scholarly journals The protobranchiate mollusca; a functional interpretation of their structure and evolution

Examination of the structure of species of Nucula , Leda , Yoldia and Solenomya led Pelseneer (1891), in his classic work on the morphology of the Lamellibranchia, to establish for their inclusion the order Protobranchia. He regarded them as in almost all respects a primitive group, and Stempell (1898 a, 1898 b, 1899) came to very similar conclusions. Later (1898, 1911) Pelseneer extended his work on these animals, grouping all recent species in the three families Solenomyidae, Nuculidae and Ledidae ( = Nuculanidae). On the other hand, Neumayr (1891), on the basis of the hinge characters, grouped all but the first of these families with the Arcidae, Glycymeridae and Limopsidae in the order Taxodonta. Thiele (1934) elaborated this classification, dividing the Taxodonta into two divisions, Nuculacea and Arcacea, and subdividing the former into the four families Nuculidae, M alletiidae, Ledidae ( = Nuculanidae) and Solenomyidae. Finally, Douville (1912), in his illuminating sketch of a possible classification of the Lamellibranchia, regarded the Nuculidae and the Nuculanidae as affording some indication of the original characters of those Lamellibranchia which took to a more or less active life on the sea bottom, and the Solenomyidae as representing to some extent ancestral conditions to those which assumed life in burrows. Douville’s views have been well summarized by Davies (1933, I935).* Verrill and Bush (1897, 1898) have given the best account of the shell characters of the Protobranchia, while knowledge of m any aspects of their morphology has recently been extended by Heath (1937).

Although St. Basil did not live 50 years, the topic of the old age appears in his works quite often. On the other hand, it is clear that Basil does not discuss this issue in one par­ticular work or in the longer argumentation. The fragmentary statements about old age can be found in almost all his works, but most of them can be found in the correspondence of Basil. In this paper we present the most important ad the most interesting aspect of teach­ing of Basil the Great. As these certificates show that the bishop of Caesarea looked at the old age maturely, rationally estimated passage of time, which very often makes a man different. He experienced it, for example as a spiritual and physical suffering, which often were connected with his person. He saw a lot of aspect of the old age, especially its advan­tages – spiritual maturity and wisdom. What is more, he pointed also to passage of time, which leads a man to eternity, which should be prepared to, regardless how old he is. In his opinion fear is not seen opinions of St. Basil present really Christian way of thinking, well-balanced and calm.

This research is aimed at studying the Hunto Sultan Amay Mosque located in Gorontalo City. Hunto Sultan Amay Mosque is the oldest mosque in the city of Gorontalo The Hunto Sultan Amay Mosque was built as proof of Sultan Amay's love for a daughter and is a representation of Islam in Gorontalo. Researchers will investigate the visual form of the Hunto Sultan Amay Mosque which was originally like an ancient mosque in the archipelago. can be seen from the shape of the roof which initially used an overlapping roof and then converted into a dome as well as mosques in the world, we can be sure the Hunto Sultan Amay Mosque uses a dome roof after the arrival of Dutch Colonial. The researcher used a qualitative method by observing the existing form in detail from the building of the mosque with an aesthetic approach, reviewing objects and selecting the selected ornament giving a classification of the shapes, so that the section became a reference for the author as research material. Based on the analysis of this thesis, the form  of the Hunto Sultan Amay mosque as well as the mosques located in the archipelago and the existence of ornaments in the Hunto Sultan Amay Mosque as a decorative structure support the grandeur of a mosque. On the other hand, Hunto Mosque ornaments reveal a teaching. The form of a teaching is manifested in the form of motives and does not depict living beings in a realist or naturalist manner. the decorative forms of the Hunto Sultan Sultan Mosque in general tend to lead to a form of flora, geometric ornaments, and ornament of calligraphy dominated by the distinctive colors of Islam, namely gold, white, red, yellow and green.

Since the remarkable paper by Professor Lapworth “On an Improved Classification of the Rhabdophora” was published in the Geological Magazine for 1873, a great deal of fresh information has been gathered as to these interesting fossils; but the classification given in that paper, though to some extent confessedly artificial, is still generally adhered to. Observations made by the authors in recent years lead them to suppose that that classification will in the future undergo considerable modification; but in the present state of our knowledge it serves a purpose so useful, that it is not our intention to propose any immediate change in it. Our object, on the other hand, is to bring forward certain conclusions which we have independently reached, and which will, we believe, enhance the value of Graptolites to the stratigraphical geologist, and lead to results important to the biologist. Our conclusions are based upon an examination of a large number of forms generally referred to the family Dichograptidæ; but, as we propose very briefly to indicate, they affect the relationships of Graptolites belonging to other families also.

An attempt was made to test if Lourinia armata (Claus, 1866)—as it is currently diagnosed—represents a species complex. Detailed examination and comparisons of several specimens collected from different localities suggest that L. armata indeed represents a complex of four closely related morphospecies that can be differentiated from one another by only detailed observations. One of the four species is identified as Lourinia aff. armata and the other three species are described as new to science and named as Lourinia wellsi sp. nov., L. gocmeni sp. nov., and L. aldabraensis sp. nov. Detailed review of previous species records indicates that the genus Lourinia Wilson, 1924 is distributed worldwide. Ceyloniella nicobarica Sewell, 1940, originally described from Nicobar Island and previously considered a junior subjective synonym of L. armata is reinstated as Lourinia nicobarica (Sewell, 1940) comb. nov. on the basis of the unique paddle-shaped caudal ramus seta V. It is postulated that almost all of these records are unreliable in terms of representing true Lourinia aff. armata described herein. On the other hand, the comparative evaluation of the illustrations and descriptions in the published literature indicates the presence of several new species waiting to be discovered in the genus Lourinia.                 It has been determined that, according to updated modern keys, the recent inclusion of the monotypic genus Archeolourinia Corgosinho & Schizas, 2013 in the Louriniidae is not justified since Archeolourinia shermani Corgosinho & Schizas, 2013 does not belong to this family but should be assigned to the Canthocamptidae. On the other hand, it has been argued that the exact phylogenetic position of the Louriniidae still remains problematic since none of the diagnostic characters supports the monophyly of the family within the Oligoarthra. It has also been argued that the close relationship between Louriniidae and Canthocamptidae is supported since both families share the homologous sexual dimorphism (apophysis) on P3 endopod. The most important characteristic that can possibly be used to define Louriniidae is the reduction of maxilliped.

Vocabulary known as an essential skill for learning to read, speak, write and listen. It is important to find the appropriate technique in order to improve students’ vocabulary mastery. The researchers did research with focuses on students’ perception towards using “dictionary pocket” in order to improve their vocabulary mastery. It was conducted using a qualitative descriptive method. To collect the data, the researchers use the instruments of an open-ended questionnaire and interview section. The samples were 36 students of second grade from Broadcasting major at SMK Negeri 1 Cimahi. The result of the questionnaire shows that it was found that almost all of the students feel that with learn vocabulary can be easier when they use the technique of remembering dictionary pocket. They also agree that dictionary pocket is an appropriate technique which is used to learn vocabulary. In the other hand, the result of interview shows, the students concede that they are feel helped and being motivated. It can be sum up that dictionary pocket is suitable to strengthen their vocabulary mastery. Dictionary pocket is useful enough because it can help them when they forget the word.

Abstract In this article we give a brief summary of how Norwegian and Polish sentences are classified in the widely acknowledged grammar books. Therefore, we review the definitions of sentences in both languages, and compare the various classifications applied in Norwegian and Polish. Additionally, much focus is given to classification of sub clauses, which happen to be differently characterized in the respective languages. We would claim that there is a significant bias regarding features that determine classification of sub clauses in Norwegian and Polish. While in Norwegian a lot of emphasis is put on structural features, focusing on how particular units are organized within a sentence, the Polish classifications seem more semantic-oriented. As far as grammatical terms are concerned, Norwegian is featured by far more notions that might yield intransparency for a Polish learner or grammarian. On the other hand, the Norwegian classifications seem far more transparent. Due to a lack of 1-1 relation between terms used in Norwegian and Polish, we cater for this need by providing terms applicable for both languages. We believe that this may come into useful for all who try to systematize their knowledge about sentences in both languages.

Over the years, scholars have sought to provide language-based typologies of names, but while attempts have been made for some sub-branches of onomastics such as anthroponymy and toponymy, there is arguably none for ecclesionymy (the study of church names). Consequently, this paper sought to provide a language based typology of the hitherto underexplored area of church names. Data of names of churches in Ghana was built for the present study. Adopting content analysis as the analytical approach, the study realized that church names in Ghana are generally homogenous and heterogeneous linguistically. It was also realized that homogenous/unilingual church names involved English only, Akan only and Ewe only. On the other hand, the heterogeneous church names comprised two types: bilingual and trilingual church names, which contained varied language permutations from the three spheres in Osei Yaw Akoto’s classification of languages in Ghana. The paper concludes by making some recommendations for language-in-religion policy in Ghana. Keywords: Church names, Ecclesionymy, Glocal language, Unilingual

This article examines the problems of classification of toponymy of the Uzbek people in the research conducted in the 60s of the XX century to the beginning of the XXI century and the role of ethnotoponyms as a separate classification unit. We know that toponyms also include place names formed based on the names of people, nation, tribe, ethnic group, tribe. The field of scientific and practical study of these names is called ethnotoponymy. Ethnotoponyms, on the other hand, are the name of an ethnos, that is, they are the result of the interaction of an ethnonym and a system of toponyms. In this regard, the study of ethnotoponyms as a separate form of classification unit is extremely relevant

The theory of cognitive dissonance is one of the recently developed tools that marketing has borrowed from the behavioral sciences to investigate consumer behavior. The classification of goods into convenience, shopping, and specialty categories, on the other hand, is among the most venerable ideas in marketing literature. This article merges the two by using the theory of cognitive dissonance to give a new dimension to the classification of consumer goods. The result is a fresh set of behavioral criteria for classifying goods.

SummaryUnder the name of “Progenesis” (from the prefix “pro “, in front, and of the Greek “genesis “, generation) a new conception and classification of the factors of development were proposed by R. Turpin, the progenesis grouping “the whole of the hereditary and non hereditary factors that preexist to the fecundation and that concur to the formation of the being and to its development”.This conception has the advantage of designating indifferently, to all progenitic factor, hereditary as well as non hereditary, a place marked in advance; it has the advantage of showing beside the paternal maternal factors, the characteristic progenetical factors of the couple; it has the advantage to draw the attention on factors which were before neglected (age of mother, age of father, rank of birth, sex of the preceding pregnancy, interval between pregnancies, number of pregnancies, etc.) and whose importance increases in proportion as the gathering of the facts is abundant enough to lend itself to the statistical analyses; it has lastly the advantage of leading to an etiological prevention of the congenital defects, trying to draw the most advantage from the surrounding factors, without discarding, when they are imposed by the circumstances, the possibilities brought to their right proportion of the eugenic selection.To illustrate this progenesic conception of the ontogenesis a simple example, the gemellity, deserves to be retained.If we consider the gemellity as a deviation in regard to the simple pregnancies, it constitutes at the same time the more frequent and the best registered of anomalies. It lends itself to the study of its relations with divers progenesic factors which the authors regard by turns with the complement of their personal researches : age of the progenitors, rank of the pregnancy, sex of the product of the anterior last conception.If on the other hand, we consider the gemellity itself as a progenesic factor, we can study on the development, and for instance, which the authors have done, on the rate of masculinity. This study has lead them to put in value the phenomenon of diminution of the masculinity in relation to the degree of the multiplicity of pregnancy.
