Change In Nitrogen Dioxide (No2 ) Concentration Due To The Lockdown Amid The Covid-19 Pandemic In India
Authors: Islam Zubairul , Singh Sudhir Kumar , Ahirwar Saroj 
Published: December 2021

The study aimed to examine the change in the concentration of nitrogen dioxide due to the lockdown amid the COVID-19 pandemic in India at the district level using Sentinel-5P TROPOMI. The spatio-temporal characteristics of the tropospheric column NO2 concentration during 45 days of the lockdown were compared with the same days of 2019. Further, to model spatially varying relationships of NO2 during the lockdown period, it was given as a dependent variable whereas NO2 during the pre-lockdown period was considered as an independent variable. Results show that the mean NO2 concentration was reduced from 0.00406 mol/m2 before the lockdown (2019-03-25 to 2019-05-10) to 0.0036 mol/m2 during the lockdown period (2020-03-25 to 2020-05-10). The maximum decline of NO2 concentration was observed in Gautam Buddha Nagar and Delhi. This indicates the high level of atmospheric pollution due to the excess use of fuel in human activities. The results of the Ordinary Least Squares (OLS) method show a strong positive relationship between both variables. Positive standard residuals indicate that the concentration of NO2 has reduced more than expected as per the OLS model. The z-score (24.11) was obtained from spatial autocorrelation. It indicates that residuals are highly clustered and there is less than a 1% likelihood that this clustered pattern could be a result of a random chance. The highest decrease was observed in districts/urban agglomerations of Gautam Buddha Nagar (-40%), Delhi (-37%), Greater Bombay (-31%), Hyderabad (-29%), Faridabad (-29%), Bangalore Urban (-28%), Gandhinagar (-27%), Chennai (-27%) and Gurgaon (-26%) respectively.

Published: December 2021

The article considers the existing classifications of thermal burns by the depth of the lesion. The analysis and comparison of different classifications among themselves is carried out. The problems that may arise in forensic medical practice in determining the severity of thermal burns, which are associated with the use of different classifications, are demonstrated. The use of different classifications of burns according to the depth of the lesion can lead to incorrect determination of the severity of injuries when compiling the "Expert Conclusion". Methodological approaches that will avoid this are presented.
The aim of the work. Elaboration of methodological approaches to the use of modern classifications of burns, which are introduced in Ukraine and in other countries, during forensic medical examinations of thermal injuries.
Materials and methods. Analysis, synthesis, comparison and analogy of printed and electronic legal documents of Ukraine, domestic and foreign forensic and medical literature on burn injury.
Results. Analysis and comparison of different modifications of burns classification by depth of injury revealed that modern classifications by combinations of numbers and letters differ from the classification of burns by depth, which is used in forensic practice in Ukraine in determining the severity of thermal injuries. The forensic expert during the examination in cases of thermal injury examines the medical records that contain information about the treatment of the victim. Victims can be treated in various medical institutions both in Ukraine and abroad. Thus, different classifications are used in the formulation of the diagnosis, which can lead to incorrect determination of the severity of the injury caused by high temperature. The result is a biased "Expert Conclusion", which may later be considered inadequate evidence in criminal proceedings. To prevent erroneous assessment of the degree of burns, the expert must find out what classification of burns is used in making a clinical diagnosis, and interpret the specified degree of burns in accordance with the gradation of burns, which regulates the activities of forensic experts.
Conclusion. At present, the «Rules of forensic determination of the severity of injuries», which were approved in Ukraine in 1995, don't provide adequate methodological support for forensic expert research, which should correspond to the current level of development of medical science and clinical practice. The introduction of the achievements of world medicine into the domestic forensic medical practice should be facilitated by modern legal documents regulating the activities of forensic medical institutions of Ukraine.

Authors: SZWEJKOWSKA BEATA , BIELSKI STANISŁAW 
Published: December 2021

Badaniami objęto dwie odmiany soczewicy jadalnej Tina i Anita, uprawiane w zróżnicowanych technologiach: nisko-, średnio- i wysokonakładowej. Zwiększenie intensywności technologii produkcji soczewicy powodowało wzrost wielkości i wartości plonu, kosztów bezpośrednich produkcji, nadwyżki bezpośredniej, wskaźnika efektywności ekonomicznej, a obniżenie jednostkowego kosztu produkcji nasion. Największy przyrost nadwyżki bezpośredniej, wynoszący średnio dla odmian 101%, uzyskano po zwiększeniu intensywności produkcji z poziomu technologii nisko- do średnionakładowej. Odmiana Anita charakteryzowała się korzystniejszymi wskaźnikami oceny ekonomicznej w porównaniu z odmianą Tina.
Plonowanie pszenicy jarej uprawianej w krótkotrwałej monokulturze w zależności od międzyplonu i sposobu odchwaszczania
Authors: GAWĘDA DOROTA , KWIATKOWSKI CEZARY A. 
Published: December 2021

W dwuczynnikowym doświadczeniu polowym uwzględniono rodzaje przyorywanych corocznie międzyplonów ścierniskowych (bez międzyplonów − obiekt kontrolny, gorczyca biała, facelia błękitna, mieszanka strączkowych – łubin wąskolistny + groch siewny pastewny) oraz sposób odchwaszczania pszenicy jarej (mechaniczny, mechaniczno-chemiczny, chemiczny). Celem badań była ocena wpływu wybranych międzyplonów ścierniskowych i sposobu odchwaszczania na wielkość plonu ziarna oraz wybrane elementy plonowania pszenicy jarej uprawianej w krótkotrwałej monokulturze. Niezależnie od sposobu pielęgnacji, mieszanka łubinu wąskolistnego z grochem siewnym pastewnym powodowała istotny wzrost plonu ziarna pszenicy jarej w porównaniu z obiektem bez międzyplonu ścierniskowego, wynoszący 9,2%. Udowodniono również zmniejszenie plonu po międzyplonach z gorczycy białej i facelii błękitnej w porównaniu z obiektem z mieszanką roślin strączkowych, wynoszący odpowiednio 6,5 i 5,4%. Najwyższy plon ziarna pszenicy jarej odnotowano w wariancie z kompleksową mechaniczno-chemiczną pielęgnacją zasiewów.
Wpływ zagęszczenia roślin na plonowanie i jakość surowca nagietka lekarskiego (Calendula officinalis L.)
Authors: KRÓL BEATA 
Published: December 2021

Polska zajmuje czołowe miejsce w Europie w uprawie roślin zielarskich. Jednym z ważniejszych gatunków uprawnych jest nagietek lekarski, mający szerokie zastosowanie w przemyśle farmaceutycznym, kosmetycznym i spożywczym. Celem przeprowadzonego doświadczenia było zbadanie wpływu zróżnicowanego zagęszczenia roślin (20, 40, 60 i 80 roślin na m2) na ich wybrane cechy morfologiczne oraz plony i jakość koszyczków kwiatowych nagietka lekarskiego. Najwięcej koszyczków kwiatowych (zarówno pod względem liczby, jak i masy) w przeliczeniu na pojedynczą roślinę stwierdzono przy zagęszczeniu 20 szt. · m-2. Natomiast najwięcej koszyczków kwiatowych w przeliczeniu na jednostkę powierzchni zanotowano w obiekcie o zagęszczeniu 40 szt. · m-2, w którym uzyskano także największy plon surowca. Wzrastające zagęszczenie roślin nie miało istotnego wpływu na wielkość koszyczków (z widoczną jednak tendencją do zmniejszania ich średnicy). Zwiększające się zagęszczenie roślin powodowało spadek zawartości olejku eterycznego, nie miało natomiast wpływu na poziom flawonoidów.
Wpływ warunków opadowo-termicznych na plonowanie średnio późnych i późnych odmian ziemniaka jadalnego
Authors: KOŁODZIEJCZYK MAREK 
Published: December 2021

Ocenę wpływu warunków pogodowych na kształtowanie się wielkości i struktury plonu bulw ziemniaka prowadzono w latach 2006-2011. Badano sześć średnio późnych i późnych odmian ziemniaka jadalnego: Jelly, Medea, Niagara, Syrena, Ursus i Zeus. Plon ogólny bulw w poszczególnych latach badań kształtował się w szerokim zakresie od 19,1 do 66,9 t . ha-1, natomiast plon handlowy od 17,1 do 61,1 t . ha-1. Największe plony stwierdzono w sezonie charakteryzującym się nadmierną w stosunku do potrzeb ilością opadów w maju i czerwcu oraz ich umiarkowanym niedoborem w pozostałych miesiącach, najmniejsze natomiast w roku skrajnie wilgotnym. Warunki opadowo-termiczne istotnie różnicowały także strukturę plonu bulw. Niedobór opadów w maju i czerwcu wpływał niekorzystnie na liczbę bulw zawiązanych przez rośliny ziemniaka. Z kolei większa w stosunku do potrzeb ilość opadów w lipcu korzystnie oddziaływała na średnią masę bulwy. Odmiany ziemniaka istotnie różniły się wielkością plonu ogólnego i handlowego bulw, liczbą zawiązanych bulw, ich średnią masą oraz udziałem frakcji bulw handlowych i dużych w plonie ogólnym.
Charakterystyka meksykańskich genotypów pszenżyta jarego pod względem ważniejszych cech plonotwórczych
Authors: KRAMEK ANETA , KOCIUBA WANDA 
Published: December 2021

. Praca miała na celu ocenę cech plonotwórczych 38 genotypów pszenżyta jarego pochodzących z Meksyku. Ziarniaki badanych obiektów wysiewane były na jednopowtórzeniowych poletkach (2 m2) w 4-letnim cyklu doświadczeń polowych w latach 2005–2008 w Gospodarstwie Doświadczalnym Uniwersytetu Przyrodniczego w Czesławicach koło Nałęczowa. W okresie dojrzałości pełnej na każdej badanej formie dokonano pomiaru wysokości roślin oraz cech plonotwórczych kłosa, takich jak: długość kłosa i liczba kłosków w kłosie, liczba i masa ziarn z kłosa, płodność kłoska, masa 1000 ziarn. Określono również zawartość białka w ziarnie badanych genotypów. Otrzymane wyniki wskazują na zróżnicowanie badanych form pod względem ważniejszych cech plonotwórczych, szczególnie liczby i masy ziarn z kłosa, na co wskazują duże wartości współczynników zmienności dla tych cech (odpowiednio: V = 12,1% oraz V = 15,5%). Istotna współzależność pomiędzy masą ziarn z kłosa i MTZ (rxy = 0,425) wskazuje, że selekcja prowadzona w kierunku dużej masy ziarn z kłosa może mieć korzystny wpływ na dorodność ziarna u pszenżyta.

Published: December 2021

Abstract
In this article, we consider a Lamé system with a delay term in the internal fractional feedback. We show the existence and uniqueness of solutions by means of the semigroup theory under a certain condition between the weight of the delay term in the fractional feedback and the weight of the term without delay. Furthermore, we show the exponential stability by the classical theorem of Gearhart, Huang and Pruss.

Risks to the National Security Generated By the Widespread Use of Cryptocurrency
Authors: Bobric George-Daniel 
Published: December 2021

Abstract
The pronounced multi-domain technologicalization specific to the last decades has had a significant impact on all areas of activity, including the financial one. The use of cyberspace to facilitate the actions undertaken in the monetary activity has generated the development of this field to the point where virtual currencies have been created and new technologies have been developed to support their use. Like any emerging domain, the cryptocurrency field and the related technology are in a relatively early stage and exclusively imply operating in cyberspace, thus generating security risks in the event of the involvement of malicious entities in illicit activities. In this context, it is worth analyzing how the improper use of the crypto domain can lead to various risks to national security.
Packing and Unpacking Grammar – Towards a Communicative Approach to Teaching Language Structures
Authors: Dragomir Isabela-Anda , Niculescu Brânduşa-Oana 
Published: December 2021

Abstract
Creating classroom activities which really get students to communicate in a natural and meaningful way remains a timely challenge when it comes to teaching a foreign language. This article sets out to revisit the traditional trifecta based on the three Ps (presentation, practice, production) and reincorporate it in a set of specific elements that ensure a successful outcome of language learning activities. With particular focus on grammar, the paper aims to deconstruct the steps and procedures behind five important aspects to be taken into consideration when planning and conducting activities that target structures of language and their practice in a communicative manner, with the ultimate goal of linking the often sterile theory of grammar with contextualized models and tasks.
Equal Opportunities Through Education
Authors: Marcu Maria 
Published: December 2021

Abstract
An inclusive society is a society that offers its members equal opportunities to participate in all aspects of public life, without discrimination, by exercising rights and assuming responsibilities so that progress is equally desired by the individuals and the society to which they belong. The human personality is formed by the interaction of the biological (heredity) with the factors of the social environment and under the influence of education. That is why it is necessary for education to be a modeling continuum, a process that begins in the family and is continued in school, the nucleus around which the free, independent, creative personalities of future adults will be formed. Today’s children are tomorrow’s adults, the ones who will make their mark on the future society. Whether tomorrow’s society will be an inclusive society or whether it will raise barriers and generate hostility depends on how we form the young generation today. This exploratory research, based on the analysis of official documents, statistics and concrete data of the observed reality, highlights important aspects regarding the access to education of disadvantaged groups, in a society that wants to be inclusive.
Physical Activities and their Characteristics During Pandemic Times

Published: December 2021

Abstract
In this paper we wanted to present some aspects and characteristics observed in the specialized works and from the experience gained in performing physical activities during the COVID-19 pandemic. This period was a complicated one both in terms of physical distancing and emotionally. We no longer had the right to leave our houses, except to get what was strictly necessary, not to meet with family members or friends, cultural and sports activities were suspended, and all this caused an increasingly visible state of sedentary lifestyle. All the restrictions of this period had a negative effect mainly on the brain and the dynamics of the human body, and they are detailed in the following pages.
Automatic Identification of Products – A Way of Streamlining the Logistical Support of the Military Unit

Published: December 2021

Abstract
The new products provided by the development of information technology (scanners, barcodes, RFIDs, etc.) can currently provide methods and techniques towards achieving important savings in terms of management of logistical support of military units, especially in terms of efficiency in providing material goods to combat forces that are preparing and training through military exercises. I set out to make an “x-ray” of this way of improving the logistical support, especially through the method of identification by labels that use radiofrequency (Radio Frequency Identification/RFID).
The Impact of Some Emerging Technologies in Modern Military Actions
Authors: Raţiu Aurelian , Roşu Onisim 
Published: December 2021

Abstract
Among the emerging technologies, artificial intelligence represents nowadays an area of interest for all of the states around the world, making the technological progress a huge step in human evolution. The future role of the man in military actions will not be to fight in the field anymore, making decisions on how and when to use the weapons in order to stop the incoming enemy while also respecting the international laws. With the help of technology, humanity could provide its much needed security and put an end to conflicts regardless of their nature, because devices are not capable of emotions and subjectivism, making them transparent and objective and transforming the decision making process into a simpler, fairer and legal action. Technology represents the future and man should adapt to it as soon as possible in order to reach the best outcomes even when it comes to war.
