Mevcut
çalışmada, Cladonia furcata (Huds.) Schrad. likeninden elde edilen metanol ve su ekstraktlarının (sırasıyla CME ve CSE) insan lenfositleri
üzerindeki aktivitelerinin değerlendirilmesi amaçlanmıştır. Lenfositlerdeki sitotoksik
etkiyi test etmek için 3-(4,5-dimetiltiazol-2-il)-2,5-difeniltetrazolyum bromür
ve laktat dehidrogenaz testleri kullanılmıştır. Ayrıca, hücrelerdeki oksidatif stres ve genotoksisite değişimleri sırasıyla toplam oksidan durum ve 8-hidroksi-2'-deoksiguanozin seviyeleri ile incelenmiştir. Bu uygulamalara ek olarak, ekstraktlar ile muamele edilen lenfositlerdeki toplam antioksidan kapasite (TAK) değişimleri de belirlenmiştir. CSE'nin düşük konsantrasyonlarının yüksek seviyelerde sitotoksik etki göstermedikleri
ortaya çıkarılmıştır (IC50=221,14 mg/L). Gerçekleştirilen korelasyon analizleri sitotoksisitenin oksidatif stres ile ilişkili (p &lt; 0.01) olduğunu
göstermiştir. Tüm uygulamalar göz önüne alındığında, özellikle CSE'nin negatif kontrole kıyasla hücreler üzerinde istatistiksel olarak (p &gt;0,0,5) genetik hasar meydana getirmediği
tespit edilmiştir. Hücrelerdeki TAK temel alındığında, ekstraktların belli konsantrasyonlarının (12,5-50 mg/L) TAK'yi anlamlı derecede (p &lt;0,05) yükselttiği dikkat çekmektedir. Sonuç olarak elde edilen veriler, özellikle CSE'nin lenfositler üzeride genotoksik ve oksidatif strese neden olmayarak, yüksek antioksidan özellikleri sayesinde yeni bir tedavi maddesi kaynağı olabileceğini ortaya çıkarmıştır.

Published: March 2018

Abstract
As the capital and a major political hub for China, Beijing has undergone a rapid urbanization effect with significant population growth in recent years. At the same time, Beijing has also been suffering from severe water problems such as water scarcity, urban flooding and other issues related to water pollution. These have increasingly generated severe water problems and stymied the pace and scope of sustainable urban development. The critical challenges faced by water resource administrations pertains to the issues of sustainable management of water resources and the relevant actions to be put in place in order to address these water-related problems. In this study, the current water situation of Beijing is described in great detail focusing on water resource amounts, water supply, water consumption and water pollution changes analyzed from historical to recent years. The challenges of Beijing urban water management systems are also analyzed to offer possible solutions in light of the current trends. Finally, a number of useful strategies and action-oriented measures are provided for Beijing's urban water resource administration to assist them in overcoming the current water management challenges and for them to move towards a more sustainable developmental city.

Published: March 2018

Objective:
To describe the clinical, laboratory, microbiological, and echocardiographic findings in four intravenous drug users with endocarditis hospitalized and followed in our Infectious Disease Service, a tertiary university hospital as well as to determine the efficacy of medical treatment.

Methods:
From a database of 35 subjects with endocarditis during five years, we made a retrospective analysis of data for four cases between the age of 24-33 years old which were intravenous drug users.

Results:
Infective endocarditis was encountered in four drug users with positive blood cultures (Staphylococcus aureus was present in all the cases), vegetations in the tricuspid native valve in ultrasound, high fever (more than 38oC). The four cases were male and the mean age was 29 years (range 24-33 years). Three out of the four cases presented with pulmonary involvement and only one with femoral and popliteal vein thrombosis. Two out of four cases had acute renal and hepatic failure and only one had acute cutaneous vasculitis. Transesophageal Echocardiography (TEE) was also performed in two cases. For all of them medical management consisted of antibiotic therapy and two out of them underwent surgery because of the persistence of valvular vegetations after antibiotic therapy. The prognosis was good with 0% mortality.

Conclusion:
Infective endocarditis should be considered in the differential diagnosis of intravenous drug users presenting with various clinical scenarios. Echocardiography remains the main modality and should be used serially to facilitate early diagnosis. The successful management of a complicated case often requires the close cooperation of an infectious disease physician, a cardiologist, an addiction physician and occasionally a cardiac surgeon.

This study aims to assess the benefits and harms of laptops use by graduate students in the classroom learning, and to identify strategies for effective use of laptops in class. The study is exploratory, using 26 point questionnaire to collect data from 68 respondents. Results showed 73.5 percents use laptops in the classroom, the majority of users (63%) find it useful for browsing for relevant articles and making class notes. Many use laptops for activities unrelated to learning, such as browsing news, communicate through emails (16-22 percent) and chatting. Thirty percent of users reported to give only 25 to 50% of attention to the ongoing class activities. Users and non users had different views about laptops use in the classroom; some students perceive laptops use in class interfere with concentration, and can be an indication of â€˜disrespectâ€™ to the lecturers or other students. Lecturers should design the integration of laptop use within classroom learning activities to enrich the learning material, to make the classroom learning process become more interesting and effective.Â ABSTRAKPenelitian ini bertujuan mengkaji manfaat dan mudharat penggunaan laptop oleh mahasiswa di dalam perkuliahan serta mengidentifikasi strategi penggunaan laptop yang efektif di dalam kelas.

Published: March 2018

La pareja como unidad vincular parece ser una definición evidente; sin embargo, un abordaje más cuidadoso exige tener en cuenta el contexto donde se fundamenta, los participantes y los términos que la definen. Al respecto se han realizado numerosos estudios, que han ocupado un importante lugar en la psicología, la historia y la antropología, y han permitido una base importante para la comprensión de diversas aristas de la relación de pareja, que para el caso del propósito de este artículo están en función de los recursos personales y vinculares de los que se valen las parejas que perduran en el tiempo, de manera satisfactoria y enriquecedora para sus miembros. El artículo surge en el seno de la línea de investigación en Familia, liderada desde el Centro de Familia de la Universidad Católica de Pereira, desde las categorías teóricas que se vienen trabajando en los procesos investigativos en este campo. Después de una revisión de la literatura disponible, se encontró que el amor tiene una importancia especial en el trato afectivo en la pareja. Igualmente, la comunicación dentro de la pareja es fundamental para el funcionamiento de la relación, aunado a la capacidad para compartir sentimientos, confiar, sentirse acompañado y saber que el otro tiene los mismos intereses para la relación.
Ag doped TiO2 nanoparticles prepared by hydrothermal method and coating of the nanoparticles on the ceramic pellets for photocatalytic study: Surface properties and photoactivity

Published: March 2018

In this work, Ag doped nano TiO2 photocatalysts were synthesized in powder form by hydrothermal method at 180 ºC in 120 min using different reduction agents. The synthesized powders were characterized by powder X-ray diffraction (XRD), Energydispersive X-ray spectroscopy (EDS), Surface area measurements (BET), Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) analyses. The effect of reduction agents on the morphological properties of Ag doped nano TiO2 has been studied. We have been observed that the use of different reduction agents affects the particle size and surface area. Ag doped nano TiO2 photocatalysts were coated to the ceramic pellets by dip coating technique for photocatalytic study. Photocatalytic properties of the synthesized powder were examined in a circulating aquarium filled with indigo blue (IB) solution under UV irradiation. Periodical UV spectrophotometric analysis showed that indigo blue (IB) has been degraded and its concentration has decreased under UV irradiation by time.
A Deep X-Ray View of the Synchrotron-dominated Supernova Remnant G330.2+1.0
Authors: Williams Brian J. , Hewitt John W. , Petre Robert , Temim Tea 
Published: March 2018

Abstract
We present moderately deep (125 ks) XMM-Newton observations of supernova remnant G330.2+1.0. This remnant is one of only a few known that fall into the “synchrotron-dominated” category, with the emission almost entirely dominated by a nonthermal continuum. Previous X-ray observations could only characterize the spectra of a few regions. Here, we examine the spectra from 14 regions surrounding the entire rim, finding that the spectral properties of the nonthermal emission do not vary significantly in any systematic way from one part of the forward shock to another, unlike several other remnants of this class. We confirm earlier findings that the power-law index, Γ, ranges from about 2.1–2.5, while the absorbing column density is generally between (2.0–2.6) × 1022 cm−2. Fits with the srcut model find values of the roll-off frequency in the range of 1017.1–1017.5 Hz, implying energies of accelerated electrons of ∼100 TeV. These values imply a high shock velocity of ∼4600 km s−1, favoring a young age of the remnant. Diffuse emission from the interior is nonthermal in origin as well, and fits to these regions yield similar values to those along the rim, also implying a young age. Thermal emission is present in the east, and the spectrum is consistent with a ∼650 km s−1 shock wave encountering interstellar or circumstellar material with a density of ∼1 cm−3.
Identifying Young Kepler Planet Host Stars from Keck–HIRES Spectra of Lithium*
Authors: Berger Travis A. , Howard Andrew W. , Boesgaard Ann Merchant 
Published: March 2018

Abstract
The lithium doublet at 6708 Å provides an age diagnostic for main sequence FGK dwarfs. We measured the abundance of lithium in 1305 stars with detected transiting planets from the Kepler mission using high-resolution spectroscopy. Our catalog of lithium measurements from this sample has a range of abundance from A(Li) = 3.11 ± 0.07 to an upper limit of −0.84 dex. For a magnitude-limited sample that comprises 960 of the 1305 stars, our Keck–HIRES spectra have a median signal-to-noise ratio of 45 per pixel at ∼6700 Å with spectral resolution

= R = 55,000. We identify 80 young stars that have A(Li) values greater than the Hyades at their respective effective temperatures; these stars are younger than ∼650 Myr, the approximate age of the Hyades. We then compare the distribution of A(Li) with planet size, multiplicity, orbital period, and insolation flux. We find larger planets preferentially in younger systems, with an A–D two-sided test p-value = 0.002, a > 3σ confidence that the older and younger planet samples do not come from the same parent distribution. This is consistent with planet inflation/photoevaporation at early ages. The other planet parameters (Kepler planet multiplicity, orbital period, and insolation flux) are uncorrelated with age.
