Published: April 2019

With the emergence of shared bicycles, people travel is more and more convenient. However, the smart bicycle lock with wireless transceiver system must have sufficient electric energy for normal work. In this paper, a ferrofluid-based planar vibration energy harvester is proposed to convert low-frequency vibration energy into electrical energy. The electromagnetic generator is designed and studied experimentally. The energy harvesting system is installed in the backseat and the front basket turning with the front fork, respectively. Experimental results indicate the collected energy is 0.010 J in the backseat and 0.020 J in the front basket for the maximal experiment distance of 1.16 km, respectively, which can meet the demand of the smart bicycle lock.
Günümüz Toplumlarında Anneliğin Değişen Biçimlerini Sosyal Medya Kullanıcıları Üzerinden Değerlendirmek

Published: April 2019

Geleneksel ve modern toplumlarda kadın ve erkeklerin çocuk sahibi olma arzuları; bireysel sorumlulukların artması,
işsizlik ve yoksulluk sınırında yaşayan kişilerin sayısındaki artış, anne-baba olmanın beraberinde getirdiği
yükümlülükler, hastalık-sağlık konusunda meydana gelen değişimlerden etkilenmektedir. Tıbbi ve teknolojik
gelişmelerin ön plana çıkması, bilgi-iletişim ağlarının kolay ve hızlı ulaşılabilirliği sağlaması, doğum kontrol
yöntemleri gibi birtakım tedbirlere başvurma imkanları, kadınların ve erkeklerin anne-baba olma düşüncesini yeniden
gözden geçirmesini beraberinde getirmiştir. Bununla birlikte günümüz toplumlarında mesleki birikimi artırmak, eğitim
imkânlarından yararlanmak, mobil hareketliliği gerektirecek iş kollarındaki istihdamın artması özellikle kadınların
anne olma düşüncesini ötelemelerine sebep olmuştur. Fakat son yıllarda sosyal medya kullanıcılarının artması ve
televizyon programları ile bilgi-iletişim teknolojilerinin sunduğu yazın dünyası kadınları anneliğe ve özellikle de
anneliğin değişen biçimlerine uyum sağlamaya davet etmektedir. Şöyle ki, sosyal medya ağlarından ınstagramda
oluşturulan bloglarda kadınlar, anne olmaya karar verdikleri andan itibaren anne adaylarının ne yemeleri ne içmeleri
gerektiği, hangi siteden alışveriş yapabileceklerine dair tavsiyeleri, bir taraftan kilo alırken diğer taraftan formlarını
korumak için nelere dikkat etmeleri gerektiği gibi bir dizi yapıp etmeleri kadınlarla paylaşmakta ve en çok beğeni alan,
en çok takip edilen listesi için adeta bir yarış içine girmektedirler. Bu durum kimi kadınlarda anneliğin arzulanan bir
duyguya dönüşmesini sağlarken kimi kadınlarda tam tersine kaçınılan bir duygu ve davranış biçimine dönüşmektedir.
Bu çalışma, özellikle günümüz toplumlarında kadınların annelik konusunda sosyal medya ağları üzerinden neleri takip
ettikleri, bu konuda yapılan paylaşımların ön plana çıkan yönleri, çocuk bakımı ve sorunları ile ilgili kaygı ve
problemlerin nasıl çözüleceği ve bununla ilgili uzman dışı kişilerin görüşlerine nasıl başvurdukları, sosyal medya
ağlarından yaptıkları paylaşımlarla çocuk hakları konusunda doğabilecek sorunları nasıl görmezden geldikleri söylem
analizi yöntemiyle irdelenmeye çalışılmıştır. Bunun için en çok kullanılan sosyal medya ağlarından facebook ve
ınstagram kullanıcılarının anneliğe dair paylaşımları ile ilgili genel bir değerlendirme yapılmıştır. Söz konusu bilgiiletişim teknoloji ağları üzerinden hareketle annelik olgusunun kamusal alana hangi anlam ve pratiklerle taşındığı,
takip eden kişilerin bu paylaşımlara karşı nasıl bir yorumsal dil geliştirdikleri de analiz edilerek irdelenmeye
çalışılmıştır. Yapmış olduğumuz çalışmada, gündelik yaşam pratiklerini geniş kitlelere ulaştırabilen sosyal medyanın,
diğer alanlarda olduğu gibi annelik kimliğinin dönüşümüne de sebep olduğu gerçeğine ulaşmıştır. Bununla birlikte çocukları ile ilgili paylaşımların kimi zaman çocuk haklarına zarar verebilecek boyutlara ulaştığı da gözlemlenmiştir.
Model Komunikasi Interpersonal Orangtua terhadap Anak Autis

Published: April 2019

Communication has an important role in human life, since childhood, humans have communicated through the presence of parents. The role of parents greatly determines the process of developing communication in a child. But not all children are born in a normal state, including those who are blessed with a child with special needs such as autism. Even though every child has the potential in him, if he is not aware and cared for, it causes self-distrust in the child, a slow process of self-development, and some problems that are generally found in children with autistic disorders are in the social and communication aspects that are very lacking or slow . This paper focuses on discussing the model of interpersonal communication in developing the self potential of autistic disorder children. With document study methods that utilize various related research literature, as well as analytical techniques carried out by organizing and reducing data, then categorizing data, formulating to draw conclusions. The results of this paper indicate that many communication models must adapt to the characteristics of autistic disorders experienced by each child.

A falta e a distância da energia elétrica tradicional no meio rural e com a disponibilidade no mercado de modernos equipamentos como sistemas de captação e armazenamento de energia solar podem garantir ao produtor rural novas formas de manejo. A pesquisa foi conduzida na área experimental do Departamento de Engenharia Agrícola, na Universidade Federal Rural de Pernambuco, localizada em Recife-PE. Delimitou-se um piquete de 400 m2 com auxílio de varetas plásticas e fio eletroplástico, formando uma cerca de contenção, eletrificada com eletrificador solar fotovoltaico pulsante. Escolheram-se dois dias aleatórios entre os meses de julho e agosto, e mensurou-se do nascer ao pôr do sol, em intervalos de 30 minutos, a temperatura, umidade relativa do ar, voltagem, pulso, a intensidade de lux e a temperatura do painel do solar. Aplicou-se a análise estatística multivariada, por meio de dois métodos, Agrupamento (AA) e Fatorial (AF), o que permitiu relacionar e associar as variáveis analisadas, reduzindo-as em 2 componentes principais. Observou-se que a intensidade de lux é dependente da temperatura do ar, e a relação da umidade com a temperatura, é inversamente proporcional. Logo, o pulso está diretamente ligado com a voltagem produzida pelo equipamento, que por sua vez também se agrupam com a temperatura do painel. A análise fatorial explicou com as duas componentes principais 83,6 %. O uso de cercas elétricas alimentadas por energia fotovoltaica é viável na região em questão devido as variáveis ambientais contribuem para funcionalidade da cerca de forma satisfatória.

Lathyro asphodeloidis-Klaseetum lycopifoliae, a new plant association in the alliance Cynosurion cristati Tüxen, 1947 in Central Apennines
Authors: Ciaschetti Giampiero , Pirone Gianfranco 
Published: April 2019

This study presents a new plant association discovered in the Central Apennines and named Lathyroasphodeloidis-Klaseetumlycopifoliae. It consists of a semi-natural meadow characterized by the co-dominance of two rare taxa, Klasealycopifolia and Lathyruspannonicussubsp.asphodeloides, occurring in Italy in only a few localities in the Central and Northen Apennines. The association was discovered on the Altopiano delle Rocche high plateau in the province of L’Aquila (Abruzzo region, Italy).
Multivariate analysis of the relevés shows two floristic and ecological aspects, corresponding to two different subassociations: festucetosum circummediterraneae, with elements from the Festuco-Brometea class, growing in the outer portions of the plateau, and narcissetosum poëtici, corresponding to the most typical aspect and occupying the central part of the plateau, differentiated by meso-hygrophilous species of the Molinietalia and Trifolio-Hordeetalia orders.
The plant association has great natural value, due to the presence of several rare plant species, and cultural importance in association with the traditional “Narcissus Fest” held each year in May.
The influence of collaboration-oriented organisational capabilities on supply chain competence among small and medium enterprises
Authors: Pooe David , Munyanyi Watson 
Published: April 2019

Orientation: In the contemporary business environment, there is need for firms to strategically interact with partners beyond boundaries, and by collaborating these firms can access resource and technologies beyond their limits.Research purpose: The aim of this study was to investigate the influence of collaboration-oriented organisational capabilities (COOC) on supply chain competence among small and medium enterprises (SMEs) in Zimbabwe.Motivation for the study: Small and medium enterprises in Zimbabwe have experienced limited growth, primarily because of their failure to nurture and steer their competencies. The literature suggests that there is value in synchronised cooperative and competitive interactions between firms as such interactions incentivise the pursuit of shared interests.Research design, approach and method: Through a cross-sectional survey, data were collected from 388 SMEs in Zimbabwe, and structural equation modelling was used to analyse the data.Main findings: The study specifically found that there is a positive and significant relationship between collaboration-oriented capabilities and supply chain competence.Practical/managerial implications: The results of this study demonstrate the critical role of organisational capabilities in achieving supply chain competence. The study proves that collaborative capabilities are central to the supply chain success of SMEs, with the possibility of influencing also the firm’s sustainable competitive advantage in line with the dynamic capabilities theory.Contribution/value-add: This study sheds light on the possibility of enhancing the overall supply chain competence of SMEs by establishing and empirically testing the relationships between COOC and supply chain competence.
BVOC–aerosol–climate feedbacks investigated using NorESM

Abstract. Both higher temperatures and increased CO2 concentrations are
(separately) expected to increase the emissions of biogenic volatile organic
compounds (BVOCs). This has been proposed to initiate negative climate
feedback mechanisms through increased formation of secondary organic aerosol
(SOA). More SOA can make the clouds more reflective, which can provide a
cooling. Furthermore, the increase in SOA formation has also been proposed to
lead to increased aerosol scattering, resulting in an increase in diffuse
radiation. This could boost gross primary production (GPP) and further
increase BVOC emissions. In this study, we have used the Norwegian Earth
System Model (NorESM) to investigate both these feedback mechanisms. Three
sets of experiments were set up to quantify the feedback with respect to (1) doubling
the CO2, (2) increasing temperatures corresponding to a doubling of
CO2 and (3) the combined effect of both doubling CO2 and a
warmer climate. For each of these experiments, we ran two simulations, with
identical setups, except for the BVOC emissions. One simulation was run with
interactive BVOC emissions, allowing the BVOC emissions to respond to changes
in CO2 and/or climate. In the other simulation, the BVOC emissions
were fixed at present-day conditions, essentially turning the feedback off.
The comparison of these two simulations enables us to investigate each step
along the feedback as well as estimate their overall relevance for the future
climate. We find that the BVOC feedback can have a significant impact on the climate.
The annual global BVOC emissions are up to 63 % higher when the feedback
is turned on compared to when the feedback is turned off, with the largest
response when both CO2 and climate are changed. The higher BVOC
levels lead to the formation of more SOA mass (max 53 %) and result in
more particles through increased new particle formation as well as larger
particles through increased condensation. The corresponding changes in the
cloud properties lead to a −0.43 W m−2 stronger net cloud forcing.
This effect becomes about 50 % stronger when the model is run with
reduced anthropogenic aerosol emissions, indicating that the feedback will
become even more important as we decrease aerosol and precursor emissions. We
do not find a boost in GPP due to increased aerosol scattering on a global
scale. Instead, the fate of the GPP seems to be controlled by the BVOC effects
on the clouds. However, the higher aerosol scattering associated with the
higher BVOC emissions is found to also contribute with a potentially
important enhanced negative direct forcing (−0.06 W m−2). The global
total aerosol forcing associated with the feedback is −0.49 W m−2,
indicating that it has the potential to offset about 13 % of the forcing
associated with a doubling of CO2.

ImportanceCorrection of tricuspid regurgitation using tricuspid transcatheter edge-to-edge repair (T-TEER) in addition to guideline-directed optimized medical therapy (OMT) may improve clinical outcomes.ObjectiveTo evaluate the efficacy of T-TEER + OMT vs OMT alone in patients with severe, symptomatic tricuspid regurgitation.Design, Setting, and ParticipantsInvestigator-initiated, prospective, randomized (1:1) trial evaluating T-TEER + OMT vs OMT alone in adult patients with severe, symptomatic tricuspid regurgitation. The trial was conducted at 24 centers in France and Belgium (March 2021 to March 2023; latest follow-up in April 2024).InterventionPatients were randomized to T-TEER + OMT or OMT alone.Main Outcomes and MeasuresThe primary outcome was a composite clinical end point at 1 year comprising change in New York Heart Association class, change in patient global assessment, or occurrence of major cardiovascular events. Tricuspid regurgitation severity was the first of 6 secondary outcomes analyzed in a hierarchical closed-testing procedure, including Kansas City Cardiomyopathy Questionnaire (KCCQ) score, patient global assessment, and a composite outcome of all-cause death, tricuspid valve surgery, KCCQ score improvement, or time to hospitalization for heart failure.ResultsOf 300 enrolled patients (mean age, 78 [SD, 6] years, 63.7% women), 152 were allocated to T-TEER + OMT and 148 to OMT alone. At 1 year, 109 patients (74.1%) in the T-TEER + OMT group had an improved composite score compared with 58 patients (40.6%) in the OMT-alone group. Massive or torrential tricuspid regurgitation was found in 6.8% of patients in the T-TEER + OMT group and in 53.5% of those in the OMT-alone group (P &amp;lt; .001). Mean overall KCCQ summary score at 1 year was 69.9 (SD, 25.5) for the T-TEER + OMT group and 55.4 (SD, 28.8) for the OMT-alone group (P &amp;lt; .001). The win ratio for the composite secondary outcome was 2.06 (95% CI, 1.38-3.08) (P &amp;lt; .001).Conclusions and RelevanceT-TEER reduces tricuspid regurgitation severity and improves a composite score driven by improved patient-reported outcome measures in patients with severe, symptomatic tricuspid regurgitation.Trial RegistrationClinicalTrials.gov Identifier: NCT04646811

ImportanceMerkel cell carcinoma (MCC) is a rare but aggressive skin cancer. Quantifying the contribution of major potentially modifiable risk factors to the burden of MCC may inform prevention efforts.ObjectiveTo estimate the population attributable fraction of MCC cases in the US that were attributable to major immunosuppressing conditions (eg, HIV, solid organ transplant, chronic lymphocytic leukemia [CLL]), ambient UV radiation [UVR] exposure, and Merkel cell polyomavirus [MCPyV]).Design, Setting, and ParticipantsThis epidemiological assessment combined data from population-based registries and case series and included cases of MCC that were diagnosed from January 2001 to December 2019 diagnosed in people with HIV, solid organ transplant recipients, and patients with CLL who were identified through population-based cancer registries and linkages with HIV and transplant registries. UVR-based on cloud-adjusted daily ambient UVR irradiance was merged with cancer registry data on the county of residence at diagnosis. Studies reporting the prevalence of MCPyV in MCC specimens collected in the US were combined via a meta-analysis.ExposuresHIV, solid organ transplant, CLL, UVR, and MCPyV.Main Outcomes and MeasuresPopulation attributable fraction of MCC cases attributable to major risk factors.ResultsA total of 38 020 MCCs were diagnosed in the US among xx patients (14 325 [38%] female individuals; 1586 [4%] Hispanic, 561 [1%] non-Hispanic Black, and 35 171 [93%] non-Hispanic White individuals). Compared with the general US population, MCC incidence was elevated among people with HIV (standardized incidence ratio [SIR], 2.78), organ transplant recipients (SIR, 13.1), and patients with CLL (SIR, 5.75). Due to the rarity of these conditions, only 0.2% (95% CI, 0.1%-0.3%) of MCC cases were attributable to HIV, 1.5% (95% CI, 1.4%-1.7%) to solid organ transplant, and 0.8% (95% CI, 0.5%-1.3%) to CLL. Compared with individuals of racial and ethnic minority groups, MCC incidence was elevated among non-Hispanic White individuals at lower and higher ambient UVR exposure levels (incidence rate ratios: 4.05 and 4.91, respectively, for MCC on the head and neck). Overall, 65.1% (95% CI, 63.6%-66.7%) of MCCs were attributable to UVR. Based on a meta-analysis of 19 case series, 63.8% (95% CI, 54.5%-70.9%) of MCCs were attributable to MCPyV. Studies were identified from a MEDLINE search performed on October 12, 2023.Conclusions and RelevanceThe results of this study suggest that most MCC cases in the US were attributable to ambient UVR exposure or MCPyV, with a small fraction due to immunosuppressive conditions. Efforts to lower MCC incidence could focus on limiting UVR exposure.
Staining Procedures
Authors: Dallas Steven D. , Harrington Amanda T. 
Published: November 2024

Abstract

This chapter presents two primary applications of the Gram stain in clinical microbiology. The first and most immediately impactful application is to detect and differentiate microorganisms including bacteria, yeast, fungi, and even some parasites directly from specimens. The second application is to confirm and describe bacterial growth from solid or liquid culture media as the first step in bacterial identification flowcharts. Bacteria stain is either Gram positive or Gram negative on the basis of differences in cell wall composition and architecture. The acridine orange fluorescent stain is an adjunct to or confirmatory test for the Gram stain, of use especially when direct specimen Gram stain results are inconclusive. The detection of leukocytes, predominantly neutrophils, in methylene blue‐stained fecal specimens assists in the diagnosis of infectious diarrhea. Dark‐field microscopy is used to demonstrate the presence of motile spirochetes of
Treponema pallidum
in lesions or aspirates in early‐stage syphilis prior to healing of lesions.
