Custodial Single Fathers before and during the COVID-19 Crisis: Work, Care, and Well-Being
Authors: Iztayeva Aimzhan
Published: March 2021

As both paid and unpaid work were disrupted during the COVID-19 crisis, the two roles that working custodial single fathers occupy—breadwinners and caregivers—have intensified significantly. Using two independent sets of interviews, this study examines how custodial single fathers navigated work and caregiving responsibilities prior to COVID-19 and compares them to the experiences of single fathers interviewed during the pandemic. The findings are organized into three key themes. First, men with white-collar jobs experienced less work-family conflict than men with blue-collar jobs. The COVID-19 crisis further widened this divide as lack of flexibility put men with blue-collar jobs in a precarious position in the labor market. Second, the way single fathers arranged childcare varied with the availability of extended family and the coparenting relationship with the child(ren)’s mother. The pandemic significantly complicated these arrangements by removing men’s access to extended family and intensifying already conflicted coparenting relationships. Finally, prior to the pandemic, many single fathers struggled with lack of leisure time and diminished social support networks that shrunk with their initial break from their child(ren)’s mother. The resulting feelings of fatigue and loneliness seeped into men’s psychological well-being. COVID-19 and related social distancing measures further exacerbated single fathers’ isolation.

Ensuring the stability of vaccines is crucial to successfully performing global immunization programs. Outer Membrane Vesicles (OMV) are receiving great attention as vaccine platforms. OMV are complex molecules and few data have been collected so far on their stability. OMV produced by bacteria, genetically modified to increase their spontaneous release, simplifying their production, are also known as Generalized Modules for Membrane Antigens (GMMA). We have performed accelerated stability studies on GMMA from different pathogens and verified the ability of physico-chemical and immunological methods to detect possible changes. High-temperature conditions (100 °C for 40 min) did not affect GMMA stability and immunogenicity in mice, in contrast to the effect of milder temperatures for a longer period of time (37 °C or 50 °C for 4 weeks). We identified critical quality attributes to monitor during stability assessment that could impact vaccine efficacy. In particular, specific recognition of antigens by monoclonal antibodies through competitive ELISA assays may replace in vivo tests for the potency assessment of GMMA-based vaccines.
Treatment Strategy for Perianal Fistulas in Crohn Disease Patients: The Surgeon’s Point of View
Authors: Lee Jong Lyul , Yoon Yong Sik , Yu Chang Sik
Published: March 2021

Perianal fistula is a frequent complication and one of the subclassifications of Crohn disease (CD). It is the most commonly observed symptomatic condition by colorectal surgeons. Accurately classifying a perianal fistula is the initial step in its management in CD patients. Surgical management is selected based on the type of perianal fistula and the presence of rectal inflammation; it includes fistulotomy, fistulectomy, seton procedure, fistula plug insertion, video-assisted ablation of the fistulous tract, stem cell therapy, and proctectomy with stoma creation. Perianal fistulas are also managed medically, such as antibiotics, immunomodulators, and biologics including anti-tumor necrosis factor-alpha agents. The current standard treatment of choice for perianal fistula in CD patients is the multidisciplinary approach combining surgical and medical management; however, the rate of long-term remission is low and is reported to be 50% at most. Therefore, the optimum management strategy for perianal fistulas associated with CD remains controversial. Currently, the goal of management for CD-related perianal fistulas are controlling symptoms and maintaining long-term anal function without proctectomy, while monitoring progression to anorectal carcinoma. This review evaluates perianal fistula in CD patients and determines the optimal surgical management strategy based on recent evidence.
Protección de la niñez contra la violencia sexual: Educomunicación, prevención y transformación social
Authors: Dávila Navarro Edgar
Published: March 2021

El presente estudio tiene como objetivo identificar procesos educomunicacionales para la prevención de la violencia sexual en niñas y niños en el marco del proyecto “Protección e Igualdad de Género”, impulsado por el organismo no gubernamental Plan International. Esta experiencia fue implementada de junio a diciembre de 2018 en los municipios de Achacachi y Jesús de Machaca (La Paz), Padcaya y San Lorenzo (Tarija), Buena Vista y El Torno (Santa Cruz) y, por último, en Tarabuco y Zudañez (Chuquisaca). La presente investigación presenta al campo de la educomunicación como una herramienta capaz de generar procesos de transformación social (Aparici, 2003) –en este caso– en beneficio y protección de niñas y niños.

El enfoque metodológico del estudio es cualitativo, se aplicaron entrevistas en profundidad y grupos focales a madres, padres, niñas y niños, con el fin de recoger información descriptiva que permita explicar el fenómeno. Los resultados muestran que tanto niñas como niños son capaces de identificar señales de violencia y denunciar cualquier acción que viole su derecho a la protección. El análisis que se expone a continuación contribuye al debate sobre el desarrollo de competencias educomunicativas, con el fin de construir un ambiente favorable para la autoprotección y protección de la niñez y, al mismo tiempo, verifica que las poblaciones estudiadas son capaces de prevenir y reducir hechos violentos a través de procesos educomunicativos.

Published: March 2021

Las herramientas de teledetección son clave para el monitoreo de biomasa y carbono en bosques, importantes para mitigar el cambio climático. Se estimó la biomasa aérea y carbono a través de teledetección en bosques alto-andinos del Santuario de Fauna y Flora Iguaque (SFFI) de Boyacá, Colombia. Se establecieron 23 parcelas temporales de muestreo (PTM) de 250 m2 y se midieron los árboles con diámetro a la altura del pecho (dap) ≥ 10 cm. La biomasa aérea se estimó con una ecuación alométrica y se correlacionó con tres índices de vegetación (NDVI, SAVI y EVI) obtenidos de dos imágenes del satélite LANDSAT 8 OLI en época seca y lluviosa (2016). Se probraron modelos lineales para estimar la biomasa en función del índice de vegetación y se estimó el carbono. Los bosques del SFFI almacenaron 30 t C/ha en biomasa aérea, y el mejor modelo se basó en el NDVI de la época seca (R2aj = 0,79). Se confeccionaron mapas con la distrribución de biomasa y carbono. Los bosques del SSFI han removido de la atmósfera 164 Gg CO2, los cuales podrían volver a emitirse en caso de no conservarse. Las áreas con mayor biomasa y carbono estuvieron principalmente en el suroeste y norte del SFFI. Con este estudio se hace una primera aproximación del patrón de distribución de la biomasa aérea y carbono con resolución de 30 m. Se ratifica el uso de datos de sensores remotos como insumo primordial para el monitoreo de proyectos de carbono en ecosistemas forestales.

Ante la pandemia COVID 19, declarada en marzo de 2020 por la Organización Mundial de la Salud (OMS), desde la Asociación Colombiana de Hematología y Oncología (ACHO) hemos venido emitiendo comunicaciones destinadas a orientar a los profesionales de la salud implicados en el tratamiento de pacientes hematológicos y oncológicos. Consideramos importante realizar una nueva actualización dada la fase de mitigación de la pandemia que actualmente estamos enfrentando y ante el planteamiento gubernamental de desdescalonamiento progresivo, de la cuarentena.Estas recomendaciones no pretenden imponer una conducta única pues entendemos que cada caso es particular y debe actuarse individualizando a cada situación específica. Están basadas en documentos emitidos por asociaciones científicas oncológicas y hematológicas reconocidas y son susceptibles de sufrir modificaciones a medida que se disponga de mayor información.
Extensión universitaria con jóvenes en conflicto con la ley penal
Authors:   , Urtubey Federico Eduardo
Published: March 2021

La presente tesis de doctorado tiene por objetivo analizar el desarrollo de las intervenciones de dos equipos de extensión universitaria de la Facultad de Bellas Artes (Universidad Nacional de La Plata) realizadas con jóvenes en conflicto con la ley penal, en dos dispositivos de encierro punitivo del Sistema de Responsabilidad Penal Juvenil de la provincia de Buenos Aires, específicamente en la ciudad de La Plata, y que se llevaron a cabo entre los años 2018 y 2019. En los últimos quince años se instrumentaron reformas legales e institucionales, tanto a nivel provincial como nacional, destinadas a proveer un nuevo marco normativo en relación con la infancia y la juventud en el sistema penal. En este marco, las medidas de privación de la libertad dictadas sobre jóvenes procesados penalmente, no sólo se proclaman como de ultima ratio sino que también tienen como sustrato un fin “socio educativo”. Teniendo en cuenta entonces esta particularidad de las instituciones penales, como tributarias de un discurso protectorio de la socio-educación, el propósito de esta investigación es analizar cómo se da el despliegue de experiencias de extensión universitaria, es decir de educación no formal, en el marco de los dispositivos de privación de la libertad. De tal manera, se propone indagar los procesos de ingreso de los equipos de extensión a las instituciones de encierro y los primeros encuentros con los jóvenes, la producción del espacio carcelario y las prácticas docentes en el encierro, como las dimensiones de análisis que pueden propiciar la lectura de tensiones y complejidades en el despliegue de experiencias educativas en el marco de dispositivos de encierro punitivo, que también poseen una finalidad educativa, ligada históricamente a los fundamentos correccionalistas de los espacios de encierro. Esta tesis se asienta en el campo de estudios de la sociología penal juvenil, y en el sub campo de la educación en contextos de encierro. La investigación que le sirvió de base planteó un diseño metodológico de carácter cualitativo y un estudio de casos múltiple, de dos casos, combinando para ello distintas técnicas, tal como la observación participante y no participante, entrevistas, focus group y análisis de documentos.
MENGHASILKAN KEUNGGULAN BERKELANJUTAN MELALUI MANEJEMEN BUDAYA KERJA “AMANU” DI UNIVERSITAS ISLAM JEMBER
Authors: Halid Ahmad
Published: March 2021

Lembaga pendidikan Islam mencapai kesuksesan kerja bisa melalui membangun orang-orang (kepribadian) secara fundamental yaitu mengubah pola pikir tentang bagaimana tenaga kerja dan sikap hubungan kerjasama dengan baik. Dua hal ini berarti mencapai kesuksesan kerja dengan bekerjasama dengan orang lain disertai dengan iman dan amal baik, justru bukan dengan cara mengganti tenaga kerja lama dibuang dan tenaga kerja baru difungsikan atau berusaha membatasi ruang lingkup kegiatan mereka, pengawasan ketat pada mereka dan dekti kepada mereka. Itu cara-cara kuno yang tidak produktif. Dengan demikian budaya kerja yang menghasilkan keunggulan kompetitif (competitive advantage) yang berkelanjutan (sustainable) adalah manajemen yang menggunakan budaya kerja “amanu”. Metode penelitian ini menggunakan metode kualitatif dengan analisis pada temuan. Pengumpulan data menggunakan observasi, interview dan dokumentasi. Keampuhan budaya kerja “amanu” baik secara teori maupun praktik telah terbukti menghasilkan keunggulan competitive yang berkelanjutan dalam suatu lembaga pendidikan Islam atau perusahaan.

Planar head wave induced by pulsed laser ablation in liquid
Authors: Nguyen Thao Thi Phuong , Tanabe-Yamagishi Rie , Ito Yoshiro
Published: March 2021

We studied the dynamics of nanosecond-pulsed laser ablation of graphite-coated and black-paint-coated targets in liquids using a custom-designed time-resolved photoelasticity imaging technique. We presented the first demonstration of a planar head wave that was almost parallel to the target surface. In the solid, we observed a planar stress wave that was a counterpart of the planar head wave. This planar stress wave distorted the typical stress distribution induced by pulsed laser ablation in liquid. The planar head wave and stress wave traveled at the acoustic speed in the corresponding medium. These wavefronts were stronger as the number of shots increased.
THEORISING THE TREASURY SINGLE ACCOUNT (TSA) IN NIGERIA
Authors: Okerekeoti Chinedu U. , Okoye Emma I.
Published: March 2021

Successive governments in Nigeria have continued to operate multiple accounts for the collection and disbursing of government revenues in flagrant disregard to the provision of the constitution which requires that all government revenues be remitted into a single account. Treasury Single Account (TSA) came as a quick fix to regulating the level of accountability and transparency in the financial resources of the government of the country. Treasury Single Account (TSA) is a unified structure of government bank accounts enabling consolidation and optimal utilization of government cash resources. Through this bank account or set of linked bank accounts, the government transacts all its receipts and payments and gets a consolidated view of its cash position at any given time. However, this paper theoretically examined Treasury Single Account in Nigeria with a view to providing the way forward for the country. In this paper, we proposed that government should engage in massive public enlightenment about the importance of the policy at all levels. Also, government should adhere to the provisions of Section 162(1) of the Constitution of the Federal Republic of Nigeria (as amended) for the maintenance of Federation accounts and avoid using private contractors (SystemSpecs-Remita). Though Section 162(1) has made provisions for maintenance of Federation accounts, the legislature should look inwards and address the operational details. Furthermore, government should overhaul the capacity of the Federal Ministry of Finance and the CBN to cope with challenges associated with enforcement of the provisions of the TSA.
COOPERATIVE SOCIETY AS AN ENTREPRENEURSHIP VEHICLE FOR ACTUALISING SUSTAINABLE DEVELOPMENT GOALS: A CASE STUDY OF OSUN STATE
Authors: Jiboye T. F.
Published: March 2021

Studies have affirmed that restructuring for sustainable development is a process involving three essential elements; feasible industrial growth to fulfil basic socio-economic needs; ensuring maximum development of human resources and achieving greater socio justice through a more equitable income distribution. Unfortunately, none of these is satisfactorily manifesting in African nations. In Nigeria, unemployment rate is increasing among the youth and young graduates. Globally, cooperatives societies have become well appreciated as a strong vehicle for promoting economic empowerment particularly among the youth and other vulnerable and marginalised groups. This will be a vehicle to eradicate poverty among the youth thereby fulfilling the first Sustainable Development Goal (SDG). This study examined the contributions of cooperatives societies to poverty eradication among members and national development; investigated how cooperative societies can be better positioned to achieve the Sustainable Development Goals in Nigeria; and determined the factors affecting the performance of cooperatives in Nigeria. Two thousand Nine Hundred and seventy-two respondents from all 1,486 cooperative societies in Osun State were sampled. Result showed that cooperative societies have ability for economic significance, employment creation, income generation, poverty reduction, environmental sustainability and institutional capacity building. The paper concluded that cooperative societies, if well harnessed, could be used to make local entrepreneurs have access to finance and thereby eradicating poverty and so fulfil goal one of the sustainable development goals.
A Functionally Separate Autoencoder
Authors: Wei Jinxin
Published: March 2021

According to kids’ learning process, an auto-encoder is designed which can be split into two parts. The two parts can work well separately.The top half is an abstract network which is trained by supervised learning and can be used to classify and regress. The bottom half is a concrete network which is accomplished by inverse function and trained by self-supervised learning. It can generate the input of abstract network from concept or label. The network can achieve its intended functionality through testing by mnist dataset and convolution neural network. Round function is added between the abstract network and concrete network in order to get the the representative generation of class. The generation ability  can be increased by adding jump connection and negative feedback. At last, the characteristics of the network is discussed. The input can be changed to any form by encoder and then change it back by decoder through inverse function. The concrete network can be seen as the memory stored by the parameters. Lethe is that when new knowledge input, the training process makes the parameters change.

Authors: Troitzsch Sebastian , Zhang Kai , Massier Tobias , Hamacher Thomas
Published: March 2021

To economically dispatch distributed energy resources (DERs) while addressing operational concerns of the electric grid, distribution locational marginal price (DLMP)-based market frameworks have been formulated for the electric distribution grid. This paper proposes to extend this methodology to thermal grids, i.e. district heating or cooling systems, and presents a market-clearing mechanism based on the alternating direction method of multipliers (ADMM) for coordinating between thermal grid, electric grid and DER operation. The ability of the proposed mechanism to achieve the market equilibrium for a combined thermal and electric grid is demonstrated for a test case with 22 flexible loads (FLs).

Length weight relationship and Fulton’s condition factor of Macrobrachium assamense peninsularie in Khoh tributary of Ram Ganga from Garhwal Himalaya, Uttarakhand, India
Authors: Rana Anita Rawat , Kumar Koshal
Published: March 2021

Macrobrachium assamense peninsularie length-weight relationship and Fulton’s condition factor was studied in Khoh tributary of Ram Ganga in the Garhwal Himalaya region of Uttarakhand for the period of one year from March 2009-Feb 2010. A strong positive relationship was observed between the length and weight in both the sexes (male and female) (b<3). Also when data was pooled, the growth was allometric (b<3). The values obtained from the length/weight relationship (LWR) showed that there was a high and significant correlation between the total length and weight after using the t-test for the significance of correlation.The highest correlation coefficient ‘r’ =0.94 i.e strong association between length and weight was observed. This means that as the length of the prawn increases the weight increases in the same proportion. Coefficient of determination r2 was also high (0.88) which indicated that the model used for the analysis fits the data, confirming the fitness of the model. The Fulton’s condition factor “K” was recorded highest (K = 2.0603) in March and lowest (K = 1.6195) in May in Male while in female, the condition factor (K = 2.1038) was highest in August and lowest (K = 1.5345) in October. The condition factor “K” ranges from 1.6195 to 2.0603 in male and 1.5345 to 2.1038 in female. It means the condition factor was sex and season dependent. The difference in condition factors in male and female may be attributed to the presence of ovigerous female, environmental conditions and changes in feeding intensity.

Published: March 2021

Berginia ligulata popularly known as paashaanbhed belongs to family Saxifragaceae. The present study was designed to screen out various phytoconstituents present in the roots of Berginia ligulata and further its antimicrobial activity against human pathogenic bacteria. For this roots of the plant were shade dried, powdered and extracted using different solvents in increasing order of polarity i.e. petroleum ether, diethyl ether, acetone, ethanol and methanol respectively. Preliminary phytochemical screening of the extracts revealed the presence of steroids, terpenoids, alkaloids, tannins, flavanoids, glycosides and carbohydrates. The presence of these bioactive constituents is associated with the antimicrobial activity of the plant. Antimicrobial activity of extracts was performed by disc diffusion method at a concentration of 100% and 50% (w/v) against five bacterial strains. The maximum antimicrobial activity was found in ethanol extract followed by acetone, methanol, diethyl ether and least in petroleum ether extract respectively. Ethanol extract revealed broad spectrum of inhibition against S. sureus and P. aeruginosa.

ANALYTICAL SOLUTIONS OF COUPLED NONLINEAR SCHRODINGER EQUATIONS FOR TWO NON LINEARLY INTERACTING STOKES WAVE TRAINS OVER INFINITE DEPTH
Authors: Manna S. , Dhar A.K.
Published: March 2021

An attempt to find the exact analytical solutions of the two coupled nonlinear Schrodinger equations of 3rd order occurring from the oblique interaction of two capillary gravity wave trains in the case of crossing sea states in deep water is the main premise of the present paper. The solutions obtained here are due to the nonlinear interaction of two Stokes wave trains in one spatial dimension. Graphs have been plotted to investigate the influence of capillarity on the amplitudes of such wave trains. From 3D figures it has been observed that the capillarity has diminishing influence on the amplitudes of the either wave packet.

Therefore, this study aims to analyze the investment in the Banten region in order to obtain a strategy that can alleviate unemployment problems. The research was conducted through a qualitative descriptive approach carried out from August to November 2019. In addition to being based on secondary data obtained from legitimate institutions, to strengthen the results of the analysis, focus group discussions were carried out involving related stakeholders. The results showed that in terms of the distribution of investment in each district/ city, proportion of investment that comes from FDI and DDI or even government spending is dominated by the North Banten and Central Banten regions. So far, the sectors that have become the priority of investors are electricity, gas and water, transportation, warehousing, and telecommunications, which have relatively few workers. Increasing investment in the agribusiness sector is an alternative for efforts to accelerate the reduction in the unemployment rate in Banten Province. Various agribusiness sub-systems ranging from upstream, on-farm agribusiness, downstream agribusiness and agribusiness service provider sub-systems will absorb a lot of labor if realized

Prozessdigitalisierung im Rahmen der BIM-Implementierung in einem Kleinstunternehmen/Process Digitization for BIM Implementation in a Microenterprise
Authors: Sharmak Walter
Published: March 2021

Das Bauwerksinformationsmanagement (BIM) strebt die strukturierte Digitalisierung aller notwendigen Daten und ihre IT-unterstützte Verwendung über den gesamten Lebenszyklus des Bauwerks an. Die derzeitigen Initiativen zur Entwicklung von BIM-Richtlinien für die Bauprozesse konzentrieren sich auf die Modellierung der chronologischen Sequenz sowie auf die Kommunikation im Big-BIM-Bereich, ohne sich mit der Art und Weise der Erhöhung ihres Digitalisierungsgrades der Prozesse zu beschäftigen. Eine Herausforderung für die deutsche Bauindustrie, die sich durch einen relativ niedrigen digitalen Index auszeichnet, besteht darin, nicht nur einzelne Bauaufgaben, sondern komplette Bauprozesse durch IT-Lösungen zu unterstützen.

 

Besonders schwierig ist für Kleinstunternehmen ein Technologiewandel, wie die Einführung der BIM-Methode, da sie kaum Ressourcen (Budget und Personal) für neue IT-Entwicklungen haben.

 

In diesem Beitrag wird eine Übersicht über die Digitalisierung in der aktuellen Baupraxis in Deutschland gegeben. Ferner wird über die vorhandenen nationalen und internationalen BIM-Richtlinien der Bauprozesse berichtet.

 

Anschließend wird eine exemplarische Nutzung der GPM-Methoden (Geschäftsprozessmanagement) zur IT-Unterstützung und zur Steigerung der Digitalisierung beispielhafter Informationsprozesse in einem kleinen Architekturbüro vorgestellt.

 

Darüber hinaus werden Empfehlungen für die erfolgreiche Digitalisierung der Bauprozesse im Rahmen der BIM-Methode in Deutschland benannt.

Es werden derzeit deutliche Fortschritte im Bereich intelligenter Gebäudefassaden gemacht, in der Regel durch die Kombination von Glas und Metall. Im Rahmen des europäischen RFCS-Projekts „S+G“ (Innovative Steel Glass composite structures for high-performance building skins [1]), wurden Stahl-Glas-Verbundsysteme für Fassaden unter Einsatz von Klebverbindungen entwickelt, die freiformende und transparente Verkleidungen von Fassaden und Dächern ermöglichen. Dabei wurden kaltverformte Stahl-Glas-Elemente in Form eines hyperbolischen Paraboloids entworfen, bei denen die Glasscheibe über eine elastische Klebung mit einem Metallrahmen verbunden ist. Schwerpunkte waren unter anderem die Durchführung und numerische Simulation von Bauteilversuchen mit drei verschiedenen Versuchskörpertypen, um das Stahl-Glas-Verbundsystem mit verschiedenen Klebstoffen unter verschiedenen Belastungen zu untersuchen. Der Artikel gibt einen Überblick über die wichtigsten Ergebnisse. Sie zeigen das Potenzial auf, das geklebte kaltverformte Stahl-Glas-Verbundsysteme als Fassadenelemente bieten.
Ermittlung bemessungsrelevanter Kenngrößen an Holzbalken mit Ausklinkungen/Determination of design-relevant parameters on wooden beams with notches
Authors: Huber C. , Deix K.
Published: March 2021

Insbesondere bei Biegeträgern im Ingenieurholzbau mit Ausklinkungen und Öffnungen, geneigtem Obergurt und im Bereich von Queranschlüssen steht die Zugspannung quer zur Holzfaserrichtung als bemessungsrelevante Größe im Vordergrund. In diesen Fällen bestimmt die vergleichsweise geringe Querzugfestigkeit die Grenzen der Tragfähigkeit der Konstruktion. Für Holz liegen diesbezüglich verschiedene, zum Teil widersprüchliche Angaben auf Basis von sehr unterschiedlichen, in einem Großteil der Fälle einaxialen Bestimmungsmethoden vor. Als Ergänzung hierzu und mit Hinblick auf eine möglichst sichere Bemessung von querzugbeanspruchten Strukturen erfolgten versuchstechnische und rechnerische Untersuchungen auf Basis von 50 Kleinbiegeproben (Fichtenholz im Vierpunktbiegeversuch) mit unterschiedlichen Ausklinkungen in Feldmitte. Bestimmt wurden die äußere Lastaufnahmefähigkeit, das Durchbiegungsverhalten sowie das Dehnungs- und Rissverhalten im kritischen Eckbereich der Öffnungen. Mittels eines mehrdimensionalen Bruchkriteriums wurden anhand der gemessenen Bruchlasten die Querzugfestigkeiten rückgerechnet. Aufgrund der speziellen Probenform liefern die Messungen auch Aussagen über die globale Lastkapazität von ausgeklinkten Trägern in Kleinformat, wozu es in der Literatur auch ein entsprechendes Bemessungsverfahren gibt. Es zeigten sich, dass das dort beschriebene Bemessungsverfahren auf globalem Lastniveau die messtechnisch ermittelten Kapazitäten maßgebend unterschätzt.
Effektives Rammen von Ortbetonpfählen im Zusammenhang mit der Erschütterungswirkung/Effective Pile Driving and the Coherence with Vibration Emissions
Authors: Kopf F. , Söllhuber L. , Garbers T.
Published: March 2021

Es wird mithilfe einer messtechnisch empirischen Methode nachgewiesen, dass es bei der Variation der Geräte- und Prozessparameter beim Rammen von Pfählen einen prinzipiellen bodenmechanischen Zusammenhang zwischen der Rammeffektivität und den entstehenden Erschütterungen der Umgebung gibt. Dieser Zusammenhang wurde anlässlich einer Untersuchung zur Schaffung von Grundlagen für Erschütterungsprognosen für Ortbeton-Rammpfähle sowie der Beantwortung der Frage, ob sich durch Beschränkung der Fallhöhe des Rammbären eine sinnvolle Reduktion der Erschütterungen erzielen lässt, erkannt. Bei der messtechnischen Untersuchung der Erschütterungsausbreitung beim Rammen von Ortbetonpfählen mit verschiedenen Rammbären und mit unterschiedlichen Fallhöhen kann gezeigt werden, dass für effektives Rammen eine untergrundabhängige, minimale Rammenergie überschritten werden muss und dass sich diese Gesetzmäßigkeit in der Erschütterungsausbreitung in der Umgebung widerspiegelt. Dieser Zusammenhang ist dermaßen prägnant und reproduzierbar, dass sich mithilfe der empirisch hergeleiteten Diagramme die maximalen Erschütterungen in Abhängigkeit der Bodensteifigkeit abschätzen lassen.
Prüfkonzepte für Bewehrungsmaterialien mit zeitabhängigen Widerständen/Test concepts for reinforcement materials with time dependent resistances
Authors: Weber A.
Published: March 2021

Neuartige Bewehrungsmaterialien aus Glasfaser- oder Carbonfaserverbundkunststoff zeigen zum Teil deutliche Unterschiede zwischen Kurzzeit- und Langzeitwerten, insbesondere in Hinblick auf die Zugfestigkeit und den Verbund. Dieser Aufsatz zeigt verschiedene Wege auf, mit denen charakteristische Werte für diese Eigenschaften für den Bemessungszeitraum vorhergesagt werden können. Berücksichtigt werden dabei das semiprobabilistische Sicherheitskonzept der aktuellen und kommenden Normenfamilie sowie langjährige Erfahrungen mit den deutschen und ausländischen Zulassungsbehörden.

El objetivo de este documento es presentar una aproximación al concepto de investigación, definida fundamentalmente como un “conjunto de procesos sistemáticos, críticos y empíricos que se aplican al estudio de un fenómeno o problema, con el resultado u objetivo de ampliar su conocimiento” (Hernández & Mendoza, 2018), es decir que partiendo de una problemática podemos encontrar una solución a ella, bajo un estudio aproximado al fenómeno, desde diferentes modelos epistémicos y hacer un recorrido por los métodos de investigación de cada modelo, como elementos integrales de la vida del ser humano y que lo lleva a cuestionarse constantemente. Con esto se busca una explicación o solución a los fenómenos y problemas que suceden cotidianamente, intentando mejorar el entorno circundante, el estilo, ritmo y calidad de vida del ser humano a partir de horizontes conceptuales claros,  que contribuyan de forma holística e integral  en la construcción de un mejor y próspero futuro. Logrando así, ampliar las fronteras del  conocimiento con procesos metódicos y análiticos cada vez más articulados y razonables, con los objetivos aplicados a diversos estudios de múltiples eventos en los variados campos del saber, lo cual se retoma desde la postura de varios autores dando validez y consistencia intelectual a los planteamientos descritos.
