This study aims to determine the isolation and intensity of downy mildew (Peronosclerospora philippinensis) on maize (Zea mays L.) in Maros Regency during the 2022 planting period. This research was carried out on agricultural land in Pucak Village, Tompobulu District, Maros Regency and at the Pest Laboratory. and Diseases of the Indonesian Muslim University and the Hasanuddin University Disease Laboratory. This research was carried out for 3 months, starting from June to August 2022. The materials and tools used were leaves that were attacked by downy mildew, 2% sugar water, methylene blue, aquades, microscopes, scissors, glass objects, masking tape, tissue towels, plastic clips, camera and stationery. This study uses a survey method by direct observation in the field. Downy mildew leaves are taken and then taken to the laboratory to identify the fungus that causes downy mildew. Based on microscopic observations, Peronosclerospora philippinensis species were found with ovoid shape and thin walls. The results of the observation that the intensity of downy mildew in the field in the first month was 20% with the moderate attack intensity category, then in the second month it increased to 70.2% with the severe category and in the third month which was the highest attack intensity with an average of 96.7%. with the puso category which means that of the 30 plants observed, 29 were attacked by downy mildew. The attack intensity which reaches 96.7% can no longer be used as a seed source.

Effect of Two Different Catheter Dressings on Pain, Comfort, and Satisfaction in Chemotherapy Patients: A Randomized Controlled Study.

The incidence of cancer is increasing on a daily basis. Chemotherapy is one of the methods used in cancer treatment. Chemotherapy is administrated through a peripheral venous catheter. During intravenous chemotherapy, the patient may experience pain and his comfort may deteriorate. This study aimed to determine the effect of two different catheter dressings on the patient's comfort, satisfaction, pain level, and nurse satisfaction. A randomized controlled study was designed. Data of the study It was collected between March and June 2022. Participants were patients who were continuing chemotherapy treatment at a university hospital. The sample consisted of 70 (35 + 35) cancer patients. Sociodemographic information form and visual analog scale were used to collect data. There is no difference in the pain level of the masking tape and standard plaster groups. The patient's comfort, satisfaction, and the nurse's use satisfaction were higher in the group where masking tape was used. There is a very strong positive correlation between patient comfort and patient satisfaction in the masking tape group. The effect size of the applied intervention is very weak. (p > .05). Masking tape can be applied safely as a peripheral venous catheter dressing. (p < .05).

A wax chalk and self-heating paper-based analytical device (SH-PAD) for the detection of bisphenol A.

Bisphenol A (BPA) is a synthetic xenoestrogen widely present in the environment, known for its toxicity, endocrine-disrupting nature, carcinogenicity, and mutagenic effects on living organisms. The detection of BPA is essential as it infiltrates the human body through food, water, dust and dermal contact. Conventional methods currently in use are inadequate for on-the-spot detection. Consequently, there is a pressing need to build an all-in-one device that can be quickly fabricated using readily available and cost-effective off-the-shelf materials for the detection of BPA. Firstly, we have leveraged wax chalk for fabricating hydrophobic barriers on paper, which offers a hydrophilic channel resolution of 1.64 mm ± 0.05 mm and also the ability to confine major aqueous solvents without leakage. The fabricated device was used to detect BPA using the Folin-Ciocalteu reagent and sodium carbonate (in the presence of heat). Secondly, we have developed a self-heating paper-based analytical device (SH-PAD) using masking tape, lamination paper and Whatman filter paper. This cost-effective approach (0.017$) is based on an exothermic reaction caused by sodium hydroxide and a small quantity of aluminium in the paper layers and can retain heat adequately for more than 5 minutes, addressing the challenge of external heat sources and enabling effective and rapid colorimetric detection of BPA using the Folin-Ciocalteu reagent and sodium carbonate. Both methods can detect up to 2 μg mL-1 in spiked water samples. This developed method's user-friendliness and cost-effectiveness make it a promising candidate for point-of-care diagnostics or detection, providing testing capabilities in areas with limited resources.

“A Much More Valuable Signature”: Gender, Factory Labor, and the Mythology of Builder-Signed Amplifiers from Fender's “Tweed” Era, 1948–60

AbstractAmplifiers from Fender's so-called Tweed era (1948–60) are among the most valuable instruments in all popular music. Inside most Fender Tweed amplifiers is a piece of masking tape bearing the signature of the worker who hand-wired the amplifier's circuit. Today, collectors have elevated several of Fender's previously unknown Latina employees into legendary figures with near cultlike followings. In the absence of biographical information about these women, however, the contemporary discourse about them is often highly romanticized. In this article, I present novel historical information about Fender's Tweed-era employees to counter the misinformation surrounding them and Fender's mid-century Fullerton, California factory system more broadly. Analyzing contemporary discourses surrounding Fender's earliest employees, I also critique the persistence of gendered and racialized stereotypes about Fender's female employees being naturally equipped for labor-intensive assembly work due to their supposedly “nimble fingers.” This article also details the social processes through which Fender's Tweed amplifiers have been made “vintage,” and the company's mid-century mass-production techniques have since been attributed the same artisanal values associated with vintage string instrument making. Ultimately, I show how the builder-signatures contained within Fender's Tweed-era amplifiers have been central to the discursive production of value among collectors.

Directional droplet transport behavior on gradient wettability wedge track with extreme wettability contrast

To enhance transport capacity of open-surfaces, a gradient wettability wedge track laid on superhydrophobic background (wedge track No. 2) was fabricated by using masking tape and alkaline-assisted oxidation. The effects of gradient wettability and extreme wettability contrast are emphasized and investigated. The maximum instant velocity of a 10 μL droplet on track No. 2 is ∼ 883.53 mm/s with final transport displacement x = 46.79 mm, which was 64.15 % faster and 11.67 % farther than that on a superhydrophilic wedge track (wedge track No. 1) respectively. Oscillation happens at the wide end of wedge tracks when kinetic energy remains. Oscillation time on wedge track No. 2 is longer, which means gradient wettability can provide an extra driving force. This novel wedge track highlights the necessity of both gradient wettability and extreme wettability contrast and will have broad prospects in directional transport on open-surfaces, biological research, energy conversion and microfluidic mixers.

An evaluation of two adhesive media for the recovery of DNA from latent fingermarks: A preliminary study

Dual recovery of forensic evidence is beneficial for crime scene and evidence processing as it can potentially double the evidential value of a single source, even more so in instances of DNA fingermarks. The use of adhesive liftering media has shown comparable results to swabbing when dealing with trace DNA recovery. Gelatine lifters have displayed the potential to recover DNA from latent fingermarks with minimal alteration to friction ridge detail post application, yet their ability to recover DNA has not fully been explored. The aim of this research was to compare the use of gelatine lifters with more readily available masking tape in their ability to recover cellular material from latent fingermarks. Natural (n = 120) and sebaceous (n = 120) fingermarks were deposited and aged in time frames from fresh, 1-day, 2-day, 1-week, 2-weeks, and 1 month. DiamondTM Nucleic Acid Dye was used as a visualisation method for any DNA containing cellular material. Images of the fingermarks pre and post lifting, and on the lifting media were imaged using the DSC®5 system. The media’s ability to recover cellular material was assessed using fluorescent particle analysis by the employment of the free software ImageJ. Fluorescent particles could be observed on the lifting media post lifting with the use of DiamondTM Dye. Time was not seen to influence the variation in the number of fluorescent particles observed. The use of gelatine lifters was found to have a higher amount of recovered DNA containing cellular material than masking tape. Visualisation of particles on masking tape were inhibited by its porosity and absorption of the dye. Some fingermark detail could be observed in the gelatine lifters. The DSC®5 system was suitable for imaging fingermarks stained with DiamondTM Dye.

Pineapple Field Establishment Using Slips

Slips are side-shoots or fruit with large crowns that grow from buds on the pineapple (Ananas comosus L.) peduncle. The slips are widely used for pineapple vegetative propagation when crowns are left attached to the fruit that is marketed. There is a difference between the two most popular low-acid pineapple hybrids grown worldwide. The ‘Pineapple Research Institute 73-50’ (CO-2, MD-1) slips develop few roots when planted compared with ‘Pineapple Research Institute 73-114’ (MD2). The slow rooting of 73-50 leads to slow field establishment and can extend the crop cycle. Our objective was to determine the cause of this reduced rooting and evaluate treatments to increase the rooting rate. Rooting trials in moist, coarse vermiculite showed that larger slips and green slips with red hues also had a greater number of roots compared with smaller slips and green or yellow slips. Delaying harvesting of the slips after the fruit were harvested also resulted in a greater number of roots. Treatments including components frequently used for rooting cuttings did not significantly increase root numbers. An exception was a tendency for slips treated with potassium nitrate to have greater rooting during some tests. We present data that support the conclusion that the poor root development is associated with the mechanical impedance of the root from the tightly affixed basal leaf bracts. Removal of the lower ten bracts can lead to greater root numbers. When the slip with the bracts removed was tightly wrapped in plastic wrap and masking tape, rooting was reduced. The sizing and selection of slips that are green with a red hue and collected as late as possible after fruit harvest had the best rooting response.

A technique to facilitate impressions in patients with fixed orthodontic appliances

Accurate irreversible hydrocolloid impressions are difficult to obtain in patients undergoing fixed orthodontic treatment. Although various studies have validated the use of irreversible hydrocolloid material for routine impression-making, the undercuts created by the fixed appliances trap the impression material, resulting in deformation1 or dislodgement of the impression from the tray and sometimes even debonding of the brackets.2 Materials including beading wax, masking tape,3 and silicone putty4 have been proposed for covering the brackets and archwires to increase the accuracy of impressions.

Characterization of a parabolic solar cooker made from recycled materials

Currently, in some communities, firewood is still used to cook or conserve heat; this action generates great problems for health and the environment, one of them is the great risk of fires and/or asphyxiation due to smoke inhalation, another is the deforestation that is carried out to obtain firewood and, finally, the generation of methane, ozone precursors and carbon dioxide when burning any of these. This work proposes the use of a parabolic solar stove, made from recycled materials, such as cardboard, self-adhesive contact paper as reflective material, Masking tape®, which allows reducing manufacturing costs, helping low-income families and being environmentally friendly. The results obtained with respect to the time required for cooking various foods, the temperatures reached throughout the process, as well as information on meteorological variables obtained from the IQUERETA29 meteorological station located at the Technological University of San Juan del Río and administered by the Querétaro State Water Commission are shown.

Button battery taping prevents oesophageal injury.

Most button battery (BB) ingestions in children are unwitnessed leading to prolonged exposures and severe complications. One third of ingestions occur from free BB, that are stored or awaiting disposal. Recommendations have been made to cover the terminals of discarded BB with adhesive tape; however, it is unclear if this practice prevents injury. Our aim was to determine if tape could prevent oesophageal injury in a cadaveric porcine model. Electrical, masking, packing and duct tape were compared. One BB was left untaped. Taped BBs were placed in a cadaveric porcine oesophagus controlled for temperature and humidification. Specimens were assessed at 0, 0.5, and hourly for 6h by visual inspection, temperature and pH. BB voltage was measured before and after testing. All tests were repeated in triplicate. Oesophageal specimens demonstrated burn prevention in the packing and duct tape trials. Burns were seen in 2/3 trials with electrical tape and 3/3 trials with masking tape. pH remained neutral throughout the study for all packing and duct tape specimens. pH remained neutral initially for masking tape but increased rapidly to 12 by 2h. There was no change in battery voltage for the packing tape and duct tape trials. There was a 16.3% reduction in voltage for masking tape which was similar to controls. Taping BB with packing tape and duct tape prevented oesophageal burns. This may provide a novel method of burn prevention for loose BB intended for disposal.

Further Hospital Art Development of Masking Tape Using Thin Film Sheet

The authors and collaborators have continued practice of hospital art in the university and community hospitals and various research with experts. The material for hospital art is masking tape which is easily made and attached for everyone. Formerly, we have conducted artwork in front of the wall, which took a long time. Currently, we have tried to take the most advantage of the thin-film sheet. Our staff can prepare artwork with a size of 20 cm square in advance. Many square parts with double-sided attachment tape can be gathered together, which is completed and useful in a short time.

Climbing ability of Trogoderma granarium larvae on artificial household and insecticide-treated materials

The khapra beetle, Trogoderma granarium is a serious pest of stored grains in many nations. Larvae of T. granarium may be persistent in warehouse conditions due to the ability to enter facultative diapause. Thus, a better understanding of their behavior with respect to movement as they seek places of refuge or food may lead to improvements in the development of monitoring tools and control technologies. The distance that khapra beetle larvae walk on a variety of surfaces at different angles was examined for 10-min intervals. Certain surfaces such as plywood, sheetrock, tile, cement, and netting were much more easily climbed than plastic, painted cement, and metal. Movement would often increase when the surface inclination increased from 0° to 30°, but then decrease at 60° or 90°. Tape corridors promoted climbing, and those with paper-like surfaces such as masking tape or lab labeling tape provided the most benefit. Other tapes with slippery or textured surfaces did not promote climbing. We also tested the ability to move on plastic bag and netting material impregnated with insecticide at different angles. Regardless of insecticide treatment, plastic bags were much less amenable to larval movement than netting. At the same time, there was little effect of the insecticide on slowing movement in these brief trials. The results suggest that optimal placement of wall traps should include an assessment of the surface, and that incorporating insecticide-treated nets or bags into new technologies must account for larval mobility on such surfaces.

Button battery taping and disposal: Risk reduction strategies for the household setting

ObjectivesPediatric esophageal button battery (BB) injury occurs rapidly and continues to be a significant source of morbidity and mortality. Unfortunately, a BB that no longer supplies power to a device can still have enough residual voltage to cause injury within the body. Development of additional prevention strategies for consumers may reduce esophageal injury risk. MethodsIn this study, 24 commercially available button batteries (BBs) were horizontally and vertically wrapped (2 layers, full circumferential coverage, 90° apart) with 6 different types of common household tapes (Scotch®/clear, Scotch®/Magic, masking tape, packing tape/clear, packing tape/brown, black electrical tape) and left at room temperature for 30 days. In addition, 6 of the CR2032 batteries covered with each type of tape were placed in a cadaveric piglet esophageal model for a 4-h period and then compared to controls without tape for tissue pH changes and visible tissue injury. ResultsNone of the tape-wrapped batteries showed voltage changes nor presented any hazard stemming from BB ingestion. All 6 tape covered batteries placed in the cadaveric piglet esophageal tissue model demonstrated no visible tissue injury and no change in tissue pH in contrast to the controls. Review of BB packaging language from various brands of commercially available CR2032 batteries showed that none had specific disposal recommendations. ConclusionBoth BB and electronics manufacturers should consider instructing the use of common household tape options to cover these BB immediately after removal from a device for either recycling or disposal. Such precautions may help to reduce related ingestion injuries in children.

First report of Neopestalotiopsis protearum causing seed rot on Camellia oleifera in China.

Camellia oleifera, an evergreen small tree or shrub with high medicinal and ecological values, is mainly distributed in subtropical regions of China. Camellia oil obtained from Camellia oleifera seeds is rich in unsaturated fatty acids and unique flavors, and has become a rising high-quality edible vegetable oil in south of China (Zhuang 2008). The tea-oil tree Camellia oleifera plays important economic and ecological roles in Hunan province. During collecting trips, seeds of C. oleifera with disease symptoms have been observed in almost all oil-tea forests. In lab, the seeds can be infected by wounds and directly, however, wound infection is more rapid. In oil-tea forests, the wound of seed is often caused by external factors such as mechanical and insects. Symptomatic seeds exhibited brown rot symptoms with irregular, black spots, brown necrosis of the kernels, and accounted for 65% of the surveyed seeds (Fig. 1). Rotted seeds were surface-sterilized for 1 min in 75% ethanol, 3 min in 1% sodium hypochlorite, then rinsed for 2 min in sterile water and blotted on dry sterile filter paper. Discolored seed tissues were cut into pieces of 3 mm × 3 mm using a sterile scalpel, placed on potato dextrose agar (PDA) medium, and then incubated for 7 days at 25°C with a 12-h photoperiod. After 7 days of incubation, circular fungal colonies with dense aerial mycelium, produced black, wet spore masses. Four-septate conidia were ellipsoidal to obovoid, measuring 24 (22 to 26) × 6.5 (6 to 7) µm (n = 30). Conidia had three median cells, which were dark brown, with a single basal hyaline appendage, 4 (3.5 to 4.5) µm long, and two to four (usually three) apical hyaline appendages, 32 (27 to 35) µm long, similar to these recorded by Crous et al. (2011). Two single-spore isolates cultured on PDA medium were selected for DNA extraction. The ITS region was amplified using primers ITS5 and ITS4 (White et al. 1990). The partial translation elongation factor 1-alpha (tef1-α) gene region was amplified using primers EF1-728F (O'Donnell et al. 1998) and EF-2 (Carbone & Kohn 1999). The partial β-tubulin (tub2) was amplified using primers T1 and Bt2b (Glass & Donaldson 1995). The sequences of ITS (MW391815), tef1-α (MW398222), and tub2 (MW398223) were submitted to GenBank. BLAST analysis demonstrated that these sequences were 99%~100% similar to the sequences of ITS (MH553959), tef1-α (MH554377), and tub2 (MH554618) published for Neopestalotiopsis protearum. Phylogenetic analysis revealed that all the representative isolates recovered from symptomatic Camellia oleifera seeds showed 91% bootstrap support with Neopestalotiopsis protearum isolate in references (Fig. 2). Pathogenicity tests were conducted on 20 healthy seeds. We wounded the seeds by a sterilized needle on the middle position, and put the 5-mm-diameter agar plugs with actively grown mycelia (strain HNWC04) or pure PDA on the wound. We then covered the wounds with clean masking tape to prevent contamination and desiccation. After inoculation, the seeds were kept at 90 to 100% relative humidity at 25°C in a greenhouse for 3 weeks and monitored daily for lesion development. Twenty days after inoculation, all the seeds inoculated presented similar typical symptoms observed under natural conditions, whereas the control seeds showed no symptoms. Koch's postulates were fulfilled by reisolating the same fungus and verifying its colony and morphological characters as Neopestalotiopsis protearum. To our knowledge, this is the first report of Neopestalotiopsis protearum causing oil-tea seed rot in China.

Recent topics of complementary &amp; alternative medicine (CAM) include music/art therapy and hospital art

Recently, Complementary and Alternative Medicine (CAM) and Integrative Medicine (IM) have been broadly developed. IM involves both of CAM and Western Medicine (WM). Integrative Medicine Japan (IMJ) has developed CAM/IM in Japan, and author has managed Shikoku Island division of IMJ. Current topics include the music/art therapy for cancer patients, and hospital art (art in hospital) using convenient masking tape for satisfaction and improved health outcomes. The word “health” is from the Sanskrit language “Swasth”, which is combined of SWA (my) + STH (exist, keep) with meaning of self-existence under self-consciousness. Thus, CAM/IM can contribute the promotion of health.

Effects of Chronic Secondhand Smoke (SHS) Exposure on Cognitive Performance and Metabolic Pathways in the Hippocampus of Wild-Type and Human Tau Mice.

Background:Exposure to secondhand smoke (SHS) is a risk factor for developing sporadic forms of sporadic dementia. A human tau (htau) mouse model is available that exhibits age-dependent tau dysregulation, neurofibrillary tangles, neuronal loss, neuroinflammation, and oxidative stress starting at an early age (3–4 months) and in which tau dysregulation and neuronal loss correlate with synaptic dysfunction and cognitive decline.Objective:The goal of this study was to assess the effects of chronic SHS exposure (10 months’ exposure to ) on behavioral and cognitive function, metabolism, and neuropathology in mice.Methods:Wild-type (WT) and htau female and male mice were exposed to SHS (90% side stream, 10% main stream) using the SCIREQ® inExpose™ system or air control for 168 min per day, for 312 d, 7 d per week. The exposures continued during the days of behavioral and cognitive testing. In addition to behavioral and cognitive performance and neuropathology, the lungs of mice were examined for pathology and alterations in gene expression.Results:Mice exposed to chronic SHS exposure showed the following genotype-dependent responses: a) lower body weights in WT, but not htau, mice; b) less spontaneous alternation in WT, but not htau, mice in the Y maze; c) faster swim speeds of WT, but not htau, mice in the water maze; d) lower activity levels of WT and htau mice in the open field; e) lower expression of brain PHF1, TTCM1, , and HSP90 protein levels in WT male, but not female, mice; and f) more profound effects on hippocampal metabolic pathways in WT male than female mice and more profound effects in WT than htau mice.Discussion:The brain of WT mice, in particular WT male mice, might be especially susceptible to the effects of chronic SHS exposure. In WT males, independent pathways involving ascorbate, flavin adenine dinucleotide, or palmitoleic acid might contribute to the hippocampal injury following chronic SHS exposure. https://doi.org/10.1289/EHP8428

Laser assisted sampling vs direct desorption flowing atmospheric pressure afterglow mass spectrometry of complex polymer samples: Forensic implications for pressure sensitive tape chemical analysis

Flowing atmospheric pressure afterglow (FAPA) mass spectrometry (MS) is an easy-to-use, cost-effective, and potentially portable technique that allows direct desorption/ionization from samples with little-to-no sample preparation for real-time chemical analysis. However, it has limitations regarding analytes with low desorption efficiency, such as polymers. Here, laser assisted sampling (LAS) is developed and coupled to FAPA MS to allow access to a wider range of chemical information from polymer samples. This is achieved through laser-induced pyrolysis conditions that provide a much higher degree of spatio-temporal control compared to typical pyrolysis techniques. LAS FAPA MS, together with direct desorption FAPA MS, is implemented on pressure sensitive adhesive (PSA) tape samples, which are often found at crime scenes and recovered as forensic evidence. Comparative PSA tape examination is typically performed to assess any differences in the comparison of unknown and known samples and provide an evidentiary association between suspects and crime scenes in forensic applications. PSA tape samples from several manufacturers of duct, masking, and electrical tape were analyzed from the adhesive and backing side. Direct desorption FAPA provides top-surface selectivity and the tape mass spectra are dominated by more peaks at lower m/z, many of which correspond to polymer additives. LAS gives access to sampling from all of the tape layers and the FAPA mass spectra is extended to higher m/z, while polymer fragmentation patterns are evident. Principal components analysis (PCA) was implemented to assess the ability of each technique to distinguish and categorize identified tape classes within the sampled population. The complementary nature of the resulting mass spectra from direct desorption vs LAS FAPA was evident from the PCA as different tape brands sub-sets were discriminated by each technique. The differentiation obtained by combining both methods is already competitive, or better, than conventional techniques, with the additional benefits of AMS.

Masking Tape Art-Work May Provide Beneficial Positive Effects

Background: The authors and colleagues have been involved in treatment and care for the elderly with rehabilitation, Integrative Medicine (IM), art in hospitals for artworks using masking tape. Combined together, we conducted a pilot study for medical application of masking tape art-work for elderly subjects. Subjects and Methods: Subjects enrolled were 12 elderly patients with dementia regularly coming to day care center for rehabilitation (M/F 3/9, 78-100 years, 88.3±6.0 years). As methods, masking tape has been known as Washi Tape (wa=Japanese and shi=paper), which is adhesive tape easily to stick and peel off for decorative work. Protocol included i) working 2-3 times a week, ii) sticking masking tape on a rough sketch paper, iii) evaluation of several biomarkers before and after the intervention. Results: i) Artworks were performed satisfactory for each case, ii) grasping power (right) showed increasing tendency from 13.5±7.7kg to 14.8±6.8kg (p=0.11), iii) vitality test showed significantly increase (p=0.02). Discussion and Conclusion: Artworks of masking tape seem to be beneficial for improving grasping power and psychological condition. This study included other biomarkers such as Mini-Mental State Examination (MMSE), pinch power, language word test and Barthel index. We plan to develop further detail analyses in the future research.
