Dispersal of semi-fleshy fruits to rock crevices by a rock-restricted rodent
Authors: White Joseph D.M. , Midgley Jeremy J. 
Published: November 2017

Seed dispersal allows successive generations of plants to be mobile in space and time. Heeria argentea’s unusual fruit and its ubiquity in extremely rocky habitats, suggests that this tree requires a specialist disperser. We therefore investigated the dispersal ecology of H. argentea and Hartogiella schinoides. We found M. namaquensis rapidly removed H. argentea and H. schinoides fruits, moving them short distances within and between rock outcrops, and consumed only the pericarps. Birds were observed consuming H. schinoides, but not H. argentea fruits, suggesting M. namaquensis is its sole, specialist disperser. Most H. argentea seeds (65%) with removed pericarps germinated successfully, while intact fruits did not. We show rock outcrops represent fire refugia, allowing H. argentea trees to grow to large sizes, with small stems and a co-occurring, wind-dispersed tree, Widdringtonia nodiflora found away from these sites. This rodent–tree mutualism is perhaps the clearest global example of directed dispersal and shows that these endemic trees are highly adapted for survival in the southwestern Cape habitat and are not tropical relicts.

Significance:

The fruits of rock-restricted Cape trees are directly dispersed by rock rats to rock outcrops. This is the first description of rodent dispersal of fleshy fruits in South Africa.
This species-specific interaction allows for rapid germination of seeds and protection from frequent fires for adults. This rodent–tree mutualism is perhaps the clearest global example of directed seed dispersal.

High Intensity Interval Training or Moderate Intensity Continuous Exercise in Patients with Myocardial Infarction?
Authors: Themistocleous Irene C. , Stefanakis Manos 
Published: November 2017

Objectives: To determine the effects of high intensity interval training (HIIT) or moderate intensity continuous exercise (MICE) in patients with myocardial infarction (MI). Background: Cardiovascular diseases are the leading cause of mortality and morbidity globally causing a significant reduction in the quality of life of these patients. Participation of these patients in rehabilitation programs which involve a significant component of exercise seems to help by improving functional capacity and quality of life (QoL). Despite the beneficial effect of exercise, the type of exercise that yields the best results is yet to be determined.Methods: Three databases (MEDLINE, CINHAL and SportDirect) were searched in May-June 2017 for original articles regarding the effect of two types of exercise in patients with myocardial infarction. Randomized control trial studies which enrolled patients with myocardial infarction and studied the effects of HIIT and/or MICE, were included in this review. Data were extracted and summarised and all studies were assessed for bias.Results: Both forms of exercise seem to improve the relevant outcome measures such as functional capacity, QoL, walking distance, fatigue and function of the left heart. However HIIT seemed to be better in comparison with MICE in improving these outcomes. Several limitations and risk of bias have been identified and reported.Conclusion: Both HIIT and MICE are recommended for patients with MI. Further research is required to conclusively support the superiority of HIIT over other types of exercise.

Technology Focus: Drilling Technology (February 2009)
Authors: Menand Stephane 
Published: November 2017

Technology Focus
To reach reserves in increasingly complex wells, drilling challenges are numerous and very impressive, requiring highly skilled engineers who must deal with many disciplines, such as tubular and rock mechanics, hydraulics, data acquisition and processing, and modeling, among others. Nowadays, drilling is faced with several limits that intensify uncertainty and risks.
Hydraulics and mechanics issues illustrate these drilling limits. From a hydraulic point of view, because of narrow drilling margin (e.g., very small difference between fracture and pore pressure) coupled with inaccurate knowledge of what is happening downhole, automated control and measurements while drilling are required to maintain equivalent circulating densities within a tight margin. Indeed, the uncertainty of temperature and pressure downhole may be greater than the margin itself. As a result, this managed- or controlled-pressure drilling technology enables reducing lost circulation, formation fracturing, and differential sticking, and it enables close monitoring of static, dynamic, and transient hydraulic behavior.
From a mechanical point of view, because wells are deeper and temperatures and pressures are higher, drilling equipment is pushed to its mechanical and endurance limits. Even though it is recognized that new resistant and higher-strength material needs to be developed for the future, downhole measurements with a high-speed-telemetry drillstring will aid in determining accurate mechanical limits of existing technology. This information should lead to a better understanding of drillstring mechanics to prevent vibration, friction heating, wear, fatigue, and finally failure.
To reduce uncertainty on downhole mechanical and hydraulic conditions, one must measure accurately, transmit quickly, and react accordingly to make the best drilling decisions. Therefore, data processing and modeling are important aspects of measurements or control while drilling. To manage, and add value to, this massive amount of information collected downhole, real-time and accurate mechanics and hydraulics models are required. Future generations of drillers will have to push these technical limits even further.

Surface Tension of Crude Oils Containing Dissolved Gases
Authors: Katz D. L. , Monroe R. R. , Trainer R. P. 
Published: November 2017

Abstract
A formula for computing the surface tension of hydrocarbon mixtures has been developed based upon recent measurements of surface tension for the methane-propane system. Data on n-butane gasoline mixtures have been used to demonstrate that the formula applies to complex mixtures. Surface-tension data on heptane and heavier fractions of the equilibrium liquids containing dissolved gases previously reported permitted computation of the surface tension for these oil-gas systems at pressures to 8200 lb. per sq. in. The surface tension for crude oils containing dissolved gases at pressures above 3000 lb. per sq. in. may be expected to be below 2 or 3 dynes per centimeter and may be below 0.1 dyne per centimeter.

Introduction
The tension at the surface of a liquid in contact with a vapor is responsible for capillary action of liquids in porous solids. Methods of measuring surface tension either at atmospheric pressure or at elevated pressures are available. However, these measurements require rather elaborate apparatus and painstaking efforts to obtain reliable data, therefore it is desirable to have a method by which the surface tension of crude oils containing dissolved gases may be computed from the fractional analysis of the liquid.
Recent measurements on the surface tension of the methane-propane system under pressure have provided the basis for the establishment of a relationship by which the surface tension of hydrocarbon mixtures may be predicted from fractional analyses.

Forest, water and people: The roles and limits of mediation in transforming watershed conflict in Northern Thailand

Published: November 2017

This study focuses on watershed management in Northern Thailand, where conflict over forest, land and water-use is a prevailing problem. A characteristic of watershed conflicts is that they are often multifaceted and involve multiple stakeholders with different interests and values, consequently requiring conflict management approaches that are sustainable in their outcomes, including addressing the underlying causes of the conflicts. Drawing from a case study in Mae Tia Mae Tae watershed in Northern Thailand, this study explores how mediation by external third party can contribute to the transformation of conflicts in the watershed and how the broader institutional contexts in which the conflict is embedded shapes the mediation outcomes. The study suggests that co-creation of mutual understanding and recognition of each party’s socio-cultural differences, including land-use practices, are critical in building trust and in how conflict transformation processes moved forward. Moreover, the ability of the mediator in facilitating the establishment of a deliberative institution (i.e. a watershed network committee) and agreed rules on forest utilization were also critical in maintaining long-term collaboration in the watershed and potentially preventing other conflicts arising in the future. Some issues, however, may threaten the continuity of the cooperation and sustainability of peace in the watershed, including the lack of structural reform that formally recognizes local people’s rights, insecure land tenure, and the absence of legal recognition for the watershed network committee as a legitimate mechanism for watershed decision making. The paper discusses these findings by comparing it with those from our previous studies in other locations (Cambodia, Indonesia and Western Thailand) to strengthen the insights from Northern Thailand. Finally, the research puts forward some recommendations for reforms and to strengthen the use of effective mediation, to achieve transformative outcomes, in conflicts of this nature. iation, to achieve transformative outcomes, in conflicts of this nature.
Social Forestry - why and for whom? A comparison of policies in Vietnam and Indonesia

Published: November 2017

Community forestry or social forestry (henceforth referred collectively as SF) programs have become new modes of forest management empowering local managers and hence, allowing integration of diverse local practices and support of local livelihoods. Implementation of these initiatives, however, face multiple challenges. State-prescribed community programs, for example, will remain isolated efforts if changes in the overall economic and social governance frameworks, including the devolution of rights to local users is lacking. Financial sustainability of these measures remains often uncertain and equity issues inherent to groups and communities formed for SF, can be exacerbated. In this article, we pose the question: Whose interests do SF policies serve? The effectiveness of SF would depend on the motivations and aims for a decentralization of forest governance to the community. In order to understand the underlying motivations behind the governments’ push for SF, we examine national policies in Vietnam and Indonesia, changes in their policies over time and the shift in discourses influencing how SF has evolved. Vietnam and Indonesia are at different sides of the spectrum in democratic ambitions and forest abundance, and present an intriguing comparison in the recent regional push towards SF in Southeast Asia. We discuss the different interpretations of SF in these two countries and how SF programs are implemented. Our results show that governments, influenced by global discourse, are attempting to regulate SF through formal definitions and regulations. Communities on the other hand, might resist by adopting, adapting or rejecting formal schemes. In this tension, SF, in general adopted to serve the interest of local people, in practice SF has not fulfilled its promise.
Three-body abrasive wear behaviour of metastable spheroidal carbide cast irons with different chromium contents

Published: November 2017

Abstract
The effect of heat treatment and chromium contents (up to 9.1 wt.%) on the wear resistance of spheroidal carbide cast iron (9.5 wt.% V) was studied using optical and scanning electron microscopy, X-ray diffractometry, dilatometry and three-body abrasive testing. It was found that quenching from 760 °C and 920 °C improved the alloys’ wear resistance compared to the as-cast state due to the formation of metastable austenite transforming into martensite under abrasion. The wear characteristics of alloys studied are 1.6 – 2.3 times higher than that of reference cast iron (12 wt.% V) having stable austenitic matrix. Chromium addition decreases surface damage due to the formation of M
7C3 carbides, while it reduces wear resistance owing to austenite stabilization to abrasion-induced martensite transformation. The superposition of these factors results in decreasing the alloys’ wear behaviour with chromium content increase.

Abstract
Hybrid morphology radio sources (HyMoRS) are a rare type of radio galaxy that display different Fanaroff–Riley classes on opposite sides of their nuclei. To enhance the statistical analysis of HyMoRS, we embarked on a large-scale search of these sources within the international citizen science project, Radio Galaxy Zoo (RGZ). Here, we present 25 new candidate hybrid morphology radio galaxies. Our selected candidates are moderate power radio galaxies (

W Hz−1 sr−1) at redshifts

. Hosts of nine candidates have spectroscopic observations, of which six are classified as quasars, one as high- and two as low-excitation galaxies. Two candidate HyMoRS are giant (

Mpc) radio galaxies, one resides at the center of a galaxy cluster, and one is hosted by a rare green bean galaxy. Although the origin of the hybrid morphology radio galaxies is still unclear, this type of radio source starts depicting itself as a rather diverse class. We discuss hybrid radio morphology formation in terms of the radio source environment (nurture) and intrinsically occurring phenomena (nature; activity cessation and amplification), showing that these peculiar radio galaxies can be formed by both mechanisms. While high angular resolution follow-up observations are still necessary to confirm our candidates, we demonstrate the efficacy of the RGZ in the pre-selection of these sources from all-sky radio surveys, and report the reliability of citizen scientists in identifying and classifying complex radio sources.
Magnetic Field Amplification in Supernova Remnants
Authors: Xu Siyao , Lazarian Alex 
Published: November 2017

Abstract
Based on the new findings on the turbulent dynamo in Xu & Lazarian, we examine the magnetic field amplification in the context of supernova remnants. Due to the strong ion-neutral collisional damping in the weakly ionized interstellar medium, the dynamo in the preshock turbulence remains in the damping kinematic regime, which leads to a linear-in-time growth of the magnetic field strength. The resultant magnetic field structure enables effective diffusion upstream and shock acceleration of cosmic rays to energies above the “knee.” Differently, the nonlinear dynamo in the postshock turbulence leads to a linear-in-time growth of the magnetic energy due to the turbulent magnetic diffusion. Given a weak initial field strength in the postshock region, the magnetic field saturates at a significant distance from the shock front as a result of the inefficiency of the nonlinear dynamo. This result is in a good agreement with existing numerical simulations and well explains the X-ray spots detected far behind the shock front.
