A wear-resistant flash tank pressure let down nozzle for use in passing an ore slurry into an ore slurry flash tank to release steam from the slurry and reduce the pressure of the slurry. The nozzle has an expansion cone flaring toward the discharge end of the nozzle. The cross-sectional area of a choke section of the nozzle and the exit diameter of the expansion cone are selected to establish a relationship between pressure upstream of the nozzle and pressure in the flash tank so that underflashing, overflashing, and shock waves inside the flash tank are minimized.
This invention relates to the release of pressure from oxidized ore slurry in an autoclave circuit. In particular, the invention relates to the design of a nozzle system through which ore slurry passes into slurry flash tanks.
Autoclave circuits are used to recover gold from refractory sulfidic ores. Ore leaving an autoclave is typically passed to a series of flash tanks where pressure is let down and steam is flashed off to cool the slurry, and reduce it to atmospheric pressure for further processing. Steam from each flash tank is recycled and contacted with autoclave feed slurry in a complementary splash condenser, operated at substantially the same pressure as the flash tank, for preheating the autoclave ore feed slurry. In one particular system the pressure from the autoclave slurry discharge is let down in two stages. In the first stage, pressure is let down from about 420 psig to about 120 psig. In the second stage, pressure is let down from about 120 psig to atmospheric. This second pressure drop corresponds to a much greater volume expansion than in the first stage.
Heretofore this second pressure drop from about 120 psig to atmospheric has been accomplished by use of a nozzle system comprising a straight tubular choke extending from outside the flash tank to inside the flash tank. The choke was surrounded by a ceramic lined blast tube extending further into to flash tank, as shown in FIG. 4. As the volume of the slurry expands rapidly upon passage through the choke, the blast tube was violently impacted with steam entrained with ore slurry. Catastrophic failure of the blast tube, resulting in ore slurry damaging and even breaching the low pressure flash tank, has occurred. The typical life of such nozzle systems, and in particular of the blast tubes, has been relatively short, for example, six weeks, depending on operating parameters, ore characteristics, and many other factors. Rebuilding and/or replacing such nozzle assemblies is expensive in terms of capital costs and in terms of process downtime.
Among the several objects of the invention, therefore, are the provision of an extended life nozzle system for a low pressure slurry flash tank; the provision of an improved apparatus for preheating gold ore slurry prior to pressure oxidation and for reducing the pressure of pressure oxidized gold ore slurry after pressure oxidation; and the provision of an improved process for reducing the pressure of pressure oxidized gold slurry.
Briefly, therefore, the invention is directed to a wear-resistant flash tank pressure let down nozzle for use in passing an ore slurry into an ore slurry flash tank to release steam from the slurry and reduce the pressure of the slurry. The nozzle has an inlet end, a discharge end, and a tubular passageway extending therebetween for passage of the slurry from a location outside the flash tank in fluid flow communication with the inlet end. The slurry passageway has a choke comprising a zone of the passageway in which its cross sectional area is smallest, the passageway flaring with respect to the axis thereof toward the discharge end to define an expansion cone. The cross-sectional area of the choke and the exit diameter of the expansion cone being selected to establish a relationship between pressure upstream of the nozzle and pressure in the flash tank so that shock waves inside the flash tank are weaker than shock waves inside a reference flash tank having identical dimensions and configuration and operating under identical conditions except having a reference pressure let down nozzle consisting of a straight choke.
The invention is also directed to an ore slurry flash tank apparatus for receiving and holding pressure oxidized ore slurry for reducing the pressure of pressure oxidized gold ore slurry. The apparatus has a vessel having a bottom, a top, and side walls, and a wear-resistant flash tank pressure let down nozzle. The nozzle has an inlet end, a discharge end, and a tubular passageway extending therebetween for passage of the slurry from a location outside the flash tank in fluid flow communication with the inlet end. The slurry passageway has a choke comprising a zone of the passageway in which its cross sectional area is smallest, the passageway flaring with respect to the axis thereof toward the discharge end to define an expansion cone. The cross-sectional area of the choke and the exit diameter of the expansion cone are selected to establish a relationship between pressure upstream of the nozzle and pressure in the flash tank so that shock waves inside the flash tank are weaker than shock waves inside a reference flash tank having identical dimensions and configuration and operating under identical conditions except having a reference pressure let down nozzle consisting of a straight choke.
In another aspect, the invention is directed to an apparatus for preheating gold ore slurry prior to pressure oxidation and for reducing the pressure of pressure oxidized gold ore slurry after pressure oxidation. There is a flash tank for receiving a volume of pressure oxidized gold ore slurry, the flash tank comprising a vessel having a bottom, a top, and side walls, and a nozzle on the top of the vessel for passing ore slurry into the vessel. The nozzle has an inlet end, a discharge end, and a tubular passageway extending therebetween for passage of the slurry from a location outside the flash tank in fluid flow communication with the inlet end. The slurry passageway has a choke comprising a zone of the passageway in which its cross sectional area is smallest, the passageway flaring with respect to the axis thereof toward the discharge end to define an expansion cone. The cross-sectional area of the choke and the exit diameter of the expansion cone are selected to establish a relationship between pressure upstream of the nozzle and pressure in the flash tank so that shock waves inside the flash tank are weaker than shock waves inside a reference flash tank having identical dimensions and configuration and operating under identical conditions except having a reference pressure let down nozzle consisting of a straight choke. There is a steam outlet for passing steam out of the flash tank, and a splash condenser for contacting ore slurry with steam prior to pressure oxidation of the ore slurry in order to preheat the ore slurry, the splash condenser having a steam inlet. There is also conduit for transferring steam from the steam outlet of the flash tank to the splash condenser.
The invention is further directed to a process for reducing the pressure of pressure oxidized ore slurry from above about 100 psig to about atmospheric. Slurry is passed through a nozzle into a flash tank, the nozzle disposed on the top of the flash tank and comprising a receiving end and a discharge end, and a slurry passageway extending through the nozzle from the receiving end to the discharge end for passage of the slurry into the flash tank from a location outside the flash tank. The slurry passageway flares outwardly at an angle of about 15° toward the discharge end to gradually reduce the pressure of the slurry and to direct the slurry such that it impacts a volume of slurry in the bottom of the flash tank.
The invention is also directed to an ore slurry flash tank apparatus for receiving and holding pressure oxidized ore slurry for reducing the pressure of pressure oxidized gold ore slurry. There is a vessel having a bottom, a top, and side walls, and a nozzle on the top of the vessel for passing ore slurry into the vessel. The nozzle has an inlet end, a discharge end, and a tubular passageway extending therebetween for passage of the slurry from a location outside the flash tank in fluid flow communication with the inlet end. The slurry passageway comprises a choke comprising a zone of the passageway in which its cross sectional area is smallest, the passageway flaring with respect to the axis thereof toward the discharge end to define an expansion cone. The nozzle has a choke diameter of between about 31/2 and about 41/2 inches, an expansion cone exit diameter of between about 7 and about 71/2 inches, and an expansion cone length of between about 53/4 inches and about 61/4 inches, to establish a relationship between pressure upstream of the nozzle and pressure in the flash tank so that shock waves inside the flash tank are weaker than shock waves inside a reference flash tank operating under identical conditions except having a reference pressure let down nozzle comprising a straight choke.
In another aspect, the invention is directed to an ore slurry flash tank apparatus for receiving and holding pressure oxidized ore slurry for reducing the pressure of pressure oxidized gold ore slurry from between about 100 psig and about 140 psig to about atmospheric. There is a vessel having a bottom, a top, and side walls, and a nozzle on the top of the vessel for passing ore slurry into the vessel. The nozzle has a tubular passageway extending therebetween for passage of the slurry from a location outside the flash tank in fluid flow communication with the inlet end, the slurry passageway comprising a choke comprising a zone of the passageway in which its cross sectional area is smallest. The passageway flares with respect to the axis thereof toward the discharge end to define an expansion cone. The nozzle has a choke diameter of between about 3.8 and about 4.1 inches corresponding to the smallest cross-section in the slurry passageway, the straight section having a length of between about 91/2 and about 101/2 inches, an expansion cone exit diameter of between about 7.1 and about 7.4 inches, an expansion cone length of between about 6 inches and about 6.2 inches, and an expansion cone length of between about 14° and about 16°, to establish a relationship between pressure upstream of the nozzle and pressure in the flash tank so that shock waves inside the flash tank are weaker than shock waves inside a reference flash tank operating under identical conditions except having a reference pressure let down nozzle comprising a straight choke.
Other objects and features of the invention will be in part apparent and in part pointed out hereinafter.
FIG. 12 is a graph depicting kinetic power due to steam expansion.
FIG. 1 illustrates a preferred gold recovery process in which the invention is used. This process is described generally in Thomas et al. U.S. Pat. No. 5,071,477 and Thomas et al. U.S. Pat. No. 5,489,326, the entire disclosures of which are expressly incorporated by reference. According to such a process, ore is crushed and wet milled, and the ground ore slurry screened for trash or tramp material. The ground ore is thickened by removal of excess water in a solid-liquid separation operation. The ore slurry is then subjected to pressure oxidation in the presence of sulfuric acid using oxygen gas at elevated pressure. It is sometimes necessary to add sulfuric acid to facilitate oxidation, so the addition of sulfuric acid to the thickened ore slurry is indicated as an optional step. Pressure oxidation is typically conducted in a horizontal multi-compartmented autoclave, the compartments of which are preferably of substantially equal volume. Energy from the exothermic pressure oxidation is recovered by heat exchange between the oxidized slurry and acidulated feed to the autoclave. As indicated in FIG. 1, this heat exchange is preferably effected by letting down the pressure of the oxidized slurry in flash tanks in which the nozzles of the current invention are used, and using the steam which is flashed from the oxidized slurry to heat the autoclave feed, preferably by direct contact in splash condensers positioned ahead of the autoclave.
After it is partially cooled by flashing of steam, the oxidized slurry is further cooled and then passed directly to a neutralization operation. Here lime and/or other base is added to increase the pH to allow for subsequent cyanide leaching. Gold is recovered from the neutralized oxidized slurry by, for example, carbon-in-leach cyanidation in a continuous countercurrent system.
Referring to FIG. 2, ground ore slurry is directed to a trash screen 1; ore slurry passing through the screen is directed to a mechanical thickening device 2, typically a vertical tank of large diameter which provides a net vertical flow low enough to permit sedimentation of the solid particles. Overflow from the thickener is recycled to the grinding circuit. Thickened ore slurry underflow from the thickener is directed to another trash screen (not shown) and by a transfer pump 3 to a series of stirred acidulation tanks 5, 6 and 7, through which the slurry passes continuously. Although three stages are shown, in the preferred embodiment there are four stages. A fresh sulfuric acid stream (optional) 4 is added to the acidulation tanks in order to release carbon dioxide from the carbonate contained in the slurry, and thereby reduce the equivalent carbon dioxide levels in the ore. To promote removal of CO2, compressed air may be sparged into the acidulation tanks.
Residue slurry leaving the acidulation tanks is fed by a transfer pump 8 to the first of a series of brick lined splash condensers 9 and 10, in which the treated feed slurry for the pressure oxidation step is preheated by contact with steam flashed from the oxidized slurry leaving the pressure oxidation. The successive splash condensers are each, preferably, internally baffled to promote contact between steam and liquid, and are respectively operated at progressively higher pressure and temperature. A 2-stage centrifugal pump 12 is interposed to increase the pressure of the slurry between condensers.
Pressure oxidation is carried out in an autoclave 15, where the slurry is passed through a plurality of compartments to provide a retention time of the order of 50-80 minutes, where it is contacted in the presence of sulfuric acid with oxygen gas at a temperature of between about 185° and about 225° C., an oxygen partial pressure of at least about 25 psig and a total pressure of between about 215 and about 480 psig. The final acidity of the slurry leaving the last compartment of the autoclave is between 5 and 25 grams sulfuric acid per liter of solution, and the final emf of the slurry is between about 480 and about 530 mv.
Noncondensables and steam generated during the pressure oxidation operation are optionally vented through a scrubber. Oxidized slurry leaving the autoclave is passed to a series of flash tanks 17 and 18, through control valves 17a and 18a, respectively, and through nozzle assemblies 41 and 42. In the first flash tank the pressure of the slurry is let down from about 420 psig to about 120 psig. In the second flash tank the pressure of the slurry is let down from about 120 psig to about atmospheric. Steam from each flash tank is recycled and contacted with autoclave feed slurry in a complementary splash condenser, operated at substantially the same pressure as the flash tank, for preheating the feed slurry. Thus, in the series as illustrated in the drawing, the first flash tank 17 is coupled to the last splash condenser 10, and the second flash tank 18 is coupled with the first condenser 9.
The flash tanks are vessels of generally cylindrical shape having a dished bottom, a dished top, and parallel side walls. As shown in FIG. 6, the preferred flash tank has a slurry inlet 49, a steam outlet 48, a slurry outlet 51, a manhole 52 to permit inspection of the tank interior, a drain 53, and a blank outlet 54.
In the first flash tank, where the slurry pressure is let down from about 420 psig to about 120 psig, there is a volume expansion of the steam of from about 3 to about 3.5 times its volume at 420 psig. In the second flash tank, where the slurry pressure is let down from about 120 psig to about atmospheric, there is a volume expansion of the steam of from about 8.5 to about 9.5 times its volume at 120 psig, or on the order of 30 times its volume at 420 psig. With regard to the second flash tank, or low pressure flash tank, it is preferred that the total tank volume be between about 1.6 and about 1.9 times the volume of slurry it is to hold at any given time. In the preferred embodiment where the volume of slurry in the tank is generally maintained between about 9000 and about 10,000 gallons (U.S.), and the volume of the tank is about 16,500 gallons, this helps ensure a slurry depth adequate to receive and dissipate the energy of slurry as it enters the vessel and impacts the slurry surface.
Referring to FIG. 3, hot oxidized slurry from the flash tank 18 is transferred to an intermediate agitated storage tank 23. In order to condition the slurry for gold recovery operations, the temperature of the hot oxidized slurry is reduced to about 25 to 40° C. by passing the slurry, by means of pump 24, through a series of shell and tube coolers 25. The temperature of the slurry is reduced by exchanging heat from the slurry to a cooling water stream. Cooling water is obtained from a recirculating system in which the water is recycled through a crossflow, induced draft cooling tower 26 by pump 27.
Cooled oxidized slurry which is discharged from the coolers 25 is fed continuously through a series of rubber or epoxy lined agitated neutralization tanks 28, 29 and 30, where it is neutralized with a slurry of lime and/or other base to raise its pH to the neighborhood of 10 to 12. Compressed air 34 is optionally sparged into the slurry in the neutralization tanks to convert ferrous iron to ferric iron, as the former consumes cyanide in the subsequent carbon-in-leach operation. The neutralized slurry is then directed to a carbon-in-leach operation by transfer pump 31 where the gold in the oxidized slurry is recovered by, for example, conventional carbon-in-leach (C-I-L) cyanidation.
Turning now to FIGS. 4 and 5 there is shown a prior art nozzle assembly employed at location 42 of FIG. 2 from the second (low pressure) flash tank. The assembly consists of a straight choke 60 surrounded by a ceramic lined titanium blast tube 61. An impact zone is shown at 62 in FIG. 5 where the blast tube is impacted with steam entrained with ore slurry as it rapidly expands upon entering the flash tank.
FIGS. 6 and 7 show the nozzle of the invention, consisting of first and second opposite ends 44 and 45, respectively, and a steam/slurry passageway 46 extending through the nozzle from the first end 44 to the second end 45. The nozzle is constructed from a material having high hardness. One preferred material is a sintered alpha phase silicon carbide available from Carborundum (Amherst, N.Y.) under the trade designation Hexoloy SA.
Slurry and steam pass into the nozzle at the first end 44 and out of the nozzle at the second end 45 thereof to a location inside the flash tank. As shown in FIG. 7, the steam passageway flares outwardly from a location generally halfway through the passageway, axially inwardly of the second end toward the second end. FIG. 6 is a schematic representation--the actual nozzle configuration is more accurately portrayed in FIG. 7. In one preferred embodiment, the slurry flow rate through the nozzle is between about 100 tons per hour and about 500 tons per hour of ore slurry comprising between about 30% and about 70% solids by weight.
Important nozzle dimensions for the prediction and control of flashing behavior include the straight section or choke diameter, the expansion cone exit diameter, and either the expansion cone length or the expansion half-angle. By careful selection of these dimensions, it has been discovered that a relationship can be established between pressure upstream of the nozzle and pressure downstream of the nozzle, so that the development of shock waves just inside the nozzle exit, which resulted in excessive noise and vibration with prior designs, and internal wear can be minimized. In particular, the nozzle is designed so that the pressure at the discharge end is about the same as the pressure in the tank. The shock waves, noise and vibration are substantially reduced in comparison to a system operating under identical conditions (i.e., a "reference" flash tank), with the only difference being use of a straight choke flash tank nozzle (i.e., a "reference" nozzle). The shock waves inside the flash tank using the nozzle of the invention are weaker than shock waves inside a flash tank using a straight choke, but otherwise identical. Also, recondensation which occurred as a result of overflashing, which recondensation was deleterious to vapor-liquid separation within the flash tank, thereby causing excessive liquid and solids entrainment in the recycled steam to the preheat towers, can also be minimized.
The choke diameter fixes the slurry mass rate of flow entering the flash tank at a given absolute pressure (or, alternatively, fixes the upstream pressure at a given mass rate of flow) according to the equation: ##EQU1## where m is the mass rate of flow, At is the choke cross-sectional area, and the remainder of the equation is a unique function of absolute pressure within the choke. A derivation of this formula is presented below in Appendix A. In one preferred embodiment where the pressure is to be let down from between about 14° psia and about 100 psia to about atmospheric, and where the mass flow rate is from about 1500 to about 3000 tons/day solids (50% pulp density), by use of the analysis of the invention, the choke diameter is from about 2.8 inches to about 4.6 inches.
The expansion cone exit diameter largely fixes the absolute exit pressure of the flashing slurry upon entering the flash tank. It is important for this exit pressure to match closely the pressure within the flash tank, for they are generally not equivalent otherwise. In the preferred embodiment where the pressure is to be let down from between about 140 psia and about 100 psia to about atmospheric, and where the mass flow rate is from about 1500 to about 3000 tons/day solids (50% pulp density), by use of the analysis of the invention, the expansion cone exit diameter is from about 7.7 inches to about 11.5 inches. The expansion half-angle is between about 22° and about 30° where the choke diameter and expansion cone exit diameter are as described in this preferred embodiment. As alluded to above, if the exit pressure is too high (i.e., the nozzle does not reduce the pressure far enough), underflashing occurs, in which case a significant amount of flashing must occur beyond the nozzle. This results in a recirculating flow pattern which causes external wear to the nozzle casing. If the exit pressure is too low (i.e., the nozzle reduces the pressure too far), overflashing occurs, in which case a shock wave develops just inside the nozzle exit resulting in excessive noise and vibration, and possibly internal wear. Also, the recondensation which must occur as a result of the overflashing may be deleterious to vapor-liquid separation within the flash tank, thereby causing excessive liquid and solids entrainment in the recycled steam to the preheat towers.
The expansion cone length fixes the expansion half-angle for any given set of choke and exit diameters. It is important that the expansion cone be between ten and twenty centimeters (about four and eight inches) long. Shorter than 10 cm, and vapor-liquid equilibrium cannot be assumed during flashing. Longer than about 20 cm, and friction losses may become significant, thereby invalidating the assumption of isentropic flow. Either of these two situations limits the predictability of flashing, and are therefore to be avoided. Hence, the optimum length of the expansion cone is taken to be about 15 cm (6 in). In the case of the low-pressure flash tanks at Barrick Goldstrike, given the necessary choke and exit diameters, this results in an expansion half-angle of about 15°. This angle also has a very slight effect on exit pressure. However, once it is fixed, then the exit diameter may be chosen with confidence from the mathematical model of slurry flashing.
The graph of FIG. 11 illustrates predicted absolute pressure versus length within the existing low-pressure flash system at Barrick Goldstrike at the design solids flow rate. This graph shows how the target downstream pressure may be obtained within a certain expansion cone length, given a certain expansion half-angle. This graph depicts the optimum design for the low-pressure flash nozzle, with 8.4 bar (120 psi) absolute entrance pressure, and 0.8 bar (12 psi) absolute exit pressure.
Kinetic power due to steam expansion developed within the optimum design at the pressures shown in FIG. 11 is depicted in FIG. 12. Note that the kinetic power developed is only about half of a megawatt. This is approximately 8 times less than the original choke/blast-tube apparatus (which self-destructed).
In one preferred embodiment of the invention shown in FIG. 7 the straight section or choke diameter is between about 31/2 and about 41/2 inches, preferably between about 3.8 and 4.1 inches. The expansion cone exit diameter is between about 7 and about 71/2 inches, preferably between about 7.1 and 7.4 inches. The expansion cone length is between about 53/4 inches and about 61/4 inches, preferably between about 6 and 6.2 inches. The expansion half-angle is between about 12° and about 18°, preferably between about 14° and about 16°. The straight section has a length of between about 8 inches and about 12 inches, more preferably between about 91/2 inches and about 101/2 inches.
A nozzle as described above and shown in FIG. 7 was made from Hexoloy SA available from Carborundum. The nozzle had an inner diameter of 4 inches in the first upper segment, and upper segment length of 10 inches, a lower segment length of 6.1 inches, the lower segment flaring at an angle of 15° from an inner diameter of 4 inches to an inner diameter of 7.25 inches. This nozzle was installed in a low pressure flash tank for reducing slurry pressure from about 120 psig to about atmospheric pressure. The nozzle was installed without a blast tube. After 30 weeks, even without a blast tube, no significant wear was visible on the nozzle nor on the flash tank vessel walls.
As various changes could be made in the above embodiments without departing from the scope of the invention, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.
1. Homogeneous flow--vapor, liquid, and solid phases are flowing at the same velocity at any point within the system.
2. Vapor-liquid equilibrium--flashing occurs via a known thermodynamic path.
3. Isentropic flow--the slurry loses no energy to friction.
4. Adiabatic flow--the slurry gains no heat, and does no work.
5. Solid-fluid thermal equilibrium--all phases at a uniform temperature at any point within the system.
Homogeneous flow theory provides the simplest technique for analyzing multiphase flows, and can be fairly accurate so long as the phases are intimately mixed, which is the case in flashing slurries. The assumption of vapor-liquid equilibrium is more troublesome. It is known that rapid acceleration and pressure changes render equilibrium theory inaccurate for describing the discharge of flashing steam-water mixtures through orifices, making it necessary to consider the rates of bubble nucleation and growth in the superheated liquid. However, controlled expansion through nozzles as short as 10 cm can be predicted with surprising accuracy.
In flashing flow through nozzles, pressure drops are generally very large, and thus friction becomes an insignificant source of entropy. Furthermore, in the absence of heat sources or turbines, the adiabatic assumption can be safely made. Finally, the rate of heat transfer from finely ground solids can be safely assumed high enough to ensure thermal equilibrium between the solid and fluid phases.
The basic equations for steady one-dimensional homogeneous equilibrium flow in a duct are: ##EQU2## where m is the slurry mass rate of flow, ρ and v are the slurry density and specific volume, u is velocity, A and P are the duct cross-sectional area and perimeter, τw is the average wall shear stress, dq/dz and dw/dz are the rate of heat input and work output per unit length of duct, respectively, z is the vertical coordinate, and θ is the angle of inclination of the duct to the vertical. Either ρ or 1/v may be used to express slurry density. For our purposes, v is more convenient.
The choking condition is thus: ##EQU22## where M is the Mach number. Hence, the critical slurry mass rate of flow is determined by: ##EQU23## where the subscript t denotes conditions in the "throat" or narrowest section of the choke. Finally, combining equations (16) and (19) results in the final expression for steam quality gradient: ##EQU24## Equations (24) and (27) are the working equations of the model. With a given choke or nozzle profile and the steam tables, these two equations may be integrated numerically to determine the critical slurry mass rate of flow, and the corresponding fluid properties, anywhere in the nozzle.

            ps_SOFVDISN.setString(6, beanItem.getNotaFiscalRef().getSerNfRef());
            ps_SOFVDISN.setString(7, beanItem.getNotaFiscalRef().getNumNfRef());
            ps_SOFVDISN.setString(8, "");
            ps_SOFVDISN.setString(9, "");
            ps_SOFVDISN.setString(10, beanItem.getNotaFiscalRef().getCgcEstbRef());
            ps_SOFVDISN.setString(11, beanItem.getNotaFiscalRef().getQtdUsadaReferencia());

            if (beanItem.getNotaFiscalRef().getSerNfRef() != null && !beanItem.getNotaFiscalRef().getSerNfRef().trim().equals("")
                || beanItem.getNotaFiscalRef().getNumNfRef() != null && !beanItem.getNotaFiscalRef().getNumNfRef().trim().equals("")
                || beanItem.getNotaFiscalRef().getCgcEstbRef() != null && !beanItem.getNotaFiscalRef().getCgcEstbRef().trim().equals("")
                || beanItem.getNotaFiscalRef().getQtdUsadaReferencia() != null &&
                !beanItem.getNotaFiscalRef().getQtdUsadaReferencia().trim().equals("") && !beanItem.getNotaFiscalRef().getQtdUsadaReferencia().equals(" "))
            {

                if (ps_SOFVDISN.executeUpdate() == 1) {
                    System.out.println("Sucess - Insert ok");
                    retornoResult = true;
                }
            }

A: and what about adding not null constraint in database for columns, which user must define?

A: Outside of adding null constraints, you can use the ternary operator to check if those fields are null or empty before setting them.
ps_SOFVDISN.setString(6, !beanItem.getNotaFiscalRef().getSerNfRef().isEmpty() ? beanItem.getNotaFiscalRef().getSerNfRef() : "");

A: Look into either DB Constraints or Java bean validation frameworks. You want to validate your data before allowing it into your DB.
Generally, I would recommend one of these 3 options in this order to handle your validation:

*

*Use the DB Constraints (Easy to do, Guaranteed, Good for many simple use cases)

*Use a framework (Good for complex use cases)

*Write validation yourself to kick out before INSERT

There are more pros and cons to each approach, but too much to get into here.

In PHP, if you want to make use of a library written in C, you generally have to go and write a new PHP extension. This isn't that hard if you've done it before, but it does require a bit of work and some getting used to. There's also a fair bit of boilerplate code that is required to create functions, classes, and methods, and to handle parameter parsing. The documentation for this side of things isn't that great right now, though there are efforts to change this. One advantage is that there are quite a number of people who have done it before, and you can use tools like PHP's OpenGrok to find examples and inspiration.
It would be nice to make this sort of thing simpler to do. Perhaps, we could avoid having to write any C code. As I mentioned in my previous post, there are other tools in the works to make accelerating code written in PHP faster. I mentioned Anthony Ferrara's Recki-CT, which takes PHP code and accelerates that. There is also the Zephir project which takes code written in a PHP-like language and can create extensions for you from that.
Both of these require a bit of time to set up and operate, though. They're also not really aimed at using existing libraries – their goal is to accelerate self-contained high-level code rather than to provide access to lower-level libraries.
Some languages have a feature that allows the user to load C shared libraries and call functions from them in the same way you'd call any other function in that language. These are known as foreign function interfaces. Python has a number of these – ctypes is one example, and CFFI is another. Similarly, Ruby has the FFI library. Many other languages possess these. There has been one for PHP for a while, called ext/ffi, but it hasn't had a release in a number of years.
I decided it sounded like an interesting project, so I would like to present to the world MFFI.
It's a fairly new extension, so currently it doesn't have that many features. One thing it can do at the moment is handle custom C structs. You can see this in the code below.
It gets a spare trailing newline, but it looks pretty good on the whole.
You can also write your own libraries and use those. Here's a bit of C code that provides a function that reverses strings. It's trivial, and PHP already provides this, but it's just an example. The strrev function in the code accepts a string (as a char *), and returns another string (again a char *).
This is probably a very, very bad idea. The potential for security problems is monumental. If you get a definition even slightly wrong, you'll either crash PHP straight away, which is probably the best result, or corrupt some memory somewhere and have unseen and weird effects. I would never advise anyone to use it unless it was a one-shot script or something running in a very controlled, non-public facing environment. If you use this, and it breaks, you get to keep all the bits!
This extension is only for PHP 7. It doesn't work on PHP 5, and I don't intend to change that. There's a fairly big TODO list of features I want to add. I want to make it possible to define structs that contain other structs, which is a work in progress, and then handle large arrays of scalar types. This would make it possible to solve the Mandelbrot problem from the previous post fairly efficiently using a small C library that did the maths, without knowing anything about how to write PHP extensions.
I have not done any benchmarking yet. The translation through libffi will have a cost, but I have not yet worked out what that will be.

Who was going to pull the trigger first, we wondered, when we heard about the NCAA's approval of living stipends for DI student-athletes.
Erin noted the Title IX implications. But would schools and leagues realize them? Would a school be bullied into providing the stipends by its league? Would scholarship dollars grow further out of whack?
I think I assumed, given the recent upsurge in the pay-for-play debate spurred by Taylor Branch's Atlantic article, that football would take advantage of the new rule first.

Tesla smashed expectations with its most recent quarterly earnings report, turning a profit for only the 3rd time in its history.
Still, Wall Street has noticed that a bunch of the numbers leave more questions about how Tesla got there.
Plus, Tesla's plans for the future are very ambitious. Even with this influx of cash, investors are wondering how it's going to meet its goals without raising more cash.
Earlier this month Tesla blew its third-quarter earnings out of the water.
As CEO Elon Musk promised, for the third time in the company's history it posted a profit.
Net income was $311.5 million.
Revenue hit $6.8 billion, up 70% from the previous quarter.
And, perhaps most importantly, the company generated $881 million in free cash flow.
Musk promised that these numbers indicate the start of a new era at Tesla – an era in which the company would be profitable every quarter. That promise has Wall Street picking through the numbers to see if perennial profitability is possible for a company that has yet to turn an annual profit.
And Tesla's balance sheet leaves many reasons to be skeptical. With its $7.9 billion in assets still swallowed by $9.7 billion in liabilities; with a massive debt bill coming due in March; and with commitments to start all kinds of capital-intensive projects floating around, Tesla will need a lot of money.
What's more, on Wall Street, accounting is as much an art as it is a science. A really talented numbers-smith can make a smash hit out of a quarter that might otherwise have sounded sound like a flop. You just have to pay really close attention to what's really music, and what's just noise.
Now for the noise in Tesla's quarterly report.
First and most simply, Tesla got what UBS called "some unexpected help" by selling $137.2 million in non-ZEV regulatory credits to traditional automakers. It also sold $52.3 million in ZEV credits, bringing its total profits due to credits up to $189.5 million.
Tesla also went incredibly lean for the quarter. Research and development fell from 11% of sales to 5%, despite the fact that Musk has said that a Tesla Roadster, a Semi, a Model Y, and a pickup truck are in the works. Tesla also lowered the cash it keeps on hand for warranties from $2,913 per car in Q2 to $2,249 per car in Q3, according to UBS.
As of September 30, 2018, one entity represented 10% or more of our total accounts receivable balance. As of December 31, 2017, no entity represented 10% of our total accounts receivable balance.
A Tesla spokesperson said the quarter ended on a Sunday and said that entity is one of Tesla's partner banks, which had issued a large receivable to Tesla for customer loans for cars delivered over the weekend. That cash was then distributed during the first few days of Q4.
One investor pointed out to Business Insider that if you add that $72.8 million back to finished-goods inventory, Tesla's Q3 finished goods would be $8 million higher than its Q2 finished goods inventory. In Q2, finished goods hit about $1.72 billion. In Q3 (with the add back), it's about $1.73 billion.
This is odd because Tesla delivered more cars than it produced in Q3, so the number of finished goods on its books should decline compared to the quarter before.
All of these questions are about the past – about what happened in Q3 – but Tesla's balance sheet also leaves questions about its future. The company said it expects capital expenditures to come in just under $2.5 billion in 2018 and between $2.5 billion to $3.0 billion annually for 2019 and 2020.
And, of course, there are all the new models Tesla wants to build (mentioned above).
These are pretty ambitious plans for relatively flat capital expenditures, especially while Panasonic, the company that makes Tesla's batteries, told investors on its Q3 call that it's seeing major US tariff risks ahead that could jack up prices. Tesla has $3 billion in cash, but it also has $3.5 billion in accounts payable.
In other words, to invest heavily in its expansion, Tesla still needs to generate even more cash than it has. The company says its cash levels should remain pretty flat over the next year or two, though.
And, of course, there's the $920 million debt payment it needs to make in March.
This doesn't have to stop Tesla by any means. Musk can go raise some money from investors, but he's said repeatedly that he won't do that.
Which brings us to another, final question: Why not?

New app enables hearing-impaired taxi drivers in South Korea
Sun Apr 21, 2019 02:34PM [Updated: Sun Apr 21, 2019 02:39PM ]
A software program has made it possible for hearing-impaired taxi drivers to take to roads in Seoul, the capital of South Korea.
Lee Dae-ho became one of the first deaf taxi drivers in the city last year. Lee has profound hearing loss and cannot hear even when using hearing aids.
The communication-aiding technology developed by a local start-up called Coactus has been of great help to drivers like Lee.
To ensure clear communication between the driver and the passengers, two tablets are installed in the taxi: one facing the back seat, and the other next to the driver. Passengers can indicate their required destinations by speaking, writing or typing the information using the interface.
Each tablet has the "Goyohan Taxi" application installed, and "Goyohan" in the Korean language translates to "silent" in English.
The technology helps ease passengers' concerns that a driver's inability to hear may pose a safety risk on the busy roads of Seoul.
"I was very nervous when I got on the taxi, but later I found he is more focused on driving than ordinary drivers. When I was thinking about how can I tell the driver that I wanted to get off, the tablet gave an audio cue and then I got off. There is no difference from other taxis," said a passenger.
Support equipment for safe driving, including microphone sensing unit for distance, is also installed on the taxi. The equipment can recognize sirens of police car, ambulance and firefighting truck and transmits the information through both images and vibrations on steering wheel.
"The equipment can reduce sensory stress and fatigue of people with hearing impairments and identify different sounds accurately," said Lee Hyung-hyun, researcher with Hyundai Motor.

Слово дестабілізація може застосовуватися до найрізноманітніших контекстів, наприклад як спроби підірвати політичну, військову чи економічну владу.

Психологія
У психологічному контексті поняття використовується як метод промивання мозку та зловживань для дезорієнтації та роззброєння жертви.

У контексті знущань на робочому місці дестабілізація, застосована до жертви, може включати:

 нездатність визнати хорошу роботу та оцінити зусилля жертви
 розподіл безглуздих завдань
 усунення зон відповідальності без консультації
 неодноразові нагадування про грубі помилки
 налаштування на невдачу
 зміщення цілей завдання, не повідомляючи жертві
 наполегливі спроби деморалізувати жертву

Дестабілізація також може означати крайній кінець синдрому дезінгібіції та спричинити повне припинення контролю людини над емоціями, загальмованістю та продуктивним функціонуванням.  Захворювання може бути епізодичним або тривати місяцями або роками, що вимагає професійної допомоги від лікаря, який знайомий з первинним неврологічним розладом.

У психології також існує процес, який називається когнітивною дестабілізацією, який передбачає відкритість для змін стану та перетворень різного роду.  Цей термін може бути використано для протидії політичній дестабілізації шляхом подання узгодженого погляду на проблему..

Інші застосування
Дестабілізація також використовується в феміністичному контексті, наприклад, вона використовується для зміни двійкового протиставлення між чоловіками та жінками, зокрема, як надається категорії "жінка" свій сенс..  Наприклад, це виражається в дискомфорті багатьох феміністок у зв'язку з викликом постмодерністських теорій традиційних двійкових протиставлень, сприймаючи це як підрив спроби жінок визначити свою власну суб'єктність.  В літературі по фемінізму також часто згадується необхідність дестабілізувати сучасну теорію, особливо теоретичні дискурси, які претендують на нейтралітет, але встановлюються з чоловічої точки зору.  Ці спроби дестабілізувати сучасні жіночі конструкції були пояснені теорією деконструкції Жака Дерріди, зокрема дестабілізацією позицій та об'єктів, які були визнані цілісними чи авторитетними.

У літературі це поняття позначає агресію або свого роду напад на читача, щоб спровокувати дискомфорт.  У міжнародних операціях з капіталом поняття використовується для позначення руху капіталу, зумовленого помилковим прогнозом, зрухуючи обмінний курс від рівноваги, що було б підтримано раціональними спекулянтами, передбачення яких правильні.

My new venture of setting up my own business has well and truly begun. This is now month number 3. Things are going very slowly and I'm trying hard to stay positive, it is still early days. Waiting for the phone to ring is very frustrating and I have a new found respect for Postmen after enountering some extremely vicious letter boxes when delivering fliers. Fingers crossed business picks up soon.


What does rank have to do with it?
The Department of Defense relocates more families than any other organization in the United States. At that scale, the process can sometimes feel overwhelming - but you have choices regarding how you move. Do not hesitate to reach out to the local personal property office or the family support center at your current installation for help. Another amazing resource is MilitaryOne Source - they have representatives available 24/7 to answer those late night questions about your upcoming move.
Just Remember: Moving is never easy, but you will get through it.
In general, your moving process will start with the job/travel orders you receive from your service. In your orders, information describing your rank, the duration of your job/training, and your assigned location will determine if your entire dependent family can come, what you are allowed to bring, and how those items will arrive to your new location. If you have any questions, your local personal property office is the place to go for help deciphering your orders as they pertain to moving.
Permanent Change of Station (PCS) is when you are assigned to a location for 20+ weeks, regardless of whether your assignment pertains to training or a new job. In these circumstances, you should be allowed a full household move should you choose to take it.
Temporary Duty (TDY) is when you are temporarily assigned to a new location, for an extended period of time (over 31 days), but generally less than 20 weeks. For TDY, it is common that only a small subset of your household belongings will be able to travel with you to your new location.
When you are moving for a Permanent Change of Station (PCS) or a Temporary Duty (TDY) with the military, the way your household goods get transported from "Point A" to "Point B" largely depends whether your entire move will happen within the 48 contiguous US states or internationally (includes Alaska & Hawaii).
CONUS are moves that start and end within the 48 contiguous states of the US. Most moves in the US Military are CONUS moves.
Moves to or from Alaska and Hawaii along with international stations are considered OCONUS moves. These moves are more complicated and each location may have additional limitations on what you are allowed to transport.
Once you have figured out the type of move (PCS or TDY) and your move location (CONUS or OCONUS), you will have some choices to make regarding how your belongings are shipped to your new destination. Remember, you can split up your total allowable weight into multiple shipments. For example, most service members doing a PCS CONUS move will have both a PPM (Personally-Procured Move or "do it yourself") shipment of their prized, valuable possessions and an HHG ("Household Goods") shipment using a government-furnished moving company for the bulk of their belongings.
If you have any questions, your local personal property office is the place to go for help figuring out how to break up your weight into various shipments.
A Household Goods "HHG" move is a move completed by a government-furnished moving company, also called a Transportation Service Provider (TSP). During a HHG move, your transporter is responsible for packing all of your belongings and transporting them to your new location. If anything becomes lost or broken during your move, you can work with your transporter or the Military Claims Office to receive financial compensation for your items.
Think of a personally procured move (PPM) as a "Do-It-Yourself" move within the military. You will be responsible, for either packing/unpacking and transporting your belongings to your new location yourself or hiring your own commercial moving company. You can use a pod, U-Haul, or any other method of your choosing to conduct a PPM.
As an incentive to move yourself, the government will pay you 95% of their cost to hire a moving company on your behalf or perform your own move. If you can move your belongings yourself for less money, you get to keep the difference. Remember, this money is considered an incentive and is based on the household goods weight you actually transport, not to exceed your authorized weight allowance. If necessary, for most branches of Military Service you can receive an advance payment of up to 60% of the incentive value. Calculate your estimated PPM incentive for an upcoming move.
PPMs are especially recommended for any irreplaceable valuables you own (i.e. family heirlooms, photos, important documents, etc) or for necessities you will need immediately at your new location while waiting for your transporter to arrive.
*PPMs for OCONUS Permanent Change of Duty Station Moves are generally reserved for situations where the government does not have the resources to arrange a household goods move.
Did You Know: If the government cannot arrange a Household Goods (HHG) move within the timeframe requested, you can do a PPM and in some cases receive reimbursement of the actual cost associated with hiring a commercial moving company if approved in advance by your military service.
Unaccompanied baggage (UB) is an option for shipments where a small subset of your total weight allowance is expedited to your new location, typically while you wait for the rest of your belongings to arrive at a later date.
If you are travelling within the 48 contiguous states, the government requires you to drive your car to your new location or to pay for shipment at your own expense. The government will reimburse you for the mileage as well as any toll expenses you encounter along the way, so be sure to save receipts/tickets. In some cases, service members may be able to get a waiver to allow for vehicle shipment if a medical condition prevents them from sitting for long distances or if the report date makes it geographically impossible to drive with the allotted period of time.
Privately Owned Vehicle Shipments (POV) can be booked at PCSMyPOV.
Non-temporary storage (NTS) is long-term storage of your belongings used generally instead of shipping your items to your new duty station. Expect the storage location to be located near the origin (pickup) location where items may remain for the duration of your tour. When you return and have established a new address, you can request retrieval and shipment of your stored belongings. There may be restrictions on CONUS NTS, so be sure to contact your local personal property office if you have any questions.
When you change duty stations, making arrangements to move your pets can be as complicated as moving your family and household goods. Regardless of whether you're driving across the U.S. or flying overseas, all pet owners should plan ahead to make the trip less stressful for their furry companions. Here are some helpful tips for Transporting Your Pet. If you have questions about moving your pet under a permanent change of station order, please email us at transcom.scott.tcj5j4.mbx.pt1@mail.mil.
The rank specified on your job/travel orders will be used to determine how much total weight or moving allowance (a.k.a. "how much stuff") you are allowed to take to your new location. In general, as your rank increases, your moving allowance also increases. Any cost to move items/weight above a service member's moving allowance will be charged to the service member after delivery.
Learn your weight allowance (entitlements).

MONTGOMERY, Ala. — The former top Alabama judge known for refusing to remove a Ten Commandments monument from the state courthouse said Tuesday that he's seeking to regain his old job as chief justice of the Alabama Supreme Court.
Eight years after Roy Moore was removed from the post because of the monument dispute, he announced that he would run for the position again at a news conference on the steps of the Alabama Judicial Building in Montgomery. The 64-year-old Republican addressed the dispute in his remarks to the media and a couple dozen supporters.
"I have no plans to move the monument to Montgomery," he said, but added that he will continue to acknowledge God.
Current Chief Justice Chuck Malone and Charlie Graddick, a former attorney general who's now a circuit judge in Mobile, are already running in the Republican primary on March 13. No Democrat has announced.
Moore has said that lots of people have encouraged him to enter the Republican primary. He said he does not believe getting in the race behind the other two GOP candidates will hurt him, adding that he is well-known and voters know his judicial philosophy is conservative.
"There is no question that I know this job," Moore said during Tuesday's announcement. "And I believe the people of Alabama know exactly what I stand for."
Moore pointed to his previous experience as chief justice, including keeping the courts open despite what he said were significant budget cuts. He also said the court under his leadership effectively outlawed gambling machines in Alabama, ended an occupational tax in Montgomery County, and stopped a long-running school equity funding lawsuit.
Moore became a judge in 1992 when Republican Gov. Guy Hunt appointed him to a vacant circuit judgeship in Gadsden. He attracted national attention in a legal battle with the American Civil Liberties Union over his practice of opening court sessions with prayer and displaying a homemade plaque of the Ten Commandments in his courtroom.
After being elected chief justice in 2000, he had a 5,280-pound granite monument of the Ten Commandments installed in the lobby of the state judicial building in Montgomery. That set off more legal battles, which he lost. A trial court for judges removed him in 2003 over his refusal to abide by a federal judge's order to remove the display.
The monument currently sits at a church and school in Gadsden.
Moore said Tuesday that the monument fight was never about a piece of granite.
"It was never about the Ten Commandments," he said. "It was about the one who gave the Ten Commandments."
Since getting kicked out as chief justice, Moore has made two runs for governor. He lost the 2006 Republican primary to incumbent Bob Riley and finished fourth in the GOP primary 2010.
Moore said Tuesday that he is looking forward to yet another statewide campaign.
"Win or lose, you make a difference when you talk about the issues," he said.
In the spring, he formed an exploratory committee to consider a Republican run for president, but dropped it. Moore has said he drew good crowds during speaking engagements in Iowa, the first caucus state, and South Carolina, an early primary state, but couldn't generate the money needed to seriously consider a campaign.


A YouGov poll on voting intentions for the euro-elections, published in today's Times, puts UKIP on 27 percent, one point ahead of Labour on 26 percent. The Conservatives are put third with 22 percent of the vote and the Lib-Dems drop into fifth place at nine percent, behind the Green Party with ten percent.
On the other hand, an Opinium poll for the Daily Mail puts UKIP on 32 percent, against Labour's 25 percent, with the Conservatives on 21 percent. The Lib-Dems were said to be battling the Greens for fourth place, each on 6 percent.
A few days previously, though, with fieldwork completed on 19 May, another YouGov poll puts Labour first on 28 percent (up from 27), UKIP second on 24 percent (down from 26), the Conservatives on 21 (down from 23), the Lib-Dems on 10 (up from 9). The Greens had come up with 12 percent, an increase on three points. The BNP was scarcely registering with one percent.
At the same time, the Mirror announced its own poll, putting UKIP on 32 percent, with Labour on 27 percent, the Conservatives on 23 percent and the Lib-Dems on 9 percent.
Thus, what is of interest in an election that is cast as possibly attracting only 27 percent of the electorate, is the jockeying for first place between Labour and UKIP, with the narrowness of the margins and the obvious volatility making it impossible to predict the outcome with any confidence.
With that in mind, though, it is as well to remind ourselves of what these euro-elections are all about – an exercise which is as close to the concept of "democracy" as the EU ever comes – which is not very.
Certainly, there is nothing "democratic" about Mr Cameron's "top table", the Council of Ministers. There, when a vote is called, qualified majority voting (QMV) applies. Britain has 29 votes out of 352, representing eight percent of the vote. A qualified majority is 252 votes (73.9 percent), leaving Britain with a structural deficit of 223 votes.
However, in the European Parliament, the situation is little better. There are 73 UK MEPs, and these represent a mere 9.7 percent of the 751 elected MEPs (post-2014 election). Given the party splits, this level of representation is notional. UK MEPs rarely vote together as a single bloc. Even if they did, they could never muster the 376 votes needed for a majority.
Furthermore, the powers of the Parliament and the Council are limited in important but poorly recognised ways. As an increasing number of laws come into being via international standards, these are most often implemented by the EU as delegated legislation (Commission Regulations) using the comitology procedure.
Every year, more than 2,500 measures are processed via this route, passing through one or more of the 200-300 committees set up for the purpose. That is approximately 30 times more measures than are processed via the mainstream ordinary legislative procedure.
The committees themselves are populated by anonymous officials from the member states, but they have no powers to amend or reject Commission proposals. They can either approve them, or refer them to the Council if they disagree with them.
At Council, though, 70-90 percent of decisions are made by officials in the 160-plus preparatory bodies. These are known as "A-points" – colloquially the "A-list" – which are adopted by Ministers without discussion or a vote.
With Regulations made under acts passed before the Lisbon Treaty, the Council or Parliament can veto measures on certain grounds. That changes, though, with Regulations made under legislation approved post-Lisbon. The veto no longer applies.
Here, we now have a situation where the Commission only has to "review" proposed regulations if there are objections. There is no obligation for it to change them. After carrying out the review, the Commission can then go ahead and implement them.
Then, via the REFIT programme, the Commission is updating pre-Lisbon legislation, with the aim of eliminating the veto altogether. Britain (and Member States generally), with already limited power, are thereby weakened even more.
And this is, supposedly what we're voting for today … the day the people are supposed to get their say in the running of "Europe".
Like talking to the BBC, playing their game only makes us their stooges. In reality, splitting up 9.7 percent of the vote between a group of dysfunctional political parties, to let them play in an institution that hasn't any real power anyway, is something for which it isn't even worth getting out of bed.

'Short Transit' returns with a twist
"Berlin Jaffa - Short Transit" from the Israeli De De Dance Company and the Berlin-based Wee Dance Company is returning for a series of performances mostly in Israel's provincial towns.
By HELEN KAYE
"Berlin Jaffa - Short Transit" from the Israeli De De Dance Company and the Berlin-based Wee Dance Company is returning for a series of performances mostly in Israel's provincial towns from March 4-21. The twist is that in each place there'll be a community project with some students from the various local dance schools. Over the last six months De De met with these students, gave them new insights and taught them new material from both the Israeli and the German companies. Participating students will also take part in the performance in their town. Additionally guest choreographers, dancers and companies will also join the tour in various places, such as Renena Raz, Sahar Azimi and the Nadine Bommer Dance Company. There will be shows in Kadima (4/3), Or Yehuda (5/3), Upper Nazareth (7/3), Jerusalem Ma'abada (8/3) Karmiel (16/3), Herzliya (18/3) Kiryat Gat (19/3) and at Suzanne Dellal in Tel Aviv on 21/3.

Q: can I store the next route complete with path variables? I am implementing deep linking in a system using angular. (User follows link in to system, gets login screen, authenticates, then next step is the page they requested with the link (as opposed to the generic fresh-login-start page)).
In the $routeChangeStart event handler I store the next route location in the cookie. After the user authenticates I retrieve the location and send them there.
It works fine for urls without any path variables. For example, if they were trying to get to mydomain.com/viewAllServices then they go to the location post login.
It does not work for urls with path variables. For example, if they were trying to get to mydomain.com/service/123 then post login, they go to mydomain.com/service/:serviceId
I can see the parameters in the next.params and next.pathParams objects in my $routeChangeStart event handler. I can figure out how to replace them programatically, but I wonder if there is a friendlier part of the angular interface that I should be using.
Has anyone else implemented this? Is it necessary to put the values in the url using regex?

Stormbreaker: A Storm on England
UWrite - U Report
Jun 10, 2019 By Divyansh, 12
In Stormbreaker, the original realistic novel in Anthony Horowitz's bestselling "Alex Rider" series, the protagonist, 14-year-old orphan Alex Rider, was told by London police that his guardian uncle, Ian Rider, was killed by a truck.
He later discovered his uncle had been a spy working for England's MI6 (international intelligence agency). Still reeling from the loss, Alex is contacted by MI6 and asked to finish his uncle's mission at Sayle Enterprises. Because the British agency wanted to breach building security, they needed an unsuspicious associate like him.
Alex was sent to Sayle Enterprises in Cornwall to spy and report back to MI6. MI6 wanted the information his assassinated uncle had uncovered. Ian was sent to Cornwall because Sayle was manufacturing Stormbreakers, the most advanced computer ever made (which he had designed), and was donating one to every British school. MI6 thought this generosity seemed "too good to be true."
After discovering an ominous secret hidden in the computer hardware, Alex was about to report this shocking discovery to MI6 when he was captured by Sayle's security guard. Will he narrowly escape captivity? Will he manage to save England's schoolchildren?
Action-packed Storyline
Horowitz keeps back-to-back action, not allowing the reader to lose interest while still displaying the characters' emotions and internal thoughts. In addition to expertly keeping readers hooked throughout the story, the author includes realistic dialogue and humor for a typical teenage boy.
I recommend Stormbreaker to middle school readers who enjoy thrilling plots with always-looming danger, quick and daring decisions, cool concealed gadgets, and nonstop action. I couldn't let go of this breathtaking book and am sure many of you will agree.

Washington, D.C. – Today, U.S. Rep. Gus Bilirakis (FL-12), Vice Chairman of the House Veterans' Affairs (VA) Committee, introduced the Pups for Patriots Act. This legislation promotes the use of service dogs for Veterans by establishing a new VA pilot program working with nonprofit service dog organizations.
"The benefits of service dog therapy can in some ways go beyond anything that comes in a pill bottle. My legislation would help support service dog therapy as an alternative treatment by connecting the VA to the many qualified nonprofits nationwide who train and provide service dogs. Many of us have known the unconditional love dogs bring to our lives. This bond can do wonders to help our nation's heroes as they deal with their invisible wounds," said Bilirakis.
This is not the first time Bilirakis has advocated for alternative treatments for Veterans. Last year, his bill, the COVER Act, was signed into law to promote treatments like outdoor sports therapy, hyperbaric oxygen therapy, accelerated resolution therapy, and more.
