The development of computer and digital technology contributes to the growth of information flows transmitted through open and closed communication channels. In many cases, this information is confidential, financial, or commercial in nature and is of value to its owners. This requires the development of mechanisms to protect information from unauthorized access. There are two fundamental areas of secure data transmission over the open communication channels – cryptography and steganography. The fundamental difference between them is that cryptography hides from others the content of the message, and steganography hides the very fact of the message transmission. This paper is devoted to steganographic methods of data concealment, which are less researched than cryptographic, but have significant potential for use in a variety of applications. One of the important characteristics of most methods is their effectiveness. In general, efficiency is assessed in the context of solving specific problems. However, the most common criteria for the effectiveness of steganographic methods are the amount of hidden data and the method of transmitting the secret key to the receiving party, which will not allow the attacker to intercept it. Because media files make up a significant portion of network traffic, a digital image is chosen as the stegocontainer. It is proposed to determine the coordinates of the embedding location on the basis of iterative functions. The advantage of their use is the compactness of the description of the coordinates of the pixels in which the data will be hidden. In addition, it is proposed to use the Diffie-Gellman algorithm to transfer the parameters of iterative functions to the receiving side. This method of key distribution makes the steganographic method less vulnerable to being stolen by an attacker. The second performance criterion is the amount of hidden data. The paper found that the moderate addition of multiplicative noise makes it possible to increase the amount of hidden data without significantly reducing the visual quality of the stegocontainer. To analyze the distortions in the image-stegocontainer, which are due to the influence of noise and modification of the lower bits of pixels, the method of a quantitative assessment of visual quality is used, which is based on the laws of visual perception. Keywords: steganographic data hiding; hiding efficiency; iterative functions; Diffie-Gelman algorithm.

Published: December 2021

Tanah longsor adalah gerakan tanah yang disebabkan oleh faktor alami dan nonalami. Faktor alami dipengaruhi oleh struktur geologi daerah, jenis batuan, kemiringan lereng, dan intensitas curah hujan. Sedangkan faktor nonalami bersifat dinamis yaitu penggunaan lahan dan infrastruktur. Metode penginderaan jauh dengan citra satelit dapat digunakan untuk memetakan kawan rawan longsor. Citra satelit merupakan hasil perekaman satelit yang menggambarkan objek di permukaan bumi. Citra satelit terdiri dari beberapa band dengan panjang gelombang tertentu. Komposit band pada citra digunakan untuk mempertajam objek untuk mempermudah klasifikasi tutupan lahan. Pemetaan zonasi area rawan longsor di Kabupaten Bandung menggunakan metode pembobotan dan scoring. Pembobotan dan scoring dilakukan pada semua parameter yang menyebabkan longsor yaitu struktur geologi, jenis batuan, cutah hujan, kemiringan lereng, infrastruktur, dan tuutpan lahan hasil pengolahan citra satelit.  Hasil yang didapat menunjukan potensi tanah longsor di Kabupaten Bandung didominasi kategori sedang sampai tinggi. Pemetaan kawasan rawan longsor sangat diperlukan sebagai langkah mitigasi untuk mengurangi dampak yang diakibatkan oleh bencana tanah longsor.

Published: December 2021

Series Arc Fault is one of the disturbances of arcing jump is caused by gas ionization between two ends of damaged conductors or broken wire forming a gap in the insulator. Series arc fault is the primary driver of electrical fire. However, lack of knowledge of the disturbance of series arc fault causes the problem of electrical fire not be mitigated. Magnitude current is not capable to detect of series arc fault. Therefore, this paper proposes fast fourier transform (FFT) to detect series AC arc fault in low voltage using microcontroller ARM STM32F7NGH in real time. A cheap and high speed of microcontroller ARM STM32F7NGH can be used for FFT computation to transform signal in time domain to frequency domain. Moreover, in this paper, protection of series AC arc fault is proposed in the real time mode. In this experimental process, some various experiments are tested to evaluate the reliability of FFT and protection with various load starts from 1 A, 2 A, 3 A, 4 A in resistive load. The result of this experiment shows that series AC arc fault protection with STM32F7 microcontroller and FFT algorithm can be utilized to ensure series AC arc fault properly.

Authors: Md Ehsan Asgar  , Singholi Ajay Kumar Singh
Published: December 2021

In today’s competitive modern manufacturing sectors, there is a vital need of utter precision and rigorous processing using various manufacturing approaches that directly influences the cost and processing duration of mechanized materials in addition to the consistency of the finished products. Therefore, it’s essential to figure out the required output by adjusting the control factors of any machining techniques which resulted in optimal values of the desired outcome. In this study, machining evaluation and process optimization is carried out on volumetric extraction of material namely material removal rate (MRR), kerf obtained during the machining (KW) and surface roughness (SR) of Inconel 718 superalloy during CNC controlled wire- electrical discharge machining. Four controllable factors- pulse interval, wire speed, pulse duration and peak current are considered to investigate the influence on performance measures. Taguchi's L16 has been used to construct the set of experiments before physical experimental runs and most influencing factors have been evaluated using ANOVA. SEM images and EDXS analysis have been resorted to examine the morphology of Inconel 718. These findings assist in identifying the topography of the machined surface. Further, the optimum integration has been obtained for the best yield and recorded using grey relational analysis integrated with Taguchi’s technique (T-GRA). The unfamiliarity of the work is based on consideration of zinc coated thin wire electrode and Taguchi-Grey combined approach of modelling with four levels of experimental design.

Using Moran’s I For Detection And Monitoring Of The Covid-19 Spreading Stage In Thailand During The Third Wave Of The Pandemic
Authors: Wetchayont Parichat , Waiyasusri Katawut
Published: December 2021

Spatial distribution and spreading patterns of COVID-19 in Thailand were investigated in this study for the 1 April – 23 July 2021 period by analyzing COVID-19 incidence’s spatial autocorrelation and clustering patterns in connection to population density, adult population, mean income, hospital beds, doctors and nurses. Clustering analysis indicated that Bangkok is a significant hotspot for incidence rates, whereas other cities across the region have been less affected. Bivariate Moran’s I showed a low relationship between COVID-19 incidences and the number of adults (Moran’s I = 0.1023- 0.1985), whereas a strong positive relationship was found between COVID-19 incidences and population density (Moran’s I = 0.2776-0.6022). Moreover, the difference Moran’s I value in each parameter demonstrated the transmission level of infectious COVID-19, particularly in the Early (first phase) and Spreading stages (second and third phases). Spatial association in the early stage of the COVID-19 outbreak in Thailand was measured in this study, which is described as a spatio-temporal pattern. The results showed that all of the models indicate a significant positive spatial association of COVID-19 infections from around 10 April 2021. To avoid an exponential spread over Thailand, it was important to detect the spatial spread in the early stages. Finally, these findings could be used to create monitoring tools and policy prevention planning in future.

Published: December 2021

The article discusses the state of examination of a lethal automobile injury to a driver and a passenger in a frontal collision in the passenger compartment of class E cars.

Aim of the work. Investigate the injuries of the driver and passenger in the passenger compartment of an E class car and highlight the signs of being in the passenger compartment in the driver’s or passenger’s seat for practical use in forensic medical research.

Materials and methods. The objects of the study were 179 «Acts of forensic medical examination of corpses» and «Conclusions of an expert» on road accidents accompanied by injury and death of people obtained from the archives of the Zhytomyr Regional Bureau of Forensic Medical Examination, accompanied by the death of persons inside car. The damage to the driver and passenger in a frontal collision in the passenger compartment of class E cars was carefully considered. A set of proven reliable methods was used in the work: anthropometric, morphometric, photographic, forensic, statistical analysis.

Results. As a result of the registration of damages, the features inherent in damages received in the passenger compartment of an E-class car in a frontal collision were revealed. In particular: injuries to the soft tissues of the left leg prevailed among the front seat passengers, and not among the drivers, as is commonly believed; fractures of the bones of the lower extremities were found only in drivers; fractures of the bones of the right upper limb were observed only in front seat passengers; damage to the soft tissues of the left hand was characteristic only of drivers; the drivers had pelvic fractures on the right and left; the drivers had rib fractures on the left in combination with ruptures of the lungs on the side of the injury; the passengers had injuries to the ribs on the right, but no right-sided ruptures of the lungs were recorded.

Conclusions. It has been established that the spectrum of damage to a driver and a passenger in a fatal car injury in a frontal collision in the passenger compartment of class E cars is characterized by a sufficient variety. Fractures of the right and left lower extremities and fractures of the thoracic spine are among the features that distinguished the driver from the passenger in a frontal collision in the passenger compartment of class E cars.

The global trends in higher education highlight the growing popularity of international education shift towards innovation and better productivity that demand updated and high-quality human resources. And on the supply side, it creates pressure on families to send their children to educational institutions not only within the country but also abroad. In the context of Nepal, the trend of opening higher education institutions and students going abroad for study accelerated after 1990. Students enrolled in the country and abroad are establishing networks to work through the exchange of ideas and products in the global market. In this paper, I present the primary findings from my research on the economic impact of globalization on education in Nepal by using the supply side human resource data of student enrollment in higher education in the country and Nepali students abroad, and its impact on trade, migration, foreign direct investment and remittance to the national economy of Nepal. For this study, 20 years of secondary data of above mentioned variables have been analyzed with the help of the econometric method of causal relations. Results show a positive impact of globalization on the economy of Nepal. The findings will be useful for making policy recommendations to developing countries like Nepal to enhance education by grasping the opportunities globalization offers.

Alkıştan Gülbanga Türk Kültüründe Dua Verme Geleneği
Authors: Arslan Mustafa , Erdem Kük Didem Gülçin
Published: December 2021

Dualar, insanın aşkın bir varlığa yakarma; sığınma, af dileme, himaye talep etme, istek ve dileklerini bildirme amacıyla kurduğu kalıplaşmış sözler toplamıdır. Türk kültür evreninde duaların bireysel boyutlarının yanına, toplumsal bir boyut eklenmiş; birlikte yahut karşılıklı dualaşma geleneği gelişmiştir. Bu boyut, duaların toplu halde icra edilen ritüellerde ibadet metni olarak kullanılmalarından ve bu ritüellerde üstlendikleri işlevlerden ileri gelir. Söz konusu ritüellerde dua verme yetkisi, teolojik temsil gücü olduğu görüşü üzerinde uzlaşılan kişilerin özelindedir. Teolojik temsil gücü bulunan kimseler tarafından edilen dua, doğrudan yahut dolaylı şekilde iletilen bir talebe karşılık olarak verilir. Türk kültür evreninde, teolojik temsil gücü bulunan kişilerin yaratıcı armağanı birtakım manevi güçlerle donatıldığı görüşü hâkimdir. Yaratıcı öz kaynaklı olduğuna inanılan bu özel güçlerin toplamı, “kut” şeklinde adlandırılır. Duanın kut taşıdığına inanılan bir kimse tarafından verilmesi, inanan insanda yaratıcıya daha güçlü bir köprü ile ulaşacağı hissini doğurur. Dua veren kişinin sahip olduğu manevî güç, duada ifade edilen istek ve dileklerin yaratıcı tarafından kabul edileceği inancına kaynaklık eder. Türk kültüründe, dua verme yetkisi olan kişiler ve verdikleri dualar, tarih boyunca özel terimlerle karşılanmıştır. Ritüeli yönetme ve dua verme yetkisine sahip kimselere, “kam”, “dede”, “baba” gibi unvanlar verilmiş; onlar tarafından edilen dualar ise “alkış”, “hayırlı”, “gülbank” şeklinde adlandırılmıştır. Bu çalışmanın konusu, Türk kültüründe dua verme geleneğidir. Söz konusu geleneksel yapı, dua metinleri, icracı kadro, işlevsel boyut gibi geleneği oluşturan temel bileşenler üzerinden ele alınacak; bu sayede, mitik dönemden günümüze dua verme geleneğinin tarihsel seyri; sabit ve değişken unsurları ile birlikte aydınlatılmış olacaktır.
Augmenting the City: The Photo-Realistic Animation of a Historic Building and its influence on spatial perception and meaning

Augmented Reality (AR), defined as the holographic overlay of physical space with virtual objects in real time (Azuma, 1997), can be considered a prime example of mediatization. This development is particularly evident in the public space of the “mediatised city” (Hepp, Simon & Sowinska, 2018), being a focal point of the latest media technologies already overlaid with a multitude of AR content. But how does AR change the perception and meaning of urban space? And how can researchers capture methodically the appropriation of complex, large-scaled AR content experienced via high-tech AR glasses? To answer these questions, a historical building, that had been destroyed during the Second World War, was reconstructed as a holographic animation on a public city square. In order to resurrect this building in AR, old photographs, paintings and postcards were evaluated and used to create a virtual model in the original size and place it at its original location. The test subjects were then able to view the hologram from various different angles using AR glasses (Microsoft HoloLens 2), move freely around the square and even enter it. Combining quantitative, before-and-after questionnaires and qualitative thinking-aloud protocols, our results show that the holographic animation of a historical building can influence both the sensual-aesthetic perception and the personal meaning of a public square for city dwellers. Specifically, our test subjects perceived differences in its accessibility, coherence and aesthetics, simplicity, atmosphere and legibility. The meaning of the square was altered with regard to personal memories (= the self), typical groups of people (= others) and certain opportunities (= environment) associated with it by city dwellers.
Editorial - Animated Space

Published: December 2021

Since early days, the moving images of animated film have suggested a spatial freedom that challenges the limits of the photographic and traditional filmic space. When, in 1914, Winsor McCay drew himself onto the landscape to interact with Gertie, he was initiating a practice of expanding the space(s) we live in through the use of the animated image that lasts until today. Animation’s wide aesthetic and technical malleability, and its innate ability to suggest metamorphosis and unrest, has led its practice to cross boundaries and engage with the space beyond the limits of the traditional screen.

Performance, Programa e Cidade: Urbanismos do Chão
Authors: SILVA DA VEIGA CABRAL BARBARA
Published: December 2021

Articulando práticas artísticas e urbanísticas ao trabalho de autoras dos campos da dança, filosofia, performance e urbanismo, o artigo tem como ponto de partida revisar a colocação de Hannah Arendt (2007) e André Lepecki (2012) de que a arquitetura (o fazer cidade) é fundamentalmente anterior à política (agir cidade). A revisão parte de uma experiência que vivi em TECIDO-NÃO-TECIDO (2018), performance realizada na Barra da Tijuca. O contraponto que a performance traz é matéria para expandir as noções de política e arquitetura — reforçando que agir cidade é, de fato, fazê-la. Ao pensar arquitetura e urbanismo enquanto “políticas do chão” (CARTER, 1996), o texto termina com um breve ensaio sobre a palavra programa, comum aos campos da arquitetura e da performance, e propõe uma espécie de urbanismo imanente e do chão, cujo operador é o “programa performativo” (FABIÃO, 2013), enunciado conciso de performances, de modo a subverter a frequente determinação de usos em arquitetura e urbanismo via programas funcionais. Palavras-chave: Performance; Cidade; Arquitetura e Urbanismo; Programa performativo; Chão.

ABSTRACT

By articulating artistic and urbanistic practices with the work of authors from the fields of dance, philosophy, performance, and urbanism, the article’s starting point is to review Hannah Arendt’s (2007) and André Lepecki’s (2012) statement that architecture (to make the city) is fundamentally prior to politics (to act the city). This review is based on an experience I have lived in TECIDO-NÃO-TECIDO (2018), a performance art piece held in Barra da Tijuca, Rio de Janeiro. The counterpoint that this performance brings is used as a material to expand the notions of politics and architecture — reinforcing that acting the city is, in fact, making it. Thinking about architecture and urbanism as “ground politics” (CARTER, 1996), the text ends with a brief essay on the word program, common to the fields of architecture and performance art, and proposes a kind of immanent and ground urbanism, whose operator is the “performative program” (FABIÃO, 2013) — subverting the frequent determination of uses in architecture and urbanism via functional programs. Keywords: Performance; City; Architecture and Urbanism; Performative program; Ground.

Profundidade: uma dimensão vivida pelo corpo
Authors: Elganim Vieira Yasmin
Published: December 2021

Este artigo discute a profundidade numa direção oposta à sua objetividade. Não se trata de discorrê-la como uma habituada coordenada do espaço ou como um parâmetro referente à extensão espacial. Desdobra-se aqui a profundidade num nível subjetivo: como uma dimensão vivida pelo corpo. À luz da fenomenologia do filósofo Maurice Merleau-Ponty (1908–1961) e de sua análise dos planos pictóricos do artista Paul Cézanne (1938–1906), enunciam-se algumas considerações sobre a existência da profundidade como uma dimensão que estrutura a relação CORPO-ESPAÇO. A profundidade subjetiva se torna potencialidade para a disciplina da arquitetura ao ser responsável pelo engajamento corpóreo.
Palavras-chave: Profundidade; Fenomenologia; Merleau-Ponty; Cézanne; Relação CORPO-ESPAÇO.

Abstract
This article discusses depth in an opposite direction to its objectivity. It is not a matter of discussing it as a familiar coordinate of space or as a parameter referring to spatial extension. In this article, depth is unfolded on a subjective level: as a dimension lived by the body. Based on the phenomenology of the French philosopher Maurice Merleau-Ponty (1908–1961) and on his analysis of the pictorial planes of Paul Cézanne (1938–1906), some considerations are made about the existence of depth as a dimension that structures the body in the space. Subjective depth becomes a potentiality for the discipline of architecture by attributing plasticity to the BODY-SPACE relationship and by being responsible for corporeal engagement.

Trayectorias virtuales sexuadas, egresadas universitarias en educación virtual desde una mirada transversal.
Authors: Sepulveda Patricia Graciela
Published: December 2021

Diversos estudios, referidos a la población universitaria, mencionan el crecimiento de la matrícula femenina y al mismo tiempo su presencia en carreras que muestran relación con roles femeninos tradicionales. Carreras altamente feminizadas son la docencia, la enfermería, la obstetricia, asociadas con los roles de cuidado atribuidos a las mujeres, y resultan jerárquica y salarialmente infravaloradas.

Las trayectorias universitarias se consideran en tanto pertenecientes a personas sexuadas y teniendo en cuenta el impacto de los discursos, tecnologías y  técnicas que forjan masculinidades y femineidades específicas en cada contexto social e histórico particular.

A partir de estas ideas y a la luz de la revisión de la bibliografía nos proponemos analizar información procedente de entrevistas en profundidad realizadas a egresados y egresadas de las distintas carreras de grado que ofrece la Universidad Nacional de Quilmes en su modalidad virtual.

Este artículo se centra en los relatos acerca de las trayectorias estudiantiles femeninas desarrolladas hasta convertirse en graduadas y muestran como aún en entornos virtuales las experiencias continúan siendo sexuadas y diferentes para varones y mujeres. Si bien se entiende que es un caso particular, se pretende aportar al conocimiento de las trayectorias de aquellos que logran convertirse en graduados y graduadas universitarias.

Collaborative Governance on Ecotourism: Towards Sustainable Tourism Development
Authors: Mulyani Sri , Ahsani Retno Dewi Pramodia , Wijaya Daya Negri
Published: December 2021

This study analyses collaborative governance in sustainable ecotourism development in Magelang Regency, Central Java province. Strengthening the collaboration of the three actors is needed in developing ecotourism because it comprehensively regulates natural destinations responsible for the sustainability of natural life, economic activity, and community welfare simultaneously. To explain further the fundamental phenomena that occur in sustainable development. The goal is to create a new environmental friendly concept while also improving people's welfare, the economy, and peaceful social activities. Data were collected from in-depth interviews and observations. Interviews were conducted with 8 local government staffs, 22 ecotourism managers, and 42 communities around the destination. Then an analysis was carried out with Nvivo12+ to see the collaboration of sustainable Ecotourism governance in Magelang Regency. Three variables become benchmarks in the study: planning, implementation, and utilization. Each was measured by using six indicators. The study results showed significant local communities and businesses/private involvement in managing and developing ecotourism. Meanwhile, the local government actors need to strengthen their involvement and response in ecotourism development. So far, the response has been relatively slow and waiting for the independent development of destinations that the community has carried out. Therefore, in the future, it is necessary to strengthen collaboration to ensure effective management of natural resources in ecotourism, which can be achieved through the support and cooperation of local government agencies, businesses/private, and the communities.
Wpływ czynników agrotechnicznych na strukturę i plony nasion koniczyny białej (Trifolium repens L.)
Authors: ĆWINTAL MAREK , WILCZEK MIECZYSŁAW
Published: December 2021

W latach 2009–2011 przeprowadzono ścisłe doświadczenie polowe z koniczyną białą (odmiana Barda) na glebie kompleksu żytniego bardzo dobrego (klasa IVb), w Polowej Stacji Doświadczalnej w Parczewie. Eksperyment prowadzono w układzie split-split-plot, w czterech powtórzeniach. Czynnikami badawczymi były: przykaszanie roślin (wariant przykaszany i nieprzykaszany), rozstawy rzędów (10, 20, 30 cm), ilości wysiewu nasion (2, 4 i 6 kg · ha-1). Największy wpływ na plony nasion koniczyny białej miała pogoda podczas wegetacji, która istotnie różnicowała plony oraz większość elementów ich struktury. Duży wpływ na plony nasion miała obsada główek na 1m2 i liczba nasion w główce. Najmniej zmiennym elementem struktury plonu była masa 1000 nasion. Przykaszanie roślin istotnie zwiększało obsadę główek na 1 m2, liczbę strąków w główce i plony nasion. W zaleceniach dla praktyki rolniczej, w uprawie koniczyny białej na nasiona, należy preferować wysiew 2–4 kg · ha-1 nasion, w 20 cm rozstawie rzędów oraz przykaszanie roślin.

Przeprowadzono analizę interakcji odmian pszenżyta ozimego z latami badań. Zgodnie z metodyką przyjętą dla doświadczeń porejestrowych założono metodą pasów prostopadłych (split-block) doświadczenie polowe z 10 odmianami pszenżyta ozimego na dwóch poziomach agrotechniki – standardowym (a1) i intensywnym (a2) w trzech kolejnych sezonach wegetacyjnych w Winnej Górze. Analizowano plon ziarna, wysokość roślin oraz masę 1000 ziaren. Otrzymane wyniki z poszczególnych lat opracowano statystycznie zgodnie z metodyką dla analizy serii doświadczeń odmianowych oddzielnie dla każdego z poziomów agrotechniki. Średnie kwadraty z analiz wariancji wykazały istotne zróżnicowanie plonowania odmian pszenżyta ozimego w warunkach standardowej i intensywnej agrotechniki oraz ich zmienność w kolejnych latach. Najwyżej plonującą odmianą w standardowych warunkach agrotechniki był Trimester, a w intensywnych Algoso. Odmiany pszenżyta ozimego wykazały istotne zróżnicowanie wysokości roślin oraz masy tysiąca ziaren. W intensywnych warunkach dla masy 1000 ziaren wystąpiła interakcja odmian z latami. Większość odmian wykazała stabilność plonu ziarna, wysokości roślin i masy 1000 ziaren, a jedynie niektóre charakteryzowały się istotną interakcją z latami.
Wpływ nowego genu karłowatości (Tdw) na komponenty plonu roślin krótkosłomych odmian pszenżyta ozimego
Authors: LEŚNIOWSKA-NOWAK JUSTYNA
Published: December 2021

Wyleganie jest jedną z głównych przyczyn obniżenia plonów roślin pszenżyta. Najskuteczniejszym sposobem ograniczania tego zjawiska jest hodowla i uprawa odmian krótkosłomych z wprowadzonymi genami karłowatości. Celem przedstawionej pracy była ocena wybranych elementów plonowania roślin mieszańcowych, zawierających w swoim genomie gen Dw1 pochodzący z żyta oraz nowy gen karłowatości Tdw, który ujawnił się spontanicznie w roślinach mieszańców oddalonych pochodzących z kombinacji krzyżówkowej [(Jana × Tempo) × Jana] × Aegilops juvenalis. W pracy wykazano przydatność nowego genu Tdw do uzyskiwania nowych odmian o skróconym źdźble.
Wpływ toksycznego stężenia jonów Cu2+ na ekspresję genu MnSOD w roślinach pszenicy zwyczajnej, pszenżyta i żyta
Authors: NOWAK MICHAŁ
Published: December 2021

Podstawowym mechanizmem toksycznego działania jonów miedzi na komórki roślinne jest generowanie reaktywnych form tlenu (ROS) i spowodowany tym stres oksydacyjny. Pierwszą linię obrony żywych komórek przed aktywnością ROS stanowią enzymy klasy dysmutaz ponadtlenkowych (SOD). Wzmocnienie ekspresji genów kodujących dysmutazy ponadtlenkowe jest jednym z najważniejszych mechanizmów obronnych żywej komórki przed stresem oksydacyjnym. Cel pracy stanowiło określenie zmian poziomu transkrypcji genu kodującego mitochondrialną manganową dysmutazę ponadtlenkową (MnSOD) w warunkach stresu abiotycznego dla trzech gatunków zbóż: pszenicy zwyczajnej, pszenżyta oraz żyta. Badania wykazały, że modyfikacja ekspresji genu MnSOD stanowi jeden z elementów odpowiedzi na stres abiotyczny spowodowany przez toksyczne działanie jonów miedzi w roślinach zbożowych, jednakże charakteryzuje ją znaczne zróżnicowanie gatunkowe.

Celem badań była ocena skuteczności chwastobójczej wybranych herbicydów stosowanych na plantacji ziemniaka. Doświadczenie polowe założono metodą losowanych podbloków (split-plot), w trzech powtórzeniach. Badanymi czynnikami były dwie odmiany ziemniaka – Irga i Balbina, a także cztery sposoby pielęgnacji – trzy z użyciem herbicydów: Plateen 41,5 WG, Racer 250 EC, Sencor 70 WG oraz bez herbicydów (obiekt kontrolny). Procent zniszczenia liczby chwastów przed zbiorem bulw był zróżnicowany w zależności od sposobów pielęgnacji i wynosił od 21,1 do 55,6%. Największą skuteczność chwastobójczą stwierdzono na obiekcie opryskiwanym herbicydem Sencor 70 WG.
