Digital and traditional communication with kin: Displacement or reinforcement?
Authors: Danielsbacka Mirkka , Tammisalo Kristiina , Tanskanen Antti O
Published: August 2021

A salient question in the digital era is whether new forms of digital communication (e.g., instant messages, video calls, e-mails) have displaced or reinforced more traditional forms of communication (e.g., meeting face-to-face, contact by phone, sending letters/postcards). These opposing hypotheses, i.e., digital communication as a reinforcer versus a displacer, have attracted abundant attention among scholars; however, studies have scarcely explored these hypotheses in the context of communication among kin. Using large-scale and population-based data of 1,945 young to middle-aged (18–55 year-olds) and 2,663 older (68–73 year-olds) Finns, we tested the predictions derived from the displacement and reinforcement hypotheses in several kin dyads (parent-child, grandparent-grandchild, siblings, and aunt/uncle-niece/nephew). The results strongly supported the reinforcement hypothesis in all kin dyads, and in both younger and older adults. Associations were positive even after controlling for a wide range of potentially confounding factors. Hence, it can be concluded that digital means may reinforce rather than displace traditional forms of contact.
London superconductor and time-varying mesoscopic LC circuits
Authors: Pedrosa Inácio de Almeida , Nascimento Luciano
Published: August 2021

In this work we study the classical and quantum dynamics of a London superconductor and of a time-dependent mesoscopic or nanoscale LC circuit by assuming that the inductance and capacitance vary exponentially with time at constant rate. Surprisingly, we find that the behavior of these two systems are equivalent, both classically and quantum mechanically, and can be mapped into a standard damped harmonic oscillator which is described by the Caldirola-Kanai Hamiltonian. With the aid of the dynamical invariant method and Fock states, we solve the time-dependent Schr\"odinger equation associated with this Hamiltonian and calculate some important physical properties of these systems such as expectation values of the charge and magnetic flux, their variances and the respective uncertainty principle.
#MeToo: (Re)Shaping sexual research pedagogies through a new material autoethnographic analysis
Authors: Underhill Angela
Published: August 2021

Historically (and presently), ‘Western’ academic spaces have prioritized certain traits and bodies based on problematic, hierarchical dichotomies. These dichotomies influence ideas around normativity and superiority; for example, truth and reason were historically conceptualized as mutually exclusive from, and of more value than, emotional, subjective experiences, and the body. Such dichotomies perpetuate systems of power and oppression, and they overlook real people who could be in the room who have experienced the ‘abstract’ topic being discussed. In this paper, I extend a call for a shift to embodied pedagogical approaches to the field of human sexuality—a field that comes with heightened risks and opportunities given the nature of topics covered. Through exploring my own experiences within sexuality classrooms at various stages of my academic career, I interrogate the ‘safety’ of distancing academic identities from embodied knowledge; who is actually protected by these practices; who is more at risk? A shift in pedagogical approaches may allow students (and educators) to better engage with, and appreciate, the importance of confronting knowledge that may be emotionally challenging.

Obesity and Habitual Physical Activity Level among Staffs Working in a Military Hospital in Malacca, Malaysia
Authors: Ramli Assoc. Prof. Dr. Ayiesah
Published: August 2021

Introduction: Obesity has been recognized as a major public health concern due to lack of physical activity and a sedentary lifestyle. Methods: This cross sectional study was carried out to determine the status of body mass index (BMI) and habitual physical activity level among staffs working in Military Hospital, Malacca using Habitual Physical Activity Questionnaire (HPAQ). Results: About 120 HPAQ were distributed and only 82 responded with 23(28%) of them males and 59 (72%) females, aged between 21 to 59 (40.52 ± 9.38) years old. Anthropometry analysis showed the mean weight of male respondents was 79.48 (± 16.33) and 70.95 (± 15.66) for the females. Body mass index (BMI) for males (33.61 ± 2.82) was almost similar to females ( 33.20± 2.95).The mean waist circumference of men was 93.26 (± 10.94)cm compared to 94.03 (± 11.98)cm in the females. Following categorization of BMI, 59% (n=48) are in the obese group, 24% (n=20) are overweight and only 17% (n=14) have an ideal body weight or normal BMI. Relationship between BMI and HPAQ demonstrated strong and significant correlation coefficient for habitual physical activity at work (r = 0.775, p < 0.001), sports (r = 0.735, p < 0.05) and leisure ( r = 0.713, p < 0.001). Conclusion: The staffs working in the Hospital demonstrated poor habitual physical activity which explains for the high incidence of obesity among the staffs. This requires measures to be taken to promote a healthier lifestyle among them.

Published: August 2021

Wild diploid Arachis species are potential sources of resistance to early (ELS) and late (LLS) leaf spot diseases caused by Passalora arachidicola (syn. Cercospora arachidicola Hori), and Nothopassalora personata (syn. Cercosporidium personatum (Berk. & Curt.) Deighton), respectively. Within section Arachis, limited information is available on the extent of genetic variation for resistance to these fungal pathogens. A collection of 78 accessions representing 15 wild species of Arachis section Arachis from the U.S peanut germplasm collection was evaluated for resistance to leaf spots. Screening was conducted under field (natural inoculum) conditions in Dawson, Georgia, during 2017 and 2018. Accessions differed significantly (P < 0.01) for all three disease variables evaluated, which included final defoliation rating, ELS lesion counts, and LLS lesion counts. Relatively high levels of resistance were identified for both diseases, with LLS being the predominant pathogen during the two years of evaluation. This research documents new sources of resistance to leaf spot diseases selected from an environment with high inoculum pressure. The presence of ELS and LLS enabled the selection of resistant germplasm for further introgression and pre-breeding.

Oxidative stability is an important factor considered by those in the peanut manufacturing industry. Product stability has been shown to increase up to seven-fold when high-oleic peanuts are used. The percentage of US crop that is high-oleic continues to increase, but many producers are reluctant to grow high-oleic cultivars due to the uncertainty of the high-oleic effect on agronomic traits, such as seed germination, yield and grade. Experiments were designed and conducted to examine the effect of the high oleic trait on peanut seed germination in field plots and in the laboratory on a thermal gradient table. Genotypes used in these experiments included cultivars or breeding lines from each peanut market-type along with their near-isogenic, high oleic counterparts. Field emergence, or germination, was recorded in the field in 4 geographically different regions, as well as in the laboratory on a thermal gradient table. Thermal gradient table experimental results demonstrated a lag in germination in high oleic genotypes compared to their normal oleic counterparts in all market-types, but the effect was lowest in the runner-type pair. Results from these experiments increase the understanding of the agronomic properties of high-oleic peanut cultivars and could influence the modification of standard protocols used by state agencies to test high-oleic peanut germination for registered seed quality labeling. Furthermore, this study indicates that although producers may experience delayed germination from high oleic seed compared to low oleic counterparts, this germination lag is overcome by 21 days post-planting and does not negatively impact the agronomical performance of high oleic cultivars.

Peanut rust, caused by Puccinia arachidis Speg., is a foliar disease that plagues peanut production along with early and late leaf spots, Passalora arachidicola (Hori) U. Braun and Nothopassalora personata (Berk. & M.A. Curtis) U. Braun, C. Nakash, Videira & Crous, respectively. Rust can cause up to 80% yield losses without control and is widespread in tropical countries but is also a sporadic problem in the United States. An integrative plant management strategy with rust resistant peanut cultivars is needed to decrease dependence on costly fungicides and increase yields for farmers who cannot afford or do not have access to fungicides. Only moderate levels of rust resistance have been identified in cultivated peanut germplasm, but fortunately, high resistance to rust has been identified in wild Arachis species that can be introgressed into peanut cultivars. In this study, 16 diploid, wild Arachis species, five diploid, interspecific hybrids, 11 unique, allotetraploid interspecific hybrids, and two cultivated peanut controls were tested for resistance to rust. Resistance was evaluated in vitro by incubation time, susceptibility index (calculated based on the number of lesions of different diameters)/ leaf area, total number of lesions/ leaf area, and total number of sporulating lesions/ leaf area. All wild Arachis species tested were very highly resistant to rust, except for A. ipaënsis, the B-genome progenitor of cultivated peanut. Additionally, all interspecific hybrids and synthetic allotetraploids not produced with A. ipaënsis as a parent did not show symptoms for rust. Any of these nine synthetic allotetraploids, BatCor, BatDur1, BatDur2, BatSten1, GregSten, MagCard, MagDio, MagDur, and ValSten1 are recommended for progression to QTL mapping of rust resistance. These resistance QTLs can be pyramided into peanut cultivars to protect yields in the United States and to increase yields in tropical, developing countries for farmers that cannot afford, or do not have access to, costly fungicides.

Пестициди в підземних водах України і здоров’я
Authors: Osokina N. P.
Published: August 2021

Досліджено вміст пестицидів у підземних водах України. Методом газової хроматографії визначено стійкі хлорорганічні пестициди (ХОП): дихлордифенілтрихлоретан (ДДТ) і його метаболіти, гексахлорциклогексан (ГХЦГ) і його ізомери, альдрин, гептахлор; фосфор­органічні пестициди: метафос, карбофос, фосфамід, фозалон; фторумісні пестициди: трефлан та ін. З 1960 року по 2011 рік на сільгоспугіддя України надійшло 2 млн 85 тис. тонн пестицидів [4]. Навантаження пестицидів на ґрунти сільгоспугідь перевищило захисні властивості природного середовища, що призвело до потрапляння їх у підземну геосистему. За нашими розрахунками (за 10-річний період), середньостатистична концентрація ХОП в основних водоносних горизонтах України становить за сумою ДДТ 3,6·10⁻⁵ мг/дм³; за сумою ГХЦГ – 3·10⁻⁵ мг/дм³. Водоносний горизонт четвертинних відкладів містить на один-два порядки менше стійких ХОП, ніж глибше розміщені водоносні горизонти крейдяних, юрських і тріасових відкладень. Найбільше забруднення пестицидами виявлено у водоносних горизонтах південної і центральної України, набагато менше забруднення спостерігається у водоносних горизонтах західного, східного та північного регіонів країни. У воді свердловин одночасно виявлено до восьми сільськогосподарських забруднювачів, сумарний ефект впливу яких на організм людини не вивчений. Оцінено вплив умісту пестицидів у підземних водах на рівень онкозахворюваності населення України [7]. Потрібен контроль і сувора регламентація обсягів того чи іншого класу пестицидних препаратів під час унесення їх на сільгоспугіддя. Потрібен регулярний контроль якості підземних вод і моніторинг забруднення пестицидами підземних вод та інших об’єктів природного середовища. Результати нових аналізів щодо забруднення об’єктів природного середовища пестицидами треба порівнювати з гранично допустимою концентрацією (ГДК). Якщо рівні забруднення об’єктів природного середовища пестицидами збільшуватимуться (перевищення ГДК), то треба зменшити навантаження пестицидів на сільгоспугіддя і замінити старі пестициди на нові. Також треба сформувати збалансовану систему природокористування в контексті сталого розвитку та впровадити екологічні й інноваційні технології в сільському господарстві за допомогою сучасних механізмів національної екологічної політики.

Considered options for automating the calibration. An automatic calibration system has been developed, investigated and introduced into the production process, which is a software and hardware complex consisting of measuring instruments from the composition of the National standard of voltage unit – volt and additional modules. The automatic system was created on the basis of the modern programming language “Python” with the involvement of the experience of metrologists. A study of the results of calibration of reference voltage measures was carried out: the obtained results of the calibration of the DC voltage (assigned real value with expanded uncertainty) were analyzed in automatic and manual modes and using the “supraVOLTcontrol” system, which implements the Josephson effect. The automatic system was used in the study of the integral instability (nonlinearity) of a digital voltmeter, while a significant minimization of labor costs was obtained. The developed automatic calibration system allows to reduce labor intensity and duration of measurements, provides flexibility and ability to rebuild depending on emerging issues during research.

In the context of the needs of the leading sectors of the world economy, the current state of metrological support for measuring units of mass and volume of a liquid in a flow, mass and volume flow rates of a liquid in the range of micro-flow rates of 10–5–103 ml/min is considered. Based on the results of the analytical review, the main metrological and operating characteristics of national standards are presented. The basic principles of generating a fluid flow in national gravimetric and volumetric standards when measuring the mass and volume of a fluid by the dynamic weighing method have been determined. Constructive solutions and principles of operation of key modules of national standards are considered. Methods for filling a liquid into a storage tank and designs of storage tanks are determined, taking into account the minimization of the effect of liquid evaporation, the influence of capillary force and buoyancy. The main sources of uncertainty in measuring the mass and volume of a liquid by the dynamic weighing method and methods for minimizing these uncertainties are considered. A modified model of dynamic measurement of liquid mass flow rate is proposed, taking into account the main sources of uncertainty. A comparative assessment of the influence of sources of uncertainty on the metrological characteristics of national standards is presented.

The consistency of the results of international comparisons and the equivalence of national standards, improvement of methods for the realization of the International Temperature Scale ITS-90 main fixed points of metals freezing are considered. Two sources of uncertainty of the temperature value during realization of metals freezing fixed points have been determined. Experiments on the initiation of the inner interface between the liquid and solid phases of the metal have been carried out, the effect of the initiation conditions on the interface structure and measured temperature value in aluminum and indium fixed points cells has been investigated. The question of the correctness of the impurities influence estimates according to the laws for the only outer interface moving from the crucible walls to its center is considered. Analysis of the freezing curves obtained under different initiation conditions allowed determining the criterion for the presence of a continuous inner interface and the conditions for the formation of a single outer interface during slow crystallization of the metal without the formation of an inner interface. The obtained criteria will allow metrological institutes to choose the correct conditions for the initiation of the inner interface when using different designs of cells and heaters.

Background: The purpose of this study was to study the role of serum uric acid level in progression to preeclampsia in gestational hypertensive pregnancies.

Methods: Hospital based comparative study was conducted at Department of Obstetrics and Gynaecology, SMS medical college, Jaipur.

Results: Uric acid level was significantly higher in with PIH (6.68±0.36 mg/dl) as compared to without PIH (4.92±0.57 mg/dl). Receiver-operator characteristic curve showed relatively poor sensitivity and specificity performance (area under the curve= 1.00) of serum uric acid level at the initial presentation of gestational hypertension for predicting the progression to preeclampsia The best cut-off revealed from the curve was 6.18 mg/dl.

Conclusion: In conclusion, higher serum uric acid levels at the initial presentation of gestational hypertension may indicate heightened risk of progression to preeclampsia and development of adverse maternal/ infant conditions.

Background: Interferon-gamma [IFN-γ) is the most important cytokine in the immune system. This protein has been expressed in bacterial cells. However, bacterial cloning is not an easy task. We aimed to clone, express, and purify recombinant mouse IFN-γ and overcome problems in favor of commercial purposes. Materials and Methods: To amplify the gene product for cloning, we primarily designed two specific primers for the target gene. Following PCR amplification, the amplicon was inserted into the pET-21b[+) vector. The E. coli BL21 [DE3) CodonPlus strain was chosen for the expression of the target gene. Finally, the expressed recombinant mouse IFN-γ was assessed through the western blotting method. Results: We performed a cloning process and produced recombinant mouse IFN-γ in an optimal condition. We also noticed that monomeric protein could be transformed to a homodimeric structure which can be observed using the SDS PAGE [SDS-polyacrylamide gel electrophoresis) and western blotting. Conclusion: Experimental conditions strongly affect the large-scale cloning procedures required to be optimized in each laboratory. The expressed recombinant mouse IFN-γ described here is appropriate for commercial purposes.

The use of fibers in concrete at relatively low volume fraction has been gaining rising popularity among researchers for the recent years due to its availability, ability to enhance overall performance and cost effectiveness. Fibers are mainly classified according to their origin. Numerous researches have been carried out with natural and artificial fibers separately to elucidate its effect on the various parameters of concrete. However, a little finding is available about the comparative study among these three distinct types of fibers affecting concrete properties. In this study coconut coir, nylon thread and low-cost galvanized iron wire have been selected as natural, synthetic and steel fibers respectively. Coconut coir and nylon thread were mixed at three different percentage of 1.5%, 2.5% and 3.5% respectively by weight of cement. Steel fibre contents 1.5%, 2.5% and 3.5% respectively by weight of concrete. The results were obtained through an experimental investigation that shows the influence of natural, synthetic and steel fibers on rheological and mechanical properties of concrete. Optimum fibre content was 2.5% where steel fibre shows a maximum 17% and 30% rise in compressive and flexure strength respectively. On the other hand, fibres play a great role with its combining effect on the post cracking ductility and energy absorption of concrete.

Como um direito de todos, a comunicação e o estudo têm sido ótimos aliados no que diz respeito ao senso crítico de cada cidadão. Um ser “pensante” e com capacidade de se expor devidamente mostra ao mundo seus ideais, competências e dificuldades demonstrando a si mesmo do que é capaz. Atualmente muitas pessoas têm conhecimento de que é preciso bastante esforço para aprender de maneira autônoma, e ser assim um profissional engajado concluindo seus objetivos com sabedoria e bom senso, seguro de si e fazendo o suficiente para ter eficiência em seu trabalho, ajudando da melhor maneira possível, a fim de conquistar um futuro promissor. Este trabalho tem a finalidade de apresentar benefícios de um profissional com autonomia para assim lidar com as adversidades do cotidiano, feito a partir de pesquisas bibliográficas. Seus objetivos são entender a autonomia; compreender quem são os oprimidos na falta de autonomia para assim mudar seus posicionamentos como apenas ouvintes e recebedores de tarefas; observar motivos que levam esses funcionários a serem reclusos ou a utilizarem seus poderes de decisão em situações necessárias/solicitadas. E como objetivo geral estimular a capacidade de autonomia em profissionais que trabalham em empresas. Como conclusão observaremos o fato de que um profissional seguro torna seu trabalho mais eficiente.

General deployment of optical fibre technology commenced in the eighties. Its introduction revolutionised the telecommunications arena and has become the foundation of most telecommunication systems in use today. Optical fibres connect continents and countries, are used in core and access networks and for backhauling of mobile communication systems. The internet would barely exist without optical fibres and globalisation would hardly have seen the dawn of light. Three submarine optical cables connect Iceland to the outside world; Farice and Danice connect Iceland to Europe and Greenland Connect to America via Greenland. The optical ring around Iceland constitutes the Icelandic core network. The ring passes by nearly all villages and towns and fibre deployment in the access network has reached an advanced state. Fibre deployment in rural areas has already begun and will presumably be finished in a few years. Iceland plays a leading role in fibre deployment. In this paper, fibre utilisation in Iceland will be described, both in core and access networks. Three different architectures for fibre deployment in the access network will be described. Competition on fibre networks will also be discussed.

Climate change is expected to have impact on water supply and drinking water quality in Iceland. Foremost there are three influential weather-related factors; increase in temperature; rise in sea level; and seasonal and regional change in precipitation in both quantity and intensity. In this study international and local reports and articles were analyzed for expected impact on the water resource with emphasis on the northern and the arctic region. Water quality risk factors were analyzed based on surveillance data of the water supplies from the Local Competent Authorities. Preliminary risk assessment of landslides and flooding was performed in one surveillance area in northern Iceland.

Purpose. To increase the stability of the wellbore during its construction in unstable rocks. Methodology. To solve the set tasks, an integrated approach is used in the work, which includes critical analysis and generalization of scientific and technical achievements in combination with theoretical and experimental research. Findings. Factors influencing the stability of the borehole walls in conditions prone to rock slides and rock falls are analyzed. Expediency of using baths for strengthening the walls of wells in deposits of clay rocks, including clay shales, has been established and substantiated. A formulation of a fuel-bituminous bath has been proposed, the installation of which in a well for 78 hours makes it possible to increase the initial compressive strength of rocks, which will ensure the integrity of the borehole walls. It is recommended to use corrugated casing pipes to cover the sections of the wellbore where there is intensive crumbling and collapse of rocks. Originality. For the first time, the main factors of wall destruction have been established and a method has been developed to prevent the destruction of walls of directional wells composed of rocks prone to loss of stability under the action of drill string loads. Practical value. To combat the collapse of the walls of the well composed of rocks, prone to loss of stability, the authors suggested setting up fuel-bituminous baths in the range of complications. In case when the collapse of the walls of the well can not be prevented with a fuel-bitumen bath, it is proposed to overlap the area of collapse with the casing using advanced corrugated casing pipes with the injection of adhesive into the rock mass in the near-wellbore zone. The use of an adhesive material increases the contact area of the metal shell with the rock, which collapses increasing the stability of the borehole walls.
