Group variability of the morphological features of the leaf of Betula pendula Roth (Betulaceae, Magnoliópsida) in the gradient of weather conditions and technogenic soil transformation
Authors: Zhuikova T. V. , Meling E. V. , Popova A. S.
Published: June 2023

The group variability of morphological features of the leaves of Betula pendula Roth was studied in the gradients of adverse weather conditions and technogenic soil transformation. The studies were carried out on the territory of the Tagil zone of the Middle Urals in 2016–2019. It has been revealed that most of the studied leaf traits have an average level of variation, while a high one is characteristic of the shape index, and a low one is characteristic of the leaf blade index and the angles between the main and lateral vein of the first order, located in the middle and upper parts of the leaf. In the gradient of deterioration of weather conditions, the variability of the features increases, whilst it decreases in the gradient of technogenic soil transformation. The morphological features making the greatest contribution to the variability of the size and shape of the leaf were identified by the method of principal component analysis. Leaf variability is mainly determined by dimensional features. Allometric features are more stable. To assess the resistance of an organism to adverse factors, it is proposed to use the stability coefficient, which reflects the number of trait transitions from one level of variability to another one. This indicator increases both in the gradient of technogenic soil transformation and in the gradient of unfavorable weather.
Yellow-breasted bunting Ocyris aureolus (Pallas, 1773) (Aves, Passeriformes) in the Northern European Russia
Authors: Preobrazhenskaia E. S. , Amosov P. N.
Published: June 2023

Our studies of the distribution and abundance of the yellow-breasted bunting (Ocyris aureolus) were carried out on the territory of the Arkhangelsk region and in certain bordering areas of the Komi Republic in 2001–2022. A total of 57 meadow and meadow-swamp territories were surveyed, and a number of them – repeatedly in several years. In 2001–2011, the yellow-breasted bunting was found in almost all the surveyed territories, except some dry meadows and extreme northeastern floodplain lands in the lower reaches of the Mezen river. But already in these years, there were trends towards a decrease in its numbers, as indicated by the records carried out in the floodplain of the Pinega river for several years. In subsequent years, the yellow-breasted bunting was recorded on vast grasslands in the floodplains of large rivers only. A relatively high density was observed only in three (out of 35 surveyed) sections of flood meadows, in the floodplains of the Northern Dvina river and Vaga river. In most of the territories where it was found, only 1–3 individuals were recorded. In addition to dry meadows, it has ceased to occur in small-area floodplain meadows. Since the habitat conditions of the yellow-breasted bunting at the northwestern borders of its range have not changed significantly, the cause for this decrease in its numbers there can be considered the deterioration of habitat conditions during the flight and wintering.

Published: June 2023

Background The anatomical and histological features oblige the Lungs to be most susceptible to invasions. Lung lesions are common due to exposure to various risk factors. A few of them are pollution, smoking, human immunodeciency virus (HIV), infections, tuberculosis, and malnutrition. An increasing trend in cases of lung cancer is being seen in India. Lung biopsy is a simple, relatively safe, rapid and reliable technique for the diagnosis of pulmonary mass lesions, particularly with the aid of computed tomography (CT) scan. We wanted to study the histopathological pattern of lung lesions along with its distribution with regard to age, sex, and site. Methods This is an observational study conducted at the Department of Pathology, ESIC Medical College, Kalaburagi from January 2020 to December 2022. Material for the study consisted of all the biopsies submitted for histopathological and immunohistochemical study. Results 164 cases were included in the study, out of which 104 cases (63.41%) were malignant, 10 cases (6.10%) were of inammatory origin and 50 cases (30.49%) showed no evidence of malignancy. Male to Female ratio was 3:1. Most common age group was 51 to 60 years (31.71%). Most common histological type of malignancy was adenocarcinoma (36.54%), followed by squamous cell carcinoma (30.77%). Conclusions Lung biopsy is reliable with high accuracy for diagnosis and subtyping of lung lesions. Immunohistochemistry is an important complimentary tool for routine diagnosis of lung cancers.

Published: June 2023

Goal. To investigate the effectiveness of fungicidal control of the most common onion diseases during the growing season.
Methods. Informational and analytical (collection of materials and analysis of literary sources), field research (setting up experiments, carrying out treatments and records of plant damage by diseases, monitoring the development of plants, harvesting), phytopathological (determination and identification of pathogens), mathematical and statistical (processing of results studies). Experiments were conducted on different varieties and hybrids using modern fungicides with different active substances.
Results. During the years of research, onion crops were dominated by mycoses, namely, peronosporosis, alternaria, stemphylliosis, and fusarium wilt. Downy mildew and leaf spots were observed on all varieties and hybrids. The investigated fungicides most effectively controlled the development of downy mildew of onions. Their efficiency during the growing season averaged 55.1—100%, depending on the drug, the degree of disease development and the variety. The highest effectiveness against downy mildew of onions was provided by fungicides Fandango 200 ES, KE (fluoxystrobin, 100 g/l + proteoconazole, 100 g/l) at the rate of 1.25 l/ ha and Signum VG (boskalid, 267 g/ kg + pyraclostrobin, 67 g/ kg) — 1.5 kg/ ha. Fungicides were 45.8—89.1% effective against leaf spots (alternaria and stemphyllosis), 57.9—70.5% against fusarium wilt. Treatments with fungicides, due to the reduction of plant damage by diseases, contributed to the increase in onion yield by 1.3—6.9 t/ha, depending on the variety and preparation. Among the studied varieties, the highest yield was obtained on the Medusa variety (40.7 t/ha), among fungicides, the highest yield increase was provided by Fandango 200 ES, KE fungicide (1.25 l/ha).
Conclusions. Fungicides effectively controlled the main mycoses of onion (peronosporosis, alternariosis, stemphyllosis and fusarium wilt) during the growing season. The effectiveness of fungicides against onion diseases was 45.8—100%, depending on the type of disease, drug and crop variety. The highest protective effect of fungicides was provided against downy mildew of onions. The yield of the researched varieties and hybrids increased by an average of 5—25% due to the reduction of plant damage by diseases. The highest technical efficiency against identified diseases and increase in onion yield was obtained by using Fandango 200 ES, KE fungicide with a consumption rate of 1.25 l/ha.
TINJAUAN TENTANG HARGA DAN UKURAN DALAM JUAL BELI (EKSPOR) BENIH LOBSTER MENURUT HUKUM DAGANG DAN UNDANG-UNDANG PERMEN-KP NO.1 TAHUN 2015

Published: June 2023

Pelaksanaan praktik jual beli Benih Lobster yang terjadi pada saat ini diduga belum sesuai dengan Hukum positif. Pada praktik jual beli tersebut khususnya dalam ekspor, terdapat beberapa pihak yang merasa dirugikan, seperti halnya Nelayan, dan juga Negara Republik Indonesia sendiri, karena harga yang ditetapkan oleh penjual belum sesuai dengan apa yang telah ditetapkan oleh Undang-Undang. Dalam hukum positif sendiri dalam jual beli benih lobster ada aturan dan ketetapan jenis dan ukuran dalam jual beli lobster laut. Namun sangat disayangkan beberapa nelayan saat melakukan profesi mereka tidak memperhatikan efek kedepannya, yang dimana sebagian nelayan ada yang melakukan transaksi jual beli benih lobster tidak sesuai kebijakan yang telah dibuat. Ditakutkannya pula ini akan berdampak pada tingkat ekonomi khususnya dalam jual beli biota laut, terutama untuk hewan lobster. Dikarenakan, bewan tersebut menjadi incaran para nelayan sebab harganya yang jika dijual lumayan mahal dan rasanya sendiri bila dikonsumsi sungguh nikmat sehingga permintaan pasar akan hewan tersebut terus menerus tiada henti. Oleh sebab itu, pemerintah membuat kebijakan yang telah diatur dalam Peraturan Menteri Kelautan dan Perikanan Nomor 12 Tahun 2020 tentang Pengelolaan kepiting dan lobster di wilayah NKRI.

Territorial governance as synergic capital in the development of local latin american production systems
Authors: Pokolenko Ana Alicia
Published: June 2023

Based on the recognition of the challenges that have led to a paradigmatic shift in the logic of managing territorial development strategies and the theoretical assumptions generated around it, this study delved into the understanding of territorial governance in Latin American contexts by analyzing the intangible capitals present in local productive systems. The hypothesis was that a positive cohesion of these capitals in a governance scheme would allow for the activation of development processes in the system. After a critical and analytical investigation of the theoretical postulates and available experiences, it was concluded that governance, as a management model, is key to stabilizing intangible capitals in complex productive systems such as those in Latin America. The activation of synergistic capital in these systems is hindered by constant "short circuits," so strengthening these capitals through collaborative governance is essential to improve coordination and transparency in decision- making and thus generate territorial development processes.

The paper provides the results of the study of component, structural group analysis of the hydrocarbons and the resin of residual fraction of >350 оC condensate from Shahdeniz field. The residue is divided into the groups of saturated (naphtenic-paraffin), aromatic hydrocarbons and the resins of liquid-adsorption and eluent-replacement chromatography on the activated silica-gel. The spectral analysis, the method based on the data of elemental composition, on the average molecular weight and data of PMR were used to specify the structural group composition of separate components. The average molecular weight was defined via the cryoscopy in naphthalene. The studies justified that the saturated hydrocarbons derived from the residues are a complicated mixture of cyclic, normal and isomeric structures. The alkyl part of an average molecule is equal to 2/3. ~33 % of an average molecule falls to the share of cyclopentane and cyclohexane rings. The aromatic hydrocarbons of the residue are characterized with high content of alkyl radicals. The resins present a complicated mixture of mono- and two-block molecules, in each block of which 5.86 naphtenic, 2.11 aromatic rings with short alkyl substitutes are condensed.

The lithologic-petrographic and reservoir characteristics of Maikop sediments are studied in detail. Maikop sediments in this region are characterized with tufogenic-sedimentary complex of large thickness, layered clay slates, clays, aleurites, sandstones and conglomerates; clay rocks are dominant. Maikop sediments underwent facies changes in vertical and horizontal directions: the lower part of Maikop suite is characterized with clay, and the upper one – with sand and tufogenic facies. The sandstones of Upper Maikop sediments are defined with better filtration- capacity properties than those of Lower Maikop. The research of these rocks has a special significance for the specification of direction of the exploration surveys.

The practice justifies that the most oil fields are characterized with numerous parameters in the operation process. The pressure, phase permeability, volumetric flow rate by the phases are some of them. The changing of parameters, as a result, drastically effect the productivity of the oil wells. By course of time, the pressure drop leads to the seperation of gas from fluid in formation conditions, i.e. if the bottomhole pressure is lower than saturation pressure, the degassing takes place at the bottomhole zone, which increases the permeability of gas phase.
Ground water resources of Azerbaijan and their efficient use
Authors:   Azerbaijan University of Architecture and Construction, Hasanova N.F.
Published: June 2023

The paper is dedicated to the surface water resources of Azerbaijan and their efficient use. Azerbaijan is in the list of the countries with small water supply. Compared to the other countries of the South Caucasus, the water resources of Azerbaijan are limited and comprise only 15 % of water resources of the whole region. The water percent per head of the population in Azerbaijan is on the lowest level compared to the other Republics. The main reason for this is various locations of water sources. The estimated reserves of water in our country are equal to 30.9 bln. m3, of which 33 % is local, and 66 % - the water formed due to the transborder rivers. The contamination of Araz and Kur rivers, the major water sources, by the neighboring states worsens the situation. To meet the demand of the crop plants in irrigation water, the amount of the agricultural water should be increased. Therefore, the supply of farm lands with water is directed to the implementation of the different water-related activities, as well as to the engineering-melioration and other organizational issues with the purpose of rational use of the water.
On the use of solar energy in Azerbaijan
Authors:   State Agency on Renewable Energy under the Ministry of Energy of Azerbaijan Republic, Abdullayev J.S.
Published: June 2023

The paper deals with the “solar energy”, one of the areas of green energy in detail. In the modern world, the solar energy is considered the most perspective source of alternative energy with a great potential. The solar technologies turn the sun rays into the power energy via the photovoltaic (PV) panels or the mirrors accumulating solar radiation. The solar panels are used to obtain the power from solar energy while solar collectors are used for the heat and hot water supply. Solar panels are the devices developed from the light-sensitive semiconductor materials and turning solar energy into the power through the photoelements consisting of several layers in a general frame. Moreover, the movement of power energy depends on how high the light intensity is. The solar energy is produced via the the solar panels as the direct current (DC), and subsequently, power transisters – inventors turning this energy into the alternating current (AC) are used to integrate it to the network. In addition, the author marks that Azerbaijan has high potential of solar energy, as well as the projects implemented in this sphere by the State. The stations in the balance of the “Azalternativeenergy” LTD under the State Renewable Energy Sources Agency – Wind Power Station under Gobustan Hybrid Power Station, Solar and Biogas Power Stations are operated conjointly. Surakhany, Pirallahy, Sahil, Samukh, Sumgayit Solar Power Stations are described in detail. At the same time, it is noted that solar generation devices with small power have been installed by “Azalternativeenergy” LTD in thirteen social facilities, through which power supply and seasonal heat supply in nineteen social facilities are carried out as well.

The productivity of the wood grinding process can be increased by using abrasive wheels with spherical corundum grains. They also expand the area of application of rigid abrasive instruments by reducing soiling and eliminating burns on the treated surface. The studies revealed several advantages of the abrasive wheels over sanding paper: very precise processing, achievement of the desired grade of the treated surface, high durability of the instrument, and low cost. A force analysis of a grinding surface with micro-cuttings made of spherical corundum grains was performed depending on the degree of its wear. The results revealed that chip removal by the spherical corundum grains was possible only under certain conditions when the cutting edges of the grains were exposed. Besides, the theoretical dependencies of forces in micro-cutting were obtained from every principal condition for the process of grinding wood and wooden materials: properties of the spheres, treatment modes, and material-related factors. The special properties were analyzed by the chip formation process and self-sharpening conditions of the spherical corundum wheels. The grain size had the greatest influence on the thickness of chips which were cut by one grain. The grain content and bonding, like other properties of the internal volumetric structure, had a less substantial impact. The abrasive tool characteristics must complement the processed material, such as grain size, hardness, and structure. On the other hand, spherical corundum has optimal physical and mechanical properties for grinding, particularly the thickness of the grain’s edges, which primarily determine the material’s tensile strength. The grinding depth and feed rate mostly define the parameters of the grinding performance of wood and wood-based materials. An increase in those leads to a rise in cutting forces, roughness of the ground surface, a reduction in the grinding length over the period of the wheel’s durability, and the grinding coefficient. If the grinding depth and feed rate are constant, the performance can be improved by increasing the cutting rate.

Published: June 2023

Aspen and poplar are the least required types of wood in the Russian Federation, whose stock is continually expanding. Such wood can be used as a substitute for valuable hardwood, but in this case the strength must be almost doubled while achieving stability in shape and size. Treatment with acetic anhydride, polyvinyl alcohol, polyethylene glycol, or hydrothermal care are the most common methods for maintaining the volumetric stability of the wood. Treatment with phenol- and urea-formaldehyde monomers, oligomers, and resins is typically done for strength improvement. The stabilization of the dimensional parameters is especially critical for pressed wood, which has 8 times greater swelling in water than raw wood. Cardanol was chosen as a modifier. It can be derived from cashew nutshell liquid or synthesized. The established technique for impregnating wood with cardanol includes 2–3 % acetic acid, followed by heat treatment at 140–150 °С for 6–8 hours. During this process, cardanol polymerizes with components of the lignocarbohydrate complex of the wood, which does not only improve its characteristics but also provides form and size stability in an environment with changeable humidity. A Mettler Toledo DSC 823e/700 differential scanning calorimeter was used to examine the kinetics. Heat fluxes were measured in 30 µl sealed steel crucibles that could sustain steam pressure up to 15 MPa. At a heating rate of 10 °C/min, the heat flow curve showed an exothermic peak with a maximum temperature of 150.7 °C. Aspen wood with 15 % cardanol content has a compressive strength along the fibers of 69 MPa, a volume swelling limit of 2.6 %, and a moisture absorption limit of 18 %. The ultimate water absorption and ultimate volumetric swelling of wood impregnated with cardanol are comparable to the relevant indications of the modified wood brands Accoja, Belmadur, and Thermowood.

Influence of Drying Temperature on Paper Properties Made of Sulfate-Bleached Softwood and Hardwood Pulps
Authors:   Saint-Petersburg State University of Industrial Technologies and Design, Prokhorov Daniil A. , Dubovy Vladimir K.
Published: June 2023

Most paper mills in the Russian Federation consume around 40 % more electrical power than they actually require. The reasons are a low level of technical, scientific, and proficient assistance. Moreover, the produced goods have non-competitive consumption characteristics. The urgent current measures in this matter contain constructional and technological optimization, including drying temperature modes. The drying section of a paper machine is the most energy-consuming, while it significantly affects the mechanical strength and supplementary properties of the resulting paper goods with their structural and dimensional characteristics. Drying the paper web takes 72–77 % of the total energy of the paper machine. Therefore, the purpose of this study is to analyze the influence of the temperatures of the drying process on the strength and structural-dimensional properties of the paper, with the perspective for further application of the results in the practice of industrial companies and additional scientific investigation. The presented results show the influence of pulp type, beating degree, mass of 1 m2, and drying temperature on the strength and structural-dimensional properties of laboratory samples. Within the investigational process, laboratory samples from sulphate-bleached softwood and hardwood pulp were created and tested. The weights of the samples varied from 60 to 120 g/m2, and the beating degrees ranged from 20 to 50 °SR. The drying temperature extended from 80 to 140 °C. The analysis of the acquired paper samples revealed that the drying temperatures had a considerable impact on the strength, structure, and dimensional qualities of the material. Namely, while sulfate-bleached softwood and hardwood pulp types were used as a raw material, increasing the drying temperature from 80 to 140 °C had the greatest effect on the structural-dimensional properties of the paper made from a pulp with a higher beating degree and the greatest effect on the strength properties of the paper made from a pulp with a lower beating degree.

In order to create a valuable gene pool of cedar pines in the conditions of the Komi Republic, rootstock crops of Siberian pine (Pinus sibirica Du Tour) were planted on the territory of laboratory training center of the Syktyvkar Forest Institute. The plants were collected from different areas of the Komi Republic and the Arkhangelsk region for adjustment to the local, northwestern climate. The paper presents the results of the variational analysis of morphological parameters and growth dynamics in P. sibirica cultures. Height, trunk diameter, and crown diameter were chosen as the morphometric criteria. The variability of the studied traits ranged from 18.8 to 93.1 %. The average height of the plants was 72.2±3.9 cm, the average trunk diameter was 2.0±0.1 cm. The most changeable characteristic was the diameter of the crown of the plants, which ranged between 11 and 148 cm with Сv of 30.6–93.1 %. The plants of Yarensk origin were the most developed according to the examined morphometric criteria. The average growth of P. sibirica plants in height within the age group of 9–11 years over three years was 13.5±0.9 cm. The lowest growth rate was registered in plants of the Sysola group (1 cm), whereas plants of Yarensk origin had the highest growth rate (38 cm). Throughout the research period, plants of all groups had a consistent rise in overall height. However, this trait variability was reduced only in the group of plants of Yarensk origin. The maximum variability in all three traits was observed in plants of Syktyvkar origin with Сv of 39.7–93.1 %. In general, high variability in the development of Siberian pines over three years across all experimental groups was detected. The investigation results can be applied for further research on the development and inheritance of economically valuable traits and decorative characteristics of P. sibirica in the conditions of the middle taiga subzone of the Komi Repub lic.

The content of photosynthetic pigments in silver birch leaves (Betula pendula Roth.) is studied in areas with technogenic load and in baseline conditions. The research is performed in a forb type of birch forest in the suburbs of Krasnoyarsk. The wood stands exposed to a high level of technogenic pressure are located to the east of the city in the prevailing direction of air mass movement. The reference stands are under the least technogenic pollution and grow in western and northern areas of the city. The photosynthetic pigments are determined in ethanol extracts, calculated per 1 g of absolute dry mass (a.d.m.) of the leaves. A level of dust deposition on leaf surfaces is evaluated according to the method of J. Detrie (1973). The amounts of zinc, lead, aluminum, and fluorine ions are estimated in the washed leaves. It is found that the content of chlorophyll a inside the birch leaves from a relatively clean environment is slightly lower compared to the concentration in the leaves with the technogenic load. The chlorophyll b concentration is 2.5–3 times less than chlorophyll a and is close to the amount of carotenoids. The total chlorophyll content in birch leaves from different locations ranges from 5.4 to 7.3 mg/g a.d.m., the ratio of chlorophyll forms varies from 2.5 to 3, the proportion of net chlorophyll to carotenoids is between 3.4 and 3.8. As the level of dust increases, the content of the total photosynthetic pigments also rises. The accumulation of zinc ions in the birch leaf cells has a negative effect on pigment content, especially chlorophyll a, but doesn’t correlate with the ratio of the pigments. There has not been any correlation found between the lead and the photosynthetic pigments. It is noted that the rise in the concentration of aluminum significantly affects the contents of the chlorophylls and the carotenoids, while no relationship has been discovered between the concentration of aluminum and the proportion of the pigments. The relationship between fluorine and different forms of chlorophyll is absent as well. The results indicate the adaptive response of the photosynthetic system to the presence of pollutants in concentrations below the threshold values that are indicated in the literature.

The provenance trials of Scots pine (Pinus sylvestris L.) in the Central Russian forest-steppe area were established by M.M. Veresen in 1959. They have become a natural laboratory for genetic and environmental research in order to solve the practical issues of forest seed zoning. The study of the intraspecific diversity of the provenance trials makes it possible to distinguish patterns in the formation of species with various origins under the influence of different ecological, genetic, and climatic conditions. This article presents the results of a multi-year research project. This allows us to state with full responsibility the strong influence of environmental and genetic factors on the characteristics of growth, resistance, trunk productivity, and reproductive capacity of Scots pine in new growing conditions. The generative parts of the study objects were also examined by morphometric indicators. The changes were revealed in seed production, size, cone coloring, color and weight of 1000 pieces of seeds, seed release, seed fullness, germinative energy, and absolute germination. Genetic factors, which are programmed by ancestry, define the constancy of the difference in size and color of cones and seeds. In addition, genetic factors, along with the weather conditions of a new location, regulate reproductive ability. It was noted that Scots pine with different geographical origins enters the flowering phase at different times. The northern trees are 5–7 days earlier than locals; the southern trees are 5 days later. They were studied in the climate of the Voronezh region. The variability in the characteristics of the generative organs of Scots pine is also affected by its place of birth. The size and weight of the cone are directly related to the geographic latitude. The length and weight of the cone increase with movement from north to south. There is no strict relationship between the release of the seeds during free pollination and the place of origin since the study objects were surrounded by various pollinators. The weight of 1000 seeds changes with the same regularity as in natural stands of pine: it increases with the geographical latitude of the origin. Consequently, under the influence of new growing conditions, Scots pine is strongly affected by its genetic factors that determine the stability, trunk productivity, and reproductive capacity of the species.

Published: June 2023

AbstractBackground: Spinal anaesthesia is the most preferred regional anaesthesia technique as it is easy to perform,economical and produces rapid onset of anaesthesia and complete muscle relaxation. The aim of intrathecal localanaesthetic is to provide adequate sensory and motor block necessary for all infra umbilical surgeries.Aims and Objectives: The aim of the study is to compare the Onset and Duration of Sensory Block; Onset andDuration of Motor Block and other factors in two groups i.e., Hyperbaric Bupivacaine 0.5% with Clonidine 30μg&Hyperbaric Bupivacaine 0.5% with Magnesium sulphate 50 mg when given intrathecally.Materials and Methods: A Comparative three group randomized clinical study with 90 patients with 30 patientsin Group C (Clonidine), 30 patients in Group M (Magnesium) and 30 patients in Group N (Normal saline) to studythe onset of motor and sensory block, changes in hemodynamics and side effects.Results: Our study has demonstrated that Intrathecal clonidine (30 mcg) prolonged post-operative analgesia alongwith earlier onset and prolonged duration of sensory and motor blockade compared to both magnesium (50 mg)and control.Intrathecal magnesium (50 mg) also increased the analgesic duration compared to control but it wasassociated with delayed onset of both sensory and motor blockade compared to both clonidine and control.Conclusion: Clonidine can be a good alternative adjuvant with 0.5% hyperbaric bupivacaine when comparedto others like fentanyl, magnesium, midazolam, ketamine etc. as it provides early onset of sensory and motorblockade and also prolonged duration of post-operative analgesia.

AbstractBackground and objectives: The exact course of SARS -2(COVID-19) and its complications on multiorgan systemare complex and still under studies. Musculoskeletal system has also been affected post covid in various forms.This study was taken up to analyse the effects of covid-19 disease on the hip bone and join tissue.Materials and Methods: Retrospective analysis of ten patients was done who had been hospitalised with covid-19infection and later complained of hip pain. They underwent MR imaging and were found to have degenerativechanges characterizing with avascular necrosis (AVN) of head of femur .One of them had history of previoussurgery of femur with PFN, doin well but developed AVN after covid.Results: Observation of this group showed a clear correlation among the history of COVID-19 disease in thepatients, moderately severe symptoms, high levels of IgG antibodies, and the time of occurrence of joint changes.No other risk factors for AVN or auto-immune or degenerative diseases were found in the study group. The groupof patients responded well to empirical treatment with anti-inflammatory drugs ans supportive therapy, whichsubsided acute inflammatory symptoms and pain in the joints.Conclusions: It is concluded that there have been obvious musculoskeletal complications in covid patientsincluding AVN which could be attributed to the high use steroids and microembolism leading to bone necrosis.Hence more studies and long follow-up is suggested.

Published: June 2023

Although nitrocyclopropanedicarboxylic acid esters are widely used in organic syntheses, nitrocyclopropanes with an acyl group have not yet been synthesized. When adducts of β-nitrostyrene and 1,3-dicarbonyl compounds are treated with (diacetoxyiodo)benzene and tetrabutylammonium iodide, iodination occurs at the α-position of the nitro group, and the subsequent O-attack of the enol moiety leads to 2,3-dihydrofuran. Cyclopropane was successfully synthesized through C-attack as the acyl group became bulkier. The obtained nitrocyclopropane was transformed into furan upon treatment with tin(II) chloride via a ring-opening/ring-closure process.
