Progression of Hamate Hook Stress Reactions in Elite Baseball Players
Authors: Sochacki Kyle R. , Liberman Shari R. , Mehlhoff Thomas L. , Jones Jaclyn M. , Lintner David M. , McCulloch Patrick C.
Published: May 2020

Background:

Hamate hook fractures can occur as a result of repetitive contact with the knob of the bat used in the sport of baseball. Hamate hook excision has resulted in excellent outcomes and return to sport (RTS) in elite baseball players. The ideal treatment for hamate stress response before the development of a fracture line is unknown.

Purpose:

To report the outcomes of elite baseball players with hamate bone edema.

Study Design:

Case series; Level of evidence, 4.

Methods:

We reviewed the medical records of all elite baseball players with hamate bone edema consistent with a stress response at 2 institutions. Players were eligible for inclusion if they played collegiate or professional baseball at the time of initial injury, had magnetic resonance imaging (MRI) showing hamate bone edema, and had no radiographic evidence of acute fracture lines at initial presentation.

Results:

A total of 4 players with a mean age of 22.8 years were included. All injuries occurred in the nondominant hand. All athletes had normal initial wrist radiographs and MRI showing hamate edema but no fracture line. Patients returned to play as tolerated and developed an acute injury at an average of 25.8 days (range, 10-56 days) from the initial presentation. Repeat radiographs demonstrated acute hamate hook fractures in all 4 (100%) athletes. All 4 athletes underwent hamate hook excision. There were no postoperative complications. All athletes returned to sport at their previous level of competition at a mean of 5.3 weeks (range, 3.6-7.3 weeks).

Conclusion:

There is a high rate of hamate bone edema progression to acute hamate hook fracture in elite baseball players, with 100% RTS at preinjury level after hamate hook excision. We therefore recommend against prolonged rest. Continuation of play with hamate bone edema followed by hamate hook excision for acute fracture limits the time missed and obtains a faster RTS in elite baseball players.

Geographic Dispersion of Economic Shocks: Evidence from the Fracking Revolution: Reply
Authors: Feyrer James , Mansur Erin , Sacerdote Bruce
Published: May 2020

Measuring the geographic spillovers from an economic shock remains a challenging econometric problem. In Feyrer, Mansur, and Sacerdote (2017) we study the propagation of positive shocks from the recent boom in oil and gas production in the United States. We regress changes in income per capita on new energy production per capita within increasingly larger geographic circles. James and Smith (2020) proposes instead a single regression of county income per capita on energy production from successively larger donuts around the county. This method controls for production outside of the circle of interest and is likely the appropriate estimation method for estimating the impact of within-county production. Their results suggest that FMS overestimates the impact of new production. We show that we can incorporate similar controls using our basic estimation method and that (unlike James and Smith) these controls do not significantly change our results. To explore these differences, we perform simulation exercises which show that the James-Smith estimation method is biased downward with the heterogeneous population distributions across counties that we observe in the data.

Application of monoexponential, biexponential, and stretched-exponential models of diffusion-weighted magnetic resonance imaging in the differential diagnosis of metastases and myeloma in the spine-Univariate and multivariate analysis of related parameters
Authors: Xing Xiaoying , Zhang Jiahui , Chen Yongye , Zhao Qiang , Lang Ning , Yuan Huishu
Published: May 2020

Objective:

To explore the value of related parameters in monoexponential, biexponential, and stretched-exponential models of diffusion-weighted imaging (DWI) in differentiating metastases and myeloma in the spine.

Methods:

53 metastases and 16 myeloma patients underwent MRI with 10 b-values (0–1500 s/mm2). Parameters of apparent diffusion coefficient (ADC), true diffusion coefficient (D), pseudo-diffusion coefficient (D*), perfusion fraction (f), the distribution diffusion coefficient (DDC), and intravoxel water diffusion heterogeneity (α) from DWI were calculated. The independent sample t test and the Mann–Whiney U test were used to compare the statistical difference of the parameter values between the two. Receiver operating characteristics (ROC) curve analysis was used to identify the diagnostic efficacy. Then substituted each parameter into the decision tree model and logistic regression model, identified meaningful parameters, and evaluated their joint diagnostic performance.

Results:

The ADC, D, and α values of metastases were higher than those of myeloma, whereas the D* value was lower than that of myeloma, and the difference was significant (p < 0.05); the area under the ROC curve for the above parameters was 0.661, 0.710, 0.781, and 0.743, respectively. There was no significant difference in the f and DDC values (p > 0.05). D and α were found to conform to the decision tree model, and the accuracy of model diagnosis was 84.1%. ADC and α were found to conform to the logistic regression model, and the accuracy was 87.0%.

Conclusion:

The 3 models of DWI have certain values indifferentiating metastases and myeloma in spine, and the diagnostic performance of ADC, D, α and D*was better. Combining ADC with α may markedly aid in the differential diagnosis of the two.

Advances in knowledge:

Monoexponential, biexponential, and stretched-exponential models can offer additional information in the differential diagnosis of metastases and myeloma in the spine. Decision tree model and logistic regression model are effective methods to help further distinguish the two.
Focal nodular marrow hyperplasia: Imaging features of 53 cases
Authors: Rajakulasingam Ramanan , Saifuddin Asif
Published: May 2020

Objective:

To describe the characteristic imaging features of focal nodular marrow hyperplasia (FNMH).

Methods and materials:

Retrospective review of all patients with a diagnosis of FNMH between January 2007 and September 2019.

Results:

The study included 53 patients, 7 males and 46 females with a mean age of 58 years (range 12–95 years). All had MRI with conventional spin echo sequences showing a poorly defined round/oval lesion with mild T  1W iso/hyperintensity compared to skeletal muscle, low T  2W turbo spin echo (TSE) signal intensity (SI) compared to marrow fat and variable SI on STIR, but never associated with reactive marrow oedema. All 53 patients had follow-up MRI, with all lesions remaining stable or partially resolving. In-phase (IP) and out-of-phase (OP) chemical shift imaging (CSI) was obtained in 31 of these, with 28 (90.3%) showing >20% SI drop on the OP sequence, while 3 (9.7%) demonstrated <20% SI drop. CT was available in 26 cases, 17 (65.4%) showing mild medullary sclerosis. Single-photon emission computed tomography CT (SPECT-CT) was available in four cases and Flourodeoxyglucose positron emission tomography CT (FDG PET-CT) in 2, all showing increased uptake. Focal uptake was also seen in three of eight patients who had undergone whole body bone scintigraphy. Only one lesion was biopsied, confirming FNMH.

Conclusion:

The imaging appearances of FNMH have been described on various modalities, particularly MRI with emphasis on the role of IP and OP CSI typically demonstrating >20% SI reduction. FNMH should be recognised and treated as a 'do not touch' lesion which does not require biopsy or prolonged follow-up.

Advances in knowledge:

We describe and clarify the imaging characteristics of FNMH on MRI, including CSI, CT and various nuclear medicine modalities. An imaging algorithm is suggested for allowing a non-invasive diagnosis.
New Algorithms for Solving Zero-Sum Stochastic Games
Authors: Oliu-Barton Miquel
Published: May 2020

Zero-sum stochastic games, henceforth stochastic games, are a classical model in game theory in which two opponents interact and the environment changes in response to the players’ behavior. The central solution concepts for these games are the discounted values and the value, which represent what playing the game is worth to the players for different levels of impatience. In the present manuscript, we provide algorithms for computing exact expressions for the discounted values and for the value, which are polynomial in the number of pure stationary strategies of the players. This result considerably improves all the existing algorithms.
Grassroots Resistance to Digital Platforms and Relational Business Model Design to Overcome It: A Conceptual Framework
Authors: Ricart Joan Enric , Snihur Yuliya , Carrasco-Farré Carlos , Berrone Pascual
Published: May 2020

Although extant research has studied incumbent resistance to digital platforms, it provides little understanding about when grassroots collective action by other ecosystem stakeholders against the digital platform is likely. In this paper, we identify the scope conditions detailing when local stakeholders can initiate grassroots collective action against the digital platform, a unique context characterized by fast growth, distributed innovation, role flexibility, and direct local connectivity, and propose viable solutions. Our conceptual framework suggests that grassroots collective action against the digital platform is most likely when the digital platform operates with localized scarce assets or localized precarious labor and when actors express their grievances through formalized channels. We combine business model design and stakeholder management perspectives to develop design-based solutions that involve a multisided business model structure, an inclusive stakeholder value proposition, and an ecosystem-centered governance. We call the combination of such design efforts relational business model design. To the incipient theory of digital platforms, we contribute a stakeholder-centered view of platform business models operating within local ecosystems, bridging research on collective action and stakeholder management with strategic management of platforms.

Use of a closed-system drug transfer device reduces contamination with doxorubicin during bolus injection
Authors: Marler-Hausen Tom , Holt Chris , Headley Christine , Sessink Paul
Published: May 2020

Background:

Administration of doxorubicin via bolus injection may result in environmental contamination and a risk of nurses becoming exposed. Small spills are frequently observed by nurses when syringes are connected to, and disconnected from, infusion lines.

Aims:

The effect of a closed-system drug transfer device (CSTD) on the release of doxorubicin was studied during administration via bolus injections.

Methods:

10 administrations with the currently used technique and 10 administrations using the CSTD were compared by analysis of doxorubicin contamination on gauze pads, tissues and gloves.

Findings:

Using the current technique, contamination was found during nine administrations, which was mainly on the gauze pads and, to a lesser extent, on the tissues and gloves, indicating release of doxorubicin during administration. With use of the CSTD, contamination was found only on one pair of gloves.

Conclusion:

Use of a CSTD significantly decreased the number of spills and level of contamination compared with the currently used technique and, consequently, the use of such devices offers a safer working environment for nurses.

Authors: Burns Victoria , Misra Vivek , Paton Nina
Published: May 2020

The Christie NHS Foundation Trust is a leader in adapting patient care in response to treatment advances and new patient-centred care/efficiency initiatives. Due to extended waiting times in cancer clinics, The Christie developed an at-home treatment service to help reduce the pressure on clinics and improve patient experience. This article provides a detailed examination of the requirements necessary to successfully develop a home service for the delivery of systemic anticancer treatment. The authors discuss the criteria used to identify suitable at-home treatments, as well as necessary resources and equipment. The success of the Christie at Home service was examined using a patient survey to assess the standard of this care. Details are given regarding the challenges of implementing a homecare service and potential future challenges. As an example, systemic treatment with eribulin as a ‘Christie at Home’ therapy demonstrates the practicalities of introduction of new therapies in a homecare service.
Generation of above-terawatt 1.5-cycle visible pulses at 1  kHz by post-compression in a hollow fiber
Authors: Nagy Tamas , Kretschmar Martin , Vrakking Marc J. J. , Rouzée Arnaud
Published: May 2020

We report on the generation of 6.1 mJ, 3.8 fs pulses by the compression of a kilohertz Ti:sapphire laser in a large-aperture long hollow fiber. In order to find optimal conditions for spectral broadening at high pulse energies, we explore different parameter ranges where ionization or the Kerr effect dominates. After identifying the optimum parameter settings, large spectral broadening at high waveguide transmission is obtained. The intense 1.5-cycle pulses are used for high-harmonic generation in argon and neon.
‘Art is different’: Material practice, learning and co-making at The Social Studio
Authors: McQuilten Grace , Spiers Amy
Published: May 2020

This article examines the relationship between traditional and creative research methods through the case study of The Social Studio (TSS), an art-based social enterprise in Melbourne, Australia. TSS aims to address systemic barriers to employment and education for people from refugee and migrant backgrounds through training and work experience in fashion and textiles. Specifically, the article reflects on the embodied, co-making learning space and model of TSS which addresses some of the barriers faced by migrant and refugee students in accessing formal education. Our research brings together traditional research methods, such as interviews and observation, as well as a creative workshop where both research subjects and researchers were taught a weaving activity. The article reflects critically on the limitations of traditional research methods, the challenges of researching in creative community contexts and also the need to document and analyse how material and embodied experiences impact on social and community development.
Kōmako Quilters’ informal learning and the collective zone of proximal development: The ‘5x5 quilt’ project
Authors: Warner Linda Claire , Seitamaa-Hakkarainen Pirita , Hakkarainen Kai
Published: May 2020

This article discusses the informal learning processes of a quilting community, located in Aotearoa New Zealand, as participants engage in a collaborative textile project. Few studies have investigated everyday quilters’ collective learning processes, even though communal quiltmaking has been undertaken over the centuries. The concept of zone of proximal development (zpd) is extended as a ‘collective zone of proximal development’ where people are doing something together. This ethnographic study views quiltmaking as a sociocultural activity, and emphasizes the situated nature of knowing within a community-based setting. Research methods reveal the explicit and tacit dimensions of the quilters’ meaning making. During the fieldwork, flexibility and reflexivity are required to overcome ethical issues as they arise. The guided participation is revealed through the quilters’ interactions as they participated in their collaborative activity. Learning sequences present episodic details of the way these interactions are constructed and developed. The quilters actively seek to increase opportunities for learning and for sharing skills and knowledge through participation partnerships involving multi-way collaborations.

FONTES DO DIREITO COMO EXPRESSÕES LINGUÍSTICAS DE NORMAS JURÍDICAS E SUA HIERARQUIA: UMA VISÃO RETÓRICA
Authors: Adeodato João Maurício
Published: May 2020

Este trabalho tem por objetivo mostrar que as chamadas fontes do direito constituem significantes, com função de dar início ao processo de decisão de conflitos, para o qual se dirige a dogmática prática, e de conhecimento, para o qual se dirigem a filosofia, a teoria geral e a dogmática jurídica. A metodologia é a retórica indutiva (epagogé), dentro da história das ideias e da análise dos conceitos, e afasta-se de qualquer ontologia. Após expor o debate em torno da teoria das fontes, ressaltando as controvérsias sobre sua hierarquia, o texto mostra que ela forneceu um dos marcos importantes para o surgimento de duas ideias conexas e de grande importância: a origem do direito e a noção de indivíduo. Essa visão histórica da retórica pragmática conclui que o conceito de sujeito representa uma reação do indivíduo diante dos constrangimentos impostos pelo direito positivo, uma ordem que resiste a suas individualidades.
TERRITORIO Y DERECHO EN CARL SCHMITT: ALGUNAS REFLEXIONES
Authors: Miguel Carlos Ruiz
Published: May 2020

La relación del territorio con el Derecho puede ser vista simplemente como una cuestión del “ámbito de vigencia” de las normas. Pero la importancia del territorio va mucho más allá de la delimitación del ámbito de vigencia del Derecho. La relación del territorio con el Derecho, lejos de ser una cuestión sobre el “efecto” o las “consecuencias” del Derecho es una cuestión sobre el “origen” o génesis del Derecho. En este trabajo se argumentará que Kelsen realizó aportaciones sobre la cuestión de gran interés pero que contradecían su teoría normativista (I). Será, sin embargo, Schmitt quien desarrolle una teoría coherente sobre la relación del territorio con el Derecho a partir sobre todo de las ideas de “gran espacio” primero y “nomos” después (II). Ello nos llevará a presentar lo que consideramos un interesante punto de convergencia entre Kelsen y Schmitt (III). Después veremos cómo Schmitt desarrolla su teoría del nomos en sus últimos trabajos donde algunas de sus conclusiones parecen relativizar su propia teoría (IV). Finalmente, intentaremos argumentar que las ideas de Schmitt nos ayudan a comprender las transformaciones transnacionales del Derecho contemporáneo (V).
EL DERECHO FUNDAMENTAL A UNA BUENA ADMINISTRACIÓN: SU EXPRESIÓN A TRAVÉS DE LA REPARACIÓN DEL DAÃ‘O CAUSADO POR AGENTES Y FUNCIONARIOS. REALIDADES Y CONQUISTAS EN IBEROAMÉRICA
Authors: Ruiz Ana Celia Rivery
Published: May 2020

La Carta de los Derechos Fundamentales de la Unión Europea abre una nueva era para los derechos a partir de que este documento no sólo protegió los ya existentes, sino que consagró aquellos que habían sido definidos por la doctrina como derechos reaccionales e instrumentales y cuya naturaleza y desarrollo ha sido fundamentalmente jurisprudencial. Entre esos derechos, en su artículo 41 se consagra el derecho a una buena administración, el que a su vez está integrado por otros derechos, dentro de los cuales, en el apartado 3, está contenido el derecho de toda persona a la reparación de los daños causados por instituciones o agentes en el ejercicio de sus funciones. Tan importante conquista también atravesó océanos y unos años más tarde, en el 2013, Iberoamérica, acogía una carta donde la buena administración no era un derecho solamente, sino la finalidad de la Carta en sí, - la Carta Iberoamericana de los Derechos y Deberes del Ciudadano en relación con la Administración Pública- demostrando que, en su relación con la administración, ahora los ciudadanos ya no son sujetos inertes, simples receptores de bienes y servicios públicos; son protagonistas principales de los asuntos de interés general y disponen de una serie de derechos que promueva la dignidad humana y el respeto a la pluralidad cultural.
Sourgrass control in response to the association of 2,4-d to ACCase inhibitor herbicides
Authors: Gomes Hugo Leonardo Lima , Sambatti Vinícius Cesar , Dalazen Giliardi
Published: May 2020

ACCase inhibitor herbicides are widely used to control poaceae such as sourgrass (Digitaria insularis). However, these herbicides are selective for eudicots, which requires the use of broadleaf herbicides in areas with broadleaf and narrow leaf weeds. The objective of this study was to evaluate the effect of the association ACCase inhibitors and 2,4-D for the control of sourgrass. Two experiments were carried out under greenhouse conditions. The first experiment evaluated the effect of associating 2,4-D and graminicides to control of sourgrass, using dose-response curves for the herbicides clethodim, quizalofop-P-tefuril and clethodim + quizalofop-P-tefuril. In the second experiment, due to the results of the first one, the necessary period between the application of 2,4-D and the graminicides was evaluated in order to avoid antagonism in sourgrass. The results show that the herbicide clethodim, at the recommended dose, has its efficiency reduced in about 8% when applied in association with 2,4-D. As for the herbicide quizalofop-P-tefuril, this effect was higher, causing a reduction of 39% in control. However, the association of 2,4-D to the mixture of clethodim + quizalofop-P-tefuril did not result in antagonism. It takes nine and 12 days between the application of 2,4-D and the graminicides clethodim and quizalofop-P-tefuril, respectively, for there to be no antagonism.

Published: May 2020

This study aimed to determine the mechanical properties of fluoride-releasing dental materials after an accelerated fluoride recharge/discharge procedure. Two fluoride-releasing glass ionomer types of cement (Ketac Molar Easymix and IonoStar Molar), a resin-modified glass ionomer (Photac Fil Quick Aplicap), and two compomers (Compoglass F and Glasiosite) were used in this study. A total of 30 rectangular specimens and 30 disk specimens of each material were prepared and placed in distilled/deionized water (n = 5). The amount of fluoride released was analyzed from the materials for 7-day discharge, 1st recharge, 7-day discharge, 2nd recharge, and 7-day discharge, and 3rd recharge. The de/pre- and post-recharge ﬂuoride release were measured using an ion chromatography for 24 days. The flexural strength and microhardness of each group were evaluated. The microhardness of all restorative materials showed no significant change (p > 0.05) over the experimental period. The flexural strength properties of the restorative materials did not change within the time of the study. The study showed that the fluoride release/uptake causes no effect on the mechanical and physical properties of dental materials.

Published: May 2020

Yield and longevity of yellow passion fruit have been reduced by diseases such as the bacterial spot caused by Xanthomonas axonopodis pv. passiflorae. Genetic resistance has been confirmed as the most efficient and economical correct option to minimize this disease problem. Aiming at it, the objective of this research was to evaluate the incidence, severity and progression of the disease in 12 genotypes of sour passion fruit, in seedling stage in nursery greenhouse after inoculation of Xanthomonas axonopodis pv. passiflorae. The inoculation was performed with an isolate collected in the Pipiripau Rural Nucleus, Brasilia-DF, named UnB-1397 (1x106 CFU/mL), through induction of injuries. There were performed four assessments, with interval of 7 days except the first which was performed 11 days after inoculation. The incidence was estimated by the percentage of plants affected. To evaluate the severity, it was used the diagrammatic scale validated by Costa et al. (2018), with adaptations, using the measurement of the affected area by necrotic lesions on the leaf. All genotypes were susceptible to bacteriosis, 5 being considered moderately susceptible: F1 BRS Pérola do Cerrado x Rosa Intenso, Mar20#21, Mar20#15b, Mar20#24xMar20#40 and FB200PL4R2 x Mar20#2005, with a mean of severity ranging from 11 to 25% of injured area in leaves.

Published: May 2020

Melon (Cucumis melo L.) is a crop of great socioeconomic importance in regions with semiarid climate, as found in Northeast Brazil. In this region water deficit is a usual condition as well as the main reduction factor of plant productivity. Due to this phenomenon, irrigation techniques are used to make available the amount of water needed for plant production. Therefore, this research evaluated the physiology and fruit production changes of ‘Juazeiro’ Piel de sapo melon plants under different water replacement rates. ‘Juazeiro’ melon was grown under four reference evapotranspiration replacement rates (40, 60, 80 and 100% of ETo) distributed randomly in blocks with 5 replicates. The plants were cultivated in the field, in an experimental area located in the Brazilian Northeast region, under hot and dry semiarid climatic conditions, and during the growing cycle the ‘Juazeiro’ hybrid melon plants were evaluated for leaf area, biomass accumulation, gas exchange, photochemical efficiency of photosystem PSII and production of fruits per plant. Application of water replacement rates of 100% ETo leads to highest growth, net photosynthesis, and fruit yield of 'Juazeiro' melon. Water replacement at 80% ETo can be used for ‘Juazeiro” melon under semiarid climatic conditions, but with small losses in fruit yield. Water replacement below 80% ETo leads to drastic reductions in growth, gas exchanges, quantum efficiency of photosystem II and fruit yield, which impairs melon production in semi-arid climate environments.

Currently, the use of sodium bicarbonate (SB) as an ergogenic supplement has been linked to improved performance in several high-intensity and short time interval modalities because it is a natural buffer of the body fluids of the human body. This study aimed to evaluate the acute effect of SB supplementation on muscle strength endurance of resistance training practitioners. Crossover clinical trial, placebo-controlled (PL), and single-masked, included 10 trained adult men. The maximum repetition (1RM) and exhaustion tests with 80% 1RM were performed in the extensor chair and direct thread. In all sessions, the volunteers were verbally stimulated, the total maximum repetitions in the exercises and the blood lactate concentration were measured. SB was supplemented at a dose of 0.3 g/kg body mass. Statistical analysis was performed using SPSS version 25.0. The Shapiro–Wilk test was used to evaluate the normality of the data, and the Student’s t-test was used for independent and paired samples. The size of the Cohen’s effect was calculated, and the significance level was set at p<0.05. Comparing the supplements, no significant differences were found in all variables tested. However, when comparing pretest and posttest periods, significant differences were found between lactate concentrations, with considerably large effect sizes (> 1.00). SB supplementation by endurance training practitioners induces blood alkalosis, which reduces fatigue and possibly improves muscle strength endurance.

TRUST AND NETWORKS IN CLIMATE CHANGE ADAPTATION STRETEGIES: EXPERIENCE OF ACEH AND YOGYAKARTA IN EARTHQUAKE INTERVENTION
Authors: Absor Muhammad Ulil
Published: May 2020

AbstractIndonesia is one of the most disaster-prone countries where 1,782 disasters occurred between 2002 and 2007. The devastating impacts of the disasters, particularly the earthquake in Aceh and Yogyakarta, attracted public participation from various institutions.  The high participation of the institutions to some extent caused program ineffectiveness as many of those institutions have overlapping roles and fight over funding and beneficiaries. This paper will critically examine why networking is important in climate change adaptation based on the lessons learnt of disaster response in Aceh and Yogyakarta earthquake. This paper argues that the participation of stakeholders needs an effective networking. Networks are certainly becoming necessary in disaster intervention to avoid overlapping roles and conflict of interest between institutions involved in disaster response. Networks in community levels also become social capital that increases community’s resilience upon disaster. Keywords: disaster, intervention, social capital

AbstractIn the decentralization era, local governments are given more space to create a policy based on their people aspirations. Among others is the policy on poverty alleviation. Poverty which happens is not only absolute poverty but also cultural poverty and it is occurs in various regions in Indonesia. To fight the culture of poverty, the Government of Yogyakarta Special Region (DIY) published a Local Regulation No. 1 of 2014 about the Homeless and Beggars Handling. Overall this regulation contains about the homeless and beggars handling approach such as preventive, coercive, rehabilitative, repressive, and social re-integration. To examine this issue, the authors use SWOT analysis. The study results showed that the implementation strategy that can be done by the local government of DIY are conduct direct raids and coaching, optimizing ‘Desaku Menanti’ Program, reduce overlapping authority, providing labor-intensive jobs, synergy with the community and private sector in empowering sprawl in the activities of small and medium enterprises, enforcement of the rules in a way that is persuasive and humane, and provide an official aid channel for the donors. Although there are pros and cons in the implementation, this regulation basically has a noble purpose to make DIY free from homeless and beggars. Keywords: poverty culture, implementation strategy, local regulation of DIY, homeless and beggars

This paper discusses the study of plant waste thermocatalytic conversion. The dependence of the conversion of agricultural waste on the pyrolysis temperature, reaction time and feedstock particle size was determined. The optimal temperature of fast pyrolysis providing the highest yield of gaseous products (over 30 wt. %) for all types of waste plant biomass was found to be 700 ºC. This temperature allows the lowest tar content in gases to be obtained. Further, ZSM-5 synthetic zeolites modified with iron subgroup metals were studied in the conversion of volatile products obtained by the fast pyrolysis of agricultural waste. It was found that the use of zeolite-based catalysts in the upgrading of gaseous products leads to a decrease in tar content and the increase in the volume concentration of С1-С4 hydrocarbons, CO, CO2, and hydrogen in comparison with the non-catalytic process.
Eliminating Hydrogen Peroxide Volatiles after Lead White Conversion Treatment Via Sorption Agents
Authors: Raab Luise , Henniges Ute , Brückle Irene

Hydrogen peroxide (HP) residues that remain after the conversion of blackened lead white may cause unwanted paper discolouration and degradation. Four VOCs sorption materials were tested for their ability to eliminate HP gas evolving from the treated substrate. This was tested by measuring the change in HP concentration in aqueous solution and in an enclosed air space in the presence of MicroChamber® Interleaving Paper, Corrosion Intercept® film, Zorflex® activated carbon cloth (ACC) and iron sulphate-impregnated paper. Detection with the colour indicator Quantofix® test strips and a Dräger X-am® 5100 single gas detection device showed that ACC is by far most efficient in decreasing the HP concentration. ACC was also effective in preventing paper discolouration in test objects that had been HP-treated for lead white conversion and then were stored sandwiched between ACC. Although ACC may not eliminate all HP from the substrate, it can diminish its negative effects on the treated object and protect other objects in the vicinity.
„Da hatte ich einfach kein Interesse mehr daran.“ Analyse der Verläufe von Vereinsmitgliedschaftskarrieren jugendlicher Fußballer unter besonderer Berücksichtigung des Dropouts
Authors: Löbig Anna , Ehnold Peter , Schlesinger Torsten
Published: May 2020

Ausgehend von erhöhten Dropout-Quoten, welche mit negativen Konsequenzen für Verbände, Vereine oder Mitglieder einhergehen können, steht die Analyse typischer Vereinskarrieren jugendlicher Fußballer unter besonderer Berücksichtigung des Dropouts im Fokus des Beitrags. Ergänzend zu bisherigen, meist querschnittlich angelegten Studien wird dabei eine lebenslaufbezogene Perspektive eingenommen. Jugendliche Fußballer (n=15) aus verschiedenen Vereinen (n=4) wurden mit Hilfe des biografischen Mappings befragt. Dabei zeigen sich typische Verläufe in Abhängigkeit von der subjektiven Relevanz des Vereinswechsels (Vereins-Dropout) sowie des Fußball-Dropouts: „Vereins-Dropouts mit stabiler Fußballmitgliedschaft“ (Typ 1), „Plötzliche Fußball-Dropouts mit oder ohne vorherige Vereinswechsel“ (Typ 2), „Temporäre Fußball-Dropouts mit anschließendem Vereinswechsel“ (Typ 3) und „Instabile Fußballmitgliedschaftskarrieren“ (Typ 4). Diese Verlaufstypologien erweitern die bis-herige Befundlage um eine prozessuale/verlaufsbezogene Perspektive und eröffnen dadurch alternative Steuerungsoptionen im Umgang mit Dropouts.
Autoethnography for Extraterrestrials
Authors: Heywood Russell G.
Published: May 2020

The article explores a creative-artistic approach rooted in autoethnography, using satire and literary tropes from science fiction and fantasy. Edited excerpts from a completed PhD autoethno-satiric novel called The Doom of Clowns are used to illustrate the theoretical and ethical development of this narrative style. The advantages of employing science fiction and satire are demonstrated through the otherworldly narrative distance and ambiguity these genres allow.

The first natural history data is reported for the tortoise beetle, Cyrtonota serinus (Erichson, 1847) (Chrysomelidae: Cassidinae: Mesomphaliini). An Ipomoea sp. (Convolvulaceae) is recorded as the host plant. Larvae and adults feed on the leaves. Larvae retain an exuvio-fecal shield and are gregarious. Adults are sexually dimorphic and polymorphic in sizes and coloration.

En la Amazonia Peruana los caracoles dulceacuícolas de la familia Ampullariidae son conocidos como churos y originalmente han sido descritas para Perú alrededor de 20 especies. Aunque son muy usadas para alimentación, medicina tradicional y objeto de muchos estudios para su cultivo e industrialización, solamente es mencionada en la literatura la especie Pomacea maculata. Se llevó a cabo la identificación molecular sobre la base del marcador mitocondrial COI, de individuos de churos negros (Pomacea) comercializados en los mercados de Iquitos, así como los usados en platos a la carta en la ciudad de Lima, contrastados con otros individuos de procedencia de su hábitat natural. Se encontró que estos especímenes expendidos corresponden a la especie Pomacea nobilis (Reeve, 1856). El análisis filogenético molecular mostró que P. nobilis es especie hermana de P. guyanensis, en el grupo de P. glauca, distantemente relacionada de P. maculata. Las distancias no corregidas encontradas entre ellas, para el marcador mitocondrial COI, fueron de 11.33% a 13.17%, mientras que con P. maculata fueron de 13.67% a 15.33%. Estos resultados demostraron la eficacia del código de barras de ADN para la identificación y autenticación de la especie, lo que le da un valor agregado para su eventual comercio de exportación.
