A RETROSPECTIVE STUDY OF THE PREVALENCE OF DEPRESSION DUE TO LOW HAEMOGLOBIN COUNT

Objective: It has been shown that low haemoglobin count is associated with psychological consequences and psychiatric morbidity. The association between low haemoglobin count and psychological depression has not been properly interpreted with standard values. Hence the purpose of this pilot study is to know whether there is a relation between the haemoglobin levels and the risk of developing psychiatric disorders and morbidities. To find out if there is any relationship between low haemoglobin count and depression in a rural healthcare setup. Methods: Patients from the Psychiatry Department in Saveetha Medical College and Hospital were taken. Adults over the age of 18 were included. The period between the months September 2020 and July 2021. The primary outcome was the diagnosis of psychiatric depression and their associated blood haemoglobin values. Results: Among the other types of psychiatric disorders, the female patients with low haemoglobin count were associated with a significantly higher incidence of anxiety disorders, depression and adjustment disorders. Furthermore, patients with normal haemoglobin levels were associated with a significantly lower risk of psychiatric morbidities. Conclusion: The undergone study indicates that patients with psychiatric disorders such as depression, adjustment disorders and anxiety are related with significantly low haemoglobin counts in women and not in men

Feature Extraction and Classification of Flaws in Radio Graphical Weld Images Using ANN

In this paper, a novel approach for the detection and classification of flaws in weld images is presented. Computer based weld image analysis is most significant method. The method has been applied for detecting and discriminating flaws in the weld that may corresponds false alarms or all possible nine types of weld defects (Slag Inclusion, Wormhole, Porosity, Incomplete penetration, Under cuts, Cracks, Lack of fusion, Weaving fault Slag line), after being successfully tested on80 radiographic images obtained from EURECTEST, International scientific Association Brussels, Belgium, and 24 radiographs of ship weld provided by Technic Control Co. (Poland) were used, obtained from Ioannis Valavanis Greece.. The procedure to detect all the types of flaws and feature extraction is implemented by segmentation algorithm which can overcome computer complexity problem. Our problem focuses on the high performance classification by optimization of feature set by various selection algorithms like sequential forward search (SFS), sequential backward search algorithm (SBS) and sequential forward floating search algorithm (SFFS). Features are important for measuring parameters which leads in directional to understand image. We introduced 23 geometric features, and 14 texture features. The Experimental results show that our proposed method gives good performance of radiographic images

Sensory origin of lobeline-induced sensations: a correlative study in man and cat

1. Intravenous injections of lobeline HCl into twenty-six normal young male human volunteers produced sensations of choking, pressure or fumes in the throat and upper chest at a mean threshold dose of 12 μg kg-1. 2. Reflex changes in breathing pattern usually appeared just before the sensations. Increasing the dose of lobeline increased the intensity of the sensations gradually until a dry cough appeared at a mean threshold dose of 24.3 μg kg-1. At these doses there was a mean difference of 0.3 s in the latencies for sensation and respiratory reflex; in four subjects there was no difference at all. 3. In cats anaesthetized with 35 μg kg-1 sodium pentobarbitone, injecting 25-67 μg kg-1 lobeline into the right atrium sensitized thirteen out of seventeen rapidly adapting receptors (RARs). In three out of four cats lobeline had no excitatory effect on the RARs in the absence of normal activity (i.e. when it was injected while artificial respiration was suspended), but on restarting the respiration the activity increased greatly. After injecting lobeline, the activity increased during inflation or deflation or in both phases of the respiratory cycle. It also increased greatly during deflation produced by suction of air from the lungs after lobeline. Such presumed increased activity in the RARs of man produced by forced expiration to residual volume at the time lobeline-induced sensations were expected did not enhance the sensations in any subject. 4. In all the subjects tested, forced expiration alone, which should stimulate RARs, never produced a dry cough or sensations similar to those produced by lobeline.5. The results suggest that since the reflex respiratory effects of lobeline are due to J receptors, the sensations and cough can also be attributed to them, since both events occur at about the same time, and also because the RARs, and the slowly adapting receptors (SARs), do not seem to play a primary role in producing or potentiating the sensations

Spider Search Algorithms for MIMO System and Assessment Using Simatic PCS7

This paper shows two optimization methods that are built on a spider optimization algorithm to enhance the proportional integral and derivative (PID) gain values for multiple-input-multiple-output (MIMO) arrangement which is automated with SIMATIC PCS7 Distributed Control System (SDCS). The leading methodologies are the Spider Search Algorithm (SSA) and Social Spider Optimization (SSO) which is meant primarily for optimizing PID gain values. The SSA is based on foraging strategy of colonial spiders and SSO works on the combined plan of the male and female spiders that removes the episodes of local optimization and exploration elusion. Thus, SSA and SSO are contrived for the ideal fine-tuning of PID conditions in the benchmark MIMO procedure. The system performance is understood by minimizing the integral absolute error (IAE) and the integral square error (ISE) as its objective functions. The time-domain features are examined for the aforesaid methods and thereafter compared with the previous genetic algorithm (GA). The settling time is 60s for the proposed method which is lesser than the other techniques. For illustrating the implemented controller\u27s strength, interference is manually presented in the real-time system. Findings indicate that the SSO surpasses output measures and performance indices beyond the presupposed SSA and GA intervals

Experimental studies on thermal protective coating for low pressure gas turbine blades

Paper presented at the 9th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Malta, 16-18 July, 2012.The thermal barrier coatings have many potential applications in the protection of gas turbine engine components, essentially the turbine blades. In this study micro analysis was carried out on Yitria stabilized zirconia (YSZ) coated turbine blades and the results are compared with the uncoated blades. We have used the atmosphere plasma sprayed thermal barrier coating with a thickness of 0.25 mm to withstand the high temperature of about 2000° C. A significant conclusion of the present study is that an increase in thermal coating thickness of 0.25 mm can ensure 50 % increase in the surface temperature of the turbine blades leading to a better thrust performance.dc201

Impact of Patient Counseling and Socioeconomic Factors on Initiation of Rehabilitation Program in Spinal Cord Injury Patients Presenting to a Tertiary Spine Unit in India

Study Design Prospective case series. Purpose This study aimed to investigate the impact of education, financial income, occupation, and patient counseling on the timing of enrolment in a spinal cord injury (SCI) rehabilitation program. Overview of Literature A rehabilitation program following SCI is essential to improve functional outcomes. Socioeconomic factors can affect the timing of enrolment to a rehabilitation program. Literature on the effects of socioeconomic factors among patients with SCI in the Indian scenario is limited. Methods A prospective, consecutive analysis of patients with SCI was performed with 1-year follow-up. Assessment of the timing of enrolment to a rehabilitation program was performed using the modified Kuppuswamy socioeconomic scores (MKSS). Patients admitted to the SCI unit (group A), underwent intensive individual, group, and family counseling sessions to encourage early enrolment into a rehabilitation program. Patients presenting directly for rehabilitation (group B) were analyzed for comparison. Results A total of 153 patients were recruited. Group A was composed of 122 patients who started the rehabilitation program after a mean of 28 days, compared with a mean of 149 days for 31 patients in group B. In group A, 104 patients (85%; mean MKSS, 14.02) and 18 patients (15%; mean MKSS, 15.61) enrolled for rehabilitation 0.05). Conclusions Early patient counseling in the acute care unit helps in the early enrolment of patients with poor socioeconomic demographic profile to a rehabilitation program
