Study of iPP crosslinking by means of dynamic and steady rheology measurements

Field: Materials Science (Physical Sciences)

Abstract The crosslinking of isotactic polypropylene (iPP) using crosslinking agents (CAs) based on a peroxide/sulfur/accelerator system is a very attractive new method that has been reported recently. The present work deals with the study of the dynamic rheological behavior of iPP during and after the crosslinking process. The influence of the CA concentration and the processing temperature T on the rheological behavior of the iPP was analyzed. The kinetics of the crosslinking reaction was established using the technique described by G. A. Harpell and D. H. Walrod. This reaction is found to be of order one. At T = 180°C, the crosslinking reaction was faster. By varying the crosslinking agent content, different crosslinking degrees of iPP, expressed by the corresponding gel content, are achieved. On the other hand, the modified polypropylene exhibits an unexpected viscosity‐shear rate pattern, which describes the reverse crosslinking reaction mainly occurring by the opening of the bridges of the new interpenetrating network (IPN) formed. © 2011 Wiley Periodicals, Inc.

Projecting the effects of climate change on prey selection and dietary competition in communities of European reedbed warblers

Field: Agricultural and Biological Sciences (Life Sciences)

Climate change remains one of the greatest threats to natural systems worldwide. Songbirds are sensitive to changes in invertebrate prey resources and may respond to climate-mediated shifts by either broadening or narrowing the range of prey types consumed. This PhD used a latitudinal gradient as an analogue for future climate change, to explore how warming might alter diet, prey selectivity and dietary overlap in reedbed warblers breeding in Europe. The diets of six reedbed warbler species along the gradient were elucidated via metabarcoding of prey remains in faecal samples. Local weather, prey availability and warbler diets in the reedbeds of Catalonia (southern Europe) were monitored and compared with northern and southern reedbed sites in England and Wales (UK), to infer future patterns of prey availability and changes to potential competitive responses by warblers to future warming across the gradient. \nEach warbler species showed subtle differentiation in diet; as did different age classes of the reed warbler (Acrocephalus scirpaceus); including the size of prey captured, taxonomic composition, and the proportion of aquatic and terrestrial arthropods consumed (Chapter 2, 3 and 4). Partitioning was often masked by high dietary overlap when local prey abundance was high, but lower overlap was observed during scenarios of lowered prey abundance. Changes in dietary overlap were also associated with maximum temperature and rainfall, with contrasting responses in the two countries, likely mediated through impacts upon local warbler prey (Chapter 5). The extent of overlap along the gradient could be predicted using a continuum of prey abundance and richness. \nOur findings have implications for sympatric birds in both the UK and Spain, potentially affecting future competitive interactions and coexistence. These consequences may be alleviated by carefully controlled habitat restoration and management, with the aim of promoting aquatic
Direct marketing of beef in organic suckler cattle farms: economic results and impact on breeding system management

Field: Agricultural and Biological Sciences (Life Sciences)

In response to the bovine crises of 1996 and 2000, and also to the poorly structured organic beef market chain, direct marketing of beef to consumers by the farmer has developed. We studied the impact of this marketing system on economic performance and farming practices. The results show that direct marketing can generate added value, despite the extra costs. Farmers have made the necessary changes to their practices, and have adapted their herd management. Through strengthening the link between the farm and the outside world, direct marketing offers an alternative to the expansion of farms, making it possible to support a greater workforce with the same structure.

Field: Agricultural and Biological Sciences (Life Sciences)

Separately under the low temperature coercion of 0℃ and 5℃,experimental studies are made of changes of a series of physiological targets of fresh-cut branches of fortunate bamboo(Dracaena sanderiana) through using different concentrations of salicylic acid(SA).The results have indicated that,after the SA processing,under two kinds of low temperature coercion condition,fortunate bamboo leaf blades' protection enzymatic system activeness,its chlorophyll fluorescence parameter Fv/Fm ratio and its dissociation proline content will increase to a certain extent,its protoplasmic membrane penetrability is lower than the control,simultaneously the malondialdehyde(MDA) content also is lower than the control.Under the condition of 0℃ and 5℃,the SA density respectively is 1 mmol·L-1 and 0.5 mmol·L-1,and have the most obvious function on the fortunate bamboo's cold resistant enhancement.
Learning Analytics in Higher Education

Field: Social Sciences (Social Sciences)

It is known that big data has penetrated several if not all spheres of life. In higher education, the ability to take these large amounts of data and process it into something meaningful for academic decision making is commonly referred to as learning analytics. This chapter provides an overview of learning analytics and its importance, as well as identifying academic data sources, techniques used for learning analytics and prediction, and data visualisation techniques used to present analysis for better understanding and eventual decision making. It also includes a discussion of learning analytics frameworks for research and some identified research challenges.
CW Measurement of Sound Velocity Difference in Two Liquids

Field: Engineering (Physical Sciences)

A technique for measuring the sound velocity difference in two liquids which makes use of interdigital transducers is developed. There exists a linear relationship between the sound velocity difference in two liquids and the phase difference of two delayed output signals, which is converted to a dc voltage by using a phase comparation technique. A prototype with an 10.0 MHz input signal and three times reflections at the liquid cavity surface is fabricated and tested successfully.
A facile and straightforward immersion approach to enhance the hydrophobicity of melamine sponge for efficient cleanup of crude oils and organic solvents

Field: Environmental Science (Physical Sciences)

Abstract The use of biomass-modified hydrophobic materials for cleaning up spilled oils and organic solvents from the environment is currently in high demand. In this study, we developed a simple immersion strategy to modify commercial melamine sponge (MS) using a tetrahydrofuran (THF) extract solution of biomass such as corn stove, pine, and Eucalyptus. This modification process resulted in a highly hydrophobic absorbent with satisfactory superoleophilicity towards various oils (104 g.g -1 ) and organic solvents (137 g.g -1 ). The modified MS demonstrated a good oil adsorption capacity with a contact angle of more than 130°. Remarkably, it also exhibited excellent properties of mechanical extrusion, harsh temperature treatment, and recyclability, owing to its three-dimensional high porosity and micro/nano-structure that trap air. Moreover, we found that other biomass extraction solutions such as γ-valerolactone, N, N-dimethylformamide, acetone, methanol, and ethanol could also serve as suitable modification agents to prepare hydrophobic MS through an immersion strategy. The hydrophobicity and stability of the modified MS obtained using this approach were superior to the lignin-modified and DES-extracted lignin-modified MS. Our findings open up new possibilities for the fabrication of modified MS with high hydrophobicity, using a facile, cost-effective, and environmentally-friendly dipping approach for the cleanup of spilled oils and organic solvents.
Effect of Sodium Barbital on the Physico-chemical Properties of Surfactants with Different Charges

Field: Chemistry (Physical Sciences)

The effects of sodium barbital (SB) on the solubility of different kinds of surfactants viz., CTAB (cationic head group), SDS (anionic head group) and Triton X-100 (non ionic head group) in solution phase as well as their first and second critical micelle concentrations (CMC1 and CMC2), the change in Kraft temperatures (TK) and cloud points (CP) have been studied. Furthermore, the article reports SB-surfactant interaction study, which is application oriented and highlights the underlying physico-chemical aspects of the system through florescence and conductivity measurements. The results show that the solubility of CTAB and Triton X-100 increases with the addition of SB, and that of SDS increases in the presence of small amounts of SB and decreases in the presence of large amounts of SB. With the increasing SB concentration, the CMC of CTAB and CMC1 of Triton X-100 both increase, while the CMC of SDS decreases, and the CMC2 of Triton X-100 has no obvious change. The addition of SB decreases the TK of CTAB sharply, but it increases the TK of SDS and the CP of Triton X-100. The different effects of SB on the physico-chemical properties of differently charged surfactants may be related to its different interactions with the surfactants.

Field: Agricultural and Biological Sciences (Life Sciences)

Howell, B.R., 1984. The intensive rearing of juvenile cod, Gadus morhuo L. In: E. Dahl, D.S. Danielssen, E. Moksness and P. Solemdal (Editors), The Propagation of Cod Godus morhua L. Fladevigen rapportser., 1, 1984: 657-675. Cod were reared in the laboratory from the egg to marketable size using cultured live foods for the early stages and then artificial diets. Survival to metamorphosis was about 10%; subsequent mortalities were negligible. The techniques developed for rearing larval turbot were broadly applicable to the cod. The larvae were fed initially on rotifers, with frequent additions of lsochrysis to the tanks, and then on Artemia. Nauplii freshly hatched from San Francisco eggs were inadequate as food but were improved when fed for 2 days on lsochrysis before being offered. No such treatment was necessary for nauplii hatched from Brazilian eggs Post-metamorphosis growth rates varied from 1.9 to 2.8 cm/month at mean temperatures ranging from 6 to 17OC. The optimum temperature for growth appeared to be around 10-12OC. The prospects and problems of mass-producing juvenile cod in hatcheries are discussed.

Design of polarization-dipole-induced isotype heterojunction diodes for use in III–N hot electron transistors

Field: Engineering (Physical Sciences)

The design of III–nitride-based hot electron transistors (HETs) is investigated using different diode design methodologies. Barrier-limited forward bias current and low reverse leakage current are demonstrated for the emitter-base diode using a barrier formed by a high-Al% AlGaN layer as a polarization-dipole layer. Two different base-collector diode designs are compared, one using 30% AlGaN as the barrier and the other using 10% InGaN as a polarization-dipole barrier. The InGaN polarization-dipole approach is shown to exhibit much lower reverse leakage currents. The impact of threading dislocation density on diode characteristics is also discussed.
The role of histopathology in the diagnosis and management of coeliac disease and other malabsorptive conditions

Field: Medicine (Health Sciences)

Most absorption of nutrients takes place in the proximal small intestine, and the most common disorders leading to malabsorption are associated with a morphological abnormality in the duodenal mucosa that is appreciable in histological sections of biopsy specimens. Coeliac disease is the most well‐known example, causing intraepithelial lymphocytosis, inflammation and villous atrophy in the duodenum. Remarkably similar inflammatory changes can be induced by other processes, including medications, e.g. angiotensin II receptor blockers and immune checkpoint inhibitors, immune dysregulation disorders, e.g. common variable immunodeficiency and autoimmune enteropathy, infections, collagenous sprue, and tropical sprue. However, there are often subtle histological differences from coeliac disease in the type of inflammatory infiltrate, the presence of crypt apoptosis, and the extent and type of inflammation beyond the duodenum. The clinical setting and serological investigation usually allow diagnostic separation, but some cases remain challenging. Histopathology is also important in assessing the response to treatment, such as the change in villous architecture caused by a gluten‐free diet, or the response to cessation of a potentially causative medication. This review examines the practical role that histopathology of duodenal biopsy specimens plays in the assessment and management of inflammatory malabsorptive processes of the proximal small intestine, with a particular emphasis on coeliac disease.
Shakespeare’s Machiavellian Moment: Discovering Ethics and Forming a Leadership Narrative inHenry V

Field: Arts and Humanities (Social Sciences)

Shakespeare’s Henry V, like the historical Henry V, was an enlightened and effective executive leader. Shakespeare attributes part of Henry’s success to adroit image manipulation and unhesitating decisiveness, presenting him as a proto-Machiavellian prince. But in Henry V, Shakespeare also paints a portrait of a prince who acts with restraint, adheres to a well-defined moral framework, and refrains from extremes in pursuit of policy objectives. The changing social and political context of Henry’s England called for a new model of leadership, and Henry adapted himself to tackle these realities through a deliberately constructed leadership narrative.

Field: Engineering (Physical Sciences)

Three-dimension finite element model is built according to the actual structure of model ZJ40/2250DB-drilling rig derrick and substructure.The finite analysis software is applied to static and dynamic characteristic study of derrick and substructure.Two sorts of loads are respectively exerted on the finite model and reliable result is obtained in the course of static analysis.By the model analysis of derrick and substructure,the preceding 4 steps modal frequencies and the corresponding vibration modes are calculated and analyzed.By means of the comparison basic frequency of derrick and substructure with the design rotary speed of drilling machine,it is known that the preceding 4 steps modal frequencies are in the range of rotary table frequencies and they are easy to produce sympathetic vibration.It is suggested to examine the speed of rotary table and avoid sympathetic vibration in the course of drilling.
Co‐operation or coercion? Supplier networks and relationships in the UK food industry

Field: Business, Management and Accounting (Social Sciences)

As a result of several high profile food scares in recent years, the practices of key players in the UK food industry have been called into question on ethical grounds. These practices include a range of operational activities including those concerned with supply chain management which form the focus of this study. This paper utilises an interpretive methodology to examine the buyer‐supplier relationships in the food industry from the perspectives of manufacturing managers and food regulators. The paper utilises the transcripted data from 20 interviews with senior officials from the UK’s food regulation services and from marketing and quality managers working in the food processing and production industry. The study demonstrates the application of interpretive analysis and interview technique to establish the issues concerning the food industry network in the UK today. This is set against Craig Smith’s model of ethical stance and decision making which serves as the backdrop to explicating the respondents’ perspectives on the food industry of the UK. Reveals coercive practices at work in the supply chain and details how this manifests in the lives of regulators and manufacturing managers and in the operations of the companies they work with.
The structure of a shock electromagnetic wave synchronous with several waves propagating in coupled transmission lines with different types of dispersion

Field: Physics and Astronomy (Physical Sciences)

A shock electromagnetic wave is studied numerically in the case when its structure is equally defined by two or more synchronous waves. The analysis relies on the previously suggested electrodynamic system of two coupled transmission lines one of which is normally dispersive (coaxial line) and the other is anomalously dispersive (ladder-type bar slow-wave structure).

A study of association between breastfeeding and iron-deficiency anemia status in infants and young children between 0 and 2 years

Field: Medicine (Health Sciences)

Background: Iron deficiency is one of the biggest contributing factors to the global burden of anaemia. It is an indicator of both poor nutrition and poor health. Results of recent basic research support the concerns that IDA during infancy and childhood can have long lasting detrimental effects on neurodevelopment. Objective: To study contributing factors for IDA in infants and young children between 6-24 months. Study Design: A case control study. Participants: Children aged between 6-24 months, admitted or attended OPD in paediatric wards of 3 hospitals attached to JJM medical college. Intervention: No intervention was involved in this study. Outcomes: This study findings revealed the status of iron deficiency anaemia among 6-24 months children and also its contributing factor which influence the indication. Results: In our study 50% were anaemic, 50% were not anaemic, in that, 27.1% had moderate anaemia, 22.9% had severe anaemia. Compared to early initiation of breastfeeding at birth, delayed initiation of breastfeeding was associated with higher chances of IDA. Those children who were not exclusively breastfed for first 6 months had higher chances of IDA. Initiation of top milk before 12 months was associated with higher chances of IDA especially before 6 months. Conclusion: Top feeding, faulty weaning and feeding practices are the main contributing factors of anaemia among children under 2 years.
Fabrication of a 3D combinatorial fibrous-porous scaffold for neural tissue engineering applications

Field: Engineering (Physical Sciences)

The ability of tissue engineered scaffolds to modulate the response of neural stem cells (e.g. adhesion, proliferation and differentiation) is boosting the unlocking of advanced therapeutic strategies capable of attenuating the effects of traumatic pathologies like spinal cord injury [1]. From the wide range of reported scaffolding concepts, it has been consistently demonstrated that nanofibrous networks and graphene-based porous systems are proficient for guiding neurite outgrowth and inducing specific differentiation patterns, respectively [2].
