Placoid and polyodontode scales of stem chondrichthyans have been found in the early Lochkovian “Ditton

Group” of the Brown Clee Hill district, Shropshire, England and at Talgarth, south Wales. One of the forms is

assigned to a new species of Altholepis Karatajūtė-Talimaa, 1997, a genus already recognised from Lochkovian

shallow marine deposits in Celtiberia, Spain and the Northwest Territories, Canada as well as the type locality in

Podolia, Ukraine. Altholepis salopensis sp. nov. is based on small polyodontode scales with typically three to eight

high odontodes; the scale form was previously considered to belong to acanthodian “Nostolepis” robusta (Brotzen,

1934). The structure of other scales formerly assigned to “Nostolepis” robusta has led us to erect a new genus

Jolepis for this scale form, which differs from Altholepis in lacking an ordered layout of odontodes. Jolepis robusta

(Brotzen, 1934), originally (and possibly still) considered to be an acanthodian, is also known from the Baltic

countries, Russia, and northern Germany (ex erratic limestones). Scales of acanthodian Parexus recurvus Agassiz,

1845, and/or possibly from the stem chondrichthyan Seretolepis elegans Karatajūtė-Talimaa, 1968 (scales of these

two taxa are barely distinguishable), and of stem chondrichthyan Polymerolepis whitei Karatajūtė-Talimaa, 1968

are also present. Altholepis, Jolepis gen. nov., Seretolepis Karatajūtė-Talimaa, 1968 and Polymerolepis Karatajūtė-

Talimaa, 1968 are found in marine deposits elsewhere; the British occurrence of these taxa adds to the debate on

the sedimentological origins of the Lower Old Red Sandstone deposits in the Welsh Borderland. The geographic

range of several early sharks is now known to extend around the Old Red Sandstone continent and beyond.

Job crafting is an employees activity aimed to change and improve own work which serves to find the meaning in job. Activities related to job crafting usually occur beyond the superiors’ knowledge so the feeling of autonomy of a worker may hinder or encourage them to craft job. The study aimed to determine the correlations between organizational rank and job crafting with respect to a mediating role of autonomy and organizational tenure as a moderator. Study 1 (N = 102) showed that people having managerial positions undertake task crafting more often than non-managers. Managers and non-managers are no different with regards to cognitive and relational crafting. Autonomy mediated the relationship between organizational rank and task crafting. Most of the results in study 2 (N = 99) was a replication of the results of study 1. The differences are probably related to a various length of organizational tenure for a current organization. The results of the presented studies indicate the role of autonomy in undertaking job crafting, what is being discussed in the literature worldwide and Polish studies.

Questioning in class is often found by students to be highly stressful and a cause of anxiety. Lower-order questions, in particular, are often closely linked to behaviour management, with teachers using them as a means of control in the classroom while e.g. manipulating or accusing. The fact that questions are mainly initiated by teachers ( they ask up to two questions every minute and questioning may account for even up to a third of all teaching time) and that there exists a strong asymmetric relationship in their number (students, on average ask not more than 6 questions during one lesson) may have a tremendous impact on students’ emotional well-being and their learning. This asymmetric relationship stems from differences of status, roles, age, education or class and can give teachers power or authority. Questions are commonly used as part of a power struggle, and pupils can still fi nd this sort of interrogation intimidating. Thus teacher’s questioning (Mitchell cited in Hastings 2003) has been found children’s main source of fear and face-threatening act – the learners are not afraid of being wrong, but of looking silly – saying something that will be ridiculed by the teacher or other pupils. It is well known that FTAs threatening the hearer’s self-image include expressions negatively evaluating the hearer’s positive face, e.g. disapproval, accusations, disagreement or criticism and all of these elements are commonly appearing in teacher’s discourse and questions they ask. Those of the lower status and less dominant role (students) use more indirectness and more negative politeness features, such as hedges and mitigation, than those with the higher status (teachers) do (Cutting 2002). The article also aims at presenting Bloom’s taxonomy of cognitive learning (1956) and the influence the language of teacher’s questions may have on students experiencing face-threatening acts.

Interest in growing roses in Poland is related to the production of cut flowers as ornamentals and of petals and hips for cosmetics or food products. However, recently there has been an increasing number of reports of pest damage on rose plantations. In the case of fruits the damage has been attributed to flies (Rhagoletis alternata) or moths (Cydia tenebrosana), while nematodes have been implicated for growth reduction even on plantations grown under soil-less conditions. Field trials and laboratory experiments to test the possibility of controlling R. alternata larvae or pupae with entomopathogenic fungi and nematodes resulted in a lack of parasitism. On the other hand, the use of Bacillus thuringiensis subsp. kurstaki or Cydia pomonella granulovirus effectively controlled C. tenebrosana. Meloidogyne incognita infestation of roses growing on rock wool substrate was drastically reduced by Arthrobothrys oligospora or abamectin. Factors such as the method of product application or pest susceptibility to the used microbial-based products accounted for the observed differences in efficacy.

Different anchoring groups such as thiophene-2-acetic and malonic acid were investigated for synthesis of new photosensitizers. The new dyes (photosensitizers) were made pure and determined by various analytical techniques. The chemical structure of synthesized materials was certified by analytical studies. UV-Visible and fluorescence spectra revealed intense fluorescence and absorption for organic photosensitizers. The cyclic voltammetry results showed that the two photosensitizers were suitable for dye sensitized solar cell preparation. The work electrode was gathered using tin (IV) oxide nanoparticles in dye-sensitized solar cells structure. The new photosensitizers and tin (IV) oxide were used for photovoltaic devices preparation. The power conversion efficiency was obtained as about 4.12 and 4.29% for Dye 1 and Dye 2, respectively.

Tereny pogórnicze, powstałe w wyniku odkrywkowej eksploatacji surowców mineralnych, budzą coraz większe zainteresowanie jako przestrzeń, która wprawdzie została mocno przekształcona, ale obok pewnej przyrodniczej degradacji wykazuje również specyficzne, nowe korzystne właściwości. Wraz z odkrywaniem tych walorów i przemianami społecznymi zmienia się również nastawienie do obszarów zdegradowanych i ich ponownego zagospodarowania. Wyraża się to w coraz bardziej kreatywnym podejściu do tego zagadnienia, widocznym w liczbie kierunków rekultywacji, proponowanych przez literaturę przedmiotu i akty prawne. Wyrobiska powstałe w wyniku wydobycia surowców skalnych stanowią niekiedy bardzo sprzyjające środowisko dla rozwoju wielu gatunków roślin i zwierząt, nierzadko chronionych. Odsłonięcia przekrojów geologicznych w ścianach tych wyrobisk dają możliwość tworzenia stanowisk z cennymi poznawczo i edukacyjnie strukturami geologicznymi. Niemniej cenne, a niejednokrotnie przewyższające wartości przyrodnicze, są zasoby kulturowe związane z dawnym wykorzystaniem surowców naturalnych. Do przykładów takiej działalności zalicza się, chyba nie zawsze doceniane przez badaczy krajobrazu i przeszłości, wydobycie i wykorzystanie wapieni, głównie jako materiału kamiennego i do produkcji wapna. Z diagnozowanie (niejednokrotnie wręcz wykrycie) walorów kulturowych reliktów tej działalności wymaga prowadzenia badań wykorzystujących wiadomości i metody z różnych dyscyplin naukowych i technicznych, a ich wyniki mają potencjał wzbogacający wiedzę w wielu dziedzinach, niejednokrotnie odległych od stricte górniczego fachu. Niniejszy artykuł ma na celu pokazanie bogactwa poznawczego i utylitarnego obiektów pozostałych po zakończeniu eksploatacji górniczej oraz przydatności ich badań o interdyscyplinarnym charakterze, na przykładach związanych z przemysłem wapienniczym.

The cotton aphid, Aphis gossypii is an economically significant insect pest infesting various important crops and vegetables. The neonicotinoid, acetamiprid was recommended against aphids with excellent results. Resistance emergence and environmental pollution makes acetamiprid a favorable alternative to conventional insecticides. The aims of the present work were to predict acetamiprid resistance risk in A. gossypii, investigate cross resistance to other tested insecticides and explore acetamiprid stability in the absence of selection. A field-collected population from Sharqia governorate, Egypt was selected with acetamiprid. After 16 generations of selection, there was a 22.55-fold increase in LC50 and the realized heritability (h2) of resistance was 0.17. Projected rates of resistance indicated that, if h2 = 0.17 and 50% of the population was killed at each generation, then a tenfold increase in LC50 would be expected in 12.2 generations. If h2 was 0.27 then 7.63 generations would be needed to achieve the same level. In contrast, with h2 of 0.07 it necessitates about 30 generations of selection to reach the same level. Cross resistance studies exhibited that the selected strain showed obvious cross resistance to the other tested neonicotinoid members, moderate cross resistance to alpha-cypermethrin and no cross resistance to pymetrozine. Fortunately, resistance to acetamiprid in the cotton aphid was unstable and resistance reverses the nearby susceptible strain throughout five generations without exposure to acetamiprid. Our results exhibited cotton aphid potential to develop resistance to acetamiprid under continuous selection pressure. The instability of acetamiprid makes A. gossypii amenable to resistance management tactics such as rotation with pymetrozine.

A new method measuring of mass in electronic system of scales has been described. The main element of this system is inductive measuring load cell, which was compared with strain gauge load cell. The aim of the paper is described advantages of the inductive measuring system of mass and explain some main problems of this system. Digital correction of the mechanical errors of the beam like: hysteresis, creep material of the beam under constant load, influence of ambient temperature was described.

In this paper we present the numerical simulation-based design of a new microfluidic device concept for electrophoretic mobility and (relative) concentration measurements of dilute mixtures. The device enables stationary focusing points for each species, where the locally applied pressure driven flow (PDF) counter balances the species’ electrokinetic velocity. The axial location of the focusing point, along with the PDF flowrate and applied electric field reveals the electrokinetic mobility of each species. Simultaneous measurement of the electroosmotic mobility of an electrically neutral specie can be utilized to calculate the electrophoretic mobility of charged species. The proposed device utilizes constant sample feeding, and results in time-steady measurements. Hence, the results are independent of the initial sample distribution and flow dynamics. In addition, the results are insensitive to the species diffusion for large Peclet number flows (Pe > 400), enabling relative concentration measurement of each specie in the dilute mixture.

The use of canticles in liturgical monody goes back to the early Middle Ages when the practice of canonical hours began to be used extensively. The canticles of the Gospel (Benedictus, Magnificat and Nunc dimittis) were successively incorpora- ted into the structure of the canonical hours and became in time the most important chants of the Liturgy of the Hours (Laudes, Vesperae, Completorium).

Some shorter canticles of the Old Testament books were also included in the Divine Office but it was only after the Second Vatican Council that shorter canticles of the New Testament books came into Vespers. They replaced the final (i.e. the third) psalm.

The designation „song" which was used to describe „canticle" in the Polish translation of the revised Liturgy of the Hours appeared to be highly controversial and inadequate. Thus, it was necessery to explain such definitions as: canticle, psalm, hymn, song. Based on the studies it is possible to definitely determine that a return to the original designation (canticle) is necessary and inevitable, in order to avoid confusion in terminology. Benedictus and Magnificat have received the primary thrust of poetic translations of canticles into Polish. In the latter case there are as many as five different Magnificat translations in Polish church song-books; only two versions of the Benedictus have been found. These canticles have a wide liturgical application; their use is not limited to the Divine Office alone.

They have been introduced into the Roman Catholic Order of Mass as the chants after Communion, or as the responsorial psalms, or as the verses sung before Gospel. Some of them have become independent processional chants for Mass, especially the ones intended for Lent. As far as the number of musical settings is concerned, it can be said that the Magnificat canticle seems to be highly favored. Nevertheless the melodies connected to other canticles, including the ones with the texts from „non-Gospel" biblical books, deserve attention as well. The melodies originated either in the Gregorian chant, or in the ecclesiastical songs, or in foreign sources, or, finally, in indigenous pieces of original compositions.

Thus, the repertoire of the New Testament canticles exhibits itself as a rich resource of new chants which have been included in the official liturgy in Poland since the Second Vatican Council. Clearly, further research is required in the aera.

The article describes a test stand with a spindle equipped with an active bearing preload system using piezoelectric actuators. The proper functioning of the spindle and the active system was associated with the correct alignment of the spindle shaft and the drive motor. The article presents two methods of shaft alignment. The use of commonly known shaft alignment methods with dial indicators is insufficient from the viewpoint of being able to control this preload. This work aims at making the readers aware that, for systems with active bearing preload, the latest measuring devices should be used to align the shaft. The use of commonly known methods of equalization with dial gauges is insufficient from the point of view of controlling this preload. Increasing the accuracy of shaft alignment from 0.1 to 0.01 mm made it possible to obtain a 50% reduction in the displacement of the outer bearing ring during spindle operation.

The paper presents a numerical study of an aircraft wheel impacting on a flexible landing surface. The proposed 3D model simulates the behaviour of flexible runway pavement during the landing phase. This model was implemented in a finite element code in order to investigate the impact of repeated cycles of loads on pavement response.

In the model, a multi-layer pavement structure was considered. In addition, the asphalt layer (HMA) was assumed to follow a viscoelastoplastic behaviour.

The results demonstrate the capability of the model in predicting the permanent deformation distribution in the asphalt layer.
