We conducted, for the first time, a study of the long-term evolution of an inner mouth bar in a microtidal environment that complements field observations with detailed numerical modelling of the ...same morphodynamics. Images collected by a video-monitoring station, from 2016 to 2019, were processed to study the evolution of a persistent inner mouth bar formed inside the highly engineered Misa River estuary (Senigallia, Italy) after years of reduced precipitation and discharges. We developed a semi-automatic procedure to detect the emerged area of this deposit. We seek to quantify the relationship between the long-term evolution of the bar and the forcing from the river, waves and tides. The observed high peaks in river discharge caused a strong downriver bar migration (i.e. almost twice the river width). Conversely, the observed sea storms produced an upriver bar migration smaller than one river width. A much slower and weaker (less than half the river width) upriver migration was also observed during periods of large area accretion and due to mild wave climate. Moreover, results showed that the sea water level variation did not directly impact the morphodynamics of the estuary, affecting the emerged portion of the bar only. Numerical simulations, run with Delft3D, were used to complete the information coming from field observations. After some checks on the proper use of the solver for the scenarios and environments of interest, some parametric simulations were run to highlight the role of the different forcing on the bed evolution. Simulations showed, as expected, erosion of the riverbed and significant downriver migrations (four river widths) during peaks of river discharge comparable to the 1-year return period discharges. Numerical results also showed upriver sediment transport when the wave forcing was dominant, with 10-years return period waves inducing an upriver bar migration in the order of one river width. Then, one real-life event was simulated to inspect the interaction of the various forcing and to compare their effects with the observations. Our analysis provides new insight into the complex morphodynamics in a microtidal estuary when weak river discharge is opposed by sea waves driving upriver sediment transport. A more thorough understanding of the morphodynamics is needed for future forecasting of the formation and evolution of sediment deposits inside estuarine channels that can inhibit both navigation and the flux of sediment from the river to the estuary.

The text reproduces the homily delivered by Gonzalo Zarazaga, SJ on the
occasion of the funeral mass for Fr. Juan Carlos Scannone, SJ. The author,
who recognizes himself as a student, friend, ...colleague and Jesuit companion,
leaves aside the figure of the thinker, to focus on the “most human” features,
describing an arc that goes from the “dear Cachito” with which the text begins to
the "great Teacher" with which it ends.

The advent of advanced NGS technologies have led to the generation of enormous amount of sequence data which further aid in the discovery of the various type of markers such as SSRs, SNPs, InDels, ...etc. Among all these markers, microsatellite SSR markers can be mined from the ddRADseq data as certain properties of SSR markers make them ideal markers for study. These assist researchers and breeders in diversity analysis and producing new varieties with desired traits. To extract the markers, first, the ddRADseq data is assembled into consensus sequences using STACKS program which are further assembled for mining microsatellites using QDD along with MISA tool.
Microsatellites or simple sequence repeats are motifs of 1 to 6 nucleotides in length present in both coding and non-coding regions of DNA. These are found widely distributed in the whole genome of ...prokaryotes, eukaryotes, bacteria, and viruses and are used as molecular markers in studying DNA variations, gene regulation, genetic diversity and evolutionary studies, etc. However, in vitro microsatellite identification proves to be time-consuming and expensive. Therefore, the present research has been focused on using an in-house built java pipeline to identify, analyse, design primers and find related statistics of perfect and compound microsatellites in the seven complete genome sequences of coronavirus, including the genome of coronavirus disease 2019, where the host is Homo sapiens. Based on search criteria among seven genomic sequences, it was revealed that the total number of perfect simple sequence repeats (SSRs) found to be in the range of 76 to 118 and compound SSRs from 01 to10, thus reflecting the low conversion of perfect simple sequence to compound repeats. Furthermore, the incidence of SSRs was insignificant but positively correlated with genome size (R2 = 0.45, p > 0.05), with simple sequence repeats relative abundance (R2 = 0.18, p > 0.05) and relative density (R2 = 0.23, p > 0.05). Dinucleotide repeats were the most abundant in the coding region of the genome, followed by tri, mono, and tetra. This comparative study would help us understand the evolutionary relationship, genetic diversity, and hypervariability in minimal time and cost.
The Misa River on the Italian Adriatic coast is typical of the rivers that drain the Apennine Mountain range. The focus of this study, conducted in the late summer of 2013 and mid-winter of 2014, was ...to contrast the general wintertime-summertime dynamics in the Misa River estuarine system rather than investigate specific dynamical features (e.g. offshore sediment transport, channel seiche, and flocculation mechanisms). Summertime conditions of the Misa River estuary are characterized by low freshwater discharge and net sediment deposition whereas, in the wintertime, the Misa River and estuary is characterized by high episodic freshwater discharge and net erosion and sediment export. Major observed differences between wintertime-summertime dynamics in the Misa River and estuary are a result of seasonal-scale differences in regional precipitation and forcing conditions driven largely by the duration and intensity of prevailing wind patterns that frequently change direction in summertime while keep almost constant directions for much longer periods in wintertime, thus generating major sea storms. Sediment deposition was observed in the final reach of the Misa River and estuary in the summertime. However, in the wintertime, large flood events led to sediment erosion and export in the final reach of the Misa River and estuary that, in conjunction with storm-wave-induced mud transport, led to sediment deposition at the river entrance and in the adjacent nearshore region. The seasonal cyclic pattern of erosion and deposition was confirmed with bathymetric surveys of the final reach of the estuarine region. A critical component for the balance between summertime deposition and wintertime erosion was the presence of an underlying mat of organic deposits that limited the availability of sediments for erosion in winter, when massive debris transport occurs. Further, suspended cohesive sediments flocs were subjected to smaller hydrodynamic stresses in the summertime favoring deposition within the estuary. Conversely, during wintertime storms, flocs were subjected to larger hydrodynamic stresses favoring breakup into smaller flocs and deposition outside the estuary.
•Waves-tide-river flow interaction in the final river reach is stronger in summertime.•River dominates on sea forcing in wintertime, even during low-flow conditions.•An underlying mat of organic deposits reduces the wintertime bed erosion.•During storms, waves significantly influence hydrodynamics nearby the estuary.•Complex sediment transport and erosion/deposition patterns nearby the estuary.
The Misa Criolla by Ariel Ramirez is a symbol of liberation theology in South America. Written between 1963–1964, this musical work is the result of the decisions made on the sacred liturgy at ...Vatican II and the Indigenous Movements of the 1960s and 1970s. It became popular around the world and helped bring attention to the indigenous poor of South America through its indigenization of the Roman Catholic Mass text and music directly after the Second Vatican Council. The Misa Criolla, however, can only be fully appreciated by understanding its process of localization, from its historical context, theological underpinnings to its musical attributes. From a liberationist perspective, it represents the compromise of the openness, liturgically and theologically, of Vatican II and more conservative movements afterwards through the localization of the Catholic Mass liturgy.
The emergency situation due to the Covid-19 pandemic has forced Catholics to worship by attending online mass. Although it is seen as a quick and responsive solution for the Church, many have ...questioned the efficacy or usefulness of online mass as a means and sign of God's salvation for His people. This paper provides an explanation of the efficacy of online mass as a sacrament of salvation by using the text Mark 5:25-34 about a haemorrhaging woman suffering who received miracles of healing after touching the garment of Jesus. This study was conducted by Narrative Criticism with the Exegetical Symbol Analysis approach. The analogy of the miracle of healing obtained by touching the robe of Jesus provides an understanding that the efficacy of online mass as a sacrament of salvation continues to work even though it is not experienced directly or in distance.Abstrak. Kondisi darurat akibat pandemi Covid-19 memaksa umat Katolik beribadah dengan mengikuti misa secara online. Walaupun dipandang sebagai solusi cepat dan tanggap Gereja, banyak yang mempertanyakan efikasi atau daya guna misa online sebagai sarana dan tanda keselamatan Tuhan bagi umat-Nya. Tulisan ini memberi penjelasan tentang efikasi misa online sebagai sakramen keselamatan dengan menggunakan teks Markus 5:25-34 tentang perempuan penderita pendarahan yang memeroleh mukjizat penyembuhan setelah menyentuh jubah Yesus. Metode yang digunakan adalah Kritik Naratif dengan pendekatan Eksegese Analisis Simbol. Analogi mukjizat penyembuhan yang diperoleh hanya dengan menjamah jubah Yesus memberikan pemahaman bahwa efikasi misa online sebagai sakramen keselamatan tetap bekerja walaupun tidak dialami secara langsung alias berjarak.
The focus of this Special Issue is language translation in the process of localizing religious musical practice. As an alternative to related concepts (such as contextualization and indigenization), ...musical localization is presented by ethnomusicologists Monique Ingalls, Muriel Swijghuisen Reigersberg, and Zoe Sherinian in Making Congregational Music Local in Christian Communities Worldwide (Routledge, 2018) as an effective way to account for the complex, diverse, and shifting ways in which religious communities embody what it means to be local through their musical practices: “Musical localization is the process by which Christian communities take a variety of musical practices – some considered ‘indigenous,’ some ‘foreign,’ some shared across spatial and cultural divides; some linked to past practice, some innovative – and make them locally meaningful and useful in the construction of Christian beliefs, theology, practice, and identity.” (13) This Special Issue shows the balance of translation priorities that local congregations can weigh as they work, between externally prescribed guidelines and exclusively local realities; between translations more oriented to the source language and culture, making that reality more plain, or to the recipients, ensuring that the meaning is adequately transferred to a new context; and between even the decision to translate or not, perhaps choosing to sing the songs of another culture and language as they are while risking appropriation.
