Investigation of Galactomannan/deacetylated Chitosan Nanocomposite Films and their Anti-bacterial Properties

A little packaging is a wonderful thing, a lot of packaging is a nightmare, particularly when landfills around the world threaten to engulf our living space. The topic of edible packaging is still of interest to the food industry and other organization funding research to solve packaging dilemmas. In this research, galactomannan (GM) was used as raw material and deacetylated chitosan (DE-ChN) was used as strengthening modifier to prepare GM based packaging films. The chemical structure of the composite film was analyzed with SEM and FTIR. The properties influence for films of different DE-ChN content were studied. The obtained GM/DE-ChN nanocomposite films showed superior hydrophobicity and high tensile strength. The nanocomposite films against Escherichia coli, Bacillus subtilis, Staphylococcus aureus and Streptococcus pneumoniae showed great antibacterial properties. Moreover, the GM and GM/DE-ChN nanocomposite film showed no toxicity to RAW264.7 macrophage cells. The final obtained GM/DE-ChN packaging film provides a foundation for the potentials for futural plastic packaging alternatives.

Eating Your Own Dog Food

XML and markup technologies are a wonderful thing, but only lately has the author had the confidence to really and truly eat his own dog food, trusting entirely on the technologies familiar to him. He's learned to ignore the calls for real programmers while discovering how to copy and paste from Stack Overflow and the like in moderation. XForms, XQuery, XSLT, XSL-FO, and a proper XML database might just be all you need, at least if you know how to Google and ask for help. This, then, is nominally about building a conference registration application ensuring that we get paid for every delegate, but really all about the fact that we can now rule the world without bothering with the programmers.

Introduction:The Magic Device

In the dusty northwestern state of Rajasthan, Phoolwati was visiting a neighboring village on business. She was addressing a small circle of women dressed in sarees. Together, they formed a kaleidoscope of reds, yellows, and pinks. The colors parted obediently when an older woman, in white, pushed her way through the huddle. “What’s going on here?” bellowed the wizened old lady, speaking the rustic Hindi of the region. She pointed at the wiry newcomer, the hub of the commotion. “Who’s this?” All eyes turned to Phoolwati. “I’m here to teach the village women about the internet,” she said, as she thrust her hand out, revealing a phone with a large screen of images and text. She encountered a blank stare. “In-ter-nate,” tried Phoolwati once again, spelling it out phonetically in Hindi. “It’s a wonderful thing. You can get all kinds of information and knowledge on it.” The old lady snorted in disdain. “We’re all illiterate here, child,” she said. “Why are you wasting our time?” This was a familiar refrain to Phoolwati’s internet evangelism. She was prepared. “Who says you need to read and write to use the internet? Who says you need to know English?” demanded Phoolwati. “This is a magic device. See?” She held up her smartphone and pressed a button. The image of a microphone popped up on the screen. (This might have been more effective had the village women seen a microphone before.) “Go on. Ask it something,” Phoolwati told them. “Kuchh bhi. Anything. This has all the answers! You must be curious about something, na?” The old lady looked on incredulously. She slapped the top of her forehead in an exaggerated show of despair. Another woman had seen a city cousin toying with a smartphone once. She felt emboldened in the presence of Phoolwati’s gadget. “Show us the Taj Mahal!” she exclaimed loudly in Hindi. To instantly summon an image of the country’s most famous monument—one that none of them had ever seen—seemed an insurmountable challenge. But Google understood. The phone came alive; a video appeared on the screen. Phoolwati pressed Play.

The Views of Imam Al-Tabari on the Night of Isra and Mi'raj : رَأْيُ الإِمامِ الطَّبَرِيِّ في حادِثةِ الإسْراءِ والمِعْراج

The article addresses the views of Imam Al-Tabari on the night of Isra and Mi'raj. The importance of this article lies in the precise presentation of the details of the journey of Isra and Mi'raj from the Sacred Mosque to Al-Aqsa Mosque, and how the Messenger of Allah traveled with Jibril (peace be upon him) using Al-Burāq([1]), to pray at Al-Aqsa mosque and then going to the heavens and the details of his trip there. The objectives of this article are to clarify and to highlight the views of Imam Al-Tabari on the merits of the journey of Isra and Mi'raj. It also focuses on revealing the views of the people of interpretation regarding the events of this trip. From this article, we reach several conclusions, the most important of which is the truth of the Miracle of Isra and Mi'raj, the miracle of the great journey scenes, the scenes of the ascending to Heaven, the miracle of going out of Mecca to Jerusalem in the same night, and the miracle of Al-Burāq, it was the animal that God created. Everything about Al-Burāq was a miracle. Its color was a miracle, it would put its foot in a place and it would block the whole horizon of the eyesight, and the camels were afraid of the sound of its feet that they fled to the desert. Knowing all of that, Al-Burāq was not the only wonderful thing, but all that the Prophet saw is considered to be miracles that give advice, guidance, and vision to all people. ([1]) Al-Burāq is the creature from the heavens that carried the Islamic prophet Muhammad from Mecca to Jerusalem and back during the Isra and Mi'raj or "Night Journey", as recounted in hadith literature.
