A record of Botrychium lanceolatum (S. G. Gmel.) Ångstr., a new species for the flora of the middle zone of European Russia from Kostroma Region

The article reports on a find of a new plant native to the flora of central European Russia – Botrychium lanceolatum (S. G. Gmel.) Ångstr., which was discovered during a survey of a 60-year-old clearcut in the course of floristic work on the territory of M. G. Sinitsyn “Kologrivskiy Les” State Nature Reserve (the Kostroma Region). Collection and determination were carried out by the author of the article I. G. Krinitsyn. For the Kostroma Region, the species was not indicated in any floristic checklist. Herbarium specimens of the aboveground part of the sporophyte are kept in the Herbarium of the Kostroma State University and the “Kologrivskiy Les” State Nature Reserve Herbarium, as well as transferred to the Herbarium of the Altai State University (ALTB). B. lanceolatum is a relict species of the forest zone of the Holarctic with a fragmented range mainly in the subarctic, northern temperate zone and in the mountains of the warm temperate zone of Eurasia and North America. In Russia, it is sporadically found in the forest zone from the Murmansk and Leningrad Regions to Kamchatka and Sakhalin, inclusively; it enters the Arctic on the Chukchi Peninsula. The species is rare throughout its range; the populations are represented by single individuals. It is included in many regional Red Data Books of the Russian Federation. B. lanceolatum became the fifth species of the Botrychiaceae Nakai family in the pteridoflora of the Kostroma Region (and the middle zone of European Russia as a whole). In the Kostroma Region, the species is located on the extreme southern border of the range in the middle zone of the European part of Russia. The population of B. lanceolatum at the time of the discovery was represented by 4 individuals in different ontogenetic states. The data on the new location and phytocenotic conditions of growth of the species are given; a brief morphological description and information on the dynamics of the population are presented.

Effect of Genetic / Environmental Influence on Growth of Newborn in Himachal Pradesh

Introduction: The effects of altitudinal variation on child growth and development have long been a center of attention for researcher. We believe that hereditary factor primarily affects on child growth and development however environment has secondary effect on it. The available literature on newborns in Himachal Pradesh establishes the fact that as altitude increases the crown heel length decreases. A comprehensive significant finding was also available in both the regions of Himachal Pradesh in terms of head length, foot length, nasal height etc. the comparison between the neonates of the two zones of Himachal Pradesh explains the difference in physical appearance of people of both zones. These features may be biological or behavioral in nature, genetic or developmental in origin. Most instances, a combination of factors are involved. Methods: The present study included 185 parents and their newborns from two zones (Lower zone and Middle zone) of Himachal Pradesh and separated as per the criteria. Measurement of newborn parameters was taken in 12-24 hours after birth by using digital vernier caliper. Ethical clearance from university and permission from Himachal Pradesh government was taken. All the newborns were separated as per criteria 1. Mother / Father from Lower Zone. (Zone category 1) 2. Mother / Father from Middle Zone. (Zone category 2) 3. Mother from Lower Zone / Father from Middle Zone. (Zone category 3) 4. Mother from Middle Zone / Father from Lower Zone. (Zone category 4) Results: Statistically significant difference was obtained in all the four categories. Different parameters were compared across different parent- zone categories by one way ANOVA. The results showed that four parameters shows significantly across groups, viz, Weight, Facial Length, Nasal Height and Philtrum width in all the Zone categories. Conclusions: The early historical studies mention that people living in Himachal Pradesh have migrated from different geographical locations hence their genetics, as well as culture is different from each other. This study clearly demonstrates the effects of environmental factors on child growth and development in Himachal Pradesh. KEY WORD: Anthropometry, Newborn, Himachal, Environment, Genetics.

Crab diversity as support for ecotourism activities in Pejarakan Mangrove Forest, Buleleng, Bali, Indonesia

Ginantra IK, Muksin IK, Joni M. 2021. Crab diversity as support for ecotourism activities in Pejarakan Mangrove Forest, Buleleng, Bali, Indonesia. Biodiversitas 22: 4139-4145. This research aims to determine the diversity of crabs to support ecotourism activities in the coastal mangrove forest of Pejarakan Buleleng. Sampling of crabs was carried out using the square method, as many as 23 squares were spread over three mangrove zones, namely the front zone, the middle zone, and the rear zone. The number of individual crustacean species in each square plot was counted. Crab identification is based on morphological characters (shell color, claw shape, body-color, body size). Habitat use activities are observed directly. The diversity of crabs was calculated using the Shannon-Wiener diversity index. The results showed that in the coastal mangrove area of Pejarakan Buleleng, there were 11 species of crabs (9 species of crabs and 2 species of hermit crabs). Species diversity is in the medium category (index 2.25) and evenness index is high (E = 0.93, mangrove conditions are stable). The seaward mangrove zone shows a higher diversity of crab species than the middle zone and the rear zone. The species of crabs that are quite abundant in the three zonings are Uca vocans, Chiromanthes sp., and Coenobita sp. Characteristics of crabs, activities, habitat use in mangrove zoning are attractions for ecotourism activities.

Airfoil optimization for small horizontal axis wind turbine

In order to take advantage of the low wind speed found in the Colombian territory, a gradient-based optimization process (GBA) of 2 airfoils is carried out, using the Xfoil software to evaluate the interactions. The shapes chosen will be destined for the root and for the middle zone of a blade for a small horizontal axis wind turbine (sHAWT). The blade will be created from the calculation of the chord and pitch angle with the blade element momentum methodology (BEM) and the SHAWT will be tested by CFD software to check its performance. As a preliminary result, a root-bound airfoil has been obtained with a higher performance than the airfoil used as a bases.

Formation of the Astilbe Buch.-Ham collection in a continental climate

The paper analyzes the dynamics of formation of a collection of Astilbe varieties and species included in the bioresource collection USU 44053 in the conditions of Western Siberia forest-steppe. The ways of further expansion of Astilbe collection fund are substantiated by attracting representatives of the Astilbe chinensis , A. crispa groups; varieties with rhombic, narrow-lobed and pyramidal inflorescences, primarily belonging to the group of colors: red, dark red, purple and dark purple. In contrast to the conditions of the middle zone of Russia in which Astilbe are divided into four groups according to the period of flowering: 1) very early (end of June - July), 2) early (July), 3) medium (mid-July - mid-August) and 4) late (end of August - mid-September), for the conditions of Western Siberia forest-steppe, with intense heat gain in mid-May-early June, the flowering dates of very early and early varieties converge. Accordingly, there are three groups: early-flowering (bloom July 8-10), medium-flowering (bloom from July 15-18), late-flowering (bloom from late July-early August). It is proposed to add a narrow-lobed and pyramidal-drooping inflorescence to the traditionally described forms of Astilbe varieties. The expansion of the set of dwarf varieties from the A. crispa group with strongly dissected fringed leaves gives additional opportunities for a landscape design.

Chest X-Rays Findings in Patients Positive for COVID 19 at Sheikh Zayed Hospital Lahore

Aim: To assess the results of chest x ray radiographs of patients positive for Covid-19, presented at the tertiary care hospital according to the classification by the British Society of Thoracic Imaging (BSTI. Place and Duration: In COVID-19 Ward (Department of Medicine) Sheikh Zayed Hospital, Lahore for three months duration from January 2021 to March 2021. Methods: A total of 96 patients were selected. In this observational study, positive COVID-19 patient determined by the reverse transcriptase polymerase chain reaction (RT-PCR) were enrolled for this study above the age of 14 years. CXR results were classified conferring to BSTI documentation and classification in terms of percentage and frequency. Results: Chest rays of 96 patients who tested positive for Covid-19 by RT-PCR over the age of 14 years were examined. Chest X-rays are classified according to the BSTI Covid-19 X-ray classification. Out of 96 patients, 10 patients (10.41%) had normal chest x-rays, 19 (19.80%) patients had classic bilateral, peripheral and basal consolidation / ground glass opacity (GMO), 60 (62.5%) had unspecified group,7(7.29%) patients have poor quality X-ray film. The unilateral involvement was noticed in 15 and bilateral in 49 patients, 12 of the patients had diffuse involvement on chest radiograph and peripheral involvement in 39 patients. According to regional dominance, 41 of the unspecified (42.70%) had middle and lower lung involvement, 7 (7.29%) had only the middle zone, and 8 (8.33%) had involvement of lower zone. Conclusions: In this study, Covid-19 chest X-rays are usually presented as ground glass opacity, mixed consolidation with GGOs in the middle and lower peripheral areas of the bilateral lung. Chest X-ray BSTI classification is used to classify Covid-19 severity in our patients, thus differentiating in the classic Covid-19 of the middle zone versus low zone involvement.

Intermittent Fasting with a High Protein Diet Mitigated Osteoarthritis Symptoms by Increasing Lean Body Mass and Reducing Inflammation in Osteoarthritic rats with Alzheimer’s Disease-Like Dementia

Menopausal women are susceptible to osteoarthritis and memory impairment. We hypothesized that Alzheimer’s-like disease (AD) exacerbates osteoarthritis and that intermittent fasting(IMF) with a high-protein(H-P) diet would enhance memory function and relieve osteoarthritis symptoms in estrogen-deficient animals with surgically induced AD and osteoarthritis. The action mechanism was also explored. Ovariectomized Sprague-Dawley rats were fed high-fat(H-F) or H-P diets for two weeks, and then they had a hippocampal infusion of β-amyloid(25-35) for 4 weeks to induce AD and an injection of monoidoacetate(MIA) into the articular cartilage to induce osteoarthritis. Four groups had AD symptoms, whereas two groups had non-AD symptoms by hippocampal amyloid-β(35-25) infusion. All rats had an MIA injection into the articular cartilage of the left knee. IMF suppressed memory impairment in AD rats, especially those fed H-P diets. Compared to Non-AD, AD exacerbated osteoarthritis symptoms, including swelling, limping, slowed treadmill running speed, and uneven weight distribution in the left leg. The exacerbations were linked to increased inflammation and pain, but IMF and H-P lessened inflammation and pain-related symptoms. Lean body mass(LBM) also decreased with AD and IMF, but H-P protected against LBM loss. Histological examination of the knee joint revealed the degree of the cellular invasion into the middle zone, and the changes in the tidemark plateau were greatest in the AD-AL with H-F, while non-AD-IMF improved the cellular invasion to as much as non-AD-AL. H-P reduced the infiltration into the middle-zone of the knee and promoted collagen production. In conclusion, AD exacerbated the articular cartilage deterioration and memory impairment, and IMF with H-P alleviated the memory impairment and osteoarthritic symptoms by decreasing hippocampal amyloid-β deposition and proinflammatory cytokine expressions and by increasing LBM.
