Death as a Prerequisite for Vacating the Office of President of the Republic of Poland

This article is devoted to the issue of death as a premise for vacating the office of President of the Republic of Poland. The Constitution of the Republic of Poland comprehensively regulates the institution of substitution of the President of the Republic of Poland, specifying the legal forms of its execution and indicating the Marshals (of the Sejm and the Senate) as entities authorized to carry out the duties of the head of state. In the event of the occurrence of the death of the President, doubts arise as to the possibility of implementing civilian regulations at the time of triggering the procedure of substitution of the President provided for in Art. 131 of the Constitution. The analysis carried out in the article is aimed at answering the question of whether the Marshal of the Sejm (on whom the duty to assume the duties of head of state is incumbent), functioning in the field of constitutional law, is bound by the regulations applicable in principle on civil law grounds.

Urethral reconstruction using amniotic membrane allograft in hereditary androgen insensitivity syndrome: a case series

Abstract Partial androgen insensitivity syndrome is a rare X-linked disorder. While most cases are sporadic, familial cases are less frequent. The management of this syndrome follows a multidisciplinary approach involving hormone substitution, psychological counseling, and surgical procedures. We present a case series of three young siblings with familial partial androgen insensitivity syndrome who presented with a female phenotype. All of them were managed with hormonal treatment for 6 months followed by surgical reconstruction. The operative procedure involved phalloplasty and urethroplasty using amniotic membrane transplant, which is considered a novel technique in this group of patients. No intraoperative or postoperative complications were observed and good results were achieved within 2 years of follow-up.

About the Erdős-Hajnal conjecture for seven-vertex tournaments

A celebrated unresolved conjecture of Erdős and Hajnal states that for every undirected graph H there exists ϵ(H)>0 such that every undirected graph on n vertices that does not contain H as an induced subgraph contains a clique or a stable set of size at least nϵ(H). The conjecture has a directed equivalent version stating that for every tournament H there exists ϵ(H)>0 such that every H-free n-vertex tournament T contains a transitive subtournament of order at least nϵ(H). Both the directed and the undirected versions of the conjecture are known to be true for small graphs (tournaments). So far the conjecture was proved only for some specific families of prime tournaments, tournaments constructed according to the so-called substitution procedure allowing to build bigger graphs, and for all five-vertex tournaments. The conjecture was proved for all six-vertex tournament, with one exception, but the question about the correctness of the conjecture for all seven-vertex tournaments remained open. In this paper we prove the correctness of the conjecture for several seven-vertex tournaments.

Digestible and Metabolizable Energy in Ground Yellow Corn, Rice Bran, and Copra Meal Fed to 10 to 15 kg Philippine Native Pigs (Benguet Strain)

The experiment was conducted to determine the digestible energy (DE), metabolizable energy (ME), and apparent total tract digestibility (ATTD) of gross energy in ground yellow corn, rice bran, and copra meal when fed to Philippine native pigs. Nine barrows with an average initial bodyweight of 10 kg and ages ranging from 60 to 75 d old were housed individually in metabolism crates and randomly allotted to a triplicated incomplete 3 × 2 Latin square design with three diets and two periods. A corn-based diet containing 94.89% yellow corn and two diets containing 66.42% yellow corn and 30% rice bran or copra meal were fed to the native pigs for 10 d, which included a 5 d adaptation period and a 5 d collection period. The DE and ME in rice bran and copra meal were calculated using the substitution procedure with yellow corn as the basal ingredient. On a dry matter basis, ground yellow corn contained 3445 DE and 3314 ME kcal/kg, with 75.45% ATTD of gross energy (GE). Rice bran had 4137 DE and 4034 ME kcal/kg with 87.02% ATTD of GE, whereas copra meal contained 2914 DE and 2841 ME kcal/kg, with 64.72% ATTD of GE. These values are important in the establishment of feeding standards for the Philippine native pigs.

A Lightweight Cryptographic Algorithm Based on DNA Computing for IoT Devices

Internet of Things (IoT) applications are used in almost every part of our life, so it is important to protect the sensitive data and information that is transmitted over wireless networks such as images and documents. The IoT devices have limited computational resources; they are called limited devices due to their limited processors and memory size. Traditional encryption methods require a lot of computing power; therefore, it is difficult to implement traditional cryptographic algorithm on IoT processor. Finally, a new, lightweight encryption method based on the DNA sequence is proposed to suit the IoT devices in a way to make an easy and secure the communications among the IoT devices. DNA sequences are very random, so we have used it to make a strong secret key that is hard for attackers to break. The proposed method has an advantage in terms of efficiency and strength. Experiments and security tests show that the proposed encryption system not only has a good encryption effect and can withstand known attacks, but it is also fast enough for real-world use. The DNA key is used to encrypt files using two simple and reliable methods such as substitution and transposition procedures that meet IoT computational requirements. In addition, when compared with other encryption algorithms, the experimental results shows that the key size, encryption time, and distortion preparation are all superior.

Possibilising food translation in children’s literature

Abstract Food is omnipresent in children’s literature, from Popeye’s Spinach to Detective Cluj’s Carpenter Gums, thus signifying its immense cultural value since cultures and societies are built upon food (Keeling and Pollard 2009, 6). Food narratives are capable of performing a number of functions ranging from evoking a sense of coziness and comfort to being a cause of temptation and power struggle, and these functions ought to come under the spotlight when translating children’s books. This article focuses on the English-Greek examination of translation patterns in the Captain Underpants series and on the critical discussion of the translation strategies that have been employed for the transferring of food items to Greek children. To this end, thirty-five examples of food references are analyzed using a purpose-built schema of translation procedures. The results indicate that translators make a conscious attempt to bring foreign dishes closer to the target language culture by adopting a variety of modification and substitution procedures. This study highlights the intrinsic role that the translation tendencies of preservation, modification, substitution, expansion, transcreation, omission, and creation play in enabling food translation, thus bringing to the fore the important yet neglected area of food translation in children’s literature which can have a profound impact not only on literary but also on translational landscapes.

A New Divergent Organocatalyst for the Synthesis of Bis Indolyl Methanes with Higher and Hetero Aldehydes with Ketones

The high yield electrophilic substitution procedure for the synthesis of bis indolyl methanes at room temperature has been carried out effectively by using a novel metal supported organo catalyst. The advantages of this method include a simple conditions, great yields, less work-up, an environmentally friendly process and reusable solid catalyst. Several bis indolyl methanes were synthesised and confirmed by IR, H1 and 13C NMR techniques. The Catalyst shortens the Indole Electrophilic Substitution reaction time.

Esophagocolonic OrVil Anastomosis After Minimally Invasive Esophagectomy.

Purpose: The classical colon substitution procedure is open surgery. Still, technological developments could allow a minimally invasive procedure that might improve patient outcomes. To present the efficacy and safety of esophagocolonic OrVil anastomosis after minimally invasive esophagectomy. Methods: This retrospective study included 10 patients with esophageal cancer treated with OrVil anastomosis (OA) between August 2017 and May 2021 at Department of Thoracic Surgery, Nanjing Lishui People's Hospital, Zhongda Hospital Lishui Branch, Southeast University, Nanjing, China and the Fourth Associated Hospital of Anhui Medical University. The patient's characteristic information and related perioperative indexes were collected from the hospital's electronic medical record system and the patients were followed up. Results: The mean operative time and median intraoperative blood loss were 530 ± 88 minutes and 200 (range: 100-300) mL, respectively. A median of 26 (range: 13-30) lymph nodes was dissected per patient. The median total duration of hospitalization and postoperative hospitalization was 32 (range: 24-64) and 15 (range: 12-42) days, respectively. Seven (70%) patients had postoperative pulmonary infections. Two (20%) patients had postoperative respiratory failure. No esophagocolonic anastomotic leakage was observed in all cases. One patient was complicated with postoperative colonicoduodenal anastomotic leakage after the operation and was cured. However, 1 (10%) of the remaining 9 patients died from colonicolonic anastomotic leakage during hospitalization. The living 9 cases were followed up, and the median overall survival time was 36 months. Conclusion: Colonic interposition for esophageal cancer is effective and safe using the minimally invasive OA technique.

Pediatric esophageal stenoses: Challenges and new surgical device promoting tension-free esophageal anastomosis.

Esophageal stenoses of childhood have a broad spectrum of underlying causes. Their treatment is usually minimally invasive by endoscopic means, but sometimes surgery is necessary in refractory cases. Techniques employed in the surgical treatment of esophageal strictures include resection of the stenotic esophageal segment or esophageal substitution procedures. Esophageal anastomosis has always been a challenge in pediatric surgery. Anastomosis complications are linked to anatomical, biological and technical aspects. Mechanical tension between esophageal ends is an important cause of complications including anastomotic leaks or dehiscence. Eleven cases of esophageal stenoses, surgically treated in the Pediatric Surgery Department of Emergency Clinical Hospital for Children 'Marie S. Curie' by a single team in 5 years, were included in the present study. The results showed that, the main causes of esophageal stenosis were represented by corrosive esophageal injury in five cases, complications of esophageal atresia repair in three cases, congenital esophageal stenosis in two cases and chemotherapy-induced esophageal necrosis in acute lymphoblastic leukemia treatment in one case. The authors also designed and presented a device facilitating esophageal anastomosis under tension. Its principle involved temporary absorption of tension at secure points of the two esophageal pouches and reallocating it in equal amounts following anastomosis while decreasing any stretch-related tissue trauma. In conclusion, this auxiliary tool is beneficial for esophageal anastomosis; however, the standard steps of the esophageal anastomosis procedure should still be considered when necessary.

Carleman Linearization and Systems of Arbitrary Depth Polynomial Recursions

New approach to systems of polynomial recursions is developed based on the Carleman linearization procedure. The article is divided into two main sections: firstly, we focus on the case of uni-variable depth-one polynomial recurrences. Subsequently, the systems of depth-one polynomial recurrence relations are discussed. The corresponding transition matrix is constructed and upper triangularized. Furthermore, the powers of the transition matrix are calculated using the back substitution procedure. The explicit expression for a solution to a broad family of recurrence relations is obtained. We investigate to which recurrences the framework can be applied and construct sufficient conditions for the method to work. It is shown how introduction of auxiliary variables can be used to reduce arbitrary depth systems to the depth-one system of recurrences dealt with earlier. Finally, the limitations of the method are discussed, outlining possible directions for future research.

Synthesis, Identification, Theoretical Study, and Effect of the New Heterocyclic System from Ciprofloxacin Derivatives on the Activity of Some Liver Enzymes

The target of this study was to synthesize several new Ciprofloxacin drug analogs by providing a nucleophilic substitution procedure that provides new functionality at the carboxylic group location. The analogs were synthesized, designed, and characterized by 1HNMR, and FTIR. The synthetic path began from the reaction of ciprofloxacin drug with morpholine to give compound[B], ciprofloxacin derivative was linked with a variety of primary and secondary amines to give compounds[B1-B9]. The above-mentioned prepared compounds [B3 and B5] were applied to liver enzymes, and the increase in the activity of these enzymes was observed. In addition, a theoretical study was conducted to study the energies and properties of the prepared compounds.

Enhancing the electrocatalytic activity of palladium nanocluster tags by selective introduction of gold atoms: Application for a wound infection biomarker detection

In this work, an unprecedented study exploring the role that slight changes into the Pd/Au proportion have in the electrocatalytic activity of bimetallic Pd-AuNPs toward the oxygen reduction reaction (ORR) is conducted. In particular, a careful control of the amount of Au atoms introduced in the cluster and the evaluation of the optimum Pd:Au ratio for getting the maximum catalytic activity is performed for the first time.First, PdNPs are synthesized by alcohol reduction in the presence of polyvinylpyrrolidone, and gold atoms are selectively introduced on vertex or corner positions of the cluster in different amounts following a galvanic substitution procedure. Average elemental analysis done relying on EDX spectroscopy allows to evaluate the Pd:Au ratio in the Pd-AuNPs obtained. Lineal sweep voltammetry and chronoamperometry are used for the evaluation of the Pd-AuNPs electrocatalytic activity toward ORR at a neutral pH compared to PdNPs and AuNPs alone. Our results indicate that, the synergy between both metals is strongly enhanced when the amount of gold is controlled and occupies the more reactive positions of the cluster, reaching a maximum activity for the NPs containing a 30% of gold, while an excess of this metal leads to a decrease in such activity, as a shelter of the PdNPs is achieved. Chronoamperometric analysis allows the quantification of the optimal Pd-AuNPs at over 6 × 109 NPs/mL levels.Such optimal Pd-AuNPs were used as tags, taking advantage of the bio-functionalities of gold present in the cluster, in a proof-of-concept electrochemical immunosensor for the detection of hyaluronidase wound infection biomarker, using magnetic beads as platforms. Hyaluronidase was detected at levels as low as 50 ng/mL (0.02 U/mL; 437 U/mg) with good reproducibility (RSD below 8%) and selectivity (evaluated against bovine serum albumin, immunoglobulin G and lysozyme). The low matrix effects inherent to the use of magnetic bead platforms allowed us to discriminate between wound exudates with both sterile and infected ulcers without sample pre-treatment. This novel electrocatalytic immunoassay has the advantage, over common methods for NP tags electrochemical detection, of the signal generation in the same neutral medium where the immunoassay takes place (10 mM PBS pH 7.4), avoiding the use of additional and hazardous reagents, bringing it closer to their use as point-of-care devices.Overall, our findings may be of great interest not only for biosensing, but also for applications such as energy converting on fuel cells, in which the ORR has a pivotal role.

Investigating the Translation Strategies Used in Rendering Cultural Bound Expressions in Barghouthy’s Memoire I Was Born There, I Was Born Her

This study investigates the translation strategies used in translating 25 cultural references and expressions in Mourid Barghouty’s autobiography ‘I Was Born There, I Was Born Here’ (2009) from Arabic into English. The results of this research may assist the trainee translators to improve their understanding of the effect of culture on the quality of the translation. The researchers adopt two theoretical models: Venuti’s domestication and foreignization (1998) and Ivir’s (1987) procedures for the translation of cultural references. This study tries to find out to what extent the translation has accounted to render the original cultural bound expressions maintaining their meaning in the target language. The researchers adopt a qualitative research since the data analysis is based on analytical and descriptive approaches. After analyzing the selected data, the researchers find out that the domestication strategy has been the most frequently-used strategy at (52%), and foreignization comes second at (48%). The procedure of substitution has been used the most (seven times), followed by literal translation and borrowing with the same number of times (six times), then defining the elements of culture (four times), then omission (twice). Lexical creation and addition have not been used at all. The findings also show that the translator has managed to capture the intended meaning sought by the original author in most extracts. The researchers recommend that translators of culture-bound expressions should be aware of the two involved cultures. This helps them to determine the cultural context in which a text takes place, so they can achieve the closest equivalents in the target text.

Are vascular grafts at risk of occlusion after total hip replacement? A systematic review of the literature.

Vascular complications during and after total hip replacement are relatively uncommon despite the close relationship between the involved structures. Previous surgical procedure of arterial reconstruction or substitution may be at higher risk of damage due to the modification in the anatomical landmarks or to the mechanical properties of the grafts different from native vessels. In literature few cases of graft occlusion or failure are reported during or soon after a total hip replacement. The aim of this review is to report them highlighting common features and risk factors. (www.actabiomedica.it)

Observation of the influence of complex SiC porous buffer layer on properties of GaN/Si(111) heterostructures

1-μm-thick GaN layers were obtained in one growth procedure on compliant SiC/Si(111) substrates using plasma-assisted molecular beam epitaxy (PA MBE). Si(111) substrates were modified by the atoms substitution technique. Prior to the atoms substitution procedure, on the one substrate, the transition porous Si layer (por-Si) was performed. The GaN layer grown on this substrate revealed better surface morphology and structural quality, less threading dislocation density, and as a result, showed lower free carrier concentration and higher carrier mobility. Moreover, the XRD study revealed less strain level in the GaN layer grown on the por-Si layer.

COMPONENT SUBSTITUTION NETWORK FOR PAN-SHARPENING VIA SEMI-SUPERVISED LEARNING

Abstract. Pan-sharpening refers to the technology which fuses a low resolution multispectral image (MS) and a high resolution panchromatic (PAN) image into a high resolution multispectral image (HRMS). In this paper, we propose a Component Substitution Network (CSN) for pan-sharpening. By adding a feature exchange module (FEM) to the widely used encoder-decoder framework, we design a network following the general procedure of the traditional component substitution (CS) approaches. Encoder of the network decomposes the input image into spectral feature and structure feature. The FEM regroups the extracted features and combines the spectral feature of the MS image with the structure feature of the PAN image. The decoder is an inverse process of the encoder and reconstructs the image. The MS and the PAN image share the same encoder and decoder, which makes the network robust to spectral and spatial variations. To reduce the burden of data preparation and improve the performance on full-resolution data, the network is trained through semi-supervised learning with image patches at both reduced-resolution and full-resolution. Experiments performed on GeoEye-1 data verifies that the proposed network has achieved state-of-the-art performance, and the semi-supervised learning stategy further improves the performance on full-resolution data.

Esophageal substitution or esophageal elongation procedures in patients with complicated esophageal atresia? Results of a comparative study

BackgroundIn newborns with complex esophageal atresia, there are situations in which a primary anastomosis cannot be safely performed. The alternative is performing a late anastomosis after the esophageal ends have gone through a period of spontaneous growth or after elongations of the distant ends of the esophagus and create an anastomosis under tension which causes risks of morbidity. An alternative to the elongation procedures is to perform a cervical esophagostomy with a gastrostomy for nutritional support and later on an esophageal replacement. The purposes of this retrospective chart review study are to report on our experience with esophageal substitution procedures in such cases, address the quality of life of a group of patients, and compare our results with those of patients who underwent esophageal elongation procedures as reported in the literature. MethodsPatients with esophageal atresia underwent esophageal replacement procedures and quality of life was assessed in a group of esophagocoloplasty patients. ResultsFrom February 1978 to July 2019, 276 children (232 colonic interpositions and 44 total gastric transpositions) were studied; the most frequent complication was cervical anastomosis leakage [70 (30.2%) esophagocoloplasty patients and 7 (15.9%) gastric transposition patients], which sealed spontaneously in all but 4 patients. The quality of life was considered excellent or good in approximately 90% of the studied 70 out of the 276 patients; the comparison with the esophageal elongation procedures showed that esophageal substitution procedures promoted excellent long-term results with normal deglutition function (98.2% of patients, versus 33.3%, 36.5%, and 62.5%, respectively from the elongation series, P <0.0001 for all comparisons). ConclusionEsophagocoloplasty or total gastric transposition is a good alternative to treat patients with complex esophageal atresia. Type of studyRetrospective study. Level of evidenceLevel III.

Unsteady RANS CFD Simulations of Sailboat’s Hull and Comparison with Full-Scale Test

The hydrodynamic investigation of a hull’s performance is a key aspect when designing a new prototype, especially when it comes to a competitive/racing environment. This paper purports to perform a fully nonlinear unsteady Reynolds Averaged Navier-Stokes (RANS) simulation to predict the motion and hydrodynamic resistance of a sailboat, thus creating a reliable tool for designing a new hull or refining the design of an existing one. A comprehensive range of speeds is explored, and results are validated with hydrodynamic full-scale tests, conducted in the towing tank facility at University of Naples Federico II, Italy. In particular, this work deals with numerical ventilation, which is a typical issue occurring when modeling a hull; a simple and effective solution is here proposed and investigated, based on the phase-interaction substitution procedure. Results of the computational fluid dynamic (CFD) campaign agree with the experimental fluid dynamic (EFD) within a 2% margin.
