...Almost all digital files can be used for steganography, but the formats of file that are more suitable are those with a high degree of redundancy. Redundancy can be defined as object bits that provide accuracy far greater than necessary for the object’s use and demonstration. The repetitive bits of an object are those bits that can be altered without the alteration being detected easily. Image and video files especially comply with this requirement, while research has also uncovered other file manuscripts that can be used for data hiding. This paper is mainly concentrating about image and video as carriers and their performance analysis based on its PSR and MSE...

...Administrative Ethics Paper Balancing the access to health data and privacy has caused a dramatic increase in the types of microdata, and this directs great expectations for health services research. Legislative attempts to protect individual privacy reduces the flow of health care data for research purposes and increases costs and delays, and this affects the quality of analysis. The journal provides a summary of the challenges that data confidentiality raises concerning health services research, the current methods used to ensure data security, and a description of one successful concept to balancing access and privacy. The analysis of these issues of access and privacy using a conceptual framework based on balancing the risk of re-identification with the utility associated with data analysis. The primary goal should be to generate released data that are as close to the maximum acceptable risk as possible. Health Insurance Portability and Accountability Act (HIPAA) and other privacy measures are considered having had the effect of lowering the ‘‘maximum acceptable risk’’ level and interpreting the data that is unable to be released. The journal discuss the levels of risk and utility associated with different types of data used in health services research and the ability to link data from multiple sources as well as current models of data sharing and their limitations. One particularly compelling approach is to establish a remote access ‘‘data enclave,’’ where statistical...

...for consumers. Eco friendly refers to having no harmful effects on the environment or its inhabitants. Green home believes that non synthetic environmentally safe pesticides promote a cleaner and safer home environment for families with children and pets. Our company creates pest control products that utilize organic compounds that are deadly to insects, but remain harmless to humans, animals, and plants (Safer Pest Control Project, 2010). Synthetic pest control kills more than just problematic insects in the garden. Chemical insecticides may bring harmful negative consequences to humans, animals and non-targeted organisms. Birds can be harmed after eating food that has been treated. Bird’s eggs have been affected by insecticides reducing the population. Insecticides can kill bees and reduce pollination which in turn reduces crop yields. Pesticides kill indiscriminately killing both pests and their natural predators. Once the predators are gone, the populations come back stronger and more pesticides and insecticides are used. This harms the soil, stealing its natural ingredients. These products are harmful if inhaled by humans, and can be harmful to humans and pets on contact. Green Home saw this as unacceptable. We set out to discover natural ingredients when combined at just the right amount will have the same helpful affects of the synthetic brands with harming pets, birds, children or other creatures. Green Home offers a wide variety of eco friendly pesticides including...

...Assessment of synthetic milk exposure to children of selected population in Uttar Pradesh, India Shuchi R. Bhatt1, Dr. Anita Singh2 and S. M. Bhatt3 (Abstract) The present study was carried out keeping in view the recently emerging concern of the adulteration of the natural milk with the synthetic milk. Synthetic milk is prepared by emulsifying vegetable oils with appropriate amount of detergent and urea. Samples of the natural milk with synthetic milk were analyzed for concentration of urea and detergent and their effect is assayed through survey in different population in Uttar Pradesh, India. Children’s had different range of intake of milk. Children of age group 1-5 years consumes about 50-250 mg of milk daily, while of age group 6-18 years of children consumes about 250-1000 ml milk/day and children’s of age group 19-22 consumes milk about 500-1000 ml milk /day. Addition of synthetic milk is on large scale in Meerut district of U.P. and mostly urea in such milk creating huge problem of headache, eyesight and diarrhea in children.

...CONCATENATIVE TEXT-TO-SPEECH SYNTHESIS OF TWO-SYLLABLE FILIPINO WORDS Lourdes T. Tupas, Rowena Cristina L. Guevara, Ph.D., and Melvin Co Digital Signal Processing Laboratory Department of Electrical and Electronics Engineering University of the Philippines, Diliman ABSTRACT In concatenative-based speech synthesizers, one of the most important problems is proper union of speech units to achieve an intelligible and natural-sounding synthetic speech. For that purpose, speech units need to be processed and concatenated so that discontinuities at concatenation points are minimized. Another possible solution to this is by using a larger speech unit to decrease the number of concatenation points. In this project, which utilized two-syllable Filipino words, the speech unit is syllable. Characterization of these Filipino words is done to differentiate words of the same spelling but of different meanings. This characterization took note of the pitch, duration of utterance of each syllable in the word, and the first three formant frequencies. A digital signal processing (DSP) block is also implemented. It accepts two-syllable text and outputs all the possible utterances of that word; this block is the text-to-speech synthesizer. A two-interval forced choice test was conducted to evaluate the level of naturalness of the synthesized speech. Words of the same spelling but of different meanings are distinguished using the prosody and intelligibility test. 1. INTRODUCTION ...

...DNA Mediated Charge Transport in p53 CHM 4390-U02 Rohit Vinod April 22, 2015 INTRODUCTION Human transcription factor p53 is considered to be an important and useful protein that plays a key role in cancer and tumor suppression. Many of the pathways in which p53 is utilized usually are apoptosis, cell deterioration also known as senescence, cell cycle arrest or DNA repair (Riley et. al, 2008). P53 also plays a role in glucose metabolism as a regulator of glycolytic and oxidative phosphorylation through positive and negative regulation of certain genes and the proteins that they encode for (Madan et. al, 2011). Usually if there are mutations in the genes that eventually translate into p53 then there are significant chance that tumors start to develop as seen in more than half of human cancers. In addition to such necessary roles, p53 also can sense oxidative stress and binds to redox-active DNA which often receives oxidative damage due to election migration through the DNA base stack. Many other sources of DNA oxidation can arise as a result of ionizing radiation, exogenous chemicals and even metabolic side products (Generaux et. al, 2010). DNA can be utilized in charge transport over distances of 100 base pairs or 34 nm in length (Augustyn et. al, 2013). The significance of the DNA oxidation and p53’s ability to sense oxidative stress is essential in understanding how DNA can be utilized in charge transport. In particular, redox activation in p53 occurs using DNA CT...

...The number of consumers purchasing organically grown produce has been on a slow but steady increase in recent years. Organic produce refers to fruits, vegetables, nuts, seeds, or grains that were grown using only natural means. Recent studies have shown that some chemicals are allowed to be used by federal guidelines and the produce is still deemed “organic”. To receive the freshest produce, gardening is the key, this will ensure that the food is truly organic and will save you money. Many consumers have made the choice to garden organically due to the concerns of synthetic chemicals on their food. Research studies have found that ingestion of synthetic chemicals (pesticides, herbicides, etc.) from conventionally farmed produce can increase the rates of cancer and other disorders. Some known synthetic chemicals also decrease the nutritional value in the food. Other consumers have swapped to organic gardening themselves due to the affects of modern agriculture on the environment. Organic gardeners grow plants according to a sustainable perspective in regards. This differs from the conventional method that emphasizes maximum profit. Conventional farming with it’s use of pesticides, herbicides, over farming, and other questionable practices have led to erosion of mineral quality of soil and the decline in quality of soil, air, water, and plants. Organic gardening can be simple. Even if you live in an apartment, you can actually grow fresh tomatoes and peppers in...

...Selangor, Malaysia Received: 20 February 2012; Revised: 12 February 2013, Accepted: 25 February 2013 Abstract: This paper is about modeling of chaotic systems via nearest neighbor approach. This approach holds the principle that future data can be predicted using past data information. Here, all the past data known as neighbors. There are various prediction models that have been developed through this approach. In this paper, the zeroth-order approximation method (ZOAM) and improved ZOAM, namely the k-nearest neighbor approximation (KNNAM) and weighted distance approximation method (WDAM) were used. In ZOAM, only one nearest neighbor is used to predict future data while KNNAM uses more than one nearest neighbor and WDAM add the distance element for prediction process. These models were used to predict one of the chaotic data, Logistic map. 3008 Logistic map data has been produced, in which the first 3000 data were used to train the model while the rest is used to test the performance of the model. Correlation coefficient and average absolute error are used to view the performance of the model. The prediction results by the three models are in excellent agreement with the real data. This shows that the nearest neighbor approach works well to predict the chaotic data. Unfortunately, increasing the number of nearest neighbors from ZOAM...

...Pomelo (Citrus maxima) Leaf as Fertilizer Renz Patrick B. Selga Submitted in partial fulfillment of the requirements In Research II The Special Science Class of Tayug National High School Tayug, Pangasinan July, 2013 Mrs. Revelyn Camacho Research Adviser CHAPTER I THE PROBLEM Background of the Study The pomelo tastes like a sweet, mild grapefruit, though the typical pomelo is much larger in size than the grapefruit. It has very little, or none, of the common grapefruit's bitterness, but the enveloping membranous material around the segments is bitter, considered inedible, and thus usually is discarded. Pomelos are usually grafted onto other citrus rootstocks, but can be grown from seed, provided the seeds are not allowed to dry out before planting. The seedlings take about eight years to start blooming and yielding fruit. The Pomelo leaf composed of different elements and compounds all of interconnected with the mineral content of its processing. The most important parts of the leaf in terms of of its chemical reaction are Minerals.

...using too much chemical pesticides and fertilizers. So people are looking for other new agricultures to instead of the old model such as the organic agriculture or organic food. Natural farming is based on the observation of nature and allowing it to do what it naturally does best. (Fukuoka 284) What organic food means? According to the Organic.org website, organic produce and other ingredients are grown without the use of pesticides, synthetic fertilizers, sewage sludge, genetically modified organisms, or ionizing radiation. Animals that produce meat, poultry, eggs, and dairy products do not take antibiotics or growth hormones (Organic.org). The chemical pesticides are the most of direct elements for which do harm to the environment. So organic food without these negative factors is benefit for environment. Then what does organic food effect environment? The first of all is organic food can prevent soil pollution. “Organic farms protect the environment by building soil organic matter and by mimicking natural systems rather than relying on synthetic fertilizers and pesticides.” (Organic Food) The development of organic food is originated from the development of organic farming. It applies developed biotechnology to organic farming. Organic food is based on the relationship between land, animals, human, bio system and the healthy agricultural production system. The basis is maintaining good condition of land. It can reflect by these aspects below. 1. Organic food can keep soil...
