Densification mechanisms during reactive spark plasma sintering of Titanium diboride and Zirconium diboride

, Sanjay Kashyap, Devinder Yadav, & Srinivasa R. Bakshi
In this study, dense fine-grained ZrB2 and TiB2 were fabricated using reactive spark plasma sintering (RSPS) of ball-milled Zr/B and Ti/B mixtures. Systematic investigations were carried out to understand the mechanisms of reactive sintering. Two densification mechanisms were found to be operating during RSPS. The first stage of densification was due to self-propagating high temperature synthesis reaction leading to formation of ZrB2 and TiB2 compacts having relative density of ~48 and ~65%, respectively. The second...

Dataset for: Structural study of 1-(2´, 3´-O-isopropylidene-(α-D-allo and –β-L-talofuranosyluron)-5´-cyanohydrin)uracil stereoisomers by NMR spectroscopy and theoretical methods.

The stereochemistry of nucleoside derivatives determines their pharmacological activity such as anticancer, antiviral, against human immunodeficiency virus (HIV) and antimycotic. Therefore, it is necessary to elucidate the structure of each stereoisomer. The isolation and spectroscopic characterization of the 1-(2´, 3´-O-isopropylidene-(α-D-allo and -β-L-talofuranosyluron)-5´-cyanohydrin)uracil stereoisomer is of great importance because these compounds are intermediaries in the development of novel nucleoside derivatives. In this study, we elucidated the structure of 5´(R) and (S)-cyanohydrin stereoisomers by NMR spectroscopy and...

Dataset for: Modulation of host cell SUMOylation facilitates efficient development of Plasmodium berghei and Toxoplasma gondii

, , , Babu S Mastan, Satish Mishra & Arun Kumar Kota
SUMOylation is a reversible post translational modification of proteins that regulates protein stabilization, nucleocytoplasmic transport and protein-protein interactions. Several viruses and bacteria modulate host SUMOylation machinery for efficient infection. Plasmodium sporozoites are infective forms of malaria parasite that infect hepatocytes and transforms into exoerythrocytic forms (EEFs). Here we show that, during EEF development, the distribution of SUMOylated proteins in host cell nuclei was significantly reduced and expression of the SUMOylation enzymes was downregulated. Plasmodium EEFs...

Biphonal calls in Atlantic spotted dolphins (Stenella frontalis): bitonal and burst-pulse whistles

, Kelly Melillo-Sweeting & Diana Reiss
Biphonation, the simultaneous production of two sounds by a single animal, is found in the vocalizations of a range of mammalian species. Its prevalence suggests it plays an important role in acoustic communication. Concurrent vocal and behavioural recordings were made of Atlantic spotted dolphins (Stenella frontalis) off Bimini, The Bahamas. The occurrence of two types of biphonal signals is reported: burst-pulse whistles with combined tonal and burst-pulse elements, and bitonal whistles. Biphonal whistles are rarely...

Impact of different educational interventions on psychosocial well-being of women with a positive high-risk human papillomavirus and normal cervical cytology: a randomised trial

, Na Wei, Tracy T. C. Kwan, Mandy M. Y. Chu, Ka Yu Tse, Karen K. L. Chan &
Introduction: The aim of this study was to compare the effect of two educational interventions on the psychosocial well-being of Hong Kong Chinese women who have a positive high-risk human papillomavirus (HPV) test and normal cervical cytology. Methods: Participants were randomised into either leaflet group, in which a written HPV factsheet was provided; or counselling group, in which a didactic HPV presentation in person in addition to the factsheet was provided. Women’s psychological conditions were...

Supplementary material from Computational design of treatment strategies for proactive therapy on atopic dermatitis using optimal control theory

Panayiotis Christodoulides, Yoshito Hirata, Elisa Domínguez-Hüttinger, Simon G. Danby, Michael J. Cork, Hywel C. Williams, Kazuyuki Aihara & Reiko J. Tanaka
Atopic dermatitis (AD) is a common chronic skin disease characterized by recurrent skin inflammation and a weak skin barrier, and is known to be a precursor to other allergic diseases such as asthma. AD affects up to 25% of children worldwide and the incidence continues to rise. There is still uncertainty about the optimal treatment strategy in terms of choice of treatment, potency, duration and frequency. This study aims to develop a computational method to...

Two new stilbene trimers from Cynodon dactylon

Bi-Jun Li, Yao Liu, , Qing Zhang, Lei Chen, Shu-Mei Wang & Feng Wang
Many naturally occurring oligostilbenes have drawn considerable attention because of their intricate structures and diverse bioactivities. Two new stilbene trimers, cystibenetrimerol A (1) and cystibenetrimerol B (2) were isolated from the dried grass of Cynodon dactylon (L.) Pers. The planar structures and stereo configurations of them were elucidated by spectroscopic and spectrometric methods. The isolation and structures elucidation of two new stilbene trimers suggested the ordinary grass belonging to the family Poaceae may be a...

Evolutional models of cultural transmisison in Palaeolithic Archaeology

Attila Király
Paper presented at the 10th MOMOS conference in Százhalombatta, Hungary (in Hungarian). Az átadás technikáinak evolúciós modelljei a paleolitikum régészetében. A régibb kőkor régészetét hagyományosan szoros kapcsolat fűzi olyan evolúciós programokhoz, mint a megismeréstudomány, viselkedésbiológia, paleoantropológia. Ebben a viszonyrendszerben a kultúra egyedülálló adaptáció, sajátos kognitív képességeinkből táplálkozó, állandóan bővülő tudástár, amit nem génjeink által, hanem átadással és tanulással örökítünk tovább. Modellezhetjük a kulturális átadás technikáit az öröklés biológiai mechanizmusaival? Mit árulnak el a kőeszközkészítés változó...

Supplemental Video 2 from The roles of impact and inertia in the failure of a shoelace knot

Christopher A. Daily-Diamond, Christine E. Gregg &
The accidental untying of a shoelace while walking often occurs without warning. In this paper, we discuss the series of events that lead to a shoelace knot becoming untied. First, the repeated impact of the shoe on the floor during walking serves to loosen the knot. Then, the whipping motions of the free ends of the laces caused by the leg swing produce slipping of the laces. This leads to eventual runaway untangling of the...
