description: A house needs a third of its air exchanged every hour. Owners of houses built before 1960 relied on air leakage through the building envelope for indoor/outdoor air exchanges. And they could, because houses then were leaky enough and wind or temperature difference saw to the necessary air movement. In the 1960s, houses became more airtight, and some were heated electrically (they did not even need a chimney). In the 1970s with its oil crisis, houses became even more airtight. With little air leakage through the building envelope, a mechanical ventilation system is required for moisture and pollutant removal. So, the question now is: how does one ventilate optimally?
description: Dans une maison, le tiers de l'air doit être renouvelé chaque heure. Les propriétaires de maisons construites avant 1960 comptaient sur la transparence à l'air de l'enveloppe du bâtiment pour réaliser les échanges d'air entre l'intérieur et l'extérieur. Ils pouvaient le faire car les maisons étaient alors assez perméables, et le vent et les écarts de température assuraient les mouvements d'air nécessaires. Au cours des années 60, les maisons sont devenues plus étanches à l'air, et certaines étaient chauffées à l'électricité (elles n'avaient même pas besoin de cheminée). Avec la crise de l'énergie, pendant les années 70, cette tendance s'est encore accentuée. Lorsque l'enveloppe du bâtiment n'est guère perméable à l'air, il faut doter la maison d'un système de ventilation mécanique pour contrôler l'humidité et chasser les polluants. Alors, la question est la suivante : quelle est la meilleure méthode de ventilation?

description: We report measurements of a new type of magnetoresistance in Pt and Ta thin films. The spin accumulation created at the surfaces of the film by the spin Hall effect decreases in a magnetic field because of the Hanle effect, resulting in an increase of the electrical resistance as predicted by Dyakonov [PRL 99, 126601 (2007)]. The angular dependence of this magnetoresistance resembles the recently discovered spin Hall magnetoresistance in Pt/Y3Fe5O12 bilayers, although the presence of a ferromagnetic insulator is not required. We show that this Hanle magnetoresistance is an alternative, simple way to quantitatively study the coupling between charge and spin currents in metals with strong spin-orbit coupling.

description: Mammalian brain possesses ryanodine-sensitive Ca2+ channels, which in muscle cells mediate rapid Ca2+ release from intracellular stores during excitation-contraction coupling. Analysis of bovine brain ryanodine receptor (RyR) channels suggests specific expression of the cardiac-muscle RyR isoform in mammalian brain. Localization using cardiac-muscle RyR-specific antibodies and antisense RNA revealed that brain RyRs were present in dendrites, cell bodies and terminals of rat forebrain, and highly enriched in the hippocampus. Activity of skeletal-muscle RyR channels is coupled to sarcolemmal voltage sensors, in contrast with cardiac-muscle RyR channels, which are known to be Ca(2+)-induced Ca(2+)-release channels. Thus Ca(2+)-induced Ca2+ release from intracellular stores mediated by brain RyR channels may be a major Ca(2+)-signalling pathway in specific regions of mammalian brain, and hence may play a fundamental role in neuronal Ca2+ homoeostasis.

description: In many ways the 1995 National Building Code (NBC) parallels and complements the CSA standard CAN/CSA-F326 in defining current approaches to mechanical ventilation in houses. Whereas F326 does not stipulate a maximum sound output, the NBC, for example, does: 53 decibels. The NBC gives details about the interrelationship of air intake and air output and the role various types of fans must play in houses that are either with or without a forced-air heating system. Houses without a forced-air heating system can also present problems in the even distribution of outdoor air.
description: Par bien des aspects, le Code national du bâtiment (CNB) de 1995 est à la fois parallèle et complémentaire à la norme F326 de la CSA qui définit les méthodes actuelles de ventilation mécanique des maisons. Alors que la norme F326 ne fixe pas de niveau sonore maximum, le CNB quant à lui en prescrit un de 53 décibels. Le CNB décrit en détail les relations entre les entrées et sorties d'air ainsi que le rôle que doivent jouer les différents types de ventilateurs dans les maisons qui sont équipées ou non de système de chauffage à air pulsé. La distribution d'air frais est parfois un problème pour les maisons qui ne sont pas chauffées par air pulsé.

description: Over 95% of the pyridoxal phosphate (PLP) in skeletal is bound to one protein, glycogen phosphorylase. This, and the fact that phosphorylase constitutes approx. 5% of the soluble protein in skeletal muscle, introduce the possibility that PLP might be used as a specific label to identify degradation intermediates of the enzyme. In this investigation, we have developed immunological methods, using a monoclonal antibody to PLP and polyclonal antibodies to phosphorylase, to detect degradation intermediates in vitro and in vivo. We have identified a family of degradation intermediates of glycogen phosphorylase in the high-speed-supernatant fraction of mouse skeletal muscle. These peptides react with both types of antibodies and are in the size and concentration range expected for degradation intermediates in a model in which the committed step is followed by rapid clearance of the products. Changes in amounts of degradation intermediates are examined in physiological or pathological conditions in which the rate of degradation of phosphorylase is altered.

description: Abstract

This research aims to investigate the relationship between company growth, leverage, profitability, and firm value. Specifically, it seeks to quantify how changes in leverage and profitability affect firm value, providing insights for managers and investors on strategies to enhance firm value through growth. The study employs a quantitative approach, utilizing financial data from a sample of companies over a specific period. The data is analyzed using statistical methods to determine the impact of leverage and profitability on firm value, measured by market capitalization or other relevant metrics. The research findings suggest that there is a significant relationship between company growth, leverage, profitability, and firm value. Higher levels of profitability and optimal leverage ratios are associated with increased firm value. The study also identifies specific strategies that companies can adopt to enhance their firm value through growth. The research is limited by the availability and quality of financial data, as well as the specific methodology employed. The findings may also be influenced by external factors such as market conditions and industry dynamics. This research contributes to the existing literature on firm value, growth, leverage, and profitability by providing empirical evidence of their interrelationships. The findings offer practical implications for managers and investors seeking to enhance firm value through strategic growth initiatives. The study's novelty lies in its quantitative analysis of the relationship between leverage, profitability, and firm value, offering new insights and empirical evidence to support decision-making in corporate finance and investment.

description: We applied implementation science frameworks to identify barriers and facilitators to veterans’ acceptance of pharmacogenomic testing (PGx), which was made available as a part of clinical care at 25 VA medical centers. We conducted 30 min interviews with veterans who accepted (n = 14), declined (n = 9), or were contemplating (n = 8) PGx testing. Six team members coded one transcript from each participant group to develop the codebook and finalize definitions. Three team members coded the remaining 28 transcripts and met regularly with the larger team to reach a consensus. The coders generated a matrix of implementation constructs by testing status to identify the similarities and differences between accepters, decliners, and contemplators. All groups understood the PGx testing procedures and possible benefits. In the decision-making, accepters prioritized the potential health benefits of PGx testing, such as reducing side effects or the number of medications. In contrast, decliners prioritized the possibilities of data breach or the negative impact on healthcare insurance or Veterans Affairs benefits. Contemplators desired to speak to a provider to learn more before making a decision. Efforts to improve the clarity of data security and the impact on benefits may improve veterans’ abilities to make more informed decisions about whether to undergo PGx testing.

description: Among patients with chronic cough (CC) in the 2012–2021 statewide OneFlorida Clinical Research Consortium database, we examined trends in cough medication (CM) prescribing prevalence over time in repeated cross-sectional analyses and identified distinct CM utilization trajectories using group-based trajectory modeling (GBTM) in a retrospective cohort study. Among eligible adults (≥18 years) without cancer/benign respiratory tumor diagnoses, we identified CC patients and non-CC patients with any cough-related diagnosis. In the GBTM analysis, we calculated the number of monthly prescriptions for any CMs (excluding gabapentinoids) during the 12 months from the first qualifying cough event to identify distinct utilization trajectories. From 2012 to 2021, benzonatate (9.6% to 26.1%), dextromethorphan (5.2% to 8.6%), and gabapentinoid (5.3% to 14.4%) use increased among CC patients, while opioid antitussive use increased from 2012 to 2015 and decreased thereafter (8.4% in 2012, 14.7% in 2015, 6.7% in 2021; all p < 0.001). Of 15,566 CC patients and 655,250 non-CC patients identified in the GBTM analysis, CC patients had substantial burdens of respiratory/non-respiratory comorbidities and healthcare service and concomitant medication use compared to non-CC patients. Among CC patients, GBTM identified three distinct CM utilization trajectories: (1) no CM use (n = 11,222; 72.1%); (2) declining CM use (n = 4105; 26.4%); and (3) chronic CM use (n = 239; 1.5%). CC patients in Florida had limited CM use with increasing trends in use of benzonatate, dextromethorphan, and gabapentinoids and a decreasing trend in opioid antitussive use. CC patients, particularly with chronic prescription CM use, experienced substantial disease burden.

description: The ability to simultaneously leverage multiple modes of sensor information is critical for perception of an automated vehicle's physical surroundings. Spatio-temporal alignment of registration of the incoming information is often a prerequisite to analyzing the fused data. The persistence and reliability of multi-modal registration is therefore the key to the stability of decision support systems ingesting the fused information. LiDAR-video systems like on those many driverless cars are a common example of where keeping the LiDAR and video channels registered to common physical features is important. We develop a deep learning method that takes multiple channels of heterogeneous data, to detect the misalignment of the LiDAR-video inputs. A number of variations were tested on the Ford LiDAR-video driving test data set and will be discussed. To the best of our knowledge the use of multi-modal deep convolutional neural networks for dynamic real-time LiDAR-video registration has not been presented.

description: The present study was designed to examine the interaction of the purified platelet glycoprotein IIb-IIIa complex (GP IIb-IIIa or integrin alpha IIb beta 3) and the individual subunits of the complex with immobilized fibrinogen. Although 125I-GP IIb-IIIa binding to fibrinogen immobilized on Sepharose was specific, this interaction exhibited properties distinct from those of reversible fibrinogen binding to platelets: 125I-GP IIb-IIIa binding appeared irreversible, but non-covalent, Ca(2+)-independent, and was inhibited only weakly, or not at all, by the anti-(GP IIb-IIIa) monoclonal antibodies 10E5 and 7E3 and synthetic peptides from known platelet-binding domains of fibrinogen. Reversibly dissociated GP IIb or GP IIIa subunits inhibited 125I-GP IIb-IIIa binding to immobilized fibrinogen and bound directly to the fibrinogen. However, these subunits did not bind to peptides derived from known platelet-binding domains within the fibrinogen alpha- and gamma-chains, although the GP IIb-IIIa complex did. These results show that the complexed form of full-length GP IIb and GP IIIa is required for binding to these synthetic peptides, but not necessarily for binding to immobilized fibrinogen. Thus GP IIb-IIIa can bind to immobilized fibrinogen by a distinct mechanism that appears to involve novel binding sites on each subunit of the GP IIb-IIIa complex and on fibrinogen.

description: The growing demand for sustainable development brings a series of information technologies to help agriculture production. Especially, the emergence of machine learning applications, a branch of artificial intelligence, has shown multiple breakthroughs which can enhance and revolutionize plant pathology approaches. In recent years, machine learning has been adopted for leaf disease classification in both academic research and industrial applications. Therefore, it is enormously beneficial for researchers, engineers, managers, and entrepreneurs to have a comprehensive view about the recent development of machine learning technologies and applications for leaf disease detection. This study will provide a survey in different aspects of the topic including data, techniques, and applications. The paper will start with publicly available datasets. After that, we summarize common machine learning techniques, including traditional (shallow) learning, deep learning, and augmented learning. Finally, we discuss related applications. This paper would provide useful resources for future study and application of machine learning for smart agriculture in general and leaf disease classification in particular.

description: A 43 kDa phospholipase C-activating protein has been purified previously from turkey erythrocytes and shown to express immunological properties expected of that of the Gq family of G-protein alpha-subunits [Waldo, Boyer, Morris and Harden (1991) J. Biol. Chem. 266, 14217-14225]. Internal amino acid sequence has now been obtained from this protein which shares 50-100% sequence identity with sequences encoded by mammalian G alpha 11 and G alpha q cDNAs. To identify the purified protein unambiguously, it was necessary to compare its amino acid sequence with the sequence encoded by avian G-protein alpha-subunit cDNA. As such, mouse G alpha q was used as a probe to screen turkey brain and fetal-turkey blood cDNA libraries. A full-length cDNA was identified that encodes avian G alpha 11, on the basis of its 96-98% amino acid identity with mammalian G alpha 11. All eight peptides sequenced from the turkey erythrocyte phospholipase C-activating protein are completely contained within the deduced amino acid sequence of the avian G alpha 11 cDNA. Expression of this cDNA in Sf9 cells by using a baculovirus expression system resulted in the production of a 43 kDa protein that reacts strongly with antisera to the Gq family of G-protein alpha-subunits and activated purified avian phospholipase C in an AlF4(-)-dependent manner. Taken together, these results unambiguously identify the protein purified from turkey erythrocytes, on the basis of its capacity to activate avian phospholipase C, as G alpha 11.

description: If the pressure in the air chamber behind the rainscreen is less than the pressure in front of it, rain is actually driven into the air chamber, which is, of course, undesirable. Through pressure equalization, this pressure difference is eliminated. A rainscreen wall has vent holes through which air can flow quickly to achieve pressure equalization. Two types of pressures -- static and dynamic -- have to be considered when calculating the size of the vent holes. Also, the pressure in an air chamber is not constant across the facade of a wall. That needs to be considered in their placement.
description: Si la pression dans la chambre à air derrière l'écran pare-pluie est inférieure à la pression qui sévit à l'extérieur du mur, la pluie est en réalité drainée dans la chambre à air, ce qui n'est, bien sûr, pas souhaitable. Un équilibrage des pressions permet d'éliminer ces différences. Un mur à écran pare-pluie est muni d'orifices d'aération au travers desquels l'air peut circuler rapidement pour permettre d'obtenir un équilibre des pressions. Il faut prendre en considération deux types de pressions - statique et dynamique - au moment du calcul de la taille des orifices d'aération. De plus, la pression dans une chambre à air n'est pas constante de part et d'autre de la façade. C'est aussi un élément qui doit être pris en compte pour l'emplacement de ces orifices.
Search for massive supersymmetric particles decaying to many jets using the ATLAS detector in $pp$ collisions at $\sqrt{s} = 8$ TeV

description: Results of a search for decays of massive particles to fully hadronic final states are presented. This search uses 20.3 fb$^{-1}$ of data collected by the ATLAS detector in $\sqrt{s} = 8$ TeV proton--proton collisions at the LHC. Signatures based on high jet multiplicities without requirements on the missing transverse momentum are used to search for $R$-parity-violating supersymmetric gluino pair production with subsequent decays to quarks. The analysis is performed using a requirement on the number of jets, in combination with separate requirements on the number of $b$-tagged jets, as well as a topological observable formed from the scalar sum of the mass values of large-radius jets in the event. Results are interpreted in the context of all possible branching ratios of direct gluino decays to various quark flavors. No significant deviation is observed from the expected Standard Model backgrounds estimated using jet-counting as well as data-driven templates of the total-jet-mass spectra. Gluino pair decays to ten or more quarks via intermediate neutralinos are excluded for a gluino with mass $m_{\tilde{g}} < 1$ TeV for a neutralino mass $m_{\tildeχ^0_1} = 500$ GeV. Direct gluino decays to six quarks are excluded for $m_{\tilde{g}} < 917$ GeV for light-flavor final states, and results for various flavor hypotheses are presented.

description: The influence of attractive boron impurities, embedded on a graphene sheet, on the phase diagrams of $^4$He and H$_2$ adsorbed on top was studied using the diffusion Monte Carlo method. The doping of graphene was made by distributing the boron atoms following the same pattern found in an experimentally synthesized substrate. Our results show that while the different incommensurate solid phases of both adsorbates remain largely unchanged after doping, the liquid/gas equations of state are significanty different from the ones on pristine graphene. Doping graphene produces new translationally invariant stable phases for $^4$He, depending on the concentration of boron impurities, but makes the H$_2$ ground state to remain solid. In addition, several new registered phases appear for both adsorbates.

description: A quasi-experimental study was conducted to evaluate the effectiveness of a pay-it-forward strategy for increasing influenza vaccination among children and older adults compared to a self-paid vaccination strategy in China. Pay-it-forward is an innovative community-engaged intervention in which participants receive a free influenza vaccination and are then asked if they would like to donate or create a message to support subsequent vaccinations. This economic evaluation used a decision-tree model to compare pay-it-forward to a standard of care arm in which patients had to pay for their own influenza vaccine. The analysis was performed from the healthcare provider perspective and costs were calculated with 2020 United States dollars. The time horizon was one year. In the base case analysis, pay-it-forward was more effective (111 vs 55 people vaccinated) but more costly than standard-of-care ($4477 vs $2725). Pay-it-forward spurred 96.4% (107/111) of individuals to voluntarily donate to support influenza vaccination for high-risk groups in China. Further costing and implementation research is needed to inform scale up.

description: When dealing with two interrelated parameters, here sound isolation and fire resistance, the challenge is not to gain in one at the expense of the other. That challenge is easily met with Group 0 fire stops, as long as the cavity between two sets of studs has an air gap of 25 mm or less. There is no flanking transmission of sound because the cavity is filled with insulation. With Group 1 fire stops, defined by the soft materials at the floor/wall junction, all flanking transmission of sound is absorbed by them. For Group 2 and Group 3 fire stops, flanking transmission occurs through the fire stops, more so with Group 3.
description: Lorsque l'on prend en considération deux paramètres interdépendants tels que l'isolement acoustique et la résistance au feu, le premier défi est de ne pas compromettre l'un au bénéfice de l'autre.

description: The actions of human recombinant stromelysins-1 and -2, collagenase, gelatinases A and B and matrilysin on neonatal human proteoglycan aggregates were examined. With the exception of gelatinase B, aggrecan was degraded extensively by most metalloproteinases studied, whereas link protein showed only limited proteolysis. Sequencing studies of modified link protein components revealed that stromelysins-1 and -2, gelatinases A and B and collagenase cleaved specifically between His16 and Ile17, and matrilysin, stromelysin-2 and gelatinase A cleaved between Leu25 and Leu26. Cleavage at the former bond generated a link protein component with the same N-terminus as that isolated from newborn human cartilage. Based on previously determined in situ cleavage sites it is evident that matrix metalloproteinases are not solely responsible for the accumulation of link protein degradation products in adult human cartilage, indicating that additional proteolytic agents are involved in the normal catabolism of human cartilage matrix.

description: The cDNA of the human GM2-activator protein was cloned into the expression vector pHX17. The plasmid encodes a fusion protein with a hexahistidine tail and a Factor Xa cleavage site at its N-terminus. The recombinant protein was purified from cell homogenates under denaturing conditions by metal-ion affinity chromatography in a single step and then was refolded. The hexahistidine tail could be removed when desired by digestion with Factor Xa. In a functional assay, the GM2-activator thus generated from Escherichia coli and renatured, with or without the hexahistidine tail, was as active as the native GM2-activator protein that was purified from human tissue. When added to the culture medium, the recombinant carbohydrate-free GM2-activator, carrying the hexahistidine tail, could be taken up efficiently and restored the degradation of ganglioside GM2 to normal rates in mutant fibroblasts with the AB variant of GM2-gangliosidosis, which is characterized by a genetic defect in the GM2-activator protein. The prokaryotic expression system is useful for producing milligram quantities of a pure and functionally active GM2-activator.

description: We propose and numerically implement a constitutive framework for granular media that allows the material to traverse through its many common phases during the flow process. When dense, the material is treated as a pressure sensitive elasto-viscoplastic solid obeying a yield criterion and a plastic flow rule given by the $μ(I)$ inertial rheology of granular materials. When the free volume exceeds a critical level, the material is deemed to separate and is treated as disconnected, stress-free media. A Material Point Method (MPM) procedure is written for the simulation of this model and many demonstrations are provided in different geometries. By using the MPM framework, extremely large strains and nonlinear deformations, which are common in granular flows, are representable. The method is verified numerically and its physical predictions are validated against known results.
Regulation of ligand binding to glycoprotein IIb-IIIa (integrin α IIb β 3 ) in isolated platelet membranes

description: The major platelet integrin, glycoprotein IIb-IIIa, binds soluble fibrinogen only after platelet activation. To investigate the mechanism by which platelets convert glycoprotein IIb-IIIa into a functional fibrinogen receptor, we characterized the opening and closing of fibrinogen-binding sites in isolated platelet membranes and compared the regulatory properties of membrane-bound glycoprotein IIb-IIIa with those of the detergent-solubilized receptor. Basal fibrinogen binding to the membranes possessed many of the properties of fibrinogen binding to activated platelets; however, less than 10% of glycoprotein IIb-IIIa in the membranes was capable of binding fibrinogen. Preincubating the membranes with either an activating glycoprotein IIb-IIIa antibody or alpha-chymotrypsin increased fibrinogen binding. In contrast, agents that require intracellular mediators, such as platelet agonists, guanine-nucleotide-binding-protein activators and purified protein kinase C, did not stimulate fibrinogen binding to the membranes, suggesting that cytosolic factor(s) may be required for activation of the receptor in platelets. Occupancy of glycoprotein IIb-IIIa in the membranes with RGD (Arg-Gly-Asp)-containing peptides reversibly exposed neoantigenic epitopes and fibrinogen-binding sites in the receptor. These conformational changes required membrane fixation to be maintained following peptide removal. Similar results were obtained with purified glycoprotein IIb-IIIa incorporated into phospholipid vesicles, indicating that the resting state of the receptor is favoured in these environments. In contrast, when the conformation of detergent-solubilized glycoprotein IIb-IIIa was altered by exposure to RGD-containing peptides, the receptor remained active even after incorporation into phospholipid vesicles. These results demonstrate that platelet membranes are a useful model in which to study the regulation of glycoprotein IIb-IIIa and suggest that the environment surrounding the receptor may have a profound influence on this process.

description: Native and recombinant neutrophil collagenase (MMP-8) was shown to cleave at the E(373)-A(374) 'aggrecanase'' site in the interglobular domain of aggrecan. The time course of digestion in vitro showed that MMP-8 cleaved initially at N-341-F-342, the predominant metalloproteinase site, before cleaving at the E(373)-A(374) site. A synthetic peptide, IPENFFG, inhibited cleavage at E(373)-A(374) but not N-341-F-342 in vitro, indicating that the E(373)-A(374) sequence was a less preferred site for MMP-8 cleavage than N-341-F-342. IPENFFG also inhibited release of A(374) RGSVI fragments from cartilage in explant culture, suggesting that a metalloproteinase cleaved at the aggrecanase site in situ. The possibility remains that 'aggrecanase' may be a metalloproteinase in cartilage.
Population divergence in nutrient-temperature interactions in Pieris rapae

description: The interaction between larval host plant quality and temperature can influence the short-term physiological rates and life-history traits of insect herbivores. These factors can vary locally, resulting in local adaptation in responses to diet and temperature, but the comparison of these interactions between populations is infrequently carried out. In this study, we examine how the macronutrient ratio of an artificial diet determines the larval growth, development, and survival of larval Pieris rapae (Lepidoptera: Pieridae) at different temperatures between two invasive North American populations from different climatic regions. We conducted a fully factorial experiment with three temperature treatments (18°C, 25°C, and 32°C) and three artificial diet treatments varying in terms of the ratio of protein to carbohydrate (low protein, balanced, and high protein). The effects of diet on life-history traits were greater at lower temperatures, but these differed between populations. Larvae from the subtropical population had reduced survival to pupation on the low-protein diet in the cold temperature treatment, whereas larval survival for the temperate population was equally high for all temperature and diet treatments. Overall, both populations performed more poorly (i.e., they showed slower rates of consumption, growth, and development, and had a smaller pupal mass) in the diet with the low protein ratio, but larvae from the temperate population were less sensitive to diet ratio changes at all temperatures. Our results confirm that the physiological and life-history consequences of imbalanced nutrition for insect herbivores may depend on developmental temperatures, and that different geographic populations of P. rapae within North America vary in their sensitivity to nutritional balance and temperature.

description: An engineer is interested in half-cell potential measurements because they give an idea about the possible state of corrosion of the steel reinforcement in concrete. Interpreting such measurements is trickier than just slapping one electrode here and another one there, and reading something meaningful from a voltmeter. After all, the concrete in the structure may have undergone carbonation, suffered chloride ion intrusion, and been mixed with anodic or cathodic corrosion inhibitors. The measurements are influenced by these and many other factors. Therefore, their correct interpretation is a matter of knowing what exactly the influences amount to.
description: Les ingénieurs s'intéressent aux relevés de potentiel par demi-pile parce que ceux-ci donnent une idée du degré de corrosion de l'armature d'acier contenue dans le béton. Pour interpréter ces relevés, il ne suffit pas de flanquer une électrode ici et une autre là, et de faire la lecture des résultats sur un voltmètre. Après tout, le béton dont est fait l'ouvrage peut avoir subi une carbonatation, sa concentration en ions chlorure peut avoir augmenté, ou on peut lui avoir ajouté un inhibiteur de corrosion anodique ou cathodique. Ces facteurs, et bien d'autres, influent sur les relevés. Pour interpréter correctement ceux-ci, il faut donc connaître l'effet exact de ces facteurs.

description: We prove that the defining equations of the Fermat curves of prime degree cannot be written as the determinant of symmetric matrices with entries in linear forms in three variables with rational coefficients. In the proof, we use a relation between symmetric matrices with entries in linear forms and non-effective theta characteristics on smooth plane curves. We also use some results of Gross-Rohrlich on the rational torsion points on the Jacobian varieties of the Fermat curves of prime degree.

The basis for conducting research is related to the phenomenon that occurs today, namely the suboptimal performance of lecturers in carrying out their duties and responsibilities, which has implications for the low achievement of the quality of the Tri Dharma of Higher Education. The general purpose of the research is to obtain a clear description, formulate and analyze the management of an integrated coaching model in improving lecturer performance in Private Universities (Universitas Komputer Indonesia dan Universitas Garut). The specific purpose of the research is to know, study, and analyze more deeply about planning, organizing, directing and supervising. What are the supporting and inhibiting factors, how to overcome obstacles and how the lecturers' work results after the implementation of the integrated coaching model. The theories used are; management theory from Nickels, McHug and McHugh, integrated coaching model theory from Jonathan Passmore, and performance theory from Bernardin and Russell. The research approach uses qualitative, with a descriptive method. Data collection techniques through interviews, observations, and documentation studies. Data analysis uses Miles & Huberman's interactive techniques. The results of the study showed; Planning is prepared in a visionary manner by prioritizing logic, clarity and reality that occurs. The organization is arranged neatly, well and correctly. The briefing is arranged in a coordinated, communicative and continuous manner. Supervision is prepared in a continuous, useful, comprehensive and accurate manner. There are supporting and inhibiting factors from the aspect; Human resources, budget, infrastructure and commitment in realizing the program.
