Authors: Escoto Castillo Ana Ruth , Padrón Innamorato Mauricio , Román Reyes Rosa Patricia
Published: May 2021

La implementación de medidas para controlar la propagación de la Covid-19 en México ha tenido un gran impacto sobre las condiciones, características y procesos de entrada y salida del mercado laboral nacional, modificando las situaciones y expectativas de millones de personas, particularmente a las mujeres- Este trabajo busca revisar y describir la dinámica laboral antes del inicio de la pandemia y una vez flexibilizadas las medidas sanitarias más restrictivas, analizando a los hombres y mujeres en edad de trabajar que conforman la población que se encuentra ocupada (tanto formal como informal), que está desocupada, disponible o no disponible. Este artículo pretende identificar qué rasgos, tanto individuales como del hogar, determinan la pertenencia a alguna de las categorías mencionadas. Los datos provienen de cuatro fuentes y se aplican técnicas estadísticas descriptivas e inferenciales, recurriendo a la construcción de modelos de regresión logística multinomial. Los mayores cambios se observan en el aumento de la población disponible con patrones diferenciados por género, mismos que se observan en las salidas de los empleos formales e informales, así como una mayor probabilidad de estar no disponibles para las mujeres en hogares con menores de edad.

Authors: Yulandari Angelina , Sudarma I Made , Arisena Gede Mekse Korri
Published: May 2021

Tabanan Regency as a rice barn in Bali has also experienced land conversion, particularly rice fields area. The rapid financial expansion requires the development of various infrastructures so that the demand for agricultural land is more enormous. Kediri sub-district is one of the regions that experienced the conversion of agricultural area to non-agricultural which is adequately high in Tabanan Regency. The purpose of this study is to determine the development of the land conversation in the Tabanan Region, differences in farmer’s income that have done the land conversion and those who have not done it, and the components that influence land conversion. The sampling technique is taken by proportional sampling with 40 people. The analysis techniques used are trend analysis, average difference test analysis, and logistic regression models. The result of the study concludes that the development of agricultural land conversion in Tabanan Regions is proceeding to extend. Based on the results of the t-test there is no significant difference between the average income of farmers who have done the land conversion and those who have not. Factors that influence the land conversion at the agricultural level are labor, number of dependents, irrigation systems, and surface area.
Folkcomunicação nas transformações tecnológicas e midiáticas contemporâneas
Authors: Gushiken Yuji
Published: May 2021

A emergência e a afirmação da folkcomunicação como perspectiva teórica na pesquisa em Comunicação atenta para reinvenção de práticas midiáticas e comunicacionais no âmbito das manifestações tradicionais e da cultura popular brasileira. A singularidade da folkcomunicação é sua configuração teórica numa insistente situação de tática das manifestações tradicionais e populares hoje enredadas pelas transformações tecnológicas e midiáticas. Esta condição difusa promovida pelas convergências do popular com o tecnológico equivale, na experiência da vida urbana, às aproximações entre as insistentes precariedades da vida social e o consumo de novas tecnologias. No plano metodológico, o artigo se desenvolve com base em pesquisa bibliográfica, na perspectiva maior da comunicação como cultura, num diálogo com as ciências sociais.
Las carreteras al mar: estudio sobre el impacto de los vertebrados silvestres y los ecosistemas circundantes en dos corredores viales de Colombia

Published: May 2021

La construcción de carreteras al interior o en proximidad de áreas naturales ha sido identificada como una de las principales causas de perdida y fragmentación del hábitat en todo el mundo. En el departamento del Valle del Cauca, Colombia, dos corredores viales, en distintas etapas de desarrollo, comunican a la ciudad de Cali con el puerto de Buenaventura. Para evaluar y cuantificar los impactos que tienen estas carreteras en las poblaciones silvestres de fauna de la zona se desarrolló un proyecto de investigación en dos fases: modelación de corredores y validación en campo. Las interacciones entre las poblaciones de fauna silvestre y estos corredores viales fueron evaluadas y cuantificadas a partir del modelamiento de corredores con información proveniente de los sistemas de información geográfica (SIG) respaldados por datos tomados en campo sobre estructuras de drenaje, atropellamientos y registros de fototrampeo. Se identificaron cuatro zonas prioritarias de cruce para nueve especies de mamíferos. Tras evaluar 738 estructuras viales, se registraron 19 especies utilizando estas estructuras y 38 especies fueron atropelladas en ambas carreteras. Dichas vías difieren en estructuras y trazados, sin embargo, comparten sus problemáticas como la falta de estructuras viales preexistentes adecuadas para el paso de fauna, su uso como refugio y el desarrollo poco estructurado en su periferia son las causas del efecto de barrera que limita la conectividad y flujo génico de animales en esta zona.

Published: May 2021

La investigación sobre Study Engagement adquirió fuerza en Educación Superior por su valor predictivo del rendimiento, abandono y bienestar del estudiante. Sin embargo, los modelos explicativos provienen del contexto ocupacional y escolar sin adaptaciones precisas al contexto universitario. El objetivo de investigación buscó caracterizar los correlatos conductuales del Study Engagement desde la experiencia de estudiantes de segundo año de ingeniería chilenos para aportar mayor claridad sobre este constructo. Se realizó una investigación cualitativa con enfoque fenomenológico y muestreo intencionado de tipo homogéneo. Se entrevistó a 12 estudiantes que, previa medición de su Engagement, cumplieron con los criterios de muestreo. Se realizó un Análisis Temático que mostró la existencia de 3 categorías de comportamientos “engaged”: planificación, implicación y vínculo social. Las causas principales del Engagement se vincularon con prioridades vitales, metas y organización del tiempo. El afrontamiento se enfocó en autoinstrucciones, motivaciones vitales y apoyo social. Se concluye la existencia de una coherencia parcial entre la experiencia de los estudiantes, la conceptualización del constructo y evidencia empírica previa. Estos hallazgos pueden ser de relevancia para ajustar de mejor forma la conceptualización acorde a la experiencia estudiantil. Sus implicancias pueden afectar además la construcción de instrumentos y comprensión de resultados previos.

Fractional spectral integral methods for valuing cryptocurrency asset flow fractional differential equations.
Authors: Moutsinga Claude , Pindza Edson , Mare Eben
Published: May 2021

Since its inception in 2009, the cryptocurrency market has grown
considerably. Several authors have proposed models to explain the price
movements of assets in this new emerging market. However, only few
researches have been done using the dynamical approach. This paper
proposes a robust time fractional spectral method for studying a three
dimensional fractional differential equation that models cryptocurrency
asset flow obtained by utilizing the concept of liquidity price. The
method relies on fractional spectral integration matrix operator
approach. Numerical simulations are conducted to show efficiency of the
numerical method on the fractional cryptocurrency model compared to
existing methods.

Fishbone perforation, a severe complication causing damage to nearby
organs, is difficult to diagnose because the patient and family cannot
remember the history of fishbone ingestion exactly. A detailed history
of eating, as well as a thorough physical examination and diagnostic
imaging, are needed to make an accurate diagnosis.
Asymmetric pathogen spillover favors exotic plants over natives
Authors: Waller Lauren , Allen Warwick , Black Amanda , Tonkin Jonathan , Tylianakis Jason , Wakelin Angela , Dickie Ian
Published: May 2021

Exotic plants can escape from specialist pathogenic microorganisms in
their new range, but may simultaneously accumulate generalist pathogens.
This creates the potential for pathogen spillover, which could alter
plant-competitive hierarchies via apparent competition. To assess the
potential for and consequences of pathogen spillover in invaded
communities, we conducted a community-level plant-soil feedback
experiment in experimental communities that ranged in the extent of
exotic dominance, using next-generation sequencing to characterize
sharing of putatively-pathogenic, root-associated fungi (hereafter,
‘pathogens’). Exotic plants outperformed natives in communities, despite
being subject to stronger negative plant-soil feedbacks in monoculture
and harboring higher relative abundance of pathogens. Exotic plants made
more general associations with pathogens, making them more prone to
sharing pathogens with natives and exerting apparent competition. These
data suggest that exotic plants accumulate generalist pathogens that are
shared with native plants, conferring an indirect benefit to exotic,
over native plants.
Simulating Spatial and Temporal Dynamics of Soil Moisture and Gully Flow Using Improved Grid-Xinanjiang Model with a Prior Parameter Estimates
Authors: Tong Bingxing , Li Zhijia , Yao Cheng , Liu Moyang , Gong Junfu
Published: May 2021

To systematically generalize the influence of gullies on floods, a
distributed model named Improved Grid-Xinanjiang (GXAJ), and a priori
parameters estimation scheme based on the Global Digital Soil Mapping
System (SoilGrids) are proposed. Within a watershed divided into a
series of orthogonal cells, shallow furrows and trenches inside the
cells are conceptualized as primary gullies, in which water movement is
simulated by kinematic wave equation considering the gullies density,
and well-developed grooves between cells are considered as main gullies,
where water moves as a kinematic wave and enters the rivers. The
simulation of 27 flood events in the Tunxi watershed of Anhui Province
from 2008 to 2017 was implemented, and the simulation results were
compared with that of Xinanjiang model (XAJ). The relative runoff volume
error and flood peak error of the GXAJ model and XAJ model are 8.4% and
10.7%, 8.9% and 12.1%, respectively. The GXAJ model outperforms in
the simulation of flood peak, and is capable of producing the dynamics
of soil water and gullies flow. The spatial characteristics and the
sensitivity of parameters, free storage capacity and gullies density, at
various phases, that is, initial, rise, peak, fall and tail, have been
analyzed. The value of free storage capacity decreases and then
increases with the increase of altitude and distance from the river. The
gullies density in the bank and ridge area is greater than that in the
middle of the slope segment. Sensitivity analysis shows that gullies
density has the noticeable influence on the relative runoff volume error
and Nash-Sutcliffe coefficient in the rise phase, while free water
storage capacity has a significant effect on the relative runoff volume
error during the flood rise phase and Nash-Sutcliffe coefficient in peak
phase, respectively.

Published: May 2021

Wei River is the largest tributary of the Yellow River, and in recent
decades, water resource has changed significantly. Identifying the
characteristics and influencing factors of streamflow change in Wei
River is needed for development of effective management strategies and
economic development for the region and entire Yellow River basin. The
analyzations were based on streamflow records from 1957 to 2018 at five
hydrological stations as well as precipitation and air temperature data
from 22 meteorological stations. Mann-Kendall method and Pettitt test
were used to analyze trends and transition years of hydrometeorological
variables. Double mass curves (DMC) were used to quantify the impact of
climate changes and anthropogenic activities on streamflow change. The
results showed that: the annual average streamflow decreased
significantly in the upper reaches (URWR), middle reaches (MRWR) of the
main Wei River, Jing River Basin (JRB), Beiluo River Basin (BLRB) as
well as the whole Wei River Basin (WWRB). There were transition years
existed in these reaches and concentrated in 1990s. The annual
precipitation showed a significant downward trend in the MRWR, LRWR,
BLRB and WWRB (P<0.01). Air temperature in all reaches rise
significantly (P<0.01). Analysis of land use from 1980 to 2020
indicated that residential land and grassland increased markedly. The
results of DMC showed that anthropogenic activities were the dominant
factors for streamflow reduction, accounting for 52.96%-92.2%. For
different reaches, the intensity of human activities (domestic water,
agricultural irrigation, industrial water, soil and water conservation
measures and reservoirs construction, etc.) was different, resulting in
the difference of contribution rate. Relevant research results provide
basis for scientific regulation of water resources in Wei River Basin.

Authors: Stańko Stanisław , Mikuła Aneta
Published: May 2021

Przedmiotem analizy była produkcja ziemniaków, zużycie krajowe i obroty handlu zagranicznego (eksport i import) w Polsce w latach 2001-2019. W oparciu o wyniki analiz określono średniookresową projekcję (na 2025 r.) obejmującą produkcję, kierunki wykorzystania w kraju i obroty handlu zagranicznego ziemniakami i ich przetworami. Analizowane dane pochodziły z GUS oraz IERiGŻ-PIB. Produkcja ziemniaków w Polsce w latach 2001-2019 charakteryzowała się tendencją spadkową. Wolniejszy spadek zbiorów niż powierzchni wynikał z poprawy plonowania. W zużyciu krajowym występowały różnokierunkowe tendencje: spadkowa w spożyciu ziemniaków ogółem, w eksporcie ziemniaków nieprzetworzonych, w przetwórstwie w gorzelnictwie i w stratach w przechowalnictwie oraz wzrostowa w przetwórstwie spożywczym i pozostałym przemysłowym. W handlu zagranicznym zaobserwowano poprawę dodatniego salda handlu przetworami z ziemniaków oraz pogłębianie się ujemnego salda handlu ziemniakami. Z projekcji rozwoju na 2025 r. wynika, że produkcja ziemniaków w Polsce może wynosić 7250- 7540 tys. t, a zapotrzebowanie - 7430-7570 tys. t. Import niezbędny ziemniaków świeżych może wynosić rocznie 30-180 tys. t.

The pathogenesis of type 2 diabetes (T2D) might change with increasing age. Here, we used a stratification based on age of diagnosis to gain insight into the genetics and causal risk factors of T2D across different age-groups. We performed genome-wide association studies (GWAS) on T2D and T2D subgroups based on age of diagnosis (<50, 50–60, 60–70, and >70 years) (total of 24,986 cases). As control subjects, participants were at least 70 years of age at the end of follow-up without developing T2D (N =187,130). GWAS identified 208 independent lead single nucleotide polymorphism (SNPs) mapping to 69 loci associated with T2D (P < 1.0e−8). Among others, SNPs mapped to CDKN2B-AS1 and multiple independent SNPs mapped to TCF7L2 were more strongly associated with cases diagnosed after age 70 years than with cases diagnosed before age 50 years. Based on the different case groups, we performed two-sample Mendelian randomization. Most notably, we observed that of the investigated risk factors, the association between BMI and T2D attenuated with increasing age of diagnosis. Collectively, our results indicate that stratification of T2D based on age of diag-nosis reveals subgroup-specific genetics and causal determinants, supporting the hypothesis that the pathogenesis of T2D changes with increasing age.
Fiber Optic Sensor Design and Prototyping for Humidity Detection in Biogas Reactors
Authors: ŞAHİN Murat , HAYBER Şekip Esat
Published: May 2021

In biogas reactors, it is vital to monitor the condensation of water vapor with increasing humidity. The use of fiber optic-based sensors that allow this control to be done online quickly and reliably facilitates the process. In this study, a fiber-optic water vapor and condensation sensor was designed and implemented for biogas reactors. It enables the detection of water due to water vapor and condensation that will increase humidity level based on the combination of fiber reflection losses and longitudinal alignment losses. By creating a very low-cost sensor mechanism that can react quickly and is not affected by environmental variables other than the parameter to be detected, the increasing water vapor and the initial moment of the condensation can be detected with high precision and speed.
Monitoring of Forest Resource Health in Akure Reserve, Ondo State Nigeria
Authors: Ijaware V. Ayodele
Published: May 2021

Remote sensing and Geographic Information System (GIS) over the years play great role when integrated in the right way to study changes taken place on the planet. Most times, these changes are natural and beyond human interaction but often times too, the changes are occasioned by human factor in the search for development and daily survival. In achieving this, the forest is made to suffer unnecessarily thereby reducing its health status through excessive forest resources depletion. This study focusses on the monitoring of forest resource health in Akure forest reserve between 1972 and 2013 using Landsat MSS of 11/11/1972, Landsat TM of 17/12/1986, Landsat ETM+ of 03/01/2002, and Landsat ETM+ of 02/02/2013 downloaded from USGS website. Minimum Mahalanobis distance supervised classification was used to categorize land use pattern in the study area while ILWIS 3.2 Academic GIS was deployed to perform NDVI image classification analysis with a precision of 0.01m to determine the health status of the forest reserve. The analysis revealed that the total annual rate of depletion for 41 years stood at 2.46% while forest health status diminished during the study period as NDVI value ranged between -0.04to +0.44 (1972) to -1.0to +1.0 in 2013. The study recommends that open areas which are not homogeneous forest (shrub/grass land) detected in this study should be re-planted with varieties of tree species without delay to allow carbon sequestration for overall human benefits.
Development of Mathematical Model to Study the Variation Temperature due to the Collision of
Authors: Dhobi Saddam Husain , Panthi Arjun , Panthi Subash , Subedi Roshan
Published: May 2021

To study the variation of temperature with the collision of the air molecules, with aircraft the authors consider the random velocities of the air molecules or aerosol and aircraft. After this, the authors start to develop and extend the old relation of gases, collision, velocities, and temperature. On combining, the authors derived a new equation and relation among these parameters. The derivation for this work assumes some suitable and considerable, assumptions based on collision theory. The relation shows, on collision between the aircraft and air molecules the velocity of the aircraft does not change while the velocity of the air molecules goes on change, which is our goal. 

The change in velocity of gases is used to develop and study the variation of temperature of the atmosphere, the variation of temperature takes place because the speed of aircraft and air molecules are exchangeable in some cases. Therefore, two relations are developed (24) and (25), finally, which depend upon the initial velocities of aircraft and air molecules. On considering the case for initial velocities of aircraft is greater than initial velocities of air molecules, after the collision, the velocities of gases go on the increase, and hence the temperature increase and vice-versa in case of initial velocities of aircraft is less than the initial velocity of air molecules.

Published: May 2021

Introduction

Few studies have assessed patterns of substance use among Canadian adolescents. This cross-sectional study examined substance use classes among Canadian secondary school students and associations with anxiety and depression.

Methods

This study used data from Year 6 (2017/18) of the COMPASS study. Students (n = 51 767) reported their substance use (alcohol, cannabis, cigarette and e-cigarette use) and anxiety and depression symptoms. We employed latent class analysis to identify substance use classes and multinomial logistic regression to examine how anxiety and depression were associated with class membership.

Results

Overall, 40% of students indicated having anxiety and/or depression (50% in females; 29% in males) and 60% of students reported substance use (60% in females; 61% in males). We identified three substance use classes: poly-use, dual use, and non-use. Females with both anxiety and depression had the highest odds of being in the poly-use class compared to the non-use class (odds ratio [OR] = 4.09; 95% confidence interval [CI]: 3.59–4.65) followed by females with depression only (OR = 2.65; 95% CI: 2.31–3.04) and males with both anxiety and depression (OR = 2.48; 95% CI: 2.19–2.80). Symptomatology was also associated with belonging to the dual use class except among males with anxiety only (OR = 1.13; 95% CI: 0.94–1.37).

Conclusion

Canadian secondary school students are engaging in dual and poly-substance use, and anxiety and depression were associated with such use. Females had a higher prevalence of anxiety and depression and should be a priority population for mental health programming.

Lymphoma is the third leading cause of malignant neoplasms (MNs) in children. Childhood lymphoma is characterized by the prevalence of highly aggressive variants with high proliferation activity and rapid tumor dissimilation. Prolonged diagnosis becomes a reason of advanced-stage therapy. Despite the good results of long-term survival rate in patients, exceeding 90% even with late (III-IV) stages of lymphomas, the persistence of pathogenic (including multi-drug resistant) microorganisms in the patient's body becomes a major therapeutic problem, contamination of which occurs during the patient's stay in various medical organizations at the stage of diagnostics. The case reports of fatal infectious complications with the development of sepsis caused by polyresistant microorganisms in 2 children with anaplastic large cell lymphoma stage IV are presented in this article. Both case reports are unfavourable, despite the use of all medications and effective treatments. The analysis of diagnostic errors and necessity of cancer alarm generation in medical staff and patients' parents will make it possible to reduce the duration of diagnosis and probability of contamination of patient’s body with multi-resistant flora.

In adults with oncological diseases, most PET/CT studies with 18F-FDG are performed using a scanning protocol with a reduced scanning area (r-PET/CT). In pediatric oncology, PET/CT with 18F-FDG is recommended to be performed in the «whole body» mode. We hypothesized that the use of r-PET/CT in children with Hodgkin's lymphoma (HL) may be sufficient without loss of diagnostic value. Materials and methods of research: a comparative analysis of PET/CT scanning protocols in «whole body» mode and r-PET/CT mode in children with HL was carried out. The retrospective analysis included 105 patients aged 0–18 years. All patient underwent primary whole-body PET/CT examinations at the time of initial staging and intermediate follow-up PET/CT scan after 2-cycle of chemotherapy. 210 PET/CT studies were retrospectively analyzed. Results: in 94 (89,5%) of 105 patients the identified lesions were localized within the area of the field-of-view of r-PET/CT, and additional lesions detected in 11 (10,5%) patients in the whole-body PET/CT examinations have not affected the results of staging and management. Conclusion: the detection of additional foci of pathological metabolic activity beyond r-PET/CT has no further impact on the stage of the disease, the protocol of treatment and the evaluation of the early response to the therapy. The advantage of r-PET/CT protocol is the reduction in radiation exposure and study time, which is very important for pediatric patients with HL.

Published: May 2021

The authors investigated the mechanism of interconnection of ideas of global constitutionalism as a social concept with social reality, denoting the socio-historical conditions of its origin and development. The article proves that emergence and development of the social concept of global constitutionalism is due to a set of socio-economic, socio-political, historical and legal conditions that, in their interrelation and interdependence, determined the main features of this social concept, as well as the forms and stages of its implementation in the social reality of national societies and states as well as internationally. These conditions for the emergence and development of the social concept of global constitutionalism can be classified into a number of stages: the stage of the formation of the social concept of global constitutionalism, the definition of its system-forming features and the formulation of global democratic values; the stage of creating international and supranational political and legal institutions acting as unified control centres of regulation and control, which consists in the forcible export of values of constitutional democracy on a planetary scale.

Erosi tanah dapat menyebabkan terjadinya degradasi lahan dan lingkungan. Pengukuran erosi tanah sudah banyak dilakukan dengan tujuan untuk menentukan banyaknya tanah yang terangkut erosi sehingga dapat dilakukan pencegahan untuk meminimalisir terjadinya erosi. Penelitian ini bertujuan untuk mengetahui besarnya erosi pada lahan yang ditumbuhi tanaman aren (Arenga pinnata Merr) dengan tiga tingkatan umur tanaman di Kecamatan Lintau Buo Utara, Sumatra Barat. Penelitian dilakukan dari bulan November sampai Desember 2020 yang dimulai dengan melakukan survei pendahuluan di lapangan yaitu meninjau dan menentukan lokasi serta melakukan penentuan titik-titik pengamatan pada masing-masing penggunaan lahan. Pengukuran erosi tanah dilakukan dengan metode petak kecil pada lahan aren yang berbeda umurnya, serta dari lahan yang memiliki vegetasi rumput sebagai pembanding. Disamping tanah tererosi, beberapa sifat fisika tanah juga diamati, diantaranya tekstur, bahan organik, permeabilitas, bobot isi, dan porositas tanah. Hasil penelitian menunjukkan bahwa erosi pada lahan yang ditumbuhi aren lebih rendah dari lahan semak belukar. Besarnya tanah tererosi pada padang rumput mencapai 0,99 ton/ha, sedangkan pada lahan di bawah tanaman aren yaitu 0,91, 0,62 and 0,95 ton/ha pada tanaman berumur 6, 15, dan 25 tahun, secara berturut-turut. Hal ini didukung oleh sifat fisika tanah yang lebih baik di bawah lahan yang ditumbuhi aren, yang dicirikan oleh kandungan bahan organik yang tinggi (14,10-17,61%), bobot volume tanah yang rendah (0,44-0,63 g/cm3), total ruang pori tanah yang tinggi (76-83%), dan permeabilitas yang agak cepat (8,23-10,12 cm/jam). Tekstur tanah didominasi oleh partikel halus (debu dan liat) dengan kelas tekstur liat pada semak belukar dan liat berdebu pada lahan aren.

Published: May 2021

The research was conducted in 2016–2017 in the 6,613-ha Kozubów Landscape Park (KLP). It focused on the occurrence and distribution of amphibians and reptiles, the biology and phenology of selected species and the existing threats.

The KLP, established in 1986, is located in the Nida Basin, covering the eastern part of the Wodzisławski Ridge. This area is characterised by diverse landscape features formed on a chalk substrate. A significant part of the KLP (48.8%) is covered by forests growing on the tops and slopes of loess hills intersected by valleys and gorges. Hornbeam forests and fragments of riparian forests have retained a semi-natural character. The steep, non-forested slopes with a southern and south-western exposure are overgrown by thermophilic xerothermic grasslands. Xerothermic plant communities show a relatively low species diversity, because the main type of substrate in this area is loess. Two nature reserves, Polana Polichno and Wroni Dół, are located within the KLP borders.

The following amphibian species were found in the KLP: smooth newt (Lissotriton vulgaris L.), great crested newt (Triturus cristatus Laur.), European fire-bellied toad (Bombina bombina L.), common spadefoot toad (Pelobates fuscus Laur.), common toad (Bufo bufo L.), European green toad (Bufotes viridis Laur.), European tree frog (Hyla arborea L.), edible frog (Pelophylax esculentus L.), pool frog (Pelophylax lessonae Cam.), moor frog (Rana arvalis Nilss.) and common frog (Rana temporaria L.). Reptiles are represented by the sand lizard (Lacerta agilis L.), viviparous lizard (Zootoca vivipara Jacquin), slow worm (Anguis fragilis L.), grass snake (Natrix natrix L.), smooth snake (Coronella austriaca Laur.) and common European adder (Vipera berus L.). The study also included the phenology and reproductive biology of common toad and common frog.

Major threats to the herpetofauna are posed by grass burning. Unfavourable changes include decreasing water levels and drying out of water bodies.

Lubricants that are based on vegetable oils and other renewable resources are the subject of many research studies and can be used in various applications, especially in the food industry, which is characterized by the high quality requirements related to the necessity to develop biodegradable lubricants that are environmentally friendly and do not contain harmful components and are safe to use for people. The objective of the described research was to obtain a base oil with a certain viscosity, which is higher than the viscosity of the initial vegetable oil, and certain lubricating properties. The initial oil derived from Crambe abyssinica was subjected to oxidation in the presence of N-hydroxyphthalimide with or without supercritical CO2 as a solvent. As a final result of this study, base oils meeting the viscosity requirements and having high biodegradability were obtained. The Raman spectra of the modified vegetable oils were evaluated and they were used for the initial assessment of the composition and the evaluation of the presence of harmful chemical compounds.
