An assessment of the protective capacity of the vadose zone overlyingthe aquifer systems in the Kaltungo area was carried out to determine itsinfluence on groundwater quality. Applying the schlumberger array with amaximum electrode spread AB/2 = 100m through VES, thirty water wellpoints were surveyed using Omega terrameter (PiOSO1) resistivity *** field data was first subjected to manual interpretation through curvemarching and then digitized modeled curves using computer software. Theinterpreted data revealed that the area is characterized by eleven differentcurve types representing three to five geo electrical layers. in order toassess the protective capacity of the vadoze zone over the aquifer systems,the longitudinal conductance (S) and transverse resistance (T) (secondarygeoelectric parameters) were computed from the primary data using theDar Zarouk formula. The values of S obtained range from 0.0018 to 0.4056ohms with a mean value of 0.0135 ohms while the values of T range from0.55 ohms to 1195.68 ohms with a mean value of 39.84 ohms. The valuesof S and T obtained reveal that 90% of probed points has poor protectivecapacity, 10 % has moderate protective capacity and 83 % has hightransmissivity, 17 % has intermediate transmissivity. The T and S values areskewed towards poorly protective capacity thus making groundwater in thearea highly vulnerable to contamination from the surface. To achieve goodgroundwater quality in the area, proper completion of newly constructedwells should install protective casing through the entire vadose zone.

葡萄渣浓缩物含有丰富的具有强抗氧化能力的多酚。试验旨在研究α-生育酚盐酸盐(200mg/kg)及15g/kg、30g/kg、60g/kg三个水平的葡萄渣浓缩物(GPC)对肉鸡(21～42日龄)的生产性能、消化器官容量、蛋白质、脂肪、冰冻胸肌的氧化易感性、水解多酚和缩合丹宁的可消化性以及日粮、血清、回肠内容物和排泄物的抗氧化活性等方面的影响。GPC对生产性能、回肠粗蛋白表观消化率、肠相关长度及腹脂、肝脏、胰腺、脾脏的相对重量不产生影响。在基础日粮、添加GPC日粮与添加维生素E的日粮对照中,后者实验鸡的脂肪消化率较前两者高。GPC日粮能减少回肠和粪便中水解多酚的可消化性。水解多酚和缩合丹宁在回肠粪便中的的消化率分别为56%～73%和14%～47%。GPC日粮能减少回肠和粪便中水解多酚的可消化性。GPC日粮、回肠内容物和排泄物[2,2-联氮基-双-(3-乙基苯并二氢噻唑啉)-6-磺酸法]抗氧化活性以及GPC日粮(三价铁抗氧化能力方式)较基础日粮和维生素E日粮具有更高的清除自由基能力。饲喂维生素E日粮与基础日粮相比,胸肌在分别冰冻储存1、4和7d后油脂氧化作用降低。而饲喂GPC日粮与维生素E日粮相比,鸡胸肌在分别储存1、4、7d后在氧化稳定性方面更平衡。总之,添加GPC(达到60g/kg)的日粮不会对肉鸡的生长性能、消化器官容量以及蛋白质的消化性能产生影响。水解多酚与缩合丹宁相比更具生物有效性。GPC日粮中的日粮、排泄物、回肠内容物和胸肌的抗氧化能力皆有提高。GPC添加物具有与维生素E相同的抗氧化效果。基于这些发现,我们可以推断GPC在动物营养中将是一种新的抗氧化剂资源。

Enhanced thermal transport across monolayer MoS2

引用

Nano Research 2018年第4期11卷 2173-2180页

作者： Miguel goni Jia Yang Aaron J. Schmidt 110 Cummington mall Mechanical Engineering Boston University Boston 02115 USA

Characterizing the thermal properties of MoS2 is important for the design of electronic devices based on this material. We used frequency domain thermoreflectance to study the cross-plane thermal transport in mechanically exfoliated MoS2 samples supported on SiO2 and muscovite mica substrates. The thickness of MoS2 ranged between one and five layers, and the MoS2 layers were sandwiched between a metal layer and the substrate. in the case of mica, heat transport into the substrate remained the same whether or not a monolayer of MoS2 was present, whereas, for SiO2, heat transport was reduced by surface roughness. We observed a significant improvement in heat transport across monolayer MoS2 as compared to few layer MoS2. For MoS2 on SiO2, the effective thermal interface conductance was improved by more than three times if a monolayer was used. For MoS2 on mica, the thermal interface conductance was approximately two times better for monolayer MoS2. This implies that monolayer MoS2 has superior thermal properties and can be used in electronic devices as an intermediate layer between two materials. Additionally, we also report on the measurement of anisotropic thermal conductivity in bulk MoS2 and mica.

N,N-Diallyl methionine ethyl ester hydrochloride 5 underwent alternating copolymerization with SO_2 via the Butler cyclopolymerization protocol in dimethyl sulfoxide(DMSO) to give water-soluble cycloterpolymer 6 with a ～1:1 molar ratio of sulfide and sulfoxide groups as a result of oxygen transfer from DMSO. Half of the sulfide groups in 6, upon oxidation with H_2O_2, afforded polymer sulfoxide 7 and polymer sulfone 8. The solution properties of these polymers were determined via a viscometric technique. The thermal stability of these polymers was determined by thermogravimetric analysis. The inhibition efficiency obtained from gravimetric mass loss, potentiodynamic polarization, and electrochemical impedance spectroscopy techniques agreed well with each other. The corrosion efficiencies increase with increasing concentration of the polymers. At a polymer concentration of 175 mM, the maximum inhibition efficiency of copolymer compounds 6–8 was determined to be 92%, 97%, and 95%, respectively. The synthesized polymer compounds acted as mixed-type inhibitors. Polymer compound 7 adsorbed onto the metal surface via chemisorption and physisorption and obeyed Langmuir, Temkin, and Freundlich adsorption isotherms. Analyses by X-ray photoelectron spectroscopy and scanning electron microscopy–energy-dispersive X-ray spectroscopy indicated that the adsorbed polymers formed a thin film on the metal surface and prevented further corrosive attack.

The growth productivity of broilers is influenced by improving growth performance through improving body weight, average daily gain, and feed conversion rate. The objective of the study was to determine the effect of quantitative feed restriction duration on growth performance and carcass characteristics of broilers. A total of 144 day-old broiler chicks were reared in a deep litter system until slaughter at 42 days. Chicks were randomly allocated to three treatments which were replicated three times with 16 birds per replicate. The three treatments were the control (T1), one week of feed restriction (T2), and two weeks of feed restriction (T3). Birds were fed with starter, grower and finisher diets. The average daily gain (ADG), average daily feed intake (ADFI), and the feed conversion ratio (FCR) were computed for each week. Carcass weight and internal organs weights were measured. The body weight gained by the birds in T1 was similar to the birds that were restricted for a week. The treatments had a significant effect on the average daily gain in weeks 4, 5, and 6. The ADG for T2 was higher (P i>adi>i>ily:;" "=

Cephalomedullary fixation for femoral neck/intertrochanteric and ipsilateral shaft fractures： surgical tips and pitfalls

引用

Chinese Journal of Traumatology 2013年第1期16卷 40-45页

作者： Kamal Bali Nitesh Gahlot Sameer Aggarwal Vijay goni Department of Orthopaedic Surgery Post GraduateInstitute of Medical Education and Research ChandigarhIndia Department of Orthopaedics University of CalgaryAlberta Canada

Objective： Surgical management options for femoral shaft fracture and ipsilateral proximal fe- mur fracture vary from single-implant to double-implant fixation. Cephalomedullary fixation in such fractures has rela- tive advantages over other techniques especially because of less soft tissue dissection and immediate postoperative weight beating with accelerated rehabilitation. However, the surgery is technically demanding and there is a paucity of literature describing the surgical techniques for this fixation. The aim of the study was to describe the surgical technique of cephalomedullary fixation for femoral shaft fracture and ipsilateral proximal femur fracture. Methods： Sixteen cases （10 males and 6 females with a mean age of 41.8 years） of ipsilateral proximal femur and shaft fractures were treated by single-stage cephalomedullary fixation at tertiary level trauma center in northern india. The fractures were classified according to AO classification. An intraoperative record of duration of surgery as well as technical challenges unique to each fracture pattern was kept for all the patients. Results： The most common proximal femoral pattern was AO B2.1 observed in 9 of our patients. The AO B2.3 fractures were seen in 4 patients while the AO A1.2 fractures in 3 patients. Four of the AO B2.1 and 2 of the AO B2.3 frac- tures required open reduction with Watson-Jones approach. The mean operative time was around 78 minutes, which tended to decrease as the surgical experience increased. There was only one case of malreduction, which required revision surgery. Conclusion： Combination of ipsilateral femoral shaft fracture and neck/intertrochanteric fracture is a difficult frac- ture pattern for trauma surgeons. Cephalomedullary nail is an excellent implant for such fractures but it requires careful insertion to avoid complications. Surgery is technically demanding with a definite learning curve. Nevertheless, a majority of these fractures can be surgically managed by

引用

Open Journal of Animal Sciences 2016年第3期6卷 163-168页

Jersey bull calves and steers produce high quality meat;however, the growth rate of Jersey bull calves for veal and beef are low in comparison to other dairy breeds. This could be improved by crossbreeding with beef breeds. in the current study, the veal and beef production of Jersey and Fleckvieh × Jersey (F × J) bull calves and steers were compared. Bull calves were reared intensively for veal up to a carcass weight not exceeding 100 kg, or as steers for beef to 21 months of age. in both veal and steer production systems, the mean birth weight of F × J bull calves was higher (P i.e. 33.5 ± 1.2 kg vs. 27.9 ± 1.2 kg and (33.4 ± 0.9 kg vs. 26.9 ± 0.9 kg, respectively. The body weight of Jersey and F × J veal calves at 6 months of age differed (P ing 163.5 ± 3.9 and 180.6 ± 4.0 kg respectively. This could be attributed to a higher (P ily gain (ADG) of 0.82 ± 0.02 kg/day for F × J compared to 0.73 ± 0.02 kg/day for Jersey bull calves. Marketing age in the veal production system differed (P ith Jersey and F×J bull calves marketed at 7.1 ± 0.1 and 6.3 ± 0.1 months of age, respectively. End live weight at 21 months of age of Jersey and F × J differed (P ing 322.6 ± 13.4 and 441.4 ± 14.9 kg respectively. This was due to a higher (P ily gain in F × J vs. Jersey steers, i.e. 0.64 ± 0.02 and 0.46 ± 0.0 kg/day, respectively. Fleckvieh × Jersey steers had a higher (P ight at 21 months of age being 206.5 ± 8.9 kg vs. 157.9 ± 8.6 kg respectively. These results indicated the potential of improving beef production characteristics of the Jersey cattle through crossbreeding.

T-condylar fracture delayed for 10 days in a 5-year-old boy： a case report and review of the literature

引用

Chinese Journal of Traumatology 2013年第1期16卷 58-60页

作者： Shashidhar B Kantharajanna Vijay goni Pebam Sudesh Nirmal Raj Gopinathan Department of Orthopaedics Post Graduate Instituteof Medical Education and Research Chandigarh India

T-condylar fracture is rare in paediatric age group, especially in skeletally immature children less than 9 years old. with very few cases reported in available literature. We present such a case in a 5 year old child that was initially managed as a supracondylar fracture at another centre before referral to us, 10 days after the injury. The child was diagnosed as having a displaced T-condylar fracture on plain radiograph. Open reduction and internal fixation with K-wires was performed. At 2 years follow-up, the child had good range of motion at elbow with 5°of cubitus varus. With this background we discuss the pertinent principles of management ofT-condylar fractures in skeletally immature children.
