Abstract
Background
The hybrid emergency room (ER) system can provide resuscitation, computed tomography imaging, endovascular treatment, and emergency surgery, without moving the patient. Although several reports have demonstrated the effectiveness of hybrid ER for trauma conditions, none have demonstrated its usefulness for non-traumatic critical diseases. In this observational study, we aimed to determine the benefits of hyprid ER in the treatment of patients with non-traumatic conditions.
Methods
We retrospectively reviewed the clinical characteristics of patients with non-traumatic conditions treated in a hybrid ER from August 2017 to July 2022. Patients who underwent surgery, endoscopy, or interventional radiology (IR) in the hybrid ER were selected and pathophysiologically divided into a bleeding and non-bleeding group. The severity of illness, transfusion, and prognosis were compared among the groups using Fisher’s exact test. Multivariate logistic regression analysis was performed for confirming the relationship among prognosis, transfusion, and hemorrhagic conditions in patients who underwent endoscopy and IR.
Results
Among 726 patients with non-traumatic conditions treated in a hybrid ER system, 50 patients (6.9%) experienced cardiopulmonary arrest at or before admission to the hybrid ER, 301 (41.5%) were in shock, 126 (17.4%) received blood transfusions, 42 (5.8%) died within 24 h of admission to the hybrid ER, and 141 (19.4%) died in the hospital. Of the 726 patients, 39, 122, and 100 underwent surgery, endoscopy, and IR, respectively, in the hybrid ER. In the bleeding group, patients who underwent endoscopy and IR were more in shock and were administered significantly more blood transfusions than those who underwent surgery (endoscopy: p<0.0001 and IR: p=0.0005); however, no difference in prognosis was observed. Multivariate analysis in patients who underwent endoscopy showed a trend toward more in-hospital deaths in non-hemorrhagic conditions than in hemorrhagic conditions (odds ratio=3.833, 95% confidence interval: 0.884–16.621, p=0.073); however, no significant relationship with in-hospital death was observed for any of the adjusted variables.
Conclusion
Hybrid ER may be particularly effective for hemorrhagic conditions requiring endoscopic or IR hemostasis. The combination of diagnosis and treatment without patient transfer and appropriate transfusion strategies in a hybrid ER may improve outcomes in patients with non-traumatic diseases.
The Role of Male Facial Color as a 'Badge of Status' in Barbary macaques (Macaca sylvanus)
Authors: Satishchandran Siddharth 
Published: January 2023

Abstract
Sexual selection is driven by two main mechanisms, intrasexual selection and intersexual selection. Classically, elaborate male ornamentation is considered to function as an intersexual signal, in which females choose potential mates on the basis of their conspicuous colouration. However, some studies have shown that male sexual ornamentation may also serve as an intersexual signal of strength or dominance (as ‘badges of status’), mediating conflict between males. Among primates, such signals often comprise bright colouration on the face, scrotum, or chest. The potential function as a badge of status of the dark facial colouration seen in a number of primate species is less explored. In this study of male Barbary macaques (Macaca sylvanus) living in a semi-free ranging enclosure at Trentham Monkey Forest, I predicted that darker faced males would be higher ranked, receive higher rates of submissive behavior, and spend less time with males in close proximity, respectively. I found that male facial colour was not related to rank, rate of submissions received or patterns of proximity to conspecifics. Thus, this work does not support the hypothesis that dark facial colouration serves as an intrasexual badge of status in this species.
Mortality Rate Prediction for Patients Admitted to Intensive Care Unit Based on APACHE IV
Authors: Moridani Mohammad Karimi 
Published: January 2023

Abstract
One of the important units of the hospital is the intensive care unit, which provides specialized services to patients with acute conditions. In this paper, we introduce an instrument that can improve ICU services to patients, differentiate critical patients, optimize ICU beds, and examine the severity of their disease. To predict the mortality rate, Physiont's database for computing in cardiology challenge (CinC) was used. The survival rate of patients hospitalized in the ICU was 85.33% out of 300. Among the patients, the acute physiology and chronic health evaluation (APACHE) IV scores ranged from 18 to 90, averaging 57.43±18.6. Using the APACHE IV tool, the predicted mortality rate was 24.19%, and the observed mortality rate was 35.67%. Calculations indicated that the average score of APACHE IV for the survivors was 46.84, and for the non-survivors, it was 69.35. As a result, APACHE IV proved to be a valuable tool for nurses and doctors to predict the future conditions of patients and how they will respond to the treatment process.
Bicomponent Zno-Ag janus nanoparticles with high antitumor activity <I>in vitro</I>
Authors: Bakina O. V. , Zhou V. R. , Lerner M. I. 
Published: January 2023

Background. Nanoparticles (NPs) of zinc and silver oxide are promising antitumor agents, the use of which can enhance modern approaches to cancer treatment. Using bicomponent ZnO-Ag nanoparticles, one can increase the efficiency due to the occurrence of a synergistic antitumor effect. Among the main physicochemical properties that affect the antitumor activity of nanoparticles, one can distinguish their size and distribution of components inside the particle or their microstructure, however, these aspects are currently poorly understood.The aim of this study is the synthesis of ZnO-Ag nanoparticles using electrical explosive of wire technology and the in vitro study of the antitumor activity of NPs against breast ductal adenocarcinoma MCF-7 (ATCC HTB-22) and the HeLa cell line isolated from a cervical tumor.Material and Methods. ZnO-Ag nanoparticles were obtained by simultaneous electric explosion of zinc and silver twisted wires in a gas mixing atmosphere: argon and oxygen. The content of the components was regulated by varying the wire diameters. Physicochemical properties were studied using X-ray phase analysis, thermal desorption of nitrogen, and transmission electron microscopy. Antitumor activity in vitro was studied using the MTT test against HeLa and MCF-7 cell lines.Results. As a result of an electric explosion of twisted wires in an argon + oxygen gas mixture, ZnO-Ag NPs with different contents of components and the structure of Janus nanoparticles were obtained. The study of the physicochemical properties of nanoparticles showed that an increase in the silver content led to a decrease in the average particle size, an increase in their specific surface area, an increase in their photochemical activity and the ability to generate reactive oxygen species. The high antitumor activity of nanoparticles with a minimum silver content can be explained by a decrease in the size of silver fragments from 46 nm to 23 nm and a decrease in the average particle size from 92 nm to 54 nm. A decrease in the size of NPs and their components contributes to an increase in their solubility and, accordingly, cytotoxicity. In addition, a decrease in the size of crystallites makes it possible to increase the number and length of the ZnO-Ag interface.Conclusion. In the present study, bicomponent ZnO–Ag NPs were synthesized using the joint electric explosion of zinc and silver wires in a mixed atmosphere of argon and oxygen. A study of the physicochemical properties of nanoparticles was carried out and it was found that they all have the structure of Janus nanoparticles, an average size of 54 to 92 nm, and photochemical activity and the ability to generate ROS. Using the MTT test, the antitumor activity of NPs was confrmed using MCF-7 and HeLa cell lines. The high effciency of ZnO-Ag NPs containing 20% wt. silver indicates the possibility of using these NPs in antitumor therapy.

Enhancing the Overall Heat Transfer Coefficient through Tube
Rotation of a Heat Exchanger: An Analytical Approach
Authors: Subrahmanyam Nistala Venkata , Muthuraman Jayadeekshitha , Raj Karthik , Nallamothu Mahesh , Pal Dipankar 
Published: January 2023

Background:
Flow in an annulus between two concentric cylinders or pipes is
very often observed, ranging its applications in many streams, namely, in steam generators,
condensers, petroleum science and engineering, and various flow devices in chemical
processing industries. The objective is to prove or understand the essence of parameters
like heat transfer coefficient, mass transfer coefficient, etc., depending on such flow
regimes. One such piece of equipment found in industry is a heat exchanger, where heat
transfer occurs from one medium to another.

Objective:
The present study majorly discusses increasing the heat transfer coefficient in
the case of shell and tube heat exchangers with rotation of tubes and is restricted to a single
tube inside a shell.

Methods:
The methodology section can be broadly divided into two categories. First, the
theoretical solution (obtained under certain assumptions) of the flow between two concentric
cylinders, which includes both the rotation case and no rotation case. And second,
ANSYS Fluent simulations have been presented at a steady state for both cases. All required
conditions, dimensions of the chosen geometry, and assumptions have been clearly
mentioned before getting into the discussion or along the way. Moreover, this study is
a kind of comparative study between the conventional method of operating and rotation
of tubes inside the shell and tube heat exchangers.

Results:
The results were positive from both the ways – theoretical and ANSYS, that
there was a certain increase in the heat transfer coefficient. The overall heat transfer coefficient
increased at varying flow rates (0.25 kg/s, 0.5 kg/s, and 1 kg/s) at different speeds
of rotation (100 RPM, 200 RPM, and 300 RPM).

Conclusion:
One of the most common equipment in industries is heat exchanger. Parameters
like heat transfer coefficient can be increased by rotating tube(s) of heat exchanger.
This was presented using two approaches- analytical and simulation techniques. On varying
RPM from 0 to 300, heat transfer coefficient increased by 69.1% for 1 kg/s, 124.7%
for 0.5 kg/s, and 172.3% for 0.25 kg/s.

Published: January 2023

In this study, experimental trials will be carried out to find out the optimal recipe for processing corn oil and biodiesel oil produced by UMKM in Jember Regency (Indonesia) into biodiesel known as biosolar. Experimental conditions will be optimized to obtain partial transesterification of coconut oil and corn oil using a variety of common methoxide for the production of biosolar. Biosolar production using conventional methods has not yet produced fuel that meets modern engine standards, further research is needed to overcome this problem, including by making an advanced processing method. The following experimental parameters will be varied : liquid temperature (40-60ºC), processing time (1800 to 3600 sec.), catalyst (0.5-1,25 % of total weight.), and proportional of methanol oil mix ratio (m/o) (1:3-1:6). The maximum value parameter of biodiesel reaching 98.12% was produced by methoxide from KOH at 60 minutes of process, in 60 oC temperature and an oil – methanol mix ratio of 1:0.25. The optimal conditions for biosolar production also with biosolar fuel properties varied catalysts were tested with the standard methods of 14214EN and ASTMD6751. The results showed that optimum catalysts for biosolar production using coconut oil and corn oil are 0.8 % of total weight of either KOH and NaOH catalyst.

A robotic manipulator is one type of popular industrial robot which has a shape and movement that resemble a human arm. Robotic Manipulator mainly consists of a base, arm, gripper, and control system. This research focused on the control aspect of robot manipulators to handle 1.25 kgf load through experiment as a model of the robot with inverse kinematics. The design of the robot control uses 5 degrees of freedom using a servo motor as its actuator to achieve an accurate and stable movement on its x, y, and z coordinates using a microcontroller to calculate the inverse kinematic in real-time. The robot’s control involved the kinematic system, control diagram, microcontroller, and robot programming. From the experiment, it was found that the robot manipulator was able to grip and move an object from one coordinate to another position accurately and stable with a deviation in each axis were 2-3 mm on the X, 2 mm on the Y, and 1-3 mm on the Z. As for the movement timeframe deviation that was obtained between the programmed and measured was o seconds.
A Spatial Political-Economic Review on Urban Growth in Java under Economic Liberalization of Dutch Colonialism During the 19th Century
Authors: Setiadi Hafid , Yunus Hadi Sabari , Purwanto Bambang 
Published: January 2023

This study understands the rise and fall of cities as a result of colonial worldview and practices. Based on spatial political-economic thinking, this study examines the spatial implications of Dutch colonialism on urban growth in Java during the 19th century. The practice of colonialism at that time took place in a relatively stable regional situation. The analysis of textual data from various literature indicates that the economic liberalization of Dutch colonialism in that time was a continuation of the VOC’s mercantilism but with a stronger intention to control the factors of production. Territorial expansion to fertile areas indeed encouraged the emergence of medium-sized cities in the inland, but on the other hand, degenerated several older cities on the coast. Spatially, the ambitions and practices of colonialism had a limited implication on urban growth. The combination of territorial and capital logic triggered political liquidation which was reflected in the spatial pattern of urban growth. The identity and symbol of colonial power were attached as new elements to the cities. This process revealed a locational decision to channel economic benefits to strategic places for sustaining domination of power for the long-term.
