Eco-friendly bioplastic from Pontederia crassipes: cellulose and carboxymethyl cellulose biopolymers for sustainable, biodegradable bioplastic film
Authors: Abiyoga M , Saravana Kumari P. 
Published: January 2025

Expanded usage of polyethylene film in different industries lead to accumulation of plastics in the environment, which cause pollution and toxicity to life forms. It can be replaced by the bioplastics which are biodegradable, biocompatible, eco-friendly, and can be obtained from renewable sources at low cost such as plant weeds. The biopolymer, cellulose can be extracted from aquatic weeds since they are abundantly available from aquatic system, easy and safe to handle, and biocompatible. Pontederia crassipes an aquatic floating weed, widely dispersed in surface of polluted rivers and ponds. Directed to remove from water bodies by EPA due to its negative impacts on aquatic animal life and the collected biomass as such cannot be used as a feed due to the presence of polyphenols and nitrates. In the current study, about 30% of cellulose was extracted by delignification and bleaching of weed biomass collected from a river. Extracted cellulose was converted into another form of derived polymer, known as carboxy methyl cellulose (CMC) by treating with monochloro acetic acid. Biodegradable bioplastic was prepared using gelatin as gelling agent and glycerol as plasticizer by varying concentrations. Properties of the extracted cellulose, CMC, and bioplastic from cellulose and CMC, were analyzed by measuring film thickness, tensile strength, elongation point, FTIR, and antioxidant assay. About 25.7 µm thickness cellulose biofilm exhibited higher tensile strength of 55.3 MPa at dry, 45.5 MPa at wet condition and 24 µg/ml of antioxidant activity was observed. This research highlights the potential of utilizing water hyacinth, a typically problematic weed, to develop sustainable biopolymers that address the growing environmental concerns associated with conventional plastic waste. Thus, this research work provides a potential biological safe approach to prepare bioplastic film for commercial applications. While, gelatin is costly, a suitable, cheap alternative need to be identified to reduce the cost of production of the bioplastic film. However, further efforts are required to enhance the scalability of the product.
Water soil erosion under climate and land use change: current status and forecast
Authors: Golosov V. 
Published: January 2025

Under the conditions of a changing climate, slope runoff from arable lands undergoes varying degrees of significant changes in different parts of the temperate climate zone. The article, based on a review of published data and the author’s generalizations, examines the main trends in the transformation of soil erosion in the largest agricultural regions of the world with an emphasis on the European Territory of Russia (ETR). For ETR, based on observations of slope runoff during snowmelt, a clear trend of its reduction was revealed, starting from the 1990s up until the complete cessation of the forest-steppe zone in the west and its replacement by mixed snowmelt/rainfall erosion in the west of the steppe zone. A general reduction in the rate of soil losses within the southern megaslope of ETR was revealed for all landscape zones except for the south of the steppe zone based on estimates of the rate of sediment deposition in the bottoms of the dry valleys of first-order catchments. It is shown that climate warming contributes to an increase in the frequency of extreme rainfall events, which is especially significant in Western and Central Europe. This trend is still less evident within the ETR. Structural changes in land use have affected Russian agriculture to the greatest extent in recent decades. Here, up until the beginning of the 21st century, there was a significant reduction in arable land, which since the beginning of the second decade of the 21st century has been replaced by the restoration of arable land areas in the forest-steppe and steppe zones. In North and especially in South America, over the past two decades, zero tillage has been used on significant areas of previously arable land, which has significantly reduced the rate of soil erosion. At the same time, in a number of regions of the forest-steppe zone located within the East European Plain, since 2014, the share of row crops has increased sharply (up to 30 % of the total area of cultivated land), which has increased the likelihood of severe erosion.
The history of foundation and development of the Makkaveev’s laboratory
Authors: Chalov R. S. 
Published: January 2025

The N.I. Makkaveev Research Laboratory of Soil Erosion and Channel Processes was organized on the initiative of Professor N.I. Makkaveev in 1969 in accordance with the Resolution of the USSR State Committee on Science and Technology as a response to the Government Resolution “About urgent measures to protect lands from water and wind erosion of soils”. The paper presents that the basis of the new laboratory was formed by scientific teams (groups) created by N.I. Makkaveev since 1953 at Moscow University in various directions in the study of erosion and channel processes. Together with the development of the theory and methodology of erosion and channel studies, a unified doctrine of the erosion-accumulative fluvial process and erosion-fluvial systems, the laboratory’s research has always been closely linked to the solution of practical problems – protection of soils from erosion, regulation of river channels under development of water and other river resources, prevention of hazard manifestations of erosion and channel processes, on the one hand, and training of highly qualified specialists, on the other. The laboratory has overcome all the difficulties that have arisen in science development since the 90s of the 20th century and continues to function successfully at present, receiving support from the Russian Science Foundation, state and other programs, state contracts for the implementation of specific scientific and production tasks. The main scientific results of the 55-year activity of the laboratory are formulated.

ANALYZING THE COMMON MISTAKES HIGH SCHOOLERS MAKE WHEN USING THE SIMPLE PRESENT AND PRESENT CONTINUOUS TENSES
Authors: Lawalata Reiner JHG 
Published: January 2025

ABSTRACT
Learning English can be challenging due to the 16 tenses in English grammar, which describe events happening at different times. The most important tenses for English students to grasp are the simple present tense, which describes facts and recurring events, and the present continuous tense, which describes ongoing events. English is taught from elementary school to university level. The Community Service (PKM) aims to reinforce and expand students' knowledge of English, particularly focusing on the simple present tense and present continuous tense. Various teaching methods are employed in this learning process. This research serves to help teachers, students, future researchers, and anyone interested in teaching these tenses to identify common mistakes made by high school students. The research is based on students' work during PKM sessions at GKI Lachai Roi Hom-Hom Wamena, Papua Mountains, and the findings were analyzed qualitatively, supported by Ellis' error theory analysis method (2003). The research identified common mistakes in the use of the simple present and present continuous tense that need to be addressed by English students and teachers.

Introduction: African Animal Trypanosomiasis (AAT) is a haemoparasitic disease that considerably hampers socioeconomic development in sub-Saharan Africa. One way to counter this scourge is through vector control and treatment.
Objective: This study aims to help breeders in the study zone to control AAT.
Location and Duration of the Study: About three-year longitudinal follow-up was conducted in seven municipalities around Bamako city (Mande, Kalaban coro, Sanankoroba, Kati, Tienfala, Baguinéda, and Koulikoro) in district Bamako from March 2007 to December 2009.
Methodology: Thirty to fifty heads of cattle were randomly selected in each municipality, and depending on herd size, 5 to 10 heads of cattle were selected from each herd for examination. For each run, all animals diagnosed with Trypanosoma spp. positivity were systematically treated.
Results: A total of 7,622 blood samples from 312 cattle of different breeds (Peulh zebus, Metis, and Mereas predominant breeds) were collected and examined. A total of 106 animals were found infected with two Trypanosoma species (T. vivax, 99% and T. congolense, 1%). Prevalence was significantly (P<0.05) variable not only by breed (78.25% for zebu and nil for N'Dama) but also by year (4.47%, 0.53% and 0.1% in 2007, 2008 and 2009, respectively). Variability was also observed according to locality. However, this did not vary according to the sex of animal (P= 0.07). A total of 1691 doses of trypanocidal products were administered to infected animals.
Conclusion: As a result of treatment, the incidence and prevalence of the disease has decreased considerably. However, the risk of disease transmission remains, as biological and mechanical vectors are omnipresent in the area. Besides, seasonal animal movements are also a risk factor. Study suggests regular monitoring, vector management and trypanocidal treatment to reduce the disease incidence and improve livestock productivity.
Assessment of Selected Heavy Metals in Sediments from Ndambuk River, Busia County, Kenya

Published: January 2025

Anthropogenic activities have significantly contributed to soil and sediment pollution. Heavy metals are among the most common soil/sediment pollutants, owing to the fact that they easily get adsorbed on sediment surfaces and get carried from one ecosystem to another. This study examines the pollution effect of heavy metals in sediments from River Ndambuk, Busia County, Kenya. A total of eight heavy metals (Co, Cu, Fe, Cr, Ni, Cd, Pb and Zn) were examined during dry and wet seasons. The levels of Cd, Ni and Pb were above the World Health Organization (WHO) recommended limits for heavy metals in sediments. However, Pb levels were only above the WHO limit during the dry season, with the wet season registering concentrations way below WHO limits. Co, Cu, Fe, Cr and Zn recorded concentrations below WHO limits during the dry and wet seasons. Pollution indices were used to determine the extent of sediment pollution. Geoaccumulation index, pollution load index, contamination factor and enrichment factor were calculated from the heavy metal concentrations in sediments. Fe, Cr and Zn recorded negative I geo values during both seasons, signifying no pollution by these metals. Ni recorded moderately polluted to strongly polluted status whereas Pb recorded strongly polluted status only during the dry season. Points 1 – 4 recorded lack of pollution due to anthropogenic activities, while points 5 – 7 recorded pollution due to anthropogenic activities as per the PLI values. The study recommends proper land use and dumping of wastes and controlled mining activities to keep soil pollution at bay. Pollution by heavy metals can be controlled by embracing circular economy, which advocates for the reuse and reduction of waste to a minimum. Waste reduction will go a long way in reducing water and sediment pollution as the volume of pollutants discharged into water bodies will significantly reduce. The other principles of circular economy that will aid in mitigating water and sediment pollution include: regeneration of reagents, close water loops, integration of materials and waste flows, safe disposal of harmful elements, use of benign chemicals (which are less harmful to the environment) and reduction of chemical diversity.
