Mapping displacement through lived experiences: Countermapping transit-induced gentrification in Kitchener-Waterloo, Ontario
Authors: Doucet Brian , Diwan Faryal , Turman William , Mehta Neelu , Petrovic Aleksandra
Published: December 2022

This article seeks to enhance our understanding of the role transit infrastructure plays in shaping patterns of gentrification and displacement by directly engaging with residents living along a new light rail transit (LRT) line who are affected by these processes. Displacement is difficult, if not impossible to statistically measure, yet much of the literature on transit-induced gentrification relies on quantitative analysis. Our approach is based on a collaboration between academic and non-academic partners that assembles, analyses and amplifies the experiences of marginalised residents in order to shift planning, policy and political conversations about the nature of change within our region. Through interviews with approximately fifty low-income residents living along a new LRT corridor in Waterloo Region, we analyse patterns, processes and experiences of displacement and the loss of already existing affordable housing. This information has been mapped to produce narratives that counter the dominant views which have celebrated an urban revival along the LRT corridor. Our research emphasises the need to incorporate lived experiences of displacement into central positions within the debates that make and shape cities.

Authors: Yahaya Khalid Ibrahim , Abdullahi Musbahu Abubakar
Published: December 2022

The aim of the study was to determine the antibacterial activity and phytochemical constituents of Carica papaya leaf and seeds extracts against methicillin-resistant Staphylococcus aureus (MRSA). Leaf and seed were collected and prepared using cold maceration technique. Phytochemicals screening were done. Three hundred of clinical wound samples were collected from Murtala Muhammad Specialist Hospital, Kano State. The isolation and identification of Staphylococcus aureus was done through culture on Nutrient agar and Mannitol salt agar, Gram staining, microscopic and standard biochemical tests such as (catalase, coagulase, oxidase and hemolysis test) were carried out. Cefoxitin disc diffusion test and molecular analysis was done for the detection of methicillin resistant strain of S. aureus. Evaluation of antibacterial activity of the extract against methicillin resistant strain was carried out. The phytochemical screening of leaf extract contains Saponin, Steroid, Terpenoid, Alkaloid, Flavonoid, Phenol and glycoside except Tannin and Anthraquinone in methanolic but in aqueous only anthraquinone and glycoside are not present, Seed also contains Saponin, Steroid, Terpenoid, Alkaloid and Phenol except Tannin, Flavonoid, Anthraquinone and Glycoside in both methanolic and aqueous extracts. A total of fifty six Staphylococcus aureus isolates were identified in the present study in which 8(14.3%) were MRSA and 48(85.7%) were negative MRSA. Polymerase chain reaction (PCR) analysis reveals the presence of mec A gene under 310base pairs nucleotide sequence in the positive MRSA. For the antibacterial activity leaf demonstrated antibacterial effects on 7 out of 8 tested MRSA isolates with higher activity and highest zone of inhibition of 19mm at 100mg/ml in methanolic extract. Seed evaluated antibacterial effects on 6 out 8 in methanolic extract with highest zone of inhibition of 15mm at 100mg/ml while no activity showed by aqueous extract. The calculated p value of leaf and seed is less than the table value (0.05) which is 0.00058 and 3.56E07 respectively. Based on statistical analysis there is significant.

Published: December 2022

Célkitűzés: A keratoconus ismert, ritka szövődménye, a hydrops corneae és lehetséges sebészeti terápiáinak bemutatása egy eset kapcsán. Esetismertetés: Fiatal férfibeteg jobb oldali hirtelen látásromlásának hátterében hydrops corneae igazolódott. Bal szemén keratoconusra vagy más ektatikus betegségre utaló jel nem volt. Az érintett jobb szemen kompressziós varratbehelyezéssel kombinált intracamerális 20%-os SF6 gázfeltöltést végeztünk. A cornea ödémája 1479 µm-ről 991 µm-re csökkent a posztoperatív 7. napra, majd 670 µm-re a posztoperatív 1. hónapra, és 505 µm-re a posztoperatív 6. hónapra, a kétéves kontrollon pedig 530 µm volt. A látóélesség a preoperatív kézmozgáslátásról a 6. hónapra 0,2-re, a 2 éves kontrollra 0,3-ra javult. A cornea tisztává vált, csupán paracentrálisan maradt minimális vonalas heg. Következtetés: Az akut cornealis hydrops kezelésére különböző sebészi beavatkozásokat dolgoztak ki az idők folyamán. Az általunk alkalmazott gázfeltöltés és kompressziós varratbehelyezés az irodalmi adatokkal összhangban hatékony, relatíve gyors javulást eredményező kezelési módszernek bizonyult, ami már a műtét másnapjára csökkentette az intrastromális ödémát, a cornea struktúrájának helyreállása hamar elkezdődött, és ezáltal sikerült megelőzni a cornea kiterjedt hegesedését és neovaszkularizációját.
Small Holders Farming Predictive Analysis Using Peer-
To-Peer Approach
Authors: Srikanth M. , Mohan R. N. V. Jagan , Naik M. Chandra
Published: December 2022

Farmers cultivating crops without permission from agriculture centres and
farmers might choose some crops to Grow without complete knowledge of climatic and soil
conditions, resulting in crop failures and further losses due to low rates set by middlemen
for selling the yield, leading to an increase in farmer suicides and a data scalability problem
(i.e., every time details are updated). To address the aforementioned issues, the major focus
is on establishing a suggested system that would provide farmers with crop recommendations
and yield predictions based on soil and meteorological parameters such as pH, N, P, and K
levels; temperature; rainfall; and humidity. With these circumstances, farmers can
determine which crops are the most suited as well as profitable and how much yield can be
created. Farmers may also sell their agricultural harvest directly to purchasers without the
need for a third party. We may make the farmer register to start the crop, obtain
acknowledgement from village centres, and then, after farming, re-enter the crop specifics
and amount of crop grade to accomplish data scalability. The transaction has now been
accomplished, from receiving the crop at this address to sending the harvest to a certain
warehouse. In this, we can use supervised machine learning approaches like classification
and regression to help farmers decide the best crop to grow to avoid crop failures due to
climate change, as well as to eliminate the need for a third party to sell to buyers, resulting
in direct profits to farmers and lowering farmer suicide rates.
Using Learner Feedback to Improve Teacher Practices in Materials Adaptation
Authors: SIMSEK Meliha R.
Published: December 2022

Commercial textbooks are doomed to disappoint user expectations to various extents because irrespective of origin (global/local), they are designed with an idealised classroom in mind, and their prescribed configuration probably won’t be compatible with the ever-diversifying contexts of L2 teaching and learning. Even in the case of a longtime bestseller, EFL teachers may need to customise the student-purchased materials often based on their perceived learning needs, and learner feedback is not as a rule sought on the mostly teacher-led modifications to the textbook content and procedures. Therefore, this study aimed to demonstrate how Maley’s (2011) inputs-processes-outcomes model could be used to evaluate and adapt an intermediate unit on modals of deduction, and examine how a multicultural group of 14 prep students from a major metropolitan state-run university in Turkey reacted to the teacher’s adaptive practices. Descriptive analyses of students’ activity ratings and retrospective reflections demonstrated that the addition of two scaffolded grammar tasks proved better for generating student interest and facilitating learning than replacement of another guessing game with the relatively more open and difficult task on video-based end-of-unit writing activity. Despite being independent users (B1), the participants indicated greater liking for the use of visual aids, ample practice opportunities, collaborative group work, explicit focus on grammar, and learner translations respectively. While their fewer dislikes mainly concerned video quality, activity difficulty and duration, there was almost unanimous agreement that they finally achieved to develop an increased awareness of how to use modality in English. A quick comparison of the 20-item quiz results also showed a considerable increase in their learning gains, for the mean number of correct answers more than doubled from pre- to post-test.

Published: December 2022

Cyberbullying has become more prevalent in this age due to the increased usage of electronic gadgets, the Internet, as well as the personality traits of the aggressor. The purpose of this study is to examine the effects of Dark Triad personality traits on cyberbullying behaviour among university students. The personality model adopted in this study is the Dark Triad Model, which includes Machiavellianism, Narcissism and Psychopathy. This current study used a cross-sectional quantitative research design to collect data through online questionnaires. This study utilized the 9-Item Cyberbullying Offending Scale and the 12-Item Dirty Dozen scale to gather the data. A total of 400 samples from Malaysian public university students were selected based on the convenience sampling methods. The data were analyzed using descriptive and inferential statistics through SPSS version 27. The finding shows a low level of cyberbullying behaviour among Malaysian university students. The findings also indicated that all three dark traits (i.e. Machiavellianism, Psychopathy, Narcissism) are significantly correlated with cyberbullying behaviour. Meanwhile, the regression analysis indicates that both Psychopathy and Machiavellianism significantly positive affect cyberbullying behaviour. The study contributes to the existing literature by providing evidence from the Malaysian perspective, which is a collectivistic culture in nature. Additionally, the findings provide information to the stakeholders as guidelines for future intervention and prevention programs development for cyberbullying.

Pleasure Reading: The Gains of Student Teachers of English Obtained from a Reading Journey
Authors: KARASU Onur , TUNABOYLU Oya
Published: December 2022

It is an undeniable fact that reading books is beneficial in many ways. However, a great number of potential benefits are likely to be observed when these readings are realized primarily for pleasure. This article reveals some of these benefits which were identified through a qualitative case study conducted with the voluntary participation of 37 pre-service English language teachers studying at a state university in Türkiye. The study aimed to investigate the pre-service teachers' language- and culture-related gains as well as the gains regarding personal growth from a pleasure reading experience. Qualitative data were collected through written reports that students filled out after reading the books they chose based on their individual preferences. The content analysis of the reported answers revealed that pleasure reading was most beneficial for vocabulary development regarding students' language-related gains. On the other hand, they stated that their biggest culture-related gain was obtaining the ability to understand people living in a specific time period. The students also noted that the most significant contribution of their reading experience to their personal growth was to give them a new perspective.

Authors: LAHI Besmira , NURJA Ines
Published: December 2022

As Covid19 pandemic exposed all people to be living in the pandemic, psychological concern was raised referring to vulnerable populations who could be developing psychological concerns. Therefore, during November 2022 an assessment survey was launched online aiming to screen and assess the psychological wellbeing of Albanian adults referring to their level of education and economic relatedness. Objectives of the study consist in (i) assessing the socio-demographic and economic data referring to the perceived financial expectancies and hopefulness; (ii) screen the psychological concerns related to mental health and wellbeing in relation with their economy; (iii) assess comfortability when meeting others with levels of education. Data was processed through SPSS and was analyzed using non-parametric Chi square tests and crosstabulation. Results showed that economic problems are relevant to the level of personal revenues. Sensitivity towards mental health problems is detected with the rise of the level of education. People’s capacities to resuming life just like before the pandemic has no relationship with personal revenues. Still, people report that meeting the others does not make them feel better and calmer, and makes people feel happier only in minor cases. Conclusions show that social distance could have taught people that being physically distant from others, has their own benefits.
A Surprise in the Past: The Historical Origins of the Catalan go-past
Authors: Cruschina Silvio , Kocher Anna
Published: December 2022

Crosslinguistically, the development of the verb go into a future tense is a common path of grammaticalization. In contrast, the past meaning of the go-periphrasis in Catalan is unexpected. Detges (2004) claims that the process of grammaticalization of the Catalan periphrastic perfect went from inchoative to foregrounding to past. We compare data from the Corpus informatitzat del Català antic with modern Sicilian, where a similar go-periphrasis is used with a foregrounding function that resembles that of Old Catalan. This comparison confirms a foregrounding usage but fails to support the origin in an inchoative usage. We propose that the grammaticalization from movement to foregrounding does not require an intermediate inchoative stage, but that it rather results from a modal implicature of surprise and unexpectedness that was associated with the construction. Indeed, the function of go to foreground and express surprise or noteworthiness can be inferentially viewed as movement away from the speaker’s expectations. Under this usage, Catalan go-periphrasis was employed to refer to ‘surprising’ events that took place in the past. Once this additional meaning was lost, the reference to the past was generalized beyond the implicature.

Las construcciones que omiten la causa o el agente: pasiva pronominal, impersonal, media y anticausativa
Authors: Abrines Llabrés Bartomeu
Published: December 2022

La lengua dispone de diferentes recursos gramaticales para omitir o esconder el agente o la causa de una acción. Entre estos recursos podemos mencionar la pasivización y la impersonalización de las construcciones. También las construcciones anticausativas y las medias. Todas estas construcciones comparten el hecho de ser oraciones intransitivas con un pronombre átono de tercera persona es. Ahora bien, la distinción a menudo no es clara y fácil. En este trabajo, pensando en un lector que enseña gramática en secundaria obligatoria o postobligatoria, se caracterizan sintácticamente y semánticamente estas construcciones y se señalan las principales diferencias. A continuación se propone toda una serie de actividades para trabajarlas en una clase de bachillerato desde la perspectiva de trabajo de Bosque & Gallego (2016) y el esbozo de una secuencia para aprender gramática (Camps, 2006).

Authors: KANTAR Sezai , EVİRGEN Suat , PİRHAN Yavuz
Published: December 2022

The extension of the digestive tract in the form of a blunt sac that is lined with mucosa and connected to the lumen is called a diverticulum. Diverticula can be divided into two groups as congenital (true) and acquired (pseudo) diverticula. Most of the diverticula are seen in the descending colon and sigmoid colon, and in 65% of the cases, the disease is only in the sigmoid colon. Diverticula are usually 0.5 - 1 cm in size and are numerous. İt can rarely be single and giant in size. In this presentation, we present a case of a giant sigmoid diverticulum originating from the sigmoid colon fixed to the bladder and uterocervical junction with radiological and surgical images in the light of the literature.
THE PROCEDURE OF SELECTING THE VALUES OF THE WORK CONDITION
PARAMETERS OF THE BALL-CRATERING METHOD FOR THE ASSESSMENT
OF RESISTANCE TO ABRASIVE WEAR
Authors: Osuch-Słomka Edyta , Słomka Zbigniew
Published: December 2022

In the example of the CrN coating deposited by the cathodic arc evaporation (CAE) method on two differently
prepared substrates, the procedure for selecting the values of the work condition parameters of the ballcratering
method was presented. The procedure was developed thanks to applying an individual experiment
design from Taguchi's approach and has not been used to determine the values of the parameters of the
operating conditions of the test friction node for tribological tests. The procedure, according to Taguchi,
allowed us to determine the values of the parameters for assessing the abrasion resistance of anti-wear
coatings, with the use of a much smaller number of tests, compared to the methods used so far and a repetitive
wear mechanism.
The starting point of the presented procedure was selecting the area of the permissible values of the operating
parameters, in the ball-cratering method, in which optimal values were searched for to minimise the relative
error in determining the diameters of wear marks craters. After determining the area of limit values, an
experiment plan was generated in which the variables were: load, rotational speed, minimum friction path,
and maximum friction path. The results of abrasive wear tests performed with the ball-cratering method, in
accordance with the developed test procedure for the CrN coating – were deposited on the substrate after heat
treatment and the substrate after the nitriding process had been successfully verified.
Potential and prospects of value chain development for fruits and vegetables in India
Authors: SHRUTI SHRUTI , SHARMA J P , GILLS RESHMA
Published: December 2022

Globally, India is second largest producer of horticultural produce, however, the postharvest loss estimated to be high (30-40%) and the insignificant proportion of vegetable (2%) and fruit (4%) produce are being processed. Therefore, for increasing the farmers' income, the need of the hour is to focus on beyond farm production, developing farmers' capacity for processing and linking them with market and other supporting institutions to promote efficient value chain. However, the value chain in fruits and vegetable is complex due to its perishability, high fluctuations in  demand and prices and dependence on climate conditions. Hence, the need to stress on commodity and community based processing centres, developing partnership between local processors and marketing institutions, improving competency of development officers and infrastructure development for efficient value chain promotion. The paper attempt to document the need and potential of value addition; status of actors, activities and strategic network of value chain in present scenario, the challenges of value chain at recent and strategies to improve it.

Published: December 2022

Short-term (5 years) effect of conservation agriculture (CA) practice on soil hydro-physical characteristics, soil organic carbon status and root morphology in wheat (triticum aestivum L.) was monitored under rice (Orgza sativa L.)-wheat rotation in a clay loam soil at the Indian Agricultural Research Institute, New Delhi. A small improvement in soil water content and a marginal decrease in bulk density by CA contributed in significant reduction (30-37%)in sub-surface compaction. The CA improved soil structure in the plough layer (0-15 cm) with significant increase in soil organic carbon status (27-38%). A marginal change in pore size distribution was recorded in favour of larger volume of retention pores (11-12%), in expense of macro- or drainable pore space. Steady-state infiltration, which was essentially profile-controlled, was therefore lower in the CA plots. Decrease in sub-surface soil strength and better soil water retention facilitated root growth in wheat in the sub-surface layer under CA. Results implied thatthe CA practice in rice-wheat system, although with a shorter period, led to an overall physical improvement of the most active root zone. This had positive impact on root morphology, which contributed to increase in the crop yield.

Published: December 2022

An experiment was conducted to assess the nutrients and heavy metals accumulation in spike and bulb of tuberose (Polianthes tuberosa L. cv. Prajwal) under varied wastewater-groundwater irrigations regimes at WTC farm of ICAR-Indian Agricultural Research Institute, New Delhi during three consecutive seasons in the years 2013-16. The treatments comprised wastewater irrigation schedules (0.6, 0.8, 1.0, 1.2 and 1.4 ID: CPE), conjunctive use of groundwater and municipal wastewater (at 1.0 ID: CPE) and only groundwater irrigations (at 1.0 ID: CPE) were laid-out in randomized block design with three replication. Major nutrients (N, P and K), micronutrients (Zn, Mn, Cu, Fe) and toxic heavy metals (Ni, Pb, Cd, Cr) concentration in spike and bulb parts of tuberose were analysed as per standard methods. Results indicated that significantly higher contents of macro nutrients (NPK), micronutrients (Zn, Mn, Cu, Fe) and toxic heavy metals (Ni, Pb, Cd, Cr) in both spike and bulb parts of tuberose were recorded under wastewater irrigations scheduled at 1.4 ID/CPE as compared to groundwater irrigation at 1.0 ID/CPE. Hence, irrigation with wastewater may enhanced uptake of nutrients and toxic heavy metals in tuberose due to their higher concentration in wastewater as compared to groundwater.

Published: December 2022

Mango (Mangifera indica L.) varieties, viz Amrapali and Pusa Surya were subjected to X-ray imaging for detection of jelly seed disorder. Fruits of each variety were subjected to X-rays with different combinations of voltage, current and time in a trial and error manner to obtain X-ray image. It was found that X-ray source of 48 kV, 6.5 mA, with an exposure time of 320 mA gave the best contrast images of jelly seed internal disorder. X-ray images were stored and further processed with MATLAB. Fruits which were used for X-ray imaging were also compared destructively for jelly seed disorder incidence. After comparison, it was found that both destructive and non-destructive (X-ray) images, as well as processed images, were similar. Hence, it can be concluded that X-ray imaging can be an useful method for detecting jelly seed disorder in mango.
Laboratory and field performance of manual seed drill for sowing jute and tiny seeds
Authors: SHAMBHU V B , THAKUR A K
Published: December 2022

Jute (Corchorus olitorius) is one of the bast fibre producing cash crops in the world and it is the second most important textile fibre next to cotton. Jute plays a significant role in livelihood of the resource poor small and marginal farmers in India. Jute farmers generally follow broadcast method of jute sowing where the placement of seeds at proper soil depth and uniformity cannot be attained. It becomes extremely difficult to place correct quantity of tiny seeds manually at desired depth of soil for optimum plant population due to small size of seeds. On the other hand,line sowing of small seeds like jute, mustard, sesame etc. is very much desirable to save seed as well as maintaining plant population, reduce cost of sowing, weeding and thinning. Therefore, a simple manually drawn multi-row seed drill for jute as well as small seeds of other crops was developed and evaluated in laboratory and field conditions. It ensures uniform germination and proper crop stand on one hand and facilitates other post sowing operations like weeding and thinning, fertilizer application, plant protection measure, irrigation and harvesting of jute crop on the other hand. The developed seed drill required only 75.16 N of draft for its operation which is within the capacity of an average man. It was found that the time required in line sowing for jute is only 6 man-hours/ha which is same as compared to traditional method of sowing.

The dominant weed flora were Echinocloa colona, Echinocloa crus-galli, Cynodon dactylon, Cyperus rotundus, Cyperus iria, Caesulia auxillaries and Eclipta alba. Among rice cultivars, Arize-6129 had minimum weed density (425.9 and 480.1/m) and dry weight (76.7 and 86.4 g/m2), and maximum of grain yield (4.29 and 4.12 t/ha) during both the years, respectively. Among the weed management practices, application of bispyribac sodium + azimsulfuron (25 g +35 g/ha) + 0.25% NIS (post-emergence) at 15-20 DAS proved to be most effective in minimizing the weed density, weed dry weight and increased rice grain yield (4.33 and 4.16 t/ha, respectively). Arize-6129 produced maximum net returns (`40402 and 37804/ha) and benefit: cost ratio (1.61 and 1.51) and economic efficiency (`316 and 298/ha day), respectively during both the years. Among weed management practices, application of bispyribac sodium + azimsulfuron (25 g +35 g/ha) + NIS (0.25%) was the most economical and efficient.

El presente artículo tiene como objetivo principal el análisis de las tendencias territoriales presentes en lamicrocuenca Pachacal, ubicada en el municipio de Canalete, departamento de Córdoba. Para ello, se aplicó unametodología conformada por tres fases correspondientes a igual número de objetivos específicos. En la primerafase se hizo un diagnóstico socioambiental del área estudio, relacionando factores sociales y ambientalespresentes en el lugar. Seguidamente en la fase 2, se caracterizó morfométricamente la microcuenca, y en la fase3 se generaron escenarios previsibles, deseables y posibles para la misma.Dentro de los principales resultados se tiene la situación de pobreza en la que vive gran parte de los habitantesde la microcuenca, igualmente en términos de vivienda y saneamiento son deficientes. Problemas ambientalescomo el deterioro del recurso suelo y agua, vertimiento de residuos sólidos y líquidos al cauce de la quebrada,así como la tala de árboles en sus márgenes y la quema de basuras son problemáticas existentes en el territorio.Se concluye que la situación social y económica de los pobladores de la microcuenca Pachacal es crítica, asímismo el agua que los habitantes de la microcuenca consumen, no se le aplica un tratamiento óptimo para supotabilización; sin omitir que las actividades económicas que predominan son la ganadería y la agricultura,siendo factores de presión en la transformación del territorio. Por último, se proponen unas alternativas paramejorar las condiciones socioambientales de la microcuenca

El estudio para cualquier tipo de intervención sobre el patrimonio cultural prevé una etapa preliminar dedocumentación del bien sobre el que se va a intervenir, ya sea un bien perteneciente al llamado patrimoniohistórico o un bien de interés natural - del paisaje. El trabajo presenta una metodología integrada delevantamiento tridimensional para la restitución de información tridimensional georreferenciada y conprecisión de centímetros, con el fin de contar con una restitución de métricas elaboradas para una piscinanatural en el sudeste de Italia, en el municipio de Marina Serre. La piscina natural estudiada presenta unaserie de puntos críticos, como zonas abovedadas y zonas a estudiar en el mar; para obtener un modelotridimensional completo del objeto de estudio se utilizaron instrumentos como un escáner láser terrestre(TLS), utilizado principalmente para la adquisición de las cuevas presentes en el lugar y unaaerofotogrametría desde un vehículo aéreo no tripulado, necesaria para la digitalización de la zona costeradonde está presente la piscina. Los datos han sido fusionados, en un modelo único de nubes de puntosextremadamente detallado, para luego derivar toda la información métrica necesaria a partir de esto. Losresultados obtenidos muestran que la metodología ilustrada en el estudio puede ser replicada para ladocumentación y/o monitoreo de cualquier objeto de alto interés ambiental, sin vegetación.

El cultivo de tomate (Solanum lycopersicum) presenta una serie de fitopatógenos que invaden tejidos vasculares como lo es Ralstonia solanacearum, bacteria causante del marchitamiento en estos cultivos. Los aceites esenciales, son compuestos orgánicos vegetales que tienen principios volátiles en donde generalmente son modificados cuando ocurre su proceso de extracción, su composición química de fenoles, terpenos y monoterpenos les confiere capacidades antioxidantes y antimicrobianas. Según estudios in vitro, los AE obtenidos de las plantas Thymus vulgaris (tomillo) y Origanum vulgare subsp. hirtum (orégano griego) podrían llegar a ser una alternativa de manejo y erradicación de la enfermedad de marchitez bacteriana, ya que demostraron un mejor efecto inhibitorio que los antibióticos tradicionalmente utilizados en el control de plagas como la Estreptomicina y Ampicilina, sin embargo, sugieren estudios de fitotoxicidad para evaluar si estas concentraciones afectan o no el desarrollo adecuado de la planta. Esta revisión bibliográfica presenta una alternativa sostenible con el medio ambiente a través de los Aceites Esenciales (AE) para así disminuir el impacto de fitoquímicos evidenciando el biocontrol de la bacteria. Adicionalmente se propone el uso de los AE como ayuda para el manejo y erradicación de la marchitez bacteriana causada por R. solanacearum.

Published: December 2022

Context: Rhamnetin is a naturally occurring methylated derivative of quercetin. This flavonoid is abundant in Syzygium aromaticum, Coriandrum sativum Prunus cerasus, and Rhamnus spp. Aims: To evaluate the effects of rhamnetin on HMG-CoA reductase and low-density lipoprotein receptor (LDLR) gene and protein expressions in the HepG2 hepatoma cell line. Methods: The expression of HMG-CoA reductase and LDLR genes and proteins were studied in HepG2 liver cancer cell line by PCR, Western blot, and indirect ELISA, as well as their antioxidant activity. Results: Rhamnetin was non-toxic up to 200 μM on HepG2 at 24, 48, and 72 h. Rhamnetin (25 µM) upregulated LDLR gene expression by 1.66 folds compared to 3.12 folds exerted by the well-known hypocholesterolemic drug simvastatin. Rhamnetin (100 µM) increased the expression of LDLR protein at the cell membrane, while the other concentrations produced no significant change from the control (vehicle-treated). In HepG2 cell lysate, LDLR was increased by 50 µM of rhamnetin. Also, rhamnetin increased SOD activity significantly by 100.98, 86.28, and 100.98% by the concentrations 25, 50, and 100 µM, respectively. Using the same concentrations, rhamnetin reduced H2O2 levels by 50, 67, and 76.34%, respectively. Conclusions: This study demonstrated for the first time that rhamnetin reduced HMG-CoA reductase gene expression and increased LDLR in HepG2 cells.

The purpose of the research was to identify the barriers to professional activity among disabled persons in the opinion of the disabled living in rural areas and in the opinion of their employers. We have examined 800 disabled respondents and 100 employers both from Lubelskie Voivodship. People with disabilities indicated the following reasons for inactivity: lack of jobs suitable for people with different levels and types of disability, the importance of place of residence and in this connection difficulties in getting to work; limitations resulting from the disability, inadequate education, and negative attitudes of employers towards persons with disabilities. Important was the fact that the surveyed employers also considered these factors the most crucial causes of the failure to undertake professional activity among the disabled.

The progress of civilization in Europe and many countries throughout the world has contributed to changing the way of life for entire societies. It has caused a dramatic increase in the rate of obesity. Overweight and obesity make a timeless problem. The twenty-first-century man, apart from deriving a hedonistic pleasure from eating, avoids any physical effort, which causes decreasing physical fitness and increasing of body mass. The goal of the present paper is the analysis of risk factors determining occurrence of obesity among women. An author’s survey was conducted on a sample of 604 women in Zamość county, Poland. The results were statistically analyzed, on the level of significance of p < 0,05. 22,52% of the studied group distinguished themselves with a BMI index from 25 to 30 (overweight ), whereas 7,95% had a BMI > 30, indicating obesity. The analysis of results showed that the most exposed to being overweight and obesity are women over 65 years old, with primary education or vocational training and a sedentary nature of work. Their place of dwelling had no effect on their body weight. Promoting an active way of life would be appropriate, oriented for maintaining a proper body mass. Society should be made aware of the importance of this problem and consequences of lack of knowledge on it.

Published: December 2022

In the paper the basic regional trends of marital separation which is, especially for Catholics, an alternative institution to divorce in Poland were presented. After a rapid increase at the beginning of the 21st century, the number of ordered separations started to decrease and now the relation of separations to divorces is smaller than 5%. Regionally, it is observed that the differentiation of the intensity of separations among various voivodships is decreasing, yet in more urbanized voivodships, which have a lower religiousness rate and a higher divorce rate, separations are more common.

Published: December 2022

In modern conditions, competition increases not only at the level of individual enterprises but also at the level of regions, countries and groups of countries. The problems of competitive states are insufficiently studied. This paper focuses on the problems of search tools to enhance national competitiveness through the analysis of the factors of information society development. The work consisted in identifying factors of informatization that have not been taken into calculating the indices of competitiveness in the data of the World Economic Forum. Next, the correlation coefficients between the identified factors of informatization and the main indices of competitiveness were calculated. This reveals the most significant dependencies and provides a basis for recommendations for the use of these instruments for some countries. As an example the main directions of improving competitiveness by improving factors for informatization of Ukraine and Poland were formulated.
