Effect of parameters-dependent viscosity and thermal conductivity on the thermo-hydraulic performance of Al2O3-based nanofluids in a rectangular micro-channel
Authors: Huang Hongyan , Li Chunquan , Shang Yuling , Huang Siyuan
Published: May 2024

The multi-parameter dependence of nanofluid viscosity and thermal conductivity on the flow and heat transmission properties of Al2O3-water nanofluid in micro-channels is investigated in this paper using a numerical simulation approach, exploring the effects of various parameters on flow and heat dissipation characteristics, such as flow velocity, pressure drop, temperature, and heat transfer coefficient, under different Reynolds numbers, etc. These parameters include the nanoparticle sphericity (0.5~1.0), volume fraction (0.6~6.0%), and temperature (290~370K) of the nanofluids, as well as the boundary parameter Reynolds number (200~1000). The results show that the multi-parameter dependence of nanofluid viscosity and thermal conductivity setting has a significant impact on the flow and heat dissipation characteristics of nanofluids, comparing analysis with the nanofluid viscosity and thermal conductivity only related to the volume fraction under the same condition. Under the combined action of sphericity, volume fraction, and temperature, increasing the sphericity increases the pressure drop and decreases the heat transfer coefficient. For example, at a Reynolds number of 1000, the maximum rates of change for pressure drop and heat transfer coefficient are 0.85 and 4.26, respectively. The nanofluid thermo-hydraulic performance is sensitive to temperature, volume fraction and sphericity in turn. Setting up viscosity and thermal conductivity equations with multiple parameter dependencies can provide more accurate results for the research of nanofluids, further deepening the application research of nanofluids.

Authors: Steding-Jessen Marianne , Engberg Henriette , Jakobsen Erik , Rasmussen Torben Riis , Møller Henrik
Published: May 2024

Background and purpose: There has been marked progress against lung cancer in Denmark. To gain further insight into the different aspects of the improvement, we examined the stage-specific incidence rates, stage-specific survival and mortality rates.
Materials and methods: We used information from the Danish Lung Cancer Registry on date of diagnosis and clinical stage to calculate age-standardised incidence rates and patient survival by sex, period and stage. Information about age-standardised lung cancer-specific mortality rates by sex and period was extracted from The Danish Health Data Authority.
Results: Firstly, the decrease in incidence rates was due to a reduction in the rates of advanced stages. Secondly, there was a gradual increase in survival across all stages, and thirdly, the mortality rates gradually decreased over time.
Interpretation: The improvements in survival and mortality from lung cancer were due to decreasing incidence rates of advanced cancer and improvement in survival at all stages of the disease.

Authors: Stervik Christina , Lith Agneta , Ekestubbe Annika
Published: May 2024

Objectives: To estimate radiation risk to children and adolescents during orthodontic treatment by retrieving number and type of radiographs from the patient records. Material and methods: Radiographs, along with justifications for radiation exposure, were obtained retrospectively from the patient records of 1,790 children and adolescents referred to two Swedish orthodontic clinics. Data were grouped according to treatment stage: treatment planning, treatment, and follow-up. Estimated risk was calculated using the concept of effective dose. Results: Each patient had received around seven radiographs for orthodontic purposes. The most common exposures during treatment planning were one panoramic, one lateral, and three intraoral periapical radiographs. A small number of patients received a tomographic examination (8.2%). Few justifications for treatment planning and follow-up, but more in the actual treatment stage, had been recorded. The most common examinations were to assess root resorption and the positions of unerupted teeth, or simply carry out an unspecified control. The estimated risk of developing fatal cancer was considered low. The radiation risk from orthodontic treatment was equivalent to about 5–10 days of natural background radiation. Conclusions: Children and adolescents sometimes undergo multiple radiographic examinations, but despite the low radiation burden, accumulated radiation exposure should be considered and justified in young patients.

Humans in everyday life need space as a container for their activities. Ideally, space is planned and designed based on prior activity analysis. However, in reality, humans often get existing housing as a place to carry out activities. This research is a qualitative research that aims to describe and interpret spatial adaptations in vernacular dwellings. The research case is the houses in the Kudus Old City with the boundaries of houses that have the original form of the traditional Kudus house. Data collection was carried out by observation and interviews, which were carried out simultaneously with the analysis process. The results of this study found that spatial adaptations that occur in vernacular dwellings in the Old City of Kudus follow levels or spatial hierarchies. In addition, various adaptation strategies were also found in space in the form of spatial changes, changes in spatial functions, and changes in spatial size. These changes were made as a spatial adaptation effort with the aim of not only meeting the needs but also to increase the comfort of dwelling users. Kata kunci: spatial adaptations, dwelling, vernacular

ATP2C1 knockdown induces abnormal expressions of cytoskeletal and tight junction proteins mimicking Hailey–Hailey disease
Authors: Zhou Mingzhu , Kang Shiran , Xia Yumin , Zhang Dingwei , Chen Wenwen
Published: May 2024

Background

Hailey–Hailey disease (HHD) is a rare, autosomal dominant, hereditary skin disorder characterised by epidermal acantholysis. The HHD-associated gene ATPase calcium-transporting type 2C member 1 (ATP2C1) encodes the protein secretory pathway Ca2+ ATPase1 (SPCA1), playing a critical role in HHD pathogenesis.

Aims

We aimed to investigate the effect of ATP2C1 knockdown on keratinocytes that mimicked acantholysis in HHD.

Methods

Immunohistochemistry (IHC) was employed to evaluate the levels of cytoskeletal and tight junction proteins such as SPCA1, P-cofilin, F-actin, claudins, occludin, and zonula occludens 1 in the skin biopsies of patients with HHD. Subsequently, the expression of these proteins in cultured ATP2C1 knockdown keratinocytes was analysed using Western blotting and immunofluorescence. Furthermore, we assessed the proliferation, apoptosis, and intracellular Ca2+ concentrations in the ATP2C1-knocked keratinocytes.

Results

The results showed decreased levels of these proteins (SPCA1, P-cofilin, F-actin, claudins, occluding, and zonula occludens 1) in HHD skin lesions. Moreover, their levels decreased in human keratinocytes transfected with ATP2C1 short hairpin RNA, accompanied by morphological acantholysis. Furthermore, the proliferation and apoptosis of the keratinocytes, as well as intracellular calcium concentrations in these cells, were not affected.

Limitations

The limitations of this study are the absence of animal experiments and the failure to explore the relationship between skeletal and tight junction proteins.

Conclusion

The present study indicated that ATP2C1 inhibition led to abnormal levels of the cytoskeletal and tight junction proteins in the keratinocytes. Therefore, keratinocytes can mimic HHD-like acantholysis and serve as an in vitro model, helping develop treatment strategies against HHD.

Unraveling the structure and composition of Li4Mn2O4.5 (Li2O•Li0.667Mn1.333O2) electrodes for lithium batteries
Authors: Tornheim Adam , Vu Anh , Roy Indrani , Johnson Christopher , Croy Jason , Thackeray Michael
Published: May 2024

This communication addresses the debate about the composition and structure of a lithium-rich manganese oxide electrode with a fully disordered Li-Mn-O rock salt component that was first reported as Li4Mn2O5 (Li2O•2LiMnO2), by Freire et al. in 2015. When prepared at 800 C, it has been determined that the formula of this compound can be designated more accurately as Li4Mn2O4.5, alternatively Li2O•Li0.667Mn1.333O2, or close thereto. The cubic, disordered Li0.667Mn1.333O2 (or Li0.333Mn0.667O) rock salt component, in which the manganese ions adopt an average oxidation state of 2.5+, transforms to a clearly-defined spinel configuration during electrochemical cycling. The electrochemical activation process during the initial charge reaction appears to include the oxidation of the manganese ions by oxygen released by the Li2O component between 4.5 and 4.6 V. In complete contrast, nickel-substituted electrodes, such as Li2O•2LiMn0.5Ni0.5O2 and Li2O•2LiMn0.475Ni0.475Co0.050O2, in which the manganese ions adopt a tetravalent state, have disordered rock salt components that are electrochemically inactive.
Digital-inclusive Transformation and Teacher Preparedness for Foreign Language Education – A Bilateral German-Norwegian Perspective
Authors: Chilla Solveig , Doetjes Gerard , Vogt Karin , Tsagari Dina , Abed Ibrahim Lina
Published: May 2024

Digitalisation and inclusion can be understood as transversal topics in pre- and in-service teachers’ professional development. Both topics have attracted considerable research activity. However, questions of digital-inclusive transformation have only rarely been discussed within the field of foreign language teaching. Researchers in the field state a pressing need to increase digital-inclusive transformation uptake in foreign language teacher education programmes to develop a transformation ‘mindset’ in (educational) stakeholders and (future) teachers. Transformation processes in education, however, interact with preparedness for digitalisation and inclusion among pre- and in-service teachers, since the attitude and the willingness of teachers to adapt to digital reality play a decisive role in improving the quality of (digitally enhanced) teaching and learning. Currently, little is known about the interrelationship between the preparedness to use digital technology for foreign language teaching and learning and the preparedness to include foreign language learners with diverse learning needs (DLN) in the digital-inclusive classroom. To this end, this bilateral cross-country study investigates factors that constitute an attitudinal component of foreign language teachers’ perceived preparedness for using digital technology with learners with diverse learning needs in Germany and Norway. The Teacher of English Preparedness to Diverse Learning Needs in the digital inclusive classroom questionnaire was administered to 221 participants. The results show a fresh perspective on preparedness for digitally enhanced inclusive teaching linked to educational system requirements for foreign language teaching. Importantly, confidence when using digital technology in the inclusive classroom is decisive. For teacher education, it is vital that the attitudinal component of teacher preparedness receives more attention throughout teacher training. It should be related to previous experience of teachers with DT in digital-inclusive environments and be part of a heuristic conceptualisation of teacher preparedness for digitalinclusive contexts.

Antioxidant activities of lemon and mandarin peel extracts as natural
preservatives in ghee (butter oil) stored at different storage temperatures
Authors: Darwish A.M.
Published: May 2024

Using natural preservatives in ghee and fat-rich products has great economic importance
as it can minimize adverse effects on human health and improve the marketing prospects
of products. The present study aimed to use lemon (Citrus lemon L.) and mandarin (Citrus
reticulata L.) peel extracts as natural preservatives instead of synthetic antioxidants of
butylated hydroxyanisole (BHA) to retard the oxidation of ghee during accelerated storage
at various temperatures. Antioxidant activities of lemon peel extracts (LPE), mandarin
peel extracts (MPE) and BHA in ghee samples stored at different storage temperatures
(T1: 5±2°C, T2: 25±2°C, T3: 60±2°C) were evaluated during the storage period (0, 20 and
40 days). The peroxide value (PV), free fatty acids (FFA), and antioxidant activity of the
ghee samples were analyzed and compared with control sample (without additives). The
PV and FFA content were significantly higher in the control sample than in the ghee
samples treated with BHA, LPE, and MPE at all storage temperatures and during the
storage period. All treatments led to a reduction in the PV and FFA content, but LPE had
the most significant effect, followed by BHA and MPE, respectively. Antioxidant activity
was evaluated by the 3-ethyl benzthiazoline-6-sulphonic acid (ABTS) assay; LPE had the
highest antioxidant activity, followed by MPE. Compared to the control sample: BHA,
LPE and MPE led to a higher reduction in the PV and FFA content of ghee samples at all
storage temperatures and periods owing to their antioxidant activities. Results of
incorporated samples showed that using LPE (0.1%) prevented the development of PV
and FFA content of ghee samples less than using BHA (0.2%). The present study suggests
that LPE (0.1%) could be used as a good natural antioxidant preservative to reduce
oxidative deterioration of ghee and fat-rich products.

properties are presented to assess product preference from panellists. The result showed
that the β-carotene and vitamin C in 20% and 40% treatments were 12.641 to 27.922 μg/
kg and 5.06 to 7.392 mg/kg, respectively. The moisture content in control, 20%, and 40%
treatments were all below 5%. NaCl content, as the major compound in the product, was
affected by adding M. oleifera leaf extract into the product. Applying 40% M. oleifera leaf
extract to the salt significantly decreased the NaCl content of the product compared with
20% treatment and control. All sensory properties attributes have decreased as an increase
of M. oleifera leaf extract concentration. Compared with the 40% treatment, the 20%
treatment showed a higher value of sensory properties. A preference for salt fortification
was also shown at the 20% treatment in the neutral midpoint. Thus, an additional 20% of
M. oleifera leaf extract provided higher nutritional content than the control and was more
acceptable to consumers than the 40% treatment.

Remaja menuju dewasa merupakan tahap perkembangan, dimana terjadi masa perubahan atau peralihan dari masa remaja menuju batas kedewasaan yang meliputi perubahan biologik, psikologik, dan sosial. Perubahan tersebut menyebabkan perubahan perilaku menuju kedewasaan. Namun seringkali perubahan perilaku ini  tidak mencerminkan suatu kedewasaan. Salah satu penyimpangan yang dianggap menyimpang karena melanggar norma-norma masyarakat dan agama adalah perilaku seksual. Potensi terjadinya perilaku seksual di luar nikah dikalangan remaja dan mahasiswa lebih besar, karena belum tahu dampak perilaku seks di luar nikah dan seks tidak aman. Perilaku tersebut dapat berakibat fatal bagi remaja karena berisiko tinggi terhadap timbulnya kehamilan di luar nikah, tertular penyakit menular seksual dan HIV/AIDS, aborsi yang tidak aman, hingga kematian.Tujuan penelitian ini dilakukan untuk menganalisis peran orangtua, teman sebaya, dan ketaatan beragama terhadap perilaku seks pranikah pada remaja di Desa Prambatan Lor Kabupaten Kudus. Metode yang digunakan adalah desain deksriptif korelatif, dengan metode pendekatan cross sectional. Instrumen yang digunakan kuesioner. Tehnik analisa data dengan data univariat dan bivariat. Hasil penelitian menunjukkan bahwa ada hubungan peran orang tua dengan perilaku seks pranikah pada remaja (p value =  0,006), ada hubungan peran teman sebaya dengan perilaku seks pranikah pada remaja (p value = 0,000), dan ada hubungan ketaatan beragama dengan perilaku seks pranikah pada remaja (p value =  0,001).  Perlu adanya perhatian lebih dari peran orangtua dalam mendampingi dan membimbing putra putrinya dalam menjalani tahapan perkembanganya. Lemahnya peran controlling oleh orang tua kepada anaknya mengakibatkan remaja bebas berperilaku yang bisa berdampak buruk pada kesehatan reproduksinya.
