Abstract:
Ecosystem services are fundamental in supporting human well-being which is a core component of sustainability. Understanding the relationship between ecosystem services (ESs) and human well-being (HWB) in a changing landscape is important to implement appropriate ecosystem management and policy development. Combining with demographic, economic, and cultural factors, their land use are the elements linking ESs and HWB at fine scale. Within this context, the purpose of this study is to evaluate household HWB changes in the past decade, and understand the relationship between demographic factors, land use, ESs, and HWB in the social-ecological landscapes of Uxin, in Inner Mongolia. Our results indicate that: the levels of HWB of local herder families were slightly improved from 2007 to 2016; changes in family demographic factors enhanced their land use intensity, resulting in an increased supply capacity of ecosystems and improved HWB; in addition, regulating services contributed more to HWB than provisioning services. The results of this study can help improve the understanding of the relationship between ESs and HWB, and provide valuable information to policy-makers to maintain particular ESs or to improve HWB.

Abstract:
Identifying how policy, socioeconomic factors, and environmental factors influence changes in human well-being (HWB) and conservation efficiency is important for ecological management and sustainable development, especially in the Giant Panda National Park (GPNP). In this study, we systematically analyzed the differences in the conservation status of the giant panda habitat and changes in HWB over 15 years in the GPNP, which includes six mountain sites, Minshan (MS), Qionglai (QLS), Xiaoxiangling (XXL), Liangshan (LS), Qinling (QL), and Daxiangling (DXL). Redundancy analyses were used to determine the factors contributing (policy, socioeconomic factors, and environmental factors) to HWB and giant panda habitat conservation (HC). In addition, using a structural equation model (SEM), we investigated the relationship between the aforementioned three factors and their direct and indirect effects on HWB and HC. The results indicated that there was spatiotemporal heterogeneity of HWB and HC in our study area. There was an increasing number of plant species as well as an increased number of giant panda in GPNP. Generally, HWB in 2015 showed an increasing trend compared with that in 2000. Socioeconomic factors (23.6%) have the biggest influence on HWB and HC, followed by policy (23.2%) and environmental factors (19.4%). Conservation policy had a significantly positive influence on HWB (0.52), while it negatively influenced HC (−0.15). Socioeconomic factors significantly negatively influenced HWB (−0.38). The formulation and implementation of policies to promote economic development will contribute to the protection of giant pandas and their habitat. Our results provide insight on the conservation status of the giant panda habitat, HWB, and factors influencing them in different mountain sites in the GPNP, as well as having implications for the future management of the GPNP.

Abstract:
The effect of hot-water blanching (HWB) on drying characteristics and product qualities of dried apple slices with the novel integrated freeze-drying (NIFD) process was investigated by comparing with 3 different FD methods. Compared with the NIFD process without HWB pretreatment (VF-FD), the NIFD process with HWB pretreatment (HWB-VF-FD) resulted in a significantly higher mass loss and more sufficient freezing in vacuum-frozen samples, significantly higher rehydration ratio (RR), higher shrinkage ratio (SR), smaller Vitamin C (VC) content and lower hardness and better apparent shape in freeze-dried samples, and fewer change to the color of the dried or rehydrated samples (p<0.05). Compared with the conventional FD process with HWB pretreatment (HWB-PF-FD), HWB-VF-FD cost significantly less processing time and FD time and obtained significantly higher RR (p<0.05), almost the equivalent SR, VC content, and hardness, and similar appearance in dried samples. The microstructure of apple cell tissues was analyzed by transmission electron microscopy and scanning electron microscopy to interpret the above differences in drying characteristics and product qualities. The results suggested that the NIFD process of apple slices with HWB pretreatment was a promising alternative method to decrease drying time, achieve similar product quality, and simplify the process steps of the conventional FD technology.

Abstract:
Pine bark (PB) and composted hardwood bark (HWB) were combined into 5 media. Particle size distribution, total porosity, air space, moisture retention characteristics, and bulk density were determined for each medium. Four commercial fertilizers were applied and substrate nitrogen levels, pH, % foliar nitrogen and top dry weight were determined for Ilex x ‘Nellie R. Stevens’ holly. Pine bark had approximately 84% of the particles between 4.75 and 1.0 mm (0.19 and 0.04 in). As HWB was added in 25% increments (by vol) the percent weight of particles in this range decreased. HWB increased bulk density, but did not significantly change total porosity. Hardwood bark and the 1:3 PB:HWB (v/v) medium held more water than other media. Nursery Special raised pH in all media treatments. Plants treated with SulfurKote tended to have the highest foliar nitrogen content. The Sierrablen in PB and SulfurKote in 3 PB:1 HWB and 1 PB:1 HWB (v/v) and HWB produced the greatest top dry weight.

Abstract:
As society strives to transition towards more sustainable development pathways, it is important to properly conceptualize the link between biodiversity (i.e. genes, traits, species and other dimensions) and human well-being (HWB; i.e. health, wealth, security and other dimensions). Here, we explore how published conceptual frameworks consider the extent to which the biodiversity–HWB links are being integrated into public discourse and scientific research and the implications of our findings for sustainable development. We find that our understanding has gradually evolved from seeing the value of biodiversity as an external commodity that may influence HWB to biodiversity as fundamental to HWB. Analysis of the literature trends indicates increasing engagement with the terms biodiversity , HWB and sustainable development in the public, science and policy spheres, but largely as independent rather than linked terms. We suggest that a consensus framework for sustainable development should include biodiversity explicitly as a suite of internal variables that both influence and are influenced by HWB. Doing so will enhance clarity and help shape coherent research and policy priorities. We further suggest that the absence of this link in development can inadvertently lead to a ratcheting down of biodiversity by otherwise well-meaning policies. Such biotic impoverishment could lock HWB at minimum levels or lead to its decline and halt or reverse progress in achieving sustainable development.

Abstract:
Cryosphere services (CSs) refer to various benefits that humans directly or indirectly obtain from the cryosphere, which makes significant contributions to human well-being (HWB). To facilitate such research, we first present a classification system for conceptualizing, monitoring and assessing CSs based on the current process-based understanding of their nature and sustainability. Specifically, the CSs are grouped into five major categories (provisioning, regulating, cultural, bearing and supporting services) and 18 sub-categories. Then we provide a detailed overview on formation, current status and anticipated future changes of the identified types of the services, and their impact on HWB. Finally, the spatio-temporal scales, the links of the services with HWB and climate-dependence are further discussed. The research of CSs adopt interdisciplinary approach to address the formation mechanisms of CSs and their dynamic relationships with HWB, which is poised to provide a better understanding of the cryosphere’s role in human society and help enhance socio-ecological sustainability and HWB over cryosphere-affected areas. Notably, most CSs have been deteriorating under global warming and cryosphere shrinkage, further leading to negative impacts on associated HWB. Therefore, great attention should be paid to the changes in CSs and their cascading risks.

Abstract:
Background: There is a growing interest in research investigating the association between green space (GS) and mental health and wellbeing (HWB), in order to understand the underlying mechanisms. Accordingly, there is a need to map the literature and create an overview of the research. Methods: A scoping review approach was used to map literature on GS, including context and co-exposures (the GS exposome), and their associations with mental HWB. The review considers mental HWB definitions and measurements and how GS is characterized. Furthermore, the review aims to identify knowledge gaps and make recommendations for future research. Results: We identified a great diversity in study designs, definitions, outcome measures, consideration of the totality of the GS exposome, and reporting of results. Around 70% of the 263 reviewed studies reported a positive association between some aspect of GS and HWB. However, there is a limited amount of research using randomized controlled crossover trails (RCTs) and mixed methods and an abundance of qualitative subjective research. Conclusions: The discords between study designs, definitions, and the reporting of results makes it difficult to aggregate the evidence and identify any potential causal mechanisms. We propose key points to consider when defining and quantifying GS and make recommendations for reporting on research investigating GS and mental HWB. This review highlights a need for large well-designed RCTs that reliably measure the GS exposome in relation to mental HWB.

Abstract:
Objective Autologous articular cartilage (AC) harvested for repair procedures of high weight bearing (HWB) regions of the femoral condyles is typically obtained from low weight bearing (LWB) regions, in part due to the lack of non-destructive techniques for cartilage composition assessment. Here, we demonstrate that infrared fiber optic spectroscopy can be used to non-destructively evaluate variations in compositional and mechanical properties of AC across LWB and HWB regions. Design AC plugs ( N = 72) were harvested from the patellofemoral groove of juvenile bovine stifle joints, a LWB region, and femoral condyles, a HWB region. Near-infrared (NIR) and mid-infrared (MIR) fiber optic spectra were collected from plugs, and indentation tests were performed to determine the short-term and equilibrium moduli, followed by gravimetric water and biochemical analysis. Results LWB tissues had a significantly greater amount of water determined by NIR and gravimetric assay. The moduli generally increased in tissues from the patellofemoral groove to the condyles, with HWB condyle cartilage having significantly higher moduli. A greater amount of proteoglycan content was also found in HWB tissues, but no differences in collagen content. In addition, NIR-determined water correlated with short-term modulus and proteoglycan content ( R = −0.40 and −0.31, respectively), and a multivariate model with NIR data was able to predict short-term modulus within 15% error. Conclusions The properties of tissues from LWB regions differ from HWB tissues and can be determined non-destructively by infrared fiber optic spectroscopy. Clinicians may be able to use this modality to assess AC prior to harvesting osteochondral grafts for focal defect repair.

Abstract:
In 2010, schools in Scotland implemented a new curriculum, a Curriculum for Excellence, and for physical education (PE), this represented a move from the ‘Expressive Arts’ to ‘Health and Wellbeing’ (HWB). To understand this new position, we explored the thoughts of those who were directly involved in the construction of the policy text for PE within HWB ( n = 10). All of the participants supported the position of PE within HWB, accepting that PE has an important role to play in improving pupils’ health and wellbeing, although there was some concern that teachers might misinterpret the role of PE within HWB. However, all of the participants believed that this new position for PE would encourage other professionals to value PE more highly. We conclude by suggesting that there should be a greater involvement of teachers in the reform process so that future curricular innovations are more closely aligned with the knowledge and practice of teachers. This may enable them to understand policy more clearly and implement policy more effectively.

Abstract:
The nanoindentation method was applied to determine the elastic modulus and hardness of knee articular cartilage. Cartilage samples from both high weight bearing (HWB) and low weight bearing (LWB) femoral condyles were collected from patients diagnosed with osteoarthritis (OA). The mean elastic modulus of HWB cartilage was 4.46 ± 4.44 MPa in comparison to that of the LWB region (9.81 ± 8.88 MPa, p < 0.001). Similarly, the hardness was significantly lower in HWB tissue (0.317 ± 0.397 MPa) than in LWB cartilage (0.455 ± 0.434 MPa, p < 0.001). When adjusted to patients’ ages, the mean elastic modulus and hardness were both significantly lower in the age group over 70 years (p < 0.001). A statistically significant difference in mechanical parameters was also found in grade 3 and 4 OA. This study provides an insight into the nanomechanical properties of the knee articular cartilage and provides a starting point for personalized cartilage grafts that are compatible with the mechanical properties of the native tissue.

Abstract:
The project is for the central building of a community center used by the communities of Blacksburg and Christiansburg. The building is a space configured as a hub that uses axes to determine entering, exiting and vertical movement. The hub configuration of the building is in concentric rings around the atrium in both space and materials. As materials were brought into the building, they enhanced the strong axial configuration and emphasized the layers surrounding the central hub space of the atrium. There are two pairs of axes in the building. The entrance axes are perpendicular to the faces of the building and provide lines of sight through it. They also establish the paths of entering and exiting the building. The diagonal axes regulate the vertical movement throughout the building.

Abstract:
In this study, we propose a two-phase solution approach for approximating the efficient frontier of a bicriteria hub location problem. We develop an evolutionary algorithm to locate the hubs on the network as the first phase. In the second phase, we develop a bounding procedure based on dominance relations and using the determined bounds, we solve the allocation subproblem for each located hub set. The two-phase approach is tested on the Australian Post data set and it is observed that our approach approximates the entire efficient frontier well. In addition, we suggest an interactive procedure to find the solutions that are in the decision maker&rsquo
s preferred region of the solution space. In this procedure, we progressively incorporate the preferences of the decision maker and direct the search towards the preferred regions. Based on some computational experiments, it is observed that the interactive procedure converges to the preferred regions.

Abstract:
Al giorno d'oggi lavoriamo con quantità di dati impensabili fino a pochi anni fa. È possibile trovare i centri nevralgici di dati rappresentati sotto forma di un grafo pesato? Usando una recentissima teoria matematica che mira a slegare la persistenza dall'omologia persistente è possibile studiare i grafi pesati nel dominio della persistenza e individuarne i centri nevralgici. Tale teoria viene applicata in questo lavoro a grafi pesati estendendola con la definizione di particolari funzioni di persistenza che usiamo per analizzare tre reti. Dopo aver formalizzato l'idea intuitiva di hub in una rete definendo gli steady hub e i ranging hub, sperimentiamo la teoria descritta sulle seguenti reti: la rete dei collegamenti tra aeroporti degli Stati Uniti d'America, la rete delle relazioni tra i personaggi de Les Misérables e la rete delle lingue ufficiali dell'Unione Europea. Questi esempi che coprono campi estremamente differenti mirano a dare un'indicazione sulla generalità del metodo proposto.

Abstract:
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2003.
Includes bibliographical references (leaves 103-107).
This thesis introduces the Korean hub strategy and evaluates its viability. For benchmarking analysis, two best practices - the Netherlands and Singapore, are compared with Korea. Competition issues are also studied with two potential contenders - Hong Kong and China, in the Northeast Asian hub race. To mount the level of advanced countries and to cope with the explosive economic growth of China, the Korean government sets up an ambitious plan; being the most successful business hub in Northeast Asia. Its strategic scheme is divided into two categories - logistics hub and business center. For years, the Netherlands and Singapore have dominated as the regional hub with the unique role. The Netherlands focuses on the logistics in the Europe with solid regional economic cooperative system and strategic flexibility, while Singapore has had much attention to be the leading regional business hub in the Southeast Asia with strong government driven policy and the attractive national character - openness. With favorable regional economic environment and the China growth factors, in the Northeast Asian hub competition, Korea tries to grasp competitive advantage with relatively superior geographical location, technological advance and resourceful manpower. However, Hong Kong and China also have spurred their efforts to take advantage in the hub competition. With a pro-foreign environment and sound infrastructure, Hong Kong has already gained a leading position in the race. Meanwhile, China has an immense domestic demand and blazing speed of growth as strong merits to compete. To get a chance of success in the competition, Korea should overcome some critical barriers such as much entangled economic environment that might disturb regional economic cooperation, the weak level of competitive advantages in the various range of attributes that Korea possess, and currently risky political status in Korean peninsula that is caused by nuclear brinkmanship of North Korea. Unfortunately, considering overall competencies, Korea cannot offer any obvious credibility about their comprehensive capability to deal with those obstacles effectively and win the competition in the current frame of analysis. Therefore, the outlook of the Korean hub strategy is unclear and the viability of that also seems to be doubtful.

Abstract:
Industrial kitchens consume significant amounts of energy, largely in the form of heat production by cooking and cleaning equipment, which requires removal by the facility’s heating, ventilating, and air conditioning (HVAC) system. One potential means to improve the energy efficiency of industrial kitchens lies in the use of waste energy recovery of hot wastewater from an industrial-scale dishwasher. Examination of an on-campus dining facility suggests that waste heat recovery can occur at the facility gas hot water heater (HWH) and the dishwasher electric hot water booster (HWB). This study suggests that waste heat recovery is more financially viable in existing construction at the electric HWB, despite yielding less recovered heat than the gas HWH. A payback period of approximately two years is calculated for the installation of a 146 kW shell-and-tube heat exchanger. The corresponding annual source pollution reduction is approximately 13 kg of SO2, 6.5 kg of NOx, and 6.5 metric tons of CO2. However, new construction projects in similar building configurations could also include HWH heat recovery, resulting in a similar payback period but with more substantial annual source pollution reduction values: 14 kg of SO2, 33 kg of NOx, and 38 metric tons of CO2.

Abstract:
Worldwide concerns of air quality and climate change have made environmental protection one of the most critical issues in aviation today. NASA’s current Fundamental Aeronautics research program is directed at three generations of aircraft in the near, mid and far term, with initial operating capability around 2015, 2020, and 2030, respectively. Each generation has associated goals for fuel burn, NOx, noise, and field-length reductions relative to today’s aircrafts. The research for the 2020 generation is directed at enabling a hybrid wing body (HWB) aircraft to meet NASA’s aggressive technology goals. This paper presents the conceptual cycle and mechanical designs of the two engine concepts, podded and embedded systems, which were proposed for a HWB cargo freighter. They are expected to offer significant benefits in noise reductions without compromising the fuel burn.

Abstract:
There is a rapid growth of electricity consumption in the world. This problem needs enough resources for capital investment for construction of new power plants and/or making all efforts to increase the thermal efficiency of existing power generation cycles. Therefore this situation has lead power generation industries to repower and modify the existing steam power plants which are constructed in the recent three or four decades. In this paper an important method for repowering of old steam power plants which uses a gas turbine is analyzed. Hot Wind Box (HWB) repowering method was technically and economically evaluated to repower the Besat steam power plant. This power plant was constructed and exploited in 1967 in Tehran. The optimum design parameters such as gas turbine power output, compressor and turbine isentropic efficiency, pressure ratio, and the ratio of turbine inlet temperature to compressor inlet temperature were found by defining an objective function the total cost per unit of repowered plant power output and using numerical search optimization technique for its minimizing. The objective function, the total cost, included initial or capital investment, operation and maintenance costs during plant life cycle. The numerical values of optimum design parameters and the results of the sensitivity analysis are reported.

Abstract:
Boundary layer ingesting inlets for hybrid wing body aircraft have been investigated at some depth in recent years due to the theoretical potential for fuel burn savings. Such savings derive from the ingestion of a portion of the low momentum wake into the propulsor to reenergize the flow, thus yielding total power savings and reducing required block fuel burn. A potential concern for BLI is that traditional concepts such as “thrust” and “drag” become less clearly defined due to the interaction between the vehicle aerodynamics and the propulsive thrust achieved. One such interaction for the HWB concept is the lateral location of the inlet on the upper surface which determines the effective Reynolds number at the point of ingestion. This is an important factor in determining the amount of power savings achieved by the system, since the boundary layer, displacement, and momentum thicknesses are functions of the local chord length and airfoil shape which are all functions of the lateral location of the engine. This poses a design challenge for engine layouts with more than two engines as at least one or more of the total engines will be operating at a different set of changing inlet conditions throughout the flight envelope. As a result, the engine operating point and propulsive performance will be different between outboard and inboard engines at flight conditions with appreciable boundary layer influence including key flight conditions for engine design: takeoff, top of climb, and cruise. The optimal engine design strategy in terms of performance to address this issue is to design separate engines with similar thrust performance. This strategy has significant challenges such as requiring the manufacturing and certification of two different engines for one vehicle. A more practical strategy is to design a single engine that performs adequately at the different inlet conditions but may not achieve the full benefits of BLI. This paper presents a technique for cycle analysis which can account for the disparity between inlet conditions. This technique was used for two principal purposes: first to determine the effect of the inlet disparity on the performance of the system; second, to analyze the various design strategies that might mitigate the impact of this effect. It is shown that a single engine can be sized when considering both inboard and outboard engines simultaneously. Additionally, it is shown that there is a benefit to ingesting larger mass flows in the inboard engine for the case with large disparity between the engine inlets.
