Enzymes possessing many excellent properties such as high selectivity, consuming less energy, and producing less side products or waste have been widely applied as biocatalysts in pharmaceutical production and many industries such as biofuel, biomaterials, biosensor, food, and environmental treatment. Although enzymes have shown its potential as biocatalysts for many industrial applications, natural enzymes were not originated for manufacturing process which requires harsh reaction conditions such as high temperature, alkaline pH, and organics solvents. It was reported that reduction of final conversion of several enzymatic reactions was declined at high temperature. Protein engineering to improve the enzymes’ thermostability is crucial to extend the use of the industrial enzymes and maximize effectiveness of the enzyme-based procesess. Various industrial enzymes with improved thermostability were produced through rational protein engineering using different strategies. This review is not aimed to cover all successful rational protein engineering studies. The review focuses on some effective strategies which have widely used to increase the thermostability of several industrial enzymes through introduction of disulfide bonds and introduction of proline.

Agriculture is responsible for generating large amounts of waste that are not adequately managed in terms of their environmental treatment and economic administration. This work uses giant reed, which was traditionally used as a construction material in eastern areas of Spain. Nowadays, it is no longer used, which has led to its rapid, autonomous, uncontrolled proliferation on river banks, making it a serious environmental hazard because this plant causes significant blockages of bridges and other infrastructure when uprooted by the strong currents that occur as rivers flood. The aim of this work is to develop wood and giant reed particleboards, which help to counter the high dependence on wood in industrial manufacturing by using an easily renewable resource. It will thereby be possible to achieve two general objectives: controlling the growth of a weed and obtaining a product (particleboards) from a waste material. Particleboards containing 9% urea formaldehyde composed of different proportions of sawmill wood and giant reed (0, 50, 70 and 100%) have been manufactured by applying two different pressures (2.1 and 2.6 MPa) and a temperature of 120 °C for 4 min in a hot plate press. Density, thickness swelling (TS) and water absorption (WA) after immersion in water, modulus of elasticity (MOE), modulus of rupture (MOR), internal bonding strength (IB) and screw holding strength (SH) have been tested according to european norms (EN) for wood boards. With the addition of 70% reed particles, the density, MOR and TS decrease and the MOE, IB and SH increase; therefore, adding giant reed particles to wood boards can improve their properties, bringing about considerable industrial and environmental benefits.

AbstractThis article provides an economic investigation into the underlying causes of industrial wastewater emissions. We examine the direct and the structural break-induced effect of national environmental regulation on industrial wastewater emissions. The results show that strict environmental regulation can partially offset the energy-induced effects imposed by the scale effects of foreign direct inflows and cause positive behavioral responses by either limiting coal usage or improving upon coal usage technology and shift towards clean energy sources. We find the absence of scale economies in the provision of environmental services in the industrial sector due to the poor nature of the technical processes of industries. We further highlight the importance of raising the investment in environmental treatment and embracing trade liberalization in the improvement of industrial wastewater management.

Background: The systematic use of music as an environmental intervention in nursing homes shows beneficial effects on patients’ health, safety, and quality of life in a care-related perspective. A county in Norway and a Nursing Education Department in a region of Norway collaborated on the project “systematic use of music as environmental intervention and quality of care in nursing homes” for nursing students. Methods: This study from Norway (2017) had a qualitative and explorative approach. The sample (n = 33) was strategically and conveniently selected. Seven different focus group interviews consisted of nursing students, practice counselors, teachers, and project leaders, representing three nursing homes and healthcare centers. Passive observation lasting two days in each of the six departments was executed in order to observe environmental treatment in practice. Results: The beneficial aspects of using music as an environmental intervention in nursing homes increased among the students, and contributed to improved interaction, communication, and development of care with the patients. Students who participated actively in musical interaction such as improvisation, singing, and music listening with the patients were committed and motivated. The staff and management showed varied enthusiasm for the project. Conclusions: If the systematic use of music as environmental therapy and quality of care in elderly care is to be successful, it seems vital to include this theme early in nursing education. By creating early involvement among nurses, it might influence, inspire, and encourage involvement among employees and management.

Abstract Pigs exposed to elevated ambient temperatures exhibit reduced daily gain, alterations in muscle and fat deposition, and decreased health. Negative aspects of gastrointestinal (GI) function, integrity, and permeability also occur. High-intensity sweeteners can ameliorate the negative effects of heat stress (HS) by increasing GI glucagon-like peptide-2 production while capsicum oleoresin has been shown to reduce inflammatory response. The effects of an artificial high-intensity sweetener and capsicum oleoresin (CAPS-SUC; TakTik X-Hit, Pancosma, Switzerland) on growth performance of pigs were examined. Forty-eight pigs (12 wk of age, 43.2 ± 4.3 kg) were assigned to six treatments: thermoneutral conditions (21 ± 1.1 °C; 40% to 70% relative humidity) fed ad libitum with (TN+) or without supplement (TN−), heat stress (35 ± 1 °C; 20% to 40% relative humidity) fed ad libitum with (HS+) or without supplement (HS−), and thermoneutral conditions pair-fed to HS intake with (PFTN+) or without supplement (PFTN−). Supplementation (0.1 g/kg feed) began 2 d prior to the 3-d environmental treatment period. Body weights (BWs) and blood samples were collected on days −1 and 3. Rectal temperature (RT) and respiration rate (RR) were measured thrice daily and the feed intake (FI) was recorded daily. Intestinal sections were collected for histology. Pigs in HS conditions exhibited increased RT (~1.2 °C) and RR (~2.7-fold) compared with TN and PFTN groups (P < 0.01). HS+ animals had increased RR when compared with HS− animals (P < 0.02). Heat stress decreased FI compared with TN. HS and PFTN decreased (P < 0.05) average daily gain compared with TN. Supplement did not alter the BW gain. HS and PFTN decreased (P < 0.05) Gain:Feed compared with TN during environmental treatment. Supplementation with CAPS–SUC increased Gain:Feed by 0.12 (P < 0.05). Circulating glucose concentrations tended to decrease in CAPS–SUC vs. non-supplemented HS and PFTN animals (P ≤ 0.1). Circulating insulin concentrations as well as monocyte count increased in HS compared with PFTN (P < 0.04) but did not differ from TN and likely linked to altered FI. CAPS–SUC increased basophil count (P < 0.02), irrespective of environment. Ileal villus height tended to decrease during HS and PFTN compared with TN (P < 0.08), indicating an effect of intake. Overall, CAPS–SUC supplementation increased pig feed efficiency and may improve immune response.
