Published: September 2019

Aims A number of methods have been described to remove a well-fixed humeral implant as part of revision shoulder arthroplasty. These include the use of cortical windows and humeral osteotomies. The router bit extraction technique uses a high-speed router bit to disrupt the bone-implant interface. The implant is then struck in a retrograde fashion with a square-tip impactor and mallet. The purpose of this study was to determine the characteristics and frequency of the different techniques needed for the removal of a well-fixed humeral stem in revision shoulder arthroplasty. Patients and Methods Between 2010 and 2018, 288 revision shoulder arthroplasty procedures requiring removal of a well-fixed humeral component were carried out at a tertiary referral centre by a single surgeon. The patient demographics, indications for surgery, and method of extraction were collected. Results Of the 288 revisions, 284 humeral stems (98.6%) were removed using the router bit extraction technique alone. Four humeral stems (1.39%) required an additional cortical window. Humeral osteotomy was not necessary in any procedure. Most of the humeral stems removed (78.8%) were cementless. Of the four humeral stems that required a cortical window, three involved removal of a hemiarthroplasty. Two were cemented and two were cementless. Conclusion The router bit extraction technique removed a well-fixed humeral component in a very high proportion of patients (98.6%). This method allows surgeons to avoid more invasive approaches involving a cortical window or humeral osteotomy, and their associated complications.

Published: September 2019

Abstract
This systematic review examined 14 U.S. studies published since 2000 reporting prevalence estimates for intellectual disability (ID) or developmental disability (DD). Prevalence rates for children were between 11.0 and 13.4 per 1,000 for ID and between 45.8 and 69.9 per 1,000 for DD using data from 2010 or later. A 2015 Ohio study of adults yielded a prevalence estimate of 41.0 per 1,000 for DD. The only study of ID in adults and the only study incorporating DD Act definitions used the 1994/1995 NHIS-D yielding prevalence estimates for ID and/or DD of 38.2 per 1,000 for children birth to 5 years, 31.7 for children 6 to 18 years, and 7.9 per 1,000 for adults. Notable differences in prevalence estimates by age and operational definition have important implications for public policy and research. Serious surveillance gaps limit our understanding of service utilization rates, unmet needs, and health and other outcomes for adults with ID or DD.

Published: September 2019

O Software Bernese GNSS (BSW) é um conjunto de pacotes de processamento de observáveis GNSS (Global Navigation Satellite System) de alto desempenho, que proporciona estimativas com alta acurácia, e flexibilidade em suas aplicações. Uma destas funcionalidades é a automatização de scripts que realizam o Posicionamento por Ponto Preciso (PPP). O objetivo deste trabalho é analisar as potencialidades do PPP no BSW. Para alcançar esse propósito foram estimadas as coordenadas de 90 estações da RBMC (Rede Brasileira de Monitoramento Contínuo dos Sistemas GNSS) no BSW e no serviço IBGE-PPP online, referenciadas a atual realização do International GNSS Service, o IGS14, na época dos dados. As coordenadas estimadas foram comparadas com as coordenadas de referência das estações (SIRGAS2000, época 2000,40), de três formas distintas: 1. Referenciais e épocas incompatíveis; 2. Compatibilização apenas dos referenciais; e 3. Referenciais e épocas compatíveis. As acurácias das coordenadas reduziram no processo de compatibilização de referenciais. Como esperado, o fator predominante na alteração das coordenadas planimétricas se refere à sua evolução temporal. Ademais, as acurácias planimétricas e altimétricas apresentaram estatísticas descritivas similares ao nível do milímetro, evidenciando a potencialidade do BSW no PPP.

Published: September 2019

Dengue is the most common urban disease that is most prevalent in tropical areas. WHO 2009 stated that these diseases has grown a public health concern due to the risk of dengue infection that has increased dramatically between 50 and 100 million cases every year. This issue was very corresponded with landscape and environment changes. The objective of this paper is to discuss how landscape patterns in relation to dengue incidence. Open website; idengue were highly contributed in this study to locate the most risky area for dengue fever incidence at the township level. Geographic information system (GIS) was used to demonstrate the spatial patterns of all dengue cases in Johor Bahru and Geoprocessing was used to measure the boundary of risk according to the distribution of dengue outbreak. After that, to analyze the spatial landscape pattern, satellite images were used. Spatial descriptive analysis shows non-strata housing, open space, road, planned commercial, strata housing and drainage system network is the most prevalence land use activity for dengue incidence in Iskandar Region. The finding shows the common landscape composition that relates to dengue cases. In conclusion, the future development of land use should be considered on landscape pattern towards rapid urbanization.
Perception of Ultrasonic Vocalizations by Socially Housed and Isolated Mice
Authors: Screven Laurel A. , Dent Micheal L. 
Published: September 2019

AbstractIt is currently unclear whether mice use their ultrasonic vocalizations (USVs) for communication purposes. It is also unknown whether mice require previous experience with USVs to understand conspecifics. There is some evidence that experience changes the perception of juvenile USVs; however, it is unclear whether similar plasticity also occurs for adult USVs. To examine whether social exposure or deprivation throughout development leads to changes in USV perception, eleven female CBA/CaJ mice were trained to discriminate between 18 USVs of three different categories using operant conditioning procedures. Mice were group housed with four females or housed individually from weaning for the duration of the experiment. Socially housed and isolated mice differed in initial training times on pure tones, suggesting isolated mice had a more difficult time learning the task. Both groups completed USV discrimination conditions quicker at the end of the testing phases relative to the beginning. The overall discrimination of USVs did not differ between the two housing conditions, but a multidimensional scaling analysis revealed that socially experienced and isolated mice perceive some USVs differently, illustrated by differences in locations of USVs on the scaling maps from the two groups. Finally, a negative correlation was found between spectrotemporal similarity and percent discrimination, and analyses support the idea that mice may show categorical perception of at least two of the three USV categories. Thus, experience with USVs changes USV perception.

Merajalelanya korupsi menandai bahwa persoalan pendidikan karakter bangsa harus menjadi perhatian semua pihak, pemimpin bangsa, aparat penegak hukum, pendidik dan tokoh-tokoh agama, golongan dan lain sebagainya. Pembangunan karakter harus dibentuk. Studi ini dilakukan berangkat dari keprihatinan saya persoalan yang dihadapi bangsa Indonesia dalam hal pendidikan karakter, lalu menganalisis fakta-fakta yang ada, dan dari sana menawarkan berbagai alternatif penyelesaian. Dari hasil analisis dan pembahasan, didapatkan kesimpulan bahwa pembangunan karakter jika ingin efektif dan utuh mesti menyertakan tiga institusi, yaitu keluarga, sekolah dan masyarakat. Karena itu, langkah pertama yang harus dilakukan adalah menyambung kembali hubungan dan educational networks yang nyaris putus antara ketiga institusi pendidikan ini. Tanpa tiga institusi itu, program pendidikan karakter sekolah hanya menjadi wacana semata tidak akan berhasil karena tidak ada kesinambungan dan harmonisasi. The current state of corruption should encourage every citizens of the nation, all parties, the leaders of the nation, law enforcement officials, educators and religious leaders, to focus their attention to character building. Character development should be established as part of the national strategy to improve nationâ€™s life. The study begins from my concern about the backwardness of character education in Indonesia, and then from there I attempts to propose alternative solutions. The article concludes that to be successfull, character development should include the participation of three important institutions of social life: family, school and community. Therefore, the first stepÂ isÂ to reconnect the educational institutions with other institutions. Without the three institutions, the school character education program is only a discourse which will not succeed because there is no continuity and harmonization.
La contaminación del aire, un problema de todos
Authors: Medina Palacios Edna Katalina 
Published: September 2019

El estudio de carga de la enfermedad por factores ambientales que desarrolló la Organización Mundial de la Salud (OMS) en el año 2016 estimó que incidentes como accidentes cerebrovasculares, enfermedad pulmonar obstructiva crónica, asma en niños, cáncer de pulmón, enfermedad isquémica del corazón y enfermedades respiratorias de vías aéreas inferiores pueden ser atribuidos a la contaminación del aire (1). Esta carga depende de factores como la intensidad, la frecuencia y el tiempo de exposición a la contaminación.Estudios han indicado que la contaminación del aire, per se, no es un factor causal directo de los eventos antes descritos, pero sí es un factor asociado que, en combinación con otros determinantes como la desnutrición, las enfermedades de base o comorbilidades, la contaminación intradomiciliaria por tabaquismo pasivo, la falta de vacunación, las condiciones higiénicas deficientes o nulas y los factores ambientales como el clima, puede desencadenar su presencia.La problemática de contaminación del aire en Bogotá D.C. se debe, en su mayoría, a la presencia de material particulado, el cual es originado a partir de procesos de combustión y resuspensión provenientes de fuentes móviles y del mal estado de las vías (2). A esto se suma el transporte de partículas generadas por incendios forestales de impacto regional, que a su vez ocasionan episodios críticos de contaminación del aire como los que se vienen presentando en los últimos años y tienen impacto en la salud pública (Figura 1). Cabe anotar que este contaminante es el de principal estudio dada su capacidad de transporte de agentes de riesgo como virus, bacterias y algunos metales; además, tiene la habilidad de ingresar con mayor facilidad al cuerpo humano.

Authors: OLOWOLAJU Ezekiel Dare 
Published: September 2019

The effects of exogenous application of hydrogen peroxide on the secondary metabolites, enzyme activities and photosynthetic pigment accumulation of Vigna unguiculata was investigated. The hereby study was carried out under a screen house to minimize extraneous factors. The experiment was laid down in completely randomized design (CRD) with eight replicates. After two weeks of sowing when the seedlings become fully established, the sample pots were divided into two regimes. The first regimes were supplied daily with 500 mL of 0.1 mM of hydrogen peroxide and the second regime was watered daily with tap water. After fifth week of sowing, the leaves of Vigna unguiculata from each regime were randomly selected and harvested. Secondary metabolites, enzyme assay and photosynthetic pigment screening was carried out on the harvested leaves. The impact of hydrogen peroxide on the parameters studied was done using one way analysis of variance. Mean values were separated using Fisher’s LSD at p≤0.05. The results showed that hydrogen peroxide strongly increased the accumulation of secondary metabolites such as flavonoids, glycosides, saponins, carbohydrates and alkaloids. It also induced α-amylase and lipase activities than the control plants and promotes the accumulation and biosynthesis of chlorophylls and carotenoids. In conclusion, hydrogen peroxide could be used as potential molecule to improve some secondary metabolites (flavonoids, glycosides, saponins, carbohydrates and alkaloids), α-amylase and lipase activities and photosynthetic pigments.

Published: September 2019

Matured spores of four (4) species of maiden hair ferns namely, Adiantum capillus-veneris L., A. caudatum L., A. edgeworthii Hook. and A. incisum Forssk. were collected and grown in petri-dishes containing natural media formed by mixing dead wood of tree fern (Cyathea Sm.), sand and charcoal powder (2:1:1). The cultures in triplicates for each species were monitored every day from the stage of sowing to the chimera formation. After disintegration of gametophytes, juvenile sporophytes were shifted to pots and morphological characters were studied till the dehiscence of sporangia. Spore germination initiated between 4-6 days for A. capillus-veneris, 7-9 days in A. caudatum and A. incisum and 10-12 days in A. edgeworthii. Prothallia in all the Adiantum are autotrophic, Vittaria type, cordate-shaped, homosporous with antheridia developing earlier than archegonia and remain confined on the adaxial surface. The gametophytes showed considerable variation in their shapes, orientation of lobes, presence or absence of hairs and placement of sex organs on the prothallia. The gametophytic and sporophytic characters are correlated and used in structuring key to species. The study concludes that gametophytic characters also constitute a dependable criterion for assessing their systematics.
Türkiye’de pestisitlerin ruhsatlandırılmasının tarihsel değişimi ve gelişimi üzerine değerlendirmeler

Published: September 2019

Pestisit terimi herhangi zararlı bir organizmayı önlemek, uzaklaştırmak, öldürmek veya baskılamak için kullanılan doğal, organik veya sentetik kimyasal madde veya mikroorganizmaları ifade etmektedir. Pestisit terimi genellikle bitki koruma ürünü anlamında kullanılmakla birlikte aslında bu iki terim birbirinden farklı anlama sahiptir. Bitki koruma ürünleri bitkileri sağlıklı tutmak ve zararlı organizmalardan korumak amacıyla kullanılan pestisitlere karşılık gelmektedir. Bunlar insektisit, akarisit, nematisit, herbisit, fungisit, bitki büyüme düzenleyicileri, repellent vb maddeleri içermektedir. Buna karşılık pestisit terimi daha geniş bir içeriğe sahip olarak bitkisel üretim dışında kullanılan biyosit ve veteriner ilaçlarını da kapsamaktadır. Bitki koruma ürünleri mevzuat gereği ruhsatlandırmaya tabi olan ürünlerdir. Zararlı organizmalarla savaşımda pestisitlerekolayca ulaşılabilmesi, kolaylıkla uygulanabilmeleri ve hızlı etki göstermeleri nedeniyle genellikle kimyasal mücadele yöntemi tercih edilmektedir. Ancak hatalı ve/veya bilinçsiz pestisit kullanımı insan, bitki, çevre, yaban hayatı ve halk sağlığı bakımından telafisi olmayan zararlanmalara neden olabilmektedir. Bu derleme ile, böylesine geniş bir kitleyi doğrudan ilgilendiren bitki koruma ürünlerinin ruhsatlandırılmasına ilişkin mevzuat ile gerek akademik camianın ve gerekse bu ürünlerin ithal, imal veya ihracını yapan pestisit sektörünün dikkatinin çekilmesi amaçlanmaktadır. Bu amaçla 1957, 1958, 1995, 1999, 2009, 2010, 2011 yıllarında yayımlanan ruhsatlandırma ile ilgili yönetmelikler 2017 yılında yayımlanan güncel yönetmelikle kıyaslamalı olarak tartışılarak ruhsatlandırmanın gelişimi tarihsel süreçte irdelenmiştir.

humankind has begun to be influential in climate change. Industrial revolution
lead to unsteady greenhouse gases emissions that led to the global warming and
consequent climate change impacts at different scales in various regions of the
world. Accordingly, the seasonal periods started to change especially for
seasons of Spring and Fall and consequently undesirable changes in the natural events started to occur such as excessive rain, outdoor temperatures above
seasonal normal levels. Nowadays, global climate change is one of the most
significant problems that mankind has to front with respect to its results. Due
to global warming the Turkish province of Sivas is in a sensitive position
because of its location. In this study, Sivas province is studied in terms of
monthly and seasonal temperature trends. The temperature trends are analyzed by
the use of linear regression techniques and the results indicate a significant
rise in temperature trends.
