Authors: Kuruvadi Sathyanarayanaiah , Zúñiga Enríquez Juan Carlos 
Published: December 2023

Se evaluaron 9 y 14 genotipos de cebada de dos y seis hileras respectivamente, bajo un diseño de bloques al azar con cuatro repeticiones, con objeto de comparar las características cuantitativas entre dos especies, identificar líneas con altos rendimientos, estudiar parámetros genéticos y correlaciones para diferentes características agronómicas.
El análisis de varianza indicó diferencias significativas para rendimiento, granos/espiga, peso de grano, longitud de espiga, altura de planta, días a madurez fisiológica y peso hectolitrico, individualmente, en los genotipos de dos y seis hileras, y además en el análisis combinado revelaron variabilidad considerable para estas características en los genotipos incluidos. En esta investigación, se identificaron como sobresalientes para rendimiento los genotipos: Dram, Antártica 04 y ND4994.16 en cebadas de dos hileras, y Robust, Cerro Prieto y Gloria "S"/Come"S" CMB 81-294-6B-2Y8m-OY en cebadas de 6 hileras; estas últimas, mostraron una ligera ventaja en rendimiento en comparación con las primeras.
Para los caracteres granos/espiga y peso de grano, los tipos de seis hileras manifestaron 82.05 por ciento y 4.13 por ciento más que las líneas de dos hileras, mientras que éstas superaron en 35.85 por ciento y 3.78 por ciento para longitud de espiga y peso hectolitrico, respectivamente.
Los genotipos Robust, Gloria "S"/Come"S" CMB 81-294-5B-5Y-1M-1Y-OM y Trompillo, fueron los mejores para granos/espiga. Para peso de grano, las me- jores líneas fueron: Robust, Karan 15 y Cerro Prieto. En longitud de espiga des- tacaron Antártica 04, Cerise y Dram. La heredabilidad en sentido amplio presentó valores altos (80 a 98%) para todas las características estudiadas. Se en- contraron correlaciones positivas y significativas entre rendimiento con días a madurez fisiológica y peso hectolitrico.

Se llevó a cabo un experimento en dos etapas: I. Estimación de la energía metabolizable (EM) de la harina de zanahoria (HZ); II. Prueba de alimentación con pollas de engorda de la línea comercial Indian River de 1-53 días de edad. La estimación de la EM se llevó a cabo mediante la técnica propuesta por Sibbald (1963) y el valor encontrado de EM de la HZ fue de 2532 kcal/kg. Así mismo, la digestibilidad aparente de la HZ fue de 71.14 %.
En la prueba de alimentación se utilizaron dietas conteniendo 0, 9, 18, 27 y 36 % de HZ con dietas isoprotéicas (22 % para iniciación y 20 % de PC para finalización) con diferentes niveles de EM (3000, 2950, 2900, 2850 y 2800) y (3,100, 3000, 2900, 2800 y 2700 kcal/kg) para iniciación y finalización respectivamente. Los consumos de alimento, peso corporal y conversión alimenticia fueron: (1.532, 1.425, 1.366, 1.338 y 1.260 kg); (0.804, 0.783, 0.675, 0.632 y 0.526 kg) y (1.67, 1.81 2.02, 2.11 y 2.39) para iniciación; (3.005, 3.207, 3.158, 3.153 y 3.021 kg), (1.285, 1.249, 1.146, 1.057 y 1.017 kg) y (2.33, 2.56, 2.75, 2.99 y 2.96) para finalización; y al evaluar de 1-53 días de edad los resultados fueron los siguientes: (4.358, 4.509, 4.525, 4.492 y 4.281 kg); (2.090, 2.032, 1.822, 1.690 y 1.544 kg) y (2.08, 2.21, 2.48, 2.65 y 2.76). En los períodos de iniciación, finalización e iniciación-finalización no hubo diferencia significativa (P≥.05) para consumo de alimento, y hubo diferencia significativa (P≤.05) para peso corporal y conversión alimenticia. Las ecuaciones de tendencia a respuesta nos indican que podemos incluir un 22,23 y 18 % de HZ en dietas para los períodos respectivos.

En áreas aledañas a la Universidad Autónoma Agraria Antonio Narro, en la localidad El Álamo, se establecieron algunos viñedos en los años 1950 a 1960; los cuales desaparecieron en su totalidad debido a problemas basados en una inadecuada selección de variedades, así como a la incidencia de plagas como filoxera (Phylloxera vastatrix), barrenador de la madera (Amphicerus bicaudatus Say). Y algunas enfermedades del tipo viral (Yellow mosaic y fan leaf). En la actualidad, y con el objetivo de reiniciar una viticultura más prometedora que permita utilizar materiales más adecuados y que produzcan uvas de mejor calidad para el consumo en fresco, se realizó en la UAAAN, un estudio de adaptación de 50 cultivares de mesa y pasa, cuyos materiales fueron conducidos bajo el sistema de cordón bilateral, con un diseño completamente al azar con 17 tratamientos, tres repeticiones y nueve plantas por variedad.
Los resultados, en cinco años de estudio, revelan que dentro de las variedades para el consumo en fresco (mesa) que más se han adaptado son: Black Rose, Barlinka, Exotic y Rosa del Perú.
El Sistema de los derechos públicos subjetivos de Georg Jellinek: Impacto y actualidad en el Derecho administrativo
Authors: Vergara Blanco Alejandro 
Published: December 2023

Georg Jellinek (1851-1911) es reconocido por su teoría acerca del “Sistema de los derechos públicos subjetivos”, a partir de la cual el individuo solo por el hecho de pertenecer a un Estado es titular de derechos púbicos subjetivos.Si bien esta idea fue controversial, provocando la crítica de autores contemporáneos alemanes y extranjeros, en la actualidad se ha destacado su aporte dentro del derecho constitucional y administrativo, consagrándose tanto judicialmente como legalmente. Así, el fenómeno de la subjetivización del derecho administrativo se basa en la posibilidad que tiene el ciudadanode exigir el resguardo de sus derechos dentro del contencioso administrativo.

La obra de la autora Setuáin sobre reutilización de agua, resulta ser un texto actual, novedoso y muy necesario para comprender el fenómeno del reúso de las aguas en España, dentro del contexto de la Unión Europea. También constituyeun aporte muy valioso para estudiar este fenómeno desde la perspectiva chilena puesto que, adelanta al jurista la configuración de instituciones que apenas se han recogido en el Derecho nacional, por no decir que solo se han esbozado como meras pretensiones en la legislación de aguas y de cambio climático. Es, además, un trabajo que resulta de necesarialectura puesto que el mismo fenómeno de la crisis climática que azota en otras latitudes, está presente en nuestro territorioy el Poder Legislativo está haciendo innumerables esfuerzos por regular la reutilización de las aguas residuales.

Microencapsulated propolis in chewing gum production
Authors: Bostancı Emre , Gölge Evren 
Published: December 2023

Propolis is a resin with high antibacterial and antioxidant properties that honey bees (Apis mellifera L.) gather and then harmonize through their metabolic secretions. Propolis is beneficial to dental health because it contains antibacterial activity against the Streptococcus mutans, which causes tooth decay. The aim of this study is to use microencapculated propolis extract (MPE) in chewing gum formulation for the first time, in order to protect propolis from environmental effects during production and to ensure controlled release in mouth. Spray drying method was applied where maltodextrin acted as coating material. The particle structure of MPE was investigated by scanning electron microscope. The encapsulation efficiency was determined as 62.19%. The hygroscopicity and moisture content of the MPE particles was found as 31.50% and 7.98% respectively. The DPPH scavenging ability, total flavonoid and total phenolic content of the MPE appeared lower than propolis extract. The total flavonoid content of MPE was calculated as 29.06 mg/kg and total phenolic content as 89.17 mg/kg. In vitro antimicrobial activity against Streptococcus mutans of 9% MPE containing gum samples was measured highest with 4.20 mm zone diameter. Hunter b* value increased with increasing MPE concentration. The final MPE incorporated chewing gum appear to be highly functional.

Optimization of culture conditions for and assessment of kimchi-originated lactic acid bacterial isolates toward their extracellular GABA-producing ability
Authors: Lee Jin-Sung , Kim Keun-Sung 
Published: December 2023

The objectives of this study were to optimize the medium and culture conditions using a strong γ-aminobutyric acid (GABA) producer as a reference lactic acid bacterial strain, to screen and identify GABA-producing lactic acid bacterial isolates from kimchi, and to determine their extracellular GABA-producing abilities. Thin-layer chromatography was used to screen GABA-producing bacterial isolates and high-performance liquid chromatography was used to evaluate the bacterial GABA production abilities. Species-specific polymerase chain reaction analyses were used to identify GABA-producing bacterial isolates. The optimal medium and culture conditions were found to be the modified Man–Rogosa–Sharpe (MRS) broth (with an initial pH of 6.5) containing 4% sucrose, 5% glutamate, and 1% yeast extract at 37°C for 5 days. After incubation under the optimized culture conditions, 217 kimchi bacterial isolates were screened to evaluate their respective GABA-producing abilities. Screening the 217 kimchi bacterial isolates identified 24 GABA-producing lactic acid bacterial isolates (11%): Lactobacillus plantarum (17), Lactobacillus brevis (six), and Leuconostoc mesenteroides (one), indicating that only a small proportion of the strains produce GABA in the culture broth. The extracellular GABA-producing abilities of the bacterial strains identified in this study varied even within the same species, ranging from 5.8 to 101.7 mM among the 17 GABA-producing L. plantarum isolates and from 8.5 to 88.6 mM among the six GABA-producing L. brevis isolates. In summary, three species of the 24 kimchi GABA-producing bacterial isolates were identified, including one rare species (L. mesenteroides) and the two most dominant species (L. brevis and L. plantarum).

Authors: Dinçoğlu Ahmet Hulusi , Ileri Ali , Rugji Jerina 
Published: December 2023

The focus of the present study was to evaluate the bioactive properties of Capparis spinosa (caper) fruits and to investigate some quality parameters of Tulum cheese with addition of caper. Analyses for the phytochemical components of caper fruit used in the production of Tulum cheese showed that it has high levels of bioactive components in terms of antioxidant activity, total phenolics, and flavonoids. It was determined that C. spinosa, which is used in the production of Tulum cheese, had a good radical scavenging activity (DPPH radical assay). Four experimental groups were arranged in the present study and analyzed on the 1, 30, 45, 60, and 90th day of ripening. T_C was designed as the control group, T_C1, T_C2, and T_C4 groups contained 1, 2, and 4% of caper. According to the obtained results as the content of caper increased, dry matter ratios, ash, pH values, tyrosine and free fatty acid values in cheese increased significantly. The microbiological evaluation revealed that the caper affected positively Lactobacillus spp. counts. The highest aroma and taste scores among caper cheeses were given to the control group (T_C). Generally, caper did not have a negative effect on the textural profile of the product. These results revealed that C. spinosa contributes to the improvement of the bioactive potential as well as increasing the quality parameters of cheese.

Published: December 2023

Fermentation factors in the making of modified plantain flour must be optimized to obtain optimum conditions that produce the desired characteristics of flour/starch. In this research, we used mix-cultured lactic acid bacteria (LAB) and yeast for plantain fermentation. Response Surface Methodology (RSM) was used to explain the quantitative relationship between input and response variables. The design used is Combine D-optimal. The quantitative independent variables (X) selected were A = culture concentration (lower limit 2%; upper limit 6%) and B = fermentation time (lower limit 8 hours; upper limit 24 hours). Descriptive variables were C = type of plantain (C1 = “tanduk” plantain; C2 = “nangka” plantain) and D = type of culture (D1 = SC; D2 = LAB1 + LAB2; D3 = LAB1 + LAB3; D4 = LAB2 + LAB3; D5 = LAB1 + LAB1 + SC; D6 = LAB1 + LAB3 + SC; D7 = LAB2 + LAB3 + SC). Parameters of flour characteristic analyzed or response (Y) were carboxyl number (Y1), total acid (Y2), swelling number (Y3), pH (Y4), paste clarity (Y5), gelatinization properties: peak (Y6); trough 1 (Y7); breakdown (Y8); final viscosity (Y9); setback(Y10); peak time (Y11); pasting temperature (Y12), water content (Y13), color : *L (Y14); *a(Y15); *b (Y16) and c (Y17). The result showed that a combination of 6% culture concentration and 12.62 hours of fermentation time with a desirability value of 0.66 was the optimum condition with carboxyl value 0.15, total acid 0.47, swelling rate 13.49, peak time 5397.02, breakdown 2259.22, final viscosity 4125.22, setback 98.99, and dL 65.59.

Objective. To determine whether Lentinula edodes (L edodes) cultured on eucalyptus chips in the Ecuadorian highland generates antioxidant metabolites and anti-inflammatory effects.
Methods. Total phenolic content was determined by the Folin-Ciocalteu reaction, the in vitro antioxidant activity of L edodes extracts was evaluated by the DPPH method and the in vivo anti-inflammatory activity was studied in mice. The chemical composition was studied by phytochemical screening and gas chromatography/mass spectrometry (GC/MS).
Results. Total phenols were higher in extracts with increasingly high-water content. The antioxidant activity was robust and significantly strong in these extracts, suggesting the active metabolites are water-soluble. The anti-inflammation activity was significant in aqueous extracts only. Phytochemical screening indicated an overall similar composition to the literature reported earlier. GC/MS detected galactitol, trehalose, xylitol, phosphoric acid and octadecanoic acid among the most abundant metabolites.
Conclusions. Cultivation on eucalyptus biomass at the Ecuadorian highlands retains the overall chemical composition, the phenolic content, antioxidant levels, and the in vivo anti-inflammatory activity of L edodes. The 11.3% content of trehalose observed is interesting for its capacity to control cellular stress damage.

Published: December 2023

Plectranthus amboinicus (Lour.) Spreng is a type of Lamiaceae perennial herb that is widely used in folk treatments for respiratory and skin diseases. Notably, research on the hypouricemic effect of P. amboinicus is limited. This study investigated the uric acid–reducing efficacy of P. amboinicus in mice with potassium oxonate-induced hyperuricemia by performing an in vitro xanthine-oxidase-inhibition-activity-guided test of P. amboinicus extract (PAE) and its fractions. The ethyl acetate fraction (EAF) of PAE exhibited optimal efficacy in terms of the phenolic content, DPPH scavenging activity, and xanthine oxidase inhibition. We further demonstrated the uric acid–reducing activity of EAF in a mouse model of potassium bromate–induced hyperuricemia. The results can serve as a useful preclinical reference for researching the gout prevention effects of functional foods.

Authors: Syam Tri Sutriani , Kadir Syahrijuita , Yustisia Ika 
Published: December 2023

Durian seeds are a waste product from durian fruit. Durian seeds are often used by people as the main ingredient in making bread and cakes. However, the use of durian seeds as the main ingredient in making nata has never been done. Nata is extracellular cellulose obtained from the activity of the bacteria Acetobacter xylinum. The nata that is often found is nata de coco made from coconut water as the main ingredient. This research aims to look at the formation of nata de durio from durian seeds.
The results showed that different dry weights of durian seeds did not affect the thickness of the Nata De Durio formed. The thickness of Nata De Durio on days 7 and 14 was highest at a dry weight of 250 grams of durian seeds with an average of 0.4 and 0.5 cm and the lowest was at a dry weight of 100 grams of durian seeds with an average of 0. 3 and 04 cm.
Conclusion: The difference in dry weight of durian seeds does not affect the thickness of Nata De Durio. However, the dry weight of 250 gram durian seeds has a better Nata De Durio thickness compared to the dry weight of 100 grams and 200 grams of durian seeds.

Published: December 2023

The purpose of this study was to investigate the impact of marine algal extract as foliar spray on growth, physiological, mineral composition, different osmoprotectant levels, various parts of antioxidant system, and gene expression of greenhouse lettuce (Lactuca sativa L.) plants grown under saline conditions (50mM and 100mM). Through LC/MS analysis, the algal extract's phenolic composition was determined by its abundance in quinic acid, gallic acid, kaempferol and luteolin. The concentration of leaf proline increased while the biomass production, chlorophyll fluorescence, SPAD index and mineral composition all decreased as a result of salt stress. The salt-stress tolerance mechanism in lettuce involved the expression of genes that encode antioxidant enzymes, including LsSOD, LsCAT, and LsAPX, in both stressed and control plants, which demonstrates their important roles. The findings revealed that plants that were treated with marine algal extract had a greater ability to handle salt challenge, as evidenced by a significant (p < 0.05) increase in plant growth, SPAD index, Fv/Fm ratio, a better nutritional status in addinto a better osmoprotection against salt stress. Malondialdehyde level, Hydrogen peroxide and stability index levels were significantly decreased. Furthermore, the antioxidant system saw a significant improvement, as demonstrated by the increased activity of catalase (CAT), superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) under moderate stress conditions (50mM) and more abundant LsCAT transcripts in the stressed plants. Overall, our findings indicate that marine algal extract appears to be an effective biostimulant product for treating lettuce under saline conditions.

Authors: Mahmoudabadi Parvin , Naderi Akhormeh Alireza 
Published: December 2023

SummaryThis paper studies the issue of Robust Fuzzy Model Predictive Control (RFMPC) of nonlinear discrete‐time systems in the presence of disturbance. To this end, Takagi‐Sugeno (T‐S) fuzzy model is adopted in order to characterize uncertain nonlinear systems and facilitate providing controller for such systems. Non‐parallel distributed compensation (non‐PDC) technique is applied to design improved RFPMC with better performance. The optimization problem of RFMPC is represented in terms of linear matrix inequalities (LMIs) so as to decrease online computational burden. Besides, feasibility and stability which are decisive factors in MPC theory are investigated for the proposed method. Ultimately, two examples including cart‐damper‐spring system are simulated to evaluate the results of this research work.
