Published: December 2023

The glass was prepared by the standard melt-quenching technique. The
crystallization of powder glass from the system Li2O-Al2O3-GeO2-P2O5 was
studied. The investigations were performed under non-isothermal and
isothermal conditions using the AAS, DTA, XRD and FTIR methods. The aim of
this research was to study the ease of glass formation, crystallization and
crystal structure of obtained phases. The results showed that the glass
crystallizes by primary crystallization. LiGe2(PO4)3 was formed as the
primary phase, until detectable traces of GeO2 were formed as secondary. The
influence of particle size of the glass powder samples in the range 0-1 mm
on the temperature of the DTA crystallization peak, Tp, the peak height
(dT)p and the parameter Tp2/(DT)p was studied. It was demonstrated that for
the particle size in the range of 0.05-0.35 mm surface and volume
crystallization were significant, while the particle size >0.35 mm according
to the volume crystallization was dominant.
Numerical simulation of thermal performance of cold plates for high heat flux electronics cooling
Authors: Song Hanlin , Zheng Meng , Ma Zheshu , Li Yanju , Shao Wei
Published: December 2023

High heat flow density electronic components need cooling plates with strong heat exchange capacity to maintain temperature balance. To obtain better cooling performance, four different flow channel types of cooling plates are designed, including an S-type channel, Z-type channel, mosaic channel and double-layer channel. The maximum temperature of the cooling plate, outlet temperature and pressure drop under different working conditions and coolant are analyzed by numerical simulation. The simulation results show that the double-layer channel design can effectively enhance the heat transfer effect of the cooling plate and reduce the pressure drop. The maximum temperature of the cooling plate of the double-layer flow channel is 6.88 ?C lower than that of the Z-type flow channel. Moreover, increasing the inlet flow rate and lowering the coolant inlet temperature can improve the cooling performance of the cold plate, but increasing the inlet flow rate will lead to an increase in the pressure loss of the cold plate. When the coolant of the dou?ble-layer channel cooling plate is 20% ethylene glycol-water solution, the cooling performance is better than the other three coolants. Other channel cooling plates perform better with water as the coolant.
Experimental investigation on the heat transfer performance of Galinstan liquid metal driven by electromagnetism
Authors: Li Fajing , Zhang Zhongkai , Xie Sanmu , Chen Peizhu
Published: December 2023

Liquid metals have excellent heat transfer performance and unique electromagnetic characteristics, providing new visions for cooling the high speed motorized spindle shaft. Liquid metal can be driven by the magnetic field of the motor stator to induce current with no dynamic seal problem. In the present study, a shaft cooling structure of a motorized spindle with Galinstan liquid metal as the working fluid was designed and the heat transfer performance of the designed structure was investigated experimentally. The obtained results at the rated speed and rated current show that the induced voltage in the wire installed on the shaft reaches 1.2 V, which can circulate the liquid metal in an 8 mm diameter copper pipe. In this case, its equivalent thermal conductivity reaches 8.1?104 W/m ?C, which can effectively reduce the temperature of the motorized spindle rotor and make the temperature distribution of the motorized spindle more uniform.
Dynamic Bonus Pools
Authors: Budde Jörg , Hofmann Christian
Published: December 2023

We study the properties of long-term bonus pools (BPs) with rollover provision in a multiperiod moral hazard setting, where the principal uses subjective information to privately assess the agent’s performance and the agent is protected by limited liability (LL). To provide incentives, the principal funds a multiperiod BP with a fixed payment that may be distributed over time to the agent and a third party. We find that the optimal long-term BP contract features performance targets that are contingent on past performance. Specifically, high subjective performance implies an easy target, and low subjective performance implies a difficult target. To implement the long-term BP contract, the principal provides nondichotomous performance reports. The study contributes to the literature that discusses the mechanisms that make subjective performance information useful for incentive contracting.

Multi-peak Light-emitting Diode Curing Units and Polymerization of 3D-printed Crown and Bridge Resin
Authors: Chung SH , Jiang E-S , Lim B-S , Kim S-H , Chang J
Published: December 2023

Purpose

This study aimed to evaluate the substitutive and additive efficacy of multi-peak light-emitting diode (LED) curing units for post-curing of a three-dimensional- (3D-) printed crown and bridge resin.

Methods

A total of 792 disc- and 180 bar-shaped specimens were printed with a crown and bridge resin (NextDent C&B MFH) and post-cured using two LED curing units (VALO Cordless and Bluephase N G4) in fast and standard modes. Conventional post-curing (LC-3D Print Box, Group PC) was compared with LED-only curing (Groups V1, V2, B1, and B2) and LED-combined curing (Groups PV1, PV2, PB1, and PB2) in terms of microhardness, flexural strength, degree of conversion (DC), and CIE L*a*b* color and translucency parameters. Cytotoxicity of the resin eluates was evaluated using the WST-1 assay. Temperature increases on the resin surface were measured with infrared thermography. Data were statistically analyzed using ANOVA and Kruskal-Wallis tests (α=0.05).

Results

The microhardness and flexural strength in Groups V1, V2, B1, and DC in all LED-only groups were lower than in other groups (p<0.05). Larger color disparities existed between Group PC and all LED-only groups than between Group PC and the others (p<0.05). There was no significant difference in cytotoxicity among the groups. The temperature increase was lowest in Groups V1 and PV1 during light curing (p<0.05).

Conclusions

Post-curing by multi-peak LED curing units was not as effective as the conventional post-curing device. Additional post-curing by LED curing units did not improve the material properties.

English abstract
Physical Learning Environments in Swedish School-Age Educare. Conditions for and Planning of Indoor Environments for a Variety of Possibilities for Actions
This study focuses on the physical learning environments in Swedish school-age educare centres (SAEC) and how SAEC-teachers describe their work with the formation of SAEC environments and the possibilities for action these present to pupils. The study is based on walk-and-talk interviews with teachers in SAEC-centers where the different environments were video-recorded, and the teachers were asked to describe their intentions with these environments. The data has been analyzed thematically. The results show that the possibility to control the premises can be important for the SAECs ability to offer a variety of physical learning environments and of possibilities for action (affordance). Recurring types of physical learning environments have been distinguished where the SAEC-teachers plan for a variety of action alternatives. Pupils are described as co-creators of the environments and find their own possibilities for action in planned environments. SAEC-teachers also describe how they regulate pupils’ interaction with the environments in line with various norms and rules in the SAEC.
Att skapa sig själv och andra: populärkulturen som verktyg för samtal i fritidshemmets vardag
Authors: Jansson Magnus , Wallner Lars
Published: December 2023

Arbete i fritidshem innebär en stor variation av material och aktiviteter i att möta elevers behov, intressen och erfarenheter, men även utmana dem att utvecklas i sina intressen. Populärkulturen erbjuder ett underlag för detta, som arena för barn att dela erfarenhet och kunskap. I denna artikel undersöker vi hur populärkulturella uttryck skapas i fritidshemmet. Studien bygger på fältobservationer med fritidshemspersonal (n=7) och barn (n=47), i årskurs 2 och 3. Resultatet visar hur elever använder populärkultur för att visa intressen, individualitet, grupptillhörighet, värderingar och status. Detta kan vara problematiskt, då barn inte alltid själva väljer vilka attribut som skapas utifrån den populärkultur de förknippas med, och dessutom kan viss populärkultur strida mot det sociala och pedagogiska uppdrag som fritidshemmet har. Det är därför viktigt att inte enbart förbjuda barns intressen, utan skapa samtal, och ett fokus för diskussion, för att medvetandegöra både barn och vuxna om populärkulturens influens i barns liv.
Fra redaksjonen: Barn i krig
Authors: Ursin Marit
Published: December 2023

«Enhver krig er en krig mot barn.» Eglantyne Jebbs berømte ord har fått en ny og enda sterkere betydning i disse dager. For 100 år siden, i etterdønningene og etterpåklokskapen av første verdenskrig, begynte Jebb arbeidet med en erklæring om barns særegne rettigheter og det internasjonale samfunnets plikter til å sikre disse. Året etter ble den internasjonale Genève-erklæringen vedtatt i Folkeforbundet, og dannet forgjengeren til FNs barnekonvensjon. I disse dager er vi alle vitner til at barns fundamentale rettigheter – deriblant barns iboende rett til liv, til å overleve og vokse opp (FN-sambandet, 1989/2023, art. 6) – ser ut til å ha mistet all sin kraft og verdi.
Uønsket fravær av variasjon i helsesektoren
Authors: Godager Geir
Published: December 2023

Helse- og omsorgsdepartementet krever i oppdragsdokumenter at regionale helseforetak skal redusere uønsket variasjon i bruken av spesialisthelsetjenester. En utfordring beskrevet av Riksrevisjonen er at det bør vurderes skjønnsmessig for hvert enkelt tilfelle hvorvidt påvist variasjon i tjenestebruk er uønsket eller ønsket. Eksemplene i denne artikkelen viser at det også kan være grunn til å vurdere skjønnsmessig for hvert enkelt tilfelle hvorvidt et fravær av variasjon i tjenestebruk er uønsket eller ønsket. Eksemplene viser i tillegg at omfanget av problematisk underbehandling i spesialisthelsetjenesten kan være størst i det området der omfanget av uforklart variasjon er minst. Det er altså ikke opplagt at oppdragsdokumentenes krav om å redusere uønsket variasjon er formålstjenlig. Et alternativ som med fordel kan vurderes, er å utforme oppdragsdokumenter der tiltak for etterlevelse av prioriteringsforskriften tillegges større vekt enn i dag.

Published: December 2023

The industry is growing rapidly, indirectly forcing business actors to pay attention to the quality of the goods they produce during the production process. Companies must maintain the quality of their products because quality affects how satisfied customers are with a product. PT. XYZ is a company engaged in steel construction and fabrication. The problems that often occur are defects such as Overlap welding defects, Porosity welding defects, and unavoidable Cutting process defects. This study aims to determine the level of damage, identify the factors that cause damage and recommend corrective actions. Statistical quality control methods are used to identify the causes of defects in the production process, with statistical tools including: check sheets, histograms, Pareto charts, Control Chart diagrams, and fishbone diagrams. The results showed that product damage or defects were within reasonable limits but corrective action was needed to reduce defects. It can be seen from the Pareto diagram that the Overlap welding defects are 37.5% more than all product defects. Proposed improvements that need to be implemented by the company are cleaning the material before welding, performing treatment on the welding wire according to the Quality Control department's recommendations, checking the machine's stability before use and carrying out machine maintenance once a week.

The rapid advancement of the internet has led to some shifts in daily activities. Some conventional activity is now slowly shifted to online, including playing online games. Online games have both impacts, positive and negative. The advantage of online games is to help people communicate with other parties anywhere and anytime in the world. On the other hand, the negative impact is an addiction which leads to losing track of time and neglecting their responsibilities. This study aims to analyse online game addiction using a mathematical model. The mathematical model used is the SEAR model with four compartments, susceptible, exposed, addiction and recovery. The population of this study is limited to cases of addiction to online games on gadgets and ignores the factor of having professional players (e-sports). We obtained the basic reproduction number is , which means that online game addiction does not occurs in the population. Sensitivity analysis showed that the rate of susceptible gamer to be exposed gamer and the rate of individuals who addicted to online game are the parameter which prone to change. The numerical simulation also shown that the change in α brings an impact to the overall dynamics.
Des images attaquées : la soupe sur les tableaux et le déclin de la contemplation
Authors: ANDREESCU Radu-Cristian
Published: December 2023

Images under Attack: Soup on Paintings and the Decline of Aesthetic Contemplation.
In 2022, two cans of tomato soup were thrown over Van Gogh’s Sunflowers at the National Gallery in London by two climate activists. The aim of this paper is not to explain the motives behind the protest in terms of environmental activism, but to address the implications of this phenomenon for the status of artistic images in our time. The protest in question is one of the many symptoms of the fact that images associated with a pure state of gaze have become morally dubious due to a certain moralistic turn in contemporary discourses on art. Consequently, what seems to be lost in today’s movements of moralizing aesthetics, whether in art or in environmental activism, is not only the “aura” of an artwork, but also the idea that the contemplation of beauty in and for itself would provide a foundation for humans’ moral vocation. In a gaseous state of art (Y. Michaud) in which the transient effects of things are more important than their essence, the moralistic tendencies combined with the lack of moral foundations can no longer conceive of the ethical effects of images without explicit moral content, thus calling for a new form of heteronomy in art.

A batalha pelo direito internacional durante a era da descolonização foi, em grande parte, uma batalha travada tendo como alvo a natureza, função e objetivos do Estado. Já o ponto final pré-determinado da emancipação política de acordo com a ordem legal de meados do século XX, a tarefa enfrentada pela primeira geração de líderes pós-coloniais, era domesticar, aproveitar e direcionar o Estado para um novo futuro. De forma crucial, e também tragicamente, talvez, suas lutas para este fim foram radicalmente moldadas pelo projeto de desenvolvimento – desta vez, “cria” mais recente da ordem jurídica internacional. O Estado, o desenvolvimento e o direito internacional eram, nesta ordem das coisas, três das principais coordenadas que vieram para organizar a descolonização de povos do Sul. Hoje, várias décadas após o fim do imperialismo formal, ainda estamos lidando com a formação política, econômica, social e administrativa muito particular que resultou desta batalha: o "estado desenvolvimentista".

Optimized planning framework of solar photovoltaic based generation with EV charging station in a rural distribution network considering uncertainties
Authors: Tripathy Sasmita , Nandi Sharmistha , Ghatak Sriparna Roy , Acharjee Parimal , Sinha Pampa
Published: December 2023

To address the adverse impacts due to rapid growth of electric vehicles (EVs), a robust planning framework is developed in this paper for optimal deployment of EV charging stations and solar energy resources in the distribution network. Uncertainty modeling of EV is done using probability density function considering stochastic parameters extracted from real National Household Travel Survey (NHTS)datasheet. Considering solar irradiance as the uncertainty parameter, a practical Photovoltaic (PV) model is developed using beta probability function. To solve the problem of optimal allocation of EV charging stations and PV in the distribution network, proposed Teaching Learning Based Optimization algorithm is used. The problem is formulated to minimize the power loss reduction index and the voltage deviation index while considering system constraints. Here this proposed approach is tested to Indian 28 bus rural distribution network and standard IEEE 69 bus system in MATLAB. Also to assess the efficiency of the proposed technique, it is compared with three different algorithms, i.e., Genetic Algorithm (GA), Particle Swarm Optimization (PSO) and Differential Evolution (DE) in terms of convergence characteristics and computational time. The system indices, i.e., voltage profile, line loss, voltage stability and the penetration level of EV charging station are improved after simultaneously optimally deploying EV charging station and PV units both in rural and standard 69 bus distribution networks. Different case studies were conducted and it was observed that deployment of EV charging station in the network leads to deterioration of voltage profile, voltage stability and line loss. The simulation outcome further reveals that the addition of PV panels concurrently with EV charging stations enhances the system performances and the penetration level of EV charging station in the network.
Crude oil price-exchange rate nexus in Pakistan
Authors: Iqbal Farhat , Raziq Abdul
Published: December 2023

This paper studies the association between price of crude oil and the Pakistani Rupee-US Dollar exchange. Asymmetric power autoregressive conditional heteroscedastic (APARCH) model is used to measure the influence of oil price on the nominal exchange rate using daily data of extreme oil price volatility (2006 – 2013). This model is found to fit the data well and the results reveal a high degree of volatility persistence and leverage effect in returns. This study also establishes a positive association between currency exchange rate and oil price. These findings provide insight into the transmission link between the global oil market and exchange rate.
Risk Governance Structure and Firm Performance: An (Exploratory) Empirical Study in Indian Context
Authors: Shivaani M.V.
Published: December 2023

The study attempts to explore the relationship between riskgovernance structureand firm performance. In perhaps the first of its kind attempt, a normative framework for risk governance structures is being put forward. Based on the framework, an index indicating strength/quality of risk governance structures is proposed. Then, the impact of risk governance structure on firm performance is gauged. To this end, the study makes use of constituents of S&P CNX500 index and covers a ten year period from April 1, 2005 to March 31, 2015.To control for potential endogeneity among variables of interest, the study makes use of a robust and reliable methodology,‘difference-GMM’. In addition, to ensure completeness of results, the study employs control variables such as recession dummy, firm’s age, size, and growth rate and leverage ratio. The results suggest that robust risk governance structures do not necessarily lead to better firm performance. In fact, risk governance index is negatively related to both ROA and ROE. The relationship is not statistically significant but has wide economic implications. A prominent implication being, mere constitution of risk management committee and appointment of CRO will not improve firm performance; regulators and companies need to ensure that governance structures are not too rigid, excessively risk averse and ineffective and inefficient in decision making. Given the simplicity and reliability of the proposed risk governance index, and the recommendations put forth in the paper, the study is expected to be of immense utility in an important yet neglected area of risk governance.

The predominant CAT system was the Invisalign appliance (70.3%; N = 45) with 49.2% (N = 32) stating that they used more than one CAT system. The respondents reported the areas which were always or mostly in need of amendment prior to acceptance of the CAT treatment plan were attachments (75.6%; N = 50) and final tooth positions (62.1%; N = 41). A median of 0% (IQR: 0, 1) of initial digital treatment plans were approved without changes according to the respondents with a median of 90% (IQR: 80, 99) of CAT patients requiring an additional aligner phase. Almost 80% (78.1%; N = 50) indicated that they were not comfortable in treating cases with increased overbite and 66.7% (N = 44) rarely or never carried out premolar extractions when using CAT. A remote monitoring system was mostly or always used by 32.4% (N = 21) of respondents in conjunction with CAT. Concern regarding patient compliance with CAT protocols was expressed by 43.5% (N = 22). That fixed appliances provided better treatment outcomes was a moderate or major influence on the decision of all respondents (N = 8) who did not provide CAT.

Conclusion

Although CAT provision by orthodontists is commonplace among orthodontists in New Zealand, there is wide variation in its usage and procedures.

Contrast-free MR-perfusion of "labeled arterial blood spins" ("ASL-perfusion") is an MR-technology for qualitative and quantitative assessment of tissue perfusion properties based on of arterial blood proton spins labeling by radiofrequency pulses and their subsequent measurement when passing through the area of interest. The most of ASL-perfusion application clinical data referred to central nervous system diseases diagnostics, but some works showing the effectiveness of this technique in assessment of skeletal muscle perfusion and diagnostics of soft tissue tumors appeared recently.

Two presented clinical cases (soft tissue tumor and post-traumatic benign changes) demonstrate the possibility of this technique usage to assess vascularization of pathological changes in hip soft tissues.

Mastitis is an inflammatory condition that occurs in breastfeeding mothers in the first month postpartum. The incidence of mastitis is around 9-20% which is caused by a lack of frequency of breastfeeding, errors in breastfeeding and pressure on the breast tissue. In this study, we examined the relationship between mastitis and postpartum depression. reviewed from Google Scholar database and other related websites. With the keywords "mastitis, depression, postpartum". A total of 3 out of 3,140 were then selected according to the theme and similarities were searched for from each journal found. Publication range from 2019 to October 2023. obtained from a population of 1,555 people who experienced mastitis, 147 with significant results of 68% that those who experienced mastitis would harm themselves and desire suicide and mothers over 35 years of age would be more at risk of developing depression Mothers who breastfed were 74.67 ± 4.35; the average EPDS score was 5.73 ± 4.34. And mothers suffering from lactational mastitis had higher EPDS scores at 34-38 weeks of gestation and experienced an increase in EPDS scores. at 6 weeks postpartum The occurrence of physical difficulties or health problems during breastfeeding has been associated with a greater risk of developing mental symptoms of health problems in the postpartum period. In particular, several prospective studies have shown that there is an association between the presence of physical health problems and the first 3 months (or more) after giving birth and the emergence of depressive symptoms in women at the age of 6 to 12 months postpartum

INTRODUCTION: Neonatal ultrasound began in the 1970s to evaluate cerebral hemorrhages. With the advent of different transducers and improvement of the technological devices (Doppler function), its use has greatly expanded, being possible the evaluation many organs. OBJECTIVES: The study aims to show new applicability of ultrasonography, as an auxiliary method in the diagnosis of spinal alterations, pulmonary diseases, and cranial sutures in the neonatal period. METHODS: Descriptive study of ultrasound examinations performed with the Logiq P7 device of General EletricT, with multifrequency and microconvex transducers with frequency of 3 to 11 MHz and linear with frequency of 2 to 11 MHz. Ultrasound evaluations were performed immediately after diagnostic suspicion, by a specialist physician with more than 15 years of experience in pediatric ultrasound, provided that the clinical condition of the newborn allowed the examination and, if there was a need, a new ultrasound would be performed for diagnostic confirmation. RESULTS: Presentation of ultrasound images performed routinely in a neonatal tertiary-level unit, including evaluations of spine, lungs and skull bones presented as well: 1. Ultrasonography of normal neonatal spine (medullary cone and cauda equina). 2. Normal neonatal chest ultrasound, with the presence of A-lines and rare B-lines, and graphic representation of normal diaphragmatic mobility. 3. Ultrasound of the pervious and closed sagittal cranial suture. CONCLUSIONS: Ultrasonography has several applicability, and its use in the neonatal population favors satisfactory the diagnosis and follow-up of various pathologies, in a noninvasive and innocuous manner, reserving the other diagnostic methods for cases in which diagnostic complementation is necessary.

Different from traditional universities, which have been formed for a long time to focus on solving academic problems and developing theories, since the beginning of the 20th century, ​​urban universities has evolved from universities, located in the urban environment, into universities functioned to connect and develop urban areas. These universities were conceived to leverage local resources and uniqueness, provide access to higher education and work with partners to help cities be more successful in all aspects of their urban lives. Nowadays, with more than 85% of the US population living in urban areas, the urban focus would be ubiquitous in higher education. In Vietnam, the proportion of the population in urban areas is dramatically increasing, urban development and expansion is a dynamic process and requires a high concentration of research. Issues of urban infrastructure construction, traffic, changing living culture, building urban civilized institutions, livelihoods for people in the process of urban transformation, legal relations, markets, civic groups, etc., requires the formation of highly concentrated academic and research centers mentioned above. Within the framework of the Strengthening Provincial Capacity (SPC) project funded by the United States agency for international development - USAID, the School of Government of the University of Economics Ho Chi Minh City (a local institute) was selected to participate in the project's training programs. Before the end of the project lasting for more than two years, the authors of the School of Government had a working trip to Portland State University (PSU), a typical successful urban university. The presentation of an in-depth study of PSU itself - a locally cohesive research university - that solves major problems of Portland in particular, Oregon and the United States in general is the author's desire to introduce the urban university model to universities in Vietnam.

The article considers the possibility of measuring the quality of life of the rural population using the author's formulas on the example of the Kulundinsky district of the Altai Territory. The data obtained during the sociological research were integrated into the author's formulas and used to calculate the quality of life index and the real quality of life. The methodology of this work was based on a combination of structural functionalism and a systematic approach. The article presents the results of the author's sociological research, which was conducted in the period from 2022 to 2023. The empirical data obtained became the basis for the derivation and application of the author's formulas for the quality of life. In addition, the data obtained make it possible to reflect the current state of affairs in modern rural areas, as well as to characterize the quality of life of the rural population both in terms of objective and subjective components of quality of life.  The process of researching the quality of life was carried out both by quantitative methods – a mass survey in the form of a questionnaire n=954, and by qualitative methods – a focus group n=108, an expert survey in the form of an in-depth interview n = 30, and an analysis of documents was also applied. The novelty of this work lies in measuring the quality of life of the rural population by applying two formulas: the quality of life index and the real quality of life. The results of the calculations completely coincide with the real state of affairs in the modern village, which gives the author the right to consider them workable and actually operating. The special value of this work lies in the possibility of extrapolating the methodology of this sociological study, in particular, the formulas of quality of life to other districts of the Altai Territory, as well as to other regions. This will allow the authorities to pinpoint and quickly identify problems in certain areas and resolve them promptly, which will lead to a further increase in objective and subjective indicators of the quality of life in modern rural areas.
