Characterisation of multicrystalline solar cells

Characterisation of multicrystalline solar cells

The evaluation and assessment of the performance of photovoltaic (PV) cells in terms of measurable parameters requires the measurement of the current as a function of voltage, temperature, intensity, wind speed and spectrum. Most noticeable of all these parameters is the PV conversion efficiency η, defined as the maximum electrical power Pmax produced by the PV cell divided by the incident photon power Pin which is measured with respect to standard test conditions (STC). These conditions refer to the spectrum (AM 1.5), solar radiation intensity (1000 Wm-2), cell temperature (25 ± 2o C) and wind speed (2 mph). Tests under STC are carried out in the laboratory at a controlled environment. There have been several studies that analyze uncertainties in the laboratory measurement of solar cell efficiencies using different solar simulators and their transference to operational situations. Our preliminary results demonstrate that the short circuit current (ISC) of the solar cell decreases when irradiance is less than 1000 Wm-2 irrespective of the working temperature of the cell.

A hospital based study of pulmonary tuberculosis and HIV co-infection – In north India

This study covering the period from January 2017 to June 2017 was conducted at Department of Microbiology, SN Medical College, India. A total of 300 patients suspecting of having tuberculosis and consenting for HIV testing were included in the study. The TB diagnosis was performed using sputum microscopy (AFB staining) and all the cases were screened for HIV by using rapid HIV kits according to NACO guidelines. Overall, 29 (9.66%) cases were diagnosed as sputum positive pulmonary tuberculosis among which 2 cases (6.90 %) were sero-positive for HIV antibodies.

contains DNA (deoxyribonucleic acid), a molecule whichcontains the instructions that control the activities of thecell (see Chapter 6). Within the nucleus an even moredeeply staining area is visible, the nucleolus, which ismade of loops of DNA from several chromosomes. Thenumber of nucleoli is variable, one to five being commonin mammals.The material between the nucleus and the cell surfacemembrane is known as cytoplasm. Cytoplasm is anaqueous (watery) material, varying from a fluid to ajelly-like consistency. Many small structures can be seenwithin it. These have been likened to small organs andhence are known as organelles. An organelle can bedefined as a functionally and structurally distinct partof a cell. Organelles themselves are often surroundedby membranes so that their activities can be separatedfrom the surrounding cytoplasm. This is described ascompartmentalisation. Having separate compartmentsis essential for a structure as complex as an animal orplant cell to work efficiently. Since each type of organellehas its own function, the cell is said to show division oflabour, a sharing of the work between differentspecialised organelles.The most numerous organelles seen with the lightmicroscope are usually mitochondria (singular:mitochondrion). Mitochondria are only just visible,but films of living cells, taken with the aid of a lightmicroscope, have shown that they can move about,change shape and divide. They are specialised to carryout aerobic respiration.

MOLECULAR CLONING AND EXPRESSION ANALYSIS OF A HEAT SHOCK PROTEIN HSP90 GENE FROM BLACK TIGER SHRIMP PENAEUS MONODON

MOLECULAR CLONING AND EXPRESSION ANALYSIS OF A HEAT SHOCK PROTEIN HSP90 GENE FROM BLACK TIGER SHRIMP PENAEUS MONODON

These proteins are highly conserved among variousS. Jiang (&) Á L. Qiu Á F. Zhou Á J. Huang Á Y. Guo Á K.

Chinae-mail: Jingsg@zlen.comorganisms and collectively termed heat shock proteins(Hsps). According to their apparent molecular weights anddegrees of homology, Hsps are classified into severalfamilies, Hsp90s (83–99 kDa), Hsp70s (68–80 kDa),Hsp60s, and the small Hsps (25–28 kDa) [1].Heat shock protein 90 (Hsp 90) is one of the mostabundant cytosolic proteins in eukaryotes, amounting toapproximately 1% of soluble protein in some cells even inthe absence of stress [5]. Reported roles for Hsp90 familymembers include protein chaperoning protect cells againststress [6], oncogenic transformation [7, 8], cell cycle control [9] and antigen presentation [10]. It possesses theability to refold denatured proteins into proper conformations [11], associates with steroid hormone receptors andmaintains them in a non-functional state until hormonebinding [12, 13]. Hsp90 also interacts with other nuclear orcytoplasmic proteins, including transforming or regulatorytyrosine kinases, some serine/threonine kinases, transcription factors, cytoskeletal proteins, calmodulin, and bcsubunits of G proteins [9, 14–18].

After flyingsome 2,000 kilometers north from where they have wintered in Mexico, the hummingbirdsneed six weeks to build a nest, incubate their eggs, and raise the chicks. A second nest isfeasible only if the first fails early in the season. Quality, not quantity, is what counts inhummingbirdreproduction.(6) A nest on the lowest intact branch of an aspen will give a hummingbird a good view, aclear flight patch, and protection for her young. Male hummingbirds claim feeding territoriesin open meadows where, from late May through June, they mate with females comiing tofeed but take no part in nesting. Thus when the hen is away to feed, the nest isunguarded. While the smooth bark of the aspen trunk generally offers a poor grip for theclaws of a hungry squirrel or weasel, aerial attacks, from a hawk, owl, or gray jay, are morelikely.(12) The choice of where to build a nest is based not only on the branch itself but also onwhat hangs over it. A crooked deformity in the nest branch, a second, unusually closebranch overhead, or proximity to part of a trunk bowed by a past ice storm are featuresthat provide shelter and make for an attractive nest site. Scarcely larger than a halved golfball, the nest is painstaking constructed of spider webs and plant down, decorated andcamouflaged outside with paper-like bits of aspen bark held together with more strands of

was an integral part of the development of modern civilization. About80% of the world’s population in the developing countries rely on plantsand plant derived products for treatment of various diseases, primarilybecause of their cultural acceptability, better compatibility with thehuman body and lesser side effects.It is thus that in recent years, there has been growing interest inalternative therapies and therapeutic use of natural products, especiallythose derived from plants2-7. Moreover, a large percentage of the world’spopulation does not have access to conventional pharmacologicaltreatment and have to depend heavily on folk medicine.Infectious diseases are responsible for approximately one half of alldeaths in tropical countries. However, it was only after the recentdevelopments in the field of microbiology that has made possible thestudy of infectious diseases associated with microbes. The search fornew molecules, nowadays, has taken a slightly different route wherethe science of ethnobotany and ethnopharmacognosy are being used asguide to lead the chemist towards different sources and classes ofcompounds. The increasing prevalence of multidrug resistant strains ofbacteria and the recent appearance of strains with reducedsusceptibility to antibiotics raises the spectre of untreatablebacterial infections and adds urgency to the search for newinfection-fighting strategies8 . Although a large number of syntheticantibiotics are available in the market, yet because of the increasingresistance to antibiotics of many bacteria, plant extracts and plantcompounds are of new interest as antiseptics and antimicrobialagents 9-11 . Over 50% of all modern clinical drugs are having theirorigin in natural products12 . The pharmacological properties of themedicinal plants have been attributed to the presence of activechemical constituents which are responsible for importantphysiological function in living organisms.
