Synthesis, crystallographic data, solubility and electrokinetic properties of copper-, nickel- and cobalt˗uranylphosphate

Une discussion est consacree a la transformation en milieu acide de curite en phosphate d'uranyle de cuivre, de nickel et de cobalt. A partir d'analyses chimiques, thermodifferentielles et thermogravimetriques, les formules cristallo-chimiques calculees sont Cu (UO₂/PO₄)₂ • 8 H₂O, Ni (UO₂/PO₄)₂ • 7 H₂O et Co (UO₂/PO₄)₂ • 7 H₂O. Les deux derniers produits cristallisent dans le systeme triclinique, groupe spatial P1 ou P[-1]. Les parametres de la maille valent : a = 6,975 A ; b = 6,938 A ; c = 10,700 A ; α = 106,2° ; β = 104,8° ; γ = 90,3° pour Ni (UO₂/PO₄)₂ • 7 H₂O et a = 7,007 A ; b = 6,981 A ; c = 9,105 A ; α = 102,6° ; β = 106,1° ; γ = 90,4° pour Co (UO₂/PO₄)₂ • 7 H₂Ο. Cu (UO₂/PO₄)₂ • 8 H₂O cristallise dans le systeme quadratique, groupe spatial P4/nmm et les parametres de la maille valent : a = b = 6,969 A et c = 17,306 A. D'apres les mesures de la solubilite, les produits de solubilite ont ete calcules comme : 10exp[-12,8], 10exp[-9,5] et 10exp[-9,9] respectivement pour les phosphates d'uranyl de cuivre, de nickel et de cobalt. Les proprietes electrocinetiques de ces trois produits ressemblent a celles de la metatorbernite naturelle : le potentiel zeta est negatif et le point de charge electrique nul ne peut pas etre atteint dans l'intervalle de pH de 2 a 9.

Two genes with fertile attributes from Macrobrachium nipponense (De Haan, 1849) (Natantia: Palaemonidae): evidence from expression analysis of Mago nashi and Tsunagi proteins during oocyte maturation and embryonic development

Mago nashi (Mago) and Tsunagi (Y14) are the core components of the exon junction complex that play important roles in RNA metabolism and development of eukaryotic organisms. We identified two cDNAs encoding Mago and Tsunagi protein from the oriental river prawn Macrobrachium nipponense (De Haan, 1849) and termed MnMago and MnTsu , respectively. The MnMago cDNAs encoded a 147-amino-acid protein with an obvious “Mago nashi” domain. The MnTsu cDNA encoded a 161-amino-acid protein with a conserved RNA recognition motif. Prediction of interaction modeling showed that Mago and Tsunagi proteins formed a Mago-Tsunagi dimer complex, indicating that the two genes may play a biological function through the Mago-Tsunagi protein complex in M. nipponense . Real-time quantitative PCR analyses showed that the expressions of MnMago and MnTsu in the ovary were consistent among developmental stages. The expression gradually increased from perinucleolus- to oil-globule stage, and reached the peak at the secondary vitellogenesis stage. After a sharp decrease at oocyte maturation stage, the expressions bounced back at the paracmasis stage. The expression patterns of the two transcripts were also synchronized with embryonic development. The highest expression appeared at the protozoea stage, suggesting that MnMago and MnTsu play an important role in the process of embryogenesis. The Mago and Tsunagi cDNA sequences were sequenced from the oriental river prawn for the first time and the pattern of gene expressions was described during oocyte maturation and embryonic development. This study indicates that these two genes in the embryo and ovary perform important roles in reproductive physiology in the oriental river prawn.
Effect of Thermal and Mechanical History on the Creep Rate of Inconel 617

A study was made of the effects of thermal aging and stress change on the creep rate of Inconel 617 at temperatures above 900°C. It was found that the creep curve sensitively varied with thermal aging prior to the creep test. At 900°C and under higher stresses thermal aging increased the creep rate of both the transient and steady stages. With decreasing the stress at 900°C or increasing the test temperature the steady state creep rate became insensitive to thermal history. The irregular (nonclassical) creep curve possibly due to dYl/amic strain aging was shown to alter its shape kv thermal aging to the classical typr, using four different heats of Inconel 617. Prestraining under higher stress was f ound to influence the creep rate in the subsequent creep test under lower stress. Following the stress reduc tion the creep rate initially decelerated and then asymptotically approached to the value obtained without prestraining. From a practical view point, a distinguished feature was that the illjluence of stress drop on the creep rate has become obscure with decreasing the amount of prestrain to the practical strain range less than 0. 1 %.
Molecular variations in the diamond back moth, Plutella xylostella (l.) (hyponomeutidae: lepidoptera) as inferred from mitochondrial and ribosomal markers

The diamondback moth, Plutella xylostella (L.) (Hyponomeutidae: Lepidoptera) is a serious pest of crucifers worldwide. Understanding genetic difference among various populations would reveal the prevalence of strains or biotypes or cryptic species. The mitochondrial (COX-1) and nuclear (ITS1) marker to understand genetic differences in P. xylostella were analysed. Analysis based on mitochondrial gene (658 bp) revealed presence of two genetic groups with 14 polymorphic sites. Its1 had 12 nucleotide deletions. Our study revealed that P. xylostella is not a homogenous population and further studies are underway.
Genetic Variability Studies in Segregating Populations of Upland Cotton Involving Exotic Parents (Gossypium hirsutum L.)

The research work comprising of genetic variability, heritability and genetic advance studies for seed cotton yield and its components in two segregating F2 generations of non-Bt cotton (Gossypium hirsutum L.) was carried out during 2012–13 at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, India. Each cross had an exotic line as one parent. Genetic potential of segregating F2 generations for different parameters revealed that plant height varied from 34 cm to 125 cm, bolls plant per plantfrom 1 to 31 and seed cotton yield perplant from 2g to 72g, across the two populations. High broad sense heritability and genetic gain were recorded for these traits suggesting that rigorous plant selection can be practised to identify desirable plants from these two F2 populations.
The Teaching of Mathematics.

It is very important that mathematics students, from the junior-senior level on, develop the habit of critically examining all details, stated and unstated, of any argument they are considering. Many working mathematicians (myself included) are somewhat lax in this, at least with respect to published arguments. After all, if the author states that such-and-such is the case, and the assertion seems plausible, it is probably correct, so why bother with the grubby details? While I can more or less get by with such carelessness, students cannot. For example, the most common textbook arguments [1], [2], [4], [5], [7], [12] for the arcwise connectedness theorem of elementary point set topology all contain the same glaring error. Any student reading one of these "proofs" should notice that almost the simplest possible examples of the construction used (for example, the illustrations given in [4]) serve to refute the argument. Of course, this was overlooked by the authors of at least six textbooks, but they are all working mathematicians and don't have to be as careful as students. The error, though not subtle, seems to have considerable appeal and it might be well to put it to rest now, lest it becomes established as fact by induction, or through the Method of Infinite Repetition. I propose, therefore, to describe the argument, point out the flaw, and suggest ways of correcting it. The theorem and its proof are simple enough to be understood by anyone having even a rudimentary knowledge of topology. A compact, connected metric space is called a continuum, and a continuum in which each point has arbitrarily small connected open neighborhoods is said to be locally connected. An arc is a metric space homeomorphic to the real number interval [0, 1] or, equivalently, a continuum having precisely two non-separating points. The arcwise connectedness theorem asserts that if M is a locally connected continuum (more generally, a connected open subset of such a continuum), then every two points of M can be joined by an arc lying entirely in M. With proper care, the desired arc can be obtained as the intersection of a sequence K1 D K2 D K3 D of "thinner and thinner" subcontinua of M. Of course, the notion of thinness must be appropriately defined, and this is usually done by means of chains of (small) sets. A simple chain is a finite sequence W = (C1, C2,. ., C9) of nonempty sets such that every two adjacent terms of the sequence intersect but no two non-adjacent terms do so. The sets C1, C2, . ,C, are called links of C, and if a E C1 and b E C, , then V is said to be a chain from a to b. If 9, and 92 are simple chains such that the concatenation of the sequence 9, followed by the sequence 92 is a simple chain 9, we will write 9 = 91 + 92. Note that if 9 = 91 + 92 + . + 9k, then for i < j each link of 9i precedes each link of 9 in 9. Now suppose M is a locally connected continuum (or a connected open subset of a locally connected continuum) and a, b E M, a 0 b. It is easy to obtain a sequence WI, 9,2 e3, . of simple chains from a to b, Wn = (Cn, C2n, . , Ckn), such that for each n,
Clinical features and outcomes of diffuse large B-cell lymphoma based on nodal or extranodal primary sites of origin: Analysis of 1,085 WHO classified cases in a single institution in China

Objective To explore the clinicobiologic features and outcomes of diffuse large B-cell lymphoma (DLBCL) patients in China according to the primary site. Methods A total of 1,085 patients diagnosed with DLBCL in National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College during a 6-year period were enrolled. Their clinical characteristics and outcomes were analyzed according to the primary site. Results In the 1,085 patients, 679 (62.6%) cases were nodal DLBCL (N-DLBCL) and 406 cases (37.4%) were extranodal DLBCL (EN-DLBCL). The most common sites of N-DLBCL were lymphonodus (64.8%), Waldeyer’s ring (19.7%), mediastinum (12.8%) and spleen (2.7%), while in EN-DLBCL, stomach (22.4%), intestine (16.0%), nose and sinuses (8.9%), testis (8.4%), skin (7.9%), thyroid (6.9%), central nervous system (CNS) (6.4%), breast (5.7%), bone (3.4%), and salivary gland (2.7%) were most common. N-DLBCL patients tend to present B symptoms, bulky disease, and elevated LDH more often, while age >60 years, extranodal sites >1, Ann Arbor stage I or II, bone marrow involvement, and Ki-67 index >90% were usually seen in EN-DLBCL. The 5-year overall survival (OS) rate and progression-free survival (PFS) rate for all patients were 62.5% and 54.2%. The 5-year OS rate for patients with N-DLBCL and EN-DLBCL were 65.5% and 56.9% (P=0.008), and the 5-year PFS were 57.0% and 49.0% (P=0.020). Waldeyer’s ring originated DLBCL possessed the highest 5-year OS rate (83.6%) and PFS rate (76.9%) in N-DLBCL. The top five EN-DLBCL subtypes with favorable prognosis were stomach, breast, nose and sinuses, lung, salivary gland, with 5-year OS rate: 70.3%, 69.6%, 69.4%, 66.7% and 63.6%, respectively. While CNS, testis, oral cavity and kidney originated EN-DLBCL faced miserable prognosis, with 5-year OS rate of 26.9%, 38.2%, and 42.9%. Conclusions In our study, primary sites were associated with clinical characteristics and outcomes. Compared with EN-DLBCL, N-DLBCL had better prognosis.
Properties of formate dehydrogenase in Methanobacterium formicicum

Soluble formate dehydrogenase from Methanobacterium formicicum was purified 71-fold with a yield of 35%. Purification was performed anaerobically in the presence of 10 mM sodium azide which stabilized the enzyme. The purified enzyme reduced, with formate, 50 mumol of methyl viologen per min per mg of protein and 8.2 mumol of coenzyme F420 per min per mg of protein. The apparent Km for 7,8-didemethyl-8-hydroxy-5-deazariboflavin, a hydrolytic derivative of coenzyme F420, was 10-fold greater (63 microM) than for coenzyme F420 (6 microM). The purified enzyme also reduced flavin mononucleotide (Km = 13 microM) and flavin adenine dinucleotide (Km = 25 microM) with formate, but did not reduce NAD+ or NADP+. The reduction of NADP+ with formate required formate dehydrogenase, coenzyme F420, and coenzyme F420:NADP+ oxidoreductase. The formate dehydrogenase had an optimal pH of 7.9 when assayed with the physiological electron acceptor coenzyme F420. The optimal reaction rate occurred at 55 degrees C. The molecular weight was 288,000 as determined by gel filtration. The purified formate dehydrogenase was strongly inhibited by cyanide (Ki = 6 microM), azide (Ki = 39 microM), alpha,alpha-dipyridyl, and 1,10-phenanthroline. Denaturation of the purified formate dehydrogenase with sodium dodecyl sulfate under aerobic conditions revealed a fluorescent compound. Maximal excitation occurred at 385 nm, with minor peaks at 277 and 302 nm. Maximal fluorescence emission occurred at 455 nm.
Cloning of Spy1,a Novel Homolog of afsk Gene

Pristinamycin is an antibiotic of the streptogramin family that is produced by Streptomyces pristinaespiralis.Bacterial strains that engineered to produce pristinamycin producing were rare and non existed in China.We have constructed a cosmid library of a pristinamycin-producing strain and screened the colonies by in situ hybridization,in which a pristinamycin restriction fragment was used for Southern blotting.The target gene in full-length was successfully subcloned and named as Spy1.The construct contained a 2 127 bp open reading frame(ORF),which encodes a protein of serine/threonine protein kinase of 708 amino acids.
Survey on Pancreatic Tumour Segmentation

Pancreatic tumors are abnormal growth of cell in digestive enzymes and hormone producing cell. Pancreatic adenocarcinoma is one of the most aggressive malignant tumors which remain the fourth leading cause of the cancer related death. The prognosis for patients diagnosed with this pancreatic tumor has always remained extremely poor. Unlike brain, pancreas is not protected by skull . It is surrounded by various organs and fatty tissues in the abdomen and hence detection and segmentation is not appropriate. Most of the abdominal CT images include noises along with the visceral fat in the proximity of pancreas makes it very challenging for early detection. Though much work still needs to be done, developments in the field provide the hope for early prediction of pancreatic cancer could become a reality in the not-so-distant future. A comprehensive survey of segmentation of pancreatic tumour is done in this

Short-term Semantic Shifts and their Relation to Frequency Change

We present ongoing research on the relationship between short-term semantic shifts and frequency change patterns by examining the case of the refugee crisis in Austria from 2015 to 2016. Our experiments are carried out on a diachronic corpus of Austrian German, namely a corpus of newspaper articles. We trace the evolution of the usage of words that represent concepts in the context of the refugee crisis by analyzing cosine similarities of word vectors over time as well as similarities based on the words’ nearest neighbourhood sets. In order to investigate how exactly the contextual meanings have changed, we measure cosine similarity between the following pairs of words: words describing the refugee crisis, on the one hand, and words indicating the process of mediatization and politicization of the refugee crisis in Austria proposed by a domain expert, on the other hand. We evaluate our approach against the expert knowledge. The paper presents the current findings and outlines the directions of the future work.
Creativity in temporal social networks: how divergent thinking is impacted by one’s choice of peers

Creativity is viewed as one of the most important skills in the context of future-of-work. In this paper, we explore how the dynamic (self-organizing) nature of social networks impacts the fostering of creative ideas. We run six trials (N = 288) of a web-based experiment involving divergent ideation tasks. We find that network connections gradually adapt to individual creative performances, as the participants predominantly seek to follow high-performing peers for creative inspirations. We unearth both opportunities and bottlenecks afforded by such self-organization. While exposure to high-performing peers is associated with better creative performances of the followers, we see a counter-effect that choosing to follow the same peers introduces semantic similarities in the followers’ ideas. We formulate an agent-based simulation model to capture these intuitions in a tractable manner, and experiment with corner cases of various simulation parameters to assess the generality of the findings. Our findings may help design large-scale interventions to improve the creative aptitude of people interacting in a social network.
Circulating Extracellular Vesicles in Gynecological Tumors: Realities and Challenges

Although liquid biopsy can be considered a reality for the clinical management of some cancers, such as lung or colorectal cancer, it remains a promising field in gynecological tumors. In particular, circulating extracellular vesicles (cEVs) secreted by tumor cells represent a scarcely explored type of liquid biopsy in gynecological tumors. Importantly, these vesicles are responsible for key steps in tumor development and dissemination and are recognized as major players in cell-to-cell communication between the tumor and the microenvironment. However, limited work has been reported about the biologic effects and clinical value of EVs in gynecological tumors. Therefore, here we review the promising but already relatively limited data on the role of circulating EVs in promoting gynecological tumor spread and also their value as non-invasive biomarkers to improve the management of these type of tumors.
Toward a Blueprint for Conservation in Africa

I the last two decades, various quantitative techniques for assessing conservation priorities have been developed, based on data about the distribution of species (Reid 1998, Williams 1998, Margules and Pressey 2000). These methods have been applied extensively in temperate regions such as North America at both the state (Csuti et al. 1997) and national (Dobson et al. 1997) levels. However, biological diversity is concentrated in the tropics, and it is here that conservation faces the most pressing threats (Raven 1988). Furthermore, fine resolution data are often so scarce and local land-use patterns so diverse as to limit our ability to apply quantitative prioritization techniques at fine scales (Pimm and Lawton 1998). Hence, such techniques may be particularly appropriate for application in tropical areas and at continental scales. Until recently this application has been restricted to single families (Kershaw et al. 1994, 1995) or orders (Hacker et al. 1998), because continent-level species distribution data from the tropics are rarely compiled. Recognizing this limitation, the Zoological Museum of the University of Copenhagen embarked on a program to compile continent-level data on the distributions of tropical species. Such data have allowed the use of quantitative conservation prioritization techniques for birds, for which data are better than for other taxa, in both South America and Africa (Burgess et al. 1997, de Klerk 1998, Fjeldså and Rahbek 1997, 1998, 1999). Simultaneously, the museum has compiled data from Africa for three other major taxa: mammals, snakes, and amphibians (Burgess et al. 1998). The Zoological Museum of the University of Copenhagen intends to publish these data as an atlas of African biodiversity. This article begins a series planned to extend these analyses across four major terrestrial taxa, for an entire tropical continent. For each taxon we first present an overview of patterns of species richness and narrow endemism across the continent. Second, we use these patterns to identify areas of high conservation priority that can most efficiently represent each group of species. Finally, we repeat the analysis for threatened species (Baillie and Groombridge 1996), the immediate priorities for conservation in Africa. Numerous important issues remain to be addressed, and we conclude the article with a detailed discussion of them. In our ongoing research we are address four in particular. First is the question of surrogacy—how well do conservation priorities for one taxon represent other taxa? Second is the matter of incorporating socioeconomic variables into the analyses, both as pressure (e.g., human population) and as response (e.g., existing protected areas) variables—the need to do so is urgent. The third issue involves scale: We are using environmental models to increase the resolution of the databases to scales relevant to local (rather than continental) conser-
