Based on the published studies of foreign and Albanian researchers, we have analyzed the current level of information about the distribution of this class in Albania. In this study we mainly focused in the Southern Region of Albania by assessing the biodiversity of the diplopods. The study area covers the Ionian coast and parts of Vjosa river valley. This study has made use of determination key of Mauries J. color, number of segments, number of paired limbs to distinguish the different species. The collected data are compared with previous findings by Verhoeff （1901）, Attems （1929）, Manfredi （1945）, Mauriès, Go lovatch, Stoev （1997） etc. The distribution range of the collected species is presented according to the national or Balkan level. Based on the recent studies and the geographical distribution of diplopods, we expect to find approximately 150 species of 50 genres in Albania.展开更多

We hypothesized that the benefit provided by the reperfusion of left anterior descending （LAD） territories and the biological angiogenetic drive triggered by the revascularization could translate in a global improvement in ventricular contractility, not restricted to the grafted area. Methods High-risk patients with multivessel coronary artery disease and preoperative wall motion abnormalities were retrospectively analyzed to compare outcomes and regional ventricular function of those who received optimal medical therapy （OMT） versus those who underwent off-pump coronary artery bypass grafting （OPCABG） and received an incomplete myocardial revascularization using left internal mammary artery （LIMA） on LAD （OPCABG group）. From January 2007 to December 2014, 206 patients （OMT, n = 136, OPCABG, n = 70） were propensity-score matched to have 70 matched pairs. Variables included in propensity score analyses were ejection fraction （EF）, left ventricular end diastolic volume （LVEDVi）, EuroSCORE II. Primary endpoint was the variation in the global wall motion score index （AWMSI） as evaluated by transthoracic echocardiography. Follow up was completed at 3 years from surgery or hospital discharge. Results Regional analysis of ventricular function revealed a regional WMSI improvement in the OPCABG group not only for LAD territories but also for non-LAD regions, associated with a reduction in the negative left ventricular ischemic remodeling, compared to patients discharged in optimal medical therapy. Global AWMSI was negative in OPCABG group （-3.4 ± 2.8%） and positive in the OMT group （5.9 ± 3.1%）, indicating a better wall motion score for OPCAB patients. Surprisingly, regional WMSI improved also in non-grafted territories in the off-pump CABG group with a delta value of -3.7 ± 5.3% for left circumflex artery （LCX） area and -3.5 ± 5.4% for right coronary artery （RCA） area. Conclusions In patients with multivessel coronary artery disease, LIMA-to-LAD grafting is associated with an improvement in the WMSI involving also the surrounding non-LAD ungrafted segments and with the attenuation of negative global and regional ischemic ventricular remodeling.展开更多

Although Malaysia is not located in the active fault seismic area, it is closed to the Sumatran active seismic zones. Tall building are fIequently felt the tremor generated fTom Sumatran subduction and fault zones especially in the west cost of Peninsular Malaysia such as Johor Bahru, Kuala Lumpur and Penang. Existing design response spectra was developed based on attenuation relationship for each subduction and fault zone. In this study, the design response spectra were developed based on various attenuation relationships for selected location in Kuala Lumpur area, namely, Mutiara Damansara, Bandar Petaling Jaya and Bandar Puteri Puchong. The development of design response spectra based on various attenuation relationships is more reliable in selecting the appropriate attenuation relationship for the study area. Seven attenuations have been chosen and results show that Megawati et al. are the most appropriate attenuation relation for fault zone, where the predicted PGA （peak ground acceleration） is 0.0187 g which is the proposed PGA value for this study area. This study also found that most of soil in the study area can be categorized into SD （stiff soil） according to site classification in the NEHRP 2000 Provision/UBC 97. Bandar petaling Jaya was found to be highest AF （amplification factor） of 3.74 for stiff soil and Mutiara Damansara with AF of 2.67 for very dense soil or soft rock. The proposed design response spectra for each location were developed based on UBC 1997 （Uniform Building Code 1997）. The peak RSA （response spectrum acceleration） of 0.30 g for soil type SD for Bandar Petaling Jaya is the maximum level of acceleration on the soil surface with a period range of 0.10 to 0.52 seconds. All these values can be used for the seismic safety evaluation of existing structures and as a guideline in designing new structures to resist future earthquake, within the study area.展开更多
