The surface soil moisture content (SSMC) is of great importance to the discipline of hydrology as well as to the other relevant studies and applications. Pioneer studies have pointed out that the most promising technique to retrieve SSMC regarding to accuracy and cost-effective belongs to the micro-wave remote sensing. By means of field observed SSMC dataset collected from the Yihe watershed located on the Linyi district, Shangdong province, China, we analyzed and validated the daily AMER-E SSMC products for the year of 2006 with the focus to examine the products quality of AMER-E SSMC for further studies by using the products. The results suggested that the temporal variation trend of AMER-E remotely sensed SSMC is reasonably consistent to the field observed, but is systematic lower than the ground truth in value in the whole year. The correspondence of AMSR-E SSMC product is significant enough compared with the field observed for the whole year except of the month of July and August.

Data Preparation for Assessing Impact of Climate Change on Groundwater RechargeAM Publications
Climate change is a change in the statistical properties of the climate system when considered over long
periods of time. It significantly affects the various components of hydrological cycle like temperature, precipitation,
evapotranspiration and infiltration. All these components together affect the rate of groundwater recharge. So
understanding the effects of climate change on groundwater recharge is the need of time for the management of
groundwater resources. This paper presents the data preparation initiatives and a suitable methodology that can be
used to characterize the effect of climate change on groundwater recharge. The method is based on the hydrologic
model Visual HELP which can be used to estimate potential groundwater recharge at the regional scale. The success
of Modeling depends on the accuracy of data and the mode of collecting the data. Therefore, identifying the data
needs of a particular modeling study, collection/monitoring of required data and preparation of data set form an
integral part of any groundwater modeling exercise. The main objective of this paper is to describe the exact data
required and its preparation to simulate the groundwater recharge using HELP Model Software for Yavatmal as a
study area situated in Maharashtra state, India. The impact of climate change as a pilot study is modeled by using
computer software HELP (Hydrologic Evaluation of Landfill Performance). The initiatives for data preparation
presented herein may be useful to the researchers in this field.
Modeling the Effects of Land Use Change on FloodingAdam Nayak
Due to population growth, urban areas in Oregon have been expanding, leading to increases in impervious surfaces and net losses in wetlands, riparian vegetation, and forestation in the Northwest. Utilizing ArcGIS and NOAA’s C-CAP imagery, this study classifies and analyzes urban land use changes between 1996 and 2010. These findings shed light on the importance of land use management in urban settings and are being used by local watershed councils to advocate for changes within their stream basins.

Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.

"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.

Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.

Relevance: Agricultural nutrient management is an important area of research and policy development due to
water quality degradation by nitrogen (N) and phosphorus (P). Manure application to fields without incorporation
can be a significant source of N and P loss in runoff. Winter application of dairy manure, which is commonly
practiced, is risky given frequent occurrence of runoff from snowmelt and rain-on-snow events. Many states
restrict winter spreading of dairy manure, but little process-oriented research of winter runoff and manure
nutrient loss has been conducted to support restrictions. Our project is investigating and improving the
understanding and modeling of biochemical and physical processes controlling frozen-soil and snowmelt
infiltration, runoff, and nutrient loss from soil and applied manure for actively managed dairy systems. Our
objectives are to: i) conduct multi-scale experiments to investigate processes controlling winter runoff and
nutrient loss from soil and manure; ii) develop novel model routines for winter manure runoff that can be
incorporated into process-based, field and watershed-scale models; and iii) use runoff monitoring data to
evaluate new model routines.
Impact: Our results are informing policy, guidelines, and prediction tools in northern-tier U.S. states where
winter manure application is practiced. Stakeholders include policy makers and extension agents helping to
develop manure application guidelines and farm practices, as well as scientists involved in measuring and
modeling nutrient loss in runoff from winter-spread manure. Experimental results are novel because there has
been little to no process-level research of N and P loss in runoff from winter-applied dairy manure. Results are
helping to develop new prediction tools that assess N and P loss from agroecosystems and evaluate if new
practices and technologies can reduce that loss. We have completed about 1.5 years of our four-year project. We
have conducted two lab-scale experiments investigating nutrient release from manure to water as a function of
temperature, and nutrient leaching from melting snow as a function of manure application rate and placement
within a snow-pack. These results are being processed and analyzed. Last winter we conducted preliminary in-situ
measurements of soil physical properties and climatic parameters to evaluate our approach for developing a
water and energy budget of frozen soil. We are completing installation of the field plot-scale portion of our
project that will monitor nutrient loss in runoff from winter-applied manure as function of tillage and manure
application timing treatments. The field project will be monitored for three years, beginning in winter 2105-2016.
Overall Goal and Objectives: The overall goal of our proposed project is to investigate and improve the
understanding and modeling of biochemical and physical processes controlling frozen-soil and snowmelt
infiltration, runoff, and nutrient losses from soil and applied manure for actively managed dairy systems. Our
specific, supporting objectives are to:
1. Conduct multi-scale experiments to investigate biochemical and physical processes controlling snowmelt,
snowmelt infiltration and runoff, and nutrient loss from soil and manure.
2. Develop model routines for winter manure runoff processes from Objective 1 that can be incorporated into
process-based, field- and watershed- scale models.
3. Use available runoff monitoring data to evaluate the new model routines.
Field Scale Study Approach and Preliminary Results: The field study is located in southcentral Wisconsin, near
Arlington. At this scale, we are focusing on measuring winter and early spring runoff events. Soil and weather
variables are been assessed to estimate water and energy balance budgets (Figure 2). This information will be
used for model subroutines that estimate the time and magnitude of runoff events, which can then be coupled
with multi-scale nutrient loss data to aid in estimating nutrient losses.
Figure 1. (A) Treatments include tillage (chisel/disk and no-tillage) to study the impact of soil surface roughness,
and manure application timing [no manure, early winter (no snow cover), and late winter (on top of snow)] in a
complete factorial arrangement replicated three times. (B) Each plot is 4.5 m wide by 15.2 m long with a trench
dug around their periphery to prevent runoff water from entering/leaving the individual plot area, and a
collection flume towards the bottom to collect runoff. Runoff is diverted to a box containing three collection
buckets per plot. The first bucket collects all the runoff and when filled it diverts 1/24 of the runoff volume to the
2nd bucket using a weir crown head. Similarly, the 2nd bucket has a weir head to divert 1/24 of its receiving water
volume to the 3rd bucket. This system can collect a total runoff volume of 163 mm (6.4-inches) per event.
Figure 2. Schematic of the soil and atmospheric
variables been measured. (A) The water budget
of the these systems is estimated via several
measurements of soil variables, such as liquid
water content, matric potential, depth of frost,
soil temperature, precipitation, among others.
(B) Atmospheric parameters are measured to
determine the energy budget and help establish
conditions conducent to snowmelt and increased
runoff potential.

late winter 2014-2015. In general, there was little snowmelt induced runoff in Wisconsin this past winter.
Figure 4. The lowest air temperature (A) recorded was -25.6°C. Snow (B) acts as an insulator and limits
ground heat fluxes (C), which can prevent frozen ground from thawing (D). Ground heat flux increased in
early March, leading to fast thawing of the frozen soil. A brief cold period towards the end of March shows
how fast soil can freeze. Soil temperature matched frost tube data closely (D). Data were unavailable early
in the winter season due to technical issues.

Figure 5. The liquid water content of
the soil (B) decreased as soil
temperatures decreased (A) and soil
water froze. Similarly, the soil matric
potential increased during soil
frozen periods (C). The dynamics of
a downward soil freezing front can
create an upward water flux due to
the increasing matric potential as
liquid water changes phases to a
solid. These type of phenomena can
affect nutrient distribution in the
soil profile and losses in runoff.
