Association between metabolic and immunological changes during the transition period of dual-purpose cows in the Veracruz tropic, Mexico
(2023-12-30)
The objective of this study was to identify changes and associations in body condition score (BCS), serum glucose and β-hydroxybutyrate (BHB) concentrations, and white blood cell populations in dual-purpose cows during the transition period in the Veracruz tropic. BCS was evaluated and blood samples were taken weekly to determine white blood cell populations, serum glucose and BHB concentrations of 30 multiparous dual-cows (Bos taurus × Bos indicus) from 3 weeks before the expected date of calving to 3 weeks postpartum. ...

Schlussbericht zum Projekt dataject.log
(2023)
Die termingerechte Fertigstellung, Lieferung und Inbetriebnahme einer Maschine oder Anlage sind entscheidende Wettbewerbsfaktoren für die zumeist mittelständischen Unternehmen des Maschinen- und Anlagenbaus. Zudem wird die geforderte Individualisierung der Produkte zu einem wichtigen Wettbewerbsmaßstab. In diesem Zusammenhang bestimmen die präzise Planung und Durchführung aller logistischen Prozesse rund um ein kundenspezifisches Projekt die zuverlässige Terminplanung und -einhaltung. Diese Prozesse sind allerdings ...

Modeling analysis of 21st century climate change projections and their impacts on the hydrology of the Karaj-Jajrood basin, Iran
(2023-12)
Two main rivers, Karaj and Jajrood which provide metropolitan Tehrans’ water, flow in Alborz and Tehran province, respectively. In the last decades, the impact of climate change on temperature and precipitation is tangible in these two provinces. For the Karaj-Jajrood basin, during the period 2003-2012, the minimum temperature increased by 1°C, the maximum temperature by 0.6°C and precipitation decreased by -7%, relative to the average of 1972-2012.
To assess climate change impacts in the region, the Statistical ...

Determination of consumer milk price in the informal dairy market in Bangladesh: A district level analysis of vertical system linkage
(2023-12-30)
The objective of this study was to identify the determinants of consumer milk prices and test the hypothesis that input prices, e.g., rice straw and wheat bran, as well as the farmgate milk price exert an influence on the consumer milk price. A unique panel dataset from July 2018 to June 2021 was obtained from the Integrated Dairy Research Network (IDRN) Bangladesh Monthly Dairy Sector database and was analysed using the Generalized Methods of Moments (GMM) methodology. The data collection and validation were done ...

On the Effect of Quenching on Postweld Heat Treatment of Friction-Stir-Welded Aluminum 7075 Alloy
(2019)
This work focuses on the effect of postweld heat treatment (PWHT) on the mechanical properties and microstructural evolution of aluminum 7075 alloy processed via friction stir welding (FSW). FSW is known to be capable of grain refinement in the nugget zone (NZ). Two different quench media (water and air) were employed for PWHT. Regardless of the quench media, the PWHT led to the occurrence of grain growth in the NZ of the FSWed aluminum 7075 alloy. Abnormal grain growth occurred in the water quenched specimen. It is ...

On the Friction Stir Processing of Additive-Manufactured 316L Stainless Steel
(2022)
The novel combination of friction stir processing (FSP) and additive manufacturing (AM) is studied herein. Laser-based powder bed fusion of metals (PBF-LB/M) is used to establish 316 L stainless steel with a bimodal microstructure. Upon FSP, the as-built bimodal microstructure with an average grain size of 179 μm is transformed into the unimodal microstructure containing ultrafine grains with an average grain size of 1.2 μm. Results obtained by mechanical testing reveal that after FSP; the hardness, the yield point, ...

Cyclic Deformation Response of Ultra-fine Grained Titanium at Elevated Temperatures
(2019)
This study focuses on the high-temperature cyclic deformation response (CDR) of ultra-fine grained (UFG) titanium of commercial purity (grade 4) processed via equal channel angular extrusion as a severe plastic deformation method. Low-cycle fatigue experiments were conducted at elevated temperatures up to 600 °C and at strain amplitudes ranging from 0.2% to 0.6%. Besides temperature and strain amplitude, the influence of two processing routes (8BC and 8E) on the fatigue characteristics of UFG Ti was examined. It is ...

Effect of different levels of fluted pumpkin leaf (Telfairia occidentalis) in grower rabbit diets: Assessing growth parameters, haematological profiles, and serological responses
(2023-12-31)
The effect of fluted pumpkin leaf (FPL) on the growth performance, haematology, and serology of growing rabbits were examined. Seventy-five weaned rabbits of Dutch breed, with a mean weight of 513 g, and different sexes were allotted into 5 treatments with 3 replicates and each replicate housing five weaned rabbits. The five treatment diets were formulated to contain FPL at inclusion levels of 0 % (control), 30 %, 50 %, 70 % and 100 % in a completely randomized design. The animals were fed twice daily and given water ...

ORDEN ENCRIPTADO
(2022-12-09)
Los monasterios femeninos fueron un equipamiento imprescindible dentro del panorama urbano y arquitectónico de las ciudades virreinales. Constituyeron además auténticas unidades urbanas con autonomía y complejidad propia. La presente conferencia visibiliza el orden urbano generativo y esboza las características fundantes de la espectacular arquitectura de uno de los monasterios más importantes de Latinoamérica: el Monasterio de Santa Catalina de Siena de Arequipa. /Gonzalo Ríos Vizcarra Arquitecto por la Universidad ...

Delaying Ripening of Cantaloupe fruits by Various Treatments During Storage
(2023-12-28)
This study was conducted for two seasons 2021 and 2022 to investigate the influence of Putrescine (PUT) at 0.1 or 0.2% and Spermine (SPM) at 0.1 or 0.2% and Chitosan (CS) at 1000 or 2000 ppm and in addition untreated control on quality attributes and delaying ripening of cantaloupe fruits (cv. Primal) during storage at 5º C for 28 days. The results indicated that all treatments were effective in reduced weight loss and color changes and maintained, fruit firmness, TSS, sugar content, total carotenoids and overall ...
