Abstract: High performance concrete is very useful in modern construction process. A study was conducted investigate concrete strength parameter, like compressive, flexural and split tensile strengths, also durability parameters like acid attack, saturated water absorption and porosity of high-performance concrete (HPC) of M75 grade by replacement of 20%, 40%, and 60% of foundry sand by fine aggregate and 10%, 20%, 30% of flyash by cement with water binder ratio of 0.3. In order to get better workability of HPC, the super plasticiser of base sulphonated napthalene polymers are used. The HPC of M75 grade is designed as per ACI 211.4R-08 ‘Guide for selecting proportions for high strength concrete with Pozzolana portland cement and other cementitious materials'[1]. The mechanical properties, like compressive strength, split tensile strength, flexural strength characteristics of high-performance concrete were analyzed and durability studies, such as saturated water absorption, porosity were also calculated. The results demonstrate the strength and durability parameters of high-performance concrete with foundry sand and flyash. From the observation of results, the 40% replacement of foundry sand and 20% of flyash in addition of 3% of super plasticiser shows very high characteristics.

Subject: The Water and Environmental Reality of the Marshlands of Southern Iraq
Keywords: Hammar marsh, Water, Iraq
Abstract: The marshes in Iraq are a group of water bodies and are in the form of a triangle consisting of the cities of Al-Amara, Nasiriyah and Basra. The area of covered land can be filled with water at the time of the flood in the late winter, during the spring and the days of Chihod are reduced. The marshes are the most extensive ecosystem in the Middle East and West Asia with its freshwater bodies. The marshlands are an essential stopping point for migratory birds between Siberia and Africa as well as rare species of freshwater fish, wild animals, cows and buffaloes. The research included three axes as follows: the first axis is the development of the marshes which was concluded that the geological factor has a significant impact in the formation of the marshes through tectonic movements and geological times and frozen and warm ages. The second axis deals with the spatial and temporal variation of the water areas of Hawar Alhahmar and what has gone through in particular and the marshes of Iraq in general, from the environmental disasters that have caused high damage to it. The third axis presents the effect of variation in the water areas on the biodiversity of the marshes and their containment of aquatic plants of reeds and papyrus. There are floating plants with roots and others planted in the bottom and submerged plants are immersed in water, such as shamblin, zuhair duck and taurus. There are amphibious plants, such as golan, tail as well as animal niches of cows and buffaloes. Some conclusions were reached and some modest proposals were made to revive the marshes and make them a tourist attraction.

Subject: Biomedical Waste Management in Selected Hospitals and Clinics in Chennai
Keywords: Biomedical waste, Management, Segregation, Labeling, Disposal
Abstract: Biomedical waste though forms a small part of the total municipal waste generated, needs proper handling and management as it is capable of affecting the human as well as environment. It is produced as a result of the biological and medical activities involved in the diagnosis, prevention or treatment of diseases in healthcare facilities, also known as medical waste or clinical waste. 80% of these wastes are non-infectious while 20% is infectious and capable of affecting the human health. Hence, the Biomedical Waste Handling and Management Rules, 1998 was enacted by the Indian Government and amended to cater the emerging problems related to biomedical waste management. At present Biomedical Waste Management (BWM) Rules, 2016 is complied with which divides the waste into four broad categories based on colour coding, thereby improving the segregation of biomedical waste generated. This paper aims to analyze how far biomedical waste has been managed by hospitals and clinics in Chennai city as per the prescribed rules of BWM Rules, 2016. The study found that clinics have not given enough concern to biomedical waste management practices as per the BWM Rules, 2016. Although there are certain violations of the rules, there has been a significant difference after the enactment of the BWM Rules, 2016 on comparing with previous years.

Keywords: Crude glycerol, Dihydroxyacetone, glyceric acid, Gluconobacter oxydans, GCMS, FTIR
Abstract: The availability of petroleum sources in the near future is constrained, so nowadays renewable energy resources are largely focused. One of the most paramount renewable energy resources is the biodiesel. During the biodiesel engenderment, excess crude glycerol is engendered which contains methanol, free fatty acids and salt. The biodiesel engenderment results in 10% of glycerol as byproducts. The carbon content in the waste glycerol can be used to serve as a cheap carbon source for the production of high value chemicals, like dihydroxyacetone (DHA), succinic acid, ethanol, citric acid, propanediol, etc. Gluconobacter oxydans is a gram-negative rod or oval-shaped non-motile bacterium belonging to the family Acetobacter, capable of producing DHA. Under optimized condition of 10% (v/v) substrate concentration, 5% (v/v) inoculum at pH 6 and temperature 30oC, maximum yield of 81.64% (v/v) was obtained. Glyceric acid was produced as a byproduct during DHA production was confirmed by qualitative test, FTIR and GCMS analysis.

Subject: Housing Characteristics in Developing Countries as Important Determinants of Household Indoor Dampness and Mould
Keywords: Housing characteristics, Indoor dampness, Indoor mould, Southern India
Abstract: Housing characteristics are important determinants of indoor dampness and mould contamination, a risk factor known to be associated with an increased prevalence of respiratory symptoms. However, few efforts have been undertaken to assess the prevalence of dampness and mould in residential environments and finding its association with housing characteristics have not been explored in developing countries. Dampness was assessed in 710 households (408 rural and 302 urban) enrolled in a (The Tamil Nadu Air Pollution and Health Effects (TAPHE)) cohort study using a combination of questionnaires and quantitative measurements of moisture. Mould assessments were performed using standard gravitational settle plate technique. A subset of households was examined longitudinally for all the month in a year to find the seasonal impact on the mould prevalence. The prevalence of dampness and mould was examined in relation to a range of household level variables known to influence their distribution. The prevalence of the self-reported dampness was around 50% with moderate to severe levels of moisture percentage recorded in nearly 12-26% of households. Further, one or more species of mould were detected in 83.5% of households with Aspergillus being the most dominant (72.5%). Housing characteristics, such as location, poor housing construction, presence of animals, air conditioner, wall furnishing, high relative humidity and low wind velocity were found to be significantly associated with atleast one of the four selected mould genera as well as with one of the self-reported moisture indicators in the house. This study provides important baseline information for the prevalence of indoor dampness and mould and identified the housing characteristics that would influence the same in the households of southern India.

Abstract: In the past decades, the organic-inorganic halide perovskites (OHIP) based materials are the fast developing area in the field of material science. It has tremendous growth in the new generation of optoelectronic devices, such as solar cells, light emitting diode and photodetectors. It is inexpensive, easy to process and highly crystalline in nature. It also has the disadvantages that the compounds contain toxic lead ions in their inorganic part. To overcome the toxicity of lead containing material, we have synthesized strontium based organic-inorganic halide perovskites as the alternative material. The newly synthesized MASrCl3 and MASr(1-x) Sn(x)Cl3 has been characterized by x-ray diffraction, UV-Visible spectroscopy and photoluminescence for the analysis of crystalline, absorption and emission properties. This shows good absorption and emission properties for solar cells, LEDs, photodetector applications.

Abstract: Expansive soils exhibit low shear strength, consolidation settlement, swelling and shrinkage, etc., when in contact with water. In order to improve the engineering properties, the common method used is stabilization. In this project, experimentation is carried out to investigate the influence of additives, such as flyash, potassium chloride and coir on compressive strength, California bearing ratio and shear strength of the clay soil. The three additives are added and the tests are carried out by keeping flyash and potassium chloride proportions as constant (30% and 1%) and varying the proportion of coir (0.1%, 0.2%, 0.3% and 0.4%). Control sample with separate addition of flyash (30%), potassium chloride (1%) and a combination of potassium chloride and flyash (30% and 1%) are analyzed for index properties. In addition, coir is added and the engineering properties are also analyzed. The maximum dry density of flyash and potassium chloride added soil goes on increasing with addition of coir up to 0.3% by weight and then it gets decreased. But the optimum moisture content goes on decreasing by increasing the percentage of coir. The results shows improvement in california bearing ratio (CBR) value, compressive strength and shear strength of composite containing flyash, potassium chloride and coir (30% : 1% : 0.3%). Hence the addition of flyash, potassium chloride and coir can be effectively used for soil stabilization.

Abstract: The world’s current major electricity supply is produced from non-renewable energy sources and it won’t be available once it is fully used as it is depleting at a faster rate. Among the other renewable sources, solar energy is the most promising and inexhaustible source. Organic photovoltaic cells possess low manufacturing cost, flexibility, lightweight, portable and these are the major reasons for pushing the focus on organic solar cells. This report aims to discuss the potential use of an organic solar cell and tweaks made to increase its efficiency. A novel device architecture is developed and a slight modification in the active layer P3HT: PC61BM [poly(3-hexylthiophene):[6,6]-phenyl-c61-butyric acid methyl ester] weight ratio of (1:1.2) which will promote a better electron extraction and increase absorption in UV region. The GO/PEDOT: PSS is used as and hole transport layer (HTL) in the organic solar cell. Mostly organic solar cells can be easily degraded over a period of time. In this work, organic photovoltaic (OPV) cell was fabricated and checked for its stability. While reporting about its performance, the organic photovoltaic cells will play a vital role in the near future if the drawbacks are rectified.

Abstract: Oxidized multi-walled carbon nanotubes (o-MWCNT) incorporated pyrrole (PPy) and 4, 4’-diaminodiphenyl sulphone (DDS) polymer nanocomposite (PPy-co-DDS/o-MWCNT) was prepared through in situ chemical oxidative polymerization. The molecular structure of PPy-co-DDS/o-MWCNT nanocomposite was characterized by attenuated total reflectance infrared spectroscopy (ATR), diffuse reflective ultraviolet-visible spectroscopy (DRS UV-vis), Raman spectroscopy. The crystallographic profiles of nanocomposite were evaluated by x-ray diffraction analysis and thermal stability of adsorbent was examined by thermogravimetric analysis (TGA). The morphology of polymer nanocomposite adsorbent was studied by scanning electron microscope (SEM), energy dispersive x-ray analysis (EDX) and transmission electron microscope (TEM) with selective area electron diffraction pattern (SAED). The adsorption behaviour of PPyco-DDS/o-MWCNT nanocomposite showed high adsorption capacity (470 mg/g, 462 mg/g, 452 mg/g) towards corresponding heavy metal ions, such as Pb(II), Ni(II) and Cd(II) in aqueous solution. The PPy-co-DDS/o-MWCNT nanocomposite shows fast and spontaneous process for the removal of heavy metal ions adsorption and the kinetics followed a pseudo second order rate equation (R2»0.99). This result is perhaps due to the part of electrostatic attraction served as an oxidized MWCNT can be incorporated to the PPy-co-DDS structure to improve the removal of heavy metal ions of fabricated PPy-co-DDS/o-MWCNT copolymer nanocomposite.

Subject: Wetland Vegetation in Sludge Treatment Wetland : A Review
Keywords: Sludge treatment wetland, wetland vegetation, Phragmites australis
Abstract: The presence of wetland vegetation in sludge treatment wetland (STW) is one of the most important aspects of wetlands and their presence distinguishes constructed treatment wetlands from sludge drying bed. The wetland vegetation is one of the design components as it undergoes and support the pollutant removal mechanism and depending upon the characteristics of sludge applied in the sludge treatment wetland. The wetland vegetation used in sludge treatment wetland should be tolerant of soils, climatic conditions and seasonal cycles of inundation and drought. In this review, we consider wetland vegetation that have been used in such studies to play an important role in sludge treatment wetland that take part in enhancing sludge dewatering and stabilization. The decomposition of organic matter present in sludge and wastewater through absorption by plant and microbial conversion forms soil root-contaminant plant microbe system. The essential nutrients in sludge are converted into a useful end product through biological activity and make it safer for reuse and maintain soil fertility over long periods of time. Phragmites australis (common reed) species of the genera Typha (latifolia, angustifolia, domingensis, orientalis and glauca) and Scirpus (for example, lacustris, validus, californicus and acutus) spp. are used.
