Diffuse reflectance spectroscopy to estimate soil attributes of Brazilian wet...Agriculture Journal IJOEAR
Abstract— The study of soils and characterization of its attributes are continually evolving, however, for the condition of wetlands, such information is still scarce and poorly distributed. Thus, the objective of this work was to characterize spectrally the soils of a wetland area. On the study area were collected georeferenced soil samples and sent for chemical and physical analysis routine and then subjected to spectral evaluation. Were identified seven soil classes with hydromorphic characteristics in their spectral curves? The information contained in these curves then led the development of equations for soil attributes. Sand was the physical attribute of a better correlation with laboratory data and Cationic Exchange Capacity (CEC), the chemical attributes that showed better results.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

34. Basic thoughts for integrating soil names
1) Soil classification system should be no more
complicated as it is. At least, it should be easy
for soil scientists to distinguish the main soil
forming process.
2) Upper classes should be focused on main soil
forming process or elements and remain certain
stability.

3) Under classes (related with functional properties)
tend to be described quantitatively or classified
to grades to satisfy demands on soil information
in future. Just try to keep original description.

◆ a interface for soil geo-data base
◆ software tools for data processing
49. 80,000 map unite
60,000 soil types
500 soil property classes
300 basic geo-info types
Integrating soil types and property classes
should be done with all map unites
50. Interface: 4 normalized documents
• Fra (data set organizer): define data set organization
• Dir (map unite directory): define all map unites of a
data set
• Gr (geo-object type organizer): define all soil and basic
geo-info types of a data set
• Le (legend organizer): define soil and basic geo-info
types of each map unite of a data set
To connect each sections of the whole flow, a interface for
soil geo-data base was established, to characterize each
intermediate and final product exactly
Fra
GrDir
Le
51. By using the interface, software tools for data
processing were developed.
52. Dozens of intermediate and final products have been
derived.
- Soil profile data base with geo references
- China Soil Map at 1:50000 scale
- Vectored original map data

55. Data share
up to now: already supplied to 23 provinces,
1218 counties and dozens of universities
and research institutes
◆ Land soil quality evaluation
◆ Nutrient and fertilizer management
◆ Water pollution study
◆ Air pollution study, etc.
2013: Partly internet opening
56. Main contributors of China soil geo-data base at
1:50,000 scale: 16 institutes together
57. Discussion and conclusion
1. Important roles of soil info in agriculture
• Fertilization
• Water management in crop production: water
holding capacity, irrigation strategy and
equipments, etc.
• Plough techniques
……
Without combined technique development,
efforts and investments just for getting soil data
would not benefits farmers, i.e. society a lot. In
this sense large attention should also be paid
on applied research work.
58. 2. Some nature of soil information
• Soil information will never be “old” for soil
scientists.
• For the end users, i.e. farmers, industries,
consumers and policy makers, raw soil
observation might become “too old”, even they
are actually new.
• Task of DSM and the Soil scientists is to make
valuable forecasting or services for end users
by using historical and actual soil observation.
Suggestion to GSP: try to supply
soil information to improve small
farmers fertilizing practice in Asian
& Africa by means of IR technique
