Effect of Chop Length and Level of Molasses on Chemical Composition of Yellow Corn Stover Silage

This factorial study was carried out from 15/10/2020 to 31/6/2021 to investigate the effect of chop length (CL) and level of molasses (M) added at ensiling on chemical composition of yellow corn stover including leaves and stems. Those materials were chopped into 4 lengths, 5, 10, 15 and 20 mm and molasses was added as a source of soluble carbohydrates at 3 levels, 6, 8 and 10% of dry matter (DM). Urea was added to all samples at 2% to enhance nitrogen content. Samples of ensiled materials were packed in double plastic bags and preserved for 60 days. Results revealed that there was a significant (P˂0.01) increase in DM content with increasing CL and level of M, and a significant (P˂0.05) increase in crude protein (CP) content with increasing level of M. Ether extract content was significantly (P˂0.05) decreased with increasing CL but (P˂0.01) increased with increasing level of M. Regarding cell wall components, neutral and acid detergent fibers (NDF, ADF) and cellulose contents were significantly (P˂0.01) decreased in silage samples prepared at fine CL. Lower (P˂0.01) NDF and cellulose contents were associated with those prepared with addition of M at 10%. In general, it was concluded that better results were achieved when samples of yellow corn stover silages including leaves and stems were prepared at 5 mm of chop length and addition of molasses at 10%. &nbsp

Imaging magnetic vortex configurations in ferromagnetic nanotubes

We image the remnant magnetization configurations of CoFeB and permalloy nanotubes (NTs) using x-ray magnetic circular dichroism photo-emission electron microscopy. The images provide direct evidence for flux-closure configurations, including a global vortex state, in which magnetization points circumferentially around the NT axis. Furthermore, micromagnetic simulations predict and measurements confirm that vortex states can be programmed as the equilibrium remnant magnetization configurations by reducing the NT aspect ratio.Comment: 14 pages, 4 figures, link to supplementary informatio

Autologous blood injection technique in the treatment of refractory lateral elbow tendinopathy

Background: Lateral elbow tendinopathy is a very common clinical condition whose management by the consultant often shifts from one to another modality. This study was conducted to know the efficacy of a minimally invasive technique of autologous blood injection in patients who were resistant to more conservative methods.Methods: This is a randomized prospective study of forty-eight patients (median age, 37 to 40 years), presenting with lateral elbow symptoms for a duration of more than six weeks and failed to respond to other methods of conservative treatment. Patients were consecutively grouped into treatment with autologous blood injections (Group I, n = 24) and control group with injection of normal saline (Group II, n = 24). 1 ml of autologous blood was drawn from dorsal venous arch and injected into the site of maximum tenderness over lateral aspect of the elbow under all aseptic precautions for all patients in group I. Similarly 1 ml of normal saline was injected at the site of maximum tenderness for patients in group II.  Results were evaluated based on severity of the elbow complaints, tenderness and Cozen’s test at the end of follow-up of twenty weeks.Results: The incidence of this condition was more in the third decade 39.6% (n=19), with female preponderance 58.3% (n=28) and the dominant arm being more commonly involved 58.3% (n=28). Excellent results were found in group I in n=15 (62.5%) whereas poor results were more in group II in n=14 (58.3%). Group I had poor result only in n=03 (12.5%) of patients who later were given another dose of autologous blood or were treated surgically. Conclusions: Injection of autologous blood is a very efficacious minimally invasive procedure with satisfactory results in patients of lateral elbow tendinopathy who do not respond to other conservative methods of treatment

Closed diaphyseal fractures of femur in children treated by hip spica: early result of a clinical study

Background: Diaphyseal fracture of femur is a common injury in children with bimodal age distribution. The treatment modality of these fractures depend on several factors such as age of the patient, characteristics of the fracture– degree of displacement, location of fracture in femur, comminution, and open or closed injury. With the invention of titanium elastic nails, the recent trend in treating these fractures is by closed reduction and TENS, but the surgical management is not without complications hence we share our experience to reemphasize the role of hip spica cast immobilisation in treating these injuries.Methods: This is a prospective study of 30 cases of diaphyseal fractures of femur in children between the ages of 6 month to 6 years. History and mode of injury were recorded and complete physical examination was done. Plain anteroposterior and lateral radiographs confirmed diagnosis. Hip spica cast was applied under sedation or short general anesthesia. One and half spica was applied over thick padding with hip flexed 45 degrees abducted 30 degrees and external rotation of 10 degree. No attempt was made to obtain an end to end reduction. Patients were allowed to go home the same day after giving instructions regarding spica care. Follow up was done and radiographs were taken at 1, 2, 4 and 12 weeks. Any malunion– LLD, angulation or rotation were recorded.Results: The mean age of patients was 3.5 years (range 0.5 to 6 years). Of these 12 (40%) were male and 18 (60%) were female. The commonest mode of injury was fall while play in 73.33% (n=22) of patients. Mid shaft fractures are more common 53.33% (n=16) followed by upper third 40% (n=12). Average time for fracture union was 6 weeks (range 4-10 weeks). At one year all fractures healed in a satisfactory position without any LLD. Two patients had minor skin problems which were easily treated and cast continued. No stiffness of hip, knee or ankle was noted. Conclusions: Hip spica casting is an effective and reliable method for treating femoral shaft fractures in children with a union rate of 100%. The advantages of conservative treatment such as the avoidance of general anaesthesia on two occasions and the avoidance of surgery make a compelling argument in favour of this form of treatment

The strength of nuclear shell effects at N=126 in the r-process region

We have investigated nuclear shell effects across the magic number N=126 in the region of the r-process path. Microscopic calculations have been performed using the relativistic Hartree-Bogoliubov approach within the framework of the RMF theory for isotopic chains of rare-earth nuclei in the r-process region. The Lagrangian model NL-SV1 with the inclusion of the vector self-coupling of omega meson has been employed. The RMF results show that the shell effects at N=126 remain strong and exhibit only a slight reduction in the strength in going from the r-process path to the neutron drip line. This is in striking contrast to a systematic weakening of the shell effects at N=82 in the r-process region predicted earlier in the similar approach. In comparison the shell effects with microscopic-macroscopic mass formulae show a near constancy of shell gaps leading to strong shell effects in the region of r-process path to the drip line. A recent analysis of solar-system r-process abundances in a prompt supernova explosion model using various mass formulae including the recently introduced mass tables based upon HFB approach shows that whilst mass formulae with weak shell effects at N=126 give rise to a spread and an overproduction of nuclides near the third abundance peak at A~190, mass tables with droplet models showing stronger shell effects are able to reproduce the abundance features near the third peak appropriately. In comparison, several analyses of the second r-process peak at A~130 have required weakened shell effects at N=82. Our predictions in the RMF theory with NL-SV1, which exhibit weaker shell effects at N=82 and stronger one at N=126 in the r-process region, support the conjecture that a different nature of the shell effects at the magic numbers may be at play in r-process nucleosynthesis of heavy nuclei.Comment: 14 pages, 8 figures; submitted to Physical Review C.
