Global use of urea nitrogen (N) fertilizer is increasing, but N losses are still very high (40–70%). Zeolites have the capability of holding NH4+, thus reducing N losses when applied as a soil amendment. However, application of a large quantity of zeolite is costly and inconvenient. In this study, zeolitic fertilizers were evaluated to select the best formulation with reduced leaching of NH4-N and NO3-N and NH3 volatilization in agricultural soils (Alfisol and Spodosol). The treatments included the following: T0 = control, T1 = urea fertilizer, T2 = zeo-urea (1:1), T3 = zeo-urea (2:1), T4 = zeo-urea (3:1), T5 = zeo-urea (1:2), and T6 = zeo-urea (1:3). Leaching was performed at 4, 8, 12, 19, 25, 32, 39 and 45 days after the soils were treated with the designated fertilizers, including control, and packed into columns. Leachate samples were collected after each leaching event and analyzed for the concentrations of NH4-N and NO3-N and the quantity of leachate. Ammonia volatilization was recorded at days 1, 5, 9, 13 and 20 of soil treatments. Results indicate that zeolitic fertilizer formulations effectively reduced N losses. NH4-N loss was reduced by 13% and 28% by zeo-urea (1:1) in Alfisol and Spodosol soils, respectively, whereas zeo-urea (2:1) and zeo-urea (3:1) effectively decreased NO3-N leaching in Alfisol. Volatilization loss of NH3 was reduced by 47% in Spodosol and 32% in Alfisol soil with zeo-urea (1:1) as compared with that of urea fertilizer. The results suggest that zeo-urea (1:1) is an effective fertilizer formulation for reducing N losses, especially in Alfisol, as compared with conventional urea fertilizer.

In this work, a low-cost, high-yield hydrothermal treatment was used to produce nanozeolite (Zeo), nanoserpentine (Serp), and Zeo/Serp nanocomposites with weight ratios of 1:1 and 2:1. At 250 °C for six hours, the hydrothermal treatment was conducted. Various methods are used to explore the morphologies, structures, compositions, and optical characteristics of the generated nanostructures. The morphological study revealed structures made of nanofibers, nanorods, and hybrid nanofibril/nanorods. The structural study showed clinoptilolite monoclinic zeolite and antigorite monoclinic serpentine with traces of talcum mineral and carbonates. As a novel photoelectrochemical catalyst, the performance of the Zeo/Serp (2:1) composite was evaluated for solar hydrogen generation from water splitting relative to its constituents. At −1 V, the Zeo/Serp (2:1) composite produced a maximum current density of 8.44 mA/g versus 7.01, 6.74, and 6.6 mA/g for hydrothermally treated Zeo/Serp (1:1), Zeo, and Serp, respectively. The Zeo/Serp (2:1) photocatalysts had a solar-to-hydrogen conversion efficiency (STH) of 6.5% and an estimated hydrogen output rate of 14.43 mmole/h.g. Consequently, the current research paved the way for low-cost photoelectrochemical catalytic material for efficient solar hydrogen production by water splitting.

Los antioxidantes se emplean rutinariamente como aditivos alimenticios en la producción de pollos de engorda. Entre ellos destaca el ácido alfa lipoico (AAL), ya que su adición en la dieta (40 mg kg-1) mejora la ganancia de peso y la conversión alimenticia. Dado el alto precio del AAL, el objetivo de este trabajo fue estudiar el uso al combinarlo con nanoestructuras, las cuales pudieran conferirle ventajas de asimilación y por consiguiente, abatir costos de producción por concepto de alimentación. Para ello el AAL se inmovilizó con zeolita nanoestructurada tipo mordenita (Zeo) y se compararon sus efectos con las del AAL libre. La capacidad antioxidante del complejo (Zeo-AAL) es menor que la del compuesto libre, aun así, Zeo-AAL muestra una capacidad antioxidante importante. El AAL se libera mejor del complejo Zeo-AAL si éste se coloca en un ambiente simulando las condiciones del tubo digestivo, en comparación con su liberación en un ambiente sanguíneo. En la dieta de los pollos se evaluó el efecto del AAL libre (40 mg kg-1) comparativamente con los del Zeo-AAL (0, 10 y 40 mg kg-1), sobre las variables productivas y el rendimiento de la canal. El AAL nanoestructurado con Zeo no representó ninguna ventaja sobre el AAL libre (P>0.10), por lo que deberán de seguirse buscando estrategias con otras nanopartículas o compuestos nanoestructurados que permitan en un futuro bajar el costo en el uso del AAL sin disminuir sus beneficios probados.

The main strategies against Triatoma infestans (primary vector responsible for the Chagas disease transmission) are the elimination or reduction of its abundance in homes through the application of insecticides or repellents with residual power, and environmental management through the improvement of housing. The use of plant-derived compounds as a source of therapeutic agents (i.e., essential oils from aromatic plants and their components) is a valuable alternative to conventional insecticides and repellents. Essential oil-based insect repellents are environmentally friendly and provide reliable personal protection against the bites of mosquitoes and other blood-sucking insects. This study investigates, for the first time to our knowledge, the potential repellent activity of Zuccagnia punctata essential oil (ZEO) and poly(ε-caprolactone) matrices loaded with ZEO (ZEOP) prepared by solvent casting. The analysis of its essential oil from aerial parts by GC–FID and GC-MS, MS allowed the identification of 25 constituents representing 99.5% of the composition. The main components of the oil were identified as (−)-5,6-dehydrocamphor (62.4%), alpha-pinene (9.1%), thuja-2, 4 (10)-diene (4.6%) and dihydroeugenol (4.5%). ZEOP matrices were homogeneous and opaque, with thickness of 800 ± 140 µm and encapsulation efficiency values above 98%. ZEO and ZEOP at the lowest dose (0.5% wt./wt., 96 h) showed a repellency of 33 and 73% respectively, while at the highest dose (1% wt./wt., 96 h) exhibited a repellent activity of 40 and 66 %, respectively. On the other hand, until 72 h, ZEO showed a strong repellent activity against T. infestans (88% repellency average; Class V) to both concentrations, compared with positive control N-N diethyl-3-methylbenzamide (DEET). The essential oils from the Andean flora have shown an excellent repellent activity, highlighting the repellent activity of Zuccagnia punctata. The effectiveness of ZEO was extended by its incorporation in polymeric systems and could have a potential home or peridomiciliary use, which might help prevent, or at least reduce, Chagas’ disease transmission.

In our research, a composite film of whey protein isolate (WPI)/chitosan incorporated with TiO2 nanoparticles (NPs) and essential oil of Zataria multiflora (ZEO) was developed. The resulting composite films were evaluated by FTIR, SEM, and XRD, and also the physicochemical characteristics including color, mechanical properties, swelling ratio, and water vapor permeability (WVP) were studied. SEM graphs exhibited that the samples had a uniform and homogeneous structure where TiO2 NPs and ZEO were well dispersed. FTIR and XRD findings also show that the hydrogen bonds and hydrophobic interactions are the main interactions between the composite WPI/chitosan and TiO2. The crystalline nature of the composite samples increased with the increase of NP content. Nevertheless, ZEO had an insignificant effect on the functional groups and the crystallinity of composite samples. The film visual characterization revealed that, by adding and increasing the TiO2 and TiO2-ZEO, sample lightness and opacity significantly increased. Additions of TiO2 remarkably (p<0.05) improved the water vapor and mechanical properties of composite samples, although the loading of ZEO, regardless of TiO2 incorporation, led to a considerable decrement of these properties. Furthermore, composite films containing ZEO combined with 2% of TiO2 compared with 1% of NPs blended with ZEO had strong antimicrobial properties against Staphylococcus aureus, Escherichia coli, and Listeria monocytogenes. Generally, the findings proposed that the addition of TiO2 reinforces the properties of composite films with a synergistic effect of ZEO loading on the antibacterial ability, by which the resulting biodegradable composite samples can be used as a food active packaging material.

T he current study reports the use of zeolite prepared from a kaolin composite via physical mixing with different ratios from fiber of palm tree (Zeo-FPT) as a sustainable solid sorbent for the removal of methylene blue (MB) dye from aqueous solutions. The prepared biosorbent was fully characterized using XRD, TGA, SEM, and FTIR. The impacts of various analytical parameters, for example, contact time, dosage, MB dye concentration, and the pH of the solution, on the dye adsorption process were determined. After a contact time of 40 min, the capacity to remove MB dye was 0.438 mg g−1 at a Zeo-FPT composition ratio of 1F:1Z. At pH 8, Zeo-FPT (1F:1Z) had a removal efficiency of 87% at a sorbent dosage of 0.5 g for a concentration of MB dye in an aqueous phase of 10 mg L−1. The experimental data were also analyzed using the kinetic and adsorption isotherm models. The retention process fitted well with the pseudo-second-order model (R2 0.998), where the Qe,calc of 0.353 mg g−1 was in acceptable agreement with the Qe,exp of 0.438 mg g−1. The data also fitted well with the Freundlich isotherm model, as indicated by the correlation coefficient value (R2 0.969). The Zeo-FPT attained a high percentage (99%) in the removal of MB dye from environmental water samples (tap water, bottled water, and well water). Thus, it can be concluded that the proposed zeolite composite with fiber of palm tree (Zeo-FPT) is a suitable, environmentally friendly, and low-cost adsorbent for removing dyes from wastewater.

One of the most important issues for modern agriculture is how to decrease fertilization rates and enhance the sustainability of crops, without decreasing yields. Two inorganic (zeolite—zeo; vermiculite—ver) amendments and their mixtures with an organic soil amendment (goat manure) (i.e., zeo + ver, manure + ver, manure + zeo) were tested, and compared to the application of a controlled release fertilizer (CRF), in order to investigate if they were able to satisfy the nutritional needs of Solanum lycopersicon L. plants. For this purpose, a 112-day pot experiment was performed. After zeo and manure application, exchangeable K was increased from 16.5 times to 37.5 times. At the end of the experiment, total plant biomass was significantly higher in the CRF treatment, compared to the ver treatments (ver, ver + manure). Leaf K concentration was significantly higher in the zeo treatment (5.93% dw), compared to those determined in the CRF, ver, and ver + manure. In contrast, significantly higher foliar N was found in the CRF (4.83% dw) and zeo + ver (4.24% dw) treatments, compared to manure + ver. Finally, photosystem II (PSII) activity was significantly higher in ver, and this was ascribed to the optimum foliar Mn found in this treatment (138 mg kg−1 dw). It is expected that these data will provide a thorough insight towards decreasing chemical fertilization inputs and enhancing the sustainability of Solanum lycopersicon L. crop.

Background: Biodegradable films are appropriate alternatives to synthetic polymers due to their potential to enhance food safety and their function as a carrier for wide a range of food additives especially natural antioxidants. Objective: The aim of this study was to compare the potential antioxidant activities of sodium alginate films containing resveratrol (RES) alone and in combination with Zataria multiflora essential oil (ZEO) using an in vitro model. Methods: At first, the major chemical compositions of ZEO were evaluated by GC/MS. Then, the amount of phenolic compounds of sodium alginate films were evaluated by total phenolic contents assay and antioxidant activities of films were evaluated by 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays. Finally, the concentrations of ZEO and RES which showed better antioxidant activities in sodium alginate films were incorporated to films in combination forms to evaluate their synergistic effects. Results: According to gas chromatography-mass spectrometry (GC/MS) analysis, 35 compounds of ZEO were identified and Thymol (37.94%), p-Cymene (9.50%) and 3-Carene (4.98%) were the most important compounds of essential oil, respectively. The results of the radical scavenging evaluations, showed better antioxidant activities of the films containing RES than the films containing ZEO and Butylated hydroxytoluene (BHT). Also, the combined uses of ZEO and RES into alginate films had the synergistic effects (P<0.05). Conclusion: Therefore, it can be concluded that alginate films incorporated with the combination of ZEO and RES is the appropriate option to postpone the oxidative reactions and can be used as natural antioxidant in the food packaging industry.

The reclamation of domestic wastewater for irrigation is one alternative approach to solve the water scarcity crisis, but it is essential to control the microbiological quality of wastewater used for irrigation. The removal of thermotolerant coliforms, also known as faecal coliforms (FC), from treated domestic wastewater by intermittent media infiltration (IMI) in column was studied. The columns were filled with natural filter media (soil, soil/charcoal and zinc-modified zeolite, Zeo-Zn), and wastewater, IMI-treated wastewater and disinfected wastewater were compared. The numbers of residual FC on Swiss chard (Beta vulgaris) and in agricultural soil were determined over a 4-month period. The column using Zeo-Zn had a higher FC removal efficiency (2.98 log) than columns with other filter media and disinfection (1.87–2.57 log) due to the bactericidal properties of Zn2+. The treatment of wastewater using Zeo-Zn and disinfection both decreased the accumulation of FC on plants and in soil to approximately 1–20 MPN/g dry matter. IMI-treated wastewater using the column with Zeo-Zn was suitable for unrestricted agricultural use, complied with Mexican regulations (as did disinfected wastewater) and had a low risk of FC contamination of plants and soil.

Hypocalcaemia is an important disorder associated with an increased risk of metabolic diseases, and many studies have been going on for decades. This study investigated the effects of anionic and zeolite with an oral Ca bolus in the prepartum phase on milk yields and compositions, and plasma Ca concentrations, blood metabolites and the prevalence of some reproductive disorders in dairy cows after parturition. Ninety pregnant non-lactating Holstein-Friesian cows were randomly assigned to three isoenergetic diets and their counterparts using an oral Ca bolus: (1) Control (CON): low Ca (0.44%); (2) Anionic (ANI): high Ca (1.00%); (3) Zeolite (ZEO): low Ca (0.44%). The feed and energy intakes of the CON and ZEO groups were higher than the ANI group. The raw milk yield, Pr%, and feed efficiency did not differ between the groups, while the corrected milk yield, fat% and total corrected milk yield at 305 days differed between groups. Total plasma and the ionized Ca concentration of the ANI and ZEO groups, at calving time and in 6, 12, 24 and 48 h after that, were higher than in the CON group. The frequencies of hypocalcaemia and reproductive disorders in the ANI and ZEO groups were lower than in the CON. The blood metabolite levels in the CON group were higher than in other groups. In conclusion, the ANI and ZEO diets and their counterparts supplemented with an oral Ca bolus improved the milk production traits, plasma calcium and metabolites concentration and also effectively prevented reproductive disorders.

Les zéolites sont des matériaux poreux cristallins uniformesformés d'unités TO4 partageant un sommet (T = Si, Al, Ge, etc.). Ils sont préparés sous des conditions hydrothermales, en mélangeant un agent directeur de structure (SDA) approprié avec un gel contenant des composants inorganiques tels que la silice, l'alumine ou le germanium. À un pH et une température spécifiques, le SDA induit la nucléation et la croissance cristalline pour obtenir des zéolites de taille, de forme et de dimension spécifiques. Les zéolites à pores de taille extra-large avec une ouverture de pore supérieure à 0,75 nm suscitent un intérêt croissant de la part des chercheurs en raison de leur activité prometteuse dans le traitement de molécules plus volumineuses, de l'amélioration de la vitesse de diffusion, de la prolongation de la durée de vie du catalyseur et du changement de la sélectivité du produit.Notre objectif est de préparer des SDA avec des substitutions alkyliques différentes en suivant une approche d'expansion de taille, en synthétisant des sels d'ammonium contenant une ou deux entités alcyne. De plus, des sels d'ammonium à base d'imidazole, d'hexaméthylénétanétramine et de composés de 4-phénylpyrridine - ainsi que des voies de synthèse pour la préparation de sels d'ammonium à base de [2.2] paracyclophane en utilisant la réaction de King ont été explorées. En outre, des sels organiques à base de phosphore ont été synthétisés. La préparation, la purification et les premiers résultats de leur utilisation comme SDA dans la synthèse des zéolites seront présentés dans cette thèse
Zeolites are uniformly crystalline porous materials formed of a vertex sharing TO4 units (T= Si, Al, Ge, etc.). They are prepared under hydrothermal conditions, by mixing a suitable structure directing agent (SDA) with a gel containing inorganic components such as silica, alumina or germanium. At specific pH and temperature, the SDA induces nucleation, seed formation and crystal growth to obtain zeolites with specific size, shape and dimension. Extra-large pore size zeolites with pore aperture larger than 0.75 nm aroused increasing interest from researchers due to their promising activity in processing bulkier molecules, improving diffusion rate, prolonging the catalyst lifetime and changing product selectivity. Our goal is to prepare SDA’s having different alkyl substituents following size expansion approach, by synthesizing ammonium salts containing either one or two alkyne moieties. Furthermore, ammonium salts based on imidazole, hexamethyl-enetetramine and 4-phenylpyridine compounds – as well as synthetic paths for the preparation of [2.2] paracyclophane based ammonium salts using King’s reaction were explored. Additionally, organic salts based on phosphorous were synthesized. Preparation, purification and preliminary results of their use as SDAs in zeolite synthesis will be shown in this thesis

Coal in the finer particle size ranges (below 1 mm) has always suffered from poor cleaning efficiencies. This problem has been exacerbated in recent years with the increased amount of high ash fines due to continuous mining machines and the mining of dirtier coal seams. In the present work, it is proposed to improve overall plant efficiencies by processing coarser coal in column flotation than is now commonly treated by that method. Column flotation for coarse coal is supported by actual lab and plant test data that result in a full-scale column plant installation. The fundamentals of coarse particle detachment from bubbles are reviewed and a new simplified model is developed which better handles cubical and rectangular coal particles. Much of the lower efficiency of fine coal cleaning is due to poor size separation of the fine-sized raw coal which results in misplaced high ash fines reporting to the coarser size streams. By sending coarser material to column flotation, the finest size separation that takes place in a plant can be as coarse as 0.5 mm or greater. The proper use of wash water in a flotation column then becomes the best mechanism for desliming of the high ash clays. This work quantifies the benefits of removing the high ash fines from the plant product and increasing overall plant yield by increasing the amount of near-gravity coarse material. The resulting yield gain is greater than that obtained from only the increased fine coal recovery. Methods of column operation for improved coarse coal recovery are also evaluated.

We present a new rearrangement of short-range interactions in the S-1(0) nucleon-nucleon channel within chiral effective field theory. This is intended to address the slow convergence of Weinberg's scheme, which we attribute to its failure to reproduce the amplitude zero (scattering momentum similar or equal to 340 MeV) at leading order. After the power counting scheme is modified to accommodate the zero at leading order, it includes subleading corrections perturbatively in a way that is consistent with renormalization-group invariance. Systematic improvement is shown at next-to-leading order, and we obtain results that fit empirical phase shifts remarkably well all the way up to the pion-production threshold. An approach in which pions have been integrated out is included, which allows us to derive analytic results that also fit phenomenology surprisingly well.

Lattice simulations of the 3+1 dimensional Nambu-Jona-Lasinio model are undertaken that provide non-perturbative evidence for the existence of a BCS superfluid phase in the low temperature, high density regime. Standard analytic methods are used to fit the model's free parameters to low energy vacuum phenomenology. The model is simulated numerically for a range of baryon chemical potential mu, with the introduction of a diquark source j to allow for the observation of spontaneous U(1) global symmetry breaking in a finite volume system. For mu ≥ 0.6 inverse lattice spacings and in the limit that j → 0, a non-zero diquark condensate, a vanishing diquark susceptibility ratio and an energy gap Delta ≠ 0 about the Fermi surface in the fermion dispersion relation are all consistent with the ground-state being that of a U(l)-broken BCS superfluid. The ratio between the gap at mu = 0.8 and the vacuum fermion mass is found to be 0.15(2). This is interpreted as tentative non-perturbative evidence for the existence of a colour superconducting phase in cold, dense QCD. The effects of simulating on a finite volume, and any conditions this places on the above conclusions, are investigated. Finally, the results of some initial studies at non-zero isospin chemical potential and the prospect of simulations at non-zero temperature are discussed.

In una formulazione rigorosa della teoria quantistica, la definizione della varietà Riemanniana spaziale su cui il sistema è vincolato gioca un ruolo fondamentale. La presenza di un bordo sottolinea l'aspetto quantistico del sistema: l'imposizione di condizioni al contorno determina la discretizzazione degli autovalori del Laplaciano, come accade con condizioni note quali quelle periodiche, di Neumann o di Dirichlet. Tuttavia, non sono le uniche possibili. Qualsiasi condizione al bordo che garantisca l'autoaggiunzione dell' operatore Hamiltoniano è ammissibile. Tutte le possibili boundary conditions possono essere catalogate a partire dalla richiesta di conservazione del flusso al bordo della varietà. Alcune possibili condizioni al contorno, permettono l'esistenza di stati legati al bordo, cioè autostati dell' Hamiltoniana con autovalori negativi, detti edge states. Lo scopo di questa tesi è quello di investigare gli effetti di bordo in sistemi unidimensionali implementati su un reticolo discreto, nella prospettiva di capire come simulare proprietà di edge in un reticolo ottico. Il primo caso considerato è un sistema di elettroni liberi. La presenza di edge states è completamente determinata dai parametri di bordo del Laplaciano discreto. Al massimo due edge states emergono, e possono essere legati all' estremità destra o sinistra della catena a seconda delle condizioni al contorno. Anche il modo in cui decadono dal bordo al bulk e completamente determinato dalla scelta delle condizioni. Ammettendo un' interazione quadratica tra siti primi vicini, un secondo tipo di stati emerge in relazione sia alle condizioni al contorno che ai parametri del bulk. Questi stati sono chiamati zero modes, in quanto esiste la possibilità che siano degeneri con lo stato fondamentale. Per implementare le più generali condizioni al contorno, specialmente nel caso interagente, è necessario utilizzare un metodo generale per la diagonalizzazione, che estende la tecnica di Lieb-Shultz-Mattis per Hamiltoniane quadratiche a matrici complesse.

AbstractThis chapter focuses on innovation in mechanisms to finance the transformation of food systems to end hunger by 2030 and achieve SDG2. The key questions analyzed are: given the estimated costs involved in the transformation of food systems to achieve zero hunger, (1) What are the financing options available? (2) What is their quantitative availability? and (3) How to mobilize/reallocate the potential sources of finance? The concepts proposed here include international development finance, public budgets, banking, and capital markets at the global and national levels. A robust pipeline of investable opportunities should be established with an adequate profile and clear, measurable, and monitorable impact objectives, aligned with achieving SDG2 and ending hunger. Guarantee for “zero hunger” bonds is proposed to finance related public programs, and, in support of that, it is suggested that 2% of the new allocation of SDRs of 650 billion dollars be assigned to a fund, which could be set up within the IMF, to guarantee the interest rate payments of zero hunger bonds issued by developing countries as part of a Zero Hunger Alliance.

AbstractVision Zero is a term mainly connected with road traffic safety and has its roots in the Swedish road safety strategy. It was formally adopted by the Swedish parliament in 1997, and due to the initial success of lowering the number of deaths in traffic crashes significantly, it has become a role model for road safety strategies in countries and cities all over the world. In Sweden, Vision Zero for road safety has also inspired the introduction of Vision Zero policies in other sectors, and this chapter focuses on Vision Zero from a multi-sectoral perspective. The purpose of this chapter is twofold: to present five different cases of Vision Zero policies and to discuss what constitutes a Vision Zero policy based on these five cases. The five cases are found in road traffic safety, fire safety, patient safety, suicide, and workplace safety. Every case has its unique preconditions in terms of laws, actors, scope, etc., but they are also similar in relation to injury prevention and the ambition to decrease the number of deaths and serious injuries. The five Vision Zero policies are summarized by presenting the problem and problem framing, the goal, measures, and solutions as well as leading actors and governing structures. We find that the problem itself is quite self-explanatory in each case but that the problem framing and attribution of responsibility differ. All cases have on paper been inspired by the road safety strategies, but the systems approach, so intimately connected with Vision Zero, is more or less absent in the cases of fire safety and suicide. Furthermore, in the field of fire safety, responsibility is placed on the individual and on the business sector rather than based on a shared responsibility and ultimately on the system designers. In all five cases, there are a set of measures in place, but there are differences in implementation due to temporal factors and also what kind of governing and steering structures are in place. There is also a difference in internal support where the Vision Zero for suicide stands out as having less support among agencies working with the issue. Finally, the monitoring systems differ from case to case. The Vision Zero for road traffic safety stands out as having a monitoring and evaluating system based on specific safety targets ultimately aiming toward zero (management by objectives). Based on the empirical findings, we argue that besides having a clear problem and problem framing, a toolbox of measures, a monitoring system, and a governing structure, a policy based on a visionary approach with an ambition to reach zero needs additional perspectives or criteria in order to be successful: (1) a scientific approach to problem framing and solutions, (2) a comprehensive approach, (3) a long-term commitment, and (4) a system and structure based on governance. These criteria do not necessarily have to be in place in order to adopt Vision Zero, but they are a prerequisite for building a system based on Vision Zero.

AbstractThis chapter describes the adoption of Vision Zero in Norway and some of the impacts on transport safety policy that can be traced to it. These impacts concern the following: the demand for improved knowledge about the effects of road safety measures, the creation of a new forum for developing road safety policy, the adoption of quantified road safety targets and a system for management by objectives based on road safety indicators, the identification of roads suitable for conversion to motorways or to 2+1 roads based on the Swedish model, the revision of speed limit policy and the revision of standards for the design and use of guardrails. It is argued that the adoption of Vision Zero has had a major impact on road safety policy in Norway and may have contributed to speeding up the decline in the number of traffic fatalities and serious injuries after the year 2000.

The ability to investigate sleep is of scientific and clinical interest. Polysomnography (PSG) has long been considered the gold standard assessment for sleep physiology; however, its cost and inconvenience have spurred the development of consumer devices capable of evaluating sleep outside the laboratory. The development of dedicated consumer sleep monitoring devices, e.g., the Zeo Personal Sleep Manager, smart bands, e.g., the Microsoft Band 2 (MB2), and activity trackers, e.g., the Fitbit Charge 2 (FC2), with the ability to automatically distinguish between sleep and wakefulness has important implications for sleep research and medicine.1–3

Developers, building owners, and design teams often point to initial capital costs as the primary obstacle hindering the uptake of net-zero buildings. In-depth research and an understanding of whether net-zero buildings cost more to design and construct are still scattered and non-systemic. Accordingly, this study provides the first comprehensive investigation into actual net-zero building construction costs in the United States, based on qualitative and quantitative research. The aims of this research are to: (1) provide a comprehensive survey of the existing body of literature to aggregate the findings and identify the consensus and pattern, (2) compare the results and analyze the evidence with a focus on quantitative studies, and (3) conduct a quantitative comparative analysis of twelve built zero energy buildings (ZEB) in order to under¬stand whether there is enough evidence of cost differences between ZEB, conventional building (CB) and green building (GB). Statistical tests were performed, with the results show¬ing no significant differences between actual ZEB costs and modeled CB costs. Further details investigated the cost difference between actual ZEB and modeled GB. The findings of this research provide initial detailed insights into net-zero building costs in the United States, which may benefit the promotion of ZEB practices.

Due to the high heating demand, energy savings in residential buildings in cold climates has played an important role in reducing carbon emissions. The goal of this study is to investigate the difference of current multifamily buildings’ energy retrofit practices in the United States and Finland, with aim to achieve net zero energy or nearly net zero energy. Altogether, data of 57 net zero (ZEB) and nearly net zero energy (nZEB) multifamily buildings from both countries were collected and analyzed. The preliminary results indicate three differences: (1) for existing multifamily building stock, the United States has higher average energy use 266 kWh/m2, compared to that of Finland at 220-250 kWh/m2; (2) Finland has much more strict energy code requirements that contribute to the lower energy use in the similar climate condition; (3) in the built nZEB and ZEB projects, the average energy in United States is 1.7 times higher than in Finland.

California faces unprecedented uncertainty about how much revenue the state will raise from a package of taxes on motor fuels and annual registration fees on light-duty vehicles that was established in 2017 by Senate Bill 1 (SB 1). The SB 1 taxes are by far the largest source of revenue that the State of California generates to support maintenance, operations, and improvements for state highways, and the funds also contribute substantially to local transportation and public transit budgets. To help policymakers navigate the uncertainty about future SB 1 transportation revenue, this study used spreadsheet models to project revenue from the SB 1 taxes through 2040 under a set of eight scenarios that consider a wide range of possible futures. The scenarios consider changes to revenue that could arise from implementation of California’s zero-emission vehicle (ZEV) regulations, as well as potential changes in driving costs, population size, vehicle ownership rates, and trucking industry operations. Key findings include: • It is impossible to project future revenues with any confidence for more than a few years into the future. By 2040, annual revenue ranges from a low of $4.81 billion to a high of $12.15 billion. • The state may lose substantial revenue if the SB 1 taxes and fees are not changed and/or replaced within the coming few years. In 2027, just three years out, projected annual revenue for some scenarios drops by more than a billion dollars below 2024 revenue. • A fast ICE to ZEV transition would significantly reduce annual revenue—but so could changes in VMT. • Fuel taxes currently provide most SB 1 revenue, but by 2040 California may rely on vehicle registration fees to provide most of the revenue.

We study the use of a zero mean first difference model to forecast the level of a scalar time series that is stationary in levels. Let bias be the average value of a series of forecast errors. Then the bias of forecasts from a misspecified ARMA model for the first difference of the series will tend to be smaller in magnitude than the bias of forecasts from a correctly specified model for the level of the series. Formally, let P be the number of forecasts. Then the bias from the first difference model has expectation zero and a variance that is O(1/P²), while the variance of the bias from the levels model is generally O(1/P). With a driftless random walk as our first difference model, we confirm this theoretical result with simulations and empirical work: random walk bias is generally one-tenth to one-half that of an appropriately specified model fit to levels.

Esta publicación analiza la situación de las empresas en Latinoamérica y el Caribe (LAC) en relación a los compromisos ambientales vinculados a la carbono neutralidad y algunos avances realizados en la implementación de medidas para alcanzar los compromisos climáticos. El Acuerdo de París establece medidas para la reducción de las emisiones de gases de efecto invernadero (alcance 1, 2 y 3) que incluye compromisos climáticos de carbono neutralidad y net-zero. Esta publicación describe las principales organizaciones y estructuras que soportan la agenda global de compromisos alineados con la ciencia, considerando las campañas, coaliciones y organizaciones metodológicas y de estándares. También, se incorporan algunos casos de éxito de compromisos net-zero en Latinoamérica y el Caribe y se identifican desafíos y recomendaciones para las empresas en LAC en términos de compromisos climáticos.

2022an eta 2023an elektrizitate merkatuaren diseinuaren inguruko eztabaida sakona izan zen Europar Batasunean, zalantzan jarri baitzen diseinu hori egokiena ote zen energia merkatuetan estres egoereiaurre egiteko, kontsumitzaileak babesteko eta energia berriztagarritan beharrezkoak diren inbertsioak sustatzeko. Eztabaidan bi ikuspegi izan ziren aurrez aurre: (1) esku hartzearen aldeko jarrera (besteakbeste, Espainiako Gobernuak babesten zuena), merkatuko prezioak eta enpresa sortzaileen diru sarrerak kontrolatzea azpimarratzen zituena, gaur egun indarrean dagoen diseinua, neurri handi batean,baliogabetuz, eta (2) erreformaren aldeko jarrera, gaur egungo diseinua osatzea helburu zuena,merkatuaren erresilientzia eta kontsumitzaileen babesa hobetzeko elementuak txertatuta, EuropakoBatzordeak 2023ko martxoan egin zuen proposamenean jasotzen den bezala. Txosten honek eztabaida hori du aztergai eta Europako Parlamentuak eta Europako Kontseiluak 2023ko abenduan lortu zuten azken akordioaren xehetasunak azaltzen ditu. Akordio horrek Europako Batzordeak egindako erreforma proposamenaren funtsezko elementuei eutsi zien eta aldaketak proposatu zituen energiaren barne merkatuaren garapena osatzeko, kontsumitzaile kalteberenak babesteko, energiaren kostuaren egonkortasuna eta aurreikusgarritasuna handitzeko, eta energia berriztagarrietan eta malgutasunean inbertsioak egiteko pizgarriak sortzeko.
