Membrane filters can be defined as a microporous film that serves as a barrier, allowing the flow of fluids or gasses while preventing the passage of particles and microorganisms. These filters have specific ratings for their pore sizes which is vital to keep the microorganisms or particles which are bigger than the size of their pores through the process of surface capture. Membrane filtration utilizes pressure in order to force water or any other kind of carrier (fluid or gas) through a porous or semi-permeable membrane. This process separates the particulate matter that's suspended from the soluble and carrier components.

Regardless of whether it's a high school science laboratory, a medical research laboratory or scientific research facility, laboratories are hazardous environments and certain safety measures need to be implemented to prevent accidents. The following safety tips can help avoid common hazards and accidents in a laboratory.
- Basic Safety Protocols
Try to avoid working alone in a building and never work alone in a laboratory if the work you are doing presents an element of danger. Alert others to potential dangers when working with hazardous equipment or materials, or if there are any unusual hazards or conditions present. A laboratory is not the place for joking around. Distracting or startling someone working in a laboratory environment can cause an accident.

Bacterial and viral outbreaks in wild animal colonies can have a devastating impact on wildlife populations, and sometimes their long term conservation too. Early diagnosis can help wildlife managers understand what pathogens they are dealing with so they can implement measures to prevent the spread of disease where possible. ‘
Nobuto blood filter strips offer an efficient, inexpensive, and portable solution for taking blood samples from wild animals, providing a valuable tool for surveying and monitoring both healthy and diseased wildlife populations.They can be used to diagnose a wide range of common bacterial and viral diseases in wildlife and birds, as well as for detecting exposure to harmful environmental pollutants such as heavy metals and toxins.
Nobuto strips have been used to test for common avian viral diseases such as avian influenza, Newcastle disease, and West Nile virus in bird

Ceramic membranes have long since been regarded for their specific advantages in separation techniques, notably chemical and thermal stability, high flux rates, and potential for regeneration. Made with an α-Al2O3 support layer, the intermediate layers and the membrane are made of TiO2 or ZrO2 depending on pore size.
Such features have led to use in a growing range of applications, particularly in applications involving concentrated caustics and acids.

What is the purpose of spacers and shims used with the membrane test cells, and do I need them?
Crossflow velocity (CFV) refers to the linear rate of flow of the feed solution as it passes tangentially over the surface of the membrane filter and is measured in meters or feet per second. Some of the feed solution will permeate through the membrane filter, while the balance will flow along the surface of the membrane and collect as concentrate that can be recirculated through the system. The crossflow velocity has a direct impact on the fouling rate and the occurrence of concentration polarization — where a concentration gradient forms in the fluid adjacent to the membrane surface.
To calculate crossflow velocity (CFV) you will need to divide the volumetric flow rate of the feed solution in the flow channel by the cross-sectional area

Oktoberfest is an annual beer festival held over the course of two weeks during September-October in Munich, Germany. Its origins date back to October 12, 1810, when the festival was first held to celebrate the marriage of Prince Louis of Bavaria, who later became King, to Princess Therese von Sachsen-Hildburghausen. Over the years, the festival has evolved to include an amusement park and fun-fair, food and drink stalls, and several large and lively beer halls, where much of the merry-making takes place.
The Oktoberfest is a huge attraction for both locals and tourists alike. More than six million revelers attend Oktoberfest each year, consuming more than 2 million gallons of beer during the two week event.

The medicinal properties of cannabis have been recognized for centuries, and it has been used informally in traditional Chinese and Indian medicines, and more recently in western cultures without medical approval, to treat a wide range of symptoms. Over the last decade, interest in the medicinal benefits of cannabis has started to garner attention, and consequently there has been an increase in research to provide evidence of these medical effects (1).
Many western countries, including the United States, Canada and Germany now allow the medical use of cannabis. In Germany, cannabinoid medications prescribed by a physician to patients with severe diseases and no alternative treatment options are covered by health insurance (2).
The principal cannabinoid compounds derived from the cannabis plant are delta-9-tetrahydrocannabinol (THC), cannabidiol (CBD) and

The World Health Organization (WHO) defines air pollution as the "contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere." This International Clean Air Day, let's try to clean up our act and strive for clean air and blue skies by making a concerted effort to reduce our carbon footprint.
Common sources of air pollution include fires, motor vehicles, power plants, and other industrial activities. The pollutants that pose the greatest public health risk include particulate matter, carbon monoxide, lead, ozone, nitrogen dioxide, and sulfur dioxide. Exposure to these pollutants can cause respiratory conditions and diseases such as cancer, heart disease, and stroke. According to WHO, 99% of the world's population breathe heavily polluted air that exceeds their recommended

What is Chemical Oxygen Demand?
Chemical oxygen demand (COD) is the amount of dissolved oxygen needed to oxidize organic matter present in water. COD testing is conducted to determine how much organic matter is present in a water sample and how much oxidation will occur. COD testing can also be used to determine the levels of inorganic chemicals present in a sample, [1] and is used to quantify pollution levels in water. A higher COD value indicates greater pollution levels in a water sample.
What is BOD and How Does it Differ from COD?
Biochemical or Biological Oxygen Demand (BOD), is the amount of dissolved oxygen required by aerobic microorganisms to break down organic matter present in water biologically. While COD and BOD can both be used to determine pollution levels in a water sample, COD is an indication of how much oxygen is required break down organic pollutants
