The type of androgenetic alopecia and quality of life (QoL) in male patients

Androgenetic alopecia (AGA) is a nonscarring baldness that mostly affects >50% men worldwide. Hair loss led to psychological difficulties and have a negative impact on the quality of life (QoL). This study aimed to evaluate the relationship between the type of AGA and QoL in male patients. A total of 67 male AGA patients were clinically assessed using the Hamilton-Norwood scale and interviewed using the Hair-Specific Skindex-29 scale to assess QoL. The patients were predominantly in the age group 31-50 years (50.7%), mean age 49.60 years, grade I obese (32.8%), mean BMI 24.93 kg/cm2, 41.8% with father’s AGA history, smoking (62.7%), smoking >100 cigarettes in last 6 months (41.8%), and have hypertension (16.4%) and diabetes mellitus (3%) as concomitant diseases. Based on Noorwood-Hamilton scale, the types of AGA were predominantly type II (25.4%) and followed by type III (16.4%). The results of the Hair Specific Skindex-29 on AGA patients were moderate (58.2%) and severe (41.8%). There were a relationship between AGA type and QoL (p = 0.041) and significant positive correlation between AGA type and QoL (p = 0.020, r = 0.282). In conclusion, patients experienced moderate to severe impact on QoL due to AGA.

Effect of transverse magnetic field on magnetogasdynamic flow and heat transfer characteristics in insulated / conductive circular tubes

The regulating effect of magnetic field on magnetogasdynamic flow and heat transfer characteristics in circular tubes has important applications in many fields, but there is still a lack of relevant basic research. Considering the conductivity of the tube wall and the insufficient development of turbulence, the physical model and mathematical model of magnetogasdynamic flow in a circular tube under a given transverse magnetic field are constructed, and the numerical algorithm is designed within a theoretical framework of the finite volume method. The effect of factors including Hartman number (&lt;i&gt;Ha&lt;/i&gt;) and wall conductivity ratio (&lt;i&gt;C&lt;/i&gt;) on the flow and heat transfer characteristics are obtained through analyzing the distributions of velocity, turbulent kinetic energy, and temperature. Furthermore, the regulation mechanism of the transverse magnetic field is discussed by analyzing the spatial distribution of induced current, electromagnetic force and Joule heat. The results show that the distribution of velocity and the distribution of turbulent kinetic energy in the circular tube under a given transverse magnetic field are both anisotropic. The turbulent kinetic energy near the Hartmann boundary layer is much lower than that near the Roberts boundary layer, and the anisotropic distribution of velocity and turbulent kinetic energy become more and more evident with the increase of &lt;i&gt;Ha&lt;/i&gt; and the extension of the flow. The transverse magnetic field has a suppression effect on the heat transfer in the tube. For different values of &lt;i&gt;C&lt;/i&gt;, the average Nusselt number (&lt;inline-formula&gt;&lt;tex-math id="M1"&gt;\begin{document}$ \overline {Nu} $\end{document}&lt;/tex-math&gt;&lt;alternatives&gt;&lt;graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="16-20220051_M1.jpg"/&gt;&lt;graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="16-20220051_M1.png"/&gt;&lt;/alternatives&gt;&lt;/inline-formula&gt;) shows a first-decreasing-and-then-increasing trend with &lt;i&gt;Ha&lt;/i&gt; increasing, that is, there is a “saturation effect” in heat transfer suppression.

The change of flow characteristics in the circular tube results from the variation of electromagnetic force under the coupling of magnetic field and fluid, while the change of heat transfer characteristics originates from the coupling effect of the suppression of turbulence and the Joule heating.

Continuous monitoring of the health status of cement-based structures: electrical impedance measurements and remote monitoring solutions

&lt;p class="Abstract"&gt;The continuous monitoring of cement-based structures and infrastructures is fundamental to optimize their service life and reduce maintenance costs. In the framework of the EnDurCrete project (GA no. 760639), a remote monitoring system based on electrical impedance measurements was developed. Electrical impedance is measured according to the Wenner’s method, using 4-electrode arrays embedded in concrete during casting, selecting alternating current as excitation, to avoid the polarization of both electrode/material interface and of material itself. With this measurement, it is possible to promptly identify events related to contaminants ingress or damages (e.g. cracks formation). Conductive additions are included in some elements to enhance signal-to-noise ratio, as well as the self-sensing properties of concrete. Specifically, a distributed sensor network was implemented&lt;span style="text-decoration: line-through;"&gt;,&lt;/span&gt; consisting of measurement nodes installed in the elements to be monitored, then connected to a central hub (RS-232 protocol). Nodes are realized with an embedded unit for electrical impedance measurements (EVAL-AD5940BIOZ board with AD5940 chip, by Analog Device) and a digital thermometer (DS18B20 by Maxim Integrated), enclosed in cabinets filled with an IP68 gel against moist-related problems. Data are available on a Cloud through Wi-Fi network or LTE modem, hence can be accessed remotely via a use-friendly multi-platform interface.&lt;/p&gt;

Changes in technology and civilization—A conceptual study of the Metaverse

&lt;p class="15" align="justify"&gt;Advances in media technology continue to drive changes in the shape of human society, and human civilization has stepped into the eve of the Metaverse. Based on this practical background, this paper analyzes the Metaverse concept from three aspects: the proposed background, construction and characteristics of the Metaverse, and analyzes and summarizes the impact of the Metaverse on the current situation of the industry and the future of the industry. This paper argues that the proposal of &lt;span style="font-family: 'Times New Roman';"&gt;M&lt;/span&gt;etaverse is the inevitable development of society and technology, and the endgame of Internet development. The &lt;span style="font-family: 'Times New Roman';"&gt;M&lt;/span&gt;etaverse is a product of the constant innovation of the medium and has evolved from the possible worlds in literature to video games. This paper summarizes the basis of &lt;span style="font-family: 'Times New Roman';"&gt;M&lt;/span&gt;etaverse construction from the perspective of humanities and technologies, and proposes that the &lt;span style="font-family: 'Times New Roman';"&gt;M&lt;/span&gt;etaverse will develop a virtual civilization in terms of humanities, and be supported by both software and hardware technologies in terms of technologies. On the basis of this foundation, it is extracted that the &lt;span style="font-family: 'Times New Roman';"&gt;M&lt;/span&gt;etaverse has two characteristics: civilization and intersectionality. This paper summarizes the influence of &lt;span style="font-family: 'Times New Roman';"&gt;M&lt;/span&gt;etaverse on industry, mainly including the influence of &lt;span style="font-family: 'Times New Roman';"&gt;M&lt;/span&gt;etaverse on the current layout of industry and the influence on the future development of industry. The concept and impact of &lt;span style="font-family: 'Times New Roman';"&gt;M&lt;/span&gt;etaverse and its commercial application in industrial development proposed in this paper lay the corresponding theoretical foundation for the subsequent research on &lt;span style="font-family: 'Times New Roman';"&gt;M&lt;/span&gt;etaverse.&lt;/p&gt;

Kelimpahan Dinoflagellata Bentik Berbahaya di Habitat Lamun dan Makroalga di Pulau Pari, Kepulauan Seribu, Indonesia

&lt;p class="Papertext"&gt;&lt;strong&gt;The Abundance of the Harmful Benthic Dinoflagellate in the Seagrass and Macroalgae Habitats on Pari Island, Thousand Islands, Indonesia. &lt;/strong&gt;Benthic dinoflagellates are an important part of benthic ecosystems and part of their ecological functions. However, ciguatoxin (CTX) producer dinoflagellates, which could cause Ciguatera Fish Poisoning (CFP) disease, is a known threat to marine biota and the island’s coastal communities, such as in Pari Island. Thus, this research aimed is to study the population of five harmful and toxin producer benthic dinoflagellate genera, namely &lt;span style="text-decoration: underline;"&gt;Amphidinium&lt;/span&gt;, &lt;span style="text-decoration: underline;"&gt;Coolia&lt;/span&gt;, &lt;span style="text-decoration: underline;"&gt;Gambierdiscus&lt;/span&gt;, &lt;span style="text-decoration: underline;"&gt;Ostreopsis&lt;/span&gt;, and &lt;span style="text-decoration: underline;"&gt;Prorocentrum&lt;/span&gt;, in macroalgae and seagrass habitats of Pari Island. Benthic dinoflagellate samples were collected in Juni 2019 using artificial substrates in the form of a 10×15 cm nylon screen. Environmental variables, such as nutrient concentration (nitrogen and phosphorus) and water temperature were also measured. The results showed that the average benthic dinoflagellate density in seagrass habitats was four times higher compared to the macroalgae habitats. &lt;em&gt;Gambierdiscus&lt;/em&gt; were found as the most abundant benthic dinoflagellate in seagrass habitats, while &lt;em&gt;Prorocentrum&lt;/em&gt; were more abundant in macroalgae habitats. Principal Component Analysis (PCA) showed that the N:P ratio was the most important regulating parameter for most benthic dinoflagellate genera in this study, except &lt;em&gt;Ostreopsis&lt;/em&gt;, which was found to be more abundant in phosphorus-rich macroalga habitats. The data also shows an increase of benthic dinoflagellate cell density up to seven times compared to the previous research data in 2012 and 2013. That trend indicates an increase in the disturbance and pressure on the macroalgae and seagrass habitats of Pari Island, which require special attention to prevent the occurrence of toxic Benthic Harmful Algal Blooms (bHABs) and CFP cases in the island.&lt;/p&gt;

Metaverse technology: Promoting freedom and comprehensive development of human beings

&lt;p&gt;People are living beings who desire to maximize the value of life. The value of an individual's life requires the practice of labor to be manifested. However, human beings always face constraining conditions that limit the maximization of life value. First, the span of human life (time) is limited. Restricted by class, occupation and role, it is difficult for individuals to accomplish more tasks in their limited lives; secondly, social resources, i.e. labor opportunities, are limited. As the productivity of society increases and robots appear in large numbers, the total labor opportunities of society gradually decrease. The &lt;span style="font-family: 'Times New Roman';"&gt;Metaverse&lt;/span&gt; technology solves these two limitations. First, the &lt;span style="font-family: 'Times New Roman';"&gt;Metaverse&lt;/span&gt; allows individuals to experience more diverse and richer life experiences as much as possible within the limited length of life. Secondly, the &lt;span style="font-family: 'Times New Roman';"&gt;Metaverse&lt;/span&gt; provides more workplaces and labor opportunities through the creation of a pluralistic virtual society. The &lt;span style="font-family: 'Times New Roman';"&gt;Metaverse&lt;/span&gt; manifests and practices the value of individual life, promotes the free and comprehensive development of human beings, and is an effective “ultimate care” that can play a constructive role in society.&lt;/p&gt;

This study aims to see how to see members who are online arisan, see which ones contribute to online arisan in fulfilling student lifestyles, and see a review of Islamic economics on online social gathering activities in the Islamic economics faculty of the State Islamic University of North Sumatra. The research method used a qualitative approach with data techniques, namely primary data and secondary data. Research subjects, the owner of the arisan and (9) members of the online arisan. Data techniques are premier data and secondary data. The data analysis methods used in the study were data reduction, data presentation, and conclusion drawing. The results of this study indicate that the lifestyle of students who take part in an online social gathering is classified as hedonistic, the contribution of online arisan to the arisan group is that there are many benefits obtained by members and an Islamic economic review of the online social gathering system is not allowed because it contains elements of usury in it.&lt;/span&gt;&lt;/em&gt;&lt;p class="MsoNormal" style="margin-top: 0cm; margin-right: 0cm; margin-bottom: .0001pt; margin-left: 13.55pt; text-align: center; text-indent: -13.55pt; line-height: 112%;" align="center"&gt;&lt;strong&gt;&lt;span style="mso-bidi-font-size: 12.0pt; line-height: 112%; font-family: 'Garamond','serif';" lang="IN"&gt;KONTRIBUSI ARISAN ONLINE DALAM MEMENUHI GAYA HIDUP MAHASISWA MENURUT SUDUT PANDANG EKONOMI ISLAM&lt;/span&gt;&lt;/strong&gt;&lt;/p&gt;&lt;h1 style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 10.0pt; margin-left: .5pt; text-align: center;" align="center"&gt;&lt;span style="mso-bidi-font-size: 12.0pt; line-height: 107%; font-family: 'Garamond','serif';" lang="IN"&gt;(Studi Kasus Pada Kelompok Arisan Mahasiswa Fakultas Ekonomi Dan Bisnis Islam Universitas Islam Negeri Sumatera Utara)&lt;/span&gt;&lt;/h1&gt;

Effects of Harvesting Period on Phytochemicals of Wheatgrass (Triticum aestivum, WK 1204 Variety)

&lt;p class="MsoNormal"&gt;&lt;span style="color: black; mso-themecolor: text1;"&gt;Wheatgrass&lt;/span&gt; is a plethora of essential phytochemicals considered to exhibit numerous benefits on human health. Therefore, the study of phytochemicals with varying stages of growth is essential. This study aims to determine the optimum harvesting period of wheatgrass based on its phytochemical content. During the growth of wheat seed (WK 1204 variety), the phytochemicals such as chlorophyll, total phenol content, flavonoids and tannins were extracted by 80% acetone and 80% methanol from wheatgrass harvested on days 6, 7, 8, 9 12 and 15, respectively. &lt;span style="background: white;"&gt;2,2-diphenyl-1-picrylhydrazyl&lt;/span&gt; (DPPH) radical scavenging activity, chlorophyll and flavonoid contents significantly (p&amp;lt;0.05) increased and reached the maximum level on day 9. Total phenol content was found to be increasing significantly (p&amp;lt;0.05), while the tannin content was decreasing considerably (p&amp;lt;0.05) on day 15. The optimum harvesting period was found &lt;span style="mso-ansi-language: IN;" lang="IN"&gt;on&lt;/span&gt; day 9. The DPPH radical scavenging activity, chlorophyll and flavonoid content significantly (p&amp;lt;0.05) increas&lt;span style="mso-ansi-language: IN;" lang="IN"&gt;ed&lt;/span&gt; and reached the maximum level, i.e., 92.27±1.92%, 6.63±0.053 mg g&lt;sup&gt;&lt;span style="mso-ansi-language: IN;" lang="IN"&gt;-1&lt;/span&gt;&lt;/sup&gt; and 183.64±33.49 mg QE g&lt;sup&gt;&lt;span style="mso-ansi-language: IN;" lang="IN"&gt;-1&lt;/span&gt;&lt;/sup&gt;, respectively, on day 9 of cultivation. The total phenol content was found to be increasing significantly (p&amp;lt;0.05) from 291.67±5.69 mg GAE g&lt;sup&gt;&lt;span style="mso-ansi-language: IN;" lang="IN"&gt;-1 &lt;/span&gt;&lt;/sup&gt;on day 6 to 446.67±5.77 mg GAE g&lt;sup&gt;&lt;span style="mso-ansi-language: IN;" lang="IN"&gt;-1&lt;/span&gt;&lt;/sup&gt; on day 15, while the tannin content was declining significantly (p&amp;lt;0.05) from 11.74±0.29 mg GAE g&lt;sup&gt;&lt;span style="mso-ansi-language: IN;" lang="IN"&gt;-1&lt;/span&gt;&lt;/sup&gt; on days 6, 7 and so on to 3.36±0.47 mg GAE g&lt;sup&gt;&lt;span style="mso-ansi-language: IN;" lang="IN"&gt;-1&lt;/span&gt;&lt;/sup&gt; on day 15. Therefore, the optimum harvesting period of wheatgrass was found to be day 9 in terms of phytochemical analysis.&lt;/p&gt;

Collaborative decision-making on preservation cost control of litchi supply chain in Zhangzhou

&lt;p&gt;Litchi is a kind of fruit with high demand for freshness, and the freshness of litchi is lost very quickly. There is no cooperative decision -making mechanism for litchi supply chain in Zhangzhou&lt;span style="font-family: 'Times New Roman';"&gt;,&lt;/span&gt; and the members of the supply chain make decisions independently in most cases. The members of the supply chain make decisions based on their own interests, so that the freshness of litchi cannot be well controlled, and the overall benefit of litchi supply chain cannot be maximized. On the basis of analyzing the supply chain structure and the preservation cost of litchi supply chain in Zhangzhou, this paper demonstrates the necessity of collaborative decision-making on preservation cost control of litchi supply chain in Zhangzhou through an example, and put forward to implement the collaborative decision-making on preservation cost control of litchi supply chain in Zhangzhou by constructing the collaborative decision-making platform of litchi supply chain in Zhangzhou.&lt;/p&gt;
