Abstract: Library is a learning institution that exists in our society from ancient times. It is a place where interaction between human and information takes place and intends to satisfy the information and social needs. Libraries play a vital role for a nation by preserving its cultural heritage. In the modern age with the abundance of information, libraries assist the society by maintaining and disseminating the relevant information as and when required.

Abstract: The proliferative capability of many invasive pathogens is limited by the bioavailability of iron. Pathogens have thus developed strategies to obtain iron from their host organisms. In turn, host defense strategies have evolved to sequester iron from invasive pathogens. This review explores the mechanisms employed by bacterial pathogens to gain access to host iron sources, the role of iron in bacterial virulence, and iron-related genes required for the establishment or maintenance of infection. Host defenses to limit iron availability for bacterial growth during the acute-phase response and the consequences of iron overload conditions on susceptibility to bacterial infection are also examined. The evidence summarized herein demonstrates the importance of iron bioavailability in influencing the risk of infection and the ability of the host to clear the pathogen.

Abstract: The three main pillars of sustainability are the society, the environment, and the economy (people, planet, and profit). The key drivers that sustain these three pillars are energy and resource efficiency, a clean and ‘green’ environment that incorporates effective waste reduction and management, and finally cost-effective production. Sustainable manufacturing implies technologies and/or techniques that target these key drivers during product manufacture. Because of the effort and costs involved in the machining of titanium and its alloys, there is significant scope for improved sustainable manufacturing of these materials. Titanium and its alloys are extensively used for specialized applications in aerospace, medical, and general industry because of their superior strength-to-weight ratio and corrosion resistance. They are, however, generally regarded as difficult-to-machine materials. This article presents an overview of previous and current work and trends as regards to sustainable machining of titanium and its alloys. This article focuses on reviewing previous work to improve the sustainable machining of titanium and its alloys with specific reference to the selection of optimum machining conditions, effect of tool materials and geometry, implementing advanced lubrication and/or cooling techniques, and employing advanced and hybrid machining strategies. The main motivation is to present an overview of the current state of the art to discuss the challenges and to suggest economic and environment-friendly ways for improving the machinability of titanium and its alloys.

Abstract: As we know that instructional technology is an essential element of educational technology which contributes to the efficacy as well as efficiency of teaching learning process. In the present scenario the concept of teaching supplemented by technological devices is not new. Technology not only helps to bring about desirable changes in the teaching learning process but also it makes the entire process more interesting, motivating and interactive. Today’s students are ever more techno-friendly so there has been an increased demand to bring advanced educational technologies into the classroom. They expect that the presentation of the content should meet with their needs. They cannot be satisfied with only one-way conventional methods of teaching. Technology experts have claimed that use of computer technologies can transform teaching learning process positively because technology not only provides increased access to information, but also provides unlimited opportunities to teachers and students to collaborate with peers and experts. Technology also helps to exchange ideas and explore topics in different ways that would not be possible in a traditional classroom approach.

Abstract: Zinnia elegans is valued for its medicinal and ornamental properties. Moreover, it is preferred for its adaptability in varied environmental conditions. Besides its global presence, cultivated in all agroecological regions in Pakistan. This study was designed to investigate impact of different edaphic and climatic conditions including sunshine, slop, moisture, day length and altitude on the gene expressions controlling length, width and size (area) of leaves, sepals, petals, stamens and carpels. The study also investigated allometric factors and relationships. Three major sample sites were identified with long, short and moderate sunshine, slope and moisture content (Burmas-Gilgit, Sonikot-Gilgit and Daniyore-Gilgit). 100 samples were collected from each sampling site making a total of 300 samples. Current study revealed that there are 6 sepals. Mean length of sepals recorded was 0.86 cm, width 0.40 cm and area was 0.35 cm² (R² = 0.3151). Similarly, there are 6 petals in number. Mean length was 2.51 cm, width 1.03 cm, and area was 2.60 cm² (R² = 0.0131). Mean length of stamens was 1.12 cm, width 0.19 cm and a area of 0.21 cm² (R² = 0.3151). Mean length of carpels was 0.09 cm, width 0.01 cm, and area was 0.01 cm² (R² = 0.134). Leaf mean length was 0.49 cm, width 0.29 cm, and area 2.05 cm². Research concluded that different parts of the plant behaved differently towards varied climatic conditions. Stamens and carpels prefer moderate sunshine and day length and plain neutral (non slopy areas). Similarly, leaf area (size) showed an inverse relation to sunshine and day length whereas there was a direct relation between the leaf size and the moisture content. Contrarily, leaf has shortest length in moderate non slopy areas with broadest width. In an overall preference of plant, best growth was recorded in the slop neutral areas (Sonikot in Gilgit) with moderate sunshine, day length and moisture content. Findings from the research suggest that Zinnia elegans commercial nurseries can be established better in Sonikot as compared to rest of the areas in Gilgit.
