The aim of this study is to investigate the patterns and trends drought occurrence in northern part Poland on example Łeba river basin years 1956–2015. meteorological was conducted basis Standardized Precipitation Index (SPI) scale 1, 3, 6, 9, 12 months. Annual precipitation totals did not show significant changes analyzed period, except for station Wejherowo, which characterized by a increasin...

The goal of this study is to calculate meteorological drought using the Standard Precipitation Index (SPI) and Evapotranspiration (SPEI) for Al-Lith Khafji basins Kingdom Saudi Arabia (KSA) from 2001 2020. in situ (rain gauges, RGs) Integrated Multi-satellite Retrievals GPM (IMERG) data are used current study. monitored across AL-Lith watersheds. climate watershed like some extent. Still, due c...

BACKGROUND Surgeries are inevitable for treating primary congenital glaucoma (PCG) and risk factors of surgical failure play a key role in surgical decision making. The aim of this study was to investigate the influence of delay of surgery and preoperative speed of progression (SP) on the surgical outcomes in these patients. METHODS Medical records of 83 eyes of 51 PCG patients with trabeculo...

Drought is an environmental disaster related to the extremes (on a drier side) in hydrometeorology. The precipitation amount modulates drought Nepalese river basins. It vital for efficient water resources management quantify and understand drought. This paper aims characterize droughts Nepal based on standard index (SPI) rainfall anomaly (RAI) using daily data assess their impacts annual crop y...

OBJECTIVE: Spiral Projection Imaging (SPI) is a versatile, fast 3D data acquisition. Data are sampled on 2D spiral planes that are rotated to fill a sphere in k-space (figure 1). The spiral basis of SPI provides flow insensitivity. Furthermore, it has been shown that SPI allows for six degrees of motion correction similar to that used in PROPELLER. SPI requires far fewer excitations than a line...

In this paper we present findings from our recent empirical study of software process improvement (SPI) implementation critical barriers (CBs) in twenty-six Australian software companies. The objective of this study is to summarise the issues that playa negative role in the implementation of SPI programmes and to identify the key barriers. Through our empirical study we identified 5 barriers (o...

OBJECTIVES To identify factors affecting doctors' engagement with the Safer Patients Initiative (SPI). DESIGN Qualitative interview study. SETTING Four organisations participating in phase 1 of the SPI programme, from four different geographical locations in the UK. PARTICIPANTS 34 staff members, comprising senior executive/management leads involved in the SPI programme, the principal SPI...

Assessment of spatiotemporal variations drought is an efficient method for implementing mitigation strategies and reducing its negative impacts. This study aimed to assess the pattern short- long-term droughts area with different climates. Therefore, 31 stations located in Iran were selected Standardized Precipitation Index (SPI) series timescales 3, 6, 12 months computed during 1951-2016 perio...

BACKGROUND South African HIV-infected infants below age 6 months and children younger than 3 years on concomitant antimycobacterial treatment received full-dose ritonavir single protease inhibitor (RTV-sPI), together with 2 nucleoside reverse transcriptase inhibitors, from 2004 until 2008. Use of RTV-sPI has been described as a risk factor for PI drug resistance, but the extent of this resistan...

Expression of the granzyme B inhibitors, human proteinase inhibitor 9 (PI-9), or the murine orthologue, serine proteinase inhibitor 6 (SPI-6), confers resistance to CTL or NK killing by perforin- and granzyme-dependent effector mechanisms. In light of prior studies indicating that virally infected hepatocytes are selectively resistant to this CTL effector mechanism, the present studies investig...
