Discouraging High Testosterone Levels

Discouraging High Testosterone Levels
In today's society, high testosterone levels are discouraged. In a world where we work in cubicles,
where violence gets you sent to prison, and where we are required to swallow our pride, to do what
we are told. Considering this, you could be led to believe that men are being poisoned intentionally.
A conspiracy, that guarantees we conform to their standards, throughout our lives.
Okay, before you dismiss me as a conspiracy theorist, take note that the Soviets were the first to add
fluoride to the drinking water, in prisons. They wanted to decrease testosterone levels, and to make
prisoners submissive. Considering testosterone is the driving force behind the courage of men, and I
seriously doubt the warden had any concern with dental health.
Now that you are ready to commit to a lifestyle that allows for the highest possible testosterone
levels, what do you do?
Detoxify First
Detoxifying sounds a lot worse than it really is. There are no enemas, or expensive juicer diets. You
just need to consume a form of sulfur, such as MSM, and zeolite. Both zeolite and MSM are fairly
inexpensive, and found readily at health and wellness stores.
Zeolite is formed when volcanic ash reacts with the surrounding rocks. This mineral has a regular,
porous framework that allows filtering, based on size. This "molecular sieve," catches toxic
substances, with its characteristic structure, and allows the impurities to be excreted, in your urine.

Volatile Aromatic Organic Compounds
1. Introduction The release of volatile aromatic organic compounds into the environment is a serious
problem as they distribute between the different phases in natural systems. Sediments can be
considered as a sink for volatile aromatic organic compounds because of their hydrophobic nature
and the resulting affinity to the sediment 's organic matter. Organic matter consists of soft carbon,
where portioning is the main sorption process and hard carbon, where pore filling mechanisms
dominate (Zhao et al., 2002; Chai et al., 2006). Consequently, sorption/desorption processes are the
most important factors that determine the fate of volatile aromatic organic compounds in the
environment. The extensive production and release of aromatic organic compounds has led to a
widespread contamination of soils and sediments with these pollutants throughout the world,
threatening drinking water resources, especially petroleum hydrocarbons as constituents of gasoline
such as Benzene, 1,2 dichlorobenzene, Toluene and m–xylene. It was proposed that sorption of the
sorbate molecules may cause deformation of flexible sorbent solids, such as natural organic matter
and organo–clays resulting in an entrapment of sorbed molecules during desorption (Weber et al.,
2002; Lu and Pignatello, 2004). Several researchers have tried to associate the maximum sorption
capacities of organic compounds with the sorbed amounts in the slow and very slow desorbing
domains (Van Heuvel et al., 2005; Van Heuvel and

Henry Ford Research Paper
Switching to Switchgrass
Henry Ford, in 1925, dubbed biofuels "the fuel of the future". Today, Mr. Ford's prediction is
coming true because biofuels are proving to be one of the most promising sources of alternative
energy. Biofuels are popular because they only release the CO2 that was collected during
photosynthesis. They solve many of the problems that fossil fuels present: greenhouse gases,
emissions, resource depletion, and foreign oil dependency. On the other hand, biofuel production
has drawbacks such as resource requirements, air and groundwater pollution, and usage of space.
The best material to invest in as a biofuel company is switchgrass lignocellulose, using the process

On the other hand, switchgrass combustion can release sulfur dioxide which can cause acid rain
(Qin et al.18). Switchgrass also has an incredible good EROEI of 5.4 (Kogel), and is a sustainable
crop that can be grown continuously. In terms of land, a farmer would have to plant 342 acres
producing 0.5 tons of dry mass per acre per day to meet the required revenue (Mitchell et al., 2008).
Also, switchgrass is feasible in drought, flood, and other harsh conditions. Overall, switchgrass
provides incredible economic and environmental benefits. Therefore, we recommend

Water Pollution
Additionally, once the zeolite molecular sieve columns are saturated with radium, the resulting solid
radioactive waste must be disposed of because the radium binds too tightly to the zeolite and cannot
be removed for future use in energy or heat production. Thus, this method still produces radioactive
waste, which has reached a total of one million tons in just one year.17 Because the solid waste
produced exceeds radioactive material soil application and landfill limits, this waste must be
disposed of in a costly, complicated manner that includes encasing the radioactive waste first in
glass, then in concrete, and finally burying it deep underground in regulated locations called
geological repositories.
Finally, a sizeable contributing factor to contamination of surface water is unpredicted and
accidental leaks and spills of PW before it is treated. PW is gathered and stored in holding ponds
before portions are either filtered off for reuse or for WW treatment or disposal. The holding ponds
are lined with polyethylene and polypropylene materials that may experience tears, rips, or holes
due to a variety of environmental and physical factors.18 Leakage and spills of transportation pipes
and connection valves have also been known to produce large discharges of waste into the
environment.18,19 In addition, transportation accidents have been known to release contaminated
water into the environment. As these are all unpredictable accidents, it is impossible to mitigate

Gerilla et al. (2007) discussed two different types of buildings which are wooden buildings and steel
reinforced buildings. They illustrated that wood type housing represents 77% of all residential
houses while steel reinforced concrete buildings represent 15% in Japan. They illustrated that carbon
emissions dominate other air pollutants as sulfur oxides, nitrogen oxides and suspended particular
matter by 93%. Carbon emissions of steel reinforced concrete buildings are greater than wooden

different types of steel reinforced columns taking into consideration the cost and carbon dioxide
emissions produced from these columns. They considered strength levels of concrete and steel.
Nevertheless, Park et al. (2012) did not consider construction phase,

A Brief Note On The Gas Mixture Of Hydrogen And Carbon...
1.2.3 Gasification and Syngas Syngas is a gas mixture of hydrogen and carbon monoxide, which are
products from gasfireing any hydrocarbon material such as coal at a high pressure and temperature,
30 bar and 1500 °K. The present of the oxygen is the primary difference between gasification and
combustion. When a feed gasfire, the oxygen or air is injected in small amount allowing part of the
feed to burn completely which supply the required heat and pressure, then, the heat will break down
the feed into synthesis gas (Higman & Burgt, 2003). This process consists of six main reactions:
Table 1: Gasification main reactions Reaction Process Chemical Formula Change in Enthalpy
Gasification with Oxygen C + ½ O2 → CO –3,922 Btu/lb C Combustion with Oxygen C + O2 →
CO2 –14,111 Btu/lb C Gasification with Carbon Dioxide C + CO2 → 2 CO 6,267 Btu/lb C
Gasification with Steam C + H2O → CO + H2 4,750 Btu/lb C Gasification with Hydrogen C + 2 H2
→ CH4 –2,672 Btu/lb C Water Gas Shift CO + H2O → CO2 + H2 –650 Btu/lb CO There are four
basic configurations for the gasification. These configurations describe the way oxygen introduced
to hydrocarbon feed since it will produce different characteristics for each one of them (Breault,
2015). The following is an explanation for each configuration: Table 2: The four basics

Devonian Rocks
Melbourne has a bedrock of Middle Paleozoic age which is included within the Devonian and
Silurian periods (354–441 million years prior). These rocks are overlain in wide zones which also
include much more youthful rocks, and were generally part of the Tertiary and Quaternary ages (2–
65 mya). Rocks of Early Silurian (441 mya) were discovered to be the most established within the
bedrock. Particular in the outcrops located in the north–east around Warrandyte (Anderson Creek
Formation), and on the west side of Melbourne more specifically the Maribyrnong Valley around
Keilor (Springfield Formation). Fossils found within these developments are very unique. Rocks
located east of Keilor and south of Warrandyte were discovered to be more youthful, with different
ages from Late Silurian (418 mya) in the Melbourne Formation (city region) to Early Devonian (384
mya) at the Humevale Formation (Lilydale).
These Paleozoic rocks are steeply plunging sandstones and siltstones, with a little event of limestone
at Lilydale – the Early Devonian Lilydale Limestone. The Silurian rocks were stored in profound
water, while the Devonian rocks, which are exceptionally fossiliferous, appear to have been stored
in shallower water. These Silurian and Devonian rocks were folded into a progression of anticlines

Water Is An Essential Part Of The Human Life
Water is an essential part of the human life. According to Bob Allen, "About 70 percent of the
human body is made up of water" (2007). This is a massive part of human livelihood and is
manifested by the amount of water consumed daily. Water has unlimited uses and is used for
hygiene and dietary consumption. Citizens often use it, but never thoroughly examine what they are
consuming. Many studies have been conducted to analyze contaminants that fill water and the
dangers of being unaware. The problem of water contamination is an issue that happens globally. It
happens in places like Haiti, Ethiopia, Flint, Michigan, and even Alabama. These are places that are
affected so severely that many people have died from the contamination. According to the United
Nations Development Programme, "Half of the world's hospital beds are filled with people suffering
from a water–related disease" (The Water Project). In Opelika, Alabama according to the Marler
Clark network, "At least 13 people in Lee County, Alabama have been [was] made ill in an E. coli
O157:H7 outbreak traced to Sportsplex and aquatic Center in Opelika Alabama" (E. coli in
Swimming Pools). This was contamination found in a swimming pool that directly affected the
people. Additionally, Samford University is susceptible to water contamination if the source water is

Zeolites are highly porous crystals with minute channels ranging from 0.3nm to 0.8nm in diameter.
Due to their definite crystalline structure and the fact that their pores are too small to contain
carbonaceous build–up, zeolites do not share the problems of silica– alumina gels.
Zeolites are able to exhibit shape–selective crystals i.e.. their active sites are specific to only a few
product molecules (the ones that will fit into the tiny pores).
An example of this is when the zeolite ZSM–5 is used to catalyse the synthesis of 1,4–
dimethylbenzine. When molecules of methylbenzene combine with methanol in the ZSM–5 catalyst,
only rod–shaped molecules 1,4–dimethylbenzene are released,
(these are the commercially desirable ones). The boomerang shaped molecules are unable to pass
through the catalysts pores and are therefore not released.
Until relatively recently, one of the large drawbacks with catalysts was the highly toxic by–products
which they became after use. This was because the catalysts were often corrosive acids with a high
toxicity level in liquid form.
Examples include hydrogen fluoride. Once these catalysts had been used this promoted great
problems in terms of disposal as these acids corrode disposal containers and are highly dangerous to
transport and handle.

These problems have been solved by a new type of catalyst. Solid acid catalysts, such as silica–
alumina gels and zeolites, hold their acidity internally

South Africa 's Location Of The Continent Of Africa
South Africa is a located at the very bottom of the continent of Africa. It is surrounded on three sides
by the Atlantic Ocean by the West and South and the Indian Ocean to the East. To the North it
boarders Namibia, Botswana, Zimbabwe, Mozambique, and Swaziland. One interesting thing is that
there is a landlocked, surrounded on all sides by land, country of Lesotho. This is evident by Map 1,
shown below, that shows South Africa in the red box and the darker brown country within South
Africa being Lesotho. Which still remains true today, Lesotho is still its own country with an
unsettled relationship with South Africa. Map 1: South Africa's location on Africa (South Africa,
2015) The country has a very long history from our great ancestors to the extremely wide variety of
wild and unique animals. However, this land has been under quite a bit of bloodshed and
insatiability. From its days of slave trade, British control and the bloody revolutions these people
have been through, it has shaped the country as a whole. The one thing that seems to have impacted
the development of the country has been the issue of disease and the mortality rate of woman and
children. One thing that could be done to greatly reduce these issues would be to invest more in the
sanitation of the available water resources. This issue has been in progress of being improved but is
lagging behind due to the decolonization of the country. During negotiations with the African

Catalytic Vapor Cracking
Recently, Park et al. published an elaborated review on the use of zeolites, mesoporous catalysts and
metal oxide catalysts for catalytic vapor cracking. Zeolites, due to their acidity and shape selective
catalysis, are reported to be the most effective catalysts for the production of deoxygenated liquid
fuel consisting of gasoline range aromatic hydrocarbons. The product composition of the upgraded
bio–oils varied with Si/Al ratio and the pore structure of the zeolites. Low organic product yields
and rapid deactivation of the catalysts are the drawbacks associated with zeolite catalysis. Recently,
Carlson et al. demonstrated that high catalyst to feed ratios and high heating rates attenuate the
catalyst deactivation despite improving organic product yields. Poor organic product yields (due to
secondary cracking reactions) and the deactivation of HZSM–5 catalysts can be attributed to their
high Brönsted acidity. The Brönsted acidity of the HZSM–5 catalysts can be attenuated, without
inhibiting the catalysts activity towards hydrocarbon reactions, by addition of transition metal ions
to the catalysts. Addition of transition metal ions like Co, Mo, Fe, Ni, Ga, etc. enhances the product
yields (by decreasing the number of Brönsted acid sites and therefore the secondary cracking
reactions) as well as the selectivity towards hydrocarbons. Addition of metal ions to the acidic
supports give catalysts bi–functional behavior, where acidic supports catalyze the formation of
olefins

Methanol: Ecologically Clean Fuel
In recent years increasing interest to methanol as an effective means to produce a ecologically clean
fuel, available and cheap raw materials for the synthesis of various hydrocarbons and products of
their processing. The most accessible and cheap raw material for the obtaining of CH3OH are
natural and associated gases, from which by Fischer–Tropta's method it is possible to obtain
hydrocarbons of different composition and structure. The formation of gasoline from methanol,
developed in the present time flows through the stage of formation of DME, which turns further into
the mixture of hydrocarbons consisting more than 50% of the valuable branched paraffins. Such
"methanol" fuel in their composition does not contain sulfur and nitrogen compounds and a minor
amount of aromatic compounds. Now, methanol increasingly became used as fuel and also as
additives to motor fuels (from 3 to 65%). Methanol increases the octane level of fuels and reduces
harmful emissions into the atmosphere. Based on the methanol it is possible to obtain alternative

The geopolymers like other molecular sieves are characterized using FTIR, SEM, EDS, XRD

ray fluorescence (XRF) or EDS to qualitatively and quantitatively identify the chemical composition
of principal components (López et al., 2014).
2.10 Adsorption isotherms
Adsorption isotherm is the relationship between amount of sorbate adsorbed by an adsorbent (solid)
and its equilibrium concentration at constant temperature (Theodore and Ricci, 2010). An
equilibrium is arrived at where a number of molecules arriving on the surface of an adsorbent equals
the number of molecules that are leaving (Thajeel, 2013). Equilibrium data is analyzed using
commonly known adsorption systems (Rahimi and Vadi, 2014). The earliest and simplest known
relationships describing the adsorption process are the Freundlich and the Langmuir isotherms
(Jalali et al., 2002). It is a versatile isotherm expression that can simulate both Langmuir and
Freundlich behaviors ( Sips, 1948; Nah et al., 1977). The Langmuir Freundlich isotherm can
describe both the Langmuir–type and Freundlich–type adsorption behavior and has been used for
modeling pH–dependent sorption effects of adsorption

Thermo-Chemical Storage Systems Essay
Thermochemical heat storage can be physical (sorptive) or chemical based on the material used. The
storage system which does not involve the production of new compound is called sorptive storage
while those which involve formation of new compound are called chemical storage. The successful
thermochemical storage system is sorptive storage system that works on utilizing the heat of
reaction enthalpy. Thermochemical storage has considerable benefits when compared to sensible
and the latent–heat thermal energy storage systems since it is easily controllable which prevents the
heat loss. The features of sorptive heat storage technology enables the implementation on a large
scale.

The features like increased storage capacity, decreased heat loss to the environment and flexibility
of heat storage over a wide range of temperatures makes the thermochemical storage system
superior to other storage systems.
The sorptive technology involves the absorption or adsorption of molecules through a reaction
thereby storing heat. This kind of sorption system results in the formation of physical bond between
the reaction pair, adsorbent (A) and adsorptive (B), which has a preferably high energy turnover.
The preferred reaction is mostly reversible in order to perform many charge and discharge cycles.
A + B ↔ AB + heat (see Figure 2) Figure 2: Schematic diagram of sorptive thermal energy storage
technology
When charging the compound, heat is applied to substance AB which dissociate into separate A and
B molecule/compound. The storage is facilitated by using certain inhibitors that control the reverse
reaction. To release heat, the A and B components are reacted by removal of inhibitors, ultimately
favoring the reaction, resulting in the formation of compound AB and releasing heat. During this
cyclic process, when the reaction between A and B is prevented, the heat which can be stored due to
chemical energy cannot be released. The adsorbent such as zeolite (see Figure 3) react with water
thereby act as a sorptive storage material where adsorption of water

Carbon Monoxide Pollution
Background Since the Industrial Revolution, there has been an increased presence of pollutants and
carcinogens in the environment, specif–ically in urban areas.1 The presence of airborne pollutants
can lead to an increase in allergic reactions and asthma rates. A common airborne pollutant is carbon
monoxide (CO), which is commonly found in diesel exhaust. It is an odorless gas produced from
me–thane and non–methane hydrocarbon oxidation.2 The toxic gas eliminates and takes the place of
oxygen in the form of carboxy–hemoglobin when it binds to hemoglobin in red blood cells. It also
affects the binding sites of heme groups, which complicates the transfer of oxygen to tissues.3 The
majority of deaths from carbon monoxide poisoning is brought on from car exhaust.4 Between the
years 1979 and 1988, 57% of deaths from carbon monoxide poi–soning were brought from car
exhaust. There tend to be higher rates of carbon monoxide poisoning from car exhaust in northern
regions, where temperatures are relatively low (Figure 1). 5
A way to approach the elimination of carbon monoxide from car exhaust is through the use of
organometallic catalysts. Through the use of a catalyst, a reaction can occur at a faster rate and at
lower activation energy. Said catalysts serve are of great commercial interest because they
essentially convert simple mole–cules into more complex ones.6 Unlike homogeneous catalysts,
heterogeneous catalysts are not in the same phase as how the reac–tion is occurring. Because of this,
the catalysts are considered to be cheaper and easier to obtain. It is also considered more envi–
ronmentally friendly to use.6–7
Selective heterogeneous catalysis can be performed in terms of oxidation and reduction. A typical
reduction reaction would re–quire an oxidation agent and the use of certain intermediates, just like
the catalytic reduction reaction for the dehydration of ethanol (Scheme 1). The reaction uses solid
acids, such as group A salts, as catalysts and said catalysts are heated in order to convert etha–nol to
ethylene. The heterogeneous reaction is known as an acid–catalyzed, or bulk–type (I) catalysis,
reaction. 8
Proof of Concept When it comes to eliminating toxic components of car exhaust, there

Heavy Metals And Its Effects
1. Introduction
Heavy metals and their salts (Cu, Zn, Hg, Pb, Co, Ni,) are widespread industrial pollutants. In the
waters they come from natural sources (rocks, the surface layers of soil and groundwater), the
wastewater of many industrial enterprises and rain (polluted with smoke emissions). Heavy metals,
as trace elements, are constantly encountered in natural waters and aquatic bodies depending on the
geochemical conditions.
Heavy metals are quite stable and cannot be destroyed. Entering the ponds, they are included in the
cycling of matter and subjected to various transformations. Inorganic compounds are rapidly
solubilized in water and transferred into poorly soluble hydroxides, carbonates, sulfides and
phosphates. Later, these insoluble products settle down and contaminate the bottom sediments.
Under the influence of living organisms (bacteria, fungi and others) mercury, tin, and arsenic
undergo methylation, becoming more toxic alkyl compound. Moreover, metals can be accumulated
in various organisms and incorporated in the food chain and cause poisoning.
This project focuses on the elimination of cobalt (II) metal ions from contaminated waters. Even
though Co (II) appears to be one of the essential elements to human body at low concentrations,
when cobalt is too concentrated; it may damage human body and may cause diseases such as asthma
and pneumonia1. Cobalt pollution may be caused by many alloys (super alloys in gas turbine of

Zeolite: The Next Hollywood Hero

What is a Zeolite?
Zeolites are naturally occurring porous minerals (that look like honeycomb in structure), and act like
tiny sponges. They can absorb and modify some harmful or unwanted elements from soil, water and
air. In the garden, they are well known for their ability to absorb unwanted heavy metals such as
lead and chromium. Interestingly, however, they can simultaneously absorb beneficial nutrients,
especially nitrogen and ammonia for soil, and ... Show more content on Helpwriting.net ...
Zeolite usually comes in a powder of granular form. When applying Zeolite, wear goggles to protect
the eyes, especially in windy weather. Please note that Zeolite readily absorbs ammonia which in
moderation is great for plants, but not for humans or animals. So please, always wear protective
gloves and eyewear around Zeolite.
Whether you are applying Zeolite to detoxify your soil, prevent leaching, or as a fertiliser boost, as a
rule, measure 250–500 grams of Zeolite per square metre of soil, together with fertiliser (if you feel
it's required), and water in well.
Zeolite can also be added to soil for potted plants before applying liquid fertiliser.
For your potting mix, add 5% of powdered Zeolite to the mix volume. For example, for 50kg of
zeolite per Mm3 = or approx 2.5kg of zeolite to a wheelbarrow full of potting mix (approx 50L
mix).
Even better – it's environmentally friendly too!
Worth mentioning again, not only does Zeolite detoxify your soil of harmful heavy metals, recharge
your plant fertiliser, prevent leaching, absorb odours AND act as a natural wetting agent, it is a
natural and cost effective alternative to chemicals in your garden.

What Are Zeolites?
What are zeolites?
According to (ref) the mineralogist community define a zeolite as a 'crystalline aluminosilicate, with
4–connected tetrahedral framework structure enclosing cavities occupied by large ions and water
molecules, both of which have considerable freedom in movement, permitting ion exchange and
dehydration'. This definition allows us to evaluate three components of a zeolite; a 4–connected
framework, counter balancing ions (also referred to as an extra framework ion) and an adsorbed
phase (in this case it is the water molecules within the structure.). Due to the diverse nature of the
zeolite family, they exist in many forms differing in structure and chemistry, therefore the definition
proposed above is restricted to certain types, aluminosilicates. Therefore, among minerals we will
familiarise ourselves with materials that carry zeolite properties but are not equivalent to the
definition proposed by mineralogists. One example would be the mineral wenkite; it has an
interrupted framework with only 3 oxygen's coordinated to the silicon atom, [O3–Si–OH].
Regardless of this difference and any other differences apparent in a zeolite mineral they still belong
to the zeolite family. Therefore, a more deviated definition which considers all zeolites is a zeolite is
an open framework composed of voids and pores where the movement of ions and molecules are not
limited.
Zeolite minerals share the general formula Mm+ . [Si1–xAlxO2] . nH2O where M is a metal cation,

Laundry Detergents As A Cleansing Agent
Introduction
Laundry detergents are a cleansing agent that is widely used in the industry to clean laundry. The
term "detergent" refers to mixtures of chemical compounds including Alkyl Sulphonates, which are
similar to soap but less affected by hard water (Farlex, 2014). Like soap, detergent increases the
ability of water to penetrate fabric and break down greases and dirt, however they are derived from
organic acids rather than fatty acids (Mifflin, 2005). A detergent is an ion or molecule that contains
both polar and nonpolar components. The polar component allows the detergent to dissolve in the
water, whereas the nonpolar component solubilizes greasy materials that are the usual target of the
cleaning process. Their molecules then surround the particles of grease and dirt, allowing them to be
carried away thus leaving your clothes clean. This EEI explores the performance of two different
laundry powders (Fab and Woolworths select Home brand) in different types of water; ranging from
soft to hard. These detergents were compared and analysed in different types of water from varying
locations to determine whether water hardness has an effect on the cleaning ability of detergents,
and whether products should be specifically formulated depending on the type of water.
Basic laundry powders
Laundry detergents such as Fab and Woolworths Select Home brand are composed of many
elements that each play important roles in the laundry process depending on the cleaning tasks

Reforming Process
At low temperature gasifiers a significant fraction of gas heating value is entrapped in methane and
other hydrocarbons. Reforming process is the alteration of hydrocarbon properties by rearranging it
.It upgrades the methanol and hydrogen production through steam reforming. In fact, the most
widely used method to produce hydrogen by steam reforming natural gas (Probstein, 1982).
Water Gas Shift Process
Shift reaction catalytically converts CO to H2 to through the water gas shift reaction for upgrading
the syngas.

thermodynamically but the kinetic are favoured by high temperature.
Pressure Swing Adsorption (PSA)
PSA is a technique which consists of four adsorber vessels, a compressor and H2S removal step.
This technique is best suited for hydrogen separation to obtain the pure H2 and the current

Iron (II) reacts with hydrogen peroxide to produce a hydroxyl radical and is oxidized to Iron (III).
Upon decomposition of a second hydrogen peroxide molecule, a superoxide radical is produced and
Iron (III) is reduced back to Iron (II). The contaminants are primarily destroyed by the hydroxide
radical, as it is highly reactive and oxidative (2). As iron precipitates above a pH of 3, the reaction
halts, as the iron ions are not available to participate in this reaction. This renders the use of Fenton's
Reagents impractical, as it would require large amounts of acid to lower the pH to the range required
for this reaction. It would also require large amounts of base to raise the pH to a permissible value
required for discharge. This introduces large costs, and makes the process cost prohibitive. In order
to overcome this limitation, it was found that iron–amended zeolites could be used to destroy
chemicals in water at nearly neutral pH (3).

Zeolites are materials composed of silica and alumina that contain micropores capable of adsorbing

This article studies a novel approach to improve membrane separation e– ciency { application of
external physical in uence (temperature di erence across the membrane). Oppositely directed
pressure and temperature gradients in membrane establish a molecular exchange ow when two

CO2 adsorption capacity is defined as a measure of an adsorbent's capability or potential to adsorb
CO2. It is expressed in terms of number of moles of CO2 that a unit mass of an adsorbent adsorbs
under equilibrium conditions. The CO2 adsorption isotherms for MCM–41–30, MCM–41–30–AP–
9–85–0.5 and MCM–41–30–TP–9–75–0.3 at 30 °C are presented in Figure 6(a). The CO2
adsorption isotherms for amine tethered samples exhibit a steep nonlinear concave shape due to the
strong interactions between carbon dioxide molecules and amine moieties. In contrast, MCM–41–30
exhibits a less steep isotherm indicating that pure silica interacts with CO2 only by physisorption
and hence lacks sufficient strong affinity towards CO2. Therefore, it is clear that the ... Show more
Amine efficiency provides a measure of the fraction of amine groups present in an adsorbent that
actively participate in adsorbing CO2 by chemisorption. It is reported that the theoretical maximum
value for amine efficiency that an ideal adsorbent should exhibit under dry CO2 adsorption
conditions is 0.5 (for PCO2 = 0.1–0.2) i.e., in the absence of significant physisorption at non–
functionalized sites. The amine efficiency values for MCM–41–30–AP–9 series and MCM–41–30–
TP–9 series are presented in Table 2, from which the variation in amine efficiency with respect to
amine loading can be noticed. From Table 2, it is evident that, as amine loading increases, at first
amine efficiency increases, then reaches a maximum at a critical value of amount of water added in
the reaction mixture and then finally drops off at water levels higher than the critical value for both
mono and tri aminosilane addition. The similar trend in amine efficiency is observed with respect to
increase in grafting temperature for constant amount of water, in case of both mono and tri amino
silane compounds. MCM–41–30–AP–9–85–0.5 sample exhibited the maximum amine efficiency of
~0.5, which is close to theoretical maximum value. This proves that MCM–41–30 serves as an ideal
support for amine tethering process, where the CO2 adsorption process is not hindered due to
transport/diffusion

Therefore, the water or irrigation management is practicing promise to reduce of CH4 emission
comparing to application of nitrogen use efficiency. Other studies have suggested that nitrogen
fertilizer have a minimal effect on CH4 emissions in flooded rice system (Dong et al. 2011: Xie et
al. 2010; Datta and Adhya 2014). In addition, result finding also agreed by Linquist et al. (2012) on
base of their metadata analysis showed that no effect of rate nitrogen or NUE applications on CH4
emission and also there was no relationship between DCD rate and CH4 reduction. Schimel (2000)
suggested that in flooded rice system the interaction between nitrogen fertilizers and the CH4
emission processes are complex, hence it is difficult to determine the underlying mechanisms
contributing to net effects on CH4 emission. CH4 and NH4+ are similar structure and substrate for
methane monooxigenase bind or react with NH4+ instead of CH4 (Schimel, 1998; Linquist et al.
2012). Hence, the availability NH4+ in soil inhibits the oxidation of CH4. The concentrations of
NH4+ in CF plots were observed simultaneous high until 38 DAT for all NUE amendments.
Therefore, it is by direct or indirect mechanisms the NH4+ inhibits CH4 consumption where is
thought occurring in the field. Contrary, the NH4+ and NO3− concentration in NCF plot were
already negligible at 11 DAT which it might transform by nitrification−denitrification or uptake by

The Effects Of Coal Ash On The Health Of Water Systems
Introduction Coal ash is a byproduct of burning coal in power plants and is composed mainly of
aluminum and silicon oxides. This ash is commonly stored away in dump sites, only to leach out
solutions of concentrated toxic heavy metals. Such issues are detrimental to the health of water
systems, posing both a human and environmental health risk. However, there are solutions to this
problem. Coal ash possesses unique chemical properties that allow for the remediation of other
environmental concerns, such as the treatment of soil polluted with heavy metals, the removal of
nutrients from wastewater, and the remediation of acid mine drainage in streams. Coal ash is known
to contain a number of different toxic metals, the exact content dependent upon the coal it is formed
from. Containing this potential pollution hazard is an expensive problem, as approximately 75% of
all ash generated is stored in landfills. In these sites, rainwater can leach out toxic metals including
mercury, arsenic, cadmium, chromium, molybdenum, lead and selenium. As over 500 million tons
of ash are produced each year, there's an increasing environmental health hazard to the surrounding
water systems of these landfills. Pollution can spread to municipal water systems and potentially
poison humans. As such, figuring out a better solution to deal with the unused coal ash is of
significant importance. Current uses of coal ash primarily include the formation of concrete due the
pozzolanic properties of coal

The Cook Inlet Basin : Location And Extent
Yetter, Drew J., Cook Inlet Basin
Location and Extent: The Cook Inlet Basin is located in the south central part of Alaska, and
stretches roughly 180 miles from the Gulf of Alaska to Anchorage. (Figure 1) This basin includes
Susitna and Copper River basins in the north and the Shelikov Straight to the southwest. The
watershed of this inlet covers around 100,000 km2 in southern Alaska, east of the Aleutian
Mountain Range, receiving water from four main tributaries, the Knit, Little Susitna, Susitna, and
Matanuska Rivers. The Cook Inlet is extremely important to the economy of Alaska as it provides a
navigable passage to the port of Anchorage in its northern end.
Stratigraphy: The Augustine–Seldovia arch, which is oriented east–west, transverse to the main
structural trend of the basin, separates the forearc basin into two depocenters. (ADNR 2006). The
northern depocenter in upper Cook Inlet is dominated by roughly 25,000 feet of Cenezoic strata. The
southern depocenter in lower Cook Inlet and Shelikof Strait contains a thinner Cenezoic section
superimposed on top of 36,000 feet of Mesozoic strata.
Tertiary deformation the Cook Inlet basin started between Eocene and early Oligocene time.
Deformation in the upper Cook Inlet is resulted in folds, faults, and eroded horst blocks. The
deformation was a result of transpressional forces. (Figure 3) As a result, adjacent grabens filled
with alluvial deposits and continued to deform until late Miocene to Holocene time.

What Can Replace Conventional Fossil Fuel?
What can replace conventional fossil fuel? Aviation industry has been booming over the couple of
years. This would mean that the usage of fossil fuels to power the airplanes is increasing annually.
Using rough calculations, it is shown that there are over 100, 000 flights flown everyday [1] . To get
a clearer picture on the usage of fossil fuels used, let's assume every usage of flight consumes
10,000 litres of jet fuel per day, so approximately 1 billion litres of fuel would be consumed. Over
the course of a year, the total usage of jet fuel would be roughly 100 billion litres. However, fossil
fuels are non–renewable resource that would run out one day. According to data shown below, there
are only 53.3 years before we run out of fossil fuels. Therefore, alternative fuels plays a big role in
turning the situation around on depending solely on fossil fuel to power an aircraft. There are
various alternative fuels on market, but algae oil and liquid fuel derived from gamma–valerolactone
(GVL) Source: BP Statistical Review of World Energy 2014) The main concern of finding an
alternative source for jet fuel is the feasibility of the fuel for large scale usage and also the economic
viability of the fuel. High cost price of the alternative fuel would only discourage companies to
adapt to the new alternative fuel as it would reduce the profit of the company. The efficiency of the
fuel is also a major factor that could help the persuasion of switch from conventional fossil fuel to

Advantages And Disadvantages Of Pervaporation
Observed first in 1919 by P.A. Kober, pervaporation, as the name delineates, incorporates
permeation of a component into the involved membrane matrix and the successive evaporation of
the permeated component into the vapour phase inside the membrane matrix. The vapour–liquid
interface is extant inside the membrane. The component from the liquid feed that permeates into the
membrane vaporizes into its corresponding vapour state in situ and gets selectively permeated to the
other side which depends on the difference between the transport rates of the components in the
liquid feed. Generally, the feed or the upstream side is at atmospheric pressure, while the permeate
or the downstream side is kept under vacuum so as to allow the selective evaporation of the target
component after permeation through the membrane (der Bruggen et al., 2015). The driving force is
the differences in partial pressures of the components on either side of the membrane. A thing of
note: the volatility difference between the feed components does not play any role whatsoever in
determining the selectivity of the components (Huang et al., 2008). The mechanism involved in
pervaporation is the solution–diffusion model.

developing mesothelioma. Zeolites, which is another type of fiber, may be linked to mesothelioma.
Furthermore, there has been evidence to suggest that mesothelioma may be linked to the SV40
virus. The SV40 virus was inside of the contaminated polio vaccines. People who took the polio
vaccine between 1955 and 1963 may have been exposed to this virus.
Myth: Mesothelioma Is A Contagious Form Of Cancer
Fact: The family members of a person with mesothelioma may also develop this condition. There
are several reasons family members may develop mesothelioma. For example, if the family
members worked together and were all exposed to asbestos, then they may develop this

Water Contamination Research Paper
Water contamination due to increased population and industrial activities is one of the most
challenging issues to the researchers, because it is continuously increasing threats to both human
health and the environment. With the rapid development of industries such as metal plating
facilities, mining operations, fertilizer industries, tanneries, batteries, paper industries and pesticides,
etc.,(1,2) heavy metals wastewaters are directly or indirectly discharged into the environment
increasingly, especially in developing countries. Unlike organic contaminants, heavy metals are not
biodegradable and tend to accumulate in living organisms. Many heavy metal ions are known to be
toxic or carcinogenic and cause high blood pressure, anemia, cancer, renal kidney disease, nervous

Owing to the standard limits of water, it generates a strong demand to improve the efficiency of
existing methods for removing Pb and Zn from the water. Many techniques have been reported for
the effective removal of hazardous heavy metals from aqueous solutions such as adsorption,
flocculation, coagulation, membrane filtration, electrochemical operations, solvent extraction, bio–
sorption, chemical precipitation, ion–exchange, as well as various other processes (6–7). However,
most of these techniques have several disadvantages such as production of secondary pollution, high
cost, high levels of energy and chemicals needed, and weak treatment operation at low metal
concentrations. (8–9). Adsorption is now recognized as an effective and economic method for heavy
metal wastewater treatment. The adsorption process offers flexibility in design and operation and in
many cases will produce high–quality treated
