Report Scope

The VST Photometric Halpha Survey of the Southern Galactic Plane and Bulge (VPHAS+) is surveying the southern Milky Way in u, g, r, i and Halpha at ∼1 arcsec angular resolution. Its footprint spans the Galactic latitude range -5° < b < +5° at all longitudes south of the celestial equator. Extensions around the Galactic Centre to Galactic latitudes ±10° bring in much of the Galactic bulge. This European Southern Observatory public survey, begun on 2011 December 28, reaches down to ∼20th magnitude (10σ) and provides single-epoch digital optical photometry for ∼300 million stars. This HiPS has been built from images from DR4 release ; the background has been globally corrected using Montage, developed at IPAC.

Aqueous environmental DNA (eDNA) is an emerging efficient non-invasive tool for species inventory studies. To maximize performance of downstream quantitative PCR (qPCR) and next-generation sequencing (NGS) applications, quality and quantity of the starting material is crucial, calling for optimized capture, storage and extraction techniques of eDNA. Previous comparative studies for eDNA capture/storage have tested precipitation and 'open' filters. However, practical 'enclosed' filters which reduce unnecessary handling have not been included. Here, we fill this gap by comparing a filter capsule (Sterivex-GP polyethersulfone, pore size 0·22 μm, hereafter called SX) with commonly used methods. Our experimental set-up, covering altogether 41 treatments combining capture by precipitation or filtration with different preservation techniques and storage times, sampled one single lake (and a fish-free control pond). We selected documented capture methods that have successfully targeted a wide range of fauna. The eDNA was extracted using an optimized protocol modified from the DNeasy® Blood & Tissue kit (Qiagen). We measured total eDNA concentrations and Cq-values (cycles used for DNA quantification by qPCR) to target specific mtDNA cytochrome b (cyt b) sequences in two local keystone fish species. SX yielded higher amounts of total eDNA along with lower Cq-values than polycarbonate track-etched filters (PCTE), glass fibre filters (GF) or ethanol precipitation (EP). SX also generated lower Cq-values than cellulose nitrate filters (CN) for one of the target species. DNA integrity of SX samples did not decrease significantly after 2 weeks of storage in contrast to GF and PCTE. Adding preservative before storage improved SX results. In conclusion, we recommend SX filters (originally designed for filtering micro-organisms) as an efficient capture method for sampling macrobial eDNA. Ethanol or Longmire's buffer preservation of SX immediately after filtration is recommended. Preserved SX capsules may be stored at room temperature for at least 2 weeks without significant degradation. Reduced handling and less exposure to outside stress compared with other filters may contribute to better eDNA results. SX capsules are easily transported and enable eDNA sampling in remote and harsh field conditions as samples can be filtered/preserved on site.

The Filter Bank is part of the Digital fields board and provides band-pass filtering for EFI and SCM spectra as well as E12HF peak and average values. The Filter Bank provides band-pass filtering for less computationally and power intensive spectra than the FFT would provide. The process is as follows: Signals are fed to the Filter Bank via a low-pass FIR filter with a cut-off frequency half that of the original signal maximum. The output is passed to the band-pass filters, is differenced from the original signal, then absolute value of the data is taken and averaged. The output from the first low-pass filter is also sent to a second FIR filter with 2:1 decimation. This output is then fed back through the system. The cascade runs 12 cycles for input at 8,192 samples/s and 13 for input at 16,384 samples/sec (EAC input only), reducing the signal (and computing power) by a factor 2 at each cascade. At each cascade a set of data is produced at a sampling frequency of 2^n from 2 Hz to the initial sampling frequency (frequency characteristics for each step are shown below in Table 1). The average from the Filter Bank is compressed to 8 bits with a pseudo-logarithmic encoder. Analog signals sent to the FBK are E12DC and SCM1. The average of the coupled E12HF signal and it's peak value are recorded over 62.5 ms windows (i.e. a 16 Hz sampling rate). Accumulation of values from signal 31.25 ms windows is performed externally. Sensor and electronics design provided by UCB (J. W. Bonnell, F. S. Mozer), Digital Fields Board provided by LASP (R.

Market Dynamics of Baghouse Filter - Fabric Dust Collector Market

Key Drivers for Baghouse Filter - Fabric Dust Collector Market

Rise of Sustainable Technology to Increase the Demand Globally

An increasing number of energy-efficient baghouse dust collectors are in demand due to tighter environmental regulations and increased energy costs. When compared to traditional shaking or reverse air processes, manufacturers are focusing on new technologies such as pulse-jet cleaning systems, which use compressed air in short bursts, to minimize energy use. To reduce waste production and maintenance costs, there is also an increasing need for fabric materials with longer lifespans and better filtration efficiency.

Strict Environment Regulation and Industrialization to Propel Market Growth

Baghouse filters are becoming more and more popular due to growing environmental rules governing emissions management and air quality. The use of efficient air pollution control devices, such as baghouse filters, is mandated by industry compliance with emission standards, which aim to minimize the discharge of particulate matter and other pollutants into the atmosphere. Baghouse filters are also in high demand due to the growth of industrial activities in several industries, such as manufacturing, power generation, mining, and chemical processing. The requirement to regulate emissions and preserve the quality of the surrounding air grows with the extent of industrial output.

Restraint Factor for the Baghouse Filter - Fabric Dust Collector Market

High Cost to Limit the Sales

Purchasing and installing baghouse filtration systems can involve a considerable initial financial outlay, particularly for big industrial plants. Some businesses, especially smaller ones, can be discouraged from implementing baghouse filters due to this cost, especially if they believe the initial outlay to be too high. Additionally, although baghouse filters are typically thought to be cost-effective throughout their operation, continuous maintenance and running costs can mount up. Certain sectors may find it burdensome to pay more for routine maintenance, which includes cleaning, replacing filters, and using energy for operation.

Impact of Covid-19 on the Baghouse Filter - Fabric Dust Collector Market

The COVID-19 epidemic has affected the baghouse filter business in both positive and negative ways. Public health now understands the significance of both indoor and outdoor air quality because of the pandemic. Increased demand for baghouse filters and other air pollution control technology as industries look to enhance the quality of the air within their buildings and the surrounding areas could result from this increased awareness. Furthermore, businesses will probably spend money on ways to lessen airborne pollutants including dust and particulate matter as a result of the heightened focus on workplace safety and cleanliness to stop the spread of COVID-19. By absorbing airborne contaminants, baghouse filters can help create safer and cleaner work environments. But a significant factor in the market expansion was the slowdown in manufacturing activity.

This paper develops a new model for the analysis of stochastic volatility (SV) models. Since volatility is a latent variable in SV models, it is difficult to evaluate the exact likelihood. In this paper, a non-linear filter which yields the exact likelihood of SV models is employed. Solving a series of integrals in this filter by piecewise linear approximations with randomly chosen nodes produces the likelihood, which is maximized to obtain estimates of the SV parameters. A smoothing algorithm for volatility estimation is also constructed. Monte Carlo experiments show that the method performs well with respect to both parameter estimates and volatility estimates. We illustrate our model by analysing daily stock returns on the Tokyo Stock Exchange. Since the method can be applied to more general models, the SV model is extended so that several characteristics of daily stock returns are allowed, and this more general model is also estimated.
