The impacts of forest management on habitat characteristics, species richness, and population dynamics of small mammals remain ambiguous. We studied the response of small-mammal populations, including snowshoe hares, to clear-cutting with protection of advanced regeneration and soils (CPRS) and precommercial thinning (PCT). We compared stands recently treated by CPRS or PCT with established stands dominated by deciduous or coniferous trees in two large blocks of mixed forests. We measured habitat components and abundance of small mammals in the four stand types. Trees (DBH ≥ 9 cm) became very rare in CPRS stands and remained at low density in PCT stands, which stimulated the growth of herbs and seedlings, resulting in increased lateral cover. Tree harvest also generated coarse woody debris in CPRS stands, which did not persist in PCT stands. Small mammals responded to these disturbances in a species-specific manner but, overall, relative abundance and species richness of small mammals were lower in PCT stands than in CPRS and closed stands. Our results suggest that forest managers should exclude some stands from PCT following CPRS or natural perturbations, to maintain ecosystem diversity at the landscape level.

The ownership of common property resources was always in conflict within community and community vs government. Definition about common property resources are advanced on the mainly upon their priority, visibility, accessibility and understanding. Further, its broad classification includes harvesting, extraction and natural production. The nature of dependency among Common Property Resources(CPRs) and Private Property Resources(PPRs) follows higher exploitation with initial compared to the later. The present study is carried out in Tribal dominated district of Odisha, India i.e. Mayurbhanj through stratified and multi-stage random sampling to answer how important are CPRs for tribal across Mayurbhanj and their dependency upon types of resources with utilisation and limitation. The assessment of LDI (Livelihood Dependency Index) reveals higher dependency of sample respondents of Mayurbhanj upon CPRs for livelihood continuation even after having an average membership in Self Help Group programme from last seven years. There exist massive need of making diversified occupation adjustment especially for population residing nearby forest like engagement in transport of forest items, maintenance, local auction, daily wage based leaf collection and storage for government auction, maintenance and engaging women members in manufacturing of CPR based items.

Abstract Resource management characterized by Common Pool Resources (CPRs) requires collective action for its sustainable management. CPRs with “rivalry” and “non-excludable” features face overexploitation problems because unlike the nature of pure public goods, the use of CPRs by one user will reduce the chances of other users taking advantage of it. This study aims to analyze the most appropriate local institutions and tenure arrangements for sustainable mangrove management in Eastern coast area of South Sulawesi, Indonesia. Data and information were collected through in-depth interviews involving key informants selected by using snow-ball method and continued by Focus Group Discussion. Design principles for sustainable management of common pool resources of Ostrom has been used in this study as an analytical framework which illustrate the structure of rules established and imposed by the local CPR’s institutions. The findings show that collective action in sustainable mangrove management can be achieved through accepted rules and agreements that are participatory formulated. The agreed norms and rules have enacted as a benchmark for collective action in maintaining mangrove and to enforce sanctions for violators. The success of the community in sustainable mangrove resources management is mainly supported by the existence of several prerequisites that facilitate collective action. It is necessary to strengthen regulations both at the local and higher level through socialization to the community along with the development of incentive and disincentives system.

Sustainable forest management involves, among other things, maintaining diversity of ecosystems and preserving their natural processes. The main objective of this paper is to consider the validity of current harvesting techniques applied to the mixed forest of Québec. The old-growth mixed forest naturally regenerates by gap dynamics. However, the harvesting technique most commonly used in the mixed forest is clearcutting, with the result that succession must start over from the beginning. A general forest succession model applicable after such large disturbances is proposed. The most positive estimate indicates that the mixed forest will not be re-established earlier than 250 years after clearcutting. To ensure sustainable development in the mixed forest, harvesting techniques should imitate natural regeneration processes. Key words: balsam fir-yellow birch stands, CPRS, gap dynamics, succession model, sustainability, sustainable development

Community-based conservation is advocated as an idea that long-term conservation success requires engaging with, providing benefits for, and establishing institutions representing local communities. However, community-based conservation’s efficacy and impact in sustainable resource management varies depending on national natural resource policies and implications for local institutional arrangements. This paper analyses the significance of natural resource management policies and institutional design on the management of common pool resources (CPRs), by comparing Namibian conservancies and community forests. To meet this aim, we reviewed key national policies pertinent to natural resource governance and conducted 28 semi-structured interviews between 2012 and 2013. Key informants included conservancy and community forest staff and committee members, village headmen, NGO coordinators, regional foresters, wildlife officials (wardens), and senior government officials in the Ministry of Environment and Tourism and the Ministry of Agriculture, Water and Forestry. We explored the following questions: how do national natural resource management policies affect the operations of local common pool resource institutions? and how do external factors affect local institutions and community participation in CPRs decision-making? Our results show that a diversity of national policies significantly influenced local institutional arrangements. Formation of conservancies and community forests by communities is not only directly linked with state policies designed to increase wildlife numbers and promote forest growth or improve condition, but also formulated primarily for benefits from and control over natural resources. The often-assumed direct relationship between national policies and local institutional arrangements does not always hold in practice, resulting in institutional mismatch. We aim to advance theoretical and applied discourse on common pool resource governance in social-ecological systems, with implications for sustainable land management policies in Namibia and other landscapes across sub-Saharan Africa.

Out of the 104 islands of Indian Sundarbans, 54 are inhabited. These islands have mud embankments which protect them from intrusion of river and sea water and have made human settlement possible in these islands. Once the embankments were protected from tidal and storm surges by a layer of mangrove forests. But now the mangrove cover has vanished and consequently the embankments are frequently eroded or develop breaches being directly exposed to tidal and storm surges. One way to protect these mud embankments is to recreate mangrove plantations along the toe-line on the outer side of the embankments. This article uses a framed lab-in-field experiment to measure inclination towards community participation in regenerating common pool resources (CPRs), specifically regeneration of mangrove forest on the outer side of the embankments. The 320 subjects who participated in the experiment were villagers from different islands in the Indian Sundarbans. The experiment is a hybrid of the simple Public Goods Game with Voluntary Contributions Mechanism (VCM) and the Trust Game. The first is used to measure inclination towards contributing resources and effort for generation of CPRs and the second is to see if the participants trust others not to extract from the regenerated CPR and if such trust is reciprocated. The results show that voluntary contributions, contrary to theoretical prediction of free riding, are significantly high, though less than when there is no extraction. Trust levels are also quite high and a third of such trust is reciprocated. JEL Codes: C92, H40, Q23

This study aims to identify the causes of illegal access for the community in carrying out mangrove utilization activities as raw material for charcoal in Batu Ampar District, Kubu Raya, West Kalimantan. This research was conducted in 3 villages in Batu Ampar Subdistrict, namely Batu Ampar Village, Nipah Panjang Village and Teluk Nibung Village. Data collection was done through field observations, in-depth interviews, documentation studies and literature studies. Data analysis used descriptive analysis method with the Theory of Access approach according to Ribot and Peluso (2003). The results showed that the causes of illegal access in the use of mangroves as a raw material for charcoal by the community in Batu Ampar Subdistrict were the characteristics of protected forest resources as Common Pool Resources (CPRs) and high exclusion costs and the obmission of local government. The communities get the power of access to protected forests in Batu Ampar mainly through access to capital provided by investors (cukong), both collectors and buyers.

Some regenerating stands of the boreal forest exhibit low juvenile growth after major disturbances, which compromises sustainable forest management objectives. In black spruce – feather moss stands of eastern Canada subject to paludification, careful logging methods could decrease stand productivity with time by preventing a beneficial reduction in organic soil thickness. The aim of this project was to confirm decreases in juvenile growth between stands originating from careful logging and the former stands originating from old fires on the same sites. Stem analyses showed that stands originating from CPRS had significantly better juvenile height growth than the former stands but significantly lower growth than stands originating from recent fire in the study region. If organic matter thickness apparently played a role in the growth differences observed between fire and harvesting, it was not the only factor determining stand productivity. According to our results, cohort status, climatic regime, and quality of the residual organic matter are other factors that seem to drive productivity. Our results show that postharvest management approaches (e.g., site preparation) should be used to increase yields after harvest for the sites to express their full growth potential.

Forest resources will suffer damage and sustainability if they are used excessively. The characteristics of common-pool resources (CPRs) are forms of natural resources that involve many people so that they are vulnerable to damage due to the inability of the owner or manager to restrict other parties from taking part in utilizing them (non-excludable/non-trivial), and the use made by one party will reduce the benefits for the other party (subtractable). The actors in the network have made a good contribution in solving the challenges of the tasks and functions of the FMU in implementing community empowerment policies so that FMU development programs can be accepted by all stakeholders interests, especially local leaders, business people, relevant technical agencies, community leaders, non-governmental organizations, and village communities as beneficiaries. This research is qualitative-verificative with a case study approach that aims to understand the empirical phenomenon of the implementation process of forest community-based forest management policies. Stakeholder data was collected in implementing community empowerment policies in the Yogyakarta Model KPHP stakeholders. This qualitative analysis is historical-comparative, based on historical chronology with inductive and generative methods. The recommended empirical model analyzes the role of leadership in the FMU and the influence of the symbolic figure (Ngarso Dalem) in forming a network of actors and successfully implementing community empowerment policies in the Yogyakarta Model KPHP. Stakeholders must collaborate to solve the challenges of working on FMUs so that FMU development programs can be accepted by all stakeholders, especially local leaders, business people, relevant technical agencies, community leaders, Non-Governmental Organizations, and the community itself as beneficiaries.

Abstract The aim of this study was to investigate the species composition of prey caught in the forest, savanna and emerging habitats in which African Crowned Eagles Stephanoaetus coronatus breed in KwaZulu-Natal province, South Africa. At the 17 nest sites, the remains of 195 prey individuals were collected. The five dominant prey species caught were Rock Hyrax Procavia capensis, Vervet Monkey Chlorocebus pygerythrus, Blue Duiker Philantomba monticola, Greater Canerat Thryonomys swinderianus and Bushbuck Tragelaphus scriptus. All of these species respond positively to urban expansion. Only eagles that nested inside protected areas were recorded preying on domestic animals. In terms of biomass, Bushbuck was one of the dominant taxa, and the remains of an estimated 28.8 kg Bushbuck ram was found under a nest. The surprisingly high proportion of Rock Hyraxes and low proportion of Vervet Monkeys caught in emerging habitat may indicate that African Crowned Eagles nesting in this habitat are adapting to a more specialised feeding strategy compared with those nesting in habitats that are more natural. Future studies should investigate how and why prey proliferates in emerging habitats and examine the association between land uses and the diet of African Crowned Eagles.

Abstract In 2008 the highest number of attacks recorded against ships in the world was reported to have taken place off the coast of Africa. These attacks were carried out at greater distances from land, along the east coast of Africa, than ever before. In this article the extent of piracy and armed robbery against ships in the African context and underlying causes of piracy and armed robbery against ships off the coast of East Africa will be presented. The objective is to analyse incidents and the land and sea based causes in East Africa to account for the shift in strategy from attacking ships in territorial waters to attacking ships on the high seas. A secondary aim is to determine, in view of the shifting background to the attacks, the responsibilities of navies and other role players in the process of countering such attacks. The article suggests that states need to review national legislation related to maritime security and that all state role players in the maritime domain need to cooperate more efficiently.

Anaesthetists have a central role in cardiopulmonary resuscitation (CPR). The incidence of treated out-of-hospital cardiopulmonary arrest is 40 per 100 000 population and is associated with a survival rate to hospital discharge of 8–10%. The incidence of in-hospital cardiac arrest (IHCA) is 1–5 per 1000 admissions and is associated with a survival rate to hospital discharge of 13–17%. The most effective strategy for reducing mortality from IHCA is to prevent it occurring by detecting and treating those at risk or to identify in advance those with no chance of survival and to make a decision not to attempt resuscitation. The European Resuscitation Council and the Resuscitation Council (UK) publish guidelines for CPR every 5 years and the evidence supporting these is described in the international consensus on CPR science. The advanced life support algorithm forms the core of the guidelines but the precise interventions depend on the circumstances of the cardiac arrest and the skills of the healthcare providers. High-quality CPR with minimal interruptions will optimize survival rates. Shockable rhythms are treated with defibrillation while minimizing the pause in chest compressions. Although adrenaline (epinephrine) is used in most cardiac arrests, no studies have shown that it improves long-term outcome. The post-cardiac arrest syndrome is common and requires multiple organ support in an intensive care unit. Therapy in this phase is aimed at improving neurological (e.g. targeted temperature management) and myocardial (e.g. percutaneous coronary intervention) outcomes. Based on standard outcome measurements (e.g. cerebral performance category), 75–80% of survivors will have a ‘good’ neurological outcome, but many of these will have subtle neurocognitive deficits.

AbstractIn the concluding chapter, we synthesize the results and discuss how changing land-use regimes among Sami in interior northwest Fennoscandia interrelated with the development of property rights between 1550 and 1780. During this period, a new tenure system, reindeer pastoralism, developed. For households that had amassed large reindeer herds, it became crucial to access both large pastures in the mountains and in the boreal forest to have enough grazing. This led to the establishment of common-property regimes in both the mountains and the boreal forest, where grazing became a CPR. The emergence of this kind of common-property regime is best described as a bottom-up process as it assumes that local users design and implement institutions for common use that all or most users adhere to.

Cyber Physical System (CPS) is one of the key technologies of industry 4.0. CPS is an integrated system that combines computing, sensors and actuators. CPS is controlled by computer-based algorithms that integrates people and internet. However, the performance of CPS is limited by its computational complexity. How to implement CPS with less computational complexity in a real time performance remains an important issue. Therefore, the study attempts to establish a CPS based on machine learning to reduce its complexity and improve applicability. This study applies a Fault Detection and Classification system (FDC) with machine learning method in the virtual subsystem of CPS. This study consists of two steps. Based on the data collected from sensors of CPS, Random Forest (RF) is used to figure out key factors that reduces the data dimension for less computational complexity. The process engineers will know which factors are causing the machine fails. The second step is to establish a time series model which bases on Long Short-Term Memory (LSTM) network to achieve real time monitoring of the machine. Before the machine fails, FDC will alarm that allow the engineer to adjust parameters of machines to avoid machine fails. The study in order to achieve the goals of predicting machines fails, figuring out key factors, predicting maintenance and increasing the productivity.

Fire Dynamic Simulator (FDS), a fire simulation program, applies Message Passing Interface (MPI) and Open Multi Processing (OpenMP) libraries for large-scale simulation. FDS can be executed by dividing simulation problems in a computing cluster using MPI. The main point is to divide the entire domain to be interpreted into several sub-domains and allow each sub-domain to be calculated by an individual computer with an individual processor. When performing parallel computation, FDS first decomposes each sub-domain, then supports two-step parallelization in which multi-threading is applied within each sub-domain, and uses the OpenMP library to implement multi-threading. In this study, OpenACC, a parallelization technique capable of using heterogeneous hardware architectures, was partially applied to FDS. As an application problem, the calculation performance is evaluated through CSIRO Grassland Fires, a verification case of FDS. The hardware for evaluation was a personal computer consisting of dual Xeon 2678-V3 and GeForce GTX 1070. The FDS source code applies OpenACC using PGI Fortran as a compiler in Linux environments. In calculation performance, calculations using CPU and GPU together show 1.89 times faster performance than calculations using a single CPU. In case of using 1 GPU and 16 CPUs (MPP + OpenACC), the analysis result is 21 times faster. In this regard, analysis of grassland fire of WFDS was performed.

This chapter presents the modeling results and their interpretation. First, the synthesis of success factors from existing success factor syntheses is developed and theoretically motivated. Then, the descriptive statistics and correlations between success factors are described analogously for each data set (CPR, NIIS, IFRI, and an overall model from all data sets). Finally, for each modelling methodology (multivariate regressions, random forests, and neural network), the model qualities are presented. In addition, the individual factors are described according to their importance for ecological success. Each presentation of results is followed by a discussion. The chapter is concluded with robustness and sensitivity analyses.

Desulfurization of fuel oils is an essential process employed in petroleum refineries to reduce the sulfur content to levels mandated for environmental protection. Hydrodesulfurization (HDS), which is currently being employed, is limited in treating refractory organosulfur compounds and only reduces the sulfur content in fuels to a range of 200-500 ppmS. In this chapter, several scientific and technological advances reported in the literature for the desulfurization of fuels are reviewed and discussed. Amongst these techniques, oxidative desulfurization (ODS) and adsorptive desulfurization (ADS) are proposed as additional steps to complement HDS in meeting the mandated ultra-low sulfur levels (10 ppmS). In the ODS technique, refractory organosulfur compounds are oxidized to organosulfones, followed by solvent extraction or adsorption of the organosulfones. The chemistry involved in the development and fabrication of sulfur/sulfone responsive adsorbents is also discussed. The use of molecular imprinted polymers (MIPs) and coordination polymers (CPs) for the selective adsorption of organosulfone compounds (in ODS) and/or organosulfur (in ADS) offers various properties such as imprinting effect, hydrogen bonding, π-π interactions, van der Waals forces, π-complexation, and electrostatic interactions. CPs, in particular metal organic frameworks (MOFs), have been reported to possess suitable features to overcome most of these challenges associated with adsorptive ultra-deep desulfurization when design strategies to achieve good selectivity are strictly followed. Matching the sizes of the cavities to the critical dimensions of the sulfur containing compounds (SCCs), using suitable metal centres which allow for coordinative interaction with the SCCs and using linkers with suitable functionality as to enhance specific interaction (dispersion forces) with the SCCs were considered to be pivotal features to prioritize. The prospects for the use of MIPs and CPs for future industrial applications in desulfurization are envisaged.

Endometrial thickness in assisted reproductive techniques is one of the essential factors in the success of pregnancy. Despite extensive studies on endometrial thickness prediction, research is still needed. We aimed to analyze the impact of endometrial thickness on the ongoing pregnancy rate in couples with unexplained infertility. A total of 729 couples with unexplained infertility were included in this study. A random forest model (RFM) and logistic regression (LRM) were used to predict pregnancy. Evaluation of the performance of RFM and LRM was based on classification criteria and ROC curve, Odd Ratio for ongoing Pregnancy by EMT categorized. The results showed that RFM outperformed the LRM in IVF/ICSI and IUI treatments, obtaining the highest accuracy. We obtained a 7.7mm cut-off point for IUI and 9.99 mm for IVF/ICSI treatment. The results showed machine learning is a valuable tool in predicting ongoing pregnancy and is trustable via multicenter data for two treatments. In addition, Endometrial thickness was not statistically significantly different from CPR and FHR in both treatments.

This paper presents a novel class of 3-DOF translational compliant parallel manipulators (CPMs) based on flexure motion. The analytic mathematic modeling of CPMs is first developed. The analysis of CPMs is then implemented. It is shown that the proposed CPMs have many characteristics such as large range of motion, negligible cross-axis coupling, actuator complete isolation, and no loss motion and no rotational yaw. The inverse relationships of force-displacement of the 3-DOF CPM are further derived to calculate the input forces required for generating a specified path. In addition, the 3-DOF CPM can also be turned into a 2-DOF CPM. This work lays the foundation for the development of new spatial CPMs based on flexure motions for applications such as ultra precision manipulation.

Boxing or martial arts are games where players chests are subject to lateral impact, the impact loads travel through skin, ribs, mediastinum (i.e. a thoracic compartment) and then through the skeleton to the rest of the body. When thorax is subject to lateral force exceeding the elastic limit of thoracic compartment, players often go in shock demanding prompt resuscitation. This paper investigates the thorax response of boxer being subject to lateral impact followed by Cardiopulmonary resuscitation (CPR). Due to complexity of thorax structure and materials, three dimensional finite element model in ANSYS was created to perform the computational biomechanical analysis of two-stage loading (i.e. lateral impact load and CPR forces). Model input parameters such as material, loading and boundary conditions have been defined. Post processing values such as deformations and stresses have been presented.

The purpose of this paper is, to provide the non-linear biodynamic response of thorax through the analytical and numerical simulation methods. Adult thorax data considering sagittal and coronal stiffness in addition to soft and hard tissue material properties will undergo CPR impulsive loading. The numerical simulation is conducted using finite element analysis (FEA) software for modeling biomechanical correct Thorax model to CPR transient loading. AMTI force plate was utilized to record the CPR forces, it accounts for realistic load evaluation during CPR procedure. A dynamic model for numerical simulation includes resonance frequency, damping coefficient, stiffness constant and extinction time for a different kind of physique. The model deflections and forces were analyzed. The maximum deflection obtained from mathematical modelling and ANSYS is found closely related. The result strongly depends on the modeling of the thorax which is used in the numerical simulation. This indicates the necessity of the correlation of the results with the experimental data if available.

Multivariate time series forecasting is an important task in state forecasting for cyber-physical systems (CPS). State forecasting in CPS is imperative for optimal planning of system energy utility and understanding normal operational characteristics of the system thus enabling anomaly detection. Forecasting models can also be used to identify sub-optimal or worn out components and are thereby useful for overall system monitoring. Most existing work only performs single step forecasting but in CPS it is imperative to forecast the next sequence of system states (i.e curve forecasting). In this paper, we propose DyAt (Dynamic Attention) networks, a novel deep learning sequence to sequence (Seq2Seq) model with a novel hierarchical attention mechanism for long-term time series state forecasting. We evaluate our method on several CPS state forecasting and electric load forecasting tasks and find that our proposed DyAt models yield a performance improvement of at least 13.69% for the CPS state forecasting task and a performance improvement of at least 18.83% for the electric load forecasting task over other state-of-the-art forecasting baselines. We perform rigorous experimentation with several variants of the DyAt model and demonstrate that the DyAt models indeed learn better representations over the entire course of the long term forecast as compared to their counterparts with or without traditional attention mechanisms. All data and source code has been made available online.

CFD simulations of pump suction piping coupled to a double suction volute pump were performed with oil at a viscosity of ~90 cSt. Two variants of the suction piping were modeled in order to investigate their effect on the pump performance. Measurement data obtained during PRCI project CPR-15A were used to validate the CFD setup. The CFD results were mostly in line with the measurements, in particular performance and pressure tap values in the suction piping. The pump rotor forces predicted by CFD however showed significant differences to the measured values. The CFD setup presented in this report provides a basis framework for further CFD investigations. This work will benefit the liquids pipeline station designers and operators and also CFD analysts by providing CFD comparisons to benchmark measurements.

Annotation:
In 2008, Pipeline Research Council International (PRCI) took the initiative to identify the main causes of reportable incidents in compressor and pump stations. Data was gathered from several sources including the United States� Department of Transportation Pipeline and Hazardous Materials Safety Administration, Canada�s National Energy Board, and PRCI member companies. More than 1600 incidents were reviewed over an 18 year period (1990 to 2008). The incidents were evaluated based on their frequency of occurrence and the consequences of the incidents (injury, ignition, environmental impact, etc�). In pump stations, pump seals, valves out of sequence due to operator error, and gasket and bolting were identified as the highest impact incidents types. In compressor stations, the three highest impact incident types were found to be pipe components, natural forces (hurricanes and lightning strikes), and gaskets and bolting. During the 2008 project, research roadmaps were developed based on the results of the incident data review. In the process of defining the research projects, a brief review into the available technology for the incidents types was conducted. It was quickly found that a more detailed state-of-the-art review was needed to accurately identify the research required for several of the incident areas. Therefore, a state-of-the-art review of the three highest impact incidents in pump and compressor stations was proposed. The work documented in this paper is the state-of-the-art review of these incidents. In the PRCI CPS 9-1 (2008) project, it was found that more information was needed on several of the incidents in order to fully define the root cause. Therefore, the first task of the PRCI CPS 9-1 (2009) effort was to attempt to gather more information on the top three impact incident types. Thirty-two pipeline companies were contacted and additional information was provided for approximately 25% of the incidents. From the review of this additional and past data, several focus areas were identified for the state-of-the-art reviews. The state-of-the-art studies included a survey of the current technology, identification of common failure mechanisms, and review of strategies to reduce incident occurrences. These studies are reviewed in detail in the appendices of this document. From the state-of-the-art studies and the incident review, technology gaps were identified. Technology gaps are areas where new innovative technologies or applications are required to address current inspection/maintenance strategies for a particular piece of equipment or task. Technology gaps were only identified for pump seals. These gaps included the inability for pump seals to survive process upset conditions, inability to correctly identify and model expected loads and operating conditions for pump seal selection, and lack of installed seal inspection or life prediction methods except through leakage detection. All other incident types (valves out of sequence due to operator error, gaskets and bolting, pipe components, and natural forces) have adequate technology to address the incident occurrences. In the majority of the incidents, even though the technologies exist, it may not be used or applied correctly. Several recommendations were made for future work. These included work that a company may consider conducting internally to reduce the occurrence of incidents and future research. The recommendations for future work for operators and research for industry are summarized in a list below. Research items included on the research roadmaps are indicated with an asterisk.
