Body, Shadow and Death: Redefinition of the Origin of Painting with Tracing the Shadow
Authors: Chen Liwen
Published: July 2022

The origin of things has always captivated people; for painting, there are several myths to illustrate it. In western, Pliny the Elder contributed one of the most antiquity stories in his Natural History; from 1770 to 1820, particularly in Britain and France, there are an increasing number of works based on this story, the majority of which are composed of the same elements: classical environment, two lovers, as well as shadow. Considering Joseph Benoit Suvée's the Invention of the Art of Painting in 1791 as a starting place, this paper intends to challenge Plato's reasonable rejection of shadows while, in the process, analyzing Hans Belting's theory of image anthropology, the present essay focuses on two key concepts of the shadow with the truth. Thus, Pliny argued that shadows may be genuine, whereas Plato held that they could be dangerously deceptive.
Impact of Urbanization on Mortality in China
Authors: Wang Yu
Published: July 2022

Since the reform and opening up, the level of urbanization in China has been increasing. Urbanization has not only promoted economic growth and medical care, but also caused traffic congestion, environmental degradation, and resource depletion, and the impact of urbanization on residents' health has received increasing attention. The article analyzes the impact of urbanization on residential mortality at a national scale using panel data at the prefecture-level city level from 2010-2018, and the results show that urbanization causes a significant increase in residential mortality in China, and there are large regional differences in the impact of urbanization on mortality. Therefore, local governments should improve the level of urbanization while avoiding environmental pollution and excessive resource consumption and improving environmental quality as much as possible. At the same time, the government should improve the social security system in urban and rural areas, increase investment in infrastructure and public health services, and narrow the gap between urban and rural areas in order to improve the health of the population and reduce mortality.

Application of dark-field microscopy for detection of DNA and protein
Authors: Tang Qiuyi
Published: July 2022

Dark-field microscopy (DFM) can be used to observe living cells and microorganisms. In contrast to a bright-field microscopy, the entire field of view in DFM is dark by default and the dark background provides a high contrast. And when the researchers placed the target samples in the path of the light cone, it appeared bright because it was on an almost black background, so it shows outstanding detail. DFM is a technique to improve the contrast of specimens with poor imaging quality under conventional illumination. After the direct light is blocked by the opaque aperture in the condenser, the light passing through the sample at an inclined angle is reflected into the microscopy objective lens through diffraction, refraction and reflection, producing a bright sample image. The DFM is preferred for opaque, low transparency and low contrast specimens, especially when staining is not a viable option. DFM has the unique advantages of being easy to modify and effective, so this technology shows a diverse of different applications. Herein, this research outlines the characteristics of DFM and analyzes its application in DNA and protein detection.

Authors: Li Jiaju , Liu Jianyi , You Yunjing , Zhang Aobo
Published: July 2022

Wind energy occupies an overwhelming advantage in global renewable energy. At present, as a renewable and pollution-free natural energy, wind energy is being valued by people and is expected to become the main source of electricity in Europe, Asia, and North America in the future. A wind turbine is electric power equipment that converts wind energy into mechanical power, which drives the rotor to rotate and finally outputs alternating current. The working principle of the wind generator is that the wind wheel rotates under the action of the wind and converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates under the drive of the wind wheel shaft to generate electricity. This paper will focus on the structure of the active wind system, including the direction of wind direction detector, impeller controller, generator blade structure, location of different areas, and the prediction of wind speed by using artificial intelligence technology as well as the selection of batteries and the optimization of grid connection technology. Through the above aspects put forward a variety of ways to improve efficiency.
Application of fluorescent biosensors for heavy metal ions detection
Authors: Xu Jacob Ze Jia
Published: July 2022

Heavy metal ions can be successfully detected by using a diverse of the developed fluorescent biosensors. A major trend in designing current fluorescent biosensors incorporates nanomaterials, such as quantum dots. Combined techniques with aptamers allow for highly sensitive analyses of different heavy metal ions. Other novel methods of detection involve whole cells, for example, bacterial bioreporters. A common way of exhibiting fluorescence is through “signal-on” and “signal-off”, where some fluorescent biosensors may depend on only one state, others rely on both states of emission. The methods detecting mercury ions listed include mercury-specific oligonucleotide (MSO) probes and a dual emission ratiometric fluorescent probe using silicon (SiNPs) or gold nanoclusters (AuNCs). Methods mentioned for arsenic ions include two different kinds of fluorescent-based aptasensors and a fluorescent DNA quantum dot. As to lead ions, a fluorescent method that utilizes the interactions between DNA aptamer, acridine orange, and nanomaterials is designed. Another method is through quantum dots and DNAzyme synergetic catalytic amplification. For cadmium ions, a whole-cell bioreporter was developed that incorporated bacterial organisms. All recently published methods shared a commonality of exceptional sensitivity and selectivity.

Study on the ground mechanics index of deep soft foundation sections in the Dongting Lake region
Authors: Tian Wang
Published: July 2022

Due to its special geographical location, the Dongting Lake Plain has formed a unique Dongting Lake phase deep soft ground layer. In order to investigate its stratigraphic mechanical index, a research was carried out using pile foundation static load test and pile body stress test based on a trans-Dongting Lake high speed project. The results of the study show that the ultimate bearing capacity of the test piles in this project is greater than the ultimate bearing capacity of the piles proposed by the design, and the reasons for this deviation according to the pile stress test are mainly due to the clay layer, silty powder clay layer and the side friction resistance of the fine gravel layer at the end of the pile are significantly greater than the recommended value of the ground investigation data, while the side friction resistance of the fine sand layer, powder fine sand layer and gravel sand layer is basically the same as the recommended value of the ground investigation data, This can be used as a reference for similar projects in the future.
Reimagining Community Resilience with Health in All Policies
Authors: Morcelle Madeline
Published: July 2022

Why do some communities swiftly rise from the ashes of adversity while others do not? Resilience refers to the sustained capacity of an individual, system, or community to absorb, adapt to, and rebound from sudden shocks and chronic stressors. Shocks are the sudden adverse events that threaten major loss of life, damage to assets, and societal breakdown. Stressors are the slow-moving social, physical, economic, and ecological stressors that accumulate over time, making communities more vulnerable to shocks. A resilient community has the flexibility and resourcefulness to adapt to changing circumstances, meet community needs, and sustain conditions essential for optimal population health. Its systems are integrated and aligned to maximize efficiency and co-benefits. Mechanisms for inclusive governance engage stakeholders across government agencies, civil society, the private sector, and vulnerable populations. Policies and systems transform to reflect emerging evidence, feedback, and evolving conditions.
Thank You, Mr. Thomas Eric Duncan
Authors: Grossman Leigh
Published: July 2022

I write to extend my gratitude to Mr. Thomas E. Duncan for having personally transported the Ebola virus to the United States. In his home country of Liberia, the medical and public health infrastructure in 2014 was not equipped to contain this high-risk virus. In transporting the Ebola virus to the United States, Mr. Duncan unknowingly delivered this deadly germ to a country that has the medical, scientific, infection control, public health, and financial resources to discover how this germ is transmitted, how it is spread, develop new vaccine strategies for prevention and treatment, all ultimately leading to the possibility of worldwide eradication. When Mr. Duncan’s illness was diagnosed in Texas in 2014, and some of his caretakers became infected, the fear-based public outcry and the lack of knowledge about this virus provided the impetus to contain the few cases that occurred in the United States, but more importantly, to activate impressive research programs that describe how this virus is spread, how it is best contained, and begin to develop the prevention and treatment strategies that are required to contain this virus. In doing so, we have finally done the work for the resource-poor countries that are truly affected with large numbers of patients.

Background: Invasive fungal infections have negative impact on the health of immunocompromised individuals. With the development of fungal resistance to currently available antifungal drugs, there is a need to develop novel compounds with antifungal activity.

Aims and Objectives: The objectives of the study are as follows: (1) To synthesize novel 2-(2-pyridyl)-2H-pyrazole-3-carboxamide derivatives and (2) to evaluate the antifungal activity of novel 2-(2-pyridyl)-2H-pyrazole-3-carboxamide derivatives.

Materials and Methods: Novel 2-(2-pyridyl)-2H-pyrazole-3-carboxamide derivatives were prepared by multi step synthesis and characterized by LC-MS, 1HNMR and 13C NMR. The antifungal activity of these derivatives was assessed using Fusarium oxysporum, Aspergillus flavus, and Candida albicans by disc diffusion method.

Results: We have synthesized fourteen derivatives of 2-(2-pyridyl)-2H-pyrazole-3-carboxamide. Most of the compounds possess good antifungal activity against F. oxysporum and C. albicans strains.

Conclusion: We synthesized a series of novel 2-(2-pyridyl)-2H-pyrazole-3-carboxamide derivatives having good antifungal activity against F. oxysporus and C. albicans using a simple and low cost procedure.

Published: July 2022

Background: In pathology, students are assessed by both theory as well as practical examination, but we have more upper hand and regularity in conducting theory assessment over practical evaluation. We have put newer case-based practical examination (CBPE) module over traditional one to achieve better practical approach which consists of case scenario pertaining to hematology and urine exercise followed by its interpretation without performing procedure.

Aim and Objectives: The objective of this study were to develop and implement this new method of CBPE as a formative assessment tool for undergraduate 2nd year medical students.

Materials and Methods: We have included MBBS undergraduate students of 4th semester by dividing students into two groups. Each group consists of 25 students. Group 1 was exposed to CBPE of hematology and urine exercises, while Group 2 was exposed to conventional method of hematology and urine exercises. Evaluation form was given to each student at the end of session to know their perception and opinion regarding this newer form of practical examination.

Results: Mean marks scored in Group 1(CBPE) were 28 and in Group 2 (conventional) were 20.32 out of 40 marks. We had used unpaired t-test to calculate significance with P value which was found to be 0.0012. Feedback was based on five-point Likert scale. Most of the faculty members and students gave positive opinion for case-based pattern.

Conclusion: CBPE can be used as alternative to conventional practical examination for formative assessment with improvement in performance of students.

Background: Paravertebral block can be given for pain management after modified radical mastectomy (MRM). Although many additives to ropivacaine in PVB have been tried for post-operative analgesia, none has been found ideal.

Aims and Objectives: We have compared the duration of analgesia in PVB using adjuvant like dexmedetomidine with ropivacaine after MRM.

Materials and Methods: Sixty female patients posted for MRM and axillary dissection were split into two groups. Group R administered ultrasound-guided PVB with 20 ml ropivacaine 0.5% and Group RD administered 20 ml of 0.5% ropivacaine with dexmedetomidine 1 mcg/kg. After confirming PVB, surgery was done under general anesthesia in all patients. Time for 1st analgesia requirement was the main objective of our trial. Other objectives were to record visual analog scale scores and total analgesic need.

Results: Post-operative analgesia duration was increased in the group RD (7.11 ± 1.42 h) in contrary to Group R (3.68 ± 1.85 h). Total paracetamol consumption post-operative 24 h was decreased in Group RD (1.63 ±0.89 g) in contrary to Group R (2.74 ± 0.76 g).

Conclusion: Dexmedetomidine in PVB provides prolonged pain relief after MRM.
