Objective: To identify changes in microcirculation and metabolic activity in soft tissues in an experimental explosive wound after local administration of hyaluronic acid and to determine the mode of its use, in which these changes are sanogenetically significant.Methods: The experiments were approved by the local Ethics Committee and performed on 96 male Wistar rats weighing 300-350 g. at the age from 4 to 4.5 months. The design of the study included the following stages: wound modeling (according to the method which has RF patent for invention No. 2741238); closing the wound with a pressure bandage and fixing it with a patch; primary surgical treatment of the wound 3 hours after the injury; fan (5-6 points) intramuscular injection of hyaluronic acid (“Hyalift” medication) diluted with 0.9% sodium chloride solution to 1.75% (total volume – 0.5-0.8 ml); dynamic observation accompanied by daily wound dressings (chlorhexidine, and Levomekol ointment) until its epithelialization and by intramuscular administration of antibacterial drug (Gentamicin sulfate) during the first 7 days after the injury. The study of microcirculation and metabolism of tissues of the injury zone using laser Doppler flowmetry, optical tissue oximetry and laser fluorescence diagnostics (using the device "Lakk-M") was conducted on the 7th, 14th and 28th day after the injury.Results: Early (3 hours after the injury) local application of HA in case of an explosive soft tissue wound improves the perfusion characteristics of microcirculation, has a positive effect on the trophism and oxidative metabolism of skeletal muscles, and reduces the time of wound healing. The early administration (3 hours after the injury) of HA in the mode: locally in the para volar tissues, after 3 hours (at the end of the primary surgical treatment of the wound) and additionally after 24 hours after the injury is considered to be the most effective.Conclusions: Intramuscular injection of hyaluronic acid into the para volar tissues in the first hours after the wound in case of an explosive soft tissue wound is a sanogenetically justified method of correcting the wound process.

Abstract
An AlGaN/GaN heterojunction bipolar transistor (HBT) with N-p-n configuration was fabricated by the “regrowth-free” method, resulting in a contamination-free emitter-base AlGaN/GaN heterojunction. The low-bias-power-based low-damage inductively coupled plasma–reactive ion etching was employed in this study for emitter mesa definition instead of the conventional selective-area-regrowth technique. The method successfully minimized the etching-induced damage in the p-GaN base layer and the contamination at the emitter-base AlGaN/GaN heterojunction. Consequently, the fabricated device exhibited a high current gain of 25, the highest current density of 15.0 kA cm−2, and the lowest on-state voltage offset of 0.75 V ever reported for AlGaN/GaN HBTs.

Abstract
High-efficiency broadband second-harmonic-generation (SHG) of YCa4O(BO3)3 (YCOB) crystal was demonstrated for the first time. The theoretical calculation predicted that the retracing point wavelength for type-I SHG of YCOB crystal was at around 1650 nm, which was proved by the followed phase-matching experiment. With a tunable femtosecond laser as the light source, the type-I SHG experiments of YCOB crystal were performed in the range of 1550–1700 nm. Compared with other broadband SHG crystals, YCOB crystal presented the highest optical conversion efficiency of 58%, the largest spectral bandwidth conversion ratio of 65%, and the broadest wavelength acceptance bandwidth of 118.8 nm·cm1/2.

<div>This paper outlines a new approach to detect anomalies in hyperspectral images based on peripheral pixels. The proposed methodology contains two main steps. First, a new distance score is introduced based on the sigmoid function and root mean square error (RMSE). We estimate how likely the target pixel is an anomaly by averaging the new metric over its neighboring window.</div><div>	Second, a state-of-the-art method is applied to eliminate unacceptable objects according to their size. In this light, the objects whose size is out of an acceptable interval are removed.</div><div>	Comprehensive experimental evaluations have been conducted to confirm that the proposed method significantly outperforms several recent algorithms in accuracy and computational time.</div>
Totalising Partial Algebras
Authors: Bergstra Jan Aldert , Tucker John V. 
Published: March 2022

We will examine totalising a partial operation in a general algebra by using an absorbtive element, bottom, such as an error flag. We then focus on the simplest example of a partial operation, namely subtraction on the natural numbers: n - m is undefined whenever n < m. We examine the use of bottom in algebraic structures for the natural numbers, especially semigroups and semirings. We axiomatise this totalisation process and introduce the algebraic concept of a team, being an additive cancellative semigroup with totalised subtraction. Also, with the natural numbers in mind, we introduce the property of being generated by an iterative function, which we call a splinter. We prove a number of theorems about the algebraic specification of datatypes of natural numbers.
Estimating Technical Efficiency and its Determinants in the Coconut Plantations: The Case of Kurunegala Plantations Limited, Sri Lanka

Published: March 2022

This study estimated the Technical Efficiency (TE) of coconut production in Sri Lanka using the stochastic frontier production function procedure. Data on inputs and coconut production recorded by Kurunegala Plantations Limited from 2000 – 2018 were used for the analysis. The stochastic production frontier in Cobb-Douglas form and the inefficiency model were estimated by single-step Maximum Likelihood method using STATA 14 computer software package treating coconut yield as the dependent variable and fertilizer, rainfall, labor, chemicals, tractor hours, mulching harrowing/plowing, agro-ecological zones, education level of the managers and bearing coconut extent as independent variables. Results revealed that TE of coconut production ranged from 81-98%, with an average of 88%, indicating that there is scope for increasing the production by as much as 12% without increasing inputs and simply using a higher technology level. The outcome of the analysis shows that inorganic fertilizer, rainfall, labor, tractor hours, and mulching are kind positive and significant. In contrast, agro-chemicals such as weedicides, fungicides and pesticides and plowing/harrowing did not show a significant contribution to coconut production. In respect of the farm and farmer-specific characteristics, the size of the estate has a positive relationship with technical inefficiency, meaning that smaller estates are more efficient than larger estates. It also shows that the agro-ecological zones and educational level have no significant effect on the efficiency of coconut production. The results highlight the need for government and private sector assistance in improving the efficiency of smallholders and promoting access to productive inputs.

EVALUATION OF POLICIES ON THE DEVELOPMENT OF PREFABRICATED CONSTRUCTION IN CHINA: AN IMPORTANCE-PERFORMANCE ANALYSIS
Authors: Gan Xiaolong , Liu Lanchi , Wen Tao 
Published: March 2022

ABSTRACT
Prefabricated construction (PC) has been regarded as a critical approach to address the challenges confronted by the construction industry in achieving sustainable development. Despite the Chinese government having issued various policies to promote the development of PC, this field remains in its infancy, thus suggesting an unsatisfactory policy system. Few studies have been conducted on the policy evaluation of target stakeholders who are closely related to the policy goal. To fill this knowledge gap, this study innovatively adopts importance-performance analysis to evaluate the policies on PC development with reference to the policy framework, including environmental, demand, and supply instruments. First, the explicit importance and perceived performance levels of policy instruments were investigated through a questionnaire survey conducted in Chongqing, China. Gap analysis indicated that all these policy instruments failed to meet the demand of target stakeholders. The implicit importance of policy instruments was obtained by using partial correlation analysis. Grid analysis revealed that the policy instruments can be divided into basic, key, excitement, and secondary factors, and finally, the most crucial areas of policy improvement were determined. The results of this study indicate different policy instruments were perceived with different importance in improving the policy system of PC development, and stakeholders showed heterogeneous needs of policy instruments of PC development. Generally, all the policy instruments were perceived as negative, and more attention should be paid to the policy instruments of infrastructure construction, technical development, talent support, economic incentives, public services, and guide information. This study confirmed the applicability of importance-performance analysis in policy evaluation and provided new insights into effectively improving the efficacy of policy system in promoting the development of PC.
INTRODUCTION OF NEW DAYLIGHTING METRICS FOR HEALTH, WELLBEING, AND FEASIBILITY: A STUDY OF THE INDOOR BUILDING ENVIRONMENT
Authors: Lee Jaewook , Boubekri Mohamed 
Published: March 2022

ABSTRACT
This study investigates the applicability of a new daylighting metric based on human health, an emerging framework for evaluating the effect of daylight on building occupants. Procedures based on modeling annual daylight availability are used to determine the mapping of daylight distribution on a daily, seasonal, and yearly basis. Literature review and experimental studies were performed to propose the new day-lighting metrics for health and wellbeing. The proposed metrics have two broad criteria, including daylighting level, timing, and duration. The two details are as follows: (1) 400 lux for 5 hours (2K lux·h) in the daytime; and (2) 500 lux for 1 hour (0.5K lux·h) in the early morning, 8AM–9AM. To verify the applicability of the proposed daylighting metrics to current buildings, sample buildings were selected and daily, spatial and seasonal differences were simulated through computer visualization techniques. Moreover, we evaluated the application of the daylighting metric on the building layout and compared the new daylighting metric for health and wellbeing with conventional daylighting metrics.
A COMPARATIVE LIFE CYCLE ANALYSIS OF NEAR-ZERO ENERGY BUILDINGS WITH A FOCUS ON ENVELOPE INSULATION
Authors: Moradibistouni Milad , Vale Brenda , Isaacs Nigel 
Published: March 2022

ABSTRACT
Near-zero energy buildings are known to have the potential to reduce energy consumption and consequent emissions. This article uses a life cycle analysis approach to evaluate the effects of using different insulating materials on the lifetime energy consumption of a near zero conditioning energy case study house in Wellington, New Zealand, by assessing the environmental impacts of a number of insulation options. The question addressed is whether using thick layers of insulation with high R-values in a building envelope is always a reliable approach to mitigating the impact of the built environment on the planet. The results show no significant difference between the environmental impacts of insulating the house using polyurethane and using no insulation in the first 28 years. The further discussion shows the energy profile used for processing the materials, construction and operating the buildings are not always the same, and this has a significant impact on the building’s environmental footprint. There needs to be a balance between both the value and profile of building operating and embodied energy.

BASICS OF BUILDING WITH MYCELIUM-BASED BIO-COMPOSITES
Authors: Ghazvinian Ali , Gursoy Benay 
Published: March 2022

ABSTRACTMycelium-based composites (MBC) are biomaterials presenting renewable and bio-degradable alternatives for a wide range of design and manufacturing processes, including the building industry. MBC result from the incomplete growth of mycelium, fibrous root systems of fungi. They can turn urban and agricultural waste into high-end products. Existing research shows that MBC can reduce fossil fuels’ reliance and embodied energy and decrease building waste. Architects recently designed and built a wide range of experimental projects with MBC. In parallel, there is a growing body of work on MBC by scholars from different disciplines, such as mycology, material science, and mechanical engineering, focusing on assessing and enhancing the material properties of MBC for various applications.In this paper, we first provide essential knowledge on the cultivation of MBC for architectural applications. Next, we analyze some of the prominent architectural prototypes with MBC to exemplify the architectural potentials of MBC and uncover the constraints and affordances of this biomaterial when used in an architectural context. Finally, we review and synthesize the existing literature on MBC from different disciplines providing a guide for architects to cultivate and enhance the material properties of MBC for architectural goals.

Published: March 2022

ABSTRACT. Rhodamine B (RhB) is one of the prominent dyes discovered to be carcinogenic and mutagenic substance present in the ecosystem. Alteration of the characteristics of TiO2 through modification with clay influences the behavior of some organic molecules at its surface, and thus its photocatalytic properties. This study investigates the photocatalytic degradation of RhB using TiO2-activated kaolinite composite (TiO2-AKC). TiO2-AKC was prepared in absolute ethanol and characterized using SEM, EDX, TEM, BET and FTIR. The photodegradation of RhB using TiO2-AKC at room temperature under visible-light was studied at various time intervals and the concentration of RhB was monitored using Ultraviolet-Visible spectrophotometer. Characterisation of TiO2-AKC revealed an adequate distribution of TiO2 over the AKC surface, with an enhanced surface area (TiO2-AKC 808 m2g-1, TiO2 50.0 m2g-1, AKC 20.6 m2g-1) necessary for effective degradation. The degradation was efficient in TiO2-AKC than in sole TiO2 resulting in 99.51% and 88.35%, respectively. The experimental data was analysed using zeroth and first order kinetics, parabolic diffusion, and modified Freundlich model. The degradation kinetics conforms to first order kinetics in TiO2-AKC and sole TiO2. The mechanism of the degradation using TiO2-AKC fit into modified Freundlich model and parabolic diffusion model while sole TiO2 was best described by parabolic diffusion model.
