and irreversible anodic peak attributed to the oxidation of the constituents to different possible products and the decomposition of the perovskite structure.
Phenolic fingerprint of Macedonian propolis

Published: May 2024

Propolis is a chemically complex resinous material collected by honeybees (Apis mellifera) from tree buds and resins, comprising plant exudates, secreted substances from bee metabolism, pollen and waxes. Its chemical composition depends strongly on the plant sources available around the beehive, which have a direct impact оn the quality and bioactivity of the propolis.
In this study, the composition of phenolic compounds in 13 Macedonian propolis extracts was investigated by HPLC-DAD-ESI-MS/MS. Overall, the UV spectra, the MS and MS/MS data allowed the identification of 36 compounds.
The major constituents of propolis were phenolic acids (caffeic and coumaric) and their esters (methyl, (iso)prenyl, benzyl, phenylethyl, cinnamyl), flavonols (quercetin, kaemferol), flavones (chrysin, apigenin, acacetin), flavanonols (pinobanksin) flavanones (pinocembrin naringenin, hesperetin, pinostrobin) and their methylated/esterified derivatives.
The results reveal that Macedonian propolis contains a diversity of phenolic compounds confirming that it is a poplar type of propolis with higher phenolic content (ranging from 43.75–637.94 mg/g) than reported in previous studies in the region and beyond in Europe (< 80 mg/g). This suggests the potential significance of Macedonian propolis as a valuable source of bioactive compounds with health benefits as well as for unlocking its economic potential for industry and beekeepers.

Published: May 2024

Corona virus disease 2019 (COVID-19) is a new disease caused by severe acute respiratory syndrome corona virus 2 (SARS-COV-2). The COVID-19’s symptoms are fatigue, muscle pain, and psychological disorders. The purpose of this study was to describe the occupational characteristics and health conditions of COVID-19 patients who had recovered after being treated at Udayana University Hospital. This study is a descriptive study with a quantitative method and cross-sectional design. The research samples were 110 COVID-19 patients treated at Udayana University Hospital from June to August 2020 and taken using random sampling. The results showed that the highest proportion of respondents were aged between 24-44 years (44.5%), with almost equal proportions of women (50.1%) and men (49.09%). Most of them lived in Denpasar (46.36%). Most respondents work as private sector employees (24.55%), and 70% of them were using personal protective equipment (PPE) while working. Most respondents needed less than seven days to return to work after being declared “in recovery state” (60%), with the remaining 55.5% having a decreased work duration to be less than 8 hours per day. The proportion of respondents with comorbidities was 30.91%. As many as 27.27% were experiencing previously similar symptoms (fever, fatigue, cough) 4 to 5 months after being declared “cured.” COVID-19 patients who have recovered should be monitored for a longer period of time to evaluate the symptom reoccurrence and its impact on their occupational and health conditions.

Indonesia is one of the Dengue Virus (DENV) endemic areas which are dominated by DENV-2 and DENV-3. Until now, no specific drug therapy has been found to cure Dengue Virus Infection (DVI). Punicalagin is one of the active compounds that have the potential to be used as an antiviral. Unfortunately, not many studies have used punicalagin as a DENV antivirus. This study aims to determine the inhibitory potential of punicalagin compounds against NS5 DENV-3 protein through molecular docking. Molecular docking was performed using AutoDock Tools, ChemDraw, and Discovery Studio Visualizer. The target protein used is NS5 DENV-3 protein with PDB ID code: 4V0Q. The ribavirin compound was used as a positive control. The results obtained show that the punicalagin compound has the ability to attach to target receptors in the C-Terminal domain complex. This docking produces a bond free energy (ΔG) of -6.39 kcal/mol. This result is better than the ΔG of the control compound. Punicalagin's Inhibition Constant (Ki) value also showed better results than ribavirin. So it can be seen that the compound punicalagin effectively inhibits DENV replication and has the potential as a DENV drug candidate.

Surgery can trigger systemic inflammatory response syndrome. This study aims to determine the effectiveness of Periplaneta americana cockroach extract as an oral systemic anti-inflammatory agent using molecular docking. The molecular docking method consisted of five steps. The first step was preparing the TNF-α converting enzyme (TACE) receptor as a native ligand, dexamethasone as a control ligand, and three test ligands of Periplaneta americana cockroach extract. The second step was docking preparation. The third step was analyzing Gibbs free energy (∆G) and root mean square deviation (RMSD). The fourth step was docking the test and control ligands with TACE. The fifth step was analyzing ∆G, inhibition constant (Ki), visualization of two- and three-dimensional interactions, percentage of binding site similarity (%BSS), and the rule of five (Ro5) on test ligands. The ∆G results for the native, control, and test ligands 1, 2, and 3 were -12.8, -7.1, -7.7, -6.9, and -9.0 kcal/mol, respectively. The Ki values for the native, control, and test ligands 1, 2, and 3 were 4.091, 6.205, 2.253, 9.521, and 2.507 µM, respectively. The results of the Ro5 analysis suggested that the three test ligands satisfied Lipinski’s rule of five. This study concluded that Periplaneta americana cockroach extract is an effective oral systemic anti-inflammatory agent.

Cryptosporidiosis is a waterborne zoonosis caused by Cryptosporidium, which is a parasite that causes infection of the small intestine and leads to acute diarrhea in both humans and animals. Wild rats (Rattus spp.) are known to carry many zoonotic pathogens including Cryptosporidium. Given their close proximity to humans in urban environments, the likelihood of disease transmission is high. This study aims to detect the Cryptosporidium spp. infection in wild rats in Surabaya City, East Java Province. Intestinal fecal samples were collected using necropsy. The flotation test and Ziehl-Neelsen stain were used to observe the presence of Cryptosporidium under the microscope. The results showed that 69 samples were positive for Cryptosporidium spp. in the oocyst stage, which appeared dark pink with a clear cavity and the size of the oocysts ranged from 2-6 μm. The high incidence of cryptosporidiosis in wild rats is a potential health threat to both animals and humans.

Lead (Pb) is a non-essential heavy metal that is toxic and has no known uses. Most cases of poisoning in livestock are caused by lead poisoning. This study aims to determine the effect of Coffea canephora bean extract as an antioxidant on the heart histopathological features of white rats (Rattus norvegicus) induced by lead acetate. This study used 25 male Wistar rats aged between eight and ten weeks and weighing between 200 and 250 grams. The rats were divided into five treatment groups, namely negative control (C-), positive control (C+), treatment one (T1), treatment two (T2), and treatment three (T3).  The results suggested that the administration of 200 mg/kg BW, 400 mg/kg BW, or 800 mg/kg BW of Coffea canephora bean extract was not effective in improving the heart histopathological features, including cell degeneration, hemorrhage, and necrosis, of rats induced with lead acetate at a dose of 2 mg/kg BW.

Published: May 2024

Aim: Multidrug resistance (MDR) is frequent in non-small cell lung cancer (NSCLC) patients, which can be due to its fibrotic stroma. This work explores the combination of pentoxifylline, an anti-fibrotic and chitinase 3-like-1 (CHI3L1) inhibitor drug, with conventional chemotherapy to improve NSCLC treatment.

Methods: The effect of pentoxifylline in the expression levels of P-glycoprotein (P-gp), CHI3L1 and its main downstream proteins, as well as on cell death, cell cycle profile, and P-gp activity was studied in two pairs of sensitive and MDR counterpart NSCLC cell lines (NCI-H460/NCI-H460/R and A549/A549-CDR2). Association studies between CHI3L1 gene expression and NSCLC patients’ survival were performed using The Cancer Genome Atlas (TCGA) analysis. The sensitizing effect of pentoxifylline to different drug regimens was evaluated in both sensitive and MDR NSCLC cell lines. The cytotoxicity of the drug combinations was assessed in MCF10A non-tumorigenic cells.

Results: Pentoxifylline slightly decreased the expression levels of CHI3L1, β-catenin and signal transducer and activator of transcription 3 (STAT3), and caused a significant increase in the G1 phase of the cell cycle in both pairs of NSCLC cell lines. A significant increase in the % of cell death was observed in the sensitive NCI-H460 cell line. TCGA analysis revealed that high levels of CHI3L1 are associated with low overall survival (OS) in NSCLC patients treated with vinorelbine. Moreover, pentoxifylline sensitized both pairs of sensitive and MDR NSCLC cell lines to the different drug regimens, without causing significant toxicity to non-tumorigenic cells.

Conclusion: This study suggests the possibility of combining pentoxifylline with chemotherapy to increase NSCLC therapeutic response, even in cases of MDR.
Advancing Electric Load Forecasting: Leveraging Federated Learning for Distributed, Non-Stationary, and Discontinuous Time Series
Authors: Richter Lucas , Lenk Steve , Bretschneider Peter
Published: May 2024

This paper addresses the evolving landscape of electricity markets in Europe, with a focus on the integration of Renewable Energy Communities as introduced by the Renewable Energy Directive 2018/2001. Residents within a postal code area are highly incentivized to join a community, which enables them to exchange energy among themselves at lower procurement costs. Thereby, energy management systems optimize the operation of respective energy systems, with electrical load forecasting playing a key role. Given that prosumers may switch between communities on a daily basis, electricity demands within these groups will vary, leading to data that is non-stationary, discontinuous as well as non-identical and independently distributed. To encounter this issue, we propose a sophisticated forecasting model that applies federated learning, using informations from various distributed communities to learn domain-invariant features. To achieve this, we initially utilize synthetic electrical load time series at district level and aggregate them to profiles of Renewable Energy Communities with dynamic portfolios. Subsequently, we develop a forecasting model that accounts for the composition of residents of a Renewable Energy Community, adapt data pre-processing in accordance with the time series process, and detail a federated learning algorithm that incorporates weight averaging and data sharing. Following the training of various experimental setups, we ultimately evaluate their effectiveness. The findings suggest that our proposed framework is capable of effectively forecast non-stationary and discontinuous time series and that it can be applied to new, unseen data through the integration of knowledge from multiple sources.

Published: May 2024

Manual material handling (MMH) significantly impacts worker health and productivity, often leading to musculoskeletal disorders (MSDs) primarily in the lower back. As a novel assistive technology, exoskeletons may serve as ergonomic tools to mitigate these work-related MSDs. It is essential to examine exoskeletons from the users’ perspectives before their widespread implementation in occupational settings. This study investigates the effectiveness of a passive back-support exoskeleton (BExo) in reducing perceived physical exertion and improving ergonomic safety in manufacturing context. Twenty-two college students were recruited to perform MMH tasks in a controlled lab environment, both with and without the BExo, followed by completing a survey questionnaire on various aspects of the BExo. Using ANOVA, the study analyzed biomechanical exertion across various body parts and tasks. The findings indicate that the BExo substantially alleviates discomfort in the low back, shoulders and knees, thereby, enhancing ergonomic posture and reducing fatigue. These results underscore the potential of passive exoskeletons to boost workers’ safety and efficiency, providing valuable insights for future ergonomic strategies in industrial setting.
Selective Mutism and Comorbidity with Specific Learning Disorders: Evaluation and Multimodal Intervention in a Clinical Case of a Female Child from 7 to 11 Years of Age
Authors: Capobianco Micaela , Costa Alberto
Published: May 2024

Selective mutism (SM) is an “Anxiety Disorder” characterized by a child’s “persistent inability” to communicate verbally in some (or all) contexts of social life that is associated with other cognitive-affective disorders. Cognitive-behavioural assessment and psychological intervention may be complex to be performed due to both the difficulty to administered standardized neuropsychological batteries (e.g., language-mediated tests) and the difficulty to involve family and teachers in the intervention program, respectively. Here, a single-case study is described in which a female Filipina child with SM underwent a comprehensive neuropsychological assessment and multimodal therapeutical intervention between the ages of 7 to 11 years. More specifically, the psychological intervention included cognitive-behavioral psychotherapy to both improve social-cognitive skills and learning abilities and to reduce anxiety, and speech therapy. Moreover, the parents and teachers were actively involved in the therapeutic process and they were also administered a psycho-education program. After this specific treatment, at the age of 11 years the girl began to verbalize in both therapy and school contexts, although she still was used to adopt non-verbal strategies. A parallel and gradual improvement in communicative-linguistic skills and school learning was also observed. In conclusion, the present report highlights the importance to apply an "integrated and multimodal intervention" to treat SM in children that includes also psycho-education intervention for both parents and teachers.
Exponential Convergence-(t, s)-Weak Tractability of Approximation in Weighted Hilbert Spaces
Authors: Chen Jia , Yan Huichao
Published: May 2024

We study L_2-approximation problems in the weighted Hilbert spaces in the worst case setting. Three interesting weighted Hilbert spaces appear in this paper, whose weights are equipped with two positive parameters $\ga_j$ and $\az_j$ for $j=1,\,2,\dots,\,d$. We consider the worst case error of algorithms that use finitely many arbitrary continuous linear functionals. We discuss the exponential convergence-(t,s)-weak tractability (EC-(t,s)-WT) of these L_2-approximation problems under the absolute or normalized error criterion. In particular, we obtain the sufficient and necessary conditions for EC-(1,1)-WT and EC-(t,1)-WT with t

Published: May 2024

Livestock farmers in the Limpopo Province benefitted from the land reform projects. This led to an increase in the number of emerging cattle farmers who desired to move from small-scale to commercial cattle farming. These emerging cattle farmers had high expectations for government support through extension and advisory services to improve the welfare of their cattle. However, the study aimed to investigate the perceptions of 80 emerging cattle farmers concerning the importance of agricultural extension and the impact of extension advisors in improving the welfare of their cattle. The study was conducted in 18 villages of the Sinthumule-Kutama areas under Makhado Municipality. The study used quantitative and qualitative methods and simple random sampling. Questionnaires were used to collect primary data. The Statistical Package for Social Sciences (SPSS) tool was used for analysis, and the mean score was produced to address the study’s objectives. The results indicated that farmers agreed on the importance of cattle welfare and that they are knowledgeable about it, and methods used by extension workers are essential. Furthermore, they decided that the extension activities contribute to their knowledge of cattle welfare. The paper concludes by making the following recommendations. Extension workers should collaborate with some of the farmers who are leaders within the community to manage cattle welfare when extension workers are not around. Cattle farmers of Sinthumule-Kutama are expected to be trained on livestock welfare.
