Abstract. The Canary Island Long-Baseline Observatory (CILBO) is a double station meteor camera setup located on the Canary Islands and operated by ESA’s Meteor Research Group since 2010. Observations of meteors are obtained in the visual wavelength band by intensified video cameras from both stations, supplemented by an intensified video camera mounted with a spectral grating at one of the locations. The cameras observe during cloudless and precipitation-free nights and data are transferred to a main computer located at ESA/ESTEC once a day. The image frames that contain spectral information are calibrated, corrected, and finally processed into line intensity profiles. An ablation simulation, based on Bayesian statistics using a Markov-Chain Monte-Carlo method, allows to determine a parameter space, including the ablation temperatures, chemical elements and their corresponding line intensities, to fit against the line intensity profiles of the observed meteor spectra. The algorithm is presented in this paper and one example is discussed. Several hundred spectra have been processed and made available through the Guest Archive Facility of the Planetary Science Archive of ESA. The data format and meta-data are explained.

Abstract. Biome reconstructions are commonly used in data-data and data-model comparison studies to understand past vegetation dynamics. However, most of these assessments are based on the direct comparison of dominant biomes inferred from pollen samples or vegetation simulations. Dominant biomes are deduced from pollen samples using biome affinity scores, which aggregate pollen percentages of taxa assigned to the different biomes. While this approach generates good results over a large range of temporal and spatial scales, reducing pollen assemblages to a single dominant biome can substantially simplify the vegetation signal preserved in pollen samples and even bias conclusions when, for instance, minimal changes in pollen percentages can change the inferred dominant biome. To resolve these issues, we propose to use the Earth Movers’ distance (EMD) as a new metric to compare distributions of biome scores. The EMD has two main advantages: 1) the distributions of biome scores do not need to be reduced to their dominant biome, and the full breadth of the data is taken into account, and 2) different weights can be given to different types of disagreements to account for the ecological distance (e.g. reconstructing a temperate forest instead of a boreal forest is ecologically less wrong than reconstructing the temperate forest instead of a desert). We also introduce EMD-based statistical tests that determine if the similarity of two samples is significantly better than a random association. This paper illustrates the use of the EMD across a series of palaeoecological data-data and data-model case studies based on published data and simulations. These applications highlight the diverse types of analysis where the EMD adds value compared to analyses of the dominant biomes only. The EMD and the statistical tests are included in the paleotools R package (https://github.com/mchevalier2/paleotools).
Identification of thermal signature and quantification of charcoal in soil using differential scanning calorimetry and benzene polycarboxylic acid (BPCA) markers
Authors: Hardy Brieuc , Borchard Nils , Leifeld Jens
Published: July 2022

Abstract. Black carbon (BC) plays an important role in terrestrial
carbon storage and can sustainably improve soil fertility. However, the
accurate quantification of BC remains critical to fully unravelling the
functions and dynamics of BC in soil. In this study, we explored the
potential of differential scanning calorimetry (DSC) to identify,
characterize and quantify charcoal in the soil of pre-industrial charcoal
kiln sites from various forest and cropland areas in Belgium and Germany.
Pre-industrial charcoals and uncharred soil organic matter (SOM)
demonstrated a distinct thermal signature that could be used to distinguish
between them, with charcoal being more thermally stable than SOM. The DSC
pattern of charcoals was characterized by one to three specific exothermic peaks,
varying in size and position depending on soil conditions. Our data suggest
that the thermal moieties within charcoal depend on the strength of chemical
bonds of C atoms (increasing with the degree of aromatic condensation and
decreasing with weathering) and on the activation energy required to
initiate combustion. Despite the specific thermal features of charcoal, its
decomposition spans a wide range of temperatures that overlaps with the
thermal signature of uncharred SOM. This stresses the challenge of BC
quantification in soil and hinders the use of cut-off temperatures to
accurately quantify charcoal in soil. Therefore, charcoal-C content was
estimated from the relative height of exothermic peaks, attributed either to the
combustion of charcoal or SOM. For a selection of 45 soil samples,
charcoal-C content estimated by DSC was compared to benzene polycarboxylic
acid (BPCA) abundance, a widely used method to quantify BC in soil. The two
methods correlated strongly (R2=0.97), with BPCA C
representing about one-fifth of DSC-derived charcoal C. This reinforces the
view that operationally defined BC content has an absolute quantitative
value only if the recovery rate is controlled, which is very complicated for
many case studies. Overall, our results demonstrate that dynamic thermal
analysis is largely under-exploited despite providing quantitatively
interpretable information across the continuum of SOM.
Modeling enhanced firn densification due to strain softening
Authors: Oraschewski Falk M. , Grinsted Aslak
Published: July 2022

Abstract. In the accumulation zone of glaciers and ice sheets snow is transformed into glacial ice by firn densification. Classically, this process is assumed to solely depend on temperature and overburden pressure, which is controlled by the accumulation rate. However, exceptionally thin firn layers have been observed in the high-strain shear margins of ice streams. Previously, it has been proposed that this firn thinning can be explained by an enhancement of firn densification due to the effect of strain softening inherent to power-law creep. This hypothesis has not been validated, and the greater firn densities in the presence of horizontal strain rates have not yet been reproduced by models. Here, we develop a model that corrects the firn densification rate predicted by classical, climate-forced models for the effect of strain softening. With the model it is confirmed that strain softening dominates the firn densification process when high strain rates are present. Firn densities along a cross section of the Northeast Greenland Ice Stream (NEGIS) are reproduced with good agreement, validating the accuracy of the developed model. Finally, it is shown that strain softening has significant implications for ice core dating and that it considerably affects the firn properties over wide areas of the polar ice sheet, even at low strain rates. Therefore, we suggest that, besides temperature and accumulation rate, horizontal strain rates should generally be considered as a forcing parameter in firn densification modeling.
Impact of icebergs on the seasonal submarine melt of Sermeq Kujalleq
Authors: Kajanto Karita , Straneo Fiammetta , Nisancioglu Kerim
Published: July 2022

Abstract. The role of icebergs in narrow fjords hosting marine terminating glaciers in Greenland is poorly understood, even though icebergs provide a substantial freshwater flux that can exceed the subglacial discharge. Iceberg melt is distributed at depth, contributing to fjord stratification, thus impacting melt and dynamics of the glacier front. We model the high-silled Ilulissat Icefjord in Western Greenland with the MITgcm ocean model, using the IceBerg package to study the effect of icebergs on fjord properties, and compare our results with available observations from 2014. We find the subglacial discharge plume to be the primary driver of the seasonality of circulation, glacier melt and iceberg melt. Icebergs are necessary to include to correctly understand the properties of Ilulissat Icefjord, since they modify the fjord in three main ways: First, icebergs cool and freshen the water column within their vertical extent; Second, icebergs depress the neutral buoyancy depth of the plume and the outflow route of glacially modified water; Third, icebergs modify the deep basin, below their vertical extent, due to both increased entrainment of glacially modified water into the fjord, and iceberg modification of the incoming ambient water. Furthermore, the depressed neutral buoyancy depth of the plume limits melt to the deep section of the front of Sermeq Kujalleq (Jakobshavn Isbræ) even during peak summer, and thus promotes undercutting. We postulate that the impact of icebergs on the neutral buoyancy depth of the plume is a key mechanism connecting iceberg melange and glacier calving, independent of mechanical support.
Benefits and challenges of dynamic sea ice for weather forecasts

Published: July 2022

Abstract. The drive to develop environmental prediction systems that are seamless across both weather and climate timescales has culminated in the development
and use of Earth system models, which include a coupled representation of the atmosphere, land, ocean and sea ice, for medium-range weather forecasts. One region where such a coupled Earth
system approach has the potential to significantly influence the skill of weather forecasts is in the polar and sub-polar seas, where fluxes of
heat, moisture and momentum are strongly influenced by the position of the sea ice edge. In this study we demonstrate that using a dynamically
coupled ocean and sea ice model in the European Centre for Medium-Range Weather Forecasts (ECMWF) Integrated Forecasting System results in improved sea ice edge position forecasts in the Northern
Hemisphere in the medium range. Further, this improves forecasts of boundary layer temperature and humidity downstream of the sea ice edge in some
regions during periods of rapid change in the sea ice, compared to forecasts in which the sea surface temperature anomalies and sea ice
concentration do not evolve throughout the forecasts. However, challenges remain, such as large errors in the position of the ice edge in the ocean
analysis used to initialise the ocean component of the coupled system, which has an error of approximately 50 % of the total forecast error at
day 9, suggesting there is much skill to be gained by improving the ocean analysis at and around the sea ice edge. The importance of the choice of
sea ice analysis for verification is also highlighted, with a call for more guidance on the suitability of satellite sea ice products to verify
forecasts on daily to weekly timescales and on meso-scales (< 500 km).
The influence of IGF-I and Emdogain on the behavior of dental epithelial cells in a three-dimensional scaffold model
Authors: Heezen Maria Johanna Jacoba , Zhang Weibo , Rudolph Sara , Walboomers X. Frank , Yelick Pamela C.
Published: July 2022

Aim: Tooth decay and associated periodontal disease remain the most common chronic diseases in current society. In the future, individually tailored, more effective therapeutic treatment options could be provided through the application of tissue engineering and regenerative medicine and dentistry (TERMD) approaches. A relevant finding is the potential of both dental mesenchymal and dental epithelial cells to regenerate mineralized dentin and enamel tissues, respectively.Materials and Methods: In the current study, a multi-layered, bioengineered tooth bud model was assembled by combining human dental mesenchymal (hDM) and porcine dental epithelial cells (pDE). The hDM cells were seeded onto poly(epsilon-caprolactone)/ poly (lactide-co-glycolide) (PCL/PLGA) wet electro-spun scaffolds overlayed with confluent pDE cell sheet harvested from thermo-reversible tissue culture plates. The so-formed multi-layered bioengineered tooth bud was then used to study the mineralization potential of the dental cells in in vitro culture. It was hypothesized that the addition of the in media soluble factors Insulin-like growth factor 1 (IGF-I) and the extracellular matrix derivate Emdogain (EMD) would result in enhanced differentiation and mineralized dental tissue formation. Scanning Electron morphological observation was used to characterize scaffolds porosity. Histological and immunofluorescent analyses confirmed the localization of hDM cells inside the scaffold, an intact pDE cell sheet, and the presence of beta-integrin 1-positive cell-cell junctions connecting the two.Results: Scanning Electron Microscopy showed that EMD, in particular, enhanced the mineralization potential of pDE cells. qRT-PCR analyses showed that both EMD and IGF-1 significantly enhanced the expression of Ameloblastin (AMBN), reflecting pDE cell differentiation.Conclusion: In conclusion, these results proved the hypothesis that both EMD and IGF-1 should be considered for their utility in preclinical dental tissue engineering approaches.
PORTUGUÊS COMO LÍNGUA DE ACOLHIMENTO PELAS VOZES DE MIGRANTES DE CRISE
Authors: Cursino Carla Alessandra
Published: July 2022

O objetivo deste artigo é propor reflexões sobre o conceito e as práticas didáticas de Português como Língua de Acolhimento (PLAc), subárea do Português como Língua Adicional (PLA) dedicada ao ensino-aprendizagem de português para migrantes de crise (CLOCHARD, 2007). Estudos recentes realizados por autoras brasileiras/autores brasileiros questionam a noção original de PLAc veiculada em Portugal por Ançã (2008), Grosso (2010), entre outras. Teóricas/teóricos do Brasil apontam o caráter neocolonizador (DINIZ, 2015) e assimilacionista (ANUNCIAÇÃO, 2017; 2018) da acepção portuguesa de PLAc, que alça o idioma português à condição fundamental para o êxito da comunidade migrante no território de acolhida, silenciando sua bagagem linguística, cultural e epistêmica em nome de uma pretensa integração social. Face a tais questões, conversei com 6 migrantes, de diferentes nacionalidades e trajetórias migratórias, a fim de compreender suas percepções sobre o ensino da língua portuguesa, no Brasil, em contexto migratório. Neste diálogo, percebo que, para o indivíduo migrante, tão importante quanto conhecer o idioma local - que lhe facilita o trânsito social - é a mobilização de suas línguas, culturas e conhecimentos na sala de aula de PLAc e para além dela, em verdadeiras ações de linguajamento (MATURANA, 1990; VERONELLI, 2019; MIGNOLO, 2020).

ANÁLISE DO NARRADOR DE AMOR DE PERDIÇÃO, DE CAMILO CASTELO BRANCO
Authors: Amaral João Pedro Wizniewsky
Published: July 2022

Este artigo propõe uma análise sobre o narrador de Amor de Perdição, uma das obras mais importantes do escritor português Camilo Castelo Branco e do movimento do Romantismo em Portugal. Esta análise foi realizada por meio de uma leitura atenta do romance, considerando algumas características do Romantismo, apontadas por Carlos Reis (1999), Antonio Candido (2000), György Lukács (2000) e Theodor Adorno (2003), estudos sobre o narrador (BENJAMIN, 1983). A análise indica que o narrador de Amor de Perdição mostra-se complexo, autoconsciente dos problemas de seu tempo e irônico, além de tentar romper limites ficcionais. Ou seja, um narrador típico do Romantismo que ajuda a consolidar o romance enquanto gênero literário. Ainda, o narrador apresenta uma consciência de que a narrativa é apenas um recorte, valorizando a experiência e a subjetividade, indo, assim, contra as tendências clássicas.
UM CAVALO NA MINHA PAISAGEM: O SUJEITO LÍRICO QUE SE DESLOCA PARA A MORTE DO OUTRO
Authors: Ribeiro Gonçalves Iverton Gessé
Published: July 2022

O presente trabalho se debruça sobre o estudo da paisagem na poesia de Cecília Meireles, em específico, a experiência de morte que afeta o sujeito lírico no poema O Cavalo Morto (1983). A paisagem construída pelo sujeito lírico e que, mutuamente, o constitui como ser tocado pela morte será analisada com base nos princípios teóricos do poeta e pesquisador francês Michel Collot, acionando as noções que perpassam a estrutura de horizonte, o sujeito lírico fora de si e o referente poético. Para que o sujeito experiencie a morte na morte de outro é necessário um deslocamento de seu lugar na paisagem em direção ao horizonte, podendo, em curtos golpes de vista, transcender essa estrutura. Esse estudo parte de uma perspectiva em que o sujeito poeta participa da experiência de morte na constituição da paisagem literária, portanto, considera o objeto literário como uma produção poética do eu em que sujeito e paisagem se constituem mutuamente.
Практика православного крещения в СССР в зеркале статистики и оценках исследователей 1940-х – 1970-х гг.
Authors: Апанасенок Александр Вячеславович , Пудякова Ирина Сергеевна
Published: July 2022

Работа посвящена истории практики православного крещения в СССР 1940-х – 1970-х гг. Авторы исследуют статистику совершения этого таинства на протяжении трех послевоенных десятилетий, анализируют вопрос о достоверности соответствующих количественных данных, а также рассматривают социальный состав и мотивы людей, обращавшихся к священнослужителям с целью крещения своих детей. В статье показано, что в течение всего изучаемого периода обряд крещения оставался культурной нормой для большей части граждан в традиционно-православных регионах СССР, а статистика далеко не отражала его реальных масштабов. Важнейшими факторами сохранения практики крещения детей выступали религиозность старших поколений советских граждан, а также стремление родителей к соблюдению древней традиции.

Published: July 2022

Проведено исследование почв, развитых на засоленных плиоценовых отложениях акчагыльского яруса в аридной зоне Восточного Предкавказья (Республика Дагестан). Цель исследования заключалась в анализе влияния выпаса скота на химические свойства и биологическую активность почв на разных элементах рельефа. Изучены основные химические свойства каштановых почв и солонцов в различных геоморфологических условиях и разной интенсивности пастбищной нагрузки. Впервые получены данные о биологической активности почв зимних пастбищ в пределах теплой непромерзающей почвенно-климатической фации. Показано, что во всех случаях отмечаются весьма высокие значения коэффициента микробного дыхания, что указывает на стрессовое состояние микробного сообщества. Учитывая сенсорность и чувствительность микробного сообщества к изменениям внешних условий, такой подход может быть эффективным при экологической оценке состояния и прогнозов развития почв.

Published: July 2022

Геотектоническая активность элементов земной коры формирует эколого-геохимические аномалии различного качественного и количественного характера. Как правило, в пределах платформенных областей тектоническая активность проявляется в виде разломной тектоники. Участки разломных зон являются путями проникновения на поверхность комплекса металлов и неметаллоидов глубинного происхождения. Их концентрирование в подземных водах формирует патогенные экологические эффекты. Целью настоящей работы является изучение эколого-гидрогеохимических особенностей подземных вод, которые приурочены к зонам активной геотектонической деятельности в пределах Липецкого горнопромышленного района. Представлен анализ основных неотектонических структур, даны пространственные характеристики разломных зон, их место в рельефе и особенности геологического строения. Значимость данных исследований определена дифференцированием загрязнений подземных вод природного и техногенного характера, формирующегося в пределах зон влияния объектов горнодобывающей деятельности. Методика исследований включала комплекс предполевых работ по выделению зон активной тектонической деятельности. Она базировалась на схеме неотектонических структур Липецкой области. Бор обозначен как маркирующий элемент, характеризующийся исключительно природным происхождением. Пробоотбор подземных вод неоген-четвертичного и девонского водоносных комплексов осуществлялся в пределах выделенных зон. Результаты исследований систематизированы в формате геоинформационной модели эколого-гидрогеохимических аномалий бора на территории Липецкой области. Выявлена их приуроченность к осевым линиям областей динамического влияния разломов фундамента, линеаментам. Помимо повышенных концентраций бора (до 15 ПДК), в подземных водах отмечены значительные превышения по лантану (до 1000 ПДК), бериллию (до 300 ПДК), титану (до 10 ПДК). Выявлены максимальные превышения для девонских водоносных комплексов. При анализе зон влияния горнодобывающей деятельности наличие бора и вышеперечисленных элементов является маркирующим комплексом природного происхождения.

Оптимизация учета источников загрязнения атмосферного воздуха при нормировании выбросов автозаправочных станций
Authors: Боровлев Андрей Эдуардович , Колосова Ирина Владимировна , Никулина Анна Сергеевна
Published: July 2022

Автозаправочные станции оказывают воздействие на окружающую среду в результате испарения нефтепродуктов в процессе их приемки, хранения, отпуска и очистки резервуаров. При нормировании выбросов автозаправочной станции максимальный выброс (г/с) обычно рассчитывается только для операции закачки нефтепродукта в резервуары. Расчетным путем доказано, что однозначный выбор источника выбросов в пользу операции закачки нефтепродукта в резервуары при расчете максимально разового выброса является ошибочным. На основе анализа результатов вариантных расчетов рассеивания выбросов загрязняющих веществ в атмосферном воздухе установлено, что выбор результирующего источника выбросов зависит от количества одновременно работающих топливно-раздаточных колонок автозаправочной станции. Для дизельного топлива загрязнение атмосферного воздуха в некоторых направлениях будет более опасным при заправке баков автомобилей, чем от закачки топлива в резервуары уже при двух одновременно работающих колонках, а для неэтилированного бензина – при трех колонках. Указанный критерий выбора результирующего источника выброса паров нефтепродуктов автозаправочной станции предложено использовать при проведении работ по установлению нормативов предельно допустимых выбросов и сводных расчетов загрязнения атмосферного воздуха.

Background and Aim: Soft tissue augmentation by fat injections has become the most commonly done cosmetic procedure in the early years. It is being widely used for the improvement of the nasolabial folds. The present study was done to evaluate patient satisfaction after fate injections. Materials and Methods: The prospective and randomized controlled trial study was conducted on 524 consenting patients. Fate injection (2.5 ml) on each groove was injected under a local block with lidocaine 2% added epinephrine 1/300000. Patient satisfaction was evaluated at 14, 21, 45, and 90 days. A photographic record was maintained. Any side effects experienced by the patients were recorded. Results: All the patients were satisfied after two weeks, and more than 80% were happy with this. The majority of the patients were happy at 21 days, and the satisfaction was maintained at 90 months. Conclusion: Fat is a very safe and effective modality and also rarely complication for improving the nasolabial fold. This could prove to be a very useful tool for fate atrophy in the nasolabial fold. The patient's expectations after the procedure are very good or well satisfied and happy.
Restoration Treatment for Female Patients with Non-Bearing Pregnancy at the Early Terms of Gestatione
Authors: Anatolyevich Bugaevsky Konstantin
Published: July 2022

An important indicator of reproductive health is pregnancy failure, which has no decreasing trend worldwide [1-3]. Despite certain successes achieved in treatment and rehabilitation, the problem of pregnancy failure, especially in early gestation, is still urgent [4-6]. Thus, according to different authors, it ranges from 2 to 55%, reaching up to 80% in the first trimester. Statistically, 15 to 25% of all registered pregnancies are spontaneously miscarried, and 80% of pregnancies are terminated before 12 weeks of gestation. The incidence of spontaneous miscarriage remains consistently high, at 45-88.6% of early spontaneous miscarriages. Direct reproductive losses from non-pregnancy in Ukraine amount to 36-40 thousand unwanted children annually. It has been established that the state of reproductive health depends to a greater extent on the duration of pregnancy failure and the complex of rehabilitation measures [1-3]. When a pregnancy occurs within the first 6 months, after a previous miscarriage, a large number of repeated pregnancy losses have been noted. The rate of pregnancy loss after a single miscarriage is 13-17%, after two miscarriages 36-38%, and with recurrent miscarriage up to 45% [1-3]. After spontaneous abortion it is necessary to rehabilitate a woman's reproductive health regardless of the number of spontaneous miscarriages, taking into account all the causes and conditions that contribute to spontaneous pregnancy termination. The principles of the reproductive health rehabilitation program for women after spontaneous miscarriage include the earliest possible initiation of treatment and rehabilitation measures, the principle of an individual approach to rehabilitation measures for each patient [4-6]. The principle of dynamic control over the effectiveness of rehabilitation and therapeutic measures and the principle of continuity between inpatient, outpatient, and sanatoriumresort units of rehabilitation measures are important when using the methods and means of physical rehabilitation [4-7].

Objective: Aim of current study is to examine patients of major thalassemia and determine prevalence of diabetes mellitus among these cases. Study Design: Cross-sectional Place and Duration: DHQ Teaching Hospital Sargodha.Dec 2020-May 2021 Methods: Total 200 hundred patients of major thalassemia with ages 15-45 years were included. After obtaining written consent from the patient, demographic information such as age, sex, and body mass index were gathered. Fasting blood samples were used to estimate the FBS. Medical records were used to collect clinical and laboratory data, such as counts of red blood cells, Hb levels before transfusion, and five-year ferritin levels. Chi-square, student t-tests, and logistic regressions were used for statistical analysis. The whole set of data was analysed with SPSS 24.0. Results: In major thalassemia patients majority of the cases were females 120 (60%) and 80 (40%) were total males. Mean age of the patients was 21.6±8.23 years and had mean BMI 20.5±9.19 kg/m2. Frequency of DM among major thalassemia cases were 18 (9%). Mean five year ferritin among cases was 5214.3±2531 ng/ml. Among 18 cases of DM most of the patients were males 12 (66.7%) and 6 (33.3%) were females. Patients with ages >25 years and ferritin value >6000 ng/ml had increased risk of DM. Mean blood transfusion in DM patients was 2.9±3.66 U/mo with mean duration 15.8±4.17 years. Conclusion: We found from this study that the prevalence of diabetes in major thalassemia patients was 9 percent, with the majority of cases being male. We believe this is attributable to older age, a higher mean five-year ferritin level, and a greater amount of blood transfused.

Plantations of Schizolobium parahybum (pachaco) in the Ecuadorian Humid Tropics are being affected by the disease “decay and descending death”, whose etiology is unknown so far. The aim was to know the incidence, severity, and symptomatology of the disease and to identify morphologically the fungi associated with diseased trees. A 5-year-old plantation of S. parahybum was studied in the province of Los Ríos, where three rectangular plots of 500 m2 were established. Disease severity was evaluated with a 5-category scale (1=apparently healthy tree, and 5=tree with more than 50% dead tissue). For each plot, three trees were dissected and their tissues were analyzed under three methodological strategies (wet chamber, carrot sandwiches and potato-dextrose-agar (PDA) culture medium).  Disease incidence was low at 1.7% (13 diseased trees ha-1). Diseased trees were found at scale 2, which indicates that they are at an early stage of the disease. Diseased trees showed loss of turgor, paleness and yellowing of leaflets, with young leaves showing reduced size and poor formation. Longitudinal areas of necrosis were observed in the upper third of the stem. The fungi Fusarium sp. 1, Fusarium sp. 2, and Botryodiplodia sp. were isolated and identified, all causing pathogenesis in plants.

Published: July 2022

India is one of the world's largest mega-biodiversity hotspots, with a wide range of ethno-medicinal vegetation, which are being used in treatment of minor to major health problems by local people. In the present ethnobotanical study, in the district of Hisar, Haryana, data were recorded in the form of botanical names, local names, families, and plant parts used with their medicinal characteristics of 41 medicinally important indigenous plant species belonging to 27 families. For it, nine villages were selected randomly of district Hisar and documentation of ethno-medicinal plant species was done through direct and indirect approach. In direct approach; Ayurvedic Doctors, Vaidyas, Hakims, Herbal Healers, Ojhas and related Ethnic Groups of the selected rural areas of the region were interviewed to get reliable knowledge regarding medicinal uses of indigenous plants. Ethno-medicinal information were correlated with available ancient literature and published research articles. The majority of medicinal plants, according to reports, belong to Cucurbitaceae, Liliaceae, Fabaceae, Amaranthaceae, Euphorbiaceae, Asteraceae, Chenopodiaceae, Solanaceae and Lamiaceae families. Leaves in most of the plants have got the maximum ethno-medicinal values. Information generally transmits from one generation to next generation in oral manner in rural ethnic groups and several valuable information are lost without proper documentation.

The semantic harmony is the aesthetic goal that is required to be achieved between the folds of the poetic text, regardless of the reality of this fabric or its roots. Poetic elements so that he can then establish and construct the semantic pattern of the text. Perhaps the modern poet was aware of the dimensions of repetition and its values, so he paid more attention to it, as we find it clearly among the pioneers of free poetry. And the level of its depth and richness and its ability to choose the appropriate form that provides the structure of repetition the largest possible opportunity to devote the vision and the position in a manner that transcends grammatical and linguistic limits to become a musical and semantic tool at the same time.

Introduction: β-Lactamase production is considered one of the most important resistance mechanisms among virulent Pseudomonas aeruginosa isolates. The aim of the study was to detect Extended Spectrum β-Lactamase (ESBL) and Metallo β-Lactamase (MBL) in Pseudomonas aeruginosa obtained from various clinical samples. Materials and Methods: The study was conducted in the Department of Microbiology, Govt. Medical College, Shahdol. All clinical specimens were processed and P. aeruginosa isolates were identified by standard protocols. Antibiotic sensitivity testing for all isolates was done using Kirby-Bauer disc diffusion method. Detection of ESBL and MBL was done by Disc potentiation test. Results: Among 347(27.2%)   isolates of P. aeruginosa, 284(88.2%) were MDR, 139(40%) and 73(21%) were ESBL and MBL producers respectively where 39(11.2%) isolates produced both ESBL and MBL. Conclusion: A high prevalence of MDR, ESBL, MBL positive isolates among P. aeruginosa is increasing at an alarming rate. Thus, proper antibiotic policy and measures to restrict the indiscriminative use of cephalosporins and carbapenems should be taken to minimize the emergence of this MDRPA.
