Portrayal of Love and Social Issues of LGBTQIA+ in Pinoy Boys’ Love (BL) Series

Drama as a performing art has changed dramatically over the years in terms of production quality, story, and platform it is performed. Recently, it has diversified from tackling societal issues such as same-sex relationships. The study analyzed how to love and social issues are portrayed in selected Pinoy Boys' Love (BL) series by conducting a content analysis. The findings revealed Pinoy BL series had proven its capacity to depict love in nonromantic situations inclusively and concluded that expressing love entails more than an emotion. It also comprises expressing it through language, in which words can make individuals feel loved because of the encouragement and affirmation they get. It has also been seen that love also comprises movements in which people who cannot openly express their love for another person through words may still do so by doing kind and pleasant gestures and deeds for them. Love may also develop through time; it has been demonstrated in the BL series that spending time together can help individuals reconnect with their lovers, friends, and families and rekindle desire in people who have lost the spark in their relationship. The potential of the BL series to show the hardships that LGBT people had historically and continue to face in society was also noted, including personal-social and political-social concerns that affect them, proving that the BL series is intended to depict LGBTQIA+ themes seriously and realistically.

Post-market quality assessment of 22 ciprofloxacin brands by HPLC available in Bangladesh market

Antibiotic resistance has been recognized as a public health threat in recent years, and mortality due to resistance is increasing alarmingly every year. Antibiotic resistance, among many factors, may arise due to the consumption of substandard antibiotic brands that provide subnormal levels of the drug in the blood. Post-market evaluation can provide important information in assessing pharmaceutical products in terms of quality, purity, and therapeutic aspects. Ciprofloxacin, a broad-spectrum antibiotic, has been used against a wide range of infectious diseases in Bangladesh. The present study aimed to determine the quality attributes of twenty-two commonly prescribed brands of ciprofloxacin 500 mg tablet collected from Dhaka city and the rural regions of Jessore. RP-HPLC coupled with UV–visible spectrophotometry was used to determine the potency of ciprofloxacin in tablets, and the zone of inhibition was determined using Kirby-Bauer's disc diffusion method to assess the antimicrobial efficacy against different strains of microorganisms. We found that 95.45% of brands (21 out of 22 brands) of ciprofloxacin tablets met United States Pharmacopoeia (USP) and British Pharmacopoeia (BP) specified potency, whereas one brand failed. From dissolution studies, we observed that 68.2% of brands (15 out of 22 brands) followed USP/NF dissolution test specifications, whereas 31.8% (7 out of 22 brands) failed to release 80% of the labeled amount of drug within 30 min. Drug release kinetics data showed that most brands followed the Weibull drug release kinetic model. Fit factor analysis exhibited that 8 brands out of 22 (36.4%) failed to comply similar dissolution profiles with the reference product. Minimum inhibitory concentrations, assessed against five bacterial strains, further showed good antimicrobial sensitivity by all brands.

Investigating the compressibility and flowability of cocoa powders: A solution for chocolate industry

AbstractThe flowability and compressibility properties were determined for two types of cocoa powders, which are used commercially in chocolate industries; alkalized and natural cocoa powders. Physical and flow properties have a very significant role in the flow behavior, which relates to the handling, transportation, and storage of bulk powders. Throughout the research, it was observed that the properties of both cocoa powders are similar. The objectives of this work are to compare the compressibility and flowability between alkalized and natural cocoa powders and to design the minimum opening size of hopper for mass flow based on their flow properties. Jenike's mathematical methodology is applied during the research for the design of conical hoppers for mass flow. Besides, powder flow analysis using powder flow analyzer is one of the testing methodologies in this research. In addition, direct shear box tests were performed with three different normal stresses. The alkalized cocoa powder needs 1.366 m in diameter for the opening of the hopper, while the natural cocoa powder needs 1.531 m. From the results of the study conducted, it was concluded that both cocoa powders are very cohesive and have poor flow properties. This research reveals that the physical and flow properties of two main types of cocoa powder contributed a lot to the process of hopper design, enhance process understanding, and also applicable for analyzing the powder behavior at any stage in industry.Practical applicationsCocoa powder is the essential ingredient of chocolate manufacturing and other food industry having a chocolate‐like flavor including beverages, biscuits, desserts, and so forth. In chocolate industry, the flow behavior of cocoa powders can affect manufacturing efficiency, which directly affects the production capacity and product quality in terms of its weight and content uniformity. In this study, the critical design parameters such as hopper angle and size of opening were determined to improve the flowability of cocoa powders when passes through hopper. The findings of the present study make it possible for an accurate estimation of a correct intersection with the hopper flow factor line and effective angle of internal friction (δ), extrapolating the powder flow function ff curve to obtain hopper opening size for each cocoa powder for better flowability.

Potential Usage of Selected Agro-Residue as a Biofuel Production Sources: Physiochemical Evaluation Approach

This article present physiochemical characterization of commonly available agricultural waste residues on dry basis for: (Corn cob, Coconut shell, Cashew nut, Palm kernel shell and Cassava stem) with the view to evaluate their respective suitability for biofuel production using thermochemical conversion process. The investigated respective biomass feedstock milled samples was analyzed in the laboratory for fuel physiochemical characterization. The physiochemical characterization carried out on each biomass waste sample are Proximate Analysis, Ultimate Analysis, Elemental composition analysis and determination of their respective Higher heating Value(HHV). The obtained results revealed that of all the biomass samples characterized, the Coconut shell (CNS), Corn cob(CC) and Cassava stem(CS) samples proved to possess the most suitable characteristics for better bio-oil production. Palm kernel shell(PKS), Coconut shell(CNS) and Cashew nut(CN) due to their obtained low ash content, adequate hardness and fairly high fixed carbon content are generally regarded to be a potential source for making quality grade charcoal (bio-char) using Pyrolysis process. Gasification process is found desirable to producing high yield of bio-gas for Corncob(CC) and Cassava stem(CS) biomass samples due to their respectively obtainable high value of moisture content: (13.4%wt and 15.10%wt.) and fixed carbon contents of (67.94%wt and 74.13%wt) in this study. Moreover, among all other biomass sample investigated in this study, Coconut Shell(CNS) in comparison to all other samples characterized attained highest HHV of 31.2 MJ/kg. Negligible amount of Sulphur and Nitrogen which could resulted to lower emission of SO2 and NO2 if use directly for heating purposes aftermath application of any of the thermochemical conversion processes is also observed for the biomass waste samples analyzed independent of their types. These results show that the characterized biomass samples could be a suitable candidate for alternative energy fuels production in terms of quality and environment concern.

The Influence of Consumer Perceptions on Product Attributes towards Brand Preferences of Alpina Outdoor Sport and Eiger Adventure

Alpina and Eiger are outdoor product pioneers in Indonesia. Initially, Alpina dominated the Indonesian outdoor product market, but it was unable to compete with Eiger. According to the preliminary research findings, more than 50% of respondents claimed that they prefer to buy outdoor products from Eiger over Alpina because Eiger products are superior in terms of product quality, product features, and product style & design. In this study, the independent variables are product attribute variables (product quality, product characteristics, and product style & design), and the dependent variable is brand preference. Data was gathered through interviews, observations, literature studies, and questionnaires completed by 120 people using the judgement sampling approach. Multiple linear regression study results reveal that product attribute dimensions have a positive and significant influence on brand preference simultaneously. According to the coefficient of determination calculation results, the independent variable contributes 45.1% to the dependent variable.

Pricing strategies in reward-based crowdfunding: Whether to introduce price guarantee?

Reward-based crowdfunding often exhibits high uncertainty in terms of product quality and market performance; thus, consumers may choose to strategically delay their purchases until crowdfunding succeeds. Price guarantee (PG) is adopted by some crowdfunding platforms to encourage consumers’ participation in crowdfunding, but it also reduces the flexibility to change prices in the future. To address the strategic issue for reward-based crowdfunding regarding whether to introduce PG, we develop a two-stage theoretical model composed of a crowdfunding stage and a regular selling stage. The results show that whether to introduce PG heavily depends on the crowdfunding project’s funding target and community benefit. When the funding target is relatively low, the creator can offer PG as an effective substitute for community benefit to achieve crowdfunding success and increase profit, but it is unwise to offer both. That is, introducing PG can simultaneously increase the crowdfunding amount and the two-stage profit in the case of relatively low community benefit. When the funding target is relatively high, the creator will adopt a target-dependent pricing scheme to guarantee crowdfunding success. In this case, PG can increase the upper bound of the funding target but will decrease the profit in most situations. Our results also show that PG can increase both the creator’s and consumers’ payoffs under some conditions. The main findings are verified by means of empirical examples, and some managerial insights are obtained.

Assessment of the impact of the industrial enterprise on the environment by determining the integrated (generalized) energy efficiency performance indicator

The article summarizes the efficiency indicators. The authors have developed comprehensive efficiency indicators of the enterprise for a complete assessment of the efficiency of energy use. The comprehensive efficiency index of the enterprise is divided into three stages: generation of energy, energy transmission and energy consumption. In this case, the efficiency of using primary energy resources in the enterprise was accepted as a priority criterion. The integrated (generalized) energy efficiency indicator of the industrial enterprise was developed taking into account the participation of renewable energy sources in the energy consumption of the enterprise and the impact of energy consumption on the environment. The most effective way to green production and reduce carbon emissions per unit of product is through energy efficiency testing. Capturing and reducing carbon emissions per product can be achieved through energy efficiency research. It has good energy efficiency in terms of production quality and ease of production methods. The article describes in detail not only the evaluation methodology for evaluating the impact of production on the environment, but also the energy intensive in the production of unit of product and the coefficient of efficiency work in energy production and transmission in generalized indicators.

Holistic Approach for Digitalized Quality Assurance in Battery Cell Production

In this paper, we introduce a holistic approach to consider quality assurance (QA) for battery cell production (BCP). The framework, the explanation of the individual components as well as their interfaces and dependencies, and a detailed description are presented. Firstly, the level of necessary data (e. g. provided by online and out-of-line measurement systems) for the inspection of quality is presented. The aggregation of the recorded data as well as their tracing are ensured by the realization of a traceability system. Subsequently, by defining a suitable intelligent quality gate system, QA mechanisms are implemented and an active influence on production 3 e. g. by adaptive process control or identifying and reducing negative influence of cause-effect relationships 3 is aimed at. Finally, optimization of BCP in terms of product quality and its sustainability will be enabled. The evaluation of the demonstrated approach in practice is outlined based on an exemplary process of BCP.

Comparative evaluation of physical characteristics and volatile flavor components of Bangia fusco-purpurea subjected to hot air drying and vacuum freeze-drying

Bangia fusco-purpurea is an economically important seaweed with Fujian characteristics. Given that its harvest is seasonal, drying is often used to remove moisture, extend storage time, and facilitate further processing. Hence, the current study sought to explore the impact of different drying processes on the quality and volatile fingerprints of Bangia fusco-purpurea. To this end, the effects of hot air drying (HAD) and vacuum freeze drying (VFD) on the drying characteristics, microstructure, rehydration, and volatile components of dried B. fusco-purpurea were investigated. The results showed that the water removal efficiency of HAD was significantly higher than that of VFD. However, VFD better preserved the skeletal structure of B. fusco-purpurea than HAD, with a faster rehydration rate and a more uniform cell structure after rehydration. Using electronic nose and comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (GC × GC-TOF MS), significant differences in the volatile profiles of fresh, HAD, and VFD B. fusco-purpurea were assessed. E-nose analysis revealed that both HAD and VFD treatments significantly reduced sulfides, aromatic compounds, and nitrogen oxides in fresh B. fusco-purpurea. However, the alcohol, aldehyde, and ketone contents were lower in the VFD samples compared with HAD and fresh samples, whereas the content of methyl flavor substances was significantly higher. GC × GC-TOF MS analysis revealed that the most abundant volatile categories in HAD and VFD were hydrocarbons, alcohols, and esters. The number of volatile components in the HAD samples was significantly lower than in the VFD and fresh samples. As drying progressed, hydrocarbons and alcohols were formed in dried B. fusco-purpurea due to the thermal degradation of carbohydrates, lipids, amino acids, and the Maillard reaction. There were also significant flavor differences between HAD and VFD B. fusco-purpurea. Thus, although HAD exhibits better drying efficiency, VFD has more significant advantages in terms of product quality.

Yield and product quality of processed sandfish (Holothuria scabra) using different processing techniques

Four different techniques in processing sandfish: a) MB-method described by Brown et al. (2010), b) MN- from NFRDI, per Pardua et al. (2018), and two variations of method from Purcell (2014), c) MP1, and d) MP2 which were slightly modified and tried to compare resulting product quality and yield from freshly gutted sandfish. This demonstration was to encourage sandfish ranch managers to add value to their sandfish and ensure better earnings. Twenty-four sandfish individuals (350 to 870 g) harvested from the sea ranch site at Maliwaliw Island were used for processing at six individuals per technique. Results show that live sandfish weight was reduced to 45% after gutting. MB had the highest weight percent recovery from gutted weight at 10.75%, not significantly different (p > 0.05) from MN at 9.65% but significantly higher (p < 0.05) from MP1 (9.38%) and MP2 (9.50%). In terms of product quality, bigger sandfish >600 g produced good quality products when processed correctly. Bêche-de-mer is priced based on three criteria: quality of the product, size length, and weight. Although there is no single best-practice method for processing sandfish, sea ranch managers may opt to adopt the MB and MN for a simpler procedure to save time and resources, and higher product yield for better income.

A Feedforward Model Predictive Controller for Optimal Hydrocracker Operation

Hydrocracking is an energy-intensive process, and its control system aims at stable product specifications. When the main product is diesel, the quality measure is usually 95% of the true boiling point. Constant diesel quality is hard to achieve when the feed characteristics vary and feedback control has a long response time. This work suggests a feedforward model predictive control structure for an industrial hydrocracker. A state-space model, an autoregressive exogenous model, a support vector machine regression model, and a deep neural network model are tested in this structure. The resulting reactor temperature decisions and final diesel product quality values are compared against each other and against the actual measurements. The results show the importance of the feed character measurements. Significant improvements are shown in terms of product quality as well as energy savings through decreasing the heat duty of the preheating furnace.

Çok katmanlı algılayıcı ağı, uzun kısa süreli bellek ağı ve regresyon yöntemleri ile tarımsal kurutma tahmini

One of the processes used in the production of fertilizers, which has become an important part of agriculture, is the drying process. Determination of proper drying parameters is important both in terms of product quality and production efficiency. Regression methods are used to determine the drying process parameters frequently. In this study, in addition to the regression method, machine learning techniques are also examined such as artificial neural network, long short term memory method. The data obtained from the drying process of a commercial organomineral fertilizer consisting of a mixture of 5% nitrogen and 10% phosphorus at 70˚C, 75˚C, and 80˚C were used for modelling. The simulation results obtained from the models of the methods and the data obtained from the experiments were compared. The predictions and performances of each model were presented. Determination the appropriate drying parameters is It is important for the drying efficiency of the product. In addition, model selection plays an important role in obtaining successful results in drying simulations. As a result, it has been observed that the prediction performance of the model created with the artificial neural network is more successful than the others. While regressions are efficient in modelling existing data, they are not successful in predicting. Moreover, it is not enough to predict the peak and pits in the drying data.
