A new quill mite species Syringophilopsis davidi sp. nov. (Prostigmata, Syringophilidae) parasitizing Greater Short-toed Lark Calandrella brachydactyla (Leisler) (Passeriformes, Alaudidae) in Egypt is described. This new species is distinguishable from S. tyranni Bochkov and Galloway by 10-13 chambers of the peritremal lateral branches, setae se located slightly anterior to c1, and by setae ag2 about twice longer than the genital setae. This is the first record of this genus from the hosts of the family Alaudidae and in the Arab Republic of Egypt.

This study was conceived to detect skin mites in social mammals through real-time qPCR, and to estimate taxonomic Demodex and further Prostigmata mite relationships in different host species by comparing sequences from two genes: mitochondrial 16S rRNA and nuclear 18S rRNA. We determined the mite prevalence in the hair follicles of marmots (13%) and bats (17%). The high prevalence found in marmots and bats by sampling only one site on the body may indicate that mites are common inhabitants of their skin. Since we found three different mites (Neuchelacheles sp, Myobia sp and Penthaleus sp) in three bat species (Miotis yumanensis, Miotis californicus and Corynorhinus townsendii) and two different mites (both inferred to be members of the Prostigmata order) in one marmot species (Marmota flaviventris), we tentatively concluded that these skin mites 1) cannot be assigned to the same genus based only on a common host, and 2) seem to evolve according to the specific habitat and/or specific hair and sebaceous gland of the mammalian host. Moreover, two M. yumanensis bats harbored identical Neuchelacheles mites, indicating the possibility of interspecific cross-infection within a colony. However, some skin mites species are less restricted by host species than previously thought. Specifically, Demodex canis seems to be more transmissible across species than other skin mites. D. canis have been found mostly in dogs but also in cats and captive bats. In addition, we report the first case of D. canis infestation in a domestic ferret (Mustela putorius). All these mammalian hosts are related to human activities, and D. canis evolution may be a consequence of this relationship. The monophyletic Demodex clade showing closely related dog and human Demodex sequences also supports this likely hypothesis.

The quill mite fauna of the family Syringophilidae (Acari: Prostigmata: Cheyletoidea) associated with owls (Aves: Strigiformes) is reviewed. A new genus is proposed, Neobubophilus Skoracki & Unsoeld gen. nov. It differs from closely related Bubophilus (Bubophilus Philips and Norton, 1978) by the absence of leg setae vsII in the both sexes. In addition, four new species are described: (1) Neobubophilus cunicularius Skoracki & Unsoeld sp. nov. from Athene cunicularia (Molina, 1782) (Strigidae) from Paraguay; (2) Neobubophilus atheneus Skoracki & Unsoeld sp. nov. from Athene noctua (Scopoli, 1769) and Athene brama (Temminck, 1821) (Strigidae), both from India; (3) Bubophilus tytonus Skoracki & Unsoeld sp. nov. from Tyto alba affinis (Blyth, 1862) (Tytonidae) from Cameroon, and (4) Megasyringophilus dalmas Skoracki & Unsoeld sp. nov. from Megascops choliba (Vieillot, 1817) (Strigidae) from Venezuela. The following new host species are given: Bubo bubo (Linnaeus, 1758) (Strigidae) from Nepal for Bubophilus ascalaphus (Philips and Norton 1978) and Strix woodfordii (Smith, 1834) (Strigidae) from Tanzania for Bubophilus aluconis (aluconis Nattress and Skoracki 2009).

With nearly 6000 named species, water mites (Hydrachnidiae) represent the largest group of arachnids to have invaded and extensively diversified in freshwater habitats. Water mites together with three other lineages (the terrestrial Erythraiae and Trombidiae, and aquatic Stygothrombiae), make up the hyporder Parasitengonina, which is characterized by having parasitic larvae and predatory nymphs and adults. Relationships between the Hydrachnidiae and other members of the Parasitengonina are unclear, as are relationships among the major lineages of water mites. Monophyly of water mites has been asserted, with the possible exception of the morphologically distinctive Hydrovolzioidea. Here we infer the phylogeny of water mites using multiple molecular markers and including representatives of all superfamilies of Hydrachnidiae and of almost all other Parasitengonina. Our results support a monophyletic Parasitengonina including Trombidiae, Stygothrombiae, and Hydrachnidiae. A monophyletic Hydrachnidiae, including Hydrovolzioidea, is strongly supported. Terrestrial Parasitengonina do not form a monophyletic sister group to water mites. Stygothrombiae is close to water mites but is not nested within this clade. Water mites appear to be derived from ancestors close to Stygothrombiae or the erythraoid group Calyptostomatoidea; however, this relationship is not clear because of extremely short branches in this part of the parasitengonine tree. We recovered with strong support all commonly accepted water mite superfamilies except for Hydryphantoidea, which is clearly paraphyletic. Our data support the previously proposed clades Protohydrachnidia (Hydrovolzioidea and Eylaoidea), Euhydrachnidia (all remaining superfamilies), and the euhydrachnid subclade Neohydrachnidia (Lebertioidea, Hydrachnoidea, Hygrobatoidea, and Arrenuroidea). We found that larval leg structure and locomotory behavior are strongly congruent with the molecular phylogeny. Other morphological and behavioral characters, including host choice, are not as strongly correlated with phylogeny. Molecular dating suggests that the Hydrachnidiae arose about 235MYA, and that Neohydrachnidia began to diversify about 155MYA. Our results provide a strong framework for classification and for further elaboration at finer taxonomic scales, which will allow testing of ecological and behavioral hypotheses associated with the transition from terrestrial to aquatic life.

The superfamily Eriophyoidea is exceptionally diverse and its members are highly host-specific. Currently, the taxonomy of this group is based on morphology only. However, phylogenetic relationships in this group could be incorrect if the diagnostic morphological characters are homoplastic. Therefore, the phylogeny of 112 representative taxa of Eriophyoidea from China was determined using 18S, 28S D2-5 and D9-10 rRNA. Phylogenetic relationships were inferred through Bayesian, maximum likelihood and maximum parsimony methods, and then a number of clades or major clades were defined according to robust phylogenetic topologies combined with morphological comparison. Tests of monophyly showed that two of three families of Eriophyoidea as well as one subfamily and four tribes were not monophyletic. Ancestral character state reconstruction (ACSR) showed that five diagnostic morphological characters evolved several times, confounding the current taxonomy. Additionally, reconstruction of the history of host plant colonization suggested host switching occurred in a limited range of host plants. The host association data made it possible to determine taxonomic relationships more accurately. These results show that by integrating morphological and molecular information and host plant choice, it is possible to obtain a more accurate taxonomy and a deeper phylogenetic understanding of Eriophyoidea.

Acariformes is the most species-rich and morphologically diverse radiation of chelicerate arthropods, known from the oldest terrestrial ecosystems. It is also a key lineage in understanding the evolution of this group, with the most vexing question whether mites, or Acari (Parasitiformes and Acariformes) is monophyletic. Previous molecular studies recovered Acari either as monophyletic or non-monophyletic, albeit with a limited taxon sampling. Similarly, relationships between basal acariform groups (include little-known, deep-soil 'endeostigmatan' mites) and major lineages of Acariformes (Sarcoptiformes, Prostigmata) are virtually unknown. We infer phylogeny of chelicerate arthropods, using a large and representative dataset, comprising all main in- and outgroups (228 taxa). Basal diversity of Acariformes is particularly well sampled. With this dataset, we conduct a series of phylogenetically explicit tests of chelicerate and acariform relationships and present a phylogenetic framework for internal relationships of acariform mites. Our molecular data strongly support a diphyletic Acari, with Acariformes as the sister group to Solifugae (PP =1.0; BP = 100), the so called Poecilophysidea. Among Acariformes, some representatives of the basal group Endeostigmata (mainly deep-soil mites) were recovered as sister-groups to the remaining Acariformes (i. e., Trombidiformes + and most of Sarcoptiformes). Desmonomatan oribatid mites (soil and litter mites) were recovered as the monophyletic sister group of Astigmata (e. g., stored product mites, house dust mites, mange mites, feather and fur mites). Trombidiformes (Sphaerolichida + Prostigmata) is strongly supported (PP =1.0; BP = 98-100). Labidostommatina was inferred as the basal lineage of Prostigmata. Eleutherengona (e. g., spider mites) and Parasitengona (e. g., chiggers, fresh water mites) were recovered as monophyletic. By contrast, Eupodina (e. g., snout mites and relatives) was not. Marine mites (Halacaridae) were
Full Text Available Introduction: The spider mite, Oligonychus afrasiaticus feeds by sucking the sap from the immature fruits tissue. The natural color of fruits changes to pale yellow or gray by mite's feeding. Damaged fruit are cracked and its damage can dry out the fruits. Because of resistance to pesticides, resurgence of date palm spider mite causes to disrupt the natural balance of their population. Tiny black ladybird beetle, Stethorous gilvifrons is the most important and active lady beetle species in Khuzestan province and is very effective on biological control of the spider mite. Determination of the amount and release time of the lady beetles are the most important factors in the implementation of biological control programs of date palm spider mite. So, careful monitoring, time of the release and the ability of deployment of predatory ladybird are essential steps to success in the programs of biological control. Materials and Methods: This research was conducted in Shadegan region of Khuzestan province. The nested design was used to compare the efficiency of different inoculate release methods of the predator, S. gilvifrons. The main niches include three release times which were at the time of emergence, three days and one week after emergence of date palm spider mite in date palm plantation. Sub nesting including three different levels of predator release including minimum, moderate and maximum release with 0.5, 1 and 3 predator /m2 per day and were continued for two weeks. The two or three-days ladybirds were used to release. First, the infected clusters were covered by mesh fabric and ladybirds were released under them. After a week, mantles were opened up to the establishment of ladybird run on the normal condition of date palm plantations. This experiment was repeated three times, and each replication consists of a quarter- hectare plantation with dominant cultivar Sayer.Three date Palm trees from each release and control were randomly selected. One hundred fruits from10 major's of each bunches were randomly selected and the number of spider mite (prey and coccinellid (predator were counted in different developmental stages. The relationship between predator and prey was calculated by using Pearson's correlation in different treatments as an index of density-dependent reaction of the predator to prey density and its establishment. Results and Discussion: Results showed that there were significant difference between treatments of release on seasonal mite and lady beetle populations and the average seasonal growth reduction rate at 1% probability level. The maximum difference in the number of mite – infested treatment and control occurred at maximum release with predatory mite. The maximum density of the lady beetle population was observed around mid to late June. Date palm fruits were been at Kharg phonological growth at this time and they had the greatest sensitivity to the mite population. The highest correlation coefficient occurred in terms of release time coincided with the moderate and maximum release of spider mite´s predator. So, the predator showed density - depend reaction and its establishment were occurred. Release of three and one lady beetle/m2 and simultaneously with the appearance of spider mite had powerful and significant correlation. In those circumstances, the density-dependent response of lady beetle was observed. The prey and the predator population densities have several fluctuations around their equilibrium level during the season. Number of predator population declines and prey population increases from their equilibrium levels were reduced by the simultaneous release of the predator to start prey activities. The predatory failure establishment is zero in the maximum release.The highest control of date palm spider mite was about 83.28% at release treatments. In all releasing treatments, the level of biological control was increased with increasing the number of coccinelid releases per unit. Conclusions: The highest predator efficiency were calculated in the maximum release (3 coccinellid per square meter and simultaneously with the appearance of spider mite in date palm plantation. The control performance was 83.27 percent in this condition. Understanding of the fluctuations of the date palm pests and their natural enemies and the effect of climatic factors on the fluctuations are necessary to operate the proposed models for biological date palm pest control. The success of this predator is high in terms of the date ecosystem, and the susceptibility of palm fruit to pests decreased at the end of the season.

Infection rate, reaction to light, and hair follicle apoptosis are examined in the dogmite, Demodex canis Leydig (Prostigmata: Demodicidae), in dogs from the northern area of Taiwan. An analysis of relevant samples revealed 7.2% (73/1013) prevalence of D. canis infection. Infection during the investigation peaked each winter, with an average prevalence of 12.5% (32/255). The infection rates significantly varied in accordance with month, sex, age, and breed (p canis Bodin (Onygenales: Arthrodermataceae) and Trichophyton mentagrophyte Robin (Blanchard) on the D. canis infected dogs revealed prevalence rates of 4.4% (2/45) and 2.2% (1/45), respectively. Observations demonstrated that D. canis slowly moved from a light area to a dark area. Skin samples were examined for cellular apoptosis by activated caspase3 immunohistochemical staining. Cells that surrounded the infected hair follicles were activated caspase3-positive, revealing cell apoptosis in infected follicles via the activation of caspase3.

In this work, we compare morphological and molecular data in their ability to distinguish between species of water mites (Acari, Prostigmata, Hydrachnidia). We have focused on the two species of the genus Lebertia inhabiting the island of Madeira. While traditional morphological traits were initially sufficient to distinguish between these two species, the molecular data were more dependable on the kind of analysis carried out. Single arbitrary genetic distance (e.g. a K2P distance below 2%) may lead to the conclusion that the specimens under study belong to the same species. Analysing the same specimens with the coalescent model has proved the evolutionary independence of both Lebertia clades in Madeira. Furthermore, multi-rate Poisson Tree Process analysis confirmed both lineages as independent species. Our results agree with previous studies warning of the dangers of rigid species delimitation based on arbitrary molecular distances. In addition, the importance of different molecular data approaches for correct species delimitation in water mites is highlighted.

Studies on the seasonal variation of agricultural pest species are important for the establishment of integrated pest control programs. The seasonality of pest attacks on crops is affected by biotic and abiotic factors, for example, climate and natural enemies. Besides that, characteristics of the host plant, crop management, location and the pests' bioecology also affect this seasonality. The mites Polyphagotarsonemus latus (Prostigmata: Tarsonemidae) and Tetranychus bastosi (Prostigmata: Tetranychidae) are the most important pests in the cultivation of physic nut, Jatropha curcas (Euphorbiaceae). All parts of J. curcas can be used for a wide range of purposes. In addition many researchers have studied its potential for use as neat oil, as transesterified oil (biodiesel), or as a blend with diesel. However studies about physic nut pests have been little known. The objective of this study was to assess the seasonal variation of P. latus and T. bastosi in physic nut. This study was conducted at three sites in the state of Tocantins, Brazil. We monitored climatic elements and the densities of the two mite species and of their natural enemies for a period of 2 years. Attack by P. latus occurred during rainy seasons, when the photoperiod was short and the physic nut had new leaves. In contrast, attack by T. bastosi occurred during warmer seasons with longer photoperiods and stronger winds. Populations of both mites and their natural enemies were greater in sites with greater plant diversity adjacent to the plantations. The predators found in association with P. latus and T. bastosi were Euseius concordis (Acari: Phytoseiidae), spiders, Stethorus sp. (Coleoptera: Coccinellidae) and Chrysoperla sp. (Neuroptera: Chrysopidae).

The economic importance of the palm Bactris gasipaes is growing in the Neotropoical region. We collected leaflets from plants under a chemical fertilization regime and a population of 5000 plants per hectare, in Costa Rica. The variety, Diamantes 10, has an ascendency fom the upper Amazon basin. We used Harries hematoxiline, eocine and standard light microscopy techniques. The presence of raphids and buliform cells was confirmed for the abaxial surface of the leaflets and for the hypodermic tissue on both sides. The absence of the Krantz anatomy was confirmed in consistence with former observations about the C3 photosynthesis in other species of Palmaceae. The average stomatal density on the abaxial surface was 96.87 +/- 16.31 stomata.mm(-2) and 14.20 +/- 4.05 in the adaxial surface.

A total of 125 individuals caught with mist nets were examined alive; a total of 22 parasites were found dead and were exposed to parasit autopsy. The extracted parasites were preserved in 70% alcohol for subsequent mounting and identification. Ectoparasites were found in 56 black-chinned siskins (38%; 48 of them (33% had 870 mites – 680 feather mites (Astigmata: Analgoidea were identified as Proctophyllodes spini, 167 as Knemidokoptes jamaicensis, 19 as Strelkoviacarus critesi, and one as Analges passerinus. Moreover, three mites were chiggers belonging to the tribe Schoengastiini (Prostigmata: Trombiculidae. In 21 birds (14%, 54 lice were found, 21 of which were identified as Philopterus roehreri, 18 as Myrsidea serini, and 15 as Ricinus carolynae. Endoparasites were not found in the necropsied individuals. All of the parasites that were found represent new records for Chile, and they also serve as new records of host–parasite associations for S. barbatus.

DDT, radiolabeled with /sup 36/Cl (total activity of 10.2 mc) and applied in the field at the rate of 1.12 kg/ha, cannot be detected within decomposer microarthropods using liquid scintillation spectrometry. Soil microarthropods exhibit both positive and negative responses to direct and indirect effects of DDT. Faunal simplification (decreased diversity) resulting from pesticide application as reported by many others does not apply to the oribatid and prostigmatid mites of the old field. New colonization is possible by some species of Acari as a result of DDT application. Soil microbial respiration is enhanced by a single DDT application of 1 kg/ha. No apparent relationships exist between the increased microbial respiration and soil microarthropod population dynamics in this DDT treated old field. No apparent relationships exist between soil pH, moisture levels, texture and soil microarthropod population dynamics. Microarthropod community structure (species diversity and richness, interspecific relationships and similarity) are definitely affected by a single application of DDT. The Prostigmata are the most numerous mites in the soil of an old field in central Ohio. Vertebrate predators feeding on terrestrial snails may be subjected to magnified concentrations of DDT residues. Coprophagic decomposer organisms feeding on snail feces will be subject to much larger DDT concentrations. Terrestrial snails represented by Cepaea and Otala are not killed by acute oral doses of DDT. Within a three year period after a single application of DDT no effects on the soil faunal populations were seen below 3 cm of soil.

Participants and methods: A cross-sectional study was conducted involving physicians and newly diagnosed breast cancer patients from three public/teaching hospitals in Malaysia. The Control Preference Scale (CPS was administered to patients and physicians, and the Krantz Health Opinion Survey (KHOS was completed by the patients alone. Binary logistic regression was used to determine the association between sociodemographic characteristics, the patients’ involvement in treatment decision-making, and patients’ preference for behavioral involvement and information related to their disease. Results: The majority of patients preferred to share decision-making with their physicians (47.5%, while the second largest group preferred being passive (42.6% and a small number preferred being active (9.8%. However, the physicians perceived that the majority of patients preferred active decision-making (56.9%, followed by those who desired shared decision-making (32.8%, and those who preferred passive decision-making (10.3%. The overall concordance was 26.5% (54 of 204 patient–physician dyads.

Over 40 species of aquatic angiosperms, including submersed, floating and emergent types, have been examined for photosynthetic status as part of a search for possible aquatic C/sub 4/ species. The C/sub 4/ system is viewed as potentially of adaptive value in certain aquatic situations, although evidence for its occurrence there is not conclusive. Emphasis was on plants from North-temperate softwater and hardwater lakes to explore both possibilities of CO/sub 2/ limitation, i.e., low total inorganic carbon in softwater vs. low free CO/sub 2/ in hardwater lakes. On the basis of leaf cross-section anatomy, all plants examined, with one exception, clearly did not show evidence of C/sub 4/ ''Krantz anatomy.'' In the submersed plant Potamogeton praelongus Wulf, large starch-producing chloroplasts were concentrated in cells surrounding vascular bundles and in a narrow band of cells between vascular bundles. The in situ photosynthetic rate of this plant was twice that of a related species, but other evidence including PEP carboxylase content and photorespiratory response to high O/sub 2/ did not confirm the presence of the C/sub 4/ photosynthesis.

The study was aimed at determining the dynamics of the emotional state and factors influencing thereupon in patients presenting with atherosclerosis of lower limb arteries and undergoing surgical treatment. The study included a total of sixty-five 36-to-90-year-old patients (53 men and 12 women) subjected to examination twice - prior to surgery and before discharge by means of semi-structured interview, self-assessment scale of feeling and mood, methods "Integrative test of anxiety" and "Type of attitude towards the disease" (TOBOL), questionnaire for assessing health-related quality of life SF-36 and Krantz questionnaire in order to determine the position in the therapeutic process. After surgery (on postoperative day 7-10 of hospital stay) the patients demonstrated a decrease in the degree of anxiety and somatic complaints. Women (p=0.037), patients with the duration of the disease from 1 to 8 years (p=0.033), with signs of personality anxiety (p≤0.045), disadaptive variants of attitude to disease and treatment (p≤0.05), as well as clearly manifesting mistrust for medical recommendations (p=0.014) belong to a group of risk of emotional stress at the postoperative stage. Clinical and socio-demographic determinants are comparatively less important in formation of pronounced anxiety of postoperative period than the patient's personality.

The ability to separate particles based on their size has wide ranging applications from the industrial to the medical. Currently, cyclonic separators are primarily used in agriculture and manufacturing to syphon out contaminates or products from an air supply. This has led us to believe that cyclonic separation has more applications than the agricultural and industrial. Using the OpenFoam computational package, we were able to determine the flow parameters of a vortex in a cyclonic separator in order to segregate dust particles to a cutoff size of tens of nanometers. To test the model, we constructed an experiment to separate a test dust of various sized particles. We filled a chamber with Arizona test dust and utilized an acoustic suspension technique to segregate particles finer than a coarse cutoff size and introduce them into the cyclonic separation apparatus where they were further separated via a vortex following our computational model. The size of the particles separated from this experiment will be used to further refine our model.

Full Text Available Longstanding observations suggest that dissolved materials are lost from fresh litter through leaching, but the role of soil fauna in controlling this process has been poorly documented. In this study, a litterbag experiment employing litterbags with different mesh sizes (3 mm to permit soil fauna access and 0.04 mm to exclude fauna access was conducted in three habitats (arid valley, ecotone and subalpine forest with changes in climate and vegetation types to evaluate the effects of soil fauna on the concentrations of dissolved organic carbon (DOC and total dissolved nitrogen (TDN during the first year of decomposition. The results showed that the individual density and community abundance of soil fauna greatly varied among these habitats, but Prostigmata, Isotomidae and Oribatida were the dominant soil invertebrates. At the end of the experiment, the mass remaining of foliar litter ranged from 58% for shrub litter to 77% for birch litter, and the DOC and TDN concentrations decreased to 54%–85% and increased to 34%–269%, respectively, when soil fauna were not present. The effects of soil fauna on the concentrations of both DOC and TDN in foliar litter were greater in the subalpine forest (wetter but colder during the winter and in the arid valley (warmer but drier during the growing season, and this effect was positively correlated with water content. Moreover, the effects of fauna on DOC and TDN concentrations were greater for high-quality litter and were related to the C/N ratio. These results suggest that water, rather than temperature, dominates how fauna affect the release of dissolved substances from fresh litter.
Full Text Available Stress urinary incontinence (SUI has a significant impact on the quality of life for many women. Most women do not seek medical attention for this condition. Treatment for this problem includes initial conservative therapies and then surgery is an option. More than 200 surgical procedures have been described in the literature for the treatment of stress incontinence. The gold-standard surgical treatment of SUI in patients with a mobile bladder neck and normally functioning urethra has been accomplished through a retropubic approach using either a Burch or Marshall-Marchetti-Krantz procedure. By the absolute success of Trans obturator tape (TOT application in treatment of SUI and the niche it has created for itself in the maze of treatment modalities available for SUI, there seems to be little doubt that TOT is all set to become the new Gold Standard for treatment of SUI in times to come. It is difficult to imagine any further improvements in the midurethral sling procedures or surgeries for SUI. However 10 years ago, no one could have imagined the progress and development that has been seen over these few short years in the treatment of SUI. The future may hold promise in technologies such as stem cells that may be injected in or around the urethral support structures and provide regeneration of the lacking support structures. What so ever, it′s definitely time to provide millions of women with knowledge that empowers them to make lifestyle changes to decrease their risk of SUI and to understand the reality that they are not alone if they have SUI.

Dessa forma, o objetivo desse trabalho foi realizar o levantamento da população de ácaros associados às plantas ornamentais no município de Arapiraca-AL, em função dos diversos problemas acarretados por essa espécie. O levantamento foi realizado entre os meses de abril a março, através de amostragens mensais de folhas coletadas da parte basal, intermediária e apical de plantas existentes em praças e jardins. Foram coletados 55 ácaros pertencentes à ordem Prostigmata em 20 famílias de plantas. As plantas com as maiores riquezas de ácaros foram as Coleus blumei L. e Bxuxus sempervirens L., que apresentaram 65% dos valores amostrais. Analisando-se as coletas realizadas, pode-se observar que houve uma maior incidência populacional de ácaros na coleta do mês de maio, cuja percentagem foi de 36% de ácaros levantados, sendo que no levantamento dos dados amostrais de março a percentagem encontrada foi de 14%, nas amostragens dos meses de abril e junho, a percentagem amostrada dos dados foi de 22 e 28%, respectivamente. O estudo do levantamento de ácaros em plantas ornamentais permitiu observar a relação entre ácaros e a relação com a planta hospedeira, facilitando posteriormente um estudo mais aprofundado sobre plantas hospedeiras, e pode-se observar que em períodos chuvosos ocorre uma menor incidência populacional.
Wherever mankind travels in space, people will always be preceded by unmanned probes that will provide the first bit of information. But there comes a time when we've learned all we can by unmanned vehicles. Man comes on the scene and makes the decisions about what is most valuable to us here, and that makes space into a new laboratory. Photography plays a vital role in all that John Glenn, in 'The View from Space'. Why do you take a photograph? We took a lot of documentation pictures because we were supposed to. But a lot of photographs were taken on instinct things you can't predict you're going to see or that are going to impress you. You say, 'Now I've got to take a picture of that" or "Look at the way that is positioned' or' Look at the way the sun is shining on that." Those 'stand-back' pictures were taken with aesthetics in mind, to capture and document the venture itself." Eugene Cernan in 'The View from Space'. The Apollo mode for a Science Support Room in Mission Control will not work for Mars. The time delay makes it nearly useless. Our team was available for instantaneous reaction and assistance to the crew on EVA. Therefore the Science Support Team has to be on Mars! The crew that went out the day before will do the supporting. They will hand off to each other for the next EVA. They will send a daily report back to Earth as to what was accomplished, problems that need resolution, supporting video, data, etc. etc. In Apollo, that was the role of my "Tiger Team," who sat in Gene Krantz' office watching and listening but having no role for directly helping the Back Room. They wrote a summary of the EVA, what was accomplished, what got omitted that was important to insert into the next EVA. It was distributed throughout Mission Control- especially to the Big Brass, Flight Director, and the CapCom.

In addition, it examines perceptions of consequences of violence, their adverse health effects, and how women resist violence within marital life.Methods: Five focus group discussions were conducted with 28 women in Karachi. Purposive sampling, aiming for variety in age, employment status, education, and socioeconomic status, was employed. The focus group discussions were conducted in Urdu and translated into English. Manifest and latent content analysis were applied.Results: One major theme emerged during the analysis, ie, family violence through the eyes of females. This theme was subdivided into three main categories. The first category, ie, situations provoking violence and their manifestations, elaborates on circumstances that provoke violence and situations that sustain violence. The second category, ie, actions and reactions to exposure to violence, describes consequences of ongoing violence within the family, including those that result in suicidal thoughts and actions. The final category, ie, resisting violence, describes how violence is avoided through women’s awareness and actions.Conclusion: The current study highlights how female victims of abuse are trapped in a society where violence from a partner and family members is viewed as acceptable, where divorce is unavailable to the majority, and where

Full Text Available Ideen über land und bewohner žemaitens aus der paläokomparativismus-zeitZusammenfassungDie traditionelle Erklärung des Namens Žemaitens (vgl. žemas ist wahrscheinlich die älteste (obwohl nicht die einzige, vgl. žemė Etymologie der litauischen Sprache. Sie war schon in einem Brief Vytautas des Großen aus dem 15. Jh. belegt. Seit dieser Zeit ist diese Erklärung des Toponyms sowohl in Litauen als auch anderswo in Osteuropa weit verbreitet. Erst später (vgl. das vielmals ausgegebene und übersetzte Werk Abraham Ortelius, Teatri Orbis Terrarum, 1570 wurde sie gleichfalls in westeuropäischen Umlauf gesetzt. Da noch lange Zeit Žemaiten in Westeuropa terra incognita blieb, ist es weiterhin interessant die ersten Erwähnungen des Toponyms und des Etnonyms in Westeuropa zu untersuchen. In der Epoche des linguistischen Paläokomparativismus der Renaissance-Zeit (15. -16. Jh. gab es in Westeuropa auch eine andere Meinung über die eigentlichen Einwohner Žemaitens. Nach Auffassung von Aeneas Sylvius Piccolomini wurden die Maʃʃagetae gerade zwischen Livonien und Preußen in den Werken mehrerer Autoren (z.B. Volaterranus, Hartmann Schedel, Johann Cochlaeus gesetzt. Eine kritische Stellung gegen diese Meinung nahmen damals nur einzelne andere Autoren (wie z. B. Jan Stobnica, Albert Krantz ein. In dem Beitrag wird untersucht 1 wie und vor allem mit welchen Argumenten über dieses Thema während des ganzen Jahrhunderts diskutiert wurde; 2 auf welche Art und Weise eine Verwechslung zwischen Samagetae und Maʃʃagetae entstehen konnte. Zu dem letzten Punkt werden zwei nicht alternative, sondern sich integrierende Hypothesen vorgeschlagen, und zwar mittels: a einer Volksetymologie, b einer obscura per obscuriora explicalio. Es wird endlich gezeigt, wie eine solche Unklarheit bei dem Namen der Žemaiten auch bei anderen Autoren der Renaissance-Zeit (wie z. B. Angelo Rocca zu unerwarteten Verwechslungen führte (vgl.

Population-based data on IPV from Muslim societies are scarce, and Pakistan is no exception. This study was conducted among women residing in urban Karachi, to estimate the prevalence and frequency of different forms of IPV and their associations with sociodemographic factors.Methods: This cross-sectional community-based study was conducted using a structured questionnaire developed by the World Health Organisation for research on violence. Community midwives conducted face-to-face interviews with 759 married women aged 25–60 years.Results: Self-reported past-year and lifetime prevalence of physical violence was 56.3 and 57.6%, respectively; the corresponding figures for sexual violence were 53.4% and 54.5%, and for psychological abuse were 81.8% and 83.6%. Violent incidents were mostly reported to have occurred on more than three occasions during the lifetime. Risk factors for physical violence related mainly to the husband, his low educational attainment, unskilled worker status, and five or more family members living in one household. For sexual violence, the risk factors were the respondent’s low educational attainment, low socioeconomic status of the family, and five or more family members in one household. For psychological violence, the risk factors were the husband being an unskilled worker and low
Preference for information is a personality trait that affects people's tendency to seek information in health-related situations. Prior studies have focused primarily on investigating its impact on patient-provider communication and on the implications for designing information interventions that prepare patients for medical procedures. Few studies have examined its impact on general consumers' interactions with Web-based search engines for health information or the implications for designing more effective health information search systems. This study intends to fill this gap by investigating the impact of preference for information on the search behavior of general consumers seeking health information, their perceptions of search tasks (representing information needs), and user experience with search systems. Forty general consumers who had previously searched for health information online participated in the study in our usability lab. Preference for information was measured using Miller's Monitor-Blunter Style Scale (MBSS) and the Krantz Health Opinion Survey-Information Scale (KHOS-I). Each participant completed four simulated health information search tasks: two look-up (fact-finding) and two exploratory. Their behaviors while interacting with the search systems were automatically logged and ratings of their perceptions of tasks and user experience with the systems were collected using Likert-scale questionnaires. The MBSS showed low reliability with the participants (Monitoring subscale: Cronbach alpha=.53; Blunting subscale: Cronbach alpha=.35). Thus, no further analyses were performed based on the scale. KHOS-I had sufficient reliability (Cronbach alpha=.77). Participants were classified into low- and high-preference groups based on their KHOS-I scores. The high-preference group submitted significantly shorter queries when completing the look-up tasks (P=.02).

Lignite (organic rich) and calcified lignite (inorganic rich) samples from excavation field -50c mining area Pesje, Velenje Basin, Slovenia were investigated. During geological and structural mapping lignite and calcified lignite samples were systematically taken for determination of their petrological, geochemical and isotopic characteristics. Lignite is composed of fine detritical gelified matrix. At least five different types of calcified lignite were recognized forming laminations, calcifications after wood, petrified wood and complete replacements of lignite with carbonate. All measured parameters so far indicate geochemical processes during sedimentation of the Velenej Basin. After macroscopic description samples were split to organic and inorganic component (Ward, 1984) and powdered in an agate mortar for geochemical and isotopic analyses. Major and trace elements (As, B, Ba, Cd, Co, Cr, Cu, Hg, Mn, Mo, Sb, Se, Th, U, Zn) in these samples were determined by instrumental neutron activation analysis (INAA) using k-0 standardization method (Jaćimović et al, 2002). The isotopic composition of carbon and nitrogen was determined using a Europa 20-20 continuous flow IRMS ANCA-SL preparation module. A 1 mg amount of a sample was weighed in a tin capsule for carbon and 10 mg for nitrogen analysis. Samples for carbon analyses were pretreated with 1 M HCl to remove carbonates. Carbonate samples from carbonate-rich strata and calcified xylite were first roasted at 450 deg C (Krantz et al., 1987). Three miligrams of carbonate sample was transformed into CO2 by reaction with anhydrous H3PO4 at 55 deg C under vacuum (McCrea, 1950) and measured with GV 2003 isotope ratio mass spectrometer. Measured isotopic composition of oxygen as VPDB values was recalculated to the VSMOW reference standard to enable the comparison with data from other coal basins. SEM/EDXS of carbonate rich sediments was performed with JEOL JSM 5800 electron microanalyzer scanning electron microscope
