Simulation of low-pressure rf plasma treatment of ultrahigh molecular weight polyethylene

Methods of molecular dynamic simulation of the bombardment of polymeric materials by low-energy (up to 100 eV) ions generated in radio-frequency low-pressure (13.3-133 Pa) plasma are discussed. A model of RF plasma treatment of ultrahigh molecular weight polyethylene (UHMWPE) has been developed. It has been established that the bombardment of UHMWPE by argon ions initiates the fast rotation of the polymer chains, and the rupture of intramolecular bonds.
RHEUMATOLOGY: MADE IN INDIA (Camps, COPCORD, HLA, Ayurveda, HAQ, WOMAC and Drug Trials)

This coveted oration describes my clinical and research career. The focus is on ‘Indian-ness’ and contributions to Indian Rheumatology. Methods: This oration will focus on clinical profile, camps, HAQ, Community oriented program for control of rheumatic diseases (COPCORD) Bhigwan, Ayurveda, drug trials, ANA, HLA, BJD, New Millennium Indian Technology Leadership Initiative (NMITLI), MAI, database & CRD. Results: The clinical profile of Indian arthritides is different and Caucasian population based classification criteria do not suffice. Comparative data from free arthritis camps is presented. Validated versions of HAQ and WOMAC suitable for Indian use were developed and are presented. The maiden Indian WHO COPCORD, an ongoing rural population program in Bhigwan (Pune), has provided statistics on prevalence, incidence, risk factors. The Bhigwan model, unlike any other COPCORD, provides free clinical services. The Bhigwan longitudinal observational seven year data from RA patients (unpublished)showed that (i)regular DMARD use had lower HAQ scores(better functional ability)(ii)chloroquin was safe(iii)steroids had higher HAQ scores. The HLA DR. profile in RA, both from Bhigwan and hospital referrals, was remarkably different. We have demonstrated the efficacy and safety of certain standardized Ayurvedic drugs in RA and OA knees through several controlled randomized drug trials; one of these drugs is now marketed worldwide. These trials also showed an unprecedented robust placebo response. A multicentric NMITLI arthritis program, funded by Government of India, has been launched to identify evidence based Ayurvedic medicinal plants and will be co-ordinated from CRD, Pune. The Bone and Joint Decade (BJD) 2000-2010 India program, also run from CRD, has launched several national research programs. Conclusion: As clinicians, we can do significant research, especially pertaining to community needs. Arthritis camps are useful. But we also need population studies such the WHO COPCORD Bhigwan. BJD has begun to measure the national disease burden. Ayurvedic medicines can treat arthritis and need further scientific exploration. Rheumatology needs to be recognized both as a specialty and a research area.

Shifting the Paradigm of Coping with Nyx on the Moon — a Ground-Penetrating Radar Case

Introduction: Radar has played a key role in characterizing the properties and geology of the Moon, from ground-based [1] to bi-static [2], sounders [3] and a ground-penetrating radar [4]. Currently, a higher level of fidelity in data is needed to fully characterize and interpret the lunar geologic and to be able to exploit its resources. Radar will continue to be a key tool in this effort, and this belief is supported by the needs outlined in the Lunar Exploration Road Map and the Lunar Knowledge Gaps document. Detection and mapping of polar volatiles, of pyroclastic deposits and regolith stratigraphy, and of lunar lava tubes are among the primary science cases for ground-penetrating radar instruments. Aside from the ice deposits expected in and around the permanently shaded areas near the poles, primary science targets are distributed around the Moon in the equatorial and tropical latitudinal bands. MARGE: We are currently developing a groundpenetrating radar (GPR) instrument that is an intrinsic part of a compact, autonomous rover. The size of the Multi-static Autonomous Roving Ground-penetratingradar Explorer (MARGE) is driven by the size of the GPR antenna, which is approximately 50×50 cm and capable of transmitting and receiving an ultra-wide frequency band from 120 MHz to 2 GHz. This operational band permits penetrations of up to ~20 m while providing depth resolution of for typical lunar regolith and rock dielectric constants [5] and a dynamic range of 120 dB; see Figure 1 for the link analysis.
Does nominal lineup size matter

The minimum number of distractors required in a lineup varies across jurisdictions. However, available data do not support the importance of nominal lineup size as a criterion of lineup fairness. Two staged-crime experiments were conducted in which the central manipulation was lineup size. The importance of nominal lineup size relative to other aspects of lineup procedure is discussed
A GENERALIZED FORCE AND CHIP FLOW MODEL FOR OBLIQUE CUTTING AND VARYING UNDEFORMED CHIP CROSSSECTIONS

Simple cutting force models are well suited for orthogonal cutting. However, industrial processes often use oblique cutting with complicated cutting edge shapes, where simple cutting force models underestimate the forces. The new cutting force model is based on an existing model for restricted chip motion, but generic cutting edge and rake face shapes and arbitrary process kinematics are accepted to calculate the chip flow direction. The model is able to predict the force changes in the beginning of a turning process, when a tool with large nose radius enters the workpiece, and the chip movement in drilling.
In-situ measurement of indium segregation in InAs/GaAs submonolayer quantum dots

Reflection high-energy electron diffraction was used to determine In segregation during the growth of InAs/GaAs submonolayer quantum dots by molecular beam epitaxy. The segregation coefficient R was estimated for the usual growth conditions, starting from a c4 × 4 reconstruction of the GaAs(001) surface, as well as for another set of very different growth parameters, yielding an initial 2 × 4 surface reconstruction that might provide quantum dots of better quality.
Application of the Welfare Quality ® animal welfare assessment system in Finnish pig production, part I: Identification of principal components

The Welfare Quality® (WQ) on-farm welfare assessment protocols for fattening pigs (n = 95 farms) and sows, as well as suckling piglets (n = 103 farms), were applied on Finnish farms. In order to identify distinct types of welfare problems (WPTs) Principal Component Analysis (PCA) was applied to the pooled animal-based items within both categories of animals. Measures describing suckling piglets did not contribute to the WPTs. The main WPTs (seemingly) reflected fighting in fattening pigs and lack of bedding in both fattening pigs and sows. The results imply that WQ includes biologically plausible shortlists of animal-based measures with decent to good internal consistency describing distinct types of welfare problems in growing pigs and in sows. The 20 descriptors of Qualitative Behavioural Assessment were analysed similarly to identify distinct mood types, which were named active positive, passive positive and passive positive behaviours. The different mood types had close to identical build-up in both fattening pigs and in sows and suckling piglets.
Alluvial Morphodynamics of Bedrock Reaches Transporting Mixed‐Size Sand. Laboratory Experiments

Research on the morphodynamics of bedrock rivers has primarily focused on bedrock incision, and little is known about the alluvial morphodynamics of rivers with exposed bedrock surfaces. More specifically, there is a lack of information on the morphodynamics of low slope bedrock reaches due to the recent recognition of such systems. Here, we present the results of laboratory experiments specifically designed to gain novel insight into flow resistances, flow hydrodynamics, and sediment transport processes in equilibrium partially exposed bedrock reaches transporting nonuniform sand as bed material in low slope areas. The experiments show that (1) downstream of a stable alluvial‐bedrock transition flow depth decreases in the streamwise direction, (2) bedform amplitude may decrease in the streamwise direction, and (3) stable patterns of downstream fining may form. Given the bedrock geometry, the water surface elevation at downstream boundary and the characteristics of the bedform regime in an alluvial channel subject to the same flow rate and sediment supply at equilibrium control bedform characteristics and sediment sorting patterns in the bedrock reach. When this distance is significantly smaller than the alluvial equilibrium flow depth or when the alluvial equilibrium bedform regime is close to the dune‐antidune transition, bedforms in the bedrock reach are closer to the dune‐antidune transition than at alluvial equilibrium with a consequent reduction in bedform amplitude. If the distance between the water level at the downstream boundary and the bedrock surface is close to the alluvial equilibrium flow depth and the alluvial equilibrium bedforms are well in the dune regime, a stable pattern of downstream fining can be expected. The comparisons between experimental and modeled sediment transport rates and equilibrium grain size distributions of the sediment further show that surface‐based bedload transport models derived for alluvial systems reasonably predict equilibrium sediment transport rates and bed surface size distributions in bedrock reaches if the presence of exposed bedrock is accounted for in terms of alluvial cover fraction.
Otogenic brain abscess: A rising trend of cerebellar abscess an institutional study

Chronic inflammation of the middle ear is the most frequent cause of otogenic complications. Meningitis is the most frequent intracranial complications, followed by otogenic brain abscess in neglected otitis media. Although temporal lobe abscesses are more common than cerebellar abscesses, the converse was found to be true in our series of 17 cases. 16 cases of cerebellar abscess and 1 case of temporal lobe abscess were reported as a complication of chronic otitis media (COM). In our group of patients, otogenic brain abscesses were more frequent in male patients of age group 5–20 years with mean age of 14 years. Diagnostic procedure included history, clinical, otorhinolaryngological examination, audiological, microbiological, neurological, ophthalmological, and radiological examinations. The treatment included primary neurosurgical approach (abscess drainage) followed by radical otosurgical treatment.
Development of a numerical model for hydrogen bubble generation, dynamics and trapping during solidification of aluminium alloys through Eulerian-Lagrangian framework

ABSTRACT In the present study, the authors developed a new numerical model to predict the bulk fluid flow, heat transfer, hydrogen species transfer with the hydrogen bubble generation, dynamics and trapping during solidification of aluminium through the continuum theory with Lagrangian bubble dynamics. The generated bubble size is assumed to be dependent on the microstructure. The bubble drag force is newly proposed in the Euler-Lagrange framework. In a model casting system, almost all generated hydrogen bubbles are trapped into a solidified aluminium. However, the hydrogen bubbles are capable of generating in the melt phase and detaching from the mushy zone when the initial hydrogen concentration is high. In this case, the hydrogen bubbles move upward due to buoyancy and this movement is slightly affected by the surrounding melt flow.
Analysis of seismic safety assessment procedures for joint development of coal deposits

The safety of mining and exploitation operations is an important factor that allows accident-free mining of mineral raw materials. To achieve this goal, the companies take various measures to reduce hazardous factors, which include blasting and distribution of seismic explosion waves as the phenomenon under consideration. The initial calculation for the reduction of hazardous factors is based on a specially designed procedure. Currently, there are no approved standard methods that could relate to impact of seismic explosion waves on the mounting of mine openings. Various researchers have developed procedures that have certain advantages and disadvantages. This paper presents the methods to assess seismic explosion impact during joint development of coal deposits, which are commonly applied in Russia. It shows the analysis of proposed methods and directions for further improvement of calculations of safe parameters of seismic explosion waves to mine openings.
Development of Bio-composite Reinforced by Sugarcane Fibres

Received: 14 March 2018 Accepted: 3 December 2018 The aim of the present study is to develop a multifunctional sugarcane fibres reinforced epoxy porous composite combining good acoustic and mechanical properties. The study of the bagasse fibres geometry has shown that fibres’ length and diameter distribution can be fitted by lognormal laws. Composites manufactured by thermo-compression process with an epoxy matrix were characterized using an experimental design whose parameters were the diameter of the fibres (between 0.5 and 4 mm) and their mass ratio (between 40 and 70 %). The study of acoustic properties showed that the sound absorption increases with the diameter of the fibres, while decreasing with their mass proportion, over a frequency range between 500 and 1000 Hz. Mechanical characterisation by bending tests, has shown a fragile behaviour, with deviations of stiffness and maximum stress around 36 %. The stereo-correlation image analysis confirmed the heterogeneity of the strain fields throughout the thickness, in relation to the fracture observation.
Il modello nutrizionale mediterraneo nelle malattie reumatiche infiammatorie The mediterranean diet model in inflammatory rheumatic diseases

SUMMARY The Mediterranean diet is based on a pattern of eating that’s closely tied to the Mediterranean region, which includes Greece and southern Italy. Essentially, the traditional diet emphasizes foods from plant sources, limited meat consumption, small amounts of wine and olive oil as the main fat source. The beneficial effects of the Mediterranean diet has been proven not only to cardiovascular diseases but also for diabetes, obesity, arthritis and cancer. Its anti-inflammatory and protective properties are linked to the large presence of ω-3 polyunsaturated fatty acids, vitamins, but especially to the constituents of extra virgin olive oil: oleic acid, phenolic compounds olecanthal, a new recently discovered molecule, with natural anti-inflammatory properties. It has been shown that the Mediterranean diet can reduce disease activity, pain and stiffness in patients with inflammatory arthritis and may thus constitute a valuable support for patients suffering from these diseases.

Microstructure and mechanical behaviour of additive manufactured Ti–6Al–4V parts under tension

Metal-based additive manufacturing technologies using electron or laser beams as a heat source for melting a metal powder or wire have been the subject of keen interest in recent years. At present paper a comparative analysis of the microstructure, strain response during tensile test and mechanical properties of Ti–6Al–4V samples produced by selective laser melting, electron beam melting or electron beam free-form fabrication were performed. A microstructural study using transmission electron microscopy revealed columnar prior β grains transformed into a lamellar α-morphology in the samples. According to X-ray diffraction study, the volume fractions of the β-Ti phase in the samples were equal to 2, 4 and 6 % respectively. It has been shown that the Vickers microhardness of SLM and EBM Ti–6Al–4V samples was similar (~5.4 GPa) while the hardness of EBF3 parts was significantly lower (4.5 GPa). The uniaxial stress-strain response of the Ti–6Al–4V samples fabricated by different additive manufacturing technologies were compared. Crystallographic (dislocation motion) and non-crystallographic (shear banding) deformation mechanisms of the loaded samples were studied by scanning electron microscopy and optical profilometry.
Strategic electromagnetic geophysical prospecting across a belt - an example over the Albany Fraser Orogen

Summary Nickel exploration routinely utilises electromagnetic (EM) techniques as a direct detection tool. Independence Group is currently exploring a large tenement holding in the Albany Fraser Orogen in Western Australia that contains its flagship Nova magmatic nickel-copper-cobalt deposit. As a first-pass exploration stage, large-scale high-resolution airborne EM is being flown over the project using the Spectrem system. Interpreted discrete basement conductors are then followed up with ground EM surveys. In areas of conductive regolith cover identified from the airborne EM surveys, other datasets are used to determine if subsequent EM is warranted. Such methods include regional aircore geochemistry and/or through favourable lithostructural settings interpreted from high resolution potential field datasets. This program of regional data collection is nearly complete, and a follow-up drilling program is starting in earnest this year. This paper includes a couple of examples of the geophysical targets drill tested to date.
Transmittance of high-density polyethylene from 0.1 THz to 15 THz

High-density Polyethylene (HDPE), with a density above 0.95 g/cm3, has been widely used in terahertz systems. The advantages of low absorption loss, low refractive index and high rigidity make HDPE an ideal material for cryostat window, focus lens and substrate. HDPE can be machined easily and be used as a substrate material for components such as metal mesh filters and polarizers. What’s more, it is quite inert and can be used at cryogenic temperatures. On account of these applications, we need to characterize the dielectric property of HDPE precisely in a wide frequency range. In this paper, we present the transmittance measurements of a 2 mm thick HDPE sheet from 0.1 THz to 15 THz. Three kinds of measurement methods are employed to cover the whole frequency range. A vector network analyzer (VNA) combined with a quasi-optical transmissometer has been used to measure the transmittance and dielectric constant of HDPE from 0.16 THz to 0.18 THz at 300 K and 4 K. A Time Domain Spectrometer (TDS) is employed to cover the frequency range from 0.2 THz to 3 THz since the VNA can’t work upon 1 THz. A Fourier Transform Spectroscopy (FTS) has been used for the measurement from 3 THz to 15 THz since the TDS can’t achieve broad band and fast scan speed. The measured transmittance of HDPE is nearly 0.93 below 1 THz and decrease to 0.3 when the frequency increase to 15 THz. A rather elusive absorption band at 2.2 THz has also been observed. The dielectric constant of HDPE has been measured by VNA and TDS, showing a frequency independency from 0.1 THz to 3 THz.
Emerging nutrient management databases and networks of networks will have broad applicability in future machine learning and artificial intelligence applications in soil and water conservation

Nutrient management, including management of nitrogen (N) inputs, was a key part of the Green Revolution, which increased global agricultural production and helped feed the world in the latter half of the twentieth century. While N is often applied to increase yields, and is indeed essential to meet the increased production demand that inevitably follows population growth, an extensive number of studies from regions throughout the globe have reported negative impacts related to N losses to the environment (Smith et al. 2018; Follett and Walker 1989; Hey 2002; Hey et al. 2005; Greenhalch and Sauer 2003; Delgado and Follett 2010; Juergens-Gschwind 1989; Dubrovsky et al. 2010; Glebe 2006), particularly when N was applied at excessive rates, allowing much of the unused N to quickly escape agroecosystems via atmospheric, surface runoff, and/or leaching pathways. Among the negative effects reported by these studies were contributions to the development of hypoxic zones and algae blooms; direct and indirect losses of nitrous oxide (N2O), a greenhouse gas (GHG) that exacerbates a changing climate; nitrate (NO3−) leaching losses that can negatively impact groundwater and surface water quality; and other negative environmental impacts. There is widespread agreement in the scientific community that emissions of N2O are…
