This document presents a new method to characterize the hydrophobicity of nanoparticles using hydrophobic interaction chromatography (HIC). The objective is to quantify the relative hydrophobicity of metal nanoparticles with different surface functional groups. Gold nanoparticles were selected for testing, as they are easily detected and widely applied. The results showed that bare gold nanoparticles eluted in the phosphate buffer phase, indicating hydrophilicity, while PEG-functionalized gold nanoparticles eluted in the Triton phase, indicating greater hydrophobicity. This demonstrates that HIC can effectively determine the relative hydrophobicity of nanoparticles and how surface functionalization influences this property.

This document discusses using stable carbon isotope analysis to study phase transitions of soil carbonates during anaerobic biodegradation of petroleum hydrocarbons. It explains that carbonate minerals like calcite and dolomite are common in soils and can dissolve or form new minerals as conditions change. Stable carbon isotope ratios are measured to identify carbonate dissolution or addition. Laboratory experiments show that dissolving soil carbonates leads to re-formation of new carbonates during anaerobic degradation of hydrocarbons. This stable isotope method allows changes in the carbonate fraction of soil to be monitored.
Do sag problems
Using data provided about a river and wastewater effluent, the document discusses:
1) Calculating the dissolved oxygen concentration in the river two days after mixing with the effluent.
2) Determining the lowest dissolved oxygen concentration that will result from the waste discharge.
3) Solving practice problems using the Streeter-Phelps equation to model dissolved oxygen sag curves in streams impacted by biochemical oxygen demand from wastewater.
Wittig rearrangement
The document discusses the [2,3] Wittig rearrangement, a generalized sigmatropic rearrangement where a new pi bond and sigma bond are formed. It has stereospecificity and is used in organic synthesis. Examples given are in the synthesis of the EF-ring of Ciguatoxin 3C and the synthesis of C18 Cecropia Juvenile Hormone.
ACSSA Halide-Water Poster
This study assessed the i-TTM model for halide-water dimers by using it to investigate the infrared spectroscopy, thermodynamics, and dissociation of halide-water dimers. Centroid and path integral molecular dynamics simulations were performed on Cl−(H2O)2, Br−(H2O)2, and I−(H2O)2 clusters. The results showed that i-TTM can accurately predict thermodynamic and spectroscopic properties of these systems. Specifically, it was found that the dissociation enthalpy of the water dimer is reduced in the presence of halide ions, characterized by a weakening of the water-water interaction.

1) Reaeration is the natural process by which oxygen from the atmosphere transfers into bodies of water, counteracting oxygen depletion from biodegradation. It is dependent on factors like water velocity, depth, and turbulence.
2) The Streeter-Phelps equation models dissolved oxygen levels over distance in rivers and streams based on the rates of oxygen depletion from biodegradation and replenishment from reaeration.
3) Typical reaeration rates are highest in rapids and waterfalls and lowest in slow streams and large lakes. Higher water temperatures, stratification, and lower flow velocities reduce reaeration rates.

This document summarizes research examining the reduction of uranium (U) by iron (Fe) in the presence of titanium (Ti). The key findings are:
1) When U(VI) was reduced by magnetite nanoparticles (Fe3-xTixO4), titanium incorporation did not affect the ability of magnetite to reduce U(VI) to U(IV). However, with Ti-doped magnetite a U(IV) phase formed that lacked dioxo bridges between U atoms, distinct from uraninite.
2) Further experiments found U(IV) was stabilized as a mononuclear surface complex on Ti-doped magnetite. Co-precipitation of U(VI

Lithovit science
1) Lithovit is a foliar fertilizer consisting of calcium, magnesium, and carbonate supplemented with micro nutrients. It is produced by milling natural limestone to particles less than 10 micrometers.
2) When sprayed on leaves, lithovit particles enter the intercellular space and leaves surface. It acts as a fertilizer by supplying higher concentrations of carbon dioxide for photosynthesis, promoting plant growth and higher yields.
3) The mechanisms of lithovit action include releasing carbon dioxide in the intercellular space and on the leaf surface through chemical reactions between its carbonate groups and protons, water, and carbon dioxide present on the plant and environment.
Simple Thinking Makes Chemistry Metabolic and Interesting - A Review Article
First of all I give my love to all the students who reside in ‘Chemistry Phobia zone’. In this short article I shall try to share my simple thinking that I achieved during my last 16 years of journey in the route of Chemical Education. Before starting my journey it was a big encounter for me to change the conventional methods and makes chemistry easier and interesting to such student who belongs to Chemistry Paranoia Zone. I believe that students are just like flowers and it is our duty to nourish them properly as a gardener. In my infinitely small area of knowledge, I just try to innovate fourteen (14) teaching methodologies by including thirty four (34) completely new formulae in the chemistry world which were followed by different eminent writers in their books since last 90-95 years namely Sir G.Wilkinson, Prof. F. Albert Cotton, Prof. I.L.Finar, Prof. R.T. Morrison, Prof. R.N. Boyd, Prof. Solomons and Prof. Fryhle, Prof. J.G. Smith etc..

This study assessed the College chemistry teachers assessment of their usage of eleven pedagogical
methods in the National Commission for Colleges of Education (NCCE) Benchmark. The study also monitored
the influence of teachers qualification and gender on the usage of these methods. The study was carried out in
both Federal and State Colleges of Education in the five States in South-East zone of Nigeria. The sample for
the study comprises of all the sixty-one (61) chemistry teachers drawn from the seven colleges (state & federal)
in the five States. Three research questions and the three hypotheses guided this work. 55-item questionnaire
constructed by the researcher from the eleven pedagogical methods in the Benchmark was used as instrument
for data collection. This instrument was validated by experts in the field and reliability sought and after pilot
study and found to have 0.87 alpha value using Cronbach technique. Data collected were analyzed using means
and standard deviation for research questions and independent t-test for hypotheses at 0.05 level of confidence.
The result obtained showed that chemistry teachers adequately use only four methods, (demonstration,
experimental, discussion and lecture) during their classroom instructions. All other seven methods were not
adequately used. It was also discovered that teachers’ qualification and gender have no remarkable influence
on the usage of these methods. Recommendations for the usage of other methods were made.

This document provides a review of different techniques for segmenting brain MRI images to detect tumors. It compares the K-means and Fuzzy C-means clustering algorithms. K-means is an exclusive clustering algorithm that groups data points into distinct clusters, while Fuzzy C-means is an overlapping clustering algorithm that allows data points to belong to multiple clusters. The document finds that Fuzzy C-means requires more time for brain tumor detection compared to other methods like hierarchical clustering or K-means. It also reviews related work applying these clustering algorithms to segment brain MRI images.
M0111397100
This document analyzes the performance of various modulation schemes for achieving energy efficient communication over fading channels in wireless sensor networks. It finds that for long transmission distances, low-order modulations like BPSK are optimal due to their lower SNR requirements. However, as transmission distance decreases, higher-order modulations like 16-QAM and 64-QAM become more optimal since they can transmit more bits per symbol, outweighing their higher SNR needs. Simulations show lifetime extensions up to 550% are possible in short-range networks by using higher-order modulations instead of just BPSK. The optimal modulation depends on transmission distance and balancing the energy used by electronic components versus power amplifiers.
L011138596
This document provides a review of mobility management techniques in vehicular ad hoc networks (VANETs). It discusses three modes of communication in VANETs: vehicle-to-infrastructure (V2I), vehicle-to-vehicle (V2V), and hybrid vehicle (HV) communication. For each communication mode, different mobility management schemes are required due to their unique characteristics. The document also discusses mobility management challenges in VANETs and outlines some open research issues in improving mobility management for seamless communication in these dynamic networks.

It concludes that implementing encryption standards like RSA and AES can make transactions more secure and build trust in online banking.
Reaction paper
The document discusses several theories of first language acquisition:
1) Behaviourism views language as learned through stimulus-response and imitation, though it does not explain why all humans acquire language while other species do not.
2) The cognitive approach sees innate cognitive abilities as influencing language learning beyond just environmental factors. Piaget's stages of development also related to language acquisition.
3) The nativist approach, proposed by Chomsky, argues humans are born with an innate language acquisition device and universal grammar containing basic language structures. This explains consistent language acquisition across environments.
4) While each theory provides some insights, the document concludes that both innate and environmental factors likely influence language acquisition in a gradual process,
Study of abiotic factors across the brahmaputra belt in relation to its suita...
Abstract
A healthy ecosystem is a result of balanced interaction between biotic and abiotic factors. Water temperature, pH, DO, FCO2, TA, TH etc are the most important abiotic factors influencing the physico-chemical and biological events of water body (Rahman et al., 2008). All species have their own optimal range for these abiotic parameters. In relation to aquatic life, there maturation time is also dependent on these parameters. These factors have great influence on aquatic life (DuttaMunshi and DuttaMunshi, 1995). This paper deals with the observation of fluctuation of these abiotic factors across the Brahmaputra Belt and its relation with aquatic life, mostly fishes.

Chapter 10_Natural Methods of Wastewater Disposal.pdf
This document discusses natural methods of wastewater disposal, specifically stream self-purification. It describes how wastewater introduces organic matter that depletes dissolved oxygen in streams. Through natural processes like dilution, sedimentation, and bacterial oxidation, streams can recover and "purify" themselves. The document outlines four zones that occur as wastewater moves downstream: a degradation zone where dissolved oxygen is lowest; an active decomposition zone; a recovery zone; and a clean water zone where the stream is restored. It also presents the Streeter-Phelps equation that models the oxygen sag curve to analyze a stream's self-purification capacity.

Interrelationship between nutrients and chlorophyll-a in an urban stormwater ...Journal of Contemporary Urban Affairs
This study investigated ecological processes in an urban stormwater lake during its ice-covered period from November to mid-April. Data from two winter seasons showed chlorophyll-a levels under ice were 22% of open-water levels, indicating primary productivity still occurs. Nutrients like nitrogen and phosphorus were significantly higher under ice, likely from road and urban runoff. Under ice, total phosphorus levels correlated positively with chlorophyll-a when nutrient ratios were low, suggesting phosphorus controls algal growth. The results provide evidence of active nutrient cycles in stormwater lakes during winter, contrary to assumptions of dormancy under ice cover.Tranvik, Lars: The carbon fluxes at the land-ocean-atmosphere continuum
Tranvik, Lars: The carbon fluxes at the land-ocean-atmosphere continuumIntegrated Carbon Observation System (ICOS)
This document discusses carbon fluxes along the land-water continuum from land to sea. It summarizes previous literature on carbon cycling in inland waters like lakes and rivers. Some key points made in the document include:
- Inland waters cover a small percentage of the Earth's surface but play an important role in the global carbon cycle as sinks and sources of carbon.
- Dissolved organic carbon imported from surrounding landscapes makes up a large portion of the carbon in many inland waters.
- Carbon is transformed in inland waters through processes like flocculation, microbial mineralization, and photochemical mineralization.
- Sediment burial is an important fate of carbon in inland waters, with flocculation of dissolved organic carbon accountingTce
This document summarizes information about trichloroethylene (TCE) contamination of soil and groundwater. It discusses the physical and chemical properties of TCE that influence its behavior in the subsurface environment, including its density higher than water, low water solubility, and low soil organic carbon partitioning coefficient. These properties cause TCE to sink below the water table as dense non-aqueous phase liquid (DNAPL) pools and plumes, making it difficult to remove with conventional pump and treat methods. The document also reviews reaction mechanisms for TCE such as oxidation, reduction, and dehalohydrolysis that are relevant to remediation technologies.
Sect 13.2
The document summarizes key concepts about the water cycle, carbon cycle, and nitrogen cycle. It explains that the water cycle involves evaporation from bodies of water into the atmosphere, condensation of water vapor back into liquid water, and precipitation falling back to bodies of water. It also notes that human water usage can impact the amount of water available to evaporate. It describes how carbon and nitrogen cycle through the biosphere, atmosphere, soil and organisms, and how plants and animals rely on these elements to survive through photosynthesis and cellular processes.
Desalination_BrineWaste
This document summarizes a university student's investigation into desalination and its brine waste. It provides background on desalination processes like reverse osmosis and multi-stage flash distillation. These produce brine waste that is more concentrated than seawater and can harm coastal ecosystems if discharged untreated. The document examines environmental impacts like altered ecosystems and erosion from brine discharge. It then evaluates potential solutions like precipitating silver chloride from brine or electrolyzing sodium chloride to produce useful byproducts. The student concludes electrolysis of sodium chloride is the best option as the gases produced could be sold to offset costs while lowering brine chlorine levels and fossil fuel use.

It describes how carbon and nitrogen cycle through the biosphere, atmosphere, soil and organisms, and how plants and animals rely on these elements to survive through photosynthesis and cellular processes.
Desalination_BrineWaste
This document summarizes a university student's investigation into desalination and its brine waste. It provides background on desalination processes like reverse osmosis and multi-stage flash distillation. These produce brine waste that is more concentrated than seawater and can harm coastal ecosystems if discharged untreated. The document examines environmental impacts like altered ecosystems and erosion from brine discharge. It then evaluates potential solutions like precipitating silver chloride from brine or electrolyzing sodium chloride to produce useful byproducts. The student concludes electrolysis of sodium chloride is the best option as the gases produced could be sold to offset costs while lowering brine chlorine levels and fossil fuel use.

J. Sequeira Ocean Acidification SoA Review
This document summarizes research on ocean acidification and its effects. It discusses how increased CO2 absorption by oceans leads to acidification, affecting calcium carbonate availability and organisms that use it in shells and skeletons. While most research focuses on single species responses, one study found increased calcification in coccolithophores during winter when pH is lowest, contradicting hypotheses. Experts agree ocean acidification due to CO2 emissions will continue for centuries and exceed past rates, but have less consensus on specific biogeochemical issues.
Assessment of the Water Quality of Lake Sidi Boughaba (Ramsar Site 1980) Keni...
Sidi Boughaba Lake, part of a wetland complex of Morocco (Ramsar site in 1980) is located on
the Atlantic coast of northwestern Morocco, oriented NNE - SSW and located in an interdunal depression. The
existence of this body of water is due to the fact that the topographic surface is at a lower cost than that of the
piezometric surface of the coastal water table, rainwater and runoff water. The objective of this study is to
determine the physical and chemical characteristics of the waters of this lake. Thus, several water samples were
taken monthly in the period 2016-2017. Parameters such as: temperature, pH, electrical conductivity (EC),
chloride (Cl-
), turbidity (NTU), calcium (Ca2+) and magnesium (Mg2+). The results obtained show that the
distribution of the analyzed elements in Lake waters is quite variable between seasons, as well as between stations.
However, the analysis showed that the studied waters are very mineralized, with an EC between 7 g/l and 14.8
g/l. This mineralization is essentially evaporitic and is controlled by various processes, such as evaporation and
marine influence by aerosol.

2k21ene10 Eutrophication.pptx
Eutrophication is the process where a body of water becomes enriched with nutrients, often resulting in excessive plant growth and lack of oxygen. This summary discusses the causes and impacts of eutrophication in freshwater bodies. Nutrient pollution from sources like sewage, fertilizers, and livestock waste can cause cultural eutrophication. As nutrient levels rise, plant and algal growth increases, reducing water clarity and oxygen levels. Long term, a lake may transform from an oligotrophic to eutrophic state, changing the ecosystem. Eutrophication harms the environment and human uses of the water through impacts like algal blooms, loss of biodiversity, and health risks. Various methods can help control
16 8 12_c_watercycle
Human activity is affecting the water cycle through global warming, which intensifies the cycle and can lead to either flooding from excess water or drought from drying out of soils. Water quality and quantity are also impacted as human activities like pollution and overuse diminish the supply of clean, potable water available on Earth. Predicting and mitigating these effects on the global water cycle will help ensure a sustainable supply of freshwater for humans and ecosystems.
Healy 2012.pdf
This document summarizes a study that compared the nitrate removal rates, efficiencies, and potential for pollution swapping of different organic carbon media in laboratory denitrification bioreactors. The media tested included lodgepole pine woodchips, cardboard, lodgepole pine needles, barley straw, and a soil control. Results showed nitrate removal was consistently over 99% for all media. However, when considering pollution swapping through the production of other nitrogen species and leaching of contaminants, removal efficiencies ranged from 67% to 95%. Phosphorus releases from the bioreactors exceeded thresholds for eutrophication. Greenhouse gas emissions were dominated by carbon dioxide and methane, with little nitrous oxide. Compar

1. Natural forests can store significantly more carbon than previous estimates suggest, and the carbon stored in natural forests is an important component of national carbon accounts.
2. There are links between the carbon stock in a forest and carbon fluxes - a decreasing stock means the forest releases carbon to the atmosphere as a carbon source, while an increasing stock means the forest absorbs more carbon from the atmosphere as a carbon sink.
3. Deforestation and land use change account for around 17% of global anthropogenic greenhouse gas emissions according to the IPCC, making forests an important part of addressing climate change.
