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 The aim of the present study was to determine and compare the fatty acids, lipid soluble vitamins, sterols, phenolics, and antioxidant capacities of three endemic Salvia L. taxa (S. euphratica var. Montbret & Aucher ex Bentham leiocalycina (Rech. Fil.) Hedge, S. euphratica var. Montbret & Aucher ex Bentham euphratica (Rech. Fil.) Hedge and S. pseudoeuphratica Rech.Fil.) and to evaluate these results systematically. The fatty acid compositions were determined by using gas chromatography, while the lipid soluble vitamins, sterols, and phenolics were determined by using HPLC. Also, the antioxidant capacities of three Salvia taxa were measured in vitro. Palmitic acid was found as major saturated fatty acid while oleic acid, linoleic acid, α-linolenic acid, and erucic acid were found as major unsaturated fatty acids in the present study. It was found that S. euphratica var. euphratica had lower palmitic acid (8.94 ± 0.71%), total saturated fatty acid (19.16 ± 0.15%), and higher unsaturated fatty acid content (82.08 ± 0.52%) than other studied taxa. Furthermore, it was shown that S. euphratica var. euphratica had different 18.3/18:2 (0.36) unsaturated/saturated fatty acid (4.28) ratios. However, this study demonstrated that Salvia taxa had low lipid soluble vitamins, sterol contents. On the other hand, it was shown that Salvia taxa had similar catechin (509.2 ± 4.21 µg/g and 552.2 ± 9.21 µg/g) and vanillic acid amounts (351.2 ± 2.17 µg/g and 396.8 ± 4.1 µg/g) in this study. And also, it was found that Salvia taxa had high rosmarinic acid content while S. euphratica var. leiocalycina had the highest rosmarinic acid content (1480 ± 7.57 µg/g). On the other hand, it was shown that the two ferulic acid contents of S. euphratica varieties were higher (1175 ±/5.21 µgmg-1740.2 ± 4.82 µg/mg) than the ferulic acid content of S. pseudoeuphratica of which was the lowest (19.2 ± 0.97 µg/mg). The present results suggested that the biochemical results guided the morphological studies, and Salvia taxa have a potent antioxidant capacity.

Fatty Acid Compositions

Seed oils of 18 species of Aceraceae (maple family) were examined and their fatty acid compositions were determined. Those of all but one species had substantial amounts of C20, C22, and C24cis-monoenoic acids. Acer rubrum, typical of the group, had 7% eicosenoic, 13% docosenoic, and 4% tetracosenoic acid in the total fatty acids of its oil. The chief isomers, identified in the oil of A. saccharum, were cis-11-eicosenoic, cis-13-docosenoic, and cis-15-tetracosenoic acids. The oils of Dipteronia sinensis and Acer negundo were much like the other Acer oils in composition, but that of A. saccharinum was composed almost entirely of the ordinary C16 and C18 fatty acids. The results are discussed in relation to the taxonomy of the family.

The Continuum

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.

Abstract Objectives The objectives of this study were to determine the effect of 2’fucosyllactose (2’FL) and fat blends on growth, body composition and fatty acid profile of the liver and brain using the neonatal pig as a model for the human infant. Methods Pigs (3 d old) were randomly assigned to either: 1. control, 2. Palm Olein (PO) fat blend – Low 2'-FL, 3. PO – High 2'-FL, 4. High oleic acid (HO) – Low 2'-FL, 5. HO FB – High 2'-FL, 6. PO FB – GLA, or 7. kept with their sows. Pigs in groups 1 to 6 received 250 ml·kg−1·d−1 of formula in 5 equal meals for 15 d. On day 14 of the study, groups 1–6 received intraperitoneal E. coli LPS challenge at 100 µg·kg−1 weight. Results Body weight was greater for piglets fed by sows than those in the other groups (P < 0.001). In addition, % fat and bone mineral content were higher in the sow-fed group while lean % was less sow-fed piglets (group 7) compared with those in the other groups (P < 0.05). Only longissimus weight expressed as a % of body weight, was greater for group 7 compared with all other groups (P < 0.001). Soleus, semitendinosus, brain, heart and spleen weights as a % of body weight were similar across all groups. However, liver weight as a % of body weight was greater in groups 1–6 (3.7%) compared with group 7 (2.8%; P < 0.001). The proportion of brain 16:1 fatty acid was less (0.83%) for groups 1–6 than for group 7 pigs (1.08%; P < 0.0001). The proportion of 20:3 N6 was greatest (0.66%) for group 3 compared with groups 1 and 4 (0.55%; P < 0.05). In addition, the proportion of 20:5 N3 was greatest (0.12%) for group 3 compared with groups 1 and 7 (0.07%; P < 0.05). The proportion of liver 16:1, 18:0, and 18:1 cis-11 fatty acids were greater for group 7 (2.3, 23, 2.2%) than groups 1–6 (0.2, 20, 1.2%; P < 0.0001). Conversely, the contribution of 14:0, 18:1 cis-9, 18:3 N6 cis-6,9,12, and 22:6 N3 were greater for pigs in groups 1–6 (1.3, 0.6, and 14, 7.8%) compared with those in group 7 (0.5, 8.5, 0.2 and 3.5%; P < 0.0001). Conclusions Our data suggest that feeding 2’fucosyllactose had no effect on the body weight gain and composition in neonatal pigs. Our data also suggest that dietary fatty acids have a greater effect on liver than on brain fatty acid composition. Funding Sources Funding for the work was provided by Perrigo Nutritionals, LLC.

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.

Territorial Control

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

The levels of fatty acids, phospholipids and sterols were determined in the brains of she-goat and castrated goat found in Ekiti State, Nigeria by gas chromatography. Results showed that the crude fat levels were 9.98 and 10.2 % in the brains of she-goat and castrated goat respectively. The fatty acid composition of she-goat and castrated goat brain shows that the SFA was 40.6 and 42.7 %, MUFA was 37.1 and 38.7 % and PUFA was 20.9 and 22.3% respectively. The other parameters of she-goat and castrated goat brain were found: PUFA/SFA, 0.490 and 0.548; MUFA/SFA, 0.869 and 0.953; n-6/n-3, 0.775 and 11.7; LA/ALA, 0.876 and 28.0; AA/DGLA, 6.05 and 17.4; EPA/DHA, 1.00 and 5.89 and EPSI (PUFA/MUFA), 0.564 and 0.575 respectively. Phospholipids were present in she-goat and castrated goat with a value range of 2365 and 3047 mg/100g respectively. Among the sterols, only cholesterol was of any significant level with values of 1353 mg/100g (she-goat brain) and 1355 mg/100g (castrated goat brain). Linear correlation at ? = 0.05, df: n-1 showed that no significant difference exists between the crude fats, phospholipids and sterols except in the fatty acids parameters.Bangladesh J. Sci. Ind.

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.
