This document presents an introduction to a study that will examine the effect of nitrogen from organic versus inorganic fertilizers on the growth of sweet basil plants. The introduction discusses environmental contamination from nitrogen, and the importance of nitrogen for plant growth. The study aims to determine if there is a relationship between the source of nitrogen (organic vs inorganic fertilizer) and the growth of sweet basil plants. It is hypothesized that plants grown with organic fertilizer will grow better, as organic fertilizer will provide the appropriate amount of nitrogen needed. The methodology will involve measuring plant growth and nitrogen concentrations in soil treated with organic or inorganic fertilizers over the length of the experiment.

Nitrogen cycle PERIOD 4
The nitrogen cycle describes the natural processes by which nitrogen is converted between its various chemical forms and circulates between living organisms and the environment. Key processes include nitrogen fixation by bacteria, nitrification, ammonification, and denitrification. Humans impact the nitrogen cycle through activities like fossil fuel combustion and the widespread use of nitrogen-based fertilizers, which can introduce excess nitrogen into ecosystems and cause problems like eutrophication. More developed countries tend to introduce more nitrogen through industry and transportation, while less developed countries' impacts come more from agriculture and large populations.
Ana scifair research proposal 3 rise 2012. doc
The research proposal examines the effect of nitrogen from organic versus inorganic fertilizers on the growth of sweet basil plants. Thirty flower pots will be used, with 10 as a control group with regular soil, 10 with soil treated with organic fertilizer, and 10 with soil treated with inorganic fertilizer. The nitrogen levels will be measured in the soil and plant growth will be observed over 80 days. It is hypothesized that the plants grown with organic fertilizer soil will grow better due to a more moderate nitrogen level that avoids contamination of water supplies. The results may show that organic fertilizers provide sustainable nitrogen for plant growth while reducing nitrogen pollution of groundwater compared to inorganic fertilizers.
Our environment
This document discusses ecosystems and the impact of waste. It begins by defining environment and explaining how human activities produce biodegradable and non-biodegradable waste. It then defines ecosystems as areas containing living and non-living components that interact, including natural ecosystems like forests and artificial ones like gardens. Ecosystems have biotic components of producers, consumers, and decomposers, as well as abiotic components of air, water, and soil. The document concludes by asking questions about why some substances are biodegradable or non-biodegradable and their different impacts on the environment.
5. our environment
- The document lists various types of waste materials and categorizes them as biodegradable or non-biodegradable. Biodegradable materials like dead leaves and wooden materials can be broken down by microorganisms while non-biodegradable materials like plastic bottles and glass persist in the environment for a long time.
- It explains how adding waste to the environment can have different consequences depending on whether the materials are biodegradable or non-biodegradable. Biodegradable waste can enrich soil quality after decomposition but non-biodegradable waste may accumulate or release harmful substances.

Carbon Dioxide Injection
Carbon dioxide fertilization involves increasing carbon dioxide levels in greenhouses to improve plant growth and yields. Higher CO2 levels shift the activity of the enzyme rubisco to favor carbon fixation during photosynthesis. On average, yields increase 33% when CO2 is doubled. Commercial greenhouse operations commonly use natural gas, propane, or boiler flue gases to maintain CO2 levels between 1000 ppm for sunny conditions to 700 ppm for young plants or lower for cloudy days with more ventilation. Higher CO2 leads to increased sugar levels in fruits and vegetables, improving taste, growth rates, and time to flowering for some ornamental crops.
The Role Of Trees in the Bioremediation of Drinking Water
The document summarizes a research experiment in Sri Lanka that tested using trees for bioremediation of contaminated drinking water. Trees were planted densely around a drinking well to uptake contaminants through their roots. Native tree species formed a "root mat" in the buffer zone. Additional trees were used as wind breaks and crops were grown organically nearby. Water quality was monitored over time, showing reductions in nitrate, nitrite and other contaminants. The experiment demonstrated that establishing forests can help clean contaminated groundwater in a sustainable way.

The document then provides information on various science concepts related to greenhouses, greenhouse gases, ozone depletion, catalytic converters, biofertilizers, and photocatalysts.
The Nitrogen Cycle
The nitrogen cycle describes how nitrogen moves between the atmosphere, soil, plants, and animals. Nitrogen makes up most of the air but cannot be used by plants and animals in its atmospheric form. Bacteria play a key role in fixing nitrogen by converting it into forms that can be used by plants through processes like nitrification and assimilation. Humans have disrupted the natural nitrogen cycle through activities like fertilizer use that introduce excess nitrogen. Maintaining the balance of the nitrogen cycle is important for ecosystems and the environment.
Bioremediation & Phytoremediation
Bioremediation uses microorganisms such as bacteria, fungi, and plants to degrade environmental pollutants into non-toxic matter. It can be used to treat contaminated soil and groundwater in situ (where it is found) or ex situ by removing the contaminated material and treating it elsewhere. There are various types of bioremediation depending on the technique used such as bioaugmentation, biostimulation, and phytoremediation. It is an effective and often low-cost approach to cleanup, but can be difficult to control and may not reduce contaminant concentrations to regulatory levels.
Introduction to Applied Ecology
This document discusses various types of pollution including air, water, soil, noise and their causes and effects. It explains that air pollution is caused by the presence of man-made substances in the atmosphere that affect health and properties. Various air pollutants like SO2, NO and metals from industries have negative effects on plants, animals and humans, causing damage to respiratory systems, cancer and other health issues. Noise pollution is caused by unwanted sounds from vehicles and industries that affect people physically and mentally. The document also discusses ways to control different types of pollution through the use of cleaner fuels, industrial abatement technologies, and urban planning.

Intrinsic in Situ Bioremediation
This document discusses intrinsic in situ bioremediation. It explains that intrinsic bioremediation uses microorganisms already present in the environment to degrade contaminants, requiring no human intervention and being the cheapest form of bioremediation. Intrinsic bioremediation is tested at the lab and field levels before use to assess the microorganisms' ability to metabolize contaminants. Factors like moisture, pH, temperature, nutrients, electron acceptors, and toxin concentration affect the rate of intrinsic bioremediation. In situ bioremediation cleans up contaminated sites directly where pollution occurred, with options like biostimulation or bioaugmentation. It has advantages of being cost-effective with minimal exposure but
Effect of Agrochemicals on Environment
This document discusses the long-term effects of agrochemicals on the environment. It notes that while agrochemicals have increased food production, they have also negatively impacted the soil, water, air, and human health. The overuse of agrochemicals has killed beneficial soil organisms, increased nitrate levels in soil, polluted water sources, contributed to air pollution through pesticide drift, and posed health risks to farmers and rural communities through direct exposure. The ideal pesticide would only impact the target pest and break down harmlessly, but in reality no such chemical exists.

Inorganic and Organic Constituents and Contaminants of Biosolids: Implication...
This chapter discusses the inorganic and organic constituents and contaminants found in biosolids, which are byproducts of sewage treatment. Biosolids are composed of approximately 50% organic matter and 50% inorganic material. The organic fraction includes partially decomposed human waste and bacterial biomass, while the inorganic portion contains materials like soil, sediment, and silica. Biosolids can contain heavy metals like copper, zinc, cadmium, lead, nickel, chromium, and arsenic as well as synthetic organic compounds. When biosolids are applied to agricultural lands, the heavy metals are typically immobile in soils, though small amounts may leach with soluble organic matter or accumulate in plants.

The document discusses organic farming and the use of pesticides in agriculture. It provides information on Michelle Obama starting an organic garden at the White House to supply the first family with vegetables. It then describes what organic farming is and how it differs from conventional farming by avoiding the use of synthetic pesticides, fertilizers and GMOs. The document outlines the essential plant nutrients needed for growth and discusses the harmful effects of chemical fertilizers on the environment, soil and human health. It also details several health issues linked to pesticide exposure like cancer, neurological impairments and hormone disruption.
The Effects of Nitrogen Fertilizer on Plant Growth
Nitrogen is an essential element for plant growth and development however, due to environmental pollution, high nitrate concentrations accumulate in the edible parts of these leafy vegetables, particularly if excessive nitrogen fertilizer has been applied. The consumption of these foods can be harmful to human health, thus its critical to design an effective plan for applying nitrogen fertilizer to crops. This study used organic, inorganic, and liquid fertilizers to look at how they affected nitrate levels and lettuce growth. The healthy growth of trees is ensured by nitrogen fertilization. The studys objective was to determine how different nitrogen fertilization techniques affected a few chosen criteria. This analysis was thought to be a hazy representation of the demands of cherries produced in herbicide barren fields.

This document summarizes a study comparing the effects of natural and chemical fertilizers on plants and the environment. The study involved growing wheat crops in two fields, with one field using natural fertilizers like vermicompost and the other using chemical fertilizers like DAP and urea. Observations over 8 weeks found that plants grew faster with chemical fertilizers initially but that chemical fertilizers acidified the soil and reduced its fertility over time. In contrast, growth was slower with natural fertilizers but they maintained soil fertility levels. The conclusion was that farmers should minimize chemical fertilizer use and encourage natural alternatives to protect the environment and long-term soil health.
BSc Dissertation
This document presents a dissertation written by Stephen Owusu that investigates the effect of rates of biochar additions on soil nitrogen dynamics and yield of lettuce in a tropical soil amended with cow manure. The study characterized biochar and soil properties, conducted an incubation experiment with biochar and cow manure treatments, and measured their effects on soil nitrogen concentrations and lettuce yield over time. The results showed that biochar and cow manure additions significantly increased soil organic carbon, pH, and lettuce yield compared to the control. Biochar additions resulted in higher nitrate concentrations while cow manure led to higher ammonium. It is recommended that farmers use a combination of biochar and cow manure to maximize yields and soil properties.

Topic- Fertilizers.ppt
Dr. Satish S. Kola discusses fertilizers in his newsletter. He explains that inorganic fertilizers contain nitrogen, phosphorus, and potassium which are important for plant growth. Nitrogen helps plants grow, phosphorus encourages rooting and fruit production, and potassium aids disease resistance and hardiness. Inorganic fertilizers are produced via the Haber and Ostwald processes and contain compounds like ammonium nitrate and urea. While inorganic fertilizers increase land use efficiency, organic fertilizers are more environmentally friendly but less effective for crop production. Fertilizer research focuses on reducing environmental impacts and finding new, less expensive sources.
effect of organic matter in sustainable land use .docx
Organic matter plays a critical role in soil sustainability by improving soil physical, chemical, and biological properties. It provides nutrients for plants, improves water retention, enhances soil structure, and promotes microbial activity. Sustainable land management aims to use land resources in a way that meets human needs while maintaining the land's long-term productivity through practices like conservation tillage, crop rotation, and use of organic manures to increase soil organic matter over time. Organic matter benefits soil in many ways, including improving structure, drainage, moisture retention, nutrient availability, and biological activity through its role in supporting microorganisms.
Presentation 2 student 1
This document discusses the origins and principles of organic agriculture. It began in the early 20th century in Europe in response to problems with conventional agriculture like soil depletion. Organic farming focuses on regenerating soil through humus farming techniques like composting and crop rotation. The document also discusses the global presence of organic farmland and findings that most conventionally grown produce contains pesticide residues. It outlines the benefits of an organic lifestyle, including higher nutrition, supporting local economies and farmers, and environmental benefits. Finally, it proposes a 12-month plan to transition to a more organic home through changing cleaning products, food, clothing and other items.
Eco-Landscaping Guide - Northern Cook County, Illinois
The document provides guidance on establishing a natural lawn through eco-landscaping methods. It discusses determining the appropriate uses for different areas of the lawn and selecting grass varieties suited to site conditions. Key considerations include soil characteristics, climate, water needs, and diversity. The goal is to cultivate a healthy, low-maintenance ecosystem through organic practices that reduce chemical dependency and environmental impacts.
The Benefits of Using Organic Fertilizers
Plant growth is accelerated by organic fertilizers. This goal is accomplished through two methods, the most common of which is the addition that adds nutrients. The second way that different fertilizers work is to change the soil's water retention and aeration to increase its potency. Composts regularly provided, in shifting extents. There are numerous categories for organic fertilizers. They are categorized according to whether they supply a single nutrient; if so, they are referred to as "straight fertilizers." Two or more nutrients are provided by "Multinutrient fertilizers." Organic fertilizers and inorganic fertilizers are also sometimes used to describe fertilizers. The following section discusses the advantages of organic fertilizers and artificial fertilizers.

Organic and Synthetic Hydroponic Systems
Organic hydroponic systems have the potential to significantly increase food production while reducing environmental impacts. These systems can grow 7-10 times more food in the same space using 80-90% less water than traditional agriculture. Additionally, organic hydroponics reduces the need for pesticides and produces year-round in controlled environments. The document argues that widespread adoption of organic hydroponics, combined with innovations in renewable energy and the use of agricultural byproducts, could help address issues of food security and climate change.

Potential of ornamental plants for phytoremediation of heavy metals
The document discusses the potential use of ornamental plants for phytoremediation of heavy metals. Phytoremediation uses plants and their associated microorganisms to remove contaminants from the environment. It is a natural, low-cost process to remediate sites contaminated with heavy metals. Ornamental plants could accumulate heavy metals through their roots and leaves, converting contaminated land into landscapes while preventing metal entry into the food chain. Factors like plant species selection and soil properties influence metal uptake. Phytoremediation provides economic and environmental benefits but also has limitations from contaminant leaching and plant disposal.

In recent years, cultivation of leafy vegetables such as lettuce and spinach using hydroponic systems in closed plant factories under light-emitting diodes (LEDs) lamps is becoming popular. Unfortunately, these vegetables may accumulate high level of nitrate which pose serious human health implications, upon being consumed by consumers. Finding solutions to lower the nitrate content through environmental control is important for vegetable quality control. Therefore, strategies are leaning towards to minimize the nitrate accumulation in leafy vegetables for agricultural product security. The aim of this review is to understand the factors leading to nitrate accumulation in a closed plant factory, to study the factors affecting nutrient ions management in hydroponic system, to review the cultural measures that may lead to minimize the nitrate content in leafy vegetables under controlled environment. Genetic, agronomic (e.g. supply, composition, timing, and form of nitrogen fertilizer), and environmental factors (e.g. temperature, light quality, intensity and photoperiod, carbon dioxide concentration) can significantly impact the nitrate level in leafy vegetables. To produce high quality vegetables especially in low nitrate content, regulatory methods during cultivation including light quality and other aspect of nutrient solution, can Improve the value-added product.

Two mycobacteriophages were isolated from a soil sample collected in Gurabo, Puerto Rico. Following enrichment and plaque purification, two distinct phages (named Shockage and Zombage) were isolated based on differences in morphology and protein band patterns. Shockage had a distinct protein profile while Zombage and another initially isolated phage had nearly identical protein bands, indicating they were the same phage. Further DNA sequencing would help fully characterize these newly isolated phages and determine if they represent unique viruses. Overall, this experiment demonstrated a method for isolating new mycobacteriophages from environmental samples.

This document summarizes research on a two-component nanoparticle system that uses communication to amplify targeting of nanoparticles to tumors. The system consists of "signalling" nanoparticles that first target tumors and activate the coagulation cascade locally, and "receiving" nanoparticles that target areas of coagulation activation to deliver diagnostic or therapeutic agents. Two types of signalling nanoparticles are investigated - gold nanorods that activate coagulation when heated with near-infrared light, and engineered tissue factor proteins that activate coagulation upon binding to tumor receptors. Both are shown to induce localized fibrin deposition in tumors. Receiving nanoparticles containing imaging or drug payloads are then able to target the coagulated tumor sites for enhanced delivery.

This article discusses a study that surveyed patients with inflammatory bowel diseases like Crohn's disease and ulcerative colitis about their use of cannabis. The researchers hypothesized that cannabis works as an anti-inflammatory through receptors called endocannabinoids. The survey found that in most cases, patients reported cannabis helped relieve abdominal pain, diarrhea and reduced appetite. While cannabis has side effects, it improved quality of life for these patients and could be a viable treatment option.
Ss second
This research paper studied whether cannabidiol inhibits inflammatory hypermotility in mice. Researchers induced intestinal inflammation in mice using croton oil, then tested the effects of different doses of cannabidiol. They found that cannabidiol effectively reduced hypermotility when inflammation was present, and higher doses produced greater inhibition. The study concluded that cannabidiol can help normalize intestinal motility during inflammation.
Ss first
This article describes a study of 30 Crohn's disease patients who used cannabis as a treatment. Cannabis is known to have anti-inflammatory properties, and a symptom of Crohn's is bowel inflammation. The study found that 21 of the 30 patients experienced great improvement in their condition after using cannabis. The results show that cannabis treatment can reduce symptoms of Crohn's disease like bowel inflammation.

Galsulfase is a recombinant form of human N-acetylgalactosamine 4-sulfatase that was approved by the FDA in May 2005 for the treatment of mucopolysaccharidosis type VI (MPS-VI), a rare lysosomal storage disorder. MPS-VI is caused by a deficiency of N–acetylgalactosamine 4-sulfatase, which leads to the accumulation of dermatan sulfate. Clinical trials found that patients treated with galsulfase showed improvements in walking and stair-climbing ability compared to placebo. Galsulfase represents the first approved treatment for MPS-VI and provides an important new therapy for patients suffering from this rare disease.
Seminar yadilette rivera_amherst,mass_oct.18-1 copy
The Biology Honor Society will provide refreshments from 10:30-10:40 in room 106 MMM on Thursday. Yadilette Rivera, an alumna from Univ. of Massachusetts Amherst, will then give a seminar from 10:40-11:20 in room 106 MMM about the challenges of protein crystallography and graduate school.
Reflection on the third seminar
Yadilette's research focuses on treating lysosomal storage disorders, which cause bone abnormalities, through enzyme replacement therapy rather than bone marrow transplantation. Her treatment involves purifying proteins through crystallization and x-ray analysis to determine the replacement enzyme, then injecting patients weekly and monitoring their progress through tests, with some patients showing increased mobility based on walking and climbing tests. This research helps improve the lives of those suffering from these diseases and creates more awareness.

This document discusses incorporating unnatural amino acids into proteins to expand their functions. It describes how pyrrolysine is used as an orthogonal system to incorporate unnatural amino acids specified by an amber stop codon. Various unnatural amino acids containing alkene and norbornene functional groups were successfully incorporated into GFP and other proteins in E. coli and mammalian cells. These modified proteins could then be site-specifically labeled using bioorthogonal reactions like the thiol-ene and Diels-Alder reactions. This allows proteins to be labeled and studied in live cells with new functions.

This document describes a new method for site-specifically labeling proteins using genetically encoded norbornene and rapidly reactive tetrazine probes. Key points:
1) A norbornene-containing amino acid is genetically encoded in E. coli and mammalian cells using the pyrrolysyl tRNA synthetase system.
2) A series of tetrazine probes are developed that react rapidly and specifically with norbornene via an inverse electron demand Diels-Alder reaction.
3) The tetrazine-norbornene reaction is shown to be much faster than established bioorthogonal reactions, allowing specific labeling of proteins both in vitro and on mammalian cell surfaces.
Ad jessica torres seminar
Jessica Torres from North Carolina State University will give a seminar on incorporating unnatural amino acids into proteins. Unnatural amino acids allow the expression of proteins with new functions and enable a wide range of studies by using diverse functional groups beyond the 20 common amino acids. Examples include incorporating fluorescent and spectroscopic probes to study biological processes in live cells. The seminar will discuss how introducing unnatural amino acids into proteins, both in vitro and in vivo, is a promising technique that can provide insights into answering biomedical questions relevant to human health. Refreshments will be provided before the talk at 10:30am on Thursday September 20 in room MMM 106.
Second seminar reflection
An improved method of protein labeling uses unnatural amino acids inserted during protein synthesis, which do not interfere with the organism's natural systems. The unnatural amino acids are chosen for their similarity to natural amino acids but are distinct enough to avoid incorporation elsewhere. By adding a stop codon to the unnatural amino acid and inserting it into tRNA, only the desired protein will be labeled without affecting other proteins.

Rta is a key transcriptional activator that is required for reactivation of Kaposi's sarcoma-associated herpesvirus (KSHV) from latency. Rta stimulates DNA binding of the transcription factor RBP-Jk to KSHV promoter regions containing RBP-Jk binding sites. The interaction between Rta and RBP-Jk leads to recruitment of additional factors and transactivation of immediate early and delayed early genes, establishing the lytic replication cycle. Precise cis-elements including CANT repeats and [A/T]3 motifs that flank the RBP-Jk site contribute to the strength of Rta/RBP-Jk mediated transactivation. Understanding this molecular mechanism of
