Tightly Coupling Input Output Economics with Spatio-Temporal Land Use in a Dynamic Planning Support System Framework

Planning support systems (PSSs) should generally be designed to promote the participation of stakeholders in planning and design processes through the delivery of useful, localized information, an ability to collect feedback, and an ability to model and test various ‘what-if’ scenarios. This paper focuses on such a PSS tool. The tool integrates the Land-use Evolution and Assessment Model (LEAM) with a Regional Economic Input-Output Model (REIM) in a tightly coupled computational process made accessible to stakeholders through a web-based PSS. The integrated tool allows for users to easily navigate the models and test land use and economic scenarios without expert assistance. It also keeps simulations updated with dynamic inputs and engages users in PSS development and application through responsive feedback to enhance plan-making abilities. In this paper, we demonstrate an application of the LEAM-REIM PSS in Sangamon County, Illinois. The application demonstrates an ability to provide more efficacious and detailed land use estimations through the connection of economic and land-use models, allowing users to easily engage with, navigate, and respond to scenario tests. We discuss the PSS tool, model integration approach, and detailed application to assess its usefulness in urban planning and design. We also propose some opportunities for further research.
The online community knowledge flows: distance and direction

ABSTRACT Whilst the role of online communities (OCs) in knowledge exchange and generation has been widely discussed, limited research exists on the distance and direction of OC knowledge flows. In this paper, we examine this issue by taking the case of an industry-founded OC that rendered around the use of a specific Enterprise Resource Planning (ERP) module used by public sector organisations. Through a grounded analysis approach, we extend literature on OCs by identifying user-generated practices that enable knowledge flows in the online space as well as by examining the travels of these knowledge flows, taking particular account of the distance they cover and the direction they take. Findings point to within, outwards and inwards travels of OC-related knowledge flows showing a widely spread OC knowledge impact. The theoretical and practical implications of the study are discussed.
Nitrogen Modified Carbon Nano-Materials as Stable Catalysts for Phosgene Synthesis

The carbon-catalyzed reaction of Cl2 and CO constitutes the most important industrial route to phosgene. Although defects in carbon lead to surface chemical reactions, direct polarization of C-heteroatom bonds induces a more successful Cl2 catalytic activation, the rate-determining step in the overall catalytic cycle. The interplay between the electron-donating and -withdrawing ability of the incorporated nitrogen substituents on the formation and stabilization of active sites was examined by X-ray photoelectron and Raman spectroscopy. Mechanistic studies indicate that the polarized Cl2 induced by the direct interaction of Cl2 with a strongly electron-deficient carbon site in close proximity to a nitrogen substituent is essential for phosgene production. Nitrogen substitution into ordered carbon materials led to very active and stable carbon catalysts for COCl2 synthesis.
SAR image despeckling using deep CNN

Synthetic aperture radar (SAR) images are contaminated with noise called speckle that is multiplicative in nature. The presence of speckles in SAR images makes it impossible to understand and interpret for extensive range of applications. However, certain characteristics of SAR and the ability to function irrespective of weather conditions, are making such images worth processing in order to be able to extract relevant information. A despeckling model is proposed that uses deeper convolutional neural networks, which was never used before, as far as authors are concerned, for diminishing speckle in noisy SAR images. Multiple skip connections from the ResNet model are also employed in authors’ proposed architecture. In order to maintain uniformity, a formula to be followed while applying skip connections is also derived. A hybrid loss function is developed to train the network more consistently to achieve the desired output. Experiments on simulated SAR images using the NWPU-RESISC benchmark are conducted and tested on real TerraSAR-X images and compared with the state-of-the-art techniques. Results show that the proposed method achieved considerable improvements compared to state-of-the-art methods with PSNRs 27.02, 24.60, and 22.01 for looks 10, 4, and 1, respectively.
How to Assess the Ecological Status of Highly Humic Lakes? Development of a New Method Based on Benthic Invertebrates

Highly humic lakes are typical for the boreal zone. These unique ecosystems are characterised as relatively undisturbed habitats with brown water, high acidity, low nutrient content and lack of macrophytes. Current lake assessment methods are not appropriate for ecological assessment of highly humic lakes because of their unique properties and differing human pressures acting on these ecosystems. This study proposes a new approach suitable for the ecological status assessment of highly humic lakes impacted by hydrological modifications. Altogether, 52 macroinvertebrate samples from 15 raised bog lakes were used to develop the method. The studied lakes are located in the raised bogs at the central and eastern parts of Latvia. Altered water level was found as the main threat to the humic lake habitats since no other pressures were established. A multimetric index based on macroinvertebrate abundance, littoral and profundal preferences, Coleoptera taxa richness and the Biological Monitoring Working Party (BMWP) Score is suggested as the most suitable tool to assess the ecological quality of the highly humic lakes.
Counting Pig using Marker-Controlled Watershed Segmentation

In India pig farming is one of the profitable livestock businesses and most of the farmers are successful in rearing commercial pig business. But rearing of pig is still unorganized endeavor that requires adoption of science and technology to increase production, monitor the livestock, reduce enterprise cost, automate growth management, monitor healthy environmental conditions for pigs which will leads to increase in farmer’s profit and reduce manpower (1,2). In large scale pig farming, counting of pig is also one of the challenging issues. Currently, pig counting is very important in large scale pig production management. Counting pig accurately can help farmers in improving pig management by reducing unnecessary loss in feeding, cost reduction in piggery construction etc (3,4).
No-Touch Harvesting in Off-Pump Coronary Artery Bypass Grafting With Sequential Saphenous Vein Grafting: A Single-Centre Prospective Randomized Controlled Trial

Background: The main graft material for coronary artery bypass grafting (CABG) is the combination of the internal mammary artery and great saphenous vein. The patency rate of vein grafts is considered not ideal; more studies support that the no-touch (NT) procedure can improve the patency rate of vein grafts. However, it is not clear that the NT technology is used in the sequential saphenous vein grafting during off-pump coronary artery bypass surgery. This study explored whether the NT technique is as safe and effective as the conventional technique in off-pump coronary artery bypass surgery using sequential vein grafts.Methods: This was a prospective single-centre randomized controlled clinical trial. A total of 200 patients undergoing off-pump coronary artery bypass grafting in the sequential saphenous graft were randomly assigned to two groups: the no-touch (NT) and conventional (CON) groups. Perioperative and postoperative data were collected during the hospital stay. The occlusion of sequential grafts was measured by cardiac computed tomography angiography (CCTA) 3 months post CABG. Leg wound complications were followed up. The mean diameter of sequential grafts for the first 100 patients was measured using CCTA 3 months after the operation.Results: The primary endpoint was that there was no difference in occlusion of sequential venous grafts between the two groups (NT: 9/180 (4.4%), CON: 5/194 (1.5%), p=0.22). Similarly, there were no differences in composite clinical events (NT: 2/91 (2.2%), CON: 1/96 (1.0%), p=0.96). There was no difference in leg wound complications between the two groups (NT: 8/91 (8.8%), CON: 4/96 (4.2%), p=0.20). However, there was a significant difference in the average diameter of sequential grafts between the two groups (NT: (2.98±0.42), CON: (3.26±0.51), p=0.005). Conclusions: The early clinical results suggest that the NT technique is as safe and effective as the conventional technique in sequential grafting in off-pump coronary artery bypass surgery. The sequential graft early expansion in the NT technique is not as pronounced as that in the conventional technique, which may have a long-term protective effect on the grafts.Trial Registration: Registered 1 November 2018, ClinicalTrials.gov NCT03729531, http://www.clinicaltrials. gov
Biometric and reproductive characteristics of the King Tiger Plecos Hypancistrus sp. “L-333” (Siluriformes: Loricariidae) endemic to the lower Xingu River (Pará, Brasil)

This research analyzed the biometrics and reproductive characteristics of a group of Hypancistrus sp. L-333 (King Tiger Plecos) in order to gather biological information and aid the rearing of the species in captivity, thus supporting its natural conservation. This species has a natural distribution that is restricted to the lower Xingu River, and is currently threatened by the hydroelectric projects in the region. The acquired specimens were measured, weighed and classified according to sex based on morphometric characteristics (evidence of secondary sexual characteristics) that were later confirmed by dissection. A total of 32 individuals, 16 males and 16 females were identified. Although the length-weight ratio did not present significant differences, the results revealed that the species has secondary sexual dimorphism. The odontodes were more developed in the mid-lateral region of the body, post-dorsal region, caudal peduncle and in the first ray (ossified) of the pectoral fin in males. Histological analyses of the gonads confirmed that all of the fish were adult individuals. The diameter of the oocytes ranged from 0.14 to 2.0 mm, presented three distinct modes, and were synchronous in more than two groups, which evidences batch spawning. Fecundity was low, between 35 and 54 oocytes in the largest batch. This information is novel and important for the identification of reproductive groups, and is aimed at breeding in captivity so that these resources can be exploited in a sustainable way, without harming the already threatened natural stocks.
A new Cyrtodactylus (Squamata: Gekkonidae) from Binh Thuan Province, southern Vietnam

We describe a new species of Cyrtodactylus on the basis of two specimens collected from Ta Kou Nature Reserve, Binh Thuan Province, southern Vietnam. Cyrtodactylus chungi sp. nov. is distinguished from the remaining Indochinese bent-toed geckos by a combination of the following characters: relatively small body size (SVL up to 68.5 mm); a continuous neckband; 5 or 6 irregular transverse dorsal bands; 11 or 12 bands on original tail; keeled tubercles present on dorsum, posterior limbs and tail; 17 or 18 irregular dorsal tubercle rows; 30 or 31 ventral scale rows; ventrolateral skin folds indistinct; an angular series of seven precloacal pores in male and six pitted, enlarged precloacal scales in female, each series separated by a diastema of undifferentiated scales from 4–6 enlarged, poreless femoral scales; median subcaudals slightly enlarged; 17–20 subdigital lamellae under the fourth toe. Based on molecular analyses of the fragment of mitochondrial gene cytochrome c oxidase subunit I (COI), the new species is recovered as the sister taxon to Cyrtodactylus cattienensis s. str. with a genetic divergence of more than 9%. In phylogenetic analyses, the new species is recovered as a member of the Cyrtodactylus irregularis species group.
Users’ Perception on Their Experience with FamPay

The objective of this paper is to determine customer satisfaction with FamPay. Since marketing strategies are positively associated with customer satisfaction, organizations need to design customer-value driven marketing strategies to satisfy customer’s needs. Thus, several organizations, such as FamPay, have moved away from mass marketing and toward target marketing. The study used a quantitative method with questionnaires to collect data from respondents. The findings indicated that marketing strategies have impact on the customer satisfaction.
Climate migration and the UK

This article discusses the relationship between climate change and migration in the context of the UK. After a brief overview of climate migration scholarship, it examines the framing of climate migration as a crisis in UK policy discourse, highlighting the disjuncture between policy and academic scholarship in this respect. Subsequently, it examines the reasons for this schism, exploring both the framing of climate migration within the UK media landscape and the securitisation of the topic within UK government policy. Finally, the article explores how the UK�s political landscape undergirds the political logic of climate finance, emphasising the role of British domestic politics in shaping the boundaries and direction of climate change as it manifests in governance. The article closes by exploring potential new directions in UK climate migration policy.
On emerging furnace design methodology that provides substantial energy savings and drastic reductions in CO2, CO and NOx emissions

Recent developments in heat recovery systems allow for preheating of combustion air up to temperatures of 1300 °C and, thus, fuel savings up to 60% are achievable. In conventional burner/furnace designs, the higher the combustion air temperature the higher the NO x emissions. However, the most recent developments allow for low NO x combustion using high temperature combustion air. The objective of this paper is to establish conditions under which industrial furnaces should be operated in order to maximize the efficiency and minimize the pollutant emissions including carbon dioxide. To this end, semi-industrial scale experiments have been carried out using natural gas and vitiated air at 1300 °C. A Nippon Furnace Kogyo burner that features a central air jet and two fuel gas injectors was used. Comprehensive in-furnace measurements of velocities, temperature, gas composition (O 2 , CO 2 , CO, H 2 , NO, CH 4 ) and radiation have been carried out. The furnace was operated under conditions resembling a well-stirred reactor; the temperature and chemistry fields were uniform all over the furnace. Almost the whole furnace volume was filled with combustion products containing 2-3% oxygen at temperatures in the range 1350-1450 °C, despite the high temperature (1300 °C) of the vitiated air. The natural gas jets entrained many of the combustion products before they mixed with combustion air. This mode of combustion resulted in high and uniform heat fluxes and low NO x and CO emissions. It was concluded that industrial furnaces of tomorrow are likely to be designed as well-stirred reactors equipped with high efficiency heat regenerators. Conventional burners will be either replaced with individual fuel and air injectors or substantially redesigned to facilitate uniformity of Combustion conditions within the furnace.
Facile synthesis of MOF-derived Mn2O3 hollow microspheres as anode materials for lithium-ion batteries

In this article, we report a facile and scalable route for the fabrication of Mn2O3 hollow microspheres by direct pyrolysis of Mn-based metal–organic frameworks at 450 °C with a heating rate of 10 °C min−1 in air. The effect of the heating rate on the morphology of the final samples has been also investigated. When evaluated as an anode material for LIBs, these Mn2O3 microspheres exhibited a reversible and stable capacity of 582 mA h g−1 after 60 cycles at a current density of 100 mA g−1. The improved capacity and excellent cycling stability of the as-prepared Mn2O3 microspheres could be attributed to the porous hollow structures, which can reduce diffusion length for lithium ions and electrons, and also can enhance structural integrity for buffering the volume expansion during the discharge/charge processes.
High-resolution ultrasonic resonator measurements for analysis of liquids

This paper describes the basic principles and the key components of the resonator technique for high-resolution ultrasonic measurements in liquids and illustrates its application to the analysis of food colloids. In this technique the ultrasonic parameters of liquids are obtained through the measurements of resonance characteristics of acoustic resonators. Modern advances in electronics and in the construction of ultrasonic resonators combined with the scientific background of interpretation of ultrasonic characteristics obtained in the last decade make high-resolution ultrasonic measurements a powerful tool in different kinds of analysis of food colloids in research and industry.
Effects of Solar Illumination and Substorms on Auroral Electrojets Based on CHAMP Observations

We investigate the effects of solar illumination and the substorm process on the auroral electrojets using CHAMP high‐resolution magnetic field data obtained over a period of 10 years. The eastward electrojet was found to be proportional to the ionospheric conductance induced by solar irradiation over the whole day. More notably, a stronger westward current was detected in times of lower fluxtube‐integrated conductance in both hemispheres. The relative spatial distribution and evolution of the westward electrojet and field‐aligned current (FAC) during the substorm periods were also investigated. The position of the westward current coincided with that of the upward FAC in 2000–2200 magnetic local time (MLT), in keeping with the structure of a westward traveling surge. Furthermore, the upward FAC in the local time sector of the poleward of the westward electrojet was supplied mostly by the remote closure current. The downward FACs in the poleward and upward FACs in the equatorward of the westward electrojet existed in the MLT sectors after 2200 h. Finally, the ratio of the peak intensity of the westward electrojet to that of the meridional Pedersen current, in the 2000–2200 MLT sector increased by about 250%, and the value in the 2200–0200 MLT increased by about 10%–20%. These results provide observational evidence of the increased efficiency of the Cowling channel in the night‐time during substorm periods and contribute to our understanding of the formation mechanism of the auroral electrojet.
Development of a Continuous Photochemical Benzyne-Forming Process

Abstract A continuous-flow process is presented that enables the safe generation and derivatization of benzyne under photochemical conditions. This is facilitated by a new high-power LED lamp emitting light at 365 nm. The resulting flow process effectively controls the release of gaseous by-products based on an adjustable backpressure regulator and delivers a series of heterocyclic products in a short residence time of 3 minutes. The robustness of this methodology is demonstrated for the rapid generation of benzotriazoles, 2H-indazoles and various furan-derived adducts, facilitating the preparation of these important heterocyclic scaffolds via a simple and readily scalable flow protocol.
Response of Lower Sacramento River phytoplankton to high-ammonium wastewater effluent

Since the 1980s, the San Francisco Bay Delta ecosystem has experienced large declines in primary production. Hypothesized reasons for this decline include (1) suppression of nitrate (NO3−) uptake, and thus phytoplankton growth, due to high concentrations of ammonium (NH4+), and (2) wastewater NH4+-induced changes in phytoplankton community composition away from large-celled diatoms. These twin hypotheses implicate NH4+ loading from the Sacramento Regional Wastewater Treatment Plant effluent outfall in explaining declines in primary production in the region. They have been controversial within the water resources management community and have stimulated a lengthy public scientific and regulatory debate. Here, in an effort to resolve this debate, we present results from a 48-h incubation experiment with surface water from both upstream and downstream of the Sacramento Regional Wastewater Treatment Plant effluent outfall, a major source of NH4+ loading to the ecosystem. We amended this water with either NH4+, NO3−, or full wastewater effluent. All assays were incubated under high light (52% of incident irradiance) or low light (6% of incident irradiance). NO3− uptake rates were suppressed to near zero in all treatments with either added NH4+, added wastewater effluent, or high in situ NH4+ concentrations. Yet, phytoplankton uniformly grew well on all dissolved inorganic nitrogen sources, including effluent and NH4+. Diatom species were the most abundant taxa at all stations, and diatom cell abundances increased at greater rates than all other taxa over the course of the experiment. Among all treatments, the light treatment had the greatest effects on chlorophyll a accumulation and phytoplankton growth rates. Our results suggest that high NH4+ loading is not a driver of the lower productivity in the San Francisco Bay Delta. Although phytoplankton preferred NH4+ to NO3− when both were available in our experiment, the form of dissolved inorganic nitrogen had no effect on growth rates or species composition.
Microencapsulated dimethyl terephthalate phase change material for heat transfer fluid performance enhancement

Micro‐phase change materials (micro‐PCMs) are proposed to increase the thermal conductivity and the thermal energy storage capacity of a heat transfer fluid (HTF). In this work, we have selected dimethyl terephthalate (DMT) to be used as a PCM for performance enhancement of a synthetic oil in the temperature range of approximately 100 to 170 °C. Silicon dioxide (SiO2) was used as the microencapsulant, because of its desirable properties as containment material, including thermal stability. The SiO2‐coated DMT micro‐PCM was characterized to determine relevant properties and its suitability for HTF performance enhancement. The SiO2‐coated DMT was found to completely disperse in the synthetic oil, Therminol SP, silicone oil, at and above 100 °C. FTIR, thermal diffusivity and differential scanning calorimetry measurements were carried out on the materials, and these tests demonstrated that the coated particles can be used for HTF enhancement in the temperature range of 100–170 °C and potentially higher temperatures if pressurized pipes/vessels are utilized.
