Authors: Adhi Tri Partono , Nurfebriartanto Aditya , Indarto Antonius , Kariem Muhammad Agus
Published: June 2023

Metode absorpsi merupakan metode yang banyak digunakan dalam pemurnian gas alam dari senyawa pengasamnya. Unit pemisahan senyawa sulfur pada PT BCD dirancang untuk menurunkan konsentrasi H2S pada gas alam dari 9957 ppm menjadi kurang dari 10 ppm dengan laju alir gas umpan pada rated condition adalah 327,7 MMSCFD. Keseluruhan sistem pengolahan gas didesain dengan turndown ratio 40%. Karena alasan operasi, laju alir gas umpan perlu diturunkan hingga 20% kapasitas desain (65,54 MMSCFD). Analisis dilakukan untuk mengetahui perilaku hidrodinamik kolom absorber dan sistem pendukungnya pada pengoperasian di 20% kapasitas desain. Simulasi dilakukan menggunakan perangkat lunak ASPEN HYSYS V11 untuk mengetahui parameter operasi kolom absorber dan kondisi untuk mendukung pengoperasian di 20% kapasitas desain. Dengan desain operasi peralatan saat ini, weeping terjadi pada laju alir gas umpan 28% desain (91,59 MMSCFD). Pada laju alir gas umpan 28% desain, wash water pump sudah mencapai kapasitas minimum, yaitu 78 gpm. Semakin kecil laju alir gas umpan, maka laju sirkulasi wash water perlu dikurangi untuk menghindari weeping. Untuk dapat beroperasi di gas umpan 20% desain, kapasitas wash water pump perlu diturunkan hingga 25 gpm.

Industri kimia dan juga termasuk di dalamnya, industri semen, menghadapi tantangan untuk dapat terus melakukan perbaikan proses untuk melakukan efisiensi sumber daya dan meminimalkan beban pencemaran ke lingkungan. Salah satu hal yang penting di industri semen adalah kandungan SO2 pada emisinya. Kandungan emisi ditentukan oleh proses pengolahan gas, yang dilakukan dengan penyemprotan air di gas conditioning tower (GCT) dan bag filter sebelum dikeluarkan ke lingkungan melalui cerobong. Di sisi lain, konsumsi air di GCT merupakan salah satu titik penggunaan air yang tertinggi di industri semen. Studi ini bertujuan untuk menganalisis efisiensi penggunaan air di GCT dengan menggunakan seven tools mulai dari analisis masalah hingga pembuatan usulan standard operating procedure (SOP) baru. Dari analisis ini didapatkan bahwa tergantung pada kadar SO2 dan SO3 di emisi dan bahan baku, maka dapat dilakukan pengendalian temperatur inlet bag filter yang selanjutnya akan mengendalikan volum air di GCT. Hasil pengembangan/inovasi ini menunjukkan bahwa SOP baru dapat menghemat air di GCT secara signifikan.
A Study on Integrating Cultural Signs of “Global Village” into Cultivating Chinese English Major Students’ Foreign Language Competence with the Vision of Global Community of Shared Future
Authors: HU Dongxue , JIN Hanyu , Li Yi , CUI Dan
Published: June 2023

The fundamental task of cultivating foreign language talents in the new era is to cultivate talents. English major students are supposed to have solid Chinese language skills and cultural knowledge, to be able to skillfully apply language teaching skills related to foreign languages, and have the competence to adopt foreign languages for cross-cultural communication. This article aims to study the “global village” as a unique language practice base of Jilin International Studies University and integrate it into the instruction of higher education to nurture talents for international communication. Based on exploring the connotation of cultural signs that highlights the “global village” and their application of them in cultivating English major students’ foreign language competence, we intend to improve English major students’ humanistic and cultural literacy to nurture their sense of self-national identity under the internationality of globalization. Thus, they are prepared to possess the comprehensive language competence constituted mainly by the broad vision, international consciousness, global village outlook, and cross-culture consciousness and competence, etc. which will necessarily help them to actively and effectively participate in international communication and eventually dedicate themselves to constructing a global community with a shared future for mankind, which essentially makes up the core of cross-cultural competence.
Obsidian lithic technology: Chaîne opératoire and symbolic meaning in the Northern Hualfín Valley (Northwest Argentina) during the Late Inka period
Authors: Bentivenga Emiliano , Lynch Julieta
Published: June 2023

The main objective of this research is to analyse the lithic technology applied to obsidian, a raw material popular amongst pre-Columbian populations from Northwestern Argentina (NWA) because of its social and symbolic value. The analysed assemblage comes from the archaeological site of Villavil 2 (VV2), located in the Hualfín Valley (Catamarca, Argentina) and distant ca. 100 - 200 kms from the nearest sources of this raw material. VV2 was discovered in 2015 by one of the authors and shows a particular presence of rock art which had not previously been registered in this area. The site was associated to the Late and Inka Period (ca. 10th - 16th centuries CE). So far, we suggest that this was a place of temporal, but periodical use that best fits with what we would call a ceremonial space.
The assemblage comprises the totality of obsidian elements collected from both superficial and stratigraphic contexts. It was divided into three typological classes: tools (projectile points), flakes with natural sharp edges (FNSE) and waste products (WP). We did not identify the presence of cores. The analysis considered the following variables: knapping methods and techniques, size, amount of cortex, flake type and edge types.
At VV2, points are the only retouched tools made of obsidian. They correspond to the triangular unstemmed concave-based type, very common during the Late-Inka Periods, and they were shaped using the perimetral bifacial pressure technique, possibly from flake blanks. FNSEs’ size is small, and they present scarce cortex. On the other hand, the abundance of very small-sized WPs is remarkable. They were found in the same stratigraphic context and attest a complete finish of the points (edge retouch).
The results let us infer that the point-shaping tasks were carried out in situ. Moreover, the implemented technology involved both major production efforts and skills, that contrast with those involved in local raw material knapping. It is possible that this curated strategy was not related to the difficulty of accessing this allochthonous material. Instead, these choices could reflect social and symbolic meanings. According to linguistic and ethnohistoric information, the obsidian brightness and transparency are propitiatory to win the favour of the w'akas. Furthermore, in NWA the obsidian long-distance exchange is an ancient pre-Columbian tradition that lasted for a long time. Obtaining obsidian could display the ability of a social group to access distant resources and legitimize their political status. Nevertheless, we cannot forget that this raw material also was very important for making different artefacts for subsistence activities.
Livable Streets - Impact of Pedestrianisation in Establishing Social Interactiveness on Commercial Streets of Delhi
Authors: Verma Rajat , Gahletia Komal
Published: June 2023

Abstract: From ancient times, streets have been the designated urban spaces for people to celebrate different activities like festivals, political protests, selling- purchasing goods, etc. The streets are the public realm which should have people its first priority. The street design has shifted their centre from people and social spaces to vehicular congestion solutions. The augmentation of vehicular movementson streets have shattered the urban livable environment of a street and converted these public realm for a vehicular movement only. The research is around the commercial streets of Delhi. The Research will begin by understanding the unfavorable conditions for pedestrians on commercial streets and impact of pedestrianisation in improving such conditions. The motive is to hierarchically re-orient the street in order to create a sense of place that fosters social interaction. Various elements of a street including furniture, neighborhoods, etc will be studied and the influence of these elements on the overall urban life of a street to encourage livable walkable space for pedestrians will be drawn. Depending on case studies, surveys and observations, ways of making these streets interactive and livable for pedestrians will be studied. From aforementioned work, some modules and sections will be proposed on the basis of the context of Delhi. Ultimately, the paper will conclude the set of modules that encourages the pedestrian activities rather than vehicular movement.

iCap: A Low-Cost Cap for Visually Impaired
Authors: Dar Rameez Ahmad
Published: June 2023

Abstract: The boom in science and technology has significantly contributed towards the welfare, comfort and ease of movement of mankind, more so for the specially-abled sections of society. Though smart canes are considered to be the cutting-edge technology in terms of improving the lifestyle of visually impaired persons, there are still a few core issues which need to be keenly addressed such as detection of hanging objects, providing hands-free environment, prevention of accidental damage to surroundings, etc. Obstacles like hanging tree branches, open windows, hanging objects or boards on the roads, are few of the hurdles which still pose a problem for the blind. Smart canes do not provide a solution to such problems, although detection of potholes and obstacles lying on the ground have successfully been achieved. Furthermore, with a huge section of the visually impaired being uneducated and financially weak, most smart devices available in the market remain unaffordable and unusable. In this paper, we propose a solution for such obstacles in the form of the “iCap”. The iCap is a light weight and low-cost embedded system; an intelligent cap capable of detecting potholes, obstacles lying on the ground as well as hanging obstacles using a pair of ultrasonic sensors (HC-SR04). It enables the wearer (the visually impaired person) to navigate independently without the fear of being hit by random obstacles. Additionally, experiments were carried out to find the actual area within which an object would be detected by the iCap, and also the thresholds of size and shape of objects beyond which the objects would remain undetected
A Review on Correlation between Marshall Stability and ITS values for Bituminous Mixes with RAP
Authors: Sakshi Er.
Published: June 2023

Abstract: Utilization of recycled materials in DBM mixes is gaining popularity due to environmental concerns and the potential for cost savings. The performance of DBM is influenced by several factors, including the choice of binder grade and the incorporation of recycled materials. However, the impact of recycled materials on the mechanical properties of the mix, as measured by Marshall stability and indirect tensile strength, needs to be thoroughly understood. Although the effect of RAP addition in DBM has been studied in relation to the Marshall test but not much is known about its effect on Indirect Tensile Strength. Marshall Stability and ITS have alone been the subject of several research investigations, but their combination has received far less attention. The correlation between Marshall Stability and ITS was researched to some extent for virgin mixes but not with recycled material. An effort has been made to examine their correlation in this study. This study aims to explore the potential benefits of incorporating RAP in DBM mixes and how it affects the correlation between the two parameters.

A Preliminary Study for Effect of High Flow Oxygen through Nasal Cannula Therapy in Carbon Monoxide Poisoning
Authors: Kim Young-Min , Kim Sang-Chul , Park Kwan-Jin , Lee Seok-Woo , Lee Ji-Han , Kim Hoon
Published: June 2023

Purpose: Acute carbon monoxide (CO) poisoning is one of the most common types of poisoning and a major health problem worldwide. Treatment options are limited to normobaric oxygen therapy, administered using a non-rebreather face mask or hyperbaric oxygen. Compared to conventional oxygen therapy, high-flow nasal cannula oxygen (HFNC) creates a positive pressure effect through high-flow rates. The purpose of this human pilot study is to determine the effects of HFNC on the rate of CO clearance from the blood, in patients with mild to moderate CO poisoning. Methods: CO-poisoned patients were administered 100% oxygen from HFNC (flow of 60 L/min). The fraction of COHb (fCOHb) was measured at 30-min intervals until it decreased to under 10%, and the half-life time of fCOHb (fCOHb t1/2) was subsequently determined. Results: At the time of ED arrival, a total of 10 patients had fCOHb levels ≥10%, with 4 patients ranging between 10% and 50%. The mean rate of fCOHb elimination patterns exhibits logarithmic growth curves that initially increase quickly with time (HFNC equation, Y=0.3388*X+11.67). The mean fCOHbt1/2 in the HFNC group was determined to be 48.5±12.4 minutes. Conclusion: In patients with mild to moderate CO poisoning, oxygen delivered via high flow nasal cannula is a safe and comfortable method to treat acute CO toxicity, and is effective in reducing the COHb half-life. Our results indicate HFNC to be a promising alternative method of delivering oxygen for CO toxicity. Validating the effectiveness of this method will require larger studies with clinical outcomes.
Discrepancies and Validation of Ethanol Level Determination with Osmolar Gap Formula in Patients with Suspected Acute Poisoning
Authors: Jung Haewon , Lee Mi Jin , Cho Jae Wan , Ahn Jae Yun , Kim Changho
Published: June 2023

Purpose: Osmolar gap (OG) has been used for decades to screen for toxic alcohol levels. However, its reliability may vary due to several reasons. We validated the estimated ethanol concentration formula for patients with suspected poisoning and who visited the emergency department. We examined discrepancies in the ethanol level and patient characteristics by applying this formula when it was used to screen for intoxication due to toxic levels of alcohol. Methods: We retrospectively reviewed 153 emergency department cases to determine the measured levels of toxic ethanol ingestion and we calculated alcohol ingestion using a formula based on serum osmolality. Those patients who were subjected to simultaneous measurements of osmolality, sodium, urea, glucose, and ethanol were included in this study. Patients with exposure to other toxic alcohols (methanol, ethylene glycol, or isopropanol) or poisons that affect osmolality were excluded. OG (the measured-calculated serum osmolality) was used to determine the calculated ethanol concentration. Results: Among the 153 included cases, 114 had normal OGs (OG≤14 mOsm/kg), and 39 cases had elevated OGs (OG>14). The mean difference between the measured and estimated (calculated ethanol using OG) ethanol concentration was -9.8 mg/dL. The 95% limits of agreement were -121.1 and 101.5 mg/dL, and the correlation coefficient R was 0.7037. For the four subgroups stratified by comorbidities and poisoning, the correlation coefficients R were 0.692, 0.588, 0.835, and 0.412, respectively, and the mean differences in measurement between the measured and calculated ethanol levels were -2.4 mg/dL, -48.8 mg/dL, 9.4 mg/dL, and -4.7 mg/dL, respectively. The equation plots had wide limits of agreement. Conclusion: We found that there were some discrepancies between OGs and the calculated ethanol concentrations. Addition of a correction factor for unmeasured osmoles to the equation of the calculated serum osmolality would help mitigate these discrepancies.

Integral Sliding Mode-Based Event-Triggered Nearly Optimal Tracking Control for Uncertain Nonlinear Systems
Authors: Zhang Yongwei , Zhang Shunchao , Wang Yonghua , Liu Dacai , Zhuang Jiawei
Published: June 2023

In this paper, an event-triggered nearly optimal tracking control method
is investigated for a class of uncertain nonlinear systems by
integrating adaptive dynamic programming (ADP) and integral sliding mode
(ISM) control. By introducing a neural network (NN) adaptive term, the
designed ISM-based discontinuous control law is employed to eliminate
the influence of the uncertainties and obtain the tracking error system
constructed from the sliding mode dynamics, as well as relax the known
upper-bounded condition of uncertainties. In order to guarantee the
stability of tracking error system and improve the control performance,
under the ADP technique, a critic NN is applied to approximate the
optimal value function for solving the event-triggered
Hamilton-Jacobi-Bellman equation and the event-triggered nearly optimal
feedback control is obtained. The feedback control law is updated and
transmitted to plant only when events occur, thus both the communication
and the computational resources can be saved. Furthermore, the stability
of tracking error is proven thanks to Lyapunov’s direct method. Finally,
we provide two simulation examples to validate the developed control
scheme.
Identification Method and Device for Single-Phase-to-Ground Fault Based on Electric Field Variation in Small-Current Grounded Distribution Systems
Authors: Li Yajie , song xiaohui
Published: June 2023

Considering the low identification accuracy of
single-phase-to-ground(SLG) fault in distribution systems with the
neural point small-current grounded, breaking through the traditional
fault identification method based on voltage or current, this paper
focuses on mining the features of electric field variation when SLG
fault occurs. Firstly, based on the charge simulation method, the
electric field at the same height under three-phase distribution lines
and that on the line surface during SLG fault are respectively
calculated. Accordingly, the variation law of electric field in
small-current grounded distribution systems during SLG fault is obtained
theoretically, and the corresponding relationship between the variation
mode of electric field and the occurrence of SLG fault is established.
Besides, MEMS sensor is innovatively adopted for electric field
measurement in distribution systems by taking advantage of its small
size, low power consumption and high accuracy, and its integration
scheme with fault indicator is formed. On this basis, a SLG fault
identification method and corresponding devices based on the variation
of electric field are proposed, and the effectiveness is verified by
experiments.

Authors: Huan Jiajia , Ding Qiaoyi , Chen Yusi
Published: June 2023

In the context of the energy crisis, the development of low-carbon
integrated energy systems has become a prominent research area. This
article addresses the challenges posed by high energy consumption and
emissions in integrated energy systems by proposing a multi-stage
planning method for low-carbon integrated energy that considers load
time transfer characteristics. The first step involves examining the
time transfer characteristics of demand response and analyzing the
economic benefits of integrated energy systems participating in the
electricity-carbon market. Subsequently, a multi-stage green low-carbon
planning model for the integrated energy system is constructed. To
validate the effectiveness of the proposed model, actual calculation
results are obtained. These results demonstrate that demand response,
specifically in data centers, can significantly reduce the operational
costs of integrated energy systems. Furthermore, the multi-stage
low-carbon planning approach is shown to be more reasonable and
economically beneficial compared to single-stage planning. Overall, this
research article provides insights into the development of low-carbon
integrated energy systems within the context of the energy crisis. By
considering load time transfer characteristics and employing a
multi-stage planning method, the article highlights the potential for
reducing costs and improving the overall efficiency of integrated energy
systems.

The Korea Aerospace Research Institute (KARI) has collaborated with Jeollanamdo Agricultural Research & Extension Services and Chonnam National University to establish a ground observation tower for evaluating the value-added products (such as surface reflectance and Normalized Difference Vegetation Index) and improving algorithms of domestic development satellites (Korea Multi-Purpose Satellite-3, 3A and 7). The ground measurement tower, installed at the Jeollanamdo Naju ground observation site (NGOS), constantly observes surface hyperspectral reflectance and atmospheric information, providing the advantage of real-time algorithm validation improvement when satellite acquires images of the site. The NGOS operates hyperspectral radiometer equipment (6 types), meteorological observation equipment (5 types), sky radiometer (1 type), and eddy flux observation equipment (2 types), along with a web service for display and data processing. The ground observation site equipment that is being installed and operated can be utilized in various fields such as carbon circle, agriculture, environment, atmosphere and climate change, in addition to validation of satellite value-added products. This study aims to introduce KARI NGOS for user data sharing and highlight the characteristics of the measured data.

Human Settlements and Ecological Footprints: As such, the ecosystems are the planet's life-support systems for the human species and all other forms of life. The ecological alterations in turn may lead to irreparable climate change, and have repercussions on human health, which are complex. The ecological alterations affect the distribution of patterns of human settlement, nutritional and health status, and disease patterns including pandemics. COVID-19 Pandemic and the Clinical Fallouts: There have been turbulent times with the novel pandemic COVID-19, engulfing, imprisoning, and debilitating the humanity all over the Globe. The unabated transmission of the virus led to immense human suffering and overwhelmed healthcare facilities. The disease has high infectivity and fatality, and the survivors have propensity to suffer with organopathies and exacerbation of other pre-existing diseases. Changing Healthcare Scenario and Options: The fallouts of COVID-19 pandemic have been striking. The pandemic has been a reality check for various provisions of available healthcare. As the existing healthcare facilities were unable to cope with the sudden surge leading to an intense pressure on the system, the pandemic has acted as a transformation catalyst and accelerated transformation in healthcare including remote and Hospitalat-Home care. Planning Healthcare for Post-Covid illness: The COVID-19 now persists as endemic in most places with the infection affecting those with a high-risk. Presently, a heightened awareness is required for diagnosing post-Covid symptoms and complications. There are needed specialized OPD services for diagnostic workup, treatment, and regular follow up, along with a dedicated indoor facility for profiling the post-Covid illness, treatment, and intensive care.

There are many different types of immune deficiency described today and many of them can increase the patient to a variety of different symptoms such as the increased chance to have cancer. In this article, I am describing a new type of immune deficiency that we cannot prove by laboratory tests because they are in the energy level and affects the energy of the five internal massive organs of the five elements theory of traditional Chinese medicine, after the implementation of the modernization of telecommunication, leading to an increased chance to have any kind of emotional or physical disease because these organs are responsible for the production of internal energy for maintenance of our survival. The use of highly diluted medications according to the theory written by myself (2020) titled Constitutional Homeopathy of the Five Elements Based on Traditional Chinese Medicine in this new type of population that we are facing nowadays is very important to keep the battery of these organs working and functioning to maintain our immune system in adequate level to prevent the development of diverse diseases, in the last phase, the formation of cancer.

Evaluation of Self-Sufficiency in seniors
Authors: Hudáková Anna
Published: June 2023

Background: Performance falls in old age and the onset of chronic diseases is developing a series of malfunctions and consequently there is impaired self-sufficiency and dependence. Methods and Sample: The aim of this work was to determine how perceived self-sufficiency and quality of life among seniors in the institutional facilities. We selected in this work a sample of 212 seniors with standardized questionnaire surveyed the relationship of self-sufficiency and quality of life of the seniors population. Based on statistical comparisons, using Mann - Whitney test. Results: We found poorer self-sufficiency in geriatric patients (ADL score, M=11,65) compared with residents in facilities for the elderly (ADL score, M=8,92). In our study confirmed a clear dependence on the level of self-sufficiency and quality of life of seniors (p < 0.001). ADL test has been identified in the region of Presov from the group of 1028 seniors 65 years and older 149 probants who completed the test insufficiently. Conclusions: Recommendations contained in the ADL tests, balance tests and others are part of a comprehensive geriatric assessment. The quality of life of seniors is an important indicator of their care
Spontaneous Neonatal Gastric Perforation: About Two Cases Treated with Success in Cotonou
Authors: Séraphin Gbenou Antoine
Published: June 2023

Neonatal gastric perforation is rare with a serious prognosis. Over a period of 10 years we had two cases successfully treated in our departments. Cases: It was a girl and a boy, vaginely delivered in the same year. The pregnancy was well followed in the first case and badly in the second. APGAR score at birth, at 2700 g girl was 10-10-10, and at 2900 g boy at 7-7-8 after resuscitation. On admission, newborns were cyanotic, tachycardic and tachypnotic; there was abdominal distension with diffuse abdominal tympanism, occurring on the second day, and scrotal swelling in addition for the boy. The abdominal X-rays objectified a massive pneumoperitoneum in the shape of a “saddle horse”. Laparotomy found gastric perforation in the area of parietal hypoplasia in both cases. An excision suture had been performed. The postoperative course was simple. Conclusion: Spontaneous neonatal gastric perforation is rare. Early diagnosis and management had resulted in a favourable outcome of the cases
Neonatal Atrial Flutter: Adenosine Dilemma
Authors: Bamurshed Emad
Published: June 2023

Background: Atrial flutter (AFl) is a rare type of neonatal tachyarrhythmia, which is recognized by saw-tooth waves on electrocardiogram (ECG), and an atrial rate of up to 500 beats/minute. The mechanism of AFl is sustained by a macro-reentrant circuit pathway which is limited to the atrial wall, however the atrioventricular (AV) node is not involved of the reentrant circuit. Case Presentation: A 2-day-old, full term, male infant was born to a hypertensive mother, by cesarean section, presented to the pediatric emergency department at Maternity and Children hospital with history of cyanosis and decrease oral intake. At the physical examination, both tachypnea (70/min) and tachycardia (218/bpm) were determined. An electrocardiogram confirmed atrial flutter with 3:1 atrioventricular conduction. AFl didn’t respond to adenosine administration, therefore, electrical cardioversion was required. After conversion to normal sinus rhythm, amiodarone and propranolol therapy were started to maintain sinus rhythm afterward. With no further incidence of AFl or other arrhythmias, the infant was discharged at 9th day of life and in good general state with propranolol therapy, and was followed in the cardiac clinic. Conclusion: Electrical cardioversion with energy of (0.5-1 J/Kg) proved to be the most effective in establishing sinus rhythm, and is safe for neonatal patients. Adenosine doesn’t treat tachycardia of atrial origin, such as AFl. However, adenosine administration may help in identifying AFl, demonstrating the arrhythmia-characteristic saw-tooth waves in the ECG.
