Measurement of Viscosity of High Alumina Blast Furnace Slags by Statistical Approach

Slag viscosity is an important process variable of the blast furnace process. The viscosity of molten slag is dependent basically on its chemical composition and on its temperature. Indian blast furnaces run into high alumina slag (Al2O3 >= 25%) due to high alumina/silica ratio in iron ore as well as sinter and high ash content in the coke. These slags are highly viscous which affects the gas permeability, heat transfer etc. In the present work slag viscosity was determined for CaO-SiO2-MgO-Al2O3 quaternary system using Iida model. Slag composition consists of MgO values between 4 and 10%, CaO/SiO2 between 0.9 to 1.2 and Al2O3 25%. The temperature range was between 1523 and 1723K which covers the liquidus temperature because the viscosity at this temperature will fluctuate greatly. The effect of CaO/SiO2, MgO and temperature on viscosity were studied. The results indicate that the viscosity decreases with increase in basicity and MgO content

Large Scale Generative Multimodal Attribute Extraction for E-commerce Attributes

E-commerce websites (e.g. Amazon) have a plethora of structured and unstructured information (text and images) present on the product pages. Sellers often either don't label or mislabel values of the attributes (e.g. color, size etc.) for their products. Automatically identifying these attribute values from an eCommerce product page that contains both text and images is a challenging task, especially when the attribute value is not explicitly mentioned in the catalog. In this paper, we present a scalable solution for this problem where we pose attribute extraction problem as a question-answering task, which we solve using \textbf{MXT}, consisting of three key components: (i) \textbf{M}AG (Multimodal Adaptation Gate), (ii) \textbf{X}ception network, and (iii) \textbf{T}5 encoder-decoder. Our system consists of a generative model that \emph{generates} attribute-values for a given product by using both textual and visual characteristics (e.g. images) of the product. We show that our system is capable of handling zero-shot attribute prediction (when attribute value is not seen in training data) and value-absent prediction (when attribute value is not mentioned in the text) which are missing in traditional classification-based and NER-based models respectively. We have trained our models using distant supervision, removing dependency on human labeling, thus making them practical for real-world applications. With this framework, we are able to train a single model for 1000s of (product-type, attribute) pairs, thus reducing the overhead of training and maintaining separate models. Extensive experiments on two real world datasets show that our framework improves the absolute recall@90P by 10.16\% and 6.9\% from the existing state of the art models. In a popular e-commerce store, we have deployed our models for 1000s of (product-type, attribute) pairs.Comment: ACL 2023 Industry Track, 8 Page

An unusual presentation of oral myiasis in maxilla: A case report

Myiasis is a universal term for infection by the parasitic fly larvae that feed on their host, which can be either living or dead tissue. Oral myiasis is still “rare” and “unique” due to the fact that oral cavity rarely provides the necessary habitat conducive for a larval lifecycle. In humans, the most commonly affected sites are the nose, eyes, skin wounds, sinuses, lungs, ears, gut, gallbladder, vagina, nasal cavities, and rarely the mouth. Here, we report a case of oral myiasis in an 83-year-old female patient reporting with swelling in the maxillary anterior region with the movement of bugs inside the mouth since 2–3 days. Treatment of myiasis has been discussed in the case report

Evaluation of relationship between microbial load and drug efficacy of Andrographis paniculata during storage

Three different extracts of Andrographis paniculata obtained by using three different solvents i.e. acetone, ethanol and water, were used to find out correlation of antimicrobial potency of the drug among them and with storage period of six months. Antibacterial activities were assessed by well diffusion method against Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, Bacillus subtilis, and Salmonella typhi and antifungal activity by food poisoning technique against Candida albicans. No definite pattern of antimicrobial nature in acetone, ethanol and aqueous extract could be observed. Acetone extract showed maximum inhibitory (18.3mm) effect among all extract in general. Ethanol extract could attain second position and aqueous extract failed to inhibit growth of any organism even at 100% concentration. A declined trend of inhibitory effect of extract with increased number of storage days has been found showing a negative relation between inhibitory effect of the drug and storage duration. But positive correlation between inhibitory effect and concentration has been recorded. No inhibition was recorded against E. coli by any of the extract Bacterial load in term of CFU/g was found tremendously enhanced with increase of storage period. Negative correlation between microbial load and drug efficacy had been established while positive correlation between microbial load and storage period had been recorded

Dental management of a patient with down syndrome: a case report and review of literature

Down syndrome (DS) is the most common chromosomal abnormality which affects numerous organs, including the orofacial region. Patients with DS may not be cooperative during dental treatment, and in cases of complex treatment, it is necessary to use oral or inhaled sedation and/or general anesthesia, which represents safe and efficient treatment resources. This article reports a management of DS in a 7-year-old male patient who came to the Hospital of New Delhi with the chief complaint of pain in lower right back tooth region. Due to the uncooperative nature of the patient, dental treatment was done under general anesthesia in which multiple dental restoration and extraction were done

Glycaemic and weight-loss outcomes of graded doses of canagliflozin in type 2 diabetes — a real-world study

Background. Costs are the most important cause of therapeutic non-compliance. Half canagliflozin (CANA)–300 tablet has lowest cost/mg among all CANA preparations; data are unavailable on efficacy of half CANA-300. This study evaluated weight loss and glycaemic outcomes of 100 mg versus 150 mg versus 300 mg of canagliflozin as part of standard therapy.Methods. Data, retrospectively captured from medical records of two centres in Delhi for patients > 35 years with type-2 diabetes (T2DM), and on canagliflozin, having > 6 months follow-up, were analysed. Patients were in 3-groups depending on canagliflozin dosage: Group 1 on canagliflozin 100 mg/day (1 tablet CANA-100), Group-2 on canagliflozin 150 mg/day (half tablet CANA-300), and Group 3 on canagliflozin 300 mg/day (1 tablet CANA-300). Primary endpoints were glycaemicefficacy and weight-loss.Results. From 3,569 records evaluated, 1,232 people with T2DM on canagliflozin were screened; data from 528 individuals analysed (257, 138 and 133 in Groups: 1, 2 and 3 respectively). People in all three groups were comparable with regards to sex, T2DM duration, glycated haemoglobin (HbA1c), haemoglobin, creatinine, lipids, albuminuria and medications. Group-2 patients were youngest and had highest BMI. Following 6-months, both absolute and percent weight-loss was significantly higher in Group-2 (–3.5 kg [–6.60–0.00]; –3.62%), followed by Group-3 (–3.0 kg [–5.3 to –0.8]; –3.33%), and lowest in Group-1 (–1.05 kg [–2.85 to –0.17]; –1.31%) (P = 0.002 and 0.014, respectively). Glycaemic efficacy was comparable among groups.Conclusion. Half CANA-300 tablet has comparable glycaemic efficacy and weight-loss compared to single CANA-300 tablet, but superior weight-loss compared to CANA-100

Operation of Circuit Breaker with the help of Password

A circuit breaker is an electrical switch use to protect an electrical circuit from damage caused by faults. Its basic function is to detect a fault condition and protect from it. Fuse operates once after that it must be replaced but a circuit breaker can be reset to resume normal condition. During the manual operation, we see inoperable electrical accidents to the line man are rises during maintenance due to improper communication between the maintenance staff and the substation staff. In order to prevent such accidents, password based circuit breaker is design so that only authentic person can operate it with a password. There is also a facility of changing the password. The system is fully controlled by the microcontroller. The password is saved in an EEPROM, interfaced to the microcontroller and the password can be changed any time. A keypad is used to submit the password and a relay to operate circuit breaker, which is indicated by a bulb. Any wrong attempt to open the circuit breaker by entering the wrong password an alert will be shown in the LCD

Coping with Illness: Insight from the Bhagavad Gita

The Shrimad Bhagavad Gita enlightens everyone on how to cope up with various situations in life. It uses the conversation between Lord Krishna and Arjuna to highlight initial negative coping mechanisms exhibited by the latter. It goes on to showcase positive coping skills suggested by Lord Krishna and implemented by Arjuna. The Bhagavad Gita, through this case-based methodology, teaches us how to cope with a demanding situation. Diabetes is a lifestyle disease, which warrants a thorough change in one\u27s lifestyle, including changes in basic activities such as diet and exercise. This brief communication utilizes the teachings of Bhagavad Gita to help in coping with illness, especially chronic illness such as diabetes. The article cites verses from the Bhagavad Gita to show how one may cope with the stress of illness such as diabetes

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely
