Authors: SINGH D B , AHMED NAZEER , SINGH S R , MIR K A , LAL S
Published: August 2023

The levels of total chlorophyll and carotenoids were determined in kale (Brassica oleracea L.) leaves of three commercial cultivars, i.e. Siberian Kale, Khanyari and Japanese Green. The investigation was carried out at Central Institute of Temperate Horticulture, Srinagar, J & K in two successive years (2009-2010); in each year raw material was obtained in three harvests carried out 5, 7 and 9 weeks after planting young kale transplants in the field. During whole period of investigation the range of average content of chlorophyll in 100g fresh weight was 136.18 g in Siberian Kale to 172.10 g in Japanese kale. In all the cultivars chlorophyll content significantly increased from first to second harvest and maximum of 3.5% increase was in Japanese Green and subsequently decreased in third harvest. Similarly level of carotenoids in different cultivars varied significantly and maximum of 23.50 mg/100g as observed in Japanese Green and minimum of 18.99 mg/100g in Siberian Kale. Similarly significant difference was recorded with harvest dates and interaction of harvest date and cultivars. The increase of carotenoids from first to second harvest was recorded maximum (12.90%) in Siberian Kale and increase from second to third harvest was maximum in Khanyari (12.12%).

Authors: KAUR RAMANJIT , JAIDKA MANPREET
Published: August 2023

A field experiment was carried out to distinguishing Malva neglecta from wheat (Triticum aestivum L.) crop based on their spectral reflectance characteristics through remote sensing during rabi seasons of 2010-11and 2011-12. The investigation consists of six treatments each having different population levels of Malva neglecta, viz. 0, 3, 6, 9, 12 plants/m2 and a treatment having pure population or solid stand of Malva neglecta. The results indicated a decreasing trend in effective tillers, number of grains/ear, 1000-grain weight and grain yield of wheat with increasing population densities of Malva neglecta from 3 to 12 plants/m2. Highest grain yield of wheat (5.75 tonnes/ha) was recorded under pure wheat treatment (solid stand) and lowest grain yield (3.24 tonnes/ha) was recorded in treatment having 12 plants of Malva neglecta/m2. Higher radiance ratio and NDVI values were recorded in pure wheat treatment and minimum in pure weed treatment. It was observed that by using radiance ratio and NDVI, pure wheat can be distinguished from pure populations of Malva neglecta after 30 DAS and remain distinguished up to 120 DAS and different levels of weed population can be discriminated amongst themselves from 60 DAS onwards. From the study it was concluded that remote sensing technology can be used for identification of different weed species and their infestations in field crops. Weed prescription maps can be prepared with Geographic Information System (GIS), on the basis of which farmers can be advised to take the preventive control measures.

Published: August 2023

Adoption behavior of farmers is affected by the attitude they possess for particular technology. Many grape growers became successful exporters by associating themselves to Mahagrapes, necessitating need to study their attitude scientifically and empirically. Study of 90 grape growers who were members of cooperatives linked to Mahagrapes, from Nashik, Sangli and Pune districts of Maharashtra found that members had long association with Mahagrapes with average of 15 years. They earned average Rupees 13.3 lakh per annum by exporting their produce. Average land holding was 10 acres and productivity of grapes obtained was 11.7 tonnes/acre. Farmers had more favourable attitude towards grapes cultivation as result of their association with Mahagrapes. Total annual income, risk taking behavior and achievement motivation of members were positively and significantly related to attitude towards grape cultivation and export. Thus, study implied that farmer's organization like Mahagrapes helped in developing positive attitude among farmers towards grape cultivation and export, motivating them to earn more income annually by exporting their produce.

Published: August 2023

Pokkah boeng (Fusarium moniliforme J L Sheldon) is a minor fungal disease in sugarcane (Saccharum officinarum L.), characterized by malformed leaves. The disease incidence was surveyed at two locations in Haryana (Karnal and Kaithal) from 2010 to 2013. Chlorotic phase infection was prevalent in the study area. The percent disease incidence ranged from 6.90 to 25.30%, the highest incidence was recorded during 2013. A total of 138 subtropical sugarcane varieties, 40 pre-release clones and 182 exotic clones were screened against the disease under natural epiphytotic condition at Karnal. Most of the clones (80.83%) were resistant (120 clones out of 360) or moderately resistant (171 clones out of 360) to pokkah boeng. Subtropical varieties such as BO 137, Co 0238, CoH 110, CoJ 83, CoJ 85, CoS 8432, CoS 8436, CoS 88230, CoS 03251, CoS 03252, CoSe 95436, CoSe 01434 and UP 0097 were moderately susceptible hence strong seed health programme is suggested to contain the disease. Fourteen clones, viz. Co 425, Co 12027, Co 10036, Co 0331, M 165/38, H 45-2120, B 46-199, Q 64, PR 1058, CP 81-1384, F 65-554, POJ 6688, EPC 37-069 and H 44-3098 were susceptible to pokkah boeng hence this information may be taken into account while deciding the merit of the clones for hybridization. Autumn planted canes manifested less disease incidence than spring planted canes. Canes around field border and broad leaved clones showed higher disease incidence. However, the incidence did not vary between plant crop and ratoon crops. There were no association between pokkah boeng incidence and top borer attack but their combined damage would be detrimental to the crop. About 92.67% of pokkah boeng infected plants recovered growth, without fungicide spray, as the age of the crop advances and with change in weather.

Published: August 2023

The fundamental aim of this study was to investigate the assessment of accounting policy choices on accounting practices in Nigeria. The survey research design was used for this study, and the population was the total number of accounting and related practitioners in Nigeria, which was categorized as an infinite population. However, samples of 672 were chosen using a multistage non-finite population method. The structured questionnaire was used as the primary source of data, and data was collected using a Google form. The words in the questionnaire were carefully chosen to address the study's primary objectives. The questionnaire was divided into two sections, A and B. Section A contained biographical information on the respondents, whereas Section B contained remarks about the study's objectives or hypotheses. The response options were a 5 likert scale system with Strongly Agreed, Agreed, Undecided, Disagreed, and Strongly Disagreed scored from 5 to 1. For descriptive statistics, a basic frequency table was utilized, whilst analysis of variance (ANOVA) and ordinary least squares (OLS) were used to draw conclusions from the hypotheses developed. Cronbach's Alpha was also employed to determine the internal consistency of the scale used along with the research items. The result showed R of 76.0% which indicates a very positive and strong model. The overall fitness of the model is established based on the outcomes of the study which showed that the three aspects of accounting policy choices have a joint significant influence on Nigerian enterprises' accounting practices (F= 76.001, p-value =0.000). The study concluded that the three dimensions (revenue recognition, depreciation and inventory valuation policies) of accounting policy choices all have significant influence on accounting practices of Nigerian firms. Therefore, this study recommended that Nigerian firms, corporate or otherwise should ensure that appropriate income recognition policy be se

Analysis of PADDD: an environmental econometric application
Authors: Menezes Gláucio Costa de , Fontgalland Isabel Lausanne
Published: August 2023

The environment has always been a great source of raw material for humanity, whether this matter is of plant, animal, or mineral origin. The vast majority of needs are met through factor-factor and factor-product correlations, which indicate in their genesis the nature of economic development. However, numerous scientific works, especially those produced by scholars of the economic sciences, demonstrate that some resources made available by nature are finite, and it should therefore be sought to develop strategic measures so that their use occurs in the most rational way possible. Among these strategies is, since the 1970s, the creation and dissemination of so-called "protected areas", whose main scope is the preservation of the environment for future generations.
Performance of solar stills integrated with PV/Thermal solar collectors: A review
Authors: A. Jasim Maryam , K. Ahmed Omer , Alaiwi Yaser
Published: August 2023

All Earth's life forms depend heavily on water. Despite the critical importance of fresh water in the modern world, water pollution caused by industry and increasing urbanization has significantly reduced the amount of pure water available on Earth. Changes in global climate and seasons also contribute significantly to the depletion of fresh water resources. Population growth over the past few decades has increased the demand for safe drinking water. Multiple water-borne diseases can result from drinking contaminated water, and depending on the level of pollution, this could even be fatal.  There are several ways to purify polluted water, but solar distillation is the most cost-effective and environmentally friendly option because it mimics the hydrological processes seen in nature and can be powered by the sun alone. Solar stills provide drinkable water and don't call for any special expertise to operate or maintain.  An integrated PV/T solar still is a welcome solution for distant locations that already struggle with access to safe drinking water and dependable electricity. According to research, a passive solar still produced 2–5 kg/m2 of fresh water daily whereas an active solar still connected to a PV/T collector could produce 6–12 kg/m2 of fresh water daily. In this paper, we provide a complete investigation of the solar still coupling and PV module coupling levels at the moment.

Published: August 2023

Researchers are looking at alternative cleaner technologies to fulfill the rising need for greener fuels. For this reason, alternatives like bioethanol and biodiesel have become commercially available. Renewable fuels are classified as either "first generation," "second generation," or "third generation" depending on the feedstock used in their manufacture. Over the past decade, society's reliance on first-generation biofuel feedstocks has created an inbuilt rivalry between food and fuel. Second-generation biofuel feed-stocks, such as non-edible agricultural waste products, energy crops, and crop residues, have been illuminated by emerging technical prospects. Technologies for producing biofuels have been proposed and developed in multiple stages, with first-generation technologies being the most developed. In several nations, including the United States, corn grain is used as feedstock in bio-refineries. There is a risk that food and fuel prices will rise as a result of the usage of edible materials in crops like corn. Second-generation biofuel manufacturing technology that utilizes crop residues has been developed to deal with this kind of problem. This study investigates and evaluates the economic viability and environmental sustainability of the proposed solution for the production of second-generation biodiesel.
Cholestasis gravidarum in women in the second and third trimester of gestation, clinical and specific pharmacological treatment and its benefits. An evidence-based approach
Authors: Nobre Da Silva Lorran , Estrin Marcelo Adrian
Published: August 2023

Introduction: Cholestasis gravidarum is a syndrome that usually occurs in pregnant women in the second or third trimester of gestation and ends in the puerperium. It is clinically characterized by the presence of predominantly nocturnal pruritus that is initially palmo-plantar and then generalized. With alterations in liver function with or without jaundice and elevated serum bile acid levels, biochemical cholestasis is classified as mild to moderate severity. Objective: Diagnostic methods and pharmacological treatment approaches that provide the best results for these patients. Methods: Systematic review using the terms MESH (cholestasis of pregnancy) that generated 2597 results. Results: 28 papers were analyzed in more detail, of which 12 papers were finally selected for the final analysis. Treatment: Ursodeoxycholic acid (UDCA), a beta epimer of chenodeoxycholic acid, is a bile acid more polar than primary bile acids, with substantial choleretic and other multiple chemoprotective effects. The mechanism of action is not completely understood, but studies have shown that after treatment there is a reduction in total serum bile acids in both maternal and cord serum and a qualitative change in the serum bile acid pool. When compared with all controls, UDCA was also found to be associated with a decrease in the incidence of preterm birth, neonatal respiratory distress, and the number of neonatal admissions to intensive care units. Conclusions: The treatment of cholestasis gravidarum is oral administration of ursodeoxycholic acid is effective and safe in the treatment of patients with cholestasis gravidarum.

Authors: Stopa Couto Marina , Estrin Marcelo Adrián
Published: August 2023

Background: Acute pancreatitis is a sudden inflammation of the pancreas with the possibility of presenting severe complications. Diabetes is a chronic metabolic disease, the cause of a large part of global morbidity and mortality. Approximately 90% of patients with diabetes suffer from type II diabetes. Several studies were carried out in this regard, and with fairly large samples in quantitative terms. Within the treatment of type II diabetes there are hypoglycemic agents, of which there is a group called gliflozins or also inhibitors of sodium-glucose cotransporter 2 (SGLT2is) such as canagliflozin and empagliflozin. Methods: A systematic review of the literature available in databases such as PubMed was carried out, carrying out specific investigations to identify case reports of acute pancreatitis associated with the use of gliflozin. For this, an exhaustive reading of all the available articles was carried out. Results: Of the 4 articles analyzed, the average incidence of pancreatitis in patients who used gliflozin was 0.38%. Conclusion: We conclude that it is not possible to establish a causal relationship between the use of gliflozin and acute pancreatitis.

Background. Insect pests, as well as other arthropods, constitute a constant threat to public health and food security and food sovereignty in a country. Although various techniques are currently used for integrated pest management, the search for new management alternatives is constant. In this sense, transcriptome analysis, which consists of the analysis of gene expression profiles of certain living organisms, could provide new alternatives. Objective. To determine the potential applications of transcriptomic analysis against insect pests in the agricultural sector in Panama. Methodology. The study was developed through the search for relevant information on transcriptome analysis applied within entomology. Search was performed in SciELO (Scientific Electronic Library Online), Dialnet, Web of Science, Springer Link, Ciencia.Science.gov, Scopus, Google Schoolar and ERIC (Institute of Education Sciences). Main findings. The analysis of transcriptomes is a tool to understand different biological, physiological, and molecular aspects of insects and other arthropods identified as pests in the Republic of Panama that put at risk the agricultural production of the country. Implications. Harmful arthropods have become more relevant in recent years due to climate change, invasive species and anthropogenic factors that increase the populations of these pest in Panama. Conclusion. The results indicate that transcriptomic analysis generates information about the existence of candidate genes, including those of harmful arthropods and natural enemies as predators, parasitoids and entomopathogenic microorganisms that could be used as targets to reduce the damage caused by arthropods to the agricultural sector.

Published: August 2023

Background: In Colombia, most traditional cocoa crops are developed under agroforestry systems (SAF), associating shrubs and trees that provide shade for cocoa. They generate additional economic income and various ecosystem services. Objective:  To characterize agroforestry systems with cocoa in three municipalities in eastern Boyacá (Miraflores, Berbeo, and Páez) belonging to the province of Lengupá. Methodology: A semi-structured interview was applied in 15 selected farms to learn about socioeconomic aspects, agronomic management of cocoa, and the use and management of trees. The botanical and structural composition and the Simpson (S), Shannon-Weaver (H´), and Jaccard (J) plant diversity indices were determined. Results: Cocoa producers in that region develop smallholder production under agroforestry systems with irregular tree species distribution, which are used for wood, firewood, shade, and food. At the regional level, 189 forest individuals accompanying cocoa were found, grouped into 18 families, 17 genera, and 28 species. The municipality of Berbeo presented the highest abundance (73 individuals), followed by Miraflores (67) and finally, Páez (49). In Berbeo, the species with a high importance value index (IVI) were Ceiba pentandra and Cedrela odorata (35 and 33, respectively), in Miraflores Trichanthera gigantea and Persea americana (44 and 42) and, in Páez Cedrela odorata (104). Implications: The selective felling of forests in SAF with cocoa, which intensifies the production of wood, has favored the loss of diversity; Therefore, the floristic composition studies serve as a basis to identify other potential forest species for the establishment of SAF to promote the diversification of the productive system and contribute to its resilience and sustainability. Conclusion: The agroforestry systems with cocoa in three municipalities in eastern Boyacá presented a differential composition and diversity, marked by a lower diversity in the municipality of Páez, where the species C. odorata had greater representation, related to the affinity of farmers for timber species of commercial interest.

Safety and aesthetic outcomes of using fillers with different cross-linking agents. A case report.
Authors: Menkes Sophie
Published: August 2023

Of the several dermal fillers developed in recent decades, hyaluronic acid fillers have become the material of choice. They are safe, long-lasting, non-immunogenic, available to most patients, and can be removed with hyaluronidase. Unfortunately, early and delayed complications can also occur after HA filler injection. Below, we present the case of a 42-year-old patient who had complications after the aesthetic procedure using hyaluronic acid dermal fillers in the past. Surprisingly, the treatment performed with hyaluronic acid cross-linked with another cross-linking agent was without complications. The affected places were the chin and malar area. In 2021, after performing augmentation with hyaluronic acid in the chin area, a patient developed swelling, which subsided after using hyaluronidase (Hylase Dessau 300 I.E.) and corticosteroids. The patient repeated the procedure in 2022, where she was administered 2 ml of hyaluronic acid in July 2022. About 3 weeks after injection, oedema and nodules appeared at the injection site in the zygomatic/malar area; after using Prednisone, the changes subsided. In September 2022, 3 ml of PEG-cross-linked hyaluronic acid was successfully performed with no side effects. In the described case, an important role was played by the ability of the hyaluronic acid hydrogel to modulate human immunological functions, which was associated with a very low risk of immune-related side effects and accompanying cellulitic processes.

This research aimed of investigate the effects of foliar applications using different levels of herbicidal potential from two bacterial species and five aqueous plant extracts on the yield and yield components of Oryza sativa L. and Echinochloa crus-galli L. The study followed a split factorial design based on randomized complete block design (RCBD) with three factors and three replications during the 2017-2018 crop year. The primary treatments consisted of aqueous extracts from Sorghum, Broccoli, Nettle, Eucalyptus and Elderberry, as well as Streptomyces sp-albos containing thaxtomin, Xanthomonas campestris, and control s (without aqueous plant extracts and surfactant). The secondary factor involved foliar application treatments with varying levels of concentration, including zero (control), 5, 10, and 15 per thousand extracts and the third experimental factor included Oryza sativa L. and Echinochloa crus-galli L. The findings revealed that as the extract concentration increased, plant height, leaf area index (LAI), grain yield, biological yield, chlorophyll a, chlorophyll b, and total chlorophyll contents decreased. Conversely, grain starch content increased with higher extract concentrations, with the most pronounced effects observed at 15 per thousand extract concentration. It was also observed that the use of extracts led to reduced yield characteristics and components in both Oryza sativa L. and Echinochloa crus-galli L. Among the extracts, Elderberry extract exhibited the most significant negative impact.  Comparatively, Oryza sativa L. demonstrated higher plant height, LAI, grain yield, biological yield, harvest index, chlorophyll content, grain protein content, and grain starch content when compared to Echinochloa crus-galli L. The results suggested that various extracts, particularly Nettle, along with 15 per thousand concentrations of Elderberry and Nettle extracts, hold potential for controlling Echinochloa crus-galli L. during the germination stage under field conditions.
On open neighborhood energy of graphs
Authors: K A Harikrishnan , K Manilal
Published: August 2023

The open neighborhood of a vertex u denoted by N(u) in a simple connected graph G is the collection of all vertices other than u and adjacent to u. In this paper, we introduce a square matrix of order n, called the open neighborhood matrix, ONM(G) of a graph G whose (i, j)th entry is |N(vi) ∩ N(vj)|/(di+dj) whenever vi~vj,  i≠ j; and zero otherwise, where di and dj, are the degrees of vi and vj respectively. We then establish the relationship between the connectedness of the graph G and the multiplicity of the eigenvalue zero of the matrix ONM(G), if it exists. Furthermore, we found the bounds for the largest open neighbourhood eigenvalue and open neighbourhood energy of graphs.

Authors: Ram Sonu , Dharmarha Preeti
Published: August 2023

In this paper, we investigate the class of totally (m, n)-paranormal operators on Hilbert space and prove some additional properties of totally (m, n)-paranormal operators on Hilbert space. Also, we show that Weyl's theorem holds for operators in this class. Moreover, we also show that for totally (m, n)-paranormal operators, the Weyl spectrum satisfies the spectral mapping theorem.
On the base locus of linear systems of general double points
Authors: Ballico Edoardo
Published: August 2023

Fix integers n ≥ 1, d ≥ 4 and  x>0 such that (n+1)(x-1) +Bin(n+2, 2) ≤ Bin(n+d, n). Take a general S ⊂ Pn such that #S=x and let B denote the scheme-theoretic base locus of |I2s(d)|, where 2S is the union of the double points with S as their reduction. Then 2S is the union of the connected components of B containing at least one point of S. We prove this theorem proving that a general union of x-1 double points and one triple point has no higher cohomology in degree d.

Published: August 2023

Let {Nn}n≥0 be the Narayana's cows sequence given by N0 = 0, N1 = N2 = 1 and
Nn+3 = Nn+2 + Nn, for integers n ≥ 0
and let {Un}n ≥ 0 be the generalized Lucas sequence with parameters integers a ≥1, b =±1 given by U0 = 0, U1 = 1 and
Un+2 = aUn+1 + bUn, for integers n ≥ 0.
In this paper we give effective bounds for the Diophantine equation Nm =Un, in positive unknowns m and n. We then solve explicitly that equation with Fibonacci, Pell and Balancing sequences cases.

Authors: Aruldoss A. , Selvaraj Chelliah
Published: August 2023

Let f: A → B and g: A → C be two ring homomorphisms and let J and J' be two ideals of B and C, respectively, such that f-1(J) = g-1(J'). In this paper, we give a characterization for the amalgamation of A with B along J with respect to f (denoted by A ⋈f J) to be a SITT-ring and also we give a characterization for the bi-amalgamation of A with (B, C) along (J, J') with respect to (f, g) (denoted by A ⋈f,g (J, J')) to be a SITT-ring. We also give some characterizations for strong weakly SIT-rings.

On Lie-Rinehart-Poisson algebras structures
Authors: Moukala Norbert Mahoungou , Bossoto Basile Guy Richard
Published: August 2023

We define the Schouten-Nijenhuis bracket on the algebra of the module of Kahler differentials. We give the main features of Poisson manifolds by using the universal property of derivation. We prove the equivalence between a Lie-Rinehart algebra structure and a Poisson structure and we recover Lichnerowicz's notion of Poisson manifold. We show that a symplectic Lie-Rinehart algebra structure induce a nondegenerate Poisson structure and conversely.
Algebraic structure of plenary train algebras of rank 4
Authors: Bayara Joseph , Coulibaly Siaka
Published: August 2023

In this paper, we study plenary train algebras of rank 4 admitting an idempotent. We obtain the Peirce decomposition of these algebras relative to an idempotent and the product of the associated Peirce components. The effect of changing an idempotent is discussed under the e-stability hypothesis. We show that a back-crossing algebra is a plenary train algebra of rank 4 if and only if it is a principal train algebra of rank 4. Finally, we study the particular case of monogenic back-crossing train algebras.

Authors: Tenkodogo Joseph , Savadogo Souleymane , Conseibo Andre , Dembega Abdoulaye
Published: August 2023

In this paper, we give the necessary and sufficient conditions for an evolution algebra to satisfy a train identity of degree 2 and exponent 3. We show that this class of algebras is a subclass of the Bernstein algebras of order 2. Then, we study the relations existing between these algebras and the Bernstein algebras as well as the power associative algebras. Moreover we give a classification in dimension ≤ 4 of evolution algebras satisfying strictly a train identity of degree 2 and exponent 3. Finally, we describe the derivations and automorphisms of these algebras.

Habitat preference of Geometridae species in Western Black Sea region of Turkey (Lepidoptera: Geometridae)
Authors: Özdemir M.
Published: August 2023

In this study, 3399 specimens belonging to 188 species of the Geometridae (Lepidoptera) family were examined. Species composition and abundance rates of Geometridae communities were analyzed with respect to the plant formations of the region as deciduous forests, dry coniferous-oak forests, humid coniferous forests, pseudomaquis and farmlands. The results also indicates that 26 species in deciduous forests, 23 species in coniferous-oak forests, 20 species in humid coniferous forests, 20 in pseudomaquis and 20 species in farmlands have high abundance rate. The highest rates of abundance in deciduous forests and dry coniferous-oak forests belong to Cyclophora linearia (Hübner, [1799]) with 14,7% and Peribatodes rhomboidaria ([Denis & Schiffermüller], 1775) 13,1%, respectively. Also, the highest rates of abundance in humid coniferous forests and pseudomaquis belong to Scotopteryx moeniata (Scopoli, 1763) with 23,46% and Cyclophora puppillaria (Hübner, [1799]) with 19,83%. Species richness is much higher in deciduous forests than it is in other habitats. Faunal similarities between the Geometridae communities are reported below 50% among all habitats. The highest faunal similarity was found to be between dry coniferous-oak forests followed by the second highest similarity between pseudomaquis and deciduous forests.
