Published: October 2021

This study aims to determine the effect of shelf life of duroc boar semen which was diluted using tris-egg yolk-coconut water thinner on the value of viability, abnormality, and acidity (pH). The semen used is in the form of fresh semen from 2-year-old duroc pigs. Semen was collected by a manual method using artificial broodstock. This research was conducted in November 2020 using an experimental method according to the Completely Randomized Design (CRD) procedure with 4 treatments and 4 replications so that there were 16 experimental units. Each treatment is P0: storage of semen for 0 hours, P1: storage of semen for 24 hours, P2: storage of semen for 36 hours, P3: storage of semen for 48 hours. The results showed that the use of tris-egg yolk-coconut water diluent had a significant effect (P <0.05) on viability, abnormality, and degree of acidity (pH). The mean value of spermatozoa viability was P0: 96%, P1: 93.75%, P2: 84.5%, and treatment P3: 79.5%. The mean value of spermatozoa abnormality in treatment P0: 5.25%, P1: 6.5%, P2: 11.25%, and treatment P3: 14.75%. The average value of the degree of acidity (pH) of semen P0: 8.3 P1: 7.2; P2 7,3 and P3 treatment: 7,25. It can be concluded that the dilution of semen using tris-egg yolk and coconut water can maintain the value of viability, abnormalities of spermatozoa, and degree of acidity (pH).

Las infraestructuras de transportes: buenas prácticas en la recuperación y gestión del patrimonio territorial
Authors: Lalana Soto José Luis , Ruiz Fernández Rita , Rodríguez Lázaro Francisco Javier 
Published: October 2021

Las infraestructuras y redes de transporte proyectadas y construidas desde las décadas centrales del siglo XVIII constituyen un patrimonio histórico de enorme relevancia. Sin embargo, la protección de estas vías de comunicación es todavía, en nuestro país, muy limitada y las escasas propuestas para su recuperación se han centrado, hasta la fecha, en infraestructuras que en el momento de su rehabilitación estaban abandonadas, lo que ha permitido plantear usos alternativos que no han entrado en colisión con las exigencias derivadas de la necesidad del mantenimiento de la función para la que fueron proyectadas. Además, en ocasiones, estas intervenciones se han traducido en la pérdida de elementos sustanciales no menos relevantes que los habitualmente considerados valiosos, dificultando, en consecuencia, una adecuada transmisión de los valores intrínsecos de la propia obra de ingeniería a sus potenciales usuarios. Este escenario evidencia la necesidad de establecer criterios patrimoniales de diseño e intervención que puedan incorporarse a los proyectos de acondicionamiento y recuperación de este tipo de bienes y, especialmente, de los ferrocarriles y las carreteras. En este sentido, el artículo presenta dos proyectos internacionales de recuperación —la EN2 portuguesa en el tramo comprendido entre Almodôvar y São Brás de Alportel, y el Ocho del Šargan, en Serbia—con objeto de evaluar la posibilidad de establecer prácticas que compatibilicen, de forma integrada, la preservación y difusión patrimonial, el mantenimiento de la función transporte, y las estrategias orientadas a la activación turística y el desarrollo socioeconómico de sus corredores.

Published: October 2021

The article is devoted to methods of synthesis, the structure, and spectral characteristics of zirconium and hafnium phthalocyaninates with out-of-plane coordinated ligands. The gene­ral scheme for the synthesis of out-of-plane coordinated Zr and Hf phthalocyanines includes obtaining initial dichloride or dihydroxo complexes, which then undergo substitution reactions with -dicarbonyl compounds, hydroxybenzoic, sulfo- and aliphatic carboxylic acids, etc. In the case of polyphenols, which are bidentate ligands, one ligand is coordinated to the central atom of the macrocycle. If -dicarbonyl compounds or carboxylic acids are introduced into the reaction, two ligands are coordinated. The reactivity of the out-of-plane coordinated ligands of Zr and Hf phthalocyanines was also investigated. In all obtained out-of-plane coordinated Zr and Hf phthalocyanines, the ligands are located in the cis position relative to the plane of the phthalocyanine macrocycle. X-ray diffraction, NMR, and UV-Vis spectroscopy have proved this arrangement of ligands. According to the X-ray diffraction data of Zr and Hf dibenzoylmethanato phthalocyanines, the metal atom is out of the plane of the phthalocyanine macrocycle, which itself is not planar. The central atoms are located almost in the middle between the N4 planes of the phthalocyanine macrocycle and the O4 of the extraplanar li­gands. The UV-Vis spectra of out-of-plane coordinated Zr and Hf phthalocyanines in organic solvents have a typical appearance for most metal phthalocyanines, characterized by a B-band of absorption in the region of 335–350 nm, a Q-band at 680-690 nm, and its satellite in the region of 615–620 nm. If the extraplanar ligand is a chromophore (e.g., curcumin or condensed derivatives of dehydroacetic acid), there are additional absorption bands in UV-Vis spectra located between the B- and Q-bands. The influence of the nature of the central metal atoms, ligands and solvents on the fluorescent properties of the out-of-plane coordinated Zr and Hf phthalocyanines was also discussed.

Published: October 2021

Mono- and mixed-ligand complexes of La (III) with aliphatic β-ketoesters were synthesized in the solid state. The complexes have the general formulas LаL2OH·H2O (L=meacac, etacac, alacac) and La(meacac)2X·nCH3OH(X = NO3, CH3COO; n = 1, 2). Their composition, structure, and thermal properties were established by chemical and thermal analysis, IR spectroscopy. It is shown that β-ketoesters are coordinated to the La (III) ion bidentate-cyclically into monoligand hydroxocomp­lexes. Ligand complexes with methylacetoacetate have an oligomeric structure. They consist of cationic fragments [La(meacac)2]+ with bridged connection of the nitrate or acetate anions.
The thermal destructions of LaL2OH·H2O (L = meacac, etacac, alacac), La(meacac)2NO3· 2CH3OH and La(meacac)2(CH3COO)·CH3OH were studied for the first time in the helium dynamic atmosphere by TGA-MS in the temperature range of 25–900 °C. Depending on the ligand, dehydratation of the hydroxo-complexes takes place in the 120–180 (meacac), 120–190 (etacac) or 110–160 °C (alacac) temperature range, and the mass loss corresponds with the detachment of one water molecule. Decomposition of mixed-ligand complexes starts with the detachment of methanol in the 60–100 °C range. For La(meacac)2NO3·2CH3OH the decomposition process is attended with oxidation of methanol to carbon dioxide due to reduction of the nitrate-ion to nitrogen dioxide. Further heating to 300–400 °C leads to destruction of organic parts of the complexes attended with the release of low-molecular oxygen-containing organic compounds (aldehydes, ketones, alcohols), carbon dioxide and water. At ~500 °C all the La(III) complexes under study totally decompose, yielding the oxycarbonate La2O2CO3, which was fixed by IR spectroscopy. Under further heating to 850 °С oxycarbonate gradually decomposes to La2O3 liberating CO2.

Gelang urban village 3th hamlet is working area of Rakit 1 Health Center which has a decreased percentage of elderly visits, namely 25.75% in September and 16.5% in October. This is due to the physical condition of the elderly and the concern of the elderly when the disease is revealed. The purpose of this study was to determine the participation of elderly and factors supporting and inhibiting. Methods: research method uses a qualitative approach with purposive sampling technique. Data were collected by observation, documentation, and in-depth interviews with 7 peoples. To prove the validity of the data using triangulation techniques to 5 people. Results: form of elderly participation is social participation, existence of proposals, and the provision of voluntary cash. The percentage elderly visits showed only 10.62%. This is because of positive response from elderly, as gathering place, existence gymnastics activities, distance and friendly service. The inhibiting factors are physical condition, the busyness, fear, incomplete infrastructure, lack of family support, existence of screening, and forget about the schedule of activities. Conclusion: participation still low so efforts are needed community leaders to overcome the inhibiting factors to increase elderly visits.

Suyya’s Flood: Numerical Models of Kashmir’s Medieval Megaflood and Ancient Lake Kerewa Drainage Events

Published: October 2021

In the mid-ninth century, an earthquake triggered a landslide that blocked the narrow gorge of the Jhelum River where it exits the Kashmir Valley. The landslide impounded a lake that extended ≈100 km along the floor of the valley, implying an impounded volume of ≤21 km
3
, flooding the capital, Srinagar, and much agricultural land. An engineered breach of the landslide was contrived by a Medieval engineer resulting in the catastrophic release of flood waters. Using reasonable assumptions we calculate the probable minimum drainage time of this Medieval flood (<4 days) and maximum downstream surge velocities (≈12 m/s). These would have been sufficient to transport boulders in the bed of the Jhelum with dimensions of ≈6 m, consistent with those currently present in some reaches of the river. Given the morphology of the Jhelum gorge we consider that landslide outburst floods may have been common in Kashmir’s history. Ancient shorelines indicate that paleo-lake volumes in the Kashmir Valley may have exceeded 400 km
3
which, were they released in catastrophic floods, would have been associated with potential downstream outburst velocities >32 m/s, able to transport boulders with dimensions ≈40 m, far in excess of any found in the course of the Jhelum or in the Punjab plains. Their absence suggests that Kashmir’s ancient lakes were not lowered by outburst mechanisms much exceeding those associated with Suyya’s flood. Present-day floods have been many tens of meters shallower than those impounded by landslides in the Jhelum in the past several thousands of years. A challenge for future study will be to date Kashmir’s ancient shorelines to learn how often landslides and major impoundment events may have occurred in the valley.

Subsurface CO

storage is considered a key element of reducing anthropogenic emissions in virtually all scenarios compatible with limiting global warming to 1.5°C. The Utsira-Skade Aquifer (Utsira, Eir and Skade Formations), northern North Sea, has been identified as a suitable reservoir. Although the overall storage capacity of the full aquifer has been estimated based on regional data, it is lacking an integrated assessment of containment and internal heterogeneity, to identify optimal areas for injection and for calculation of site-specific storage capacities. A high-resolution, broadband 3D seismic reflection dataset, full waveform inverted velocity data and 102 exploration wells are utilised to provide a catalogue of CO
2
storage prospects in the northern Utsira-Skade Aquifer. This is achieved through: 1) definition of the aquifer’s spatial limits; 2) calculation of porosity distribution; 3) assessment of the extent, geomorphology, thickness variability, and containment confidence (CC) of mudstones; and 4) mapping of closures through fill-to-spill simulations. CO
2
storage capacity was calculated for the prospects using two approaches; using the full reservoir thickness (FRT) beneath the closures and using only the thickness from the closure top to the spill point (TSP), i.e., within structural traps. Porosity ranges from 29 to 39% across the aquifer and is higher in the Utsira and Eir Fms. relative to the underlying Skade Fm. The mudstone separating the Skade and Eir/Utsira Fm. has a thickness > 50 m, and is a potential barrier for CO
2
. Other intra-aquifer mudstones were mainly interpreted to act as baffles to flow. Structural traps at the top Utsira and Skade Fms. yield fifteen prospects, with criteria of > 700 m depth and FRT storage capacity of > 5 Mt CO
2
. They have a combined storage capacity of 330 Mt CO
2
(FRT) or 196 Mt CO
2
(TSP). Five prospects have a positive CC score (total capacity: 54 Mt CO
2
FRT or 39 Mt CO
2
TSP). Additional storage capacity could be achieved through more detailed analysis of the seal to upgrade the CC scores, or through use of a network of the mapped closures with a fill-to-spill approach, utilising more of the aquifer.

Published: October 2021

Developing high-quality solid-state electrolytes is important for producing next-generation safe and stable solid-state lithium-ion batteries. Herein, a three-dimensional highly porous polymer electrolyte based on poly (vinylidenefluoride-hexafluoropropylene) (PVDF-HFP) with Li6.4La3Zr1.4Ta0.6O12 (LLZTO) nanoparticle fillers (PVDF-HFP-LLZTO) is prepared using the electrospinning technique. The PVDF-HFP-LLZTO gel polymer electrolyte possesses a high ionic conductivity of 9.44 × 10–4 S cm−1 and a Li-ion transference number of 0.66, which can be ascribed that the 3D hierarchical nanostructure with abundant porosity promotes the liquid electrolyte uptake and wetting, and LLZTO nanoparticles fillers decrease the crystallinity of PVDF-HFP. Thus, the solid-state lithium battery with LiFePO4 cathode, PVDF-HFP-LLZTO electrolyte, and Li metal anode exhibits enhanced electrochemical performance with improved cycling stability.

Background: This study aimed to share the experience in applying the chimney graft technique combined with embolization for treating aortic arch rupture under emergency conditions and evaluating early-term results in these patients.Methods: This study retrospectively included patients with ruptured aortic arch lesions who received the chimney graft technique combined with embolization between March 2016 and March 2021. The primary endpoint was a technical success, deemed as successful stent graft deployment to the planned location, patency of the target branch vessel, and absence of significant type I endoleak. The secondary endpoint was clinical success defined with the size of false lumen in follow-up remaining unchanged or decreasing over time, 30-day mortality, complication, and primary patency of chimney graft.Results: This study included 12 patients (age, 61 ± 12 years; male, 83%). Five patients (42%) received single chimney, one patient (8%) received double chimney, and six patients (50%) received triple chimney. Intraoperative type I endoleak occurred in six patients (50%) who underwent endovascular embolization in the primary operation. Post-operative type I endoleak, evaluated by computed tomography angiography examination following the primary operation, occurred in seven patients (58%), including one patient who received endovascular embolization two times. All patients with post-operative type I endoleak were successfully re-treated using coil and Onyx glue within 1 week, and the median length of stay was 22 ± 11 days (range: 7–44 days). Overall technical success was 100%. Eleven patients had completed their follow-up (median, 12 months, range: 1–34 months), and one patient was out of contact. The 30-day mortality was 9% (1/11, post-operative death of a patient with cerebral hemorrhage). No major complications and no chimney compression, migration, occlusion, or stenosis were recorded during follow-up. Seven patients (58%) have ≥6 months of clinical follow-up time with appropriate imaging. In four (57%) of these patients, diameter stabilization was detected, whereas three (43%) experienced significant reduction (≥5 mm).Conclusion: The patients in this study had satisfactory early-term outcomes. The chimney graft technique combined with coil and Onyx glue embolization may be a safe and effective treatment for ruptured aortic arch lesions under emergency conditions.
