Paper Title: Living Tower Construction as Fish Apartment with Glass Powder/PET Composite Basic Technology
ABSTRACT: Indonesia is the country with the 4th largest population in the world that is 225 million that every day produce waste both organic and inorganic. Total waste produced by Indonesia each year is 1.29 million tons, making Indonesia the second largest contributor of waste in the world. Inorganic waste can not decompose easily in the wild, plastic bottles just take 50-100 years to decompose while the glass bottle itself takes 1 million years. The duration of this decomposition process causes waste to contaminate only soil, water, or air if not treated properly. In addition, Indonesia has an area of ​​coral reefs reaching 50,875 square kilometers, or about 18% of the total world. In coral reefs live fish populations and other marine biota recorded 2,200 or 31% species of reef fish in the world are in Indonesian waters. However, illegal fishing and water pollution account for about 70% of dead and damaged coral reefs. As a result, species of marine biota that exist increasingly extinct. These two things are a big problem and should be resolved soon. The Tower of Life as a fish apartment made from glass and plastic bottle waste can overcome the amount of garbage that accumulates and provides a home for the existing marine fish population. The Tower of Life design has a unique shape, in which this life tower has 4 structural building poles around it made from glass powder/ PET composite technology arranged so as to suit marine conditions, and has a main pole as a gathering place for fish made from natural fibers As a place to attach fish eggs. Making Tower of Life is able to reduce the waste of glass bottles, and plastic bottles as much as 6.6 kg for every 1 unit produced. Moreover the Tower of Life can preserve the marine ecosystem by replacing the function of coral reefs so as to increase fish populations.

Paper Title: Corrugated Tabs for Enhanced Mixing of Supersonic Elliptic Jet

ABSTRACT: Experiments were carried out to study the effects of corrugated triangular tabs in controlling the mixing of Mach 1.5 elliptic jet. The aspect ratio of the nozzle at the exit is 3.37. The results of the corrugated tabs are compared with the simple triangular tabs and the effectiveness of both the tabs are found out by comparing with the uncontrolled jet. The blockage caused by the simple tab is 2.5% each for two tabs. Whereas, it is reduced to 2.2% for the corrugated tabs. The corrugations used in the present investigation were square. The experiments are carried out from NPR 3 to NPR 8 covering both favorable and adverse pressure gradients. The centerline pitot pressure decay for the jets, without control, with plain triangular tabs, and with corrugated triangular tabs, revealed that both the tabs are leading to a considerable mixing enhancement of the supersonic elliptic jet at all the pressure conditions studied. But unlike the axisymmetric jet, the CPDs for both the tabs overlaps especially in the nearfield region. The core length for the uncontrolled jet is around 5D whereas, it comes down to about 1D for both the tabs at NPR 3. Thus, about 80% reduction in core length is achieved by both simple and corrugated tabs at minor axis. Therefore, the performance of corrugated tabs to control the elliptic jet is similar to the simple triangular tabs. But, since the blockage offered by the corrugated tabs is lesser, it is advantageous from thrust loss point of view.

Paper Title: Insight Into The Biochemical, Kinetic And Spectroscopic Characterization Of Garlic (Allium Sativum) Phytocystatin: Implication For Cardiovascular Disease

ABSTRACT: Phytocystatins are cysteine proteinase inhibitors present in plants. They play crucial role in maintaining protease-anti protease balance and are involved in various endogenous processes. Thus, they are suitable and convenient targets for genetic engineering which makes their isolation and characterisation from different sources the need of the hour. In the present study a phytocystatin has been isolated from garlic (Allium sativum) by a simple two-step process using ammonium sulphate fractionation and gel filtration chromatography on Sephacryl S-100HR with a fold purification of 152.6 and yield 48.9 %. A single band on native gel electrophoresis confirms the homogeneity of the purified inhibitor. The molecular weight of the purified inhibitor was found to be 12.5 kDa as determined by SDS-PAGE and gel filtration chromatography. The garlic phytocystatin was found to be stable under broad range of pH (6-8) and temperature (30°C-60°C). Kinetic studies suggests that garlic phytocystatins are reversible and non-competitive inhibitors having highest affinity for papain followed by ficin and bromelain. UV and fluorescence spectroscopy revealed significant conformational change upon garlic phytocystatin-papain complex formation. Secondary structure analysis was performed using CD and FTIR. Garlic phytocystatin possesses 33.9 % alpha-helical content as assessed by CD spectroscopy.

Paper Title: A novel approach for quality maintenance and shelf life extension of fresh-cut Kajari melon: Effect of treatments with honey and soy protein isolate

ABSTRACT: Effect of treatments with different concentrations of honey (0 mL/L of water, 50 mL/L of water, 100 mL/L of water, 150 mL/L of water) followed by coating with soy protein isolate (50 g/L of water) on fresh-cut Kajari melons was investigated. Effect of honey separately without soy protein isolate coating was also investigated. The treatments were given prior to packing the samples in polypropylene trays and stored at 4 C for sensory and overall shelf life studies. A total of eight combinations of samples with three replicates each were analyzed for various quality attributes throughout the storage life. Highest weight loss occurred in untreated melon samples. Sample treated with 150 mL honey/L of water þ50 g SPI/L of water maintained highest total soluble solids throughout the storage. Sensory scores below 5 were given to control sample after day 8 of storage. Samples treated with honey (150 mL/L of water) showed better results in terms of most of the sensory characteristics. Ripening index decreased remarkably over the storage period with control sample reaching lowest values in comparison to treated samples. Total plate count of 9.63 log colony forming units per gram (CFU/g) for control sample and counts of less than 5 log CFU/g for treated samples were observed at the end of the storage.

Paper Title: Association of Sedentary Behaviour and Mental Health among Young Adults: A Cross-Sectional Study

ABSTRACT: Sedentary behaviour contributes to adverse physical health outcomes in youth. Although evidence for the relationship between sedentary behaviour and mental health outcomes is emerging, little is known regarding risk of psychological distress and low self-esteem. The purpose of this study was to investigate the association of sedentary behaviour with psychological distress and self-esteem in a well-characterised young adult population after controlling for a wide range of potential confounders. We adopted a cross-sectional study design. A sample of 352 participants, 208 (59.1%) females and 144 (40.9%) males responded to a survey. Participants were recruited from University Tunku Abdul Rahman, Malaysia. Sedentary behaviour of the participants was determined by Sedentary Behaviour Questionnaire. Kessler Psychological Distress Scale and Rosenberg Self-Esteem Scale were used to measure psychological distress and global self-esteem respectively. Analysis of sedentary behaviour demonstrated that participants have high sedentary times. The highest sedentary behaviour engaged by the participants was doing paperwork or computer work, followed by sitting, listening to music and sitting and talk on a phone. Participants spent least time playing musical instruments. Multi regression analysis was performed to determine the level of significance. Sedentary behaviour showed a statistically significant association with psychological distress and self-esteem. Sedentary behaviour can lead to mental health problems in young adults. These findings have a number of important implications for policy and practice. They highlight the need to ensure that young people have appropriate and timely access to evidence based services and interventions across the continuum. Further high-quality longitudinal or interventional research is needed to confirm findings and determine the direction of these relationships.

Paper Title: Role of Anthropogenic Canopy gaps on Natural Regeneration Pattern of Monospecific Ceriops tagal in Rakawa Lagoon, Sri Lanka

ABSTRACT: Mangroves are distinctly dominated in tropical and subtropical areas as special kind of trees, palms, shrubs, vines and ferns. Ceriops tagal is one kind of mangrove species which shows monospecific distribution in Rakawa lagoon in Sri Lanka. There are certain factors which influence the natural regeneration pattern of Ceriops tagal. Light intensity is one of the factors which penetrates through canopy gaps and regulates the growth of seed, seedling and sapling and these canopy gaps are resulted mainly due to anthropogenic canopy eradication. However, the studies on the influence of man-made canopy gaps on natural regeneration pattern of mangroves in Sri Lanka are limited, hence the current study was carried out in Rakawa Lagoon in July 2014 to estimate the regeneration pattern of Ceriops tagal by the means of mean seedling, sapling density and live, dead seed densities in open canopy sites with regard to closed canopy sites and further, to compare the mean density values of Seedling plus sapling obtained in July 2013 to get the overall knowledge on the effect of canopy gap for continuous regeneration pattern of Ceriops tagal. Consequently mean density of seedling plus sapling were taken as regeneration class 1 and height of seedlings and saplings and the number of live and dead seeds were documented from randomly selected three homogenous plots ,(4m2 x 3) from open canopy sites and three homogenous plots (4m2 x 3) from closed canopy sites. Two –Sample T- test and Paired T-test of “MINITAB 16 software” were used to analyze and compare the data. Mean density of regeneration class 1 in open canopy sites was significantly higher p=0.02 (p<0.05) than closed canopy sites. Hence canopy gaps play major role in enhancing the natural regeneration and increasing the survivability of Ceriops tagal species. This study is being continued further to validate this statement.

Paper Title: The influence of climate change, water and energy in ethnic issues: The case of Mille Lacs Lake in Aitkin County, Minnesota.

ABSTRACT: Aitkin County is a very sparsely populated county, even though it is only a 2-hour drive from the Twin Cities. Aitkin County faces similar issues with other rural counties. The issues that Aitkin County faces might not be visible by only looking at the demographics and economic statistics. The county faces issues regarding the relationship between White Americans and Native American Tribes. The following chapters on Climate Change, Water and Energy will analyze potential consequences of these three factors on the issues between White American and Native Americans and also the implications of climate change and water issues on the economy in Aitkin County. Aitkin County does not have a diversified economy, therefore negative impacts on tourism and recreation can have significant impacts on the economic status of Aitkin County residents. The case Minnesota v. Mille Lacs Band of Chippewa Indians reflects this conflict very clearly. In this case, the Chippewa Indians claimed that they still had certain fishing, hunting and gathering rights on lands that were ceded to the Federal Government in 1837.This paper will further analyze this case and examine its implication for further land use issues in Northern America. This paper also shows, that it is very difficult.

Paper Title: Preliminary Investigation of Nutritive Potential of Umucass 36 Cassava Root Meal As Substitute for Maize In Broiler Diets

ABSTRACT: The foundation for good health and human development is rooted in the capacity of a nation to adequately provide good quality food in appropriate quantity and at the right time to its own people. The issue of hunger and malnutrition are central in the economic crises that have remained the lots of African countries. Communal and or political clashes, cattle rustling, insurgencies, desert encroachment, lack of fund, unabated population increase and unpredictable climatic conditions are some of the factors militating against adequate supply of animal protein in many of the African countries. It is evident that the rearing of small animals and or poultry which are prolific is now an imperative.
The development of poultry, micro livestock and wildlife are strategic options that we must consider for food security attainment and poverty reduction in our nation and the entire African continent. The need for alternative energy and protein supply feedstuffs has become very important today because of the increasing cost of conventional feed ingredients which has made the poultry products become too exorbitant and unaffordable for majority of the African populace. In order to stem this tide, cheap, easily available unconventional protein and energy resources need be investigated, and where found appropriate, should be used to mitigate the cost of producing animal feed.

Paper Title: Lighting For The Aging Eyes

ABSTRACT: Lighting allows users to accomplish their tasks, feel safe and understand the surrounding environment. Therefore, it is an inseparable component of buildings. Building codes, energy standards and regulations determine the required illuminances to provide visual comfort. However, the existing requirements are constituted considering healthy eyes only. Different visual comfort requirements for people with visual disabilities, in particular for elderly people, are not clear. In fact, the illuminance requirements show great difference for elderly people. For instance, an average 60 years old eye requires three times more illuminance than an average 20 years old eye. Therefore, a lighting design that complies with the regulations may not satisfy elderly users’ needs.
The world’s older population continues to grow remarkably. The increasing share of population of older people requires increase of awareness. In this study, technical lighting information has been offered to obtain visual comfort in living spaces occupied by elderly. Such information is critical for lighting design yet not sufficiently covered in literature. For that reason within this study, different visual requirements of each space type are emphasized to promote accessible design.

Paper Title: Binary Luminescence Thermometry Probe Based on Mn4+ and Ho3+ Activated Phosphors

ABSTRACT: Temperature is by far the most commonly measured physical quantity; sensors of temperature account for 80% of all sensors worldwide with market of USD 5.13 Billion in 2016. Temperature sensors are used across a broad spectrum of human activities, such as in medicine, home appliances, meteorology, agriculture, and industrial and military contexts, to mention some of the most significant areas. Among emerging optical thermometry methods, luminescence thermometry has gain the most attention because of the sensitivity of luminescence on temperature and the ease with which luminescence can be detected in comparison to other optical signals.
Here, we aimed to develop the high-sensitivity luminescence thermometry probe which can utilize the ratio of two spectrally distinct emissions from two luminescence centers, one center whose emission intensity rapidly quenches with temperature (Mn4+) and one whose luminescence is insensitive to temperature changes (Ho3+) over the temperature range of interest (10 – 80°C). To achieve this goal, we have prepared Mg2TiO4:1%Mn4+ and Y2O3:1.5%Ho3+ by Pechini and Polymer complex solution methods, respectively. Luminescence emissions were measured by 465nm excitation from 450W Xenon lamp on Fluorolog-3 Model FL3-221 spectrofluorometer system (Horiba Jobin-Yvon), and the luminescence ratio is calculated to obtain the calibration curve. To test thermographic performance of the newly developed probe, an uncertainty analyses is conducted and repeatability measurements were performed.
