Published: March 2021

В настоящее время производство основных видов продуктов питания, как традиционных, так и функциональных, детского, диетического, специализированного, спортивного питания невозможно без применения технологических и функциональных ингредиентов. Среди большого ряда ингредиентов производство белковых продуктов,  пищевых волокон отнесены к приоритетным направлениям для привлечения инвестиций, направленных на точки роста пищевой промышленности в сфере ингредиентов. Источником белка и пищевых волокон являются семена льна. Соотношение аминокислот различной природы в белковом комплексе семян льна  обеспечивает его биологическую активность. Протеины льняного семени могут служить белковыми обогатителями для пищевых продуктов. Пищевые волокна семян льна представляют некрахмальные полисахариды, сосредоточенные в их слизевых клетках. По функциональным свойствам они относятся к пищевым добавкам типа гидроколлоидов. Исследование выполнено с целью определения характеристик порошков, произведенных из льняного сырья с использованием распылительной сушки. Объектами исследований служили белковый концентрат и полисахаридный экстракт. Было установлено, что порошки белкового концентрата и полисахаридного экстракта обладали высокими функциональными свойствами, в частности водоудерживающей, жироудерживающей и эмульгирующей способностями, превышающие аналогичные показатели промышленных соевых белковых концентратов. Цветовые характеристики исследуемых образцов соответствовали цветовой гамме от светло-бежевого до бежевого.  Белковый концентрат и полисахаридный экстракт имели насыпную плотность (кг/м3) 225 и 251, соответственно. Были оценены характеристики прессования порошков белкового концентрата и полисахаридного экстракта, полученных из льняного сырья. Полученные данные свидетельствуют о предраположенности исследуемых ингредиентов к образованию агломератов и формированию структуры в зависимости от параметров технологических процессов производства пищевых продуктов и могут быть использованы в качестве  водо- и жиро-удерживающих агентов, эмульгаторов в пищевых технологиях.

WES Reveals Novel Heterozygous NBAS Gene Mutations Associated with Fanconi Syndrome in a Patient with SOPH Syndrome: Case Report
Authors: JY Thong , Z Li , A Halim , X Wang , M Halim , X Zhai
Published: March 2021

Variations in the NBAS gene is known to cause a spectrum of phenotypes ranging from isolated recurrent acute liver failure (RALF) to a multisystemic presentation known as SOPH syndrome. Patients with SOPH present with optic atrophy, acute liver failure, short stature, and Pelger-Huet anomaly. We report the presence of a novel pair of biallelic heterozygous mutations c.5139-5T>G and c.2203-2A>G in the NBAS gene of a patient with SOPH syndrome. A 9-year-old patient was clinically diagnosed with SOPH following clinical laboratory analyses. Current interventions for managing the disease encompass IVIG, methylprednisolone, calcium, and vitamin D administration. Whole-exome sequencing (WES) results showed two mutations: c.2203-2A>G and c.5139-5T>G, in the NBAS gene, which had not been previously reported. Notably, we hypothesize that NBAS mutations could potentially contribute to the development of Fanconi syndrome, a clinical diagnosis reported in our patient. Our study also supports the renaming of SOPH to SOPHIA to allow early detection and effective treatment.

O envelhecimento populacional é relevante aspecto na atualidade, alcançando os mais diversos espaços sociais, inclusive o cárcere. A revisão buscou identificar por meio da literatura os desafios e significados que permeiam o processo de envelhecimento no contexto prisional. A busca foi realizada nas bases de dados PubMed, Scielo e BVS. Foram incluídos apenas artigos completos cujos temas abordassem o processo de envelhecimento no âmbito carcerário, nos idiomas português, inglês e espanhol, e indexados entre 2010 e 2020. Foram encontrados 366 estudos. Após análise dos títulos e resumos, e a aplicação dos critérios de inclusão estabelecidos, foram selecionadas 06 publicações. Identificou-se que a equipe de custódia não possui preparo para o cuidado com os idosos e necessita de treinamento específico. Constatou-se dificuldades no acesso a cuidados apropriados para presos idosos, o que presume ser improvável o envelhecimento saudável e com sucesso atrás das grades. Verificou-se no acervo literário que o envelhecimento para idosos encarcerados acarreta sentimentos ruins, de finitude e de desvalorização social. Por meio da revisão integrativa, conclui-se que o processo de envelhecimento das pessoas privadas de liberdade sofre influências negativas no contexto prisional pelas próprias fragilidades do sistema, onde as unidades penais não recebem as adaptações necessárias.
PERFORMANCE OF MAHATMA GANDHI NATIONAL RURAL EMPLOYMENT GUARANTEE SCHEME IN KARNATAKA: A SEASONAL WISE ANALYSIS
Authors: Odegouda R T  , Dr. S. B. Nari
Published: March 2021

Rural labours are migrating to the urban areas searching for jobs, because of they don’t get jobs in agricultural lean season and Most of the unorganised sector workers are deprived of basic social security measures, like, health, income, employment etc. In this context, the Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGA) as a fall-back employment source is designed to make significant difference to livelihood security in rural areas especially rural poor. The study mainly focused on four questions like, does MGNREGS has properly used fund by seasonal wise; to know the seasonal wise household demanded and provided for employment; to know the share of employment generation among social groups and dose MGNREGS has created more persondays in drought affected years in Karnataka. In this context the present study an attempt to the Seasonal Variation of Employment Generation and Utilization of Fund under MGNREGS in Karnataka. The study found that Whereas coefficient of variation is less in summer season it is evidently on an average 83 percent of workers are benefited from employment during the summer and Rabi season. As compared to the all financial years, on an average of women generated Persondays was highest 44.50 percent in summer season followed by 43.64 percent in Rabi, but in Kharif season was least 11.85 percent. Similar in all year’s during summer and Rabi season have highest proportion of hundred days work done, but least proportion in Kharif season. The study mainly efforts on rainy season it means south west monsoon period the proportion of average rainfall was highest (486mm in July 2013), but it is continuously declined to 244mm in July 2017. But not much rainfall in other remaining months. The study suggests that the MGNREGS programme works should be season wise planning and timely work distribution for who have demanded for work and also to concentrate on more agriculture related works and awareness in gross root level.

Authors: Düzgün Ali Cemal , İlkeli Ekin , Uluşan Zeynep
Published: March 2021

Venous thromboembolism (VTE) is associated with increased mortality and morbidity in cancer patients, and VTE development is among the most frequent causes of death in cancer patients. In this study, we evaluated the efficacy of enoxaparin and tinzaparin on thrombosis development in 36 cancer patients. Of 36 the cases, 14 were given enoxaparin (single dose, 6000 anti-Xa/0.6 ml, s.c.), and 22 were given tinzaparin (single dose 20.000 IU/0.7 ml, s.c.). The improvement was observed following the treatment in Doppler ultrasonography and the resolution of VTE was clinically detectable. We did not observe any signs of a new thrombus development or bleeding in the patient group. We detected a longer survival time in patients with enoxaparin treatment (p<0.05). We conclude that low-molecular-weight heparins are an efficient treatment method for VTE in cancer patients.
Optimal Time of Extraction Retrievable Inferior Vena Cava Filters in Venous Thromboembolic Treatment: Evidence Based Case Report
Authors: Muradi Akhmadu , Hermansyah Rudi
Published: March 2021

Background: Inferior vena cava (IVC) filters have been proven to be significantly advantageous and clinically efficacious in the prevention of deathly venous thromboembolism, but also carry long-term risks, such as device failure, filter fracture, migration, penetration into adjacent structures, etc. Retrievable filters offer the same degree of protection, and subsequently lower those risk by removing them after they aren’t needed. Unfortunately, increasing use of retrievable filters leads to one alarming trend: there’s massive number of filters that are left for an extended time. Whether the time between deployment and retrieval affects filter’s technical success of retrieval remains questionable. Here is a case of a 45-year old woman who had undergone retrievable IVC filter due to pulmonary embolism risk. The patient only came to clinician for routine follow- up once, one month after deployment. One year later, the patient felt abdominal pain and asked to remove the filter. After one failed attempt, the clinician decided to leave the filter in situ as permanent filter.

Method: Literature searching was conducted in several databases (ScienceDirect, EbscoHost, and ClinicalKey) using specified keywords. Six articles that had been passed exclusion and inclusion criteria, were eventually appraised and extracted.

Results: Of all six articles that are included in this study, there are no standard time of retrieval. Each study provides data regarding their attempted retrieval, successful retrieval, and dwell time. Only two articles (Uberoi et al and Glocker et al) analyze the relationship between time of retrieval and successful retrieval. Uberoi et al claims filter retrieval statistically more successful if the dwell time is less than 9 weeks, whereas Glocker et al states the procedure is considerably more successful within 3-4 months (117 days) after deployment. The reasons of retrieval failure in these studies are varied, including device angulation, filter incorporation with IVC wall, and penetration to IVC wall and adjacent structures, or significant thrombus inside the filter.

Conclusion: There are no standard time of retrieval, but clinicians could follow FDA recommendation by removing the filter when it isn’t necessarily needed. However, a time span of 3-4 months between implantation and retrieval can be respectable choice to make sure the maximum chance at retrieval success.

The paper considers the assessment of the impact of the African component of the policy of the United States of America, the People's Republic of China and the Russian Federation on the national security of these countries. An approach to comparing this influence is proposed, which allows us to identify the priorities of Russia's policy in Africa and other regions of the world. A comparison of the African component of the policy of the states of the “strategic triangle” Russia – China – United States can be used to justify recommendations to the military and political leadership of our country. It is concluded that the African component of the policy of the United States, China and Russia occupies a dominant position in the implementation of the current economic and military policy in the African region.
Stylistic Analysis of Shadab Zeest Hashmi’s Poem “You are chained”
Authors: Muhammad Ramzan  , Dr. Abdul Karim Khan  , Dr. Ihsan Ullah Khan
Published: March 2021

This paper aims at analyzing Shadad Zeest Hashmi’s poem ‘You are chained’ with a special focus on the foreground. The tools of foregrounding i.e. parallelism and deviation are surfaced that attract the attention of the reader for hidden messages related to the socio-political scenario of Pakistan, Kashmir, and India. Thus the miserable plight of the Kashmiris is encompassed through stylistic devices which are peculiar to Hashmi’s poetry. Foregrounding is the tool through which one can analyze a piece of literature having so many deviations and code-switching. The main aim of the study is to bring to the fore the local poets writing in English. The research is based on this intention to strike the attention of new researchers to criticize as well as to appreciate our local poets for their encouragement. On the other hand, research on Pakistani literature in English is an emerging area of investigation that is why, it is hoped, that this paper will prove to be an encouraging step ahead for future scholars.

On the basis of comparative analysis of long - term variations in the number of earthquakes, a number of characteristic features of the seismic regime in various geodynamic settings, including the subduction, collision, riftogenesis and spreading, are established. Among them there is a coordinated synchronous or antiphase change in the number of earthquakes for the regions within a single megastructure, coordinated changes in the activity of earthquakes at different deep levels. The data obtained indicate the systemic unity of the manifestations of the earth's seismicity and allow us to use the method of comparative analysis to identify dynamically connected volumes of the lithosphere.

APPLICATION OF MODERN STRUCTURAL MATERIALS, METHODS AND DETECTORS FOR LOW-BACKGROUND EXPERIMENTS
Authors: Rumyantseva N.S. , Gusev K.N.
Published: March 2021

Good examples of the key tasks of modern non-accelerator physics are the searches for dark matter and neutrinoless double beta decay. The essential requirement for such an experiment is the requirement of a minimal background level. The ways to reduce it are quite obvious and widely used in the ongoing experiments. So, the experiments are located in the underground laboratories, a careful selection of structural materials is carried out, and various techniques for active background suppression are used. However, in order to advance in new generation projects in addition to a serious increase in the detector mass, the significant reduction of the background level (which is already pretty low) is required. Very important irremovable background sources are the structural materials close to the detector(s). In this regard, it is extremely important not only to constantly search for new low-background materials, but also to ensure that radioactive contaminants cannot be introduced at the stage of the required parts production. In this article the results of the successful using of structural parts produced by modern methods from novel low-background materials during the preparation of the new generation ultra-low-background experiment searching for neutrinoless double beta decay are presented.
Global change in the mountains
Authors: Price Martin
Published: March 2021

This report identifies the research and information needs towards a greater understanding of the impacts of interacting global processes on mountain regions. It provides an overview of the European Conference on Environmental and Societal Change in Mountain Regions, which took place in Oxford, UK, in December 1997. Since the Rio Earth Summit in 1992, the importance of mountain regions has been increasingly recognised in science and policy initiatives at all levels. Key themes for research on the interactions of environmental and societal change are: a) carbon and nitrogen cycles, b) biodiversity and protected areas, c) gradual and rapid change in mountain landscapes, d) climatic oscillations and extreme events. Long-term and co-ordinated monitoring is vital for both understanding and management of global change. The development of inventories of data and information sharing must be priorities. Central and Eastern Europe is an area of particular attention. Global change research in mountain regions must be interdisciplinary. Partnership of natural and societal scientists from diverse disciplines are crucial, as is the direct involvement of local people in all stages of research and its application.

Drawing with my Students’ – Development of Clothed Life Drawings among University Fine Art Students. Analysis of Selected Drawings by Second Year Students at Kenyatta University
Authors: Wango Kamau
Published: March 2021

Students of Fine Art are introduced to drawing in their first year and human figure drawing in their second year. It is presumed that they have already had some element of earlier exposure in other levels of prior studies. The objective of human figure drawing or life drawing is to get the students to a level of applied skill where they can be able to draw and utilize their skill in other aspects of self-expression in other disciplines of Art. This is because life drawing is a fundamental requirement in all disciplines of art from basic sketching to detailed paintings. This paper examines selected work of students to determine the extent to which they are able to achieve this objective within the unit prescribed duration of one semester. The paper also seeks to determine whether the work produced meets the standard of drawing required at this level which then enables the students to subsequently embark on other units of drawing moving forward. This is critical since they are required to apply their life drawing skills in other units as a matter of routine individual expression. In this regard, if they are required to draw or paint an imaginative composition, they would be expected to depict human figures which not only fit within the composition and are well executed but also express the students’ ability to interpret themes and formulate subject matter. For the purpose of these exercises and in order to focus solely on the objectives of human figure composition and detailed development, the students were confined to the use of pencil for the layout, shading and detailing of their work. This is because pencil provides a wide range of manoeuvre for this kind of exercise. In this series of drawings, the students used one particular female model which provided them with the opportunity to visually interact with the individual model and be able to study and observe how the life model adjusts to various poses. This was designed to help draw inspiration as well as make the drawing exercises methodical, enjoyable and purposeful.
Behavior of Sand Compaction Columns Installed in Cohesionless Deposits

A critical appraisal of the reviewed literature revealed that there are very limited studies available on the strength characteristics focusing on the load-settlement behavior of sand compaction columns (SCCs) when installed in cohesionless deposits. The method, though contemporary to the reputed stone column technique, is not yet studied rigorously in the available past studies, more precisely on the load-bearing characteristics when compared to the latter. Therefore the present study focuses on studying the behavior of multiple column composite foundation supported by sand compaction columns installed in loose to medium dense sands on a lab-scale numerical model. The study is carried out using commercially available finite element (FE) code 3D PLAXIS. Spacing to diameter ratio (S/D) ranging from 1.5 to 3.5 and initial relative density (RD) from 30 to 60% was adopted to study the changes in the load-settlement behavior of the improved deposit. Extending the FE model to further parametric study, the effect of angle of internal friction of the column sand and diameter of the column on the bearing capacity and settlement characteristics were analysed with and without normalization. From the results obtained, it is found that, for the considered FE model, the improved deposit with 3D spacing between the SCCs behaves distinctly different from all other cases analyzed.

Sigurnosne
službe u Sjevernoj Makedoniji imaju dugu tradiciju, počevši od kraja Drugog
svjetskog rata. U svom razvoju, a posebno od neovisnosti do danas, sigurnosne
službe pretrpjele su nekoliko promjena, neke od njih samo kozmetičke, a neke su
ukinute ili transformirane u nove. Te su promjene bile determinirane povijesnim
i društvenim promjenama s jedne strane, ali i razvojem sigurnosnih prijetnji i
metoda i načina provođenja djela povezanih s terorizmom i drugim hibridnim
prijetnjama, s druge strane. Danas, slijedeći svoje tendencije ka članstvu u
EU, budući da je već postala članicom NATO saveza, Sjeverna Makedonija daje sve od sebe da sigurnosni sektor, a
posebno obavještajne i protuobavještajne službe, podigne na višu razinu i
približi se svijetu sigurnosni standardi. Kao rezultat toga, posljednjih su
godina uspostavljene nove službe i očekuju se promjene u nekim od postojećih
obavještajnih službi.
Experimentelle Untersuchung zum Querkrafttragverhalten von Spannbetonträgern mit geringer Schubbewehrung/Experimental investigation of the shear behavior of post-tensioned beams with a minimum amount of transverse reinforcement
Authors: Kollegger Johann , Huber Tobias , Kromoser Benjamin , Huber Patrik
Published: March 2021

Für bestehende Spannbetonbrückenträger mit geringen Schubbewehrungsgraden kann nach den derzeit gültigen normativen Berechnungsansätzen in Österreich und Deutschland in den meisten Fällen kein ausreichender Querkraftwiderstand nachgewiesen werden. Dies kann vorrangig auf die geänderte Normensituation zurückgeführt werden. Um mehr über das Querkrafttragverhalten dieses Tragwerktyps zu erfahren, wurden vier großformatige Querkraftversuche durchgeführt. Mithilfe der Nahbereichsphotogrammetrie konnte auf Basis von detaillierten Messungen der Kinematik sowie des Verlaufs des kritischen Schubrisses gezeigt werden, dass die Schubtragfähigkeit der Querkraftbewehrung nicht ausreicht, um den Abtrag von Querkräften zu erklären. Darüber hinaus konnte auf Grundlage der markanten Rissöffnung festgestellt werden, dass die Rissverzahnung im Bruchzustand keinen Beitrag zum Querkraftwiderstand liefert. Eine Gegenüberstellung der Versuchsergebnisse mit diversen normativen Bemessungsansätzen bestätigte, dass das Fachwerkmodell mit variabler Druckstrebenneigung aus dem Grunddokument des Eurocode 2 bei weitem nicht imstande ist, die experimentelle Querkrafttragfähigkeit korrekt wiederzugeben. Obwohl mit der dritten Näherungsstufe nach Model Code 2010 deutlich präzisere Vorhersagen der Bruchlasten möglich sind, liefert auch dieser Ansatz noch immer sehr konservative Ergebnisse. Für die Nachrechnung solcher Brückenobjekte bedarf es somit verfeinerter Berechnungsansätze, welche auch dem Beton neben dem Traganteil der Querkraftbewehrung ein Schubtragvermögen zutrauen.
Studien zum Beulverhalten von eng ringversteiften Kreiszylinderschalen unter Axialdruck/Studies on the buckling behavior of closely ring-stiffened cylindrical shells subjected to axial compression
Authors: Pasternak Hartmut , Jäger Andreas
Published: March 2021

Der moderne Stahlbau ist geprägt vom Streben nach effizienten Materialeinsatz und Nachhaltigkeit. Einen Beitrag dazu liefern ringversteifte Behälter, bei denen dünnwandige Bleche und kräftige Ringsteifen zu einem Leichtbauwerk kombiniert werden. Die Bleche zwischen den Ringsteifen sind stark axialbeulgefährdet, jedoch wird die Beulgefährdung durch die Steifen deutlich reduziert. In diesem Aufsatz wird neben einem Ausflug in die Behälterbaupraxis ein Beispiel für dünnwandige, ringversteifte Tanks der Biogasindustrie diskutiert und einem unversteiften Behälter gegenübergestellt. Im Anschluss werden der traglaststeigernde Einfluss der Ringversteifung auf das Axialbeulverhalten der Bleche zwischen den Steifen vorgestellt und Einsparpotenziale aufgezeigt.

 

Abstract Modern steel construction is greatly influenced by the pursuit of building material efficient and sustainable structures. Ring-stiffened shells, that are built as a combination of thin plates with strong ring stiffeners, contribute to this goal. The plates are prone to failure by axial buckling. However, the ring stiffeners greatly reduce the susceptibility to a loss of stability by axial buckling failure. In this article an insight into different types of tank constructions is provided. An example of a very thin walled tank, typical in the biogas industry, is discussed and compared to a non-stiffened variant of the same storage capacity. The beneficial effect of the ring stiffeners on the bearing capacity of the plates between the stiffeners and potential material savings are discussed.
Schadensklassifizierung für Gebäude nach Extremereignissen/Damage classification for buildings subjected to hazardous events
Authors: Stolz Alexander , Roller Christopher , Carstens Stefan , von Ramin Malte
Published: March 2021

Zur Einschätzung von Gebäudeschäden nach möglichen Extrembelastungen infolge außergewöhnlicher Einwirkungen wird ein auf physikalischen Modellen basierendes Ingenieurverfahren vorgestellt, das es erlaubt, auf Grundlage initialer Einzelbauteilschädigungen den zu erwartenden Gesamtgebäudeschaden semi-quantitativ zu beschreiben. Hierzu wurden für verschiedene Bauweisen und Materialien Schadenskurven hergeleitet, die eine graduelle Schädigung des Gebäudes in Abhängigkeit von einem Bauteilschädigungsindex abbilden. Ausgehend von dem Schädigungsgrad der einzelnen Bauteile in Folge eines Extremereignisses, wurden die Schadenskurven mithilfe des Traglastiterationsverfahrens am Modell des Gesamtgebäudes hergeleitet. Für die Bestimmung der jeweiligen Traglast wird die Initialschädigung der Bauteile für das jeweils verwendete FE-Modell über eine Modifizierung der Materialkennlinien abgebildet. Die Gültigkeit dieser Schädigungsfunktion konnte anhand von detaillierten Hydrocode-Simulationen und experimentellen Ergebnissen validiert werden. Gegenüber den bisher üblichen Verfahren, die eine Schadenklassifizierung des Gebäudes auf Grundlage empirisch gewonnener Schadensdaten vornehmen, hat die hier vorgestellte Methode den Vorteil, dass die zum Gesamtschaden führenden Einzelschädigungen nachvollziehbar berechnet und identifiziert werden, um an kritischen Bauteilen eventuell durchführbare Verstärkungsmaßnahmen gezielt und effizient planen zu können.
Verfahren zur langfristigen Sicherheitsbetrachtung von Deponiebauwerken/A method for long-term safety assessment of landfill structures

Published: March 2021

Nachweise der Tragfähigkeit, Gebrauchstauglichkeit und Dauerhaftigkeit durch eine Berechnung, unter anderem mit den Methoden der Baustatik oder Geotechnik, sind unverzichtbarer Bestandteil der Entwurfsarbeit von Bauwerken. Standsicherheitsnachweise als Ergebnis der Tragwerksplanung umfassen die vorgesehene Nutzungs- und Lebensdauer des geplanten Bauwerkes unter Einbeziehung der für den Standort angenommenen und zulässigen Belastungen. Diese Beanspruchungen unterliegen zum Teil großen Streuungen und sind bedingt durch Kraft- und Verformungswirkungen, sowie durch chemische und physikalische Einflüsse. Aus der Gegenüberstellung mit vorhandenen Widerständen resultieren Sicherheitsabstände, die projektbezogen erreicht werden müssen. Dieses Vorgehen aus den traditionellen Ingenieurdisziplinen hat in der Deponietechnik noch nicht umfassend Einzug gehalten. In der Planungsphase werden Aspekte der Betriebstauglichkeit und Wartbarkeit im Hinblick auf die Standsicherheit von technischen Systemen im Betrieb berücksichtigt. Es wird jedoch als Bestandteil der Planung zur langfristigen Umweltverträglichkeit kein Nachweis der Emissionssicherheit der Deponiekonstruktion für die gesamte Lebensdauer gefordert. Der empfohlene Weg ist die auf langfristigen Boden- und Grundwasserschutz bemessene Deponiesicherung unter systematischer Berücksichtigung der Standort- und Milieubedingungen. Folgt man dem grundsätzlichen Vorgehen aus dem Ingenieurbau, kann zuverlässig eine Sicherheitsbetrachtung als Gesamtschau aller Beanspruchungen und Widerstände im Planungsstadium einer Deponiekonstruktion, also nach dem Prinzip Vorsorge, im Einklang mit den Forderungen nach Wirtschaftlichkeit durchgeführt werden.

Die Bestimmung der Rauheit von Bauteiloberflächen stellt eine wichtige Messaufgabe im Bauwesen dar. Vor allem bei der Betoninstandsetzung, im Straßenbau und bei der Herstellung von Stahlbeton-Halbfertigteilen ist die Rauheit – gemessen als Rautiefe – eine wichtige Kenngröße. Zurzeit werden Messungen der Rautiefe mittels volumetrischer Verfahren (Sandflächenverfahren) durchgeführt. Diese bereits seit mehreren Jahrzehnten angewandten Verfahren sind jedoch auf horizontale und wenig geneigte und trockene Oberflächen beschränkt. Darüber hinaus hängen die erzielten Ergebnisse sehr stark von der angewandten Prüfvorschrift, den darin vorgeschriebenen Prüfmitteln und Geräten und dem jeweiligen Anwender ab. Als Alternative zu den volumetrischen Verfahren wurde an der Bundesanstalt für Materialforschung und -prüfung (BAM) ein automatisiertes, laserbasiertes Messverfahren entwickelt, mit dem Rautiefen von Bauteiloberflächen in Anlehnung an bereits standardisierte Verfahren bestimmt werden können. Der vorliegende Beitrag befasst sich zunächst mit den konventionellen Prüfverfahren, beschreibt die wichtigsten Zusammenhänge und zeigt die Grenzen dieser Methoden auf. Im zweiten Teil wird das an der BAM entwickelte Messsystem, als zielführendes Alternativverfahren für die konventionellen Methoden, vorgestellt und dessen Leistungsfähigkeit näher beschrieben.
Rabitzgewölbe Von der Herstellung bis zur statischen Ertüchtigung der Abhänger/Rabitz (plaster on wire mesh) vaults. From construction to rehabilitation

Rabitzgewölbe fanden von 1880 bis 1920 vor allem im deutschsprachigen Raum weite Verbreitung. Dennoch haben diese Konstruktionen in der modernen ingenieurwissenschaftlichen Analyse bisher kaum Beachtung gefunden. Im vorliegenden Beitrag sollen am Beispiel der Pfarrkirche Bad Griesbach Möglichkeiten aufgezeigt werden, um Rabitzgewölbe im Bestand hinreichend zu erfassen und auf Basis des derzeit gültigen Sicherheitsniveaus nachzuweisen, ohne wesentliche Eingriffe in die Bausubstanz vornehmen zu müssen. In diesem Zusammenhang berichten wir auch über Versuchsreihen, die an repräsentativ gewählten Anschlussgeometrien im Maßstab 1:1 durchgeführt wurden, und erläutern Bruchverhalten, Bruchlasten und Widerstandsgrößenermittlung zur Nachweisführung. Abschließend wird die Ausführung der entsprechenden Instandsetzung vorgestellt.
