Effect of high-temperature heat treatment duration on the purity and microstructure of MWCNTs
The effect of high-temperature heat treatment on purity and structural changes of multiwalled carbon nanotubes (MWCNTs) were studied by subjecting the raw MWCNTs (pristine MWCNTs) to 2600∘C for 60 and 120 min. Thermogravimetric analysis (TGA), X-ray diffraction, Raman spectroscopy, transmission electron microscopy (TEM) and scanning electron microscopy (SEM) were used to study the effect of heat-treatment duration on the purity and structural changes of MWCNTs. Results show that high-temperature heat treatment can be used to purify MWCNTs with proper optimization of treatment time. It was observed that 60 min heat treatment of raw MWCNTs imparts high purity and structural perfection to MWCNTs, while 120 min heat treatment imparts structural degradation to MWCNTs with collapse of the innermost shells. The present study indicates that metal impurities act as moderators in controlling the degradation of MWCNTs up to certain duration, and once the metal impurities escape completely, further heat treatment degrades the structure of MWCNTs

Studies on the influence of Microcystis aeruginosa on the ecology and fish production of carp culture ponds
In many fish ponds, blue-green algae (Cyanobacteria) constitute the greater part of the phytoplankton. Of the blue-green algae common in fish ponds, Microcystis aeruginosa is said to be a noxious species. Itsometimes forms spectacular water blooms, often with harmful consequences such as depletion of oxygen, poor growth of fish and even mass mortality among the fish. The present study was aimed atinvestigating the influence of different levels of M. aeruginosa on the water quality and fish production of carp culture ponds. For the present study, three carp culture ponds with high, moderate and low levels ofM. aeruginosa were selected. In the three ponds, physico-chemical parameters of water, phyto- and zooplankton and fish production were studied. The results indicated that the fish yield was low withconcomitant fish mortalities in the pond with high levels of M. aeruginosa compared to the other two ponds. The influence of the different levels of M. aeruginosa on other planktonic groups and in turn their effect on fish production were analyzed and discussed in the light of the existing literature
Individual case safety reports by nursing staff: a retrospective pharmacovigilance analysis
Background: The burden of adverse drug reactions is high and accounts for considerable morbidity which can be prevented if healthcare professionals have proper knowledge. Early and spontaneous reporting of ADRs is the mainstay of pharmacovigilance program. Since staff nurses are closely involved in direct patient care, they can easily identify ADRs in the early stage. This study was done to assess the extent of participation of nurses in pharmacovigilance program in our institution.Methods: Retrospective observational study was conducted by analyzing the 210 Individual Case Safety Reports (ICSR) of 2years duration. Causality assessment in the ICSR was analyzed. Severity of the reactions was categorized into mild, moderate and severe according to Modified Hartwig and Siegel scale. Descriptive statistics were used.Results: There were 177 cases reported by faculties and 33 were by the staff nurses.19 nurses reported 33 adverse effects (1:1.7) whereas 41 faculties 177 events (1:4). On analyzing the severity of reactions, 188 cases were categorized as moderate (89.5%), 20 mild (9.5%) and 2 severe (1%). In moderate category of 188 reports, 82 % reporting was by faculties and 18% by staff nurses. All the 33 reports by nurses were of moderate category (100%). In the mild and severe category, 100% reporting was by faculties. Causality analysis showed that 194 were classified as probable (92%), 14 as Possible (7%) and 2as certain (1%). In probable category 85% of reporting was by faculties and 15% by nurses, in possible group 71 % by faculties and 29% by nurses and 100% by faculties in severe category.Conclusions: Training and dedicated participation of nurses can improve reporting of ICSR
A Comparative study to Assess the Effectiveness of Acupressure Vs Reflexology on Premenstrual Syndrome among Adolescent Girls in Selected Schools at Erode, Tamilnadu
A True experimental design was used to assess the effectiveness of acupressure Vs reflexology on premenstrual syndrome among adolescent girls in selected schools at Erode, Tamilnadu.
OBJECTIVES OF THE STUDY:
1. To assess the level of premenstrual syndrome among Experimental Group I of adolescent girls before and after acupressure.
2. To assess the level of premenstrual syndrome among Experimental Group II of adolescent girls before and after reflexology.
3. To determine the effectiveness of acupressure and reflexology on pre menstrual syndrome among adolescent girls in Experimental Group I and II.
4. To compare the effectiveness of acupressure and reflexology on pre menstrual syndrome among adolescent girls in experimental group I and II.
5. To find out the association between post test scores of pre menstrual syndrome among experimental group I and II of adolescent girls with their demographic variables.
The theoretical framework used in this study was based on Imogene King’s Goal Attainment theory. The sample size of the study was 250 adolescent girls, the instrument used for data collection were a structured interview to collect demographic variable. Assessment of level of premenstrual syndrome was measured by Premenstrual Syndrome Scale (PMSS). Acupressure (Experimental group I) and Reflexology (Experimental group II) was given to adolescent girls on individual basis. Assessment of Effectiveness of Acupressure and Reflexology on level of premenstrual syndrome was measured by using same pre test scale.
MAJOR FINDINGS OF THE STUDY:
♦ Acupressure and reflexology is an intervention in reducing premenstrual syndrome as the pre test mean premenstrual syndrome score (161.98 ± 6.63, which is 81%) and (160.61± 7.15, which is 80%) was less than the post test mean premenstrual syndrome score (82.48 ± 4.23, which is 41%) and (76.74 ± 5.2, which is 38%) in experimental group I and II respectively. The calculated unpaired ‘t’ value (t= 21.91 and t = 23.46) was higher than the table value (t 124 = 1.980, p<0.05).
♦ There was a significant reduction in post test premenstrual syndrome score of adolescent girls in experimental group I than the post test premenstrual syndrome score of experimental group II. The computed ‘t’ value (t= 9.56) was greater than the table value (t 248 = 2.828, p<0.05)
♦ There is no significant association between post test premenstrual syndrome score with demographic variables of adolescent girls in experimental group I and II.
♦ There is significant association between post test premenstrual syndrome score with demographic variables of adolescent girls in experimental group I with education of parent and experimental group II with class (Standard).
CONCLUSION: Acupressure and reflexology is an effective intervention to reduce the level of premenstrual syndrome among adolescent girls. But reflexology was more effective than acupressure on premenstrual syndrome among adolescent girls. The result of the study showed that regular practice of acupressure and reflexology would be beneficial in reducing the premenstrual syndrome
Efficacy of Microencapsulated Diets on the Quality Performance of Larval and Postlarval Stages of Penaeus vannamei
The present study assessed the impact of three different commercial microencapsulated diets (MEDs) on the quality performance of larval and post-larval stages of Pacific white shrimp (Penaeus vannamei) by evaluating six key quality indicators. The results showed that at PL10 – mean survival percentage ranged from 59.67 ± 2.33 to 62.00 ± 3.21%; average body length varied from 9.11 ± 0.22 to 9.68 ± 0.23mm; size variation (CV) ranged from 4.07 ± 0.52 to 4.53 ± 0.65%; salinity stress test ranged from 90.11 ± 1.22 to 92.67 ± 3.18%, formalin stress from 93.00 ± 2.52 to 95.39 ± 1.73%, and swimming rate from 83.00 ± 3.51 to 85.00 ± 3.79%. Significant improvements were observed in all quality parameters measured in the hatchery for both larvae and post-larvae fed with MEDs. These findings suggest that the use of microencapsulation technology can enhance the nutritional value and bioavailability of feed, thereby improving survival and growth outcomes and providing insights into stage-specific nutritional vulnerabilities during the hatchery phase in P. vannamei
