Published: March 2022

En este trabajo se presenta la aplicabilidad de una herramienta computacional para diseño de concentradores solares de canal parabólico con sistema de generación directa de vapor. El diseño se aplica para la Ciudad de México, evaluando 12 valores de irradiancia solar (W⁄m^2 ), obtenidos de la estación meteorológica de la Universidad Autónoma Metropolitana, Xochimilco. El diseño del concentrador se basa en el diámetro externo del tubo absorbedor, para obtener los datos geométricos: apertura de la parábola (m), longitud focal (m), longitud total (m) y los diámetros interno y externo del tubo transparente (m). El flujo másico (kg⁄s) es el principal parámetro para obtener las características térmicas, el software muestra como resultados en forma de tablas el flujo de calor útil (W), flujo de calor perdido (W), eficiencia térmica (%) y las temperaturas de los tubos absorbedor y transparente (℃) respectivamente. El tubo absorbedor del concentrador completo, se divide en tres secciones, precalentamiento, donde el agua ingresa a la temperatura inicial (cercana o igual a la temperatura ambiente) y llega al estado de líquido saturado, en la siguiente sección se lleva a cabo la evaporación, todo el fluido de trabajo cambia de fase, desde el estado de líquido saturado hasta llegar al estado de vapor saturado, manteniendo la temperatura constante y, por último, el proceso de sobrecalentamiento, iniciando en el estado de vapor saturado, hasta llegar a la temperatura final deseada, impuesta por el usuario.

Binocular vision parameters in chronic heavy alcoholics: Short-term outcomes of alcohol detoxification
Authors: Nagaraj Kala , Kamath Vandana , Goyal Aditya 
Published: March 2022

Background: Alcohol consumption is rising in developing countries such as India, and alcohol addiction has systemic and ocular impacts. This study aimed to investigate the binocular functions of chronic heavy alcoholics before and after alcohol detoxification.
Methods: A prospective before–after study was designed and conducted at Treda De-Addiction Centre, Bengaluru, India. Males in the age range of 30–40 years who had been alcohol addicts for more than six years and met the inclusion criteria were recruited. We performed a routine optometric examination followed by detailed binocular vision assessment, including accommodative, vergence, and oculomotor tests on the first day of rehabilitation and one month after initiation of rehabilitation.
Results: Twenty-five males with of the age (mean ± standard deviation [SD]) 36.24 ± 4.33 years were evaluated. The pre- and post-detoxification mean ± SD of the monocular (right eye: 5.98 ± 3.50, 6.60 ± 3.49; left eye: 6.18 ± 3.69, 7.10 ± 3.78) and binocular accommodative facility (7.10 ± 3.93, 7.40 ± 4.51) did not change significantly (all P > 0.05). Eighteen (72%) of the participants had non-strabismic binocular vision anomalies (NSBVA), among whom the accommodative infacility and convergence insufficiency were higher in frequency and remained constant after alcohol detoxification. Furthermore, the binocular vision parameters showed no statistically significant difference between the pre- and post-detoxification values (all P > 0.05).
Conclusions: The binocular vision parameters did not change significantly after one month of alcohol detoxification in the chronic heavy drinkers. Most long-term alcoholics had NSBVA with no change after rehabilitation, indicating that short-term alcohol detoxification may not aid in the recovery of binocular parameters. However, further validation is required. Assessing the impact of vision therapy in addition to a longer period of abstinence can confirm or refute the persistence of observed effects of chronic alcohol consumption on binocular functions and NSBVA in this population.
Chitosan-coated contact lens-based ophthalmic drug delivery system to manage Acanthamoeba keratitis: a preliminary hypothesis
Authors: Sadeghi Masoud , Tajzadeh Parastoo , Zarei-Ghanavati Siamak , Arefnezhad Mohsen 
Published: March 2022

Background: Acanthamoeba species can cause devastating contact lens (CL)-related microbial keratitis. Its culture is less sensitive, and little evidence is available for the safety or efficacy profile of medications. Therefore, early diagnosis and optimal treatment remain difficult. The aim of this study was to present the hypothesis that a novel chitosan-coated CL-based ophthalmic drug delivery system has therapeutic and prophylactic effects on acanthamoeba keratitis.
Hypothesis: CL-based drug delivery is a popular sustained-release drug delivery that extends the drug release time, thus increasing its bioavailability and treatment efficacy. Chitosan, a derivative of chitin, has antioxidant and broad-spectrum antimicrobial properties against fungi, yeasts, and bacteria. It acts against microbial cells; however, whether its mechanism of action is microbiostatic or microbicidal remains unknown. It exhibits wound healing and film-forming properties. Chitosan composite films permit high transmittance of visible light, making it transparent and therefore desirable for the development of CLs. Chitosan/Ag/ZnO blend films exhibit antimicrobial activities. Further, soft CLs coated with chitosan, sodium hyaluronate, polylysine hydrobromide, and sodium alginate show drug delivery properties and reduced bacterial growth. Recently, concentration-dependent anti-amoebic activities of chitosan and nano-chitosan against the trophozoite and cystic forms of Acanthamoeba have been reported. Based on the existing evidence, we hypothesized that a chitosan-coated CL-based ophthalmic drug delivery system could have therapeutic and prophylactic effects on acanthamoeba keratitis or subsequent endophthalmitis.
Conclusions: CLs or intraocular implants with chitosan-based nanocoatings alone or in combination with routine treatment may be preventive or therapeutic for acanthamoeba keratitis or endophthalmitis. Experimental studies and further clinical trials are required to explore the efficacy and safety profile. Moreover, randomized controlled trials in healthy eyes with soft or hard CLs or orthokeratology lenses for refractive error correction may shed light on the prophylactic effect of this novel drug delivery system. Other forms of ophthalmic drug delivery systems using chitosan-based nanocoatings should be studied additionally.
Causative link between coronavirus disease vaccination and central serous chorioretinopathy: reality or illusion?
Authors: Heidary Fatemeh , Gharebaghi Reza 
Published: March 2022

Background: Most COVID-19 vaccines were authorized for emergency use. Despite a large number of vaccines that have been administered, adverse ocular effects have been reported. This paper summarized the reports about central serous chorioretinopathy (CSCR) following coronavirus disease vaccination.
Methods: In this short communication, we have included relevant publications about CSCR after coronavirus disease vaccination from the beginning of the pandemic until January 2022.
Results: The CSCR occurrence after vaccination has been reported for many years. However, a few studies are available about CSCR after coronavirus disease vaccination. Most cases revealed the development of CSCR within one week of vaccination that subsequently resolved.
Conclusions: The timeline of the CSCR diagnosis developing a few days after vaccination suggests a causative link. However, in view of the millions of administered doses of vaccines along with boosters, the causative link between CSCR and vaccines remains uncertain. Additional studies are needed to confirm a causal claim.

Published: March 2022

Abstract. The aerosol fine-mode fraction (FMF) is valuable for
discriminating natural aerosols from anthropogenic ones. However, most
current satellite-based FMF products are highly unreliable over land. Here,
we developed a new satellite-based global land daily FMF dataset (Phy-DL
FMF) by synergizing the advantages of physical and deep learning methods at
a 1∘ spatial resolution covering the period from 2001 to 2020. The
Phy-DL FMF dataset is comparable to Aerosol Robotic Network (AERONET)
measurements, based on the analysis of 361 089 data samples from 1170
AERONET sites around the world. Overall, Phy-DL FMF showed a
root-mean-square error (RMSE) of 0.136 and correlation coefficient of 0.68,
and the proportion of results that fell within the ±20 % expected
error (EE) envelopes was 79.15 %. Moreover, the out-of-site validation
from the Surface Radiation Budget (SURFRAD) observations revealed that the
RMSE of Phy-DL FMF is 0.144 (72.50 % of the results fell within the ±20 % EE). Phy-DL FMF showed superior performance over alternative deep
learning or physical approaches (such as the spectral deconvolution
algorithm presented in our previous studies), particularly for forests,
grasslands, croplands, and urban and barren land types. As a long-term
dataset, Phy-DL FMF is able to show an overall significant decreasing trend
(at a 95 % significance level) over global land areas. Based on the trend
analysis of Phy-DL FMF for different countries, the upward trend in the FMFs
was particularly strong over India and the western USA. Overall, this study
provides a new FMF dataset for global land areas that can help improve our
understanding of spatiotemporal fine-mode and coarse-mode aerosol changes. The
datasets can be downloaded from https://doi.org/10.5281/zenodo.5105617

Abstract. This paper provides initial results from a multi-model ensemble analysis based on the volc-pinatubo-full experiment performed within the Model Intercomparison Project on the climatic response to Volcanic forcing (VolMIP) as part of the sixth phase of the Coupled Model Intercomparison Project (CMIP6). The volc-pinatubo-full experiment is based on an ensemble of volcanic forcing-only climate simulations with the same volcanic aerosol dataset across the participating models (the 1991–1993 Pinatubo period from the CMIP6-GloSSAC dataset). The simulations are conducted within an idealized experimental design where initial states are sampled consistently across models from the CMIP6-piControl simulation providing unperturbed preindustrial background conditions. The multi-model ensemble includes output from an initial set of six participating Earth system models (CanESM5, GISS-E2.1-G, IPSL-CM6A-LR, MIROC-E2SL, MPI-ESM1.2-LR
and UKESM1). The results show overall good agreement between the different models on the
global and hemispheric scales concerning the surface climate responses, thus demonstrating the overall effectiveness of VolMIP's experimental design. However, small yet significant inter-model discrepancies are found in radiative fluxes, especially in the tropics, that preliminary analyses link with minor differences in forcing implementation; model physics, notably aerosol–radiation interactions; the simulation and sampling of El Niño–Southern Oscillation (ENSO); and, possibly, the simulation of
climate feedbacks operating in the tropics. We discuss the volc-pinatubo-full protocol and highlight the advantages of volcanic forcing experiments defined within a carefully designed protocol with respect to emerging modelling approaches based on large ensemble transient simulations. We identify how the VolMIP strategy could be improved in future phases of the initiative to ensure a cleaner sampling protocol with greater focus on the evolving state of ENSO in the pre-eruption period.

Authors: Abdurahman  
Published: March 2022

Masyarakat Kota Sukabumi di masa pandemi covid 19 kondisinya mengalami berbagai keterbatasan dalam beraktivitas seperti halnya; pendidikan belum bisa tatap muka, kegiatan ekonomi dibatasi waktunya, sehingga sikap masyarakat ada yang pesimis dan ada yang tetap optimis. Kondisi tersebut menstimulus terjadinya perubahan sikap dan prilaku masyarakat. Untuk menghadapi permasalahan tersebut membutuhkan penguatan sikap diri agar tangguh (sabar dan syukur), untuk itu masyarakat membutuhkan pelatihan sebagai penguatan sikap atau karakter dalam menghadapi permasalahan kehidupan yang sedang dirasakan. Metode pelatihan melalui ceramah, diskusi dan bimbingan dengan memberikan materi pada peserta pelatihan yang dilengkapi dengan pemberian modul, power point, resume materi agar peserta pelatihan memiliki input pemahaman yang baik. Hasil pelatihan menunjukkan bahwa: pelatihan character building berbasis spiritual sudah memperlihatkan adanya peningkatan namun belum optimal, (1) manajemen pelatihan pada prakteknya belum menunjukkan disiplin yang optimal pada perencanaan program, sehingga proses pembelajaran peserta pelatihan belum terbebas dari kendala teknis seperti kendala teknologi, (2) hambatan dalam proses pelatihan belum terkendali dengan optimal, selain dari masalah teknis yang berkaitan dengan teknologi juga yang berkaitan dengan minat peserta masih kurang terutama ketika memasuki sesi tanya jawab dan diskusi. (3) Potensi yang dimiliki belum bisa diberdayakan dengan optimal secara fungsional (4) Hasil pelatihan sudah menunjukkan dampak tetapi masih banyak yang harus diperbaiki terutama dalam pengelolaan proses pelatihan dan penanganan minat peserta yang masih harus ditingkatkan.
