Psychological well-being is aligned to the ethical theory of flourishing
Authors: Coventry Petrina
Published: July 2023

Flourishing, an ethical theory founded in Stoic philosophy, centers around emotional control and learning how to live well. It connects strongly with the modern construct of psychological well-being (PWB). PWB programs are increasingly included in workplaces and factors contributing to their success can include individual motivations, accountability and responsibility, organizational support systems and design, and an understanding of mental health conditions. Anxiety, the most commonly experienced mental health condition, is an emotional state that can directly affect PWB, yet it is often neglected in research, as is the concept of who is responsible for PWB. This paper outlines a study to test the hypotheses that: emotional states can affect PWB: emotion can be considered an ethical construct; improving PWB benefits both individuals and organizations and that shared responsibility can optimize organizational PWB program outcomes. Existing information was gathered from a systematic literature review and new information was gathered from a study conducted with the Australian Institute of Health and Safety (AIHS). Mixed method research incorporated quantitative and qualitative data collection, testing occupational health and safety (OHS) practitioners’ views on anxiety, and perceptions of factors affecting success or failure of PWB programs.Findings included strong indications that: anxiety can affect PWB and impact performance and productivity; shared responsibility between employees and organizations may improve the outcomes for PWB programs; information and education around self-care, and motivational principles connected to virtue ethics can all assist individuals and organizations to assume responsibility for their role with PWB initiatives.

Published: July 2023

Sabe-se que a temperatura elevada das células fotovoltaicas é um dos principais fatores que podem afetar negativamente o desempenho dos painéis fotovoltaicos em condições reais de operação. Neste trabalho procurou-se desenvolver um modelo térmico capaz de gerar uma análise confiável da variação da temperatura de um painel fotovoltaico durante o período diurno de 4 dias característicos do ano. Para isso, como condições de contorno foram aplicados dados climatológicos da cidade de João Pessoa, Paraíba. Para desenvolver o modelo, aplicou-se o método dos volumes finitos (MFV) para uma geometria unidimensional por meio de uma análise numérica transiente. Para a modelagem, foi selecionado um painel da marca Shrap, modelo ND-220E1F. O modelo matemático desenvolvido foi executado em um código de programação no software MatLab e os resultados adquiridos foram comparados com dados de outros modelos da literatura. Além disso, realizou-se uma simulação utilizando o software Ansys, com a ferramenta Transient Thermal, e os dados adquiridos através desta simulação também foram comparados com os dados encontrados através do modelo desenvolvido neste trabalho. Por fim, foi realizada uma análise de sensibilidade paramétrica visando descobrir quais propriedades são mais influentes no modelo desenvolvido e o quanto pequenas variações nos valores destes parâmetros podem afetar o modelo. Os resultados dos dados transientes dos coeficientes adimensionais de sensibilidade foram plotados em gráficos para melhorar o entendimento de como cada parâmetro afeta o sistema. A comparação dos dados de sensibilidades dos parâmetros analisados foi feita através de uma classificação em ordem decrescente de importância.

Investigation Of 3D Effects And Free-Surface Proximity Influence On The Flow Around A Hydrofoil Using PIV Measurements
Authors: Bonnard H. , Chatellier L. , David L.
Published: July 2023

An Eppler 817 (E817) hydrofoil was studied experimentally using two dimensions two components Particles Image Velocimetry (PIV) measurements. Both statistical and time-resolved series were used to study the effect of Reynolds number and angle of attack on the flow topologies and dynamics. Vortex shedding modes were observed over a range of low chord-based Reynolds numbers 400 ≤ Rec ≤ 20000 and four angles of attack ( α = 2◦, 6◦, 12◦ and 30◦). Those Reynolds numbers are scarce documented on such hydrofoil as they are far from usual operating conditions. However, those low Reynolds numbers allowed us to observe Reynolds number based transitions of the vortex shedding modes at a given angle of attack. The data were acquired on both an extruded 2D hydrofoil and a 3D "T-shaped" hydrofoil, composed of a vertical shaft (e.g. rudder on a boat) holding the horizontal lifting surface. The latter was used to investigate the influence of both the 3D shape and surface proximity on the hydrofoil’s behaviour through three different depths, ranging from 3.5 to 0.875 chords. Additional measurements from a 6-axis loads sensor were used to characterize the loss of performance due to the free-surface proximity.
Background Oriented Schlieren Technique With Reconstruction Of Three-Dimensional Vector Fields For Pressure Measurement Of Laser Induced Underwater Shock Waves
Authors: Ichihara S. , Shimazaki T , Tagawa Y.
Published: July 2023

We propose a novel reconstruction of the three-dimensional vector field (VR) of an axisymmetric target to overcome the problems that existing background-oriented schlieren (BOS) techniques based on reconstruction of three-dimensional scalar field (SR-BOS). This approach is based on an approximate relation between the projection of the axisymmetric vector field and the reconstructed vector field. The remarkable feature of the proposed technique is the reconstruction of an axisymmetric vector field with nonzero divergence, such as the field of a laser-induced underwater shock wave. Reconstruction of 3D vector fields, such as conventional vector tomography, is usually used in the field of electromagnetics with vector fields of zero divergence, and its application to fluid phenomena has been di fficult. We have successfully applied this technique to BOS (VR-BOS) and measured the pressure fields of underwater shock waves. Using the experimental data and previous research data, the superiority of VR-BOS was clarified by comparing the measurement results of SR-BOS and VR-BOS, for example, measurement accuracy, in better convergence, less dependence on the spatial resolution of the acquired images, and lower computational cost. In particular, the fact that the measurement accuracy of VR-BOS is almost independent of resolution is expected to expand the maximum pressure values that can be measured by the BOS technique. We also used synthetic data to investigate the effect of noise on VR-BOS. If the synthetic displacement contains noise, the noise is amplified in the vicinity of the axisymmetry axis in the reconstruction distribution calculated by VT. If the distance from the axisymmetry axis is more than 1/4 of the measurement range, the measurement accuracy of the reconstructed distribution can be sufficiently guaranteed. This proposed technique can be applied fluid dynamical fields, as well as other axisymmetric targets with vector reconstruction fields in other areas, such as electromagnetics and material mechanism.

Intelligent IoT Enabled Pipeline Leakage Detection and Monitoring System Using Machine Learning Algorithm
Authors: B Manikandan
Published: July 2023

Pipeline networks are the safest transportation of oil and gas-related products that may be susceptible to failures. These kinds of failures are due to the reason of manufacturing defects, degradation of the material, environmental defects, and interference of the third party. These issues are addressed through the Internet of Things (IoT) based solutions and give promising outcomes in predicting the failures and monitoring. The IoT can combine the sensor technologies to monitor the gas flow, pressure, temperature, condition of the compressor, concentration, and other related features inside the pipeline. The leaks in the pipe are measured as a pin-sized hole that is detected by the IoT sensor with advanced technologies such as deep learning. This project proposed deep learning with a meta- heuristic approach-based model to detect leaks in pipelines through IoT sensors. The Deep Learning model called Deep Auto Encoder Neural network (DAENN) is the unsupervised model that can accurately classify the leaking and non-leaking pipeline conditions. The detection accuracy is further enhanced with the Bat Optimization algorithm (BOA) which obtained improved accuracy while leaks occur in the pipeline inside the sensor monitoring area. This observation deploys the monitoring sensors to cover the mentioned monitoring area. The proposed model can increase the system’s leak detection reliability and reduces the false alarm rate.

An Approximate Confidence Interval for the Variance of Random Effects of One-Way Analysis of Variance in the Completely Randomized Design
Authors: Alamro Reham , Al-Shiha Abdullah A. M. , Almohisen Amal
Published: July 2023

We proposed three methods to find an approximate confidence interval for the variance of the random effects for a one-way analysis of the variance model in completely randomized design. We compared the proposed methods with some other methods reported in the literature. Several criteria are used for the empirical comparisons: the mean width of the confidence interval, the variance of the width, and the coverage probability. We use Simulation and Monte-Carlo techniques to perform the comparison study. We use R language to facilitate the simulation procedures. We found that one of the proposed methods was in general superior to the others.
El agua de los campos de soja en "Distancia de rescate" (2014): decantar una Argentina agrotóxica y neoliberal
Authors: Pardo-Gamboa Christian
Published: July 2023

El presente escrito tiene como objetivo estudiar la representación del agua como agente contaminante producto de las agrotoxinas en los campos de soja en Distancia de rescate (2014) de Samanta Schweblin. Primero, se propone que agua, soja y neoliberalismo se encuentran imbricadas en toda la obra. Y segundo, observamos cómo el agua contaminada se representa en espacios herméticos, dentro de los cuales la agrotoxina no se puede contener y acaba afectando a ciertos cuerpos (mujeres, niños y niñas) por sobre otros (hombres adultos). Entonces, se realiza una síntesis de la crítica sobre la sojización y lo agrotóxico en la novela, se analizan distintos momentos donde las protagonistas se vinculan con el agua contaminada y, por último, se realiza un contraste entre los personajes femeninos y masculinos (principalmente la figura de Sotomayor).
Canon literario, escritura de mujeres y crítica cultural patriarcal en el Ecuador (2018-2022). Una teorización loca-lizada
Authors: Falconí Trávez Diego
Published: July 2023

El artículo gesta una reflexión crítica y situada sobre cómo ciertos críticos culturales ecuatorianos abordaron dos fenómenos: la publicación internacional de autoras ecuatorianas y la incorporación del análisis de género en los estudios literarios. Para ello, me centro en la discusión del canon literario (como valor, elenco textual y pedagogía) y las diversas formas en que se articuló una crítica patriarcal a través de notas de prensa, entrevistas y artículos de opinión escogidos y que aparecieron entre 2018 y 2022. A partir de la perspectiva feminista y de los estudios de género, examino estrategias retóricas patriarcales y binarias que se usaron por parte de los autores de dichos textos y que fueron poco útiles para generar diálogos productivos en el campo cultural ecuatoriano. Hacia el final explico el aporte que busco hacer desde una mirada encarnada, la loca-lización, para re-sentir el canon literario desde una perspectiva polisistémica.
La sensibilidad del agua: estética posthumana en "Semillas de cambio" y "El retorno de un lago", de Maria Thereza Alves
Authors: Juárez Vázquez Gerardo
Published: July 2023

Este artículo analiza Semillas de cambio (2009) y El retorno de un lago (2014) de la artista brasileña Maria Thereza Alves desde la perspectiva del posthumanismo propuesta por Rosi Braidotti (2019). Se postula la pertinencia de entender ambas obras de Alves como formas de memoria a partir del concepto de testimonio no humano, una propuesta amparada en una noción de estética según la cual ella es entendida como un régimen de lo sensible orientado a aumentar nuestras capacidades perceptivas. Dicho marco da la pauta para entender cómo las obras estudiadas trabajan con el agua en tanto un archivo cuyo rastro, si se emplean las herramientas adecuadas, permite enunciar desde el lenguaje del arte las huellas de las empresas colonizadoras y cómo éstas continúan operando en la actualidad.

Patients initiated on drug-resistant TB(DR-TB) treatment in 2019 in Khayelitsha, South Africa, with a loss to follow-up outcome were evaluated to better understand reasons for loss to follow-up and to determine if any had returned to care. Of a total of 187 patients, 28 (15%) were lost
to follow-up (LTFU), 24 (86%) of whom were traced: 20/24 (83%) were found when they re-presented to facilities and 8/28 (29%) were linked back to DR-TB care. People with DR-TB continue to seek care even after being LTFU; thus better coordination between different components of the healthcare
system are required to re-engage with these patients. Interventions to mitigate the socio-economic challenges of people on DR-TB treatment are needed. Many people who were LTFU and symptomatic were willing to re-engage with DR-TB care, which highlights the importance of for compassionate interventions
to welcome them back.

Published: July 2023

The national family health survey (NFHS) is a multi-round, large scale, survey conducted throughout India in a customary sample of households. It was first conducted in 1992-93, till then five surveys have been conducted. The survey was done using four types of questionnaires namely Men’s, Women’s, Biomarker, and household. The survey was funded by many international Funding agencies likeUnited States Agency for International Development (USAID), United Nations Children's Fund (UNICEF) etc. In India department of Ministry of Health and Family Welfare (MOHFW) has delegated the International Institute for Population Sciences (IIPS), Mumbai as a nodal agency for mutual support in the survey. Each survey of NFHS has two definite goalsi.ei) to anticipate data on family welfare and health for program and policy purposes and ii) to contribute an information on important family welfare and emerging health issues. Systematic review was conducted as per PRISMA guidelines, we carried out an extensive electronic search of PubMed, Google and Google Scholar to identify published studies on trends in adult height using NFHS India data. Out of a total 43 potential studies 38 were excluded and 5 relevant studies were used for final review. There is a decrease in average adult height in India. Despite of genetic, non-genetic factors like social, nutritional, and environmental plays a very important role in adult height.
Oswajanie mierci w wybranych wierszach wspczesnych poetw
Authors: Bryła Władysława
Published: July 2023

The author attempts to answer the question whether it is possible to think about death without fear. On the basis of poems by Wisawa Szymborska, Elbieta Skorupska-Raczyska and Karol Wojtyla, she concludes that the death of the closest people is accompanied by grief and longing and it can be consoled by faith in God. In overcoming the fear of ones own death a few things can be helpful, namely thinking about the inevitability of death, believing in life after death and leading a good life. Yet, mass death and the death of children cannot be tamed.
Lingwistyczny rodowd barona Kudkudaka
Authors: Duda Henryk
Published: July 2023

The article analyzes the origin of the nickname Kudkudak. It is carried by one of the supporting characters of Andrzej Sapkowskis The Witcher saga. The analysis leads to the conclusion that this onomatopeic personal name is not an individual neologism of Sapkowski. In various phonetic variants, it occurs in Borderland Polish, from where it found its way into literary texts. Its source is most likely the Ukrainian word kudkudk (), which means the voice of a hen, is an imitation of the voice of a hen. Sapkowskis source of inspiration was either the Polish language of his family on his fathers side or childrens literature, most likely Jan Brzechwas poem Kokoszka-smakoszka.

Vegetable seed production under protected and open field conditions in India: A review
Authors: SINGH BALRAJ , TOMAR B S
Published: July 2023

Vegetable crops faces tremendous challenges in the production of disease free, healthy and genetically pure seed for commercial cultivation. Conventional practices of seed production in open fields' faces common problems like lack of sufficient isolation, insects, diseases and a virus free environment. Compared to conventional practices, protected cultivation can deliver higher seed yield with better quality. Insects and viruses are the most devastating problems for quality seed production in most of the vegetable crops in open fields, and if the insect vectors are checked by using protected structures this problem could be solved with less application of pesticides. An innovation applicable in a very practical manner is always likely to get popularity to the assumed potential resulting in significant profit to the stakeholders. Seed production under protected conditions is a best example of it. A decade ago, research on seed production under protected conditions was initiated in India and tremendous work has been carried out to standardize the technology, i.e. for quality seed production realizing the various biotic and abiotic stress problems encountered in open field seed production programmes. The present review provides comprehensive information on significant research work done in India in hybrid seed production of vegetables under various protected and open field environment. This concept has shown significant results not only in quality seed production but also in increasing the per unit seed yield in different vegetables. The protected cultivation models has proved to be highly economical and profitable with limited resources and man power to provide best quality seeds of numerous vegetables cultivated in India and across the globe.

Published: July 2023

The functional linkages of producers with different systems and within the system in the form of backward and forward linkages in production process involve the investments in the form of transactional costs. Farmers’ collective action for better production in the form of self help groups (SHGs), farmers’ interest groups (FIGs), marketing associations, producers associations, co-operatives etc. have contributed in maximizing the input-output ratio and ultimately increasing the benefit of producers. The present study was undertaken to find out the motivating factors to join association and the benefits accrued as a result of joining such producers’ federation namely TAMAFED (Tamil Nadu Mango Growers Federation) dealing with mango crop in Tamil Nadu state of India. A set of sixty member and sixty non-member farmers were selected from the six villages of the three districts of the state. The Logit analysis revealed that education, economic benefit and area under mango cultivation were the major determinants of motivation to join TAMAFED. As a measure of economic gain, transactional output cost due to sale of harvested produce was two and half times less for members compared to non-members. The comparative analysis shows that mean transactional input cost per hectare was found to be significantly lower for members than non-members. The members of TAMAFED gained social and economic benefits and the costs incurred on input and output transactions were quite low ultimately adding to the benefit. As such, it may be recommended that organization of farmers on commodity basis in the form of similar federations may be promoted for socio economic gain of the farmers.

Published: July 2023

A field experiment was conducted over two consecutive rainy (kharif) and winter (rabi) seasons of 2013–14 and 2014–15 at IARI, New Delhi; to evaluate the direct and residual effects of three sulphur (S) levels (0, 20 and 40 kg S/ ha), four zinc (Zn) levels (0, 2.5, 5 and 7.5 kg Zn/ha) and two zinc biofertilizer levels (control and zinc biofertilizer seed treatment) on the performance of groundnut (Arachis hypogaea L.)–wheat {Triticum aestivum (L.) emend. Fiori & Paol.} cropping system (GWCS). Results pertaining to direct effects on system productivity and residual effects on performance of wheat have been included in this paper. Across the seasons, residual effects of 40 kg S/ha and 5 and 7.5 kg Zn/ha were perceptible on the grain and straw yield, economics, energetics, and S and Zn uptake in wheat crop. Based on 2 years’ average, wheat grain yield increased by 4.9%, net profit by ` 4 200/ha and energy returns by 8.3×103 MJ due to residual effect of 40 kg S/ha over control. On an average, application of 5 and 7.5 kg Zn/ha to groundnut led to increased wheat grain yield by 4.1 and 4.5%, net profit by ` 3 300 and ` 4 000/ha, and energy returns by 6.1×103 and 7.8 ×103 MJ, respectively due to residual fertility. With successive increase in Zn–levels to groundnut, a significant Zn–enrichment of wheat grain and straw was also observed in the current study. However, no residual effect of Zn–solubilizer was noticed on wheat crop. On an average, application of 40 kg S/ha and 5 kg Zn/ha was found to enhance the GWCS system productivity by 16.8 and 12.2% over control, respectively; besides respective significant higher economic–efficiency of ` 299 and 287/ha/day. Perceptible variations were also noticed in the system productivity and economic–efficiency following Zn–solubilizer application over the control. Overall, it is concluded that application of S @ 40 kg/ha and Zn @ 5 kg/ha to groundnut had marked residual effect on wheat productivity, profitability, energy dynamics besides Zn biofortification in wheat. The direct application of S @ 40 kg/ ha and Zn @ 5 kg/ha also led to significant enhancement in groundnut pod yield, system productivity, system production- efficiency and system economic-efficiency as well, indicating that S @ 40 kg/ha and Zn @ 5 kg/ha are sufficient enough to meet the S and Zn requirement of GWCS.

Elephant foot yam [Amorphophallus paeoniifolius (Dennst.) Nicolson] is an important tuber crop grown in many parts of India for its starchy corm and the average yield of this crop is far below the potential productivity of 100 tonnes/ha. One of the reasons attributed to the lower yield is the imbalanced application of essential plant nutrients. Site specific nutrient management (SSNM) is the application of plant nutrients based on the soil and crop need, yield target and developed with the aid of models such as QUEFTS. This paper gives the result of four year study conducted to calibrate and validate the QUEFTS model for elephant foot yam cultivation and the development of SSNM zonation maps and secondary and micronutrient fortified customised fertilizers for the crop in major growing environments of India. Data collected from different field experiments conducted in major elephant foot yam-production regions of India during 1968 to 2011 were used to calibrate the model. The derived parameters of minimum and maximum accumulation of N (130 and 460), P (900 and 2100) and K (100 and 170) are proposed as standard borderline values in the QUEFTS model for elephant foot yam. A linear increase in corm yield was suggested by the model with N, P and K uptakes of 3.97, 0.71, and 7.05 kg N, P and K/1 000 kg corm. The average NPK ratio in total plant dry matter was 5.56:1:9.88. Based on these results, the model was calibrated using historical data as well as by conducting field experiments. It can be observed that fertilizer best management practices by SSNM resulted in an average actual corm yield of 33.45 tonnes/ha, whereas, the model predicted a yield of 35 tonnes/ha. The results of the study showed good agreement between predicted and measured corm yields during the four years, which indicated that the calibrated model can be used to improve NPK fertilizer recommendations for elephant foot yam in India. Based on the results and using soil fertility maps and agro ecological unit maps, SSNM zonation maps and secondary and micronutrient fortified customised fertilizers were developed for major elephant foot yam growing environments of India.

Macronutrient delivery to plants, particularly nitrogen, is problematic because of losses occurring during fertilization. Currently, nanotechnology is being considered as a solution to improving nutrient use efficiency. In this study, we report the synthesis and plant uptake of two plant nutrient nanocomposites based on urea coated hydroxyapatite (UHA) and potassium encapsulated into (i) a nanoclay, montmorillonite (MMT) or (ii) cavities present in Gliricidia sepium stem resulting in a wood chip containing macronutrients. Soil leaching behaviour, efficacy and plant uptake of the nutrients were tested in a pot experiment using Festuca arundinacea during a period of 60 weeks. Two nanocomposites displayed slow release behaviour particularly for nitrogen, in soil leaching tests compared to the conventional formulations. Both nanoformulations displayed efficient plant nutrient uptake highlighting the improved nutrient use efficiency.

An electronic experimental set-up was developed to evaluate three seed-metering mechanisms, viz. slanting, semi- circular and rectangular shape for three paddy varieties and to investigate the influence of the selected levels of variables, viz. forward speed, cell shape and inclination of seed-metering plate on performance parameters of seed- metering. Mean seed spacing, miss index and seed damage were found to increase with increase in forward speed and angle of inclination while multiple index decreased with increase in forward speed and angle of inclination for all metering plates tested. Precision decreased with increase in forward speed and with increase in angle of inclination, it increased initially up to optimum value and then decreased. The mean seed spacing of 14.8 cm close to theoretical seed spacing of 15 cm, highest quality feed index of 88.1%, lowest miss index of 6.1% and minimum seed damage of 0.38% were observed in slanting type metering plate at an angle of 35º with the horizontal and at a forward speed (belt speed) of 2 km/h. Hence, for design of precision paddy planter, the optimum parameters, like slanting type metering plate with angle of inclination 35º and forward speed of 2 km/h can be used to achieve best results.

An experiment was conducted during winter (Rabi) season 2009-2011 to study the effect of sulphur fertilization on garlic (Allium sativum L.), potato (Solanum tuberosum L.) and onion (Allium cepa L.) on alluvial soil at Bichpuri, Agra (Uttar Pardesh) . The treatments comprised five levels of S (0, 15, 30, 45 and 60 kg/ha) were evaluated in randomized block design with four replications. The results revealed that the application of sulphur up to 45 kg/ha significantly increased the yields and dry matter production of vegetable crops, whereas, at higher sulphur level (60 kg/ha) the yield tended to decrease in potato. The magnitude of mean response to sulphur application differed from crop to crop and were recorded as onion (30.2 %) > garlic (22.5 %) > potato (17.0 %) over control. Sulphur application progressively increased the uptake of S in vegetable crops. A phenomenal increase in N, P and K uptake, except of Zn, was recorded in vegetable crops due to increasing levels of S up to 60 kg/ha. The maximum removal of N, P and K was recorded with potato tubers while those of S and Zn with onion bulbs. The higher amounts of protein and protein yield were recorded in potato followed by onion and garlic. Sulphur application significantly improved the content and yield of protein in these vegetable crops over control and maximum values were recorded at 60 kg S/ ha. Garlic and onion gave maximum net returns and B:C ratio with 60 kg S/ha and potato at 45 kg/ha. The apparent recovery of sulphur was influenced by S levels with maximum at 45 kg S/ha, except potato where maximum (36.3 %)apparent recovery was recorded with 15 kg S/ha. Better sulphur use efficiency in garlic, onion and potato was obtained with 30 kg S/ha. The sulphur use efficiency decreased with its increasing levels and minimum use efficiency was recorded with 60 kg S/ha application.

This article aims to find out how the concept of teacher and student is according to the Qur'an and Hadith. The framework used to analyze this theme is a thematic study based on the discussion on the arguments of the Qur'an and Hadith in understanding the meaning of words and the essence of the concept of the teacher and student itself. The discussion that will be raised is the understanding of teachers and students from the perspective of the Qur’an and hadith. Because education is an activity that involves at least 2 individuals who are interrelated and interact with each other, which we know as teacher and student. Teachers are all those who try to improve others Islamically. They can be parents (fathers and mothers), uncles, siblings, neighbours, religious leaders, community leaders, and the wider community. As for students, they are people who want to get knowledge, experience and a good personality to equip their lives so they can be happy in this world and the hereafter by studying earnestly.

A hajtatott paprikán károsító tripszek (nyugati virágtripsz, Frankliniella occidentalis, dohánytripsz, Thrips tabaci) ellen hatékony biológiai védekezési módszer a kereskedelmi forgalomban lévő Orius ragadozó poloskák alkalmazása. Az őshonos Orius fajok azonban spontán is betelepülhetnek a külső környezetből a termesztő-berendezésekbe. Kutatásunk során azokat a tényezőket vizsgáltuk, amelyek befolyásolhatják az Orius fajok előfordulását a tájban; azt feltételeztük, hogy ha nem véletlenszerűen fordulnak elő, akkor ott gyakoribbak, ahol több a féltermészetes élőhely. Kiegészítő módszertani vizsgálatot is végeztünk, melynek alapján a bürköt (Conium maculatum L.) megfelelőnek tartottuk az Orius populáció táji léptékű vizsgálatához. Megállapítottuk, hogy a biológiai növényvédelem szempontjából jelentős O. niger a meleg 2007-es évben a tájnak azon a részén csoportosult, ahol kevesebb féltermészetes terület volt. Mindebből arra következtettünk, hogy a telelést követő tenyészidőszakban az extenzíven művelt mezőgazdasági táblák nyújtják a fő táplálkozási és szaporodási lehetőséget, így ezek élőhely-minősége is meghatározó, annak ellenére, hogy a féltermészetes területek jelentősek az Orius fajok számára, mivel ott vészelhetik át azokat az időszakokat, amikor a mezőgazdasági táblák nem megfelelő élőhelyek számukra (pl.: téli időszak, betakarítás, talajművelés, kaszálás). A termelők szempontjából fontos, hogy az Orius fajok betelepülésére elsősorban a meleg évjáratokban lehet számítani, illetve, hogy az extenzíven művelt területek közelsége előnyös.

Régóta ismert jelenség, hogy a Lamiaceae családba tartozó kakukkfüvek (Thymus spp.) könnyen hibridizálódnak egymással. Adott populáción belül eltérő alak-változatok is jelen lehetnek, továbbá különféle illóolaj-összetétellel rendelkező kakukkfű populációk egy termőhelyen való előfordulásáról is beszámoltak (LOZIÉNE 2006, RADONIć et al. 2008). Megfigyeléseink ezen tényekkel nagyrészt egybehangzóak. Célunk volt, hogy a vizsgált vadkakukkfű populációk kémiai diverzitása mellett felmérjük azok morfológiai változatosságát. A vizsgált populációk termőhelyei a következő tájegységekhez tartoztak: Bakony, Balaton-felvidék, Budai-hegység, Bükk, Cserehát, Gerecse, Gödöllői-dombság, Mátra, Pilis, Somogyi-dombság, Velencei-hegység, Vértes, Visegrádi-hegység és Zempléni-hegység. A 39 termőhelyen történt felvételezéseink során igazoltuk, hogy a T. glabrescens, Willd. és a T. pannonicus, All. ruderális termőhelyeken is előforduló, kozmopolita, tágtűrésű, pionír növényfajok, melyek a termőhelyek alapkőzetének és talajjellemzőinek széles variációit is tolerálják. Megállapítottuk továbbá, hogy a citromolajos kemotaxon megjelenése nemcsak a T. pulegioides-nél gyakori, hanem a T. pannonicus-nál is, míg a T. glabrescens-nél − a szakirodalommal egyezően − nem jellemző (Simon 2000). A feldolgozott herbáriumi anyag alapján bebizonyosodott, hogy a legnagyobb morfológiai variabilitást a T. glabrescens és a T. pannonicus mutatja. A magas kakukkfű levélhosszúság/levélszélesség aránya (1,25−7,00) igen változatosnak adódott, ami azt jelzi, hogy igen heterogén alakú levelei lehetnek, de többnyire a lándzsás levéllemez a jellemző. Megállapítottuk, hogy a T. glabrescens és a T. pannonicus is pompázhat a még le nem írt virágszínekben is. A szakirodalom adatait kiegészítve igazoltuk, hogy a T. pulegioides egyedek nemcsak a száréleken lehetnek szőrösek, hanem 2−2 szemben lévő oldalán alternálva és a szár minden oldalán egyaránt. A levélzet általában mindhárom fajnál a teljes száron oszlik meg, kivétel a magas kakkukkfű, ahol több populációban csak a szár felső részére összpontosult. A levélzet sűrűsége a magas és közönséges kakukkfűnél sűrűnek, vagy közepesnek adódott, míg a hegyi kakukkfűnél a ritka és a közepes levélsűrűség volt jellemző. A T. pannonicus-nál az egyes virágörvök között általában sűrűn fedőszörös, fehéres-molyhos volt a szár, míg ez kevésbé volt jellemző a T. glabrescens és a T. pulegioides egyedeinél.

Az alföldi folyók árterei, illetve az ártereken található holtágak rendkívüli táji, ökológiai értékek. A területek a génmegőrző funkción túl tájesztétikai, turisztikai és víztározási szereppel is bírnak. Ahhoz, hogy a holtágak képesek legyenek ezen funkciók ellátására, szükség van állapotuk folyamatos monitorozására, illetve szükség esetén javítására. A holtágak környezeti állapotát többek között vizük és üledékük minőségének elemzésével tudjuk felmérni. Kutatásunk során egyes Alsó-Tisza-vidéki és Hármas-Körös menti holtágak állapotát értékeltük vizük és üledékük minősége alapján, majd pedig a Hakanson-féle ökológiai kockázat indexszel megbecsültük az egyes hullámtéri holtágak ökológiai állapotát. Hakanson-féle kockázati index alapján az Alsó-Tisza-vidék hullámtéri holtágai mérsékelt potenciális ökológiai kockázatúak, míg a Hármas-Körös menti hullámtéri holtágak az alacsony potenciális ökológiai kockázati osztályba sorolhatók.
