Authors: Osvalde Anita , Karlsons Andis , Cekstere Gunta , Āboliņa Laura , Malecka Solveiga
Published: April 2024

Inconsistent results on the effects of humic substances (HS) on yield and nutrient status of important food crops, including oilseeds, confirm the need for further research on different HS products to match their use to actual field conditions. The aim of this study was to evaluate the effect of foliar application of commercially produced peat- and vermicompost-derived HS preparations on nutrient status and yield of spring oilseed rape (Brassica napus). The field experiment was carried out in Stende State Cereals Breeding Institute, Latvia, during the vegetation season of 2012, using the spring oilseed rape cultivar ‘Perfect’. Although foliar sprays of HS were applied during the critical stages of crop development from rapid growth to flowering, they were ineffective in improving the supply of the deficient nutrients (N, K, B, Zn, Cu) in leaves. Moreover, both tested HS products caused a decrease in Cu and B content in the seeds, which resulted in a negative trend in oilseed rape seed yield. Therefore, the conducted experiment demonstrated that foliar application of both HS preparations was ineffective to promote nutrient status and did not contribute to spring oilseed rape yield.
The Problem of Determining International Economic Sanctions in Modern Science
Authors: Butakova Y. S.
Published: April 2024

The purpose of this article is to conduct a comparative analysis of the approaches established in Russian and foreign doctrine to the definition of the term “sanctions” (in the context of “international economic sanctions”). The author examines the content of the term “sanctions”, including through their typology, and also offers his own typology of international economic sanctions based on modern sanctions regulation. The relevance of the article is investigated due to the need to form unified doctrinal approaches to the definition of international economic sanctions. At the same time, the correct application of the category under consideration is of great scientific and practical importance. For a long time, the doctrine was dominated by the approach that sanctions should be understood exclusively as sanctions of the UN Security Council. This approach is still seen as correct from the standpoint of the conceptual and categorical apparatus of international law, but at the same time, it is outdated, not reflecting modern international economic sanctions. In the course of the research, the author comes to the conclusion that through the prism of modern practice of applying unilateral sanctions in scientific research, the term “sanctions” is used synonymously with the term “unilateral restrictive measures”. The article suggests a hypothesis about the possibility of moving away from the strictly formal approach of defining international sanctions exclusively as collective coercive measures. Of particular interest is the typology of sanctions proposed in the framework of the article as reflecting modern sanctions realities.
Legal Framework for Russian Federation Leaving the Jurisdiction of the European Court of Human Rights
Authors: Ulturgashev P. Yu.
Published: April 2024

Article aims to compare the legal framework for ceasing of a state’s membership in the Council of Europe and Convention for the protection of Human Rights and Fundamental freedoms with the factual application of relevant framework in respect of the Russian Federation leaving the CoE in 2022. Analysis shows that foreseen procedures were o complied with, leading to defect actions and decision on the part of European party, and to somewhat inconsistent legal framework adopted in Russia. Lack of dialogue between the parties resulted in creation of two virtually unconnected legal realities. While the Council of Europe bodies and the Russian authorities apparently do not experience substantial adverse effects of this situation, the burden of such consequences is placed on the applicants, particularly on Russian citizens. It is assumed that very limited opportunities remain for interaction between Russian and European legal systems in terms of ensuring the rights of citizens.
Regulatory Impact Assessment (RIA) and Actual Impact Assessment (EIA) as Institutions for Improving the Quality and Effectiveness of Normative Legal Acts
Authors: Medoeva B. K.
Published: April 2024

The institutions of regulatory impact assessment (RIA) and evaluation of actual impact (EAI) contain deliberative procedures in the form of public consultations. Deliberative procedures serve as a basis for the legitimacy of legal norms, and legitimacy predetermines the effectiveness of norms. It is necessary to improve the process of public consultations, to overcome the existing problems. Institutions are options for forecasting and modeling in law. Improving the compilation of summary reports and conclusions in the framework of RIA and EAI will contribute to the quality of institutions. The importance of the categories of “purpose” and “goal-setting” in rulemaking in the context of synthesis reports is considered. The author formulates his own definition of RIA.
Analogy of Law as a Form of Judicial Precedent
Authors: Izotov Yu. G.
Published: April 2024

This study is devoted to the problem of the relationship between judicial precedent and the analogy of law. The author, studying the nature of judicial law-making, notes that law-making activity is inherent in any body of the state, if the constitution does not directly prohibit it from creating new norms. The article provides a critique of the approach to understanding the analogy of law as a way of applying law. The author notes that it is impossible to apply abstract principles directly, the court, like a legislator, must first formulate a specific provision (rule of law) on the basis of them, and then apply it. Hence it is concluded that the analogy of law is a form of judicial precedent. Normative substantiation of the possibility of Russian courts to create law requires an answer to the question about the characteristics of the judicial norm and its place in the system of sources of modern Russian law. The author comes to the conclusion that the judicial norm is causal, special and retroactive, and it can take any place, with the exception of the provisions of the Constitution of the Russian Federation, which can only be changed through the direct will of the people (chapters 1, 2, 9). The article also proposes to supplement the institution of analogy of law with norms on the mandatory request of the court considering the case to the Presidium of the Supreme Court of the Russian Federation on the creation of a judicial norm.
Threats and Challenges to The International Legal Order: Legal Problems Of Ensuring International Security in Modern Conditions (Some Conceptual Conclusions and Conclusions)
Authors: Paramuzova O. G.
Published: April 2024

This study is aimed at considering topical international legal problems of ensuring international security in the modern environment of environmental and nuclear law. Within the framework of this article, special emphasis is placed on the fact that in the current conditions of international relations, the authority of international law has been significantly undermined in recent years, which is why it is necessary to reaffirm the belief in the inviolability and necessity of the existence of the international legal system as a guarantor of the continued existence of mankind in a stable and inviolable international peace and security. The author draws attention to the fact that one of the possible ways to raise the value of general international law can be the modernization of international legal consciousness, which should be filled with a qualitatively new content, due to the need to solve problems associated with the growth of new threats and challenges to the existence of mankind.
Rethinking Legal Practice, and Its Consideration From the Position of Post-Classical Legal Method
Authors: Chestnov I. L.
Published: April 2024

The article presents the author’s position on the issue of legal practice. Today, a negative phenomenon is being discovered — the isolation of abstract, general concepts of the theory of law from the needs of legal practice. Therefore, accusations by representatives of branch legal sciences of the dogmatism of the theory of law are fully justified. This requires a rethink of legal practice. The most adequate program for clarifying the content of legal practice, in the author’s opinion, is the postclassical methodology. Signification (sign mediation), reflexivity (signification, comprehension and evaluation of the behavioral aspect), discursivity, constructability, contextuality, relativity, human dimension form the content of legal practice in the postclassical dimension. The emphasis of the post-classical research program for the study of legal practice is on the study of legal everyday life. It is formed by legal frameworks and scripts — the framework of informal norms and practices, which are the main regulators of legal behavior. The most promising approach to their study is the method of included observation within the framework of socio-cultural anthropology of law.
Legal Status of Voters and Observers in the Remote Electronic Voting System in Russia
Authors: Rzhanovskiy V. A.
Published: April 2024

The article discusses some elements in the Remote Electronic Voting system. Software used in Remote Electronic voting had significant impact on activities of traditional participants in the electoral process: voters and observers. A number of risks of interference with the electronic voting system have been identified.The author made an attempt to consider guarantees that ensure the secrecy of voting and prevent the distortion of the will of voters, which are implemented in the federal platform for Remote Electronic Voting. Moreover, additional guarantees have been identified that are not available in traditional forms of voting. One of them is the ability of the voter to check the account and invariability of his ballot in the system. It was concluded that there are technical solutions that ensure voting in accordance with the basic principles of elections. It is proposed to develop a mechanism for recounting ballots by election commissions when conducting Remote Electronic Voting.Due to the digital nature of electronic voting, the institution of observation requires additional protection mechanisms. It was concluded that electronic voting transformed the activities of the observer. The presence of a “digital trace” provides the observer with the ability to track changes in the blockchain system. The author proposed a new definition of “observer of Remote Electronic Voting”, because the definition of the observer set out in the legislation does not fully take into account the specifics of observation in Remote Electronic Voting. The new model of observation of electronic voting involves the adoption of relevant guarantees to achieve the goals of the observation.

Authors: Alzuod Mohammad Abdalkarim
Published: April 2024

The main objective of this study is to investigate talent management (TM) on innovation in Jordanian pharmaceutical companies. TM can enable employees to develop the necessary skills, knowledge, and abilities to implement innovative ideas (Ibrahim & AlOmari, 2020; Mohammed et al., 2018). The quantitative method was used to conduct this study to make the results of the study statistically significant and empirical. Data from the study has been collected by utilizing a questionnaire, which was handed out to 400 managers and employees in Jordanian pharmaceutical companies. Only, 295 retrieved questionnaires were usable for analysis. Sequentially, the Statistical Package for the Social Sciences (SPSS) software program was used to analyze of study data. The findings of the study showed that TM affected on innovation significantly and positively. Also, the results of the study statistics showed a positive significant impact of TM dimensions, identifying critical positions, competence training, development, and reward management on innovation. On the basis of the results, this study conducted some recommendations: Jordanian pharmaceutical companies should offer training and development programs to help employees build and deepen their knowledge and skills. As well as to providing incentives such as bonuses and stock options to retain high-performing employees. Hence, Jordanian pharmaceutical companies should focus on fostering a culture of innovation and collaboration that encourages employees to share their ideas and knowledge.
Effects of rattling behavior of K and Cd atoms along different directions in anisotropic KCdAs on lattice thermal transport and thermoelectric properties
Authors: Wang Yue , zhao yinchang , ni jun , dai zhenhong
Published: April 2024

We employ advanced first-principles methodology, merging self-consistent
phonon theory and the Boltzmann transport equation, to comprehensively
explore the thermal transport and thermoelectric properties of KCdAs.
Notably, the study accounts for the impact of quartic anharmonicity on
phonon group velocities in the pursuit of lattice thermal conductivity
and investigates 3ph and 4ph scattering processes on phonon lifetimes.
Through various methodologies, including examining atomic vibrational
modes and analyzing 3ph and 4ph scattering processes, the paper unveils
microphysical mechanisms contributing to the low
$\kappa_{L}$ within KCdAs. Key features include
significant anisotropy in Cd atoms, pronounced anharmonicity in K atoms,
and relative vibrations in non-equivalent As atomic layers. Cd atoms,
situated between As layers, exhibit rattling modes and strong lattice
anharmonicity, contributing to the observed low
$\kappa_{L}$. Remarkably flat bands near the valence
band maximum translate into high PF, aligning with ultra-low
$\kappa_{L}$ for exceptional thermoelectric
performance. Under optimal temperature and carrier concentration doping,
outstanding \textit{ZT} values are achieved: 4.25
(a(b)-axis, p-type), 0.90 (c-axis, p-type), 1.78 (a(b)-axis, n-type),
and 2.36 (c-axis, n-type).

Disentangling Carbon Concentration Changes Along Pathways of North Atlantic Subtropical Mode Water
Authors: Reijnders Daan , Bakker Dorothee C. E. , Sebille Erik Van
Published: April 2024

North Atlantic Subtropical Mode Water (NASTMW) serves as a major conduit
for dissolved carbon to penetrate into the ocean interior by its
wintertime outcropping events. Prior research on NASTMW has concentrated
on its physical formation and destruction, as well as Lagrangian
pathways and timescales of water into and out of NASTMW. In this study,
we examine how dissolved inorganic carbon (DIC) concentrations are
modified along Lagrangian pathways of NASTMW on subannual timescales. We
introduce Lagrangian parcels into a physical-biogeochemical model and
release these parcels annually over two decades. For different pathways
into, out of, and within NASTMW, we calculate changes in DIC
concentrations along the path (ΔDIC), distinguishing contributions from
vertical mixing and biogeochemical processes. While the mean ΔD for
parcels that persist within NASTMW in one year is relatively small at +6
µmol/L, this masks underlying dynamics: individual parcels undergo
interspersed DIC depletion and enrichment, spanning several timescales
and magnitudes. The strongest ΔDIC is during subduction of water parcels
(+101 µmol/L  in one year), followed by transport out of NASTMW due to
increases in density in water parcels (+10 µmol/L). Most DIC enrichment
and depletion regimes span timescales of weeks, related to phytoplankton
blooms. However, mixing and biogeochemical processes often oppose one
another at short timescales, so the largest net DIC changes occur at
timescales of more than 30 days. Our new Lagrangian approach complements
bulk Eulerian approaches, which average out this underlying complexity,
and is relevant to other biogeochemical studies, for example on marine
carbon dioxide removal.
Discretization of Laplacian Operator on 19 Points Stencil Using Cylindrical Mesh System with the Help of Explicit Finite Difference Scheme
Authors: Soomro Inayatullah , Mallah Rabnawaz , Muhammad Javed Iqbal  , Ahmed Waqar , Abdul Ghafoor
Published: April 2024

Abstract.

In research and technology, discretization is essential for describing and numerically assessing mathematical models. To provide promising numerical formulations with computationally efficient, mathematical models, which are frequently constructed using partial differential equations need to be discretized on curved meshes. Achieving isotropic discrete solutions is crucial for numerical evaluations of partial differential equations in many mathematical models, since it guarantees stability, correctness, and efficiency. This work revolves around the Laplacian operator, a fundamental mathematical operation in models such as Cell Dynamic simulations, Self-Consistent Field theory, and Image Processing. In this work, we utilize the explicit finite difference approach due of its correctness and computational ease. Using a cylindrical mesh structure, the Laplacian is discretized on a 19-point stencil with mixed derivatives. On cylindrical mesh systems, the numerical formulations developed here can be used to approximate solutions of partial differential equations of the first and second order. Significant isotropy, stability, and precision in computational findings for the Laplacian operator are guaranteed by the computational molecule proposed in this work. Potential applications of this formulation include the numerical analysis of different mathematical models employing the Laplacian operator.
The pros and cons of suturing the ventral hernia defect using the intraperitoneal onlay mesh technique
Authors: Jovanovic Bojan , Rancic Dejan , Rancic Ljubisa , Krstovic Miljan
Published: April 2024

Background/Aim. Laparoscopic ventral hernia surgery, including
intraperitoneal onlay mesh (IPOM), is as effective and safe as open surgery,
with a lower recurrence rate. Some surgeons advocate laparoscopic primary
fascial closure (PFC) with intraperitoneal mesh placement to reduce
recurrence rates. The aim of this study was to compare the treatment outcome
between two laparoscopic techniques: the PFC technique and mesh placement
without suture closure (IPOM technique) for defects under 4 cm in patients
with ventral hernias. Methods. The study sample was comprised of 50 patients
who underwent laparoscopic ventral hernia surgery from January 1, 2018,
until December 31, 2020. Half of the patients underwent only the IPOM
technique (group of patients without the suture), while in others, this was
preceded by the closure of the hernial ring (group of patients with the
suture). All hernias were midline and all defects were under 4 cm. The
studied groups were homogeneous according to gender and age. Comorbidities,
complications, and postoperative comfort were monitored. Results. The most
common (76%) hernias were primary, and the most common comorbidity was
arterial hypertension (28%). One (2%) patient had intraoperative bleeding,
and the most common postoperative complication was pain in 7 (14%) patients.
After a threeyear follow-up, there were 10 (20%) patients with complications
- one hernia recurred, while 9 (18%) patients died. There was no difference
in the types of occurrence of hernias, comorbidities, and intraoperative
complications. The distribution of postoperative complications differed
significantly (p = 0.007) between the groups. Pain was statistically
significantly more prevalent in patients with sutures. During the first
three months postoperatively, significantly more patients with sutures had
chronic pain (?2 = 8.140; p = 0.004). Conclusion. We recommend the
application of the PFC technique in selected ventral hernia repair cases,
although it can lead to more frequent postoperative pain (which,
fortunately, is easily treated).
Effect of “5:2 regimens”: energy-restricted diet or low-volume high-intensity interval training combined with resistance exercise on glycemic control and cardiometabolic health in adults with overweight/obesity and type 2 diabetes: A three-arm, randomized controlled trial

Published: April 2024

Objective

We aimed to examine the effects of “5:2 regimens” diet (2-day/week of energy restriction by formula diet) or exercise (2-day/week of high-intensity interval training and resistance training) intervention compared with routine lifestyle education (control) on glycemic control and cardiometabolic health among adults with overweight/obesity and type 2 diabetes.

Research Design and Methods

This two-center, open-label, three-arm, parallel-group, randomized controlled trial recruited 326 participants with overweight/obesity and type 2 diabetes, and randomized them into a 12-week of diet intervention (N=109), exercise intervention (N=108), or lifestyle education (control) (N=109). The primary outcome was the change of glycemic control measured as glycated hemoglobin (HbA1c) between the diet or exercise intervention groups and the control group after a 12-week intervention.

Results

The diet intervention significantly reduced HbA1c level (%) after the 12-week intervention (−0.72, 95% confidence interval (CI) −0.95 to −0.48), compared with the control group (−0.37, 95% CI −0.60 to −0.15) (diet vs. control: −0.34, 95% CI −0.58 to −0.11, p=0.007). The reduction in HbA1c level in the exercise intervention group (−0.46, 95% CI −0.70 to −0.23) did not significantly differ from the control group (exercise vs. control: −0.09, 95% CI −0.32 to 0.15, p=0.47). The exercise intervention group was superior in maintaining lean body mass. Both diet and exercise interventions induced improvements in adiposity and hepatic steatosis.

Conclusions

These findings suggested that the medically supervised 5:2 energy-restricted diet could provide an alternative strategy for improving glycemic control, and the exercise regimen improved body composition, although inadequate to improve glycemic control.
Micro-shear Bond Strength of an Alternative Self-etch Application of “No Wait” Universal Adhesive to Caries-affected and Sound Dentin in Permanent and Primary Teeth
Authors: Bahadır HS , Tuğutlu EC
Published: April 2024

Objective:

This study aimed to compare the micro-shear bond strength (μSBS) of caries-affected dentin (CAD) and sound dentin (SoD) in primary and permanent teeth using an alternative self-etch application of “no wait” universal adhesive.

Methods and Materials:

Flat midcoronal dentin surfaces from 72 permanent third molars and 72 second primary molars were distributed randomly into 12 groups according to the substrate SoD and artificially-created CAD (pH cycling for 14 days) and the adhesive system (GLUMA Bond5, a two-step etch & rinse adhesive, GLUMA Bond, a one-step self-etch adhesive, and Tokuyama Universal Bond, a one-step self-etch adhesive) (n=12). Bonded dentin resin discs were put through micro-shear bond strength testing after 10,000 thermocycles. The results were evaluated using two-way ANOVA and the Bonferroni test with a significance level of α = 0.05.

Results:

When compared to SoD, the etch & rinse system's test results on artificially created CAD showed a statistically significant poorer bonding performance in both permanent and primary teeth in all groups (p<0.05). While the bond strengths of permanent teeth using total-etch adhesive on sound dentin were statistically significantly higher than those using Tokuyama Universal Bond adhesive (p<0.05), there was no significant difference in sound dentin in primary teeth (p>0.05).

Conclusions:

The etch & rinse system performed the poorest of all adhesive systems on CAD. The Tokuyama Universal Bond's adhesive strength was similar in SoD and CAD on primary teeth. The use of Tokuyama Universal Adhesives can speed up restorative treatment in pediatric dentistry.
Influence of Varied Silane Commercial Brands and Adhesive Application on Bond Strength and Stability to Lithium Disilicate Glass Ceramic
Authors: Calixto ET , Kelmer VF , Komegae GH , Pacheco RR , Pini NIP , Sundfeld D
Published: April 2024

Objectives:

This study aimed to evaluate the impact of various commercial silane brands with varied chemical compositions with or without the application of an adhesive layer on the microshear bond strength and durability of a resin luting agent to lithium disilicate glass ceramic.

Methods and Materials:

Lithium disilicate glass ceramic discs (EMX, IPS e.max Press, Ivoclar Vivadent) measuring 10 mm in diameter and 3 mm in thickness were fabricated (n=240). Surfaces were etched using 5% hydrofluoric acid and randomly assigned to 10 groups based on the commercial brand of silane used (n=24): [RP] RelyX Ceramic Primer (3M ESPE); [PS] Prosil (FGM); [SA] Silano (Angelus); [SM] Silano (Maquira); [SU] Silane (Ultradent); [GL] GLUMA Ceramic Primer (Kulzer); [CB] Ceramic Bond (VOCO); [MB] Monobond N (Ivoclar Vivadent); [CP] Clearfil Ceramic Primer (Kuraray); and [DE] 2-step silane (Dentsply Sirona). Half of the EMXs (n=12) received a thin adhesive layer (+) after the silane and prior to resin luting agent, while the other half (n=12) did not receive an adhesive layer (-). For the microshear bond strength test (μSBS), four light-cured resin luting agent cylinders (1 mm in diameter) were created on each EMX surface. Half of these specimens were tested after 24 hours, while the other half were stored in deionized water for 6 months. The μSBS test was conducted using a universal testing machine (DL 500, EMIC) at a crosshead speed of 1 mm/min until failure. The obtained data underwent statistical analysis using analysis of variance (ANOVA) and the Tukey test (α=0.05).

Results:

There was significant influence of the silane commercial brand on bond strength. Notably, “universal primers” yielded lower bond strength results compared to “pure” silane solutions. Water storage had a detrimental effect on microshear bond strength for certain silane commercial brands. Additionally, the application of an adhesive layer negatively impacted bond strength results for all silanes.

Conclusions:

This study confirms the importance of both silane commercial brand and chemical composition in relation to bond strength of resin luting agents to lithium disilicate glass ceramic. Furthermore, the application of an adhesive layer may have an adverse effect on bond stability over time.
’At skynde sig langsomt’: Ungdomsliv, ventetid og pandemi
Authors: Gaini Firouz
Published: April 2024

COVID-19-pandemien havde stor indflydelse på nordiske børn og unges temporalitet i hverdagen. De unge oplevede pandemien som en lang venten (”waiting”), hvor man var nødt til at ”få tiden til at gå” på helt nye måder. Nedlukningen medførte en deceleration af tiden i forhold til, hvordan den ellers føles/opleves i børns og unges aktive hverdagsliv. Hvad skal man gøre, når man pludselig befinder sig i en venteposition, der kan vare i et par dage, nogle uger eller flere år? Hvordan skal man organisere tiden og finde en rytme i livet? I denne artikel diskuterer jeg venten som et særligt temporalt fænomen og begreb i ungdomsforskningen. Formålet med bidraget er at videreudvikle idéer om ventetid med fokus på unges hverdagsliv, tidshorisonter/tempo og fremtidsperspektiver. I artiklen, der i sin redegørelse kombinerer antropologiske studier af tid/venten med empiriske studier af børn og unge under COVID-19-pandemien, analyseres urolige og turbulente tiders indflydelse på ungdomslivets temporale rytme.
English abstract
‘Making Haste Slowly’: Youth, Waiting and the Pandemic
The COVID-19 pandemic deeply impacted the temporalities of children’s and young people’s everyday lives in the Nordic countries. Young people experienced the COVID-19 pandemic as a long wait requiring new ways of passing the time. The lockdown resulted in temporal deceleration in relation to children’s and young people’s active everyday lives. What do you do when you suddenly find yourself in a waiting position that can last days, weeks or even years? How do you organize time and find a rhythm in life? This article discusses waiting as a special temporal phenomenon and concept in youth research. The aim of the article is to develop new perspectives on waiting, focusing on young people’s everyday lives, temporal horizons, and images of the future. The article draws on anthropological studies of time/waiting, as well as empirical studies of the lives of children and young people during the pandemic. It explores a turbulent societal era in relation to the rhythm of the lives of young people.

Published: April 2024

I denne artikel undersøger vi forældres refleksioner over barndom og familieliv, som de udfoldede sig under Covid-19-pandemien i Danmark, der også var en tid præget af voksende klimabevidsthed blandt mange danskere. På baggrund af empirisk materiale fra danske familier fra middelklassen sætter vi fokus på disse forældres håndtering og forståelser af store samfundskriser som pandemi og klimaforandringer. Artiklens teoretiske vinkel kombinerer indsigter fra familieforskning om forældreskab og risikohåndtering med perspektiver fra antropologiske krisestudier. Vores analyse viser, at særligt spørgsmål som tid og nærvær i familien og barnets relation til naturen har været genstand for refleksion. Analysen belyser dermed bevægelser i kulturelle forståelser af forældreskab og barndom under pandemien.
English abstract
Family Life in Crisis and Change. The Influence of the COVID-19 Pandemic and Climate Change on Parenting Ideals in Denmark
In this article, we explore parents’ reflections on childhood and family life as they unfolded during the COVID-19 pandemic in Denmark, which was also a time marked by growing climate-change awareness among Danish citizens. Based on empirical data from Danish middle-class families, we discuss these parents’ responses to major societal crises like the pandemic and climate change. The article’s theoretical angle combines family research on parenting and risk management with insights from anthropological studies on crisis. Suggesting that reflections related to presence in family life and children’s relationships with nature are particularly prevalent, the article discusses continuity and change in cultural understandings of parenting and childhood.

I dette temanummeret får vi kunnskap om praksiser og forståelser knyttet til samfunnets ansvar for å gi barn og unge en god barndom. Endrete vilkår og konsekvenser av tiltak som velferdssystemene tar i bruk for å avhjelpe krevende situasjoner, drøftes gjennom ulike empiriske bidrag. Bidragene reiser spørsmål om hva som skjer i det uavklarte, hvilke nye erfaringer og erkjennelser som produseres i barn og unges hverdagsliv og hvordan risikoforståelser enten konstateres eller omdannes. Dette ses blant annet i lys av tiden det snakkes om og hvor det utspiller seg. Tre forhold kan trekkes frem som viktige grunnlag for utforskningen i dette temanummeret: Risikoforståelser, hverdagsliv og temporalitet.

It also offers high availability for critical applications and expedites their deployment and migration. Through cloud computing, information technology resources can be provided to end users as services via the Internet. Virtualization is one of these crucial cloud computing core technologies. We provide a thorough overview of virtualization in this paper.
Existence and Optimization of the Critical Speed for Travelling Front Solutions with Convection in Unbounded Cylinders
Authors:   , Domenech Vianney
Published: April 2024

For n > 1, we consider a reaction-diffusion equationut = Δu + α(y)∇ · G(u) + f(u), (0.2)in an unbounded cylinder Ω := R×D, where D ⊂ Rn−1 is a smooth bounded domain, with a presence of a convection term, under both Neumann and Dirichlet boundary conditions on ∂Ω. For both types of boundary condition, we consider two different forms of convection term, namely : α(y)∇·G(u) and∇ · (α(y)G(u)). The reaction term f is “monostable”. In both Neumann and Dirichlet cases, we prove that there exists a critical speed c⋆ ∈ R such that there exists a travelling front solution of the form u(x, t) = w(x1 −ct, y) with speed c if and only if c ≥ c⋆, where x1 is the coordinate corresponding to theaxis of the cylinder. The critical speed c⋆ often plays an important role for monostable problems by characterizing the long-time behaviour of the initial value problem. The existence of travelling waves for all c ≥ c⋆ is typical of monostable problems such as the prototype Fisher-KPP equation.We give a min-max formula for the speed c⋆. For both types of boundary conditions, we prove that c⋆ is bounded below by a quantity c′ which is related to a certain eigenvalue problem, associated with the linearized problem around 0. Note that under Dirichlet boundary conditions, an extra assumption is needed to ensure that c′ exists, namely, f′(0) has to be greater than the principal eigenvalue of the linearized operator. We discuss two special cases where the equality c⋆ = c′ holds. Under both Neumann and Dirichlet boundary conditions, the first special case is when G = (G1, 0, · · ·, 0), assuming the so-called KPP condition for f and that α(y)G′ 1(u) ≥ α(y)G′ 1(0), for all y ∈ D and all u ∈ (0, 1). The second case is treated only under Neumann boundary conditions : when G′ 1(0) = 0, assuming the KPP condition for f, and that α(y)G′ 1(u) ≥ 0, for all y ∈ D and u ∈ (0, 1). Note that in that case, we give an explicit formula : c⋆ = c′ = 2 p f′(0). Under Dirichlet boundary conditions, we highlight the influence of the domain D, the reaction term f and the convection term α(y)∇ · G(u) on the critical speed c⋆. In the special case where G = (G1, 0, ···, 0), using that c⋆ = c′, we use the eigenvalue problem related to c′ to establish some optimization results for c⋆.

Penyakit tungro merupakan salah satu penyakit penting tanaman padi yang disebarkan secara semi-persisten oleh vektor wereng hijau (Nephotettix virescens Distant) dan disebabkan oleh dua macam virus, yaitu rice tungro bacilliform virus (RTBV) dan rice tungro spherical virus (RTSV).  Tujuan penelitian ini adalah untuk mengetahui pola fluktuasi populasi vektor dan keberadaan penyakit tungro di Sulawesi Selatan.  Dilaksanakan di lahan petani (Pinrang, Sidrap, Gowa dan Maros) dan di Laboratorium Mikrobiologi dan Biokimia Balai Besar Bioteknologi dan Sumber Daya Genetik Bogor, sejak bulan Januari 2019 sampai Maret 2020. Survei populasi vektor dan insiden tungro dilakukan dengan teknik purposive sampling dan sistematic sampling.  Vektor tungro dikumpulkan dengan sweep net sebanyak 20 kali ayunan kemudian dihitung populasinya di masing-masing lokasi, sedangkan persentase kejadian tungro ditentukan dengan cara menghitung jumlah tanaman bergejala tungro dibagi total tanaman yang diamati per areal pengamatan dikali 100%. Keberadaan RTBV dan RTSV dideteksi dengan metode PCR. Hasil penelitian menunjukkan bahwa populasi wereng hijau (0 – 23 ekor/20 ayunan) dan persentase insiden tungro (0,01-0,13%) di Pinrang, Sidrap, Gowa dan Maros tergolong rendah.  Dibandingkan tahun-tahun sebelumnya, pola fluktuasi populasi vektor tungro cenderung berubah. Puncak populasi vektor di Pinrang dan Sidrap terjadi pada pertengahan Februari dan awal Agustus sedangkan di Gowa dan Maros terjadi pada akhir Februari dan akhir Juni.  Persentase kejadian tungro berbanding lurus dengan fluktuasi populasi vektornya.  Dari 40 sampel tanaman padi yang dikumpulkan dari empat kabupaten  di Sulawesi Selatan  hanya 4 sampel yang positif RTBV dan tidak ada sampel yang positif RTSV.

Published: April 2024

Microalgae chlorella sp. is one of the low-level plants that has many benefits and need to be harvested when they have reached optimum density. This study aims to develop a microalgae density monitoring system using the TSD-10 sensor and the ThingSpeak platform. The output voltage from the TSD-10 sensor was calibrated into microalgae density using hemocytometer and then sent wirelessly to the ThingSpeak cloud server using the ESP8266 module. A linear equation of y = –1.633 x +1421.3 was obtained from the calibration process where y is microalgae density (cell/ml) and x is analog to digital conversion (ADC) value of the TSD-10 sensor. The determination coefficient of the calibration and validation process is 0.9921 and 0.938 respectively. The measurement stability was quite good with a standard deviation ranging from 1.15×104 cell/ml to 2×104 cells/ml of culture medium. The measurement accuracy of the validation process using the RMSE (Root Mean Square Error) formula is 3.25. The time response of the sensor after power on is 5.85 s and the time it takes to display data on the ThingSpeak cloud is 16.03 s. Thus the measuring instrument developed can be said to have a fairly good performance. Keywords: Density monitoring, Microalgae, ThingSpeak platform, Tsd-10 sensor.

Published: April 2024

One-third of Crohn’s disease patients suffer from isolated small bowel lesions, 10% of whom immediately develop the stricturing form of this disease. In such patients, the diagnosis is often made only on the operating table in the setting of complications. Moreover, following small bowel resection, anastomosis strictures develop in 80% of cases. Of interest are the data of foreign authors on the decrease in the recurrences of small bowel strictures following resection in patients with maximal excision of the associated mesentery. In this connection, research on the possible role of small bowel mesentery in the pathogenesis of Crohn’s disease seems relevant. If this is the case, the optimal surgical treatment consists in performing a resection of the strictured part of the small bowel with the maximal excision of the mesentery of the affected segment and with the creation of a side-to-side antimesenteric anastomosis, excluding the contact of the anastomosis with the remaining part of the mesentery. The article presents a modern literature review on the pathogenesis of the structuring form of small bowel Crohn’s disease, its diagnostic specifics, and the selection of a treatment method, as well as original photo materials.
