The document discusses different types of air sampling equipment used to measure suspended particulate matter and gaseous pollutants. High volume samplers draw in 1.1 to 1.7 cubic meters per hour of air through a filter to measure suspended particulate matter and can simultaneously sample for gaseous pollutants like SO2, NOx, and NH3. Low volume samplers draw in 1 cubic meter per hour and can measure PM10, PM2.5 and PM1.0. Lapel air samples are worn by workers to estimate breathing zone concentrations but have disadvantages like low flow rates and being uncomfortable to wear.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Professional air quality monitoring systems provide immediate, on-site data for analysis, compliance, and decision-making.
Monitor common gases, weather parameters, particulates.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
2. High Volume Samplers
Principles of operation:
• Measurement of SPM:
– Air at a high flow rate of 1.1 to 1.7 CPM
• high efficiency filter paper
• Volume of air is measured by instrument
• Amount of particles:
– Change in weight of the filter paper
• Suspended Particulate Matter (SPM)
3. High Volume Samplers
• Simultaneous sampling of gaseous pollutants:
– Air is passed through suitable reagents
– Specific gases are absorbed
– Pollutants SO2, NOx, Cl2, H2S, CS2, NH3, etc. are
analyzed to determine the concentration of
specific pollutant
5. Low Volume Sampler
• Low-volume sampling is sampling ambient air
at a flow rate of 1 cubic meter per hour.
• LVS measures the concentration of suspended
particulate
• Particles analyzed with regard to dust
components
6. Low Volume Sampler
Operation:
1. Air through the inlet of the pump
2. Flow rate is measured
3. Air flow through separator to outlet
7. Low Volume Sampler
3 inlets for
1. PM10,
2. PM 2.5
3. PM1.0
Flow rate: 1.0 m3/h
Sampling time: 1 hour and 999 h
Sample diameter: 47-50 mm
9. Lapel Air Sample
• LAS (personal air samplers)
• Worn by a worker
• Filter holder on/close to the shirt collar
• Vacuum pump on the belt.
• Best to estimate breathing zone
concentrations
10. Lapel Air Sample
• Disadvantages:
– Low flow rate (2 L/min)
– Can be contaminated by improper handling
– Expensive
– Uncomfortable to wear
– Workers must be sure to turn them on and off.
With improvements LAS may become a sampling
system of choice for determining intake
11. Lapel Air Sample
• Failure due to:
– Battery failure
– Inadequate charging
– Debris in the sample pump
– Leakage caused by vibration
– Fatigues in its valves or diaphragms
– Mechanical failure of rotary vane pumps
Air-borne suspended particulates (SPM) are measured by passing air at a high flow-rate of 1.1 to 1.7 cubic meters per minute through a high efficiency filter paper which retains the particles.
The instrument measures the volume of air sampled, while the amount of particulates collected is determined by measuring the change in weight of the filter paper as a consequence of the sampling. The passage for air reaching the filter is designed to prevent heavier settleable dust particles from reaching the filter thus measuring the concentration of Suspended Particulate Matter (SPM) in atmospheric air.*

In high volume sampler provisions have been made for simultaneous sampling of gaseous pollutants. Here the air is passed through suitable reagents that would absorb specific gases where gaseous pollutants like SO2, NOx, Cl2, H2S, CS2, NH3, etc. are analyzed subsequently by simple wet chemistry method to determine the concentration of specific pollutant*
*http://www.indiamart.com/vupkaran-pvtltd/high-volume-air-samplers.html retrieved on March 5, 2013
The Low Volume Sampler is used for measuring the concentration of suspended particulate, indoors and outdoors. The particles sampled on the filter can be gravimetrically evaluated and analyzed with regard to dust components.
The air sample is drawn in through the inlet by a vacuum pump. The air flow rate is measured by an orifice plate installed between the filter and the vacuum pump. The air sample flows through a separator for the abrasive carbon dust of the pump vanes to the outlet at the bottom of the device.
The Low Volume Sampler has 3 inlets for PM10, PM 2.5 and PM1.0 measurements, flow rate of 1.0 m3/h, the sampling time could be between 1 hour and 999 h. The diameter for sample filter is 47-50 mm.
The suspension particles concentration can be determined using a relation between the filter mass before and after exposure and the total air volume drawn
