A Multi-Hazard Historical Catalogue for the City-Island-State of Malta (Central Mediterranean)
Authors: Main Geoff , Gauci Ritienne , Schembri John , Chester David 
Published: October 2021

Abstract
The city-island-state of Malta is traditionally viewed as a low-hazard country with the lack of a long historical catalogue of extreme events and their impacts acting as an obstacle to formulating evidence-based policies of disaster risk reduction. In this paper, we present the first multi-hazard historical catalogue for Malta which extends from the Miocene to 2019 CE. Drawing on over 3,500 documents and points of reference, including historical documentary data, official records and social media posts, we identify at least 1,526 hazard events which collectively have caused the loss of at least 661 lives. Recognising that historical materials relating to Malta are complicated by the presence of a strong temporal bias, we establish a four-point reliability indicator and apply this to each of the 1,062 recordings, with the result that some 78 % show a high degree of reliability. For an island state where there are significant gaps in the knowledge and understanding of the environmental extremes and their impacts over time, this paper addresses and fills these gaps in order to inform the development of public-facing and evidence-based policies of disaster risk reduction in Malta.

Abstract
Background: Numerous vaccines are implementation for the prevention of severe course and lethal outcome of coronavirus disease 2019 (COVID-19).Objective: This systematic review aims to summarize and integrated the findings of studies regarding cutaneous side effects of COVID-19 vaccines. Methods: This systematic review conducted by searching the scientific databases of PubMed, Scopus, Science direct, and Web of knowledge from the beginning of the COVID-19 to10/5/2021. Articles were reviewed and analyzed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist.Results: Seventeen studies were included after the screening of search results based on to the eligibility criteria. The results showed that injection site reactions and delayed large local reactions were the most common side effects arising from all vaccine types. Most cutaneous reactions occurred in middle-aged women, after the first dose of vaccine, and 1-21 days after vaccination. Most cutaneous reactions were self-limiting, need little or no therapeutic intervention, and were not regarded as a barrier to injecting a second dose.Limitations:Conclusion: In certain groups such as patients with allergies and a history of local injection reactions, pre-vaccination counseling and the use of appropriate medications may be helpful. However, more studies are needed to investigate the side effect profile of all COVID-19 vaccines.

Abstract
The face mask introduction in SARS-CoV-2 pandemic situation, one of the precautionary measure to reduce the rate of transmission of infection from person to person. There are many type of of face masks enter into our global market with various size and designs. Among those, surgical mask belongs to secure an important place and this aimed to evaluate the degrading efficiency disposable face masks (single use face masks). The present study dealt with, biodegradation of face masks which is made of polypropylene with the help of bacterial strainPesudomonasaeruginosaisolated from the plastic waste dumping sites in an around the Tiruchirappalli, India. The bacteriacould degrade PP mask via the formation of biofilm on a solid medium. To degrade the PP, the mask pieces were incubated with the culture of P. aeruginosain three different solid and liquid medium (nutrient agar, Bushnell Haas agar and mineral salt medium) for 30 days at 37ᵒC. The microbial degradation(up to 33% of weight reduction of PP films within 30 days) was proved by surface changes along with the variation in the intensity of functional groups as well as carbonyl index variations using Field-Emission Scanning Electron Microscopy (FE-SEM) and Fourier Transform Infra-Red Spectroscopy (FTIR) analysis. These results suggested that P.aeruginosa strain can prove to be a suitable candidate for polypropylene mask biodegradation without causing any impairment to our health or environment.

Published: October 2021

Abstract
Purpose: To evaluate the situation in Latin America regarding the use of simulation as surgical training in the retina.Methods: An online survey was carried out to determine the resources available in simulated retinal training in Latin America. The survey was shared via email to retina fellows and subspecialists in Latin America between November 2020 and March 2021. The relevant resources for retinal subspecialty surgical training were: biological material (pig / goat eyes); artificial eyes, and virtual reality devices. The survey was divided into five sections: (1) Identification of participants (2) Availability of resources in retinal simulation (3) Types of available resources and types of practice techniques (4) Reliability of resources according to their personal experience (5) Reasons why this type of training is implemented or not. Results: 190 participants were surveyed. The overall response rate was 61.05 %. 96 (82.8%) of the 116 responding did not have access to a retinal simulation training program. Of the 20/116 that did have access (17.2%), the most frequent resource available was biological eyes 32/116 (27.6%), followed by artificial eyes 16/116 (14.0%), and virtual reality devices 15/116 (13.0%). The reasons for lack of simulation resources was economic (77.1%), followed by the lack of a physical space (17.1 %), and interestingly some participants (5.2%) reported that it did not seem necessary to use simulation to develop new surgical skills.Conclusions: Our work highlights the lack of resources for surgical training in the retina using simulation in Latin America.
Proof of Einstein's Postulates
Authors: Golovkin Boris 
Published: October 2021

Abstract
Based on the assumption that the experiment confirms the STR, it is
shown that the magnitude of the speed of light is an extremely slowly decreasing
function of its frequency. However, at frequencies less than 1 hertz, the speed
light begins to decrease sharply, and at a frequency of 4,6∙〖10〗^(-21) с-1, the speed
of light becomes zero. Such light could serve as the Absolute Reference System,
but due to their negligible mass, they do not have any effect on the processes
taking place. This explains the postulate of Einstein's principle of relativity. The
formulas for the change in the speed and frequency of light during the transition
from one IRS to another remain unchanged, which proves Einstein's postulate of
the constancy of the speed of light in any IRS.

The cryptography techniques based on Advanced Encryption Standard (AES) and Rivest, Shamir-Adleman (RSA) algorithms. The scheme uses the extracted cryptography keys from authenticated biometric attributes. The proposed scheme provides a low computational time suitable for fast responding in the emergencies. It allows securing access for the encrypted sensitive measurements, files, and images with high data integrity and confidentiality. Furthermore, it hides the confidential sensitive information with great capacity and imperceptibility through the transmitted carrier image. The security performance analysis ensures the robustness of introducing scheme against various attacks through authentication, encryption, and information hiding techniques. It resists the serious attacks, including the man in the middle, noise, and Distributed Denial of Service (DDOS) attacks.

Authors: J Nithisha , P Jesu Jayarin 
Published: October 2021

Abstract
Security is necessary today’s fast computer world during the data communications in internet and cloud environment. The cloud security is becoming very challenging task today due to the presence of huge volume of cloud users. Even though, various cloud secured storage mechanisms are available and tried to fulfill the current requirement. However, not yet fulfill the cloud user’s requirements in terms of security while storing and sharing the data in cloud. For this purpose, this work proposes a new secured storage and communication system for providing data security while storing the data in cloud database and sharing the data between the cloud users in cloud. This system consists of three different algorithms for performing prime number generation, digital signature creation for generating keys, encryption, decryption and authorization. In this paper, we propose a new technique to find a co-prime number which is used to generate keys in key generation process and also useful for performing encryption and decryption process. Moreover, a new key generation technique is also introduced for ECC and DSA using polynomial congruence for performing key generation process securely. In addition, a new Elliptic Curve and Polynomial Congruence based Encryption / Decryption algorithms for performing data encryption and decryption in the process of data storage and communication. Finally, the user authenticity is verified by the proposed digital signature algorithm in this work. The experiments have been conducted for evaluating the proposed secured storage and communication system and proved as better than others in terms of efficiency and security level.
Detecting Impacts of Surface Development Near Weather Stations Since 1895 in the San Joaquin Valley of California
Authors: Kim Diane , Christy John R. 
Published: October 2021

Abstract
Temperature readings observed at surface weather stations have been used for detecting changes in climate due to their long period of observations. The most common temperature metrics recorded are the daily maximum (TMax) and minimum (TMin) extremes. Unfortunately, influences besides background climate variations impact these measurements such as changes in (1) instruments, (2) location, (3) time-of-observation and (4) the surrounding artifacts of human civilization (buildings, farms, streets, etc.) Quantifying (4) is difficult because the surrounding infrastructure, unique to each site, often changes slowly and variably and is thus resistant to general algorithms for adjustment. We explore a direct method of detecting this impact by comparing a single station that experienced significant development from 1895 to 2019, and especially since 1970, relative to several other stations with lesser degrees of such development (after adjustments for the (1) to (3) are applied.) The target station is Fresno, California (metro population ~15,000 in 1900 and ~1 million in 2019) situated on the eastern side of the broad, flat San Joaquin Valley in which several other stations reside. A unique component of this study is the use of pentad (5-day averages) as the test metric. Results indicate that Fresno experienced +0.4 °C decade -1 more nighttime warming (TMin) since 1970 than its neighbors – a time when population grew almost 300%. There was little difference seen in TMax trends between Fresno and non-Fresno stations since 1895 with TMax trends being near zero. A case is made for the use of TMax as the preferred climate metric relative to TMin for a variety of physical reasons. Additionally, temperatures measured at systematic times of the day (i.e. hourly) show promise as climate indicators as compared with TMax and especially TMin (and thus TAvg) due to several complicating factors involved with daily extreme measurements.

Published: October 2021

Abstract
The possibilities of applying the results of modeling the landslide stress-strain state to predict landslide hazard and make management decisions under intensive and spatial development of the territories of Asian Russia are considered. Economic and spatial development of the territories concerning reorganization or formation of economically viable components of various production chains require careful consideration of their safe and continuous operation. In this respect, great attention is paid to the studies on exogenous geological processes under the complex geomorphic conditions that can have a substantial impact on the operation of production chain links. The authors present a technique for modeling a landslide slope movement caused by anthropogenic impact. The revealed patterns in which influencing factors affect vertical displacements of landslide points created the conditions for their description at a new qualitative level. Mathematical modeling of landslide slope movement is based on the dynamic-type prediction model. This made it possible to predict the displacements of observed landslide points with sufficient accuracy. Based on a geo-cognitive safety monitoring of production chain links primarily important for the social and economic development of territories, the possibility of using the prediction models of the landslide slope stress-strain behavior as a "solver" in expert systems for forecasting landslide danger when making management decisions is shown.

Published: October 2021

Abstract
RationaleIdiopathic pulmonary fibrosis (IPF) is a chronic fibrosing interstitial pneumonia of unknown cause, no therapeutic modalities could reverse or stop its ever deteriorating course. It has been found that stimulation of lung innate immunity using bacterial lysates protected against lethal pulmonary infection, we speculate it may also protect against the development of pulmonary fibrosis.MethodsC57BL/6 mice were exposed to an aerosolized mixture of polyvalent bacterial lysates (PVBLs) or phosphate-buffered saline (PBS, as control) three times on separate day, thereafter the lungs were intratracheally infused of Bleomycin (BLM). Pulmonary morphology, Ashcroft’s scale of pulmonary fibrosis and pro-inflammatory cytokines such as interferon (IFN)-γ and interleukin (IL)-4 were evaluated 14 days later.ResultsExposures of PVBLs did not induce any discernible structural abnormalities in the lung, while the ratio of IFN-γ/IL-4 was increased (P < 0.05); BLM-induced pulmonary fibrosis was associated with an overwhelming down-regulation of IFN-γ and IL-4 (P < 0.01) ; In comparison with the controls, pre-exposures of the PVBLs protected against BLM-induced pulmonary fibrosis, that was demonstrated by a greater reduction of Ashcroft’s fibrotic score [median (95%CI): 3.94 (3.33–4.56) vs. 3.04 (2.55–3.52), P < 0.05] and a greater decrease of hydroxyproline (0.93 ± 0.16 vs. 0.64 ± 0.18, g/mg, P < 0.01) as well. Though the PBVLs pre-exposures did not restore the BLM-induced down-regulation of IL-4 and IFN-γ, the ratio of IFN-γ/IL-4 maintained greater than that in the controls (2.25 ± 0.70 vs. 0.78 ± 0.33, P < 0.01). ConclusionsBLM-induced murine pulmonary fibrosis is associated with an overwhelming down-regulation of IFN-γ and IL-4. Pre-exposures of the aerosolized PVBLs protect against the BLM-induced pulmonary fibrosis.

Authors: Çetinkaya Tuğba , Kurt Muhammed Mustafa 
Published: October 2021

Abstract
Purpose: To determine the comparison of the optical biometric measurements using optical biometry in patients with previously received COVID-19 treatment and the control group.Methods: In this cross-sectional study, the COVID-19 was diagnosed by polymerase chain reaction test, clinical signs and radiologic findings. Patients with previously received COVID-19 treatment was determined as COVID-19 group and the age and sex-matched healthy subjects were served as control group. The optical biometric measurements including corneal astigmatism, keratometry, astigmatic axis, central corneal thickness, anterior chamber depth and axial length were obtained using Nidek optical biometry (AL-Scan; Nidek Co., Ltd., Japan).Results: The measurements of keratometry(p=0,47), corneal astigmatism(p=0,42), axial length(p=0,78), anterior chamber depth(p=0,46) and central corneal thickness(p=0,43) were similar between the COVID-19 and control groups. The astigmatic axis type taken from 2.4 mm of the cornea showed statistically significant difference between two groups (p=0,01), while the measurements taken from 3 mm of the cornea were similar(p=0,15). In the subgroup analysis, axial lenght, anterior chamber depth and central corneal thickness measurements were found statistically significantly higher in the male gender of the COVID-19 group (p= 0,03; p= 0,01; p=0,03, Mann Whitney U).Conclusion: Changing in the optical biometric measurements can be seen as a result of the fact that COVID-19 is more frequent and severe in male gender and SARS-CoV-2 can attach to the cornea via ACE-2 receptors. To our knowledge, there is no study about this subject yet and conducting research with other studies on this issue will provide a better enlightenment about this subject.
