description: The main objective of the study was to identify possible predictors of adoption of potatoes into a wheat-based cropping system. In this study nine explanatory variables were tested against two dependent variables (p= 0,15). The explanatory variables were gender, age, training, land ownership, soil type, household size, number of household members below the age of six (< 6) years, number of household members between 6 and 18 years of age and farming experience. The dependent variables tested were: crops adopted by farmers and household knowledge on soil fertility. Of all the nine explanatory variables tested against crops adopted, only two categorical variables, namely training (p=0,11) and land ownership (p=0,09), and one continuous variable, farming experience (p=0,02), were significant possible predictors. Of all the three variables (gender, age and training) tested against household knowledge on soil fertility, only gender emerged as a significant possible predictor (p=0,01). Farmers' years of experience and level of knowledge on soil fertility indicated a significant relationship (p=0,00) with a correlation coefficient of 0,25.

description: The objective of this study was to evaluate the role of alveolar macrophages (AM) in clearance of Pseudomonas aeruginosa in mice after intrapulmonary challenge. Alveolar macrophages were depleted by intranasal administration of liposome-encapsulated dichloromethylene diphosphonate (LDMDP). Control mice received an equal volume of phosphate buffered saline encapsulated liposomes (LPBS). 24 hours post-instillation of liposomes, a sublethal dose of P. aeruginosa was inoculated intranasally into mice. Lungs, spleen and liver were obtained from the two groups of mice at different time points; viable bacterial counts and histology were then analyzed. 78 - 88 % of alveolar macrophage depletion did not affect the survival rate of infected mice, or clearance of P. aeruginosa from the lung, spleen or liver, as compared to the control group. Recruitment of neutrophils in the lung was similar in both groups. As well, m vitro experiments have shown that freshly explanted alveolar macrophages were not competent to phagocytose unopsonzied P. aeruginosa, but were able to phagoeytose zymosan particles. Further studies were conducted to assess in situ phagocytic activities of alveolar macrophages. Three hours after the intranasal instillation of P. aeruginosa or other particles, bronchoalveolar lavage (BAL) was performed. Alveolar macrophage phagocytosis of zymosan particles (23%) and latex beads (27%) was much higher than that of P. aeruginosa (0-5%). Neutrophils were recruited to the lung in response to a high bacterial dose. These results suggest that the role of alveolar macrophages in the defense of the lung against P. aeruginosa challenge may not extensively involve their phagocytic activities.

description: We study free, covariant, quantum (Bose) fields that are associated with irreducible representations of the Poincaré group and localized in semi-infinite strings extending to spacelike infinity. Among these are fields that generate the irreducible representations of mass zero and infinite spin that are known to be incompatible with point-like localized fields. For the massive representation and the massless representations of finite helicity, all string-localized free fields can be written as an integral, along the string, of point-localized tensor or spinor fields. As a special case we discuss the string-localized vector fields associated with the point-like electromagnetic field and their relation to the axial gauge condition in the usual setting.

description: It is now well-established that mechanical equilibrium in athermal disordered solids gives rise to anisotropic spatial correlations of the coarse-grained stress field that decay in space as $1/r^d$, where $r$ is the distance from the origin, and $d$ denotes the spatial dimension. In this note we present a simple, geometry based argument for the scaling form of the emergent spatial correlations of the stress field in disordered solids.

description: Total knee arthroplasty (TKA) is a common surgical intervention for patients with advanced arthritis. The aim of this qualitative evidence synthesis was to systematically review the qualitative literature on patients’ experiences following primary TKA. Four electronic databases (PubMed, CINAHL, Cochrane and Embase) were searched from inception until October 2021. Pairs of reviewers independently screened search results for eligibility, analysed the quality of included studies and extracted data. We undertook a thematic synthesis and used an interpretive approach to identify recurring themes and draw a conclusion. Data were synthesised using thematic analysis and an interpretive approach was used to identify themes. Twenty-three studies exploring patients’ experiences following TKA were included. Five main themes emerged: (i) Experience of healthcare staff, (ii) Pain/Medications, (iii) Was it worth it? (iv) Social Support (v) Follow up. This review highlights the variability in patients’ experiences following TKA. Whether this experience detailed their pain, function, or encounter with healthcare staff or systems, patients reported a variety of both positive and negative sentiments. Each theme invites attention to an area in which healthcare can improve to enhance patients’ experiences. The importance of patient support, individualised rehabilitation and appropriate follow-up are highlighted. This paper reviews patients’ experiences after undergoing total knee arthroplasty (TKA)Patients need individualised programmes, made collaboratively with health care professionals, to maximise outcomes and improve motivation.Improved interdisciplinary dialogue and a more holistic approach would increase patients’ confidence in their care.Group-based communication classes may offer an improved method for patients to communicate their worries and learn from one another.

description: As P-I for the AHRC project Bass Culture (£533,032), Riley’s research involves locating, capturing and preserving memories, experiences and ephemera from three generations of musicians, music industry participants and audience members. The associated communities and networks have played a key role in transforming Britain into a multicultural society, yet their contributions have previously remained absent from the country’s cultural institutions. The output components draw on original interviews, new and archival imagery to inform both a large- scale multimedia, interdisciplinary exhibition at Ambika P3 (Bass Culture 70/50, 2018), and a collaboratively produced documentary film (Bass Culture, 2018). Included are a wide range of oral testimonies and previously unseen images (representing over 50 years of London-based content) that explore and make manifest reference points connecting the influence of British sound-system culture to modern and contemporary music, fashion and cultural forms today. Riley’s book chapter (2014) draws on his experiences as a black British musician of Jamaican heritage to contextualise the origins and emergence of black British music in the 1970s and 1980s against the socio-political backdrop of the era. Riley devised a methodology for working together with wide-ranging collaborators to break down and classify areas of interest, without disenfranchising the participants or co-researchers. In creating the online resource, the project’s researchers were able to apply key categories that helped guide navigation of the complex layers of material, cultural and economic activity underpinning key values that were shared within the community, while mapping the contribution for academia. The Bass Culture project successfully united academics, museums and the African Caribbean community in a series of projects that helped make visible the Jamaican contribution to British popular music and culture and lay the basis for popular music teaching that more accurately reflects that influence.

description: Sugar market is one of the most protected markets for agricultural products world wide. In almost every sugar producing country the sugar market is regulated in some way. With an increasing liberalization of agricultural trade in the "Millennium Round" of the WTO trade negotiations, the question of international competitiveness is of increasing importance. Based on empirical studies, in this article the competitiveness of sugar production in the most important sugar producing countries is analysed, including the whole production process from beet or cane production in the field to sugar processing in the factory. Special emphasis is focussed on the different location factors and their influence on competitiveness, so that finally, conclusions can be drawn on future development of the world sugar market and the single production locations. From the countries included in this study, at present only Brazil, Australia, Thailand and partly South Africa would be able to produce sugar under world market conditions. While Brazil and Australia profit from favourable natural, economical and political location factors, in Germany high opportunity costs as well as high environmental and social standards predominate the advantages of high efficiency in the sugar industry. In the United States partly disadvantageous climatic conditions together with high opportunity costs are responsible for the insufficient international competitiveness of sugar production. Low productivity in Thailand and South Africa is overbalanced by low wages as well as comparatively low environmental and social standards. Without standardised environmental and social regulations, a liberalization of the world market would force movements of sugar production from beet to cane areas with favourable natural, economical and political conditions.

Subjects: subject: Transportation Engineering

description: The primary goal of this thesis was the formulation of an integrated effort to collect, maintain, exchange, and evaluate engineering data on rock materials from a variety of information sources. The proposed rock evaluation program provides a data base of accumulated information by establishing procedures for characterizing rock, from specimen acquisition through indexing, classification and correlation studies of data, and the application of data for site selection, use tables, establishment of design parameters and alternatives, and maintenance of engineered facilities. The co-ordinated evaluation system detailed herein provides guidelines for implementation of an extensive system of data storage and retrieval to investigate the physico-mechanical aspects of both intact rock samples and in-situ rock masses. The exchange of disciplined information would be to the mutual benefit of practicing engineers and research scientists and would advance the study of rock behavior.
A Laser-based Dual-arm System for Precise Control of Collaborative Robots

description: Collaborative robots offer increased interaction capabilities at relatively low cost but in contrast to their industrial counterparts they inevitably lack precision. Moreover, in addition to the robots' own imperfect models, day-to-day operations entail various sources of errors that despite being small rapidly accumulate. This happens as tasks change and robots are re-programmed, often requiring time-consuming calibrations. These aspects strongly limit the application of collaborative robots in tasks demanding high precision (e.g. watch-making). We address this problem by relying on a dual-arm system with laser-based sensing to measure relative poses between objects of interest and compensate for pose errors coming from robot proprioception. Our approach leverages previous knowledge of object 3D models in combination with point cloud registration to efficiently extract relevant poses and compute corrective trajectories. This results in high-precision assembly behaviors. The approach is validated in a needle threading experiment, with a 150μm thread and a 300μm hole, and a USB insertion task using two 7-axis Panda robots.

description: The rich electronic and band structures of monolayered crystals distinguished from their layered bulk counterparts offer versatile physical/chemical properties and applications.1-5 Their fabrications, particularly the top-down "exfoliations", are successful promised by the weak Van der Waals force between monolayers.6-9 Differentially, un-zipping ultra-thin crystals (e.g. with only one layer of crystal plane) from non-layered structures is highly challenging due to the strong chemical bond between planes and atoms. Alterative finely controlled growth of these ultra-thin materials is not really successful. This work demonstrates how a technique can be used to unzip and disintegrate ultra-thin crystal plane (e.g. monolayered nanocrystals and nanosheets) from bulk non-layered structures (ZnO, alpha/belta-MnO2, TiO2, alpha-TiB2), and present how the basic optical properties changed to distinguish from their bulk phases. The work here gives a strong tool kit to various novel 2D non-layered nanomaterials, providing significant contributions to the family of two-dimensional materials, potentially paving the way for various practical applications.

description: To determine the criterion validity of the activPAL and ActiGraph for measuring steps and sitting/sedentary time, compared to observation, in people hospitalised following orthopaedic lower limb injury who were weight bearing (WB) (i.e., walking) or non-weight bearing (NWB) (i.e., hopping). Participants wore an activPAL and ActiGraph on the hip/thigh/unaffected (UA)/affected ankle (AA) while completing bouts of walking and sitting. Lin’s concordance correlation coefficient, Bland–Altman methods, and ratio of agreement were used to compare device-measured to observed (videoed) step count, sitting/sedentary time. In 42 participants, the ActiGraph demonstrated excellent concordance with the observed step count when worn on the ankle (LCC 0.91–0.92) compared to the hip (LCC 0.56) in participants that were WB. The ActiGraph AA achieved the highest concordance (LCC 0.71) with observed steps in participants NWB. The activPAL had poor concordance with observed steps, particularly at slow gait speeds, in participants that were WB (LCC 0.38–0.46), however was less influenced by gait speed and had good concordance in NWB participants (LCC 0.52–0.69). The activPAL (LCC 0.79–0.88) and ActiGraph UA (LCC 0.94) showed excellent concordance with observed sitting and sedentary time, respectively. The ActiGraph worn at the ankle provided the most valid measure of steps in people who are WB and NWB following orthopaedic injury, while the activPAL was best for measuring sitting time.Implications for rehabilitationTo accurately measure both steps and sitting time in people with lower limb orthopaedic injuries, a combination of activity monitors should be used (i.e., ActiGraph for steps, activPAL for sitting time).The ActiGraph device when worn on the ankle demonstrated the strongest agreement with observed step count in people who were weight bearing and non-weight bearing.Caution is needed when using thigh- or hip-worn devices in people who walk slowly. To accurately measure both steps and sitting time in people with lower limb orthopaedic injuries, a combination of activity monitors should be used (i.e., ActiGraph for steps, activPAL for sitting time).

description: Sugar beet production during the past 50 years has been characterised by remarkable progress in productivity. In this contribution the influence of the different production factors on productivity and value added growth is analysed by regarding input and output development as well as price changes, with special focus on the breeding progress. During this period there has been a shift in the importance of the different factors of production for productivity development. Until the 1980s sugar beet breeding mainly initiated remarkable yield and quality improvements as well as seed and especially labour savings. Since then, technical progress in plant protection, mechanisation and organization allowed considerable cost savings especially through labour savings and partly yield and quality growth. On the whole, the contribution of sugar beet breeding to value added growth during the last 30 years annually amounted to around 80 DM per hectare. During the last 20 years, based on beet price reductions, the seed related progress only amounted to around 20 DM per hectare, whereas cost savings and partly yield increases of 80 DM per hectare, based on chemical, mechanical and organizational technical progress, where considerably high. But, the remarkable benefit of various disease resistant varieties developed since the 1980s is not included here. As sugar beet cropping in large infested areas without the new resistant varieties would not be competitive any more, their benefit partly amounts to more than 2000 DM per hectare. With the technical optimisation of the production process for sugar beets being mostly completed now, further productivity progress is mostly expected from bio-technological progress.

description: This manuscript reports a stochastic dynamical scenario whose associated stationary probability density function is exactly a previously proposed one to adjust high-frequency traded volume distributions. This dynamical conjecture, physically connected to superstatiscs, which is intimately related with the current nonextensive statistical mechanics framework, is based on the idea of local fluctuations in the mean traded volume associated to financial markets agents herding behaviour. The corroboration of this mesoscopic model is done by modelising NASDAQ 1 and 2 minute stock market traded volume.

description: Precision Farming Technologies are being used by an increasing number of farmers in eastern Australia. The adoption of these technologies has resulted in a change in some agronomic practices. This project examines how the technologies are being used. Global Positioning Systems are being employed most readily with significant economic benefit particularly in setting up controlled traffic systems and the banding application of chemicals and fertilisers. Awareness of the benefits of controlled traffic has increased the use of GPS. A secondary reason for high accuracy GPS is to give the farmers greater labour options due to the shortage of experienced machine operators. Yield monitors and maps are mainly used for zoning fields with farmers being cautious about their value until better tools for analysing variance become available. Variable rate technology is not being used in a systematic manner at the present time.

description: Using a sample of red giant stars from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) Data Release 16, we infer the conditional distribution $p([α/\text{Fe}]\,|\,[\text{Fe/H}])$ in the Milky Way disk for the $α$-elements Mg, O, Si, S, and Ca. In each bin of [Fe/H] and Galactocentric radius $R$, we model $p([α/\text{Fe}])$ as a sum of two Gaussians, representing "low-$α$" and "high-$α$" populations with scale heights $z_1=0.45\,\text{kpc}$ and $z_2=0.95\,\text{kpc}$, respectively. By accounting for age-dependent and $z$-dependent selection effects in APOGEE, we infer the [$α$/Fe] distributions that would be found for a fair sample of long-lived stars covering all $z$. Near the Solar circle, this distribution is bimodal at sub-solar [Fe/H], with the low-$α$ and high-$α$ peaks clearly separated by a minimum at intermediate [$α$/Fe]. In agreement with previous results, we find that the high-$α$ population is more prominent at smaller $R$, lower [Fe/H], and larger $|z|$, and that the sequence separation is smaller for Si and Ca than for Mg, O, and S. We find significant intrinsic scatter in [$α$/Fe] at fixed [Fe/H] for both the low-$α$ and high-$α$ populations, typically $\sim 0.04$-dex. The means, dispersions, and relative amplitudes of this two-Gaussian description, and the dependence of these parameters on $R$, [Fe/H], and $α$-element, provide a quantitative target for chemical evolution models and a test for hydrodynamic simulations of disk galaxy formation. We argue that explaining the observed bimodality will probably require one or more sharp transitions in the disk's gas accretion, star formation, or outflow history in addition to radial mixing of stellar populations.

description: The market for organic products in Urumqi is at the beginning of its development. The objective of this paper is to gain knowledge about consumer's attitudes toward organic food in Urumqi which is the capital of Xinjiang Uygur Autonomous Region. The consumer's attitudes were collected by means of a face-to-face survey. Attitudes, purchasing frequency, supply satisfaction and beliefs about organic food were studied with a sample of 720 consumers. The data obtained from the survey were analyzed with univariate analysis, chi-square test, ANOVA and correlation analysis. About 44.9% of Urumqi consumers had never heard of organic food. Urumqi consumers who know organic food consider organically-grown products as very healthy, of good quality and tasty. Consumers are not very familiar with the supply of organic food in the market. One reason might be that there was very little advertisement about organic products. Some groups of consumers have more positive attitudes towards organic food, and they express an increased willingness to pay higher prices for these food. Therefore, marketing strategies for organic food should be targeted towards such groups. According to the research results, an important task for the producers will be to increase consumers' knowledge of what organic food is and how to differentiate it in the marketplace.

description: While passive surfaces offer numerous benefits for interaction in mixed reality, reliably detecting touch input solely from head-mounted cameras has been a long-standing challenge. Camera specifics, hand self-occlusion, and rapid movements of both head and fingers introduce considerable uncertainty about the exact location of touch events. Existing methods have thus not been capable of achieving the performance needed for robust interaction. In this paper, we present a real-time pipeline that detects touch input from all ten fingers on any physical surface, purely based on egocentric hand tracking. Our method TouchInsight comprises a neural network to predict the moment of a touch event, the finger making contact, and the touch location. TouchInsight represents locations through a bivariate Gaussian distribution to account for uncertainties due to sensing inaccuracies, which we resolve through contextual priors to accurately infer intended user input. We first evaluated our method offline and found that it locates input events with a mean error of 6.3 mm, and accurately detects touch events (F1=0.99) and identifies the finger used (F1=0.96). In an online evaluation, we then demonstrate the effectiveness of our approach for a core application of dexterous touch input: two-handed text entry. In our study, participants typed 37.0 words per minute with an uncorrected error rate of 2.9% on average.

description: The distribution of dark matter (DM) inside galaxies is not uniform. Near the central regions, its density is the highest. Then, it is logical to suppose that, inside galaxies, DM affects the physics of stars in central regions more than outer regions. Besides, current stellar evolutionary models did not consider DM effects in their assumptions. To consider the DM effects, at first one must estimate how much DM a star contains. The capture rate (CR) of DM particles by individual stars was investigated already in the literature. In this work, we discuss how CR can be affected when stars are members of binary star systems (BSS) (instead of studying them individually). When a star is a member of a BSS, its speed changes periodically due to the elliptical motion around its companion star. In this work, we investigated CR by BSSs in different BSS configurations. In the end, we discussed observational signatures that can be attributed to the DM effects in BSSs.

description: To summarize the available evidence for the delivery of synchronous virtual rehabilitation intervention services for preschoolers and to identify key factors associated with virtual intervention. Five databases were searched to identify peer-reviewed articles that assessed virtual interventions for preschoolers delivered by rehabilitation health professionals including physical therapists, occupational therapists, speech-language pathologists, audiologists, and their associated assistants. Relevant data regarding demographics, technology, mode of service delivery, timing, engagement, and measurement data were extracted, and charted. Data were then summarized quantitatively using frequency counts, and qualitatively using descriptive summaries. Sixteen studies were identified. Virtual interventions primarily targeted language difficulties or disorders, therefore most services were delivered by a speech-language pathologist or audiologist. Most interventions were delivered using Skype or Zoom on a weekly basis. Various technological features (e.g., phonology software, ‘e-helpers’) were included, and multiple activities (e.g., playdough, bubbles) and strategies were used to support engagement. This scoping review provides current knowledge about the delivery of virtual rehabilitation interventions for preschoolers to help guide best practices for clinicians. Future research could assess the validity of existing outcome measures in the virtual environment, and outline optimal session length and frequency for virtual preschool interventions. The COVID-19 pandemic has increased the need for effective, evidence-based virtual interventions.This study summarizes the available literature to support preschool rehabilitation clinicians in making decisions about virtual interventions.Data presented can inform clinical decisions about technology to use, session length and frequency for various disorders, and activities used to engage preschoolers in the virtual environment.

description: Zero-order (ZO) optimization is a powerful tool for dealing with realistic constraints. On the other hand, the gradient-tracking (GT) technique proved to be an efficient method for distributed optimization aiming to achieve consensus. However, it is a first-order (FO) method that requires knowledge of the gradient, which is not always possible in practice. In this work, we introduce a zero-order distributed optimization method based on a one-point estimate of the gradient tracking technique. We prove that this new technique converges with a single noisy function query at a time in the non-convex setting. We then establish a convergence rate of $O(\frac{1}{\sqrt[3]{K}})$ after a number of iterations K, which competes with that of $O(\frac{1}{\sqrt[4]{K}})$ of its centralized counterparts. Finally, a numerical example validates our theoretical results.

description: Consumers look for the highest affordable food quality, given their household budgets and perceptions of product quality. Such perception is however strictly related to culturally linked variables, and the importance attached to each component of the overall quality vary greatly among countries. Different perceptions lead to different purchase decisions. This concept is even clearer for the aspects of quality that can't be tested directly. Consumer goods may be divided into search, experience and credence goods, depending on when the consumer is capable of assessing their quality (before buying, after consuming or in the very long term). Most quality agro-food products, such as food with geographical indications (GIs) and low input food (LIFs), fall into the credence good category. The aim of this paper is to point out how much attention is currently paid in literature (both scientific and popular: articles, papers, reports, marketing studies etc.) to the evaluation of the perceived value of such credence goods attributes for the quality food sector, and which relationships are mainly explored. A special attention will be paid to the situation in China.

description: We report results from an investigation into consumer preferences for locally produced foods. Using a choice experiment we estimate willingness to pay for foods of a designated origin together with certification for Organic and GM free status. Our results indicate that there is a preference for locally produced food which is GM free, Organic and produced in the traditional season.

description: In this paper we discuss about properties of lattices and its application in theoretical and algorithmic number theory. This result of Minkowski regarding the lattices initiated the subject of Geometry of Numbers, which uses geometry to study the properties of algebraic numbers. It has application on various other fields of mathematics especially the study of Diophantine equations, analysis of functional analysis etc. This paper will review all the major developments that have occurred in the field of geometry of numbers. In this paper we shall first give a broad overview of the concept of lattice and then discuss about the geometrical properties it has and its applications.

description: Treatment beliefs play a crucial role for patient satisfaction and the treatment outcome in psychosomatic rehabilitation. The aim of this study was the development and the psychometric evaluation of an indication-specific questionnaire of beliefs about psychosomatic rehabilitation. The study was conducted at a psychosomatic rehabilitation clinic. The primary item list comprised k = 125 items. After a descriptive item analysis, we conducted an exploratory factor analysis. Furthermore, we tested reliability via McDonald’s Omega and construct validity by analyzing correlations of the scales with related constructs. Of the N = 264 participants, 50% were female and the mean age was 50.4 (SD = 9.8) years. K = 85 items were suitable for factor analysis, which resulted in k = 30 items constituting six scales, explaining of 57% the overall variance. The corrected item-total correlations were between r = 0.48 and r = 0.83. Internal consistency ranged from ω = 0.81 to ω = 0.86. The newly developed questionnaire assesses specific treatment beliefs about inpatient psychosomatic rehabilitation. The psychometric properties of the six scales are acceptable. Further studies should confirm the psychometric results, such as the factorial structure of the questionnaire.IMPLICATIONS FOR REHABILITATIONTreatment beliefs are known to play an important role for the adherence, therapy outcome and satisfaction in psychosomatic rehabilitation.We developed and tested a indication-specific questionnaire assessing treatment beliefs in psychosomatic rehabilitation.The questionnaire can be used to explore patient’s rehabilitation-related treatment beliefs, predict treatment outcomes, and to develop interventions attempting to modify these.

description: The globalization of trade in high quality foods is stimulating the development of international food standards and certification systems. Third-party certification as evolved as a means of ensuring that product information and signals on quality and safety attributes are sound and reliable. Certification can only provide credible market signals if it operates objectively and independently. This paper investigates the potential trade-off between certifiers' objectivity and the level of competition in the rapidly expanding market for third-party certification of quality foods. Based on a theoretical supply chain framework a nested panel analysis is applied to a set of accredited certifiers for the EurepGAP fruits and vegetables standard. Our results indicate that increasing economies of scale and market share in certification do matter.

description: Manipulating the strain induced poly-domains and phase transition in correlated oxide material are important for high performance devices fabrication. Though the electronic transport in the strained oxide film at macroscopic scales can be directly measured, the anisotropic electronic state and the controllable phase separation cross the insulator-to-metal transition within nanoscale size are still elusive. Here, we selected VO2 crystal film as a prototypical oxide and achieved the manipulation of anisotropy electronic phase separation via injecting He+ nanobeam into VO2 film at room temperature. In addition, this nanoscale phase separation was directly visualized by infrared near-field imaging measurements, showing the pronounced and unique cR-axis dependent anisotropy on VO2 surface. Our results offered new insights towards understanding the anisotropic nanoscale phase separation in strained metal oxide films.
