description: Innovative digital health technologies present an opportunity to create affordable, sustainable, and scalable monitoring technology to expand access to care in low-income and middle-income countries. This study aims to develop computer algorithms that automatically estimate respiratory rate from videos of infants captured using a smartphone. Based on the gaps identified in previous research, this project focuses on using smartphone video data taken in environments containing lighting variations, with handheld videos containing movement artifacts. For this study, 57 videos were captured from 39 infants <3 months of age at Kamuzu Central Hospital in Malawi, East Africa. Five small paper stickers were applied to the infant’s skin to facilitate respiratory rate tracking. Implemented in MATLAB, algorithms were developed to identify stickers on the infants’skin, track sticker movement coming from respiratory rate, and estimate breath count. This study indicated that non-contact respiratory rate monitoring for infants could be an effective method of accurately estimating respiratory rate using smartphone videos with lighting variations and movement artifacts. However, given the high accuracy and reliability required for effective monitoring tools, the current methods developed require further development to be successful. Overall, this study's results align with previous research as lighting variation and movement artifacts presented as major technical challenges to achieving high accuracy of respiratory rate estimation.

description: We first present an overview of the Schwarzschild vacuum spacetime within general relativity, with particular emphasis on the role of scalar polynomial invariants and the null frame approach (and the related Cartan invariants), that justifies the conventional interpretation of the Schwarzschild geometry as a black hole spacetime admitting a horizon (at $r=2M$ in Schwarzschild coordinates) shielding a singular point at the origin. We then consider static spherical symmetric vacuum teleparallel spacetimes in which the torsion characterizes the geometry, and the scalar invariants of interest are those constructed from the torsion and its (covariant) derivatives. We investigate the Schwarzschild-like spacetime in the teleparallel equivalent of general relativity and find that the torsion scalar invariants (and, in particular, the scalar $T$) diverge at the putative ``Schwarzschild'' horizon. In this sense the resulting spacetime is {\em not} a black hole spacetime. We then briefly consider the Kerr-like solution in the teleparallel equivalent of general relativity and obtain a similar result. Finally, we investigate static spherically symmetric vacuum spacetimes within the more general $F(T)$ teleparallel gravity and show that if a such a geometry admits a horizon, then the torsion scalar $T$ necessarily diverges there; consequently in this sense such a geometry also does {\em not} represent a black hole.

description: Abstract: The panacea to poverty situation in Nigeria is hinge on the significant roles played by huge amount of money allocated to SMEs. Therefore, competitive prices, quality of product and efficient services are provided among industries whether public, private, big, small, simple or complex in operations. In Nigeria, it is projected to be seedbed of novelties, inventions, employment to alleviate poverty. Over the years, these important components are growing exponentially in the midst of huge SMEs financing in Nigeria, yet poverty indices keep rising. It is on this backdrop that this paper investigate  the asymmetric connection amid SMEs financing and situations of Poverty in Nigeria evidence Non-linear Autoregressive Distributive Lag (NARDL) model using annual data spanning from (1992-2023). The asymmetric test discovered that co-integrating association exist among the dependent and independent as a variables of concern. The NARDL result shown that the short and long-run of SMEs components have distorted effect on poverty reduction, but the marginal impact of Commercial Bank credit to SMEs and Government Funding to SMEs is statistically significant in reducing poverty in a short run looking at both the positive and the negative components of the explanatory variable, while aggregate capitalization and interest rate does not demonstrate marginal impact on poverty reduction. The long run result uncovered that Commercial bank credit, government Funding negate the estimated sign and the effect is  statistically insignificant, it was on the aggregate capitalization that reveals the effect on reducing poverty, but the impact is not statistically significant. The study recommended that; Government should establish SMEs Bank that will aimed at making loans available to SMEs as low as 3-4% interest rate to ameliorate the adverse financial challenges bedeviling the sector because most entrepreneurs relied on personal savings and family for funds.

description: The high temperatures and reaction rates reached during hydrogen (or hydrogen enriched methane) combustion is well known to lead to flame and combustion instabilities, with increased emissions and potential flashback as result. Air humidification, typically applied to the micro Gas Turbines (mGTs) to increase electric efficiency by recovering additional waste heat from the flue gases, is proven to lead to reduced reaction rates and temperatures in classical mGT combustors fired with classical fossil fuels. However, these were mainly considered before as negative side effects. Using these effects to stabilize hydrogen combustion in mGTs without having to redesign the combustor is a promising, but still to explore route. Hence, this work presents a feasibility study on the use of combustion air dilution using combustion air humidification to reduce temperature and flame speed of hydrogen combustion in a typical mGT combustion chamber (Turbec T100) using a combined 1D-3D approach. First, the 1D laminar flame benchmarking allows a predetermination of the necessary minimal water dilution of the combustion air to avoid flashback for several H2/CH4 blends (25/75, 50/50, 75/25 and 100/0 \%) at reduced cost. The predefined operating conditions are then tested and validated using high fidelity 3D Large Eddy Simulations of the actual combustor geometry of the T100 mGT. The 1D simulation results show that the combustion, at nominal operating conditions of the T100 (air mass flow rate of 800g/s, and a fuel consumption of 333kW, fuelled with different H2/CH4 blends) can indeed reach the same level of flame speed as pure methane combustion by humidifying the combustion air (using a water-to-air ratio of 3, 7, 12 and 23 \% respectively). Finally, the 3D simulation results show stable combustion for these predetermined levels of humidification. Similar temperature and reaction rate levels to those of pure methane combustion are reached in the combustor. Hence we can conclude that this dilution method allows to stabilize H2 combustion, and the 1D approach provides accurate and low cost predetermination of the operating parameter to avoid flashback apparition.
Associations of Light, Leisure-time Physical Activity with Short-term Episodic Memory in Middle-aged and Older Americans : Results from the MIDUS study
Creators: name: Huang, Olive
Publisher: name: The University of British Columbia

description: Physical activity (PA) is robustly linked to cognitive benefits (e.g., improved executive function, memory, and processing speed). Whereas most research has focused on moderate-tovigorous PA and its positive effects, light PA (LPA) has been relatively less investigated. Specifically, there is a paucity of longitudinal research on LPA and episodic memory, with existing literature mostly being experimental studies that are based on young adult samples. This study aimed to fill this gap by investigating the correlations between light, leisure-time PA and short-term episodic memory in middle-aged to older adults (N = 2288). Using a 9-year longitudinal dataset from the Midlife in the United States study (MIDUS), the present analyses examined the cross-sectional correlations between LPA and short-term episodic memory at baseline and follow-up, and the longitudinal correlation between baseline LPA and changes in short-term episodic memory. As predicted, LPA was correlated with cross-sectional episodic memory at both times; the correlations remained significant after controlling for sex and age. However, LPA was not longitudinally correlated with 9-year episodic memory changes, which may be due to the sample’s high education level or the restricted range of self-reported LPA values, with over half of the participants selecting the highest LPA level (“several times a week”). Although no longitudinal relationship was observed, our results suggest that higher LPA is associated with better cross-sectional episodic memory in middle-age to older adults. Strategies to incorporate LPA into health guidelines and cognitive interventions may have benefits for memory and buffering age-related cognitive decline. Future studies should examine mechanisms mediating the relationship between LPA and episodic memory, and would benefit from combining self-report assessments with behavioural measures (e.g., activity trackers)

description: Consider an M/M/1-type queue where joining attains a known reward, but a known waiting cost is paid per time unit spent queueing. In the 1960s, Naor showed that any arrival optimally joins the queue if its length is less than a known threshold. Yet acquiring knowledge of the queue length often brings an additional cost, e.g., website loading time or data roaming charge. Therefore, our model presents any arrival with three options: join blindly, balk blindly, or pay a known inspection cost to make the optimal joining decision by comparing the queue length to Naor's threshold. In a recent paper, Hassin and Roet-Green prove that a unique Nash equilibrium always exists and classify regions where the equilibrium probabilities are non-zero. We complement these findings with new closed-form expressions for the equilibrium probabilities in the majority of cases. Further, Hassin and Roet-Green show that minimizing inspection cost maximises social welfare. Envisaging a queue operator choosing where to invest, we compare the effects of lowering inspection cost and increasing the queue-joining reward on social welfare. We prove that the former dominates and that the latter can even have a detrimental effect on social welfare.

description: This research examines global issues concerning the development of mountain areas considered as territories difficult to manage. The case study area is part of the sub-region of High Alpine Steppes belonging to the Tunisian Ridge and reaching Tebessa Mountains in Algeria. The central question of this article is based on the analysis of the links between the representations produced by mountain landscapes and the construction of a border line that must meet the requirements of sustainable development. Eco-landscape determinants and the role of public authorities and population must be better defined so that the products of this space provide a better quality of life endowed with the alternatives of local and sustainable development. Our hypothesis is that the mountain areas of West Central Tunisia still have a real ecological potential little disturbed by a chimerical development, and can constitute assets for the territorial development of the area. The approach adopted by this work is a scoping audit based on the floristic richness and the monitoring of its spatiotemporal dynamics. The results of this research allowed us to draw rich conclusions; the phyto-ecology approach has shown a relative floristic richness that remains highly dependent on the climatic cycles and intervention of human action; this area must be considered as a priority of the public planning policies aimed at improving the quality of lives in these fragile zones in the context of sustainable development.
The Deterrence Effect : An Analysis of Preliminary Examinations by the International Criminal Court on the Severity of Civilian Atrocities
Creators: name: Angulo Molina, Danilo
Publisher: name: The University of British Columbia
Year: 2023

description: Despite preliminary examinations being the first stage of a four-stage intervention by the International Criminal Court (“the Court”), their deterrent effects remain largely unexamined. In this paper, I argue that, because a preliminary examination involves high-cost operations and comprehensive reports, it serves as a credible commitment signal to perpetrators that the Court is willing to take further and serious actions for the pursuit of justice. Thus, perpetrators are more likely to scale down the intensity of atrocities in order to avoid the escalation to a formal investigation, avoid being tried at the Court in the Hague, and protect their legitimacy. I test my argument by using time-series cross-section data for a period of 15 years, from 2004 to 2018, from 46 countries, including those with and without preliminary examinations. The findings support my hypothesis and theory, highlighting that preliminary examinations are significantly sufficient on their own to decrease the severity of civilian atrocities by approximately 15%. This study contributes to the literature on international criminal law and international tribunals by displaying the deterrence effect of preliminary examinations when analyzed independently instead of collectively with the other stages of intervention.

Modélisation

description: De nos jours la production de froid à température modérée est largement dominée par les machines à compression de vapeur utilisant des fluides de travail impactant le réchauffement climatique. Les machines Stirling, déjà utilisées en cryogénie, pourraient être une alternative pour cette application dans le domaine frigorifique. Dans ce but, nous travaillons sur une machine Stirling de type Beta. Nous avons modélisé cette machine à l'aide d'un modèle monodimensionnel développé dans le logiciel SAGE. Les composants du modèle sont un piston, un déplaceur, un échangeur chaud, un échangeur froid, un régénérateur, ainsi que les volumes de compression, détente et volume de rebond. Les différents composants sont reliés par des débits de gaz de travail et des flux thermiques. Pour le gaz de travail, les équations résolues dans le modèle sont les équations de conservation de la masse, de la quantité mouvement et de l'énergie ainsi que l'équation d'état du gaz. Le régime est harmonique. Des corrélations empiriques sont utilisées pour déterminer les coefficients d'échange thermique et de pertes de charge. Le modèle a été validé grâce aux résultats expérimentaux obtenus à l'aide du prototype FEMTO-60 développé au laboratoire. Il s'agit d'une machine de type Beta, de puissance frigorique de l'ordre de 450 W à 5$^{\circ}$C fonctionnant à l'azote comme gaz de travail, sous une pression de 15 à 20 bar, à une fréquence de rotation de 5 à 13 Hz. Le diamètre du piston est de 60 mm, le volume balayé est de 120 c\si{\cubic m}. Le régénérateur est constitué de grilles métalliques. Une analyse de sensibilité a ensuite été conduite en faisant varier les paramètres opérationnels et les paramètres géométriques de la machine. Pour les paramètres opérationnels, les effets du changement de gaz de travail, de pression, de fréquence de rotation ont été évalués. Pour les paramètres géométriques, les effets de la longueur du régénérateur, de sa porosité, des diamètres du piston et du déplaceur ainsi que le nombre et longueur des canaux des échangeurs ont été évalués. Grâce aux résultats de cette étude, une nouvelle conception de machine a été proposée sur le plan théorique. Elle permet d'augmenter la valeur de la puissance froide produite et du COP.

Improving ASR Contextual Biasing using Guided Attention Loss
Publisher: name: IEEE Signal Processing Society
Year: 2024

description: In this paper, we propose a Guided Attention (GA) auxiliary training loss, which improves the effectiveness and robustness of automatic speech recognition (ASR) contextual biasing without introducing additional parameters. A common challenge in previous literature is that the word error rate (WER) reduction brought by contextual biasing diminishes as the number of bias phrases increases. To address this challenge, we employ a GA loss as an additional training objective besides the Transducer loss. The proposed GA loss aims to teach the cross attention how to align bias phrases with text tokens or audio frames. Compared to studies with similar motivations, the proposed loss operates directly on the cross attention weights and is easier to implement. Through extensive experiments based on Conformer Transducer with Contextual Adapter, we demonstrate that the proposed method not only leads to a lower WER but also retains its effectiveness as the number of bias phrases increases. Specifically, the GA loss decreases the WER of rare vocabularies by up to 19.2% on LibriSpeech compared to the contextual biasing baseline, and up to 49.3% compared to a vanilla Transducer.
The Ethics of Human Resource Management: An Impossible Position

description: In the human resources (HR) field, there has been much written about the role of ethics. This may in part come from a perspective succinctly put by Kockan (2004) that HR has a special professional responsibility in balancing the needs of all stakeholders. This rather than the ethical perspective on issues is the starting point and focus of this chapter. Whilst the conceptual underpinnings of the theories of ethics go back centuries, less attention has been given to the evolution of Human Resource Management (HRM) as a framework and perspective which has emerged out of the industrial revolution. Specifically, the changing nature of the role particularly in the last 40 years and its positioning within organisations and for stakeholders, we argue this has a significant bearing on how ‘ethical’ decision-making involving HRM is made. As such, we explore the development of the HR role and function and by implication the changing focus of ethical decision-making. Using a taxonomy by Ekuma and Akobo (2015), we explore the notion of ethical decision-making and HRM from two established perspectives. The first is the strategic HRM approach and the second is the emerging Sustainable HRM perspective. Through these lenses, we hope to highlight the evolution and nature of HRM decision-making and ethics.

description: This thesis investigates how student-led research disrupted systemic barriers to gender equity in a high school technology academy serving a predominantly Latine student population in southeast Los Angeles County. Using Youth Participatory Action Research (YPAR) and Improvement Science, students led cycles of inquiry that identified cultural and structural obstacles to female participation in technology courses. They designed and implemented four interventions: an inclusive pre-recruitment event, a peer mentorship program (WIT Ambassadors), a student-led Women’s Council, and a leadership succession model known as She-Legacy. Data was collected through student-conducted empathy interviews and thematic analysis. All research activities were conducted under the supervision of credentialed educators, with student assent and adherence to school-based ethical protocols. Results include a significant increase in female enrollment and the development of sustainable, equity-centered institutional practices. This work demonstrates how student agency can drive systemic change in education.

description: Le rendement des panneaux photovoltaïques à base de cellules de silicium monocristallin est actuellement de l'ordre de 17 \% et celui-ci se dégrade dès que la température des cellules dépasse les 25°C. Dès les années 70, des capteurs mixtes (solaires thermiques et photovoltaïques) sont étudiés et mis au point afin d'exploiter la partie de l'énergie solaire non convertie en électricité. Depuis quelques années, de plus en plus d'études s'intéressent aux voies d'amélioration de ces capteurs. Nous pouvons citer entre autres le recours à la convection forcée de l'air, l'utilisation d'un fluide circulant dans un serpentin à l'arrière du panneau ou encore l'ajout d'ailettes mais celle qui nous intéresse est l'amélioration du coefficient d'échange entre l'air et l'arrière du panneau via l'utilisation d'ailettes génératrices de vortex. Une étude de 2017 de A. Khanjian a montré que l'utilisation d'ailettes génératrices de vortex permettait sous certaines conditions une amélioration du nombre de Nusselt de l'ordre de 40 \% pour les transferts de chaleur dans un conduit de section rectangulaire. Parallèlement, S. Chamoli a publié en 2018 une corrélation pour déterminer le Nusselt dans le chenal d'un capteur solaire thermique sur base de simulations dynamiques. Cette communication est réalisée dans le cadre d'un projet qui consiste à étudier, modéliser et monitorer les interactions entre une installation photovoltaïque améliorée et un bâtiment énergétiquement performant afin d'optimiser l'utilisation des ressources renouvelables en fonction des besoins de ce dernier. Nous avons développé et implémenté un modèle 1-D paramétrique d'un ensemble de panneaux photovoltaïques modifiés, nous permettant de pouvoir considérer l'ajout d'ailettes génératrices de vortex dans un canal de circulation de l'air à l'arrière des panneaux. Cet air peut être introduit dans le bâtiment au travers du système de ventilation. Pour les besoins de la simulation, nous avons considéré que le bâtiment était composé de 2 bureaux d'une personne utilisés uniquement du lundi au vendredi de 7h à 18h et équipés d'une ventilation double flux avec récupération de chaleur et by-pass. Nous limitons notre étude aux besoins en chaleur et en froid, assurés par une pompe à chaleur air-air et aux besoins électriques des équipements de bureau. L'article détaillera le résultat des simulations effectuées sur le système « bâtiment + capteurs » en mettant l'accent sur la sensibilité du modèle à différents paramètres tels que débit d'air, hauteur du chenal, inclinaison et orientation des panneaux, etc.

description: This study explores the economic value of Aleppo pine forests, a unique and threatened ecosystem in the border region of central Tunisia. These forests play a vital role in supporting small rural communities, but face increasing pressures and restrictions on their use. This research aims to assign a monetary value to forest conservation, considering the region's specific socio-economic context. Strategies for empowering local residents as key actors in developing sustainable cross-border initiatives are further investigated. Employing the contingent valuation method, a survey of 350 local residents and international users was conducted to assess their willigness to pay fo forest conservation efforts. Logistic regression analysis revealed that sociodemographic factors, such as monthly income and preferred payment method, significantly influence both and the likehood of participation. These findingd highlight the feasibility and importance of reconciling economic development with ecological sustainability in this critical region.

This approach offers a subjective framework that encourages each participant to contribute to the development of the educational environment. The key rationale for creating an environment that is conductive to learning is to allow the participants to step back from their field reality in order to reflect upon their work experience. The tools presented emphasize the exploration of participants' existing knowledge instead of focusing on providing new information. The key objective is to develop a method that assists the participants in undertaking reflection and self-analysis in order to deal with issues of needs assessment, problem solving and program planning.
Home : An intersection of acculturation and identity in Asian diasporic wellbeing

description: The idea of belongingness and home can often be an elusive one for diasporic folks. There is the oft-repeated and clichéd trope of existing in a liminal space, frustrated by being simultaneously both and neither. It being a cliché, though, does not stop it from being true. Compounding this struggle is the additional frustration of not knowing how to react when disaster strikes in one’s “heritage home” – does being away from that “home” automatically make one less? Does being away from the crisis take away one’s ability to claim to be? All of this comes down to the diaspora wondering about their obligations and belongingness. All of this is to say, for many in the Asian diaspora, one of the primary questions is, “Where is home?”
Tracing halo and intra-group light assembly in nearby groups and clusters

description: How are the extended and low-surface brightness halos of early-type galaxies built up, and which role does their environment play in their evolution? While resolved stellar populations from deep HST imaging are excellent tracers of nearby galaxy halos in pencil-beam fields, it is challenging to use them as tracers of extended haloes in galaxies or of the diffuse intracluster and intragroup light (IGL) at large spatial scales. Instead, at these distances, Planetary Nebulae (PNe) are a viable alternative. They are commonly used to trace spatial distribution and kinematics of the halo and intracluster light at distances of up to 100 megaparsecs. In my talk, I will focus on two non-isolated early-type galaxies: M49 in the Virgo Subcluster B and M105 in the Leo I Group. Since the Leo I group lies at just 10 Mpc distance, it is ideal for comparing results from resolved stellar populations with the homogeneous constraints over a much larger field of view from the PN populations and deep widefield photometry. In M105, we have — for the first time — established a direct link between the emergence of a metal-poor halo as traced by resolved red-giant branch stars and the presence of a PN population with a high specific frequency. This result confirms our earlier inferences, e.g. for M49 in the Virgo Subcluster B, that metal-poor halos and intra-group light are predominantly traced by PN populations with high specific frequencies.

description: The southern Mediterranean region, including Tunisia, faces significant challenges related to limited and irregular water resources, exacerbated by climate change. Agriculture, a crucial sector representing over 80% of water consumption in North Africa, is particularly vulnerable to water availability and quality. Meeting the increasing demand for food production, projected to double by 2050, further intensifies these challenges. To address water scarcity, especially in the next 30 years, it is crucial to implement effective water management solutions. In Tunisia, where water scarcity is a pressing issue, tapping into unconventional water sources like treated wastewater and desalinated water becomes imperative. These sources can play a pivotal role in bridging the gap between water availability and agricultural needs, ensuring a consistent water supply throughout the year. In response to these challenges, collaborative efforts within the framework of various Research and Innovation projects, have been undertaken. The objective is to develop innovative and context-specific solutions for the management of non-conventional water resources. Special attention was given to the technical, economic, social, and regulatory aspects, ensuring comprehensive solutions and effective outcomes. Low cost and energy efficient solutions for urban and industrial wastewater treatment have been developed. Demonstration pilots have been implemented in industrial and urban wastewater treatment plants. The treated wastewater has been successfully tested for field irrigation, yielding comparable results to traditional irrigation with drinking water, without adverse effects on plants or soil. Additionally, innovative desalination systems, incorporating nanofiltration and reverse osmosis, have been developed. These systems significantly reduce energy requirements and improve the recovery rate of desalinated water. Notably, these systems are powered by photovoltaic panels, aligning with sustainable energy practices. To ensure the adoption of wastewater and brackish water treatment systems, various measures have been implemented, with a focus on end-user acceptance. Replicability is emphasized, and recent examples demonstrate the successful implementation of these technological solutions. Efforts are made for the replicability of these technological solutions as evidenced by recent examples.

description: Analytical relations for the glass transition temperature, $T_g$, and the crystal melting temperature, $T_m$, are developed on the basis of nonaffine lattice dynamics. The proposed relations explain: (i) the seemingly universal factor of $\approx 2/3$ difference between glass transition temperature and melting temperature of the corresponding crystal, and (ii) the recent empirical discovery that both $T_g$ and $T_m$ are proportional to the liquid fragility $m$ divided by the thermal expansion coefficient $α$ of the solid.

description: The low rice production level in Africa is attributed to poor soil fertility despite the potential for rice cultivation in the inland valleys. This study was conducted to evaluate soil characteristics in some lowlands that have been continuously and intensively used for rice production for over two decades in southwestern Nigeria. Soil physical, chemical, and mineralogical properties, as well as phosphorus sorption characteristics, were assessed in soil samples collected from diagnostic horizons of profiles in six benchmark soils. The results show kaolinite, quartz, potassium(K)-feldspars, and mixed-layered smectite as the predominant minerals. The iron oxide fractions indicate that the soils are at varying degrees of development where the soils at the advanced stage of development are predominantly rich in kaolinite and quartz with a high concentration of total pedogenic iron oxide and generally low in soil fertility. Soil phosphorus buffering capacity is low and varies inversely with pH, confirming the deficiency of phosphorus at low pH. Short-range-order (SRO) iron (Fe) oxides show a strong affinity for phosphorus and this is stronger at lower soil horizons and mediated by some redoxomorphic reactions. The SRO iron oxide concentration has more influence on phosphorus retention in soils rather than the absolute concentration of iron oxides. The study concludes that SRO Fe oxides and soil pH are the major edaphic factors playing a prominent role in phosphorus retention and availability in the wetland soils rather than the clay minerals.

émissivité apparente
érosion éolienne du verre
détection de l'érosion par émissivité apparente.

description: En exploitation, les systèmes à énergie renouvelable sont soumis à des conditions climatiques variables occasionnant de nombreuses dégradations de leurs performances dans le temps. Parmi ces dégradations, l'érosion éolienne baisse l'efficacité énergétique de ces systèmes en modifiant ses propriétés dans le visible (absorbance, transmittance et réflectance). Un contrôle in situ des surfaces est possible, mais reste de proximité (observations visuelles, spectromètre portable, ...). On conçoit la difficulté d'un contrôle étendu dans le cas de centrales photovoltaïques ou de concentrateurs solaires constitués de plusieurs milliers d'unités (panneaux, miroirs).\\ Du fait de son faible coût, le verre est systématiquement utilisé dans les systèmes solaires comme support ou protection. Notre travail vise à quantifier la détectabilité de la dégradation par érosion éolienne au moyen de son émissivité apparente.\\ L'émissivité apparente est raccordée à l'émissivité spectrale des surfaces. Elle est obtenue sans contact au moyen d'une caméra thermique dans des conditions standards de thermographie. Bénéficiant des capacités d'imagerie infrarouge, il est possible de cartographier l'émissivité apparente de surfaces étendues et donc d'en imager les anomalies de surface incluant l'impact de l'érosion éolienne.\\ Dans ce but, des échantillons de verre sodocalcique ont été érodés, en utilisant une sableuse avec variation de l'intensité, des angles d'incidence et du temps de sablage. Une première étape consiste à déterminer le taux d'érosion pour chaque échantillon en utilisant une méthode d'imagerie basée sur le contraste noir et blanc. Des images d'échantillons ont été prises sous un microscope. Un logiciel de traitement d'image détermine le pourcentage d'érosion. Une seconde étape consiste à étudier la transmission du verre. Dans ce but, un dispositif a été assemblé en utilisant un pyranomètre encagé permettant de quantifier la transmittance du verre érodé. La troisième étape, consiste à caractériser les échantillons par émissivité apparente $\epsilon_{\Delta\lambda}$, en utilisant le banc expérimental développé par le CERTES. Cet indicateur est obtenu sans contact dans des conditions de contrôle strict des températures d'influence.\\ Nous constatons que l'émissivité apparente est un indicateur sensible à l'érosion et sa valeur croit en fonction de la surface érodée. Le seuil de détection d'érosion par émissivité apparente est d'environ 20 \% de surface érodée, par comparaison à une détection optique, il est de 50 \%. Nous concluons que l'émissivité apparente est un indicateur de dégradation potentiellement plus performant que les méthodes optiques.

description: The combined application of chemical fertilizers and organic material is a transitional approach toward more sustainable and productive farming. This study aimed to investigate the response of low chemical fertilizer rates and supplementing with organic materials on soil health and fruit quality. In plum orchard, combination of reduced chemical fertilizer rates (R80; R70; R60) with organic manures (F; V) at varying levels based the loss in nitrogen requirement and microbial inoculants (Bf; J) were studied over the conventional approach (R100) on soil health and fruit quality in a 2-year experiment. Soil analysis showed soil physico-chemical properties and enzymes activity with application of R70+V10+Bf. Compared to integrated treatments R100 saw highest availability of soil potassium and calcium. Application of R70+V10+J resulted in maximum improvement in fruit weight, TSS and soluble sugar content. Fruit set percentage was higher in treatment R70+V10+Bf. Fruit yield showed significant changes with treatments R70+V10+Bf and R70+V10+J having similar yield to R100. Our results suggest that by reducing the amount of chemical fertilizer by 30% and partially replacing it with organic materials had a positive effect on soil health without affecting the fruit production and quality.

description: Crystallography has been phenomenally successful at revealing the structural landscape of the protein world. However, crystallography alone cannot solve the fundamental issue of determining protein quaternary assemblies from crystal structures. Computational methods can come to the rescue here in determining plausible quaternary structure assemblies present in crystals. A few methods have made some progress in this context: PISA will determine one or more likely stable assemblies based on energetic estimations, EPPIC uses evolutionary information to determine whether pairwise interfaces are likely to be part of a quaternary assembly. There is, however, a need for methods that can produce an exhaustive analysis of all possible assemblies present in crystals, in order to aid in the structure interpretation of biological macromolecules.

We present here a novel method that can produce an exhaustive enumeration of assemblies in a given crystal by using a graph theoretical analysis of the crystal lattice. Using topological considerations we can enumerate all closed assemblies present in the crystal. Closed assemblies are those that exhibit point group symmetry, following the ideas introduced in the seminal 1965 paper of Monod, Wyman and Changeux. The different assemblies can then be scored with a mix of evolutionary and geometric scores at the pairwise interface level, and a prediction for the most likely assemblies that form in solution can be produced.

Additionally, the graph theoretical representation allows one to gain more insights into protein crystal lattices and how different lattices are related, for instance to determine whether different protein crystals share a similar lattice or to understand their relationship.

The method can greatly help in interpreting crystal structures, especially in cases where difficult-to-classify assemblies with apparent closed symmetries are present in the crystal. We hope that it can also aid in the general understanding of quaternary structure and of protein-protein interactions, both of which central to the understanding of protein function in vivo.
