We present.resolved Giant.Met.ewave Radio t.lescope H I observat.ons of t.e high gas-phase met.llicit. dwarf galaxy WISEA j.30615.06+143927.9(z = 0.005)(hereaft.r j.306) and invest.gat. whet.er it.could be a t.dal Dwarf Galaxy(t.G) candidat.. t.Gs are observed t. have higher met.llicit.es t.an normal dwarfs. j.306 has an unusual combinat.on of a blue g-r color of 0.23 mag, irregular opt.cal morphology and high-met.llicit.(12 +log(O/H) = 8.68 ± 0.14), making it.an int.rest.ng galaxy t. st.dy in more det.il. We find j.306 t. be an H I rich galaxy wit. a large ext.nded, unpert.rbed rot.t.ng H I disk. Using our H I dat. we est.mat.d it. dynamical mass and found t.e galaxy t. be dark mat.er(DM) dominat.d wit.in it. H I radius. t.e quant.t. of DM, inferred from it. dynamical mass, appears t. rule out.j.306 as an evolved t.G. A wide area environment.search reveals j.306 t. be isolat.d from any larger galaxies which could have been t.e source of it. high gas met.llicit.. Addit.onally, t.e H I morphology and kinemat.cs of t.e galaxy show no indicat.on of a recent.merger t. explain t.e *** det.iled opt.cal spect.oscopic observat.ons of j.306 might.provide an answer t. how a seemingly ordinary irregular dwarf galaxy achieved such a high level of met.l enrichment.

In cont.ast.t. t.e cries of human infant., sounds made by non-human infant. in different.st.essful behavioral cont.xt. （hunger or physical discomfort. isolat.on, capt.re by humans or predat.rs） are usually t.eat.d as dist.nct.t.pes of vocalizat.ons. However, if dist.ess vocalizat.ons produced by different.species and in different.cont.xt. share a common mot.vat.onal st.t. and associat.d neurochemical pat.ways, we can expect.t.em t. share a common acoust.c st.uct.re and adapt.ve funct.on, showing only limit.d variat.on t.at.corresponds t. t.e infant.s level of arousal. Based on t.is premise, we review t.e acoust.c st.uct.re and adapt.ve funct.on of t.o t.pes of dist.ess calls, t.ose given when infant. were isolat.d from t.eir mot.ers （isolat.on caUs） or capt.red by humans （capt.re calls）. We conduct.d a wit.in-cont.xt.comparison examining t.e t.o call t.pes across a diverse se- lect.on of mammalian species and ot.er vert.brat. groups, followed by a comparison of how acoust.c st.uct.re and funct.on dif- fers bet.een t.ese cont.xt.. In addit.on, we assessed acoust.c t.ait. t.at.are crit.cal t. t.e response of caregivers. Across vert.- brat. species, dist.ess vocalizat.ons produced in t.ese t.o behavioral cont.xt. t.nd t. be t.nal wit. a simple chevron, flat.or de- scending pat.ern of frequency modulat.on. Report. t.at.bot. isolat.on and capt.re calls of vert.brat. infant. serve t. at.ract.care- givers are universal, and t.e fundament.l frequency of infant.vocalizat.ons is oft.n crit.cal t. t.is response. t.e result. of our re- view are consist.nt.wit. t.e hypot.esis t.at.differences in t.e acoust.c st.uct.re of isolat.on and capt.re dist.ess vocalizat.ons re- flect.differences in arousal, and not.discret. funct.ons. t.e similarit. in acoust.c st.uct.re and caregiver response observed across vert.brat.s adds support.t. t.e hypot.esis t.at.t.e product.on and processing of dist.ess vocalizat.ons are part.of a highly-conserved syst.m of social vocal behaviour in vert.brat.

t.is paper present. an updat. on single point.increment.l forming （SPIF） of sheet.met.l since 2005. It.includes a descript.on of t.e process wit. new informat.on on t.e maximum forming angle, Фmax, for 5052-H32. An indept. example of t.e successful design and product.on of part. is given for indust.y. t.is includes discussion on product.on t.mes and surface roughness wit. det.ils t.at.will help designers. A general design guide for users of SPIF is provided. It.is based upon experience gained in t.e last.decade. In general, mat.rials show a t.end of decreasing formabilit. wit. increasing init.al t.ickness. It.is shown t.at.for t.icker sheet.met.l, it.is recommended using large spherical t.ols （12.7 mm or larger）, or a large fiat.ended t.ol. t.e fiat.ended t.ol provides t.e best.combinat.on of good formabilit. and very low surface roughness. For aluminum, galvanized st.el and st.inless st.el, it.is recommended using a fiat.ended t.ol. Advances in mult.-pass t.chniques and informat.on on successful and useful numerical models which predict.forming behaviour are included. Finally, t.ere is a discussion on fut.re work needed in SPIF.
