Semantic Plurality
Authors: Gardelle Laure
Published: October 2019

This monograph proposes a comparative approach to all the ways of denoting ‘more than one’ entity, from collective and aggregate nouns (with the first-ever typology), to count plurals, partly substantivised adjectives and conjoined NPs. This semantic feature approach to plurality, which cuts across number, the count/non-count distinction, and lexical/NP levels, reveals a very consistent Scale of Unit Integration, which establishes clear-cut boundaries for collective nouns, and accommodates cases such as three elephant, cattle or a chain of islands. The study also offers a refined understanding of aggregate nouns (a category nearly as large as that of collective nouns) and quantification in pseudo-partitives, develops Guillaume’s notion of ‘internal plurality’, and proposes the innovative concept of ‘hyperonyms of plural classes’ (e.g. furniture). The Animacy Hierarchy is also found to be influential, beyond hybrid agreement. The book aims to be accessible to scholars of any theoretical background interested in these topics.

Serving people
Authors: Wu Mingdan , Del Percio Alfonso
Published: October 2019

In this article, we explore the imbrication of service work with consumer markets and larger structures of inequality, including gender and class divides as well as social and economic differences. In line with current sociolinguistic scholarship on language and work, we are interested in the activity of serving people – both in the sense of being or becoming people who serve as well as in the practice of providing services to people. To do so, we offer an ethnographic account of the regime of labor surveillance as well as the daily work practices of female workers at a Starbucks coffeehouse in London, UK. We wonder about how employers organize the bodies of workers into signs, codes and messages that appeal to customers’ class expectations of this type of consumption. By documenting the regimentation and surveillance of labor at Starbucks, we inquire into the prescribed rules that guide ‘proper’ presentations of physicality; further, we ask questions about the mechanism through which the body at Starbucks is made to express its positioning within a structure of labor and its relationality to others, especially customers.
Exploring the changing forms of caste-violence: A study of Bhumihars in Bihar, India
Authors: Nandan Aniket , Santhosh R.
Published: October 2019

In this paper, we reflect on the caste-violence perpetrated on lower castes by Bhumihars, one of the dominant castes in Bihar, India, as it indicates their complex relationship with important socio-economic and political issues such as land relations, identity assertion and socio-economic differentiation, among others. We also pay attention to ideological and moral constructs embedded in the narratives about Bhumihars, which provides legitimacy to their violence. Several narratives and personal interviews have been incorporated in our analysis along with a broader mapping of Bhumihars’ historical engagement with violence as a form of caste assertion and its changing character in the contemporary era marked by ‘backward-caste’ mobilisation and the rise of Hindu right-wing politics in Bihar. Our critical study traces these historical trajectories and points to a decisive shift from Bhumihars’ engagement with direct violence towards a more subtle and symbolic form of violence, often masquerading as their articulation and expression of caste identity.

Published: October 2019

A knowledge-based understanding of the plasma-surface-interaction with the aim to precisely control (reactive) sputtering processes for the deposition of thin films with tailored and reproducible properties is highly desired for industrial applications. In order to understand the effect of plasma parameter variations on the film properties, a single plasma parameter needs to be varied, while all other process and plasma parameters should remain constant. In this work, we use the Electrical Asymmetry Effect in a multi-frequency capacitively coupled plasma to control the ion energy at the substrate without affecting the ion-to-growth flux ratio by adjusting the relative phase between two consecutive driving harmonics and their voltage amplitudes. Measurements of the ion energy distribution function and ion flux at the substrate by a retarding field energy analyzer combined with the determined deposition rate R
d for a reactive Ar/N2 (8:1) plasma at 0.5 Pa show a possible variation of the mean ion energy at the substrate E
m
ig within a range of 38 and 81 eV that allows the modification of the film characteristics at the grounded electrode, when changing the relative phase shift θ between the applied voltage frequencies, while the ion-to-growth flux ratio Γig/Γgr can be kept constant. AlN thin films are deposited and exhibit an increase in compressive film stress from −5.8 to −8.4 GPa as well as an increase in elastic modulus from 175 to 224 GPa as a function of the mean ion energy. Moreover, a transition from the preferential orientation (002) at low ion energies to the (100), (101) and (110) orientations at higher ion energies is observed. In this way, the effects of the ion energy on the growing film are identified, while other process relevant parameters remain unchanged.
Experimental realization of a hybrid trapped field magnet lens using a GdBaCuO magnetic lens and MgB2 bulk cylinder
Authors: Namba Sora , Fujishiro Hiroyuki , Naito Tomoyuki , Ainslie Mark D , Takahashi Keita
Published: October 2019

A hybrid trapped field magnet lens (HTFML) is a promising device that is able to concentrate a magnetic field higher than the applied field continuously, even after removing an external field, which was conceptually proposed by the authors in 2018. This paper presents, for the first time, the experimental realization of the HTFML using a GdBaCuO magnetic lens and MgB2 trapped field magnet cylinder. A maximum concentrated magnetic field of B
c = 3.55 T was achieved at the central bore of the HTFML after removing an applied field of B
app = 2.0 T at T = 20 K. For higher B
app, the B
c value was not enhanced because of a weakened lens effect due to magnetic flux penetration into the bulk GdBaCuO material comprising the lens. The enhancement of the trapped field using such an HTFML for the present experimental setup is discussed in detail.
Local order parameters for symmetry fractionalization
Authors: Garre-Rubio José , Iblisdir Sofyan
Published: October 2019

We propose a family of order parameters to detect the symmetry fractionalization class of anyons in 2D topological phases. This fractionalization class accounts for the projective, as opposed to linear, representations of the symmetry group on the anyons. We focus on quantum double models on a lattice enriched with an internal symmetry in the framework of G-isometric projected entangled pair states. Unlike previous schemes based on reductions to effective 1D systems (dimensional compactification), the order parameters presented here can be probed on genuinely two-dimensional geometries, and are local: they rely on operations on few neighbouring particles in the bulk. The power of these order parameters is illustrated with several combinations of topological content and symmetry. We demonstrate that a strictly finer phase distinction than that provided by dimensional compactification can be obtained. As particular examples, the resolution power of these order parameters is illustrated for a case with non-abelian topological order, and for another with symmetries that involves permutation of anyons.

Published: October 2019

We conducted in-situ high-pressure synchrotron x-ray diffraction (XRD) and electrical transport measurements on Dirac-like semimetal PdSn4 in diamond anvil cells with quasi-hydrostatic pressure condition up to 44.5 GPa–52.0 GPa. The XRD data show that the ambient orthorhombic phase (Ccca) is stable with pressures to 44.5 GPa, and the lattice parameters and unit-cell volume decrease monotonously upon compression. The temperature dependence of the resistance exhibits a metallic conduction and follows a Fermi-liquid behavior below 50 K, both of which keep unchanged upon compression to 52.0 GPa. The magnetoresistance curve at 5 K maintains a linear feature in a magnetic field range of 2.5 T–7 T with increasing pressure to 20.0 GPa. Our results may provide pressure-transport constraints on the robustness of the Dirac fermions.

The temperature dependences of upper critical field (H
c2) for a series of iron-deficient Fe1−x
Se single crystals are obtained from the measurements of in-plane resistivity in magnetic fields up to 9 T and perpendicular to the ab plane. For the samples with lower superconducting transition temperature T
c (<7.2 K), the temperature dependence of H
c2 is appropriately described by an effective two-band model. For the samples with higher T
c (≳ 7.2 K), the temperature dependence can also be fitted by a single-band Werthamer–Helfand–Hohenberg formula, besides the two-band model. Such a T
c-dependent change in H
c2(T) behavior is discussed in connection with recent related experimental results, showing an inherent link between the changes of intrinsic superconducting and normal state properties in the FeSe system.

Published: October 2019

Objective. We have demonstrated previously that microstimulation in the dorsal root ganglia (DRG) can selectively evoke activity in primary afferent neurons in anesthetized cats. This study describes the results of experiments focused on characterizing the postural effects of DRG microstimulation in awake cats during quiet standing. Approach. To understand the parameters of stimulation that can affect these postural shifts, we measured changes in ground reaction forces (GRF) while varying stimulation location and amplitude. Four animals were chronically implanted at the L6 and L7 DRG with penetrating multichannel microelectrode arrays. During each week of testing, we identified electrode channels that recruited primary afferent neurons with fast (80–120 m s−1) and medium (30–75 m s−1) conduction velocities, and selected one channel to deliver current-controlled biphasic stimulation trains during quiet standing. Main results. Postural responses were identified by changes in GRFs and were characterized based on their magnitude and latency. During DRG microstimulation, animals did not exhibit obvious signs of distress or discomfort, which could be indicative of pain or aversion to a noxious sensation. Across 56 total weeks, 13 electrode channels evoked behavioral responses, as detected by a significant change in GRF. Stimulation amplitude modulated the magnitude of the GRF responses for these 13 channels (p   <  0.001). It was not possible to predict whether or not an electrode would drive a behavioral response based on information including conduction velocity, recruitment threshold, or the DRG in which it resided. Significance. The distinct and repeatable effects on the postural response to low amplitude (<40 µA) DRG microstimulation support that this technique may be an effective way to restore somatosensory feedback after neurological injuries such as amputation.

Published: October 2019

This paper aimed to examine some issues of kindergarten students’ learning about Physics. Students’ making sense of speed and velocity will be interpreted. Participants included twenty kindergarten students (4-5 years old) who were studying in Khon Kaen University Kindergarten Demonstration School, Khon Kaen, Thailand. Methodology regarded interpretive paradigm. The goal of kindergarten schools includes development of motor, emotion and mind, social, and cognitive skills. On the way of development of these skills, they may also make sense of science concepts. The students’ making sense of speed and velocity will be interpreted during students’ on activities for development of gross motor skills. Tools of interpretation included participant observation and informal interview when students were participating on the activities for development of gross motor skills as playing with the ball. The activity was carried out for two months. Students’ activities of playing with the ball indicated that some of students made sense of the speed and velocity concept when they showed that they play well on the ball as their perception of the relation of hand, eye, and moving of the ball. It could be mentioned that they not only developed on gross motor skills but also concept of ball moving as speed and velocity. This study may have implications for enhancing kindergarten students to learn science.

Analysis of wake effects on global responses for a floating two-turbine case
Authors: Wise A , Bachynski E E
Published: October 2019

While most existing modeling and analysis of floating wind turbines (FWTs) considers isolated systems, interactions among multiple FWTs arranged in an array have received little attention. In this study, two 10 MW semi-submersible FWTs, separated by 8 rotor diameters (D) in the wind direction, are simulated with an ambient wind speed of 10 m/s and in moderate wave conditions using FAST. Farm to investigate the effects of wakes on global responses. Synthetic inflow is generated using three methods: the Kaimal turbulence model, 1) without and 2) with spatial coherence in the lateral and vertical velocity components, and 3) the Mann turbulence model (where spatial coherence in all three dimensions is inherent to the model). The first method results in negligible wake meandering, a relatively uniform wake deficit, while the second and third methods result in meandering of the upstream turbine’s lateral wake center at the downstream turbine’s rotor plane of up to approximately 1D and 1.5D, respectively. The slow meandering behavior of the upstream turbine’s wake resulted in increased low-frequency platform motions for the downstream turbine. Yaw motions were especially susceptible to wake meandering as the standard deviation of the downstream turbine’s yaw motion increased by 28.0 % for the second method and 11.3 % for the third method. Increased low-frequency response in structural loading was also observed. Wake effects led to between 2 % and 30 % greater fatigue damage at the top of the tower for all three methods and at the base of the tower for the second method. However, other results were found to be sensitive to the blade-passing frequency.
Experimental modal analysis of aeroelastic tailored rotor blades in different boundary conditions
Authors: Gundlach J , Govers Y
Published: October 2019

Bend-twist coupled blades are intended to reduce the loads on the overall wind turbine by passively adapting to current wind conditions. The coupling results from complex-design shapes and structures using advanced finite element models utilising shell and volume elements. These models are however prone to mispredict the structural dynamic behaviour of the rotor blades. In particular, normal modes with both bending and torsion contributions, as well as local vibrations of the blade shells include computational uncertainties. Therefore, in order to update flawed model parameter assumptions, a modal characterisation of blade prototypes including mode shapes is essential. In the present study results of a modal test campaign involving four identical rotor blades of 20 m length with geometric bend-twist coupling are reported. Design, realisation, and post-processing of the experiments have been carried out under careful consideration of a pre-existing FE shell model. Modal data is obtained at two different stages of the manufacturing process and for one blade in two separate boundary conditions, i.e. free-free in elastic suspensions and clamped to a test rig. Due to the high sensor density in both configurations, the identified normal modes do not only include coupled eigenforms but also mode shapes illustrating cross-sectional vibrations; the latter attributed to the deflection of the blade shells. The acquired dataset is found to be well-suited for the validation of the numerical model and represents a reliable basis for updating.
Towards a high-resolution offshore wind Atlas - The Portuguese Case
Authors: Couto A , Silva J , Costa P , Santos D , Simões T , Estanqueiro A
Published: October 2019

An accurate offshore wind resource assessment is a key tool for planning marine wind renewable exploitation. To achieve this goal, without resort to an extensive and costly network of anemometric stations or buoys, it becomes necessary to use the so-called atmospheric mesoscale models. This work presents a high spatial resolution (1x1 km) offshore wind resource Atlas for Portugal and the model calibration steps. During the calibration steps, the most adequate: i) atmospheric parameterizations - physics options, ii) initial and boundary conditions (IBC) meteorological datasets, and iii) data assimilation scheme were achieved through sensitivity tests using the common statistical metrics and hourly simulated/observational data. Results show that the most significant improvements are associated with the IBC dataset and the data assimilation scheme used. Thus, the results show that the assimilation procedures coupled with the new ERA-5 reanalysis dataset reduce significantly the errors of the wind speed and direction, especially the normalized mean square error. This reduction, depending on the different calibration setup, can be above 50%. The new Atlas confirms the previous indicators, Portugal presents a high wind power potential, especially for deep offshore regions.
Characteristics of abnormal vertical wind profiles at a coastal site
Authors: Møller Mathias , Domagalski Piotr , Roar Sætran Lars
Published: October 2019

Phenomena such as internal boundary layers and low-level jets can cause short-term wind fluctuations resulting in the vertical wind profile deviating from its expected logarithmic shape. Analysis of several years of data from the 6 measurement heights on the 100m high coastal Skipheia mast reveals that the 10-minute averaged vertical wind profile deviates from the vertical wind profiles predicted by Monin-Obukhov similarity theory in 30 — 40% of the analyzed instances. Deviations were most commonly present in the form of 1 local maxima, and in more rare instances as 2 local maxima or a completely reversed and monotonically decreasing profile. Analyzing the onshore and offshore directional sectors reveals that offshore winds are less reliant on strong thermal gradients for local maxima to be present, and inflections also occur at higher wind speeds in the offshore sector. Inflections are found to be progressively more common at higher elevations regardless of the direction of incoming wind, and as the found inflection elevations are close to common wind turbine hub heights they represent a potential issue in wind engineering.

Published: October 2019

We present, what to our best knowledge, is the most accurate numerical investigation of the wind tunnel tests carried out over a model wind turbine (known as NTNU Blind Test) at the Norwegian University of Sciences and Technology. We show numerical benchmarking of wake measurements against experimental data and similar investigations performed previously by researchers using Computational Fluid Dynamics (CFD) simulations. We have made a full 3D model of the wind turbine and used Sliding Mesh Interface (SMI) approach to handling the rotation of the rotor. The simulations are done with the use of OpenFoam and the k — ω Shear Stress Transport model to resolve turbulence using the Reynolds Average Navier-Strokes (RANS) technique. We present the numerically simulated spatial distribution of the flow field across the wake at zero angles of yaw for horizontal lines downstream of the rotor plane as that was the focus of the NTNU Blind Test presented in [1]
Changes in temperature extremes on the Tibetan Plateau and their attribution
Authors: Yin Hong , Sun Ying , Donat Markus G
Published: October 2019

The Tibetan Plateau (TP) is the largest and highest upland on Earth. Warming on the TP is faster than that in surrounding areas. Evaluating our understanding of the causes behind these changes provides a test of tools used for projections of future climate in the region. In this study, we analyse the observed changes in twelve extreme temperature indices and compare them with model simulations based on the Coupled Model Intercomparison Project Phase 5 (CMIP5). An optimal fingerprinting method is used to perform detection and attribution analyses on the changes in absolute intensity, percentile-based frequency, fixed threshold exceedances of temperature extremes and diurnal temperature ranges in the central and eastern TP. The results show that during 1958–2017 the TP has experienced increasing intensity and frequency of warm extremes and decreasing intensity and frequency of cold extremes, with almost all these changes larger than those in China and East China. The detection results and attribution analyses show that the anthropogenic (ANT) signal can be robustly detected in the trends for all extreme indices on the TP, and the natural (NAT) signal in some cases, too. The attributable contribution from ANT is estimated to be much larger than that from NAT for most indices. The study also indicates that the CMIP5 models may underestimate the magnitude of warming in some temperature extremes, especially the indices related to cold extremes. This should be kept in mind when informing adaptation decisions on the TP with projections based on the same models.

Authors: Puspita I B , Saputra F A
Published: October 2019

In order to fulfill the needs of built areas in Bandung encouraged land use changes in several areas. This land use change is one of the contributing factors to the increasing levels of carbon emissions in the air, which will have a further impact on the increasing urban temperature and Urban Heat Island phenomenon. Thus, this study was aimed to identify the effect of land use change on the increase of land-based emissions and temperatures in Bandung, as well as the trend in the future. This study utilized stock difference analysis method and the value of land-based emissions by using simple regression method. In addition, this study identified the effect of increase in emissions to the increase in temperature. The equation model produced from the regression was applied to identify the trend in 2031. Based on the results of the analysis, it was identified that land use change that occurred in 2003, 2011, 2014 and 2016 had an influence on increasing levels of carbon emissions in Bandung and had a significant influence on the increase in temperature. This temperature trend is projected to increase by an average of 1°C in 2031.

Published: October 2019

Agriculture can also be a source of environmental damage if poorly managed. The use of synthetic fertilizers and pesticides, changes in ecosystems and so on, are some examples of the damages to the environment due to excessive use of chemicals in agriculture. Conventional agriculture is considered easier, but the use of synthetic chemicals in conventional agricultural activities can disrupt biodiversity, soil fertility, ecosystems, and health. This study aims to calculate the economic assessment of organic horticultural agriculture by comparing the phenomenon of two types of horticultural agriculture. The survey was conducted by using random sampling to 70 respondents. The results show that the ratio of the benefits of horticultural organic farming is higher (3.06) compared to the benefits of conventional agricultural cultivation (1.73) with a significant difference. This is due to lower costs for fertilizers and organic plant protection, and also lower selling prices, even though the productivity of organic land is lower, but not significant. It is strongly recommended that conventional farmers move their farming methods to organic, because it will be more beneficial in terms of environmental sustainability as well as of the health of farmers, because it minimizes synthetic chemicals that are less safe for the environment and health, especially with excessive uses. The role of the government is highly expected, because without government support through either policy or assistance, farmers cannot optimally farm organically.

Published: October 2019

The aim of this paper is to analyze geographical pattern of economic activities from an evidence of large and medium manufacturing industry in Indonesia. By utilizing data for manufacturing industry for the 2010–2015, the exploratory spatial data analysis is applied to identify geographical distribution of economic activities. The result indicates that the spatial distributions of manufacturing industries are unevenly distributed indicating the clustered phenomenon pattern. A high concentration of manufacturing industries is depicted in several provinces, as well as in Java Island. The Moran’s I tend to decrease along the period of study. From the LISA, is apparent that there was a statistically significant high clustering. Only some provinces indicate significant clustering, such as in west Java, Banten, DKI Jakarta, and Central Java. The result of LISA indicates a positive spatial autocorrelation in research area revealing the existent cluster of economic activities. This paper attempts to contribute theoretical thought as well as empirical notes on spatial concentration in Indonesia.

Authors: Putri H M , Salim W
Published: October 2019

The development of the outer islands has not been widely discussed in literatures. As a peripheral area, its location which are remote and intersects with border areas of other countries caused the form of development to be different from the development in the mainland. One form of development on the outer island can be linked with cross-border cooperation. This study argued that based on the Natuna Island’s case study, trans-border development through cooperation between countries is a promising form for the development on the outer islands. But exploitation will occur if the government does not guard the process of development of the outer islands in the trans-border cooperation. The flow of goods that are not accommodated with appropriate access can make the outer islands being only as suppliers of goods that are not recognized by formal data. It caused their existence not being considered important in the cooperation between countries.

Nowadays, there is overwhelming evidence that regular physical activity has important and wide-ranging health benefits. The health risk and mortality factors were indirectly influenced by physical inactivity, the sedentary lifestyles developed by the car-oriented urban approach. That evidence supports the conclusion that physical inactivity becomes one of the most important public health problems of the 21st century, and may even be the most important. In order to encourage healthy urbanism, focusing on cultural and environmental aspects become necessary to Indonesian people. Soetomo General Hospital is a provincial health centre to provide a sense of security, comfort and convenience which are equal for all kinds of people, especially to walk. Therefore, environmental quality is a very important component to be considered. This paper utilizes character appraisal to find Soetomo General Hospital area’s physical condition. The result concludes design criteria for the built environment of the area. These design criteria are used as the main concept for elaborating the concept design of the place to improve its quality of environment towards healthy urbanism.

The development of urban settlements causes fast flow of urbanization. These condition leads to the growth of uncontrolled settlements which indicates Urban Sprawl Phenomenon. The phenomenon of urban sprawl begins with the need of the community to obtain better living standard, especially for residential functions. That residential function associated with urban sprawl is driven by settlement growth in certain locations (sporadic growth), and it is difficult to control (the impacts on the decline in environmental quality due to changes in certain land functions). By looking at these conditions, the understanding of the phenomenon of settlement growth must be conducted through the right approach. The approach views from an ecological element by examining a settlement in one large frame, total settlement patterns with a two-way classification scheme [1]. This research was conducted to understand the condition of settlement growth in order to find out the existing growth factors. The research area is located in the urban Situbondo with growth characteristics influenced by coastal and agriculture condition becoming the trigger of growth. Based on the results of the AHP calculation in Situbondo Regency, it is known that the most influential factor on settlement growth is natural factors with an assessment value of 0.243. Based on the morphological approach, the influence of natural factors shaping the pattern of ribbon settlement growth a small observation scale and the octopus pattern in the big range scale observation.

A planned human settlement is a settlement which is planned and controlled by government. In its development, this human settlement needs support from other areas, for example trade and service areas. However, this service trading area will give effect to residential areas if it’s not controlled, especially in its morphological aspects. There are many residential areas which are close to the service trade area and affected by this activity, for example in this case is Tanjung Duren Selatan, West Jakarta. This paper aims to study morphological aspect of planned human settlement affected by service and trading activities. This paper used qualitative method with mapping and parameter assessment based on aspects in human settlement morphology. The study shows that the trade and service sector in Tanjung Duren Selatan give the impact for housing morphology, such as increasing of land use for housing, solid formation dominates more than the formation of voids, morphological formation of figure ground theory, linkage and place that adjusts the impact.
Use of Organic Resins for Wood Modification
Authors: Balfas J.
Published: October 2019

Several Indonesian wood species were modified with two solutions of organic resins, i.e. shellac and damar which were diluted with methanol. The resin solutions were impregnated into wood blocks of coconut, rubber, fast grown teak and jabon. Physical and mechanical properties, and durability of the treated woods were determined to evaluate effects of the treatments. Results showed that effects of the treatments varied depending on wood species and kind of treatment. Wood blocks, treated to the highest weight percent gain (WPG), attained approximately 15% anti-shrink efficiency (ASE) after ten cycles of water saturation and drying. Coconut wood has higher permeability, solution uptake, retention and WPC than those of other three wood species. The ASE increased with an increase in the WPG. The resin modifications induced significant durability and mechanical strength improvements on all wood species.

Published: October 2019

Pirdot is one of forest plants that have the potential to be made into herbal tea. This study aims to obtain the best processing techniques and herbal tea formulas for processing pirdot leaves into herbal tea in the form of tea bags. The processing of pirdot herbal tea used three or five fresh pirdot leaves count from the shoots. Leaves processing was held in two ways, through a fermentation and without fermentation process. Organoleptic test of 15 panelists were carried out to test tea color, aroma and taste. Data were analyzed by applying Kendal’s tau multilevel correlation test. The results showed that the mixture of the top five leaves gave better result in color, aroma and taste of pirdot tea. Fermentation process also gave better results in terms of color, taste and aroma of pirdot tea compare to no fermented tea. However, optimum condition in fermentation process is still being studied.

The efficiency of timber harvesting and damage to residual stands is an aspect that needs serious attention because it has impacts on 1) increasing logs production, 2) saving natural forest resources, and 3) reducing the volume of the waste left in the forest has potential to create a risk of greenhouse gas emissions. This paper aims to provide information on the efficiency of timber harvesting and residual stand damage caused by harvesting activities in natural forests. The results showed that: 1) Efficiency of harvesting natural forest timber ranged from 75-86% with an average of 80.6% before applying the low impact (RIL) and varied from 82-95% with an average of 87.6% for the RIL techniques; 2). Damage to residual stands due to logging of non-RIL and RIL ranged from 27.76-40.71% with an average of 31.97% and 5-40% with an average of 22.20%, respectively; 3). The application of RIL techniques and the existence of sustainable forest management certification could improve the efficiency of timber utilization.

The burial and thermal histories of the Yingshan Formation in Well GC-6, Gucheng Low Uplift, were constructed in detail by using the PetroMod software. The results show that the Gucheng Low Uplift has experienced multiple stages of tectonic movement and the Hercynian movement had the most important impacts on the study area. The burial depth of the Yingshan Formation reached its maximum (>6300 m) in the Middle Devonian. The deep burial of strata and the high heat flow in the early times made the maturity of Yingshan Formation reached its maximum value of nearly 2.5%Ro in the Late Devonian and did not change anymore. The favorable paleo-structural background, good source-reservoir-seal assemblage and developments of deep strike-slip fractures made a high yield gas reservoir formed in the Yingshan Formation, Well GC-6.
