Authors: Zeng Nani
Published: November 2022

This study aims to improve the effectiveness of online music teaching and optimize the current interactive system of online teaching. Firstly, the basic connotation of Convolutional Neural Network (CNN), edge-cloud computing and their application principles are discussed. Then, the basic principles of wireless communication and its comprehensive optimization methods are discussed. Finally, the Softmax Convolutional Neural Network-Long Term Evolution (SCNN-LTE) model based on CNN to optimize wireless communication technology is designed. Model skills are comprehensively assessed. The results show that, compared with other models, the comprehensive performance of the designed CNN model has been greatly improved. The evaluation found that the recall value of the Softmax Convolutional Neural Network (SCNN) model is around 0.9-1.0, and the precision value is around 0.8–0.9. Additionally, CNN models are applied to wireless communication technologies for performance evaluation. The accuracy of the SCNN-LTE model is generally between 0.7 and 0.9. The designed model not only optimizes the CNN model to a certain extent but also deeply optimizes the wireless communication technology. Therefore, the model can be better applied to the online music teaching interactive system, providing important technical support for its effect optimization. This study not only provides a technical reference for the optimization of wireless communication technology but also contributes to the performance enhancement of the online music teaching interactive system.
Curriculum Design of Sports Humanities and Sociology Based on Intelligent Edge Cloud Computing and Artificial Intelligence
Authors: Zhang Liangyu , Zhao Jinkun
Published: November 2022

The course of sports humanities and sociology occupies an important position in the contemporary education system. However, in the classroom teaching process, the current teaching of sports humanities and sociology is far from the expected effect, which is not conducive to the play of the value and role of the curriculum. In this context, it is very necessary to innovate and explore the teaching mode of sports humanities and sociology courses. Under the artificial intelligence wireless network environment, the professional courses of sports humanities and sociology have been researched and set up, and a reconstruction decision algorithm is proposed. In the course setting, the intelligent edge cloud computing theory designed the information management system for massive course data. When the system is deployed, edge nodes are introduced into each data collection area. The system consists of data collection, transmission, and query and analysis modules. Firstly, the network parameters that need to be changed are obtained by analyzing the factors that affect the performance, and the data are reconstructed and deployed. These changes are mapped into the actual network structure. This not only ensures that the system can adapt to the dynamically changing environment but also saves time of system operation. Two results are obtained: on the one hand, the artificial neural network is good at processing complex multi-domain information; on the other hand, artificial intelligence introduces a learning mechanism into reconstruction decision-making, which ensures the correctness and optimization of reconstruction decisions. The course data management system based on intelligent edge computing can meet the storage and query requirements of millions of data items. Based on this algorithm, the sports humanities and sociology courses are set up to maintain a balanced state that ensures the course runs well. Ultimately, sports humanities and sociology courses can better serve teachers and students and then serve social progress.

Published: November 2022

Purpose

Many cancer survivors experience chronic pain after completing curative-intent treatment. Based on available data, chronic pain may be undertreated in this context; however, little is known about cancer survivors’ experiences with clinical management of chronic pain. The purpose of this study was to better understand cancer survivors’ pain management experiences after curative-intent treatment.

Methods

We conducted 13 semi-structured interviews with a convenience sample of cancer survivors who had completed treatment for stage I-III breast, head/neck, lung or colorectal cancer. We used a thematic approach to qualitative data analysis.

Results

Participants described that chronic pain often goes unrecognized by their providers, potentially due to limitations in how pain is assessed clinically and the tendency of both cancer survivors and some providers to minimize or invalidate the pain experience. To improve communication, participants suggested that providers ask more open-ended questions about their pain, help them to establish functional goals, and provide patients with options for pain management.

Conclusions

This study demonstrates the importance of provider-initiated communication around pain management for cancer survivors to make them feel more supported in their care.

Implications for Cancer Survivors

Communication and shared decision-making interventions may improve cancer survivor-provider communication around chronic pain management, addressing an important gap in survivorship care.
Urban/Rural Spatial Price Discrimination with Online Competition
Authors: Guo Wen-Chung , Lai Fu-Chuan
Published: November 2022

We contribute to the previous offline spatial price discrimination by adding an online entrant that results in partially equalized prices, and the urban (rural) segments are served by the offline (online) firms. Online competition induces the offline firms to move closer to the market center, which causes the equilibrium locations to no longer be the social optimum due to the online price distortion. The greater the online advantage is, the higher the online price, the less dispersed the offline locations, and the lower the offline prices will be in urban areas. Finally, zoning policies and two extensions of online price discrimination and multiple offline firms with free entry are offered.

Published: November 2022

As an abundant bioresource of carbon, lignin has the potential to form carbon fibers (CFs), which can then be used as electrode materials in supercapacitors. However, most studies have only focused on the morphology of CFs, such as the specific surface area and pore-size distribution, while ignoring the influence of the carbon structure in CFs. In this study, Ni(acac)2 was used as a graphitization catalyst in CFs preparation and to further modify the morphology of the fibers. Meanwhile, the addition of Ni(acac)2 remarkably shortened the thermostabilization period from 76 h to 2.25 h, which significantly reduced the energy consumption. The resulting lignin-based activated carbon fibers (LACFs) with graphitized structures presented a controllable pore-size distribution and large surface areas up to 582.7 m2 g− 1. These LACFs were then used as electrode materials in supercapacitors, and the assembled devices displayed high energy and power densities of up to 22.1 Wh kg− 1 and 239 kW kg− 1, respectively, using organic electrolytes.

Background: Many factors determine the success of wearing contact lens, including knowledge and compliance towards lens care. This study aimed to evaluate the level of knowledge and compliance between two groups of adult contact lens wearers in Kuala Lumpur, Malaysia. Methods: A total of 60 participants aged 18–30 years old volunteered to participate in this study (30 participants prescribed contact lenses at the Universiti Kebangsaan Malaysia [UKM] optometry clinic and 30 participants fitted at private practices). Participants were interviewed using a structured questionnaire consisting of nine questions on basic knowledge related to lens wear and 13 questions on compliance, categorised into questions on the cleaning process, disinfection, accessories care and replacement schedule. Results: All participants wore disposable contact lens 53.3% (n = 32) participants preferred using monthly disposable lenses. Both groups had the same level of knowledge, except knowledge of the effects of makeup (P < 0.000) and duration of the solution used for cleaning (P < 0.010), showing lack of knowledge on contact lenses among participants in private practices group. There were no significant differences between the groups in terms of the level of compliance with the cleaning process (P = 0.830), disinfection (P = 0.725), accessories care (P = 0.865) and replacement schedule (P = 0.699). Conclusion: Participants from UKM optometry clinic had better knowledge on wearing contact lens; moreover, both groups had good compliance towards lens care. Contact lens practitioners should provide all the necessary information to contact lens wearers so that they are equipped to handle contact lenses correctly, which would minimise the risk of eye complications.

Published: November 2022

Tetrahedrite-(Ni) (IMA2021-031), ideally Cu6(Cu4Ni2)Sb4S13, is the first natural Ni-member of tetrahedrite group mineral found in Luobusa chromite deposit, Tibet, China. The new species occurs as anhedral grains 2 to 20 μm in size, associated with gersdorffite, vaesite, and chalcostibite, which are disseminated in a matrix of dolomite, magnesite, quartz, Cr-rich mica, and Cr-bearing clinochlore. Tetrahedrite-(Ni) is black in color with a reddish-black streak and metallic luster. It is brittle with uneven fractures and has a calculated density of 5.073 g·cm–3. The mean values of 9 electron microprobe analyses (wt%) are Cu 39.83, Ni 5.67, Fe 1.45, Sb 21.69, As 5.45, S 25.39, total 99.48, and the empirical formula calculated on the basis of cation = 16 apfu is M(2)Cu6.00M(1)[Cu4.03(Ni1.55Fe0.42)Σ1.97]Σ6.00X(3)(Sb2.85As1.16)Σ4.01S12.67. Tetrahedrite-(Ni) is cubic, with space group I43m, a = 10.3478(4) Å, V = 1108.00(14) Å3, and Z = 2. Its crystal structure has been solved by X-ray single-crystal diffraction on the basis of 188 independent reflections, with a final R1 = 0.0327. Tetrahedrite-(Ni) is isostructural with tetrahedrite group minerals. It represents the first natural tetrahedrite-group mineral with a Ni-dominated charge-compensating constituent. Tetrahedrite-(Ni) may be the product of late-serpentinization at moderately high-temperature conditions around 350 °C. In this case, tetrahedrite-(Ni) and its mineral paragenesis record an entire geological process of nickel enrichment, migration, activation, precipitation, and alteration from deep mantle to shallow crust.

Published: November 2022

Chicken eggs are divided into several types including omega-3 chicken eggs, native chicken eggs, Arab chicken eggs, and domestic chicken eggs. Visually to distinguish the type of domestic and omega-3 chicken eggs have difficulty because physically the shape of the eggshell and the color of the chicken eggs look the same. Visual inspection of the two types of chicken eggs has a weakness because it only relies on the sense of sight that has limitations, and the results are less accurate because it is very dependent on the interpretation of each consumer. This research aims to distinguish the two types of domestic and omega-3 chicken eggs which pre-processing techniques of contrast stretching, brightness, histogram equalization, changing color images to gray images, then the k-mean image segmentation process is carried out. clustering, morphological operations, dilation, and erosion. Next, the first-order statistical feature extraction is done by calculating values namely mean, variance, entropy, skewness, and kurtosis results from the histogram. The final step is to look for eigenvalues, the eigen vector PCA method used to distinguish omega-3 egg types. The results in the form of plot graphs of mean and entropy features after the second rotation show that the first-order statistical feature extraction method and PCA method can be used to significantly distinguish the types of lehorn chicken and omega-3 chicken eggs.

Published: November 2022

An application for data collection of stunting cases has been developed with data visualization in digital maps. This detailed information about stunting is a solution offered to solve problems in areas prone to stunting. This system requires further testing to get feedback from several relevant stakeholders. The COBIT 5 framework, with a combination of DSS and MEA domains, is used in this study to test this geography-based system of stunting cases. The interviews with system administrator respondents showed that the lowest scores were in the DSS05 and MEA02 domains of 75.20 and 74.67 on the Linkert scale. The same results were also obtained from management respondents consisting of heads of Puskesmas and midwives, 77.54 and 75.95. In the end, the level of achievement of the domain of the current system and its monitoring is compared between the current condition (as-is) and the general condition (to-be), indicating a gap. Based on the gap analysis, two-gap values were obtained in the DSS05 and MEA02 domains. Recommendations for improvement in the future are in terms of vulnerability to errors and increasing the ability of internal parties to control the system to handle errors.

The challenge in controlling the supply of beverage ingredients is strongly influenced by the stable condition of supply, prices and differences in the shelf life of the beverage ingredients themselves. The high cost of beverage ingredients such as milk, flavoring powder and the difficulty of finding supplies of certain beverage ingredients, all of the increase in prices and difficulties will certainly affect operations. There are three choices, either increase the price, reduce the profit, or reduce the portion size. All these choices will not be easy to decide. This study aims to build an information system by applying the concept of continuous review (Q,r) on the economic order quantity (EOQ) model to optimize the supply of beverage ingredients. With the application of the concept of continuous review (Q, r) in the economic order quantity (EOQ) model on robusta coffee beans  produces  the order quantity is 521.15 grams each time an order is at the inventory level at 746 grams, palm sugar produces the order quantity is 1,430.71 grams every time you order at a stock level at 1124 grams, UHT milk produces the order quantity is 1,188.4 ml each time you order at a stock level at 7462 ml, and sweetened condensed milk produces an order amount of 802,6 grams each time you order at a stock level of 758 grams.
Towards explicit discrete holography: Aperiodic spin chains from hyperbolic tilings
Authors: Basteiro Pablo , Di Giulio Giuseppe , Erdmenger Johanna , Karl Jonathan , Meyer Rene , Xian Zhuo-Yu
Published: November 2022

We propose a new example of discrete holography that provides a new
step towards establishing the AdS/CFT duality for discrete spaces. A
class of boundary Hamiltonians is obtained in a natural way from regular
tilings of the hyperbolic Poincaré disk, via an inflation rule that
allows to construct the tiling using concentric layers of tiles. The
models in this class are aperiodic spin chains, whose sequences of
couplings are obtained from the bulk inflation rule. We explicitly
choose the aperiodic XXZ spin chain with spin 1/2 degrees of freedom as
an example. The properties of this model are studied by using strong
disorder renormalization group techniques, which provide a tensor
network construction for the ground state of this spin chain. This can
be regarded as discrete bulk reconstruction. Moreover we compute the
entanglement entropy in this setup in two different ways: a
discretization of the Ryu-Takayanagi formula and a generalization of the
standard computation for the boundary aperiodic Hamiltonian. For both
approaches, a logarithmic growth of the entanglement entropy in the
subsystem size is identified. The coefficients, i.e. the effective
central charges, depend on the bulk discretization parameters in both
cases, albeit in a different way.

Authors: Medeiros Juliana Barbosa , Paes Neir Antunes
Published: November 2022

Uma característica do envelhecimento populacional é o rápido crescimento da população de centenários em algumas regiões do mundo. Centenários, por definição, são sobreviventes que chegaram aos cem anos, ou seja, viveram cerca de 20 anos a mais do que a expectativa de vida média dos países desenvolvidos. Há o interesse sobre o estudo da população de centenários pelo histórico que permeia este grupo específico com relação à superestimação e baixa fidedignidade das informações nos censos demográficos. O objetivo deste estudo consistiu em realizar uma análise exploratória da qualidade da contagem censitária dos centenários no Semiárido Brasileiro em 2000 e 2010. Tratou-se de um estudo exploratório e descritivo, com abordagem quantitativa, constituído por dados secundários de indivíduos com cem anos ou mais, residentes no Semiárido Brasileiro. Para proceder à investigação comparativa e analisar a qualidade dos registros utilizou-se dados dos centenários no mundo, encontrados em 85 países que fazem parte da Organização das Nações Unidas (ONU). Os resultados encontrados neste trabalho evidenciam que a contagem censitária dos centenários no Semiárido Brasileiro evoluiu ao longo de 10 anos. Mesmo com o avanço observado, porém, os indicadores da região ainda estão distantes dos encontrados nos países mais desenvolvidos, fato este preocupante, que merece atenção e cuidados na captação desse contingente populacional no próximo censo demográfico.

Published: November 2022

The research aims to understand how external knowledge absorption happens, that is, how knowledge absorption capacity is developed in organizations that adopt a simple structure organizational configuration. The present study is characterized as an empirical of an applied nature, a qualitative approach and concerning the procedures, it is descriptive. The method used here was the case study. The data were collected through structured interviews with a script, and they were analyzed using the content analysis technique. The recognition capacity is favored by the employees' individual capacities and by their autonomy. The independence of the employee is driven by the charismatic leadership of the manager. The assimilation capacity, in turn, happens based on the individual skills and competences of the company members, also through training and informal team meetings. It is understood that the development of the assimilation capacity is minimized by the centrality in decision making by the main manager. This also occurs with the ability to apply knowledge, as a single individual has control over decision making, acting between strategic and operational issues. A multidimensional understanding of the constructive absorption capacity is proposed from the perspective of its relationship with the organizational configuration, since the organizational configuration can influence, in different ways, the efficiency and effectiveness of the recognition, assimilation and application process. knowledge. To present this relationship in a theoretical-empirical study is a relevant contribution to the study on this field.

Published: November 2022

A inovação foi responsável por saltos significativos de desenvolvimento ao longo do tempo, promovendo prosperidade econômica e bem-estar social. Esses avanços, entretanto, não foram suficientes para conter o crescente aumento da desigualdade no mundo e têm posto em questionamento o impacto das inovações modernas diante das passadas. Dada essas considerações, este artigo de abordagem ensaística tem como objetivo discutir a influência da trajetória do campo de inovação no desenvolvimento das sociedades e os rumos que podem ser tomados para uma inovação que promova desenvolvimento mais justo e igualitário. Para tanto, são discutidos os paradigmas tecnoeconômicos representados pelas cinco grandes ondas de inovação, o impacto esperado das inovações diante das demandas atuais, e as ações que podem ser desenvolvidas para inovações que tragam desenvolvimento socioeconômico mais igualitário. Espera-se que os insights gerados neste ensaio possam trazer um olhar crítico sobre o papel da inovação na redução da desigualdade no mundo e contribuam para o desenvolvimento de novas pesquisas acerca da temática, além de estimular a formação de discursos de desenvolvimento que tragam perspectivas mais justas e inclusivas e que denunciem os efeitos perversos da inovação.

Determinants of Glaucoma Therapy Escalation After Descemet-Stripping Automated Endothelial Keratoplasty To Treat Pseudophakic Bullous Keratopathy: A Nested Case-Control Study
Authors: AlDarrab Abdulrahman
Published: November 2022

Purpose:

To study the determinants of glaucoma therapy escalation (GTE) after Descemet-stripping automated endothelial keratoplasty (DSAEK) for pseudophakic bullous keratopathy in an eye-care hospital in Saudi Arabia.

Methods:

This nested case-control study evaluated patients who required medical or surgical treatment for controlling glaucoma after DSAEK (defined as GTE; GTE group). A group of patients who did not require any intervention post-DSAEK served as controls (control group). Data were collected on preoperative, intraoperative, and postoperative parameters for DSAEK. Variables were compared between groups to evaluate risk factors for GTE and graft failure.

Results:

The study sample comprised 117 eyes (40 in the GTE group and 77 in the control group). Glaucoma was present in 20 (17.1%) of the eyes before DSAEK. The median duration of follow-up was 27 months [Interquartile range (IQR): 24; 42]. Intraoperative complications occurred in 4 eyes, and 2 eyes had a decentered donor button. Graft failure causing vision impairment and GTE at the final follow-up were noted in 19 (16.2%) and 40 (34.2%) eyes, respectively. Glaucoma prior to DSAEK was significantly associated with GTE [odds ratio (OR) = 6.4; 95% confidence interval (CI) 2.4; 18.3;P= 0.0004]. A history of penetrating keratoplasty (PK) was significantly associated with GTE after DSAEK [OR = 6.2 (95% CI 1.5; 24.7)P= 0.008]. At the last visit, GTE and graft failure were positively associated (OR = 27.2,P< 0.005).

Conclusion:

Escalation of glaucoma therapy was warranted in one in 3 eyes that had undergone DSAEK. GTE and graft failure are interrelated complications. Patients with glaucoma and PK have a higher risk of GTE post-DSAEK.
Workplace Trauma with Massive Intraorbital Foreign Body, A Dramatic Outcome
Authors: Nassim Hala M. , Alam Mohammed H. , Alshuraim Saleh M. , Alfrayyan Abdullah A.
Published: November 2022

Background:

Intra-orbital foreign bodies [IOFB] are considered a rare condition, and an enormous challenge to surgeons, as it might be difficult to diagnose in some cases even with the current advances in imaging technology. Retained IOFB can be a cause of major visual morbidity and blindness, especially in the working population.

Purpose:

In this article, we report a case of IOFB that occurred as a result of workplace related trauma while drilling ceramic.

Methods:

Case report and literature review using PubMed.

Case Presentation:

we present a case of a 30 years old male, not known to have any medical illness, the patient presented to the emergency department after getting trauma while drilling ceramic. Orbital computed tomography [CT] showed multiple high-density objects situated in a circumferential pattern around the globe.

Results:

The patient underwent lateral canthotomy and cantholysis in the emergency department, followed by three exploratory operations to remove intraorbital foreign bodies [FBs]
. Luckily, the patient in our case regained a 0.5 visual acuity, with an impressive improvement in the extraocular muscle motility, with only mild restriction in the upper and lower gazes. The patient was followed up for 2 years after the incident, he was stable during that period.

Conclusions:

IOFB is an ophthalmological emergency, careful history, examination, and investigations are important steps in diagnosing IOFB since it can be easily missed when depending solely on imaging. Timely management is crucial to prevent irreversible complications.

Published: November 2022

Poultry ventures have progressed quickly over the last three decades.
Therefore, curative or growth-promoting antibacterial agents have been utilized
extensively. Because of increasing bacterial resistance towards antibiotics and,
consequently, accumulation of antibacterial residues in chicken products and increased
consumer’s demand for products without antibacterial residues, alternative solutions
that could substitute antibiotics without affecting productivity or product quality should
be attempted. Recently, natural replacements such as ginger, etheric oils, organic acids,
garlic prebiotics, immune stimulants and plant extracts were used to improve
productiveness, and body performance, prevent pathogenic microorganisms, and
reduce antibacterial activity usage in poultry manufacturing. The utilization of a single
alternative or a combination of variable replacements and perfect surveillance and flock

Liquid fuels derived from non-fossil resources are considered feasible
alternatives as global fuel demand rises. Yeast single cell oil is gaining ground as
feedstock for biofuels and oleochemicals over plant-borne or algal oil due to its short
lifespan and invariable quality under different seasonal or geographical conditions. In
the present work, oleaginous yeast Rhodotorula mucilaginosa IIPL32 was genetically
modified to improve its oil-producing capacity by overexpressing malic enzyme, a
reductant providing enzyme active in several oleaginous yeasts. Intracellular Malic
enzyme was purified and characterized to validate its presence and determine its
involvement in lipid synthesis and NADPH+ supply in the yeast R mucilaginosa. Apart from
the pentose phosphate route, it was found that malic enzymes also provided reductants
for lipid biosynthesis in this yeast. A linear expression cassette was created for
selective integration of the malic enzyme under a strong promoter into the yeast genome.
The lipid output was increased 1.18-fold along with significant alteration in its fatty
acid profile. Estimating fuel properties revealed that the total monounsaturated fatty
acids improved from 49% to 66%. The lipid produced by transformed yeast complies with
fuel properties (Density, Viscosity, Cetane number, Cloud point, Pour point) as per the
EU, Indian, and US standards. We conclude that genetically modified yeast lipids could
be a sustainable alternative to using plant-borne oil in biofuel generation. The yeast's
ability to assimilate pentose sugars generated from biomass hydrolysis makes it an
efficient oil platform.

The genus Aurantiochytrium, a heterotrophic marine protist, produces significant
amounts of polyunsaturated fatty acids and carotenoids and is promising as an
alternative source of those lipids. This research aimed to utilize lignocellulosic
biomass, which is abundant on land and does not compete with food supply, for fatty acid
production by Aurantiochytrium limacinum strain SR21. Sugarcane bagasse soaked in
diluted sulfuric acid was blasted by steam explosion and subsequently saccharified by
the enzyme. When SR21 was cultivated in the medium containing saccharified liquid of
sugarcane bagasse, the cell growth was almost abolished as compared with the control
medium with the same glucose concentration, suggesting the presence of growth-inhibiting
components in the saccharified liquid. The growth and fatty acid production of SR21 was
significantly inhibited in the presence of furans and phenolic compounds previously
reported to be generated by heat treatment of lignocellulosic biomass. Among them,
furfural was detected in the bagasse saccharified liquid at the concentration that could
inhibit the growth of SR21. Removal of such compounds by activated charcoal restored the
cell growth and fatty acid productivity.
Development of ISO18363-4 / AOCS Cd29f-2021: A new standardized method to quantify MCPDE and GE in edible oils
Authors:   Loders Croklaan BV, Zwagerman Ralph
Published: November 2022

In August 2021 the International Organization for Standardization (ISO) Â has published part 4 to the ISO 18363 series of methods to quantify MCPD- and glycidyl esters in edible oils. AOCS will follow by publishing the method as AOCS Cd 29f-2021 in 2022. This new method describes a high throughput method for the quantification of these process contaminants, for which the EU has recently updated its legislation on the maximum levels allowed in edible oils. In short, its chemistry is based on fast alkaline transesterification of the fat matrix, which also cleaves the MCPDE and GE esters before the analytes are derivatization and analysis by GC-MS/MS. An in vitro correction for glycidol overestimation, which can occur in alkaline environment, is included.
In the fall of 2018 both ISO and AOCS technical committees agreed to standardize the method in cooperation. An overview is given of the standardization project together with statistical data collected during the collaborative study together with a short introduction to the chemistry of the method.
Serendipitous production of industrially useful p-cymene by catalytic dehydration

As part of our continuing efforts to produce aliphatic polyesters from fats and
oils, we were originally attempting to esterify 9-decenoic acid with perillyl alcohol
[(4-isopropenyl-1-cyclohexen-1-yl)methanol] in the presence of catalytic
para-toluenesulfonic acid in refluxing toluene to give tris-unsaturated perillyl
decenoate as a monomer for subsequent ADMET and thiol-ene polymerization. The
esterification procedure had proven simple and effective for several previous
esterifications involving different alcohol/acid combinations, but in this case the
expected ester was not observed. Instead, a mixture comprised of unreacted perillyl
alcohol and 9-decenoic acid and an unexpected and curiously high amount of p-cymene
(31%; 4-isopropyltoluene) was obtained. With this serendipitous discovery in hand, we
set out to improve the yield of industrially useful p-cymene from perillyl alcohol
utilizing homogenous acid catalysis.Â  We thus report the dehydration and isomerization
of renewable perillyl alcohol as a 3.0 M solution in refluxing toluene to p-cymene in
91.1% yield utilizing catalytic para-toluenesulfonic acid. This approach represents a
bio-based alternative to the conventional petrochemical Friedel-Crafts alkylation of
toluene with propylene, which has several significant drawbacks. Industrial applications
of p-cymene include use as a green solvent, heat transfer medium, ligand for catalysts,
starting material for other industrial chemicals, and as a constituent in fragrances and
perfumes.
Interpretability as a quality parameter for validation of sensor analytics
approaches
Authors:   Aspentech, Flaaten Geir Rune
Published: November 2022

In characterisation of complex sampling matrices like oils, advanced sensors
provide comprehensive results. Solving the challenge of representative and repeatable
measurements provides the analyst with information rich data. To extract the information
from the data and use it in grading or provenance classifications and other analytical
challenges, effective data analytical approaches must be identified and applied. There
are a wide range of possible approaches ranging from traditional multivariate analysis
to the more recently growing field of machine learning approaches. The problem statement
for the data analyst is typically to find the best analytical approach providing the
required insight in an actionable manner. In this paper the main approaches to analysis
of data from advanced sensors are discussed and advice on how to choose the most
effective analytical approach is shared. It is argued that interpretability is one
important and often underestimated quality parameter in the selection process.

Increased prices of energy and uncreditable supplies of fuel have created another
dimension in Business Management. Energy and solvent and chemicals now account between
40 to 50% of total operating costs. Many companies are finding that an organised energy
conservation plan and program can hold down both energy use and costs without disrupting
plant operations. If by energy conversation, you can maintain plant operations, despite
reduction in energy supply, the effect in your profits is obvious.
Co-encapsulation of fish oil with essential oils, lutein, and curcumin to produce
stable fish oil powders with multiple functionalities using ovalbumin-polysaccharide

Marine fish oil is the richest source of long-chain n-3 polyunsaturated fatty
acids (LCn3PUFAs), particularly rich in EPA and DHA, with many health benefits. Lutein
and curcumin are two bioactive compounds that prevent age-related macular degeneration
and provide anti-cancer and anti-inflammatory functions. Directly adding fish oil (FO),
lutein, and curcumin to meat during processing can produce products rich in DHA/ EPA,
lutein, and curcumin and help improve human health without changing consumers' dietary
habits. However, FO, lutein, and curcumin are unstable under processing and storage
conditions and can cause undesirable quality issues such as lipid oxidation and fishy
odor to the meat products. Encapsulation is a common strategy to overcome these
challenges, and essential oils (EO) extracted from spices can mask fishy odor and
inhibit lipid oxidation during encapsulating, processing, and storage. Thus, the FO and
EOs were co-encapsulated first, and then lutein and curcumin were incorporated into the
encapsulate to provide more functions to the final products. All the encapsulated FO-EO
powders were stable at room temperature during the first ten days of storage, but GO
produced the best protective effect among the EOs. Adding lutein or curcumin to the
garlic EO-FO co-encapsulate significantly increased the MDA content in the encapsulation
powders after ten days of storage. Similar results were also observed in the rosemary
EO-FO group. The increased MDA content in the lutein- or curcumin-added FO-EO
encapsulates might be due to the long dissolving time of the lutein or curcumin in the
FO, which allowed prolonged air contacts to the fish oil. The encapsulation efficiency
(EE%) of the final products increased significantly when rosemary and garlic EOs,
lutein, and curcumin were used, but pepper black EO resulted in a decrease in the EE,
probably due to the differences in the polarities of the essential oils.
