Modeling, simulation and measurement of radiation exposure using electronic personal dosimeters on realistic and ICRU phantoms
Authors: Fülle D. , Wahl W. 
Published: March 2022

Abstract
Exposure studies with voxel phantoms were carried out to understand the new personal dose measurand Hp(10) measured by personal dosimeters under realistic wearing conditions. Two simulated realistic voxel phantoms and the dosimeter assembly are described in a first step. Conditions such as photon fluence, radiation field geometry, and photon energy for simulating the external photon fields at the realistic model are specified. Person-related effective doses are calculated to evaluate the personal dose. The relation between measured deep personal dose and effective dose is demonstrated and discussed by means of the simulated response function of the dosimeters at realistic phantoms.
Recent trends in radioanalytical purification procedures and application to decommissioning of nuclear facilities
Authors: Schupfner Robert 
Published: March 2022

Abstract
The decommissioning of nuclear facilities demands an optimisation of analytical procedures to determine a variety of radionuclides in a variety of different materials on a wide activity scale ranging from very low to very high activities. Severe analytical problems arise from disadvantageous decay properties of a number of radionuclides. In the following the opportunities and limitations of recently developed analytical and nuclear detection methods are presented which has been applied successfully determining radionuclides like 55Fe, 59Ni, 63Ni, 90Sr, Th, U, Pu, Am, Cm. The applied analytical methods have to fulfil high quality standards including very low lower limits of detection, very high selectivity, sufficient precision and accuracy even in samples containing enhanced amounts of interfering elements. A new powerful tool is the application of collimated in-situ-γ-spectrometry. A recently developed calibration phantom named K-RISK is presented.

Abstract
During attempts to synthesize new platinides in the ternary system Sr–Al–Pt, single crystals of SrAl5Pt3 and Sr2Al16Pt9 were obtained from a reaction of the elements with the nominal composition Sr4Al13Pt9. Both orthorhombic structures were refined based on single crystal x-ray diffraction data (SrAl5Pt3: Pnma, Wyckoff sequence c

Schadensdiagnose an angetriebenen Werkzeugen mittels MEMS-Sensorik
Authors: Brecher Christian , Neus Stephan , Christoffers Daniel 
Published: March 2022

Abstract
Kernthema des vorliegenden Beitrags ist die Schadensdiagnose von angetriebenen Werkzeugen mittels MEMS- (Micro-Electro-Mechanical-Systems) und Piezo-Sensoren. Mithilfe beider Typen werden verschlissene angetriebene Werkzeuge untersucht. Es steht zum einen die Frage im Raum, ob MEMS-Sensoren generell vergleichbare Ergebnisse wie die teureren Piezo-Sensoren liefern. Zum anderen wird untersucht, wie sich unterschiedliche Werkzeuge auf die Signalqualität auswirken. Es zeigt sich, dass der untersuchte MEMS-Ansatz ähnliche Effekte wie der Piezo-Sensor erfasst. Zudem zeigt sich ein Einfluss der Werkzeugmasse und -geometrie. So unterscheiden sich die Amplituden je nach Werkzeug um bis zu 200 Prozent.

Published: March 2022

Abstract
Aufgrund der zunehmenden Variantenvielfalt in der industriellen Montage spielen informatorische Assistenzsysteme eine immer stärkere Rolle zur kognitiven Unterstützung von Mitarbeitenden sowie zur Qualitätssicherung innerhalb von Montageprozessen. Ergänzend bieten physische Assistenzsysteme Potenziale zur Entlastung von Mitarbeitenden bei monotonen und ergonomisch ungünstigen Tätigkeiten. In diesem Beitrag wird ein Vorgehensmodell zur anforderungsorientierten Planung von Montageassistenzsystemen vorgeschlagen und evaluiert, welches – ausgehend von einer methodischen Bedarfserfassung – eine systematische Auswahl von notwendigen Assistenzfunktionen ermöglicht.
Optimierung der Lieferfähigkeit und Feinplanung

Abstract
Bei Aufgabenstellungen des Supply Chain Managements, wie z. B. bedarfsorientierte Sicherheitsbestandsberechnungen oder die Produktionsfeinplanung gegen begrenzte Ressourcen, sind die Variablen so vielfältig, dass konventionelle Berechnungsmethoden – selbst wenn sie vollautomatisch mit voller Datencenter-Rechenleistung angegangen werden – einfach zu viel Zeit in Anspruch nehmen. Künstliche Intelligenz kann in wesentlich kürzerer Zeit bessere Ergebnisse liefern.
Association of serum stromal cell-derived factor 1 levels with EZSCAN score and its derived indicators in patients with type 2 diabetes
Authors: Liu Wang-shu , Hua Ling-yan , Zhu Su-xiang , Xu Feng , Wang Xue-qin , Lu Chun-feng , Su Jian-bin , Qi Feng 
Published: March 2022

Background
The aim of the study was to explore whether plasma stromal cell-derived factor 1 (SDF-1) levels are associated with the EZSCAN score and its derived indicators in patients with type 2 diabetes (T2D).

Methods
From July 2020 to December 2020, a total of 253 patients with T2D were consecutively recruited. Serum SDF-1 levels were measured by sandwich ELISA. EZSCAN test was applied to evaluate the sudomotor function of each patient, and based on the results, EZSCAN score, cardiac autonomic neuropathy risk score (CANRS) and cardiovascular risk score (CVDRS) were calculated by particular algorithms. In addition, other relevant clinical data were also collected.

Results
With increasing tertiles of serum SDF-1 levels, the CANRS and CVDRS significantly increased (both Pfor trend <0.001), while the EZSCAN score significantly decreased (Pfor trend <0.001). Moreover, serum SDF-1 levels were significantly and positively correlated with the CANRS and CVDRS (r = 0.496 and 0.510, respectively, both P  < 0.001), and negatively correlated with the EZSCAN score (r = −0.391, P  < 0.001). Furthermore, multivariate linear regression analyses were constructed, and after adjusting for other clinical covariates, serum SDF-1 levels were independently responsible for EZSCAN score (β = −0.273, t = −3.679, P  < 0.001), CANRS (β = 0.334, t = 5.110, P  < 0.001) and CVDRS (β = 0.191, t = 4.983, P  = 0.003).

Conclusions
SDF-1 levels in serum were independently associated with the EZSCAN score and its derived indicators, such as CANRS and CVDRS in patients with T2D.
COMMODIFICATION OF RELIGIOUS RITUALS: A PORTRAIT OF THE MEANING OF HAJJ AND UMRAH IN INDONESIA
Authors: Fuad Sahlul 
Published: March 2022

Abstract. This article discusses religious behaviour related to Hajj and Umrah which have become a form of commodification of religion. Hajj and Umrah, as two types of religious rituals in Islam, are extensively interrelated with other existing social institutions. Therefore, they have a more complex association compared to other religious rituals. Hajj and Umrah have not only given birth to various meanings for those who perform the rituals, but also become a tourism industry with a wide and promising market share. Hajj and Umrah seem to be able to change other religious behaviours such as the increase of obedience’s intensity in worshiping God. In addition, Hajj and Umrah in Indonesia are not only packaged and marketed as profitable commodities, but also used as tools for criminal acts. Abstrak. Artikel ini membahas tentang perilaku keagamaan terkait haji dan umrah yang telah menjadi bentuk komodifikasi agama. Haji dan Umrah, sebagai dua jenis ritual keagamaan dalam Islam, sangat erat kaitannya dengan pranata sosial lain yang ada. Oleh karena itu, mereka memiliki asosiasi yang lebih kompleks dibandingkan dengan ritual keagamaan lainnya. Haji dan Umrah tidak hanya melahirkan berbagai makna bagi yang menunaikan ibadah haji, tetapi juga menjadi industri pariwisata dengan pangsa pasar yang luas dan menjanjikan. Haji dan Umrah tampaknya mampu mengubah perilaku keagamaan lainnya seperti peningkatan intensitas ketaatan dalam beribadah kepada Allah. Selain itu, haji dan umrah di Indonesia tidak hanya dikemas dan dipasarkan sebagai komoditas yang menguntungkan, tetapi juga digunakan sebagai alat untuk melakukan tindak pidana.

Published: March 2022

OBJECTIVES
Over 6 million pediatric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections have occurred in the United States, but risk factors for infection remain poorly defined. We sought to evaluate the association between asthma and SARS-CoV-2 infection risk among children.

METHODS
We conducted a retrospective cohort study of children 5 to 17 years of age receiving care through the Duke University Health System and who had a Durham County, North Carolina residential address. Children were classified as having asthma using previously validated electronic health record-based definitions. SARS-CoV-2 infections were identified based on positive polymerase chain reaction testing of respiratory samples collected between March 1, 2020, and September 30, 2021. We matched children with asthma 1:1 to children without asthma, using propensity scores and used Poisson regression to evaluate the association between asthma and SARS-CoV-2 infection risk.

RESULTS
Of 46 900 children, 6324 (13.5%) met criteria for asthma. Children with asthma were more likely to be tested for SARS-CoV-2 infection than children without asthma (33.0% vs 20.9%, P &lt; .0001). In a propensity score-matched cohort of 12 648 children, 706 (5.6%) children tested positive for SARS-CoV-2 infection, including 350 (2.8%) children with asthma and 356 (2.8%) children without asthma (risk ratio: 0.98, 95% confidence interval: 0.85–1.13. There was no evidence of effect modification of this association by inhaled corticosteroid prescription, history of severe exacerbation, or comorbid atopic diseases. Only 1 child with asthma required hospitalization for SARS-CoV-2 infection.

CONCLUSIONS
After controlling for factors associated with SARS-CoV-2 testing, we found that children with asthma have a similar SARS-CoV-2 infection risk as children without asthma.
Tradisi Pembacaan Surat Al-Waqi’ah Dan Surat Al-Mulk Di Pondok Pesantren Mambaul Hikam Ii Karanggayam Blitar Jawa Timur
Authors: Husna Lutfatul , Abidin Ahmad Zainal 
Published: March 2022

Tulisan ini menyorot tradisi pembacaan surat al-Wa>qi’ah dan surat al-Mulk yang dilahirkan dari praktik-praktik komunal yang terjadi di daerah Blitar dimana di Pondok Pesantren Mamba’ul Hikam II Karanggayam, Srengat Blitar ini seluruh santri dibiasakan dan terbiasa mengikuti mujahadah yang rutin dilaksanakan setiap hari. Dalam mujahadah tersebut dilaksanakan pembacaan surat al-Wāqi‘ah dan surat al-Mulk. Dengan menggunakan metode deskriptif fenomenologis berdasarkan observasi, wawancara dan dokumentasi dengan analisis pembacaan menggunakan teori sosiologi pengetahuan Karl Mannheim, tulisan ini menemukan bahwa: pertama, tradisi pembacaan Alquran surat al-Wa>qi’ah dan al-Mulk ini dilaksanakan rutin setiap hari karena berkaitan dengan keutamaannya yang besar. Kegiatan pembacaan tersebut diawali dengan bacaan surat al-Fa>tihah sebagai bentuk tawassul. Kedua, pembacaan surat al-Wa>qi’ah dilaksanakan pada sore hari ba’da shalat ashar, dan pembacaan surat al-Mulk di waktu ba’da shalat Subuh. Ketiga, pembacaan terhadap ritual pembacaan surat al-Wa>qi’ah dan surat al-Mulk di pesantren ini menemukan tiga makna penting yakni, makna objektif, yakni bahwasa tradisi pembacaan surat al-Wa>qi’ah dan surat al-Mulk awalnya merupakan peraturan yang sudah ditetapkan sejak lama dengan tujuan ntuk mencetak santri-santri menjadi orang alim dan berilmu; makna ekspresif, dimana ada harapan mendapat kemudahan rezeki sehari-hari, terhindar dari siksa neraka dan mendapatkan ketenangan tersendiri bagi pelakunya; dan makna dokumenter, dimana amaliyah ini menjadi kebiasaan yang menjadikan santri lebih disiplin dalam melakukan aktifitas ritual keagamaan lain.

Introducción: La procrastinación académica puede repercutir negativamente en la formación estudiantil y el desempeño profesional, de allí la necesidad de contar con instrumentos válidos y confiables para su estudio.
Objetivo: Analizar las evidencias de validez y confiabilidad de una escala de procrastinación académica en estudiantes cubanos de Estomatología.
Métodos: Estudio instrumental, transversal y multicéntrico, que incluyó estudiantes de siete universidades cubanas. A partir de un instrumento en español validado en estudiantes peruanos, se realizó un análisis factorial confirmatorio, se utilizó el modelamiento de ecuaciones estructurales y se calculó la consistencia interna con el coeficiente α de Cronbach.
Resultados: Se incluyó a 684 participantes, de los cuales el 63,45 % fueron mujeres y la media de la edad fue 22,0 ± 1,71 años. De la escala inicial de 12 ítems distribuidos en 2 factores, el análisis factorial sugirió eliminar el ítem 5. El modelo final quedó conformado por 11 ítems, 8 para el factor 1 (Autorregulación académica) y 3 para el factor 2 (Postergación de actividades). Se obtuvo un coeficiente α de Cronbach de 0,786 (IC 95 % = 0,75 – 0,81), lo cual indica que la consistencia interna del instrumento es buena.
Conclusiones: Se validó una escala de procrastinación académica de 11 ítems (EPA-11-Odonto), la cual posee evidencias de validez y confiabilidad adecuadas para evaluar el constructo en estudiantes cubanos de Estomatología.

Introduction: Stroke-related factors seem to have significant effects on sexual functions in physical, biological, and psychosocial areas. This study aims to evaluate the factors affecting the sexual functions of patients after stroke.
Material- methods: This study consisted of 51 (53.1%) male and 45 (46.9%) female patients. Socio -demographics and clinical features of the patients were documented. Sexual functions evaluated with Arizona Sexual Experiences Scale (ASES), International Index of Erectile function (IIEF) and Female Sexual Function Index (FSFI).
Results: The mean age of men and women were 57.76±7.57, and 60.13±12.71 years, respectively. When the ASES cut-off point was 11, we found that 88.5% of the participants (84.3% in men and 93.3% in women) had sexual dysfunction. There was no significant difference between the frequency of sexual dysfunction in women and men (p=0.166, Pearson Chi-square Test). According to univariate ANOVA results, age (p=0.028) and BDI (p
On the influence of profession on the expression of epileptic seizures
Authors: Sergeev Leonid A. 
Published: March 2022

Epilepsy is not always expressed by well-known characteristic attacks of the disease - convulsions, loss of consciousness, amnesia, etc. It can rather be said that this is one of the forms of mental illness that is very diverse and capricious in its manifestations.
In this suffering, of great public, legal, and also scientific interest are those forms of it, which, along with ordinary epileptic seizures, are expressed in any special actions, sometimes in quite simple and completely incoherent, and other times in more complex and even criminal ones. One patient, for example, during a conversation suddenly begins to whirl or sing, or, abruptly breaking off the conversation, immediately switches to another topic, another, without any reason, exposes his body, shows the genitals and the like.
About the motor nerves of the heart
Authors: Polumordvinov Dmitry V. 
Published: March 2022

Are there nerves whose irritation can cause the heart to contract again after it has stopped?
Modern physiology does not have sufficient material to give a definite answer to this question, neither in the negative sense, nor, still less, in the positive sense.
The most developed and substantiated is the view expressed by the head of the myogenic school Gaskell): such nerves do not exist, or at least we do not know a single fact that would speak for their existence.
M. Bertolotti About cross skin reflexes. And propos des reflexes cutanes croises. - Revue neurol, 1909, № 2

Published: March 2022

In the author's opinion, skin reflexes are generally of little importance for the semiotics of nervous diseases.
The cross-skin reflexes studied by Kluppel and Weil are also not worthy of deep study. They serve only as an indicator of the large spread of the reflexogenic area and correspond to long-established physiological laws, according to which skin reflexes are considered as a protective act.
Zingerle. To the pathological anatomy of dementia praecox. Zur pathologischen Anatomie der dementia praecox. Monatsch. f. Psych. and Neurology. bd. XXVII, S. 285 (1910)
Authors: Likhnitsky Vitaly N. 
Published: March 2022

The author describes in detail the changes in the central nervous system that he found in the case of dementia praecox catatonica. Comparing the changes found by him with those that were previously described by various researchers, Zingerle comes to the conclusion that with dementia praecox we are dealing with a diffuse process that captures all elements of the central nervous system. The nerve cells and fibers of the gray matter of the brain suffer most in this case; the elements of the neuroglia also turn out to be changed, and only a part of these changes can be considered a reaction to the destruction of the nervous tissue; so, in the circumference of large and small vessels of the white matter of the brain, where it is not possible to detect the degeneration of nerve fibers, one can often find a clearly expressed growth of neuroglia.
A characteristic feature of dementia praecox, in contrast to progressive paralysis, is the absence of any significant changes in the vessels of the brain or its membranes.
L. Valkovsky. To the question of hysterical fever. — New in medicine. 1910 № 13 - № 14
Authors: Baklushinsky Ivan D. 
Published: March 2022

Having collected the literature on this subject, the author describes a case of an increase in t to a paradoxical height of 46, accompanied by purely hysterical symptoms. With appropriate treatment, t soon leveled off to normal, and at the same time other signs of the disease disappeared: hemiplegia, contractures, and a violently delusional state. Based on the described case and others that he had to observe, the author notes the following features of hysterical fever: 1) its complete indifference to antipyretics; 2) it can last for a long time, for whole months, but it can last only a few hours; 3) the overall economy of the organism does not suffer at all, or very little; 4) is often observed och. low beat. in. urine; t is different, in different places; or may be increased only at the time of measurement and at the place of measurement; 6) pulse rate does not correspond to t; 7) can reach very high levels of 44-46; 8) appears and disappears often suddenly.
The author explains the paradoxicality of t (its height, suddenness of appearance, etc.) by the fact that its cause lies in the functional disorder of that part of the central nervous system that is in charge of heat regulation in the body.
Arndt. Glycosuria in alcoholic delirium. Ueber die Glycosurie der Alkoholdelironten. — Monatsch. fur Psych. and Neurol. bd. XXVII, S. 222 (1910)
Authors: Likhnitsky Vitaly N. 
Published: March 2022

The author made, for a more or less long time, an examination of the urine for sugar in 194 alcoholics. He divided all his patients into 3 groups; he attributed 99 cases of delirium potatorium to the first; to the 2nd26 cases of delirium pototorium abortivum, in which delusional phenomena were expressed to a slight degree, and finally to the 3rd69 cases of alcoholismus chronicus without delirium.
The presence of sugar in the urine was noted in 30% of cases of the 1st group - delirium potatorium, in 14% - of delirium potatorium obortivum and in 30.4% of cases of the 3rd group - alcoholi'smus chronicus.
Analyzing the data obtained by him, the author notes that in alcoholic delirium, glucosuria is not always post delirious (postdelirise Glykosurie), as Vaitapp claims. So, in 2/3 of patients belonging to the 1st group, the presence of sugar was detected some time before the onset of the crisis.
The amount of sugar fluctuated between 0.2% and 0.4%, only in 4 cases was more than 0.5%.
