Published: January 2023

Participation in recreation and physical activity is crucially important for better health and quality of life. No study, as per our knowledge, has explored information on health status and recreational preference in widows in Pakistan yet. Identification of these facts may help health professionals and recreational planners to plan and execute adequate interventions that may modify recreational behaviors to foster effective participation in active recreation. This may further contribute to the better health and well-being of widows in Pakistan. One hundred and forty widows voluntarily participated that were recruited from 10 union councils of Bahawalpur City of Southern Punjab region, Pakistan. The participant completed a questionnaire during a face-to-face interview with investigators. The analysis yielded that the health status of widows in this region was worse to some extent. Diseases including depression, backache, headache, blood pressure, and pain in the legs were found among our sample, although at a moderate level. It was found that keep staying at home, followed by engagement in religious activities and sleeping were the most important preferential use of leisure time. Moreover, the expensiveness of facilities for physical activities followed by lack of physical activity places and lack of parks for women found to be the predominant barriers in participation in leisure-time physical activities. The study concluded that perceptions regarding barriers to leisure-time physical activity might contribute to inactive recreational preferences that further contributed to worse health outcomes in widows.

Published: January 2023

A soccer match makes heavy demands on both aerobic and anaerobic metabolism. Elite players run 8–12 km during a game. Nevertheless, anaerobic metabolism is also crucial in sprints, jumps, and tackles. Many studies have stated that aerobic and anaerobic strength are significant features in soccer games. During a soccer match, soccer team members performed 60 to 70 runs from 12 to 15 m. Sprint running success, with or without the ball, is therefore a significant factor that can explain a winning team's supremacy. In essential ball duals, sprint could be key. In certain cases, the player should be quicker and more effective than the opponent to score goals or to avoid goals being scored. In addition, acceleration and speed can enhance skills vital to soccer, such as turning, sprinting, and changing tempo, by improving strength in appropriate muscles or muscle groups. The study was to evaluate the effect of isometric squat exercise on sprint performance of football players. The sample of 60 student were selected from the population of University of Lahore football team. Within 3 to 5 days after base training pre-test will be conducted in the morning by using 40-yard dash test. Post-test will be conducted after completion of Isometric Squat exercise training sessions. The results show that, differences between the two test 40 Yard Dash Test Post-Test of Experimental Group and 40 Yard Dash Test Post-Test of Control Group. This research study discovered that there was a statistically significant improvement in sprint performance by using Isometric Squat exercise Program.

Abstract. The unprecedented lockdown of human activities during the COVID-19 pandemic have significantly influenced the social life in China. However, understanding of the impact of this unique event on the emissions of different species is still insufficient, prohibiting the proper assessment of the environmental impacts of COVID-19 restrictions. Here we developed a multi-air pollutant inversion system to simultaneously estimate the emissions of NOx, SO2, CO, PM2.5 and PM10 in China during COVID-19 restrictions with high temporal (daily) and horizontal (15 km) resolutions. Subsequently, contributions of emission changes versus meteorology variations during COVID-19 lockdown were separated and quantified. The results demonstrated that the inversion system effectively reproduced the actual emission variations of multi-air pollutants in China during different periods of COVID-19 lockdown, which indicate that the lockdown is largely a nationwide road traffic control measurement with NOx emissions decreased substantially by ~40 %. However, emissions of other air pollutants were found only decreased by ~10 %, both because power generation and heavy industrial processes were not halted during lockdown, and residential activities may actually have increased due to the stay-at-home orders. Consequently, although obvious reductions of PM2.5 concentrations occurred over North China Plain (NCP) during lockdown period, the emission change only accounted for 8.6 % of PM2.5 reductions, and even led to substantial increases of O3. The meteorological variation instead dominated the changes in PM2.5 concentrations over NCP, which contributed 90 % of the PM2.5 reductions over most parts of NCP region. Meanwhile, our results also suggest that the local stagnant meteorological conditions together with inefficient reductions in PM2.5 emissions were the main drivers of the unexpected COVID-19 haze in Beijing. These results highlighted that traffic control as a separate pollution control measure has limited effects on the coordinated control of O3 and PM2.5 concentrations under current complex air pollution conditions in China. More comprehensive and balanced regulations for multiple precursors from different sectors are required to address O3 and PM2.5 pollution in China.
Limits and CO2equilibration of near-coast alkalinity enhancement
Authors: He Jing , Tyka Michael D.
Published: January 2023

Abstract. Ocean alkalinity enhancement (OAE) has recently gained attention as a potential method for carbon dioxide removal (CDR) at gigatonne (Gt) scale, with near-coast OAE operations being economically favorable due to proximity to mineral and energy sources. In this paper we study critical questions which determine the scale and viability of OAE. Which coastal locations are able to sustain a large flux of alkalinity at minimal pH and ΩArag (aragonite saturation) changes? What is the interference distance between adjacent OAE projects? How much CO2 is absorbed per unit of alkalinity added? How quickly does the induced CO2 deficiency equilibrate with the atmosphere? Choosing relatively conservative constraints on ΔpH or ΔOmega, we examine the limits of OAE using the ECCO LLC270 (0.3∘) global circulation model. We find that the sustainable OAE rate varies over 1–2 orders of magnitude between different coasts and exhibits complex patterns and non-local dependencies which vary from region to region. In general, OAE in areas of strong coastal currents enables the largest fluxes and depending on the direction of these currents, neighboring OAE sites can exhibit dependencies as far as 400 km or more. At these steady state fluxes most regional stretches of coastline are able to accommodate on the order of 10s to 100s of megatonnes of negative emissions within 300 km of the coast. We conclude that near-coastal OAE has the potential to scale globally to several Gt CO2 yr−1 of drawdown with conservative pH constraints, if the effort is spread over the majority of available coastlines. Depending on the location, we find a diverse set of equilibration kinetics, determined by the interplay of gas exchange and surface residence time. Most locations reach an uptake efficiency plateau of 0.6–0.8 mol CO2 per mol of alkalinity after 3–4 years, after which there is only slow additional CO2 uptake. Regions of significant downwelling (e.g., around Iceland) should be avoided by OAE deployments, as in such locations up to half of the CDR potential of OAE can be lost to bottom waters. The most ideal locations, reaching a molar uptake ratio of around 0.8, include North Madagascar, California, Brazil, Peru and locations close to the Southern Ocean such as Tasmania, Kerguelen and Patagonia, where the gas exchange appears to occur faster than the surface residence time. However, some locations (e.g., Hawaii) take significantly longer to equilibrate (up to 8–10 years) but can still eventually achieve high uptake ratios.
Ideas and perspectives: The benthic iron flux from sandy advective bioturbated sediments
Authors: Wehrmann Laura M. , Swenson Perger Darci A. , Dwyer Ian P. , Volkenborn Nils , Heilbrun Christina , Aller Robert C.
Published: January 2023

Abstract. Multiple investigators have suggested that the benthic flux of dissolved iron (Fed) from continental shelf sediments represents an important source of this micronutrient to ocean waters. The magnitude, biogeochemical controls, and seasonal dynamics of Fed fluxes to date, however, have mostly been studied for muddy cohesive sediments dominated by molecular diffusion. Data from these studies have been included in global biogeochemical models to determine the contribution of this Fe source to the ocean. Fed fluxes from sandy advective sediments have received little consideration, although these sediments cover 50–60 % of the continental shelves. Sandy permeable deposits function as dynamic catalytic filters characterized by the rapid exchange of solutes and infiltration of particles —including labile Corg and reactive metal oxides— and high biogeochemical reaction rates. In this article, we discuss how the fundamentally different modes of solute and particle transport in sands affect the sedimentary Fe cycle and Fed flux. We present a case study in which we simulate bioirrigation in sands in summer and winter. In our experiments, Fed fluxes from non-irrigated sediments under diffusive conditions did not exceed 6 and 13 μmol Fe m-2 d-1 in winter and summer, respectively. Fluxes from irrigated cores reached values of 150 μmol Fe m-2 d-1 (winter) and 115 μmol Fe m-2 d-1 (summer). The results indicate that the pumping activity of the benthic macrofauna plays a key role in controlling the extent of the benthic Fed flux from permeable sediments, and that both biogenic and physical advection enhance fluxes. We argue that bioturbated sandy advective sediments constitute an important benthic Fe source to coastal waters and advocate for a more differentiated treatment of sediment type (muddy diffusive vs. sandy advective) and macrofaunal activity -reflecting different functional groups of the macrobenthos- in global biogeochemical Fe models. A better understanding of the benthic Fe cycle in sandy advective sediments is particularly important to help predict how anthropogenic effects such as changes in the deposition patterns of Corg and metals, the expansion of oxygen minimum zones, and changes in benthic biodiversity will affect the tightly coupled benthic-pelagic ecosystem along continental shelves.
Viticulture extension in response to global climate change drivers – lessons from the past and future projections
Authors: Guiot Joel , Bernigaud Nicolas , Bondeau Alberte , Bouby Laurent , Cramer Wolfgang
Published: January 2023

Abstract. The potential areal extent of agricultural crops is sensitive to climate change and its underlying drivers. To distinguish between the drivers of past variations in the Mediterranean viticulture extension since Early Antiquity and improve projections for the future, we propose an original attribution method based on an emulation of coupled climate and ecosystem models. The emulator connects the potential productivity of grapevines to global climate drivers, notably orbital parameters, solar and volcanic activities, demography and greenhouse gas concentrations. We found that variations in potential area for viticulture during the last three millennia in the Mediterranean Basin were mainly due to volcanic activity, while the effect of solar activity and orbital changes were negligible. In the future, as expected, the dominating factor is the increase in greenhouse gases, causing significantly drier conditions and thus major difficulties for viticulture in Spain and North Africa. These constraints will concern significant areas of the Southern Mediterranean Basin when global warming exceeds +2 °C above pre-industrial conditions. Our experiments showed that even an intense volcanic activity comparable to that of the Samalas – sometimes considered as the starting point of the Little Ice Age at the mid 13th century - would not slow down this decline in viticulture extension in the southern margin of the Mediterranean area.
The World Atlas of Last Interglacial Shorelines (version 1.0)
Authors: Rovere Alessio , Ryan Deirdre D. , Vacchi Matteo , Dutton Andrea , Simms Alexander R. , Murray-Wallace Colin V.
Published: January 2023

Abstract. This paper presents version 1.0 of the World Atlas of
Last Interglacial Shorelines (WALIS), a global database of sea-level proxies
and samples dated to marine isotope stage 5 (∼ 80 to 130 ka).
The database includes a series of datasets compiled in the framework of a
special issue published in this journal (https://essd.copernicus.org/articles/special_issue1055.html, last access: 15 December 2022). This paper collates the individual contributions (archived
in a Zenodo community at https://zenodo.org/communities/walis_database/, last access: 15 December 2022) into an
open-access, standalone database (Rovere et al., 2022,
https://doi.org/10.5281/zenodo.7348242). The release of WALIS 1.0 includes
complete documentation and scripts to download, analyze, and visualize the
data (https://alerovere.github.io/WALIS/, last access: 15 December 2022). The database
contains 4545 sea-level proxies (e.g., marine terraces or fossil beach
deposits), 4110 dated samples (e.g., corals dated with U-series), and 280
other time constraints (e.g., biostratigraphic constraints or tephra
layers) interconnected with several tables containing accessory data and
metadata. By creating a centralized database of sea-level proxy data for the
Last Interglacial, the WALIS database will be a valuable resource to the
broader paleoclimate community to facilitate data–model integration and
intercomparisons, assessments of sea-level reconstructions between different
studies and different regions, as well as comparisons between past sea-level
history and other paleoclimate proxy data.
ClinoformNet-1.0: stratigraphic forward modeling and deep learning for seismic clinoform delineation
Authors: Gao Hui , Wu Xinming , Zhang Jinyu , Sun Xiaoming , Bi Zhengfa
Published: January 2023

Abstract. Deep learning has been widely used for various kinds of data mining tasks but not much for seismic stratigraphic interpretation due to the lack of labeled training datasets. We present a workﬂow to automatically generate numerous synthetic training datasets and take the seismic clinoform delineation as an example to demonstrate the effectiveness of using the synthetic datasets for training. In this workﬂow, we ﬁrst perform stochastic stratigraphic forward modeling to generate numerous stratigraphic models of clinoform layers and corresponding porosity properties by randomly but properly choosing initial topographies, sea level curves, and thermal subsidence curves. We then convert the simulated stratigraphic models into impedance models by using the velocity-porosity relationship. We further simulate synthetic seismic data by convolving reﬂectivity models (converted from impedance models) with Ricker wavelets (with various peak frequencies) and adding real noise extracted from ﬁeld seismic data. In this way, we automatically generate a total of 3000 diverse synthetic seismic data and the corresponding stratigraphic labels such as relative geologic time models and facies of clinoforms, which are all made publicly available. We use these synthetic datasets to train a modiﬁed encoder-decoder deep neural network for clinoform delineation in seismic data. Within the network, we apply a preconditioning process of structure-oriented smoothing to the feature maps of the decoder neural layers, which is helpful to avoid generating holes or outliers in the ﬁnal output of clinoform delineation. Multiple 2D and 3D synthetic and ﬁeld examples demonstrate that the network, trained with only synthetic datasets, works well to delineate clinoforms in seismic data with high accuracy and efﬁciency. Our workﬂow can be easily extended for other seismic stratigraphic interpretation tasks such as sequence boundary identiﬁcation, synchronous horizon extraction, shoreline trajectory identiﬁcation and so on.

Kakao merupakan salah satu komoditas yang memegang peranan cukup penting di Indonesia saat ini, salah satunya sebagai sumber devisa negara. Salah satu proses yang sangat berperan penting pada kualitas biji kakao yang dihasilkan adalah proses fermentasi. Fermentasi merupakan tahapan pengolahan yang sangat vital untuk menghasilkan cita rasa cokelat yang baik. Fermentasi juga berperan dalam perkembangan aroma dan rasa serta pengurangan rasa sepat dan pahit. Tujuan dari penelitian ini adalah untuk mengetahui sifat kimia pada biji kakao dengan melakukan pengujian total kadar gula, total kandungan asam, dan pH. Metode penelitian ini menggunakan perhitungan rata-rata dengan dua faktor perlakuan yaitu, faktor pertama adalah lama fermentasi yang berbeda dan faktor kedua adalah penambahan ragi roti instan yang berbeda. Hasil dari penelitian yang dilakukan menunjukkan kandungan total kadar gula yang tertinggi  yaitu 3,67% pada perlakuan dengan lama fermentasi selama 3 hari dan penambahan ragi roti instan sebanyak 0% (W0R0), total kandungan asam yang tertinggi yaitu 1,45% pada perlakuan dengan lama fermentasi selama 6 hari dan penambahan ragi roti instan sebanyak 0,5% (W1R1), dan pH yang tertinggi yaitu 4,75 pada perlakuan dengan lama fermentasi selama 3 hari dengan penambahan ragi roti instan sebanyak 0,5% (W0R1).
Patrocinia of the Arch-deaconry of Wrocław according to visitation protocols from the years 1579-1580
Authors: Wróblewski Stanisław
Published: January 2023

This article is devoted to the problematics of patrocinia of churches in the archdeaconry of Wrocław known thanks to canonical visitations from 1579-1580, carried out in accordance with the ordinances of the Council of Trent in 1547 by the archdeacon of Wrocław, Teodor Lindanus. Before proceeding with the execution of the ordinance and the visitation of the diocese, an instruction was prepared, where very strong emphasis was placed on the issue of the invocation that a given object of Catholic religious worship had. This was of great importance in the face of the development of the Reformation and the rejection of the existing sacred rite, including the cult of saints. Hence, examining the origin and meaning of church invocations, one could see the features characteristic of the religiousness of the faithful of the Church in Silesia, having their roots in the Middle Ages. Among the 36 objects visited, as many as 46 different invocations were listed, which, combined into various dedicatory variants, indicated 153 examples of saints, divine mysteries and truths of faith.The analysis of individual invocations, and searches in earlier sources, allowed to indicate the continuity of the cult, as well as its evolution emphasised by the appear-ance of other titles for the same objects. Data on patrocinia in 26 cases is the first information about the invocation for the individual churches mentioned. On the basis of the research carried out, it can be assumed that the archdeacon of Wrocław was characterised by an openness to many trends, and manifestations of the religious culture of Europe and the Church at the time.
The Pomeranian Family Circle of Fr. Józef Tocki (1805-1862), Parish Priest of Zduńska Wola. A Contribution to the Prosopographical Study of the Priests of Kujawsko-Kaliska Diocese
Authors: Szkutnik Piotr
Published: January 2023

Determining the origins of a priest is an integral part of biographical and more broadly prosopographical research on the clergy, hence it is important to demonstrate the degree of reliability of the sources that are used in such research. The descent of Józef Tocki, a Catholic priest who worked in the town of Zduńska Wola near Łódź, Poland, in the years 1834-1862, was verified in the article. He was born in 1805 in Gdańsk Pomerania in the seaside village of Kolibki. He was the son of a teacher. The noble origin declared in the priest’s biography, however, was not reflected in the parish registers, describing his relatives as “honest”. Of his seven sisters, four lived to adulthood, two of whom married teachers, and the eldest married a nobleman. The border between partitions limited contacts of the family members. Having achieved professional stability as a parish priest, Józef Tocki had an influence on the fortunes of his younger sister, who became his housekeeper. Other sisters’ marriages maintained and probably raised the family’s position in terms of connections and wealth. Their brother’s priestly duties also affected the social advancement of the schoolteacher’s children.

This body was the main organ responsible for the implementation of the resolutions of the Second Vatican Council, and the implementation of its reception in the Catholic Church in Poland. In the analysed period it was presided over by Archbishop Antoni Baraniak. The Commission was given particular attention by the Chairman of the Polish Episcopal Conference, Card. Stefan Wyszyński. Bolesław Kominek, Karol Wojtyła and Michał Klepacz made a significant contribution to the works of the Commission. Through the conciliar activity of its members, the Commission participated in the preparation of some documents, including the Pastoral Constitution on the Modern World Gaudium et spes.
Papal diplomacy in the face of the dispute for the throne of Poland in the years 1704 1709
Authors: Kopiec Jan
Published: January 2023

The following article focuses on an opinion of papal diplomacy on Stanisław Leszczyński, a rival of Augustus II, at the dispute for the throne of Poland at the beginning of the 18th century. Polish society was then divided into two political camps, which caused chaos in the country. Since the reign of Stanisław Leszczyński was considered illegal, papal diplomacy recognised absent Augustus II as the king of Poland and maintained official relationship with the Sandomierz Confederation, yet contacts with the Leszczyński’s camp were not broken off.During the preparations for the war with Sweden, Tsar Peter the Great intervened in the dispute for the Polish throne. He searched for a new candidate for the Polish crown, who could perform a similar role to that of Leszczyński towards the Swedish king. Therefore, papal diplomacy expended enormous efforts to prevent the third elections, which, as estimated by Nuncio J. Piazzo, could pose a great threat to the state. In the absence of Augustus II and a threat of the third election, papal diplomacy sought to recognise Leszczyński as the king in the first months of 1707. However, already in the summer of the same year interregnum was announced by the Sandomierz Confederation and a treaty between Charles XII and emperor Joseph I ratified in Altranstädt, which, among other things, concerned concessions for the protesters in Silesia. In consequence, papal diplomacy withdrew its support for Leszczyński and again recognised Augustus II as the king, who returned to Warsaw in 1709.
Epitaphium Ministri Generales Totius Ordinis Minorum S.P.N. Francisci From the Manuscript of the Former Bernardine Library in Karczówka (today the Diocesan Archives in Kielce)
Authors: Kardyś Piotr , Janakowski Marcin
Published: January 2023

The Diocesan Archives in Kielce keeps a manuscript unknown to a wider circle of researchers, entitled “Mortuologium seu Calendarium ...” by Timotheo Kaffka. It probably found its way into the collection of the said archives following the cassation of the Bernardine monastery at Karczówka in 1864. The manuscript, inconspicuous in appearance, contains information on the history of the Friars Minor, both the older branch – the Conventual Franciscans, the Observants (the Reformati) and the Bernardines. Mortuologium, as a work of commemorative nature, constitutes a universal type of written source, typical of the monastic Latin culture. Franciscan calendars are no exemption to this rule. Therefore, the following publication supplemented with the source appendix in the form of the list of generals OFM unpublished so far, may become both an important contribution to the existing literature on the subject and continuation of the research into the writing culture of the Polish Bernardines.

Published: January 2023

The government’s aim to accomplish social and economic development is realized through the optimal use of infrastructure. In this context, an infrastructure index is developed to investigate the role of infrastructure quality in Pakistan's economic growth from 1975 to 2018 particularly. The ARDL bounds testing cointegration with structural breaks confirm the presence of a long-run relationship amid the variables; economic growth, labour force, physical capital, and quality of infrastructure. Long-run findings indicate a positive and significant relationship between infrastructure quality and economic growth in Pakistan. From a policy standpoint, this analysis recommends that improvements in the existing infrastructure stock and utilizing the available resources efficiently would be extremely beneficial for Pakistan’s economy.
