A few remarks on the Triassic paleogeography and geodynamic link between the Dinarides an the Serbo-Macedonian unit
Authors: Spahic Darko , Gaudenyi Tivadar
Published: July 2020

A recently recycled tectonic hypothesis in which the Serbo-Macedonian Unit rifted off during Ladinian from the Dinarides is tested. The Triassic rifting, according to this concept, led to the opening and the formation of a northwestern branch of Neotethys (=Vardar Ocean). Similar concept explains the developments within the Inner Hellenide allochoton (Serbo-Macedonian Unit and Pelagonides). The testing of early Alpine configuration in Serbia shows, however, that the two crystalline basement units have significant paleogeographic variances. The study moreover includes the differences in Paleozoic metamorphic grades between two inliers, their exhumation times, etc. The investigated pre-Triassic paleogeographic and geodynamic variances unambiguously contradict any connection before and during Triassic (Ladinian). In this regard, by using the available field data, and the juxtaposed Late Paleozoic Variscan tectonometamorphic differences, the paper underscores the large differences in the (pre)Triassic plate configurations and paleogeography. The synthesis displays the two separate positions of these microplates situated along with the length of this segment of the Triassic Eurasian continental margin.
Dyson spheres
Authors: Wright Jason
Published: July 2020

I review the origins and development of the idea of Dyson spheres, their
purpose, their engineering, and their detectability. I explicate the ways in
which the popular imagining of them as monolithic objects would make them
dynamically unstable under gravity and radiation pressure, and mechanically
unstable to buckling. I develop a model for the radiative coupling between a
star and large amounts of material orbiting it, and connect the
observational features of a star plus Dyson sphere system to the gross
radiative properties of the sphere itself. I discuss the still-unexplored
problem of the effects of radiative feedback on the central star's structure
and luminosity. Finally, I discuss the optimal sizes of Dyson spheres under
various assumptions about their purpose as sources of low-entropy emission,
dissipative work, or computation.

We recently demonstrated that removal of one kidney (uninephrectomy [UniNx]) in mice reduced high-fat diet (HFD)-induced adipose tissue inflammation, thereby improving adipose tissue and hepatic insulin sensitivity. Of note, circulating cystatin C (CysC) levels were increased in UniNx compared with sham-operated mice. Importantly, CysC may have anti-inflammatory properties, and circulating CysC levels were reported to positively correlate with obesity in humans and as shown here in HFD-fed mice. However, the causal relationship of such observation remains unclear. HFD feeding of CysC-deficient (CysC knockout [KO]) mice worsened obesity-associated adipose tissue inflammation and dysfunction, as assessed by proinflammatory macrophage accumulation. In addition, mRNA expression of proinflammatory mediators was increased, whereas markers of adipocyte differentiation were decreased. Similar to findings in adipose tissue, expression of proinflammatory cytokines was increased in liver and skeletal muscle of CysC KO mice. In line, HFD-induced hepatic insulin resistance and impairment of glucose tolerance were further aggravated in KO mice. Consistently, chow-fed CysC KO mice were more susceptible to lipopolysaccharide-induced adipose tissue inflammation. In people with obesity, circulating CysC levels correlated negatively with adipose tissue Hif1α as well as IL6 mRNA expression. Moreover, healthy (i.e., insulin-sensitive) subjects with obesity had significantly higher mRNA expression of CysC in white adipose tissue. In conclusion, CysC is upregulated under obesity conditions and thereby counteracts inflammation of peripheral insulin-sensitive tissues and, thus, obesity-associated deterioration of glucose metabolism.
High-Sensitivity Cardiac Troponin-T and N-Terminal Prohormone of B-Type Natriuretic Peptide in Relation to Cardiovascular Outcomes in Type 1 Diabetes
Authors: Costacou Tina , Saenger Amy K. , Orchard Trevor J.
Published: July 2020

Objective: High-sensitivity cardiac
Troponin-T (hs-cTnT) and N-terminal pro B-Type natriuretic peptide (NT-proBNP),
biomarkers of cardiovascular disease (CVD) and heart failure, respectively,
have not been widely studied in type 1 diabetes (T1D). We evaluated whether their assessment in T1D enhances the
prediction of CVD and major atherosclerotic cardiovascular events (MACE).

Research Design and Methods: hs-cTnT and NT-proBNP were analyzed on the Roche Cobas
E601 utilizing the first available stored specimen (n=581; mean age 29
and duration 21 years). CVD was defined
as CVD death, myocardial
infarction, coronary revascularization, angina, ischemia, or stroke and MACE as CVD death, myocardial
infarction, or stroke.

Results: Median hs-cTnT (5.0 ng/L, IQR: <3.0, 10.0) was higher among men
(p<0.0001), whereas median NT-proBNP (22.0 ng/L; 7.0, 61.0) did not differ by sex. In Cox models, log hs-cTnT (HR=1.38, p=0.0006) and log NT-proBNP (HR=1.24, p=0.0001) independently
predicted CVD during 21 years of follow-up.
However, their addition to models either singly or together did not
significantly improve CVD prediction.
Furthermore, a marginally significant sex interaction was
observed (p=0.06), indicating that hs-cTnT’s prediction was limited to men.
hs-cTnT and NT-proBNP also predicted MACE, although only NT-proBNP remained significant
(HR=1.27, p=0.0009) when the biomarkers were included in a model simultaneously. Nonetheless, their addition to multivariable models
did not enhance MACE prediction.

Conclusions: Sex differences were observed in the
concentration and predictive ability of hs-cTnT and NT-proBNP in T1D. Overall, their addition to traditional risk factor models increased
the area under the curve for neither CVD nor MACE.
A New Approach to Pilot Contamination in Massive MIMO Systems for 5G Communication Networks with Butterfly Optimization Algorithm
Authors: ALTİRAİKİ Salah , TEZEL Necmi Serkan
Published: July 2020

Communication technologies, in particular fifth-generation (5G) mobile phones, are currently developing around the world. Massive multi-input-multi-output (MIMO) systems are usually used in this type of communication network so that a large number of users are able to connect to the network and use its services. Massive MIMO systems are a good solution for 5G communication networks leveraging antennas to improve communication performance. To increase output communication power in 5G networks, the problem was optimized with the butterfly optimization algorithm (BOA). According to the simulation results, the proposed method outperformed other similar communication methods, such as the Random, SPRS, WGC PD and SPRS+WGC PD algorithms in terms of the signal-to-interference-plus-noise ratio (SINR) and rate of connection of users to the network.

Published: July 2020

One of the natural ingredients that to be used to inhibit bacterial growth is the Zingiber officinale. In Indonesia, there are 3 types of ginger which are distinguished by morphology, namely ‘emprit ginger (Zingiber officinale var. Amarum), ‘ gajah’ ginger (Zingiber officinale var. Officinarum), and red ginger (Zingiber officinale var. Rubrum). This research was conducted to determine the activity of extracts and fractions of three ginger varieties in inhibiting the growth of Staphylococcus aureus using the disc diffusion method. The test group consisted of ethanol extract, n-hexane fraction, and ethyl acetate fraction from 3 ginger varieties, concentrations of 5, 10, 20% w / v, gentamicin 10 μg (positive control) and 10% DMSO (negative control). The test results showed that ethanol extracts and fractions from the rhizomes of three varieties of ginger have the ability to inhibit S. aureus at concentrations of 5, 10, and 20% w / v, increasing the concentration will increase the diameter of the inhibition zone. At a concentration of 20% of all samples, the one with the greatest resistance was the n-hexane fraction (diameter of inhibitory zone of emprit ginger 9.80 mm, elephant ginger 9.78 mm, and red ginger 9.90 mm). The difference in ginger variety only affects the antibacterial activity of the ethanol extract, but not the n-hexane and ethyl acetate fractions.

Assessing Walkability in Sulaimani City Center
Authors: Radha Roza Abdullatif , Mohammed-Amin Rozhen Kamal , Ali Alan Faraydoon
Published: July 2020

Walkability within urban design and planning context refers to urban environments that are friendly and supportive for the pedestrian. Walkable environments offer many economic, social, health, and environmental benefits and contribute to UN Sustainable Development Goals (SDGs). In public places, including city centers, walkability is a major asset for making them vibrant by attracting and maintaining pedestrians, including tourists. It is no coincidence that the top tourist destinations and livable cities as well as popular city centers and streets all share walkability character. Walkability quality in city center streets and any urban environment require planning. Good planning needs to be informed by measuring and assessing the state of walkability in existing streets and environments. While the literature presents systematic walkability assessment studies from different city centers of developed and developing countries, such studies are rare in the context of many other developing regions and countries like the Kurdistan Region and the rest of Iraq. Since walkability character can be contextual and affected by different socio-economic and environmental factors and dynamics, systematic and comprehensive assessment of under-researched environments and city centers are essential. To address this gap in the literature, this study systematically assesses the state of walkability in the city center of Sulaimani, the cultural capital of the Kurdistan Region of Iraq, and a UNESCO creative city in literature. This paper report results from assessing and comparing the physical characters of the six major interconnecting streets (Mawlawy, Kawa, Sabunkaran, Peramerd, Goran, and Bekas streets) in the center of Sulaimani city. The assessment considers the five main walkability factors of function, safety, destination, aesthetic, and comfort identified from the literature.

Tujuan penelitian ini untuk mengetahui peranan guru dalam mengembangkan kognitif anak usia dini dan sejauh mana guru dapat berperan dalam mengembangkan kognitif yang dimiliki anak usia dini. Dan hasil penelitian terhadap perkembangan kognitif belum sepenuhnya baik,  dikarenakan guru belum melaksanakan peranannya dengan baik dan ketidak maksimalnya peranan guru disebabkan karena pertama, terlalu banyak pekerjaan yang wajib diselesaikan, seperti membuat PR, dan menyiapkan pembelajaran untuk besok, dan mengoreksi pekerjaan anak-anak, sehingga guru tidak fokus lagi dengan pembelajaran dan perkembangan anak. Kedua  guru kurang dapat memanfaatkan waktu dengan baik. Ketiga guru masih perlu belajar tentang memaksimalkan potensi-potensi peserta didik. Dari satu potensi yang dihargai oleh guru sesungguhnya anak dengan dirinya sendiri akan berusaha memunculkan potensi-potensi yang lain. Karena anak bahagia dan senang dilingkungan sekolahnya. Keempat Guru sudah melaksanakan peranannya tetapi kurang maksimal dan kurang tepat dengan sasarannya, yaitu anak usia dini, pembelajaran yang disajikan guru lebih tepat untuk anak SD yang benar-benar sudah dituntut untuk menekuni pembelajaran dengan serius

Time Banking for Elderly in Hong Kong: Current practice and challenges
Authors: Ng Tommy K. C. , Yim Noel T. S. , Fong Ben Y. F.
Published: July 2020

To reduce the burden of the ageing population, time banking can be one of the possible approaches in the community to maximise social capital. Time banking aims to exchange one’s time to serve others and the time of service can be saved as credit so as to swap for services when necessary. It can create a virtuous cycle for providing and receiving services. Several positive outcomes to service providers and recipients of time banking are identified in this review paper. Nevertheless, there is a lack of practical adoption of time banking in Hong Kong. To analyse the challenges of the adoption of time banking in Hong Kong, the current practices of time banking in Hong Kong will be evaluated. To promote time banking in Hong Kong, governmental, technical and educational support are recommended.
Quality Management of Inpatient Medication Administration in Hong Kong Public Hospitals
Authors: Kwong Kiu Yan , Fong Ben Y.F
Published: July 2020

Medicine maladministration can result in various side effects to patients, including serious complications, extended medical care, incapacity and death. In Hong Kong public hospitals, the pattern of medication error consists of prescribing error usually made by physicians, dispensing error resulted from pharmacists and dispensers, drug administration error caused by nurses and patient-care workers and technology-related error associated with technology used in the drug administration process. Medication Administration Record (MAR) and ward stock are the usual inpatient medication system within Hospital Authority public hospitals before the development of the electronic system, while the Inpatient Medication Order Entry (IPMOE) functions to provide real-time accessibility in patients’ medication profiles by different professions and health units. However, several factors are related with medication errors. For instance, the ambiguous handwriting orders in the MAR prescribed by physicians affect the transcription by pharmacists and the administration procedures in ward by nurses. Administering medicines in ward stock before pharmacists vetting increase the chance of making errors. Poor interface issues between users and system, and the computer over-reliance are also contributed in resultant technology-related errors. In order to reduce the occurrence of medication incidents, implementation of Automated Pharmacy Distribution Systems  helps moving towards a closed loop medication management system. Modifying technologies in barcode assisted medication administration and enhancing the IPMOE with a pop-up message could help intercepting drug administration errors to patients.. The elimination of the potential risks arising from the prescribing, dispensing and drug administration processes brings the achievement of medication safety in Hong Kong public hospitals.

The results of this study in the form of the maximum acquisition of light intensity received by the solar panel on the slope angle. Solar radiation intensity carried out a great effect on the power (Pout) of Photovoltaic cell output, wherein the morning solar radiation intensity is greater with the result that it produces greater power. Sunlight intensity in the afternoon and evening tends to decrease so that the power that is halted is smaller. The magnitude of slope angle carried great effect on the output power (Pout) of Photovoltaic cells, where the greatest power at an angle of 0ᵒ obtained namely maximum Pout 17.01 W and maximum Voltage Vm is 19.5 V. While the minimum power Pout is 12 W and minimum Voltage Vm 14 V which obtained at an angle of 60ᵒ. Greatest efficiency (η) of Photovoltaic cells at an angle of 0ᵒ obtained. This is caused by the Voltage and current output of Photovoltaic cells Vm and Im which tend to decrease when the value of the Photovoltaic cell angle is large. Therefore the efficiency of the Photovoltaic cell output will decrease along with the decrease in the Photovoltaic cell output power.Keywords: Photovoltaic, slope angle, power, efficiency.

Self-concept is the core of individual personality, which plays a role in determining and directing individual behavior. Self-concept cannot be separated from virtuous values that arise from self-identity. This article discusses the philosophy of life and the cultural values of the Banjar people "baiman, bauntung, batuah" which are used to conceptualize themselves. The values obtained from the strong influence of Islamic teachings on the Banjar people. The dominance of Islam in the Banjar community is undoubtedly, in the process of 'becoming a Banjar', many Dayak ethnic groups are 'becoming Banjars when they convert to Islam. In addition to this article discussing one of the unique cultural forms of Banjar people, the culture of the river, in the form of river transportation, pasar terapung, and rumah lanting, has begun to be neglected.

Aims

Current guidelines recommend remote follow-up for all patients with cardiac implantable electronic devices. However, the introduction of a remote follow-up service requires specifically dedicated organization. We evaluated the impact of adopting remote follow-up on the organization of a clinic and we measured healthcare resource utilization.

Methods

In 2016, we started the implementation of the remote follow-up service. Each patient was assigned to an experienced nurse and a doctor in charge with preestablished tasks and responsibilities. During 2016 and 2017, all patients on active follow-up at our center were included in the service; since 2018, the service has been fully operational for all patients following postimplantation hospital discharge.

Results

As of December 2018, 2024 patients were on active follow-up at the center. Of these, 93% of patients were remotely monitored according to the established protocol. The transmission rates were: 5.3/patient-year for pacemakers, 6.0/patient-year for defibrillators, and 14.1/patient-year for loop recorders. Only 21% of transmissions were submitted to the physician for further clinical evaluation, and 3% of transmissions necessitated an unplanned in-hospital visit for further assessment. Clinical events of any type were detected in 39% of transmissions. Overall, the nurses’ total workload was 3596 h per year, that is, 1.95 full-time equivalent, which resulted in 1038 patients/nurse. The total workload for physicians was 526 h per year, that is, 0.29 full-time equivalent. After 1 year on follow-up, most patients judged the service positively and expressed their preference for the new follow-up approach.

Conclusion

A remote follow-up service can be implemented and efficiently managed by nursing staff with minimal physician support. Patients are followed up with greater continuity and seem to appreciate the service.
