The aim of the present paper Was to test the value of various plant extracts (yeast barm, mature walnut embryos, coconut meal, young spinach leaves and tomato juice) used as the complementary elements of White's mineral nutrient for the culture <i>in vitro</i> of generative apices of winter wheat, rape and wetch. The results showed that the generative apices of investigated planits had various nutritive requirements which point to the necessity of a careful selection of a specific nutrient for particular plant material.

In 149 B.C. the tribune L. Calpurnius Piso proposed a law which was to have momentous consequences for the legal, political and administrative history of the Roman republic. It was his lex de rebus repetundis which first established the practice of trial before a quaestio perpetua, a jury, drawn from a panel of jurors who had always to be available, which became the standard procedure for criminal cases in the late republic. For over fifty years, from the first tribunate of C. Gracchus in 123 to the passing of the Lex Aurelia in 70, such courts were to provide a political storm-centre as various political figures attempted for their own ends to alter the criteria for the selection of the iudices who manned the juries. Moreover, from the late second century B.C. down to at least the second century A.D., the process de repetundis formed the most important means that was available to Rome's provincial subjects of bringing an action against a provincial governor for maladministration.

Impact injury to cartilage, a common consequence of joint trauma, is commonly thought to lead to degenerative osteoarthritis. Many pharmacologic agents have been developed to prevent or forestall this process. Development of a reliable model for the early stages of cartilage injury and osteoarthritis would enable the testing of novel treatments that could delay or even reverse the progression of this debilitating disease.

Studying the effect of microwave fields on the intensification of heat and moisture exchange processes in a granular layer is a rather complicated task, which cannot be effectively solved without an adequate research methodology. In presented materials, a system of principles and approaches for studying processes of microwave-convective grain treatment has been discussed. Based on the explicitly defined process target, functional-physical analysis has been performed that made it possible to specify the most essential factors of process. Morphological analysis of processes shall be performed in several stages. At each stage, targets of process have to be set by excluding combinations of factors that have no reason to be considered at this particular stage of process development. Application of mathematical simulation methods is advisable for selection of optimal options.

Sustainability of coastal areas requires the development of a standard procedure for the selection of equitable defence solutions and the design optimization of existing defences in order to minimize the impact on the environment and maximize positive effects such as species biodiversity and structure colonization. The aim of this paper is to propose a combined method, based on numerical simulations and on collection of ecological data in the field, to provide indications for an environmental friendly construction of breakwaters. This method is applied and tested against the case study of Elmer, UK, where information on existing species and their abundance related to hydrodynamic effects induced by the breakwaters

  The Ministry of Health Library is a builder library for libraries and librarians within the Ministry of Health spread throughout Indonesia. The success of the library is largely determined by the role of the librarian. Because the librarian is a profession that has a major contribution in realizing the noble ideals of the Indonesian nation in the intellectual life of the nation. Based on this, the Ministry of Health Library held a Selection of the Best Innovative Librarian. The method used in writing this scientific paper is best practice. Best Practice is an idea or new steps that make an outstanding, sustainable and innovative contribution in improving the process development and quality of education. Best Practice needs to be disseminated to others with various strategies in various places repeatedly so that it can be imitated and adopted by others. The selection of the Best Innovative Librarian was carried out in several stages. Starting from making the TOR for activities, entering activity items into the RKAKL, determining the theme of the activity, making guidelines, compiling a Committee Decree. The Best Innovative Librarian Assessment is done by looking at the completeness of documents, innovation papers and presentations. The one who gets the best score from the jury will be designated as the Best Innovative Librarian within the Ministry of Health. The Best Innovative Librarian 1 to 3 and expectations 1 to 3. The Best Innovative Librarian received awards and prizes at the Publication and Public Service Award Night of the Ministry of Health which was attended by the Minister of Health, Menpan-RB and the Head of the National Library. Librarians are the main key to the sustainability and success of a library. The selection of the Best Innovative Librarian was held as a form of appreciation and appreciation for librarians within the Ministry of Health. It is hoped that this activity can motivate librarians in the Ministry of Health to continue to work, innovate, perform and excel and have competitiveness with other professions.

AbstractA SARS-CoV-2 RBD219-N1C1 (RBD219-N1C1) recombinant protein antigen formulated on Alhydrogel® has recently been shown to elicit a robust neutralizing antibody response against SARS-CoV-2 pseudovirus in mice. The antigen has been produced under current good manufacturing practices (cGMP) and is now in clinical testing. Here, we report on process development and scale-up optimization for upstream fermentation and downstream purification of the antigen. This includes production at the 1 and 5 L scale in the yeast, Pichia pastoris, and the comparison of three different chromatographic purification methods. This culminated in the selection of a process to produce RBD219-N1C1 with a yield of >400 mg per liter of fermentation with >92% purity and >39% target product recovery after purification. In addition, we show the results from analytical studies, including SEC-HPLC, DLS, and an ACE2 receptor binding assay that were performed to characterize the purified proteins to select the best purification process. Finally, we propose an optimized upstream fermentation and downstream purification process that generates quality RBD219-N1C1 protein antigen and is fully scalable at a low cost.

With increasing need for electronic systems miniaturization to provide greater functionality in hand-held devices, through-sapphire via paves a way for the greater densification of silicon-on-sapphire devices and systems. Evaluations of two laser systems for via drilling in blank and device sapphire are outlined. Designed experiments were conducted to optimize the process and to minimize sapphire-via parasites (debris and heat-affected zone). Optical and electron microscope observations and measurements were conducted. Effects of varying via drilling techniques were evaluated for via shape and amount of parasitic effects. Laser via-drilling parameters were also evaluated for their effect on via quality. Results of the study show that acceptable through-sapphire via can be achieved and the parasites minimized with the selection of proper equipment and optimization of the drilling process.
