HIV a disease caused by virus which suppress the immune system in infected person , and ready to get infected with some diseases which my effect his life. The HiV first discovered in last century with bleeding patients exposed to infected blood transfusion . national Libyan survey show prevalence of the disease as 0.13% in 2005 . people exposed to social stigma due to people knowledge about the disease and way of transmission .
Present study include 151 participants student from Benghazi University, to know their knowledge about disease transmission. The study concluded that 73.5% know that it is infected disease , 19.0% thought it transmitted by mosquito ,14.7% only think that infected person can get married . however, the study show a need for more health education activities specially among youth for better understanding about the disease and risk of getting infected.

ان الماء هو مصدر الحياة ، إذ يقول الله تعالى : في كتابه العزيز فً الآية الثلاثين من سورة الانبياء" وجعلنا من الماء كل شيء حي" صدق الله العظٌم
مشكلة المياه ليست جديدة بل قديمة قدم الحضارات الإنسانية ، فكثٌيراً ما حدثت الهجرات ونزحت الجماعات بسبب الجفاف وانقطاع الأمطار . ومن خلال تتبعنا لتاريخ الصراع العربي اليهودي لليهود ال نجده يدور حول أمرين اساسين هما : الأرض ، والماء . فكانت الأرض عاملاً مهما لليهود لاستقبال الالاف من المهاجرين إلى فلسطين من مختلف أنحاء العالم ، وعندما حققوا في هذا الجانب بعض التقدم، عن طريق المساندة البريطانية ، أصبح الماء المشكلة الوحيدة أو المهمة أمام الساسة اليهود ، ونتيجة لقلة الموارد المائية في فلسطٌين وكثرة استهلاكها ، قام الٌهود بالاعتداء على الدول العربية المجاورة لها ، من أجل السيطرة على مصادر المياه بها ، فجميع الحروب التي دارت بين العرب واليهود ، كان من نتائجها سيطرة الٌيود على مصادر المياه ، فبعد حرب 1967 م سيطر اليهود على هضبة الجولان والضفة الغربية و قطاع غزة وهي جميعاً مناطق ذات ثروة مائية ، وفي سنة 1982 م استطاع اليهود السيطرة على حوالي 30 كم من نهر الليطاني ، وذلك بحجة مطاردة الثوار الفلسطينيين في جنوب لبنان

Published: February 2020

Las lesiones causadas por caída libre son una de las principales causas de trauma en todos los países y tienden a mostrar patrón único en comparaciones con otros accidentes. Los pacientes que sobreviven a la caída libre tienden a sufrir varias lesiones, aquello recibe el nombre de politraumatismo por caída libre. Yo presento un caso de un pintor que cayó desde un techo de 3 pisos de altura. El paciente sufrió varias lesiones secundario a la caída: hematoma epidural derecho pequeño, fractura lineal no deprimida del cráneo, hematoma periocular derecho, contusión pulmonar izquierda leve, y un neumotórax menor del 5%. El paciente recibió manitol y fenitoína por 48 horas para tratar el trauma craneoencefálico y prevenir convulsiones respectivamente. El hematoma epidural derecho y fracturas faciales se manejaron de forma conservadora (no operativo). El hematoma periocular derecho disminuyó, permitiendo la apertura ocular derecha; el servicio de oftalmología evaluó al paciente y descartó déficits visuales en el paciente secundario a la caída. Se le da egreso al paciente con resolución del dolor, y sin déficits neurológicos motor o sensitivo.

Published: February 2020

O artigo tem o intuito de discorrer sobre o uso das novas tecnologias da informação e comunicação na prática docente. Para isso, foi realizado um levantamento bibliográfico sobre as tecnologias da informação e comunicação no processo de ensino aprendizagem no qual foi possível obter informações sobre o conhecimento, utilização e contribuição das tecnologias na prática pedagógica. A metodologia adotada nessa pesquisa é a revisão da literatura. A ação educativa, com o envolvimento das TIC’s, poderá ser desenvolvida na perspectiva de promover a experimentação, a descoberta e a construção de aprendizagem significativa. A mediação do processo de ensino aprendizagem com o uso dessas ferramentas requer uma avaliação tanto do processo quanto do resultado. A escola não está alheia à sociedade, mas imersa nela e, assim, é influenciada o tempo todo pelas modificações ocorridas em todas as esferas. As tecnologias de informação (TIC’s) são relevantes para o processo de ensino-aprendizagem, e seu uso de maneira crítica e criativa possibilita o desenvolvimento do estudante. Porém, para que isso realmente aconteça são necessárias competências e habilidades tecnológicas e pedagógicas do docente para mediar a construção do conhecimento.
Learning is negatively associated with strength of left/right paw preference in wild grey squirrels (Sciurus carolinensis)
Authors: Leaver Lisa A. , Ford Steph , Miller Christopher W. , Yeo Matilda K. , Fawcett Tim W. 
Published: February 2020

AbstractCerebral laterality, via hemispheric specialisation, has been evidenced across the animal kingdom and linked to cognitive performance in a number of species. Previously it has been suggested that cognitive processing is more efficient in brains with stronger hemispheric differences in processing, which may be the key fitness benefit driving the evolution of laterality. However, evidence supporting a positive association between cognitive performance and lateralization is mixed: data from studies of fish and birds show a positive relationship whereas more limited data from studies of mammals suggest a weak or even negative relationship, suggesting the intriguing possibility of a mammal/non-mammal divide in the nature of this relationship. Here, we report an empirical test examining the relationship between lateralization and cognitive performance in wild grey squirrels (Sciurus carolinensis) by measuring left/right paw preference as a behavioural assay of cerebral lateralization and learning speed as an assay of cognitive efficiency. We carried out a motor-based laterality test using a reaching paradigm and measured learning speed on a problem-solving task. In accordance with the suggestion of a mammal/non-mammal divide, we found a negative relationship between strength of paw preference and performance on the learning task. We discuss this finding in light of niche-specific adaptations, task-specific demands and cognitive flexibility.
Tracking of unpredictable moving stimuli by pigeons
Authors: Wilkinson Anna , Kirkpatrick Kimberly 
Published: February 2020

AbstractDespite being observed throughout the animal kingdom, catching a moving object is a complex task and little is known about the mechanisms that underlie this behavior in non-human animals. Three experiments examined the role of prediction in capture of a moving object by pigeons. In Experiment 1, a stimulus moved in a linear trajectory, but sometimes made an unexpected 90oturn. The sudden turn had only a modest effect on capture and error location, and the analyses suggested that the birds had adjusted their tracking to the novel motion. In Experiment 2, the role of visual input during a turn was tested by inserting disappearances (either 1.5 cm or 4.5 cm) on both the straight and turn trials. The addition of the disappearance had little effect on capture success, but delayed capture location with the larger disappearance leading to greater delay. Error analyses indicated that the birds adapted to the post-turn, post-disappearance motion. Experiment 3 tested the role of visual input when the motion disappeared behind an occluder and emerged in either a straight line or at a 90oangle. The occluder produced a disruption in capture success but did not delay capture. Error analyses indicated that the birds did not adjust their tracking to the new motion on turn trials following occlusion. The combined results indicate that pigeons can anticipate the future position of a stimulus, and can adapt to sudden, unpredictable changes in motion but do so better after a disappearance than after an occlusion.

Abstract
We report the discovery of an extreme X-ray flux rise (by a factor of ≳20) of the weak-line quasar Sloan Digital Sky Survey (SDSS) J153913.47+395423.4 (hereafter SDSS J1539+3954) at z = 1.935. SDSS J1539+3954 is the most-luminous object among radio-quiet type 1 active galactic nuclei (AGNs) where such dramatic X-ray variability has been observed. Before the X-ray flux rise, SDSS J1539+3954 appeared X-ray weak compared with the expectation from its ultraviolet (UV) flux; after the rise, the ratio of its X-ray flux and UV flux is consistent with the majority of the AGN population. We also present a contemporaneous HET spectrum of SDSS J1539+3954, which demonstrates that its UV continuum level remains generally unchanged despite the dramatic increase in the X-ray flux, and its C iv emission line remains weak. The dramatic change only observed in the X-ray flux is consistent with a shielding model, where a thick inner accretion disk can block our line of sight to the central X-ray source. This thick inner accretion disk can also block the nuclear ionizing photons from reaching the high-ionization broad emission-line region, so that weak high-ionization emission lines are observed. Under this scenario, the extreme X-ray variability event may be caused by slight variations in the thickness of the disk. This event might also be explained by gravitational light-bending effects in a reflection model.
Identification of QPO Frequency of GRS 1915+105 as the Relativistic Dynamic Frequency of a Truncated Accretion Disk

Published: February 2020

Abstract
We have analyzed AstroSat observations of the galactic microquasar system GRS 1915+105, when the system exhibited C-type quasi-periodic oscillations (QPOs) in the frequency range of 3.4–5.4 Hz. The broadband spectra (1–50 keV) obtained simultaneously from the Large Area X-ray Proportional Counter and Soft X-ray Telescope can be well described by a dominant relativistic truncated accretion disk along with thermal Comptonization and reflection. We find that while the QPO frequency depends on the inner radii with a large scatter, a much tighter correlation is obtained when both the inner radii and accretion rate of the disk are taken into account. In fact, the frequency varies just as the dynamic frequency (i.e., the inverse of the sound crossing time) does as predicted decades ago by the relativistic standard accretion disk theory for a black hole with a spin parameter of ∼0.9. We show that this identification has been possible due to the simultaneous broadband spectral coverage with temporal information as obtained from AstroSat.

Published: February 2020

Systematic data collection on species and their exploited environments is of key importance for conservation studies. Within the less-known environments, the subterranean ones are neither easy to be studied, nor to be explored. Subterranean environments house a wide number of specialised organisms, many of which show high sensitivity to habitat alteration. Despite the undeniable importance to monitor the status of the subterranean biodiversity, standardised methodologies to record biotic and abiotic data in these environments are still not fully adopted, impeding therefore the creation of comparable datasets useful for monitoring the ecological condition in the subterranean environments and for conservation assessment of related species.
In this work we describe a methodology allowing the collection of standardised abiotic and biotic data in subterranean environments. To show this, we created a large dataset including information on environmental features (morphology and microclimate) and abundance of five predators (one salamander, three spiders and one snail) occurring in seven caves of the Monte Albo (Sardinia, Italy), an important biodiversity hotspot. We performed 77 surveys on 5,748 m2 of subterranean environments througout a year, recording 1,695 observations of the five cave predators. The fine-scale data collection adopted in our methodology allowed us to record detailed information related to both morphology and microclimate of the cave inner environment. Furthermore, this method allows us to account for species-imperfect detection when recording presence/abundance data.
Piriformis Syndrome
Authors: Foster Mark R 
Published: February 2020

AbstractSeven patients underwent release of the piriformis from the femur. Patients with residual symptoms after conservative treatment had dramatic relief of sciatica and 70% resumed customary work after surgery. Minimum followup was 31 montiis (average: 51 months). Early diagnosis can avoid prolonging ineffective empiric treatment and disability with satisfactory results achieved in most patients by conservative treatment and relief of sciatica in selected surgical cases.
Observationally constrained modeling of atmospheric oxidation capacity and photochemical reactivity in Shanghai, China

Published: February 2020

Abstract. An observation-based model coupled to the Master Chemical Mechanism (V3.3.1)
and constrained by a full suite of observations was developed to study
atmospheric oxidation capacity (AOC), OH reactivity, OH chain length and
HOx (=OH+HO2) budget for three different ozone (O3)
concentration levels in Shanghai, China. Five months of observations from 1 May to 30 September 2018 showed that the air quality level is lightly
polluted or worse (Ambient Air Quality Index, AQI, of > 100) for
12 d, of which ozone is the primary pollutant for 10 d, indicating
ozone pollution was the main air quality challenge in Shanghai during
summer of 2018. The levels of ozone and its precursors, as well as
meteorological parameters, revealed the significant differences among
different ozone levels, indicating that the high level of precursors is the
precondition of ozone pollution, and strong radiation is an essential
driving force. By increasing the input JNO2 value by 40 %, the
simulated O3 level increased by 30 %–40 % correspondingly under the
same level of precursors. The simulation results show that AOC, dominated by
reactions involving OH radicals during the daytime, has a positive
correlation with ozone levels. The reactions with non-methane volatile
organic compounds (NMVOCs; 30 %–36 %), carbon monoxide (CO; 26 %–31 %) and nitrogen dioxide (NO2; 21 %–29 %) dominated
the OH reactivity under different ozone levels in Shanghai. Among the
NMVOCs, alkenes and oxygenated VOCs (OVOCs) played a key role in OH
reactivity, defined as the inverse of the OH lifetime. A longer OH chain
length was found in clean conditions primarily due to low NO2 in the
atmosphere. The high level of radical precursors (e.g., O3, HONO and
OVOCs) promotes the production and cycling of HOx, and the daytime
HOx primary source shifted from HONO photolysis in the morning to
O3 photolysis in the afternoon. For the sinks of radicals, the reaction
with NO2 dominated radical termination during the morning rush hour,
while the reactions of radical–radical also contributed to the sinks of
HOx in the afternoon. Furthermore, the top four species contributing to
ozone formation potential (OFP) were HCHO, toluene, ethylene and
m/p-xylene. The concentration ratio (∼23 %) of these four
species to total NMVOCs is not proportional to their contribution
(∼55 %) to OFP, implying that controlling key VOC species
emission is more effective than limiting the total concentration of VOC in
preventing and controlling ozone pollution.
Precariedad y exilio en la juventud española actual. Discursos y semblanzas periodísticas de la crisis. 2008-2016
Authors: Angulo Egea María 
Published: February 2020

La crisis económica iniciada en 2008 ha potenciado la vulnerabilidad de ciertos grupos sociales como los jóvenes. Los efectos de la crisis se han cebado en una juventud española que padece los peores parámetros sociales de la Unión Europea. Jóvenes con el mejor nivel de estudios de la historia de España pero que se encuentran precarizados y abocados al exilio. Jóvenes con una clara falta de perspectivas y frustración, que ven imposible acceder a algo medianamente relacionado con aquello para lo que se formaron.
Este artículo atiente a las circunstancias socioculturales que envuelven el discurso sobre la juventud española emigrante durante la crisis de 2008. Se trata de comprender el imaginario que se ha volcado sobre estos jóvenes exiliados con estudios superiores desde los medios de comunicación. Se presentan las narrativas que rodean a la juventud y en concreto se analizan dos relatos autobiográficos de jóvenes periodistas emigrantes, sus “historias de vida”, para determinar los parámetros del discurso y el perfil de las semblanzas de estos jóvenes precarios exiliados.
“The Kinematograph View of Life”: Cinema, Fiction & Periodicals in Britain, 1910–20
Authors: Cranfield Jonathan 
Published: February 2020

ABSTRACTThis article examines the depiction of cinemas and film culture in mainstream literary periodicals between 1910 and 1920. It focuses on the role played by illustrated magazines (Quiver, the Pall Mall Magazine and the Strand) in legitimizing film as an art form and countering accusations of immorality from anti-cinema activists. It also looks at the role played by early cinema fiction within this discourse. The final section explores the changes to authorship wrought by the globalization of cinema and the periodical press during and immediately after the First World War.
Wyndham Lewis, Cicely Hamilton, and Nazi Germany in Time and Tide
Authors: Einhaus Ann-Marie 
Published: February 2020

ABSTRACT
This article scrutinizes the contributions of Wyndham Lewis and Cicely Hamilton to coverage of Germany in the weekly review Time and Tide leading up to and following the National Socialist parliamentary election victory in September 1930. The magazine’s coverage of this crucial period in German interwar politics is used as a lens to explore its wider attitudes towards internationalism between the wars. Reading Lewis’s and Hamilton’s contributions against each other sheds new light on the crucial role played by Time and Tide in negotiating its readers’ course through the fraught political and cultural landscape of interwar Europe.
Periodical Insurrections: Revival, Modernism, and the Irish Review
Authors: Bruna Giulia 
Published: February 2020

ABSTRACT
Known for having among its editors revolutionaries who died in the 1916 Easter Rising and for combining militant Manifestos of the Irish Volunteers with revivalist literary work, The Irish Review (1911–14) also engaged with wider modernist movements and trends. Building on recent criticism on the periodical, on scholarship about Revival and modernist print cultures, and on archival material (editors’ letters, business correspondence, and ephemera), this essay illuminates the Review’s transnational and transatlantic connections with contemporaneous literary periodicals in Ireland, Europe, and the USA. By analyzing its significant modernist content, the essay will also examine the Review’s approach to modernist poetics.
Rising and Falling on the Price of Paper: The Story ofMandrake
Authors: Falcetta Jennie-Rebecca 
Published: February 2020

ABSTRACTFounded at Oxford by John Wain, Mandrake (1945–1956) aspired to be more than an undergraduate poetry magazine. Under the capable hands of subsequent editor Arthur Boyars, the journal raised its profile. However, despite a double issue focusing on Italian Arts, early poems by Kingsley Amis and Philip Larkin, and committed intellectual engagement with postwar letters, Mandrake has not received sustained critical attention. This article draws upon personal interviews with editor Boyars and archival material to reconstruct and retell the story of Mandrake, hoping to convey its context and its value within the field of periodical studies.
