Is Vaping the right solution for giving up smoking nicotine products?
Is Vaping just a case of smoke and mirrors?
Should we be concerned about health issues caused by vaping?
With the vast increase in Vaping being led by the thought
it can stop a users addiction of smoking, do we really have
all the facts we need to determine if this is the truth?
Although e-cigarettes date back to being invented in the
1920’s, it wasn’t until the mid 2000’s that a Chinese
company, owned by pharmacist Hon Lik, created the first
modern vaping device to be sold on the high street.
Recently there has been a lot of media coverage regarding
e-cigarettes and the affect that they have on human
health, there is almost no proven scientific evidence to
say that vaping is better for people than smoking.
We are all aware that smoking is able to cause many known
illnesses and can commonly lead to death, but new stories
have come to light recently, show that vaping has a huge
detrimental effect in the same way that smoking does.
Laws have been implemented in the US since 2016 regarding
the use of vape devices which states it is illegal to
sell e-cigarettes to minors but advertising to adults is
still permitted. There isn’t as much concern that vaping
will effect children in the UK in the same way, as we
have strict limits on the levels of nicotine that can be
included in e-liquids, whereas the US do not.
Considering e-cigarettes were introduced to the market as
a less harmful alternative to smoking, there has been an
increased concern that people have taken up vaping
although they never smoked to begin with.
Electronic Cigarettes (A vape) are small devices that
use different flavoured nicotine oils, also known as
e-juices, to create smoke in a vapour form.
A vaping device does not include or contain tobacco and
therefore doesn’t allow you to produce carbon monoxide
or tar that can be formed from resins that are active
in cigarettes.
How is vape oil (e-juice) made?
Vape juices are generally made by mixing together
different flavours and nicotine with a solvent which
is usually propylene glycol.
Sometimes people will optionally use vegetable
glycerine. The solvent that is used within the mix is
the main chemical that is included in the vape oil.
Propylene glycol is an organic chemical compound that
is most commonly used within foods as an additive to
improve the flavour, colour or texture of different
products.
Currently in the UK, there is estimated to be 3.6 million people who are vaping. It is becoming
more and more common that people have taken up vaping in place of their addictive cigarette
habit, as they believe that this will be “better” for them in the long run. It has been proven
that if there is repeated high exposure to this vapour then very harmful risks could occur.
Recently there have been many cases related to e-cigarettes and the effects that they can cause.

are a quality product.
Why is Pesticide Testing Important?
Pesticides are an effective tool used by farmers all across the globe to prevent insects, rodents and other pests from
eating or spoiling their crops. Although, because these chemical compounds are deadly to these pests, it has been
important to ensure that pesticides do not have poisonous effects past insects to humans and other aspects of nature.
However, it can be difficult for communities to police pesticides and it is not as effective to test pesticide use after it
has already been applied to a field or farm. For these reasons, there have been a number of international bodies that
have joined together to create testing guidelines to ensure that the pesticides used in the U.S., Australia, Africa and
anywhere else will not result in unwanted repercussions for humans nearby. Pesticide users and manufacturers can
use certified and approved standards to check whether their pesticides meet quality and specification requirements
to work effectively without harmful consequences.
Countries Work Towards a Common Goal
Since the 1960 formation of the Convention on the Organization for Economic Co-operation and Development,
countries including the U.S, U.K., Mexico, Japan, Chile and Germany have created a set of pesticide testing protocols.
The OECD pointed to nearly 100 testing methods for the testing of these chemicals. The international group both
creates guidelines for pesticide uses as well as tests the residue of pesticides in OECD and non-OECD countries to
study their effects and determine further usage plans.
Separate from the OECD, the Collaborative International Pesticide Analytical Council, the Food and Agriculture
Organization of the United Nations, and the World Health Organization also work to regulate safe pesticide use on an
international scale. In a 2005 report published by all three organizations outlining the quality to be used in national
laboratories, they explained the importance of using standards from approved international providers.
Protecting Bees From Pesticides
As far as humans are concerned, bees are one of the most important
insects. Though they aren't the only type of bug that pollinates plants,
they are one of the most common. Bees ensure that plants produce
fruits and vegetables. Without them, whole industries would die and
many would be without a source of food. However, pesticides meant to
rid crops of other harmful insects are having an adverse effect on bee
populations around the world.
PFAS (per- and polyfluoroalkyl
substances), known as “forever
chemicals” are found in everyday
objects. Food Packaging, paints,
cosmetics, wood lacquers, sealants ,
solar panels, fire fighting foams,
artificial grass and many more
seemingly innocent products.
Generally used to prevent corrosion
and make products waterproof and
stain-resistant they are present in our
everyday life. Unfortunately they do
not break down in our environment
and as a consequence are “forever
present”. Greyhound Chromatography provides a wide range of Chromatography related products for testing and analysis of PFAS and many other 'forever chemicals'.
Are all PFAS toxic to humans?
This is a question that remains to be answered.
Research over many years will provide the data
needed to analyse the impact PFAS has on the
environment. Some PFAS, sometimes used in
construction materials are not released into the
air or water table when it rains but they are
released when buildings are demolished and the
debris is sent to landfill.
Some PFAs are of a more immediate concern as they are released into the environment when they
are used or when they come into contact with water. Small residual PFAS molecules wash off
easily and are carried to the soil, air and water very quickly. Many short-chain PFAS dissolve in
water. Gradually, over time, the PFAS sinks to the depths of oceans and rivers, settles in the
sediment and becomes a concern as marine life feeds on plants and other animals that are in the
sediment. Some PFAS such as PFOA act like detergents, they repel water and rise back to the
surface, they are then released into the atmosphere as droplets. Some scientists believe that spray
from the oceans is the biggest source of atmospheric PFAS.

Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Nucleophilic Addition of carbonyl compounds.pptxSSR02
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

8. GENERAL INFORMATION
WELLINGTON
LABORATORIES
INC.
Wellington Laboratories Inc. (Wellington) has been a reliable and respected supplier of reference
standards for over 40 years. Moreover, the company has developed a global reputation and a loyal
clientele.
This has been achieved due to:
• The superior quality of our products, which includes the accompanying documentation.
• Our consistent and timely service to all our clients.
• The technical support, pre- and post-delivery, that we gladly provide.
• Our overall dedication to customer service and continual improvement.
Considering that the products we provide are necessary to ensure the accuracy of environmental, trace
contaminant analyses, and for toxicological research, the qualifications and performance of our staff is
critical.
Wellington has put together a highly qualified team of synthetic chemists, analytical chemists, product
development chemists and administrative personnel. They are all dedicated to preparing high quality
products, supporting them with science, and delivering them to our clients.
THISCATALOGUE/NEWPRODUCTS
As in our original catalogue, Wellington continues to offer an extensive collection of native and mass-
labelled chlorinated dibenzo-p-dio:xins (PCDDs), dibenzofurans (PCDFs) and biphenyls (PCBs).
This includes ready-to-use calibration solutions and support solutions for:
• PCDD/PCDF methods, such as EPA Method 1613B,JIS Methods K 0311 and K 0312,
and European Standard Method 1948-4.
• PCB methods, such as EPA Method 1668C and Environment Canada Method
1/RM/31.
As new products or groups of products were developed and offered, additional sections were added to
our catalogue, including those presenting:
• Polybrominated Diphenyl Ethers (PBDEs) and Polybrominated Biphenyls (PBBs).
• Other Halogenated Flame Retardants (e.g. HBCDDs) and related compounds
(e.g. organo phosphates).
•
•
•
Per- and Polyfluoroalkyl substances (PFAS) .
Environmental Reference Materials (ERMs) .
Additional products including polyaromatic hydrocarbons (PAHs ), polychlorinated
naphthalenes (PCNs), and other reference standards.
In this new catalogue we have added many new native and mass-labelled PFAS, expanded our offerings of
PCNs, and introduced a separate section for organochlorine pesticides (OCPs), including newly
prepared native and mass-labelled OCPs.

9. GENERAL INFORMATION
SYNTHESIS
The chemical standards offered by Wellington are prepared using unambiguous synthetic routes and
purified using a battery of methods. All products are purified to a minimum of 98% chemical purity and
the isotopic purity of 13C-labelled products is required to be >99%. The structure of all of our compounds
is unequivocally confirmed using a variety of techniques including, as appropriate, NMR (400 or 600
MHz), HRGC with LRMS and/or HRMS, UPLC-MS/MS, and SFC/UV/MS/MS.
ACCURACY/TRACEABILITY
All of the solutions listed in this catalogue are prepared in our laboratories using:
• Microbalances calibrated regularly by an external, ISO/IEC 17025 accredited laboratory
• External weights traceable to an ISO/IEC 17025 accredited laboratory to verify
microbalance calibration
• Volumetric glassware of Class A tolerance calibrated and traceable to an
ISO/IEC 17025 accredited laboratory
• Distilled-in-glass or HPLC grade solvents
• Replicate solutions to ensure accuracy and confirm homogeneity
When possible, these solutions are compared to standard reference materials or certified standards from
another source. The expanded maximum percent relative uncertainty of solution concentrations is ± 5%,
unless stated otherwise in this catalogue.
VALIDATION/CERTIFICATION
Wellington was the first supplier of PCDDs, PCDFs and WHO PCBs to validate their solution/mixtures
using "truly blind" interlaboratory studies. Since 1991, solutions of our PCDD, PCDF and PCB standards
have been submitted to more than 30 international round-robins, resulting in over 2000 independent sets
of HRGC/HRMS data.
In addition, over the past several years, Wellington has also submitted standards for 18 interlaboratory
studies on PBDEs and 23 studies involving PFAS.
Summaries of all of these interlaboratory studies are available on request. However, in all the studies,
averages of the data received for all compounds were well within ±10% of the design values.
ANALYSIS/DOCUMENTATION
Each of our products comes with a detailed Certificate of Analysis (CofA) which includes data which the
end user should be able to replicate using equivalent instrumentation and conditions. The CofA includes
HRGC/LRMS and/or HRGC/HRMS data depending upon the intended use of the product. Those
compounds that are not amenable to GC analysis come with LC/MS data.
Additionally, all of our mass-labelled products come with data that clearly shows their isotopic purity. All
calibration sets include RRF summaries showing the required linearity. Safety Data Sheets and handling
guidelines are available for all products.
OTHER PRODUCTS/CUSTOM REQUESTS
For products not listed in this catalogue, please visit our website for updates or contact us at

The two mixtures detailed below, MDSCWDSand MFSCWDS,contain 13C-labelled PCDDand
13C-labelled PCDFcongeners, respectively. These solutions were designed to be run on a DB-5 (or
equivalent} capillary column to confirm the congener group windows for tetra-, penta-, hexa- and
heptachloro- PCDDsand PCDFs.It is intended that these mixtures, or dilutions thereof, be added
to the samples prior to extraction, at some stage during cleanup, or just prior to instrumental
analysis. The final, cleaned-up, sample extracts would thus contain all the PCDDand PCDFwindow
defining 13C-labelled congeners when used in concert with our calibration set support solutions.
This would allow the analyst to immediately confirm that the congener group windows had not
shifted and that all the PCDDsand PCDFs
had been detected where present.
Pleasenote that some 2,3,7,8-substituted PCDDsor PCDFs
are also window defining congeners and
are already present in 13C-labelled PCDDand PCDFsolution/mixes added as sampling
(e.g. EPA-23SS},
extraction (e.g. EPA-1613LCS},
cleanup, or internal standards (e.g. EPA-1613IS$}.
Therefore, they are not included in these window defining mixtures.

33. INDIVIDUAL PCDD & PCDF CONGENERS:
NATIVE AND MASS-LABELLED
Wellington offers a large selection of individual polychlorinated dibenzo-p-dioxins (PCDDs)and
polychlorinated dibenzofurans (PCDFs).We now also offer the largest selection of
mass-labelled PCDDand PCDFcongeners.
The following product groups are presented in this section:
Native Polychlorinated Dibenzo-p-dioxins (PCDDs)
Native Polychlorinated Dibenzofurans (PCDFs)
Mass-labelled PCDDs
Mass-labelled PCDFs
These compounds have all been prepared using single product, unambiguous synthetic routes
and rigorously purified using various techniques. Prior to release, their structures, chemical and
isotopic purities are confirmed using several instrumental methods and this data is summarized
in the Certificates of Analysis (CofAs).
In addition, the concentrations of the 2,3,7,8-substituted PCDDsand PCDFshave been
continually certified since 1991 through a large number of interlaboratory studies and are thus
traceable to these studies.
Since our last catalogue, we have added 3 new mass-labelled PCDDsand 2 new mass-labelled
PCDFs,namely:
MDD-27
MDD-28
MDD-1289
MDF-12389

PCDDS & PCDF S:
JAPANESEINDUSTRIAL STANDARD METHODS
JIS K 0311 AND JIS K 0312 &
ADDITIONAL PCDD/PCDF SPECIALTYSOLUTION/MIXTURES
Due to requests from clients several years ago, Wellington designed and prepared multi-point
calibration sets containing native and mass-labelled polychlorinated dibenzo-p-dioxins (PCDDs)
and polychlorinated dibenzofurans (PCDFs).These remain popular, and thus are still offered, as
they include up to 13 individual calibration solutions. This allows the user some flexibility in
selecting the calibration range that is most appropriate for their instrumentation and the
matrices being analyzed.
Moreover, these calibration sets, and their support solutions, incorporate additional mass-labelled
PCDDsand PCDFs
which can be used as part of more involved sampling and sample processing
procedure.
All of these calibration sets and support solutions are suitable for use with the Japanese
. Industrial Standards JIS K 0311 and JIS K 0312. Provided that all performance criteria are
'-I".!'!~~ achieved, they can also be used with regulatory methods from other countries.
