Experimental investigation on the yield of solar still using manganese oxide nanoparticles coated absorber

Present research expresses an experimental investigation on nanoparticle use to enhance Solar still (SS) yield. Manganese Oxide (MNO2) is selected as a nanoparticle material and used in SS. The nanomaterial is added with the black chrome paint of the SS walls to increase the yield. The weight concentrations (WC) of MNO2 have been used from 20% to 50 to see its effect on SS yield. It has been observed that the heat transfer and water temperature enhanced by the use of the MNO2 nanoparticle with black chrome paint. The use of the MNO2 nanoparticle has improved the yield of the SS. It has also observed that the yield of SS enhanced by 19.5% compared with alone SS by use of WC of 20-50%. The SS with MNO2nanoparticle's payback time is 82 days at 20% WC than the alone SS of 98 days.This work was carried by the NPRP grant # NPRP11S-1221-170116 from the Qatar National Research Fund (a member of Qatar Foundation ).

A survey of canine tick-borne diseases in India

Background: There are few published reports on canine Babesia, Ehrlichia, Anaplasma, Hepatozoon and haemotropic Mycoplasma infections in India and most describe clinical disease in individual dogs, diagnosed by morphological observation of the microorganisms in stained blood smears. This study investigated the occurrence and distribution of canine tick-borne disease (TBD) pathogens using a combination of conventional and molecular diagnostic techniques in four cities in India. Results: On microscopy examination, only Hepatozoon gamonts were observed in twelve out of 525 (2.3%; 95% CI: 1.2, 4) blood smears. Using polymerase chain reaction (PCR), a total of 261 from 525 dogs (49.7%; 95% CI: 45.4, 54.1) in this study were infected with one or more canine tick-borne pathogen. Hepatozoon canis (30%; 95% CI: 26.0, 34.0) was the most common TBD pathogen found infecting dogs in India followed by Ehrlichia canis (20.6%; 95% CI: 17.2, 24.3), Mycoplasma haemocanis (12.2%; 95% CI: 9.5, 15.3), Anaplasma platys (6.5%; 95% CI: 4.5, 8.9), Babesia vogeli (5.5%, 95% CI: 3.7, 7.8) and Babesia gibsoni (0.2%, 95% CI: 0.01, 1.06). Concurrent infection with more than one TBD pathogen occurred in 39% of cases. Potential tick vectors, Rhipicephalus (most commonly) and/or Haemaphysalis ticks were found on 278 (53%) of dogs examined. Conclusions: At least 6 species of canine tick-borne pathogens are present in India. Hepatozoon canis was the most common pathogen and ticks belonging to the genus Rhipicephalus were encountered most frequently. Polymerase chain reaction was more sensitive in detecting circulating pathogens compared with peripheral blood smear examination. As co-infections with canine TBD pathogens were common, Indian veterinary practitioners should be cognisant that the discovery of one such pathogen raises the potential for multiple infections which may warrant different clinical management strategies

Case Report - Kocher-debre-semelaigne syndrome with pericardial effusion

We report a 10-year-old female child with hypothyroidism and limb muscle pseudohypertrophy (i.e., Kocher-Debre-Semelaigne syndrome) with pericardial effusion. The child presented with generalized swelling, breathlessness and difficulty in walking and in getting up from sitting position (of chronic duration). She had bradycardia, dull facies, marked hypertrophy of both calf muscles and nonpitting edema of legs. Pericardial effusion was detected clinically and confirmed on investigations. Muscle pseudohypertrophy was a striking feature, and hypothyroidism was confirmed on thyroid studies. The response to thyroxine replacement was excellent, with resolution of the pericardial effusion and clinical improvement. The unusual presence of pericardial effusion in Kocher-Debre-Semelaigne syndrome is discussed in the report

Effect of fin configuration parameters on performance of solar still: A review

Drinking water is a necessity not only for humanity but also for the all living organisms available in the earth today. But the availability of the potable water is not in abundant amount; hence clean water is scarce in the world today. Solar desalination system is used to turn the saline water into the freshwater by use of sunrays. Solar still is a device which can be employed for desalination. As the daily productivity of solar distiller is low so, multiple techniques have been used by various researchers to improve its productivity. But work done on the fins to enhance the distillate output is not much. Fin is a low-cost heat transfer enhancement which is used by many researchers in the solar thermal applications. Present review paper shows the use of fins in solar still and how it can be used to enhance the distillate output of solar still. At last, a table is also presented to show the use of fins to increase the distillate output alone and with the use of certain materials.Scopu
