Wiederverwendung von Funktionsgruppen im Unikatbau
Authors: Zimmermann Thomas C. , Schmidt Marvin M. 
Published: March 2020

Kurzfassung
Im Serienbau findet bereits umfangreiche Wiederverwendung von Konstruktionslösungen statt, um steigende Komplexität von Produkten beherrschen zu können. Entwicklungsmethoden im Unikatbau sind oft weniger formal ausgeprägt und Synergieeffekte können häufig nicht genutzt werden. In stark regulierten Umfeldern kommen Use-Cases und Funktionen zum Einsatz, um wiederkehrende Features zu identifizieren und so zu Optimierungen in der Systementwicklung, Integration und Absicherung beizutragen.

ABSTRACT
Whitening lotion is a mixture of chemicals or other ingredients with properties that can whiten the
skin or blemish black (brown) on the skin. The use of mercury in whitening lotions can cause a
variety of things, ranging from skin discoloration which can ultimately cause black spots on the
skin, allergies and skin irritation. The using of mercury in high dose can cause permanent brain
damageand cancer. An analysis of mercury content in the whitening lotion brands A, B and C
circulating at market in Padang city has been conducted. Extraction of mercury in the whitening
lotion was done by wet destruction with a concentrated HNO3 solution and concentrated H2SO4 for
2 hours at a temperature of ± 95°C until a clear solution is obtained. The clear solution was
measured by absorption with an Atomic Absorption Spectrophotometer using a mercury hollow
cathode lamp at a wavelength of 253.7 nm. The results of this study were samples of brands A, B
and C detected containing mercury metals with successive levels of 0.3347 μg /g; 0,7917 μg /g and
0,7981 μg/ g. The whitening lotions that circulate in market do not meet the Head of BPOM RI

Background: Automated volumetry software (AVS) has recently become widely available to neuroradiologists. MRI volumetry with AVS may support the diagnosis of dementias by identifying regional atrophy. Moreover, automatic classifiers using machine learning techniques have recently emerged as promising approaches to assist diagnosis. However, the performance of both AVS and automatic classifiers have been evaluated mostly in the artificial setting of research datasets. Objective: Our aim was to evaluate the performance of two AVS and an automatic classifier in the clinical routine condition of a memory clinic. Methods: We studied 239 patients with cognitive troubles from a single memory center cohort. Using clinical routine T1-weighted MRI, we evaluated the classification performance of: 1) univariate volumetry using two AVS (volBrain and Neuroreader™); 2) Support Vector Machine (SVM) automatic classifier, using either the AVS volumes (SVM-AVS), or whole gray matter (SVM-WGM); 3) reading by two neuroradiologists. The performance measure was the balanced diagnostic accuracy. The reference standard was consensus diagnosis by three neurologists using clinical, biological (cerebrospinal fluid) and imaging data and following international criteria. Results: Univariate AVS volumetry provided only moderate accuracies (46% to 71% with hippocampal volume). The accuracy improved when using SVM-AVS classifier (52% to 85%), becoming close to that of SVM-WGM (52 to 90%). Visual classification by neuroradiologists ranged between SVM-AVS and SVM-WGM. Conclusion: In the routine practice of a memory clinic, the use of volumetric measures provided by AVS yields only moderate accuracy. Automatic classifiers can improve accuracy and could be a useful tool to assist diagnosis.

Published: March 2020

Background: Changes in resting state functional connectivity (rs-fc) occur in Alzheimer’s disease (AD), but few longitudinal rs-fc studies have been performed. Most studies focus on single networks and not a global measure of rs-fc. Although the amyloid tau neurodegeneration (AT(N)) framework is increasingly utilized by the AD community, few studies investigated when global rs-fc signature changes occur within this model. Objective: 1) Identify a global rs-fc signature that differentiates cognitively normal (CN) individuals from symptomatic AD. 2) Assess when longitudinal changes in rs-fc occur relative to conversion to symptomatic AD. 3) Compare rs-fc with amyloid, tau, and neurodegeneration biomarkers. Methods: A global rs-fc signature composed of intra-network connections was longitudinally evaluated in a cohort of cognitively normal participants at baseline ( n = 335). Biomarkers, including cerebrospinal fluid (Aβ42 and tau), structural magnetic resonance imaging, and positron emission tomography were obtained. Results: Global rs-fc signature distinguished CN individuals from individuals who developed symptomatic AD. Changes occurred nearly four years before conversion to symptomatic AD. The global rs-fc signature most strongly correlated with markers of neurodegeneration. Conclusion: The global rs-fc signature changes near symptomatic onset and is likely a neurodegenerative biomarker. Rs-fc changes could serve as a biomarker for evaluating potential therapies for symptomatic conversion to AD.
Neurofilament Light Predicts Decline in Attention but Not Episodic Memory in Preclinical Alzheimer’s Disease

Published: March 2020

Background: Cerebrospinal fluid tau and neurofilament light (NfL) are two biomarkers of neurodegeneration in Alzheimer’s disease. Previous reports have shown that the influence of tau on cognitive decline depends on levels of amyloid burden whereas NfL predicts decline independently of amyloid. Most studies use a global cognitive composite as the primary outcome, and it is unknown if critical cognitive domain scores are similarly sensitive to rates of decline due to neurodegeneration. Objective: To examine the unique contribution of amyloid, tau, and NfL to rates of cognitive decline in multiple cognitive composites in a cognitively healthy, middle-aged to older adult cohort. Methods: A total of 255 participants (55% female; mean age = 66.2 years, range = 42.5–86.7 years) completed CSF studies and serial cognitive assessments to measure global cognition, episodic memory, and attentional control. Linear mixed effects models were used to examine rates of change on each composite score as a function of baseline biomarker levels. Results: Total tau predicted decline in attention regardless of amyloid status, but the relationship to global cognition and episodic memory was dependent on amyloid, replicating prior literature. NfL predicted decline in attention and global cognition, but not memory, and this effect was independent of amyloid status. Conclusions: These findings suggest that NfL can be used to monitor cognitive decline in aging and Alzheimer’s disease and that an attentional control composite may be a better outcome for tracking general neurodegenerative effects on cognition.

Published: March 2020

Автор досліджує суспільні відносини у сфері роззброєння, зокрема протимінної діяльності в сучасних умовах, а також аналізує результати Оглядової конференції з питань розмінування, що відбулася 25–29 листопада 2019 року в Осло. У статті розкрито зміст прийнятих Плану дій Осло та Проекту декларації Осло про світ, вільний від мін. Відзначено причини невиконання Україною статті 5 Оттавської конвенції. Висвітлено оцінки критеріїв здатності України до проведення розмінування.
Обґрунтовується зміна змісту виконання міжнародних зобов’язань України із роззброєння до 2014 року, що зумовило сьогодні перегляд правових підходів до забезпечення розмінування. Відзначається, що сфера протимінної діяльності становить самостійний предмет правового регулювання, а також достатність підстав для прийняття окремого закону та подальшого розвитку законодавства у цій сфері.
Метою статті є наукове обґрунтування та визначення правових аспектів роззброєння України, зокрема у сфері протимінної діяльності, шляхом висвітлення положень Конвенції про заборону застосування, накопичення запасів, виробництва і передачі протипіхотних мін та про їхнє знищення 1997 року, а також аналізу стану її виконання Україною у контексті постановки завдань розвитку національного законодавства з означених питань.
Наукова новизна дослідження полягає у представленні автором обґрунтованих результатів та висновків самостійного дослідження стану виконання Україною міжнародних зобов’язань за Оттавською конвенцією, використання яких у законотворчій практиці сприятиме забезпеченню створення адекватного правового регулювання протимінної діяльності на національному рівні, з урахуванням притаманних лише Україні особливостей.
Висновки. Перед Україною постали нові виклики законодавчого оновлення регулювання роззброєння як в цілому, так і з урахуванням фактору воєнної агресії з боку РФ, що триває з 2014 року. На загальному рівні перспективним вбачається розвиток досліджень стану виконання міжнародних зобов’язань із роззброєння з огляду на необхідність забезпечення захисту державного суверенітету. Констатовано відсутність національного стратегічного плану щодо протимінної діяльності, консолідації національної інформаційної системи протимінної діяльності, гендерної політики у цій сфері та відповідних програм, точної інформації щодо площі і місць знаходження протипіхотних мін та звітів про це. Україна поки не встала на шлях реалізації положень Оттавської конвенції.

Published: March 2020

Penggunaan larvasida kimiawi yang digunakan untuk mengontrol aedes aegypti telah menimbulkan populasi yang resistensi, sehingga dibutuhkan dosis yang lebih tinggi. Namun hal ini memiliki efek toksik bagi manusia, hewan, serta lingkungan. Larvasida alami merupakan larvasida yang dibuat dari tanaman yang mempunyai kandungan beracun terhadap serangga pada stadium larva dan tidak menimbulkan efek samping terhadap lingkungan. Penelitian ini bertujuan untuk mengetahui kemampuan dari ekstrak daun mengkudu, daun papaya dan kombinasi keduanya dalam mengendalikan larva Aedes aegypti. Jenis penelitian yang digunakan dalam penelitian ini adalah eksperimental laboratorium dengan desain Rancangan Acak Kelompok (RAK). Objek penelitian adalah larva Aedes aegypti sebanyak 400 larva. Uji dibagi menjadi 4 kelompok dengan dua kali pengulangan. Analisis yang digunakan adalah analisis univariat dan bivariat. Hasil penelitian menunjukkan terdapat perbedaan jumlah kematian larva pada pengulangan I dan II sedangkan rata-rata PH air, suhu air dan kelembaban udara tidak menunjukkan perbedaan yang signifikan. Disimpulkan bahwa kombinasi ekstrak daun mengkudu dan daun pepaya lebih efektif sebagai larvasida alami untuk kematian larva Aedes. Disarankan melakukan analisis probit untuk mendapatkan nilai toksisitas (daya racun) terhadap serangga percobaan dan pengujian terhadap insektisida kimiawi sebagai pembanding (kontrol) terhadap insektisida alami.

Preferensi dalam memilih layanan kesehatan adalah kecenderungan untuk memilih pelayanan kesehatan atau tindakan pengobatan. Kecenderungan ini terkait dengan respon masyarakat terhadap sakit itu sendiri. Mahasiswa perantau asal Adonara pun pastinya mempunyai pilihan tersendiri dalam menentukan pelayanan kesehatan ketika sakit. Penelitian terkait preferensi dalam memilih pelayanan kesehatan sudah banyak dilakukan namun terhadap mahasiswa perantau, masih jarang dilakukan. Tujuan penelitian ini adalah untuk menganalisis faktor yang berhubungan dengan preferensi dalam memilih pelayanan kesehatan pada mahasiswa perantau. Jenis penelitian ini adalah kuantitatif analitik observasional dengan design cross sectional. Populasi dari penelitian ini adalah semua mahasiswa perantau asal Adonara yang kuliah di wilayah Jabodetabek. Hasil penelitian menunjukkan bahwa faktor yang berhubungan dengan preferensi dalam memilih pelayanan kesehatan pada mahasiswa perantau adalah jenis kelamin (Pv=0,008; OR=3,636), sikap (Pv=0,019; OR=3,059) dan motivasi (Pv=0,021; OR=3,744). Sementara Variabel yang tidak berhubungan adalah tingkat pengetahuan (Pv=0,207). Hasil Analisis Multivariat, menunjukkan bahwa variabel yang paling dominan berhubungan dengan preferensi adalah motivasi (Pv=0,019; OR=3,954). Mahasiswa perantau perlu menumbuhkan sikap dan motivasi untuk segera memanfaatkan pelayanan kesehatan ketika sakit agar tidak mengganggu proses study.

Implikasinya adalah kecenderungan untuk segera memanfaatkan pelayanan kesehatan akan semakin tinggi.
Stark Absorption Study of Perylene Doped in a Poly (Methyl Methacrylate) Polymer Film at Different Concentrations
Authors: Ara Anjue Mane , Ahmed Mohammad Kawsar 
Published: March 2020

In this article, electric field modulated absorption (Stark absorption, SA) study of perylene doped in a poly (methyl methacrylate) (PMMA) polymer film at the concentrations of 1.0 mol%, 2.0 mol% and 3.0 mol% is presented. The field effects on the absorption spectra were found to originate mostly from the Stark shift induced by a change in molecular polarizability between the ground and excited states. The analyses of SA spectra with the aid of Liptay formalism yielded essentially the same magnitude of the average change in molecular polarizability (Δα), evaluated for the S0 -> S1 transition, for all the concentrations. This finding implies that Δα of perylene molecule doped in a PMMA film does not depend on concentration. Moreover, the yielded positive Δα for both the preparations implies that SA spectroscopy is an essential technique to probe spectroscopically that perylene possesses larger molecular polarizability in the excited states than in the ground state.

Published: March 2020

Sixteen samples in three categories vegetables, cereals (rice, wheat, maize, pulse) and powdered milk were collected from local markets (Dhaka city) in Bangladesh and analyzed by using High Purity Germanium (HPGe) Detector for the assessment of natural and artificial radioactivity. In vegetables (potato, raw banana, giant taro, red amaranth), the average activity concentrations of 232Th, 226Ra, and 40K were found to be 37.82±11.57, 54.93±9.98 and 617.43±65.69 Bqkg-1 respectively, for cereals (rice, wheat, maize, pulse) 24.01±3.67, 31.46±4.00 and 474.83±27.68 Bqkg-1 respectively and for milk samples 15.01±3.65, 26.73±6.77 and 494.21±38.71 Bqkg-1 respectively. The average values of outdoor annual effective dose were found to be 92.18, 61.19 and 52.37μSvy-1 in vegetables, cereals and milk samples respectively. No artificial radionuclide was found in any of these samples. The average value of radium equivalent activity in all samples was 113.89 Bqkg-1 which was less than maximum permissible value 370 Bqkg-1. The values of external hazard indices for vegetables, cereals and milk samples varied from 0.31 to 0.66, 0.17 to 0.40 and 0.11 to 0.36 respectively which is less than unity in all samples that indicate the non-hazardous nature of the samples. The average values of annual effective ingestion dose rate from foods (for adult) were 274.33 μSvy-1, 533.60μSvy-1, and 132.73μSvy-1for 232Th, 226Ra and 40K respectively. These data would be useful to establish a baseline for natural radioactivity concentrations in food items consumed in Bangladesh.
