Analysis of standard systems with solar monitoring systems
Authors: Alak Ali Osman , Karakaya Abdulhakim
Published: January 2023

With the increase in the need for electrical energy in the world, electricity is tried to be generated by various methods. Some of these methods cause global warming and environmental pollution to increase. Therefore, it is aimed to generate electricity using renewable energy sources instead of fossil fuels. The sun is one of these renewable energy sources. Electricity generation with solar energy is one of the methods that have become quite common in recent years. One of the most important considerations required to achieve maximum efficiency in solar power and electricity generation is to ensure that the rays are perpendicular to the panel. When this is achieved, the depreciation time of the system will be reduced and electricity generation will be carried out with high efficiency from these panels with limited service life. To achieve this, various solar tracking systems are designed. In this study, the analysis of fixed systems was performed by comparing them with single- and dual-axis solar tracking systems. Comparisons were made using a design and simulation software (PVSOL) program for photovoltaic systems. In these comparisons, the effects of single- and dual-axis solar tracking methods on depreciation time compared to fixed systems were examined.

Objectives

Isolated ovarian agenesis in the absence of Mullerian duct anomalies are rare events which are usually discovered after menarche and incidentally in the context of an intervention for other indications, such as laparoscopy or assisted reproduction techniques.

Case presentation

We hereby present a case of unilateral ovarian agenesis in the presence of the ipsilateral fallopian tube.

Conclusions

Older studies had reported an incidence of true congenital unilateral ovarian agenesis to be 1 in 11,241 females Sivanesaratnam V. Unexplained unilateral absence of ovary and fallopian tube. Eur J Obstet Gynecol Reprod Biol 1986;22:103–5, but this is likely an understatement given the increase of relevant literature in recent years and the frequency of laparoscopy nowadays.

Published: January 2023

The development of subways in cities has provided great comfort to the citizens, but it has brought adverse effects to the residents of the buildings adjacent to the subway lines. The main effects are Structure Borne Noise (SBN) and Structure Borne Vibration (SBV), which are identified as environmental challenges. In this research, the extent and seriousness of SBV and SBN annoyances to people were investigated. This is made in two steps; first a thorough field test was made to evaluate the level of train-induced noise and vibration; then, a comprehensive investigation was made on the level of people annoyance from train-induced vibration and noise, using results obtained from interviews and questionnaires. The results obtained indicate that health concerns, economic losses, building damages and social harms were the most important factors, which cause annoyance of the citizens. These annoyances caused citizens to take their complaints to judiciary system in the world. In the second part of this research, the effectiveness and sufficiency of the current laws and legislation to protect the citizen against SBV/SBN annoyance are evaluated. The results indicate that there are limitations in the current laws in regard to crime determination, criminal identification, estimation of damages to citizens, citizen rights regarding the annoyance caused by SBV/SBN. Also, there is a lack of legal awareness among the citizens who do not know how to get their legal rights. The results of this research showed that the judicial bodies should improve and extend the current laws and make more low-enforcement to protect people against the growing problem of SBV/SBN. Also, there is a need to make people more familiar with their civil rights in regard to SBN and SBV.

Published: January 2023

Hookah smoking has become very popular in Iraq among women and men. Hookah tobacco contains natural radioactive elements, such as radon, radium, and uranium, as well as toxic elements, such as polonium, which are released during the combustion of tobacco and are inhaled by smoking. Most reviews focus on hookah tobacco, and only a few have investigated the blood of hookah smokers. In this study, a CR-39 detector was used to measure radon, radium, and polonium concentrations and conduct risk assessments in female hookah smokers of different ages. The results show that the concentrations of radon-222, polonium-218, and polonium-214 varied between 61.62 and 384.80, 5.45–33.64 on the wall of the can, and 2.43–15.00 Bq/m3 on the surface of the detector, respectively. The effective radium-226 concentration varied between 4.52 and 56.31 Bq/kg. The absorbed effective dose varied between 1.55 and 9.71 mSv/y, which is within the recommended limit (3–10 mSv/y) by International Commission on Radiological Protection (ICRP). The average case of lung cancer 107.91 cppp, which exceeds the European Union (EU) limit (96.9–104.8 cppp). The rates of radon activity and radon exhalation from the intake of a natural radionuclide due to hookah smoking in a female’s blood were calculated and discussed. This study aimed to establish preliminary results on the risks of radioactivity concentrations and assess the dose in the blood of women who smoke hookah and assess the possibility of developing cancer.

Authors: López del Castillo Wilderbeek Francisco Leslie
Published: January 2023

La dependencia de las agencias de noticias es una cuestión fundamental en los medios de comunicación, especialmente en el caso de los medios digitales nativos. Esta investigación se ha propuesto el análisis cuantitativo de la publicación de contenidos de cuatro medios nativos (El Confidencial, El Español, Voz Pópuli, El Diario.es) pero firmados por la agencia de noticias Europa Press. Se ha aplicado cuantificación del total de contenidos publicados, firmados por Europa Press y se ha consultado datos de tráfico web. Sobre esta cuantificación se ha realizado visualización de datos para la extracción de resultados relevantes detectando que la producción general de contenidos descendió durante el mes de agosto en los cuatro medios analizados. También se ha observado que cada medio tiene un umbral estable de contenidos elaborados por Europa Press respecto la producción total. Finalmente, los resultados obtenidos señalan que existe una correlación negativa entre publicación de contenidos de Europa Press y tráfico web.

Parkinson's disease (PD) is characterized by multiple symptoms including olfactory dysfunction, whose underlying mechanisms remain unclear. Here, we explored pathologic changes in the olfactory pathway of transgenic (Tg) mice of both sexes expressing the human A30P mutant α-synuclein (α-syn; α-syn-Tg mice) at 6–7 and 12–14 months of age, representing early and late-stages of motor progression, respectively. α-Syn-Tg mice at late stages exhibited olfactory behavioral deficits, which correlated with severe α-syn pathology in projection neurons (PNs) of the olfactory pathway. In parallel, olfactory bulb (OB) neurogenesis in α-syn-Tg mice was reduced in the OB granule cells at six to seven months and OB periglomerular cells at 12–14 months, respectively, both of which could contribute to olfactory dysfunction. Proteomic analyses showed a disruption in endocytic and exocytic pathways in the OB during the early stages which appeared exacerbated at the synaptic terminals when the mice developed olfactory deficits at 12–14 months. Our data suggest that (1) the α-syn-Tg mice recapitulate the olfactory functional deficits seen in PD; (2) olfactory structures exhibit spatiotemporal disparities for vulnerability to α-syn pathology; (3) α-syn pathology is restricted to projection neurons in the olfactory pathway; (4) neurogenesis in adult α-syn-Tg mice is reduced in the OB; and (5) synaptic endocytosis and exocytosis defects in the OB may further explain olfactory deficits.

SIGNIFICANCE STATEMENTOlfactory dysfunction is a characteristic symptom of Parkinson's disease (PD). Using the human A30P mutant α-synuclein (α-syn)-expressing mouse model, we demonstrated the appearance of olfactory deficits at late stages of the disease, which was accompanied by the accumulation of α-syn pathology in projection neurons (PNs) of the olfactory system. This dysfunction included a reduction in olfactory bulb (OB) neurogenesis as well as changes in synaptic vesicular transport affecting synaptic function, both of which are likely contributing to olfactory behavioral deficits.

Particleboard is a product of wood technology engineering made of wood particles and other lignocellulosic materials which are bonded with synthetic adhesives. As an information, utilization of natural adhesive for particleboard is still limited. This study aimed to determine the influence of hybrid adhesive made from citric acid and sucrose for particleboard properties composed of Sengon veener by-products and sorghum stalk. The hybrid adhesive content used was 15% of citric acid and 25% of sucrose that calculated from the dry weight of particles. The mixture ratio of hybrid adhesive for both citric acid and sucrose were 100:0, 75:25, 50:50, 25:75, and 0:100 (% w/w). The manufacture of particleboard was set on target density of 0.8 g/cm3 under a press temperature of 200o C for 10 minutes. Mostly, the properties of particleboard were shown to be affected by the adhesive content and composition ratio between citric acid and sucrose and met the Japan Industrial Standard A 5908:2003. The value of modulus of elasticity, modulus of rupture, internal bond, and screw holding were ranged about 1.21-3.49 GPa, 12.77-20.24 MPa, 0.18-0.90 MPa and 167.71-321.27 N. Particleboard with 15% of citric acid content and the mixture ratio both citric acid and sucrose of 50:50 has the best physical and mechanical properties and met the requirement of Japan Industrial Standard A 5908:2003.

Representações da Violência em O frío azul, de Ramón Caride Ogando
Authors: Saraiva Fino Francisco
Published: January 2023

A novela O frío azul (2007), do escritor galego Ramón Caride Ogando, constitui um exemplo significativo da propensão da narrativa histórica pós-moderna para a reflexão sobre o esbatimento de fronteiras entre domínios do conhecimento como a história e a literatura. Nesse contexto, a interdiscursividade assume-se para o autor tanto enquanto horizonte de reencontro ficcional com o arquivo disponível como cenário de subversão criativa das referências aí encontradas. Na obra de Ramón Caride, esse olhar diverso revela-se, entre outros aspetos, na representação da violência, de que nos ocuparemos a partir do estudo de três dimensões intercomunicantes: o espaço, a soberania e o maravilhoso.
La dinámica situacional de los actos de infracción de las normas. Un test parcial de la teoría de la acción situacional en el ámbito de la competición deportiva
Authors: Teijon Alcalá Marco
Published: January 2023

En este estudio se testa empíricamente una de las principales hipótesis de la Teoría de la Acción Situacional (TAS) en el contexto de la actividad/competición deportiva. Se analiza si los actos de infracción de las normas (deportivas) son el resultado de la participación (exposición) de deportistas con tendencia a la infracción de esas normas (propensión criminal) en deportes (entornos) especialmente criminógenos. Para ello, se utiliza una muestra (n=329) de deportistas en activo que compiten en diferentes disciplinas y a diferentes niveles deportivos. Los resultados revelan que tanto la propensión criminal individual como el carácter criminógeno del tipo de deporte practicado son por sí mismos factores causalmente relevantes de conductas antideportivas. Los resultados también revelan que los efectos de la propensión individual son mayores para los deportistas que compiten en deportes especialmente criminógenos. Se analizan y discuten los resultados.
Naturaleza jurídica de la normativa relativa al registro de delincuentes sexuales a la luz de la jurisprudencia del TEDH y crítica a toda la regulación
Authors: Fernández Cabrera Marta
Published: January 2023

La naturaleza jurídica de la normativa relativa al Registro Central de Delincuentes Sexuales es una cuestión controvertida que ha enfrentado a la doctrina y a la jurisprudencia. Hay autores que han afirmado que estamos ante verdadero Derecho penal despojado de sus garantías mientras que la jurisprudencia le ha negado este carácter tanto al registro como a la inhabilitación para el ejercicio de profesiones con menores que dicha inscripción conlleva. El tema es de suma trascendencia, pues de la naturaleza jurídica se derivan los derechos y garantías que debe llevar aparejada una institución. Así, si afirmamos el carácter penal, o al menos, sancionador, de todo o parte de la regulación esta deberá respetar principios como el de legalidad o proporcionalidad. El presente trabajo va destinado a dilucidar esta cuestión a la luz de la jurisprudencia del Tribunal Europeo de Derechos Humanos, así como a sistematizar toda la crítica que se ha formulado sobre dicha institución.
La prevención de la radicalización en el ámbito educativo: un análisis crítico sobre la pretensión de involucrar al profesora en la lucha contra el terrorismo
Authors: Fernández Abad Carlos
Published: January 2023

El "discurso sobre la radicalización" se presenta actualmente como el marco de referencia para pensar e intervenir sobre el terrorismo de inspiración yihadista. En este sentido, su marcada naturaleza preventiva ha propiciado que la lucha contra el terrorismo deje de ser una responsabilidad exclusiva del Estado y, en contraposición, se extienda también a otros agentes que no están vinculados al ámbito de la seguridad. El objetivo principal de este artículo reside en examinar críticamente cómo, al hilo de este discurso, los poderes públicos han buscado involucrar paulatinamente a los profesores en la doble tarea de identificar posibles casos de radicalización y promocionar determinados valores como medio para crear una suerte de resiliencia frente al extremismo. argumentándose a partir de la evidencia empírica disponible que tal pretensión ha generado toda una serie de cambios en la relación educativa que comportan severas consecuencias para los alumnos considerados en riesgo de radicalización.
Política conciliadora y política como hostilidad. Una lectura en torno a Carl Schmitt y Richard Rorty
Authors: Arcos Fuentes Israel
Published: January 2023

En el artículo se exponen las diferentes concepciones políticas de Richard Rorty y Carl Schmitt. Concretamente lo que, para el caso de Schmitt, denominamos una política de la hostilidad, fundada en el antagonismo y en la necesidad de configurar un enemigo para poder reafirmar un demos pensado a la manera esencialista, y lo que, en Rorty, puede llamarse una política conciliadora, la cual busca confraternizar con los extraños invitándolos a formar parte de una comunidad liberal, contingente y abierta que trate de erradicar lo máximo posible el sufrimiento y las injusticias. Comparadas estas dos perspectivas de pensar políticamente, asentadas en distintos modos de comprender la naturaleza humana, la configuración de la comunidad y la visión sobre el diferente, serán volcadas al presente para tratar de reflexionarlo con algunas de sus ideas.

Published: January 2023

The present work analyzes the effect of different Zr contents on the microstructure and thermal behavior of non-irradiated UO2. A set of Zr-doped UO2 (0, 20, 40, 80, and 100 wt%) pellets was prepared via solid-state synthesis by mimicking the chemical bonding between ZrO2 and UO2. After sintering, the Zr-doped UO2 monoliths were characterized by scanning electron microscopy, Raman spectroscopy, and X-ray diffraction. Oxidation of the Zr-doped UO2 samples has been monitored by thermogravimetric analysis. Results of thermal behavior under air and low oxygen partial pressure show a profound effect of delayed oxidation with the addition of Zr to UO2 and then an increased oxidation resistance of UO2 to U3O8 when compared to pure UO2 pellet.

Peningkatan CO₂ menjadi penyebab utama perubahan iklim dan pemanasan global. Karbon biru/blue carbon menjadi topik utama pada ekosistem di wilayah pesisir, karena ekosistem ini mampu mengurangi buangan gas CO₂ dengan menyerap dan menstabilkan karbon dalam wujud senyawa organik, salah satunya adalah lamun. Lamun di Pulau Bintan mencakup area yang cukup luas. Penelitian dimulai sejak Maret hingga Mei 2020 di Pulau Bintan, dengan 4 stasiun pengamatan (Pengudang, Tanjung Siambang, Busung dan Malang Rapat) dan bertujuan untuk mengetahui struktur komunitas dan cadangan blue carbon serta parameter kualitas air pada ekosistem lamun. Teridentifikasi beberapa spesies lamun adalah Thalassia hemprichii, Enhalus acroides, Cymodocea rotundata, Syringodium isoetifolium serta Halophila ovali. Perhitungan cadangan karbon lamun adalah dengan menghitung karbon cadangan yang ada pada sedimen dan habitatnya, Dari penelitian diperoleh besaran karbon yang terkandung dalam lamun terbesar di Pengudang 245.03 gC/m² atau 348.26 MgC/ha. Biomassa tertinggi pada Pengudang sebesar 1283.48 gDW/m², sehingga dapat disimpulkan bahwa lamun yang mempunyai peran dominan sebagai penyerap blue carbon di Pulau Bintan Provinsi Kepulauan Riau adalah di stasiun Pengudang.

Published: January 2023

Saat ini pemberian pakan pada umumnya masih mengandalkan sumber daya manusia yang bersifat tenaga manual. Oleh karena itu dirancang suatu alat pemberian pakan ikan yang dapat bekerja secara otomatis sesuai dengan waktu atau jadwal pemberian pakan dan jumlah atau takaran pakan. Kegiatan pemberian pakan merupakan salah satu aspek penting dalam budidaya ikan. Pemberian pakannya sederhana dengan menaburkan pakan ikan langsung ke kolam atau tambak secara rutin setiap hari. Sehingga diperlukan suatu rancang bangun alat automatic fish feeder yang lemparannya dapat dikontrol dan bisa menyebarkan pakan secara merata. Prinsip kerja rancang bangun alat tersebut adalah dengan melemparkan pakan menggunakan baling-baling yang berputar kencang hingga mencapai jarak minimum dan putaran baling-baling dapat dikontrol sehingga lemparan pakan dapat disesuaikan sesuai diameter kolam yang digunakan, alat ini menyebarkan pakan secara merata dengan menggunakan gerak rotasi bolak-balik sebesar 30º.Pada rancang bangun alat automatic fish feeder ini terdapat sistem mekanik mesin yang terbagi menjadi tiga bagian, yaitu sistem arah lemparan, sistem penyuplai pakan, dan sistem lemparan pakan. Prinsip kerja sistem arah lemparan yaitu dinamo AC 12V 4W 5RPM menggerakkan corong yang dipasang stick yang terhubung pada pully yang terpasang pada dinamo AC sehingga sistem dapat menengok ke arah kanan dan kiri, prinsip kerja sistem penyuplai pakan yaitu dinamo AC 12V 4W 30RPM menggerakan pendorong pakan yang dihubungkan stick yang dihubungkan pada pully yang terpasang pada dinamo AC sehingga sistem mendorong pakan dan menjatuhkannya ke atas baling-baling, dan prinsip kerja sistem lemparan pakan yaitu dinamo DC 12V 1A 15000 RPM menggerakan baling-baling 8 daun yang AS-nya dihubungkan dengan pully baling-baling yang ukurannya sama dengan ukuran pully pada AS dinamo DC yang disambungkan dengan vanbelt karet sehingga baling-baling berputar kencang dan memukul pakan yang didorong jatuh diatasnya oleh sistem penyuplai pakan.Pada umumnya pemberian pakan masih didominasi oleh sumber daya manusia atau bersifat manual. Alat ini juga dapat dikontrol menggunakan android dengan menggunakan aplikasi bardi smarthome yang harus terhubung dengan wifi yang ada, dalam aplikasi terdapat pilihan untuk mengontrol (on/off, countdown timer, schedule).

Authors: Szumski Krzysztof
Published: January 2023

The rivalry of great powers between the United States and China embraces all regions of the world, including Southeast Asia and especially the Philippines. The President of the Philippines Rodrigo Duterte (2016–2022) at the beginning of his presidency started to diminish the dependence of the country on former colonial power the US and to improve relations with China. Duterte hoped for the increase of economic cooperation and support of Beijing for modernization of infrastructures. Despite some successes in his policy, Duterte finally started to search again for support from the US. It was the result of extremely strong links and dependency between armed forces of Philippines and United States and generally very strong pro American filling of many Filipinos, the second reason was slowness of realization of some Chinese investments in the country, brutality and aggressiveness of Chinese coast guards towards Philippine fishers, and probably also some weakness in Chinese policy to the Philippines. Finally, Duterte obtained good results. The US confirmed readiness for military support in case of foreign aggression (especially in the South China Sea) and China was involved in political and economic cooperation with the Philippines.
Managing Emotions During Social Protests and the Political Subjectivity of the Protesters
Authors:   Nicolaus Copernicus University (Poland), Bäcker Roman
Published: January 2023

The paper’s aim is to check whether there is a relationship between the effectiveness of emotion management techniques and the protesters’ subjectivity level in Poland. In this case, it is necessary to analyse selected significant social protests in terms of the emotions felt by the ruling elites, the emotions they evoke among the protesters, and the level of political subjectivity possessed by the latter. In June 1956, the technique of masking emotion management was used effectively. The intensification technique in October was fully effective. In December 1970, only the use of the intensification technique brought results. In June 1976, the masking technique proved to be effective within a limited time range. In the summer of 1980, the party-state apparatus was not able to effectively manage emotions. The breakthrough was the introduction of martial law and forcing a significant part of society to be submissive and conformist. Managing emotions by intensifying them during the Women’s Strike proved to be partially effective. Crossing the threshold of subjectivity by opposition social groups makes the management of emotions generally ineffective. The paper offers an innovative research design for analysing the relationships between the management of emotions and the political subjectivity level.

Case study on soil-reinforced embankment slope stability with natural fibre additives
Authors: Kumar Saurabh , Roy Lal Bahadur
Published: January 2023

In this work, an attempt was made to study the influence of jute fibre reinforcement with the help of three case studies. The first case study described laboratory model testing and numerical analysis performed on a modelled slope that simulated an existing embankment that failed on many occasions following overnight heavy rainfall. The second case study discussed how vegetation may minimise the likelihood of soil separation and the velocity of surface run-off by decreasing surficial soil erosion. Jute geotextiles have excellent hydrophilic characteristics that aid plant development; for this reason, they were used in the case study. The third case study developed a multi-fibre approach to traditional geotextiles to create an eco-sustainable product(s) with superior geotechnical qualities for improving the efficiency of earthen structures using soft revetments. The conclusion of these case studies expressed the novel objective of improvement of embankments with stability analysis. This research also involved soil sample testing and numerical modelling using the GeoStudio software suite. The slope model considers reinforcement with different numbers of rows of jute tassels on the embankment for enhanced stability and factor of safety. The presence of jute fibre geotextiles results in better performance in the stabilisation of soil and the minimum value of deformation and maximum value of the factor of safety.

Published: January 2023

The process of learning and teaching involves the organization of the interaction among teachers, students, and content. The focus of this study was to enable the student teachers’ experience of deliberate practice to improve their organization of specific content and develop practice skills in classroom environments. This study, which adopted a holistic single-case method, examined fourth-year student classroom teachers’ content organization skills in a teaching practicum course. The study was conducted with 11 fourth-year student teachers, who were attending a teaching practicum course, and data were collected through an open-ended test, a semi-structured interview form, and lesson plans. The student teachers were provided with four weeks of training on the components of concepts and generalizations, and with information selecting-organizing-integrating (SOI) techniques. The participants were asked to prepare lesson plans and implement them in the classroom environment. Over six weeks, the researchers provided the participants with feedback and corrections for the lesson plans they prepared. The findings showed that the participants could not reflect the SOI techniques and the components of the concept and generalization in the lesson plans they prepared at the desired level. When the findings from this study were evaluated, we can state that organizing the content in lesson plans and the application of it is indeed a challenging process for student teachers. To efficiently carry out the said task, they need effective and well-structured support from teacher educators.

Published: January 2023

Despite the potential therapeutic benefits of primer vaccine dosage regimens, public perceptions of COVID-19 vaccine booster dose (VBD) acceptance and hesitancy vary among various sub-group populations. This study method designed to investigate COVID-19 vaccine booster dose acceptance and compares the multi-dimensional potential factors influencing VBD acceptance and hesitancy among university teachers and the student community in Bangladesh. This cross-sectional comparative study used a self-administered, anonymous, and validated multi-item questionnaire to rationalize the study’s outlined objectives. The questionnaire was deployed online using an online survey tool (Google forms) and conveniently sent to teachers and students in different public and private universities between 15thJune, 2022 and 15thAugust, 2022 using electronic collection methods (social media platform and emails) and following the STROBE guideline.A non-parametric data analytical tool called binary logistic regression was employed to explore the pattern of association between explanatory variables and the response variable. All the key assumptions related to binary regression analysis were examined to adjust the model suitability. Assumptions of binary logistic analysis were tested. Raw data were inserted into Microsoft Excel version 10 and imported to Statistical Package for the Social Science (SPSS) software. IBM-SPSS version 25 (RRID: SCR_016479)was used for analyzing the data. In this study analysis, p<0.05 was considered statistically significant.

Se evaluó la caída y descomposición de hojarasca de Juglans neotropica Diels (1906) (Juglandaceae) en dos unidades boscosas: bosque maduro intervenido (BMI) y bosque sucesional joven (BSJ) en la reserva natural “El Árbol de La Cheta”, Pijao (Quindío), Colombia. La caída de hojarasca se evaluó en 32 parcelas permanentes de 0,0625 m2, durante 12 meses, la descomposición se determinó con el método de bolsas de hojarasca enterradas, durante seis meses. La caída total de hojarasca en el BMI fue de 48,5 kg/ha1/año1, y para BSJ 50,9 kg/ha1/año1. La biomasa en el BMI estuvo dominada por frutos (50,3%), y la fracción foliar en el BSJ (44,5%). Finalmente no existe diferencia significativa en la caída de hojarasca entre los sitios de muestreo (U = 1.108, p > 0,05). En el proceso de descomposición, la hojarasca perdió más del 50% del peso inicial en los primeros 90 días en el BMI, y en el BSJ perdió el 46,39%. La descomposición de hojarasca se ajustó a un modelo lineal con valores promedios de k (año-1) de 1,76 en el BMI, y 1,74 en el BSJ, con una explicación del 96,34% para el BMI, y del 98,33% para el BSJ. El tiempo requerido para que se descomponga el 99% de la hojarasca es de 2,6 años para los dos sitios. La rápida pérdida de peso es consistente con la concentración de N (5,29%) y la relación C/N (8,37%) de la hojarasca.
