Cellular manufacturing layout design using heuristic clustering algorithm and lpp model

This mathematical model forms machine cells, optimises the costs of unassigned machines and components, and designs the shop floor cell layout to have minimal movement of materials. The complete similarity measure algorithm forms machine cells and part families in a refined form. Later, exceptional elements are eliminated in the optimisation model by using machine duplication and sub-contracting of parts. Then the shop floor layout is designed to have optimised material movements between and within cells. An evaluation of the cell formation algorithm’ performance is done on the benchmark problems of various batch sizes to reveal the process’s capability compared with other similar methods. The data of machining times are acquired and tabulated in a part incidence matrix, which is used as input for the algorithm. The results from the linear programming optimisation model are that costs are saved, machines are duplicated, parts are sub-contracted, and there are inter- and intra-cellular movements. Finally, the output of the inbound facility design is the floor layout, which has machine cell clusters within the optimised floor area.

"an indian scenario: emerging advances in nanotechnology as drug delivery system in rheumatoid arthritis".

There are several significant assays including bioavailability, Toxicity, high clearance, and further current therapies require higher and frequent dosing to gain desired therapeutic effects for Rheumatoid arthritis (RA). Nanoparticles have beenwidely investigated for rheumatoid arthritis (RA). Though, higher doses of Nanocarriers also increase the incidence of dreadful adverse effects. Wherever, nanocarrier properties are most populated by the use of different approaches like targeting ligands, to change the physicochemical properties including higher encapsulation, better penetrating ability in cells etc. The main advantage of the nanocarrier that they provide longer circulation which enhances drug localization at the inflamed site and selective targeting to enhance the therapeutic index of anti-arthritic drugs. However, the optimal properties of nanocarrier also depend on the route of administration and size of particles, thus larger size show more retention upon local injection and smaller sized ones are more optimal for passive targeting. The present article discusses the emergence of nano-carriers for antirheumatic drugs, which delivers drug molecule to the inflamed site by topical, intra-articular (i.a) and intra-venous (i.v) administration to take advantage of therapeutic efficacy by passive and active drug delivery. Advancements have been made extensively but still better investigations are needed to achieve the risk-benefit ratio for the development of safe, stable and effective targeting nanocarriers for the e treatment of rheumatoid arthritis (RA).

Liquid isoprene rubber as a safe processing aid in natural rubber compounds

In order to overcome the carcinogenic ‘polycyclic aromatic hydrocarbon’ emission from aromatic oils, which are restricted in European countries since 2010, various efforts have been made to replace the aromatic oil in rubber-based compounds either fully or partially. The authors in the present work have used liquid isoprene rubber (LIR50 or LIR) as a reactive plasticizer in natural rubber (NR) compound at different loadings (2, 4, 6 and 8 phr) and have studied its effect on viscosity, curing characteristics and physico-mechanical properties. These results were compared with the control compound containing conventional aromatic oil as plasticizer. From the experimental data, it was noticed that, the minimum torque for control compound was 0.33 dNm and that for LIR based compounds ranged between 0.16 to 0.56 dNm. The LIR based compounds exhibited slightly higher Mooney viscosity but offers the same scorch safety. The study supports the utility of LIR as a promising alternative, as revealed by the comparable rheological and physico-mechanical properties attained with the usage of appropriate quantity of LIR, unlike the other alternatives of the previous investigations that usually showed a property difference. Keywords: aromatic oil, liquid rubber, reactive plasticizer, safe processing oil.

Alpha-numeric analysis of engineers cum arbitrators - numerology

ABSTRACT “Numbers are the highest degree of knowledge. It is knowledge itself.”- Plato “The world is built on the power of numbers.” Pythagoras “Everything around you is numbers.” Shakuntala Devi. The date, we were born on, was not an accident. Each number in our date of birth is connected with certain energies and vibrations. Similarly, each and every letter in our name (first as well as full name) also has particular frequency, energies and vibrations. The combined and correlated energies of numbers and letters of an individual reveal about the past, present and future. The careful study of these universal divine energies can reveal, who you are, why you are here, where are you going and how will you get there. In other words what is your personality, nature, thinking, and what is your future in terms of family career relationships and finances etc. In this study, an attempt has been made to analyze -How certain patterns of name numbers and date of birth related core numbers can emerge as a directional guide for an individual to choose any specific career/profession (by studying the patterns of over 1100+ date of births and names of the Engineers cum Arbitrators).

Analgesic and anti-inflammatory activities of fixed oil of macrotyloma uniflorum (lam.) verdc. in mice and rats

Macrotyloma uniflorum, commonly known as horse gram or kulthi bean, is grown as a pulse for livestock and human consumption. The beans contain about 1.3% fat, 18% protein, 15% carbohydrate, and vitamins and minerals. Traditional medicine uses it as an antihyperglycemic, antioxidant, antihypertensive and diuretic. Other important medicinal uses include the treatment of renal stones, obesity, piles, oedema and fever. The present study evaluated analgesic (by acetic acid-induced writhing, hot plate and tail flick tests in mice) and anti-inflammatory (carrageenan-induced paw oedema in rats) activities of Macrotyloma uniflorum fixed oil (MUFO). Four groups were included in the study: Group I: Normal Saline Control (2ml/kg), Group II: MUFO (2ml/kg), Group III: MUFO (4ml/kg), and Group IV: Standard Acetyl salicylic acid (ASA 300mg/kg). All results were significant; however, the tail flick and paw oedema tests observed a delayed onset of action. The oil's acute oral toxicity was also checked in mice and was found safe up to a 4ml/kg dose, as no signs of toxicity and mortality were observed. It is concluded that Macrotyloma uniflorum fixed oil may possess analgesic and anti-inflammatory activity, which can be related to a peripheral mechanism of action.

Efficient detection of escherichia coli o157:h7 using a reusable microfluidic chip embedded with antimicrobial peptide-labeled beads

The ability of antimicrobial peptides (AMPs) for effective binding to multiple target microbes has drawn lots of attention as an alternative to antibodies for detecting whole bacteria. We investigated pathogenic Escherichia coli (E. coli) detection by applying a microfluidic based biosensing device embedded with AMP-labeled beads. According to a new channel design, our device is reusable by the repeated operation of detection and regeneration modes, and the binding rate is more enhanced due to even distribution of the bacterial suspension inside the chamber by implementing influx side channels. We observed higher binding affinity of pathogenic E. coli O157:H7 for AMP-labeled beads than nonpathogenic E. coli DH5α, and the fluorescence intensity of pathogenic E. coli was about 3.4 times higher than the nonpathogenic one. The flow rate of bacterial suspension should be applied above a certain level for stronger binding and rapid detection by attaining a saturation level of detection within a short time of less than 20 min. A possible improvement in the limit of detection in the level of 10 cells per mL for E. coli O157:H7 implies that the AMP-labeled beads have high potential for the sensitive detection of pathogenic E. coli at an appropriate flow rate.

Comparison of oxygenation and ventilation parameters between proseal laryngeal mask airway and endotracheal tube in patients undergoing laparoscopic surgeries: a prospective observational study

Introduction: Use of endotracheal tube (ETT) has many limitations. There is a need for an airway device with similar safety and good side effect profile. In this prospective observational study, the oxygenation and ventilation parameters between patients who were inserted Proseal laryngeal mask airway (PLMA) or ETT for laparoscopic surgeries were compared. Materials and Methods: After ethical committee approval, informed consent was obtained from sixty patients (thirty in each group) posted for elective laparoscopic surgery. Following induction of general anaesthesia and paralysis, PLMA or ETT was inserted and pressure control mode was used for ventilation. The following parameters were measured: a. Oxygen saturation and changes in FiO2 needed to ensure a target SpO2> 95%, EtCO2 and changes in respiratory rate and inspiratory pressure needed to ensure a target EtCO2 between 35-45 mmHg. b. Insertion characteristics of airway device and gastric tube, hemodynamic responses, incidence of complications. Statistical Analysis: Chi-square test was used to analyze qualitative data. Independent t test was used to assess quantitative variables. Repeated measures ANOVA was used to compare the outcome measures over time adjusted for duration of surgery and anaesthesia. P values<0> Results: Both groups were comparable with respect to age, gender and weight. Oxygenation and ventilation parameters achieved with both ETT and PLMA were comparable and satisfactory. Haemodynamic parameters increased significantly in ETT group compared to PLMA group during airway insertion and removal. Also, postoperative sore throat was comparatively less in the PLMA group. Conclusion: Hence we conclude that PLMA may be considered as an alternative to ETT in airway management of patients undergoing laparoscopic surgeries with comparable oxygenation and ventilation parameters and improved side effect profile.

A systematic approach on reducing the energy consumption in green computing

Green computing is focusing on reducing the energy consumption, resource usage, carbon dioxide emission. It was found that Last year, Google used about 12.4 terawatt-hours of electricity. Energy consumption in data centers is reduced by decreasing the resource utilization that is by switching off or shifting the computing nodes to sleep mode. But when the servers are being used the energy consumption is minimized by using energy efficient scheduling and optimization techniques.In WNS the sensor nodes are deployed in remote areas, these sensors are powered by battery that decreases the lifetime, therefore by using energy efficient techniques can increase the uptime of the battery-operated devices in WNS. This work studied various energy efficient techniques that minimize energy consumption usage in Data Centers (DC) and the algorithms that increase the uptime of the battery-operated device in (WNS) Wireless Network Sensors.

Bioefficacy and persistency of insecticides against blister beetle, mylabris pustulata (thunb.) in pigeonpea, cajanus -cajan (l.) millsp

Blister beetle, Mylabris pustulata (Thunb.) is a polyphagous pest attacking flowers of pigeonpea (Cajanus cajan), cotton (Gossypium sp), lady’s finger (Abelmoschus esculentus), mungbean (Vigna radiata), urdbean (Vigna mungo), ricebean (Vigna umbellata) etc. throughout the country. Because of its polyphagous feeding nature and hard protective adaptation against insecticides, long term management of this pest with a single molecule is difficult. Therefore, field cum laboratory experiments were carried out for three consecutive cropping seasons during kharif 2008-09, 2009-10 and 2010-11 to find out the persistence and efficacy of different insecticides. It was found that decamethrin 2.8EC was 3334 times toxic with lowest LC50 value (0.0000563) followed by monocrotophos 36SL as compared with endosulfan which was the least toxic with LC50 value (0.1877). Insecticides evaluated for their persistent toxicity during 2009-10 revealed that decamethrin and thiodicarb caused cent per cent mortality of adult blister beetle immediately after spray. At 8th days after spraying, decamethrin caused 60 per cent mortality. Insecticides evaluated for their efficacy during the year 2010-11 revealed that the plants were found free from adult blister beetle population in treatments involving decamethrin and cypermethrin even at ten days after spray. Among all the treatments, spraying of thiodicarb 75WP @ 625 g ha-1 provided the highest grain yield (18.87 q ha-1). Maximum cost-benefit ratio was observed in monocrotophos 36SL, cypermethrin 25EC and decamethrin 2.8EC

A comparative study of garlic antibacterial activity

This comparative study was conducted between local (Libyan) and imported (Chinese) garlic to evaluate their antibacterial activity against some isolated gram-positive and gram-negative bacteria. The study was carried out by using the agar well diffusion method at different aqueous extract concentrations (25%, 50%, 75% and 100%). The results showed that distinct antibacterial effects on both types of garlic with some differences between local and imported garlic. However, the zone of inhibition was more against Staphylococcus aureus, Klebsiella pneumonia and Escherichia coli, respectively. Furthermore, the antibacterial activity increased with the increase of concentration. So, this study recommends that garlic should be used against bacterial infection and more studies may be done against other bacterial species, especially multidrug-resistance strains.

Determinants of intention to improve oral hygiene behavior among students based on the theory of planned behavior: a structural equation modelling analysis

Introduction: The prevalence of oral hygiene behaviors (OHB) is very low among school children in Ethiopia. However, the determinants of student's readiness/intention to perform those behaviors have been remained unstudied. Objective: This study aimed to identify the determinants of oral hygiene behavioral intention (OHBI) among preparatory school students based on the theory of planned behavior (TPB). Methods and materials: An institution-based cross-sectional study was conducted among 393 students. A 98-item self-administered questionnaire was used to evaluate oral hygiene knowledge (OHK), oral hygiene behavior (OHB), and OHBI based on TPB variables [attitude (ATT), subjective norms (SN) and perceived behavioral control (PBC)]. Descriptive statistics and structural equation modeling analysis (SEM) were employed to confirm relationships and associations among study variables. A p-value of less than 0.05 and a 95% confidence interval were used to declare statistical significance. Results: A total of 393 students were participated with a response rate of 97.5%. The mean age of the participants (54% females) was 18 (± 1.3) with an age range of 16 to 24. The TPB model was well fitted to the data and explained 66% of the variance in intention. ATT (β = 0.38; 95% CI, (0.21, 0.64)), SN (β = 0.33; 95% CI, (0.05, 0.83)) and PBC (β = 0.29; 95% CI, (0.13, 0.64)) were significant predictors of OHBI, where ATT was the strongest predictor of OHBI. Conclusion: The TPB model explained a large variance in the intention of students to improve their OHB. All TPB variables were significantly and positively linked to stronger intent, as the theory suggests. Furthermore, these results suggest that the model could provide a framework for oral hygiene promotion interventions in the study area. Indeed, these interventions should focus on changing the attitudes of students towards OHB, creation of positive social pressure, and enabling students to control OHB barriers.

A deep learning approach visual recognition of bird species in noisy environments

In this paper, we propose a deep learning approach for visual recognition of bird species in noisy environments. Bird species recognition has been a challenging task due to the high variation in bird appearances and the presence of noise and clutter in natural environments. Our approach utilizes a deep convolutional neural network (CNN) to learn discriminative features from bird images and classify them into different species. We also incorporate data augmentation techniques to increase the diversity of the training data and improve the robustness of the model. To address the issue of noisy environments, we introduce a novel noise-robust loss function that penalizes the model for incorrect predictions caused by noise. We evaluate our approach on a dataset of bird images collected from diverse environments and compare it with state-of-the-art methods. Our results demonstrate that our approach achieves superior performance in both clean and noisy environments, highlighting the effectiveness of our noise-robust loss function. Our approach has the potential to be applied in real world scenarios for bird species recognition and conservation.
