Aspects of repurposed yarns

The world is facing an increasing problem of textile waste. Repurposing is a method of using textile waste as a raw material. There are several techniques which fall under repurposing methods. Creating yarns from the textile waste is one of the techniques which fall under repurposing methods. There is a lack of study on the specific subject of repurposed yarns. The objective of this study is to understand the various aspects of (characteristics and limitations) of repurposed yarns through user research. The study relies on primary research of semi structured interviews conducted on 10 prominent users including textile manufacturers and designers of repurposed yarns. Data Analysis was done using grounded theory through which aspects and attributes of repurposed yarns are highlighted.
Comments on the CrossTalk opposing views: Peripheral and central chemoreflexes have additivehypoadditivehyperadditive effects on ventilation in humans

Chemoreflexes regulate normal breathing by responding quickly to small changes in PCO2 . They also respond to abnormal conditions, e.g. the response to hypoxia begins at PaO2 values well below normal, and in sleep apnoea, chemoreflexes respond to asphyxia and limit the apnoea. Apnoea can be mimed by voluntary breath-holds during which PaCO2 rises quickly to mixed venous values while PaO2 falls continuously, i.e. progressive asphyxia. In response to chemoreflex stimulation, normal subjects ‘break’ the breath-hold after 60 s (PAO2 70 mmHg and PACO2 50 mmHg). Both chemoreflexes contribute to the ‘break’ as breath-hold duration is longer when starting at either low CO2 or high O2. Likewise, sleep apnoeas can last up to 60 s (Findley et al. 1965), accompanied by increased CO2 and decreased O2, and terminated via chemoreflexes. The CrossTalk chemoreflex studies, like most (Nattie & Li, 2012), do not mime repeated asphyxia. Repeated asphyxia can produce pulmonary hypertension in adults and participate in the pathogenesis of the sudden infant death syndrome (SIDS) (Randall et al. 2013), in which the brainstem serotonergic (5–HT) system is abnormal (Duncan et al. 2010). Experimentally induced 5–HT dysfunction is associated in adults with a reduced CO2 chemoreflex (Ray et al. 2011) and in neonates with abnormal responses (including mortality) to repeated brief asphyxia (Cummings et al. 2013). In the context of this CrossTalk, a hyperadditive chemoreflex in asphyxia would be useful to the organism. Future studies to examine chemoreflex interaction might examine responses to rapid changes in CO2 and O2 using other approaches, e.g. pseudo-random single breath application (Lai & Bruce, 1997).
Dimethylsul¢de is an energy source for the heterotrophic marine bacterium Sagittulastellata

Dimethylsulﬁde (DMS) is a volatile organosulfur compound, ubiquitous in the oceans, that has been credited with various roles in biogeochemical cycling and in climate control. Various oceanic sinks of DMS are known – both chemical and biological – although they are poorly understood. In addition to the utilization of DMS as a carbon or a sulfur source, some Bacteria are known to oxidize it to dimethylsulfoxide (DMSO). Sagittula stellata is a heterotrophic member of the Alphaproteobacteria found in marine environments. It has been shown to oxidize DMS during heterotrophic growth on sugars, but the reasons for and the mechanisms of this oxidation have not been investigated. Here, we show that the oxidation of DMS to DMSO is coupled to ATP synthesis in S. stellata and that DMS acts as an energy source during chemoorganoheterotrophic growth of the organism on fructose and on succinate. DMS dehydrogenase (which is responsible for the oxidation of DMS to DMSO in other marine Bacteria ) and DMSO reductase activities were absent from cells grown in the presence of DMS,
Frictional Behaviour of the Microstructural Surfaces Created by Cylindrical Grinding Processes

Featured Application: It is well known that micro geometrical topographic characteristics have a strong inﬂuence on the surface tribological performance. However, it has been a difﬁculty for a long time for engineers to identify a set of suitable grinding parameters that could create low friction surfaces. Based on the understanding the mechanism of grinding surface generation, the paper presents a new set of surface feature parameters that could form a function in related to the frictional performance of the ground surface. Such a function could guide engineers to create beneﬁcial microstructural features for lower friction bearing surfaces to improve energy efﬁciency of the applications. Abstract: Cylindrical surface grinding can create deﬁned textural patterns on a component with high quantity. This paper presents an experimental investigation of the frictional behaviours of ground cylindrical microstructural surfaces under a well lubrication condition. It shows that the coefﬁcient of friction (COF) of microstructural surface is inﬂuenced by different workload and rotation speed. The results reveal that conventional surface roughness parameters do not present the inﬂuence of surface microstructure on friction performance well. However, the paper presents an interesting discovery that the friction behaviour of microstructural surfaces created by grinding could be controlled by combining dressing and grinding conditions. Such a discovery provides a logic way to reduce surface friction for energy efﬁciency applications. A few functional relationships have been established to illustrate the inﬂuence of microstructural features on friction. It was found that the ground microstructural surface could improve friction performance up to 20% compared to the smoother surfaces without deﬁned surface textural patterns.
Phyto-indication of Pollution in Romi stream, Kaduna Nigeria using Pistia Stratiotes

There is scanty literature information comprising of both physico-chemical and phyto-indication study of Romi stream as Most of the past investigations on Romi stream concentrate on physicochemical parameters and heavy metals concentration in the stream water. This research there by aimed at investigating the Physico-chemical characteristic and phyto-indication profile of Romi stream using Pistia stratiotes. Water samples were collected in five different points (point A, point B, point C, point D and point E) for the period of 12 months (September, 2016 to August, 2017). Physico-chemical parameters of the sampled water were determine and the phytoincatory role of pistia stratiotes was investigated by the determination of bioconcentration factor (BCF) and biotranslocation factors (BTF). Data were analyzed using Spss software version 20.0 by IBM Company to test for Turkish test significance at 0.05 across the sampling points and the seasonal mean. Turkey‟s multiple comparison at (P<0.05) revealed that most of the physic-chemical parameters measured have significant change which could be attributed to the discharge of refinery effluent into the stream water. Pistia stratiotes also shows high BTF and BCF signifying high pollution resulting from the discharge of refinery water since BTF and BCF increase across the points from point A to point E. It is thereby recommended that regulatory body such as Kaduna State Protection Agency (KEPA) should make sure that Kaduna Refining and Petrochemical Company treated its waste water properly using both chemical and biological method before discharging into the Romi stream,
Early Soft Tissue Response to Zirconium Oxide and Titanium Healing Abutments in Vivo: A Dog Study

Background: This study aimed to investigate clinical characteristics and early soft tissues response to zirconium oxide (Zr) and titanium (Ti) abutments in dogs. Methods: Eight implants-four at each hemi-mandible were inserted after bilateral mandibular third and fourth premolars and first molars extraction. Two Zr and two Ti healing abutments were connected in each unilateral mandible 8 weeks later. The ligation method was used to make peri-implant mucositis model. The twenty-four abutments were divided into four groups, Zr and Ti healing abutments with ligation (ZrL, TiL) and non-ligation (ZrN, TiN) groups. Clinical index, peri-implant crevicular fluid (PICF) and inflammatory cytokines (TNF-α and IL-1β), soft tissue responses were tested. Two-way analysis of variance was used to analyze the data. Results: The results showed that the clinical index were similar around Zr and Ti healing abutments. PICF in ZrL and TiL groups were significantly higher than those in ZrN and TiN groups. Immunohistochemistry demonstrated inflammatory cells were non-significant differences. Conclusion: These data indicate soft tissue responses to Zr healing abutments with peri-implant mucositis was comparable to those to Ti healing abutments in vivo, and can provide theoretical foundation for Zr’s clinical application.
Effects of slenderness coefficient in crown area prediction for Tectona grandis Linn. f. in Omo Forest Reserve, Nigeria

Crown area which is crown size, is closely related to the photosynthetic capacity of tree and it is an important parameter to characterize biomass, leaf area and wildlife habitats. Conversely, assessment of crown dimensions still remain one of the most difficult and tedious task in forestry. The difficult measurements and the sensitivity of crown dimension on management makes it desirable to develop estimation procedures based on variables that are easier to measure than crown extension itself. The main objective of this study was to develop and observe the effects of tree slenderness coefficient in predicting crown area for Tectona grandis in Omo Forest Reserve. Twenty temporary sample plots of size 20 m x 20 m were randomly selected across the stand ages (9, 11, 12 and 18 years). Tree growth variables measured from each plot include diameter at breast height (Dbh) ≥ 5 cm, total height (THt) and crown diameter (CD). The data was analysed using descriptive, correlation and regression analyses. Amidst the models developed and verified, double logarithmic function with adj. R 2 = 62.0%, RMSE = 0.265% and PRESS = 0.263 gave the best fit and predictive ability. This was also supported by the undeviating bands of the graphical analyses of the residual. Conversely, the inclusion of TSC had impact on the predictive abilities of the models which implies that slenderness coefficient typically indicates the size of crown dimension, centre of gravity and a better developed root system. Therefore, it is recommended that the model can be used by forest managers for the development of stocking guideline.
An immune-related gene pairs signature predicts overall survival in serous ovarian carcinoma

Background: Ovarian cancer has the highest death rate of all fatal gynecological cancers. Increasing evidence has depicted the correlation between serous ovarian carcinoma prognosis and immune signature. Therefore, the aim of this study is to develop a robust prognostic immune-related gene pairs (IRGPs) signature for estimating overall survival (OS) of HGSOC. Methods: Gene expression pro ﬁ ling and clinical information of serous ovarian carcinoma patients were derived from three public data sets, divided into training and validation cohorts. Immune genes signi ﬁ cantly associated with prognosis were selected. Results: Among 1,534 immune genes, a 20 IRGPs signature was built which was signi ﬁ cantly associated with OS in the training cohort ( P =1.44×10 − 14 ; hazard ratio [HR] =3.05 [2.26, 4.10]). In the validation datasets, the IRGPs signature signi ﬁ cantly divided patients into high- vs low- risk groups considering their prognosis ( P =4.30×10 − 3 ; HR =1.48 [1.13, 1.95]) and was prognostic in multivariate analysis. Functional analysis showed that several biological processes, including EMT and TGF- β related pathways, enriched in the high-risk group. Macrophages M2 was signi ﬁ cantly higher in the high-risk group compared with the low-risk group. Conclusion: We successfully constructed a robust IRGPs signature with prognostic values for serous ovarian carcinoma, providing new insights into post-operational treatment strategies.
Isolation and Functional Analysis of a MYB Transcription Factor Gene that is a Key Regulator for the Development of Red Coloration in Apple Skin

Red coloration of apple ( Malus (cid:1) domestica ) skin is an important determinant of consumer preference and marketability. Anthocyanins are responsible for this coloration, and their accumulation is positively correlated with the expression level of anthocyanin biosynthetic genes. Regulation of expression of these genes is believed to be controlled by MYB transcription factors, and the MYB transcription factors involved in the activation of anthocyanin biosynthetic genes have been isolated in various plants. In the present study, we isolated and characterized a MYB transcription factor gene ( MdMYBA ) from apple skin. Characterization of MdMYBA demonstrated that (i) MdMYBA expression was specifically regulated depending on the tissue and cultivar/ species; (ii) its expression level was much higher in a deep-red cultivar (‘Jonathan’) than in a pale-red cultivar (‘Tsugaru’); (iii) when cauliflower mosaic virus 35S::MdMYBA was introduced into the cotyledons of apple seedlings by means of a transient assay, reddish-purple spots were induced, and MdMYBA also induced anthocyanin accumulation in reproductive tissues of transgenic tobacco; (iv) the expression of MdMYBA was induced by UV-B irradiation and low-temperature treatment, both of which are known to be important in the promotion of anthocyanin accumulation in apple skin; (v) MdMYBA bound specifically to an anthocyanidin synthase ( MdANS ) promoter region in a gel-shift assay; and (vi) MdMYBA was mapped to the near region of the BC226-STS (a 1 ) marker for the red skin color locus ( R f ). These results suggest that MdMYBA is a key regulatory gene in anthocyanin biosynthesis in apple skin. The nucleotide sequences reported in this paper have been submitted to DDBJ under accession numbers AB279598 ( MdMYBA ) and AB279599 ( MdANS promoter).
Gentamicin compared with Ceftriaxone for the treatment of gonorrhoea: a randomised trial (G-ToG Trial)

harbour ceftriaxone resistant gonococci. Further research is required to identify and test new alternatives to ceftriaxone for the treatment of gonorrhoea. Abstract Background: Gonorrhoea is a common sexually transmitted infection for which ceftriaxone is the current first line treatment, but antimicrobial resistance is emerging. The objective of this study was to assess the effectiveness of gentamicin as an alternative to ceftriaxone (both combined with azithromycin) for treatment of gonorrhoea. Methods: We performed a blinded, non-inferiority randomised trial in 14 sexual health clinics in England. Adults with a diagnosis of uncomplicated genital, pharyngeal or rectal gonorrhoea were randomised using a secure web based system, stratified by clinic. Allocation was either to gentamicin 240 mg or to ceftriaxone 500 mg, both administered as a single intramuscular injection. All participants also received 1 g oral azithromycin. The primary outcome was clearance of Neisseria gonorrhoeae at all infected sites. Findings: We enrolled 720 participants and randomly assigned them to gentamicin (n=358) or ceftriaxone (n=362), with 292 and 306, respectively, included in the primary analysis. Non-inferiority of gentamicin to ceftriaxone was not demonstrated (adjusted risk difference for microbiological clearance -6.4%, 95% CI -10.4%, -2.4%, NI margin -5%). Clearance of genital infection was similar in the two groups: 94% gentamicin versus 98% ceftriaxone: but for pharyngeal and rectal infections were lower in the gentamicin group (80% vs 96% and 90% vs 98%, respectively). The side effect profiles were comparable between the allocated groups, other than reported pain at the injection site, which was higher for gentamicin.
COMMUTING MAPS: A SURVEY

A map $f$ on a ring $\cal A$ is said to be commuting if $f(x)$ commutes with $x$ for every $x\in \cal A$. The paper surveys the development of the theory of commuting maps and their applications. The following topics are discussed: commuting derivations, commuting additive maps, commuting traces of multiadditive maps, various generalizations of the notion of a commuting map, and applications of results on commuting maps to different areas, in particular to Lie theory.
4D-STEM analysis of an amorphous-crystalline polymer combined nanocrystalline and RDF mapping

Nanoscale morphology of multiphase polymer systems and blends, particularly at and near interfaces, is critical to understanding interphase adhesion mechanisms and their impact on bulk mechanical properties [1-2] . To visualize this morphology over a representative sampling, a fast high-resolution technique for mapping both crystalline and amorphous domains with a large field of view is needed. Transmission electron microscopy (TEM) offers the high resolution needed. However, the application of TEM to polymers is severely limited by the electron beam sensitivity, low scattering intensity from low-Z elements, and difficulty in differentiating polymers which often have close chemical and structural makeup. To circumvent this traditionally, a heavy metal stain is used to introduce artificial contrast, but this contrast can be very difficult to interpret as it provides little structural information and often results in artifacts. Four-dimensional scanning TEM (4D-STEM) is an emerging technique with high spatial resolution over a relatively large sample area which provides a wealth of structural information [3] . However, beam damage has limited its applications for soft materials and polymeric blends . Here we explore the use of high-speed detectors, small condenser apertures, and high throughput processing software for 4D-STEM characterization of both the amorphous and crystalline regions of polymer blends. Specifically, we demonstrate a low-dose 4D-STEM technique for visualizing nanostructure in extremely beam sensitive semicrystalline isotactic polypropylene and ethylene-octene copolymer
Community pharmacy personnel interventions for smoking cessation Review information

Community pharmacists could provide effective smoking cessation treatment because they offer easy access to members of the community. They are well placed to provide both advice on the correct use of smoking cessation products and behavioural support to aid smoking cessation. of support offered, but mostly started before quit day and followed up with continued appointments for several weeks afterwards. These support programmes were compared with either minimal or less intensive behavioural support for smoking cessation, typically comprising a few minutes of one-off advice on how to quit. Participants in both the intervention and control arms received equivalent smoking cessation pharmacotherapy in all but one study. This review cannot tell us about the efficacy of pharmacy-based support in comparison with no support or relative to other forms of delivery. Similarly, no studies assessed the effectiveness of pharmacists compared with other health professionals providing a comparable programme, nor with pharmacy personnel other than pharmacists. We have therefore only been able assess the effectiveness on of a programme by the team compared with a delivered by a over in 2000 database. Baseline categorical variables by intervention were compared using the Chi 2 test and the 2-sample t-test
IPO UNDERPRICING IN THE TECH SECTOR: IMPACT OF THE PROSPECTUS SUMMARY VARIABLES

Aiming to provide guidance to researchers regarding publicly available factors associated with tech IPO underpricing, this thesis investigates the impact of the information contained on the prospectus summary on underpricing. In a sample of 131 tech IPOs listed in the U.S. between 2010-2017, was found evidence that IPOs with larger spreads are associated with more underpricing, IPOs with larger gross proceeds and with dual-class shares underprice less and that book-to-market ratio and underwriter reputation do not have significant impact on underpricing. Great majority of the results challenge hypothesis derived upon previous literature. Inherent characteristics of the tech industry, advances on information technology, continuous regulatory changes, increase in regulatory scrutiny and changes on U.S. IPO market trends were proposed and discussed to be drivers of such outcome.
A wearable textile-based pneumatic energy harvesting system for assistive robotics

Wearable assistive, rehabilitative, and augmentative devices currently require bulky power supplies, often making these tools more of a burden than an asset. This work introduces a soft, low-profile, textile-based pneumatic energy harvesting system that extracts power directly from the foot strike of a user during walking. Energy is harvested with a textile pump integrated into the insole of the user’s shoe and stored in a wearable textile bladder to operate pneumatic actuators on demand, with system performance optimized based on a mechano-fluidic model. The system recovered a maximum average power of nearly 3 W with over 20% conversion efficiency—outperforming electromagnetic, piezoelectric, and triboelectric alternatives—and was used to power a wearable arm-lift device that assists shoulder motion and a supernumerary robotic arm, demonstrating its capability as a lightweight, low-cost, and comfortable solution to support adults with upper body functional limitations in activities of daily living.
Supplementary honey bee (Apis mellifera L.) pollination enhances fruit growth rate and fruit yield in Paeonia ostii (family: Paeoniaceae)

Insufficient pollination leads to low and unstable production of oil tree peony. Supplementary managed honeybees (Apis mellifera L.) in agricultural ecosystems is a common practice for addressing the problem. At this study site (N 34°38′30″ and E 112°39′43″, with an altitude of 125.5 m), we set up four pollination areas (low-density bee pollination group (LDBP), high-density bee pollination group (HDBP), blank control group (CK1) and field control group (CK2)) to examine the pollination effectiveness of different densities of honeybee supplementation on oil tree peony (Paeonia ostii). Our work demonstrated that bee-pollination increased fruit size and growth rate. On average, bee-pollinated (LDBP) plants produced 63.16% more number of seeds per plant, showed also 53.47% more weight of seeds per plant than those in CK2. Also, seeds of LDBP contained, on average, 26.15% more oil content than CK2. Kernel percent and seed oil fatty acid content, however, were unaffected (F = 1.759, p = 0.074). Compared with LDBP, weight of seeds per plant and oil content with HDBP decreased by 21.89% and 2.63%, respectively. Following the same trend, compared with LDBP, HDBP slowed fruit growth and reduced fruit size. Our results showed that insufficient pollination limits fruit set in oil tree peony, while supplementary reasonable bee density in the field for pollination is an important strategy to maximize fruit yield.
