Lab dip is a process by which buyers supplied swatch is matched with the varying dyes percentage in the laboratory with or without help of “DATA COLOR”
Lab dip plays an important role in shade matching & and detaching the characteristics of the dyes and chemicals are to be used in the large scale of production. So this is an important task before bulk production.
Color fastness is one of the important factors in case of buyers demand. The outstandingly important property of a dyed material is the fastness of the shade of color. Color fastness refers to the resistance of color to fade or bleed of a dyed or printed textile materials to various types of influences e.g. water, light, rubbing, washing, perspiration etc. to which they are normally exposed in textile manufacturing and in daily use. We have written a lot of articles on color fastness.

Aerobic Biodegradation of Vinegar Containing Waste Water by Mixed Culture Bac...IJERA Editor
The present study is focussed on biodegradation of the vinegar effluents by mixed culture bacteria isolated from the soil. The presence of acetic acid in the vinegar plant effluent contaminates the water and soil erodes if the effluent is released into the soil, ultimately contaminate the ground water table. It is necessary to remove acetic acid from the vinegar plant effluents. The technique used in this study in order to remove biodegradable matter is Aerobic Biodegradation. Varying initial concentrations of vinegar is synthetically prepared in the laboratory, which resembled the effluent released from the vinegar plant by adding the vinegar of 1%, 4%, 7% to 1250 ml water respectively. The mixed culture bacteria from the soil grown on standard Lysogeny Broth medium and introduced into the aerobic fluidized bed reactor after 24 hours and the bacteria (Bacilli, Cocci)biodegraded the organic matter i.e., acetic acid present in the sample. Samples analysed for vinegar concentration, DO and salinity, electrical conductivity for every 24hr, 48hr, and 72hr by volumetric analysis. The pH, DO, salinity, electrical conductivity and concentrations of the each samples measured for every 24hr, 48hr, and 72hr respectively. The pH of 1%, 4% & 7% samples varied from 6 to 9, 5 to 8.5 & 3 to 7 respectively from day1 to day3. The dissolved oxygen altered from 4ppm to 1ppm for 1% sample from day1 to day3 and from 5ppm to 2ppm for 4% vinegar sample for day1 o day3. Electrical conductivity of 1% vinegar sample increased from 52 to 58 from day1 to day3.
Effect of Alternative Scouring Agents on Dyeing Properties of Cotton/Polyeste...IOSR Journals
This research comprises of six alternative agents ((NH4)2C2O4, liquid NH3, CH3COOH, NH4OH, (COOH) 2, CH3CH2OH) at various concentrations of 1-5% used as scouring agents with NaOH as control on cotton/polyester blend fabric. The samples were bleached, mercerized and dyed. The suitability and reliability of the agents were evaluated for dyeing properties of the treated fabric. Water imbibing properties of the treated fabric, was investigated. The experimental results showed that the percentage exhaustion of indigo dye on the treated fabric were wonderful with values far above average (86.8-62.6%) except for 1% (NH4)2C2O4 that recorded slightly below average (49.7%). 2% liquid NH3 ranked the highest. The wash fastness is another interesting results where only 1-5% liquid NH3, 2% and 4% (NH4)2C2O4 that gave a grey scale rating for wash fastness of 4 (very good). The other alternative agents strongly competed at various concentrations with the control which revealed a rating of 5 (excellent wash fastness). 4% (NH4)2C2O4 scoured fabrics recorded the highest water of imbibitions (2.9 g). This implies that the alternative agents are suitable and reliable as impurity-removing (scouring) agents. The alternative agents improved the dyeing and water imbibing properties of the treated fabric far better than the control. Therefore could be employed in the textile industry.

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.

2. Abstract
Reverse Osmosis has been successfully applied on a
large scale throughout the world for treatment of
effluent and the polluted water. The Arab countries,
and some other,affluent,countries have the credit of
successfully running such large scale plants without
minding for the cost factor involved in such projects.
Here the polluted effluentis treated using R.O
technology in order to remove the pollutants. It is
a pressure driven membrane desalination process.
3. Introduction
Reverse Osmosis is a technology that is used to remove
a large majority of contaminant from water by pushing
the water under pressure through a semi-permeable
membrane.This technology is used for the treatment of
water and hazardous waste, separation processes in the
food, beverage and paper industry (Garud et al. 2014).
In this work, RO processed clean water from dye house
of cotton knit fabric dyeing has been reused for dyeing
of knit fabric.
4. How does Reverse Osmosis
work?
Reverse osmosis works by using a high pressure pump to
increase the pressure on the salt side of the RO and force the
water across the semi‐permeable RO membrane, leaving
almost all (around 95% to 99%) of dissolved salts behind in the
reject stream. The amount of pressure required depends on
the salt concentration of the feed water.

7. Testing procedure
10 gm samples of 100% cotton knit single Jersey
bleached fabric are dyed with RO clean water and
ground water in different shades such as navy, pink
and light rose. At first the samples are immersed into
the dyeing pots of the laboratory dyeing machine.
Then the dyeing pots are loaded with color solutions
according to the recipe, salt, leveling agent (Albatex
DBC 1 g/lt) and ground water and RO clean water
seperately. The sample is dyed for 20 minutes at 60oC
then soda ash is added. The dyeing procedure is again
continued for 20 minutes at same temperature. The
samples are then rinsed wash, neutralized with Acetic
acid (0.7 g/L), soaped at 90oC for 10 minutes
consequently washed
and dried.
8. Result and Discussions
1.Comparison on shade variation: Differences
between ground water and RO clean water dyed
fabric samples.The shades are almost same and
differences are insignificant visually under color
matching cabinet.
2. Comparison of Colour fastness to wash: The
wash fastness rating on bleached cotton in terms of
ground water and RO clean water dyed samples for
navy, pink and light rose shades are 4/5, 4 and
4/5 respectively. The grey scale rating lies
between 4 and 5 for all shades
9. 3. Comparison of Colour Fastness to Rubbing: In case of
navy shade ground water dyed fabric samples for the dry
and wet rubbing fastness rating is 4/5 and 3 respectively.
Similarly RO clean water dyed fabric’s rating is 4/5 and
2/3 respectively. Then the ground water dyed sample for
the dry and wet rubbing fastness rating is 4/5 and 2/3and
RO clean water dyed sample dry and wet rubbing fastness
rating was 4/5 and 2/3 for pink shade.
