С целью создания рентгеноакустического монохроматора с возможностью одновременного управления интенсивностью и угловым положением рентгеновских лучей изучены распределения полуширины и интенсивности пиков кривой качания вдоль поверхности монокристалла кварца от отражающих атомных плоскостей (112ത0) в симметричной геометрии Лауэ при наличии продольных и поперечных акустических колебаний. Показано, что возможно одновременное возбуждение взаимно перпендикулярных акустических волн в единственном кристалле-резонаторе с сохранением возможности управления параметрами рентгеновского пучка с помощью каждого из типов колебаний. При этом поперечные колебания «по толщине» кристалла дают возможность управления интенсивностью дифрагированного излучения, а продольные колебания «по длине» дают возможность осуществления контролируемой угловой перестройки дифрагированного пучка.

Novel method for distinguishing the fresh meat and the meat treated by KNO3 by using automatic measurement of bioimpedance analysis
Authors: Dang Thanh Trung , Nguyen Phan Kien , Nguyen Thanh Trung
Published: May 2022

Pork meat that treated by KNO3 looks like fresh one that human eyes cannot classify in the real life. The consumption of spoiled meat that treated by KNO3 will make a higher chance to get cancer in human body because of the changing from Nitrate to Nitrite inside the body. The automatic impedance measurement of meat has been developed and showed that this system can detect the existing of KNO3 inside the meat. In the system, pork meat is considered an electronics circuit that approved by two models: Fricke and Cole-Cole. By using an inverting amplifier with the piece of meat located at the feedback part of the circuit, the sinusoidal signal generated by the AD9850 module will be passed through the circuit. The signal received from the output of AD9850 will be sent to the oscilloscope and uploaded to the computer, and automatically change the frequency range of the generated signal to investigate the complex impedance of the meat in the frequency range from 10 Hz to 1 MHz. The obtained results will be analyzed by Levenberg-Marquart algorithm, showing that the distinction of fresh meat and meat that has been treated with KNO3 can be determined by the phase-frequency spectrum and amplitude of impedance of meat at low frequency (100 Hz). In the future, the system will be  upgraded and apply for the real life.

With the growth and accessibility of the internet to everyone, recognizing pornographic images is of great significance for protecting children's physical and mental health. It’s common for children to surf the internet and they are just one click away from getting access to pornographic images. It is the desire of all parents to protect their children from online pornography, cyberbullying, and cyber predators. Several existing methods analyze a limited amount of information from a child's interaction with the respective online section. Some restrict access to sites based on blacklists known as banned URLs, others attempt to scan and analyze media content being exchanged between two parties. However, new URLs can be used to bypass blacklists, and images, videos, and text appear to be safe individually but should be evaluated together. Due to the vast size of social media- generated content, these approaches are insufficiently accurate. Furthermore, the approaches are not discriminative enough on a variety of image properties. The Colour, shadow, and frequency features of the images can vary, even the context is the same according to lumination features. The problem can be solved more accurately with deep learning techniques. Notably, the specific type of deep learning architecture called convolutional neural network is suitable for the problem space. Having a potential solution becomes even more important than detecting and recommending NSFW (Not Safe For Work) content that may be present to the user.

Authors: Cruz-González Cristina , Rodríguez Carmen Lucena , Mula-Falcón Javier
Published: May 2022

The global pandemic of the COVID-19 has caused numerous challenges and obstacles in the museum sector. Due to social and mobility restrictions, museums have had to adapt their services to virtual scenarios in record time. In this article we explore the different initiatives developed in various geographical locations around the world and investigate the various barriers and limitations that museums have experienced in dealing with this pandemic. In addition, we explore the different lines of current research that address this issue and analyze the educational and professional implications that can be drawn from this health and social crisis. Some of our main findings reveal the importance of digital education and training of the museum's professional staff. They also highlight the big role played by social networks as a resource to bring the museum closer to the audience in times of coronavirus. Finally, we argue for a greater political effort to guarantee the digitization of museums that do not have sufficient resources in times when access to culture is mainly online.

Published: May 2022

The base metal alloys are more susceptible to corrosion than nobl ealloys, and fixed orthodontic appliances are generally made of base alloys. Fixed orthodontic appliances in the oral cavity are exposed to destructive physical and chemical agents, resulting in metallic corrosion. The present study aimed to evaluate the concentration of cobalt, zinc, and magnesium in patients' saliva with fixed orthodontic appliances at three different times. Saliva samples from 18 patients (9 males and 9 females) between 15-25 years were taken at three different time points. Group I: Pretreatment saliva sample, group II: one month after appliance placement, Group III: four months after appliance placement. The fixed appliance consists of 20 stainless steel brackets, 4 buccal tubes, and a super elastic nickel-titanium arch wire. Inductively Coupled Plasma Optical Emission Spectrometry analyzed the level of ions in salivary samples. Ions are recorded in parts per billion. Statistical analysis was performed by non-parametric tests (Friedman) and one-way repeated measures ANOVA. Levels of cobalt, magnesium, and zinc ions in saliva were highest in group II, lowest in group I for both zinc and cobalt, and lowest in group III for magnesium. On a pair wise comparison between different groups, it was statistically significant for all groups (<0. 005) except for cobalt and magnesium level between group I and group III and zinc level between groups II and III. Cobalt, magnesium, and zinc levels in saliva were increased after placing a fixed orthodontic appliance.

Anemia is a problem experienced by 41.8% of pregnant women worldwide. Riskesdas data 2018 on pregnant women in Indonesia with Anemia is 48.9%. Anemia in pregnant women can be multifactorial, from pure iron, folate, B12 deficiency, and malaria/hemolytic or sickle cell disease. Anemia in pregnancy is influenced by poverty, lacking nutritional intake, gender inequality, and ignorance about the proper diet. Pregnant women need many nutrients to meet the body's needs for themselves and their fetuses. For pregnant women, anemia plays a role in increasing the prevalence of maternal mortality and morbidity. The study aimed to analyze the prevalence and risk of anemia during pregnancy. The new thing in this study is that research conducted using the baby's chest circumference variables and the length of the baby's body was also investigated. Of the 50 babies studied, 2 were born with a head circumference < 33 cm, and 3 were born with a length < 48cm. After being processed with the baby's weight, the results showed no relation between the baby's chest circumference and weight. This study used a retrospective cohort with a sample of 50 mothers with 1-year-old children in the city of Semarang. There is a relationship between the status of newborns, gestational age, length of the baby's body, and the frequency of ANC. At the same time, the variables that did not exist with the status of the newborn were education level, consumption of Fe tablets, Hb TM I, Hb TM II, and Hb TM III. These results are expected as input for the Health Office to enhance outreach activities evenly to pregnant women.

Published: May 2022

The Tanimbar Corella (Cacatua goffiniana) is a protected bird species endemic to the Tanimbar Islands (Yamdena and its satellite islands) in the Maluku province of Indonesia. The major threats identified to this species are hunting, illegal trade, and habitat loss. Therefore, this study aims to classify the land cover, distribution, and habitat types occupied by C. goffiniana on the Tanimbar Islands. Classification of land cover was analyzed using a supervised classification method of the Erdas Imagine 2014 software. Direct field observations were conducted to identify the distribution of Tanimbar Corella and its habitat use. The land cover was classified into six classes: forest (54.26 %), open area (20.76%), plantation (14.81%), mangrove (6.89%), settlement (1.85%), and wetland (1.43%). C. goffiniana is distributed on five islands, Yamdena, Selaru, Larat, Sera, and Molu. Furthermore, this species was observed in forest, plantation, and open land habitats. The results identified seventeen nest trees of six species: Canarium Indicum, Pometia pinnata, Instia bijuga, Sterculita foetida, Maranther corymbosa, and Alstonia scholaris, with a range diameter of 40.00-136.71 cm and nest cavity heights of 9.00-34.22 m (n = 17). This research brings new data in three areas: 1) a reassessment of the distribution of C. goffiniana on the Tanimbar Islands; 2) a detailed classification of the land cover concerning habitat types of the Tanimbar Islands; 3) an identification of the tree species utilized by nesting Tanimbar Corellas. Information on preferred habitats and nesting trees is crucial for selecting release sites of confiscated birds to ensure post-release survival.

The Danube-Carpathian region represents one of the most preserved natural habitats for wildlife species in Europe. It is the last European great wilderness area, a stronghold for large carnivores, and home to the large remaining reserves of old-growth forests. Achieving ecological connectivity of the area is an inevitable part of its protection. Therefore, ecological corridors, which play a wide range of roles such as protecting endangered species and the biodiversity of territory, and securing its eco-connectivity while facilitating various ecosystem services, need to be thoroughly identified, managed and protected. That can contribute to avoiding landscape fragmentation and preserving the environment, including the endangered animal species. However, a comprehensive and coordinated ecological corridor identification, management, and preservation system within this region are missing, and the concerned countries meet with diverse problems when dealing with the issue. That creates one of the key problems in protecting these valuable natural areas. In order to identify the main gaps in the planning processes and tools related to the ecological corridors, broad analytical work has been undertaken supported by the questionnaire, carried out in the concerned 5 countries located in the Danube-Carpathian region. The paper's objective is to identify the gaps in the identification, management, and preservation of ecological corridors' involvement of the public in the processes such as integration of ecological networks into spatial planning in legal processes. The outcome of the study thus contributes to establishing an integrated approach for strengthening the capacity for identifying, managing, and protecting ecological corridors and helps to overcome the conflict between infrastructure development and wildlife conservation. The paper's novelty lies in the scope and breadth of the analysis, covering 5 Carpathian countries and stakeholders from various sectors under the umbrella of EU funded Interreg DTP Project.

Accordingly, a country's stock market and credit market are extremely important in giving impetus to technological innovation. Thus, we construct a panel data model with interactive fixed effects to study the impact of stock market development and credit market development on technological innovation in countries at different levels of economic development. Results indicate that, whether for developed or developing and emerging market countries, the development of the stock market has a significant positive influence on national technological innovation (NTI), and the impact of the development of the credit market on innovation of different types of countries is quite different. In addition, foreign direct investment (FDI) inflow can increase the positive impact of stock market development on NTI, but this impact is not significant for the sample of developed countries.
An Overview on Insect Tolerance Transgenic Crops
Authors: Kumar Dr. Prafull , Nandan Durgesh
Published: May 2022

Although transgenic crops have enhanced insect pest control, their effectiveness has diminished due to pest resistance. Humans examined global monitoring data from the very first two decades of genetically engineered crops, with each occurrence representing one pest species' response to one Bacillus thuringiensis insecticidal protein in one country (Bt). Pest tolerance to transgenic crops' Bt crystalline (Cry) proteins has increased from three cases in 2005 to sixteen cases in 2016. Hereditary change that is bug-free innovation is fastgrowing, with enormous exploration effort in both the commercial and legislative regions. Although the bacterium Bacillus thuringiensis is the most widely advertised bug-safe transgenic plant, a wide range of traits from higher plants, particularly those producing stomachrelated chemical inhibitors or lectins, have also been introduced into crop cultivars. So far, the quality of opposition from various microbes and species has only been used in a few circumstances.

Modern era has developed many ways to study about black holes. The study of Kawai, Matsuo, and Yokosuka has demonstrated that Is when back-reaction of Turing rays is considered, the collapse of mass does not result in a perimeter or an optical horizon. In this article, we relax their assumptions and go further into the air shape of a universal collapsing body has hexagonal symmetry. Since this morphology outside the expanding orb is approximate by the geometric outside light skinned horizon, the collapsing on here outside Schwarzschild region. As molecules in Darwin rays are created in the area of contracting matter, the problem of data leakage is alleviated. There is no event horizon if the collapsing body vanishes in a limited amount of time.
An Overview of On-Farm Hygienic Milk Production

- The dairy sector has adopted hazard analysis of critical control points (HACCP) systems to ensure the food safety of dairy products. Through a chain management strategy, this allows for quality verification of final goods (European Commission, 2004b). Raw milk's quality and safety are critical for milk and the dairy products' safety and quality. Milk contamination with bacteria, chemical residues, and other pollutants affects the safety and quality of the products. Microbial contamination is the subject of this chapter. Salmonella spp, Listeria monocytogenes and Campylobacter jejuni are examples of human microbial pathogens discovered in raw milk. A very high microbiological quality of raw milk is essential for preventing process losses and achieving an optimum shelf life for dairy products, in addition to its importance for the public health. For example, faults in semi-hard cheeses are caused by the spore formers of butyric acid bacteria in the raw milk, and raw milk contamination with Bacillus cereus bacteria reduces the shelf life of pasteurized dairy products. Quality assurance methods for dairy farms are being created, and bacteriological structures are being used in farms bulk of raw milk payment systems, in order to guarantee that bulk tank milk has a high microbiological quality. Furthermore, dairy producers' sanitary milk production is critical for animal’s welfare and dairy industry's image. Infections of pathogenic microorganisms affect cows (e.g., udder tissue, gastrointestinal tract), resulting in lower milk production and even mortality. In conclusion, all components of the dairy production chain benefit from the management of the microbial ecology at the dairy farm, which leads to on-farm hygienic milk productions.
A Real Time Tracking System for School Forms Using QR Codes with Watermarking Algorithm
Authors: Rimando Mark Kevin V.
Published: May 2022

Document tracking is considered crucial, particularly in schools that still use traditional administration methods. Meanwhile, the usage of forms in a school's office, such as the Budget Division, is still necessary and should not be removed as per the school’s current policy. As a result, the school should have a solid monitoring system in place to ensure that these forms are stable and reliable. The tracking system is a flexible solution that may be used as a collaboration and communication tool, and it can aid in the construction of a traceable process. The researcher investigates the school's key concerns regarding using paper-based forms, as well as how the school can track its progress and location. The usage of a watermarking algorithm and a QR code-based tracking system was explored in this study. In addition, the structure, applications, security, and strategies for using a QR code are discussed. Existing watermarking technology, according to relevant research, has the opportunity for development in terms of imperceptibility and endurance in the future.
