آزادی اظہار کی حدود قیود: مسئلہ عصمت انبیاء اور اقوام متحدہ

West generally blames the Muslim world on the grounds that it does not accede to freedom of expression. But in fact, Islam gave the right of freedom of expression for the first time in history. In Rome before Islam was introduced, the rulers used to enslave the masses. Greek ministers, Roman Catholic pastorates, Spanish Inquisitions and the ministerial experts used to rebuff the individuals who used to articulate unapproved religious perspectives. The British Parliament passed a Bill of Rights in 1689. This bill proclaimed the right to speak freely. It returned amid the French Revolution of 1789 which declared speaking freely as a natural right of each person. As indicated by Holy Quran there might be no impulse in acknowledgment of the religion which is also proved from Sunnah and through the actions of the companions of Prophet Muhammad (PBUH). Blasphemy law is a law related to blasphemy, or irreverence toward holy prophets, or beliefs or religious traditions. In the provisions of Article 18 and 19 of the U.N. Charter, no limitations were made for expression which has left the room open for the defamation on name of freedom of speech. According to Islam, maintaining the honor and respect of all people is essential for regional, national and universal peace. Any articulation which abuses peace, honor and pride of any individual, race, religious gathering or any minority assembly as a rule and so forth cannot be incorporated into the meaning of flexibility of articulation or freedom of speech.

Studies on Microbial Electrochemical Cells Using Different Anode Respiring Bacteria

Microbial electrochemical cell (MXC) technology is a source of sustainable energy which comes from microorganisms. Recent advances in the fields of electromicrobiology and electrochemistry with focus on microbial electrolysis cells (MECs) has earned this technology its name as alternate “green energy”. Despite advances, this technology is still facing challenges to address low power and current density output. Thermoanaerobacter pseudethanolicus 39E (ATCC 33223), a thermophilic, Fe(III)-reducing, and fermentative bacterium, was evaluated for its ability to produce current from four electron donors xylose, glucose, cellobiose, and acetate with a fixed anode potential (+ 0.042 V vs SHE) in a microbial electrochemical cell (MXC). Under thermophilic conditions (60 °C), T. pseudethanolicus produced high current densities from xylose (5.8 ± 2.4 Am −2 ), glucose (4.3 ± 1.9 A m −2 ), and cellobiose (5.2 ± 1.6 A m −2 ). It produced insignificant current when grown with acetate, but consumed the acetate produced from sugar fermentation to produce electrical current. Low-scan cyclic voltammetry (LSCV) revealed a sigmoidal response with a midpoint potential of −0.17 V vs SHE. Coulombic efficiency (CE) varied by electron donor, with xylose at 34.8% ± 0.7%, glucose at 65.3% ± 1.0%, and cellobiose at 27.7% ± 1.5%. Anode respiration was sustained over a pH range of 5.4−8.3, with higher current densities observed at alkaline pH values. Scanning electron microscopy showed a well-developed biofilm of T. pseudethanolicus on the anode, and confocal laser scanning microscopy demonstrated a maximum biofilm thickness (Lf) greater than ~150 μm for the glucose-fed biofilm. Microbial electrochemical cells (MXCs) are devices powered by microorganisms to generate electricity via oxidation of organic substrates. It is critical to understand the significance of sediment inocula in forming anodic biofilms to improve MEC performance. Five environmental samples were evaluated for electrical current production using acetate-fed microbial electrolysis cells (MECs). Three of these samples were able to produce significant current densities ranging between 3 to 6.3 Am -2 . 16S rDNA targeted deep sequencing comparisons of anodic biofilms and sediment bacterial community structures revealed significant differences in bacterial community structures. Bacterial community producing the highest current density ixafter enrichment was dominated by the class Bacteroidia, δ-proteobacteria and Erysipelotrichi. Comparison of phylogenetic information of bacterial communities with 7 previously reported enriched samples by reconstruction of unobserved states (PICRUSt) analysis clearly distinguished the biofilm communities from the sediment inocula in terms of higher abundance of genes related to anode respiration. Principal Coordinate Analysis (PCoA) also indicated that the clustering of biofilm communities was in accordance with the predominant genera in each sample, such as Geobacter dominating one cluster of biofilms. All the sediments formed a single cluster, which included the Carolina mangrove biofilm community which showed only minor changes from its originating sediment community after enrichment. Predominantly, high current densities are associated with the enrichment of a few microorganisms, often within a single family; however, this organism can be different depending on the inoculum source. Because the selective enrichment selects for just a few bacteria, the biofilm community is significantly different from that of the sediment. While δ- proteobacteria (or the family Geobacteraceae) is dominant in many samples producing high current densities, other samples show communities with yet unidentified ARB as the major fraction.
