I remember learning about acids and bases (or acids and alkalis) fairly early on at school. Acids were sharp vinegary substances like lemon juice, while alkalis were soapy substances, like limewater or caustic soda. We also learnt about the pH scale which measures the acidity or alkalinity of a substance. The pH scale goes from 1-14, with pH7 being completely neutral, i.e water. Anything with a very low pH is acidic, while substances with a high pH are alkaline.
Apparently yesterday was Global Handwashing Day! This is a day designed to encourage awareness of proper handwashing procedures and in the spirit of this I thought I'd take a look at a paper that came out recently about the amount of faecal matter found on mobile phones in the UK. Carried out by the London School of Hygiene and Tropical Medicine the report measured the bacterial load of people's hands and phones, including the amount of the faecal bacteria E. coli.
As a general rule in life there is always a bigger fish - for every predator there is a bigger one lurking that is ready to eat it. However it is also worth remembering that there is usually always a smaller fish as well; for every small irritating parasite there is something that can infect it.
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Musk AND Zuckerberg or Musk + Zuckerberg.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used). For example, results will contain either cake or cookie by searching cake OR cookie or cake,cookie
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
