Abstract. Stratospheric ozone transported to the troposphere is
estimated to account for 5 %–15 % of the tropospheric ozone sources.
However, the chances of intruded stratospheric ozone reaching the surface are
low. Here, we report an event of a strong surface ozone surge of
stratospheric origin in the North China Plain (NCP, 34–40∘ N,
114–121∘ E) during the night of 31 July 2021. The hourly
measurements reveal surface ozone concentrations of up to 80–90 ppbv at several
cities over the NCP from 23:00 LST (Local Standard time, = UTC +8 h) on 31
July to 06:00 LST on 1 August 2021. The ozone enhancement was 40–50 ppbv
higher than the corresponding monthly mean. A high-frequency surface
measurement indicates that this ozone surge occurred abruptly, with an
increase reaching 40–50 ppbv within 10 min. A concurrent decline in
surface carbon monoxide (CO) concentrations suggests that this surface ozone
surge might have resulted from the downward transport of a stratospheric ozone-rich and
CO-poor air mass. This is further confirmed by the vertical evolutions of
humidity and ozone profiles based on radiosonde and satellite data
respectively. Such an event of stratospheric impact on surface ozone is
rarely documented in view of its magnitude, coverage, and duration. We find that this surface ozone surge was induced by a combined effect of
dying Typhoon In-fa and shallow local mesoscale convective systems (MCSs)
that facilitated transport of stratospheric ozone to the surface. This
finding is based on analysis of meteorological reanalysis and radiosonde
data, combined with high-resolution Weather Research and Forecasting (WRF)
simulation and backward trajectory analysis using the FLEXible
PARTicle (FLEXPART) particle dispersion model. Although Typhoon In-fa on the
synoptic scale was at its dissipation stage when it passed through the NCP,
it could still bring down a stratospheric dry and ozone-rich air mass. As a
result, the stratospheric air mass descended to the middle-to-low troposphere
over the NCP before the MCSs formed. With the pre-existing stratospheric
air mass, the convective downdrafts of the MCSs facilitated the final descent
of stratospheric air mass to the surface. Significant surface ozone
enhancement occurred in the convective downdraft regions during the
development and propagation of the MCSs. This study underscores the
substantial roles of weak convection in transporting stratospheric ozone to
the lower troposphere and even to the surface, which has important implications
for air quality and climate change.

Introduction: Liver is the most commonly involved organ by metastatic disease. Secondary tumors are more frequent lesion forming more than 75%, while primary cancers of liver formed less than 25%. Imaging according to LI-RAD can give a clue for the nature of the primary lesion of live particularly hepatocellular carcinoma. Liver biopsy is still the golden standard surveillance for histopathological diagnosis of liver tumor; however, it is a traumatic procedure, but its value in reaching the definite diagnosis is superior to imaging technique. Tru cut biopsy is less traumatic than open biopsy and considered nowadays as the preferable technical way in sampling liver tissue that can be applied for both histopathology and immunohistochemistry. Secondary liver lesions were encountered to be originated from lung, breast, Pancreatobiliary tract and GIT, female genital tract, prostate and others. Objectives of the Study: To assess the efficacy of Tru cut biopsy for both histopathological examination and immunohistochemical study identification the type and origin of liver tumors. Methodology: This is a cross sectional study conducted in the Al-Sadr Teaching Hospital in Al-Najaf City, Iraq from January 2019 till December 2021.

One of the main uses of energy is the heating of fluids, mainly water and air. In the residential and industrial sectors, energy applications are diverse, mainly; Prepared food, washing clothes and personal hygiene, as well as the generation of steam and heat to process. The solar collectors represented an excellent sustainable alternative to cover the needs of these sectors. In Mexico there is a diverse market of brands and solar equipment, mostly of foreign origin. But those manufactured in our country. With selective coatings, such as titanium oxide, they are imported, and the substances and processes used are highly toxic and harmful to the environment. Given this, selective organic coatings represent an excellent alternative. It is important to increase the thermal efficiency of the solar collectors, as well as to improve the heat transfer in a thermal tank. For all the above, this research proposes a solar collector for 15 liters of water with organic selective coating and the support of a heat exchanger with nano fluid. So far, the best results are: thermal efficiency of 0.58 with a 0.1% concentration of ZnO nano fluid, thermal efficiency of 0.6 with a concentration of 0.1% ZnCuO nano fluid and thermal efficiency of 0.63 with a concentration of 0.1% CuO nano fluid.

Nos sectores residencial e industrial, as aplicações energéticas são diversas, principalmente; alimentos preparados, lavagem de roupa e higiene pessoal, bem como a geração de vapor e calor para processar. Os colectores solares representaram uma excelente alternativa sustentável para cobrir as necessidades destes sectores. No México existe um mercado diversificado de marcas e equipamentos solares, na sua maioria de origem estrangeira. Mas aqueles fabricados no nosso país. Com revestimentos selectivos, tais como óxido de titânio, são importados, e as substâncias e processos utilizados são altamente tóxicos e prejudiciais para o ambiente. Por isso, os revestimentos orgânicos selectivos representam uma excelente alternativa. É importante aumentar a eficiência térmica dos colectores solares, bem como melhorar a transferência de calor num tanque térmico. Por tudo isto, esta investigação propõe um colector solar para 15 litros de água com revestimento orgânico selectivo e o apoio de um permutador de calor com nanofluido. Até agora, os melhores resultados são: eficiência térmica de 0,58 com uma concentração de 0,1% de ZnO nano fluido, eficiência térmica de 0,6 com uma concentração de 0,1% de ZnCuO nano fluido e eficiência térmica de 0,63 com uma concentração de 0,1% de CuO nano fluido.

The Electronic Cigarette Use in Canada – Local and Global Considerations
Authors: Dahal Rudra 
Published: June 2022

Since its invention in 2003, electronic cigarettes’ (EC) users have been growing worldwide. ECs were first introduced in the market in Canada in 2004, and they remained illegal until 2018. ECs were initially marketed as a safer and cleaner alternative for the traditional combustible smoking and smoking cessation measures. Statistics show that EC use prevalence is the highest among the youths (15–19) and adolescents (20–24) years of age. EC has to promote cessation as it supplies nicotine to smokers prevent nicotine withdrawal syndrome and reduce motivation to continue smoking. EC use becomes a gateway to tobacco use and nicotine addiction. Nicotine exposure to youth and adolescents can damage the developing brain. EC use is also associated with an increased heart attack rate and other health problems. There are various reasons for using ECs, such as curiosity, quitting combustible smoking, or cutting down the number of cigarette use. Many people start ECs use before the age of 19 years. Majority of vapers like fruit flavor. Dual combustible cigarette smoking and EC use is a burning issue globally, including in Canada.
Comparative Senescence and Lifespan
Authors: M. Heshmati Hassan 
Published: June 2022

The word senescence is derived from the Latin word “senex” (meaning old). In biology, senescence is a process by which a cell ages and permanently stops dividing. Senescence is a natural universal phenomenon affecting all living organisms (e.g., humans, animals, and plants). It is the process of growing old (aging). The underlying mechanisms of senescence and aging at the cellular level are not fully understood. Senescence is a multifactorial process that can be induced by several stimuli including cellular stress, DNA damage, telomere shortening, and oncogene activation. The most popular theory to explain aging is the free radical theory. Senescence plays a role in the development of several age-related chronic diseases in humans (e.g., ischemic heart disease, osteoporosis, and cancer). Lifespan is a biological characteristic of every species. The lifespan of living organisms ranges from few hours (with mayfly) to potential eternity (with jellyfish and hydra). The maximum theoretical lifespan in humans is around 120 years. The lifespan in humans is influenced by multiple factors including genetic, epigenetic, lifestyle, environmental, metabolic, and endocrine factors. There are several ways to potentially extend the lifespan of humans and eventually surpass the maximum theoretical lifespan of 120 years. The tools that can be proposed include lifestyle, reduction of several life-threatening diseases and disabilities, hormonal replacement, antioxidants, autophagy inducers, senolytic drugs, stem cell therapy, and gene therapy.
