This article focuses on modelling and mapping the productivity of black (Picea mariana) and white spruce (Picea glauca) plantations across the Black Brook forest management area in northwestern New Brunswick, Canada, encompassing about 200,000 ha. This effort involved establishing 3500 50 m2 survey plots, each informing about: plantation age (15 to 43 years), planted species type, stem count, tree height, basal area, and wood volume. All of this was supplemented with location-specific productivity predictors, i.e., xy location and specifications pertaining to soil type, soil drainage (established through digital elevation modelling by way of the depth-to-water index DTW), and years since thinning (pre-commercial and commercial), and. The DTW index, as it emulates the elevation rise away from open water features such as streams, rivers and lakes, allowed the re-mapping of existing soil borders by topographic position and drainage association. Non-linear regression analysis revealed that plantation height, basal area and volume all increased with plantation age, as to be expected. Pre-commercial thinning in plantations <30 years old had a positive while the more recent commercial thinning still had the negative effect on standing wood volume and mean annual volume increment (MAI). White spruce MAI generally exceeded black spruce (MAI) by a factor of 1.25. Poor and excessive soil drainage reduced MAI. Best growth performances occurred on plantations established on well-drained calcareous soils. The best-fitted results so obtained allowed for generating black and white spruce MAI maps across the forest management area by ridge-to-valley soil and DTW location at 10 m resolution. These maps were subsequently used for site-by-site silvicultural evaluation and ranking purposes.

We investigated the compositional and structural differences in sequences derived from different fractions of wheat genomic DNA obtained using methylation filtration and Cot fractionation. Comparative analysis of these sequences revealed large compositional and structural variations in terms of GC content, different structural elements including repeat sequences （e.g., transposable elements and simple sequence repeats）, protein coding genes, and non-coding RNA genes. A correlation between methylation status [determined on the basis of selective inclusion/ exclusion in methylation-filtered （MF） library] of different repeat elements and expression level was observed. The expression levels were determined by comparing MF sequences with expressed sequence tags （ESTs） available in the public domain. Only a limited overlap among ME high Cot （HC）, and ESTs was observed, suggesting that these sequences may largely either represent the low-copy non-transcribed sequences or include genes with low expression levels. Thus, these results indicated a need to study MF and HC sequences along with ESTs to fully appreciate complexity of wheat gene space.

The activity concentration of natural and fallout radionuclides in the soil at some selected Thanas around the TRIGA Mark-II Research Reactor at Atomic Energy Research Establishment (AERE), Savar, Dhaka were measured by using a high purity germanium detector (HPGe). The study revealed that only natural radionuclides were present in the samples and no trace of any artificial radionuclide was found. The average activity concentration of 238U, 232Th and 40K were found to be 37.8 ± 5.6 ***-1, 58.2 ± 11.0 ***-1 and 790.8 ± 153.4 ***-1 respectively. The radium equivalent activity (Req), absorbed dose rate (D), external radiation hazard index (Hex) and internal radiation hazard index (Hin) were also calculated to find out the probable radiological hazard of the natural radioactivity.

East Asians are the most populous race in the world and their health status is an important global *** with Caucasian populations, East Asian patients have a different benefit/risk ratio when using antithrombotic treatment. Despite this observation, treatment strategies in East Asian patients are mostly based on the American and European guidelines. Despite a lower platelet inhibitory response to clopidogrel, East Asian patients show a similar or even a lower rate of ischemic event occurrence and higher bleeding risk compared with Caucasian patients. For potent P2Y_(12) inhibitors(ticagrelor and prasugrel),East Asian patients have shown less favorable net clinical benefits compared with Caucasian patients,which may be related to differences in pharmacokinetic/pharmacodynamic profiles and therapeutic zone of antiplatelet effect. This updated consensus mainly focuses on state-of-the-art and current controversies in the East Asian population. In addition, when East Asian patients are administered potent P2Y_(12) receptor inhibitors, the strategies and ongoing trials to overcome the related hurdles are discussed.

The high population growth rate has been associated with the increased level of poverty, morbidity, mortality, and decreased life expectancy. Modern contraception is an important factor in controlling fertility through prevention of unintended and unwanted pregnancies. Contraception (birth control) prevents pregnancy by interfering with the normal process of ovulation, fertilization, and implantation. Contraceptive use is still very low in Nigeria and Sub-Saharan Africa (SSA), where the levels of fertility and unmet need for family planning are high. The attitude of women toward contraception will usually affect the practice and utilization of contraceptives. The objective of this study is to assess the attitude, prevalence, and factors affecting contraceptive use among women attending Postnatal care in a tertiary health facility in Jos North L. G. A Plateau State, Nigeria. There was a descriptive cross-sectional study done between September to October 2019, with a sample size of 250 women. Respondents were determined using a multi-stage sampling method. Data collection was done using an interviewer-administered, pre-tested, structured questionnaire. The data was collected, entered, and analyzed using IBM Statistical package for social sciences (SPSS) version 20.0. Most women have a positive attitude 162 (64.8%) toward contraception while 88 (35.2%) had negative attitude toward contraception. Three quarters (75.2%) of women are willing to use contraception. The prevalence of contraceptive use among respondents was 35.6% while the prevalence of previous use of contraceptives among the respondents was 71.2%. Fifty (27.9%) used condom (barrier method), 40 (22.9%) used withdrawal method. Majority of the other respondents were spread across OCPs, injectables and implants. Major factors affecting the use of contraceptives were majorly attributed to informed choice with 60.1%, Partner’s decision (44.1%) and mild or no adverse reaction (12.8%). While major factors preventin

这一切的开始就像一场玩笑。当时我在Internet上看到了明显虚假的Longhorn屏幕截图，让我感到很失望，于是我在2002年1月发表了我的第一个Road to Windows Longhorn Showcase——没错，那是4年前的事了。当时的Longhorn（也就是现在的Windows Vista）仅仅是一个梦想，而Windows的狂热爱好者们则忙着制作假的屏幕截图，声称下一代Windows将会是那个样子，或者说他们期望它会变成那样。
