Three studies investigated the relationships among employees' perception of supervisor support (PSS), perceived organizational support (POS), and employee turnover. Study 1 found, with 314 employees drawn from a variety of organizations, that PSS was positively related to temporal change in POS, suggesting that PSS leads to POS. Study 2 established, with 300 retail sales employees, that the PSS...
Mutants of Escherichia coli K12, defective in phosphatidylserine synthetase (pss), can be isolated as temperature-sensitive, conditional lethals. When cultivated at intermediate temperatures (30 degrees), such mutants contain approximately 3 times more phosphatidylglycerol plus cardiolipin (and less phosphatidylethanolamine) than normal. We now wish to report that, under these conditions, the p...
Coordinated Control of SVC and PSS for Transient Stability Enhancement of Multi-Machine Power System
The coordinated control for SVC and generic/multi-band PSS for power swing damping is presented for the multimachine power system. The background and the mathematical models of the generic PSS, the multi-band PSS and the SVC are presented. The V-I characteristics as well as the dynamic properties of the static var compensator (SVC) are presented. The multi-machine power system is simulated usin...
Background Primary Sjögren’s Syndrome (pSS) is a chronic autoimmune syndrome characterised by sicca symptoms, fatigue, musculoskeletal pain and an increased risk of lymphoma. Patient populations are notably heterogeneous in their symptoms, adding to the challenge of pSS research. This study utilises serum samples from the UK Primary Sjögren’s Syndrome Registry (UKPSSR) a large cohort of clinica...
Prostatic stromal sarcoma (PSS) is a rare tumor that normally occurs in adult age. Its management relies mainly on surgery. We report the first case of PSS occurring in an adolescent. There was evidence of a good response to chemotherapy including ifosfamide, doxorubicin, vincristine and actinomycin-D, although the final outcome was dismal. A review of the English literature revealed 14 additio...
Primary Sjögren's syndrome (pSS) is chronic autoimmune disorder of unknown ethiopathogenesis. In line with the concept of neuroimmunohormonal dysregulation in inflammatory rheumatic diseases, the aim of this study was to investigate platelet serotonin level (PSL) in patients with pSS and its relation with the activity and duration of the disease. Significantly lower PSL in pSS patients (N=61) w...
S pontaneous portosystemic shunt (PSS) from portal hypertension is associated with portal vein (PV) stasis and chronic hepatic encephalopathy (HE). Embolization of PSS is effective in select cases of refractory HE, but is relatively contraindicated in patients with portal vein thrombosis (PVT) (Table 1). This procedure redirects significant blood flow back through the PV and has been reported t...
In this paper we introduce the idea of probability in the definition of a Sequential Dynamical System (SDS), thus obtaining a new concept, that of Probabilistic Sequential System (PSS). Due to its particular dynamic, the Probabilistic Boolean Network (PBN) model has been applied to genetic regulatory networks. The model we introduce combines the sequential aspect of the SDSs and the dynamic of ...
Three-dimensional (3D) urchin-like MnO2@poly (sodium 4-styrene sulfonate) (PSS)/poly (diallyl dimethylammonium chloride) (PDDA)/PSS particles were prepared via the layer-by-layer (LBL) assembly of polyelectrolytes for extraction Zn2+ from alkaline media. The adsorption performance on MnO2, MnO2@PSS/PDDA/PSS, and MnO2@(PSS/PDDA)3/PSS was investigated in batch experiments. MnO2@PSS/PDDA/PSS has b...
INTRODUCTION Primary Sjögren's Syndrome (pSS) affects exocrine glands such as those producing the tear film, leading to dry and painful eyes, but is also associated with fatigue. The experience of fatigue in pSS, and its relationship with sicca symptoms, is poorly understood. METHODS Twenty people diagnosed with pSS were recruited to participate in a semi-structured qualitative interview abou...
