Abstract: The mualaf community of Kala Hamlet, Wih Ilang Village , Central Aceh Regency, Aceh Province, embraced Islam simultaneously and massively. They are Karo Catholics who previously lived in the Karo District of North Sumatra Province. One of the reasons for the transfer of the Karo community to the Kala hamlet was to make a living. The transfer process has been going on since the 1990. It takes process and effort to become a good Muslim. The purpose of this research is to know the religious transformation in the field of worship. This research uses descriptive qualitative with in-depth interview techniques, FGD, documentation and observation. The validity of the data uses triangulation techniques with Milles and Hubberman analysis . Based on the results of the study, it was found that the converts of the people of Kala underwent a process of transforming religious life in the field of worship by committing to perform worship according to Islamic teachings properly and correctly , despite the limited conditions and constraints when embracing Islam had been 30 years old . thus causing them to experience delays in understanding the Koran reading and prayer reading in worship rituals. In addition there are still many practices of compassion that they have not yet understood and will result in suboptimal levels of worship.

Orbital Motion, Variability, and Masses in the T Tauri Triple System
Authors: Schaefer G. H. , Beck Tracy L. , Prato L. , Simon & M. 
Published: June 2020

Abstract
We present results from adaptive optics imaging of the T Tauri triple system obtained at the Keck and Gemini Observatories in 2015−2019. We fit the orbital motion of T Tau Sb relative to Sa and model the astrometric motion of their center of mass relative to T Tau N. Using the distance measured by Gaia, we derived dynamical masses of

M
⊙ and M
Sb = 0.43 ± 0.06

. The precision in the masses is expected to improve with continued observations that map the motion through a complete orbital period; this is particularly important as the system approaches periastron passage in 2023. Based on published properties and recent evolutionary tracks, we estimate a mass of ∼2 M
⊙ for T Tau N, suggesting that T Tau N is similar in mass to T Tau Sa. Narrowband infrared photometry shows that T Tau N remained relatively constant between late 2017 and early 2019 with an average value of K = 5.54 ± 0.07 mag. Using T Tau N to calibrate relative flux measurements since 2015, we found that T Tau Sa varied dramatically between 7.0 and 8.8 mag in the K band over timescales of a few months, while T Tau Sb faded steadily from 8.5 to 11.1 mag in the K band. Over the 27 yr orbital period of the T Tau S binary, both components have shown 3–4 mag of variability in the K band, relative to T Tau N.
10 Years of Stellar Activity for GJ 1243

Published: June 2020

Abstract
The flaring M4 dwarf GJ 1243 has become a benchmark for studying stellar flare and starspot activity thanks to the exceptional photometric monitoring archive from the Kepler mission. New light curves from the Transiting Exoplanet Survey Satellite (TESS) mission for this star allow precise stellar activity characterization over more than a decade timescale. We have carried out the first flare and starspot analysis of GJ 1243 from over 50 days of data from TESS Sectors 14 and 15. Using 133 flare events detected in the 2 minute cadence TESS data, we compare the cumulative flare frequency distributions, and find the flare activity for GJ 1243 is unchanged between the Kepler and TESS epochs. Two distinct starspot groups are found in the TESS data, with the primary spot having the same rotational period and phase as seen in Kepler. The phase of the secondary spot feature is consistent with the predicted location of the secondary starspot and measurement of weak differential rotation, suggesting this secondary spot may be long-lived and stable in both latitude and longitude. As expected for this highly active star, the constant spot and flare activity reveal no sign of solar-like activity cycles over 10 yr. However, we highlight the unique ability for Kepler and TESS to use flare rates to detect activity cycles.
Physics of Magnetohydrodynamic Rossby Waves in the Sun

Published: June 2020

Abstract
Evidence of the existence of hydrodynamic and MHD Rossby waves in the Sun is accumulating rapidly. We employ an MHD Rossby wave model for the Sun in simplified Cartesian geometry, with a uniform toroidal field and no differential rotation, to analyze the role of each force that contributes to Rossby wave dynamics, and compute fluid particle trajectories followed in these waves. This analysis goes well beyond the traditional formulation of Rossby waves in terms of conservation of vorticity. Hydrodynamic Rossby waves propagate retrograde relative to the rotation of the reference frame, while MHD Rossby waves can be both prograde and retrograde. Fluid particle trajectories are either clockwise or counterclockwise spirals, depending on where in the wave pattern they are initiated, that track generally in the direction of wave propagation. Retrograde propagating MHD Rossby waves move faster than their hydrodynamic counterparts of the same wavelength, becoming Alfvén waves at very high field strengths. Prograde MHD Rossby waves, which have no hydrodynamic counterpart, move more slowly eastward than retrograde MHD Rossby waves for the same toroidal field, but with a speed that increases with toroidal field, in the high field limit again becoming Alfvén waves. The longitude and latitude structures of all these waves, as seen in their velocity streamlines and perturbation field lines as well as fluid particle trajectories, are remarkably similar for different toroidal fields, rotation, longitudinal wavelength, and direction of propagation.
Modeling Photoionized Turbulent Material in the Circumgalactic Medium. II. Effect of Turbulence within a Stratified Medium

Abstract
The circumgalactic medium (CGM) of nearby star-forming galaxies shows clear indications of O vi absorption accompanied by little to no detectable N v absorption. This unusual spectral signature, accompanied by highly nonuniform absorption from lower-ionization-state species, indicates that the CGM must be viewed as a dynamic, multiphase medium, such as occurs in the presence of turbulence. Motivated by previous isotropic turbulent simulations, we carry out chemodynamical simulations of stratified media in a Navarro–Frenk–White (NFW) gravitational potential with a total mass of 1012 M
⊙ and turbulence that decreases radially. The simulations assume a metallicity of 0.3 Z
⊙ and a redshift-zero metagalatic UV background, and they track ionizations, recombinations, and species-by-species radiative cooling using the MAIHEM package. We compare a suite of ionic column densities with the COS-Halos sample of low-redshift star-forming galaxies. Turbulence with an average one-dimensional velocity dispersion of ≈40 km s−1, corresponding to an energy injection rate of ≈4 × 1049 erg yr−1, produces a CGM that matches many of the observed ionic column densities and ratios. In this simulation, the N

ratio is suppressed from its equilibrium value due to a combination of radiative cooling and cooling from turbulent mixing. This level of turbulence is consistent with expectations from observations of better constrained, higher-mass systems and could be sustained by energy input from supernovae, gas inflows, and dynamical friction from dark matter subhalos. We also conduct a higher resolution ≈40 km s−1 run, which yields smaller-scale structures but remains in agreement with observations.
Reduced Sialylation and Bioactivity of the Antifibrotic Protein Serum Amyloid P in the Sera of Patients with Idiopathic Pulmonary Fibrosis

Published: June 2020

Abstract
Pulmonary fibrosis is a chronic and generally fatal disorder characterized by progressive formation of scar-like tissue in the lungs. Sialic acids are often found as the terminal sugar on extracellular glycoconjugates such as protein glycosylations. Sialidases, also known as neuraminidases, desialylate glycoconjugates. Serum amyloid P (SAP), a pentameric serum glycoprotein that has two sialic acids on each polypeptide, inhibits the differentiation of monocytes into fibrocytes and promotes human PBMCs to accumulate high extracellular levels of IL-10. When SAP is desialylated with sialidase, the effects of SAP on fibrocyte differentiation and IL-10 accumulation are strongly inhibited. Intriguingly, in patients with pulmonary fibrosis, there are increased levels of sialidase activity in the bronchoalveolar lavage fluid, increased levels of sialidases in the lungs, and decreased levels of SAP in the sera. To elucidate the role of SAP desialylation in idiopathic pulmonary fibrosis (IPF) pathogenesis, we purified SAP from the serum of IPF patients and healthy controls and measured the extent of sialylation and bioactivity of the purified SAP. We find that some IPF patients have abnormally high levels of the sialidase NEU3 in their sera and that the SAP in the sera of IPF patients has an abnormally high extent of desialylation and an abnormally low ability to inhibit fibrocyte differentiation and induce extracellular IL-10 accumulation by PBMC. These results suggest that SAP desialylation may play a role in IPF pathogenesis and that inhibiting NEU3 could be a potential therapeutic target for IPF.

Abstract
Helminth infections are accompanied by eosinophilia in parasitized tissues. Eosinophils are effectors of immunity to tissue helminths. We previously reported that in the context of experimental filarial nematode infection, optimum tissue eosinophil recruitment was coordinated by local macrophage populations following IL-4R–dependent in situ proliferation and alternative activation. However, in the current study, we identify that control of chronic adult filarial worm infection is evident in IL-4Rα–deficient (IL-4Rα−/−) mice, whereby the majority of infections do not achieve patency. An associated residual eosinophilia was apparent in infected IL-4Rα−/− mice. By treating IL-4Rα−/− mice serially with anti-CCR3 Ab or introducing a compound deficiency in CCR3 within IL-4Rα−/− mice, residual eosinophilia was ablated, and susceptibility to chronic adult Brugia malayi infection was established, promoting a functional role for CCR3-dependent eosinophil influx in immune control in the absence of IL-4/IL-13–dependent immune mechanisms. We investigated additional cytokine signals involved in residual eosinophilia in the absence IL-4Rα signaling and defined that IL-4Rα−/−/IL-5−/− double-knockout mice displayed significant eosinophil deficiency compared with IL-4Rα−/− mice and were susceptible to chronic fecund adult filarial infections. Contrastingly, there was no evidence that either IL-4R–dependent or IL-4R–independent/CCR3/IL-5–dependent immunity influenced B. malayi microfilarial loads in the blood. Our data demonstrate multiplicity of Th2-cytokine control of eosinophil tissue recruitment during chronic filarial infection and that IL-4R–independent/IL-5– and CCR3-dependent pathways are sufficient to control filarial adult infection via an eosinophil-dependent effector response prior to patency.
Cyclophosphamide-Induced Cancers in Pemphigus Patients –A Report of Three Cases
Authors: Saoji Vikrant Abhay 
Published: June 2020

Introduction:
Cyclophosphamide is an important steroid-sparing immunosuppressive drug that was found to be effective for the treatment of autoimmune bullous disorders such as pemphigus. However, cyclophosphamide (an alkylating drug) is a mutagenic drug and is associated with the risk of malignancies. Three cases of cancers developing due to cyclophosphamide use in pemphigus are presented.

Case Report:
A 50-year-old male patient of pemphigus vulgaris received over 50 g of cyclophosphamide over 3 years. He died of bladder cancer 9 years after stopping the treatment. A 57-year-old male patient, a known case of diabetes, received over 100 g of cyclophosphamide for over 4 years for pemphigus foliaceus diagnosed with bladder cancer 5 years after stopping treatment. A 50-year-old male received around 100 g of cyclophosphamide over 3 years for pemphigus foliaceus diagnosed with squamous cell carcinoma of oral mucosa 2 years after stopping treatment.

Conclusion:
Cyclophosphamide is a mutagenic drug and is associated with the risk of malignancy which can appear many years after stopping the treatment; hence, long-term follow-up is important.

In spite of an increase in the health service coverage of the country, studies reported that significant proportion of the Ethiopian population still relies on traditional medicine, particularly on the herbal aspect, for their healthcare. The aim of the present study was to determine the extent of the concomitant use of herbal medicines with modern antiretroviral medicines and identify the commonly used herbs among patients with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in Ethiopia. A cross-sectional study was conducted from May to June, 2017 among HIV/AIDS patients in five hospitals selected from four regions and one city Administration (Addis Ababa). A total of 768 HIV/AIDS patients were successfully interviewed and included in the analysis. Most 480 (62.5%) of them were on tenofovir-disoproxil fumarate (TDF) plus lamivudine (3TC)and efavirenz (EFV) regimen. Two hundred nineteen (28.5%) patients reported that they had used herbal medicines to treat their illness; of these 145 (66.2%) used herbal products along with modern medicine. Of those who reported to have used herbal medicine with modern medicine, 53 (40.8%) claimed that they took the herbal medicines for the treatment of HIV/AIDS, while 51(39.2%) used for treating co-morbid diseases. Only 33 (15.0%) of those who used herbal medicines along with modern drugs discussed the issue either with their physicians or pharmacists. A total of 31 plant species were reported to be used for the treatment as well as alleviation of symptoms associated with the disease. The most commonly cited herbal medicines that have been used by HIV/AIDS patients to treat their comorbid diseases were Moringa stenopetala (Baker f.) Cufod. (Moringaceae) (35.6%) followed by Ocimum lamiifolium Hochst. (Lamiaceae) (18.0%), Zheneria scabra Sond. (Cucurbitaceae) (7.2%), Allium sativum L. (Alliaceae) (5.7%), and Ruta chalapensis L. (Rutaceae) (5.7%). The study revealed that close to one-third of HIV/AIDS patients interviewed reported use of herbal medicine and almost two-thirds of them did so concomitantly with modern medicine. Only small percentage of the patients who used herbal medicines along with modern drugs disclose the use either to their treating physicians or to counselling pharmacists. Practitioners involved in antiretroviral therapy (ART) clinics, therefore, need to inquire information related to the use of herbal medicines and accordingly advise the patients.

The study was carried out to find the effect of different concentrations of Soursop (Annona muricata L) leaf extract on control of Podagrica spp. and yield of okra plant (Abelnusclus esculentus (L. Moench.), at the Teaching and Research Farm at Imo State University, Owerri. The experiment was laid out in a randomized completely block design (RCBD) with five treatment levels and four replications. The treatment levels were 0% control(T1), diluted ethanol(T2), 25%concentration(T3), 50%concentration(T4) and 75%concentration(T5) leaf extracts of Annona muricata. Application of these treatments were done weekly and data were collected on number of Podagrica spp., number of damaged leaves, number of infested plants. Results indicate that the application of 75% leaf extract effectively reduced the number of (0.5) Podagrica spp. at maturity stage which was significantly different (p<0.05) from control (9.5). Higher Yield, (248.59kg/ha), mean number of fruits (35.75) and mean fresh weight (43.732g) were significantly recorded from higher dose (75%) of leaf extract of Annona muricata. Number of damaged leaves, number of infected plants were reduced significantly by all the treatments compare to control. The result showed that Annona muricata Leaf extract possess insecticidal potential in controlling this pest hence could be use as alternative to synthetic insecticide because it is environmentally friendly and cost effective

Analysis of visibility effects on free space earth-to-satellite optical link based on measurement data in Nigeria
Authors: Falodun S.E. , Ojo J.S. , Ojo O.L. 
Published: June 2020

The effect of atmospheric variables on signals propagating from earth to space are of concern in the design and performance of wireless communications systems. Since atmospheric effects which led to atmospheric losses (attenuations, fading and scintillation) are location-dependent, climatological phenomena such as fog, snow, rain, and haze has much effect on Free Space Optical (FSO) and can cause reduction in the link availability. This paper analysed the effect of fog on FSO communication links from earth to satellite links over five selected locations (Ikeja, Akure, Enugu, Jos and Port-Harcourt) in Nigeria. One year (2012) visibility data obtained at Nigeria Meteorological Agency (NIMET) have been used to estimate the specific attenuation caused by fog on FSO communication links in the selected locations. Link margin was deduced in all the five locations. The estimated specific attenuation caused by fog was based on operating frequencies associated with a typical commercial FSO. The result shows that at 352 THz frequency, Ikeja recorded the highest value of about 38.60 dB/km for the specific attenuation due to fog on FSO link followed by Akure with value of about 30.33 dB/km. Enugu recorded the least estimated attenuation of about 14.19 dB/km . The implication of the result is that Ikeja and Akure will suffer more signal loss, while Enugu will suffer less signal loss. Result on link margin performed on FSO link also showed that Ikeja has the highest link margin of -109.79 dB, Port-Harcourt with link margin value of -91.99 dB while Jos experienced lowest link margin of about -37.48 dB.
