The document summarizes a study that tested three trunk injection methods - Arboprof, Arborjet, and Arbocap - on young Nettle trees to determine the best method for translocating active ingredients. Arborjet was found to be the most effective method, as it showed the longest translocation profiles and was the fastest and easiest to use. While preliminary, the results suggest Arborjet may be the best injection method. Further testing is needed using adult trees and longer observation periods after injection.

Study of air pollution tolerance index of plants growing in kinassery, palakkad
Kinassery (10.7288° N, 76.6658° E) is a small Village/hamlet in Kuzhalmannam Block in Palakkad District of Kerala State, India. It is under Kannadi Panchayath. It belongs to Central Kerala Division. It is located 8 Km towards South from District head quarters Palakkad. 9 KM from Kuzhalmannam.293 KM from State capital Thiruvananthapuram. Compared to other places in Palakkad like Chandranagar, Kanjikodeetc, Kinassery seems to be a less polluted area. The major objective of the study is to understand the air pollution tolerance index of plants. Mussaenda is avery common plant species found in the road side of the region.
Mussaendaphilippica is a plant species in the family Rubiaceae that grows as a shrub or small tree (Pauwels,1998). It is native to the Philippines it is commonly grown elsewhere as an ornamental species.

This study evaluated the antibacterial properties of black tea grades grown in three different elevations in Sri Lanka. Tea samples from low, mid, and high grown areas were tested against several bacteria using an agar well diffusion assay. The results showed that antibacterial properties did not vary based on grade for low and mid grown teas, but did vary based on factory and bacterial species. High grown teas showed significant variation based on grade, factory, and bacterial species. The tea grade with the highest antibacterial effect was Broken Orange Peko from high grown areas. Staphylococcus aureus was the most susceptible bacterial species, while Escherichia coli and Vibrio parahaemolyticus were not significantly affected. Further studies are
Non-linear behavior of root and stem diameter changes in monopodial orchid
Precision agriculture aims to maximize yield with optimum resources. Vast majority of natural systems are acknowledged as complex and non-linear. However, prior to formulation of precise models, linearity tests are performed to validate plant behavior. This study has presented proof that the water uptake system in monopodial orchid is indeed non-linear. The change in physical growth of root and stem due to temperature and relative humidity factors are observed. The work focused on Ascocenda Fuchs Harvest Moon x (V. Chaophraya x Boots) orchid hybrid. Three complementary methods are presented: linearity tests through 1) regression fitting; 2) scatter plots; and 3) cross-correlation function tests. Root diameter, stem diameter, temperature, and relative humidity are logged at 15 minutes interval for a duration of 71 days. The polynomial equations derived for root diameter and stem diameter changes attained strong regression coefficients. The non-linear behavior is further confirmed by the scatter plots where no linear associations are present between the independent and dependent variables. Subsequently, the cross-correlation function tests conducted on temperature-root diameter, temperature-stem diameter, relative humidity-root diameter, and relative humidity-stem diameter combinations also revealed weak correlation. Despite using different techniques, the behavior of physical changes has been consistently proven to be non-linear.

This project investigated the effects of two-cycle marine engine exhaust water on certain green algae. Various algae species were exposed to different concentrations of exhaust water to determine toxicity levels. The effective concentration that killed 50% of the algae (EC50) was initially found to be around 3-4% exhaust water. However, using a flow-through system to lessen evaporation effects, the EC50 was found to be approximately 1.4% exhaust water. The project demonstrated that two-cycle marine engine exhaust is more toxic to algae than reported previously and that a flow-through technique provides more accurate results than static batch tests.

Aim of the present study was production biomass by induction of multiple shoots from Bambusa bambos. In general, the efficient and reproducible procedure for the propagation of bamboo can be achieved by seed propagation, clump division, and rhizome for small scale. In case of mass scale propagation, this technique would be highly insufficient and inefficient. For efficient production of bamboo, Micropropagation technique is used in large scale production. Nodal segment from fields grown clumps were used as the explants to develop a method of in vitro Micropropagation in bamboo. Plant growth hormone BAP (benzyl amino purine), KIN (kinetin), NAA (1- naphthalene acetic acid), IBA (indole-3 butyric acid), IAA (indole-3 acetic acid) was studied on in-vitro Micropropagation of the effective shoot and roots of bamboo. Effective axillary bud breaking was achieved in Murashige and Skoog (MS) media. Nodal explants culture was inoculated in both solid (0.8%) and liquid MS media and observed the maximum proliferation of shoot in solid MS medium (4/ nodal explants). The concentration of sucrose was varied and their growth was examined. The sucrose was optimized (3%). Under the optimized sucrose condition, the hormone was varied and growth was examined. Under this condition, BAP response was high. Thus the concentration of BAP was varied for further studies. The response was high in 3 mg/l of BAP concentration. This review briefly provides the state-of-the-art information on tissue culture mediated biotechnologically interventions made in bamboo for large scale Micropropagation. The established protocol will be of help to stakeholders in edible bamboo trade to conserve gene-pool and increase productivity.

Evaluation on the Impact of Flow Rate and Bed Height on the Fixed Bed Adsorpt...Associate Professor in VSB Coimbatore
The impact of flow rate and bed height on the adsorption behavior of methylene blue, Bismarck brown y, and indigo dyes on to Cedrus libani was investigated. The biomass was characterized by scanning electron microscopy as well as Fourier transformed infrared spectroscopy before and after adsorption to ascertain the functional groups responsible for the adsorption. The amount of dye adsorbed per unit mass of the biomass (qe) was calculated and was found to be dependent on the variables investigated within the experimental range. It was discovered that increase in bed height and flow rate increased the value of the dye adsorbed on to the biomass. The results obtained show that methylene blue dye adsorbed more onto the biomass, while indigo dye adsorbed at the least level.Recommended

Nanobiosensor for diclofop detection based on chemically modified afm probes ...Grupo de Pesquisa em Nanoneurobiofisica
This document summarizes the development of a nanobiosensor to detect the herbicide diclofop. The nanobiosensor is based on atomic force microscopy (AFM) and uses the acetyl-CoA carboxylase (ACCase) enzyme, which is inhibited by diclofop, as the recognition element. Computational methods including molecular docking and molecular dynamics simulations were used to model the interactions between diclofop and ACCase and optimize the sensor design. Experimentally, ACCase was attached to AFM probes and force-distance curves were collected to measure the adhesion forces between the sensor and diclofop, demonstrating selective detection of diclofop over other herbicides.

Nowadays, along with the development of technologies, scientists have invented a new technology for plants and foods. They called it GMO, and they introduced it with a lot of benefits. There is no doubt that GMO technology helps people a lot in increasing the quality of foods. It helps farmers stop wasting their time and money on pesticides. The two main types of GMO crops in use today are engineered to either produce their pesticides o be herbicide-tolerant. More than 80% of corn grown in the US is GMO Bt corn, which produces its own Bacillus thuringiensis insecticide. This has significantly reduced the need for spraying insecticides over cornfields, and dozens of studies have shown there are no environmental or health concerns with Bt corn. Scientists also proved that GMO foods are safe for humans, and they are improving the benefits of GMO foods every day. GMO foods also increase nutrition value, such as the "Golden Rice".

Title: Effect of Enzyme Concentration on the Reaction Rate (Urease Enzyme)
Introduction
Enzymes are molecules of proteins that facilitate a chemical reaction without losing its
chemical structure (Madder, 2009). An enzyme will sometimes break a substrate into
products once the substrate attaches to the active site, which is the place in the enzyme
that…
Sometimes the higher concentration of substrates in a solution can result in more
interactions with the enzymes as collations between molecules are more likely.
This experiment has the objective of evaluating the effect of the concentration of
enzymes on the chemical reaction target by the enzyme. Our hypothesis is that the more
enzymes present interacting with a specific substrate the more activity will result.
Materials and Procedure
The molecule of urea was selected as the substrate on which the enzyme urease acted
upon resulting in two products: carbon dioxide and ammonia. The presence of ammonia
was measured by determining the pH of the solution where the reaction took place.
Urea solution contained a .

Abstract The paper presents the experimental study on the use of Sequential Batch Reactor (SBR) for the degradation of phenol in the synthetic wastewater. SBR was used as a biological treatment for the reduction of COD, which is based on suspended growth system. The garden soil with cow dung was used as the seeding material in SBR, the micro-organisms that are present help in degradation of phenol as well as reducing the COD concentration. The parameters varied in the study were initial concentration of phenol in the synthetic wastewater, aeration rate and hydraulic retention time. The degradation study shows that the maximum phenol removal efficiency is 97% for 200 ppm of initial phenol concentration under 40 ml/min of aeration rate. The COD removal efficiency of 92.3% is achieved for 250 ppm of concentration of phenol. The variation in the aeration rate was found to be very effective in increasing the efficiency of SBR. For 600 ml/min of aeration, the removal efficiency of phenol and COD are respectively, 98% and 75%. But for the aeration rate of 200 ml/min the removal efficiency of COD is as high as 81.25%. Hence, with the increase in the aeration rate, there is an increase in the degradation rate of phenol and decrease in COD reduction. This study demonstrates the utilization of SBR in degrading high concentration of phenol. Keywords: Sequential Batch Reactor (SBR), Phenol, COD, Biological Treatment …

Pyrus elaeagnifolia Pallas. ssp. elaeagnifolia is a medicinal plant used in traditional medicine for the treatment
of various diseases in Turkey. The leaves of Pyrus elaeagnifolia ssp. elaeagnifolia are a rich source of arbutin,
which is a naturally occurring derivative of hydroquinone. It is found in various plant species belonging to
diverse families, such as Lamiaceae, Ericaceae, Saxifragaceae and Rosaceae. It inhibits tyrosinase and has
been employed as a cosmetic skin whitening agent. In this study, Response Surface Methodology (RSM) using a
Box Behnken Design (BBD) was employed to optimize the condition for extraction of arbutin from the leaves of
Pyrus elaeagnifolia ssp. elaeagnifolia. Three influencing factors; methanol concentration, period of ultrasoundassisted
extraction and extraction temperature were investigated in the ultrasonic aqueous extraction. The
Response Surface Methodology was applied to optimize the extraction process focused on arbutin content with
respect to the above influencing factors. The best combination of each significant factor was determined by
RSM design and optimum pretreatment conditions for maximum arbutin content were established to be
methanol concentration of 48.54 %, extraction time of 39.32 min. And extraction temperature of 43.71 0C.
Under these conditions 5.37 % of arbutin content was observed experimentally, similar to the theoretical
prediction of 5.30 %.

This document summarizes research conducted at the Beirolas WWTP in Portugal to optimize the biological treatment process and reduce energy consumption. Tests were performed using a Strathox device to determine the critical oxygen levels needed by the microbial population. The tests showed that biological reactor performance could be maintained while operating at a dissolved oxygen level of 1mg/L, below standard guidelines. This allowed energy consumption to be reduced by supplying only the necessary amount of oxygen required by the bacteria. The methodology proved easy to implement and effective at validating energy efficiency measures without compromising effluent quality.

A macro-somatic propagation study was conducted to assess the effects of rooting hormone and the level of concentration to the rooting performance of Bahai (Ormosia calavensis Azaola ex Blanco) and Bakan (Litsea philippinensis Merr.). The study was carried out in the clonal nursery of Central Mindanao University, Msuan, Bukidnon, Philippines. The experimental design used was the 2 x 4 factorial experiment arranged in Complete Randomized Design (CRD) replicated five times. The two tree species served as Factor A: Bahai and Bakan; while levels of Indole-3-Butyric Acid (IBA) served as Factor B: control – no auxin , 100 ppm, 300 ppm, and 500 ppm. Findings show that Bahai cuttings exhibited statistically higher rooting performance compared to Bakan in terms of root length and number of roots treated with 300 ppm of IBA. Data show that Bahai had an average root length of 2.042 cm compared to Bakan with only 1.355 cm. For the number of roots, Bahai had an average of 1.855 compared to Bakan with 1.376. Between the two species used, Bahai showed higher survival rate of 84.42% compared to 57.63% for Bakan. Findings suggest that both species can be treated with 300 ppm of IBA to enhance higher rooting percentage where it produces greater number and longer length of roots. It is recommended that Bahai and Bakan tree species can be potential species for propagation using macro-somatic technologies.
Ashrae rp 1301 quantification of ventilation effectiveness
This document summarizes the results of a study on quantifying ventilation effectiveness in plant and animal environments. The study involved laboratory experiments and field measurements to evaluate different methods for measuring ventilation effectiveness.
The laboratory experiments examined how ventilation parameters like the type of ventilation system, ventilation rate, and pollutant source location affect the spatial distribution of total suspended particulates and carbon dioxide concentrations. The field measurements evaluated these methods in a commercial swine building.
The results showed that the type of ventilation system and pollutant source location significantly impact pollutant concentrations, but ventilation rate did not substantially alter their spatial distribution. Based on these findings, the document provides recommendations for measuring ventilation effectiveness in animal buildings using contaminant concentration measurements at multiple sampling locations

ECO-FRIENDLY DYEING TEXTILES WITH NEEM HERB FOR MULTIFUNCTIONAL FABRICS. PART...International Journal of Technical Research & Application
Textile industries produce huge amounts of polluted
effluents, whereby over 80% of textile dyes are constituted of
Benzedrine based dyes or aromatic hazardous substances azo
groups that are normally discharged to surface and ground water
aquifers. Through the scientific awareness to reach an ecofriendly
system, this research part deals on the optimum
extraction condition of the new neem natural dye, where the
optimization parameters have technical and commercial
importance on cost and color yield. This has been carried out
using water and different concentrations of water-acetone and
water ethanol mixtures at different temperatures, pH values and
time intervals. Data observed that the optimum extraction
condition was achieved with 50% (v/v) acetone, 18% (w/v) neem
amount at pH 9 at 70oC for 60 min where 50% (v/v) wateracetone
exhibited 60 % absorbance percentage compared to (31
and 9) % of 40% (v/v) water-ethanol and water respectively. The
absorbance values are influenced by the properties of solvents
such as, the dipole moment, dielectric constant, and refractive
index values. Aqueous extraction gave less amount of pigment
and was time consuming, promoting the degradation of color
compounds while the other co-solvents increased the extract
solubility, giving high extraction capacity. pH 9 increased the
diffusion coefficients of color component and the temperature at
70oC for 60 min enhanced the de-aggregation of its molecules.
Finally, FTIR analysis investigated the presence of mainly yield
quercetin (flavonoid) compounds in neem extract which is known
to have antibacterial and antifungal properties giving chance to
be applied for antimicrobial textile dyeing in the second part of
this study.

This document describes a study that used artificial neural networks and genetic algorithms to develop performance models for a vibrating mesh nebulizer and a jet nebulizer. The models examined how different fill volumes (1, 2, and 4 mL) and nebulizer types affected drug delivery in non-invasive ventilation. In vitro, ex vivo, and in vivo experiments were conducted. The results showed that the vibrating mesh nebulizer had higher nebulization efficacy and was less affected by changes in fill volume compared to the jet nebulizer. Optimization of the in vivo model suggested increased pulmonary bioavailability and systemic absorption with the vibrating mesh nebulizer using a 2 mL fill volume.

ABSTRACT : Schefflera arboricola is used as an indoor plant in many places across the world besides the area it covers naturally. Therefore, it is produced intensely. However, it is usually produced through body cutting, which damages rootstock and allows obtaining only few cuttings from a plant. This study makes an attempt to determine the influences of rooting media and hormone applications on rooting percentage and some root morphological characters in cuttings taken from Schefflera arboricola in small amounts without damaging rootstock to the contrary of common practice. In this study, cuttings were treated with 1000 ppm, 3000 ppm, and 5000 ppm doses of IAA, IBA, NAA, and GA3 hormones, and rooting trials were carried out in sand, pearlite, and peat media. The research results show that the employed methods are significantly influential on rooting percentage and root morphological characters, and rooting percentage can be increased up to 75%.

Nowadays, along with the development of technologies, scientists have invented a new technology for plants and foods. They called it GMO, and they introduced it with a lot of benefits. There is no doubt that GMO technology helps people a lot in increasing the quality of foods. It helps farmers stop wasting their time and money on pesticides. The two main types of GMO crops in use today are engineered to either produce their pesticides o be herbicide-tolerant. More than 80% of corn grown in the US is GMO Bt corn, which produces its own Bacillus thuringiensis insecticide. This has significantly reduced the need for spraying insecticides over cornfields, and dozens of studies have shown there are no environmental or health concerns with Bt corn. Scientists also proved that GMO foods are safe for humans, and they are improving the benefits of GMO foods every day. GMO foods also increase nutrition value, such as the "Golden Rice".

Title: Effect of Enzyme Concentration on the Reaction Rate (Urease Enzyme)
Introduction
Enzymes are molecules of proteins that facilitate a chemical reaction without losing its
chemical structure (Madder, 2009). An enzyme will sometimes break a substrate into
products once the substrate attaches to the active site, which is the place in the enzyme
that…
Sometimes the higher concentration of substrates in a solution can result in more
interactions with the enzymes as collations between molecules are more likely.
This experiment has the objective of evaluating the effect of the concentration of
enzymes on the chemical reaction target by the enzyme. Our hypothesis is that the more
enzymes present interacting with a specific substrate the more activity will result.
Materials and Procedure
The molecule of urea was selected as the substrate on which the enzyme urease acted
upon resulting in two products: carbon dioxide and ammonia. The presence of ammonia
was measured by determining the pH of the solution where the reaction took place.
Urea solution contained a .

Abstract The paper presents the experimental study on the use of Sequential Batch Reactor (SBR) for the degradation of phenol in the synthetic wastewater. SBR was used as a biological treatment for the reduction of COD, which is based on suspended growth system. The garden soil with cow dung was used as the seeding material in SBR, the micro-organisms that are present help in degradation of phenol as well as reducing the COD concentration. The parameters varied in the study were initial concentration of phenol in the synthetic wastewater, aeration rate and hydraulic retention time. The degradation study shows that the maximum phenol removal efficiency is 97% for 200 ppm of initial phenol concentration under 40 ml/min of aeration rate. The COD removal efficiency of 92.3% is achieved for 250 ppm of concentration of phenol. The variation in the aeration rate was found to be very effective in increasing the efficiency of SBR. For 600 ml/min of aeration, the removal efficiency of phenol and COD are respectively, 98% and 75%. But for the aeration rate of 200 ml/min the removal efficiency of COD is as high as 81.25%. Hence, with the increase in the aeration rate, there is an increase in the degradation rate of phenol and decrease in COD reduction. This study demonstrates the utilization of SBR in degrading high concentration of phenol. Keywords: Sequential Batch Reactor (SBR), Phenol, COD, Biological Treatment …

A macro-somatic propagation study was conducted to assess the effects of rooting hormone and the level of concentration to the rooting performance of Bahai (Ormosia calavensis Azaola ex Blanco) and Bakan (Litsea philippinensis Merr.). The study was carried out in the clonal nursery of Central Mindanao University, Msuan, Bukidnon, Philippines. The experimental design used was the 2 x 4 factorial experiment arranged in Complete Randomized Design (CRD) replicated five times. The two tree species served as Factor A: Bahai and Bakan; while levels of Indole-3-Butyric Acid (IBA) served as Factor B: control – no auxin , 100 ppm, 300 ppm, and 500 ppm. Findings show that Bahai cuttings exhibited statistically higher rooting performance compared to Bakan in terms of root length and number of roots treated with 300 ppm of IBA. Data show that Bahai had an average root length of 2.042 cm compared to Bakan with only 1.355 cm. For the number of roots, Bahai had an average of 1.855 compared to Bakan with 1.376. Between the two species used, Bahai showed higher survival rate of 84.42% compared to 57.63% for Bakan. Findings suggest that both species can be treated with 300 ppm of IBA to enhance higher rooting percentage where it produces greater number and longer length of roots. It is recommended that Bahai and Bakan tree species can be potential species for propagation using macro-somatic technologies.
Ashrae rp 1301 quantification of ventilation effectiveness
This document summarizes the results of a study on quantifying ventilation effectiveness in plant and animal environments. The study involved laboratory experiments and field measurements to evaluate different methods for measuring ventilation effectiveness.
The laboratory experiments examined how ventilation parameters like the type of ventilation system, ventilation rate, and pollutant source location affect the spatial distribution of total suspended particulates and carbon dioxide concentrations. The field measurements evaluated these methods in a commercial swine building.
The results showed that the type of ventilation system and pollutant source location significantly impact pollutant concentrations, but ventilation rate did not substantially alter their spatial distribution. Based on these findings, the document provides recommendations for measuring ventilation effectiveness in animal buildings using contaminant concentration measurements at multiple sampling locations

Textile industries produce huge amounts of polluted
effluents, whereby over 80% of textile dyes are constituted of
Benzedrine based dyes or aromatic hazardous substances azo
groups that are normally discharged to surface and ground water
aquifers. Through the scientific awareness to reach an ecofriendly
system, this research part deals on the optimum
extraction condition of the new neem natural dye, where the
optimization parameters have technical and commercial
importance on cost and color yield. This has been carried out
using water and different concentrations of water-acetone and
water ethanol mixtures at different temperatures, pH values and
time intervals. Data observed that the optimum extraction
condition was achieved with 50% (v/v) acetone, 18% (w/v) neem
amount at pH 9 at 70oC for 60 min where 50% (v/v) wateracetone
exhibited 60 % absorbance percentage compared to (31
and 9) % of 40% (v/v) water-ethanol and water respectively. The
absorbance values are influenced by the properties of solvents
such as, the dipole moment, dielectric constant, and refractive
index values. Aqueous extraction gave less amount of pigment
and was time consuming, promoting the degradation of color
compounds while the other co-solvents increased the extract
solubility, giving high extraction capacity. pH 9 increased the
diffusion coefficients of color component and the temperature at
70oC for 60 min enhanced the de-aggregation of its molecules.
Finally, FTIR analysis investigated the presence of mainly yield
quercetin (flavonoid) compounds in neem extract which is known
to have antibacterial and antifungal properties giving chance to
be applied for antimicrobial textile dyeing in the second part of
this study.

This document describes a study that used artificial neural networks and genetic algorithms to develop performance models for a vibrating mesh nebulizer and a jet nebulizer. The models examined how different fill volumes (1, 2, and 4 mL) and nebulizer types affected drug delivery in non-invasive ventilation. In vitro, ex vivo, and in vivo experiments were conducted. The results showed that the vibrating mesh nebulizer had higher nebulization efficacy and was less affected by changes in fill volume compared to the jet nebulizer. Optimization of the in vivo model suggested increased pulmonary bioavailability and systemic absorption with the vibrating mesh nebulizer using a 2 mL fill volume.
