Why Homeowners Prefer Solar Letterboxes

/ admin

There are numerous letterboxes homeowners can make use of in order to secure their mails and documents. However, homeowners look for unique features to make simple letterboxes into wonderful decorative piece on their homes. That is why, more and more homeowners now make use of solar letterboxes. This type of letterbox has the same length and width of other mailbox. However, it provides more features such as a key lockable system as well as a wide mail slot for all your A4 mail & documents. In addition, this mailbox also has a newspaper holder. Fortunately, solar letterboxes even offer more features for homeowners. Below are some of the following.

Features stainless steel body and lid

One of the main reasons why homeowners are now using solar letterboxes is due to its stainless steel body and lid. Most of the time, homeowners use steel letterboxes to secure received mails and documents properly. However, due to extreme weather conditions, steel mailboxes may rust. As a result, mails and documents will be dirty, which can compromise important information in your mail. Fortunately, solar letterboxes are made from stainless steel which is weather resistant. Not to mention, stainless steel is easier to maintain and to clean.

Reduce the use of lights

The next reason why homeowners prefer solar powered letterboxes is they can reduce the use of lights. This is possible since solar letterboxes are equipped with LED lights that can last from 10 to 18 hours. This gets even better since the LED lights are solar powered, which mean you will not be paying expensive electric bills to light your letterboxes.

Better visibility

Since solar powered letterboxes are equipped with LED lights, homeowners are rest assured that the boxes will be more visible which can help you receive mails and documents that will be delivered during night time. Plus, the mailbox comes with 3 sets of adhesive numbers, plus a letters “A”, “B” & “/” to allow homeowners to customize their address.

Easy installation

Finally, solar powered letterboxes are easy to install. Homeowners only need simply tools such as screwdrivers, power drill and drill bits. Apart from that, solar letterboxes are wall mounted. So, you do not need to create holes on your walls to install it. And, homeowners do not need to install wiring to the LED lights.

Antibiotics And The Mode Of Action

/ admin

Technically, an antibiotic is a substance that is produced by one microorganism and it is capable of killing or inhibiting the growth of another microorganism which can a virus, bacteria, fungi, yeast, protozoan or any other pathogen.

The first antibiotic that was developed was Penicillin, a biological compound that is produced by fungi in the genus Penicillium. It was discovered by Alexander Fleming in the year 1928. After that, several other types of antibiotics produced by different species of bacteria and fungi were isolated. Some of these include cephalosporins; aminoglycosides such as streptomycin, gentamicin and kanamycin; ansamycins such as geldanamycin and carabecephems; glycopeptides like vancomycin; macrolides like erythromycin and azithromycin, penicillin, quinolone, polypeptide and sulfonamide.

All these antibiotics have different mode of action by which they act as therapeutic agents. Some of the modes of action by different antibiotics are mentioned below:

Cell Wall Synthesis Inhibitors:

Bacteria contain murein or peptidoglycan that is highly essential in maintaining the cell wall structure. Cell wall synthesis inhibitors such as beta-lactams, cephalosporins and glycopeptides block the ability of microorganisms to synthesize their cell wall by inhibiting the synthesis of peptidoglycan.

Interfering with Protein Synthesis:

These classes of antibiotics inhibit the protein synthesis machinery in the cell. Some examples include tetracyclines, chloramphenicol, aminoglycosides and macrolides.

Cell Membrane Inhibitors:

Antibiotics such as polymyxins disrupt the integrity and structure of cell membranes, thereby killing them. These set of antibiotics are mostly effective on gram negative bacteria because these are the bacteria that contain a definite cell membrane.

Effect on Nucleic Acids:

DNA and RNA are extremely essential nucleic acids present in every living cell. Antibiotics such as quinolones and rifamycins bind to the proteins that are required for the processing of DNA and RNA, thus blocking their synthesis and thereby affecting the growth of the cells.

Competitive Inhibitors:

Also referred to as anti-metabolites or growth factor analogs, these are antibiotics that competitively inhibit the important metabolic pathways occurring inside the bacterial cell. Important ones in this class are sulfonamides such as Gantrisin and Trimethoprim.
