    Trombidid mites have a unique lifecycle in which only the larval stage is ectoparasitic. In the superfamily Trombiculoidea (“chiggers”), the larvae feed preferentially on vertebrates, including humans. Species in the genus Leptotrombidium are vectors of a potentially fatal bacterial infection, scrub typhus, which affects 1 million people annually. Moreover, chiggers can cause pruritic dermatitis (trombiculiasis) in humans and domesticated animals. In the Trombidioidea (velvet mites), the larvae feed on other arthropods and are potential biological control agents for agricultural pests. Here, we present the first trombidid mites genomes, obtained both for a chigger, Leptotrombidium deliense, and for a velvet mite, Dinothrombium tinctorium

    Theoretical deliberation on the process of transformation of family system and how its functioning as well as data obtained in course of empirical research specify conditions of development of youth brought up in single-parent families. Picture of situation of educational development functioning of single-parent families gives theoretical knowledge on deficite of these educational environments. The most common hazards are within psychosocial factors. On the basis of obtained data and scientific theories conclusions were drawn for educational practice and requirement of work with families at the school counselor level were finally expressed. Within the framework of activities addressed to families of changed structure both work with children growing up in described environments must be included and work with single parents. Proposed activities should be of repair and support type

    Firewalls are key elements of network security infrastructure. They should guarantee the proper level of security and, at the same time, the satisfying performance in order to not increase the packet delay in the network. In the paper, we present the comparative study on performance and security of a few firewall technologies including hardware, software and virtual solutions. Three important criteria are considered: the maximal throughput of firewall, the introduced delay and the ability to resist Denial of Service attacks. We report results of experiments, present analysis and formulate a few practical conclusions

The absence of setae p3 makes <i>H. yosii</i> similar to two Nearctic species: <i>H. matura</i> (Folsom, 1916) and <i>H. utahensis</i> (Wray, 1953) (sensu Christiansen & Bellinger 1998). <i>H. matura</i> has 8 cylindrical sensilla on ant. IV and fine granules on the dens (<i>H. yosii</i>: 9–10 cylindrical sensilla on ant. IV, coarse granules on the dens) and <i>H. utahensis</i> has 3 lobes in the postantennal organ, the m-row of setae on abd. V and only 7 setae on ant.
