"Green" heavily salted split fish may be pre-cooled within a cold storage area with ice and salt, without imposing an excessive load upon storage refrigeration facilities and with little additional labour. Twelve pounds of ice plus 4 lb of salt per 100 lb of fish, uniformly applied between 3- to 4-inch thick layers of fish, will reduce the bulk fish temperature by 25°F (14 °C) in less than 8 hours.No mechanical equipment is required if flake ice be deemed a commodity. The direct cost may be estimated at less than 15 cents per 100 lb of finished (dried) fish.Pre-cooling is not essential under normal conditions but is recommended for heavily salted fish in which the degree of red bacterial contamination is unknown or suspected to be critical, and the storage refrigeration is not adequate to cool the product in a sufficiently short time.

The incipient damages of mechanical equipment excite weak impulse vibration, which is hidden, almost unobservable, in the collected signal, making fault detection and failure prevention at the inchoate stage rather challenging. Traditional feature extraction techniques, such as bandpass filtering and time-frequency analysis, are suitable for matrix processing but challenged by the higher-order data. To tackle these problems, a novel method of impulse feature extraction for vibration signals, based on sparse non-negative tensor factorization is presented in this paper. Primarily, the phase space reconstruction and the short time Fourier transform are successively employed to convert the original signal into time-frequency distributions, which are further arranged into a three-way tensor to obtain a time-frequency multi-aspect array. The tensor is decomposed by sparse non-negative tensor factorization via hierarchical alternating least squares algorithm, after which the latent components are reconstructed from the factors by the inverse short time Fourier transform and eventually help extract the impulse feature through envelope analysis. For performance verification, the experimental analysis on the bearing datasets and the swashplate piston pump has confirmed the effectiveness of the proposed method. Comparisons to the traditional methods, including maximum correlated kurtosis deconvolution, singular value decomposition, and maximum spectrum kurtosis, also suggest its better performance of feature extraction.

Plant tissue culture is a proven technique for producing banana seeds in large quantities, uniformly and in a short time to support good quality banana seeds. The banana flower meristem can be a potential explant. The banana flower meristem offers the opportunity to regenerate plants with agronomic characteristics. This study aimed to regenerate banana flowers in vitro with different sucrose and BA (Benzyladenine) concentrations after standardized surface sterilization protocols. The study used a Completely Randomized Design (CRD), two factorial designwith surface sterilents and gelling agents. The results showed that the treatmentT15 (Sodium hypochlorite (1%) + HgCl2 (0.1%)) in G1 (0.25% gelrite) recorded the lowest fungal and bacterial contamination (0.00, 0.00) & (0.73, 0.53) respectively, in in vitro cultures of male flower buds of banana cultivar KarpuraChakkarakeli (AAB). While, the combination of BA (4 mgL-1) and sucrose (30 mgL-1) concentration had directly induced organogenesis in banana male flower explants.

A general expansion of existing Cold Storage Warehousing or a program for construction of entirely new facilities calls for the proper analysis of design considerations and, most important, it requires that management properly establish the design consideration or search-out through study and professional advice, all fundamental considerations for analysis. The high cost per unit of warehouse space plus the fact that, once in use, the building and mechanical equipment cannot be readily and inexpensively repaired, changed, or added to makes careful selection and analysis of all considerations most important.

Salted fish is vulnerable to contamination by microbial. Staphylococcus epidermidis is one of the bacteria that can contaminate the salted fish. This research aims to isolate the Staphylococcus epidermidis bacteria contamination in salted white snapper fish sold in Sibolga City, North Sumatra Province. The sample used was white snapper salted fish, amounting to 10 samples from 10 traders. The isolation of Staphylococcus epidermidis was carried out using the Carter method. White snapper salted fish are mashed using a blender, then planted on Nutrient Broth (NB) as a bacterial growth media. Furthermore, identification of bacterial colonies grew using gram staining, Manitol Salt Agar (MSA) media, Blood Agar Plate (BAP) media, catalase test and confectionery media (Manitol and Glucose). The data obtained were analyzed descriptively. The results of this study suggest that Staphylococcus epidermidis contains bacterial contamination. Based on the data collected, it can be concluded that 7 out of 10 samples of white snapper salted fish sold in Sibolga City, North Sumatra Province, are contaminated with 70 percent Staphylococcus epidermidis bacteria.

The City

In tests of 40 samples of milk from the supply of the city of Edinburgh:(1) The bacterial content was, on the average, high but not abnormally so when compared with that of the milk supply of other cities. It ranged from 20,000 to 29,000,000 per c.c.(2) The results of the reductase test corresponded well with the bacterial counts and the test is recommended for obtaining a good rough idea of the bacterial numbers present, where results are required in a short time.(3) About half of the samples contained lactose-fermenting organisms in unduly high numbers; this is attributed chiefly to the lack of attention to cleanliness in production.(4) The value of the fermentation test for speedily indicating the nature of bacterial contamination is pointed out. In a general way the test corroborated the results of counts of the lactose fermenters and indicated that a number of the samples, which did not produce blown curds, contained large numbers of undesirable organisms.(5) Taken as a whole, the results seem to indicate not so much particularly high contamination as contamination of a very undesirable nature. They point to the necessity of educating the producer and distributor in the principles underlying the production of clean milk and emphasise the importance of proper control of the industry from this point of view.

The article is devoted to the problem of finding productive pedagogical and psychological techniques that help to structure a large amount of information in a short time. As a solution to this issue, it is proposed to use methods of mnemotechnics for students to master complex biological material. The paper presents the results of a study by the authors, which showed that the most difficult for students of the course of cytology are associated with a large amount of memorization units, and the most effective technique used to study this topic is the letter code.
