Experimental Preparation

Cheesemaking is one of the most complex technologies in dairy and cheese science as a product of this art enjoys a special status among dairy products thanks to its high-value ingredients. Facts about rich cheese culture and tradition affect the modern consumer society, occupied by brands and consumers, as a result, are no longer satisfied only with good products. Thus, cheese is ideal product for modern consumers. Upon this the idea of joining cheese and traditional Bosnian product - the prune was born. In this research the experimental preparation of thermally - acidic coagulating cheese with the addition of prune is presented with the assumption that this cheese is acceptable for consumers. The cheese was tested for chemical composition and the quality parameters and it is shown that the quality parameter values correspond to heat-acid coagulating cheese type. In order to examine the shelf life of the product cheese was stored for 5 and 10 days and the changes of that samples occurred were noted. As a fundamental part of the research to determine the acceptability of the product sensory analysis was performed and the research showed that the experimental product was 95% acceptable by consumers and 100% acceptable by panel of expert evaluators. The cheese cannot be stored for a long time and it is proper to be consumed in a fresh state.

Reference Tool

A new method for automatic voice-quality registration is presented. The method is based on a technique called phonetography, which is the registration of the dynamic range of a voice as a function of fundamental frequency. In the new phonetogram-recording method fundamental frequency (F 0 ) and sound-pressure level (SPL) are automatically measured and represented in an XY-diagram. Three additional acoustical voice-quality parameters are measured simultaneously with F 0 and SPL: (a) jitter in the F 0 as a measure for roughness, (b) the SPL difference between the 0–1.5 kHz and the 1.5–5 kHz bands as a measure for sharpness, and (c) the vocal-noise level above 5 kHz as a measure for breathiness. With this method, the voice-quality parameter values, which may change substantially as a function of F 0 and SPL, are pinned to a reference position in the patient's total vocal range. Seen as a reference tool, the phonetogram opens the possibility for a more meaningful comparison of voice-quality data. Some examples, demonstrating the dependence of the chosen quality parameters on F 0 and SPL are given.

The correlation between the service characteristics of the working surfaces of car parts belonging to the rotary body class, and quality parameters—in particular, the height-related roughness parameter Ra—was estimated. Low values of Ra were found to be unable to guarantee an optimal microrelief geometry and, accordingly, high-performance characteristics of the working surface. The oil-accumulation power of the parts was investigated as a primary characteristic of sliding friction using the group of Rk parameters in the Abbott–Firestone diagram, based on the profilogram of the test specimen’s surfaces. The oil-absorption power of the surfaces formed by different technological operations was compared with different microgeometric quality parameter values.

Mangrove is one of the coastal ecosystem is able to grow in fluctuating water conditions. Mangrove areas are found on the Nusa Lembongan island, Bali, is a ??mangrove ecosystem that have the unique characteristics of water area. The mangrove area is located on one of the small islands in Bali that have no source of freshwater input and there is the entrance of water into the mangrove forest. The uniqueness of waters in mangrove ecosystem will affect the type and density of fauna associated, particularly mollusca. Mollusca are one of the animals that live and thrive in the mangrove ecosystem. Therefore, it is necessary to study which aimed to provide a description of the water quality and mollusca on mangrove ecosystem in Nusa Lembongan. This research was conducted in June 2015 on a six station observation. Measurement of water quality conducted on four water parameters such as temperature, DO, pH, and salinity. Observation on the type and density of mollusca done using transects squared (1 x 1 meter). The range of values ??obtained water quality parameters, such as; 1) salinity (32.00-34.33 ppm), 2) pH (7.06-7.96), 3) temperature (27.27-30.13 Celsius), and 4) DO (2.60-6.90 mg/l). Water quality parameter values ??obtained are still in the range of water quality standard and suitable place to live and grow for marine biota life. Dissolved oxygen (DO) value was still below the threshold quality standard. There six families of mollusca found in six observation station, such as Neritidae, Littorinidae, Columbellidae, Olividae, Carditidae, Muricidae, Potamidae, Certthiidae. The highest density was in Family Potamidae (1.83 ind/m2), so the Family Potamidae is able to adapt and have a wide area deployment.

Nine runoff containment basins (RCBs), used directly or indirectly for irrigating plants in ornamental plant nurseries, and one adjacent stream were sampled for water quality between Feb. and July 2013 in Maryland (MD), Mississippi (MS), and Virginia (VA). Triplicate water samples were taken monthly. Analysis was done for 18 water quality variables including nitrate-nitrogen (NO3−-N) and ammonium-nitrogen (NH4+-N), orthophosphate-phosphorus (PO4-P) and total-phosphorus (T-P), potassium, calcium, magnesium, sulfur, aluminum, boron (B), copper (Cu), iron (Fe), manganese, zinc (Zn), pH, total alkalinity (T-Alk), electrical conductivity (EC), and sodium. Additionally, 15 RCBs from 10 nurseries in Alabama (AL), Louisiana (LA), and MS were sampled in 2014 and 2016. Most prevalent correlations (P = 0.01) were between macronutrients, EC, B, Fe, and Zn, but none were prevalent across a majority of RCBs. Water quality parameter values were mostly present at low to preferred levels in all 25 waterways. Macronutrient levels were highest for a RCB that receives fertility from fertigation derived runoff. Water pH ranged from acidic to alkaline (>8). Results of this study show water quality in RCBs can be suitable for promoting plant health in ornamental plant nurseries, but also shows levels will vary between individual RCBs, therefore demonstrates need to verify water quality from individual water sources.

Given their beneficial effects in terms of health, the natural products, especially beehive products, have drawn the attention of consumers since long time ago. In order to guarantee the quality of these products on the market, their chemical composition needs to be analyzed. Thus, this current research had as objective the establishment of quality parameters for beehive brood food derived products: apilarnil and queen bee larvae triturate. These two products were compared with royal jelly which is the basis of brood food in the first 3 days of larval stage. The carbohydrates were determined by HPLC-IR and allowed the identification of seven carbohydrate compounds, predominantly glucose, fructose and sucrose. The lipid profile was analyzed by the Soxhlet method. The total protein content was determined by the Kjeldahl method. Free amino acids were analyzed by LC-MS. A total of 31 amino acids were identified of which nine are essential amino acids for humans.

The experiment was conducted in a well-known private livestock research and development farm in Bangladesh to find out the variation of semen quality parameter among three generations (F1, F2 and F3) of Holstein Friesian upgraded breeding bulls. A total of 312 ejaculates were collected from 6 upgraded breeding bullsthrought the experimental year. The recorded data were summarized using Microsoft Excel 2010 and analyzed using GraphPad Prism 5 softwere. Out of the 312 ejaculates, 273 (87.50%) were found to be creamy in color followed by 26 (8.33%) and 13 (4.17%) as yellowish and watery, respectively. Generation had significant (P<0.05) effect on ejaculate volume, consistancy, mass activity, sperm concentration, initial and post freezing motility. The highest (7.389±0.19ml) and the lowest (5.156±0.13ml) volume of semen were found in third (F3) and first generation (F1), respectively. The mass activity ranges from 3.74±0.04 to 4.30±0.05. Sperm concentration and pH varied insignificantly (p>0.05) but initial motility and post freezing motility had the significant differences among the three generations. Initial motility ranges from 75.87±0.32 to 78.40±0.38 percent and the post freezing motility ranges from 50.38±0.41 to 52.16±0.43 percent. It could be concluded that most of the semen quality parameters were influenced by generation and freezing. Semen characteristics were better in F2 followed by F3 and F1 generation in upgraded Holstein Friesian bulls. Res. Agric., Livest. Fish.7(3): 457-463,  December 2020
