Under appropriate growth conditions, white rot fungi like Ganoderma lucidum produce Lignin Peroxidase (LiP) as one of the extracellular oxidative enzyme that can oxidize a wide range of naturally stubborn musky pollutants. However, some important drawbacks are experienced in employing free enzymes, including unstable activity under working conditions and separation of the enzyme from reaction product. Technology in which enzyme attached to solid support has proofed an operative solution to these issues. Immobilization improves enzyme catalytic assets and functioning stability and assists enzymes various salvage, parting, and continuously automatic operations in industrial production. In this project lignocellulosic agro-industrial waste material, wheat straw was used as carbon source and solid support for LiP production by an native WRF strain Ganoderma lucidum IBL-05 through solid state fermentation under pre-optimized growth conditions. to 3.1 to 7.9fold and 2213.78 U/mg specific activity. The presence of single band (38 kDa) on sodium dodesyl sulfate gel electrophoresis define that the LiP was monomeric single aminoacid chain. Partialy purified LiP was immobilized by adopting different immobilization techniques like Ca-alginate beads, chitosan beads, silica gel, activated animal charcoal, alginate-chitosan microencapsules and CLEAs. The influence of temperature, pH, and substrate concentration on free and immobilized LiP was investigated to determine the effect of immobilization on LiP activity and stability. Silica (93%) was the best support in which LiP gave maximum immobilization efficiency. Energy-Dispersive X-ray spectroscopy (EDX) was done for conformation of immobilized LiP in the support. Results of EDX showed that LiP was successfully immobilized in different support material. The immobilized LiP was used for degradation of textile dyes and textile effluents. Maximum textile dye removal was done by activated animal charcoal (95%) and maximum textile industry effluents decolorization was done by silica (98%). Immobilized LiP was more effectual decolorizer of selected textile dyes and practical textile industry effluents.

I/We begin by the Blessed Name of Allah

The Immensely Merciful to all, The Infinitely Compassionate to everyone.

84:01
a. When the celestial realm will be split apart,

84:02
a. and obey the Command of its Rabb - The Lord,
b. as it would be obliged to do!

84:03
a. And when the earth will be leveled,

84:04
a. after it would have thrown out whatever was within it and emptied itself.

84:05
a. And it will also obey the Command of its Rabb - The Lord,
b. as it would be obliged to do!

84:06
a. O The People!
b. You would have to strive and strive hard towards your Rabb - The Lord, only then will you meet HIM.

84:07
a. So whoever will be given his record from his right hand side,

84:08
a. he will then have an easier process of accountability,

84:09
a. and return to his family, rejoicing.

84:10
a. But whoever will be given his record from behind his back,

84:11
a. he will call out for his own destruction/death.

724 Surah 84 * Al-Inshiqaq

a. and he will enter the Blazing Fire - that is kindled and ignited time and again.

84:13
a. Indeed, during his worldly life he used to live among his family, rejoicing,

The Life and Works of Ahmad Deedat: A Muslim Scholar of Christian Bible

Deedat. He debated with Christian scholars on very sensitive topics (from the point of view of Christianity) like ‘Is the Bible God’s Word?’ ‘Was Christ crucified?’ ‘The Quran or the Bible, which is God’s word?’ ‘Is Jesus God?’ and so on and proved almost all the basic doctrines of their faith from their own scriptures to be baseless. Throughout his life, deedat, faced a lot of criticism from non-Muslim scholars as well as from many Muslim scholars but he remained steadfast in his mission, and continuously struggled for preaching Islam through arguments and debates. He is best known as Muslim preacher who remained engaged in numerous intellectual inter-religious open debates with evangelical Christians, as well as video lectures, most of which relates to Islam, Christianity, Judaism & the Bible.

Use of Inquiry for Teaching Social Studies in a Lower Secondary Class at a Private School in Karachi

Social Studies is the integration of the Social Sciences and Humanities in order to promote competence in students. It enables learners to become useful citizens of the society. However, the teaching and learning of such an important subject is not satisfactorily addressed in our schools for various reasons; mainly teachers tend to rely on teaching in a traditional manner. It is perceived that teachers are knowledge givers, while students are recipients of that knowledge, and hence, the children's conceptual understanding in the subject doesn't get developed. Considering that this subject prepares children to become informed citizens, it is necessary that constructive methods and strategies should be introduced in schools for teaching Social Studies. Literature also supports innovative ideas and strategies such as discovery, problem-solving, project-based and web-based teaching and learning in order to enhance students' thinking skills and conceptual understanding. The study was undertaken in a grade seven Social Studies classroom in a private school in Karachi. The methodology used was action research as this is a practitioner's research, which enables the researcher to study the implementation of inquiry through approach using web-resources in the teaching of Social Studies. As a part of methodology, I engaged in the reconnaissance stage and made a general plan of action for carrying out the study. The cycle of action research contained; planning, action, observation and reflection. The data was collected through classroom observations, field notes, and semi-structured interviews. The findings of the study revealed that students when involved in the process of inquiry began participating actively in the lessons. Furthermore, a shift was observed in students from their dependency on textbook to independent searching and collecting information from the internet. It also provided students the opportunity of developing their communication and information-seeking skills and increased their motivation. Students were seen constructing their own knowledge, which facilitates teaching and learning in Social Studies classroom.
