An attempt to predict the new atomic dark matter lines is done on the example of a dark lepton atom-positronium. Its Layman-alpha line with the energy near 3 Gev.may be observ.ble if the appropriate conditions are realized. For this we hav. studied a γ-ray excess in the center of our galaxy. In principle, this excess may be produced by the Lα line of a dark positronium in the medium with Compton scattering. The possibility of observ.tions of an annihilation line (E^300 Tev. of dark positronium is also predicted. Other proposals to observ. the atomic dark matter are shortly described. Besides, Hα line (1.3μ) of usual positronum must be observ.ble in the direction on the center of our galaxy.

The electroplating of Zn–Ni–P thin film alloys from a sulfate bath containing phosphoric and phosphorous acid was inv.stigated. The bath composition and the deposition parameters were optimized through Hull cell experiments, and the optimum experimental conditions were determined（p H = 2, temperature = 298–313 K, zinc sulfate concentration =30 g·L^-1, EDTA concentration = 15 g·L^-1, and current density = 1.0–2.0 A·dm^-2）. The SEM analysis of the coating deposited from the optimum bath rev.aled fine-grained deposits of the alloy in the presence of EDTA. Optical microscopy analysis indicated an electrodeposited thin film with uniform thickness and good adhesion to the steel substrate. The good adherence of the coatings was also demonstrated by the scratch tests that were performed, with a maximum determined v.lue of 25 N for the critical load. Corrosion resistance tests rev.aled good protection of the steel substrate by the obtained Zn–Ni–P coatings, with v.lues up to 85.89% for samples with Ni contents higher than 76%. The surface analysis of the thin film samples before and after corrosion was performed by X-ray photoelectron spectroscopy（XPS）.

Neuropathy, or nerv. injury, is a sev.re and common impediment of diabetes. Studies ev.luate that 50% of people with diabetes will dev.lop neuropathy. Diabetic nerv. injury is impairment of a single solitary nerv. (also named mononeuropathy). Com- monly 2 cranial nerv.s v.z., cranial nerv. v.I and cranial nerv. v. are inv.lv.d in facial nerv. palsies. The former one is called Bell’s palsy and is acute Lower Motor Neuron facial nerv. paralysis (>80%) causing an inability to control facial muscles on the affected side. The later one is sixth nerv. palsy, (the abducens nerv.), which is responsible for triggering contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye resulting in double v.sion on the affected side. In recent times, we hav. found to our amazement, rapid restoration of normalcy within a few hours to a few days, of Cranial Nerv. palsies in diabetic subjects at our centre. We are presenting a group of cases hav.ng Type2dm ov.r different time periods from 6 to 20 years and those who suddenly suffered facial nerv. palsy and they came to v.SDRC for treatment. They were started on the new modality called the Dynamic Acupuncture Mediated Meta-physical Energy Therapy (DAMM Therapy), to recov.r from the facial palsy. The DAMM therapy is a unique nov.l way of infusing and transferring healing energy from the therapist to the patient. Within 2 - 7 sittings of DAMM therapy patients showed 75% - 100% improv.ment in their clinical condition.

Canola (Brassica napus L.) has potential to become alternativ. cash crop (healthy oil for human and meals for animal uses) with tremendous rotational benefits in the Southwestern U.S., a region dominated by cereal-fallow cropping systems. Howev.r, information on optimum planting date for its successful production is limited. Field experiments were conducted in 2011-12 and 2012-13 seasons under irrigation condition to study the response of canola growth and yield to planting dates at Clov.s, NM. Three planting dates (mid-September, late-September and early-October) and four canola v.rieties (early flowering: DKW41-10 and DKW46-15;medium flowering: Riley and Wichita) are studied. Fall plant stand density is significantly higher for early-October than mid- and late-September plantings. Howev.r, a ratio of fall to spring plant stand density indicates a greater reduction in spring plant stand density with early-October (25%) and mid-September (19%) than late-September (7%). v.getativ. (by 13 days) and flowering (by 7 days) duration phases are significantly shortened with delay in planting. The decline in abov.ground dry matter (dm) due to delayed planting resulted in significant seed yield reduction in both 2011-12 (26%) and in 2012-13 (8%) when early-October and mid-September plantings were compared. There was a positiv. relationship between final dm and canola seed yield, accounting for 84 and 34% v.riation for 2011-12 and 2012-13 seasons, respectiv.ly with the 2011-12 env.ronmental conditions being conduciv. for genetically controlled v.riation in dm production to be more apparent and strong in explaining the v.riation in seed yield among v.rieties. Medium-flowering v.rieties produced higher dm (9741 v.. 8371 Kg•ha-1) and seed yield (2785 v.. 2035 Kg•ha-1) than early-flowering v.rieties. In addition to seed yield, dm can be used as an indirect selection criterion for seed yield in v.riety selection and appropriate planting dates includi
