First Report of Zircon U-Pb Ages from Lubei Cu-Ni Sulfide Deposit in East Tianshan of Central Asian Orogenic Belt, NW China

Objective The East Tianshan mafic-ultramafic rocks belt mainly produced in the eastern Jueluotage belt is an important part of the Central Asia Orogenic Belt （CAOB）. The well- known deposits including Huangshan, Huangshandong, Tulaergen, Hulu, Xiangshan were have been consecutively discovered in this belt （Duan Xingxing et al., 2016）. The new discovery of the Lubei Cu-Ni sulfide deposit in recent years, which locates in the west of Jueluotage belt, has great significance to the westward extension of the East Tianshan Cu-Ni metallogenic belt. To determine whether the mineralization age of the Lubei Cu-Ni sulfide deposit is consistent with other typical deposits, this study conducted zircon U-Pb geochronology on the diorite from the Lubei Cu-Ni sulfide deposit in order to provide new information for further exploring direction of Cu-Ni prospecting in East Tianshan.

First report of cereal cyst nematode(Heterodera filipjevi) on winter wheat in Shandong Province, China

The cereal cyst nematodes(Heterodera avenae,Heterodera filipjevi,Heterodera latipons)are considered to be one of the most important plant parasitic nematodes attacking most cereals and can cause significant crop losses(Sikora 1988).In China,H.filipjevi(Madzhidov 1981)Stelter,1984,was first reported from Henan province(peng et al.2010)and a few years later in Anhui province and Xinjiang Uygur Autonomous Region(peng et al.2016,2018).In December 2017,a survey for cereal

The First Report of Thermochemical Sulfate Reduction Reaction in the Upper Paleozoic Carbonate Rocks of Southeastern Ordos Basin

Thermochemical sulfate reduction （TSR） is the reaction between anhydrite and petroleum fluids at elevated temperatures to produce H2S and CO2. TSR has been studied in many sedimentary basins such as China＇s Sichuan and Tarim basins because it has a profound impact on the commercial viability of petroleum resources, with HzS typically being undesirable.

First Report of Avian Tracks from the Cretaceous of Tibet, China

Objective Despite a large number of bird fossils in the Jehol Biota, Mesozoic bird records from other parts of China are dominated by tracks. Late Cretaceous bird tracks are rarely found in China. Reliable reports so far include a Dongyangornipes and Koreanaornis assemblage of early Late Cretaceous age from Dongyang City, Zhejiang Province, China （Azuma et al., 2013）. Buckley et al. （2016） consider Dongyangornipes sinensis a subjective junior synonym of Uhangrichnus chuni. Type Uhangrichnus chuni （Yang et al. 1995; Lockley et al., 2012） from the Uhangri Formation, Hwangsan Basin of South Korea is Late Cretaceous in age, and the trackrnaker was a web-footed avian.

First Report of Late Miocene Mammals Including Chilotherium in the Xining Basin,NE Tibetan Plateau,China

Objective Xining basin is located in the northeastern Qinghai- Tibetan Plateau, which tectonic location belongs to a junction of the Kunlun and Qilian mountains. The southern, northern and western parts of the basin are restricted by the Laji, Daban and Riyue mountains fault zones, and go eastward into the Longzhong basin in Gansu Province. A succession of Cenozoic lacustrine sedimentary strata has been well developed in the Xining basin, with sediments over 800 m thick.

First Report of Zircon U-Pb Chronology and Hf Isotope Evidence of the Heluositan Group Granulite in West Kunlun, Xinjiang

Objective As the uplift belt on the southem margin of the Tarim block, the Tiekelike block consists mainly of a set of Precambrian metamorphic rocks with granulite and gneisses. The Heluositan group-complex is the most ancient rock series in the area, and is a key area for studying the formation and evolution of the Precambrian basement of the Tarim craton. LA-ICP-MS zircon U-Pb dating and Hf isotopic analysis of granulite in this area provide new evidence for revealing the formation and evolution of the Precambrian basement in the Tarim Basin.

First Report of an Outbreak of Contagious Ecthyma in Camels （Camelus dromedarius and Camelus bactrianus） in Iran

Camel contagious ecthyma （CCE） has been reported in Mongolia, Kenya, Somalia and Sudan. CCE is caused by a Parapoxvirus affecting young animals by producing lesions around the lips and nostrils. The generalized form of CCE is uncommon. The aim of this study was to submit the first report of contagious ecthyma in Iran and also to help clinician to diagnose this disease with heavy economic losses easier. In the paper, an outbreak of CCE in dromedary and bactrian camels in Qom province of Iran was described and clinical signs were observed in one camel herd in October 2009. Nodules and scabs from seven affected animals were collected for virus identification. Total extracted DNA was used for polymerase chain reaction （PCR） to amplify a fragment of Parapoxvirus B2L gene. Results showed that camel calves （n = 27） less than one year old and one male bactrian camel were affected （no adult female camels were found to be infected）. The prevalence of the disease in the herd, adult camels and camel calves was 30.33%, 1.5% and 100%, respectively. Affected animals showed the swelling of head with nodular lesion around the lips. It then developed to pustules and fissured crusts. Previous involvement with this disease, history of contact with sheep or goats, food resources and season all can have a role in epidemiology of the disease.

THE FIRST REPORT OF ECHINOCOCCUS MULTILOCULARIS IN DOMESTIC DOGS IN ZHANG COUNTY OF GANSU PROVINCE

In Zhang County of Gansu Province, 13 human cases of alveolar hydatid disease were reported up to 1990. However, the causative organism has not yet been described in animal hosts. In July 1990, postmortem examinations were made on 59 dogs (Canis familiaris) from the Caotan region of Zhang County. Of them, 6 were found to be infected with the adult worms of Echinococcus multilocularis. The morphological characteristics of the adult were compared in detail with those reported from different parts of China. Our adult specimens were closely resembling those of E. multilocularis reported from Ningxia. The role of domestic dogs in the epidemiology of alveolar echinococcosis in Zhang County was discussed.

山东地震台网监测预警能力评估分析

国家地震烈度速报与预警项目已进入试运行阶段,山东全省作为重点预警区,其预警能力直接关系山东及其周边地区的预警效能。为精确评估山东地震台网的监测预警能力,以本台网所记录到的波形数据为基础,将仪器最大概率峰值位移作为背景噪声评估指标获得山东地震台网的监测能力。在此基础上,考虑到预警时效性需求,系统评估了山东地震台网中,由125台速度计组成的测震台网、由152台加速度计组成的强震台网、由1198台烈度仪组成的烈度台网及其融合网的预警最小震级和首报时间。结果表明,山东地震台网平均监测能力达到M_(L)0.4,最小值可达M_(L)-0.2,最大值可达M_(L)1.1;测震、强震和烈度台网“三网”融合后预警最小震级、首台触发后和震后的预警时间平均值分别约为M_(L)2.2、3s和5s,“三网”融合进行预警的策略可以满足地震预警“稳、准、快”的要求。

Quality Control of First Trimester Ultrasound Examinations in the Gynecology and Obstetrics Department of the University Teaching Hospital Yalgado Ouedraogo (UTH-YO) of Ouagadougou, Burkina Faso

Objective: To evaluate the quality of first trimester ultrasound examinations in patients consulting in the gynecology and obstetrics department at the University Teaching Hospital Yalgado Ouedraogo (UTH-YO) of Ouagadougou. Method: Our study took place from January 1st to March 31st 2017, in the department of Obstetrics and Gynecology of the University Teaching Hospital Yalgado Ouedraogo of Ouagadougou. This was a descriptive study on the records of the first trimester ultrasound of pregnancy, with analysis of the iconography. We used the criteria of the Technical Committee of Fetal Echography (TCFE) of France to analyse all the ultrasound reports brought by the patients. Results: Two hundred reports were collected in three months. In terms of ultrasound identification, only 2 reports out of 200 mentioned the brand and date of first circulation and 4 specified the type of device. The study of the quality of the appointment showed that only 52% of the ultrasounds had been performed at the right time, between 11SA - 14SA of amenorrhea. For the nuchal translucency quality, we rated by the Herman score, 41.67% of the scores were of “unacceptable” quality and only 58.33% were of “acceptable” quality we did not achieve “excellent” quality. The analysis of the biparietal diameter (BIP) cuts revealed that 1/4 only anatomical cuts had been well made. Analysis of the cranio caudal length (CCL) cuts showed that only 14.58% of the CCLs had been well done. Elements of early morphology had been explored to less than 5%. Conclusion: The results revealed the acceptable quality of the NC measurements, but a small proportion of NC achieved. The quality of the ultrasound, morphological analysis and biometrics period is not very acceptable.

我国首例因Asaia sp.污染而导致含果汁及果肉饮料变质的案例分析

某含椰果粒椰汁饮料发生变质，外观正常，经检测发现细菌严重超标。污染菌通过16srDNA序列比对鉴定为Asaiasp．，这是该属微生物第一次在我国检出。该菌能耐受pH值3．O～3．5的酸性环境，能耐受75℃、30ming或80％、10min热处理，耐受0．8g／kg浓度的山梨酸钾。尤其值得重视的是：该菌在36℃～37℃平板计数琼脂培养基上不生长，所以根据GB47892—2010食品安全国家标准食品微生物检验菌落总数测定规定的方法无法检出该污染菌。因其耐酸、耐热、耐防腐剂和多种抗生素、产生物膜能力较强的特性，Asaiasp．细菌可能对水果、果汁等产品的安全性造成不可忽视的影响。
