After four years of visual study and two years of photographic study of refinery clouds and refinery cloud systems, it is concluded that the combined skills of weather modification and engineering can be used to design giant cloud chambe’rs that can control cloud formation on a local level.

Abstract:

The Wilson cloud chamber, invented in 1911 by Scottish physicist Charles Wilson, is a remarkably simple and effective charged particle detector. Cloud chambers were used regularly in particle physics experiments for decades, until being supplanted by bubble chambers. In this article, we describe a lab activity that is suitable for introductory-level physics students using a cloud chamber to measure the rate of alpha decay in the atmosphere. In performing this experiment, the students deepen their understanding of alpha decay, including the random nature of the process. They also become acquain

Abstract:

Abstract Cosmic ray (CR) particles are high-energy particles originating from outer space that often reach the ground as alpha and proton particles, which can be studied using particle detectors. While investigating CR particles is a complex process, cloud chambers offer a simple means of detection. However, they cannot measure count rates directly. To overcome this limitation, we developed a deep learning model for real-time count rate determination of particles in a homemade cloud chamber (DeepHCC), implementing YOLOv5 pre-trained weights to use with our homemade cloud chamber.

Abstract:

Quantifying the aerosol/cloud-mediated radiative effect at a global scale requires simultaneous satellite retrievals of cloud condensation nuclei (CCN) concentrations and cloud base updraft velocities (Wb). Hitherto, the inability to do so has been a major cause of high uncertainty regarding anthropogenic aerosol/cloud-mediated radiative forcing. This can be addressed by the emerging capability of estimating CCN and Wb of boundary layer convective clouds from an operational polar orbiting weather satellite. Our methodology uses such clouds as an effective analog for CCN chambers. The cloud bas

Abstract Riming electrification is the main charge separation mechanism of thunderstorms, occurring mainly during graupel particle–ice crystal collisions. Laboratory experiments have found that charge separation polarity and magnitude depend critically on cloud water content and temperature. Several groups have mapped this dependence, but there are substantial differences between their results. These conflicting laboratory-derived riming electrification topographies can be tested by comparing them to field observations.

Using a coordinate transformation we find the density of the recaptured atomic cloud as a function of time. This allows us to investigate the effect of experimental paramet

Abstract:

This paper proposes a monitoring system retro-fittable for existing Intravenous (IV) infusion setup. Traditionally, doctors and nurses use their experience to estimate the time required by an IV bottle to empty which makes the IV therapy vulnerable to human error. The current study proposes an internet connected monitoring platform for IV drip chambers. The device enables doctors and nursing staff to monitor the drip parameters wirelessly while emphasizing on low costs and high degree of reliability. It has two main units, namely chamber unit and pole unit. Chamber unit houses two types of sen

Abstract:

This study numerically investigates precipitation enhancement from cumuliform clouds in three different climate regions: (1) Arid climate of the United Arab Emirates (UAE); (2) maritime climate of Thailand; and (3) continental climate of Serbia. Recently developed core/shell sodium chloride (NaCl)/titanium dioxide (TiO2) nanostructure (CSNT) aerosol was tested as a precipitation enhancer in all three climate regions. Previous experimental studies in cloud chambers and idealized numerical simulations demonstrated that CSNT is a significantly more effective precipitation enhancer than the tradit

Abstract:

Abstract. One of the key challenges for muographic studies is to reveal the detailed 3D density structure of a volcano by increasing the number of observation directions. 3D density imaging by multi-directional muography requires that the individual differences in the performance of the installed muon detectors are small and that the results from each detector can be derived without any bias in the data analysis. Here we describe a pilot muographic study of the Izu–Omuroyama scoria cone in Shizuoka Prefecture, Japan, from 11 directions, using a new nuclear emulsion detector design optimized fo

Abstract:

Petunia hybrids `Snow Cloud' plants with leaf area indices of 3.5 to 4 were grown under widely varying photosynthetically active radiation and temperature conditions in growth chambers and greenhouses in California and New Jersey. The rate of shoot dry weight gain per unit area increased with increasing photosynthetic photon flux density (PPFD) and had a convex relationship with air temperature. A mathematical model incorporating these patterns fit the data with an R2 of 0.985. This model provides a tool for analyzing production characteristics such as dry matter production efficiency.

Abstract:

Fast ions create linear trails of intense atomic disorder in many solids. The particle tracks are in themselves scientifically interesting because they consist of unique, localized radiation damage. They also are noteworthy for their diverse practical uses, which range from improved high field superconductors to mineral exploration and bird altimetry. The two areas—what tracks are and what they do practically—are the subjects of this introduction and the following three articles. Although the mechanism for producing tracks in insulators is semi-quantitatively well-established, there is a disti

Abstract:

Coatings play a crucial role in the functionality of vacuum chambers in particle accelerators, serving a dual goal by efficiently facilitating pumping and mitigating electron cloud effects. However, their impact on the surface impedance of the chamber walls raises concerns, potentially affecting the machine performance and imposing limitations on achievable energies and currents. Therefore, an electromagnetic characterization is essential for a comprehensive study of accelerator structures, particularly in the context of the next-generation machines where the demand for extremely short particl
