Abstract:
Abstract Stably stratified shear-driven turbulence is analyzed using the gradient Richardson number, Ri, as the stability parameter. The method overcomes the statistical problems associated with the widely used Monin–Obukhov stability parameter. The results of the Ri-based scaling confirm the presence of three regimes: the weakly and the very stable regimes and the transition in between them. In the weakly stable regime, fluxes scale in proportion with variance, while in the very stable regime, stress and scalar fluxes behave differently. At large Ri, the velocity field becomes highly anisotropic and the turbulent potential energy becomes approximately equal to half of the turbulent kinetic energy. It appears that even in the strongly stable regime, beyond what is known as the critical gradient Richardson number, turbulent motions are present.

Abstract:
Tool wear and workpiece overcut have been studied in electrical discharge machining process with rotational external magnetic field and rotational electrode. Experiments have been divided to three main regimes, namely, low-energy regime, middle-energy regime, and high-energy regime. The influence of process parameters were investigated on electrode wear rate and overcut. Results indicate that applying a magnetic field around the machining gap increases the electrode wear rate and overcut. Also, rotation of the tool has negative effect on overcut.

Abstract:
We study the absorption and scattering of massless scalar waves propagating in spherically symmetric spacetimes with dynamical cosmological constant both in low-energy and high-energy zones. In the former low-energy regime, we solve analytically the Regge–Wheeler wave equation and obtain an analytic absorption probability expression which varies with [Formula: see text], where M is the central mass and Λ is cosmological constant. The low-energy absorption probability, which is in the range of [0, 0.986701], increases monotonically with increase in Λ. In the latter high-energy regime, the scalar particles adopt their geometric optics limit value. The trajectory equation with effective potential emerges and the analytic high-energy greybody factor, which is relevant with the area of classically accessible regime, also increases monotonically with increase in Λ, as long Λ is less than or of the order of 104. In this high-energy case, the null cosmological constant result reduces to the Schwarzschild value [Formula: see text].

Abstract:
AbstractWe consider rotating Rayleigh–Bénard convection of a fluid with a Prandtl number of $\mathit{Pr}=0.8$ in a cylindrical cell with an aspect ratio ${\it\Gamma}=1/2$. Direct numerical simulations (DNS) were performed for the Rayleigh number range $10^{5}\leqslant \mathit{Ra}\leqslant 10^{9}$ and the inverse Rossby number range $0\leqslant 1/\mathit{Ro}\leqslant 20$. We propose a method to capture regime transitions based on the decomposition of the velocity field into toroidal and poloidal parts. We identify four different regimes. First, a buoyancy-dominated regime occurring while the toroidal energy $e_{tor}$ is not affected by rotation and remains equal to that in the non-rotating case, $e_{tor}^{0}$. Second, a rotation-influenced regime, starting at rotation rates where $e_{tor}>e_{tor}^{0}$ and ending at a critical inverse Rossby number $1/\mathit{Ro}_{cr}$ that is determined by the balance of the toroidal and poloidal energy, $e_{tor}=e_{pol}$. Third, a rotation-dominated regime, where the toroidal energy $e_{tor}$ is larger than both $e_{pol}$ and $e_{tor}^{0}$. Fourth, a geostrophic regime for high rotation rates where the toroidal energy drops below the value for non-rotating convection.

Abstract:
Some new developments obtained in the last few years concerning the propagation of high energy cosmic rays are discussed. In particular, it is shown how the inclusion of drift effects in the transport diffusion equations leads naturally to an explanation for the knee, for the second knee and for the observed behavior of the composition and anisotropies between the knee and the ankle. It is shown that the trend towards a heavier composition above the knee has significant impact on the predicted neutrino fluxes above 1014 eV. The effects of magnetic lensing on the cosmic rays with energies above the ankle are also discussed, analyzing the main features of the different regimes that appear between the diffusive behavior that takes place at lower energies and the regime of small deflections present at the highest ones.

Abstract:
The aim of this Thesis is to study the development of pulsar wind nebulae in the TeV regime and in doing so uncover more sources which have as yet not been observed at these wavelengths. It is found that the extent of pulsar wind nebula in the TeV gamma-ray increases with its age while no developmental relationship is seen concerning the luminosity or spectral index of the nebulae when observed in the TeV gamma-ray regime due to uncertainties in the measurements available. TeV gamma-ray upper limits are calculated for several nebulae observed in the X-ray regime allowing the strength of their magnetic fields to be constrained but only one new source, which was previously confused with its companion, was discovered, the Eel Nebula. Predictions of the fluxes of many of the sources for which upper limits are derived in this work have been calculated from observations of their emission in X-rays and some of these sources should be uncovered with the next generation CTA instrument.

The productive section of meat should implement technologies that produce younger animals, with racial characteristics that promote quality meat. The manipulation of the diet and use of industrial crossing are technologies of easy access to the producer. Sixty cattle castrated with 18 moths of age, being 20 Nellore (NE), F1 Simmental x Nellore, F1 Angus x Nellore with average body weight of 265.6±6.4, 325.3±4.7 kg and 324.6±6.0 kg, respectively. The experiment was in completely randomized experimental design, in factorial 3 x 3, being 3 genetics groups (Nellore, F1 Simmental x Nellore, F1 Angus x Nellore) and 3 alimentary regimes (feeding to the maintenance level and ad libitum with 1% and 2% of the corporal weight (CW) at concentrated in natural matter of the diet), composing, therefore, 9 treatments, with 6 repetitions in each genetic group in the feeding levels ad libitum (1% and 2%) and four repetitions for the restricted feeding level (maintenance). After period of initial adaptation, the animals designated to received 2% of CW at concentrated one week passed receiving 1.5% CW in concentrated and one more week receiving 2% CW in concentrated for adaptation on the diet. The animals designated to receive 1% CW in concentrated and the treatment in maintenance started your diet immediately after the initial adaptation. At the end of that second week, call of second adaptation, all the animals were heavy, in fast of 16 hours, for beginning of the first experimental period. The animals in maintenance regime received the same diet supplied for the animals fed with 1% of CW at concentrated, in the equivalent amount to 1% of CW. The roughage was supplied at ease, being constituted of corn silage. The concentrate, in restricted amount, was formulated at base of ground corn, soybean meal, whole cottonseed, soybean hulls, urea/ammonium sulfate (9:1), sodium bicarbonate, magnesium oxide, common salt and mineral premix. The concentrate were formulated for that the same ration was offered the both treatments, changing only relationship corn/urea + ammonium sulfate allowing the diets to keep isonitrogenous (12.5% CP in the DM). The animals were maintained in individual stalls, with floor, concrete feeder and drinker, with total area of 30 m2, with 8 m2 of covered area. The experiment had total duration of 136 days, being 30 days of adaptation to the experimental conditions, 14 days of adaptation to the diet (2nd adaptation) and 84 days of experimental period. Were intermediate weighs, in fast of 16 hours, to the 28 and 56 days of performance. After the period of evaluation performance, started the slaughter of the animals. Like this, was evaluated the effect of genetic group and alimentary regime on quantitative and qualitative characteristics, physical and chemical composition of the gain, of the carcass and of the empty body and standard of deposition of tissues. Animals fed with larger concentrate level had larger (P<0.05) cold carcass weight (CCW), cold carcass dressing (CCD) and rib eye area/100 Kg of cold carcass (REA/100 kg) in relation to the small concentrate level. Except for cut of the top sirloin butt, there was not difference (P>0.05) in the feeding ad libitum for the yield of cuts. Crossbred animals presented larger (P <0.05) CCW that animals NE. The animals NA had larger (P<0.05) fat thickness (FT) and smaller REA/100 kg in relation to the animals NS. The trade cuts was not influenced (P>0.05) for the genetic group, except for the cut of the shoulder clod that had smaller (P<0.05) yield in the crossbred animals. The final pH was not influenced (P<0.05) for the treatments and it was inside of the appropriate patterns for export, below 6.0. The measures of REA and FT taken along the development of the animals detected the growth stage in that met. Crossbred animals and fed with larger concentrate level possess carcasses with more appropriate characteristics to the requirements of the import market, in a general way. Animals in maintenance presented larger (P<0.05) proportion of bones and muscle in the carcass and animals NE had larger muscle proportion and smaller (P<0.05) proportion of total fatty in the carcass that crossbreds animals. Animals NE and in maintenance present smaller (P<0.05) amount of total fat that crossbreds and fed ad libitum, respectively. The fat was deposited in larger proportion in the intermuscle fatty tissue, followed by the fatty of mesentery. The rate of deposition of tissues in the carcass was smaller in the animals NE and fed with 1% of concentrated (except for subcutaneous fatty tissue), in relation to the crossbreds animals and fed with 2% of concentrated, respectively. The rate of fat deposition in the adipose tissue of mesentery it was larger (P<0.05) in the animals NA and fed with 2% of concentrated in relation to NS and animals fed with 1% of concentrated respectively. Animals NS and NA presented more tender meat than the animals NE. The meat of animals fed with 1% and 2% of concentrated it lost more water (P<0.05) that the meat of the animals in maintenance during the thawing and in the total losses. During the cooking, there was difference (P<0.05) in the losses for drip loss for all the regimes, being the larger losses in that order: 1% of concentrated, 2% of concentrated and maintenance. The genetic group Nellore presented larger proportion of intermediate fibers (P<0.05) and lower proportion of oxidative fibers (P<0.05), the opposite was observed for the crossbred animals. There were difference (P<0.05), in the proportion of separated fibers in agreement with contractile characteristics, inside of genetic group. The animals Nellore had larger proportion of fibers of fast contraction and smaller proportion of fibers of slow contraction (P<0.05) in relation to the crossbred animals. Crossbred animals have more tender meat than the animals Nellore; however, all were inside of the pattern for the meat to be considered tender. Animals in restriction lost less water than animals fed ad libitum and the animals Nellore lost more water than the crossbred animals.
O setor produtivo de carne deve implementar tecnologias que produzam animais mais jovens, com características raciais que promovam carne de qualidade. A manipulação da dieta e o uso de cruzamento industrial são tecnologias de fácil acesso ao produtor. Foram utilizados 60 bovinos castrados de 18 meses, sendo 20 Nelore (NE), F1 Simental x Nelore , F1 Angus x Nelore com peso médio de 265,6±6,4 kg, 325,3±4,7 kg e 324,6±6,0 kg, respectivamente. O experimento foi em delineamento inteiramente casualizado, em esquema fatorial 3 x 3, sendo 3 grupos genéticos (Nelore, F1 Simental x Nelore, F1 Angus x Nelore) e três regimes alimentares (alimentação ao nível de mantença e ad libitum com 1% e 2% do peso corporal (PC) em concentrado na matéria natural da dieta),compondo, portanto, 9 tratamentos ( 6 repetições em cada grupo genético nos níveis de alimentação ad libitum (1% e 2%) e quatro repetições para o nível de alimentação restrito). Após período de adaptação inicial, os animais designados a receber 2% do PC em concentrado passaram uma semana recebendo 1,5% do PC em concentrado e mais uma semana recebendo 2% do PC em concentrado para adaptação à dieta. Os animais designados a receber 1% do PC em concentrado e o tratamento em mantença iniciaram sua dieta imediatamente após a adaptação inicial. Ao término dessa segunda semana, chamada de segunda adaptação, todos os animais foram pesados, em jejum de 16 horas, para início do primeiro período experimental. Os animais em regime de mantença receberam a mesma dieta fornecida para os animais alimentados com 1 % do PC em concentrado, na quantidade equivalente a 1 % do PC. O volumoso foi fornecido à vontade, sendo constituído de silagem de milho. O concentrado, em quantidade restrita, foi formulado à base de milho moído, farelo de soja, caroço de algodão, casca de soja, uréia/sulfato de amônio (9:1), bicarbonato de sódio, óxido de magnésio, sal comum e premix mineral. Os concentrados foram formulados para que a mesma ração fosse ofertada a ambos tratamentos, mudando apenas a relação milho/uréia+sulfato de amônia permitindo que as dietas se mantivessem isoprotéicas (12,5 % de PB na MS). Os animais foram mantidos em baias individuais, com piso, comedouro e bebedouro de concreto, com área total de 30 m2, dos quais 8 m2 de área coberta com telhas de amianto. O experimento teve duração total de 136 dias, sendo 30 dias de adaptação às condições experimentais, 14 dias de adaptação à dieta (2ª adaptação) e 84 dias de período experimental. Foram realizadas pesagens intermediárias, em jejum de 16 horas, aos 28 dias e 56 dias de desempenho. Após o período de avaliação do desempenho, iniciou-se o abate dos animais. Assim, avaliou-se o efeito de grupo genético e regime alimentar sobre características quantitativas, qualitativas, composição física e química do ganho, da carcaça e do corpo vazio e padrão de deposição de tecidos. Animais alimentados com maior nível de concentrado tiveram maior (P<0,05) peso de carcaça fria (PCF), rendimento de carcaça fria (RCF) e área de olho de lombo/100 Kg de carcaça fria (AOL/100 kg) em relação ao menor nível de concentrado. Exceto para o corte da alcatra, não houve diferença (P>0,05) na alimentação ad libitum para o rendimento de cortes. Animais cruzados apresentaram maior (P<0,05) PCF que animais NE. Os animais NA tiveram maior (P<0,05) espessura de gordura subcutânea (EGS) e menor AOL/100 kg em relação aos animais NS. O rendimento de cortes não foi influenciado (P>0,05) pelo grupo genético, exceto pelo corte da paleta que teve menor (P<0,05) rendimento nos animais cruzados. O pH final não foi influenciado (P<0,05) pelos tratamentos e ficou dentro dos padrões adequados para exportação, abaixo de 6,0. As medidas de AOL e EGS tomadas ao longo do desenvolvimento dos animais detectaram o estágio de crescimento em que eles se encontravam. Animais cruzados e alimentados com maior nível de concentrado possuem carcaças com características mais adequadas às exigências do mercado importador, de uma forma geral. Animais em mantença apresentaram maior (P<0,05) proporção de ossos e músculo na carcaça e animais NE tiveram maior proporção de músculo e menor (P<0,05) proporção de tecido adiposo total na carcaça que animais cruzados. Animais NE e em mantença apresentam menor (P<0,05) quantidade de gordura total que animais cruzados e alimentados ad libitum, respectivamente. A gordura foi depositada em maior proporção no tecido adiposo intermuscular, seguido do tecido adiposo de mesentério. A taxa de deposição de tecidos na carcaça foi menor nos animais NE e alimentados com 1% de concentrado (exceto para tecido adiposo subcutâneo), em relação aos animais cruzados e alimentados com 2% de concentrado, respectivamente. A taxa de deposição de gordura no tecido adiposo de mesentério foi maior (P<0,05) nos animais NA e alimentados com 2% de concentrado em relação aos NS e animais alimentados com 1% de concentrado, respectivamente. Animais NS e NA apresentaram carne mais macia que os animais NE. A carne de animais alimentados com 1% e 2% de concentrado perdeu mais água (P<0,05) que a carne dos animais em mantença durante o descongelamento e nas perdas totais. Durante a cocção, houve diferença (P<0,05) nas perdas por gotejamento para todos os regimes, sendo as perdas maiores nessa ordem: 1% de concentrado, 2% de concentrado e mantença. O grupo genético NE apresentou maior proporção de fibras intermediárias (P<0,05) e menor proporção de fibras oxidativas (P<0,05), o contrário foi observado para os animais cruzados. Houve diferença (P<0,05), na proporção de fibras separadas de acordo com características contráteis, dentro de grupo genético. Os animais NE tiveram maior proporção de fibras de contração rápida e menor proporção de fibras de contração lenta (P<0,05) em relação aos animais cruzados. Animais cruzados possuem carne mais macia que os animais NE; no entanto, todas estavam dentro do padrão para a carne ser considerada macia. Animais em restrição perderam menos água que animais alimentados ad libitum e os animais NE perderam mais água em relação aos animais cruzados.

Abstract:

We utilize a Poisson likelihood in a maximum likelihood statistical analysis to analyze X-ray spectragraphic data. Specifically, we examine four extragalactic supernova remnants (SNR). IKT 5 (SNR 0047-73.5), IKT 25 (SNR 0104-72.3), and DEM S 128 (SNR 0103-72.4) which are designated as Type Ia in the literature due to their spectra and morphology. This is troublesome because of their asymmetry, a trait not usually associated with young Type Ia remnants. We present Chandra X-ray Observatory data on these three remnants, and perform a maximum likelihood analysis on their spectra. We find that the X-ray emission is dominated by interactions with the interstellar medium. In spite of this, we find a significant Fe overabundance in all three remnants. Through examination of radio, optical, and infrared data, we conclude that these three remnants are likely not "classical" Type Ia SNR, but may be examples of so-called "prompt" Type Ia SNR. We detect potential point sources that may be members of the progenitor systems of both DEM S 128 and IKT 5, which could suggest a new subclass of prompt Type Ia SNR, Fe-rich CC remnants. In addition, we examine IKT 18. This remnant is positionally coincident with the X-ray point source HD 5980. Due to an outburst in 1994, in which its brightness changed by 3 magnitudes (corrsponding to an increase in luminosity by a factor of 16) HD 5980 was classified as a luminous blue variable star. We examine this point source and the remnant IKT 18 in the X-ray, and find that its non-thermal photon index has decreased from 2002 to 2013, corresponding to a larger proportion of more energetic X-rays, which is unexpected.

Abstract:
Energy is the biggest concern for any heterogeneous WSNs and achieving high energy efficiency is of paramount importance for the longevity of a heterogeneous WSNs. Communicating in- formation from the sensing region to the sink is a critical task in the entire operation of a heterogeneous WSNs. Such information needs to be reliably communicated, while avoiding any network congestion, from source to sink in order to ensure that application-specific Quality of Service objectives are met for any given scenario. This thesis developed several transport layer protocols to address the issues of congestion control, reliability assurance, simultaneously supporting heterogeneous traffic environment and energy efficiency for a heterogeneous WSNs.The first aim of the proposed research is to develop a congestion control scheme for a heterogeneous WSNs. The envisaged congestion control scheme has dual functionality. Firstly, it should be capable of handling the traffic heterogeneity and secondly, it intelligently assigns the source transmission rates and channel bandwidth for avoiding congested scenarios within the network, thereby avoiding any unnecessary packet retransmissions, due to packet drops caused by congestion. This produces high network good throughput, effective use of channel bandwidth, minimum E-2-E data packet latency etc. All the proposed transport layer protocol schemes e.g. End-to-End Reliable and Congestion Aware Transport Layer Protocol (ERCTP), Lightweight Congestion Aware Reliable Transport protocol (LCART) and Lightweight Congestion Aware Reliable Transport Protocol-implicit (LCARTi) are designed with this aim in mind.The second aim of the proposed research is to develop an intelligent reliability ensuring scheme capable of handling bidirectional reliability issues associated with data and control information flow within the heterogeneous WSNs. The design takes into account the variable nature of reliability assurance based on the nature of the traffic. For instance, multimedia flow is given a high reliability measure in comparison to scalar and non-event information flow, since the multimedia has a high retransmission cost. All the proposed transport layer protocol schemes such as ERCTP, LCART and LCARTi are designed in order to achieve this objective.The third aim of the proposed research is to develop a scheme that simultaneously handles the heterogeneous traffic flows within the same network. The proposed scheme has the intelligence to determine the nature of traffic and to allocate different bandwidth based on this nature in order to meet the stringent requirements as imposed by the application-specific QoS constraints like E-2-E data packet latency, high good throughput etc. All the proposed transport layer protocol schemes such as ERCTP, LCART and LCARTi are designed with this objective in mind.The fourth and final aim of the proposed research is to create a mechanism that merges the common functionalities of different layers of the WSNs communication stack in order to maximise energy efficiency. This involves finding the relationship between the transport and the lower MAC and wireless-physical layers of the WSNs communication stack. This merging will result in better utilization of network resources such as bandwidth, storage etc. and helps to achieve the objective of energy efficiency. Only the LCART and LCARTi designs achieve this proposed research aim.

Abstract:
The involvement of dynamical fluctuations in driving enzymatic processes is widely accepted. With respect to NQM tunnelling enzymes, the role of promoting motions in facilitating hydrogenic transfers is well studied. Few studies have however, specifically attributed, dedicated dynamical fluctuations characterised by their timescales and magnitudes, as a function of a reaction coordinate, to specific groups in a protein system. An effectively full suite of backbone resonance assignments were obtained for PETNR and on relevant ligand complexes. This provided an essential platform on which residue specific, backbone amide fluctuations were assessed. This thesis documents the application of pressure up to 1500 bar, in tandem with high resolution TROSY based NMR analysis, as a means of studying residue specific, conformer exchange perturbations. Residue specific amide compression profiles of the PETNR:FMN free enzyme system, and complexes with progesterone and tetrahydropyridine dinucleotides have been obtained. The binding of progesterone appears to induce conformational tightening of residues within the active site vicinity. The complexation of PETNR:FMN with tetrahydropyridine dinucleotides, appears to stimulate conformational shifts towards intermediate, and in some cases, slow exchange regimes in multiple residues about the active site vicinity. This is evidenced by extensive intensity attenuation of 1H-15N TROSY resonances, on the binding of tetrahydropyridine dinucleotides at 1 bar pressure, and on going from 1 bar to 1500 bar pressure. Multiple regions of sequence, spatially clustering about the active site vicinity within a 10 Å sphere of the FMN binding pocket, display appreciable sensitivity to ligand binding. Differential responses of residues to the application of high pressure between complexes was noted within segments of these regions. A region of sequence, named the β-hairpin flap displays significant differential compression profiles between the PETNR:FMN free enzyme system, and associated progesterone and tetrahydropyridine dinucleotide complexes. A role in mediating ligand engagement is proposed for R130 and R142 in the β-hairpin flap. A central hydrogen bonding network, perhaps constituting a putative proton wire in the active site of the PETNR:FMN:Progesterone complex, has been identified that could enable the shuttling of protons following catalytic protonation of oxidative substrate. The resonance response behaviour of G185 acts as a sensitive reporter on the formation of these interactions, revealed by an interrogation of the differences in chemical shift changes on progesterone binding, and in response to high pressure. The recruitment of high resolution crystallographic data sets readily supported a structural and dynamical interpretation of the observed chemical shift responses to ligand binding at 1 bar pressure, and on the application high pressure. A definitive atomistic identification of fast motion contribution to activation barrier compression was not obtained. Nevertheless, detailed, residue specific amide compression profiles, and shifts in backbone amide conformational exchange regimes in response to ground state ligand binding, and at high pressure, have been catalogued in the PETNR:FMN free enzyme system. These dynamical profiles in the free enzyme are contrasted against comparative, residue specific observations in analogue complexes of the oxidative and reductive half reactions of PETNR.

Abstract:
The years 2015 and 2016 saw dynamic and significant developments in international investment law and arbitration. This chapter discusses some notable decisions and developments in the case law that occurred during this period. It focuses on decisions that: are novel; address topical issues; may impact subsequent case law as a result of, amongst others, the interpretation of multilateral treaties or the development of legal doctrines; were particularly high-profile or garnered significant public attention; and/or may shape the development of the investor–state arbitration regime. The chapter is divided into six parts: security for costs; disclosure of third-party funding; strategic investment structuring to benefit from investment treaty protection; the first decisions issued in the Energy Charter Treaty (ECT) disputes against Spain; host states' right to regulate; and the enforcement and set-aside of arbitral awards.

Full text
Abstract:
Since the first edition of this book appeared (2000), there has been a spectacular development in the use of calorimeters for measuring natural phenomena, such as the detection of ultra-high-energy cosmic rays, or neutrinos from sources such as the Sun, the Earth’s atmosphere, or the Universe at large. This development is documentsed in this chapter. It starts with a section on SuperKamiokande, which has already collected two Nobel prizes, and its envisaged successor HyperKamiokande, which is designed to be sensitive to neutrinos from supernova explosions in the Andromeda galaxy. On an even larger scale, several sections of the Mediterranean sea as well a cubic kilometre of ice under the South Pole are looking for neutrinos from outer space, and are detecting other interesting phenomena as well. The Earth’s atmosphere is used as a huge calorimeter by experiments such as Auger and KASKADE-Grande. Combined with dedicated Cherenkov telescopes, such as HESS, these experiments have provided important new insights in mysterious aspects of the high-energy component of the cosmic rays that bombard our planet, such as the knees in the PeV-EeV region and the GZK cutoff.

Full text
Abstract:
The Tibetan Plateau (TP) is subjected to strong interactions among the atmosphere, hydrosphere, cryosphere, and biosphere. The Plateau exerts huge thermal forcing on the mid-troposphere over the mid-latitude of the Northern Hemisphere during spring and summer. This region also contains the headwaters of major rivers in Asia and provides a large portion of the water resources used for economic activities in adjacent regions. Since the beginning of the 1980s, the TP has undergone evident climate changes, with overall surface air warming and moistening, solar dimming, and decrease in wind speed. Surface warming, which depends on elevation and its horizontal pattern (warming in most of the TP but cooling in the westernmost TP), was consistent with glacial changes. Accompanying the warming was air moistening, with a sudden increase in precipitable water in 1998. Both triggered more deep clouds, which resulted in solar dimming. Surface wind speed declined from the 1970s and started to recover in 2002, as a result of atmospheric circulation adjustment caused by the differential surface warming between Asian high latitudes and low latitudes.The climate changes over the TP have changed energy and water cycles and has thus reshaped the local environment. Thermal forcing over the TP has weakened. The warming and decrease in wind speed lowered the Bowen ratio and has led to less surface sensible heating. Atmospheric radiative cooling has been enhanced, mainly through outgoing longwave emission from the warming planetary system and slightly enhanced solar radiation reflection. The trend in both energy terms has contributed to the weakening of thermal forcing over the Plateau. The water cycle has been significantly altered by the climate changes. The monsoon-impacted region (i.e., the southern and eastern regions of the TP) has received less precipitation, more evaporation, less soil moisture and less runoff, which has resulted in the general shrinkage of lakes and pools in this region, although glacier melt has increased. The region dominated by westerlies (i.e., central, northern and western regions of the TP) received more precipitation, more evaporation, more soil moisture and more runoff, which together with more glacier melt resulted in the general expansion of lakes in this region. The overall wetting in the TP is due to both the warmer and moister conditions at the surface, which increased convective available potential energy and may eventually depend on decadal variability of atmospheric circulations such as Atlantic Multi-decadal Oscillation and an intensified Siberian High. The drying process in the southern region is perhaps related to the expansion of Hadley circulation. All these processes have not been well understood.

Abstract:
India’s traditional focus on economic and community-based ties with the Persian Gulf has been complemented in the twenty-first century with a dramatic upswing in political, defence, security, energy, and economic linkages with the countries of the region. Developments in the Gulf after the Arab Spring—centred around the Saudi–Iran divide on sectarian and strategic bases, competition for space and influence among various Islamist groups, and challenges to the traditional domestic structures within GCC countries—have created considerable turbulence in the regional security scenario. Given its high stakes in the region, Indian foreign policy faces a new imperative: defining and realizing a new security architecture in the Persian Gulf that would embrace all players, regional and extra-regional, in association with other major Asian powers which share India’s interests in Gulf stability.

Abstract:
The knee is one of the main load-bearing joints of the body, and injuries to it can involve damage to the joint or articular surfaces, or fractures to the long bones in case of high-energy trauma. The position of the contralateral leg can cause difficulty in positioning for imaging, but good positioning and technique should allow demonstration of the region for intervention. This chapter covers a selection of orthopaedic procedures involving the distal femur and knee, covering distal femoral plating and LISS plates, tension band wiring of the patella, and cerclage wiring of the patella. Each procedure includes images that demonstrate the position of the C-arm, patient, and surgical equipment, with accompanying radiographs demonstrating the resulting images.

Abstract:
This chapter explores how sound systems place electronic sounds in a social context, eliciting powerful affective experiences that are framed by conceptual meaning. The chapter begins by tracing the origins of the sound system culture and dub-reggae of Jamaica. This approach, which prioritizes DJ performances over ‘live’ musicians, would prefigure the electronic dance music culture of the 1980s and 1990s. Exploring this area, this chapter examines how the design of Chicago house and Detroit techno provided high-energy dance experiences that reflected the ethos of the respective sub-cultures. Later, in the UK rave scene, breakbeat hardcore, drum & bass, and ambient house each used sound design to support an accelerated youth-culture fuelled by ecstasy, delivering trance-like experiences framed by conceptual meaning. In the global Goa trance and psy-trance scenes, this capability is explicitly characterized as ‘technoshamanic’, and the DJ as a ‘master of ecstasies’.

Abstract:
AbstractWe present a simple parameterization for coarse-resolution ocean models. To replace computationally expensive high-resolution ocean models, we develop a computationally cheap parameterization for coarse-resolution models based solely on the modification of the viscosity term in advection equations. It is meant to reproduce the mean quantities like pressure, velocity, or vorticity computed from a high-resolution reference solution or using observations. We test this new parameterization on a double-gyre quasi-geostrophic model in the eddy-permitting regime. Our results show that the proposed scheme improves significantly the energy statistics and the intrinsic variability on the coarse mesh. This method shall serve as a deterministic basis model for coarse-resolution stochastic parameterizations in future works.

Full text
Abstract:
AbstractThis chapter argues that domestic politics plays a significant role in shaping Sino-Russian relations. Domestic political factors strengthen certain trends in the relationship and, more occasionally, generate obstacles. In structural terms, the growing similarity of political systems, characterized by a high degree of centralization of power in leaders’ hands and the rising crackdown on dissent, shapes the threat assessment. The Russian ruling regime is not challenged by Beijing, hence an increase in China’s power and influence. While disadvantageous geopolitically, it does not pose a threat to regime security and regime survival in the Kremlin. Domestic actors have contributed to Russia’s policy towards China in two ways: by influencing the leadership’s threat assessment and by implementing particular policies. In some areas, such as energy cooperation, a privileged position on behalf of certain actors enables them to promote closer cooperation with China. There is no openly anti-Chinese lobby within the ruling elite and its supporters. More often than not, domestic politics act as a facilitating factor, which mitigates systemic pressures related to China’s rise and growing asymmetry between Russia and China and creates a conducive environment for bilateral cooperation with China in certain sectors.

Abstract:
Abstract An international consortium of more than 150 organizations worldwide is studying the feasibility of various future particle colliders to expand our understanding of the inner workings of the Universe. At the core of the Future Circular Collider (FCC) study is the design of a 100 km long circular particle collider infrastructure that could extend CERN’s current accelerator complex with an integral research program that spans 70 years. The first step would be an intensity-frontier electron-positron collider allowing to study with precision the Higgs couplings with many of the Standard Model particles and search with high-precision for new physics while the ultimate goal is to build a proton collider with a c.m.s collision energy seven times larger than the Large Hadron Collider. Hosted in the same tunnel and profiting from the new infrastructure, FCC-hh would allow to explore a new energy regime where new physics may be at play.

Full text
Abstract:
n line with Scottish Net Zero targets and the national strategy for a Just Transition, the Northeast of Scotland is transforming towards a low carbon future with a number of high-profile industry and policy initiatives. With the region home to global energy companies and historical high levels of energy sector employment, the narrative on transition is predominantly framed within an industrial and technological context, including narratives on new opportunities in green jobs, green industrial development, technical innovation and new infrastructure to support energy transition. As the energy landscape shifts in the North-East of Scotland, the impacts will be felt most keenly in communities from shifts in employment to changes to local supply chains. It is important to note that Net Zero ambitions will also change the nature and structure of communities in the region, for those within a shifting oil and gas industry and those without. A just transition ensures that all voices are heard, engaged and included in the process of change, and that communities, including those who have benefited and those who have not, have a stake in determining the direction of travel of a changing society and economy of the North-east. As a result, there is a need for a community-oriented perspective to transition which discusses a range of values and perspectives, the opportunities and resources available for transition and how communities of place can support the process of change toward Net Zero. Social transformation is a key element of a just transition and community engagement, inclusion and participation is embedded in the principles laid down by the Just Transition Commission. Despite this high-level recognition of social justice and inclusion at the heart of transition, there has been little move to understand what a just transition means in the context of local communities in the NorthEast. This project aims to address this imbalance and promote the ability of communities to not only engage but to help steer net zero transitions. It seeks to uncover and build a stronger local consensus about the vision and pathways for civil society to progress a just transition in the Northeast of Scotland. The project aims to do this through bringing together civil society, academic, policy and business stakeholders across three interactive workshops to: 1. Empower NE communities to engage with the Just Transition agenda 2. Identify what are the key issues within a Just Transition and how they can be applied in the Northeast. 3. Directly support communities by providing training and resources to facilitate change by working in partnership. The project funding supported the delivery of three professionally facilitated online workshops that were held over 2021/22 (Figure 1). Workshop 1 explored the global principles within a just transition and how these could apply to the Scottish context. Workshop 2 examined different pathways and options for transition in the context of Northeast Scotland. Workshop 3, in partnership with NESCAN explored operational challenges and best practices with community participants. The outcomes from the three workshops are explored in detail.

Full text
Abstract:
Earth’s high latitudes are projected to experience warmer and wetter summers in the future but ramifications for soil thermal processes and permafrost thaw are poorly understood. Here we present 2750 end of summer thaw depths representing a range of vegetation characteristics in Interior Alaska measured over a 5-year period. This included the top and third wettest summers in the 91-year record and three summers with precipitation close to mean historical values. Increased rainfall led to deeper thaw across all sites with an increase of 0.7 ± 0.1 cm of thaw per cm of additional rain. Disturbed and wetland sites were the most vulnerable to rain-induced thaw with ~1 cm of surface thaw per additional 1 cm of rain. Permafrost in tussock tundra, mixed forest, and conifer forest was less sensitive to rain-induced thaw. A simple energy budget model yields seasonal thaw values smaller than the linear regression of our measurements but provides a first-order estimate of the role of rain-driven sensible heat fluxes in high-latitude terrestrial permafrost. This study demonstrates substantial permafrost thaw from the projected increasing summer precipitation across most of the Arctic region.

Abstract:
Achieving universal electrification in sub-Saharan Africa requires creative solutions. Renewable mini-grids are a promising technology to electrify remote communities with a substantial productive demand, mainly from agro-processing. Mini-grids have experienced fast growth and there are now around 2,200 systems in the sub-Saharan Africa region. However, their economic case in the sub-continent is unclear. Most mini-grids are struggling not only to obtain a profit but also to recover costs. This Research Report describes the case of a private company in Tanzania implementing a business model for mini-grids that promotes productive uses of energy to achieve financial sustainability (the ‘Keymaker model’). A group of researchers worked jointly with the mini-grid developer to procure equipment for fish processing activities, support local entrepreneurs to use electricity productively, and to document and learn from the process. Although the business model was ultimately unsuccessful – facing high regulatory risks, high initial tariffs required to recover costs, and complex management of agro-processing activities – the project offers useful lessons and considerations for future efforts to promote mini-grids, and how public–private partnerships can help improve affordability and reduce regulatory risks.

Abstract:
The relationship between Korea and Latin American and the Caribbean has come a long way. As the two economies embraced trade with one another in the early 1990s, their connection went from being irrelevant to being a wealth machine. Bilateral trade grew at an impressive annual rate of 11.5%reaching a record high in 2021. The trade boom was followed by US$26 billion in investments by Korean firms in the region since 2000. Despite this meteoric rise, lingering trade barriers remain, and new challenges are emerging from a string of disruptive shocks to the global economyprotectionist backlashes; growing and interrelated sanitary, food, energy, and climate crises; and a fast-moving “digital transformation.” This monograph argues that, despite the challenges, both economies have a set of policies, institutions, and comparative advantages that, if reinforced and leveraged by trade and cooperation, can turn these shocks into bilateral and global opportunities for inclusive and sustainable growth.

Abstract:
The geophysical data sets available for the western Churchill Province have had a bearing on the understanding of its structure, evolution and metal endowment. New data were acquired and interpreted during the Geo-mapping for Energy and Minerals (GEM) Program (2008-2020). Regional, high-resolution aeromagnetic, and targeted gravity and magnetotelluric surveys were collected in GEM, in conjunction with geological mapping projects, in order to provide control on bedrock features beneath widespread glacial overburden and flat-lying sedimentary basins. Quantitative estimates of three-dimensional geometry were obtained in key areas through geophysical models integrating the geophysical characteristics with local rock property measurements. These geophysical data sets contributed to new knowledge and interpretations in three related research fields: 1) location and nature of Rae cratonmp;gt;'s boundaries within the western Churchill Province; 2) definition of internal Rae architecture; and 3) identification of reactivated structures controlling gold and uranium mineralization. The new data, models and emerging tectonic and metallogenic frameworks will serve as guides for future exploration in this remote, complex, challenging region.

Abstract:
Highlights • Individual investors prefer to have an investment with high ROI rather than a low-profit investment with environmental and social benefits. • Males invest and donate more money than females in terms of quantity and frequency. • People with a level of education above an associate degree (D3) have a significantly higher level of willingness to invest and donate to green project, compared to people with a lower level of education. • In general, people with a higher income level have a higher willingness to invest. However, there is no proof on the relationship between level of income and willingness to donate. • The age increases have a positive correlation with the willingness to invest in green project. Nevertheless, people >44 years old are more interested in donating than investing. • The younger generation (<44 years) tends to pick higher returns and short payback periods compared to the older generations (>44 years). • The respondents tend to invest and donate to the project located in the frontier, outermost, and least developed region (3T) even though the majority of the respondents are from Java, Madura, and Bali. • A social project such as health and education are preferable projects chosen by the respondents to invest and donate to, followed by the conservation, climate crisis, region’s welfare, and clean energy access. • Clean energy has not been seen as one of the preferred targets for green project investors and donors due to the poor knowledge of its direct impact on the environment and people’s welfare. • The average willingness to invest and donate is IDR 10,527,004 and IDR 2,893,079/person/annum with desired return on investment (ROI) and payback period (PP) of 5–8% 24 months, respectively. • Respondents prefer to donate more money to reward donations than donations without reward. • There is an enormous potential of crowdfunding as green project alternative financing, including renewable energy. The total investment could reach up to IDR 192 trillion (USD 13.4 billion)/annum and up to IDR 46 trillion (USD 3.2 billion)/annum for donation. • The main bottlenecks are poor financial literacy and the lack of platforms to facilitate public participation. • COVID-19 has decreased willingness to pay and invest due to income reduction and the uncertain economic recovery situation. However, it makes people pay more attention to the sustainability factor (shifting paradigm in investment).

Abstract:
To increase our food security in Västerbotten we will need to become more self-sufficient of both energy, feed and nutrients that are now imported to the region. Biogas production from different waste streams is one solution to this. Biogas is produced using biowaste or sewage sludge as substrate in the major cities Umeå and Skellefteå. Biogas systems offer a range of benefits to society. Biogas production is currently prized for its climate benefits when replacing fossil fuels for the production of heat, electricity and vehicle gas, but at Bothnia Nutrient Recycling we have studied how to use the digestate, i.e. the residual product of production, as fertilizer in agriculture. We have been working to improve profitability for biogas producers and develop sustainable products from recycled nutrients, like phosphorus and nitrogen. Improving the uses for digestate increases self-sufficiency in agriculture and contributes to a circular economy. We conducted three agricultural demonstration experiments in collaboration with agricultural high schools in Finland and Sweden to introduce digestate and digestate products to the future farmers in the regions. We found that it may be possible to replace cattle slurry with compost when growing maize despite the low levels of nitrogen, N, available to plants in the compost. In barley, NPK fertilizers gave the highest yield. Digestate from HEMAB and sludge biochar supplemented with recycled ammonium sulphate gave a smaller yield but higher than unfertilized crop. Digestate from a dry digestion biogas plant in Härnösand was better suited to barley than to grass because in an experiment on grass ley the viscous fertilizer did not penetrate the grass and did not increase the growth of the grass. Fertilizer effects on crop quality were small. There was no increased uptake of heavy metals in barley after fertilization with digestate or digestate products compared to NPK fertilization. These demonstration experiments show that more thorough scientific experimentation is needed as a foundation for recommendations to farmers. The amounts of nitrogen and phosphorous in digestate from Västerbotten that could become used as fertilizer were modelled. It showed that if sewage sludge digestate is used to make sludge biochar and ammonium sulphate and the other available digestates are used directly in agriculture, the entire phosphorous demand but only a small part of the nitrogen demand in the county, could be covered. Thus, to achieve a true circular food production, development and increase of both the waste handling sector and agriculture is needed.
