Impuestos y tecnología: una respuesta a la regresividad del IVA
Authors: Hernández Leonardo , Redobran Shirley
Published: March 2022

Con una tasa de 19%, el impuesto al valor agregado (IVA) constituye una de las principales fuentes de ingreso del fisco chileno. Sin embargo, la regresividad de este impuesto constituye un problema no menor, por cuanto el IVA pagado representa una fracción más alta del ingreso disponible en los hogares de menores ingresos que en los hogares de ingresos altos. Sin pronunciarnos respecto a si se debe aumentar o disminuir la carga tributaria que soportan los consumidores, esto es, si la tasa promedio —y por ende la recaudación— debe ser mayor o menor a la actual, en este documento se proponen dos métodos para disminuir la regresividad del IVA. En particular, mediante el uso de herramientas tecnológicas actuales, los contribuyentes podrían recibir un trato diferenciado de acuerdo a sus niveles de ingreso, gravándose con una tasa menor a los grupos de menores ingresos y con una tasa más alta a los grupos de ingresos más altos. El incremento de tasa requerido para el segundo grupo es menos que proporcional, manteniéndose la recaudación y reduciéndose la regresividad del IVA. Las diferentes tasas se pueden aplicar al momento de la transacción (método ex dure) o vía una devolución de impuestos (método ex post). Para implementar estas soluciones se requiere de (1) certificados de exención tributaria vinculados a datos biométricos e integrados en tarjetas inteligentes de identificación, (2) regímenes de impuestos completamente digitales\electrónicos, (3) softwares certificados para la determinación de los impuestos y (4) transferencias digitales directas (cuenta RUT universal).

Published: March 2022

Introduction: It is well documented that some forced exercises can have bad effects on the genital system. Melatonin is a potent antioxidant that is effective in reducing the physical stress. 

Aim: The aim of this study was to evaluate the supportive effect of melatonin on the quality of spermatogenesis, including count, motility, morphology, viability, and apoptosis of sperm following a forced treadmill exercise.

Materials and methods: A total of 40 adult male Sprague-Dawley rats were used in this experimental study. All rats were divided into five groups: control group, sham M group, melatonin (M) group, forced treadmill exercise group (Ft), and melatonin with forced treadmill exercise (MFt) group. The experimental group was trained to force treadmill stress for one hour of forced treadmill exercise daily, five days weekly for eight weeks. Then the sperm quality parameters were measured after dissection and removal of epididymis. Spermatogenesis and germ cell apoptosis were evaluated using Miller and Johnsen’s score and TUNEL staining separately.

Results: Results showed the count, motility, morphology, and viability of sperm in forced treadmill-melatonin administrated group, significantly enhanced by melatonin treatment compared to the treadmill exercise group (p≤0.01). Also the number of apoptotic germ cells significantly decreased in treadmill exercised-melatonin administrated group compared to the treadmill exercised group.

Conclusions: These results suggest that administration of melatonin can protect the testis against the detrimental effect of forced treadmill exercise in adult male rats.

Authors: Georgiev Kostadin , Pecheva Aleksandra
Published: March 2022

Numerous cases of aberrant root and root canal morphology have been described, still diversion occurs more frequently in premolars and molars. To the dental researcher, the aberrations in the mandibular second premolars afford a vast field of interest. The current report presents a clinical case which demonstrates a simplified therapeutic protocol for re-treatment of Vertucci type V root canals. Endodontic access is gained by expanding the endodontic cavity. The instrumentation (preflaring and final preparation) of the root canal system is performed using predominantly hand files in order to preserve to the maximum the tactile feedback in the apical part of the ramification. Obturation is performed through hydraulic condensation. Postoperative radiographs show sufficient three-dimensional sealing of all portals of exit with excellent healing result.

Published: March 2022

Introduction: Pulp sensitivity tests are commonly used for assessment of pulp vitality. However, indirect assessment of pulp vitality by evaluation of nerve response and subjective nature are the main limitations of these tests. Pulse oximetry is used for assessment of blood oxygen saturation in medicine, and its efficacy for assessment of pulp vitality needs to be evaluated.

Aim: This study aimed to assess and compare the efficacy of pulse oximeter with a modified probe, cold test, and electric pulp test for evaluation of pulp vitality in permanent immature teeth.

Materials and methods: This cross-sectional study was conducted on 240 permanent maxillary incisors in four groups based on the type of tooth (central and lateral incisors) and degree of root development (complete or incomplete). Also 40 endodontically treated central and lateral incisors teeth in two groups were evaluated as negative controls. Pulp vitality was assessed by an expert clinician using pulse oximeter, cold test, and electric pulp test. Based on the true and false positive and negative responses, the sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood, diagnostic accuracy, and diagnostic odds ratio were calculated.

Results: The pulse oximeter showed diagnostic accuracy of 98.7% in the permanent central incisors with complete and incomplete roots and 100% in the permanent lateral incisors with complete and incomplete roots. The diagnostic accuracy of the electric pulp test was 76.2% and 92.5% in the incomplete and complete central incisors, respectively, and 76.2% and 83.7% in the incomplete and complete lateral incisors, respectively. The cold test had a diagnostic accuracy of 85% and 92.5% in the incomplete and complete central incisors, respectively, and 91.2% and 88.7% in the incomplete and complete lateral incisors, respectively.

Conclusions: The findings of this study showed that pulse oximetry has a higher specificity and better accuracy than the cold test and the electric pulp test in assessing the pulp vitality in the diagnosis of vital teeth and should be introduced as a suitable method for this purpose and preferred to the cold and electric pulp tests for more evaluation to diagnose pulp vitality.

Published: March 2022

The capacity of a novel bacterial 6-phytase variant (PhyG) to totally replace dietary supplemental inorganic phosphate (Pi) in broilers aged one day old was evaluated using a phased dosing strategy and reduction in dietary phytate. A total of 1,248 one-day-old Ross 308 broilers were assigned to 24 pens (52 birds/pen, 12 pens/diet, six each males and females) in a complete randomised block design with a 2×2 factorial arrangement (two diets, two genders). Diets comprised: (1) a positive control (PC) based on maize, wheat and soybean meal, containing Pi from monocalcium phosphate and 2,000 XU/kg xylanase, and; (2) an inorganic phosphate-free (IPF) diet equivalent to PC but with reduced Ca (-2.0 g/kg) and supplemented with PhyG at 3,000, 2,000 and 1000 FTU/kg from d 0 to 11 (3.4 g/kg phytate-P (PP)), d 11 to 22 (3.3 g/kg PP) and d 22 to 42 (2.8 to 2.9 g/kg PP), respectively. A negative control was not included for animal welfare reasons. Tibias were collected on d 11, 22 and 42 from two birds/pen. Treatment IPF maintained or improved average daily gain (ADG), average daily feed intake and feed conversion ratio (FCR) vs PC during all phases; Body weight was higher in the IPF treatment than the PC at d 42 (+3.97%, P<0.01) and ADG during d 0 to 42 (+4.10%, P<0.01). Overall (d 0 to 42), treatment IPF improved FCR in males (-5 points vs PC, P<0.05) but not females. Tibia ash was equivalent in IPF and PC throughout, with no gender differences. In conclusion, when applied as a phased dosing strategy to diets with graded reduction in PP content, PhyG totally replaced supplemental Pi during all growth phases in males and females.

Many dishwasher manufacturers are in search of innovative solutions for issues such as washing performance, energy efficiency, water consumption and noise. The most critical place to make these improvements is in the spray arm design. With a good spray arm design, it can be reduced water consumption, energy consumption, and noise. In this study, we focus on a new spray arm design (studied by Arçelik) that increases efficiency. Also, we have obtained a geometrical interpretation of the new spray arm motion. We investigate the path followed by the new spray arm in $ 3- $dimensional Minkowski space and its projection on a plane. Finally, we present its three-dimensional and two-dimensional images.

We face a rigidity problem for the fractional $ p $-Laplace operator to extend to this new framework some tools useful for the linear case. It is known that $ (-\Delta)^s(1-|x|^{2})^s_+ $ and $ -\Delta_p(1-|x|^{\frac{p}{p-1}}) $ are constant functions in $ (-1, 1) $ for fixed $ p $ and $ s $. We evaluated $ (-\Delta_p)^s(1-|x|^{\frac{p}{p-1}})^s_+ $ proving that it is not constant in $ (-1, 1) $ for some $ p\in (1, +\infty) $ and $ s\in (0, 1) $. This conclusion is obtained numerically thanks to the use of very accurate Gaussian numerical quadrature formulas.

Internal gravity waves are propagating disturbances in stably stratified fluids, and can transport momentum and energy over large spatial extents. From a fundamental viewpoint, internal waves are interesting due to the nature of their dispersion relation, and their linear dynamics are reasonably well-understood. From an oceanographic viewpoint, a qualitative and quantitative understanding of significant internal wave generation in the ocean is emerging, while their dissipation mechanisms are being debated. This paper reviews the current knowledge on instabilities in internal gravity waves, primarily focusing on the growth of small-amplitude disturbances. Historically, wave-wave interactions based on weakly nonlinear expansions have driven progress in this field, to investigate spontaneous energy transfer to various temporal and spatial scales. Recent advances in numerical/experimental modeling and field observations have further revealed noticeable differences between various internal wave spatial forms in terms of their instability characteristics; this in turn has motivated theoretical calculations on appropriately chosen internal wave fields in various settings. After a brief introduction, we present a pedagogical discussion on linear internal waves and their different two-dimensional spatial forms. The general ideas concerning triadic resonance in internal waves are then introduced, before proceeding towards instability characteristics of plane waves, wave beams and modes. Results from various theoretical, experimental and numerical studies are summarized to provide an overall picture of the gaps in our understanding. An ocean perspective is then given, both in terms of the relevant outstanding questions and the various additional factors at play. While the applications in this review are focused on the ocean, several ideas are relevant to atmospheric and astrophysical systems too.
Speech Recognition via IPA-Based Phonetic Data Coding and Analysis
Authors: Khadimally Seda
Published: March 2022

In the first cycle of this phenomenological investigation, where the researcher conducted an extensive coding process (i.e., descriptive coding), all of the previous codes were identified under textural descriptions. This first cycle of coding was completed with codes having been formed following an initial deconstruction phase of the raw data given by all participants. Next, a plethora of emerging themes was identified under structural descriptions. The next step comprised the second cycle of coding: pattern coding. Where the second type of coding in the coding phase was involved, the researcher found all participants' common speech patterns by meta coding. The researcher applied the meta coding technique via IPA-based meta transcriptions. From a linguistic perspective, the researcher employed the type of data analysis that had not previously been exercised in the CALL field and in the realm of phenomenological study design: phonics in data analysis.

Authors: Stella Simone , Tirloni Erica , Bernardi Cristian , Acerbis Greta , Manginelli Teresa
Published: March 2022

The study evaluated the outcomes of cattle liver postmortem examination (64,766 animals) obtained from three slaughterhouses (two located in Lombardy, Northern Italy, and one in Puglia, Southern Italy) through the period 2016-2020. The frequency of specific lesions determining liver condemnation was calculated and the influence of several factors (animal age/category, geographical area, season, plant) was considered. A mean prevalence of 8% was observed, with a significant difference among the plants (range 6.4-12.8%). A significant difference was observed among the animal categories and age classes, with higher condemnation rates in animals aged more than 30 months (mainly cows). Steatosis was the most frequent lesion observed in cows (about half of the total), whereas liver abscesses were the most diffused in younger animals (half of the total in young bulls). Other frequently observed lesions were distomatosis and perihepatitis. A different pattern was observed between the two geographical areas, with a higher prevalence of steatosis in Lombardy (mainly intensive dairy farming), and of distomatosis in Puglia (animals mainly grazed on pasture). The season influenced the prevalence of lesions, and especially of steatosis (higher in summer). A different lesion prevalence was also observed between the two plants on similar animal populations, suggesting a difference in the notification and classification procedure among the plants. This study highlights the importance of a proper sharing procedure of the information obtained from the post mortem inspection in order to facilitate an optimal use of Food Chain Information and a useful feedback for farmers.

Authors: Swanepoel Karen , Saurombe Musawenkosi D.
Published: March 2022

Background: Private schools in South Africa are currently faced with the challenge of retaining a talented pool of teachers. An employee value proposition (EVP) could assist private schools in reducing teaching staff turnover.Aim: The aim of this study was to investigate the significance of an EVP in the retention of teachers at three selected South African private schools. The study thus sought to answer the following question: What is the significance of an EVP in the retention of teachers at three selected South African private schools?Setting: Time and money are spent on the recruitment and development of teachers. High turnover of teachers reduces all staff recruitment and staff development efforts to useless financial expenses.Methods: A qualitative research approach was followed. Semi-structured interviews were used to gather data from teachers at three different private schools in Johannesburg.Results: The findings showed that most private schools lack a clear and differentiated EVP. Despite their importance, EVPs were often not clearly communicated to staff members and the value of EVPs in the retention of teachers was mostly underestimated.Conclusion: The research highlighted the deficiencies in the EVPs of most schools. It also emphasised the backlog in the retention of teachers caused by a lack of a proper EVP.

Contamination of soils with potentially toxic metals (PTMs) is an environmental problem. In this study, sorption of cadmium (Cd), zinc (Zn) and copper (Cu) in four soil profiles (two Fluvisols, one Gleysol, and one Cambisol), representing the dominant soils of the Zagreb aquifer system, were studied using a multi element laboratory batch test. Mathematical expressions were applied to establish the relationship between the concentration of the adsorbent in the liquid phase and the solid phaSe at equilibrium and in laboratory conditions. The study revealed that the investigated soils have a higher capacity to sorb Cu than Zn and Cd. The most significant physicochemical characteristics of soils, influencing sorption, are pH, carbonate content (minerals) and organic matter. Although all PTMs in all analyzed soils had a similar sorption capacity, the variation of sorption was higher in the siltic soils (Fluvisols) compared with the texturally finer (loamic) Gleysol and Cambisol soils, as well as in the subsoil horizons compared with the topsoils. Results indicate that sorption of PTMs is more influenced by physicochemical characteristics at different soil depths than by soil type, which is confirmed with a higher affinity for Zn and Cd bonding in the topsoil horizons. Also, it has been shown that Cd may pose more of a threat to soils and groundwater due to its toxicity and relatively high mobility in comparison with Zn and Cu.

The pre-Neogene basement of the Slavonia-Srijem Depression (eastern Croatia) is composed of various types of igneous, metamorphic and sedimentary rocks. Here we present the petrography and geochemistry of a heterogenous group represented by two types of alkali granite, granite, syenite, rhyolite and orthogneiss. The alkali granite type 1 has an A-type geochemical affinity: a ferroan character, high alkali content, high concentration of rare earth elements (REE3+), Rb, Zr, Nb and Y, and low CaO, MgO, P2O5, Ba, Sr and Eu contents. The syenite has similar characteristics, but displays enrichment in Ba, K, Eu and Zr, which could be a consequence of feldspar and zircon accumulation. The alkali granite type 2 is an A-type granite but differs from the alkali granite type 1 in having lower K2O and Rb, accompanied by higher Na2O and Sr concentrations, possibly resulting from alteration or a different parental magma/evolutionary process. The granite and rhyolite are distinguished from both types of alkali granite by their magnesian character, lower Zr, Nb and Y concentrations, less pronounced Eu negative anomaly, as well as higher Ba, Sr and LREE/HREE. The orthogneiss displays differences in major element chemistry compared to the alkali granite type 1, but has similar trace element and REE patterns. The alkali granites are characterized by Y/Nb<1.2, indicating an ocean island basalt-like source, while the granite originated from melting of a crustal, probably metasedimentary source. The A-type granites could belong to the Late Cretaceous A-type magmatism of the Sava Zone, while the granite is significantly different from the Sava Zone A-type granites as well as the other rocks investigated in this study.

A landslide inventory was created for an area of 22.6 km2 near Petrinja city in northern Croatia, based on the high-resolution LiDAR data complemented by orthophoto maps. A total of 216 landslides were identified, covering 2.91 % of that area. Landslide polygons were overlain on geological units based on the Basic map of SFRY at a scale of 1:100,000 that is the largest scale geological map available for the whole of Croatia. The relationship between landslides and geological units was expressed as a landslide index. Three geological units displayed increased landslide susceptibility. A Pliocene unit clearly had the largest susceptibility, followed by a Palaeocene-Eocene unit, and finally a Badenian unit. Landslide density was analyzed within these geological units to identify influencing factors for landslide initiation. Each geological unit revealed different influencing factors. The Pliocene unit is mostly influenced by bedding plane orientation and local relief. Heterogeneousness lithology is the dominant factor in the Paleocene-Eocene unit, while the Badenian unit demonstrated the least certain interpretation as there are multiple factors involved. The forest road is presumed to be crucial, followed by spring occurrences and proximity to the tectonic boundary. The basic geological map of SFRY proved to be a viable source of geological information for the creation of landslide susceptibility maps at a scale of up to 1:100,000, but with limitations in the case of lithologically heterogeneous geological units. Larger scale maps require more detailed research as landslide susceptibility factors vary in each geological unit.

As a society known for its rich tribes, cultures, enis, groups, languages, islands, and so on, it is natural that Indonesia is said to be one of the countries on the world's most multicultural planet. The passing of Law No. 44 of 2008 on Pornography as a hard success among Islamism penetrated the national legislation of Indonesia. As a result, the group of people who disagreed and disagreed with the passage of Law No. 44 of 2008 made various resistance efforts to overturn the Law. The resistance they make from protests through demonstration movements, politics, economics, to efforts to take legal routes. As a result, to this day the Law is only as a documentation of Indonesia's national legislation, and almost no longer gets the attention of the public and law enforcement in Indonesia. In connection with that, this paper will read the existence of Law No. 44 of 2008 on Pornography in the perspective of legal sociology, both in the discussion of legal science in general and in discussions of Islamic-Sharia law.

The Cross-flow turbine is one type of hydroelectric power plant that is frequently used. This is an experimental study with the goal of analyzing the power and efficiency produced by the turbine as a result of runner rotation adjustments. The runner rotation variations used are 261 rpm, 300 rpm, 320 rpm, 340 rpm, 360 rpm, 380 rpm, 392 rpm, and 423 rpm with a head as high as 5 meters and an incoming water discharge of 0.2 m3/s. The best results shown when runner rotate at 423 rpm. It's showed the maximum power 788.85 Watt and best efficiency 80.49%. The power and efficiency produced by a runner are proportional to the rotational speed of the runner; the higher the runner's rotation, the greater the power and efficiency produced. To summarize, the best way to achieve the best turbine performance is to maximize runner rotation.

Talas merupakan salah satu tanaman yang mengandung kadar pati yang tinggi pada bagian umbinya. Bahkan kadar pati pada umbi talas lebih tinggi dibandingkan dengan kadar pati yang terdapat pada umbi singkong.Umbi talas memiliki kemampuan yang tinggi untuk mengikat air karena mengandung granula pati yang mempunyai sifat elektrostatik dengan molekul kasein (COO--- Ca2+ -- COO-). umbi talas memiliki keunggulan yaitu kemudahan patinya untuk dicerna karena memiliki ukuran granul pati yang sangat kecil yaitu 1 – 4 μm. Tujuan dari penelitian ini adalah untuk mengetahui kompresibilitas granul pati talas dengan metode granulasi basah.. Dalam penelitian ini menggunakan metode eksperimental dengan membuat granul dari pati talas yang akan di uji kompresibilitas. Hasil penelitian yang di dapatkan uji kompresibilitas granul pati talas dengan metode granulasi basah yaitu 24%. Pada hasil yang di dapat menunjukan bahwa komprebilitas dari granul pati talas kurang baik karena hasil kerapuhan kurang dari 20%. Sehingga perlu di teliti kembali kadar pati yang sesuai sebagai alternatif sumber bahan tambahan sediaan farmasi dari bahan alam lokal.
