High-tech wood filled with air cavities could insulate your home

Removing polymers from wood, leaving tiny cavities, can drastically improve the material's insulating properties without removing too much of its strength, which might make it useful in buildings

Insulwood has better insulating properties than untreated wood

University of Maryland

A porous material made by treating wood with sodium hydroxide could better insulate homes against cold and noise.

Wood is one of the most sustainable building materials available, but it is generally a poor insulator. Now, Liangbing Hu at the University of Maryland and his colleagues have worked out how to rapidly heat wood and then slowly cool it to remove polymers known as lignin and hemicelluloses, making it porous and therefore a more effective insulator.

The researchers call the resulting material insulwood. …

An Existentialist Guide to Feeling Nothing

I recently watched “ the greatest film of all time ,” and the most boring one. In retrospect, the title alone should have been a sufficient warning: Jeanne Dielman, 23 Quai du Commerce, 1080 Bruxelles . Alas, I’m old enough to be a bit nostalgic about massive telephone address books. And massive it is. Clocking over 200 minutes, Chantal Akerman's 1975 dreary drama follows three days in the monotonous routine of Jeanne, a widow, a mother, and a prostitute. I watched Jeanne’s autopilot existence, until, staring at her back as she washes dishes, I decided to fast-forward a couple of minutes, only to discover she was still at it. And Jeanne is equally thorough when she’s busy baking, cleaning, folding laundry, or shining her son’s shoes. She speaks so scarcely and mechanically, that it’s impossible to detect any emotion or volition beyond her carefully controlled chores . Watching Jeanne Dielman is what the word “painstaking” was invented for. Chantal...

What Are SQL Stored Procedures and How Do You Create Them?

Image
Stored procedures: like functions for your SQL. A stored procedure is a batch of SQL statements created and stored on a database. You can reuse a stored procedure over and over again. A stored procedure can accept parameters, run a query, and return results. Many users can call a stored procedure and different applications can call it with different parameter values. What Are the Benefits of Using Stored Procedures? Apart from allowing multiple users and applications to reuse it, a stored procedure has other benefits. It is easy to modify. You can change a stored procedure when necessary and these updates will be reflected for all users. Furthermore, you don’t need to redeploy your application when you modify the stored procedure. It reduces network traffic because the server only passes the procedure’s name over the network and not the entire query. It improves database security since users don’t have direct access to tables. To make...
