Effects of Fruit Bagging Treatment with Different Types of Bags on the Contents of Phenolics and Monoterpenes in Muscat-Flavored Table Grapes

The effects of fruit bagging treatments with seven different types of bags on the physicochemical characteristics of three table grape cultivars: RuiduZaohong (RDZH), RuiduHongyu (RDHY), and RuiduHongmei (RDHM) were investigated. Headspace-solid-phase micro-extraction combined with gas chromatography mass spectrometry (HS-SPME-GC-MS) was used to determine the compositions of monoterpenes in the fruit. The results showed that the total soluble solids in RDZH and RDHY fruits treated with the transparent, mesh, yellow, white, and blue bags were significantly higher than the control. The sugar–acid ratio of RDZH was optimized under the transparent bag and yellow bag treatments, and both significantly increased the sugar-acid ratio of RDHY and RDHM. Additionally, mesh bag, transparent bag, and white bag improved the contents of phenolics to a certain extent. The most abundant volatiles were linalool, geraniol, β-myrcene, β-cis-ocimene, and β-trans-ocimene, of which linalool was the main aroma component. The least squares discriminant analysis results showed that linalool, 4-terpineol, and terpinolen could be used to distinguish the main contribution of different bagging treatments for RDZH. Trans-isogeraniol, α-terpineol, and terpinolen could be used for RDHY. Trans-isogeraniol, β-myrcene, and terpinolen could be used for RDHM. In conclusion, transparent and white bags promoted the accumulation of phenolics and monoterpenes while pink and blue bags showed inhibitory effects.

KNOWLEDGE AND AWARENESS ON MANAGEMENT OF BIOMEDICAL WASTE AMONG ORTHODONTISTS AND GENERAL DENTAL PRACTITIONERS

Background: Dental care facilities generate a high amount of Biomedical Waste (BMW) like sharps such as surgical needles, blades, wires, brackets, extracted teeth, human tissues, discarded or expired medicines and dental materials, highly contaminated with blood and saliva. Segregation and collection should be done in separate colour coded bags or containers; according to Biomedical Waste Rules, 2016 the Ministry of Environment and Forest in India. Poor management of wastes leads to high risk to public, patients and professionals and also contributes to environmental degradation. Aim: To assess the knowledge and awareness on management of biomedical waste management among orthodontists and practicing general dentists. Materials and methods: A cross sectional study was conducted through Google form (electronic based survey) among general practising dentists; survey consisted of 18 closed ended questions. The data collected were tabulated in Microsoft Excel and exported to SPSS, descriptive statistics and Chi-Square test was performed (p < 0.05 was considered statistically significant). Results: 83.8% practising dentists follow the biomedical waste disposal policy in their hospital or clinic, among which 91% use protective barriers (e.g. gloves, masks) during handling of biomedical waste. 63.1% disposed human anatomical waste and blood contaminated waste properly where only 55.9% disposed extracted teeth and human tissue in yellow bags. Significant association was found between management of incinerated ash and qualification among orthodontists ( p=0.019) and with experience of less than 1 year had proper knowledge; (p=0.021). Disposal of plaster of Paris was properly managed among general practioners (p=0.039). Management of sharps was done properly using needle destroyers among general dentists and orthodontists (p=0.041). Conclusion: Safe and effective management of biomedical waste is a legal necessity but also a social responsibility of dentists, according to this present survey 7 – 9.2 % of the dentists are not effectively following the biomedical waste management.

The Sensitivity of some Types of Citrus Fruits, the role of the Propolis and the Color of Storage Bags in the Development of Green Mold Caused by Fungi Penicillium Digitatium

The results of the study indicated that green mold caused by Penicillium digitatium was noticed in all typesof citrus fruits (orange, mandarin, bitter orange, lemon). The most sensitive among these fruits was themandarin with 56.12% infection, followed by orange with 40.18%. On the other hand, the bitter orangeand the lemon showed more resistant to the disease, and the their infection percentages were (32.14% and30.55% respectively. The results indicated that the color of the bags had a great effect on the developmentof the disease where the infection percentages when using light green bags and light yellow bags were(19.68%, 17.24%) respectively. While for the dark black bags, the infection percentage was 13.73%. The useof porpolis in all concentrations (6, 8, 10, 12) g/l did not lessen the size of the infected area compared withcontaminated treatment by pathogen.

A theoretical study on the mass input and output and energy of the biomedical waste incinerator

Medical waste production has increased with many government and private hospitals and health centres due to the increase in the population, especially in the spread of Coronavirus Covid-19. This increase in medical waste is treating in medical incinerators. One of the advantages of incineration is the reduction of volume, weight and energy recovery. This paper examines the medical waste incinerator of one of the Medical City hospitals in Baghdad, as this incinerator internally divided into primary and secondary chambers. The medical waste for yellow bags placed in the primary chamber is burned with the help of air and a burner of 178-356 kW, resulting in waste burned. Then the combustion products pass through the secondary chamber, wherewith air and another burner of 178-356 kW, the combustion of gases and volatile materials from the waste completed. Air is then supplied to the flue gases to dilute the emission concentrations and reduce the flue gas temperature. This paper presents a study on the inputs and outputs of waste, air, fuel and the advantage of the heat quantity generated from the combustion of biomedical waste. As a result of this theoretical work, this incinerator provides an acceptable and durable solution to waste disposal problems and the risks of spreading viruses today.

Risk and Opportunity of Using Plastics from Waste Collected in a Yellow Bag.

The article presents the results of research aimed at analysing the share of fractions suitable for recycling and pollutants in waste collected in a yellow bag. The research was carried out in an area inhabited by 200,000 people. The amount of waste collected in the communes in yellow containers in 2016–2019 increased systematically in communes: rural by 75.8, urban–rural by 44.9 and urban by 17.8%. The collection efficiency expressed in the degree of collection was the highest and grew fastest in rural areas (from 25.1 to 35.5%). In cities, it practically did not change (14.4–15.8%). The weight of recyclable components represented on average 39.9% of the weight of yellow bag waste. Plastic bottles (PET) packaging prevailed, the share of which changed from 19.6 to 14.8%, including the share of colourless PET decreasing from 7.9 to 5.8%. At present, revenue from the sale of secondary raw materials obtained from waste collected separately to yellow bags covers only 26% of the costs related to the recycling and recovery of waste delivered to the installation. Support for separate collection of plastics through recovery organisations, i.e., entrepreneurs who are obliged to recover and recycle waste, is symbolic.

Effects of bagging or the combination of umbrella and bag treatments on anthocyanin accumulation in the berry skin of ‘Kyoho’ (Vitis labruscana) Grape

The object of this study was to investigate the influence of bagging or the combination of umbrella and bags on berry composition, especially anthocyanin accumulation, in ‘Kyoho’ (V. labruscana) berry skins. Five different colors and bag materials commonly used in production were chosen for this study: white, green, yellow, nonwoven and transparent, and the umbrellas were made of plastic material. The composition and content of anthocyanins in the berry skin of ‘Kyoho’ were analyzed by HPLC-MS. The results showed that bagging or a combination of umbrella and bags on anthocyanin concentration in ‘Kyoho’ grapes showed inconsistent effects that depended on the colors and materials of the bags and the use of an umbrella or not. Compared with the control, the inhibition effects of white, green and yellow bags on the soluble solids content and the total and individual anthocyanin concentrations in ‘Kyoho’ grapes reached significant levels; effects of green and yellow bags were the most significant among them. The plastic umbrella used in this study also presented a lower relative light intensity and produced more even-colored clusters. White, green, and yellow bags and combinations of umbrella and bags significantly increased some stable anthocyanin proportions to varying degrees, such as coumaroylated and methylated anthocyanins, compared to the control.

Effect of bagging colour on fruit quality of wax apple (Syzygium samarangense (Blume) Merr. & Perry) ‘Thabthimchan’

Wax apple is one of the important fruit crops of Thailand. The major problems of wax apple production in Thailand are fruit flies and birds. Farmers have to bag the fruit after fruit set with a white plastic bag to prevent fruit flies, but the white plastic bag cannot protect the fruit from birds. Six wax apple trees, 15 years old, were selected for the experiment. The fruit of each tree was bagged with 10 bags each of white, yellow, green, blue, red and black plastic bags. A total of 360 bags were used. The quality of fruit was recorded after harvest. The results showed that the width, length, weight, volume of fruit, TSS, TA, and TSS/TA were different among different treatments. The mean weights of the fruit were 145.52, 142.62, 140.70, 139.30, 137.43 and 126.42 g in the white, red, yellow, green, blue and black bagged groups, respectively. The TSS were 9.96, 9.73, 9.55, 9.53, 9.38 and 9.38 °Brix in the white, yellow, red, blue, green and black bagged groups, respectively. In conclusion, we recommend that red and yellow plastic bags can be used for bagging wax apples while the black colour is not recommended.

A case study to review compliance to biomedical waste management rules in a tertiary care hospital

Background: Every healthcare establishment is known to produce several tonnes of waste. Over a period of time to cater to the needs and demands of the growing population has resulted in rapid mushrooming of hospitals, both in the government and private sector. Improper management of waste generated in health care facilities causes a direct health impact on the community, the health care workers and the environment. Such waste requires management & specific treatment prior to its final disposal. The objectives were to observe compliance of protocols in handling, transport & storage of Biomedical Waste in a tertiary care hospital and to assess compliance to occupational safety measures used by the health care staff.Methods: A validated checklist with 41 parameters to check compliance to various functions carried out at source of generation, handling, transport & storage by a Health Care Worker for BMW management was prepared. It was an observational study that made use of complete enumeration method to select all study sites. A total of 67 sites were visited and observed. A total of 4 visits were made to each area to assess the compliance to rules.Results: Out of 64 wards that were observed for compliance to BMW handling and Management rule 2011, 42.18% disinfected the biomedical waste bins daily. Mixing of contents in the red bag, yellow bag and black bag was found to be 20.31%, 12.5% and 10.93% respectively. None of the wards observed cutting of gloves and saline bottles prior to disposal.Conclusions: The tertiary care hospital where the study was carried out was compliant with most rules with respect to BMW management. Segregation, mutilation and disinfection practices were not performed strictly at all waste generating sites. Due to patient overload and lack of staffing mutilation and disinfection practices were overlooked at many sites. Day to day collection of waste from all sites was not carried out due to which record books were not properly maintained. False reporting was noted on records at various sites.

A study on assessment of knowledge on biomedical waste management among health care workers of Malabar Medical College Teaching Hospital, Calicut, Kerala, India

Background: Health care institutions and hospitals generate biomedical waste which can introduce various infections and injuries to the healthcare workers, patients and harm the surrounding environment. For proper management of biomedical waste Government of India has introduced the biomedical waste management and Handling rules in 1998, unfortunately health care workers awareness regarding biomedical waste segregation, handling and management is minimal hence, the study addresses the issues related to it. Methods: This cross sectional study was conducted in the month of July 2016 among health care workers at Malabar Medical College Hospital and Research Centre, Calicut, India. A pre-tested, semi-structured questionnaire was used to elicit the various information like collection, segregation and disposal of biomedical waste. Results: 567 health care workers were interviewed.44.3% (251) opined correctly that biomedical waste should not be kept more than 48 hours at hospital settings. 61.6% (349) opined waste sharps should be disposed in white/blue puncture proof containers.89.6% (508) knew about HIV, hepatitis B and hepatitis C are common infections transmitted due to improper biomedical waste management. 60.5% (345) and 61% (346) opined that human anatomical waste and pads, cottons, dressings should be disposed in yellow bags, respectively. 70.7% (401) were fully immunised against hepatitis B. 29.8% (169) had received training on biomedical waste management. Conclusions: Knowledge regarding biomedical waste disposal among nursing staff is satisfactory compared to other health care workers, adequate training among health care workers can improve the biomedical waste management and handling practices at hospital settings.

A Direct Comparison of N400 Effects of Predictability and Incongruity in Adjective-Noun Combination

Previous work has shown that the N400 ERP component is elicited by all words, whether presented in isolation or in structured contexts, and that its amplitude is modulated by semantic association and contextual predictability. What is less clear is the extent to which the N400 response is modulated by semantic incongruity when predictability is held constant. In the current study we examine N400 modulation associated with independent manipulations of predictability and congruity in an adjective-noun paradigm that allows us to precisely control predictability through corpus counts. Our results demonstrate small N400 effects of semantic congruity (yellow bag vs. innocent bag), and much more robust N400 effects of predictability (runny nose vs. dainty nose) under the same conditions. These data argue against unitary N400 theories according to which N400 effects of both predictability and incongruity reflect a common process such as degree of integration difficulty, as large N400 effects of predictability were observed in the absence of large N400 effects of incongruity. However, the data are consistent with some versions of unitary ‘facilitated access’ N400 theories, as well as multiple-generator accounts according to which the N400 can be independently modulated by facilitated conceptual/lexical access (as with predictability) and integration difficulty (as with incongruity, perhaps to a greater extent in full sentential contexts).

Bio-Medical Waste Managment in a Tertiary Care Hospital: An Overview.

Bio-Medical Waste (BMW) management is of utmost importance as its improper management poses serious threat to health care workers, waste handlers, patients, care givers, community and finally the environment. Simultaneously, the health care providers should know the quantity of waste generated in their facility and try to reduce the waste generation in day-to-day work because lesser amount of BMW means a lesser burden on waste disposal work and cost saving. To have an overview of management of BMW in a tertiary care teaching hospital so that effective interventions and implementations can be carried out for better outcome. The observational study was carried out over a period of five months from January 2016 to May 2016 in Chhatrapati Shivaji Subharti Hospital, Meerut by the Infection Control Team (ICT). Assessment of knowledge was carried out by asking set of questions individually and practice regarding awareness of BMW Management among the Health Care Personnel (HCP) was carried out by direct observation in the workplace. Further, the total BMW generated from the present setup in kilogram per bed per day was calculated by dividing the mean waste generated per day by the number of occupied beds. Segregation of BMW was being done at the site of generation in almost all the areas of the hospital in color coded polythene bags as per the hospital protocol. The different types of waste being collected were infectious solid waste in red bag, soiled infectious waste in yellow bag and sharp waste in puncture proof container and blue bag. Though awareness (knowledge) about segregation of BMW was seen in 90% of the HCP, 30%-35% did not practice. Out of the total waste generated (57912 kg.), 8686.8 kg. (15%) was infectious waste. Average infectious waste generated was 0.341 Kg per bed per day. The transport, treatment and disposal of each collected waste were outsourced and carried out by 'Synergy' waste management Pvt. Ltd. The practice of BMW Management was lacking in 30-35% HCP which may lead to mixing of the 15% infectious waste with the remaining non-infectious. Therefore, training courses and awareness programs about BMW management will be carried out every month targeting smaller groups.

Effect of Pre-Harvest Bagging on Fruit Quality of Litchi(Litchi ChinensisSonn) CV. Rose Scented

An experiment on pre-harvest bagging of litchi fruits was conducted at Department of Horticulture Govind Ballabh Pant University of Agriculture and Technology, Pantnagar. Litchi fruits cv. Rose Scented were bagged by perforated transparent polyethylene bag, green polyethylene bag, white polyethylene bag, yellow polyethylene bag, black polyethylene bag, blue polyethylene bag, butter paper bag and brown paper bag, whereas, non-bagged fruit was used as control. Fruits were bagged two months prior to harvest. Bagged and non-bagged (control) fruits were harvested at commercial maturity. After harvest, postharvest quality characteristics were determined such as, fruit Retention, fruit cracking, pericarp sun-burn, weight and size of whole fruit, total soluble solids (TSS), titratable acidity, ascorbic acid, sugar content and sensory evaluation. Results showed that brown paper bag and butter paper bag were found effective in increasing days to maturity, fruit retention, reducing fruit cracking, pericarp sun-burn as well as showed maximum fruit weight and size. Minimum acidity (0.51%) while TSS (19.5o B), ascorbic acid (21.56 mg/100gm), reducing sugar (11.31%) and total sugar (13.13%) were found maximum in fruits bagged in green polyethylene bag. Hence, brown and butter paper bags and green polyethylene bag were found effecive in improving fruit colour and maintaining fruit quality at harvest.

Clinical management and gross pathological findings of a severe anaplamosis in a dairy cow

Objectives: Bovine anaplasmosis is an arthropod-borne hemolytic disease of cattle which is caused by a rickettsia; Anaplasma marginale . Anaplasmosis is also called Yellow bag or yellow fever, where the affected animals usually develop a jaundiced appearance. The objective of this study was to investigate the clinical findings, treatment and gross pathology of a severe anaplasmosis in a dairy cow. Materials and methods: In this report, a rare case of fatal anaplasmosis in a 4 year old Jersey-Friesian cow, weighing about 200 kg was reported. Diagnosis was done based on clinical symptoms, blood examination for the presence of A. marginale , and biochemical analyses of blood. Leishman staining was done to check the A. marginale at the margin of erythrocytes. Treatment was instituted with blood transfusion and Oxytetracyline dosed at 20 mg/kg body weight and iron supplement containing 20 mL Cobaphos (containing Phosphorus 125mg + Cyanocobalamine 0.05 mg) and 20 mL Fercobsang containing Iron (as ammonium citrate) 1.75 mg, Cyanocobalamine (Vitamin B12) 0.025 mg, Nicotinamide (vitamin PP) 20 mg, Cobalt (as digluconate) 0.0067 mg, Benzyl Alcohol (E1519) 20.8 mg) were given intramuscularly. Results: The cow did not survive the infection as it eventually died of the disease. Post mortem examination showed gross evidence of splenomegaly, hepatomegaly, distended bile duct and generalized jaundice. Conclusion: Based on the consequence of this case report, preventive vector control, prompt and appropriate treatment and improved management practices are recommended in order to prevent clinical anaplasmosis cases among cattle. http://doi.org/10.5455/javar.2016.c150
