    During the eight weeks working at NASA, I was fortunate enough to work with the Expendable Launch Vehicle's (ELV) Electromagnetic Compatibility (EMC) Team, who is responsible for the evaluation and analysis of any EMI risk an ELV mission might face. This group of people concern themselves with practically any form of electromagnetic interference that may risk the safety of a rocket, a mission, or even people. Taking this into consideration, the group investigates natural forms of interference, such as lightning, to manmade interferences, such as antennas.

    Background:There are few studies for evaluating wall characteristics of intracranial vertebral artery hypoplasia (VAH).The aim of this study was to determine wall characteristics of VAH with three-dimensional volumetric isotropic turbo spin echo acquisition (3D VISTA) images and differentiate between acquired atherosclerotic stenosis and VAH.Methods:Thirty patients with suspicious VAH by luminograms were retrospectively enrolled between January 2014 and February 2015.The patients were classified as "acquired atherosclerotic stenosis" or "VAH" based on 3D VISTA images.The wall characteristics of VAH were assessed to determine the presence of atherosclerotic lesions,and the patients were classified into two subgroups (VAH with atherosclerosis and VAH with normal wall).Wall characteristics of basilar arteries and vertebral arteries were also assessed.The clinical and wall characteristics were compared between the two groups.Results:Five of 30 patients with suspicious VAH were finally diagnosed as acquired atherosclerotic stenosis by 3D VISTA images.25 patients were finally diagnosed as VAH including 16 (64.00%) patients with atherosclerosis and 9 (36.00%) patients with normal wall.In the 16 patients with atherosclerosis,plaque was found in 9 patients,slight wall thickening in 6 patients,and thrombus and wall thickening in 1 patient.Compared with VAH patients with normal wall,VAH patients with atherosclerosis showed atherosclerotic basilar arteries and dominant vertebral arteries more frequently (P =0.000).Conclusions:Three-dimensional VISTA images enable differentiation between the acquired atherosclerotic stenosis and VAH.VAH was also prone to atherosclerotic processes.

    Objective To explore the prevalence of vertebral artery dysplasia (VAH)and its risk and regularity of poste-rior circulation infarction (PCI)in vertigo patients with VAH.Method We sequentially enrolled 245 patients suspected of vas-cular vertigo,detected by Magnetic Resonance Angiography (MRA)to judge if merged with VAH,who were divided into cere-bral infarction group and non-infarction group according to whether VAH formed fresh infarction or not measured by Diffu-sion-weighted Imaging (DWI).Univariate and multivariate logistic regression analyses were performed to identify significant risk factors for PCI stroke.Finally,we analyzed the characteristics and regularity of PCI with VAH.Result The prevalence of VAH was 26.1% in vertigo patients.Multivariate logistic regression analysis showed that VAH (OR=2.59,95%CI:1.07-6. 27,P=0.035),stenosis of the posterior circulation (OR=6.04,95%CI:1.94-1 7.07,P=0.002)and diabetes mellitus (OR=3.21,95%CI:1.36-7.57,P=0.008)were independent risk factors for PCI.The TOAST subtypes of PCI with VAH were mainly attributed to small arteries occlusions (10/18).8 patients with cerebral infarctions which were located at pons,thala-mus and temporal occipital lobe infarction occurred on the opposite VAH,4 patients with cerebellar and medullary infarction occurred in the ipsilateral VAH (4/6).Conclusion VAH is common in vertigo patients,which may be an independent risk factor for PCI with certain regularity of its infarction distribution.%目的:探讨椎动脉发育不良(vertebralartery dysplasia,VAH)在眩晕患者中的发生率及其相关后循环梗死的规律和危险性。方法连续入组245例眩晕患者(可疑为血管性),采用磁共振血管成像检查合并 VAH 情况,根据磁共振弥散加权成像是否出现后循环新鲜梗死灶分为梗死组和非梗死组,对相关血管危险因素进行单因素和多因素分析;并分析 VAH合并后循环梗死的特点和规律。结果VAH 发生率26.1%(64/245)

    2016-12-01

    On the basis of a Langmuir-Hinshelwood-type mechanism, the dehydrogenation of ethylene, acetic acid and hydrogenated vinyl acetate (VAH) on pure Pd(1 0 0) with surface oxygen atoms (Os) and hydroxyl groups (OHs) was studied with density functional theory (DFT) method. Our calculation results show that both Os and OHs can consistently reduce the activation energies of dehydrogenation of ethylene, acetic acid and VAH to some degree with only one exception that OHs somehow increase the activation energy of VAH. Based on Langmuir-Hinshelwood mechanism, the three dehydrogenation reactions in presence of surface Os and OHs are almost consistently favored, compared with the corresponding processes on clean Pd(1 0 0) surfaces, and thus a Langmuir-Hinshelwood-type mechanism may not be excluded beforehand when investigating the microscopic performance of the oxygen-assisted vinyl acetate synthesis on Pd(1 0 0) catalysts.

    Full Text Available Lineages of hypervirulent Aeromonas hydrophila (vAh are the cause of persistent outbreaks of motile Aeromonas septicemia in warm-water fishes worldwide. Over the last decade, in the People’s Republic of China and in the United States, this virulent lineage of A. hydrophila has resulted in annual losses of millions of tons of farmed carp and catfish. Multiple lines of evidence indicate that US catfish and Asian carp isolates of A. hydrophila affiliated with sequence type 251 (ST251 share a recent common ancestor. To address the genomic context for the putative intercontinental transfer and subsequent geographic spread of this pathogen, we conducted a core genome phylogenetic analysis on 61 Aeromonas spp. genomes, of which 40 were affiliated with A. hydrophila and 26 were epidemic strains. Phylogenetic analyses indicate that all ST251 strains form a coherent lineage affiliated with A. hydrophila. Within this lineage, conserved genetic loci were identified that are unique within A. hydrophila as well as genes that are present in consistently higher copy numbers than in non-epidemic A. hydrophila isolates. In addition, results from analyses of representative ST251 isolates supports that multiple lineages are present within US vAh isolated from Mississippi, whereas vAh isolated from Alabama appear clonal. This is the first report of genomic heterogeneity within US vAh isolates, with some Mississippi isolates showing closer affiliation with the Asian grass carp isolate ZC1 than with other vAh isolated in the US. To evaluate the biological significance of the identified heterogeneity, comparative disease challenges were conducted with representatives of different vAh genotypes revealing that isolate ZC1 yielded significantly lower mortality in channel catfish, relative to Alabama and Mississippi vAh isolates. Like other Asian vAh isolates, the ZC1 lineage contains all core genes for a complete type VI secretion system (T6SS. In contrast, more

    Ventilatory acclimatization to hypoxia (VAH) increases the hypoxic ventilatory response (HVR) and causes persistent hyperventilation when normoxia is restored, which is consistent with the occurrence of synaptic plasticity in acclimatized animals. Recently, we demonstrated that antagonism of individual glutamate receptor types (GluRs) within the nucleus tractus solitarii (NTS) modifies this plasticity and VAH (J. Physiol. 592(8):1839-1856); however, the effects of combined GluR antagonism remain unknown in awake rats. To evaluate this, we exposed rats to room air or chronic sustained hypobaric hypoxia (CSH, PiO2 = 70 Torr) for 7-9 days. On the experimental day, we microinjected artificial cerebrospinal fluid (ACSF: sham) and then a "cocktail" of the GluR antagonists MK-801 and DNQX into the NTS. The location of injection sites in the NTS was confirmed by glutamate injections on a day before the experiment and with histology following the experiment. Ventilation was measured in awake, unrestrained rats breathing normoxia or acute hypoxia (10% O2) in 15-min intervals using barometric pressure plethysmography. In control (CON) rats, acute hypoxia increased ventilation; NTS microinjections of GluR antagonists, but not ACSF, significantly decreased ventilation and breathing frequency in acute hypoxia but not normoxia (P NTS significantly decreased ventilation in normoxia and breathing frequency in hypoxia. A persistent HVR after combined GluR blockade in the NTS contrasts with the effect of individual GluR blockade and also with results in anesthetized rats. Our findings support the hypotheses that GluRs in the NTS contribute to, but cannot completely explain, VAH in awake rats.

    This study explored the journey of American armed forces personnel from their decision to join the service, through their service in an active military conflict and how these factors may be associated with potential resistance for mental healthcare. The data came from qualitative interviews with 46 OIF/OEF/OND active-duty military, reservists, and discharged veterans of the average age of 25 years, who presented for a new episode of mental health treatment to a large Veterans Affairs Hospital (VAH) in Northeastern United States in 2011-2012. Qualitative analysis of veterans' perceptions revealed several major themes describing how a mental health diagnosis would negatively impact both their sense of identity and pragmatic career-building goals: enlisting as a career-building avenue, 'noble superhero' identity, escaping from hardship, and mental illness as a career-killer. Findings suggest that factors making young veterans resist mental healthcare may be reduced by partnering VAH psychiatrists with career counselors, and by enhancing military leadership's awareness and understanding about how to support soldiers with emotional and mental health needs, with a goal to eliminating stigma.

    Objective To summarize the clinical features and vascular lesions in patients who suffered from cerebellar infarction with vertebral artery hypoplasia(VAH). Methods Retrospective analysis was used in the research. The selected patients suffered from cerebellar infarction with VAH or stenosis (stenosis rate≥50%). Seventy-one patients with cerebellar infarction were enrolled. There were 34 patients in VAH group and 37 patients in vertebral artery stenosis group. The age, sex, risk factors, clinical manifestations and characteristics of vascular examination were compared. Results The age, sex, risk factors between two groups had no significant differences (P>0.05). The scores of National Institutes of Health Stroke Scale (NIHSS) between two groups had no significant difference (P>0.05). The proportion of early neurological deterioration in VAH group (41.2%, 14/34) was higher than that in vertebral artery stenosis group (18.9%, 7/37), χ2=4.21, P<0.05. There were more patients with anterior circulation artery stenosis in the VAH group (35.3%, 12/34), compared with that in artery stenosis group (13.5%, 5/37),χ2=4.62, P<0.05. Except the ipsilateral vertebral artery, other arteries stenosis in VAH group (44.1%, 15/34) was significantly higher than that in vertebral artery stenosis group (13.5%, 5/37),χ2=8.20, P<0.05. Conclusions Cerebellar infarction with vertebral artery hypoplasia is more likely to have multiple cerebral arterial stenosis (stenosis rate ≥50%). The patients who suffered from cerebellar infarction with vertebral artery hypoplasia might be prone to early neurological deterioration.%目的:总结伴有椎动脉发育不良(VAH)的小脑梗死患者的临床特征和血管病变情况。方法采用回顾性分析方法,选择伴VAH和椎动脉粥样硬化狭窄率≥50%的初发小脑梗死患者,按照椎动脉病变分为VAH组(34例)和椎动脉狭窄组(椎动脉狭窄≥50%,37例),比较两组年龄、性别构成、危险

    Transfer factor (TL) varies with alveolar volume (VA), but not in the manner implied by the carbon monoxide transfer coefficient (KCO (TL/VA)). This paper considers two other simple models (one linear and one exponential) which might standardize TL for VA, and asks the questions: 1) Is either model valid? 2) What are appropriate reference values? and 3) Will the model be useful? The relationship of TL to VA within subjects at different depths of inspiration, and between subjects having lungs of different sizes, were measured and compared. The subjects were asymptomatic, nonsmoking, Caucasian adults, including 31 males assessed in the laboratory and 503 male and female participants in population studies. The linear partial regression coefficients of TL on VA (L corrected for body temperature, atmospheric pressure and water saturation (BTPS)) standardized for height (H) in metres, were similar within- and between-subjects; the coefficients applied over a wide range of values for VA. This was not the case for the exponential model. The resulting reference equations in SI units for males and females were: TL = 11.52 H + 2.72 VA.H-2 - 0.051 Age -12.35. RSD 1.17; and TL = 4.87 H + 2.29 VA.H-2 - 0.019 Age -3.03. RSD 0.92, respectively. The residual standard deviations (RSD) about the new relationships were less than in other series. The new linear model could account for much of the variation between different published reference values for TL; it could be useful clinically, in circumstances when VA deviates from the norm. The model does not explain differences in TL associated with gender. Inclusion of VA.H-2 as a covariate in the reference equation for transfer factor, in addition to age and height, improves the accuracy of prediction of normal transfer factor compared with current reference values; its use suggests that some of the differences between published values is due to the volume term. The equations can be used clinically, and eliminate the need for carbon

    椎动脉发育不良与椎动脉先天闭塞,特别是在椎动脉的解剖变异中,是一种并不常见的后循环胚胎变异。大量数据表明在伴或不伴有基底动脉形态变异的情况下,尤其在合并了其他脑血管危险因素时,后循环缺血的发生与椎动脉发育不良有关。尽管在椎动脉发育不良的定义与评估方法上仍存在争议,既往的研究通过彩色多普勒超声发现同侧的发育不良的椎动脉净流速降低,而发育正常的椎动脉净流速代偿性的增加,导致局部血流低灌注,甚至出现临床症状,说明椎动脉发育不良具有更易于闭塞的特点,并增加了远端血栓形成的概率[1]。此外,椎动脉发育不良可能引发其他复杂的神经血管疾病如偏头痛、前庭神经元炎、发作性眩晕以及椎动脉夹层等。%As uncommon embryonic variations of posterior circulation, especially the anatomic variations of vertebral artery (VA), vertebral artery hypoplasia (VAH) and vertebral artery aplasia (VAA), with or without basilar artery morphological abnormalities, have been suggested by substantial data of having relationship with posterior circulation ischemic events, particularly in conjunction with other cerebral vascular risk factors. Inspite of disagreement existing in deifnition and evaluation methods of VAH, color Doppler ultrasonography (CDU) of previous studies have found lower net VA lfow volume of ipilateral hypoplasic artery and an increased compensatory lfow volume of non-hypoplasic artery, resulting local hypoperfusion, even clinical symptoms, illustrating the characteristics of VAH’s more vulnerable to occlusion and distal thrombosis[1]. Besides, VAH may result in other complex neurovascular consequences such as migraine, vestibular neuronitis (VN), episodic dizziness and vertebral artery dissection (VAD), etc.

    Both auditory hallucinations (AH) and visual hallucinations may occur in schizophrenia. One of the main hypotheses underlying their occurrence involves the increased activity of the mesolimbic pathway, which links the ventral tegmental area (VTA) and the nucleus accumbens (NAcc). However, the precise contribution of the mesolimbic pathway in hallucinations across various sensory modalities has not yet been explored. We compared the resting-state functional connectivity (rs-FC) of the NAcc among 16 schizophrenia patients with pure AH, 15 with both visuoauditory hallucinations (VAH), and 14 without hallucinations (NoH). A between-group comparison was performed using random-effects ANCOVA (rs-FC of the bilateral NAcc as the dependent variable, groups as the between-subjects factor, age and Positive and Negative Syndrome Scale scores as covariates; q(false discovery rate [FDR]) hallucinations, but the NAcc FC patterns changed with the complexity of these experiences (ie, 0, 1, or 2 sensory modalities), rather than with severity. This might support the aberrant salience hypothesis of schizophrenia. Moreover, these findings suggest that future clinical and neurobiological studies of hallucinations should evaluate not only the global severity of symptoms but also their sensorial features.

    Filariasis caused by infectious parasitic nematodes has been identified as the second leading source of permanent and long-term disability in Sub-Saharan Africa, Asia and Latin America. Several vaccine candidates were identified from infective third-stage larvae (L3) which involves in the critical transition from arthropod to human. Hitherto studies of these antigens in combination with alum adjuvant have shown to elicit its characteristic Th2 responses. Inulin is a safe, non-toxic adjuvant that principally stimulates the innate immune response through the alternative complement pathway. In the present study, the immune response elicited by inulin and alum as adjuvants were compared with filarial antigens from different aetiological agents: secreted larval acidic protein 1 (SLAP1) from Onchocerca volvulus and venom allergen homologue (VAH) from Brugia malayi as single or as cocktail vaccines in mice model. The study revealed that inulin can induce better humoral response against these antigens than alum adjuvant. Antibody isotyping disclosed inulin's ability to elevate the levels of IgG2a and IgG3 antibodies which mediates in complement-dependent cytotoxicity and antibody-dependent cell-mediated cytotoxicity (ADCC), respectively, in mice. Splenocyte analysis showed that T cells prestimulated with inulin have higher stimulation index (P inulin formulation had induced higher cytotoxicity with filarial antigens (as single P inulin to deplete the levels of Treg and brought a balance in Th1/Th2 arms against filarial antigens in mice.

  10. Magnetized Accretion-Ejection Structures 2.5D MHD simulations of continuous Ideal Jet launching from resistive accretion disks

    We present numerical magnetohydrodynamic (MHD) simulations of a magnetized accretion disk launching trans-Alfvenic jets. These simulations, performed in a 2.5 dimensional time-dependent polytropic resistive MHD framework, model a resistive accretion disk threaded by an initial vertical magnetic field. The resistivity is only important inside the disk, and is prescribed as eta = alpha_m V_AH exp(-2Z^2/H^2), where V_A stands for Alfven speed, H is the disk scale height and the coefficient alpha_m is smaller than unity. By performing the simulations over several tens of dynamical disk timescales, we show that the launching of a collimated outflow occurs self-consistently and the ejection of matter is continuous and quasi-stationary. These are the first ever simulations of resistive accretion disks launching non-transient ideal MHD jets. Roughly 15% of accreted mass is persistently ejected. This outflow is safely characterized as a jet since the flow becomes super-fastmagnetosonic, well-collimated and reaches a q...

    L-Dopa is the drug of choice in the treatment of Parkinson's disease but it has dose related adverse effects such as nausea, vomiting, orthostatic hypotension, end of dose deterioration, on off phenomena and on chronic therapy motor complications synonymous to parkinsonism. Mucuna pruriens (M.P) commonly known as velvet beans or cowitch are used in case of spasms associated with Parkins onism. Clinical efficacy of seeds of this plant was confirmed and the efficacy was contributed to its L-Dopa content. M.P extract showed twice the antiparkinsonism activity compared with synthetic L-Dopa. There is sufficient L-Dopa in broad bean (Vicia faba) pods. One study proved its efficacy in Parkinsonism. Ginkgo biloba extract showed protective effect in vivo and invitro. 50% ethanolic extract of Plumbago zeylanica was effective in rats. The following plants were reported to have L-Dopa but their protective effect is yet to be established in animal models. Vigna aconitifolia, Vigna unguiculata, Vigna vexillata, Prosopis chilensis, Pileostigma malabarica, Phanera vahlis, Parkinsonia acculeata, Macuna urens, Canvavalia glandiata, Cassia floribanda, Casia hirsute and Dalbergia retusa etc.

    Beaver ponds are surface-water features that are transient through space and time. Such qualities complicate the inclusion of beaver ponds in local and regional water balances, and in hydrological models, as reliable estimates of surface-water storage are difficult to acquire without time- and labour-intensive topographic surveys. A simpler approach to overcome this challenge is needed, given the abundance of the beaver ponds in North America, Eurasia, and southern South America. We investigated whether simple morphometric characteristics derived from readily available aerial imagery or quickly measured field attributes of beaver ponds can be used to approximate surface-water storage among the range of environmental settings in which beaver ponds are found. Studied were a total of 40 beaver ponds from four different sites in North and South America. The simplified volume-area-depth (V-A-h) approach, originally developed for prairie potholes, was tested. With only two measurements of pond depth and corresponding surface area, this method estimated surface-water storage in beaver ponds within 5 % on average. Beaver pond morphometry was characterized by a median basin coefficient of 0.91, and dam length and pond surface area were strongly correlated with beaver pond storage capacity, regardless of geographic setting. These attributes provide a means for coarsely estimating surface-water storage capacity in beaver ponds. Overall, this research demonstrates that reliable estimates of surface-water storage in beaver ponds only requires simple measurements derived from aerial imagery and/or brief visits to the field. Future research efforts should be directed at incorporating these simple methods into both broader beaver-related tools and catchment-scale hydrological models.

    The wetland has very important functions in hydrologic and ecological aspects and the research of wetland functions requires the basic hydrological properties such as water quantity. However, we do not have research work on the hydrological for a wetland study in Korea. Therefore, this study is to estimate the relations between the volume(V), the area(A), and the depth(h) of water in the wetland which might be the basis for the wetland research in Korea. To estimate the relations, we derive the basic equations, obtain the surveyed data and do modelling, and estimate the relations of A-h and V-h using the Surfer program. The estimated and observed volumes for 5-wetland are compared and the errors are in the range of 2% to 11% for 4-wetland and 34% for the rest. The wetlands in small errors showed the similar ones with the profile of the wetted perimeter which is assumed for the derivation of the equation but the wetland of large error has much different profile with the assumed one. We re-estimate the volumes for 3-wetland(W3, W4, W5) which showed the large errors due to the bended profiles of the wetland slope. Say, after the slopes was divided into two parts of upper and lower ones, the volumes were estimated. From our re-estimation, we obtained very good results ranged from 1% to 8% in their errors. We conjecture that the procedure suggested in this study might be useful as a reference for the future research on the relations of V-A-h in Korea. (author). 9 refs., 4 tabs., 18 figs.

    In August 2013, 200 years have passed since the greatest and most destructive floods known in the Slovak river basins. The flood affected almost the entire territory of Slovakia, northeastern Moravia, south of Poland. River basins of Váh (Orava, Kysuca), Poprad, Nitra, Hron, Torysa, Hornád, upper and middle Vistula, Odra have been most affected. The aim of this paper is to map the flood marks documenting this catastrophic flood in Slovakia. Flood marks and registrations on the 1813 flood in the Váh river basin are characterized by great diversity and are written in Bernolák modification of Slovak, in Latin, German and Hungarian. Their descriptions are stored in municipal chronicles and Slovak and Hungarian state archives. The flood in 1813 devastated the entire Váh valley, as well as its tributaries. Following flood marks were known in the Vah river basin: Dolná Lehota village in the Orava river basin, historical map from 1817 covering the Sučany village and showing three different cross-sections of the Váh river during the 1813 flood, flood mark in the city of Trenčín, Flood mark in the gate of the Brunovce mansion, cross preserved at the old linden tree at Drahovce, and some records in written documents, e.g. Cifer village. The second part of the study deals with flood marks mapping in the Hron, Hnilec and Poprad River basins, and Vistula River basin in Krakow. On the basis of literary documents and the actual measurement, we summarize the peak flow rates achieved during the floods in 1813 in the profile Hron: Banská Bystrica. According to recent situation the 1813 flood peak was approximately by 1.22 m higher, than the flood in 1974. Also in the Poprad basin is the August 1813 flood referred as the most devastating flood in last 400 years. The position of the flood mark is known, but the building was unfortunately removed later. The water level in 1813 was much higher than the water level during the recent flood in June 2010. In Cracow the water level

Methods A total of 328 hospitalized patients from April 2012 to April 2014 were enrolled retrospectively. With normal course and regular shape of basilar artery on brain magnetic resonance angiography ( MRA) , other causes of posterior circulation ischemic stroke were excluded.They were divided into BAH ( n=48 ) and non-BAH (n=280) groups according to the morphology and diameter of basilar artery on head MRA. We compared the general information and intracranial vascular variations between two groups, especially the incidence rate of posterior circulation infarction and mean blood flow velocity ( Vm ) of basal artery by analyzing clinical information and MRI findings.Meantime, their clinical outcomes were observed through follow-ups.And detailed clinical features were discussed for the patients with posterior circulation infarction in the BAH group.Results ( 1 ) The concurrent lesions included vertebral artery intracranial segment hypoplasia (n=24, VAH), fetal type posterior artery (n=18, FTPA), persistent trigeminal artery (n=1) and giant fenestration variation on vertebral artery ( n=1 ) in the BAH group.In comparison, it was more liable to cranial vascular variations in the BAH group ( P BAH group ( P<0.05).(3) these cases with stroke in two groups had no mortality during a follow-up period of 4-28 months.There were 3 cases with recurrent posterior circulation stroke in the non-BAH group.The number of cases with mRS scoring 2 points or less in the BAH group was more than that in the non-BAH group at discharge, 30 or 90 days after discharge ( P<0.05 ) .( 4 ) these cases with posterior circulation stroke in the BAH group often presented as lacunar syndrome (9/17), paramedian infarction in pons (9/17) and bilateral VAH plus unilateral FTPA (8/17).Conclusion As a relatively rare disease, BAH

    have caused damage to the social structure. Ahmet Mithat Efendi often compared the Ottomansocial life and the European one, and criticised it. This approach may be defined as the trial to let the reader appraise the right and the wrong simultaneously. Though they are fiction, Ahmet Mithat Efendi's novels are of great importance as they show the reflections of conceptions belonging to the Western civilization on Ottoman society and how the values of the Turkish society changed with the perception of the Western civilization. In this respect, particularly novels “Karnaval, Vah” and “Henüz 17 Yaşında” (Carnival, Vah and At the Age of Seventeen, where Ahmet Mithat Efendi discussed this issue were analysed in terms of the criticisms towards the Western civilization. Thereby, Ahmet Mithat Efendi's way of perception of the Western civilization and his criticisms were tried to be detected via his chosen works.

    ştirel yaklaşımlar, edebî eserlerde sıkça işlenmiştir.  İnsanın etik algısının da sorgulandığı bu tür eserlerde iktidar-birey arasındaki ilişki, sisteme dâhil olma veya sisteme karşı çıkma tercihlerini de beraberinde getirmektedir. Weber’in “bürokratik demir kafes” olarak tanımladığı ve insanın bir otomat haline dönüştürüldüğü “kaçınılmaz son”a karşı çıkan Marx; insanın sistemden uzaklaşabileceği konusunda daha iyimser bir tavır sergiler. Turgay Nar, Gizler Çarşısı adlı tiyatro metninde insanın dünyada hiyerarşik ilişkiler sarmalında iktidarın şiddet ve kontrol yöntemleriyle nasıl çürümeye uğratıldığını anlatır. Yazarın, okuyucuya/seyirciye vermek istediği mesajlar, hemen her sahnede değişse de ana tema iktidar karşısında nesneleşen insanın trajedisi olarak okunabilir. İktidar ve paranın gücü, kalabalıklar üzerinde şiddet, unutkanlık, hafıza kaybı gibi vasıtalarla denetim sağlar. Yazar, insanın iktidara geldikten sonra hemcinsi üzerinde sistematik bir baskı kurarak onu kimliksizleştirip sisteme dâhil ettiğini ironik bir tarzda bu eserinde işler. Buna göre, uygarlık, insanoğlunun cinnetini durduramamıştır; bu vahşi düzeni emziren ve kendini ona tutsak/kurban eden de insanın kendisidir. Eserde, dünyayla ilgili sorgulamanın kesildiği an insanın “körleşme ve çürüme”yle karşı karşıya kalacağı tehlikesi de dile getirilir.

Gercüş ilçesine yaklaşık 20 kilometre uzaklıktabulunan ve Dicle nehrine hakim bir noktada kurulan Deraser (Arıkmezrasında çeşitli yapı kalıntıları, kayalara oyulmuş mezarlar vemağara duvarlarına çizilmiş tarihöncesi olduğu tahmin edilen resimlerbulunmaktadır. Anadolu’da kayalara çizilmiş tarihöncesi resimlerebirçok yerde rastlanmaktadır ancak kırmızı ve siyah boyayla freskotekniğiyle yapılmış resimler nadir olarak görülmektedir. Bu nedenleDeraser’deki (Arık Berha Nivisandi (Yazılı Mağara olarak adlandırılantoprak ya da kök boyayla yapılmış kırmızı ve siyah renkli resimlerinbulunması önemli bir gelişmedir. Buradaki mağara resimlerindegenellikle evcil hayvan tasvirleri, vahşi hayvan mücadeleleri ve kadınlıerkeklişenlik sahneleri bulunmaktadır. Dünyanın pek çok yerindebulunan tarihöncesi mağara resimleri ile tematik olarak benzeşmeklebirlikte çizim tekniği bakımından özgün bir biçime sahiptir.Çalışmamızda daha önce bölgede çalışan araştırmacılar tarafındançeşitli nedenlerle farkına varılamayan Deraser (Arık mağaralardanderlenmiş resimlere ve bu resimlerle ilgili olarak yapılan araştırmasonuçlarına yer verilecektir.

    Full Text Available Objetivo: aunque se recomienda vacunar frente al virus de la hepatitis A (VHA y al virus de la hepatitis B (VHB a los pacientes con infección crónica por el virus de la hepatitis C (VHC, la estrategia de vacunación más costo-efectiva aún no está establecida. Nuestro objetivo fue comparar la vacunación universal (de todos los individuos con la selectiva (únicamente de los individuos no inmunizados frente al VHA y al VHB de los pacientes con infección crónica por VHC en nuestro medio. Pacientes y métodos: comparamos los costes directos de las dos estrategias de vacunación frente a ambos virus en 313 individuos con infección crónica por VHC. Determinamos los marcadores serológicos del VHA (anti-VHA y del VHB (HBsAg, anti-HBs y anti-HBc y tuvimos en cuenta los costes de vacunas y reactivos en nuestro ámbito. Resultados: la prevalencia de anti-VHA fue del 81,2% y la de anti-HBc del 24,6%. La prevalencia de anti-VHA aumentaba progresivamente con la edad. La inmunización frente al VHA suponía 19.806,64 € con la estrategia universal y 9.899,62 € con la selectiva. La vacunación frente al VHB ascendía a 18.780 € con la inmunización universal y a 20.385,57 € con la selectiva (mediante el anti-HBc. Se analizaron los costes considerando distintos grupos etarios y diversos factores de riesgo. Conclusiones: en nuestros individuos con infección crónica por VHC la vacunación selectiva frente al VHA es la más costoefectiva. Pero cuando el porcentaje de inmunización frente al VHA desciende por debajo del 20% la mejor opción es la universal. La diferencia en la costoefectividad de ambas estrategias de vacunación frente al VHB es pequeña, a favor de la universal, por lo que en subgrupos con elevada prevalencia de anti-HBc, como adictos a drogas y tatuados, la selectiva podría ser la mejor alternativa.Objective: although the vaccination against hepatitis A (VAH and hepatitis B (VBH is recommended in patients with HCV, the most
