1. The study investigated the adsorption and removal of the herbicide Iodosulfuron from soils using activated carbon.
2. Soil samples were collected from different regions of Pakistan and tested for properties like pH, organic matter. Batch experiments examined the adsorption capacity of activated carbon for removing Iodosulfuron from soils.
3. Results found the adsorption and removal of Iodosulfuron depended on soil physicochemical properties like organic matter and pH. Soils with higher organic matter and lower pH showed greater adsorption. Activated carbon prepared from sawdust proved effective for removing the pesticide from soils in a cost-effective and environmentally-friendly way.

2013 ASPRS Track, Ozone Modeling for the Contiguous United States by Michael ...GIS in the Rockies
Ozone (O3) is a powerful oxidizer (e.g. reacting with oxygen). Ozone in the upper atmosphere is considered beneficial due to the ability of the compound to filter harmful UV rays generated from the sun. However, ground level concentrations of ozone influence animal and plant health. In animals, one symptom of ground level ozone is lung tissue damage resulting in respiratory complications. Excess ozone in plants can cause excessive water loss; thus, emulate drought conditions. Ozone simulates the stomata cell in plant leaves so that these cells do not function properly. That is the stomata cells do not close completely, resulting in excess water loss (Smith et al. 2008). Anthropogenic ozone can be created via internal combustion engines and coal fired power plants.
Collecting data from the Environmental Protection Agency (EPA) CASTnet site for the time periods 1990 to 2010 I use spatial interpolation techniques to create an ozone surface concentration for the contiguous United States.
Soil Carbon Sequestration Potential of Mangroves at Katunggan it IbajayASU-CHARRM
The Katunggan it Ibajay (KII) Eco Park is home to one of the most diverse mangrove forests in the Philippines. It is a 44.22 hectares protected park in the town of Ibajay in Aklan which boasts a total of 28 true species of mangroves or 80 percent out of the total 35 Philippine mangrove species. The forest is also a home to some species of birds and other wildlife like mud lobsters, fiddler crabs, mudskippers and other fauna. Recent studies have been conducted in the area which includes the identification of mollusk species, behaviours and activities of fiddler crabs. However, there is a lack of information on studies regarding Carbon storage and sequestration potential of mangrove species in KII.
Therefore, considering the vital role of mangrove species there is a need to conduct this study to provide a wide array of information about the total C-stock and sequestration potential of selected mangrove species in KII. Likewise, it will help local folks, LGU-officials and future researchers to increase their awareness to protect and preserve KII Eco-Park; to help reduce increasing negative impact of global warming in the environment.
Nitrogen deposition dose: Response relationships for habitats - Dr Chris FieldsIES / IAQM
Semi-natural habitats in Britain and, indeed, most highly populated world regions are threatened by aerial deposition of reactive nitrogen compounds, largely emitted from the processes of intensive agriculture, vehicles and power generation. We have been slow to understand the potential significance of the increased exposure and accumulation of nitrogen in the ecological system. Numerous research studies from varied habitats in different countries indicate that the composition and biodiversity of plant communities is adversely affected at even low levels of exposure and impacts may extend beyond the plant kingdom to other trophic levels such as butterflies and birds. Furthermore, the likelihood that negative change in habitats can be easily reversed is now being questioned due to the longevity of accumulated nitrogen in the ecosystem. This paper will discuss the main effects of nitrogen compounds and the nature of the dose response between nitrogen and ecological harm.
Theoretical study of heat transfer through a sun space filled with a porous m...Ahmed Al-Sammarraie
A theoretical study had been conducted to detect the effect of using a porous medium in sunspace to reduce heating load and overcoming coldness of winter in the cold regions. In this work, the heat transferred and stored in the storage wall was investigated. The mathematical model was unsteady, heat conduction equation with nonlinear boundary conditions was solved by using finite difference method and the solution technique of heat conduction had based on the Crank Nicholson method. The results had adopted on the aspect ratio (H/L=30), Darcy number (Da=10-3), porosity (φ=0.35) and particle to fluid thermal conductivity ratio (kp/kf=38.5). The results showed that using the porous medium had enhanced the heat transferred and stored in the storage wall. For the outside storage wall temperature, an increase of 19.7% was achieved by using the porous medium instead of the air, while it was 20.3% for the inside storage wall temperature.

Equilibrium and Kinetics Adsorption of Cadmium and Lead Ions from Aqueous Sol...theijes
Sourcing cheap adsorbents for the treatment of waste water is imperative for local environments. The adsorption of cadmium (Cd) and lead (Pb) from aqueous solution onto bamboo activated carbon prepared by chemical activation with ZnCl2 was investigated. The unwashed chemical activated bamboo carbon (UCABC) achieved up to 87.81% and 96.45% removal of Cd and Pb at pH-5 and 11, respectively. Removal equilibrium was attained within 1hr and 2.5hrs for Cd and Pb, respectively. The Cd and Pb adsorption increased with adsorbent dosage decrease while removal rate (%) increased with Cd and Pb concentration. Adsorption isotherm of Cd and Pb onto UCABC was determined and correlated with four isotherm models (Langmuir, Freundlich, Temkin and Hills). The equilibrium data fitted into Freundlich Cd (R2 = 0.9873, SSE = 0.045), Pb (R2 =0.9903, SSE = 0.051); Temkin Cd (R2 =0.9730, SSE = 0.052), Pb (R2 = 0.9079, SSE = 0.056); Hills Cd (R2 = 0.9961, SSE = 0.048), Pb (R2.= 0.9183, SSE = 0.053) and Langmuir Cd (R2 = 0.9653, SSE = 0.302), Pb (R2 = 0.9899, SSE = 0.136) isotherms. The Freundlich fitting showed isotherm adsorption capacity constants Kf = 7.843 and 5.098 (mg/g) for Cd and Pb, respectively. Furthermore, their adsorption kinetics correlated with the Pseudo-first order, Pseudo-second order and Intra-particle diffusion models and could be best described by the Pseudo-second order equation, suggesting chemisorptions as the limiting process. This study demonstrated that the UCABC can remove Cd2+ and Pb+ ions from aqueous solution to avert expensive commercial adsorbents
Retrieval & monitoring of atmospheric green house gases (gh gs) through remot...debasishagri
Climate change is one of the most important global environmental challenges of this century. Green House Gases (GHGs) are the main culprit for this problem. Though much of research has already been done about the distribution and sources (and sinks) of GHGs , still much more uncertainties are present. Currently, there are only a few satellite instruments in orbit which are able to measure atmospheric GHGs. The High Resolution Infrared Radiation Sounder (HIRS), the Atmospheric InfraRed Sounder (AIRS), and the Infrared Atmospheric Sounding Interferometer (IASI) perform measurements in the thermal infrared (TIR) spectral region. But these are having low sensitivity to lower troposphere. In contrast to this, the sensitivity of instruments measuring reflected solar radiation in the near-infrared (NIR)/shortwave infrared (SWIR) spectral region is much more constant (with height) and shows maximum values near the surface. At present, SCIAMACHY aboard ENVISAT launched in 2002 and TANSO (Thermal And Near infrared Sensor for carbon Observation) aboard GOSAT (Greenhouse gases Observing SATellite) launched in 2009 are the only orbiting instruments measuring in NIR region. Among all the algorithms the WFM-DOAS algorithm (Weighting Function Modified Differential Optical Absorption Spectroscopy) developed at the University of Bremen for the retrieval of trace gases from SCIAMACHY (Buchwitz et al.2005) is mostly used. This is based on the principle of differential detection of radiance in gaseous absorption channels with respect to neighboring atmospheric transparent spectral channels (not influenced by gas) to detect the conc. of desired gas. But scattering at aerosol and/or cloud particles remains a major source of uncertainty for SCIAMACHY XCO2 retrievals(Houweling 2005, Schneising 2008).Of late with the use of new merged fit window approach scientists have come up with less than 0.5 ppm error in the estimation of CO2 in the presence of thin cirrus cloud(Reuter, Buchwitz et. al. 2010). Schneising et. al.,2007,retrieved d three year’s column-averaged CO2 dry air mole fraction from the SCIAMACHY instrument using the retrieval algorithm WFM-DOAS version 1.0, with precision of about 2 ppm. In India a study was undertaken to compare the atmospheric methane concentration pattern from SCIAMACHY with the vegetation dynamics from SPOT, showed fairly good correlation of methane emission with the rice cultivation(Goroshi et. al.).
Thermal Performance Evaluation of a Direct Absorption Flat Plate Solar Collec...IOSR Journals
Abstract: Due to the growing demand of energy and lesser availability of fossil fuels there is a shift in our
energy concern towards renewable energy sources. There is no doubt that from all the available sources, solar
energy is the best option with its minimum environmental impact. Now a days different types of solar collectors
are widely used to harvest solar energy. It has been found that performance of the solar collector depends upon
the characteristics of the working fluid which is used to harvest solar energy in solar collector. In the present
work the effect of Al2O3-H2O based nanofluids on the direct absorption type solar collector has been
investigated experimentally. Nanofluids are the new class of the fluids with their improved properties over the
host/conventional fluids. The volume fraction of Al2O3 nanoparticles used is 0.005% and 0.05%. Efficiency of
the collector is calculated for different mass flow rates (60, 80, 100 ml/hr) of Al2O3-H2O based nanofluids. From
the results obtained by performing experiments, it has been found that collector efficiency increases about to 3-
4% when Al2O3-H2O nanofluids are used as compared to simple water. Comparison of the collector efficiency
for different mass flow rate and different concentrations are done. ASHRAE [4] standards were followed while
performing all the experiments.

Nitrogen-doped graphene-supported copper complex: a novel photocatalyst for C...Pawan Kumar
A copper(II) complex grafted to nitrogen-doped graphene (GrN700–CuC) was synthesized and then
demonstrated as an efficient photocatalyst for CO2 reduction into methanol under visible light irradiation
using a DMF/water mixture. The chemical and microstructural features of GrN700–CuC nanosheets were
studied by FTIR, XPS, XRD and HRTEM analyses. Owing to its truly heterogeneous nature, GrN700–CuC
could be easily recovered after the photocatalytic reaction and showed efficient recyclability for
subsequent runs.

Abstract:The level of natural radioactivity in soils and water of 74 samples collected from locations at Aden governorate south of Yemen was measured. Concentrations of radionuclides in soils and water samples were determined by gamma-ray spectrometer using a NaI (Tl) detector with specially designed shield. The mean activity level of the natural radionuclides 226Ra, 232Th and 40K is 30.41 ±2.4, 36.26 ±2.9 and 358.12±26.54 Bq kg-1, respectively. These values are well within values reported elsewhere in the country and in other countries with similar environments. The study also examined some radiation hazard indices. The mean values obtained are, 215±37Bq kg-1, 50.10±6 nGy h-1, 0.34mSv y-1, 0.30 and 0.34 for Radium Equivalent Activity (Raeq), Absorbed Dose Rates (D), Annual Effective Dose Rates (Eff Dose), External Hazard Index (Hex) and Internal Hazard Index (Hin) respectively. All the health hazard indices are well below their recommended limits. The paper recommends further studies to estimate internal and external doses from other suspected radiological sources to the population in Aden governorate.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

• About one or 2 percent of this energy is converted to wind
energy
5. WINDMILL DESIGN
A Windmill captures wind energy and then
uses a generator to convert it to electrical
energy.
The design of a windmill is an integral
part of how efficient it will be.

10. INTRODUCTION
Iodosulfuron is a vital herbicide used throughout the
world by virtue of its distinctive properties.
It is known as a post-emergent pesticide which poses
minimal crop damage.
Due to its extensive applications, it has obtained
immense communal interest
The adsorption capacity of herbicide Iodosulfuron was
deliberated through batch equilibrium experimentations
11. EXPERIMENTAL
SOIL SAMPLING AND PREPARATION
•Four to five kg soil samples were collected from six
distinct regions of Pakistan including Taxila, Attock and
Chakwal, Kotli and Karachi.
•Sample assortment was completed in February 2017 with
the mean temperature of 25℃ over all districts.
•Samples were gathered from definite points for each site
through random selection and then they were kept in
clean polythene bags.
12. ADSORPTION EXPERIMENT
All experiments were completed at laboratory at ambient
conditions 24-26°C.
The adsorption experiments were conducted using a
batch equilibrium technique in duplicate.
Acetone was used to prepare a stock solution of
Iodosulfuron.
UV-visible spectrophotometer was used to find out the
pesticide concentration
14. IODOSULFURON REMOVAL USING ACTIVATED
CARBON
Three
measurements
were taken for
each soil sample
collected from
different
districts:
Prior to addition
of activated
carbon.
After three
hours following
the addition of
activated
carbon.
After six hours
after the
addition of
activated
carbon.
15. RESULTS AND DISCUSSIONS
The physicochemical properties of soils evaluated included:
I. pH
II. Organic matter (OM)
III. Total carbon (TOC)
IV.Total nitrogen
V.Electrical conductivity
VI.Oil texture
16. RESULTS AND DISCUSSIONS
• The adsorption coefficient values varied broadly.
• Highest adsorption coefficient value was shown by s1 with highest organic
matter of 1.4% and lowest ph of 5.62. Values of R² (0.89-0.99) presented that
the adsorption outcomes were best fitted to linear adsorption model.
• The gibbs free energy values were found negative ranging from -17 kj mol-1
to -20 kj mol-1 proposing physio-sorption and exothermic collaboration
with particular soils.
• Statistical analysis of regression and correlation showed negative correlation
of soil ph and kd(ads) (r2= -0.91 and p= 0.011) and positive correlation with
organic matter (R2= 0.87).
• The highest removal percentages by s1 and s2 were 5 ppm (56%) and 7.5ppm
(47%) respectively.
