Synthesis and assessment of novel sustainable antioxidants with different polymer systems.
Authors: Mouren Agathe , Pollet Eric , Avérous Luc
Published: November 2023

Antioxidants are essential to the polymer industry. The addition of antioxidants delays oxidation and materials degradation during their processing and usage. Sustainable phenolic acids such as 4-hydroxybenzoic acid or 3,4-dihydroxybenzoic acid have been selected. They have been chemically modified by esterification to obtain various durable molecules, which have been tested and then compared to resveratrol, a biobased antioxidant, and Irganox 1076, a well-known and very efficient fossil-based antioxidant. Different sensitive matrices have been used, such as a thermoplastic polyolefin (a blend of PP and PE) and a purposely synthesized thermoplastic polyurethane. Several formulations were then produced, with the different antioxidants in varying amounts. The potential of these different systems has been analyzed using various techniques and processes. In addition to antioxidant efficiency, other parameters were also evaluated, such as the evolution of the sample color. Finally, an accelerated aging protocol was set up to evaluate variations in polymer properties and estimate the evolution of the potential of different antioxidants tested over time and with aging. In conclusion, these environmentally friendly antioxidants make it possible to obtain high-performance materials with efficiency comparable to that of conventional ones, with variations according to the type of matrix considered.
Three-Component Friedel–Crafts Alkenylation of Arenes and Heteroarenes with Ynamides and Iodine(III) Electrophile

Published: November 2023

The three-component Friedel–Crafts type functionalization of an arene using an alkyne and an electrophile can offer a strategy for rapidly increasing the molecular complexity of aromatic compounds. While conceptually straightforward, the implementation of this reaction manifold has been largely limited to unfunctionalized alkynes and electrophiles such as iodine(I) reagents. Here, we report the development of a three-component Friedel–Crafts alkenylation that utilizes a mix of ynamides and a cationic iodine(III) electrophile (benziodoxole triflate). The reaction proceeds quickly under mild conditions across diverse arenes and heteroarenes, producing α-aryl-β-iodanyl enamides in a regio- and stereocontrolled manner. The robust trans-selectivity of this iodo(III)arylation process is attributed to the reactivity of a highly distorted keteniminium species generated from the ynamide and the iodine(III) electrophile. The iodanyl moiety in these reaction products is amenable to a variety of transition metal-mediated coupling, thus offering access to densely functionalized enamides.

Published: November 2023

The ordering of solvent molecules around nanostructures is of broad scientific importance from understanding biological processes to the manipulation of nanomaterials in liquids, to optimiz-ing the performance of electrochemical devices. However, experimental measurements of this solvent ordering are scarce. Herein, the structures of concentrated solutions of anionic carbon nanotubes in two amidic solvents are measured via total neutron scattering leading to a previ-ously unattainable picture of nanoparticle solvation, revealing a far richer structure than hitherto assumed. The solvent molecules form densely-packed, concentric shells around the charged carbon nanotubes, ordered according to two distinct orientations due to competing effects. Firstly, a surface monolayer that maximizes attractive interactions between anionic surface and solvent molecular dipole moment. The second orientation extends ~40 Å into the bulk solvent, with molecules preferentially oriented perpendicularly to the first layer due to dipole interac-tions with the charged nanoparticle. This complex, long-ranged order drastically differs from the simplistic treatment of the solvent in classical models commonly employed to understand these systems. Moreover, our analysis indicates that a fraction of counterions condense on the sur-face as a Stern layer which are desolvated due to the solvent preferentially interacting with the charged surface. Ions at further distances are fully solvated, and their distribution is strongly in-fluenced by the dense solvation shells around the nanotube. Our results thus underscore the critical importance of multi-body interactions in solvated nanoscale systems, highlighting new competing ion/surface solvation effects crucial for understanding electrolyte-surface interfaces in supercapacitors, batteries, and electrolytically-gated devices.
Synthesis and spectroscopic investigation of substituted piperazine-2,5-dione derivatives
Authors: Stuart Craig D. , White Nicholas G. , Barrow Russell A. , Reekie Tristan A.
Published: November 2023

The piperazine-2,5-dione moiety is a useful scaffold for functionalisation to generate bioactive molecules. Synthetic methods for accessing substituted piperazine-2,5-diones involve cyclising dipeptides or building from the already established core. Utilising the latter method, we have developed procedures to condense a variety of methoxylated benzaldehydes to exclusively form (Z,Z)-(benzylidene)piperazine-2,5-diones 7. This methodology can easily be utilised to form both homo- and heterodimeric substituted piperazine-2,5-diones. Subjecting these compounds to hydrogenation affords two isomers. We detail simple NMR analyses that allow for identification of the cis or trans isomers. These analyses, combined with X-ray crystallography have shown that under the hydrogenation conditions used the cis isomer forms as the major product. The synthetic methodology combined with spectral analysis provides a valuable understanding of piperazine-2,5-dione properties.

Published: November 2023

This paper presents archival and published materials from the complex geoarchaeological site Malaya Syya, located in a promising area for studying the Paleolithic of Southern Siberia (at the junction of three large orographic structures: the Kuznetsk Alatau mountains, the Batenevsky ridge and the Chebakovo-Balakhta depression of the Minusinsk intermountain trough). The cultural horizons of Malaya Syya are included in deposits of complex genesis, which served as the general background for an ambiguous reading of the stratigraphic, chronological, and archaeological context of cultural remains. The development of archaeological knowledge in Siberia has made it possible to use more effective methods for studying the Malaya Syya assemblages from the point of view of attribution of the collection of stone and bone implements, chronological and planigraphic (spatial) determination. Returning to the early stages of studying this site, it required a detailed understanding of the sequence of formation of research hypotheses against the background of the general development of archaeological knowledge, analysis of the conclusions of researchers (V. E. Larichev, Yu. P. Kholyushkin, N. F. Lisitsyn, etc.) and an explanation of the reasons for the appearance such points of view. We have presented a detailed chronology of the history of research on Malaya Syya, based on the study and analysis of archival materials (archives of the Field Research Department of the Institute of Archaeology RAS, archives of the Institute of Archaeology and Ethnography SB RAS) and published data. It seems to us that the early stages of research on Malaya Syya were dominated by the position of V. E. Larichev’s selfless desire to preserve the destroyed object within the framework of the Iyus Archaeological Reserve. The history of the study determines the key problems of modern understanding of the general process of sedimentation at the site Malaya Syya, geostratigraphy, geochronology, paleontology, characteristics of the archaeological context and attribution of collections, issues of adaptation of the ancient population in specific nature conditions. The current materials and results of research on the site are presented in a series of sequential publications, which are expected to be presented in a monographic study.

Accuracy of digital terrain model on forest roads using airborne LIDAR and UAV point clouds
Authors:   University of Žilina, Kardoš Miroslav , Ferenčík Michal
Published: November 2023

A sufficiently dense forest road network is a basic prerequisite for the professional management of forests on the basis of close to nature management. For the purposes of forest management, it is of great importance to determine the state of damage of forest roads, to plan their reconstruction and to calculate the costs of their repair. The dominant method for forest mapping is photogrammetry, which is currently combined with airborne laser scanning data. The combination of these two methods makes it possible to obtain up-to-date and representative forest and landscape information for the purpose of professional and sustainable forest management in the context of 'precision forestry', which is based on the use of detailed site-specific information for the planning, management and implementation of forestry activities. In this paper, we discuss the application of the mentioned remote sensing methods for modelling the surface of selected forest road sections and evaluating the elevation accuracy of the data used. From the point of view of the methods used, both appear to be very suitable for the purpose of detailed surface mapping, condition and damage assessment, or for the optimization and design of new roads.

STRATEGI LAYANAN BIMBINGAN DAN KONSELING BERBASIS CYBER COUNSELING
Authors: Alfira Aina , Nur Syaifullah
Published: November 2023

Abstact: The research approach used in this study is a qualitative descriptive approach. Qualitative research is research that intends to understand the phenomenon of what is experienced by research subjects, for example behavior, perceptions, motivations, actions and others. The approach or strategy of this research uses a phenomenological approach and data collection methods in this study, namely observation, interviews and documentation. The use of cybercounseling can benefit counselors and counselees from a time and financial standpoint, because the counseling process is not limited by space and time, whenever and wherever the counseling process can be carried out. In addition to the advantages of cybercounseling, it also has weaknesses which until now are still the starting point for criticism from various groups, for example implementation procedures. Besides that, the weakness of cybercounseling is that the counselor does not have enough attention to pay attention to facial expressions, counselee's body language and verbal cues, lack of dynamics, and cannot be clearly controlled behaviors that weaken the dynamics of counseling.Keywords: Service, BK and Cybercounseling
Important pollinator species for conserving rare plant species endemic to San Clemente Island, California
Authors: Hazlehurst Jenny , Calloway Stephanie , Knapp Denise
Published: November 2023

Much effort has been spent on the conservation of rare, threatened, and endangered plants in the biodiversity hotspot of the California Floristic Province, however little is known about the identity of their pollinators. In this study we provide the first formal study on the identity of the invertebrate pollinators of five rare endemic island plant species from San Clemente Island, the southernmost of the California Channel Islands: Delphinium variegatum ssp kinkiense, Lithophragma maximum, Malacothamnus clementinus, Malva assurgentiflora ssp glabra, and Sibara filifolia. We surveyed plant-pollinator interactions at populations of each focal plant species using timed sweep-netting. We used pollinator capture data to compile bipartite interaction networks for each plant population, and calculated centrality indices (degree, betweenness centrality, and closeness centrality) of pollinators to identify species important to network stability. We found a significant effect of pollinator taxonomic group (fly, bee, wasp, or Lepidopteran) on some indices of pollinator centrality in interaction networks, and variation in pollinator centrality between different locations. Hoverflies, moths, and butterflies were important generalists with higher network centrality across all plant populations, while bees tended to be more specialists within their networks, except for the Malva assurgentiflora ssp glabra network, where bees were on average of higher centrality than flies. We recommend targeted restoration practices for future study that could support pollination both directly and indirectly to focal rare plant species of conservation interest across plant populations. These practices could augment general pollinator conservation best practices such as reducing pesticide use and planting native plant species to provide increased pollination to endangered plants.

Published: November 2023

The results of the research conducted in the form of a mass online survey of Russian youth in 2022 are presented. The aspects of digital socialization in the ratio of virtual and real interaction are described. The distribution of opinions of young respondents about the role of digital technologies in their lives and the extent to which these technologies can replace the factors of real, "live" communication is presented. The authors conclude that young people are ready to actively interact in two spaces – digital and real, which allows us to consider the model of socialization that closely unites them as the most acceptable at present.
Research field of demographic security in the multi-ethnic space of narratives of students
Authors: Solovarova Yu. N.
Published: November 2023

The demographic situation in Russia is characterized by a persistently narrowed type of population reproduction, which certainly actualizes the study of narratives on demographic security and involves understanding the attitudes and risks associated with demographic behavior. Kazan universities are a good platform for studying the demographic behavior of student youth, where mutual influence of the attitudes of the Turkic world and the Russian mental context occurs. The article discusses the features of using the focus group method in the research field of demographic security, with students of Kazan in a multiethnic youth environment. As a result of conducting 16 cases using the focus group method and based on 50 free interviews with its participants, which were conducted 7 days after each focus group, the key attitudes of demographic behavior (reproductive, self-preservation, migration and matrimonial) of student youth in a multi-ethnic environment were identified and the image of the future in demographic security narratives. The focus group method is presented as a platform that makes it possible to create a certain “meta-story”, where the demographic attitudes of young educated representatives of different ethnic groups are realized, the degree of their compatibility, and a search for ways of a possible joint future is developed..

Published: November 2023

It is known that transient receptor potential (TRP) channels are receptors for reactive oxygen species and components of cigarette smoke, and therefore may be involved in the pathogenesis of chronic obstructive pulmonary disease (COPD).

Aim: To investigate the expression of TRPV1, TRPV4, TRPM8 and TRPA1 channels on peripheral blood leukocytes of COPD patients and healthy individuals and to establish its possible relationships with inflammatory markers and lung function parameters.

Methodology and Research Methods. 23 patients with COPD of varying severity and 17 individuals without bronchial obstruction were examined. The expression of TRP channels on monocytes, lymphocytes and granulocytes was determined by indirect flow cytometry. Plasma concentrations of cytokines were measured in a multiplex assay. Lung function parameters were assessed by spirometry.

Results. Monocytes from COPD patients were characterized by increased expression of TRPV1 (98.8 (97.6; 99.6)% vs. 97.8 (96.3; 98.6)%, p = 0.03) and TRPA1 (99.2 (98.7; 99.8)% vs. 95.1 (94.2; 98.4)%, p = 0.003). In addition, COPD was associated with an increased ratio of TRPV4/TRPM8 expression on monocytes (0.66 (0.51, 0.90) vs. 0.27 (0.12, 0.70), p = 0.02) and granulocytes (0.97 (0.86; 0.92) vs. 0.29 (0.06; 0.89), p = 0.003). TRPV4 expression on monocytes showed correlation with CXCL10 level (ρ = 0.55, p = 0.01), and for TRPM8 inverse relationships were found with the concentrations of IL-6 (ρ = –0.56, p = 0.02) and IL-10 (ρ = –0.55, p = 0.02). We did not find any associations between the expression of TRP channels and lung function parameters.

Conclusion. Increased expression of TRPV1 and TRPA1, as well as an increased TRPV4/TRPM8 ratio on peripheral blood monocytes of COPD patients may indicate the contribution of these receptors to the proinflammatory activation of the cells and indicate possible prospects of TRP channels pharmacological modulation for the purpose of the disease therapy.
Force-Feeding: Consumption and Sexuality in Frank G. Paci's Black Madonna
Authors: Paulgaard Shelby
Published: November 2023

Informed by calls to re-evaluate the relationship between Canadian literature and power in the wake of Canada’s sesquicentennial, this paper examines Frank G. Paci’s Black Madonna, a 1982 Italian-Canadian novel that played a significant role in early discussions of Canadian multiculturalism. This paper reassesses Paci’s representation of the protagonist Marie, a second-generation Italian-Canadian woman. Using Judith Butler’s concept of the construction of the gendered body and Julia Kristeva’s theory of abjection, this paper analyzes Marie’s struggle for bodily control and her rejection of her Italian mother’s ideals about food, sexuality, and family. Through applying this framework of gender performativity and abjection of Otherness, this paper argues that Marie’s disordered relationships with food and her sexuality are a result of the pressure on second-generation female immigrants to perform cultural identity while simultaneously assimilating into Anglo-Canadian culture. I contend that Marie’s rape fantasies and sexually transgressive encounters are indicative of the corporeal tensions faced by female immigrants in Canada, while her bulimic abjection of Italian food acts as a physical manifestation of the abjection of immigrant cultures by both Canadian multiculturalism and second generation immigrants within multiculturalism. This reassessment of Black Madonna provides a framework for re-reading early multicultural texts through a more nuanced understanding of the relationship between multiculturalism, gender, sexuality, food, and trauma.

Mixed Cropping-A Review
Authors:   Millets Specialist and Genectics ,Coimbatore, G.N RANGASWAMI AYYANGAR , M.A SANKARA AYYAR ,   Assitant Millets Breeding Station Coimbatore
Published: November 2023

Mixed cropping is a system of Agriculture in which two or more crops are grown together at the same time in the same land. It is a common practice in tropical countries both with annual field crops and with perennial plants like fruit trees, flower plants and plantation crops. This type of cropping prevails in Africa, India, Ceylon, Malaya, China and West Indies. It is also usual to grow annual herbaceous crops in the midst of woody perennial trees of economic importance such as coconut, mango, jack and other fruit trees. "The group of plants growing together form a plant society like the natural plant societies that occur on any piece of land leit to nature." (Willis, 1909).

Status of the crop in the State. Banana is the name used in foreign countries for the Indian plantain (whether used as fruit or vegetable). The crop is not important commercially in the Mysore State even though there is considerable demand for the fruits, especially in the two principal cities of the State, Bangalore and Mysore. The demand for bananas is mostly met from supplies received from Salem and Trichinopoly Districts of the Madras Province. The main varieties imported into these cities are Poovan, Rasthali, Vamanakeli and Monthan. Poovan, Vamanakeli and Monthan are obtained mostly from Mohanur on the Cauvery bank in the Salem District and from Trichinopoly in the Trichinopoly District. Rosthali is got mostly from Thotliyam and Karur in the Trichinopoly District. The price of both fruit and vegetable varieties is comparatively high especially in the two cities. where the fruits of Chakkarakeli, Rasthali, Vamanakeli, Chenkadali and Monthan are in great demand.
Economic Aspects of the Problem of Nutrition in India
Authors:   Tamil Nadu Agricultural University Coimbatore  641 003, W.R AYKROYD
Published: November 2023

Within the last 30 years science has reached definite conclusions as to what constitutes a good diet for human beings. The principles of correct feeding are fairly well understood and "optimum" dietary standards based on these principles have been drawn up by League of Nations Commissions and other suthoritative organisations. Now generally speaking a "good" diet-i. e., a diet which approaches or attains the physiological optimum-costs more than a diet which fails at various points to satisfy human nutritional requirements, and consequently there is a close correlation between the economic status of a family. or population group and the physiological value of its diet. In a sense this is a platitude, perhaps better expressed in a simple phrase such as "the poor can't afford to buy enough of the right sort of food to eat". But a more detailed analysis of the relation between income and diet than such a phrase provides helps in the understanding of the problem of nutrition in India.
Marketing of Fruits with Special Reference to Grapes in the Madura District and Suggestions for its Improvement

Introduction. Of late, there has been a cry from scientists and leaders of thought "Grow more fruits" and "Eat more fruits". Experts in diete- tics are also of opinion that at present the use of fruits as one of the items of our daily food is quite inadequate and that deficiency of fruits and fruit products in the diet is highly detrimental to the health of the people. The backwardness of the Indian farmer in adopting scientific methods of fruit growing is recognised as an impediment to the production of fruits on a large scale. The lack of marketing facilities and the proverbial ignorance of marketing conditions by the fruit grower, add to the deterioration of the fruit-growing industry. It is, therefore, considered necessary that for en- suring and stimulating the health of our people, improvements in scientific farming must go hand in hand with the improvement in the method and disposal of the produce. The marketing of fresh fruits, their transfer from the producers to the consumer, is an important and indispensable activity. It involves a varied and often complex distribution and sales system, and it is usually costly. It is due to the uncertainties of the trade, the risks in- volved and the various services performed in modern distribution and marketing. Accordingly the difference in price between what the grower receives for his product and what the consumer pays is often considerable indeed. Marketing of fruits is attended by various groups of people, buyers, wholesalers, jobbers, retailers, etc. Each successive middleman specialises to some extent in a particular function and service. There is, however, con- siderable overlapping in the activities of the various agencies and a con- tinuous adjustment in methods of distribution especially since the advent of the use of motor bus, lorries and train service in transportation. The system is sometimes made simpler by a "link" or middleman being dropped out, but occasionally it becomes more complex due to the necessity of interpo- sing a new agency between the existing ones.

A grass survey of the Travancore State was made by the author between 16th November and 6th December 1941. Though Travancore State is just equal in area to a large district of the Madras Pro- vince, the ecological features exhibited are very diverse, ranging from sub- temperate to tropical. The elevation varies from sea level to about 9,000 feet in. height at Anamudi which is the highest point in South India. The State forms a narrow strip of country between the sea and the ghats. It has a long coast line on the western side and rises gradually to the Western Ghats which form the eastern boundary. The climate in most parts is humid due to the long coast line, presence of backwaters, lagoons, innumerable canals and rivers and also to the heavy rainfall received in the major portion of the State. The high ranges of the State have a semi-temperate climate. One half of the country is covered with mountains and many rivers take their origin from them and fall into the Arabian Sea on the western side. The soil in most parts of the State is reddish being of laterite formation. Due to the undulating nature of the country the land is subjected to both sheet and gully erosion. The fine particles of the soil are carried away by the rain water to the rivers and deposited in the backwaters and the sea. The land is, therefore, comparatively poor and the soil is deficient in mineral contents The substratum consists of gneiss while that of the adjoining British Indian districts except Malabar consists of limestone commonly known as kankar. The soil is, therefore, further deficient in calcium.
The Puddler

The "puddler" is an ingenious agricultural implement. It is used primarily for puddling and secondarily for trampling leaf manure in wet- lands for paddy cultivation. it is, therefore, a dual purpose implement. Just as a tank is the main weapon on land to win a war so is this puddler- now nicknamed wetland tank - for the successful cultivation of paddy with the minimum labour on maximum area within a minimum time limit. It was introduced in the Hindupur Taluk of the Anantapur District for the first time in 1940 by the Agricultural Department when the price of each was Rs. 21. Its price now is Rs. 36 which is beyond the means of an ordinary cultivator. This original implement is of all iron parts consisting of galvanized iron pipe 3 feet long, 3 cast iron hubs of 4 spokes each to take in iron plates, flat iron handle and frame and a number of bolts and nuts that cannot be made or repaired by a village smith. Due to war the price of iron as everybody knows has gone up and a time has now come when the minimum quantity of iron will have to be used for such implements.
Degeneration of Improved Crops in India.
Authors:   Imperial  Agricultural Research Institute, New Delhi, B.P PAL
Published: November 2023

When an improved variety of an agricultural crop is released for general distribution among cultivators by the Agricultural Departmant. sooner or later a report generally follows that the improved variety has deteriorated or degenerated. Farmers, dealers and commercial seed growers complain that the acre-yield of the improved variety has gradually decreased or that the variety has deteriorated in quality, a few years after its introduction. As the cultivator's return ultimately depends upon the quantity and the quality of the crop he grows, it is of paramount importance to consider the various causes that may lend to the degeneration of an improved variety and to find out such measures as can be practised by the cultivator and the plant breeder to reduce it.
Insect Enemies of the Cashewnut Plant (Anacardium occidentale) in South India

Though an exotic species the cashewnut plant has gained a strong foothold in this country, especially along the coastal and submontane areas of the West Coast from the Cape in the South to almost as far as Bombay and in different parts of the Coromandel Coast. Due to great de- mand for the cashew kernels from outside countries, thousands of acres of waste land which have been left uncultivated till recently have been planted up with this tree and year after year new areas are planted up. This is a tree which is found to grow well in almost all kinds of soils, and especially in well drained rain led hill sides and the sandy coastal tracts; it begins to bear well and give a good return in about six to eight years. Prospective planters of this crop will, however, do well to bestow suffi- cient care and precaution towards the healthy growth of the tree free from diseases and pests to which this crop is frequently subjected. As the area under this crop is bound to increase year after year in proportion to the growing demand, the chances for pests and diseases to multiply are great, as has been the experience with crops like sugarcane and groundnut in S. India. While even in the case of several crops like those mentioned above, pests of minor importance in the old days have begun to assume the status of major pests, in perennial plants like mango, cashew or other trees such pests have greater chances of rapid multiplication and wider distribution when the area under the food plant increases rapidly and no attention is paid to these pests in the early stages. In this paper an attempt is made to give a brief account of the different insects associated with this plant, their bionomics as far as we know and a few suggestions towards their control.
Rabies and its Control in India.
Authors:   Civil Veterinary Hospital, New Delhi, M.R SHARMA
Published: November 2023

Rabies is one of the oldest known diseases. It is found in nearly all parts of the world and in all climates. It has not so far been introduced into Australia or New Zealand and has been stamped out of the British Isles by the destruction of all animals infected with the disease, or suspected to be so infected, by the muzzling order, and by strict quarantine regulations concerning the import of dogs. Once the symptoms have developed, it ends fatally almost always. It is also a source of imminent danger to human life and domestic animals, causing considerable economic loss. To apply suitable measures of control against this disease it is essential as in the case of many other diseases, to have a thorough public awakening. Rabies is primarily a disease of wild and domesticated canines, e. g. dogs. jackals, foxes and wolves, but all the warm-blooded animals like cattle, horses, goats, sheep, cats, monkeys, rabbits, camels, elephants, fowls and human beings are susceptible. Infected canines particularly parish dogs, so widely and exten- sively distributed in India, spread the disease among themselves and other susce ptible animals and human beings. The mongoose and blood sucking (Vampire) bat have been reported to net as a natural reservoir of rabies virus in South Africa and South America respectively and to convey the infection to domesti- cated animals and human beings; but in India the virus is usually maintained by wild carnivores and stray dogs.
