    AbstractTrends in the current literature emphasize the role of the organizational context in employee performance appraisal processes (e.g. Levy & Williams, 2004; Armstrong & Ward, 2005 and Murphy & DeNisi, 2008). The current study aims to develop a comprehensive research framework in order to investigate the employee performance appraisal systems and processes based on main organizational contextual dimensions, in highlighting the relevance of customization according to a company's specific organizational context. In addition, focusing on a strategic approach on human resources management, the study offers insights on the role of organizational context in developing employee performance appraisal systems that could contribute to higher performance in overall organizational strategy implementation

    Since ancient times, honey has been appreciated not only for its sensorial traits, but also for the observed effects in rejuvenation and treatment against several bad health conditions, when used externally or internally, along with other beehive products, such as pollen, propolis and royal jelly. Today, it is known that such effects are generated by compounds bearing antimicrobial, anti-inflammatory, and antioxidative features (enzymes, polyphenolic molecules). The purpose of this study was to assess the total phenolic and flavonoid contents of 28 samples of Romanian raw monofloral honey (acacia; linden; rapeseed, sunflower and mint), and to establish their correlations with several qualitative parameters. Pearson’s test revealed a strong positive correlation between total phenolic content and total flavonoids (r = 0.76) and color intensity (r = 0.72). For total flavonoid content, correlations were strongly positive with color intensity (r = 0.81), ash content (r = 0.76) and electrical conductivity (r = 0.73). The relevant levels of polyphenols and flavonoids identified in the analyzed honey types demonstrate its antioxidant potential, with essential nutritional and sanogenic features in human nutrition

    Romania is known among the main European honey producers, due to the variety of landforms as well as the diversity of the flora. Thirty-four honey samples of the acacia, linden and multifloral types, produced in eastern Romania and collected during 2013–2018, were physico chemically analyzed using methods provided by the national and EU standards. The results of water-insoluble solids, color and refractive index were found to be 0.023–0.131%, 0.3–76.4 mm Pfund and 1.485–1.499, respectively. The moisture content ranged between 15.20% and 20.77%, solid substances content ranged between 79.23% and 84.80% and total soluble substances content ranged between 77.83 ◦Brix and 83.26 ◦Brix. The obtained values of specific gravity were from 1.414 to 1.450 g/cm3 , pH ranged from 3.673 to 5.503 and free acidity ranged between 2.4 meq and 50 meq kg−1 . The ash content and the electrical conductivity varied between 0.030 and 0.543% and 130 and 679 µS cm−1 , respectively. Pearson0 s correlation analysis showed an intense association of the ash content with electrical conductivity (r = 0.81). Our findings reveal the qualitative level of Romanian honey and the variation in quality parameters due to factors such as geographical region, climatic conditions, botanical origin and handling or storage conditions

    University of Medicine and Pharmacy of Targu Mures, Romania, University Hospital of Parma, ItalyIntroduction. Sentinel lymph node (SLN) is defined as the first lymph node localized on the direct lymphatic drainage pathway from a primary tumor. The sentinel lymph node biopsy (SLNB) is largely used in breast cancer and melanoma but it may also be useful in other epithelial skin cancers as well as in tumors located in the upper or lower gastrointestinal tract, lungs, thyroid, cervix and vulva. SLNB in melanoma is essential for an accurate staging, to estimate the risk of extension to other lymph nodes or organs and to evaluate the prognosis. Melanoma, even if it is not as common as the basal cell carcinoma or squamous cell carcinoma among the skin tumors, presents an increasing incidence and a higher mortality

    Catedra Boli infecţioase, tropicale şi parazitologie medicală USMF „N.Testemiţanu”, Spitalul Clinic de Boli infecţioase „T.Ciorbă”Out of 40 patient with mumps meningitis admitted to the T.Ciorba Clinical Hospital of the Infectious Diseases between November 2007-February 2008 most frequently were affected the men (98%), their age being between 14-29 years old, presented by students pupils. Meningitis, as a rule, appeared at the 6-9 day. The combinated form (parotiditis +orhitis +pancreatitis + meningitis) has been revealed in 72% of cases. Meningitis symptoms have been diagnosed in 58% of cases. The lumbar punction has revealed hypertensive transparent liquor, limphocitozis and insignificant modifications of the glucose and chloride levels. Au fost examinaţi 40 de bolnavi cu oreion la care s-a dezvoltat tabloul clinic de meningită urliană, spitalizaţi în SCBI ”T. Ciorbă” pe parcursul a 4 luni (noembrie 2007 – februarie 2008). Vîrsta pacienţilor a variat între 14 – 29 ani, majoritatea fiind elevi şi studenţi din diferite colectivităţi, printre care predominau bărbaţi (98%). Meningita s-a declanşat, de regulă, la a 6-9 zi de boală. La majoritatea (72%) pacienţilor s-a stabilit forma combinată a maladiei (oreion + meningită + pancreatită +orhită). Semnele meningiene s-au depistat la doar 25 (58%) pacienţi. LCR s-a caracterizat printr-o pleiocitoză limfocitară şi modificări neesenţiale a glucozei şi hlorizilor

    During biodiesel production, massive amounts of raw glycerol are created generating an environmental issue and the same time an increase of biodiesel production cost at the same time. This raw glycerol could be converted by specific strains into value-added products, like 1,3-propanediol (1,3-PD), an important monomer used in the synthesis of biodegradable polyesters.The present work is based on recent scientific articles and experimental studies on the targeted topic, namely on the use of bacterial strains for bioconversion of biodiesel-derived glycerol into valuable products, like 1,3-PD. Concentrations, yields and productivity of 1,3-PD are presented for various bacterial strains. Important results as respects the microbial bioconversion of biodiesel-derived glycerol into 1,3-PD were registered for strains like Klebsiella pneumoniae, Citrobacter freundii, Escherichia coli and Lactobacillus diolivorans.From this study can be concluded that waste glycerol may be used as a nutrient source for microbial development and the production of 1,3-propanediol with high concentrations and yields
