Due to inefficient power generation and power distribution, a huge amount of energy is lost. This increases the generating cost and thus makes the overall system unfeasible. In case of renewable energy, inefficient converters are the prime cause of this energy loss. The project specifically addresses a problem related to the inefficiency of the converters that are being used in renewable energy systems. The aim was to design an efficient Isolated DC-DC Boost Converter in order to minimize the power loss and, thus, to improve the efficiency of the overall system. In doing so, a vital role can be played in promoting renewable energy that is quite sustainable and self-sufficient, and thus, playing a small part in reducing the energy deficit in Pakistan. This can have a huge impact on utilizing the renewable energy sources, especially sunlight which is abundantly available in Pakistan

17. Al-Isra’/The Night Journey

17. Al-Isra’/The Night Journey

I/We begin by the Blessed Name of Allah

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

17:01
All Glory is to The One WHO took HIS Servant Muhammad for a journey by night,
from the Grand Sacred Masjid in Holy Makkah to the Distant Masjid in Blessed Jerusalem;
the environs of which WE have especially blessed,
so that WE make him see some of OUR Wonders of Almightiness.
Truly HE - HE is All-Listening, and HE is All-Watching.

17:02
And WE granted the Scripture - the Torah - to Moses, and
made it a source of guidance for Descendants of Jacob.
Saying:
‘Do not take anyone - metaphorically or hypothetically - for a guardian other than ME!

17:03
You are all descendants of those whom WE carried in the Ark with Noah.
He was truly a grateful servant!’

17:04
And WE warned Descendants of Jacob about OUR Decision in their Scripture:
‘You will definitely create and promote corruption in the land twice, and
you will indeed exalt yourselves’ with haughtiness and become grossly overbearing.
And thus you will be punished twice.

17:05
So when the first of these two warnings came true - as the Descendants of Jacob were tuned to sinful disobedience;
WE raised against you OUR servants, people of great power - the Babylonians.
And they ravaged your homes and caused havoc throughout the land.
And it was thus a warning fulfilled!

17:06
Then WE returned to you another chance of victory against them after you had repented,
and strengthened you with wealth/prosperity and sons/manpower,
and made you even more numerous in soldiery than ever.

خواتین کی دینی تعلیم: روایت، مسائل اور عصری تحدیات

The role of madaris in spreading Islamic knowledge is an admitted fact. This blessed effort started from Dar-e-Arqam (Makkah) and Suffa (Madinah) as very first Islamic institutions. The role of madaris in producing scholars has been vital. In Islamic world, some universities and madaris got great repute. These institutions have splendid history and valuable tradition of teaching Quran and Sunnah. Along with this, madaris went through reforms time by time. There is a widespread criticism on these institutions. This is a result of sincere concern but most of the times, of mere propaganda and stereotypes. Women madaris certainly are in need of radical reforms to meet the challenges of modernity and globalization. Changing role of women requires a paradigm shift in curricula, teaching methods and training methodology. This article “Balancing one’s rights and responsibilities” is an effort to identify some of the contemporary needs of the Muslim women’s education and curricula. This is the way Muslim women can attain their dynamic role in society by adopting reforms to meet the challenges of the day.

Genetic Diversity in Pol Protein of Hiv Type-1 Prevailing Among Injecting Drug Users in Pakistan

Circulation of multiple subtypes (A, G and CRFs 02_AG) of human immunodeficiency virus type-1 (HIV-1) in select districts of Punjab province, Pakistan Owing to consistent genetic mutation and recombination, various escape mutants and/or drug-resistant mutants of human immunodeficiency virus (HIV-1) are emerging worldwide. Therefore, an understanding towards genomic characteristics of prevailing strains, particularly for drug resistance associated substitution, is very much essential to devise and implement necessary treatment and disease control intervention in disease endemic settings such as Pakistan. We processed a total of 130 plasma samples originating from HIV-treatment centers at select districts of Punjab province, Pakistan. The samples were first screened using HIV-1 Ag/Ab Combo test followed by amplification of pol gene (1084 bp) from samples positive either to antigen or both antigen and antibodies at once. Screening revealed a total of 45 samples positive (34.62%; 95% CI: 26.99-43.13) either to antigen or both antigen and antibodies at once (n = 18, 40%; 95% CI: 27.02-54.55) and antibodies alone (n = 27, 60%; 95% CI: 45.45-72.98). A maximum number of samples were positive from district Lahore [n= 19/43 (44.18%; 95% CI: 30.44-58.9)] followed by Faisalabad, n= 12/36 (33.33%; 95% CI: 20.21-49.66), Gujranwala, n= 05/23 (21.7%; 95% CI: 9.66-41.9) and Sargodha, n= 09/28 (32.1%; 95% CI: 17.93- 50.66). Odd of occurrence of HIV was significantly associated with individuals having a history of injecting drug use (68.08%; OR = 11.15; 95% CI: 53.84-79.61, p = 0.0001). The pol gene based phylogeny clustered study sequences into three distinct clades representing recombinant form 02_AG (n = 14, 77.0%; 95% CI: 54.79-91.00), subtype A (n = 2, 11.1%; 95% CI: 3.1-32.8) and G (n = 2, 11.1%; 95% CI: 3.1-32.8). Although we screened 18 samples for genotypic drug resistance analysis, except for an accessory mutation (M46K) in the protease (PR) region of a subject, we found a lack of drug resistance associated substitution in the PR. On the other hand, we found two subject (2/18) carrying resistance associated mutation (V106I) conferring a low level resistance against reverse transcriptase inhibitors. The present study concludes circulation of multiple subtypes of HIV-1 among affected population ascertaining a continuous disease surveillance coupled with evaluation of drug resistance at a higher resolution in future studies. Keywords: Human immunodeficiency virus type 1 (HIV-1); subtypes; co-circulation; molecular epidemiology; recombination analysis; drug resistance analysis Prevalence, molecular epidemiology and drug resistance pattern of human immunodeficiency virus type 1 among injecting drug users in Lahore, Pakistan Human immunodeficiency virus 1 (HIV-1) is common among injecting drug users (IDUs), and HIV- 1 positive IDUs may have potential of HIV transmission among general population through different ways. Therefore, an understanding towards current status of HIV-1 prevalence and genomic characteristics of circulating strains is crucial to devise and implement necessary interventions to control disease in developing countries like Pakistan. Total 201 plasma samples from IDUs were collected. Samples were first screened using HIV-1 Ag/Ab Combo test and then antigen positive samples were amplified for HIV-1 pol gene (1084 bp) and analyzed. Initial screening showed a total of 49 HIV samples positive (24.37%; 95% CI: 18.96-30.76). A substantial association of HIV incidence was observed in individuals with HCV infection (36.84%; 95% CI: 28.55-45.99; p<0.0001) followed by individuals involved in practices of shared injection equipment (21.17%; 95% CI: 25.07- 40.21; p<0.0001), injected previously used syringes (30.2%; 95% CI: 23.4-37.99; p=0.0016), sex with IDUs (37.78%; 95% CI: 25.11-52.37; p=0.002) and those with an age between 30-39 years (27.17%; 95% CI: 19.13-37.04; p=0.039). The pol gene-based phylogeny and subtyping classification categorized the under-study sequences representing subtype A (n = 12; 46.15%), CRF02_AG (n = 6; 23.08%), subtype C (n= 5; 19.23%) and subtype G (n = 3; 11.54%). Subsequent to genotyping resistance interpretation algorithm, one major (M46L) and two accessory (N88D, L89V) PIs mutations in the protease region while four NRTI (D67T, K70R/Q, M184V and T215F) and four NNRTI (V108T, E138A, V179I and Y181C) mutations in the reverse transcriptase region were observed. The present study concludes circulation of multiple subtypes of HIV-1 among IDUs and a continuous disease surveillance coupled with delineation of disease risk factors may provide a crucial insight into HIV prevention and treatment which could substantially curtail HIV epidemics in IDUs.
