Butterfly is one of the amazing creatures of nature, which possesses some interesting behavior like puddling that includes feeding at mud, dung or carrion. A total of 54 species of butterflies under 8 families were found to gather around two different puddle grounds viz. Jahangirnagar University campus (JU campus) and bank of Bangshi river (BBR), Savar, Dhaka during January 2012 to December 2013. Among the recorded 54 species of butterflies, 6 species belonged to the family Papilionidae, 11 species to Pieridae, 10 species to Lycaenidae, 3 species to Danaidae, 13 species to Nymphalidae, 7 species to Satyridae, 3 species to Hesperiidae and 1 species to Acraeidae. In JU campus several types of puddling sources were used by butterflies viz. mud or wet soil, dung, carrion, wet sands and wet bricks, human sweat, bird-dropping, rotten fruits and flowers. On the other hand, in the bank of Bangshi river, butterflies used polluted water on the river side. In those puddle sources, members of Papilionidae and Pieridae were preferred mineral sources as they did puddle on mostly water sources (mud, wet soil, wet sand, wet brick), while members of Nymphalidae, Hesperiidae and Lycaenidae preferred to puddle on various nutrient sources (carrion, dung, rotten flowers). These results indicated that butterfly require various minerals and nutrients which are extracted through puddling sources for their reproductive success and other physiological activities.Jahangirnagar University J.

Abstract In the paper we present the selected properties of composition relation of the convergent and divergent permutations connected with commutation. We note that a permutation on ℕ is called the convergent permutation if for each convergent series ∑an of real terms, the p-rearranged series ∑ap(n) is also convergent. All the other permutations on ℕ are called the divergent permutations. We have proven, among others, that, for many permutations p on ℕ, the family of divergent permutations q on ℕ commuting with p possesses cardinality of the continuum. For example, the permutations p on ℕ having finite order possess this property. On the other hand, an example of a convergent permutation which commutes only with some convergent permutations is also presented.

Organizations are these days realizing the importance of women in the workforce and to tap that talent, organizations are now-a-days putting extra efforts. Workplaces were designed keeping men in mind and which has been intercepting women from continuing the competitive jobs and career along with the family responsibilities. On the other hand, there are various workplace barriers which are adding to the other problems. Women face several barriers at the workplace like sexual harassment, glass ceiling and gender stereotype.

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.

We have investigated growth of ectomycorrhizal (ECM) fungi (i.e., 55 strains of 32 species in 15 genera) on saturated (palmitate), monounsaturated (oleate), diunsaturated (linoleate), triunsaturated (linolenate) fatty acids, and the triacylglyceride of oleate (triolein) lipid to elucidate an ability to utilize the fatty acids and lipid as a carbon source for growth. Relative utilization ratios (URs, %) based on mycelial growth on glucose suggest that ECM fungi belonging to the family Thelephoraceae have an ability to utilize palmitate. On the other hand, ECM fungi in the genus Laccaria can utilize at least either palmitate or oleate. Furthermore, Hygropharus russula grows on palmitate, oleate, and slightly on triolein. Lactarius chrysorrheus grows only on palmitate. These fatty-acid- and lipid-utilizing fungi may be promising as model fungi for further elucidation of the metabolic ability to utilize the fatty acids and lipid as a carbon source. On the contrary, the fungi in the genus Suillus were shown to scarcely utilize the fatty acids and lipid. Furthermore, most ECM fungi did not grow on either linoleate or linolenate.Key words: carbon source, ectomycorrhizal fungi, fatty acid, lipid, mycelial growth.

Abstract Sharing a corridor space in a rusunawa could form patterns of adaptation and exemplify the phenomenon of territorial mastery. This research aims to understand the form of this mastery as perceived by the occupants using the Grounded Theory method. The results show a theory of territorial mastery that can be developed from the findings in the field is a new theory of territorial characteristics, based on hard and soft territory. The hard territory is territorial control that is tangible or intangible, fixed or unchanged, and firm, whose existence is clear in a space that can be seen, occupied or controlled and maintained, and recognized by other residents. On the other hand, the soft territory is territorial control that is tangible and intangible, and which allows for flexible and soft shifts because it is an expression of the family and cultural emotions of guyub, so that mastery of the soft territory occurs not only because of tolerance, but also because of the prioritization of the feeling of kinship in living under one roof, and the harmonization of guyub relationships amongst people in a community

Every family member has different needs from one another. Children are the most important members of the family, especially in completing their needs. Each child has different basic needs. In the case of gender, sometimes boys are often prioritized over girls. But on the other hand girls also have many needs related to their nature as women. This various cases cause different need compliance that requires parents’ consideration. Therefore, parents need to accommodate their children needs which have gender diversity. In managing these children's needs, parents' creativity and understanding of their children are needed.

This chapter sets out the ways in which the family might be thought to pose problems for the liberal framework, and defends the adoption of that framework from the objection that it simply cannot do justice to—or, perhaps, fails adequately to care about—the ethically significant phenomena attending parent–child relationships. On the one hand, liberalism takes individuals to be the fundamental objects of moral concern, and the rights it claims people have are primarily rights of individuals over their own lives: the core liberal idea is that it is important for individuals to exercise their own judgment about how they are to live. On the other hand, parental rights are rights over others, they are rights over others who have no realistic exit option, and they are rights over others whose capacity to make their own judgments about how they are to live their lives is no less important than that of the adults raising them.

While La Croix du Maine and Sainte-Marthe were responding in part to representations of family—as underpinning literature and learning—that they found in some of the works they surveyed, on the other hand the pair were also extending the family function further still. The vast fields of high-cultural endeavour scoped by La Croix du Maine and Sainte-Marthe did not simply pre-exist their surveys but were further shaped by them. Both surveys were highly selective in social, gender, regional, and other terms. Sainte-Marthe’s Elogia perhaps communicate more profoundly than any other work in the period the triangular imbrication of (i) family, (ii) social hierarchy, and (iii) literature and learning.

It is well known that proper names in the East, and especially among the Mohammadans, follow no such simple rule as that which has long prevailed in modern Europe, where the Christian name or names conferred in infancy and the family name or surnames are usually borne through life, and where it is a matter of suspicion to have an alias. In the East, on the other hand, we hear of persons gathering up in the course of their career a variety of names, and being popularly known by one or other of them at different periods, and to an extent that gives rise to perplexity. This was notably the case among the Arabs in the height of their preeminence. A person might receive a name in his infancy (usually conferred on his birth or at his circumcision), and to this might be added a patronymic, or a name expressive of his paternal or family relations. He might then receive a title expressive of his zeal for the faith, and soubriquets descriptive of his personal qualities or appearance, or the country or town in which he was born or had settled, or the religious sect to which he belonged ; and if he played a part in public life, to all these might be added, as in Europe, a title or titles of dignity; and if he had acquired a reputation as an author, he might assume some name of fancy. These various names or titles might never be united in the same individual, but the combinations are numerous and shifting. Certain rules are observed in their formation or application, but it was a matter of accident by which of these designations a person might be known to his contemporaries, or his name transmitted to modern times.
