Haiping Dai,Xinning Yang,Tingwei Dong,Yongwen Ke
Modern Applied Science , 2010, DOI: 10.5539/mas.v4n9p103
Abstract: According to the characteristics of beer brewing wastewater, Up-flow Anaerobic Sludge Bed and Membrane Bio-Reactor integrated technics (UASB+MBR) was applied. This paper investigated various operating parameters during the process of wastewater treatment in MBRs. The sludge loading and the membrane fouling were analyzed by detecting the sludge concentration and sludge characteristics. The results showed that when CODCr, NH4-N, T-P and T-N concentrations of the feed water were 500~1000mg/L, 20~30mg/L, 0.6~14mg/L and 19.5~41.1mg/L, respectively, it got some conclusions in the process.(1)The CODCr , NH4-N , T-P and T-N of MBR effluent could reduce to 40mg/L, 2.3mg/L , 0.3mg/L, 3mg/L, respectively. The quality of the effluent water in this system met the reuse of urban recycling water—Water quality standard landscaping water according to GB/T18921-2002; (2)The DO of the aerobic pool should be controlled at the range of 2~4mg/L, which could increase the removing efficiency of the NH4-N. (3)Appropriate adjustments to the volume of sludge and maintain the sludge concentration of membrane pool at 6~8g /L, which could reduce the velocity of membrane fouling. (4) With 1000mg/L of sodium hypochlorite and 2000mg/L hydrochloric acid alternate cleaning, the recovery of membrane flux can maintain above 95%.
Films of Carbon Nanomaterials for Transparent Conductors
Xinning Ho,Jun Wei
Materials , 2013, DOI: 10.3390/ma6062155
Abstract: The demand for transparent conductors is expected to grow rapidly as electronic devices, such as touch screens, displays, solid state lighting and photovoltaics become ubiquitous in our lives. Doped metal oxides, especially indium tin oxide, are the commonly used materials for transparent conductors. As there are some drawbacks to this class of materials, exploration of alternative materials has been conducted. There is an interest in films of carbon nanomaterials such as, carbon nanotubes and graphene as they exhibit outstanding properties. This article reviews the synthesis and assembly of these films and their post-treatment. These processes determine the film performance and understanding of this platform will be useful for future work to improve the film performance.

A variant of a type V lateral clavicle fracture involving a posteriorly displaced medial segment. A case report
Goss Thomas P,Li Xinning
Sports Medicine, Arthroscopy, Rehabilitation, Therapy & Technology , 2012, DOI: 10.1186/1758-2555-4-47
Abstract: The clavicle connects the shoulder girdle to the axial skeleton, providing support and mobility for optimal upper extremity function. Fractures of the clavicle account for up to 4% of all fractures and comprise up to 44% of all injuries to the shoulder girdle. We present a 63-year-old female patient who suffered what appeared to be a minimally displaced Type V lateral clavicle fracture after a fall as evidenced by an anteroposterior shoulder radiograph. However, an axillary projection demonstrated the proximal segment to be posteriorly displaced and buttonholed through the trapezius musculature with tenting of the skin. The patient underwent an open reduction and Kirschner wire fixation of the fracture with complete healing, subsequent removal of the hardware and return to her previous level of function six months following surgery. After an extensive literature search, we believe this is the first case report documenting a variant of a Type V lateral clavicle fracture, specifically with significant posterior displacement of the proximal segment, mimicking a Type IV AC separation. This fracture pattern is unstable and represents a double disruption of the superior shoulder suspensory complex. Surgical management was successful in returning our patient back to her previous activity of daily living.
A comparative study on communication structures of Chinese journals in the social sciences
Ping Zhou,Xinning Su,Loet Leydesdorff
Physics , 2010,
Abstract: We argue that the communication structures in the Chinese social sciences have not yet been sufficiently reformed. Citation patterns among Chinese domestic journals in three subject areas -- political science and marxism, library and information science, and economics -- are compared with their counterparts internationally. Like their colleagues in the natural and life sciences, Chinese scholars in the social sciences provide fewer references to journal publications than their international counterparts; like their international colleagues, social scientists provide fewer references than natural sciences. The resulting citation networks, therefore, are sparse. Nevertheless, the citation structures clearly suggest that the Chinese social sciences are far less specialized in terms of disciplinary delineations than their international counterparts. Marxism studies are more established than political science in China. In terms of the impact of the Chinese political system on academic fields, disciplines closely related to the political system are less specialized than those weakly related. In the discussion section, we explore reasons that may cause the current stagnation and provide policy recommendations.
Optimization of filtering criterion for SEQUEST database searching to improve proteome coverage in shotgun proteomics
Xinning Jiang, Xiaogang Jiang, Guanghui Han, Mingliang Ye, Hanfa Zou
BMC Bioinformatics , 2007, DOI: 10.1186/1471-2105-8-323
Abstract: In this study, we implemented a machine learning approach known as predictive genetic algorithm (GA) for the optimization of filtering criteria to maximize the number of identified peptides at fixed false-discovery rate (FDR) for SEQUEST database searching. As the FDR was directly determined by decoy database search scheme, the GA based optimization approach did not require any pre-knowledge on the characteristics of the data set, which represented significant advantages over statistical approaches such as PeptideProphet. Compared with PeptideProphet, the GA based approach can achieve similar performance in distinguishing true from false assignment with only 1/10 of the processing time. Moreover, the GA based approach can be easily extended to process other database search results as it did not rely on any assumption on the data.Our results indicated that filtering criteria should be optimized individually for different samples. The new developed software using GA provides a convenient and fast way to create tailored optimal criteria for different proteome samples to improve proteome coverage.Because of the high sensitivity, mass spectrometry has been widely used for protein identification and characterization in proteome researches within the past decade[1,2]. Shotgun proteome approach, which is based on analysis using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS), can be applied to analyze complex protein mixtures directly even without any prior purification step. Large-scale proteome profiling using multidimensional LC-MS/MS has become increasingly applied for the analysis of many biological samples, including various mammalian tissues, cell lines, and serum/plasma [3-8]. In shotgun proteomics, complex protein mixtures are first digested by the enzyme (e.g. trypsin) to produce peptide mixtures. Then the peptide mixtures are subjected to extensive separations such as strong cation exchange chromatography (SCX) coupling with on-line or off-

Abstract: Ankle sprains are common injuries seen in the young and athletic population with majority of the cases involving the lateral ligamentous complex [1-3]. Much of the literature has been written about the operative and non-operative treatment of severe lateral ankle sprains and the possible sequelae of chronic instability of the ankle [4-14]. A majority of the patients will improve following a treatment protocol involving a period of rest and physical therapy. However, it has been noted in previous studies that as many as twenty percent of patients will have chronic symptomatic ankle instability [5,15,16]. The treatment of chronic ankle instability in patients who have failed a course of supervised and aggressive physical therapy, poses a challenge to the orthopedic surgeon. Many different techniques have been described in the operative treatment for chronic lateral ankle instability that involves either anatomic or non-anatomic repairs (tenodesis) [13,14,17-20]. Brostr?m described an anatomic primary repair technique in 1966 [21] and Gould subsequently modified this technique by advancing the extensor retinaculum to reinforce the repair [22].This manuscript describes another variant to the Gould modified Brostr?m repair using three suture anchors. This technique involves anatomic reconstruction of both the Anterior Talo-fibular Ligament (ATFL) and Calcaneal Fibular Ligament (CFL). A third suture anchor is also used proximal to the ATFL insertion to reinforce the repair anatomically.Each patient received general anesthesia with a peroneal nerve block. The patient was placed in a supine position with a towel bump under the ipsilateral buttock. A thigh tourniquet was utilized during the operation to control bleeding (250 mmHG). Once the patient was anesthetized, their ankle was evaluated for baseline range of motion and laxity. Next, a two inch curvilinear incision was made anteriorly over the lateral malleoli with a #15 blade (Figure 1). Care is taken to identify and av
Medial pelvic migration of the lag screw in a short gamma nail after hip fracture fixation: a case report and review of the literature

Abstract: Hip fractures are a common injury among adults ages 65 and older, occurring in approximately 300,000 individuals yearly [1,2]. An estimated 1.66 million hip fractures occurred worldwide in 1990 and the number is expected to increase to 6.26 million by the year 2050 [3]. Internal fixation with an intramedullary (IM) system has gained popularity for the treatment of intertrochanteric femur fractures. This construct provides both load sharing properties while allowing immediate mobilization [4,5]. Complications of IM hip fracture fixation include but not limited to infection, mal or non union, avascular necrosis, hardware failure, neurovascular injuries, fracture of the femur distal to the implant, and death [3-5].A common complication associated with the IM system is lag screw cut-out from the femoral head which leads to varus collapse of the fracture and non-union [6-8]. Other rare complications related to the lag screw include medial pelvic migration [9], lateral migration [10], extracorporeal extrusion from the body [11], and sigmoid perforation [8]. Furthermore, medial migration of the proximal femoral element seen with the Proximal Femoral Nail described as the "Z Effect" have also been reported [12]. We believe this is the first case report presenting medial pelvic migration of the lag screw or femoral neck element of a short Gamma 3 IM nail in a locked and stable construct ten weeks post surgery. The patient was subsequently treated with Lag Screw removal and revision surgery with a shorter Lag Screw and an accessory cannulated screw acting as a de-rotational device.The patient was a 77 year old Caucasian female who experienced a mechanical fall onto her right side and presented to our emergency department. On physical examination, the patient had a shortened and externally rotated right lower extremity that was painful to log-roll and axial load. Otherwise the patient was neurovascularly intact. The initial radiographs showed a 3- part inter-trochanteric hip f

Abstract: MRI studies taken at one imaging site between January, 2007 to January, 2008 with the final diagnosis of patella dislocation were screened for this study. Of the 324 cases that were found, 195 patients with lateral patellar dislocation traumatic enough to cause bone bruises on the lateral femoral trochlea and the medial facet of the patella were selected for this study. The MRI images were reviewed by three independent observers for location and type of MPFL injury, osteochondral defects, loose bodies, MCL and meniscus tears. The data was analyzed as a single cohort and by gender.This study consisted of 127 males and 68 females; mean age of 23 yrs. Tear of the MPFL at the patellar attachment occurred in 93/195 knees (47%), at the femoral attachment in 50/195 knees (26%), and at both the femoral and patella attachment sites in 26/195 knees (13%). Attenuation of the MPFL without rupture occurred in 26/195 knees (13%). Associated findings included loose bodies in 23/195 (13%), meniscus tears 41/195 (21%), patella avulsion/fracture in 14/195 (7%), medial collateral ligament sprains/tears in 37/195 (19%) and osteochondral lesions in 96/195 knees (49%). Statistical analysis showed females had significantly more associated meniscus tears than the males (27% vs. 17%, p = 0.04). Although not statistically significant, osteochondral lesions were seen more in male patients with acute patella dislocation (52% vs. 42%, p = 0.08).Patients who present with lateral patella dislocation with the classic bone bruise pattern seen on MRI will likely rupture the MPFL at the patellar side. Females are more likely to have an associated meniscal tear than males; however, more males have underlying osteochondral lesions. Given the high percentage of associated pathology, we recommend a MRI of the knee in all patients who present with acute patella dislocation.Acute lateral patella dislocations are common injury pattern seen in the younger and athletic population that presents to orthopaedic
